Energy needs that are developing at this time are not comparable with the increasing availability of fuel that is running low. Therefore, a study is needed to obtain alternative sources of renewable energy by utilizing biomass waste such as banana peels and so on. In this study, the raw material used was banana peel waste in the industrial area processing bananas that had been taken, and the skin was left to rot and become organic fertilizer. The purpose of this research is to determine whether there is influence of banana skin type to bioethanol content, influence of yeast concentration and fermentation time in bietanol manufacture using banana peel. Based on the research results can be seen that the hights % alcohol content is found in banana peel batu (musa balbisiana)samples with the addition of yeast weight ± 0.0720 gr of 13.6451% then banana peel kepok (musa paradisiaca L) and banana peel raja (musa sapientum) with each % alcohol content of 13.5353% and 12.9953%

Patchouli essential oil that is produced using conventional refining technology often does not meet the requirements for export. Refining using conventional technology requires a relatively long time, the energy required is large and the product quality is low. To improve the quality of patchouli oil and energy savings in this study, the process of making patchouli oil using the Microwave hydro distillation method is used. This process is a combination of the use of microwaves with a distillation system. The material in the flash column section which is made of glass will be penetrated by microwave radiation and will be absorbed by the material. This event will cause heat so that the cell walls in the oil will break and the content in the oil will be free to escape. Based on the results of the study using patchouli plant raw materials, the optimal variation in operating time and microwave power to obtain high yields at 60 minutes power was 0.3301% and the lowest SEC value was at 30 minutes power which was 1.889.92 gr / ml. While the results of the study used patchouli leaf raw materials, the optimal variation in operating time and distillation temperature to obtain high yields at a temperature of 98ËšC minutes 60, namely 0.3301% and the lowest SEC value at a temperature of 98ËšC minutes 30. which is 1,889.92 gr / ml.

Biofuel is an alternative fuel that can be produced with organic resources such as vegetable oil and animal fat. One of the items that can be converted into biofuels is waste cooking oil. Waste cooking oil has a long hydrocarbon chain that allows it to be cracked. Biofuels are produced by catalytic cracking process. Catalytic cracking is a process in which complex hydrocarbon fractions are cracked into smaller, more valuable hydrocarbon. In this process natural zeolite is used by its ability on cracking hydrocarbon fractions. This research aims to get optimum condition of converting waste cooking oil to biofuels and to know the effects of temperature and reaction time on its products produced. The amount of raw materials, type of catalyst and amount of catalyst is preferred as controlled variable in this research, whereas temperature and reaction time is preferred as statistical variable. Biofuels are produced by various temperature such as 280Â°C-320Â°C and reaction time on 30 minutes-150 minutes using natural zeolite catalyst which accelerate the reactions. According to the process that has been done, this research obtained optimum process condition at the highest temperature 320Â°C which reviewed by its yield produced percentage in amount of 9.8147%. Based on various tested parameters including density, viscosity, flash point and GC-MS, biofuels has required the quality standard.

Styrofoam is a thermoplastic polymer that cannot be biodegradable. Styrofoam waste is generally treated using burning method which produce a dangerous gases. Cracking is the right method to solve the problem by converting styrofoam waste into liquid fuel. In this study, the cracking process was carried out by catalytic cracking method using zeolit alam, SiO2.Al2O3 dan Ï’-Al2O3 as a catalyst. The aims of this study are to determine the effect of the number of catalyst and temperature variation on the percentage of yield, physical properties and compound content of liquid fuel. Variabels varied are the number of catalyst 5-25% from total reactants and temperatur variation 300-550 oC.

Coal gasification is the process of converting low rank coal into syngas which can be used as fuel. One of the factors that affect the quality of syngas is the size of coal particles. Meanwhile, to produce clean syngas, the gas from the combustion reactor is flowed through a packed bed absorber filled with marbles to reduce the incompatible particulate gases that are still contained in the syngas. The variations in the size of the coal used in this study are 3-4 cm, 5-6 cm, and 7-8 cm. While the variation of the height of the packing absorber filling used was 9.75 cm, 19.5 cm, 29.25 cm and 39 cm. The composition of the best combustible gas from the variation of coal size and the variation in the filling height of the absorber packing is found in the coal size 3-4 cm, and the packing filling height is 39 cm. With combustible gases (CO, H2 and CH4) produced by 10.9%, 10.5% and 0.9%, the volume of O2 and CO2 is 0.1% and 10.1%, the syngas volume of the absorber output is 2473.47 m3 and the LHV syngas is 6.932 MJ/kg.

Krisis energi yang melanda Indonesia dikarenakan jumlah penduduk semakin meningkat berpengaruh terhadap konsumsi bahan bakar. Salah satu penelitian mengenai pemanfaatan bahan bakar hidrogen dengan proses elektrolisis. Produksi gas hidrogen dari air laut yang mengandung natrium klorida (NaCl) merupakan cara yang dapat dilakukan untuk mendapatkan gas hidrogen. Katalis yang digunakan pada penelitian adalah kalium hidroksida (KOH). Penelitian ini menggunakan proses elektrolisis air dengan memvariasikan tegangan dan jumlah sel elektroda, elekrolit yang digunakan air laut dengan salinitas 5 ppt dan larutan KOH 0,018 M. Variasi tegangan yang digunakan adalah 10, 11, 12, dan 13 Volt, sedangkan variasi jumlah sel elektroda yang digunakan adalah 6, 8, dan 10. Semakin besar tegangan listrik dan jumlah sel elektroda yang digunakan maka semakin besar jumlah poduksi gas yang dihasilkan. Hasil tertinggi yang didapatkan yaitu variasi tegangan 13 Volt dan 10 sel elektroda dengan jumlah produksi gas hidrogen sebanyak 127,211 ml dan efisiensi sebesar 36,38 %.
