Abstract
Increasing demand for Crude Palm Oil (CPO) as the vegetable oil was causing the industry to cultivate palm oil increased, so that the energy required to produce CPO also increased. The purpose of this study is to identify the type, source and calculate the amount of energy needs, calculate the level of efficiency and energy savings opportunities. Stages of the research are initial energy analysis, a detailed energy, and energy analysis in processing systems. Based on the research results, to produce each kg of CPO processing capacity of 60 ton TBS / hour with a recovery rate of 20.59% of primary energy needs of 16.200679 MJ / kg. Real boiler efficiency of 45.69%, the real efficiency of the turbine was 94, 86%. Turbine efficiency to generate electrical energy by 1.09%, the technical efficiency of 66.80% turbines, diesel generators technical efficiency of 47.25%, the technical efficiency of electric motors by 59.37%. The total efficiency of electricity use by 4,75%, the efficiency of diesel estate of 1.379% and the efficiency of the use of steam at 93.77%. Energy can be saved by 0.0442 MJ / kg with a description of human powered energy of 0.0004316 MJ / kg, energy electrical energy by .04372 MJ / kg. While energy can be stored on the excess energy to fuel biomass boiler was 1.45 MJ / kg

Prosedur operasional standar yang telah ditetapkan harus terus ditegakkan. ditingkatkan Pemeliharaan, perawatan sarana pendukung serta kebersihan pabrik perlu ditingkatkan, sehingga proses pengolahan dapat berjalan efektif dan efisien
Summary
Metode pengambilan data dengan dua cara yaitu, pengamblan data primer yang melakukan pengamatan langsung kebutuhan energi berupa input energi biomassa, energi minyak diesel (solar), energi manusia, energi listrik dan energi uap pada setiap tahapan pengolahan dan sarana pendukung. Tahapan penelitian yang dilakukan adalah penentuan batasan sistem, analisis energi awal, analisis energi rinci, analisis energi pada sistem produksi. Analisis data yang digunakan adalah analisis proses dalam skala mikro. Data yang diperoleh dimasukkan ke dalam persamaan yang telah ditentukan, sehingga diperoleh nilai kebutuhan energi pada tiap tahapan proses produksi. Analisis selanjutnya yaitu melihat efisiensi alat dan proses pada tiap tahapan produksi, sehingga dapat diketahui besarnya energi yang dapat dihemat. El = Energi listrik (MJ/kg) P = Daya motor/mesisn terukur (kw) T = Waktu pemakaian alat (jam) Ƞ = Efisiensi teknis alat J = Jumlah produksi CPO (kg/hari).
