Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pelayanan jasa Laporan Kedatangan dan Keberangkatan Kapal (LK3) terhadap peningkatan jumlah kedatangan kapal Ro-Ro (Roll-On/Roll-Off) di Pelabuhan Tanjung Perak. Pelayanan LK3 merupakan komponen krusial dalam proses clearance in dan clearance out kapal yang memengaruhi kelancaran arus logistik dan efisiensi operasional pelabuhan. Penelitian ini menggunakan pendekatan kuantitatif dengan metode analisis regresi linear sederhana. Data diperoleh melalui penyebaran kuesioner kepada 65 responden yang terlibat langsung dalam pelayanan LK3, seperti petugas pelabuhan dan operator kapal. Hasil analisis menunjukkan bahwa pelayanan LK3 berpengaruh positif dan signifikan terhadap jumlah kedatangan kapal Ro-Ro, dengan nilai koefisien regresi sebesar 0,587 dan tingkat signifikansi sebesar 0,000 (p < 0,05). Temuan ini mengindikasikan bahwa peningkatan kualitas pelayanan LK3, termasuk efisiensi waktu, keakuratan jadwal, dan kepuasan pengguna jasa, secara langsung mendorong peningkatan trafik kapal. Selain itu, implementasi sistem digital Inaportnet turut memperkuat efektivitas layanan melalui integrasi antarinstansi. Studi ini menegaskan pentingnya optimalisasi pelayanan administratif dalam mendukung kinerja pelabuhan serta memperkuat daya saing sektor maritim nasional.

Abstract

This research aims to design and develop a prototype wave power plant that utilizes the vertical motion of a buoy as a source of mechanical energy, which is then converted into electrical energy using a recoil starter mechanism. The system is designed to be installed at the stern of a prototype ship. The vertical movement of the buoy caused by ocean waves is transmitted to the recoil starter through a drive rope, producing a stable one-way rotational motion. This rotation is further transmitted to a gearbox to increase rotational speed before driving a DC generator. The electrical energy generated is stored in a 12 VDC battery, supported by a buck–booster converter to stabilize the output voltage. This study employs an experimental engineering approach to evaluate system performance based on empirical test data. The main components of the system include a buoy as a wave energy collector, a recoil starter as the initial rotating mechanism, a DC generator as the electrical energy producer, a buck–booster converter as a voltage regulator, a 12 VDC battery as an energy storage unit, and a monitoring system based on an ESP32 microcontroller integrated with a PZEM-017 sensor. Experimental results show that the recoil starter operates effectively in driving the generator under both no- load and buoy-loaded conditions. Increases in generator rotational speed are directly proportional to increases in output voltage and current. The PZEM-017 sensor demonstrates a high level of measurement accuracy, approaching 100% when compared with a multimeter. Overall, the proposed wave power generation system functions reliably and shows potential for further development as a small-scale alternative renewable energy source.
