Burj Dubai @ Burj Khalifa

Burj Khalifa (Arabic: برج خليفة‎ "Khalifa Tower"), known as Burj Dubai prior to its inauguration, is a skyscraper in Dubai, United Arab Emirates, and the tallest man-made structure ever built, at 828 m (2,717 ft). Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010. The building is part of the 2 km2 (490-acre) flagship development called Downtown Burj Khalifa at the "First Interchange" along Sheikh Zayed Road, near Dubai's main business district.


The tower's architecture and engineering were performed by Skidmore, Owings, and Merrill of Chicago. Adrian Smith, who started his own firm (Adrian Smith + Gordon Gill Architecture) in 2006, was the chief architect, and Bill Baker was the chief structural engineer for the project. The primary contractor was Samsung C&T of South Korea, who also built the Taipei 101 and Petronas Twin Towers. Major subcontractors included Belgian group Besix and Arabtec from the UAE. Turner Construction Company was chosen as the construction project manager. Under UAE law, the Contractor and the Engineer of Record, Hyder Consulting, is jointly and severally liable for the performance of Burj Khalifa.

The total cost for the Burj Khalifa project was about US$1.5 billion; and for the entire new "Downtown Dubai", US$20 billion. Mohamed Ali Alabbar, the Chairman of Emaar Properties, speaking at the Council on Tall Buildings and Urban Habitat 8th World Congress, said in March 2009 that the price of office space at Burj Khalifa had reached US$4,000 per sq ft (over US$43,000 per m2) and that the Armani Residences, also in Burj Khalifa, were selling for US$3,500 per sq ft (over US$37,500 per m2).

The project's completion coincided with a worldwide economic slump and overbuilding, and it has been described as "the latest ... in a string of monuments to architectural vacancy." With Dubai itself mired in a deep financial crisis that forced it to seek repeated billion-dollar bailouts from its oil-rich neighbor Abu Dhabi, the opening ceremony and surprise renaming of the tower to Burj Khalifa, after UAE President Khalifa bin Zayed Al Nahyan, has been viewed by observers as an "attempt to boost confidence in Dubai by showing who is backing Dubai".

There are unconfirmed reports of several planned height increases since its inception. Originally proposed as a virtual clone of the 560 m (1,837 ft) Grollo Tower proposal for Melbourne, Australia's Docklands waterfront development, the tower was redesigned with an original design by Skidmore, Owings and Merrill (SOM) discussed below. Marshall Strabala, an SOM architect who worked on the project until 2006, late 2008 said that Burj Khalifa was designed to be 808 m (2,651 ft) tall.


The design architect, Adrian Smith, felt that the uppermost section of the building did not culminate elegantly with the rest of the structure, so he sought and received approval to increase it to the current height.[citation needed] It has been explicitly stated that this change did not include any added floors, which is fitting with Smith's attempts to make the crown more slender.
Emaar Properties announced on 9 June 2008 that construction of Burj Khalifa was delayed by upgraded finishes and would be completed only in September 2009. An Emaar spokesperson said "The luxury finishes that were decided on in 2004, when the tower was initially conceptualized, is now being replaced by upgraded finishes. The design of the apartments has also been enhanced to make them more aesthetically attractive and functionally superior." A revised completion date of 2 December 2009 was then announced. However, Burj Khalifa was opened on 4 January 2010.

The tower is designed by Skidmore, Owings and Merrill, which also designed the Willis Tower (formerly the Sears Tower) in Chicago, Illinois and 1 World Trade Center in New York City, among numerous other famous high-rises. The building resembles the bundled tube form of the Willis Tower, but is not a bundle tube structure. Its design is reminiscent of Frank Lloyd Wright's vision for The Illinois, a mile-high skyscraper designed for Chicago. According to Marshall Strabala, an SOM architect who worked on the building's design team, Burj Khalifa was designed based on the 73-floor Tower Palace Three, an all-residential building in Seoul, South Korea. In its early planning, Burj Khalifa was intended to be entirely residential.


Subsequent to the original design by Skidmore, Owings and Merrill, Emaar Properties chose Hyder Consulting to be the supervising engineer. Hyder was selected for its expertise in structural and MEP (mechanical, electrical and plumbing) engineering. Hyder Consulting's role was to supervise construction, certify SOM's design, and be the engineer and architect of record to the UAE authorities. Emaar Properties also engaged GHD, an international multidisciplinary consulting firm, to act as an independent verification and testing authority for concrete and steelwork.

