The need for electrical energy for lighting for the community is an important thing. However, people tend to pay less attention to the savings in the use of electrical energy for lighting in the house, both at night and during the day. When leaving the house empty, in general, the porch light is on all day and night. This is a common thing for the community, but they unconsciously waste the use of electrical energy which will cause an increase in electricity bill bills. To increase knowledge for the community about the importance of saving electrical energy, in this community service counselling will be carried out on saving electrical energy by using automatic, energy-saving lamps. Counselling is done by visiting people's homes to explain the benefits of saving electricity for them. Then distribute and install energy-saving lamps with light sensors. With this service, the community has been able to understand well the benefits of saving electrical energy for them. The use of energy-saving lamps with light sensors can help people to save on the use of electrical energy. With this counselling, the community can save electrical energy for lighting, where the porch light will turn on automatically in the afternoon and will turn off automatically in the morning

The use of a digital stopwatch as a timer for the overcurrent relay is important in order to know the operating time characteristics of the overcurrent relay. This activity aims to design and build a digital stopwatch prototype for laboratory practice activities. The design of the equipment circuit was then made a digital stopwatch prototype and applied to the practical implementation of the MCGG52 type overcurrent relay for laboratory activity in the electrical engineering laboratory at the Faculty of Engineering, Atma Jaya University Makassar. The practical activity to record the operating time of the MCGG52 overcurrent relay using a digital stopwatch was successfully carried out with results that met the working standards of the MCGG52 relay

Pemasangan Panel Surya di Gereja Toraja Jemaat Lembah Kasih Ollon, Buakayu Kabupaten Tana Toraja Simon Patabang; Jeremias Leda

The need for electrical energy for the Toraja Church, Lembah Kasih Ollon Congregation, Buakayu is very important to meet the needs of lighting and sound systems in the church. The location of the church from the city of Makale is approximately 40 km and is located in a valley called the Ollon Valley. The location of the Church has not yet received PLN electricity network services. To meet electricity needs, solar cell-based electrical energy is provided. The function of the solar cell panel is to convert solar energy and then produce direct current electrical energy. Because the lights and sound systems require alternating current, the direct current obtained from the solar panels is converted into alternating current. With the installation of a 160 Wp solar panel, the electricity source at the Toraja Church, Ollon Buakayu Congregation is available, both during the day and at night. Thus, the lighting system and sound system in the church can work properly.

PENGUJIAN SENSITIVITAS DAN AKURASI SENSOR ARUS HALL EFFECT MENGGUNAKAN ARDUINO-UNO Limbran Sampebatu; Simon Patabang; Jeremias Leda

The sensitivity and accuracy of the hall effect current sensor is an important factor in its application considering that electric current is the main parameter in the study of electrical energy engineering, telecommunications and electronics. However, on the other hand, studies related to the sensitivity and accuracy of Hall effect current sensors are still rarely carried out. The method used in this research is an experimental laboratory study using the ACS712 sensor with a variation rating of 5A, 20A and 30A. The results show that the sensitivity is inversely proportional to the ampere rating of the ACS712 sensor where the greater the current rating of the sensor, the lower the sensitivity. While the accuracy is directly proportional to the ampere rating of the ACS712 sensor where the greater the current rating of the sensor, the more accurate the sensor is

The development of business world is entering the era of big data. In meeting supermarkets' sales and purchase targets, the management needs to improve themselves in managing the goods available in the store. The research aims to determine the pattern of purchases that occur in a transaction, find out related and related products in supermarkets, and improve supermarket services to customers. The method applied uses the association rules approach to data mining. Several purchasing data from customers have been able to be analyzed by displaying a diagram as a visualization of the number of specified association rules. The processing results show a relationship above 90%: sugar and coffee with a confidence of 94.4%, shirts and trousers with a confidence of 93.4%, and sugar, milk, and coffee with a confidence of 92.0%. Decisions that can be taken by supermarket management in providing places and goods need to consider and follow product relationships and proximity based on the highest confidence value to provide services to customers effectively and efficiently.

Extension activities were carried out in the Karanganyar Village area, Kec. Mamajang, Makassar. In general, partners have houses that are close to each other or attached to neighbors so that the air circulation in the house is not good and the natural lighting in the house is not optimal. To get optimal lighting during the day, you must use electric lights as a source of lighting. Then to get fresh and comfortable air, partners use air conditioners or fans. With such a situation, partners experience difficulties with the cost of electricity bills which tend to increase every month. The partner's problem is how to reduce the cost of electricity bills which tend to increase every month. To help overcome partner problems, counseling on saving electricity is carried out. The main ingredients of energy-saving counseling are introducing energy-efficient electrical devices, building awareness of the importance of saving energy, and how to calculate the cost of a monthly electricity bill in one household. Based on the results of the implementation and evaluation of energy saving counseling and the results of observations, partners have realized how important it is to save energy. The cost of electricity bills from several partners has decreased compared to the previous period. This counseling has increased partners' knowledge so that they understand more about the positive and negative impacts of regular and disciplined use of electric power in the household
