Penelitian ini bertujuan mengembangkan sistem keamanan inovatif menggunakan sensor magnetometer HMC5883L dan magnet neodymium sebagai tag untuk mendeteksi dan mencegah pencurian peralatan studio musik. Metodologi penelitian menggunakan pendekatan rekayasa teknik dengan implementasi sistem yang terdiri dari enam sensor HMC5883L, sensor ultrasonik HC-SR04, multiplexer I2C TCA9548A, dan sistem notifikasi berbasis Telegram. Pengujian dilakukan di Pandawa Music Studio & Café dengan serangkaian evaluasi meliputi kalibrasi sensor, pengujian berbagai grade magnet neodymium (N42-N54), dan validasi sistem secara keseluruhan. Hasil penelitian menunjukkan sensor HMC5883L memiliki perbedaan pembacaan rata-rata 9,16% dibandingkan alat ukur standar, dengan magnet neodymium N54 memberikan performa optimal hingga jarak 30 cm. Sistem berhasil mendeteksi peralatan studio dengan tingkat keberhasilan 100%, tanpa false positive, dan rata-rata delay notifikasi Telegram 2,4 detik. Dapat disimpulkan bahwa sistem yang dikembangkan efektif dalam mendeteksi dan mencegah pencurian peralatan studio musik, dengan saran pengembangan meliputi integrasi dengan platform IoT tambahan, penambahan modul kamera, dan penggunaan sensor magnetometer dengan sensitivitas lebih tinggi. Abstract Music studio rentals face serious challenges in protecting their valuable equipment from theft, with BPS data recording 1,140 theft cases during the 2019-2021 period. This research aims to develop an innovative security system using HMC5883L magnetometer sensors and neodymium magnets as tags to detect and prevent music studio equipment theft. The research methodology employs a technical engineering approach with system implementation consisting of six HMC5883L sensors, HC-SR04 ultrasonic sensor, I2C TCA9548A multiplexer, and Telegram-based notification system. Testing was conducted at Pandawa Music Studio & Café with a series of evaluations including sensor calibration, testing of various neodymium magnet grades (N42-N54), and overall system validation. Research results show that the HMC5883L sensor has an average reading difference of 9.16% compared to standard measuring instruments, with N54 neodymium magnets providing optimal performance up to 30 cm distance. The system successfully detected studio equipment with a 100% success rate, no false positives, and an average Telegram notification delay of 2.4 seconds. It can be concluded that the developed system is effective in detecting and preventing music studio equipment theft, with development suggestions including integration with additional IoT platforms, addition of camera modules, and use of magnetometer sensors with higher sensitivity.

Abstract

Abstrak Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pemantauan dan kontrol waktu studio musik berbasis RFID yang terintegrasi dengan IoT. Sistem ini menggabungkan website reservasi online, metode pembayaran Midtrans, REST API, dan Sistem RFID untuk memberikan solusi otomatis dalam pengelolaan waktu, validasi akses pengguna, serta kontrol perangkat elektronik seperti lampu dan stop kontak. Website memungkinkan pengguna untuk melakukan reservasi, top-up saldo poin, dan memilih jadwal sewa dengan transaksi yang aman dan otomatis. Hasil pengujian menggunakan teknik Blackbox Testing menunjukkan bahwa perangkat lunak maupun perangkat keras bekerja sesuai dengan rancangan dan pemrograman awal. Integrasi pembayaran dengan Midtrans memastikan saldo diperbarui secara otomatis tanpa adanya kesalahan manual. Sistem ini memberikan solusi otomatis untuk pengelolaan studio musik dan berpotensi diadaptasi ke aplikasi lain yang membutuhkan reservasi online, pembayaran digital, otomatisasi kontrol, dan manajemen berbasis waktu. Abstract This study aims to design and implement a music studio time monitoring and control system based on RFID integrated with IoT. The system combines an online reservation website, Midtrans payment method, REST API, and RFID to provide an automated solution for time management, user access validation, and electronic device control such as lights and power outlets. The website allows users to make reservations, top up point balances, and select rental schedules with secure and automated transactions. Testing using the Blackbox Testing method shows that both software and hardware function according to the initial design and programming. The integration of Midtrans payments ensures that balances are updated automatically without manual errors. This system provides an automated solution for music studio management and has the potential to be adapted for other applications requiring online reservations, digital payments, automation control, and time-based management.

