Abstract

Food availability has an important role in the resilience and continuity of community life. The agricultural, especially in particular, potatoes, sweet potatoes, soybeans, vegetables, corn, onions, chilies and beans. Water is the main source. Realizing agricultural results, a lack of air supply will certainly have a negative impact on agricultural results that are not optimal. The dry season that hits will have an impact on air shortages, this will of course cause crop failure, making farmers lose money. Various efforts have been made to minimize these losses, one of which is by providing water pumps in their agricultural areas. Utilizing the pump requires continuous electrical energy as the main source to operate it, this will also have an impact on the costs incurred by farmers. The amount of electrical energy produced at the plant is greatly influenced by the optimal configuration factor for placing wind turbines at the location. The value of the optimal configuration is seen based on the high productivity of the electrical energy produced. This research will optimize the placement of wind turbines using 3D–5D and 5D–9D turbine configurations. Temporary research results show that the most optimal configuration is using the 5D–9D model with an energy production cost of 6,083 rupiah per year, and the daily electrical energy produced is 308.08 kilowatts.

Abstract

Energy audits are a crucial step in energy management, providing an indication of a building's energy efficiency. This study, conducted in the Chemical Engineering Building at Malikussaleh University, aimed to evaluate electrical energy consumption by calculating energy consumption intensity (EKE), and to verify compliance with the 2020 Indonesian National Standards (SNI) for the lighting system. Data were collected through direct observation, interviews, and the analysis of documentation. The study focused on analysing lighting levels and electrical energy consumption, including calculating IKE. The results showed that lighting levels in most rooms did not meet SNI standards, with only the terrace area meeting the criteria. The building's daily energy consumption was found to be 402.8 kWh, with cooling loads accounting for the largest proportion. The IKE values for lighting and cooling on both floors of the building were below the required standard, indicating a lack of energy efficiency. The main factors influencing these results were inadequate lighting design, the use of inappropriate lamp types, and suboptimal maintenance of the lighting system. To improve energy efficiency, it is recommended that lamps are added or replaced with high-efficiency ones and that energy planning is improved based on a more comprehensive energy audit. This research contributes to improving energy efficiency in the education sector.

Abstract

This study analyzes the potential and optimization of a solar–wind hybrid power generation system to support sustainable anchovy drying for small-scale fishermen in Ujong Blang Village, Lhokseumawe, Aceh. Field data on wind speed and air temperature were collected on September 20–21, 2025. The measurements indicate that solar energy has a more dominant contribution with an estimated production of 3.7 kWh/kWp·day, while wind energy provides only around 0.37 kWh/m²·day at an average speed of 2.93–5.29 m/s. To meet the energy demand of a 50 kg/hour fish dryer (3.8 kW), a PV capacity of 4.1 kWp is required for 4 hours of operation or 8.3 kWp for 8 hours. Meanwhile, wind energy requires relatively large turbine swept areas, making it more suitable as a complementary source. The optimal hybrid configuration positions solar PV as the primary source (70–80%), wind turbines as a secondary source (20–30%), and batteries for energy storage. The results demonstrate that a solar–wind hybrid system can enhance the reliability of renewable energy supply efficiently and sustainably to support fish drying operations.