The design of Burj Khalifa is derived from patterning systems embodied in Islamic architecture. According to the structural engineer, Bill Baker of SOM, the building's design incorporates cultural and historical elements particular to the region. The Y-shaped plan is ideal for residential and hotel usage, with the wings allowing maximum outward views and inward natural light. The design architect, Adrian Smith, has said the triple-lobed footprint of the building was inspired by the flower Hymenocallis. The tower is composed of three elements arranged around a central core. As the tower rises from the flat desert base, setbacks occur at each element in an upward spiralling pattern, decreasing the cross section of the tower as it reaches toward the sky. There are 27 terraces in Burj Khalifa. At the top, the central core emerges and is sculpted to form a finishing spire. A Y-shaped floor plan maximizes views of the Persian Gulf. Viewed from above or from the base, the form also evokes the onion domes of Islamic architecture. During the design process, engineers rotated the building 120 degrees from its original layout to reduce stress from prevailing winds. At its tallest point, the tower sways a total of 1.5 m (4.9 ft).

To support the unprecedented height of the building, the engineers developed a new structural system called the buttressed core, which consists of a hexagonal core reinforced by three buttresses that form the ‘Y' shape. This structural system enables the building to support itself laterally and keeps it from twisting.

The spire of Burj Khalifa is composed of more than 4,000 tonnes (4,400 ST; 3,900 LT) of structural steel. The central pinnacle pipe weighing 350 tonnes (390 ST; 340 LT) was constructed from inside the building and jacked to its full height of over 200 m (660 ft) using a strand jack system. The spire also houses communications equipment.

More than 1,000 pieces of art will adorn the interiors of Burj Khalifa, while the residential lobby of Burj Khalifa will display the work of Jaume Plensa, featuring 196 bronze and brass alloy cymbals representing the 196 countries of the world. The visitors in this lobby will be able to hear a distinct timbre as the cymbals, plated with 18-carat gold, are struck by dripping water, intended to mimic the sound of water falling on leaves.

The exterior cladding of Burj Khalifa consists of 142,000 m2 (1,528,000 sq ft) of reflective glazing, and aluminium and textured stainless steel spandrel panels with vertical tubular fins. The cladding system is designed to withstand Dubai's extreme summer temperatures. Additionally, the exterior temperature at the top of the building is thought to be 6°C (11°F) cooler than at its base. Over 26,000 glass panels were used in the exterior cladding of Burj Khalifa. Over 300 cladding specialists from China were brought in for the cladding work on the tower.

An Armani Hotel, the first of four by Armani, occupies 15 of the lower 39 floors. The hotel was supposed to open on 18 March 2010 but after several delays the hotel finally opened the public on 27 April 2010. The corporate suites and offices, were also supposed to open from March onwards but the hotel and observation deck remain the only parts of the building which are open.

The sky lobbies on the 43rd and 76th floors will house swimming pools. Floors through to 108 will have 900 private residential apartments (which, according to the developer, sold out within eight hours of being on the market). An outdoor zero-entry swimming pool will be located on the 76th floor of the tower. Corporate offices and suites fill most of the remaining floors, except for a 122nd, 123rd and 124th floor where the At.mosphere restaurant, sky lobby and an indoor and outdoor observation deck is located respectively. Burj Khalifa will receive its first residents from February 2010. They will be among the first of 25,000 people who will live there.

Burj Khalifa is expected to hold up to 35,000 people at any one time. A total of 57 elevators and 8 escalators are installed. The elevators have a capacity of 12 to 14 people per cabin, the fastest rising and descending at up to 18 m/s (59 ft/s). Engineers had considered installing the world's first triple-deck elevators, but the final design calls for double-deck elevators. Double-deck elevators, are with built in light and entertainment features including LCD displays, which serves the visitors throughout their travel to the observation deck. The building has 2,909 stairs from the ground floor to the 160th floor.

The graphic design identity work for Burj Khalifa is the responsibility of Brash Brands, who are based in Dubai. Design of the global launch events, communications, and visitors centers[56] for Burj Khalifa have also been created by Brash Brands as well as the roadshow exhibition for the Armani Residences, which are part of the Armani Hotel within Burj Khalifa, which toured Milan, London, Jeddah, Moscow and Delhi.
The Burj Khalifa's water system supplies an average of 946,000 l (250,000 USgal) of water per day.
At the peak cooling times, the tower requires cooling equivalent to that provided by 10,000 t (22,000,000 lb) of melting ice in one day. The building has a condensate collection system, which uses the hot and humid outside air, combined with the cooling requirements of the building and results in a significant amount of condensation of moisture from the air. The condensed water is collected and drained into a holding tank located in the basement car park, this water is then pumped into the site irrigation system for use on the Burj Khalifa park.

