Abstract

Utilization of solar energy in the generation of electrical energy has been widely carried out using solar panels. One example of its use at Tadulako University is public street lighting using solar energy as a source of electricity. The solar panels that have been installed so far have not been effective because of the different tilt angle positions. There are those who can capture the maximum rays of the sun and there are those who cannot capture the maximum rays of the sun and consequently the electrical energy generated is not optimal.The purpose of this study was to determine the effect of changes in orientation and angle of inclination of solar panels on the output power and to optimize the performance of PLTS-based public street lighting in Tadulako University. The method used to determine the effect of the photovoltaic slope on the output power is to measure the short-circuit voltage and current from various forward directions and tilt angles.The influence of the slope and the direction of the front of the photovoltaic installation can be seen that the highest output voltage is 18.82V in the forward-to-west position with an angle of 5˚. The highest short-circuit current is 3.82A in the front-to-west position with a slope angle of 5˚. The highest output power is 47.97W in the front-to-west position with a slope angle of 5˚.

Abstract

Red chili is one type of vegetable that is quite important in Indonesia, both as a commodity consumed domestically and as an export commodity. Red chili production in Indonesia is still relatively low. The choice of chili plants in this research is based on the high market demand for chili commodities, however, to meet the demand which continues to increase every year, it is necessary to increase chili production through intensification or extensification. Weather factors have a big influence on the development of chili plants. During the long dry season, chili plants cannot grow well, this is due to the lack of water available for the plant's needs, which increases pest attacks. Another factor is excess soil moisture which can trigger chili plants to rot and die. To make it easier to cultivate chili plants, innovation needs to be carried out to help chili cultivators manage their chili plant cultivation, therefore by using the Plantation Irrigation System Automation tool using the Drip Method with Photovoltaic as an Energy Source it is hoped that this can be an innovation in managing the cultivation of chili plants, especially in controlling soil moisture in chili plants.

Abstract

Hydropower plants (PLTA), micro-hydro plants (PLTMH), and pico-hydro plants (PLTPH) in Indonesia use generators with excitation systems to generate fields or magnetic field amplifiers. The use of excitation systems in generators has several drawbacks. In the era of technological development, various types of generators have been developed, one of which is the permanent magnet generator. The Permanent Magnet Synchronous Generator (PMSG) has separate excitation from the synchronous generator and is carried out by permanent magnets to generate the magnetic field instead of coils. This research aims to explore the potential of irrigation channels being utilized as PLTPH using permanent magnet generators. The research method used is the experimental method. The experimental research method is a true experimental method where the equipment is tested and examined. Experimentation involves observation under artificial conditions, where these conditions are created and controlled by the researcher. This study shows that the irrigation channel in Porame Village has the potential to be used as a Pico-Hydro Power Plant (PLTPH) to provide electrical energy as an alternative lighting source, especially at night and during power outages from the national electricity grid (PLN). From the measurement and calculation results, the water flow rate at night is 0.3835 m³/s, with the water power being Pair = 1,901 watts. The type of turbine used is a crossflow turbine, utilizing a permanent magnet synchronous generator.

Abstract

Currently, the energy we use is still using fossil energy. In the future, the need for energy will increase because every year there is a large population growth. If you still use fossil energy and don’t find new energy alternatives, then Indonesia will experience a severe energy crisis and certain places will experience blackouts. One of the efforts so that the wind energy crisis can be minimized is to utilize natural energy that has the potensial to generate energy such as the Wind Power Plant. In this study, planning and simulation of Wind Power Plant were carried out to help reduce the use of fossil energy and help the needs of the community in the Talise Beach area. From the results of the study that the average output of wind turbine production is 1,180/hour winh a maximum production of wind turbines per day of 5,665 kW and the construction system cost (NPC) of Rp. 91,340,660,000. Electrical energy that can be generated from wind turbines by utilizing an area of about 42,021.67 m2 is 10,332,498 kWh/year with a total unfulfilled power of 1,416 kW/year. Lack of power or unmet load can be overcome by the existence of a grid/network.

Abstract

Indonesia is a country that has two seasons, namely the summer and the rainy season, when the rainy season arrives, the rainfall will be very high which can cause flooding. This can be overcome by technological innovation in the form of tools that can work in real-time to detect the condition of water flow in rivers so that losses due to flooding can be minimized. This tool uses a level sensor with the float magnetic level gauge method which is connected to the ESP32 microcontroller module as a sensor data controller and sends the sensor measurement data values ​​to the IoT platform. The sensor measurement results correspond to the water level in centimeters and are sent to the IoT platforms, namely Blynk and Telegram in real-time. The results of sending data to the Blynk and Telegram applications have an average error value of 1.5%.

Abstract

Thermal Overload Relay (TOR) is a tool that works based on heat (temperature) where the flowing current will be converted into heat to affect the bimetal. The length of trip time on the Thermal Overload Relay (TOR) varies depending on the setting value and the magnitude of the load current flowing. This prompted researchers to conduct trials and analyze Thermal Overload Relay (TOR). The research to be carried out here is to conduct a Thermal Overload Relay (TOR) test by adjusting the setting value and giving it more load, then analyzing whether the setting value works according to the setting value. When the motor is loaded, by holding the motor shaft, nothing happens or does not work on thermal overload, because the setting on the thermal overload relay is 2.5 A while the current obtained when the motor shaft is held is 0.40 A
