Indonesia is a country that has an area of sea three times larger than the land area. In line with the rapid development, the need for electricity is also increasing. So that Indonesia has great potential to produce alternative and environmentally friendly energy, namely Sea Wave Energy. Its continuous nature is available all the time. Many potential coastal areas in Indonesia, however, have not been utilized optimally. The purpose of this study is to see the potential of Wave Energy for electricity. For this reason, research was carried out at a location in the Central Sulawesi area, precisely in Salubomba, Central Banawa District, Donggala Regency. In this study a potential study was conducted on 3 types of PLTGL, namely Buoy, OWC, and Pasut Dam, where one will be chosen that meets the wave criteria requirements on the Beach. From the results of research, PLTGL that fulfills the requirements is the type of buoy. Data collection begins with secondary data, namely wind data from Mutiara Station. Then proceed with calculating wave forecasting using the SMB (Sverdrup Munk-Bretschneider) method. The results of this study, Salubomba beach has the potential to be built by the Buoy Type Wave Power Plant, a significant wave height of 0.52 - 3.37 meters with a ruptured depth of 3.95 meters.

In office buildings, electrical energy is needed to meet the needs of lighting to electronic equipment used in the building. To support all of that, a reliable electrical installation system is needed so that all office activities can run well without causing significant problems. Therefore the planning of the electrical installation system in a building must refer to the applicable rules and regulations in accordance with PUIL and SNI. The design carried out refers to PUIL 2011, SNI 03-6575-2001 (Lighting System Design Procedures). The entire electrical installation system gets a 3 Phase supply from PLN. The total power in this building is 80000 watts, so the power needed from PLN to connect is 160 KVA. Conductors used in this installation, use cables with NYM and NYY types with varying sizes in accordance with the calculation of the conveying CRC that has been done.

The PDAM is still using an analog flow meter. For PDAM customers, information on analog flow meters is difficult to access and convert into payment amounts. With an analog reading system, the PDAM officer still records using the manual method of the customer's total water consumption data. From the problems above, we need a digital reading system that can display customer water consumption and payment data that can be accessed by customers. The reading of the volume of water consumed by PDAM customers via SMS is a device designed based on the Arduino Uno microcontroller, equipped with the ability to monitor water usage in real time using SMS media. The reading of the volume of water consumed by PDAM customers uses a water flow sensor that functions to read the flow of water that passes and provides pulse output. Arduino Uno receives pulse output from the water flow sensor which is then converted into a number that shows the number and tariff of water usage of PDAM customers. The LCD displays information on total usage, usage rates, time and date in real time. The SIM800L module sends SMS based on orders received from customers and PDAM officials. The results achieved in this study are the water flow sensor is able to read the amount of water consumption of PDAM customers with an average deviation of 0.034%. Tests show the results of payment conversions are in accordance with the PDAM payment model in Palu City.

Abstract-Overhead line high voltage (SUTT) or commonly called a transmission network or transmission line has very important role in the process of distribution of electrical from power plants to load centers continuously. However, overhead line is one component in the system which is often fault. To avoid damages and greater losses, it has used the distance which is as the primary protection in securing the transmission network or transmission line. In this research, it discussed about one phase-neutral short circuit that happens on line transmission connected to Sidera-Tipo substation by calculating the current fault andoperating time of distance relay using the software of ETAP (electric transientandanalysis program) 12.6.0.

Body flexibility is one of the factors that greatly helps physical health because it can help in prevention, help restore muscle, and improve efficiency in various physical activities. One method to measure the body speed level is Sit and Reach Test using the Sit and Reach Box Scale measurement tool. Technically, this measuring instrument is still manual, simple and its production is still very limited. Therefore we need a measuring device to use electronic components to help process better and better in terms of which can be adjusted to good or bad by using the parameter norm Sit and Reach Test. The purpose of this study is to design a flexibility measuring instrument using a microcontroller based proximity sensor. This tool works with the arduino unu microcontroller as the main controller, HC-SR04 ultrasonic sensor as a distance reader for body flexibility, LED indicators and speakers as a sign of body flexibility, then LCD and delphi 7 applications using serial communication as a display of body flexibility.

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˚.

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.

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%.