To wash the 24,348 windows, a horizontal track has been installed on the exterior of Burj Khalifa at levels 40, 73 and 109. Each track holds a 1,500 kg (3,300 lb) bucket machine which moves horizontally and then vertically using heavy cables. Above level 109, up to tier 27 traditional cradles from davits are used. The top of the spire, however, is reserved for specialist window cleaners, who brave the heights and high winds dangling by ropes to clean and inspect the top of the pinnacle.[58] Under normal conditions, when all building maintenance units will be operational, it will take 36 workers three to four months to clean the entire exterior facade.

Unmanned machines will clean the top 27 additional tiers and the glass spire. The cleaning system was developed in Australia at a cost of A$8 million.

Outside, and at a cost of Dh 800 million (US$217 million), a record-setting fountain system was designed by WET Design, the California-based company responsible for the fountains at the Bellagio Hotel Lake in Las Vegas. Illuminated by 6,600 lights and 50 coloured projectors, it is 275 m (902 ft) long and shoots water 150 m (490 ft) into the air, accompanied by a range of classical to contemporary Arabic and world music. On 26 October 2008 Emaar announced that based on results of a naming contest the fountain would be called the Dubai Fountain.
 
An outdoor observation deck, named At the Top, opened on 5 January 2010 on the 124th floor. It is the third highest observation deck in the world and the highest outdoor observation deck in the world, at 442 m (1,450 ft)[citation needed]. To manage the daily rush of sightseers, Emaar Properties offers advance purchase tickets for a specific date and time at a 75% discount over tickets purchased on the spot.


On 8 February 2010, the observation deck was closed to the public after power supply problems caused an elevator to become stuck between floors, trapping a group of tourists for 45 minutes. Despite rumours of the observation deck reopening for St. Valentines Day (14 February), it remained closed until 4 April 2010.

Burj Khalifa is surrounded by an 11 ha (27-acre) park designed by landscape architects SWA Group. The design of the park is also inspired by the core design concepts of Burj Khalifa which is based on the symmetries of the desert flower, Hymenocallis. The park has six water features, gardens, palm lined walkways, and flowering trees. At the centre of the park and the base of Burj Khalifa is the water room, which is a series of pools and water jet fountains. In addition the railing, benches and signs incorporate images of Burj Khalifa and the Hymenocallis flower.


The plants and the shrubbery will be watered by the buildings's condensation collection system,that uses water from the cooling system. The system will provide 68,000,000 L (15,000,000 imp gal) annually. WET designers, who also developed the Dubai Fountain, developed the park's six water features.

The tower was constructed by a South Korean company, Samsung Engineering & Construction, which also did work on the Petronas Twin Towers and Taipei 101. Samsung Engineering & Construction is building the tower in a joint venture with Besix from Belgium and Arabtec from UAE. Turner is the Project Manager on the main construction contract.


The primary structural system of Burj Khalifa is reinforced concrete. Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes (120,000 ST; 110,000 LT) were used to construct the concrete and steel foundation, which features 192 piles, with each pile is 1.5 metre diameter x 43 metre long buried more than 50 m (164 ft) deep.[23] Burj Khalifa's construction used 330,000 m3 (431,600 cu yd) of concrete and 55,000 tonnes of steel rebar, and construction took 22 million man-hours. A high density, low permeability concrete was used in the foundations of Burj Khalifa. A cathodic protection system under the mat is used to minimize any detrimental effects from corrosive chemicals in local ground water.

The previous record for pumping concrete on any project was set during the extension of the Riva del Garda Hydroelectric Power Plant in Italy in 1994, when concrete was pumped to a height of 532 m (1,745 ft). Burj Khalifa exceeded this height on 19 August 2007, and as of May 2008 concrete was pumped to a delivery height of 606 m (1,988 ft), the 156th floor. The remaining structure above is built of lighter steel.

Burj Khalifa is highly compartmentalised. Pressurized, air-conditioned refuge floors are located approximately every 35 floors where people can shelter on their long walk down to safety in case of an emergency or fire.

Special mixes of concrete are made to withstand the extreme pressures of the massive building weight; as is typical with reinforced concrete construction, each batch of concrete used was tested to ensure it could withstand certain pressures.

The consistency of the concrete used in the project was essential. It was difficult to create a concrete that could withstand both the thousands of tonnes bearing down on it and Persian Gulf temperatures that can reach 50 °C (122 °F). To combat this problem, the concrete was not poured during the day. Instead, during the summer months ice was added to the mixture and it was poured at night when the air is cooler and the humidity is higher. A cooler concrete mixture cures evenly throughout and is therefore less likely to set too quickly and crack. Any significant cracks could have put the entire project in jeopardy.

