Pendaurulangan Pelumas Bekas dengan Pemanfaatan Bentonit dan Batubara. Azka Hanif dan Ivan F. ISPO 2013.

Bentonit adalah salah satu produk bahan galian mineral dengan berbagai kegunaan dalami ndustri, terutama sebagai penjernih atau pemucat warna, mampu meningkatkan kejernihan minyak pelumas hasil proses daur ulang dengan batubara. Proses penjernihan dilakukan dengan menambahkan sejumlah bentonit pada pelumas yang sebelumnya telah dipanaskan dan ditambah surfaktan alkilbenzensulfonat yang berfungsi membentuk system emulsi air-minyak.

Berat bentonit yang ditambahkanadalah 6 g sedangkan konsentrasi alkilbenzensulfonat yang ditambahkan adalah 17,5%. Nilai absorban yang diperoleh adalah 0,295. Nilaiabsorban ini sudah sesuai dengan kisaran nilai absorban standar base oil.

Money is used generally by the public as a payment tool. The overused  money can be damaged so it is unfit for use. Therefore, every central banks around  the country  replaces the damaged money regularly and pile them as trash. Hence, an environmental issue is generated; an excessive piling of money waste.

On the other hand, the use of coal and wood for industrial purposes also causes its own environmental problems. Coal which has been relied upon as a source of energy for the manufacturing process remains waste that is difficult to deal with from  its combustion. While the use of firewood for large industrial demands a large amount of natural wood.

The solution to these problems is to utilize waste paper money as an alternative fuel. However, the problem  is, (1) What is the best way to produce briquettes of waste of  money? (2) Can the effectiveness of  briquette of  money waste compete with coal and firewood? (3) Will the price of money waste briquettes be affordable and can be generally used?

We do our research by testing the proxymate analysis and ultimate analysis of each briquette we make, comparing money waste briqquete with firewood and coal by doing combustion  test, and doing a price comparison analysis.

According to our research, it is found that the best way to produce briquettes of money waste is by using a pressing machine and by using a mixture of PVCa glue. Because the result is more practical and  neater. Compared with coal and firewood, waste money briquettes is up to par. Besides being more environmentally friendly because the ash level is low (4.74%), use of money waste briquettes for industrial use also can save as much as 20% cost compared to firewood and 60% cost compared to coal

Over time, the growth of world population is rapidly increasing, one of them is in Indonesia. At the same time, growth in the industrial sector was growing rapidly is automatically participate because it is influenced by the growing human needs in various fields. In the industrial sector, for example in the automotive repair shop or in other industries that use machine as a tool works, it takes a lubricant (oil) so that the engine can run well and hassle free. The use of oil in the community, too, increases with increasing community needs for vehicles from year to year. Then, the problem is how will the waste oil that has been used can be processed after use, where waste oil is included in the B3 waste (Hazardous and Toxic Materials).

            Today reserves of petroleum energy sources which is the base material for the manufacture of lubricating oil feedstock decreases. It has led to develop the processing technology of petroleum products in good way. We found one solution to overcome this problem is to recycle used oil using waste banana peel to produce lubricating base (base oil).

            The purpose of this project is to be able to recycle the used oil using a medium that is cheap and easily obtained in the form of waste banana peel. Waste banana peel that we normally throw in, in this way chemical content in it will be used to absorb pollutants and stabilize the color of the used oil. Absorbace relative for this experiment is 0.013.
