TWG III – Energy Efficiency Master Plan TECHNICAL MEETING HOUSE HOLD AND PALM OIL MILL IN NORTH SUMATERA Semarang, 10 th -11 th of July 2011 Universitas Sumatera Utara (USU) TWG III Team
HOUSE HOLD Household is the biggest runner up electricity consumer sector in Indonesia after industrial. In 2003 electricity consumption in household sector reached 35.753,05 MWh, while industry reached 36.497,25 MWh. By assumed the average of electricity requirement growth equal to 7% each year during time range of 30 years, it will cause electricity consumption in household sector increase piercingly out of 21,52 GWh in 2000 become about 444,53 GWh in 2030.
Padang Cermin is a village which is located in Langkat Sub-Province, it is about 35 km from Medan. Padang Cermin has wide area equal to 1948,2 Ha consisting of 837,6 Ha lowland land, 649,7 Ha plantation land and the rest is applied as settlement land and public facility. Most of Padang Cermin people work as farmers, with population 11.997 people that consist of 6122 men and 5875 women. The major people graduated from Senior High School and only a few of them graduated from scholar education. Survey for House Hold Profile of Padang Cermin village, Langkat Sub-Province
A number of people use electricity energy as energy source that is applied as lighting and to for some electronic equipments, but there are also some households which still use energy source from oil fuel as kerosene applied as lightings and cooking. Peoples houses taken as object of collecting data is distinguished based on level of attached electricity usage, that is 450 VA, 900 VA and 1300 VA. Survey is done to see electronic equipment applied and calculate capacity of each electricity equipment and usage duration.

Survey for Palm Oil Mill Palm Oil Factory at PTPN IV Mayang Bosar Maligas Palm Factory Mayang Bosar Maligas is located in Perdagangan, Sub- Province Simalungun,North Sumatera, it is about150 km from Medan.. Palm Factory Mayang Bosar Maligas was built 1951 with mill process of 40 ton/hour. For steam requirement of electricity power, we need a boiler as the energy source. The used boiler is a waste tube boiler. Boiler has function to change water into high pressured heat vapor which then be used to turn around turbine blade integrated with electric generator to produce electricity.
Palm Oil Mill Specification at PTPN IV Mayang Bosar Maligas
Potential of liquid waste (POME) Potential of liquid waste (POME) Besides solid waste, liquid waste also has big enough capacity in palm industry. Liquid waste especially produced during clarification processing, deposition and centrifugation which is done during CPO clarification processing. According to the central of palm research (1992-1993) the capacity of liquid waste1-1,3m3/ton bunch of fresh fruit or 2- 3 ton liquid waste/ton oil.
POME Calculation Palm Oil Mills in North Sumatera, have capacity around 30 Ton FFB/hour to 60 ton FFB/hour. Palm Oil Mills process during production will produce Palm Oil Mill Effluent (POME). Every each ton FFB produced 65% m 3 of POME If one Palm Oil Mill produce 40 ton FFB per hour then it will have 26 m 3 /hour POME POME that produced from the Palm Oil Mill will process at anaerobic pool to have an Biogas. A Chemical Oxigen Demand (COD) is needed at some value to produce Gas from POME.
From the laboratorium data, COD normally is between 35 – 45 kg/m 3 With COD 40kg/ m 3 we can calculate the production of BIOGAS. For examples for 26 m 3 of POME will produce 1040 kg COD. Every each kg of COD it will produce 35% of Biogas, with 1040 kg COD it can have 364 m 3 Biogas. With known Low Heating Value (LHV) of Biogas, and assuming 35% efficeincy, the power from generated power can be calculated. And the generator input power is : 364 m 3 biogas x 35,880 MJ/m 3 = 3,63 MW(t)h (MW(t)h = Mega Watt thermal hour) Power generated is 3,63 MW(t)h x 0,35 = 1,3 MW(e)h POME Calculation