The unique design and engineering challenges of building Burj Khalifa have been featured in a number of television documentaries, including the Big, Bigger, Biggest series on the National Geographic and Five channels, and the Mega Builders series on the Discovery Channel.

Burj Khalifa was built primarily by workers from South Asia. Press reports indicated in 2006 that skilled carpenters at the site earned UK£4.34 a day, and labourers earned UK£2.84. According to a BBC investigation and a Human Rights Watch report, the workers were housed in abysmal conditions, their pay was often withheld, their passports were confiscated by their employers, and they were working in hazardous conditions that resulted in an apparently high number of deaths and injuries on site.

On 21 March 2006, about 2,500 workers, who were upset over buses that were delayed for the end of their shifts, protested, damaging cars, offices, computers, and construction equipment. A Dubai Interior Ministry official said the rioters caused almost UK£500,000 in damage. Most of the workers involved in the riot returned the following day but refused to work.

On 17 June 2008, there were 7,500 skilled workers employed in the construction of Burj Khalifa.

The opening ceremony of Burj Khalifa was held on 4 January 2010. The ceremony featured a display of 10,000 fireworks, light beams projected on and around the tower, and further sound, light and water effects. Using the 868 powerful stroboscope lights that are integrated into the facade and spire of the tower, different lighting sequences were choreographed, together with more than 50 different combinations of the other effects.


The event began with a short film which depicted the story of Dubai and the evolution of Burj Khalifa. The displays of sound, light, water and fireworks followed. The portion of the show consisting of the various pyrotechnic, lighting, water and sound effects was divided into three. The first part was primarily a light and sound show, which took as its theme the link between desert flowers and the new tower, and was co-ordinated with the Dubai Fountain and pyrotechnics. The second portion, called 'Heart Beat', represented the construction of the tower in a dynamic light show with the help of 300 projectors which generated a shadow-like image of the tower. In the third act, sky tracers and space cannons enveloped the tower in a halo of white light, which expanded as the lighting rig on the spire activated.

The ceremony was relayed live on a giant screen on Burj Park Island, as well as several television screens placed across the Downtown Burj Khalifa development. Hundreds of media outlets from around the world reported live from the scene. In addition to the media presence, 6,000 guests were expected.

Burj Khalifa has been designed to be the centrepiece of a large-scale, mixed-use development that will include 30,000 homes, nine hotels such as The Address Downtown Burj Khalifa, 3 hectares (7.4 acres) of parkland, at least 19 residential towers, the Dubai Mall, and the 12-hectare (30-acre) man-made Burj Khalifa Lake.


The building has returned the location of Earth's tallest free-standing structure to the Middle East — where the Great Pyramid of Giza claimed this achievement for almost four millennia before being surpassed in 1311 by Lincoln Cathedral in England.

The decision to build Burj Khalifa is reportedly based on the government's decision to diversify from an oil-based economy to one that is service- and tourism-oriented. According to officials, it is necessary for projects like Burj Khalifa to be built in the city to garner more international recognition, and hence investment. "He (Sheikh Mohammed bin Rashid Al Maktoum) wanted to put Dubai on the map with something really sensational," said Jacqui Josephson, a tourism and VIP delegations executive at Nakheel Properties.

The building has been used by several experienced BASE jumpers for both authorized and unauthorized BASE jumping:

  • In May 2008, Hervé Le Gallou and an unnamed British man, dressed as engineers, illegally infiltrated Burj Khalifa (around 650 m at the time), and jumped off a balcony situated a couple of floors below the 160th floor.
  • On 8 January 2010, with permission of the authorities, Nasr Al Niyadi and Omar Al Hegelan, from the Emirates Aviation Society, broke the world record for the highest BASE jump from a building after they leapt from a crane suspended platform attached to the 160th floor at 672 m (2,205 ft). The two men descended the vertical drop at a speed of up to 220 km/h (140 mph), with enough time to open their parachutes 10 seconds into the 90 second jump.

“IHSAN MEMPERKASA JATIDIRI PEKERJA ” (30 APRIL 2010 / 15 JAMADIL AWWAL 1431)

Pada hari Jumaat yang berkat ini, dikenali juga sebagai Penghulu segala hari, maka saya berpesan kepada diri saya dan menyeru kepada sidang Jumaat yang dikasihi sekalian, marilah sama-sama kita berterusan bertakwa kepada Allah SWT, takut kepada Allah dengan menghayati segala perintah-Nya dan menjauhi segala larangan-Nya. Mudah-mudahan dengan ketakwaan itu, akan mewujudkan anak-anak dan keluarga kita yang menjadi asas kekuatan masyarakat ini menjadi insan soleh serta membawa kesejahteraan di dunia dan akhirat. Tajuk khutbah Jumaat pada hari ini ialah: “IHSAN MEMPERKASA JATIDIRI PEKERJA”.




