2. Prof. Ir. R.M. Sedyatmo 

the inventor of the chicken claw foundation

The man who graduated from the Bandung Institute of Technology (ITB) in 1934 invented an infrastructure architectural system known as the chicken claw foundation. One of the places that uses Prof.'s chicken claw foundation. Ir. R.M. Sedyatmo is the runway of Soekarno Hatta airport.

Sedyatmo was born in Karangpandan village, Central Java on Sunday Kliwon on October 24, 1909 as the third son of Raden Mas Panji Hatmo Hudoyo (grandson of Mangkunegoro III-Surakarta) with R. Ayu. Sarsani Mangunkusumo. Sedyatmo's first name is Raden Mas Sarwanto. When he was a few months old, he was ill long enough that he had to change his name. His parents then gave him the new name R.M Sedyatmo. The name Sedyatmo is taken from the words Sedia and Atmo which means ready, able or willing and Atmo which means child. Through this new name, his parents hope that Sedyatmo will become a good and useful child for the community, nation and country. A prayer that a few years later came true.

Sedyatmo was the originator of the idea of ​​the Chicken Claw construction foundation system being widely applied as a foundation solution on soft land. The Chicken Claw construction was introduced by Sedyatmo in 1962 and has been patented both nationally and internationally. This chicken claw foundation system has also been known in many countries, and has even received international patent recognition in 11 (eleven) countries, namely: Indonesia, East Germany, England, France, Italy, Belgium, Canada, the United States, West Germany, the Netherlands and Denmark. . Chicken claw foundation is composed of thin reinforced concrete slabs supported by reinforced concrete buis-buis vertically mounted and united monolithically with concrete slabs at a distance of 200-250cm. The thickness of the concrete plate ranges from 10-20cm, while the reinforced concrete buis pipe has a diameter of 120cm with a thickness ranging from 8cm and a length of 150-250cm. Buis-buis concrete is useful for slab stiffeners. In supporting the load of the building, the concrete buis slab and the soil enclosed in the foundation work together to create a composite system which in its overall operation is identical to the raft foundation.

The mechanism in carrying the load is explained as follows: when a point load is applied to the plate, the load causes the plate to sag. This deflection causes the claws to rotate. The results of observations on the model show that the largest claw rotation is in the claws located near the load. The rotation of the claw mobilizes the lateral earth pressure behind the claw and is a moment against plate deflection. Thus, how to reduce plate deflection, the greater the moment against the claw against the deflection, the greater the deflection reduction. The opposing claw moment is influenced by the claw dimensions and the density condition (shear strength) of the soil around the claw, namely the longer (and also the width) of the claw, the greater the opposing moment against plate deflection that can be obtained.

Many buildings have used this system, including: hundreds of high-voltage PLN towers, airplane hangars with a stretch of 64m in Jakarta and Surabaya, between runways and taxiways and the apron of Soekarno-Hatta Airport in Jakarta, Pluit-Cengkareng access road, fertilizer factories in Surabaya. , swimming pools and stands in Samarinda as well as hundreds of high-rise buildings in various cities in Indonesia.

3. Yogi Ahmad Erlangga 

mathematical formula in petroleum

The man who had studied at Delft University of Technology, the Netherlands, is listed as the youngest doctor of Mathematics. He found a formula to solve various oil problems and his ability to attract the attention of the world's oil company, namely Shell.

Dr. Yogi Ahmad Erlangga, 1993 ITB Aviation Engineering alumnus, was awarded the Achmad Bakrie award for the category of outstanding young scientists. The Achmad Bakrie X award was given by the Freedom Institute on Sunday (12/08/12). Yogi, who is a lecturer at the ITB Aviation Engineering Study Program, received this title for his achievement in solving the Helmholtz equation using numerical mathematics quickly (robust).

The research, which was carried out as his PhD research, used the "Helmholtz Equation" method. This method is a way to interpret acoustic wave measurement data. The fruit of his research can accelerate the processing of seismic data in surveys of oil reserves. It is not surprising that an international oil company is enthusiastic about providing funds to complete this research.

Yogi successfully defended his thesis in the auditorium of Delft University of Technology (DUT), Netherlands before the examiners in December 2005. From his findings, the Helmholtz equation used in processing seismic data is a hundred times faster. This is a breath of fresh air for oil companies because this method is proven to be better and faster than what is commonly used.

Obtaining a bachelor's degree in engineering at the Aeronautics and Astronautics Study Program ITB in 1998, Yogi continued his studies at DUT, the Netherlands. He obtained master's and doctoral degrees in applied mathematics from the same university.

Yogi, who had attended a post-doctoral program in Germany, was recorded as an assistant professor in mathematics at Alfaisal University, Saudi Arabia. While being an assistant professor, Yogi did a lot of research in the fields of linear algebra and matrix analysis.

This great discovery had become a byword among world scientists. Yogi's supervising professor, Dr. Vees Vuik said he was proud of the success of his research. "Based on the responses we have received from industry and foreign universities, we believe that this work has solved a problem that has been going on for thirty years," said Vuik in a DUT press release.

