Abstract

Penelitian ini bertujuan untuk mengembangkan prototype lux meter berbasis penentuan titik pengukuran otomatis yang mampu membantu proses evaluasi intensitas pencahayaan ruangan sesuai dengan ketentuan SNI 7062:2019. Latar belakang penelitian ini adalah belum terintegrasinya sistem pengukuran dimensi ruangan pada lux meter konvensional sehingga penentuan titik pengukuran masih dilakukan secara manual dan berpotensi menimbulkan human error. Penelitian menggunakan metode rekayasa (engineering) dengan pendekatan Forward Engineering yang meliputi tahap analisis kebutuhan, perancangan sistem, implementasi, serta pengujian dan evaluasi. Prototype dikembangkan menggunakan mikrokontroler ESP32-S3 N16R8 yang terintegrasi dengan sensor intensitas cahaya TSL2561, sensor pengukur jarak JRT M88B, dan layar TFT touchscreen sebagai antarmuka pengguna. Sistem mengimplementasikan algoritma penentuan titik pengukuran berdasarkan luas ruangan sesuai SNI 7062:2019, kemudian melakukan pengukuran intensitas cahaya pada setiap titik, menghitung nilai rata-rata pencahayaan secara otomatis, dan membandingkan hasilnya dengan standar intensitas pencahayaan pada SNI 6197:2020. Hasil penelitian menunjukkan bahwa prototype berhasil mengintegrasikan seluruh komponen sehingga mampu mengukur dimensi ruangan dengan presisi (error 0% pada sensor JRT M88B), menentukan jumlah dan posisi titik pengukuran secara otomatis, serta menampilkan panduan pengukuran pada layar sentuh. Meskipun sensor intensitas cahaya (TSL2561) masih menunjukkan error sebesar 39%-44%, sistem komputasi perangkat terbukti sangat akurat dalam menghitung nilai rata-rata pencahayaan, dengan selisih yang sangat minim (0,04 lux) dibandingkan perhitungan komputasi manual. Sebagai kesimpulan, prototype lux meter yang dikembangkan telah berhasil secara fungsional dalam mengotomatisasi penentuan titik ukur pencahayaan sesuai dengan standar SNI, sehingga dapat meningkatkan efektivitas proses pengukuran dan secara signifikan mengurangi potensi kesalahan manusia dalam mengevaluasi pencahayaan ruangan ***** This study aims to develop a lux meter prototype based on automatic measurement point determination to support indoor lighting evaluation in accordance with SNI 7062:2019. The research was motivated by the lack of integration between conventional lux meters and room dimension measurement, causing measurement points to be determined manually and increasing the possibility of human error. The study employed an engineering method using the Forward Engineering approach, consisting of requirements analysis, system design, implementation, testing, and evaluation. The prototype was developed using an ESP32-S3 N16R8 microcontroller integrated with a TSL2561 light intensity sensor, a JRT M88B laser distance sensor, and a TFT touchscreen as the user interface. The system implements an algorithm to automatically determine measurement points based on room dimensions according to SNI 7062:2019, performs illuminance measurements at each point, calculates the average illuminance, and compares the results with the lighting standard specified in SNI 6197:2020. The results indicate that the prototype successfully integrates all components, enabling it to measure room dimensions with high precision (0% error on the JRT M88B sensor), automatically determine the number and position of measurement points, and display measurement guidance on the touchscreen. Although the light intensity sensor (TSL2561) still exhibits an error of 39%-44%, the device's computational system proved highly accurate in calculating the average illuminance, with a minimal margin of difference (0.04 lux) compared to manual computational calculations. In conclusion, the developed lux meter prototype has succeeded functionally in automating the determination of lighting measurement points in compliance with SNI standards, thereby increasing the effectiveness of the measurement process and significantly reducing the potential for human error in evaluating room lighting.