Dalam al-Quran diterangkan bahawa Allah SWT menciptakan manusia dan jin adalah untuk beribadah dan menjadi hamba Allah iaitu menguruskan dunia ini dengan sebaik mungkin mengikut standard piawaian atau peraturan yang ditetapkan-Nya. Selepas itu manusia akan dikembalikan ke akhirat untuk menghadapi penilaian dan pengadilan sejauhmana prestasi melaksanakan perintah Allah SWT. Inilah matlamat utama dan halatuju kehidupan manusia di dunia ini.

Sebagai pekerja Allah di atas dunia ini samada bekerja dengan kerajaan, swasta dan bekerja sendiri , mereka mempunyai tugas dan tanggungjawab tertentu. Menurut ajaran Islam, pada dasarnya setiap pekerjaan orang Islam mempunyai dua sasaran utama : Pertama melaksanakan hak Allah SWT dan Keduanya melaksanakan muamalah sesama manusia seperti dalam politik, undang-undang, pendidikan, ekonomi, pertanian, kesihatan dan sebagainya. Mimbar amat yakin jika umat Islam dapat memenuhi dengan cemerlang melaksanakan dua sasaran itu maka umat Islam akan memperolehi kejayaan hidup di dunia dan akhirat.

Bagaimanapun isu yang sering menjadi perbahasan hangat mengenai pekerja ialah kualiti pekerjaan dan kecemerlangan dalam usaha memberi perkhidmatan yang memuaskan kepada dua pelanggan tadi iatu Allah SWT dan manusia.

Islam telah memberi peringatan kepada umatnya supaya sentiasa berbuat baik, cemerlang dan menjaga kualiti atau bersifat ihsan dalam melakukan setiap pekerjaan. Firman Allah SWT dalam surah al-Qasas ayat 77:




Maksudnya: “ Dan berbuat baiklah kepada orang lain sebagaimana Allah berbuat baik kepadamu; dan janganlah engkau melakukan kerosakan di muka bumi; sesungguhnya Allah tidak suka kepada orang yang berbuat kerosakan”.


Ketika mengulas perkara yang sama mengenai kecemerlangan dalam melaksanakan sesuatu pekerjaan, Rasulullah SAW bersabda:



Mafhumnya: “Sesungguhnya Allah azza wajalla sangat suka (bahkan cinta) jika seseorang daripada kamu, apabila melakukan kerja, maka dia bekerja dengan tekun.(Riwayat Baihaqi)”

Muslimin Yang di Rahmati Allah,

Dalam hadith terkenal yang diriwayatkan al-Bukhari menyatakan Malaikat Jibril mengajar Rasulullah SAW tentang perihal Rukun Iman, Rukun Islam dan Ihsan. Jika salah satu komponen ini tidak ada atau tidak difahami, maka kita belum menghayati Islam secara sempurna.

Berdasarkan pemerhatian mimbar, memahami dan menghayati sifat ihsan ini akan membantu umat Islam mewujudkan pekerjaan yang cemerlang dan berkualiti tinggi. Sifat ihsan bermaksud kita melaksanakan sesuatu pekerjaan untuk mengabdikan diri kepada Allah SWT dengan perasaan yakin seolah-olah pekerjaan kita dilihat dan dipantau oleh Allah SWT. Sabda Rasullullah SAW ketika di tanya oleh Jibril tentang ihsan:



Maksudnya: “ Apakah ihsan itu?, sesungguhnya kamu menyembah Allah seolah-olah kamu melihat-Nya, tetapi jika kamu tidak melihat-Nya, maka sesungguhnya Dia melihat kamu”. ( Riwayat al-Bukhari )

Unsur penting sifat ihsan ialah bekerja secara profesional, menguasai bidang kerja, kreatif dan inovatif untuk menghasilkan kualiti kerja yang tinggi. Penghasilan yang baik sudah tentu menjadi hak pekerja dan memberi kepuasan kepada pelanggan. Persoalan besar timbul ialah bagaimana cara untuk melahirkan ihsan atau sebaik-baik pekerjaan yang amat dituntut dalam Islam itu?. Berdasarkan dalil al-Quran, hadith Rasulullah dan pakar pengurusan, prinsip ihsan meliputi perkara berikut:

Pertama: Berakhlak mulia,

Kedua: Kita perlu mempunyai keterampilan dan kemahiran tinggi dalam sesuatu bidang tugas,

Ketiga: Mempunyai ilmu pengetahuan dan pengalaman serta kecerdasan dalam menganalisis sesuatu maslahah dan peka dengan keperluan masyarakat semasa,

Keempat: Mempunyai wawasan dan dapat membuat jangkaan tentang keperluan masa depan,

Kelima: Mempunyai keyakinan diri yang tinggi dalam menghasilkan kecemerlangan sesuatu aktiviti.

