Abstract

Abstrak— Di dunia industri penggunaan transformator sebagai pengubah tegangan maupun proteksi sudah sangat banyak. Dalam pengaplikasiannya banyak terjadi kerusakan pada belitan transformator yang terjadi karena kondisi isolasi belitan yang buruk dan beban berlebih. Sehingga pengawasan kinerja transformator menjadi sangat penting. Proses monitoring secara manual dilakukan dengan membaca metering yang terpasang pada transformator. Sedangkan pada transformator tanpa metering proses monitoring dilakukan dengan mengukur secara langsung setiap parameter menggunakan peralatan ukur yang dibutuhkan. Untuk mempermudah proses monitoring tersebut perlu dibuat suatu sistem yang dapat mengukur parameter-parameter transformator secara langsung dan dari jarak jauh. Sistem monitoring transformator secara wireless menggunakan sensor tegangan, arus, dan juga temperatur yang digunakan untuk mendeteksi kondisi temperatur dari belitan transformator. Dari pengujian dapat disimpulkan bahwa hasil perancangan alat monitoring temperatur memiliki angka simpangan (error) sebesar 1.59%, tegangan 0.14%, arus 13.7%. dan daya transformator 4.4%. Pada perancangan ditambahkan perangkat proteksi transformator dengan sebuah fan pendingin yang bekerja ketika temperatur belitan melebihi 40°C dan notifikasi alarm bahaya pada saat temperatur melebihi 70°C. Hasil pengukuran parameter, dan status fan pendingin transformator dapat dibaca pada smartphone melalui koneksi wireless bluetooth hingga jangkauan maksimal 25 meter. Kata kunci: Monitoring, transformator, wireless, temperatur, mikrokontroler.

Abstract

Abstrak - Di Indonesia masih banyak dijumpai daerah-daerah yang belum teraliri arus listrik PLN. Daerah-daerah tersebut menggunakan pembangkit listrik tenaga surya yang biasa dikenal dengan PLTS sebagai suplai energi listriknya. Energi listrik tersebut digunakan untuk keperluan sehari-hari seperti sebagai suplai penerangan rumah tangga. Pada umumnya lampu penerangan yang digunakan rumah tangga menggunakan tegangan AC 220-240 volt. Pada kondisi tertentu lampu penerangan rumah tangga dapat dinyalakan menggunakan tegangan DC. Tegangan DC berkisar dari 80-125 volt dapat digunakan untuk menyalakan lampu penerangan. Untuk itu agar PLTS dapat digunakan secara langsung untuk menyalakan lampu penerangan perlu dilakukan penyamaan level tegangan antara tegangan keluaran PLTS dengan tegangan suplai lampu penerangan.  DC to Dc converter dengan topologi boost konverter digunakan dalam penelitian ini.Tegangan DC sebesar 12 volt dari keluaran PLTS dinaikkan level tegangannya menjadi sekitar 95 volt DC. Output DC to Dc converter ini dapat di gunakan untuk menyalakan lampu led penerangan sebanyak 8 buah. Setelah dilakukan pengujian secara empiris didapatkan hasil, efisisensi DC to DC converter sebesar 70,7 % dengan arus kurang dari 35 mA.Kata kunci: Lampu Penerangan, Solar Cell, DC to DC Converter, Tegangan, Arus. Abstract - In Indonesia, there are still many areas that have not been connected to PLN electricity. These areas use solar power plants commonly known as PLTS as their electricity supply. The electricity is used for daily needs such as household lighting supplies. In general, household lighting uses 220-240 volt AC voltage. Under certain conditions, household lighting can be turned on using DC voltage. DC voltage ranging from 80-125 volts can be used to turn on lighting. For this reason, so PLTS can be used directly to turn on lighting, it is necessary to equalize the voltage level between the PLTS output voltage and the lighting supply voltage. A DC to DC converter with a boost converter topology is used in this study. The DC voltage of 12 volts from the PLTS output is increased to around 95 volts DC. The output of this DC to DC converter can be used to turn on 8 LED lighting lamps. After empirical testing, the results obtained were that the efficiency of the DC to DC converter was 70.7% with a current of less than 35 mA.Keywords: Lighting, Solar Cell, DC to DC Converter, Voltage, Current.

Abstract

This paper presents the design and performance evaluation of a high-voltage direct current (DC) generator based on the Cockcroft–Walton (CW) voltage multiplier for laboratory-scale applications in electrical engineering. Conventional high-voltage generation methods often involve bulky transformers and complex circuitry, making them less suitable for compact and cost-effective laboratory use. To address these limitations, a modular CW-based system is proposed, integrating a high-frequency input source with an optimized diode-capacitor ladder network. The proposed system is designed to achieve high DC voltage output in the kilovolt range while maintaining acceptable levels of ripple and efficiency. Experimental results show that the system can achieve up to 86% of the theoretical output voltage under no-load conditions, with an efficiency of around 70.8%. Furthermore, the ripple voltage of the generated output voltage is very small, demonstrating stable performance suitable for laboratory applications. The proposed design offers a compact, cost-effective, and reliable solution for high-voltage DC generation, making it highly suitable for educational and low-power applications.

Abstract

This research explores the potential of local bio-composites made from bamboo and coconut fiber as sustainable building materials in Indonesia. The construction sector in Indonesia faces significant environmental challenges, particularly the high carbon emissions associated with conventional materials like concrete and steel. The primary objective of this research is to evaluate the environmental and economic benefits of substituting these traditional materials with bio-composites, using Life Cycle Assessment (LCA) and energy optimization simulations. The LCA methodology evaluates the environmental impact of bio-composites across their entire life cycle, comparing them with conventional materials in terms of carbon emissions, energy consumption, and waste. Energy optimization simulations focus on assessing the thermal performance and overall building efficiency when using bio-composites in construction. The main findings suggest that bio-composites exhibit a significantly lower carbon footprint and better thermal insulation properties than concrete and steel, contributing to reduced energy consumption in buildings. Additionally, the use of locally sourced materials like bamboo and coconut fiber offers economic advantages, such as lower transportation costs and support for local economies. The research concludes that bio-composites can serve as viable alternatives to traditional materials, providing both environmental and economic benefits. For successful adoption, the research recommends policy support, technological advancements, and educational initiatives to promote the use of bio-composites in Indonesia’s construction industry.

Abstract

Tanjung Laut Indah Village, Bontang City, is a coastal area that is vulnerable to sea level rise, high tides, and tidal flooding, making an effective early warning mechanism essential for disaster risk reduction. This Community Service Program (PKM) aims to empower the coastal community through the implementation of an early warning system for sea level rise based on an ultrasonic sensor and WhatsApp notifications. The system employs a waterproof ultrasonic sensor integrated with an ESP32 microcontroller to monitor sea level changes in real time. Measurement data are compared with predefined threshold values to classify conditions into Safe, Advisory, Warning, and Emergency levels. When the measured water level exceeds the specified threshold, the system automatically sends warning messages to community members and relevant stakeholders via WhatsApp. The implementation method includes community needs assessment, system design and installation, user training on system operation and maintenance, and evaluation through functional testing and questionnaires. The expected outcomes are improved community awareness, preparedness, and capacity in responding to coastal hazards, the availability of an easy-to-use early warning system, and the establishment of a rapid, accurate, and sustainable information dissemination mechanism to support community-based disaster mitigation.
