In agriculture with the hydroponic method of the DFT system (Deep Flow Technique), the circulation of plant nutrients must occur continuously to prevent decay in plants. Along with the many concerns due to the large electricity costs incurred to run the irrigation system for hydroponic plants, the authors hereby design a tool in the form of a submersible pump as a medium for regulating the flow of water in plants by utilizing a 50 WP PV module instead of a source of electrical energy from PLN. The method used in this research is the method of observation, literature study, design, and testing. The results of the 50 WP solar panel-based submersible pump trial show that a circuit connected to a battery at 1M Head tends to produce a stable water discharge, which is an average of 6.03 liters/minute compared to one that is not connected to a battery, which is only 5.28 liters/minute. Furthermore, the resulting water discharge affects the quality of the plants, especially in root length, number of leaves, leaf length, and leaf size. The test results are used as a reference for the comparison of expenditure costs between irrigation systems run using solar cells and those based on conventional (PLN).

Solar energy installations mathematically and visualization using the Solar Global Atlas Software simulation. The data obtained is that the highest energy occurred in the second test with the result of 365.7 Wh with the maximum power generated by solar panels of 93.28 W, battery charging energy of 321.5 Wh with a maximum battery charging power of 76.78 W. Sunhour that occurs is obtained 3.66 h with solar panel efficiency that occurs at 12.8%. The research methods used include quantitative research methods by taking data using measuring instruments using literature studies, simulations and experiments to then be processed using related formulas in the implementation of the research.

Solar energy is a potential solution to meet the electricity needs of TNI AD posts and bases in border areas. However, conventional solar energy systems have limited efficiency because they can only absorb sunlight from one direction. The efficiency of solar energy systems can be improved by using a dual-axis tracking system equipped with a LDR sensor. The LDR sensor is used to detect the direction of sunlight. The change in the LDR sensor resistance due to the change in the intensity of light that hits it is then processed by a microcontroller to move the solar panel in the appropriate direction. Based on the results of testing, the dual-axis tracking system with an LDR sensor significantly increases the power generated compared to conventional solar energy systems. At the peak of performance during dynamic testing at 12:00 pm, the total power reached 2,196 W, while the static test reached a total power of 1,311 W. Therefore, the dual-axis tracking system with an LDR sensor can be a more optimal choice to improve the performance and efficiency of solar energy systems in generating electricity at TNI AD posts and bases in border areas.

Pemanfaatan energi terbaharukan  dalam pertanian ialah matahari yang merupakan energi yang tidak ada habisnya dan dapat dimanfaatkan untuk mensejahterakan masyarakat khususnya dalam lingkup pertanian, Salah satu bentuk pemanfaatan energi terbaharukan di Desa Pontang Legon ialah dalam teknologi yang dapat mengatasi permasalahan para petani konvensional yang sangat bergantung pada cuaca dan iklim disebut juga dengan agrivoltaic namun pemanfaatan energi terbaharukan untuk petani masih belum optimal sebab saat ini masih bersifat sporadis atau  hanya dilakukan oleh beberapa orang atau kelompok masyarakat setempat. Metode yang digunakan dalam pengabdian di Desa Pontang Legon ini ialah observasi, studi Pustaka dan evaluasi. Hasil dari uji pemanfaatan energi terbaharukan melalui agrivoltaic ini sangat baik berdasarkan hasil evaluasi sebab agrivoltaic ini efektif untuk hidroponik   dan meningkatkan efesiensi lahan.
