Abstract

In today's digital era, efficient and modern library management has become an essential need for educational institutions. Medan Aviation Polytechnic as one of the institutions under the Ministry of Transportation, requires a library system that can optimize the borrowing and returning processes, as well as enhance services to users. This study aims to design and implement a smart library system based on smart card technology using Near Field Communication (NFC). The developed system utilizes smart cards as library membership cards integrated with NFC technology to facilitate access to the library system. The research methodology includes literature review, system design, implementation, and system testing. The test results show that all smart cards were successfully detected by the system, and only registered cards were allowed access. The maximum reading distance of the NFC reader was 4 cm, with an average access time of 0.42 seconds. The system also accurately classified book borrowing based on study programs. All system features functioned properly and received a high level of user satisfaction, with an average score of 4.59 out of 5, indicating that the system meets user needs, improves service quality, and modernizes library management.

Abstract

This study aims to evaluate how well lightning arresters protect the radio transmitter system in the RRI Medan Building from voltage surge disturbances caused by lightning strikes. Measurement of grounding resistance, field observation, and interviews with relevant technicians are all procedures used. The results of the study indicate that a grounding system with a resistance of less than 5 ohms can reduce voltage surges to a protection level of 99%. Choosing the distance of the arrester installation and conducting periodic maintenance are two important components in maintaining a reliable lightning protection system. It is expected to improve the safety of the device and the continuity of radio broadcasting services in extreme weather situations.

Abstract

Public Street Lighting (PJU) based on Solar Power Plants (PLTS) is one of the renewable energy solutions that is starting to be widely applied in Indonesia, especially in areas that have not been reached by conventional electricity networks. This study aims to examine the environmental and social impact of the implementation of PJU PLTS in two regions with different characteristics. The method used is qualitative descriptive with the support of quantitative data, through interviews, observations, and questionnaire dissemination. The results of the study show that PJU PLTS is able to reduce carbon emissions, improve the visual quality of the night environment, and create a safe and productive space for the community. Social impacts include increasing a sense of security, growing night-time economic activities, and strengthening the social cohesion of citizens. However, challenges such as lack of technical education and community participation are still to be found. This study recommends increasing citizen involvement, battery waste management, and strengthening project sustainability monitoring. These findings reinforce the importance of a sustainable and inclusive approach in renewable energy projects at the local level.

Abstract

Penelitian ini bertujuan untuk menganalisis minat siswa kelas 1 SMA Swasta Al Maksum yang terletak di Desa Cinta Rakyat dalam mengikuti kegiatan ekstrakurikuler futsal, dengan pendekatan Unified Theory of Acceptance and Use of Technology (UTAUT). UTAUT merupakan sebuah model teoritis yang dikembangkan untuk menjelaskan niat dan perilaku pengguna dalam menerima serta menggunakan teknologi. Dalam konteks penelitian ini, model UTAUT digunakan untuk melihat bagaimana faktor-faktor seperti performance expectancy (harapan terhadap kinerja), effort expectancy (kemudahan penggunaan), social influence (pengaruh sosial), dan facilitating conditions (kondisi pendukung) berkontribusi terhadap minat siswa dalam mengikuti ekstrakurikuler futsal. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Data dikumpulkan melalui penyebaran kuesioner kepada 64 siswa kelas 1, terdiri dari 32 siswa laki-laki dan 32 siswa perempuan. Analisis data dilakukan dengan regresi linier berganda untuk menguji sejauh mana pengaruh masing-masing variabel dalam model UTAUT terhadap minat siswa. Hasil penelitian menunjukkan bahwa performance expectancy dan social influence memiliki pengaruh yang signifikan dan positif terhadap minat siswa dalam mengikuti ekstrakurikuler futsal. Sebaliknya, effort expectancy dan facilitating conditions menunjukkan pengaruh yang tidak terlalu dominan. Temuan ini menunjukkan bahwa persepsi terhadap manfaat kegiatan futsal dan dorongan dari lingkungan sosial, seperti teman sebaya dan guru, menjadi faktor utama dalam meningkatkan minat siswa. Penelitian ini memberikan kontribusi bagi pihak sekolah dalam menyusun strategi pengembangan ekstrakurikuler yang lebih efektif, menarik, dan sesuai dengan kebutuhan siswa, khususnya dalam mendorong partisipasi aktif pada kegiatan futsal.

Abstract

PLN UP3 Binjai faces challenges in understanding customer characteristics in each rayon so the service strategy is not fully effective. This study aims to group electricity user areas based on customer type and installed power so that PLN can develop a more targeted and efficient service strategy. The method used in this study is clustering with the K-Means algorithm, with customer data for 2024 from 9 rayons analyzed using the MATLAB R2014b application. Grouping is done with 3, 4 and 5 clusters. The results of grouping 3 clusters produce a variance value of 1.0890, in grouping 4 clusters it produces a variance value of 0.8047 and in grouping 5 clusters it produces a variance value of 0.6093. The results of the Grouping that has been carried out show that 5 clusters provide the most optimal results with the smallest variance value of 0.6093 which shows that the distribution of data between clusters is more homogeneous and representative. Each cluster shows a different combination pattern of rayon, installed power and customer type, which can be used as a basis for developing a more effective service strategy. Keywords: Electricity Customers, Electricity Power, K-Means Clustering.

Abstract

Sukaraya Village, Pancur Batu District, has great potential in the fisheries cultivation sector. Activities such as aeration and water pumping require reliable and efficient energy sources. Solar Power Plants (PLTS) are a sustainable solution that can overcome these obstacles, considering the abundant availability of sunlight in this area. This study aims to design an optimal PLTS system to support fish farming operations in Sukaraya Village. The design is carried out by considering the power needs of the fisheries system, the potential of solar energy, and the efficiency and reliability of the PLTS components. Based on the research results, the PLTS components consist of 15 pcs of 100 Wp polycrystalline solar panels, a 100 A solar charge controller, 4 12V 150Ah batteries, and an inverter capacity of 7000A. The results of calculations in the PLTS planning can distribute electricity with a load capacity of 5,760Wh. The results of the calculation of the overall cost required in the planning of a solar power plant for fish farming are Rp. 51,912,967

Abstract

The problem of limited energy and high household electricity consumption in Indonesia encourages the importance of implementing energy-efficient lighting technology. The still high use of energy-wasting incandescent lamps indicates the low energy literacy of the community in choosing efficient types of lamps. This study aims to analyze and compare the energy efficiency of three generations of lamp technology, namely incandescent lamps, compact fluorescent lamps (CFLs), and LED lamps, with an experimental approach. Testing was carried out using a wattmeter, lux meter, and infrared thermometer in a closed room with controlled conditions. Each type of lamp was tested with a light output equivalent to ±800 lumens. The test results showed that LED lamps had the lowest power consumption of 10 watts with the highest efficiency of 80 lumens per watt and a surface temperature of 45°C. CFLs have a power consumption of 15 watts with an efficiency of 53.3 lumens per watt and a temperature of 70°C. Meanwhile, incandescent lamps consume 60 watts with an efficiency of only 13.3 lumens per watt and a surface temperature of 120°C. Simulation of household use shows that the use of LEDs can save electricity costs of up to 112,500 rupiah per month compared to incandescent lamps. The results of this study provide empirical evidence that LEDs are the most efficient lighting solution in terms of energy, cost, and safety of use for the household sector.
