Energy needs in Indonesia in particular and the world in general continue to rise due to population growth, economic growth and energy consumption patterns themselves are constantly increasing. One of the fast growing renewable energy in the world today is wind energy. Wind energy is a renewable energy that is very flexible. In general, the utilization of wind power in Indonesia is less attention. Until 2004, the installed capacity of wind power utilization is only up to 0.5 MW from 9:29 GW potential. One method used to measure the wind energy potential of wind energy for electricity generation is by using the Weibull method. From the analysis that has been carried out by the method of Weibull can be concluded that the wind energy potential of wind energy for electricity generation in Banda Aceh does not meet the eligibility criteria.

In meeting the need for healthy food and drinks that have been verified as halal, the government has established BPOM (Food and Drug Supervisory Agency) and LPPOM MUI (Institute for the Assessment of Food, Drugs, Cosmetics, Indonesian Ulama Council) so that food products circulating are continuously monitored and halal maintained. Food and beverage products must be verified and rigorously tested by the two institutions, so that these food and beverage products can be labeled as halal and healthy. However, some foods and drinks that have not been verified as halal and healthy are still circulating among the public. To make it easier for the public and sellers of food and beverage products, they need a system that can see directly the food products that they are going to buy have been verified as halal and healthy. This research designs a system which can be used as input for practical and easy solutions in verifying halal products using NFC (Near-field communication). NFC is one of the smartphone features that has been widely applied lately. The use of this features can directly attach a smartphone at a distance about 0-2 cm to the product to be purchased and has been integrated with an NFC tag and only takes approximately 1-2 seconds to find out the product information from a smartphone that connected to the internet through the BPOM and LPPOM MUI websites.

Hydrokinetic power plants are able to produce energy only by harnessing the kinetic energy of flowing water. Compared to dam-based hydroelectric power plants, hydrokinetic power plants have minimal impact on several issues e.g. environmental, health, social and political conflict. Similar to wind turbines in a wind farms, hydrokinetic turbines in tidal farms also generate a wake effect, which results in less kinetic energy on downstream turbines compared to upstream turbines. This article shows the simulation results of three hydrokinetic power generation systems installed in series on the same water stream such as river or aqueduct. The upstream turbine generates wake effect and resulting a velocity deficit both in the two downstream turbines. Bastankhah Porté-Agel model for wake effect was used in this study. The simulation results show that the downstream turbine cannot maintain the given voltage reference and loses the stability of the power control if the water velocity decreases. Several recommendations regarding series configuration of the hydrokinetic system are also presented in order to support the control stability.

Monitoring the output parameters of a solar module is required for assessing its performance under real operating conditions. This paper presents a new technique for monitoring the output parameters i.e. current and voltage of solar module directly under real operating conditions. In this new monitoring technique, the output parameters of a solar module can be directly processed in real time condition and their results are displayed in a graph. The monitoring system is developed using microprocessor Arduino Atmega 328P and equipped with calibrated current and voltage sensors, a data acquisition system which is integrated directly into an Excel spreadsheet using the PLX-DAQ application program and a memory card for backup. The monitoring system is connected to a computer using a RS232 serial port. The collected data is saved directly into a spreadsheet and plotted in real time. This technique provides an easy access to the collected data for further analysis.

Students need to learn about power distribution networks in order to comprehend how electricity is distributed from its source to its consumers. However, many students lack interest and have trouble understanding the theory of distribution systems. The goal of this study is to develop a tiny teaching tool that will be used in Class XI of the Electrical Network Engineering Department at SMK Negeri 2 Banda Aceh to teach the concept of power distribution networks. The objective is to validate and assess the merits of employing small media while instructing students about power distribution systems. Data are gathered using an experimental methodology in this study and through validation, observation, documentation, and testing. The study's findings suggest that making small media for power distribution systems is appropriate for teaching. When compared to the pre-test score of 61.65, the final test results demonstrate a remarkable improvement, with an average post-test score of 90.00. Therefore, SMK Negeri 2 Banda Aceh's use of teaching materials utilizing tiny power distribution systems is very effective in improving students' learning outcomes in the subject of power distribution systems.

In educational institutions, occupational safety and health are significant issues. Students and institutions may suffer losses as a result of accidents and issues with occupational health. Thus, it's critical that pupils have comprehensive understanding of K3. SMK Negeri 5 Telkom Banda Aceh observations revealed a deficiency in instructional resources for K3 instruction. Therefore, the goal of the research is to use the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) in conjunction with the Research and Development (R&D) technique to design an Occupational Safety and Health Module. Student response questionnaires, validation questionnaires from media experts, and material experts were used in the data collection process. According to the research findings, 92.5% of material experts and 77.5% of media experts believe that the K3 module is adequate from a media standpoint. Student responses also attain a score of 92.4%, suggesting that the K3 module is appropriate for use in education. In summary, the K3 module has emerged as a highly successful educational tool for maximizing students' engagement with K3.
