Abstract

Sultan Muhammad Salahuddin Bima Airport is one of the few airports in Indonesia that has PLTS as a supplier of electrical energy. The existence of PLTS at each airport is a concern for further analysis, so that the potential for electrical energy production from PLTS can be optimal. So the solar module which is the main component of PLTS is very important to pay attention to cleanliness from dirt or dust that can reduce the efficiency and electricity production of PLTS. The measurement of PLTS energy production at Sultan Muhammad Salahuddin Bima Airport before cleaning was 567.56 kWh and after cleaning it was 576.86 kWh. In this measurement, cleaning was carried out on a series of 1 Inveter with a total of 100 solar panels. There is a change in energy production from the measurement results. This condition is due to solar panels that have not been cleaned for 1 year. So that the percentage increase in PLTS energy production at Sultan Muhammad Salahuddin Bima Airport is 1.63%.

Abstract

The installed PLTS capacity in Bali is currently still 3.44% of the target given by the General National Energy Plan (RUEN) of 108 MWp in 2025. The island of Bali has limited land availability so rooftop PLTS is a solution. The design of the rooftop PLTS was carried out on the roof of the Wisti Sabha Building at I Gusti Ngurah Rai International Airport. The research uses PVSyst simulation software while the investment feasibility method uses the Benefit-Cost Ratio (BCR), Net Present Value and discounted payback period (DPP) methods. Based on the simulation results, the rooftop PLTS capacity is 56.6 kWp with energy production of 98,009 kWh/year. The B-CR value obtained is 2.23, the net present value is IDR 707,436,838.55 and the DPP is 7 years, with a rooftop solar system life of 25 years.

Abstract

The growing demand for electricity in the Province of Bali is still largely dominated by the use of fossil fuels and coal. This reliance on conventional energy sources contributes to carbon dioxide (CO₂) emissions and greenhouse gases, which in the long term have a negative impact on the environment. To reduce this dependency, the utilization of renewable energy sources such as Solar Power Plants (PLTS) offers an effective and environmentally friendly solution. The Lecture Building at Udayana University was selected as the study object due to its relatively high electricity consumption. The PLTS system design for this building was based on the available roof area, utilizing all four roof sides. Each side is equipped with 32 solar modules rated at 670 Wp per unit, one inverter with a capacity of 25 kW, and 16 battery units each with a capacity of 200 Ah. The system design was simulated using PVSyst software, and with a total installed capacity of 85.76 kWp, the system is capable of generating approximately 515.8 kWh of electricity per day.

Abstract

The ever-increasing demand for electrical energy demands alternative, environmentally friendly, and sustainable energy sources. Conventional batteries generally rely on synthetic chemicals that have the potential to pollute the environment. One solution that is beginning to be developed is the use of organic waste as an electrolyte source in bio-batteries. This review article discusses the potential of orange peel, fruit, and vegetable waste as a natural electrolyte containing organic acid compounds, particularly citric acid (C₆H₈O₇), as well as mineral acids that can decompose into ions in solution, thus conducting electricity. Various research results show that the acid and water content of organic waste can produce a potential difference when paired with dissimilar metal electrodes, thus generating an electric current. In addition, the pH characteristics and natural electrolyte content of the waste indicate its suitability as a substitute for hazardous chemicals in batteries. Thus, the use of orange peel, fruit, and vegetable waste has the potential to become an environmentally friendly bio-battery innovation that can support efforts to reduce dependence on conventional batteries while contributing to sustainable organic waste management.

Abstract

Sebagai negara agraris, Indonesia membutuhkan inovasi teknologi dalam sektor pertanian, khususnya pada proses perontokan padi. Proses manual perontokan padi seringkali menyebabkan kehilangan hasil, memerlukan waktu lama, dan membutuhkan tenaga yang besar. Untuk mengatasi hal ini, penelitian ini merancang sistem kontrol perontok padi berbasis mikrokontroler dengan sumber daya dari tenaga surya sebagai solusi yang lebih efisien. Sistem ini menggunakan panel surya untuk menyediakan energi bagi motor DC brush pada alat perontok, dengan mikrokontroler Arduino Nano sebagai pengendali utama kecepatan motor. Pengujian dilakukan untuk mengukur kinerja sistem dalam mengatur putaran motor (RPM) dan efisiensi energi dari tenaga surya. Alat perontok padi ini terdiri dari dua bagian: unit perontok dan dudukan panel surya yang terpisah. Pengujian dilakukan sebanyak lima kali pada kecepatan motor 100 RPM, 200 RPM, 300 RPM, 400 RPM, dan 500 RPM. Hasil menunjukkan bahwa peningkatan kecepatan motor berpengaruh pada kapasitas perontokan, dengan kapasitas tertinggi 15,7 kg/jam pada kecepatan 500 RPM. Sistem kontrol berbasis Arduino berhasil mengatur kecepatan motor secara efektif, dan panel surya mampu menyediakan daya yang memadai untuk operasional. Pengujian juga mengindikasikan bahwa konsumsi energi bertambah seiring peningkatan kecepatan motor, namun efisiensi perontokan tetap optimal pada kecepatan tinggi.
