Abstract

This paper presents development of electric motor speed control system for railway vehicle roller test rig. For maneuver flexibility reason, each must be independently controlled, and consequently, must be precisely controlled to prevent excessive yaw motion of the vehicle. To fulfill this requirement, a control system is built on a 3:10 scaled single roller rig which is driven by a low-cost motor, i.e., AC induction motor. The scale implies acceleration requirement as 1.1 m/s2 and targeted speed as 2000 RPM. The system adopts PID control strategy with Ziegler-Nichols as its tuning method. As a result, the system yields settling time as 12.42 second with steady-state error of 0.75% when the system is being subjected to a step function input. Additionally, the system manages to reject disturbance which is proven by its ability to recover its speed once an amount of disturbance torque is applied. The findings indicate that AC induction motors with PID control strategy offers considerable speed performance over AC servo motors, which are typically much more costly. These findings indicate that AC induction motors with a PID control strategy offer considerable speed performance, making them a viable, cost-effective alternative to the typically more expensive AC servo motors. Moreover, the results have been validated against the roller-rig's operational conditions, confirming that the system meets the required performance criteria.

Abstract

Penelitian ini meninjau perencanaan dan optimasi Pembangkit Listrik Tenaga Mikrohidro (PLTMH) di Indonesia, dengan fokus pada aspek teknis, ekonomi, dan sosial. Berdasarkan tinjauan literatur, perencanaan yang matang sangat penting untuk memastikan pemanfaatan potensi lokal secara optimal, mencakup pemilihan lokasi, debit, head, serta turbin yang sesuai. Optimasi teknologi, seperti sistem stabilisasi tegangan dan pintu air otomatis, terbukti meningkatkan efisiensi sistem. Namun, penerapan teknologi canggih seperti AI dan smart grid masih terbatas. Penelitian ini mengidentifikasi gap dalam integrasi aspek sosial-ekonomi dan teknologi, serta menyarankan pengembangan model perencanaan yang lebih adaptif dan integrasi teknologi terbaru untuk meningkatkan keberlanjutan dan efisiensi PLTMH di masa depan.   This study reviews the planning and optimization of Micro-Hydro Power Plants (MHPP) in Indonesia, focusing on technical, economic, and social aspects. Based on the literature review, effective planning is crucial to ensure the optimal utilization of local resources, including site selection, flow rate, head, and appropriate turbine selection. Optimization technologies, such as voltage stabilization systems and automatic gate systems, have proven to enhance system efficiency. However, the application of advanced technologies like AI and smart grids remains limited. This study identifies gaps in the integration of socio-economic aspects and technology, and recommends the development of a more adaptive planning model and the integration of cutting-edge technologies to enhance the sustainability and efficiency of MHPPs in the future

Abstract

Pulau Bungin, yang terletak di Kecamatan Alas, Kabupaten Sumbawa, merupakan salah satu pulau terpadat di dunia dengan akses energi listrik yang masih bergantung pada Pembangkit Listrik Tenaga Diesel (PLTD). Peningkatan permintaan energi di wilayah ini menimbulkan tantangan serius, terutama terkait tingginya biaya operasional, ketergantungan pada bahan bakar fosil, dan dampak lingkungan. Penelitian ini mengusulkan implementasi sistem energi hibrid berbasis Pembangkit Listrik Tenaga Surya (PLTS) dan PLTD sebagai solusi alternatif yang berkelanjutan. Melalui simulasi menggunakan perangkat lunak HOMER, sistem dianalisis berdasarkan parameter utama seperti efisiensi energi, Levelized Cost of Energy (LCOE), dan Net Present Cost (NPC). Hasil simulasi menunjukkan bahwa integrasi PLTS mampu meningkatkan efisiensi sistem sebesar 99,8%, dan menurunkan emisi CO₂ secara signifikan. LCOE sistem hibrid juga lebih kompetitif dibandingkan sistem PLTD murni. Implikasi praktis dari studi ini menunjukkan bahwa sistem hibrid dapat menjadi solusi energi yang andal, hemat biaya, dan ramah lingkungan untuk daerah terpencil seperti Pulau Bungin, serta mendukung pencapaian target bauran energi nasional.   Bungin Island, located in Alas District, Sumbawa Regency, is one of the most densely populated islands in the world, with access to electricity still dependent on diesel power plants (PLTD). Increased energy demand in this region poses serious challenges, particularly in terms of high operational costs, dependence on fossil fuels, and environmental impacts. This study proposes the implementation of a hybrid energy system based on Solar Power Plants (SPP) and PLTD as a sustainable alternative solution. Through simulations using HOMER software, the system was analyzed based on key parameters such as energy efficiency, Levelized Cost of Energy (LCOE), and Net Present Cost (NPC). The simulation results show that integrating PLTS can increase system efficiency by 99.8% and significantly reduce CO₂ emissions. The LCOE of the hybrid system is also more competitive than that of a pure PLTD system. The practical implications of this study indicate that the hybrid system can serve as a reliable, cost-effective, and environmentally friendly energy solution for remote areas like Bungin Island, while also supporting the achievement of national energy mix targets.
