Abstract

The use of smartphones can significantly impact positive and negative users, especially among teenagers today, and teenagers still get much information via smartphones without adult supervision. This disrupts adolescent health and the growth of socialization abilities because of difficulties communicating with the environment; the child becomes irritable, and his knowledge does not develop. Middle school teenagers experience significant physical, social, and emotional changes, which will develop a stronger self-identity and require social interaction with society by frequently using smartphones in every social and other activity. This activity aims to provide understanding to teenagers to be more competent in using communication technology and change the mental habits of teenagers who depend on smartphones. The event was held at SMP IT Al Jawahir Sunggal, Deli Serdang, with 25 participants. This activity uses lecture, discussion, and test methods. Based on the pre-test and post-test presentation, the test score increased 56% after socialization, 36% was neutral, and 8% decreased after socialization.

Abstract

The electric welding system requires a welding transformer that is usually classified as direct current (DC) or alternating current (AC). In electric welding, a separate transformer is provided as a source for regulating the required current during the welding process. The operation of the transformer during welding is closely related to the needs of the current, the diameter of the welding wire, and the thickness of the material being welded. The difference between a conventional coil winding transformer and a manufacturer's coil winding transformer lies in the welding results and the specimens obtained from testing a type of material, which is steel plate ST37 with a thickness of 8mm and a width of 40mm, using electrodes E-6013 with diameters of 2.6mm and 3.2mm. The welding joint method used is a single V groove butt joint. The welding tests of both transformers prove that the penetration, width, and height of the weld bead with the Manufacturer's coil winding transformer are quite good compared to the Conventional coil winding transformer. Based on the welding test results of both transformers, the Manufacturer's coil winding transformer using electrode type E-6013 achieved the highest bending test strength with a Crack load value of 33.701 kN, while the Conventional coil winding transformer had a value of 27.335 kN, both using the same current of 120 Amperes.".

Abstract

Technological developments are increasingly developing, especially in the world of aviation. Therefore, aviation vocational institutions provide sources of knowledge and technology that can be implemented in several ways, including by carrying out community service activities related to aviation technology. Currently, the aerospace insight possessed by the community is still limited, especially for students of SMA Negeri 1 Tanjung Morawa. This PkM activity aims to provide education to the community as basic capital to increase aerospace insight needed by the job market in the aviation sector. The method used in this activity is counselling by providing material about technology in the world of aviation. The results of this activity show that students of SMA Negeri 1 Tanjung Morawa experienced an increase in knowledge about technology in the world of aviation, as evidenced by the percentage of participant posttests of 85% for increased scores and 0% for decreased scores. From this counselling, it can be concluded that participants can gain new knowledge about aviation technology from the implementation of this activity.

Abstract

Jakarta, as a rapidly growing urban area, faces challenges in balancing energy demand with supply while addressing environmental concerns associated with traditional energy sources. Electrical energy production prediction in urban environments like Jakarta is crucial for effective energy management, ensuring stable supply, and promoting sustainable development. The prediction of electrical energy production in Jakarta is critical for ensuring stable and sustainable energy supply. This research proposed the application of the adaptive neuro-fuzzy inference system (ANFIS) as a predictive tool specifically tailored for Jakarta's energy production prediction context. The research methodology used in this study is the ANFIS. Five levels make up the architecture of the ANFIS model: output, normalization, defuzzification, rule evaluation, and fuzzification. The fuzzification layer converts input variables into linguistic terms using membership functions, while the rule evaluation layer calculates the activation strength of each rule based on the input values. The predicted results of Jakarta electrical energy production from 2023 to 2028 are 65,288 GWh and there is an annual increase of 5.25%. The error contained in ANFIS is with a root mean square error (RMSE) value of 0.0001058% and a mean absolute percentage error (MAPE) value of 0.00875%.

Abstract

Fossil fuel power plants still play an essential role in providing energy worldwide, but their environmental impact will contribute significantly to emissions and environmental pollution. To reduce these emissions, renewable energy offers a solution to reduce global emissions. This study proposes a renewable energy modeling system using hybrid optimization of multiple energy resources (HOMER) simulation on renewable energy systems for economic savings. This simulation can combine photovoltaic (PV), wind power (WP), and converter systems. The hybrid combination of PV and WP is the most appropriate and economical choice at the research location. The results showed that the modeling of the renewable energy hybrid system made a significant contribution, with an initial investment cost of IDR 107,474.43 million and an annual operating cost of IDR 22,540.23 million, 41% lower on condition now with an estimated return on investment of 11 years. The results of this study can be used as recommendations for similar conditions in other places. Policymakers can use this model to provide incentives and have a positive impact on hybrid power plants (HPS) in neutralizing global emissions.

Abstract

Waste management poses a significant environmental challenge in Indonesia. Ineffective waste handling can lead to various negative environmental impacts. Meanwhile, energy demand continues to rise in line with population growth. One innovative solution to address these issues is the use of Thermoelectric Generator (TEG) technology in a Waste-to-Energy Power Plant (PLTSa) system. This study aims to design and develop a power generation system that utilizes heat energy from the combustion of waste—specifically plastic and paper—to generate electricity, which is then used as a power source for lighting systems. This research uses a quantitative descriptive method to explain a phenomenon or process without relating it to other variables. The energy conversion process is carried out using six TEG modules connected in series to maximize voltage output. The generated voltage is then regulated and stored in a battery using a Solar Charge Controller (SCC), and monitored through an INA219 sensor and an Arduino UNO microcontroller. The system is also equipped with a photocell sensor that enables the light to operate automatically based on the ambient light intensity. Test results show that a temperature difference (∆T) of 227.7°C between the hot and cold sides of the TEG can produce a maximum voltage of 15.87 Volts. The monitoring and automatic control system functions effectively in tracking the TEG output and switching the light on or off according to environmental lighting conditions. Therefore, this system presents a viable alternative solution for renewable energy generation based on waste management.

Abstract

Pengelolaan beban listrik secara manual pada fasilitas besar seperti auditorium sering kali menghadirkan tantangan dalam hal pengawasan, keselamatan, dan keandalan sistem. Penelitian ini bertujuan untuk merancang sebuah sistem monitoring dan kendali beban listrik berbasis Home Assistant yang terintegrasi pada Auditorium Politeknik Penerbangan Medan dengan metode penelitian penelitian dan pengembangan (research and development). Platform Home Assistant digunakan sebagai antarmuka utama yang memungkinkan pengguna untuk mengakses monitoring status beban listrik secara real-time, menghidupkan atau mematikan peralatan secara otomatis maupun manual pada sistem. Penelitian ini telah membuktikan bahwa sistem mikrokontroler bisa terintegrasi ke peralatan keras listrik, selain itu sistem ini juga memonitoring daya, tegangan, arus dan frekuensi pada instalasi sistem. Hasil implementasi menunjukkan bahwa sistem mampu memberikan visibilitas penuh terhadap kondisi kelistrikan dan memberikan hasil monitoring secara real-time.
