Abstract

Proses fotosintesis sangat berperan penting bagi tumbuhan, terdapat indikator yang terlibat dalam proses fotosintesis, salah satunya yaitu intensitas cahaya. Terkait pencahayaan sendiri, ada beberapa parameter yang perlu diperhatikan yaitu, kualitas, intensitas, dan fotoperiode. Kualitas cahaya berkaitan dengan Photosynthetically Active Radiation (PAR) yaitu rentang cahaya dalam spektrum elektromagnetik dan Intesitas berkaitan dengan banyaknya cahaya yang diterima per satuan luas yang biasa dinyatakan dalam Photosynthetic Photon Flux Density (PPFD). Pencahayaan yang tidak tepat pada tanaman akan memberikan dampak yang negatif terhadap pertumbuhan tanaman itu sendiri, dengan ini maka perlu adanya sistem monitoring kualitas spektrum cahaya sebagai upaya mengoptimalkan proses fotosintesis tersebut. Pada penelitian ini difokuskan untuk membuat alat ukur yang dapat mengukur nilai intensitas cahaya (lx), nilai PPFD (µmol/m²/s), dan rentang warna. Pada penelitian ini juga membahas korelasi antara intensitas cahaya (lx) dengan PPFD dimana tiap masing masing warna memerlukan persamaan nilai konversi tersebut untuk diprogram pada sensor. Adapun persamaan konversi nilai intensitas cahaya (lx) ke PPFD pada LED warna merah yaitu Y = 0,038x – 0,028, LED warna putih Y = 0,019x + 0,0167, LED warna biru Y = 0,1294x – 0,4031, LED warna hijau Y = 0,0075x + 0,0121, dan LED warna kuning Y = 0,0112x – 0,0029. Dalam penelitian ini menggunakan beberapa metode diantaranya metode penelitian deskriptif, korelasional, kuantitatif dan studi literatur. Dimana output pada penelitian ini berhasil dibuatnya alat PPFDetector dan sistem monitoring berbasis aplikasi android sebagai media monitoring jarak jauh

The process of photosynthesis plays a crucial role in plants. There are indicators involved in this process, one of which is light intensity. Regarding illumination itself, several parameters need to be considered: quality, intensity, and photoperiod. Light quality relates to Photosynthetically Active Radiation (PAR), which is the range of light within the electromagnetic spectrum, while intensity pertains to the amount of light received per unit area, typically expressed as Photosynthetic Photon Flux Density (PPFD). Inappropriate lighting conditions can have negative impacts on plant growth. Therefore, there is a need for a system to monitor light spectrum quality to optimize the photosynthesis process. This research focuses on developing a device capable of measuring light intensity values (lx), PPFD (µmol/m²/s), and color spectrum. The study also investigates the correlation between light intensity (lx) and PPFD, requiring conversion equations programmed into the sensors for each color. The conversion equations for light intensity (lx) to PPFD are as follows: red LED (Y = 0.038x – 0.028), white LED (Y = 0.019x + 0.0167), blue LED (Y = 0.1294x – 0.4031), green LED (Y = 0.0075x + 0.0121), and yellow LED (Y = 0.0112x – 0.0029). The research employs various methods including descriptive, correlational, quantitative approaches, and literature review. The output of this study includes the development of the PPFDetector device and an Android-based monitoring system for remote monitoring.
