Abstract

Remote rural villages in Indonesia do not have sufficient infrastructure to maintain an economically sound energy generation and distribution. Sparse area and low population hinder national electricity company PLN (Perusahaan Listrik Negara) to connect these remote rural villages to the national grid. Most of the villages lie in the palm oil plantation, where renewable biomass resources from the Palm Oil Mill wastes are plentiful. Untapped biomass resources could be the answer to energy security issue in the remote rural area. Berau Regency in East Kalimantan Province has many villages located in the palm oil plantation area. Nearly all of the palm oil processing plants in Berau use palm shell and fiber to power the mill. Some of them have the agreement with PLN to sell their excess power. This scheme can be applied to provide electricity to villages around the palm oil mills. However, it is unreliable since the amount of excess electricity produced keeps fluctuating. This paper explores the idea of village-owned biomass/biogas power plant that is owned and operated by the villagers themselves. That way, the village can ensure its energy security using sustainable local resources. In conclusion, the investment cost of biomass/biogas power plant cannot be provided by village annual budget. Although the villages in Berau Regency have a relatively high annual budget, wich is about Rp2 billion to Rp5 billion, the investment costs of biomass/biogas power plant is even higher. According to the economic analysis of biomass/biogas power plant development, a biomass power plant with 1,7 MW capacity can cost up to Rp46 billion. Moreover, a biogas power plant with 1 MW capacity costs around 41 billion. It is not possible for the villages to finance the power plant development by themselves. Therefore, the private sector is needed to implement biomass/biogas utilization for rural electrification from palm oil waste. With the Net Present Value (NPV) up to Rp 65.078.072.000,00 and Internal Rate of Return (IRR) of 20% for biomass power plant and Rp14.330.070.000,00 and 10% for biogas power plant, it is economically feasible and profitable for private enterprise to undertake. The challenges are for the government to encourage the private sector to invest and for PLN to sign Power Purchase Agreement with these palm oil enterprises rather than just Excess Power Agreement.

Abstract

Potensi perikanan tangkap di perairan Kampung Ausem meliputi ikan pelagis dan demersal, serta masyarakat pesisir yang menggunakan pancing ulur untuk menangkap ikan tersebut. Dengan mempertimbangkan potensi sumber daya dan peluang pengembangan, serta kehidupan sosial ekonomi dan budaya masyarakat setempat, pengelolaan dan pemanfaatan sumber daya di Kampung Ausem, Kabupaten Kepulauan Yerui, sangatlah penting. Oleh karena itu, perlu dilakukan analisis pendapatan nelayan tradisional di Kampung Ausem. Pengumpulan data primer dan sekunder dilakukan pada bulan Juni hingga Agustus 2025 di Kampung Ausem. Secara keseluruhan, ada 23 nelayan yang menggunakan perahu dayung kayu di Kampung Ausem. Mereka berusia di atas 46 tahun, sebagian besar tidak menyelesaikan sekolah dasar, telah menjadi nelayan selama 8 tahun, sebagian besar sudah menikah, dan memiliki 4 hingga 6 anggota keluarga. Karakteristik sosial ekonomi menunjukkan bahwa responden telah tinggal di Kampung Ausem untuk waktu yang lama dan mencari nafkah sebagai nelayan dengan menangkap ikan dan berkebun ketika mereka tidak melaut. Pendapatan bersih yang diperoleh oleh nelayan individu dalam setahun dari kegiatan ini adalah Rp. 60.240.434,78/tahun. Karakteristik sosial ekonomi menunjukkan bahwa responden yang telah tinggal di Kampung Ausem untuk waktu yang lama mencari nafkah sebagai nelayan dengan menangkap ikan dan berkebun ketika mereka tidak melaut. Pendapatan bersih yang diperoleh oleh nelayan individu dalam setahun dari kegiatan ini adalah Rp. 60.240.434,78 per tahun. Dengan demikian, setiap nelayan memperoleh penghasilan bulanan sebesar Rp. 5.020.036,23, sedangkan upah minimum regional (UMR) di Provinsi Papua adalah Rp. 4.285.850. Hal ini menunjukkan adanya peningkatan kesejahteraan nelayan di Kampung Ausem, Kecamatan Pulau Yerui, Kabupaten Kepulauan Yapen.

Abstract

In this digital era, the competitiveness of small banks has decreased, and many bank consolidation phenomena have occurred. This study aims to examine the effect of bank soundness and efficiency on profitability in the face of competition and the current bank consolidation or merger phenomenon. Determination of variables refers to Bank Indonesia standards in measuring bank performance using the RGEC method approach consisting of the ratio of LDR, NIM, BOPO, NPL, CAR, and prime lending rate (SBDK), while bank profitability is represented by ROA. The research object is the bank category BUKU 1 - 4 which is supervised by OJK and listed as issuers on the Indonesia Stock Exchange during 2014 - 2017. The sampling technique used is purposive sampling so that from 102 banks 34 banks were obtained which were used as research objects. The data analysis technique used is multiple regression analysis and Anova comparison test. Based on the results of data testing, it is known that simultaneously and partially the ratios of LDR, NIM, BOPO, NPL, CAR, and SBDK have an effect on ROA. In comparison to the average BOPO, prime lending rate, and ROA variables, there are significant differences with bank categorization BUKU 1-4.
