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

One of the components contained in the main motor, which affects the combustion system is the injector. The smog of fuel into the combustion chamber is determined by whether or not the condition of the nozzle on the injector is good. If the middle nozzle is in a state of constraint, the nozzle cannot atomize the fuel optimally. If that happens, the combustion process will also be disrupted and will affect the power of the engine. The method carried out at this KKW uses data collection techniques by direct observation during maintenance and direct interviews from people who know on the ship, with the aim of knowing the cause of the imperfection of the injector fogging process on the main engine on the ship, it will affect the injection and fogging system on the ship. ship so that it can be known what factors are the cause of the problem. Based on the results of research that has been carried out on the KMP. Trimas Laila, it can be concluded that what affects the imperfection of the fogging process on the injector is the clogged nozzle hole and the dripping of fuel at the tip of the nozzle. from this it can result in the engine not reaching maximum speed and irregular exhaust gas which initially reached 360oc to 440oc, after treatment the exhaust gas temperature returned to normal to 360 oc.
