Abstract

Electricity is a basic necessity at the household level. Households tend to overlook factors that cause power surges, such as the use of electrical loads that incrush current when turned on. One device that can reduce a incrush current during start-up is softstart. The purpose of this design and testing is to reduce current during the startup of electrical loads and to determine the values of current and electrical energy efficiency before and after the use of the softstart module in real time. The method is design softstart module and powermeter indicator based on Arduino and PZEM-004T. The results show that the voltage at the softstart module output is still within PLN tolerance standards. The voltage and current in test using module for resistive and inductive loads are lower and have an efficiency value of 95% for resistive loads and 94% for inductive loads. The incrush current in both loads increases gradually with a small current value. The conclusion of the study is that the softstart module can reduce starting incrush currents, power consumption, and has good efficiency values. The design of measurement device based on Arduino Uno and the PZEM-004T sensor produced accurate voltage and current measurements.

Abstract

The emergence of information technology has impacted many organisations, which have utilised it to become more efficient and accurate in financial management, including recording membership fees. The MSC Community Organisation of Central Java and South Kalimantan still uses a manual method based on Microsoft Office to record and report membership fees. This causes problems in producing accurate financial reports, as well as the possibility of recording errors and duplicate data. The purpose of this research is to develop an online information system for managing contributions. During the system design process, developers and users can interact directly through the Prototype System Development Life Cycle (SDLC) model. This system was developed using the Django framework and features key components, including a dashboard for real-time financial information, member data management, contribution transaction tracking, and automated monthly and annual report generation. The implementation results show that this system can improve the efficiency and transparency of the organisation's financial management. Therefore, the information system serves as an essential tool for treasurers and members to monitor contributions in an integrated and easy manner. Suggestions for further system development include incorporating payment notification features and integrating digital payment methods.

Abstract

Pembentukan hotspot pada kubikel tegangan menengah 20 kV merupakan salah satu faktor yang dapat menurunkan keandalan dan keselamatan operasi gardu induk, terutama pada kubikel tipe tertutup (close-type) yang tidak memungkinkan akses langsung untuk inspeksi suhu. Metode inspeksi termovisi yang digunakan dalam pemeliharaan rutin PLN bersifat periodik dan manual, sehingga tidak mampu menyediakan pemantauan suhu secara kontinu. Penelitian ini mengusulkan desain dan implementasi sistem peringatan dini berbasis ESP32 untuk mendeteksi potensi hotspot di dalam kubikel 20 kV dengan mengintegrasikan sensor suhu BME280 dan sensor arus SCT013. Sistem ini melakukan pembacaan suhu dan arus secara simultan, mengirimkan data melalui koneksi Wi-Fi ke aplikasi Android menggunakan Firebase, serta memberikan peringatan melalui alarm buzzer dan notifikasi visual saat terdeteksi kondisi termal abnormal. Pengujian dilakukan di Gardu Induk Jatirangon dengan kondisi terkontrol. Hasil menunjukkan bahwa pengukuran suhu pada jarak 30 cm memiliki rata-rata kesalahan relatif sebesar 2,49% bila dibandingkan dengan kamera termografi FLIR, sedangkan pada jarak 35 cm kesalahan meningkat menjadi 7,29%, menegaskan pentingnya posisi sensor dalam memperoleh akurasi optimal. Pengukuran arus dengan sensor SCT013 menunjukkan kesalahan rata-rata sebesar 2,83% terhadap clamp meter, yang masih dapat diterima untuk validasi awal anomali termal. Sistem berhasil memicu alarm ketika suhu mencapai ?38°C dan selisih suhu dengan ambient (?T) berada pada nilai ?4°C dengan arus melebihi 400 A. Hasil penelitian ini membuktikan bahwa sistem berbasis IoT yang dikembangkan mampu mendeteksi anomali termal secara dini pada kubikel tertutup yang tidak dapat dijangkau oleh metode termovisi konvensional, sehingga menawarkan solusi alternatif yang ekonomis dan real-time untuk mendukung pemeliharaan preventif gardu induk.

Abstract

Sehati Ajibarang Gold Shop faces challenges in its manual sales process, leading to inefficiencies, longer queues, and a higher risk of recording errors. This study aims to build a website-based jewelry sales information system to enhance operational efficiency, data accuracy, and reporting quality. The system was developed using the Prototype method with the Laravel framework, allowing iterative evaluation to ensure alignment with user requirements. Research findings indicate substantial improvements, as demonstrated by a Paired Sample T-Test, which revealed a decrease in average transaction processing time from 296.20 seconds to 50.60 seconds. Additionally, a performance assessment based on the ISO/IEC 25000 standard confirmed the system's high quality: Functional Suitability 97.07%, Performance Efficiency 96.63%, Usability 88.90%, and Security 92.23%. The system effectively automates business processes, reduces errors, and delivers rapid and accurate sales reports

Abstract

Sistem hidroponik Nutrient Film Technique (NFT) memerlukan pasokan energi listrik secara kontinu selama 24 jam untuk mengoperasikan pompa sirkulasi nutrisi dan sistem monitoring. Ketergantungan terhadap jaringan listrik konvensional dapat menjadi kendala, terutama pada daerah dengan pasokan listrik yang tidak stabil atau belum terjangkau jaringan PLN. Penelitian ini bertujuan merancang sistem Pembangkit Listrik Tenaga Surya (PLTS) off grid sebagai sumber energi mandiri untuk hidroponik NFT. Metode penelitian dilakukan melalui studi literatur, analisis kebutuhan energi, serta perhitungan kapasitas komponen utama PLTS yang meliputi panel surya, baterai, Solar Charge Controller (SCC), dan inverter. Beban sistem terdiri dari pompa air AC berdaya 40 W dan sistem monitoring berbasis Arduino sebesar 5 W yang beroperasi selama 24 jam per hari sehingga kebutuhan energi harian mencapai 1080 Wh. Dengan mempertimbangkan faktor keamanan dan efisiensi sistem sebesar 80%, diperoleh kebutuhan panel surya sebesar 400 Wp. Kapasitas baterai yang direkomendasikan adalah minimal 150 Ah pada tegangan 12 V, SCC MPPT 50 A, dan inverter pure sine wave berkapasitas 300 W. Hasil perancangan menunjukkan bahwa PLTS off grid mampu menjadi solusi penyedia energi yang andal dan berkelanjutan untuk mendukung operasional sistem hidroponik NFT.
