Abstract

Air ballast yang berfungsi sebagai pemberat dan penyeimbang (stability) kapal yang di bawa oleh kapal dari suatu pelabuhan muat (loading) ke pelabuhan bongkar (discharge), di dalam air ballast berpotensi tedapat mikroorganisme, bakteri yang dapat menyebabkan pencemaran ekosistem laut di pelabuhan sekitar. Oleh karena itu IMO (International Maritime Organization) memberlakukan satuan standar D-1 (Ballast Exchange) dan D-2 (Ballast Treatment). Kapal VLGC Pertamina Gas 2 sudah menerapkan aturan tersebut dengan memasang Ballast Water Treatment System (BWTS) guna mencegah terjadinya pencemaran laut akibat air ballast yang di buang oleh kapal. Mengingat peran penting dalam BWTS, perawatan yang harus dilakukan sesuai jam kerja (running hours) yang ada pada manual book guna mencegah kerusakan. Penerapan hours meter berperan penting dalam monitoring jam kerja sebagai dasar perawatan peralatan BWTS. Penelitian ini menggunakan mikrokontroller Wemos D1 R1 sebagai pusat pengolahan data. Sistem ini memanfaatkan modul RTC DS3231 sebagai penghitung durasi waktu hours meter serta menggunakan output LCD 20x4 dan teknologi Internet of Things. Tujuan dari penelitian ini adalah merancang dan membangun sistem yang memberikan kemudahan bagi petugas dalam memantau dan menganalisis durasi waktu hours meter pada mesin Ballast Water Treatment System melalui website. Dengan adanya monitoring hours meter ini dapat mengukur dan mencatat total waktu operasional suatu mesin. Sehingga pemilik atau petugas dapat merencanakan pemeliharaan dan perawatan secara lebih efektif, meminimalisir terjadinya kerusakan dan memastikan mesin tetap bekerja secara optimal.

Abstract

Digital transformation in parking systems is essential to improving operational efficiency, staff integrity, and customer satisfaction. PT Reska Multi Usaha (KAI Services) has implemented various technology-based parking systems such as Manless, Full Manless, Combo, and LPR. However, several locations still rely on manual supervision, which increases the risk of fraud and inaccurate overnight vehicle data. This study developed an Internet of Things (IoT)-based prototype system to monitor gate status and manage customer surveys automatically, with real-time data transmission to a centralized dashboard. The system utilizes gate position sensors, microcontrollers, and digital survey forms integrated with an online server. Test results show that the system operates effectively without manual input, with an average data latency of 1.57 seconds and sensor detection accuracy of up to 50 cm. The system has the potential to be integrated with the Early Warning System (EWS) Command Center to support safer and more responsive parking services.

Abstract

Electrical energy is a primary need for all levels of society today. In the city of Surabaya, the level of electrical energy demand is increasing. The government, through the State Electricity Company (PLN), continues to strive to meet this need and provide the best service in distributing electrical energy so that it reaches consumers properly and safely. In the community, there is still misuse of electrical energy that can cause fires, wasted electrical power due to technical errors, and the use of substandard electrical materials. This is the basis for providing insight and knowledge to the public about the BENAR electrical installation techniques (Baik, Efektif, Nyaman, Aman, and Rapi) to the community. This community service program was carried out for four days (September 27-30, 2025) starting from a pre-test, presentation of material on the introduction and use of electrical energy, and socialization of the BENAR Electricity Application. Participants also practiced electrical installations using the provided practice modules. From the post-test results, it appears that the level of public understanding and awareness of electrical energy use has increased significantly. With a community of electricity users who have insight and knowledge about electrical energy, disasters caused by the misuse of electrical energy can be reduced and prevented.
