Saat proses transmisi energi listrik berlangsung maka akan terjadi losses atau rugi-rugi daya sehingga mengalami drop tegangan. Penggunaan saluran transmisi tegangan ekstra tinggi (SUTET) merupakan salah satu solusi untuk mengatasi masalah tersebut. Namun hal tersebut mengakibatkan timbulnya peristiwa korona. Korona dapat menimbulkan rugi-rugi korona serta gangguan terhadap lingkungan sekitar seperti timbulnya audible noise (suara bising) serta radio interference (interferensi gelombang radio). Untuk itu dalam perencanaan pembangunan jaringan SUTET diperlukan analisa tingkat rugi-rugi korona, audible noise dan radio interference yang akan terjadi pada saat level tegangan dinaikkan dari 150 kV menjadi 275 kV. Besar rugi-rugi korona saat cuaca baik terbesar terjadi pada saluran Nagan Raya-Sigli sebesar 29,8669 kW sedangkan yang terkecil terjadi pada saluran Lhokseumawe-Arun sebesar 3,004 kW. Untuk besar rugi-rugi korona saat cuaca buruk terbesar terjadi pada saluran Nagan Raya-Sigli sebesar 82,9637 kW sedangkan yang terkecil terjadi pada saluran Lhokseumawe-Arun sebesar 8,3443 kW. Besar audible noise yang dihasilkan 45,35 dB dimana termasuk dalam skala tingkat rendah menurut Kriteria Perry. Sedangkan radio interference yang dihasilkan 52,77 dB, namun hasil tersebut hanya berpengaruh pada gelombang AM.

The utilization of wind energy as one of the renewable energy sources in Indonesia is still limited. This is due to Indonesia's large wind potential, but it is at low speeds. One modification of wind turbines to overcome this problem is by using inverse taper and taper blades. Inverse taper blades have a chord distribution that increases from root to tip while taper blades have a chord distribution that decreases from root to tip. This research conducts the design and construction of inverse taper and taper blades on small-scale wind turbines using NACA 6412 airfoil type, then tested in the field and obtained the performance of each blade. The design was carried out using blade element momentum theory to obtain the blade geometry shape and perform performance analysis of each type of blade. Based on the simulation results obtained from QBlade, it shows that the inverse taper blade performance has a maximum Cp of 0.52 while the taper blade has a maximum Cp of 0.41. The power graph from field testing results shows that inverse taper blades provide good power generation at low wind speeds compared to taper blades. The inverse taper blade has a cut-in speed of 1.2 m/s and the best power production occurs at speeds of 1-4 m/s.

The community engagement conducted by the lecturers of the Electrical Engineering undergraduate program at the Faculty of Engineering, Syiah Kuala University, aims to enhance the income of young individuals in Kopelma Darussalam, Banda Aceh. Recognizing the need for employment opportunities among youths from lower to middle-income backgrounds, this initiative focuses on providing hands-on skills through training in planning and installing solar panels in residential homes. Consequently, young individuals can become skilled workers in solar panel installation, creating job opportunities, and improving their economic well-being. This training aims to address the increasing demand for renewable energy solutions and the growing interest in solar power adoption among homeowners. Participants will learn about the principles of solar energy, site assessment, system design, installation techniques, and safety procedures. After completing the training, participants are expected to be able to design and install solar panel systems, thereby contributing to the promotion of sustainable energy practices and reducing carbon footprint in residential communities.

Currently, the Customer Service Unit (ULP) of the Blang Kejeren State Power Company (PLN) uses the system of the Diesel Power Power Centre (PLTD). Sistem ini terdiri dari PLTD yang dimiliki PLN dan PLtD Lewa, serta beberapa PLTMH (Pusat Listrik Tenaga Mikro Hidro). Aim of the study is to assess the technical viability of the 20 kV ULP Blangkejeren system if supplied with the Kutacane GI and parallel with Distributed Generation (DG). This is because there is no distribution network that can connect the Blangkejeren ULP load centre to the Kutacane GI. Using the PSS Sincal Power System Analysis Application, load scenarios for power plants and distribution networks are modeled and simulated. The findings indicate that the 20kV Ulp Blangkjeren system provided by GI Kutacana, PLTMH, PLTM Lawe, and PLTD Rema is the most appropriate scenario. This situation is regarded as optimal, with a network voltage of 21.07 kV on the ULP Blangkejeren Connection Guard Bus.

A common problem that occurs in transformers is failure of the insulating oil. One solution to prevent this disruption is to analyze indications of insulating oil failure. Several previous studies on the analysis of transformer insulating oil failure were based on dissolved gas content tests of transformer oil samples. The research was conducted using several methods in processing dissolved gas test results data, such as the TDCG (Total Dissolved Combustible Gas), Roger's Ratio, and Duval's Triangle methods. In this study, two methods were used for comparison, namely the Breakdown Voltage method and the Fuzzy Logic method. The results obtained show that the condition of the insulating oil using fuzzy logic in the Matlab simulation is in accordance with the condition of the transformer insulating oil based on its breakdown voltage characteristics, namely in a normal state. Meanwhile, gas content that is at a high or very high level has a significant impact on the indication of failure in transformer insulating oil, namely the concentration of TDCG and nitrogen gas content.
