Abstract

Pemanfaatan Pembangkit Listrik Tenaga Surya (PLTS) pada rumah apung menjadi salah satu solusi penyediaan energi listrik mandiri di wilayah perairan. Namun, pada kondisi intensitas radiasi matahari tinggi dan kebutuhan beban yang relatif rendah, baterai sering mencapai kondisi pengisian penuh sehingga sebagian energi listrik yang dihasilkan panel surya tidak termanfaatkan secara optimal. Selain itu, durasi baterai yang terlalu lama berada pada kondisi State of Charge (SOC) tinggi berpotensi mempercepat penurunan performa dan umur pakai baterai. Penelitian ini bertujuan mengembangkan model konseptual pemanfaatan surplus energi PLTS untuk produksi es balok pada rumah apung melalui penggunaan freezer sebagai beban produktif (productive load). Metode yang digunakan adalah analisis konseptual berbasis neraca energi yang meliputi identifikasi karakteristik sistem PLTS 700 Wp dengan baterai 24 V 200 Ah, analisis produksi energi, identifikasi surplus energi, pemodelan freezer berkapasitas 200–500 liter, serta estimasi potensi produksi es berdasarkan energi yang tersedia. Hasil analisis menunjukkan bahwa sistem PLTS berpotensi menghasilkan energi harian sekitar 2,8 kWh, dengan surplus energi sekitar 1,2 kWh per hari setelah kebutuhan beban utama terpenuhi. Surplus energi tersebut dapat dimanfaatkan untuk mengoperasikan freezer dan menghasilkan sekitar 5–6 kg es per hari. Selain meningkatkan pemanfaatan energi surya, penggunaan freezer sebagai beban produktif berpotensi mengurangi durasi baterai berada pada kondisi SOC tinggi sehingga mendukung pengelolaan energi yang lebih efektif. Penelitian ini menunjukkan bahwa pemanfaatan surplus energi PLTS untuk produksi es balok merupakan pendekatan yang menjanjikan dalam meningkatkan utilisasi energi surya sekaligus mendukung kebutuhan rantai dingin perikanan pada rumah apung skala kecil.

Abstract

The continuous growth of electricity demand requires a reliable and efficient distribution system. The SM3 Feeder at the Tomohon Main Substation (GI Tomohon), managed by PT PLN (Persero) UP3 Manado, is a critical medium-voltage distribution network serving the Tomohon city centre area. The feeder currently employs overhead aerial conductors that are vulnerable to environmental disturbances such as extreme weather, strong winds, lightning, and vegetation contact, which leads to frequent outages and reduced supply quality. This study investigates the implementation of a 20 kV underground cable network on the SM3 Feeder as a strategy to improve system reliability. The methodology encompasses field surveys, technical data collection, and comparative performance analysis of the distribution system before and after underground cable implementation. Quantitative analysis was applied to evaluate technical parameters including fault frequency, and the reliability indices SAIDI and SAIFI, while qualitative analysis is used to assess the practical advantages and constraints observed during field implementation. Results demonstrate that underground cable implementation significantly reduces environmentally induced faults, providing improvements in safety, system reliability, and urban aesthetics. Although capital investment and installation costs are considerably higher than those of overhead networks, the long-term operational benefits including substantial reduction in fault frequency, improved supply continuity, and longer service life justify the investment. Underground cable networks are thus confirmed as an effective solution for enhancing power distribution quality and reliability, particularly in urban areas with high fault incidence.

Abstract

Load imbalance on low-voltage distribution networks arises from the uneven distribution of single-phase loads across a three-phase system, resulting in elevated neutral currents, increased power losses, and degraded voltage quality. This research systematically analyzes the degree of load imbalance on the low-voltage distribution network of SM3 Feeder, Tomohon Main Substation, PT PLN (Persero) UP3 Manado, using phase current measurements, neutral current readings, and customer load data collected from field surveys. The methodology employed phase current measurements, neutral current readings, and customer load data collected from field surveys at five measurement points representing diverse loading conditions and network topologies. The percentage load imbalance (PLI) was calculated and benchmarked against SPLN D3.002-1:2007 and IEEE Std 1159 standards, with measurements conducted during morning, afternoon, and evening peak periods. Findings reveal significant imbalance in four of five assessed feeder segments, with the most critical level reaching 31.7% at MP-5. Elevated neutral currents produced measurable additional power losses in the neutral conductor, and customer terminal voltage violations were confirmed at MP-3 and MP-5, with the most severe deviation reaching ?9.7% below the nominal 220 V. The study concludes that systematic load redistribution at MP-5, MP-3, and MP-1, combined with mandatory phase allocation for new connections and quarterly monitoring protocols, is required to restore standard compliance and improve network efficiency, power quality, and reliability on the SM3 Feeder distribution system.

Abstract

The rapid development of technology has significantly transformed trade dynamics and economic growth in Indonesia. However, the benefits of digital transformation remain unevenly distributed across regions, creating a digital divide that hinders inclusive development. This study aims to analyze the disparity between internet penetration and its economic utilization, as well as to identify barriers faced by non-connected populations in participating in the digital economy. A mixed-method approach was employed, combining quantitative descriptive analysis of secondary data from the Badan Pusat Statistik (BPS) and the Asosiasi Penyelenggara Jasa Internet Indonesia (APJII) (2025), with qualitative thematic analysis of policy documents and literature on digital inclusion. The findings reveal that although 80.67% of Indonesia's population are internet users, more than 55 million people remain unconnected, primarily in rural and remote areas. Furthermore, connectivity alone does not guarantee economic participation; limited digital literacy, inadequate infrastructure, low trust in digital financial services, and cultural barriers significantly impede the utilization of digital platforms for productive economic activities. The study also finds that existing policies tend to focus disproportionately on infrastructure expansion while neglecting capacity-building and community empowerment strategies. This research contributes to the formulation of more comprehensive digital development policies by emphasizing the necessity of integrating infrastructure investment with digital literacy programs, MSME empowerment, and social inclusion frameworks. The findings imply that bridging the digital divide requires a multidimensional approach that addresses not only access but also skills, trust, and institutional support to ensure sustainable and equitable digital transformation in Indonesia.