Prinsip ihsan tidak berhasil jika semata-mata kuat beragama tetapi tidak menguasai ilmu dan kemahiran pekerjaan. Prinsip ihsan juga akan cacat jika hebat menguasai ilmu tetapi lemah dalam penghayatan agama. Berdasarkan pengertian sebenar sifat ihsan ini, akan melahirkan pekerja yang bertanggungjawab, beristiqamah dengan suruhan Allah SWT dan sekaligus mengutamakan kepentingan pelanggan dalam melakukan tugasannya, samada ketika berhadapan dengan orang ramai atau di tempat yang sunyi, samada ketika bersama dengan majikan ataupun ketika ketiadaan majikan.

Pekerja yang melaksanakan tugas mengikut bidang yang ditetapkan dengan penuh ihsan dijanjikan pahala yang besar daripada Allah SWT. Firman Allah SWT dalam surah al-Baqarah ayat 112:

Maksudnya, ”Sesiapa yang menyerahkan dirinya kepada Allah (mematuhi perintahNya) sedang ia pula berusaha supaya baik amalannya, maka ia akan beroleh pahalanya di sisi Tuhannya, dan tidaklah ada kebimbangan (dari berlakunya kejadian yang tidak baik) terhadap mereka, dan mereka pula tidak akan berdukacita”.

Muslimin yang di Rahmati Allah,

Mimbar mengingatkan bahawa kecemerlangan sesebuah organisasi itu tidak akan datang bergolek tanpa usaha yang gigih, tidak datang melayang tanpa tekad dan azam yang kuat dan tidak dapat kita capai tanpa ada perubahan ke arah peningkatan.

Selari dengan tuntutan ajaran Islam, Allah SWT telah menegur umat manusia supaya berani membuat perubahan positif dalam semua aspek kehidupan. Sikap ini dikenalpasti memajukan lagi prestasi dan kualiti keinsanan seseorang. Firman Allah SWT dalam surah ar-Ra’d ayat 11:


Maksudnya: “. Sesungguhnya Allah tidak mengubah apa yang ada pada sesuatu kaum sehingga mereka mengubah apa yang ada pada diri mereka sendiri..”

Bekerja atas dasar ihsan untuk memenuhi hak Allah SWT dan keperluan manusia sejagat akan memperkasa jati diri dan meningkatkan harga diri pekerja. Seseorang akan takut melakukan perbuatan keji, tercela seperti melakukan kerosakan, penipuan, rasuah, mencuri tulang, ponteng kerja, dan perbuatan negatif yang lain. Jangan mendapatkan rezeki atau kekayaan dengan sembarangan, dengan jalan haram, dengan jalan penipuan, rasuah, penyelewengan dan lain-lain.

Semua wang kekayaan yang didapati dengan cara haram apalagi dengan menganiaya pihak lain dengan merugikan orang lain adalah wang dan kekayaan yang tidak berkat. Kekayaan secara haram hakikatnya tidak membawa kesenangan dan kebahagian dalam hidup, tetapi akan membawa kesengasaraan dan kecelakaan di dunia dan akhirat. Jiwa manusia, jiwa pekerja pada asalnya adalah sesuatu yang suci. Tetapi harta yang diperolehi secara tidak halal tidak mungkin dapat memberi kebaikan pada jiwa kita.

Muslimin Yang di Rahmati Allah,

Mengakhiri khutbah, mimbar menyeru semua golongan pekerja, sempena sambutan Hari Pekerja 2010 yang bertemakan:Pekerja berinovasi pemacu tranformasi, maka marilah sama-sama kita memperkasa jati diri dengan menghayati sifat ihsan supaya setiap amalan dan pekerjaan kita memenuhi standard piawaian Allah dan memberi kepuasan kepada Allah SWT serta manusia sejagat.

Firman Allah SWT dalam surah at-Taubah ayat 105:



Maksudnya: “ Katakanlah (wahai Muhammad), beramallah kamu akan segala yang diperintahkan, maka Allah SWT. dan Rasul-Nya serta orang yang beriman akan melihat apa yang kamu kerjakan; dan kamu akan dikembalikan kepada Allah SWT. yang mengetahui perkara-perkara yang ghaib dan nyata. Kemudian Dia memberitahu kepada kamu apa yang kamu telah kerjakan.”

