Abstract

Every life is never separated from the need for water because water is a basic need, especially for humans, both for drinking, bathing, and at the time of pilgrimages to tombstones they the visit. Meanwhile, to get the water, the community lifts it from the nearest water source, namely a healthy water source, which is done manually by drawing water and putting it into a water reservoir. Suppose done enough draining continuously. In addition, to get a power source at the burial site, the community takes electricity from the nearest power source or residents' homes. However, this can be overcome by using an alternative solar power generation system as a driving force for a water pump to lift DC water designed portable to meet water needs. By doing a design using two solar panels of 100watt peak, a solar charge controller with a capacity of 20 amperes and a battery unit with a total of 20Ah able to lift water from the well to a water reservoir 89.034 liters in 8 minutes. The electrical energy required for single use of the water pump is 23.4 Wh, so it is expected to increase the use of time, energy, and the volume of clean water to be more efficient.

Abstract

Tri Sedyo Manunggal Farmer Group in Wukirsari Village, Sleman Regency, Yogyakarta faces challenges in managing agricultural land. The irrigation system is still done manually, while the source of electricity to drive the water pump still depends on PLN electricity and fuel. As a solution, an internet of things is needed that can monitor soil pH, humidity, temperature, and leaf color and can be accessed remotely. The irrigation system is automatic, and the power source is obtained from solar panels to drive the water pump to lift water from the well to the output pipe. Four solar panels are used, each panel has a power of 230 watts peak, a solar charge controller with a capacity of 50 amperes, two soil pH sensors, two humidity sensors, two temperature sensors, and two color sensors. The battery used is a 12-volt Valve Regulated Lead Acid (VRLA) type with a capacity of 100 Ah. A water pump with a capacity of 300 watts with a water discharge of 47 liters per minute can meet the water needs of 1 ha of agricultural land in about 3-4 hours. The maximum electrical power generated by solar panels under maximum sunlight conditions is 920 watts peak, with a maximum current of 11.79 amperes and a maximum voltage (Vmp) of 19.5 volts. Then the solar panel will charge the battery in an empty condition for about 90 minutes in 80% sunlight efficiency conditions.
