Abstract

The provision of adequate clean water is a form of fulfilling the basic needs of the community, which is very important for supporting good health and quality of life. Kelindang Atas Village still has problems in the management and rehabilitation of domestic water channels. This community service initiative aims to optimize clean water supply by assisting the community in developing a Cost Estimate Plan (CEP) for the rehabilitation of domestic water supply systems. The methods used include observing the condition of water supply systems, conducting outreach on CEP development, and facilitating group discussions with village residents as partners. The results of the community service initiative demonstrate an increase in community understanding of the planning and budgeting processes for rehabilitation, as well as the development of a realistic and field-appropriate RAB. Resulted in a 60% increase in budgeting accuracy as measured by alignment with field conditions. Active community involvement in the RAB development process through guidance is the key to the success of optimizing clean water supply in Kelindang Atas Village.

Abstract

The use of DC distribution is considered more efficient than AC in off-grid PV systems because it reduces energy conversion losses, especially in loads such as LED lights. A comparative study of DC and AC LED lighting is needed to improve the efficiency of offgrid PV systems. This study compares the performance of DC and AC LED bulbs for lighting a 12 V off-grid PV system. Testing on a 12 V off-grid PV system was carried out by collecting data in the form of DC power from a 12 V VRLA battery and light intensity (lux) produced by samples of DC and AC LED bulbs with nominal power of 10 W, 20 W, and 30 W, with uniform technical specifications. The results of the study indicate that DC LED bulbs are more efficient than AC LED bulbs both in power consumption from off-grid PV systems and in producing light. Thus, lighting in a 12 V off-grid PV system is more efficient using DC LED bulbs.
