Indonesia is a tropical country located on the equator. The average intensity of solar radiation in Indonesia is 4.8 kWh/m2. This makes Indonesia a country with new and ren ewable energy potential, one of which is solar panel technology. The first step that must be done in the process of installing solar panels in a place is to analyze the potential of solar energy. In this study, an analysis of the potential of solar energy as a new renewable energy source has been carried out at Budi Luhur University, North Petukangan, South Jakarta. Based on the research results, the maximum photovoltaic efficiency that can be achieved is 21.45%. During the day, the efficiency of the solar panels increases along with the ncrease in the value of the voltage obtained. However, the higher the panel temperature, the lower the efficiency of the solar panel. Therefore, a cooling system is needed to anticipate this.

The laboratory has information that must be updated frequently to provide students with information regarding the presence of laboratory assistants. Therefore, in this study, digital signage will be used as an information medium that can display laboratory assistant presence data in real-time. Through digital signage, laboratory assistant presence information can be displayed digitally and accurately. The initial step of the program is to initiate the database. After the E-KTP is attached to the RFID, the database will check whether the identity on the card is recognized or not. If the card is registered on the attendance form, it will be displayed on digital signage. Based on the test results, the use of digital signage as an information board based on RFID as a method of identifying the presence of laboratory assistants has given good results. This system can display real-time and accurate attendance information through digital signage. In addition to testing the duration of the RFID reading when exposed to obstacles in the form of plywood and acrylic and when not exposed to obstacles, it shows variations in reading duration depending on the surrounding environment of the RFID reader. Furthermore, Quality of Service (QoS) testing was carried out, which showed very good results according to TIPHON standards. The test results show the lowest delay in the morning using a tethering network with a value of 11 ms and the highest throughput in the morning using a tethering network with a value of 736.649 bits/s. Packet loss and jitter are 0 each time.

A flood is a natural disaster that occurs due to high rainfall and causes the overflow of rivers or streams that cause many losses to humans and can be an impact that causes electrical short circuits. This can certainly lead to harm such as injury, injury, even loss of life. In certain areas, many are still affected by flooding, especially in Jakarta and its surroundings. Many measures taken to deal with flooding have not been sufficiently effective, but few have cared for their own safety in the face of the effects of flooding. In this final assignment he designed a prototype model of an automatic power cutting system for flood disaster response homes. Designed on a 1:10 scale system with a height of actually 200 cm. Prototype models are made for simulation testing to facilitate the system in testing. The system consists of an ultrasonic sensor, an MCB, a servo, a traffic light indicator in the form of a light, a buzzer in the form of a sound, and an LCD 16x2 as a display of the sensor readings. The process in the system with the reading of the distance of the water surface uses the HC-SR04 ultrasonic sensor to produce a high value of water with the calculations on the program. And the calculation for the accuracy of the ultrasonic sensor readings uses the RMSE (root mean square error) formula and gets an RMSE value of 0.20 - 0.95 Cm where 0.20 Cm is the lowest RMSE value at 15 Cm water height and 0.95 Cm is the highest RMSE value at 10 Cm water height. The working principle of the system is to read the distance of the water surface to produce a high value of water, the high value of water is divided into 3 statuses, namely safe at a height of 0-7 Cm, alert at a height of 8-14 Cm, and flooding at a height of 15 Cm. At a height of 15 Cm and declare the flood status results that cause automatic power breaks.. Keywords : Fresidential flood, ultrasonic sensors, prototype model

ABSTRAKSalah satu faktor yang dapat mempengaruhi efisiensi panel surya adalah suhu pada modul panel surya. Efisiensi panel surya akan menurun seiring dengan naiknya suhu panel surya. Oleh karena itu, dibutuhkan suatu mekanisme pendinginan pada sistem panel surya untuk dapat meningkatkan efisiensi panel surya. Pada penelitian ini, dirancang sebuah sistem pendinginan panel surya dengan metode penyemprotan air dan pengontrolan suhu air. Jika suhu telah mencapai 40oC, pompa yang terdapat pada bak penampungan air akan bekerja mengalirkan air ke permukaan panel surya. Dengan demikian, suhu pada panel surya dapat dikontrol agar sesuai dengan set point yang diinginkan yakni di bawah 40oC. Sistem pengontrolan suhu air dengan peltier dan fan dilakukan untuk mengontrol suhu air di dalam bak penampungan air agar tetap berada pada suhu maksimal 39oC. Sistem pendinginan panel surya pada penelitian ini mampu meningkatkan daya keluaran panel surya sebesar 30,19%.Kata kunci: panel surya, pendingin, semprotan air, peltierÂ ABSTRACTThe solar panels efficiency can be affected by the the temperature of the solar panel module. It will decrease as the temperature of the solar panels increases. Therefore, a cooling mechanism in the solar panel system is needed to increase the efficiency of the solar panels. In this study, a solar panel cooling system was designed with the method of spraying water and controlling water temperature. If the temperature has reached 40oC, the pump in the water reservoir will work to circulate water to the surface of the solar panel. Thus, the temperature on the solar panel can be controlled to match the desired set point, which is below 40oC. The water temperature control system with peltier and fan is carried out to control the temperature of the water in the water reservoir so that it remains at the maximum temperature of 39oC. The solar panel cooling system in this study was able to increase the solar panel output power by 30.19% when using the cooling system.Keywords: solar panels, cooling, water spray, peltier
