Abstract

With more than 300,000 members, Indonesia's military forces, consisting of the army, navy and air force, have a large need for electricity. A reliable and safe electricity source is a must. Especially in carrying out the task of defending the country in conditions that are critical and threaten the security of the country. For this reason, the use of microgrids can be a solution for energy independence. In addition, using microgrids consisting of renewable energy sources helps the government increase the renewable energy share. This research discusses the design and application of microgrids in the military. The study case is done in one of military facility in Indonesia. The first step is to identify the type of the system if it is on grid or off grid, then calculate the load, source of energy and decide the control system. In this study case where the load is 3082 kWh/day, it require 860pcs PV of 320Wp capacity with cycle charging controller systems and Diesel Generator with capacity of 260kW. It is hoped that it can be a guide for the military in Indonesia in implementing microgrids.

Abstract

This study evaluates the financial viability of grid-connected rooftop photovoltaic (PV) systems across seven Indonesian residential types (2.75-19.8 kWp) under current market conditions. Using a discounted cash flow model with 8% discount rate and a 20-year project lifetime, key metrics including Net Present Value (NPV), Levelized Cost of Electricity (LCOE), and payback period have been analysed. Results demonstrate that system economics improve significantly with scale: while small systems (2.75 kWp) yield negative NPV (-Rp 9.71 million) and 12.4-year payback, larger installations (>7.7 kWp) achieve positive NPV (up to Rp 89.95 million for 19.8 kWp systems) and sub-10-year payback periods. The LCOE ranges from Rp 1,082-1,205/kWh, representing 11-36% cost savings compared to PLN's tiered tariffs (Rp 1,352-1,699.53/kWh). Monthly savings scale proportionally with system size, from Rp 323,378 (2.75 kWp) to Rp 2.84 million (19.8 kWp). A critical 7.7 kWp capacity threshold emerges for self-sustaining viability without subsidies, with 3500+ VA customers benefiting most due to higher avoided tariffs. These findings provide policymakers with evidence to design tiered incentive programs targeting underperforming market segments (<6 kWp systems), while confirming the commercial readiness of larger residential-commercial hybrid systems in Indonesia's solar transition.

Abstract

Era digitalisasi menuntut seorang pendidik untuk aktif dengan pemanfaatan tools yang selaras dengan kemajuan teknologi dalam hal proses belajar-mengajar di kelas. Guru dituntut untuk menciptakan suasana kelas yang menarik, kreatif, dan efektif sepanjang proses belajar. Oleh karena itu, diperlukan penerapan metode pembelajaran interaktif yang memungkinkan terjadinya komunikasi dua arah antara guru dan siswa. Hal ini mendorong siswa untuk ikut aktif berpartisipasi dalam proses belajar-mengajar, dan menyampaikan pendapat, serta respon terhadap materi yang diajarkan. Namun, tanpa dukungan teknologi dan media yang tepat, pelaksanaan metode ini menjadi sulit dan menghambat tercapainya tujuan pembelajaran secara optimal. Meskipun banyak pendidik sudah familiar dengan konsep dan metode pembelajaran interaktif, penerapannya masih belum maksimal. Oleh karena itu, kegiatan pengabdian kepada masyarakat yang dilaksanakan di madrasah difokuskan pada pemanfaatan media pembelajaran interaktif dengan menggunakan platform SLIDO, yang telah terbukti efektif dan menarik bagi para penggunanya. Kegiatan pengabdian ini diimplementasikan dengan tujuan untuk memberikan pelatihan dan pembekalan kepada para guru dalam mengoptimalkan penggunaan media pembelajaran interaktif ini.
