Merak Port of Java and Bakauheni Port of Sumatera are connected by ferry lines. However, the number of ferry ships and facilities of the two ports are not able to accommodate the number of vehicles that cross. Queues of vehicles often occur and waiting times at the port are very high and have an impact on the accumulation of vehicles on the road to the port. Anticipating these conditions, it is possible to open a short sea shipping (SSS) route from Ciwandan port to Panjang port as an alternative route for shifting some of the vehicles served by those ferry ships. This research aims to analyze the efficiency of opening the Ciwandan–Panjang SSS route in terms of benefits for stakeholders, cost efficiency for vehicle users, and the potential for CO2 reduction from exhaust gases. We use a descriptive quantitative method. The analytical techniques used include port cost analysis, benefit analysis (for the government and ship operators), comparative analysis of transportation costs, and analysis of the impact of reducing CO2 emissions, which are valued monetarily. The results of the analysis show that the operation of the Ciwandan–Panjang SSS can reduce the total cost of vehicles compared to the Merak–Bakuheni route. Owners of cargo vehicles are able to save on logistics costs of IDR 332 billion per year. Estimated state revenue through non-tax state revenues (NTSI) and value-added tax (VAT) is increased. Losses due to CO2 emissions are estimated to be reduced, with a value of up to IDR 511 billion per year.
The implementation of the safety management system (SMS) in traditional shipping in Indonesia, known as “Pelra”, has not been implemented. The nature of the operation pattern and characteristics of Pelra, which are still traditional (non-convention), means that international maritime rules such as SOLAS, MARPOL, LLC, Collreg, and STCW, as well as Indonesian government regulations related to shipping safety, are not suitable for Pelra. As a result, Pelra ship accidents continue to occur every year in Indonesian waters without any efforts to deal with safety management. The aim of this study is to find indicators to assess the implementation of Pelra’s SMS that adopt the specific characteristics of Pelra sea transportation. The analysis was conducted with a Delphi approach, based on expert opinion in the field of ship safety, which was tested using non-parametric statistics (Kendall’s W test). The consensus results obtained 9 factors described in 44 assessment indicators to implement SMS on Pelra vessels. Several new indicators were found, including indicators related to ship stability, ship construction, and safety and navigation equipment. The level of expert agreement from the concordance W coefficient value is in the range of 0.3 (moderately strong) to 0.7 (very strong), which suggests that these findings are valid and feasible to be used as assessment indicators in order to implement SMS Pelra.
The development of red boxes for motorcycles in Indonesia was initially adopted from the advanced stop line (ASL) for bicycles. The bike box concept was adopted for motorcycles in Indonesia. To date, red boxes have been fully implemented in 21 cities in Indonesia. The purpose of this study is to analyze the effect of traffic light countdown timers and motorcycle lanes as an approach to the red box for motorcycles at signalized intersections. There were four locations studied in Denpasar Bali, i.e., red boxes with countdown timer only (Condition 1), red boxes with motorcycle lane only (Condition 2), red boxes with countdown timer and motorcycle lane (Condition 3), and red boxes without countdown timer and without motorcycle lane (Condition 4). The analysis results based on motorcycle volume data indicate that a countdown timer has a significant effect in increasing motorcycle acceleration when the green light starts, reducing the possibility of motorized vehicles other than motorcycles stopping in the red box area and reducing stop line violations while waiting during a red light. Meanwhile, the presence of a motorcycle lane as an approach lane to enter the red box area has a significant influence on increasing the occupancy of the red box by motorcycles. In addition, the correlation test shows that the countdown timer has a strong correlation with the occupancy of the red box to capacity and to stop line violation. Meanwhile, the level of traffic flow is strongly correlated with the countdown timer and motorcycle lane.
