Abstract

Solar Power Plants (PLTS) are electrical power generators that convert solar energy into electrical power. One of the companies engaged in electricity generation is PT. Brilliant Renewable Infrastructure. The problem that often occurs in PLTS is zero power in the combiner box. Zero power is a problem that often occurs which causes the energy produced by the PV module to not be optimal. The aim of this research is to analyze the causes of zero power in the combiner box. One way to find out the factors causing zero waste is to use a Problem Tree. Problem Tree is a methodology/technique used to identify the reasons for a problem. The results showed that the factors causing zero power in the combiner box were three causes, namely the cable gland installation was not tight enough, the DC cable was bitten by rats and the strings were not functioning. The impact of these 3 types of damage can cause zero power so that no electrical voltage is generated

Abstract

Downtime is a condition in which the machine stops operating not on scheduled stops but due to a disturbance that occurs on the machine, so the machine will be idle until the machine has been repaired or is not in a state of disturbance. Downtime is when production equipment is not functioning due to a sudden inspection and repair of damaged equipment. Elevators can raise the material to a height of up to 50 meters; the capacity can reach 50 ????3/hour. The construction can reach a vertical position. The working principle of this tool is to move the material vertically by placing the material in buckets which are linked by a chain or belt at a certain distance which rotates on the pulley so that the bouquet can move vertically. This study uses the tree diagram method to analyse downtime problems by applying the 5 M + 1E technique.

Abstract

The problem of stunting in West Nusa Tenggara (NTB) remains a serious concern despite a significant decline in stunting rates. Despite this considerable decline, NTB has yet to reach the national target of 14%. There is still 10.6% left to achieve to meet the national target. Stunting in NTB is caused by chronic, recurring malnutrition, especially in animal protein. Therefore, to meet these nutritional needs and increase children's appetite, innovations in stunting management are needed, one of which is creating contemporary foods such as dimsum siomay. Training on making dimsum siomay using chicken and shrimp as raw materials was provided to the Family Welfare Empowerment (PKK) group in Maman Village, Sumbawa Regency, to improve the knowledge and economy of its members, and to reduce stunting rates. The training method used was the Participatory Rural Appraisal approach, which included the delivery of materials and hands-on practice in making dimsum siomay. A review of the training activities was conducted after the training, aiming to evaluate the effectiveness of the training in improving the knowledge, skills, and awareness of the PKK women's group in Maman Village in developing culinary businesses. The evaluation results showed a significant increase in the knowledge, skills, and caring attitudes of PKK members after the training. The training also raised PKK members' awareness of developing independent and sustainable culinary businesses. The training's effectiveness rate was 45%, categorized as quite effective in empowering the PKK women's group economically, and can serve as a model for other community empowerment programs.
