Abstract

This study presents a contextually tailored off-grid hybrid energy system consisting of solar photovoltaic (PV), diesel generator (DG), and battery storage, designed for the remote mountains village of Jifak in Papua, Indonesia. The objective is to evaluate the technical, economic, environmental, and social feasibility of electrification in underserved regions. A comprehensive feasibility analysis was conducted using HOMER software, incorporating realistic communal load profiles, National Aeronautics and Space Administration (NASA) climate data, and field-based social assessments. The optimized system achieved a net present cost (NPC) of $10.43 million, a levelized cost of energy (LCOE) of $0.5095/kWh, and annual emissions of 7,965 kg CO₂. Sensitivity analysis was performed on fuel cost, discount rate, and inflation rate to assess system robustness. Beyond the technical metrics, the study assessed the socio-economic impacts of electrification, revealing improvements in lighting quality, education, productivity, income generation, and environmental awareness. The findings provide a replicable model and decision-making framework for policymakers and practitioners aiming to deploy low-carbon, sustainable electrification strategies in similarly remote regions.

Abstract

Kualitas jagung yang dihasilkan oleh para petani sangat dipengaruhi oleh proses pengeringan pasca panen. Selain mengandalkan pengeringan langsung di bawah panas matahari, petani juga sangat membutuhkan alat pengering yang memadai, terutama jika masa panen berlangsung di musim hujan. Kegiatan ini bertujuan untuk memperkenalkan pengering tenaga surya (solar dryer) kepada masyarakat petani jagung, khususnya pada Kelompok Tani Berkat Rama yang berkedudukan di Kampung Bibiosi, Distrik Arso, Kabupaten Keerom sebagai salah satu sentra jagung di Jayapura. Pada kegiatan pengabdian ini, solar dryer yang disosialisasikan dilengkapi dengan kolektor sekunder dan turbin ventilator. Berdasarkan hasil penelitian sebelumnya, proses pengeringan menggunakan solar dryer dengan kolektor sekunder dan turbin ventilator akan berlangsung lebih cepat serta kualitas produk hasil pengeringan akan lebih baik karena temperatur di dalam ruang pengeringan dapat terjaga (tidak terlalu tinggi). Selain itu dengan menggunakan solar dryer maka proses pengeringan akan aman dari gangguan hujan dan hewan/ternak. Kegiatan PKM ini mendapat sambutan dan animo yang baik dari para petani jagung yang tergabung dalam Kelompok Tani Berkat Rama dengan mengikuti kegiatan sosialisasi hingga selesai. Kelemahan dari solar dryer adalah daya tampung yang masih terbatas sehingga masyarakat petani mengusulkan agar bisa dibantu oleh pemerintah setempat dalam hal pengadaan alat dan bahan untuk membangun sebuah alat pengering jagung yang berukuran memadai.

Abstract

This study examines the bidirectional relationship between economic growth and human development in Indonesia’s Papua Region, a context characterized by persistent welfare disparities despite the implementation of Special Autonomy. Utilizing a balanced panel dataset covering Papua and West Papua provinces, the research applies a dual fixed-effects panel regression model estimated via Feasible Generalized Least Squares with Panel-Corrected Standard Errors to probe the nuanced feedback connections between Gross Regional Domestic Product (GRDP) per capita and the Human Development Index (HDI). The investigation confirms a vigorous, reciprocal, and mutually augmenting association between economic advancement and human progression, where increases in per capita GRDP significantly predict improvements in HDI, and advancements in HDI in turn drive substantial elevations in regional economic output. Beyond the core economic and human development variables, electricity consumption per capita emerges as a consistent, positive catalyst in both models, functioning as a "keystone catalyst" that simultaneously supports standard of living improvements and economic productivity. Conversely, population growth is identified as exerting a drag on per capita income, highlighting a "denominator effect," where rapid demographic expansion dilutes economic gains even as it expands the potential human capital base. The findings substantiate the existence of a virtuous cycle of development in Papua but underscore that achieving inclusive welfare outcomes requires integrated policy interventions that synchronize economic productivity, human capability enhancement, and energy infrastructure expansion.
