Abstract

The global energy shortage, especially in developing countries, drives the search for alternative energy sources such as solar power, which is one of the cleanest energy sources. This research discusses the comparison of efficiency between solar PV fixed, single-axis solar trackers, and dual-axis solar trackers. The method used is a survey of the literature of multiple studies that only analyzes the efficiency of solar PV using different tracking devices. The efficiency data is normalized based on location factors and light intensity for a fair comparison. The results show that fixed solar panels are stationary and simple, serving as a baseline with 100 % efficiency. Single-axis panels track the sun horizontally, boosting efficiency by 25.6 % but with moderate complexity due to motors and controls. Dual-axis panels track the sun both horizontally and vertically, increasing efficiency by up to 50 % but with the highest complexity due to more moving parts and dual-axis control systems.

Abstract

Ikan Patin (Pangasianodon hypophthalmus) merupakan komoditas utama perikanan di Kelurahan Rumbai Bukit. Permasalahan yang sering dialami pelaku budidaya ikan patin adalah berkurangnya air di musim kemarau dan menurunnya kualitas air akibat penumpukan zat pengotor. Untuk mengatasi permasalahan ini, dilakukan penyuluhan pengaruh penggunaan mesin pompa dan filter air terhadap peningkatan kualitas air kolam. Kolam ikan patin terdiri dari 3 kolam yang tersusun secara seri, dengan perbedaan elevasi 4-7 Mdpl. Pompa dengan debit rata-rata 0,44 m/detik digunakan untuk menarik air kolam nomor 3 ke kolam nomor 1 masuk ke instalasi filter air.  Bahan filter disusun secara vertikal dalam drum bervolume 120 L, dari dasar ke atas adalah batu bata, batu zeolite, batu kerikil, palm fiber/ijuk, busa filter, batu kerikil, batu bata, dan busa filter. Pipa inlet air dari bawah drum filter dan pipa outlet membawa air tersering ke atas dan meluncur ke kolan nomor 1dan menuju ke kolam nomor 2. Perubahan kualitas air kolam yang terjadi sebelum dipasang pompa dan filter adalah sebagai berikut, kondisi pH berkisar 6,5-6,7 meningkat setelah difilter menjadi 7,2-8,4, TDS yang sebelumnya 66-70 ppm menurun menjadi 58-62 ppm setelah difilter, dan suhu air berkisar 27-34⁰C. Peningkatan mutu kualitas air sudah sangat sesuai untuk pemeliharaan ikan patin.