The Achmad Bakrie award was given by the Freedom Institute which was founded by Aburizal Bakrie. In the opening ceremony, Aburizal explained the reasons for giving the award. "These figures have given dedication, dharma filial piety, and positive contributions in their respective fields of knowledge and service," said Aburizal Bakrie.

The research conducted by Yogi turned out to be fruitful not only in the petroleum industry but also in other industries. Since the Helmholtz equation describes wave behavior in general, this discovery also has implications for industries that use wave properties such as the radar industry for aviation as well as laser applications. In addition, it turns out that the results of this research are also capable of developing the blu-ray disc industry because it can increase data storage capacity.

4. Randall Hartolaksono 

anti-hot and anti-fire fuel

At first, the idea he sparked was underestimated by many people. However, this man who graduated from the University of London never gave up and tried to realize his idea of ​​creating an anti-heat and anti-fire fuel. In the end, this man was appreciated and recognized by the world's automotive companies, such as Petronas and Ford.

Randall Hartolaksono is a man who graduated from the University of London. He has succeeded in finding materials that are widely used by the world's automotive companies. Randall succeeded in creating a fire-resistant and heat-resistant material from cassava skin. Now Randall's work is used in several world products such as Ford, Petronas and so on.

Randall Hartolaksono, BSc. MSc., served as Managing Director of several companies, namely PT. Hart Industries Limited (UK), London, England, since 1990; PT. Hartindo Chemicatama Industri (started in 1992): Newstar Holdings Singapore (from 1995); and Newstar Chemicals Malaysia (since 2000). Randall received formal education at Pangudi Luhur High School-Jakarta, Advance Level in Science (Hounslow Borough College-London UK), BSc. as well as MSc. in Mechanical Engineering (Queen Mary College-London University, UK).

Apart from that, he has also attended several non-formal education courses, starting from Chemistry Courses, Malay Language, to Fire Fighting Education. For the latter, he even has 2 diplomas, namely and Fire Service College and Washington Hall College, which are the largest firefighting educational institutions in the world.

His career journey began in 1983, working as a Production Engineer for Mobil Oil Indonesia, which he served until 1985. After that, he worked for Petroleum Engineer Petroleum, UK (1986-1990), before finally establishing the companies he has managed until now. .

After graduating from high school, Randall continued his education at the Faculty of Dentistry, Trisakti University, Jakarta. But then, when he was 18, he was sent to study in London. There, in accordance with his passion for mechanics, he pursued the field of Mechanical Engineer, earning a BSc degree. and MSc.

Since discovering chemicals that can extinguish and prevent fires in 1979, Randall can be said to have entered the industrial world, specifically in the field of Fire Safety. Where, after that he struggled to compile a formula, until he finally succeeded in creating a new chemical to extinguish and prevent fire.

In the field of Professional Organizations, his name is registered in the membership of various International Professional Associations, including the Institute of Mechanical Engineers (IME-UK), National Fire Prevention Association (NFPA -USA), Fire Prevention Association (FPA-UK), Malaysian Fire Protection Association (MFPA – Malaysia) and the Institute of Fire Engineers (IFE-UK).

In the hands of Randall Hartolaksono, cassava skin which has received less attention can be turned into a world class fire retardant material. The revolutionary findings of Arek Suroboyo, who was born on March 16, 1956, happened by accident. He discovered this anti-fire material while studying at the Mechanical Engineering Department at the University of London (he entered in 1977, because his lecturers found it difficult to spell Hartolaksono, so his name was often called Hart). There he was researching the essence of cassava peel to be used as a lubricant for robotic hinges, when he accidentally spilled the substance over a flame. It turned out the fire was out. Randall was amazed. Under the guidance of Professor Evans, he researched the efficacy of cassava skin.

After further investigation, Randal found that cassava extract was proven to break the chemical chain reaction in the fire process. "The active substance can prevent the energy jump of electrons past the critical point in the outer layer of the atom during combustion," he said.

Randall dubbed his theory the "free radical". This theory was rejected by British experts at an annual meeting at Edinburgh University, Scotland, 1982. Randall's theory was accepted after five years of laboratory trials. "They call it the chemical chain breaking theory," he said.

In further research, active substances from cassava peels, such as tripotasium citrate, can be developed into various anti-fire products. Some are like paint, applied to wood, making it fire resistant for 200 years! There is also a spray tube that is inserted to extinguish the flame.

Now Randall's three products have received standard test certificates from several countries, such as the United States, Britain and Australia. Its products can penetrate many elite places, such as England's Buckingham Palace. Malaysian companies such as Petronas, Proton and Telecom are replacing halon products with environmentally friendly Randall products. Some star hotels have started to be infiltrated by Randall's products.

The holder of permanent residence status in England and Singapore has built a business empire called Hartindo Chemicatama Industri. Apart from Jakarta and Surabaya, Randall also built assembly plants in Malaysia, Singapore, Taiwan, England and Thailand.
