The widespread use of smartphones in public places has driven the adoption of power banks as a solution for power needs. However, power banks have several drawbacks. To address these needs in public places, charger station systems have been widely implemented, including solar panel-based charger stations as their power source. These developments have also extended to commercial applications, allowing the use of charger station facilities in public places to be subject to specific charges. In this study, a solar charger station system with coin-operated payment for electricity was developed. Additionally, for system security, a feature was added to limit the current flow to the load to a specific amount. The charger station was built using several components, including solar panels, solar charge controllers, and batteries, which are integrated to produce electricity. An inverter is used to convert DC current into AC current, which is then connected to electrical terminals via a solid-state relay switch. Arduino Uno is used to control the electrical connection from the inverter to the terminal through the solid-state relay based on data from the coin acceptor and the PZEM-004T sensor. An LCD is also used to display information required by the users. The test results showed that the solar charger station system could successfully charge smartphones using 1,000-rupiah coins with a 100% success rate. With a rate of 1,000 rupiahs per 40Wh, the charger station system can disconnect the power supply to each load after consuming 40Wh of electricity. Additionally, the system is capable of disconnecting the load when the attached load exceeds 40W.

Electric scooters rely on batteries to power BLDC motors, which are traditionally recharged through the household electricity grid. However, alternatives like solar energy are being explored to reduce dependency on conventional power sources. A challenge arises due to the discrepancy in voltage compatibility between standard solar panels and scooter batteries. Typically, a 36 V scooter battery requires a higher voltage input than the 18 V output of a single solar panel. This requires modifications to align solar cell design with battery voltage requirements. This study implements a PZEM-015 sensor for monitoring battery energy consumption. The contribution of this study is twofold: to develop and optimise solar cell modification for effective battery charging and to assess battery consumption concerning speed and travel duration. Testing reveals that a series circuit modification yields an average voltage of 39.2 V and an average current of 0.55 A, resulting in 21.8 Wp of power output. Analysis of scooter performance indicates that maintaining speeds between 4.16 m/s and 5.55 m/s significantly extends travel time and conserves battery energy. These findings highlight the potential of modified solar PV in enhancing electric scooter efficiency and sustainability.

Upaya untuk meningkatkan efisiensi turbin adalah dengan memperbesar torsi turbin dengan cara menambah berat sudu turbin. Torsi merupakan energi atau momen gaya yang dikeluarkan sebuah sistem untuk menghasilkan energi kinetik dalam bentuk gerakan rotasi poros turbin yang muncul saat turbin bergerak. Turbin yang diuji adalah turbin kaplan dengan jumlah sudu 4, 5 dan 6 buah dan berat turbin 6,25 N dan 6,75 N sebagai pemicu meningkatnya torsi turbin. Untuk mengetahui berapa besar efisiensi kincir, maka dipasang sebuah sistem pembebanan yang dihubungkan dengan pully pada porosnya turbin. Hal tersebut dilakukan untuk mengetahui daya mekanik turbin dari energi kinetik yang menumbuk sudu turbin melalui putaran porosnya`.Hasil menunjukkan bahwa torsi turbin yang besar dapat mempengaruhi gerak rotasi poros turbin dan kecepatan anguler walaupun beban yang diberikan cukup besar. Untuk berat turbin 6,75 N dapat menghasilkan daya lebih besar dibandingkan dengan berat turbin 6,25 N terutama pada jumlah sudu 5 buah. Efisiensi turbin dapat mencapai 36 % pada putaran 546-488 rpm dengan debit aliran 0,0279 m3/s, pada berat turbin 7,25 N dan jumlah sudu 5. Hal tersebut karena rugi-rugi yang ada pada sudu-sudu turbin seperi rugi-rugi mekanik akibat gesekan terhadap poros, fully dan rugi energi kinetik pada saat berputar cukup kecil.

Indonesia memiliki potensi besar dalam pemanfaatan energi surya karena letaknya yang strategis di garis khatulistiwa. Panel surya mengonversi radiasi matahari langsung dengan efisiensi puncak sebesar 9-12%, sementara lebih dari 80% radiasi matahari tidak dapat dikonversi menjadi energi listrik. Salah satu faktor yang mempengaruhi efisiensi panel surya adalah suhu permukaan panel yang tinggi, yang menyebabkan penurunan daya keluaran. Penelitian ini bertujuan untuk merancang dan menguji sistem pendingin panel surya menggunakan fluida air sebagai media pendingin guna mengoptimalkan daya keluaran dan mencegah kerusakan akibat tingginya intensitas radiasi matahari. Sistem pendingin ini dirancang dengan mengalirkan fluida air melalui pipa spiral di belakang permukaan panel surya berkapasitas 50 Wp. Hasil pengujian menunjukkan bahwa suhu permukaan panel tanpa pendingin berkisar antara 40°C hingga 49°C. Sementara itu, penggunaan pendingin air aquades menurunkan suhu permukaan panel menjadi 34°C hingga 38°C, dan penggunaan air yang dicampur dengan es batu lebih efektif menurunkan suhu menjadi 27°C hingga 30°C. Tegangan rata-rata pada panel tanpa pendingin adalah 19,9 V dengan daya keluaran sebesar 19,59 W. Dengan penggunaan pendingin air aquades, tegangan meningkat menjadi 20,4 V dengan daya keluaran sebesar 20,48 W, sedangkan penggunaan air campuran es batu menghasilkan tegangan sebesar 20,5 V dan daya keluaran sebesar 20,88 W. Penelitian ini membuktikan bahwa penggunaan sistem pendingin berbasis air aquades dan es batu efektif dalam menurunkan suhu permukaan panel surya dan meningkatkan daya keluaran panel surya. Indonesia has great potential for solar energy utilization due to its strategic location along the equator. Solar panels convert direct solar radiation with a peak efficiency of 9-12%, while over 80% of solar radiation cannot be converted into electrical energy. One of the key factors affecting the efficiency of solar panels is the high surface temperature, which leads to a decrease in power output. This study aims to design and test a cooling system for solar panels using water as the cooling medium to optimize power output and prevent damage caused by high solar radiation intensity. The cooling system is designed by circulating water through a spiral pipe behind the surface of a 50 Wp solar panel. The test results show that the surface temperature of the panel without cooling ranges from 40°C to 49°C. Meanwhile, the use of distilled water as a cooling fluid reduces the surface temperature to between 34°C and 38°C, and the use of water mixed with ice is more effective, reducing the temperature to between 27°C and 30°C. The average voltage of the panel without cooling is 19.9 V, with a power output of 19.59 W. With the use of distilled water, the voltage increases to 20.4 V, with a power output of 20.48 W, while the use of water mixed with ice yields a voltage of 20.5 V and a power output of 20.88 W. This research demonstrates that the use of a cooling system based on distilled water and ice is effective in reducing the surface temperature of solar panels and increasing their power output.

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.

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 0Â°, 60Â°, and 70Â°. 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 60Â° with an average power output of 19.70 Watt followed by a reflector position of 70Â° with an average output power of 19.18 Watt and finally the reflector position is 0Â° with an average output power value of 14.87 Watt.

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. The installation of the LDR sensor will help the efficiency of the lights because it will control the lights to turn on automatically. The results of the manufacture of public street lights also provided assistance and training to the Banjarwaru Village community regarding how the equipment works and the repair process if problems arise in the future.
