“…Kelebihan energi listrik yang dihasil dapat digunakan untuk cadangan energi pada pabrik atau dapat dijual dalam bentuk listrik. Menurut Bantacut dan Novitasari (30) , konsumsi listrik minimum rumah tangga adalah 680 kWh per kapita per tahun dengan asumsi setiap rumah terdiri dari 4-5 kapita. Berdasarkan konsumsi listrik per rumah tersebut, maka kelebihan energi listrik setara dengan kebutuhan listrik sekitar 64-96 rumah sepanjang tahun.…”

Processing of palm oil mills effluent (POME) consumes considerable amounts of energy. POME contains organic materials that can be converted into methane gas as an energy source. This study aimed at the development of energy self-sufficiency concept in the POME processing by harvesting the energy contained in the generated biogas. The development of this concept was carried out by analyzing the Chemical Oxygen Demand (COD) balance in POME processing, assessing energy potential, calculating energy requirements, and constructing an energy-independent POME treatment model. The results of this study showed that the electrical energy that can be generated from the processing of POME was 70 kW per hour, while the energy requirement is 39 kWh. The energy potential can meet the energy needs, with an energy surplus of 30 kW per hour. This study explained that the processing of POME can be self-sufficient by degrading organic matter into methane gas using Upflow Anaerobic Sludge Blanket Reactor (UASBR). Keywords: methane, POME, COD model, closed system, electricity, UASBR.ABSTRAKPengolahan limbah cair kelapa sawit menggunakan energi dalam jumlah besar. Limbah cair kelapa sawit mengandung bahan organik yang dapat dikonversi menjadi gas metana sebagai sumber energi. Penelitian ini bertujuan untuk mengembangkan konsep mandiri energi pada pengolahan limbah cair kelapa sawit dengan memanen energi yang terdapat dalam biogas yang terbentuk selama pengolahan limbah cair. Pengembangan konsep ini dilakukan dengan menganalisis keseimbangan COD di dalam limbah cair, mengkaji potensi energi, menghitung kebutuhan energi, dan membangun pengolahan limbah cair kelapa sawit mandiri energi. Hasil studi ini menunjukkan bahwa energi listrik yang dapat dihasilkan dari proses pengolahan limbah cair kelapa sawit adalah sebesar 70 kW per jam, sedangkan kebutuhan energi adalah sebesar 39 kWh. Potensi energi tersebut dapat memenuhi kebutuhan energi, bahkan terdapat surplus energi sebesar 30 kW per jam. Studi ini menjelaskan bahwa pengolahan limbah cair kelapa sawit dapat mandiri energi dengan mendegradasi bahan organik menjadi gas metana menggunakan Upflow Anaerobic Sludge Blanket Reactor (UASBR).Kata kunci: gas metana, limbah cair sawit, model COD, sistem tertutup, listrik, UASBR

Tapioca production consumes large amount of energy to process cassava into tapioca. Most energy used is fossil energy in the form of electricity and diesel oil which availability has declined so that affect the tapioca production process in the very near future. In addition to producing main products, tapioca industry also generates certain amount of by-products such as cassava's peel, stockpile and wastewater that potentially be utilized as an energy source. This research aimed to develop a model of a closed system of energy independent production process of tapioca through reusing the by-product as the energy source. Development of a closed system model was based on the mass balance, assessing energy content of by-products, and build a closed system of tapioca production process. This study used secondary data of processing stages and primary data of material balance from a tapioca industry. The results showed that the achievable yield of tapioca was 32%. The tapioca industry with 1,000 ton of cassava per day has the potential energy of 1,407,714,408 kcal per day derived from cassava stockpiles and cassava peels. This potential energy is able to meet the energy requirements of 99,261 kWh per day for the production process. Therefore, the tapioca industry is potentially being an energy independent industry by optimizing the utilization of by-products.Copy Right, IJAR, 2018,.

Introduction:-The tapioca industry that process cassava always generates by-products in the form of solid waste (stockpile) as much as 16.5%, cassava peel (10-15%), and wastewater (Grace 1997, Kosugi et al. 2008. Mareta (2010) and Winarno et al. (1988) find that the content of carbohydrates in the stockpile is 68% and in the crude fiber is 10%. Mareta (2010) states that the number of stockpiles produced from tapioca production process ranges from 5-10% of the weight of the raw material. Without a proper handling, these by-products can cause environmental pollution. In general, this industry only produces tapioca at 20-30% of the weight of processed cassava (Rahmatul 2013). Stockpile and peel are potential to be used as energy sources to produce heat of the drying process of cassava starch. The tapioca production process will continue to grow to meet the growing demand for both industrial raw materials and food ingredients. Sriroth et al. (2000) calculated the normal needs of electrical energy and thermal energy for producing one kg of tapioca is about 0.320-0.939 MJ and 1.141-2.749 MJ respectively or 25% in the form of electrical energy and 75% in the form of heat and still use energy derived from diesel oil.A closed system is a system that is not related to and not affected by the environment outside the system. In the production process, a closed system can be interpreted as mass and energy balance that is integrated only with the Int . J. Adv. Res. 6(10), 521-532 522 flow of material in the system. Closed systems are not related to mass and energy flows from and to the outsid...

“…In addition, the closed system application will cut the amount of the generated wastes and finally cutting the cost of waste handling. Agroindustry that processing raw material containing energy (carbohydrate, fibre, and oil) is potential to be designed for closed production systems such as crude palm oils (Bantacut and Pasaribu 2015), sugarcane (Bantacut and Novitasari, 2016) and rice (Bantacut and Nurdiansyah, 2017). Development of such systems for cacao processing industry would improve efficiency of the production process and cut generation of the by-product.…”

The objective of this research was to assess energy independent and develop a model of closed system production process of cocoa butter and cocoa powder. Mass balance analysis and potential energy assessment of byproducts were used to develop the closed system of cacao processing industry. The results showed that cacao industry with 4,500 kg of cacao capacity per day has the potential energy of 14,561,290 k cal per day derived from the pod husk and bean shells. This potential energy meets the energy needs for the production process. This study explained that the cacao industry can be developed to be an energy independent industry by using the by-products for energy source.
