Abstract

The KM. Pusri Indonesia is a bulk carrier owned by PT. Pupuk Indonesia Logistik, specifically designed to distribute fertilizer from producers to various locations throughout Indonesia. Based on the survey results, this study aims to identify factors causing performance decline and implement optimization measures for the compressor. Air compressors play a vital role in providing pressurized air to various ship machinery systems, so decreased performance can hamper operations. The results of this study indicate that the air cylinder filling time increased from the standard specification of 2.4 to 5 minutes to 7.4 to 10 minutes. The main contributing factors are piston ring wear, scale buildup on the low and high pressure valves, and leaks in the cooling pipes. To address this issue, optimization steps that can be taken include replacing worn piston rings, cleaning scale on the valves, and welding leaking cooling pipes. After corrective action, the filling time returned to the normal range of 2.8 to 4.9 minutes. This study emphasizes the importance of compressor maintenance in accordance with the manual and recording maintenance results for evaluation purposes.

Abstract

Efisiensi operasional pelabuhan sangat bergantung pada proses bongkar muat barang yang cepat, akurat, dan terintegrasi. Proses manual yang masih digunakan berpotensi menimbulkan kesalahan pencatatan, keterlambatan, dan sulitnya monitoring real-time. Penelitian ini merancang Sistem Informasi Monitoring Bongkar Muat Berbasis Internet of Things (IoT), dengan memanfaatkan sensor berat, sensor posisi, dan perangkat RFID untuk tracking barang secara otomatis. Sistem menggunakan arsitektur client-server, mengirim data melalui gateway IoT ke server yang terhubung dengan database terpusat. Dashboard berbasis web menampilkan status barang secara real-time. Perancangan sistem dilengkapi dengan ERD, Use Case Diagram, Activity Diagram, dan Sequence Diagram, sehingga mendukung pengembangan dan implementasi sistem. Hasil simulasi menunjukkan sistem mampu meningkatkan akurasi pencatatan, efisiensi proses, dan memberikan visibilitas operasional secara menyeluruh.

Abstract

The increasing electricity demand in Indonesia encourages the development of sustainable and environmentally friendly renewable energy sources. This study aims to analyze the electrical energy potential of a solar–wind-based Hybrid Renewable Energy System (HRES) through the integration of Solar Power Plants (PLTS) and Wind Power Plants (PLTB). The research method includes literature study, solar irradiation and wind speed data collection, HRES system design, and system performance analysis. The proposed system consists of a 300 Wp monocrystalline solar panel, a 300 W wind turbine, a 12 VDC 60 A hybrid MPPT controller, and a 4 × 20 Ah battery storage system. Solar irradiation data were obtained from Global Solar Atlas, while wind speed data were collected using Windy.com. The results show that the annual electrical energy production potential of the PLTS reached 1,381.2 kWh/year, with the highest production of 128.9 kWh occurring in August. Wind speed at the research location ranged from 1.54 to 4.11 m/s. The integration of PLTS and PLTB generated a maximum output power of more than 550 W and improved the stability and continuity of electricity supply. Therefore, the HRES system has strong potential as a sustainable energy solution for off-grid areas in Indonesia.
