Home Automation is one of the advances in technology and communication by automating the control of electrical devices at home. With this method, home electronic devices can be controlled using a remote control system without having to touch the home appliances themselves. Along with the development of the operating system on mobile devices gives birth to innovation and creativity that is in line with the needs of its users, from mere communication tools to information centers. One of the innovations in the field of daily life of its users is Home Automation which allows control of electrical devices so that it can save electricity consumption at home that can be done remotely both in the same location or in other rooms with sensors and user interface design from Android to simplify monitoring. The Home Automation application communicates via MAC addresses on Android registered in Wemos D1, which Android can be used to control automatically, in this study using the Wemos D1 module as a brain or control center that will receive data from Android for later processing to the lamp output , motion sensor (PIR), DHT22 sensor, fan, and door lock by using a solenoid that can be controlled automatically from any sensors connected to the Wemos D1 microcontroller.

The two-axis Sun tracker with the tetrahedron geometry that has been developed has an error percentage of 31.26% and a speed of 0.063 m/s. The value of the accuracy and speed is still considered low for tracking sunlight in open space conditions. The research aims to improve the accuracy and speed of the tetrahedron tracker sun. The method used to obtain tracking accuracy is to implement a control system that forms a tracking system using the proportional integral derivative (PID) control and modifies the sun's light by adding a sun tracker and laser to the top of the tetrahedron structure. In addition, the motor used to measure the state of the horizontal and vertical axes is the DC Stepper type. The results obtained indicate the level of accuracy of the modified sun tracker system is 0.650 on the X-axis and 0.540 on the Y-axis with a speed of 0.091 m / s. From these results, it can be concluded that the sun tracker modification is able to track sunlight properly with an average tracking error rate of 0.78% on the X-axis and 4.67% on the Y axis.

With the undeveloped BAPV(Building Applied Photovoltaics) at Office Building and Public Facilities, Caused the high price of solar modules and the lack the economic study on the use of solar modules that housed in the Banda Aceh region. Furthermore, the price of solar modules is expensive, so people think it will cost so much funds to building a BAPV’s system. These problems could be overcomed if the existing technical studies and economic studies of the application of the BAPV’s system. This study aims to assess the application of the BAPV’s system on institutions building in terms of technical and economic value, in this case the building that is used as the study object is the Polytechnic Aceh’s Building. The method that used in the technical studies are theoretical calculations and simulations using helioscope software, while the methods used for economic studies is using the methods of cost-benefit analysis (cost benefit analysis). The method used to find the NPV (Net Present Value), PP (Payback Period), IRR (Internal Rate of Return), and BCR (Benefit Cost Ratio). If the average value of solar radiation reaching 4.79 kWh / m2 / day and the average daily energy requirement is 592 kWh, the energy generated from BAPV-PLN hybrid system on the roof of the object building will reach the amount of 237 MWh/year with the capacity charge controller used is 7490 A and the capacity of the battery used is 64.487 Ah. Panel tilt angle used is 25o and the type of panel used is Monocrystalline manifold. From the economic value will obtained NPV value of Rp. 20.022.106.937, PP during 5,2 years, IRR of 36% and 3,49 of BCR. Based on the evaluation results of the feasibility study, the project of hybrid BAPV-PLN’s system on the roof of the Polytechnic Aceh’s building can be realized, because its already meet the criteria of the feasibility study to make the systems get established in real term.

Analisis potensi energi terbarukan banyak menggunakan dataset dari sumber sekunder seperti Solargis, ECMWF, NASA, dan Meteonorm karena dapat memberikan informasi yang relevan dan konsisten dalam jangka panjang sampai puluhan tahun. Penelitian ini membandingkan potensi energi matahari dan angin menggunakan reanalysis dataset ECMWF dan NASA POWER di Pulau Teupah dalam skala jam dari tahun 2012 sampai 2021. Metode analisis yang digunakan adalah kuantitatif dan deskriptif. Hasilnya, potensi energi matahari dan angin untuk dataset ECMWF lebih besar dibandingkan dataset NASA POWER. Namun secara karakteristik potensi energi matahari dan angin baik perhari dan perbulan untuk dataset ECMWF dan dataset NASA POWER tidak berbeda secara signifikan. Potensi energi matahari di Pulau Teupah lebih direkomendasikan untuk dikembangkan sebagai pembangkit energi terbarukan daripada potensi energi angin pada ketinggian kurang dari 50 Meter.

This research focuses on analyzing power losses due to load imbalance in the medium-voltage distribution network in Pasar Aceh. The aim is to determine the magnitude of power losses that occur at the distribution substation in Pasar Aceh. The research method involves analysis, calculations, and simulations using the ETAP 12.6 software. The results of the analysis indicate that load imbalance in the Pasar Aceh substation leads to power losses. The Trafo Samping Pasar Aceh experiences power losses of 0.77% with a load imbalance of 16.33%. The second transformer in the BNI 46 area incurs power losses of 0.98% with a load imbalance of 30.33%, and the transformer in the BLKG KOTTY area has power losses of 1.17% with a load imbalance of 50.33%. These findings affirm that the greater the load imbalance, the higher the resulting power losses in the electrical distribution network.

Early childhood education (PAUD) is very important to prepare an educated generation for the nation and state, and the role of early childhood educators (PAUD) is very important in the development of students. Educators need to go beyond traditional learning by providing learning innovations that utilize information technology, including the ability to master the latest information technology. The focus of the Community Service Program (PKM) is to improve the quality of human resources (HR) of PAUD organizers in Syiah Kuala District, Banda Aceh Province in the field of information technology, so that they are able to support the management of learning and educational activities. In improving the quality of kindergarten teaching staff in the field of information technology is related to supervision management and making daily learning implementation plans (RPPH). With a system that allows teachers to quickly resolve administrative problems, it is hoped that they can use their time to further develop their knowledge and skills regarding PAUD administrative problems.