Enjin Campro

Enjin Campro ialah enjin kereta pertama yang dikeluarkan oleh pembuat kereta Malaysia, Proton dengan kerjasama Lotus. Nama Campro ialah kependekan bagi Cam Profile (Profil Sesondol). Enjin ini digunakan dalam model-model kereta Proton bermula dengan Proton Gen-2 diikuti model-model lain termasuk Proton Satria Neo, Proton Waja dan Proton Persona. Enjin ini dibina sebagai membuktikan kemampuan Proton untuk membina enjin yang berkuasa dan mematuhi piawaian emisi yang ketat.




Enjin Campro DOHC asas dikeluarkan dalam 2 sesaran enjin iaitu 1.6L (S4PH) dan 1.3L (S4PE). Semasa peringkat pembangunannya, enjin ini dipasang pada Proton Waja yang digunakan khas untuk ujian jalan raya. Enjin ini mula digunakan pada Proton     Gen-2. Walaupun enjin tersebut kelihatan berkuasa pada kelajuan enjin tinggi, namun pengguna awal Gen-2 mengalami masalah kekurangan kilasan terutamanya untuk mendaki bukit semasa kelajuan enjin sekitar 3,000 ~ 3,500 rpm disebabkan penurunan kilasan pada kelajuan tersebut sebelum meningkat semula ke 148 N-m pada 4,000 rpm. Akibatnya, pemandu terpaksa banyak menukar antara gear 2 dan 3 semasa mendaki bukit. Masalah ini diselesaikan dengan pemetaan semula ECU enjin tersebut pada tahun 2005.


S4PH

  • Kuasa kuda maksimum: 110 bhp (82 kW) @ 6,000 rpm
  • Kilasan maksimum: 148 N-m @ 4,000 rpm
  • Lubang x lejang: 76 x 88 mm
  • Sesaran enjin: 1598 cc


S4PE
  • Kuasa kuda maksimum: 94 bhp (70 kW) @ 6,000 rpm
  • Kilasan maksimum: 120 N-m @ 4,000 rpm
  • Lubang x lejang: 76 x 73.4 mm
  • Sesaran enjin: 1332 cc




Sebagai tambahan kepada enjin DOHC asas sedia ada, Proton juga sedang membangunkan enjin CPS (Penukaran Profil Sesondol) dan VIM (Rongga Masukan Boleh Laras). Teknologi CPS adalah teknologi pemasaan injap boleh laras yang dibangunkan serupa dengan teknologi VTEC oleh Honda dan VVT-i oleh Toyota, tetapi bezanya ialah CPS menukar profil sesondol dengan menggunakan tapet tindakan terus dengan pin pengunci manakala VTEC dan VVT-i pula menggunakan lengan jumpelang dengan pin pengunci. Mekanisme CPS bertindak pada 3,800 rpm, tetapi pada Proton Satria Neo CPS pula penukaran berlaku pada 4,400 rpm.


Enjin Campro CPS 1.6 mampu menghasilkan sehingga 125 kuasa kuda (127 PS; 93 kW) pada 6,500 rpm serta meningkatkan nilai kilasan kepada 150 N-m @ 4,500 rpm yang berterusan sehingga 5,000 rpm. Proses pembangunan enjin ini sering mendapat kritikan di kalangan peminat automotif kerana sering tertangguh walaupun jadual asal bagi penggunaan teknologi sedemikian sepatutnya mula digunakan pada tahun 2005. Enjin Campro CPS hanya akan mula digunakan bermula dengan model Proton Gen-2 dan Proton Waja tahun 2008.

Kedua-dua teknologi CPS dan VIM saling bergandingan dan berfungsi dalam 3 mod berbeza seperti berikut:-
  1. Kelajuan enjin rendah (3,800 rpm ke bawah): Sesondol rendah digunakan dan udara masuk melalui rongga masukan panjang untuk percampuran udara-bahan api yang lebih baik, seterusnya menjimatkan bahan api serta menghapuskan junaman kilasan pada rpm rendah.
  2. Kelajuan enjin sederhana (3,800 ~ 4,800 rpm): Sistem CPS menukar profil sesondol dari sesondol rendah ke sesondol tinggi, membolehkan lebih banyak campuran udara-bahan api masuk dengan lebih lawas, sekaligus menyumbang kepada kuasa maksimum yang lebih tinggi.
  3. Kelajuan enjin tinggi (4,800 rpm ke atas): Sistem VIM menukar aliran udara kepada rongga masukan pendek dan lurus.
Selain enjin 1.6L, enjin Campro CPS juga terdapat dalam versi 1.8L, tetapi setakat 30 April 2008 ia masih belum digunakan pada mana-mana model kereta Proton sebaliknya membuat penampilan sulungnya di dalam sebuah hoverkraf buatan Malaysia.

