Abstract

Indonesia is a country that has quite large resources and reserves (3.25%) of the world's coal reserves. Indonesia's coal production in 2022 will reach 687 million tonnes to meet domestic and foreign (export) demand. Indonesia's coal production from year to year has an increasing trend. The existence of this upward trend can result in a decrease in the number of existing coal reserves. This study aims to predict the peak of coal production by estimating the age of the existing reserves. The data used is annual data from 1996 to 2021. The coal reserves used as a basis for consideration are 36,278.85 million tons. The methods used to forecast coal peak production and reserve age are the Hubbert, logistics, and Gomperzt models. The results obtained explain that the peak of coal production occurred in 2018 amounting to 0.539 billion tons with a coal reserve until 2081. For the logistic and Gomperzt models, the peak of coal production occurred in 2033 amounting to 1.345 billion tons and 0.7604 billion tons. Meanwhile, the reserve ages of the two models until 2080 and 2120.

Abstract

Listrik menjadi kebutuhan utama dalam kehidupan masyarakat modern saat ini. Sebanyak 88% sumber energi listrik berasal dari sumber energi tak terbarukan, sedangkan hanya 12% energi listrik berasal dari sumber energi baru terbarukan. Penggunaan sumber energi tak terbarukan memberikan dampak buruk yang besar terhadap lingkungan dan kesehatan. Untuk menekan dampak emisi karbon dioksida, penggunaan sumber daya tak terbarukan perlu diminimalkan, dan diganti dengan teknologi yang mampu mengubah sumber energi terbarukan menjadi energi listrik. Merujuk pada Peraturan Presiden No. 112 Tahun 2022 dan RUPTL PT.PLN (Persero) tahun 2021–2030 tentang percepatan penggunaan energi terbarukan sebagai sumber daya penghasil energi listrik, peneliti membuat penelitian ini yang bertujuan merencanakan PLTS Off-Grid bagi Kantor Kelurahan Amban, Kabupaten Manokwari, Papua Barat. Gedung tersebut membutuhkan energi harian sebesar 20.160 Wh. Setelah dilakukan perhitungan, didapatkan sistem PLTS dengan panel surya monocrystalline 300 Wp sebanyak 16 unit, inverter hybrid MPPT 48V 100A 5KW 6,25KVA sebanyak 1 buah dan baterai 48V 100Ah sebanyak 17 buah. Total biaya pembuatan PLTS Off-Grid (biaya investasi awal + biaya operasional + biaya pemeliharaan) adalah sebesar Rp. 673.000.965.
