Abstract

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).

Abstract

PT. Sejin Lestari Furniture is a company engaged in the production of furniture such as doors, tables, chairs, cabinets, bookcases and other interior equipment. As one of the companies that have succeeded in producing finished goods in large quantities, PT. Sejin Lestari Furniture relies on the help of an electric motor at every stage of its production, including one of the wood pellet production machines, namely the biofuel pelletizer molding machine which has four different types of motors. In order to work optimally, electric motors need a protection system that can protect them from threats. In this study, the protection system used is Thermal Overload Relay (TOR) which functions as an overload controller so that the electric motor is not easily burned or damaged. In this case, the TOR must be adjusted according to the capacity of each induction motor so that when an overload occurs, the TOR will automatically cut off the current flowing in the motor so that damage can be avoided. The TOR trip standards in this study uses the NEMA (National Electrical Manufactures Association) standard with the method used, namely Research and Development (R&D) where this method is carried out to produce certain products and test the effectiveness of these products. The data collection was obtained through journals and books.
