One of the renewable energies in Indonesia is solar energy. The geographical condition of Indonesia, which is a tropical country, is one of the advantages it has for applying solar energy. The Indonesian government is gradually regulating the population system for Solar Power Plants (PLTS). The resident system is in demand because of the advantage that it can be connected to the PLN grid and used as an energy reserve. The installation of rooftop PLTS both in government buildings and on the roofs of houses has now become a common trend in the community as a form of participation in the use of New and Renewable Energy (EBT). Before installing PLTS Roofs, it is necessary to determine in advance how much capacity will be installed. This is also related to the community's question, what is the percentage of electricity costs if PLTS roofs are installed in bulk. These designs and calculations are generally carried out with the help of simulations. To discuss these problems, in this article, we will discuss a simulation of the potential for electrical energy generated from rooftop solar power plants in Cilacap Green Smart Living housing. The simulation was carried out with the help of the SolarGIS PV lunar device. Analytical calculations are carried out by software based on input of regional location and solar irradiation. SolarGis will calculate the daily output power generated by the rooftop PV mini-grid and the average monthly and yearly power. The simulation results show that one house with a daily energy requirement of 13 kWh by installing a rooftop PLTS with a capacity of 3 kWp, the demand for electrical energy imported from the PLN network to the house is only 7.8% in one year.

Air merupakan sumber daya alam yang menjadi salah satu kebutuhan utama dalam kehidupan dan sampai saat ini belum ada senyawa lain yang dapat menggantikannya. Sulitnya mendapatkan air yang berkualitas saat ini masih menjadi problem di beberapa daerah. Masyarakat yang memanfaatkan sumur sebagai sumber kebutuhan air pun terkadang masih mengalami masalah pada kualitas air yang dihasilkan sumur tersebut. Air yang belum layak digunakan khususnya dikonsumsi harus diproses terlebih dahulu, misalnya proses filtrasi. Penelitian ini merancang bangun sebuah sistem penjernih air menggunakan sistem filtrasi yang dapat secara otomatis memfiltrasi secara berulang jika air hasil filtrasi masih melebihi batas nilai kekeruhannya. Sistem filtrasi menggunakan bahan pipa PVC sebagai tabung reaktor filtrasinya dan beberapa bahan penjernihnya yaitu karbon aktif, pasir manganese dan kapas. Sistem penjernih dilengkapi dengan sistem monitoring yang dapat menampilkan nilai kekeruhan air melalui aplikasi Blynk. Beberapa perangkat elektronik yang digunakan yaitu esp32 sebagai kontroler, sensor turbidity untuk mengukur kekeruhan air, sensor ultrasonik untuk mengukur level air pada bak penampung serta pompa DC untuk mengalirkan air dari bak penampung ke reaktor filtrasi. Berdasarkan pengujian sistem filtrasi, menunjukkan bahwa sistem penjernih dapat menjernihkan air dengan tingkat penjernihan sampai dengan 47,56 %. Status air yang diproses filtrasi dapat dimonitoring melalui aplikasi Blynk sesuai dengan perancangan. Informasi bak penampungan air dan nilai kekeruhan air dapat ditampilkan pada aplikasi Blynk dengan baik.

Banjarwaru Village is located in Nusa Wungu District and has several hamlets connected to the main road as access to transportation facilities. The lack of street lighting hampers the activities of village residents, especially at night. Road points that do not have public street lighting are far from residents' homes, so they cannot use PLN electricity sources. Seeing the conditions explained above, the need for technology with energy sources that utilize renewable energy such as solar power to supply power to public street lights has been widely implemented. Making street lights with a solar power supply with the application of modern technology is the main priority in this community service activity. The main target objective of this Community Service is the Public Street Lighting Program through the manufacture of street lights with power supply from solar energy. The implementation method in this service is through observation and experiments in the field in the process of designing and manufacturing public street lights and handing over technology transfer to the community. The results of making public street lights with solar energy supply using Arduino Mega which functions to receive data from the LDR sensor and is continued with testing battery charging with solar power.

Some things that must be considered to improve the work of an induction motor are the rotational speed of the motor which is expected to continue to be increased, torque that can meet the load, and higher efficiency. Multilevel inverters will play an important role in converting DC energy from battery sources into AC electrical energy. This study aims to create a single-phase induction motor speed control system with an Arduino Mega-based Multilevel inverter. External input in this study uses a normally close push button with two initializations, namely the Up and Down push buttons. The push button functions as an induction motor speed control with speed conversion in the form of a percent parameter. Parameters will appear on the LCD display for every change that occurs. The test results show that the induction motor will start rotating at a percentage of 20%, namely at a speed of 1631.8 RPM, then Up to 40% at a speed of 2260.2, Up again to 60% at a speed 3261.8 RPM, and at 80% speed it produces 4163.8 and the highest speed reaches 5241.4 RPM with a speed percentage of 100%. The rotational speed of the motor can be displayed on the LCD display in the form of a digital display.

Solar panel systems are widely used to meet energy needs at this time. Solar panels have optimal power for 4 hours, namely 10:00 to 14:00. but this is still said to be not optimal if the angle of the static solar panels does not follow the movement of the sun. This can also be caused by weather factors that are covered in clouds. Previous research conducted by Tri Wahyu Ardianto used mirror reflectors but was not equipped with sensors and data storage. Based on this, to optimize solar panel energy, a flat mirror reflector design for solar panels has been made, equipped with four flat mirror reflectors on each side to form a large square. The solar panel is placed in the middle between the four flat mirrors. In this study, the measurement of electric power was carried out by carrying 3 variable angles for reflector positions, namely 0°, 60°, and 70°. The decision of the three reflector positions is made to find out the ratio of the maximum output power values. This system is also equipped with current, voltage, and light intensity sensors. The results show that the maximum output power of solar panels is shown at the reflector position of 60° with an average power output of 19.70 Watt followed by a reflector position of 70° with an average output power of 19.18 Watt and finally the reflector position is 0° with an average output power value of 14.87 Watt.