Secara ringkasnya, enjin Campro IAFM adalah enjin asas Campro DOHC yang dipasang dengan sistem rongga masukan boleh laras, dikenali sebagai modul IAFM (Modul Masukan Udara-Bahan Api), mula dibangunkan bersama-sama oleh Proton, Bosch dan EPMB pada April 2005. Walau bagaimanapun, perbezaan antara IAFM dengan sistem VIM pada enjin Campro CPS adalah seperti berikut:-

  1. IAFM adalah modul tunggal yang boleh dipasang terus pada enjin asas DOHC tetapi VIM pula perlu berfungsi seiringan dengan sistem CPS pada enjin CPS.
  2. IAFM berfungsi menggunakan tekanan vakum enjin manakala VIM berfungsi menggunakan solenoid elektrik kawalan ECU.
Enjin Campro IAFM mula digunakan pada generasi kedua Proton Saga yang dilancarkan pada Januari 2008. Enjin 1.3L tersebut mampu menghasilkan kuasa maksimum 98 bhp @ 6,500 rpm. Kilasan maksimum menurun sedikit kepada 113.2 N-m, tetapi banjaran kilasan pada enjin IAFM tersebut adalah lebih lebar serta masalah kemerosotan daya kilasan yang biasa dihadapi pada RPM pertengahan telah dapat ditangani sepenuhnya.

Sementara itu, versi 1.6 liter pula menghasilkan 110 bhp @ 6,500 rpm dan kilasan sekuat 148 N-m @ 4,000 rpm, dan masalah junaman kilasan pada versi DOHC asas telah dapat ditangani sepenuhnya. Enjin 1.6L IAFM ini mula digunakan pada kereta Proton Gen-2 M-line dan Proton Persona mulai tahun 2008.

Proton dan Lotus telah mengumumkan model prototaip kereta Proton Gen-2 yang menggunakan enjin Campro hibrid semasa Pertunjukan Kereta Geneva 2007. Sistem enjin hibrid tersebut dikenali sebagai EVE (Cekap, Berdaya Saing, Mesra Alam). Ia menggunakan enjin S4PH sedia ada dan digandingkan dengan motor elektrik 144 V, 30 kW. untuk membolehkan sistem tersebut digunakan pada semua model sedia ada Proton tanpa perlu membangunkan platform baru yang berasingan bagi model kereta hibrid.


Data teknikal sistem hibrid tersebut adalah seperti berikut:-
  • Kuasa kuda maksimum (enjin sahaja): 110 bhp (82 kW) @ 6,000 rpm
  • Kilasan maksimum (enjin sahaja): 148 N-m @ 4,000 rpm
  • Kuasa kuda maksimum (gabungan): 141 bhp (105 kw) @ 5,500 rpm
  • Kilasan maksimum (gabungan): 233 N-m @ 1,500 rpm (dihadkan ke 180 N-m berterusan)
Pada 13 Disember 2008, Pengarah Urusan Proton Datuk Syed Zainal Abidin telah membuat pendedahan bahawa Proton sedang membangunkan versi turbo bagi enjin Campro 1.6 L yang bakal diperkenalkan sekitar tahun 2010-2011. Enjin ini dibangunkan sebagai tindak balas kepada trend pasaran baru di mana enjin bersesaran kecil digunakan tetapi dipasang sistem pernafasan paksaan bagi menghasilkan keluaran kuasa yang setara dengan enjin yang lebih besar, satu konsep yang serupa dengan teknologi pengecas berkembar TSI pada kereta Volkswagen Golf Mk5. Tiada butiran sama ada enjin tersebut bakal dilengkapi dengan sistem pemasaan injap boleh laras CPS atau tidak, tetapi keluaran kuasa dianggarkan sekitar 150 bhp serta kilasan 240 N-m.


Buat masa sekarang, Proton sedang merancang untuk membangunkan enjin bersesaran lebih tinggi (1.8L dan 2.0L) sebagai pelengkap kepada enjin Campro 1.3L dan 1.6L sedia ada serta sedang berbincang dengan beberapa pihak luar bagi membantu pembangunan enjin. Di samping itu, Proton turut merancang untuk menghasilkan versi diesel bagi enjin Campro.
