Abstract

Suatu besaran umumnya hanya dapat diketahui melalui suatu pengukuran dari besaran tersebut, sehingga pengukuran besaran listrik tegangan dan arus dengan Voltmeter dan Ampermeter telah terintegrasi dalam satu alat ukur portable yang disebut VOmeter. Pemanfaatan alat ukur tersebut dari setiap fungsi pengukuran memiliki lebih dari satu skala pengukuran besaran yang telah ditentukan dan eksis dalam alat ukur, sehingga perubahan nilai skala ukur terbatas sebagaimana umumnya. Keterbatasan tersebut pada dasarnya dapat dikembangkan secara konstruktif sebagai model pengujian untuk pembelajaran sistem rangkuman skala batas ukur sebagai ampermeter, voltmeter maupun ohmmeter. Pengembangan AVO meter sebagai media pembelajaran praktikum sangat memungkinkan sebagai suatu inovasi dengan membuat simulasi perancangan AVOmeter melalui pengujian besaran skala pengukuran dari suatu alat ukur terhadap besarnya nilai komponen tahanan yang diperlukan dengan metode rangkuman tahanan tunggal dan ganda yang pengujiannya menggunakan dua tipe Galvanometer dari AVOmeter yang ada yakni YX 367 TR dan YX 360 TRD. Karena pengaruh tahanan dalam dari kedua Galvanometer tersebut berbeda, maka dengan skala pengukuran besaran yang sama akan mempengaruhi nilai rangkuman tahanan tunggal maupun ganda dari keduanya yang juga berbeda.

Abstract

Renewable energy planning is a complex process, involving multiple dimensions, including natural resource availability, government policies, and socio-economic factors. This study emphasizes the importance of a decision-making approach that is not only technically based, but also considers the social and political factors that influence policy implementation. Decision-making in renewable energy planning is often hampered by information inequality between stakeholders, social resistance, and policy instability that can slow down a sustainable energy transition. Multi-Criteria Decision Making (MCDM) methods have been used to help stakeholders choose the best option, but overly technical approaches can be a barrier in developing countries. Therefore, simpler and more data-driven approaches, such as heuristic models, become more relevant in contexts of uncertainty. This research uses a descriptive qualitative approach through case studies to explore the dynamics of decision-making in renewable energy planning. Data were collected through in-depth interviews, focus group discussions (FGDs), and document analysis. The results show that transparency, open communication and stakeholder participation are essential to overcome social and political barriers and support effective and sustainable renewable energy policy implementation.

Abstract

The increasing demand for electricity in urban areas of Indonesia demands diversification of sustainable energy sources. On-grid Solar Power Plants (PLTS) are a strategic alternative to reduce dependence on fossil fuels and increase household energy resilience. However, optimizing PLTS design still faces technical and structural challenges, such as the mismatch between panel production capacity and electricity consumption patterns, limited space, and weak regulatory support and fiscal incentives. This study uses a qualitative approach with a case study in an urban housing complex to examine the design process, implementation, and obstacles of on-grid PLTS. Data were obtained through in-depth interviews, field observations, and studies of policy and technical documents. The results of the study indicate that the success of PLTS implementation is highly dependent on a design that is contextual to the technical and social characteristics of housing, the support of fiscal policies such as initial subsidies, and institutional integration between communities, local governments, and the private sector. In addition, community-based approaches such as energy cooperatives can increase inclusive system adoption. This study concludes that on-grid PLTS is not only a technical solution for the clean energy transition, but also an instrument of socio-economic transformation that requires multidimensional synergy in its implementation in the urban environment of Indonesia

Abstract

Limited access to electricity in remote areas of Indonesia reflects complex structural issues, including geographic constraints, policy inequalities, and the low effectiveness of centralized approaches. Thousands of villages in the 3T (Disadvantaged, Frontier, and Outermost) regions still do not enjoy reliable electricity, hampering socio-economic development and reinforcing the cycle of poverty. Although Indonesia has great potential for renewable energy—such as solar and wind—its use is still minimal due to infrastructure constraints, investment, and non-contextual development approaches. In this context, a hybrid solar-wind energy system integrated with Internet of Things (IoT) technology offers an efficient and sustainable decentralized solution. IoT enables real-time monitoring, predictive maintenance, and data-driven energy management, which are critical in remote areas with limited technicians and physical access. This study uses a qualitative approach through a literature review to examine the challenges, potential, and policy relevance in developing IoT-based renewable energy systems. The results of the analysis show that transforming energy systems in marginalized areas requires not only technological innovation, but also a paradigm shift towards inclusive energy justice. Therefore, strengthening local capacity and integrating context-based policies are key to realizing a fair, reliable and sustainable energy system in Indonesia.
