<![CDATA[One of the efforts to reduce the transmission of Corona Virus Disease-19 (Covid-19) is by detecting body temperature and disinfection. Detection of body temperature is carried out as an effort to identify sufferers of Covid-19 so it is necessary to prevent them to get together with other people. Manual temperature measurement may cause burnout of staff doing this task and reduced accuracy. Therefore it is necessary to develop an automatic temperature measurement system and display the data be easily observed. Apart from measuring body temperature, another effort to prevent Covid-19 infection is to disinfect the hands. The disinfection process can be done by automatically spraying the disinfectant gel on the hands. The two processes are carried out sequentially, after the body temperature is measured and does not exceed the limit, then the disinfection process is carried out. This procedure is implemented in a gate equipped with two blades with the first blade opening when the body temperature does not exceed the limit, followed by the opening of the second blade after the automatic disinfection of the hand. The procedures are done automatically without touch to minimize physical contact. For the development of the system, an Arduino Mega 2560 microcontroller is needed, 3 MLX90614, 3 HC-SR04 sensors, 3 e18-d80nk, 1 relay, 1 DC motor pump and 2 DC blade actuator motors. The allowable body temperature limit can be determined by manual setting. Operationally this system has been tested and demonstrated the ability to work as desired, including spraying disinfectant gel. For verification of temperature measurements, there was an average deviation of 0.018% from the measurement by the sensor to the temperature measured with thermogun.]]>

<![CDATA[Coastal region normally has sufficient wind power that has not been properly utilized. On the other hand, some places in this region do not have electricity supply from the utility due to some reason. People activity in these areas may need some electricity at least for lighting the area in the evening. For the purpose of generating electricity, a portable power generation is developed to use the wind power and used to supply the power for the light. Wind power plants have so far used propellers with horizontal configurations. In this model, the blades used in propellers have limited dimensions due to mechanical considerations. In addition, the direction of the propeller needs to be directed toward the wind flow, so that a steering wheel and a rotating base are required. To overcome this problem, it is necessary to utilize a number of wind impulse blades placed on the vertical axis. In addition to the expectation to obtain greater thrust, no mechanical equipment is necesary to direct the turbine toward the direction of wind flow. These advantages are expected to increase the output voltage of the generator coupled to it. The generator used in this research is a modified induction motor with some additional magnetic poles to become synchronous generator. The generated power is used to charge a battery which is used to power the light at the night. Small scale generator prototype was developed and tested for coastal locations or other open spaces to obtain wind flow with sufficient power to drive turbine blades.]]>

<![CDATA[This paper presents design and implementation of Automatic Switching for controlling the water level in the reservoir of community water supply. The water supply system is energized by 2 sources i.e. power from utility grid and power generated by photovoltaic panels equipped with energy storage. The switching is based on the reservoir water level and determines the operation of submersible pump. The switching system employs electrode sensors in the water control level where 3 conditions are considered to control motor that drives the pump. The Automatic Switching is connected to Automatic Transfer Switch (ATS) that selects power sources to energize the pump, where it may be from the solar PV supported by storage system or from the grid. The selection is based on the remaining energy saved in the storage, when it is sufficient then it is used to energize the pump. Otherwise, the power from the grid is used to supply the pump. The combination of Automatic Switching and ATS determines when the pump is on and which power is taken to supply the pump. The manual system is complemented in the switching system to enable manual operation when the automatic system fails to work for some reason. The whole system is developed in a panel for easy operation and monitoring. The water level indicator is given in the panel for the purpose of adjusting the pump operation based on water level in the reservoir.]]>

<![CDATA[Harmonic analysis is crucial to maintain the system power quality, especially in photovoltaic panels with load sharing scheme. Previous studies have discussed the impact of harmonic distortion on electric power systems in general, but there is still limited discussion on on-grid photovoltaic panel systems without the load-sharing scheme. Harmonic is a distortion phenomenon of current and voltage that is higher than fundamental frequency. The consumption of nonlinear loads contributes to the rising of harmonic distortion that has a bad impact on the system's power quality. This study aims to analyze and compare the levels of harmonic distortion on on-grid photovoltaic panels with a load-sharing scheme and evaluate the suitability with the IEEE 519-2014 standard. The result of this study shows that the Total Harmonic Distortion (THD) on the current (THDi) in PLN"™s load and network exceeds the limit that is stipulated in IEEE 519-2014. THD current in PLN"™s loads and network is higher than the output current from the on-grid inverter because of the consumption of the nonlinear load. Meanwhile, Total Harmonic Distortion (THD) on the voltage (THDv) in the on-grid inverter, electric network, and load tends to be lower and still within the safe limit. This study is expected to support the implementation of an effective preventive strategy to reduce harmonic distortion on the performance of on-grid photovoltaic panels that will be optimum in the load-sharing scheme.]]>

<![CDATA[This paper examines the performance of photovoltaic panels integrated into the electrical grid in a load-sharing scheme at Darool Ehsan Muhammadiyah Senior High School, Sragen. The study is part of Universitas Muhammadiyah Surakarta's community service program focused on renewable energy development in educational environments. Unlike previous studies relying on simulated data, this research uses real-time primary data from direct measurements of photovoltaic power production and grid electricity consumption over a specific period. The study"™s innovation lies in analyzing the photovoltaic system within a tropical climate-based load-sharing scheme and comparing energy usage when connected to photovoltaic panels versus when disconnected. It also evaluates the impact of reducing solar energy consumption from the grid. The collected data reveal an estimated daily load of 49.89 kWh, with PLN-supplied energy consistently exceeding inverter-supplied energy. Integration of photovoltaic panels into the grid reduces PLN electricity consumption by up to 30% during optimal sunlight periods, achieving an average system efficiency of 15%. This research offers valuable insights into the potential and challenges of implementing photovoltaic panels in educational settings, emphasizing the importance of climate considerations in system design and optimization. Future studies will focus on techno-economic evaluations of solar power installations and harmonic distortion (THD) analysis for larger-scale implementations.]]>
