Abstract

Solar panels are the main component of solar power plant. In the Solar panels, conversion of solar energy into electrical energy are done. The results of the electrical energy produced by solar panels depend on the amount of solar intensity received by the solar panels. In addition, the working temperature of solar panels is also crucial. The ideal solar panel temperature is 25 C, which means that the solar panel will work optimally at that condition. When the temperature rises, the solar cell performance will decrease. This study aims to design a solar panel cooling system with active and passive methods using a way of flowing water over the surface of the solar panel and adding wet coconut coir on the back of the solar panel. The purpose of providing this treatment is to keep the surface temperature of the solar panel from overheating. This study uses a 100 WP solar panel and the results obtained that the average power generated is 69 W with an average voltage value of 15.47 V and an average current of 4.5 A. The performance 100 WP solar panels increased 24% of the reference solar panels being compared

Abstract

Ujungmanik Village has a eucalyptus oil distillery with essential oil products produced of 100 kg per year. The problem is that the waste from the eucalyptus oil distillation, in the form of twigs and leaves from the eucalyptus oil distillation, accumulates and reduces the production area. The purpose of this study was to design a eucalyptus waste compost fertilizer packaging machine with the addition of a load cell sensor. The method used in making this compost fertilizer packaging machine is a PLC control system for the packaging section and ESP8266 is used to control the load cell sensor for weighing during the packaging process. The test results show that the eucalyptus oil distillation waste compost fertilizer packaging machine based on the PLC control system is capable of packaging 1000-gram organic fertilizer by the load cell sensor and is capable of packaging 10 plastic bags. Based on the monitoring results through the Blynk application, the packaging has an average value of 994.1 grams and an error percentage of 2.1%

Abstract

Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.
