Abstract

Pertanian tanaman pangan khususnya tanaman padi mempunyai nilai strategis karena merupakan tulang punggung ketahanan pangan dan hajat hidup masyarakat Indonesia. Kabupaten Karawang merupakan salah satu lumbung pertanian yang menyumbang pendapatan perekonomian pada sektor pertanian Jawa Barat. Salah satu faktor yang berpengaruh secara langsung terhadap produktivitas adalah faktor produksi. Tujuan dalam penelitian ini untuk menganalisis perbedaan antara produktivitas padi musim tanam I dan musim tanam II serta perbedaan produktivitas padi pada petani pengguna drone dan petani belum menggunakan di Desa Jayamukti Kecamatan Banyusari kabupaten Karawang. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei untuk mengumpulkan data primer dan data sekunder. Metode penelitian untuk penentuan daerah secara purvosive (sengaja). Sampel dalam penelitian diambil secara Purposive samplingdengan jumlah responden 34 petani padi. Analisis data yang digunakan adalah analisis regresi dengan fungsi produksi Cobb-Douglas. Berdasarkan hasil penelitian, seluruh input produksi secara serentak berpengaruh nyata dan signifikan terhadap produktivitas dengan koefisien determinasi sebesar 81,4% dalam menjelaskan hasil produktivitas. Hasil penelitian menunjukan produktivitas padi musim tanam I lebih besar dibandingkan dengan produktivitas musim tanam II, kemudian produktivitas padi pada petani pengguna drone lebih besar dibandingkan dengan petani belum menggunakan drone.

Abstract

High operating temperature remains a major factor limiting the outdoor performance of solar photovoltaic (PV) modules, particularly in hot climatic regions. This study aimed to determine the solar input and output power and heat of PV modules under natural air-cooling and film water-cooling conditions, to evaluate the corresponding electrical and thermal performance efficiencies, and to compare the relative performance gains achieved by film water-cooling. The experiment was conducted in Sokoto, Nigeria, using two identical PV modules operated simultaneously under natural air-cooling and film water-cooling conditions. Outdoor measurements were taken from 8:30 am to 5:00 pm over five consecutive days. Solar irradiance, voltage, current, module temperature, water temperature, ambient temperature, and wind speed were measured, and the recorded data were used to calculate solar input and output power and heat, as well as electrical and thermal efficiencies. The results showed a clear diurnal variation in solar input, with peak irradiance, input power, and input heat of 605.2 W/m², 484.2 W, and 242.2 J, respectively, recorded at 12:30 pm. The film water-cooled module generally exhibited higher output power and output heat than the naturally air-cooled module during most observation intervals. Electrical efficiency ranged from 6.22% to 10.52% for the film water-cooled module and from 5.90% to 8.52% for the naturally air-cooled module. Thermal efficiency ranged from 18.82% to 70.64% for the film water-cooled module, compared with 19.26% to 41.16% for the naturally air-cooled module. Overall, film water-cooling improved the electrical and thermal response of the PV module under the tested hot-climate conditions, with the strongest benefit observed during periods of higher solar loading.
