Abstract

Penilaian keandalan pendistribusian tenaga listrik ke pelanggan diperlukan untuk mengevaluasi kualitas daya serta mengantisipasi masalah yang ditimbulkan. Keandalan merupakan kemampuan suatu sistem untuk dapat memberikan hasil yang lebih baik pada periode waktu dan dalam kondisi operasi tertentu. Pada penelitian ini dilakukan analisis prioritas gangguan dengan menggunakan diagram pareto untuk mengindentifikasi permasalahan yang dominan sehingga dapat mengetahui prioritas dari penyelesaian masalah. Penilaian keandalan sistem distribusi 20 kV pada penyulang BG-2 PT.PLN (Persero) ULP Binjai Kota menggunakan Failure Modes Effect Analysis (FMEA) dengan indikator indeks kenadalan seperti System Average Interruption Duration Index (SAIFI), Costumer Average Interruption Frequency Index (SAIDI), Costumer Interruption Duration Index (CAIDI), Energy Not Supplied (ENS) dan Average Energy not Supplied (AENS). Hasil diperoleh memperlihatkan, gangguan terbesar disebabkan oleh alat pengukur dn pengaman (APP) sebanyak 43 kali dengan presentase gangguan sebesar 48%. Indeks keandalan untuk SAIFI sebesar 8,42 kali/tahun, untuk SAIDI sebesar 25,33 jam/tahun dan CAIDI sebesar 3 jam/gangguan. Nilai SAIFI dan SAIDI belum mencapai standard yang telah ditetapkan oleh PT. PLN (Persero) dan standard IEEE, sementara untuk nilai CAIDI sudah mencapai standard PLN tetapi belum memenuhi standard IEEE. Perhitungan nilai energi yang tidak terjuan (ENS) sebesar 66.541,885 kWh dan AENS sebesar 5,854 kWh/pelanggan. Kerugian PLN diakibatkan gangguan yang terjadi pada penyulang BG-2 pada tahun 2020 diasumsikan sebesar Rp.89.964.629,-

Abstract

Banyak warga yang mengalami kerugian besar akibat kelalaian saat terjadi kebakaran rumah. Oleh karena itu, perlu dikembangkan sistem pendeteksi kebakaran yang dapat dikendalikan dari jarak jauh melalui Internet dengan menggunakan aplikasi Blynk Iot 2.0 yang terpasang di smartphone. Komponen fire detector menggunakan fire detector LM393 untuk mendeteksi api dan komponen smoke detector menggunakan smoke detector MQ7 yang terhubung dengan mikrokontroler Esp8266 dan buzzer. Alat yang dibuat penulis saat ini masih bersifat Prototype, artinya masih berupa purwarupa sebuah ruangan 40 cm x 30 cm yang dilengkapi sensor api, sensor asap serta sensor suhu dan kelembaban. Pengiriman data informasi pada perangkat menggunakan jaringan WIFI , jika perangkat tidak terhubung jaringan WIFI maka data peringatan tidak akan terkirim.

Abstract

In this era of globalization, international collaboration in higher education has become a key factor in improving academic quality, research, and technological development. Universiti Malaysia Perlis (UniMAP), as an institution that focuses on technical and vocational education, utilizes the philosophy encapsulated in its tagline: "Knowledge, Sincerity, Excellence" to strengthen its international position. This article aims to explore how UniMAP utilizes this tagline as a strategy to strengthen international collaboration and improve global performance. Through the implementation of strategies based on knowledge, sincerity, and excellence, UniMAP has not only improved the quality of education and research but also built sustainable international partnerships. Significant achievements are evident in its international rankings, collaborative research networks, and high graduate success rates. Despite challenges such as geographical limitations, cultural differences, and university competition, UniMAP has successfully overcome these obstacles by encouraging cross-cultural communication and building similar partnerships. The results of this study indicate that the values ​​embedded in UniMAP's tagline play a significant role in strengthening the university's international position and driving sustainable improvements in global performance.

Abstract

The international collaboration between the TVET Center of Universiti Malaysia Perlis (UniMAP) and the Faculty of Engineering, Universitas Islam Sumatera Utara (FT-UISU) aims to strengthen ASEAN regional synergy through a Technical and Vocational Education and Training (TVET)-based community service program. This initiative focuses on empowering local communities through technical training relevant to industry needs while fostering stronger connections between academia, industry, and society. Key programs include training in 3D design, digital printing, and workshops on basic automation and the Internet of Things (IoT). The collaboration not only enhances local skills but also broadens the international academic networks of both institutions, contributing to the achievement of Sustainable Development Goals (SDGs). Challenges such as differences in curriculum systems and cross-border logistics were successfully overcome through intensive communication and shared commitment. Moving forward, both institutions aim to expand this collaboration through the development of joint TVET curricula, student and faculty mobility, and community-based research projects.

Abstract

Bencana alam merupakan fenomena yang tidak dapat dihindari dan sering menimbulkan dampak signifikan terhadap kehidupan sosial, ekonomi, serta lingkungan masyarakat. Indonesia sebagai negara kepulauan dengan kondisi geografis yang kompleks, sangat rentan terhadap bencana hidrometeorologi seperti banjir, tanah longsor, dan cuaca ekstrem. Desa Sriwijaya merupakan desa yang terkena dampak banjir besar yang terjadi pada bulan November 2025, yang mengakibatkan sumberr air bersih di desa tersebut sangat minim sekali.Metode pelaksanaan mencakup sosialisasi, pelatihan, penerapan teknologi, pendampingan, evaluasi dan keberlanjutan program terkait kegiatan penyuluhan, pelatihan dan pendampingan tentang pembuatan sumur bor sebagai kebutuhan pokok yang dibutuhkan masyarakat desa pasca banjir. Kegiatan pengabdian kepada masyarakat meningkatkan wawasan dan pengetahuan masyarakat desa mengenai pentingnya air bersih dan pemberian mesin sumur bor untuk memenuhi kebutuhan air bersih bagi masyarakat desa Sriwijaya Kabupaten Aceh Tamiang

Abstract

This article aims to analyze the economic feasibility of CNC machine investment in a medium-sized manufacturing industry using the Net Present Value (NPV) approach. The research method used is a library search, which involves collecting and analyzing secondary data from literature related to CNC machine investment, feasibility studies, and NPV calculation methods. The analysis begins with identifying initial investment costs, projecting annual net cash flows, determining the discount rate, calculating the NPV, and analyzing sensitivity to changes in key variables. The results show a positive NPV, indicating that this investment is financially profitable and feasible. In addition to financial benefits, the use of CNC machines also provides strategic benefits such as increased production efficiency, reduced reject rates, and improved product quality. Therefore, investing in CNC machines is recommended as a strategic step to increase the competitiveness and productivity of medium-sized manufacturing industries amidst increasingly fierce market competition.