Abstract

The rapid development of modern industries increasingly relies on automation systems to improve product quality, shorten production time, and reduce human labor costs. One of the technologies used in automation systems is the Programmable Logic Controller (PLC), which has replaced conventional control systems. To meet industry demands, students in the Electrical Engineering Education Program at Universitas Negeri Jakarta (UNJ) are expected to have skills in operating and programming PLCs. However, based on observations, students' understanding of PLC materials remains low, and the laboratory's supporting facilities for PLC learning are still limited. This research aims to develop a PLC Trainer Kit and its corresponding Jobsheet as a Practicum Support Tool in the Programmable Logic Control course. The development method used is Research and Development (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The research results show that the developed PLC Trainer Kit obtained a feasibility score of 97.3% from material experts, 89% from media experts, and 94% from student trials. Thus, it can be concluded that this PLC Trainer Kit is highly suitable as a learning aid in the Electrical Engineering Education Program at UNJ. This study is expected to contribute to improving students' understanding of PLCs and facilitating more interactive and applicable learning.

Abstract

Field lighting in schools is one of the important elements that support educational activities, especially at night. This study aims to evaluate the implementation of a solar panel-based lighting system at Madinathul Ilmi School located in Muara Gembong District. By utilizing renewable energy sources, namely solar energy, this system is designed to overcome the problem of limited access to electricity in remote areas and reduce dependence on fossil energy sources. The research methodology includes the planning, installation, and performance evaluation stages of the lighting system used. Analysis was carried out on energy efficiency, operational costs, and the resulting environmental impacts. The results of the study indicate that the solar panel-based lighting system is able to provide adequate lighting with lower operational costs compared to conventional systems. In addition, the use of solar panels also contributes positively to reducing carbon emission.

Abstract

Emisi gas buang asap knalpot kendaraan bermotor yang muncul karena proses pembakaran yang tidak sempurna dapat berdampak negatif pada kesehatan dan lingkungan. Di antaranya adalah gas hidrokarbon (HC) dan karbon monoksida (CO). Paparan gas CO di atas batas aman dapat menimbulkan masalah kesehatan, sedangkan paparan gas HC dengan jenis gas metana (CH4), juga dapat menyebabkan gangguan kesehatan serta memiliki daya rusak atmosfer yang besar, sehingga dapat berkontribusi pada perubahan iklim dan lingkungan. Tujuan penelitian ini adalah merancang suatu sistem monitoring nilai konsentrasi gas CO dan HC pada emisi gas buang kendaraan bermotor guna membantu para pengguna kendaraan bermotor memenuhi standar kendaraan yang layak beroperasi di jalan. Penelitian ini dilakukan dengan menggunakan metode Reverse Engineering. Proses pengukuran konsentrasi CO dilakukan dengan menggunakan sensor MQ-7, sedangkan pengukuran konsentrasi HC menggunakan sensor MQ-5. Untuk memproses hasil pengukuran, digunakan mikrokontroler Arduino Uno dan ESP32. Sedangkan untuk hasil pengukuran konsentrasi CO dan HC akan ditampilkan pada layar OLED SSD1306. Hasil pengukurannya dapat ditinjau ulang pada halaman website yang dapat diakses secara online. Dalam penelitian ini, efektivitas alat uji emisi gas berbasis mikrokontroler dibandingkan dengan alat uji gas Analyzer AGS-688. Berdasarkan hasil pengujian variasi waktu, kedua alat memiliki selisih akurasi 4.50–7.06% dalam mengukur CO dan 2.03–7.10% dalam mengukur HC. Pada pengujian variasi jarak, selisih akurasi adalah 5.04–28.57% untuk CO dan 2.02–19.68% untuk HC. Hasil pengukuran juga menunjukkan bahwa nilai konsentrasi CO dan HC dapat terbaca dengan baik pada halaman website yang dapat diakses secara online.
