Abstract

Pertumbuhan ekonomi Indonesia yang berada pada rata rata 5,8% per tahun tidak hanya berdampak pada peningkatan kesejahteraan masyarakat secara umum tetapi juga peningkatan kebutuhan tenaga listrik. PT PLN (Persero) telah mengantisipasi peningkatan permintaan tenaga listrik dengan membuat rencana pengembangan pembangkit listrik. Studi ini bertujuan untuk menentukan model transportasi terpadu angkutan gas alam cair (Liquid Natural Gas (LNG)) untuk pembangkit di Kawasan Timur Indonesia. Metode yang digunakan dalam penelitian ini adalah metode optimasi untuk mendapatkan tipe kapal yang sesuai pada rute terpilih yang memberikan biaya satuan minimum. Hasil optimasi menunjukkan bahwa distribusi gas alam cair ke pembangkit listrik di Indonesia bagian timur adalah dengan suplai langsung dari Kilang Tangguh ke pembangkit listrik di Sorong dengan unit biaya sebesar Rp230.000/m³, 6 pembangkit listrik disuplai melalui Hub Ambon dengan biaya satuan sebesar Rp280.000/ m³, 7 pembangkit listrik disuplai melalui Hub Ternate dengan unit biaya satuan terendah adalah tujuan Tidore sebesar Rp230.000/ m³ dan 5 sisanya akan disuplai melalui Hub Manokwari dengan biaya satuan terendah adalah tujuan Biak sebesar Rp340.000/ m³.

Abstract

Indonesia as an archipelago state requires having an adequate connectivity to improve the welfare and the economic balance. Tol Laut programme which has been started since 2016 is a government strategy designed to create connectivity among regions in Indonesia within regular and scheduled shipping especially to Eastern Indonesia and remote island. Tol Laut programme implementation which required the government evaluations is operationl ship planning. The following research is aimed to generate the most optimised ship route evaluation in terms of tol laut by conducting optimization method which is schemed through Multiport and Hub-Spoke trans-portation network. The most optimised tol laut shipping network through South Maluku and Papua (minimum Required Freight Rate (RFR)) is operating the Hub-Spoke operation where the hub port is in Saumlaki. Require-ment of fleets in order to support hub-spoke operational is that one unit of fleet with capacity 296 TEUs, three units of fleets with capacity 60 TEUs and one unit fleet with capacity 87 TEUs by having the potential for 50% subsidy savings compare to year 2018, cut down from IDR 119,21 billion to IDR 59,46 Billion.

Abstract

Passenger ship accidents are complex events that often stem from multifactorial causes, with human error, technical deficiencies, and environmental conditions playing critical roles. Between 2018 and 2022, Indonesia's National Transportation Safety Committee (KNKT) recorded 108 ship accidents, including 29 ro-ro passenger ships and 19 conventional passenger vessels. This study applies the Hazard and Operability Study (HAZOP) methodology to analyze risk factors leading to passenger ship accidents, particularly from a human resource (HR) perspective. Using both primary data (interviews and surveys with crew members) and secondary data (accident reports and maritime literature), the study identifies significant risks including improper use of LPG stoves, unsafe cargo storage, malfunctioning fire detection systems, crew fatigue due to high workloads, and vessel overloading. Results highlight the importance of improving safety training, maintenance practices, and HR management. The findings contribute to enhancing risk awareness and safety strategies among stakeholders in the Indonesian maritime sector.
