Abstract

Pengenalan energi surya kepada anak terlantar penting dilakukan agar kelompok marginal tidak hanya menjadi penerima bantuan, tetapi juga memperoleh pengalaman belajar teknologi yang produktif. Kegiatan pengabdian ini bertujuan memperkenalkan prinsip kerja panel surya dan rangkaian listrik sederhana melalui mini project sains bagi anak binaan Komunitas Peduli Anak Jalanan di titik penampungan Telkommas, Kecamatan Tamalanrea, Kota Makassar. Kegiatan dilaksanakan pada 15 September 2024 dengan melibatkan 10 anak usia sekolah dasar. Metode kegiatan menggunakan pendekatan product-based learning melalui demonstrasi, perakitan produk, pendampingan kelompok kecil, evaluasi fungsi produk, dan diskusi potensi nilai jual. Produk utama yang dibuat adalah kipas angin mini tenaga surya, sedangkan produk pendukung berupa lampu hias LED berbasis rangkaian listrik sederhana. Hasil kegiatan menunjukkan peserta mampu mengikuti proses perakitan, memahami bahwa cahaya dapat diubah menjadi energi listrik dan gerak, serta menunjukkan antusiasme tinggi ketika produk berhasil berfungsi. Kegiatan ini bermakna sebagai model pemberdayaan berbasis pendidikan IPA karena menggabungkan literasi energi terbarukan, keterampilan teknis sederhana, dan kesadaran awal kewirausahaan.

Abstract

Water spinach (Ipomoea reptans Poir.) is a leafy vegetable that is highly nutritious and has the potential to be cultivated using a hydroponic system with environmentally friendly organic fertilizers. This study aims to determine the effect of fermentation duration and the combination of goat manure biofertilizer with AB Mix on the growth of water spinach (Ipomoea reptans Poir.) in a hydroponic system. The biofertilizer was fermented for 7, 14, and 21 days, then applied to various treatment combinations. The results showed that 7-day fermentation produced the best results in the P125AB75 treatment, with an average leaf width of 1.60 ± 0.56 cm and leaf length of 5.37 ± 1.05 cm. Fourteen-day fermentation produced optimal growth in the P20AB100 treatment with a leaf width of 2.13 ± 0.15 cm and a leaf length of 5.35 ± 0.59 cm. Meanwhile, 21 days of fermentation showed the most significant results in the P30AB100 treatment with a leaf width of 2.30 ± 0.10 cm and a leaf length of 6.45 ± 0.46 cm. Increasing the fermentation period was proven to improve nutrient availability, enrich active metabolites, and stabilize organic compounds, thereby supporting more optimal vegetative growth of water spinach compared to pure manure. Thus, liquid biofertilizer from 21-day fermentation, especially in the P30AB100 combination, is the best treatment for enhancing water spinach growth in hydroponic systems.
