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

Tarabunga Pier is a pier located in Palipi District, Samosir Regency, North Sumatra Province which serves the Tarabunga – Tamba route. In organizing crossings, tariffs greatly influence the level of transportation services, especially in fulfilling community services. However, the tariff for the Tarabunga-Tamba route currently in effect is not in accordance with Minister of Transportation Regulation Number PM. 61 of 2021. This research aims to determine the ship operational costs (BOK) for the Tarabunga-Tamba route based on Minister of Transportation Regulation Number PM. 61 of 2021. The research methodology used is direct observation in the field, interviews, documentation and literature/institutional studies. Then, to analyze it, we are guided by Ministerial Regulation Number 61 of 2021 concerning Management of River and Lake Transportation. The analysis used is load factor analysis, ship operational cost analysis and unit rate analysis. The results of this research are that the rates set are not in accordance with the results obtained by researchers based on the calculation of ship operational costs (BOK), namely IDR 1,000/passenger and IDR 3,000 /motorcycle. The tariff for the Tarabunga – Tamba route currently refers to Regent Regulation Number 49 of 2017 (Horsik – Ajibata). This is not relevant because the track distance is different. Meanwhile, based on the Ability to Pay calculation of Rp. 2,733 and Willingness to Pay Rp. 1,008.

Abstract

ASDP Ferry Port Bitung Branch is one of the ports located in North Sulawesi Province, precisely in Bitung City. This port has an important role in Bitung City, namely as an access for crossings between islands and provinces in the Sulawesi region. Currently, ASDP Ferry Port Birung Branch has not implemented a zone system in accordance with applicable regulations which has resulted in sterilization at the port and irregularities in the flow of passenger and vehicle traffic at the port. This is because the facilities in Zone A1, namely the ticket machine at the port gate, are still not functioning so that unauthorized vehicles can enter the port at will, the weighbridge is not functioning so that ships with excess loads can still board the ship and the toll gate is not functioning as a place to sell vehicle tickets so that drivers must get off first to buy tickets in the waiting room and there is no special lane for passengers who will get on or off the ship. The analysis of the problem then used an analysis guided by the Regulation of the Minister of Transportation Number 91 of 2021 concerning Zoning in Port Areas Used to Serve Ferry Transportation and the Decree of the Director General of Land Transportation Number SK,242/HK.104/DRJD/2010 concerning Technical Guidelines for Crossing Traffic Management as a guideline for the analysis of the addition of supporting equipment for the zoning system and flow patterns referring to the Regulation of the Minister Number 13 of 2014 concerning Traffic Signs. Based on the results of the analysis above, in order to create a safe and orderly crossing port, the ASDP Ferry Port, Bitung Branch can determine the zoning system and regulate the flow patterns of passengers and vehicles at the ASDP Ferry Port, Bitung Branch, in this case it is also necessary to add facilities and restore the function of several facilities such as Tollgates and weighbridges
