Abstract

Irigasi yang efektif sangat penting untuk memenuhi kebutuhan air tanaman sekaligus mencegah penguapan berlebih dan kekurangan air. Praktik konvensional seringkali menyebabkan pemborosan air dan pupuk sehingga menurunkan efisiensi produksi pertanian, Kegiatan ini bertujuan untuk menerapkan sistem drip irrigation berbasis Internet of Things (IoT) dan energi terbarukan meningkatkan efisiensi penggunaan air dan nutrisi pada budidaya kubis di Kelompok Tani Bangkit Merbabu. Sistem ini mengintegrasikan sensor kelembapan tanah, suhu, dan kelembapan udara yang terhubung ke mikrokontroler untuk melakukan monitoring dan kontrol otomatis. Irigasi dan fertigasi dijadwalkan sesuai kebutuhan tanaman dengan mode otomatis. Hasil penerapan menunjukkan bahwa sistem fertigasi tetes berbasis IoT mampu meningkatkan efisiensi waktu kerja sebesar 80%, dibandingkan metode konvensional, dengan penghematan air mencapai 40%. Penerapan sistem ini menunjukkan potensi signifikan dalam mengoptimalkan sumber daya pertanian, meningkatkan produktivitas, serta mendukung penerapan pertanian presisi dan berkelanjutan berbasis energi terbarukan.

Abstract

This work presents an enhanced ray tracing-based modeling framework to optimize bifacial photovoltaic energy generation and crop productivity within greenhouse environments. The proposed framework integrates a ray tracing-based optical and electrical model to simulate light dynamics and energy generation within greenhouse structures. The optical model incorporates Uniform Distribution of rear-irradiance (UF) and Non-Uniform Distribution of rear-irradiance (NUF) principles to simulate irradiance distribution, shading, and reflection, using Light Saturation Point (LSP) and Photosynthetically Active Radiation (PAR) measurements. The electrical model estimates energy yield using the LambertW function based on incident and transmitted light through photovoltaic arrays. Five types of greenhouse structures using plastic and SG80 materials are analyzed to assess their impact on system performance under various conditions. The evaluation showed that integrating bPV increased rear-side energy captured by 25-30%. The optimal configuration was achieved by combining a plastic cover with a checkerboard pattern, resulting in up to 5% higher performance than the 35° tilt setup and offering enhanced light distribution uniformity. Although the average soil irradiance of 170.801 W/m² slightly exceeded the light saturation threshold of 164.7 W/m², it remained within a safe range that supports efficient photosynthesis without causing photoinhibition.
