Indonesia has a lot of natural resources which is deficient to fulfill the energy demand of consumers, particularly fuel. Therefore, the government keeps on promoting the search for alternative energy. One of these is hydrogen. Hydrogen is an environmental friendly product that does not produce carbon emissions. In the formation of hydrogen we can use carbohydrate-rich waste as a raw material and by using fermentation process. However, it is still limited research only. So this encourage us to design biohydrogen plant from palm oil mill effluent (POME) with the conditions of thermophilic anaerobic fermentation in order to accomplish the needs of consumers and contribute in developing clean technologies. For the production capacity of 495.1694 tons / year, the total investment required to build a factory of biohydrogen in Indonesia is Rp. 507,190,573,523, - with a total production cost of Rp. 354,636,600,139, -. Parameter feasibility of the production capacity of 495.1694 tons / year is the total product sales of Rp 174,261,989.701, - and net income 180,030,185,327, -. Profit Margin (PM) 41.9% Break Even Point (BEP) 45.24%, Return on Investment (ROI) 35.5%, Pay Out Time (POT) 2.82 years, Return of Network (RON) 59.16%, Internal Rate of Return (IRR) 53.52 %.

The purpose of this research is to determine the effect of Fe level as trace metal on the quantity of biogas produced from the fermentation of palm oil mill effluent (POME). Materials used in this study included POME from one of the palm oil factories belong to PTPN IV, hydrochloric acid, sodium bicarbonate, and trace metal. Observed variables were volume of biogas, concentration of Fe in fermentor, rate of degradation total solid (TS) and volatile solid (VS), and CO2at Hydraulic Retention Time (HRT) 6 days. Before HRT of 6 days reached, initial trace metal composition of Fe added were 25.2 mg / L, Co 0.42 mg / L and Ni 0.49 mg/ L. After that, composition of trace metal were consisted only Co and Ni. The results of this study showed that Fe as a trace metal did not affect the production or quantity of biogas and concentration Fe on level > 330 mg/L decreased the value of CH4, total solid (TS) and volatil solid (VS). Thus, Fe in the trace metal is no longer required if there is a high content of Fe in POME because it can be toxic for microorganism in the fermentation of biogas.

Palm oil mill effluent (POME) production in Indonesia is estimated around 28.7 million ton/year. Generally, POME treatment is done conventionally by using facultative ponds. Aside from the vast usage of land and operational cost, this system also emits greenhouse gases. Eventhough, POME is a potential raw resource in producing biogas. Previous researches were done with anaerobic process to produce biogas, but the waste produced still haven’t met the standard quality control requirements. The total suspended solid (TSS) contained in the waste produced from the anaerobic process is still around 400 mg/L, which is the reason why aerobic process is still necessary to drop the number of TSS contained by using effective microorganism. From the result, a 10 day HRT aerobic process can reduce the number of TSS to around 200 mg/L.

Bioethanol is ethanol, which made from starch, glucose, or cellulose of plants. In this research, it has been made from cellulose of sugarcane baggase. This research was conducted to study about the effect of pH, yeast type and the duration of fermentation to yield’s ethanol. The main processes in this research were thermal hydrolysis by liquid hot water (LHW) method, fermentation by using Saccharomyces cerevisiae and purification by vacuum distillation. The variables in this research were pH 4; 4,5; and 5; baker’s yeast and fermented glutinous cassava; and the duration of fermentation were 2, 4, 6, 8 and 10 days. Based on the analysis of the yield, the volume of bioethanol is 23 mL with 0,95 g/ml density and 161,59 kkal/kg heat value as the best yield, under the condition of pH 5 and 4 days of the duration of fermentation using baker’s yeast.

Rice husk is material waste that is usually just burned. However, this practice is causing air pollution problems. One effort to help overcome the problem of agricultural waste is recycling technique with an emphasis on the process of composting. Many efforts can be made to speed the composting process. The treatment was performed by the addition of slurry at the beginning of composting process with the addition of as much as 1, 2,and 3 liters and the addition of slurry during composting process by adding 0,5;1; and 1,5liters of slurry every 3 days once. At each treatment was added 1 kg of fine compost. The condition which almost meets quality compost by SNI 19-7030-2004 and most precocious and decomposesis the compost with the addition of as much as 1, 5 liters every 3 days where the temperature is 32,8 oC obtained, the water level is 35,1,99 %, the ratio of C / N is 7.58 and pH is 9,59. This thing indicates that the slurry from biogas fermentor can accelerate the maturity of compost making so that it is more easily broken down or decomposed.

LCPKS further processing is usually done by using activated sludge system is implemented in an open pond.This system requires a large enough dissolved oxygen so that if the system would lead to poor aeration then the HRT will be great. In addition to the spread of foul smell due to the system being used is open. This study aims to produce a prototype bioreactor that can be used to replace the above processing system. Bioreactor tank made of transparent plastic tube that comes by baffles and stirrer are made of stainless steel. In addition, the bioreactor is also equipped with a motor stirrer, aeration systems, and deodorizing unit. The resulting prototype has 11.078 cm high and 21.4 cm diameter, 9.2-liter operating volume, and fluid and baffle height is 24.5 cm. Bioreactor equipped with two stirrer blade that is horizontal turbine disc type at 7.13 cm of the tank bottom and paddle 4-rowing at 12.84 cm above the first blade. Bioreactor prototype has passed the leakage testand if the air flowing in at a constant velocity 0.5 m/s then the value of gasholdup (ε) is 0.02. Used this prototype for further processing LCPKS cause COD value of waste fell from 4,482 mg/l to 3,096 mg/l for 30 days long processed.

Composting process of rice husk (Oryza sativa) by adding various activators have been carried out in LPPM Training Center, University of Sumatera Utara. The purpose of this study was to compare the effect of variation of slurry and bacteria (yeast and EM4) on rice husk composting results. The parameters observed were changes in temperature, water content, C/N ratio, and pH. At the end of the composting results showed that the addition of slurry, yeast and EM4 can lower the temperature and C / N ratio, and with the addition of yeast and 2 liters of slurry can speed up the process of decomposition of compost.

This research aims to determine the composting technique for Empty Fruit Bunch (EFB) and to collect the degration data during composting of EFB in order to get a high quality compost. The composting process was started with cutting the EFB into four parts before it was put into composter and then followed by the addition of Activated Liquid Organic Fertilizer (ALOF) until the optimum moisture content (MC) of 55-65 % was reached. The parameters of temperature, MC, pH, C/N ratio, Electrical Conductivity (EC), Water Holding Capacity (WHC), Bacterial Count (BC) and the quality of compost were analyzed through the process. The results of this research showed that the compost were well done in about 10 days and the best degradation during the 40 days of composting was obtained in which value of MC, pH, C, N, C/N ratio, EC, WHC and BC were 79,14%; 8,1; 25,16%;1,20%; 20,97; 4,725 dS/m; 60% and 107 CFU/ml, respectively.
