Abstract

The aim of this research is to design an eletrtic circuit system using solar panel to meet the needs of electric pumps of hydroponic irrigation system. This research may develop the knowledge that applied to application of solar panel system and to modify hydroponic planting systems by using solar panels to regulate the air circulation in plants. This study used an experimental method which conducts in Kelurahan Nyiur 1, at Wenang village. The data was obtained and analyzed descriptively. The results of the application of solar panels as a source of electricity for the system consist of several main components, namely the charger controller, relay, power supply, ats initial dc laptop, timer controller and 12 volt dc water pump. The result shows that solar panel application as an electric source of hydroponic system works well and so does the works of timer controller as water pump controller. Keywords: Solar panels, charger controller, Hydroponics, Deep Flow Technique Abstrak Tujuan penelitian ini adalah mendesain sistem rangkaian listrik menggunakan panel surya untuk kebutuhan listrik pompa irigasi sistem hidroponik. Manfaat penelitian ini yaitu mengembangkan ilmu pengetahuan yang diterapkan pada aplikasi sistem panel surya dan memodifikasi sistem tanam hidroponik menggunakan panel surya agar sirkulasi air pada tanaman bisa terkontrol. Penelitian ini mengunakan metode eksperimental yang dilaksanakan di Kecamatan Wenang Kelurahan Nyiur Lingkungan 1 dimana data yang didapat dianalisis secara deskriptif. Hasil aplikasi panel surya sebagai sumber listrik sistem terdiri dari beberapa komponen utama yaitu charger controller, relay, power supply, ats dc awallaptop, timer controller dan pompa air dc 12 volt. Hasil penelitian menunjukan aplikasi panel surya sebagai sumber listrik sistem hidroponik dan cara kerja timer controller sebagai pengontrol pompa air, dapat bekerja dengan baik.

Abstract

Food security remains a major challenge in developing countries, particularly in relation to the vulnerability of food consumption among low-income households. Rice plays a central role in Indonesia’s food system as the main staple food and a key determinant of food availability and access. However, increasing rice production does not necessarily guarantee adequate food consumption if economic access to food remains limited. This study aims to analyze the relationship between rice production, food access factors, and the prevalence of food consumption inadequacy as an indicator of food poverty vulnerability. The analysis employs a Two-Stage Least Squares (2SLS) econometric approach using secondary data from the Indonesian Central Bureau of Statistics and related institutions for the period 2018–2023. The first-stage estimation shows that paddy harvested area is the most significant factor influencing rice production, highlighting the importance of land utilization in determining food availability. In the second stage, the number of poor population emerges as the most influential factor affecting food consumption inadequacy, while income per capita and average rice production contribute to reducing the prevalence of inadequate food consumption. These findings indicate that food insecurity is driven not only by the availability of staple food but also by households’ economic ability to access food. Therefore, strengthening food security requires integrated policies that simultaneously support agricultural production, protect agricultural land, and reduce poverty to improve household access to food
