Sistem kontrol dan monitoring energi listrik menjadi hal yang krusial bagi konsumen listrik karena hal ini berkaitan dengan besarnya biaya energi listrik yang harus dibayarkan oleh konsumen. Penggunaan  mikrokontroler dalam sistem kontrol dan monitoring energi listrik adalah untuk mempermudah proses pengontrolan memproses data untuk dikonversikan menjadi daya listrik dan menyimpannya setiap waktu tertentu serta ditampilkan melalui LCD. Sistem kontrol dan monitoring energi listrik berbasis mikrokontroler ini sangat tepat untuk diterapkan pada suatu lokasi yang terdiri dari beberapa konsumen dengan kebutuhan yang berbeda. Sebagai contoh adalah lokasi kost atau penginapan dengan banyak kamar, lokasi usaha dengan beberapa kios dan lain-lain.  Alat ini bekerja dengan mengukur tegangan dan arus yang akan diolah datanya oleh mikrokontroler untuk dijadikan parameter menghitung dan membatasi energi listrik terpakai pada setiap pelanggan. Agar semua konsumen dapat termonitoring secara terpusat maka dibutuhkan personal komputer yang akan berkomunikasi dengan setiap mikrokontroler di masing-masing konsumen melalui komunikasi RS-485. Alat yang mempunyai presentase error pengukuran day asebesar 3.33 % ini akan dapat berkomunikasi maksimal 1,2 km, dan parameter energi listrik seperti tegangan, arus, daya listrik dapat dipantau dan dikendalikan dari jarak jauh melalui computer.   Electricity control and monitoring system becomes crucial for electricity consumers because it is related to the amount of electricity cost that must be paid by consumers. The use of microcontrollers in the control system and monitoring of electrical energy is to facilitate the process of controlling the data processing to be converted into electrical power and store it at any given time and displayed through the LCD. Control system and monitoring of microcontroller-based electrical energy is very appropriate to be applied to a location consisting of several consumers with different needs. For example is the location of boarding or lodging with many rooms, business locations with several kiosks and others. This tool works by measuring the voltage and current that will be processed by the microcontroller data to be used as parameters to calculate and limit the electrical energy used in each customer. In order for all consumers to be monitored centrally then it takes a personal computer that will communicate with each microcontroller in each consumer through RS-485 communications. The tool that has a percentage error of power measurement of 3.33% will be able to communicate a maximum of 1.2 km, and electrical energy parameters such as voltage, current, electrical power can be monitored and controlled remotely via computer

The use of lighting installations installed in the RW VIII Kelurahan Kesatrian has various aspects interms of installation and use. To prevent losses due to the installation, the solution is to conduct electrical installationtraining. As a result of this training, it is hoped that the community can make efforts to install lighting or independentlyin their respective homes safely and correctly. The purpose of this Community Service is to provide knowledge andskills in installing electrical installations correctly and safely, given the use of household electrical appliances withvarious brands, each brand of household electrical equipment has different reliability, and utilization and operationthat require safety for users.

The tendency for the price of using solar PV (photovoltaic) to become cheaper means that the portion of the use of this solar energy source is encouraged to be larger along with the addition of the portion of renewable energy (EBT) generators based on PLN's 2021-2030 Electricity Supply Business Plan (RUPTL). As a step to mitigate this problem, a power electronics circuit application is needed in the form of a boost converter or what can be called a step-up DC-DC converter. In this study, the boost converter design modeling is made a closed loop. There is feedback by adding a PID controller to adjust the duty cycle as a function of switching on or off MOSFET so that the output voltage is as desired (setpoint) and adjusts to needs of load. Open-loop design modeling is also included as a comparison. The design stage begins with determining the circuit design, calculating component specifications, and simulating using MATLAB R2013a software and hardware implementation. From the test results, it was found that the boost converter can increase the solar PV voltage varies (17.34-19.13 Volts). In the closed loop boost converter circuit with a constant load of 129.96 Ω with varying duty-cycle value set by PID controller with value of Kp=0.005 Ki=9.75 Kd=0.00000029, the average output voltage is 36. 0067 Volts and stable at the desired setpoint of 36 Volts.
