Abstract

This study aims to analyze the technicalities of public shipping from the aspects of ship construction and stability, to analyze non-technical factors that cause accidents, to find efforts to improve shipping safety in supporting policies and strategies related to the roadmap to zero accidents. The research method used to calculate stability and strength is a quantitative empirical method equipped with interviews and questionnaires. The research locations are Makassar, Jakarta, Semarang, Surabaya, Kupang, Sampit, and Jambi. The sample for the empirical method is the ship 100-150 GT which predominantly has an accident, while for interviews and questionnaires used 140 respondents. Data were analyzed by factor analysis and SWOT. The results showed that the vessel stability arm, stability arch area, and metacentra height (MG) met the criteria of the International Martim Organization (IMO) and were above the required conditions. Phinisi fleets are seaworthy from the aspect of stability. Ships have high feasibility to sail. The factor analysis found seven non-technical factors, namely duties and responsibilities, competence in the field of human resources in the field of ship safety, company commitment, shipping navigation equipment, crew competence, ship maintenance and loading systems, as well as recruitment and training. Therefore, the strategy to improve safety includes intensifying the ship skills and maintenance training program, improving shipbuilding quality standards, performance of ship navigation facilities, and seeking to implement technical standards for ship safety.

Abstract

On the Ajibata-Tomok route, there are still vehicles and passengers that are not loaded onto the ship, so that service users must wait for the next departure. This can certainly be detrimental to service users, for example for service users who bring vehicles containing logistics for Samosir Island, where if there is a delay it can disrupt the economic activities of Samosir Island. Therefore, this study aims to determine the ship load factor, efficient operating patterns and departure schedule planning based on the number of ship trips. This study is quantitative with a calculation formulation that is analyzed using several load factor analysis methods, passenger and vehicle growth prediction analysis using the arima method, ship frequency analysis, and scheduling analysis. Based on the analysis results, the departure load factor on the Ajibata-Tomok route for passengers is 30% and vehicles is 95%, lay over time is 48.58 minutes, and the current ship round trip time is 203.96 minutes. The frequency of the existing fleet is 2 ships with 12 trip departures/day, making the ship schedule serving the Ajibata-Tomok route still inappropriate. So a scheduling plan is designed according to the needs of service users, namely 5 trips/ship/day and an additional ship fleet is needed to become 3 ships. The results of passenger and vehicle growth forecasts show that productivity will continue to increase by 44% each year. Planning an efficient ship departure operating pattern can reduce the ship load factor.
