Abstract

Palm Oil Factory Energy consists of steam and electricity. To increase the performance, energy will to beaudited. Electrical measurements are carried out at the power house, panels at each station and some electricmotors. Measurement in the main panel uses a power quality analyzer that can measure power, power factor,harmonics, unbalance and other electrical parameters. For measurement of mechanical equipment with steamenergy such as boilers and turbines using temperature measuring devices with infrared thermal imaging toolsFLIR brand. The quality of electric power with a total harmonic of 5.12% and individual harmonics of 2.78%.Voltage and current unbalance are 0.09% and 0.15%. Voltage drop is equal to 3 volts. The use of electricityutilities is 22.81 kW / ton FFB. The factory has cos phi of 0.84 but requires automatic power factor correction.The efficiency of boilers is 64.19% with the biggest losses being dry flue gas of 20.19% and oyher boiler of67.82% with the biggest losses being dry flue gas of 16.45%.

Abstract

Porang (Amorphophallus Muelleri Blume) contain quite high glucomannan (15-64% dry basis). Porang are used as raw materials for food and industry since 1,000 years ago in Japan and China. The high content of glucomannan in porang makes this plant much sought after, especially in the food and health industries. Porang plants need to be researched so that they can be intercropped for oil palm and rubber. Analysis of drainage, texture, coarse material, soil depth, peat thickness and peat maturity was carried out using the borring method and field soil physics tests were carried out. Observation of the level of slope and erosion hazard using a clinometer. And for observations of puddles, surface rocks and rock outcrops with a percentage (%) visualization of the rock volume in the field. Meanwhile, the value of CEC, base saturation, and organic C was obtained from soil analysis resulting from borring sampling in the laboratory. Based on observations and analysis, gardens A, B and C were obtained according to the suitability of the S3 land. To increase the added value, porang is produced in the form of chips. The factory construction investment requires working capital funds and an investment of IDR 3,176,308,600. Investment analysis with tuber seeds showed a positive NPV of Rp. 14,021,379,827.63, IRR >20% and a payback period of 2 years, while the construction of a factory with frog seed cultivation showed a positive NPV of Rp. 3,976,301,962.35, IRR >20%. and Payback Period 4 years 2 months. Based on the two alternatives above, it can be concluded that the investment in building a factory in A plantation by cultivating tuber seeds is better than frog seeds which are shown to have better NPV and Payback Period values
