Abstract

Abstrak: Kepolisian Air Timor Leste memiliki armada kapal patroli yang bertugas mengawasi dan mengamankan perairan Timor Leste dari berbagai potensi kejahatan di laut. Selama ini kapal-kapal patroli didatangkan dari Indonesia, karena keterbatasan galangan kapal lokal, termasuk untuk kapal-kapal berbahan Fiberglass Reinforcement Plastic (FRP). Berangkat dari hal tersebut, Politeknik Perkapalan Negeri Surabaya (PPNS) mengadakan program Pengabdian kepada Masyarakat (PkM) Internasional dalam bentuk pelatihan pembuatan kapal FRP untuk anggota Kepolisian Air Timor Leste. Tujuan dari program PkM Internasional ini adalah memberikan ketrampilan teknis kepada anggota Kepolisian Air Timor Leste dalam pembuatan dan perawatan kapal-kapal berbahan FRP. Bentuk pelatihannya adalah praktik langsung pembuatan kapal FRP dengan metode Stitch and Glue, dengan ukuran kapal yaitu panjang 2 meter, lebar 1 meter dan tinggi 0,4 meter. Pelatihan diikuti oleh 6 (enam) orang anggota Polisi Air Timor Leste selama 5 hari di Kampus PPNS. Evaluasi terhadap pemenuhan tujuan pelatihan dilakukan dengan observasi terhadap capaian ketrampilan peserta dalam pembuatan kapal berbahan FRP. Luaran dari PkM ini adalah 1 Unit kapal FRP dan ketrampilan teknis pembangunan kapal FRP oleh peserta dari anggota Polisi Air Timor Leste.Abstract: The Timor Leste Coast Guard has patrol boats for monitoring and securing the waters of Timor Leste. Most of the boats have been imported from Indonesia, due to the limited availability of local boatyards. Based on these circumstances, the Surabaya Shipbuilding State Polytechnic (PPNS) held an International Community Service program for the Timor Leste Coast Guard officers. The purpose of this program is to develop competency in the boatbuilding and maintenance of FRP boats. The training was conducted in the form of boatbuilding practices in making FRP boats using the Stitch and Glue method, with the boat dimension of 2 meters length, 1 meter wide and 0.4 meters height. The training was attended by 6 (six) officers of the Timor Leste Coast Guard for 5 days at the PPNS Campus. Evaluation of the fulfillment of training objectives is carried out by observing the achievement of participant skills in making FRP ships. The output of this program was 1 unit of FRP boat and technical skills in FRP boatbuilding of the Timor Leste Coast Guards Officers.

Abstract

The reliability of web-based conference systems is crucial for ensuring smooth services during periods of high activity. This research evaluates the performance of the ICOMTA PPNS journal website by conducting load testing using Apache JMeter with scenarios ranging from 50 to 5000 virtual users, each executed for one hour. The evaluation focuses on response time, error rate, throughput, and bandwidth usage. The results indicate that the website performs reliably with up to 200 concurrent users, demonstrating stable response times and no recorded errors. However, once the load surpasses 300 users, response times increase sharply exceeding 60 seconds and errors begin to appear, suggesting that the server has reached its performance limit. Under the heaviest load of 5000 users, throughput continues to rise, but overall service quality declines significantly. These findings highlight the need for server enhancements or migration to cloud-based infrastructure to ensure stable performance during peak usage.

Abstract

The increasing use of electric forklifts in industrial environments requires charging power supply systems that are technically reliable and compliant with updated electrical safety regulations. However, empirical studies evaluating the regulatory compliance and safety risks of electric forklift charging panels—particularly under Indonesia’s Minister of Energy and Mineral Resources Regulation No. 1 of 2023—remain limited, indicating a clear research gap. This study aims to assess the compliance level of an existing electric forklift charging power supply panel and to propose a redesigned panel that meets regulatory and safety requirements. An observational assessment was conducted using a structured compliance checklist derived from ESDM Regulation No. 1 of 2023, covering protection systems, grounding, monitoring instruments, labeling, and operational safeguards. Quantitative compliance scoring and risk-based evaluation were applied to identify technical deficiencies and associated electrical hazards. The results show that the existing panel complies with only 58% of mandatory requirements and presents several high-risk conditions, particularly due to inadequate protection devices, lack of electrical monitoring, and insufficient grounding. A redesigned single-line diagram was subsequently developed and evaluated, achieving 100% compliance with mandatory and recommended criteria. The proposed design significantly reduces electrical safety risks, improves system reliability, and ensures full regulatory compliance, providing a practical reference for the development of safe and reliable industrial electric vehicle charging infrastructure.
