Abstract

Abstract–Issues about the energy crisis and clean energy in the environment become an important issue. Energy that meets the above properties is solar energy. Utilization is highly dependent on climate and weather conditions in accordance with the geographical location of the place. Optimization of energy absorption needs to be done and this is usually done by conditioning or manipulating some parameters so that the level of energy absorption is more effective and efficient.This research is an expriment research by optimizing the absorption of heat energy to heat water according to climate and weather conditions in Pontianak, West Kalimantan. The variable to be conditioned or arranged so that the maximum heat transfer rate is the flow rate of the water fluid to be heated.The experimental results show that the water flow rate of 2450 ccm DHW Loop side for SHW has a temperature difference value on the exit side of the heat exchanger which is smaller than the others. This shows that the more effective the release and absorption of heat made by the fluid in the heat exchanger. Keywords– Solar energy, Solar Water Heater (SHW), fluid flow rate, heat transfer rate

Abstract

Abstract– Meningkatnya penggunaan beban non-linier pada pada laboratorium dapat menyebabkan munculnya harmonisa yang dapat mengganggu sistem distribusi energi listrik. Dengan melakukan pengukuran secara langsung menggunakan Fluke 43B Power Quality Analyzer pada beberapa peralatan laboratorium, maka dapat diketahui bahwa harmonisa dapat memperburuk kualitas daya yang dapat meningkatkan rugi-rugi pada sistem distribusi energi listrik, sehingga terjadinya pemborosan energi. Dalam penelitian ini pengukuran dilakukan pada beberapa jenis peralatan laboratorium seperti osiloskop, komputer, catu daya DC, dan sebagainya. Setelah diteliti, maka beban lampu hemat energi (LHE) dan komputer (PC) merupakan beban listrik dengan kandungan harmonisa tertinggi yaitu sebesar 81,1 % dan 72,2 %. Dengan memperkecil nilai kandungan arus harmonisa yang disebabkan oleh beban non-linier maka akan menyebabkan nilai THDi menjadi lebih kecil sehingga rugi-rugi pemakaian energi listrik dapat dihindari. Keywords-  harmonisa, THDi, rugi-rugi

Abstract

Abstract– Currently the main products of oil palm are mainly used as the producer of vegetable oil. The waste originally becoming problems for environment can be used as renewable energy. One of the solutions is by making use of oil palm waste as the fuel of Steam Power Plant. The objective of this thesis is to identify the number of production of fresh fruit branch and waste generated as well as to calculate the potential energy of oil palm waste as the fuel of Biomass Steam Power Plant. The solid wastes of oil palm studied were fibre and shell. Every ton of fresh fruit branch produced 13% fibre with the energy of 2,637 kCal/kg and 6.5% shell with the energy of 4,105 kCal/kg. The area of oil palm plantations that have already had plantation business permit in Landak District is 451,903.06 Ha. The research results show that the potential fibre and shell that can produced by 5 oil palm factories in Landak District, with the production capacity of 225 Ton TBS/hour during the last 6 years until 2016 reached 344,490,729 tons. The potential energy produced is 1,240,590,477 MWh. Based on the Regulation of the Minister of Energy and Mineral Resources No. 12 of 2017 on the Use of Renewable Energy for the Provision of Power, the basic cost of power plant for West Kalimantan Area is 1,406.75. Therefore, the remaining energy ready to use or sell (excess power) after reduced by the factory use is 1,186,885,214 MWh, and the estimated revenue from power sale generated by 5 units of oil palm factories is Rp 1,669,650,774,795. From five samples of oil palm factories, it can be used to estimate the potential energy from oil palm waste in the entire area of Landak District, based on the plant area that can produce the yield and not produce the yield yet. Therefore, the oil palm area of 113,800.59 Ha, it can be produced estimated potential energy of 2,033,268,169 kWh/year and estimated revenue of Rp 2,860,299,996,037,-. The potential energy from oil palm waste will increase year by year along with the increasing procution capacity, oil palm plantation area and increasing oil palm factory construction so that it can increase energy diversification in Landak District.
