Abstract

Solid Waste Oil Palm Empty Fruit Bunches have high nutrients, which significantly determine oil palm growth rate and production. Each nutrient has its role and can show specific symptoms in plants if their availability in the soil is very lacking. Dry oil palm land and the difficulty of procuring chemical fertilizers for the community that owns oil palm plantations in Simardona Village are expected to be overcome by the use of OPEFB. Utilization of Oil Palm Empty Bunches as Mulch was done manually in 4 research scenarios. Scenario 1 uses 2 kg of chemical fertilizers plus 250 kg of OPEFB, scenario 2 uses 2 kg of chemical fertilizers plus 300 kg of OPEFB, scenario 3 uses 2 kg of chemical fertilizers plus 350 kg of OPEFB, and scenario 4 uses 2 kg of chemical fertilizers plus 400 kg of OPEFB.The results obtained are that the humidity or moisture has increased from a value of 1 to 4. Therefore, it can be seen that the effect obtained from the use of more OPEFB makes the humidity higher. The calculation of the total cost of using OPOPEFB as mulch is obtained from the sum of the price of chemical fertilizers, the price of OPOPEFB, and workers' wages. The total cost after utilization of TKKS is IDR854,000.00. The total cost before using TKKS was IDR441,600,000. The difference in costs before and after the utilization of TKKS is IDR412,400.00, an increase in costs of 48%. The cost of using TKKS is higher than before using TKKS. The total harvest obtained before the use of OPEFB is 2,000 kg or IDR4,900,000. Meanwhile, after using OPEFB, the total yield obtained was 2,700 kg or IDR6,615,000. Production income increased by 26%.

Abstract

Aceh Tamiang is the province o f Aceh. The use of electrical energy is still not resolved in this case because of the lack of appropriate policies that can be taken because there is still no research how the amount of electrical energy consumption in Aceh Tamiang. the research method used is a model based approach to End Use of data population and households, the data GDP at constant prices, and consumption of electrical energy. All data is sourced from related agencies such as Bappeda Aceh Tamiang Data PLN Kuala Simpang branch. Forecasting electric energy consumption in Aceh on five sectors is the year 2013 was 48.8 GWh, while, in 2030 total energy consumption reached 76.5 GWh, this is an increase of 63.7 percent. The household sector accounted for the largest increase in consumption compared with other sectors for each year.

Abstract

Pemanfaatan pembangkit listrik tenaga surya (PLTS) untuk memenuhi kebutuhan listrik internal pembangkit termal dapat menjadi salah satu alternatif dalam mengurangi penggunaan energi berbasis batubara. Penelitian ini bertujuan mengevaluasi kelayakan teknis dan ekonomi PLTS ground-mounted dengan sistem zero export untuk memasok sebagian house load PLTU Paiton Unit 7 dan 8. Sistem dirancang dengan kapasitas 5.002,8 kWp pada sisi DC dan 4 MW pada sisi AC menggunakan 9.096 modul fotovoltaik berkapasitas 550 Wp dan 16 inverter berkapasitas 250 kW. Analisis teknis dilakukan menggunakan PVsyst, sedangkan analisis ekonomi menggunakan indikator LCOE, NPV, IRR, PI, PP, dan ROI. Hasil simulasi menunjukkan produksi energi sebesar 8.281,1 MWh/tahun, specific yield 1.655 kWh/kWp/tahun, dan performance ratio 82,62%. Skenario P90 sebesar 7.815 MWh/tahun digunakan sebagai dasar analisis ekonomi. Pada kondisi dasar dengan CAPEX Rp52,72 miliar dan tingkat diskonto 9%, diperoleh LCOE Rp913,08/kWh, NPV ?Rp13,57 miliar, IRR 4,34%, dan PI 0,74, sehingga proyek belum memenuhi kriteria kelayakan finansial. Analisis sensitivitas menunjukkan bahwa CAPEX merupakan parameter yang paling berpengaruh terhadap kelayakan. Kombinasi penurunan CAPEX 15% dan kenaikan harga batubara 10% meningkatkan NPV menjadi ?Rp231,37 juta, IRR 8,91%, dan PI 0,99. Analisis break-even menunjukkan bahwa proyek mencapai NPV nol pada CAPEX Rp40,86 miliar atau 22,49% lebih rendah dari kondisi dasar, dengan harga batubara tetap USD70/ton dan produksi energi P90. Hasil penelitian menunjukkan bahwa sistem layak secara teknis, sedangkan kelayakan finansial sangat dipengaruhi oleh kemampuan mengoptimalkan biaya investasi tanpa menurunkan spesifikasi dan kinerja teknis system.
