Abstract

Evaluation of the performance of cargo oil stripping pumps on the Mt. Noni T ship is needed for smooth loading and unloading of avtur at PT Pertamina Prata Niaga Integrated Wayame Ambon. Pumps that operate continuously will experience a decrease in work. This can be caused by several factors, namely the age of the pump, and the level of roughness of the pipe that causes an increase in head loss. The purpose of this study is to evaluate the performance of cargo oil stripping pumps on the MT. Noni T. The method carried out in the study uses a quantitative method with 2 variables. The independent variable is the input power and output power of the pump while the bound variable is the efficiency of the pump. The data obtained consisted of primary data and secondary data. The methods used when collecting data are interview, observation, and documentation methods. The result of this study is that there is a decrease in pump efficiency which was initially 100% to 80% influenced by the life of the pump and its operating time. Suggestions that can be given are Conducting periodic inspections of the pump to prevent damage that may occur in the future and Conducting inspections of the pump drive motor so that the pump works properly.Keywords: Screw, pump, efficiency, tanker, Flow.

Abstract

Painting is a process of applying paint in liquid form to an object, to create a thin layer which then creates a hard layer or layer of paint. The function of painting itself is to give a layer to an object so that the object's lifespan can be longer. Attachment of paint to the surface can be done in many ways, wiping, smearing, brushing, spraying, dipping or in other ways. Attachment of paint by spraying is the paint attachment that is most often found in automotive painting workshops. Apart from that, attaching paint by spraying is easier in adjusting the area where painting will be carried out, the results are also good if done correctly. The quality of good painting results is influenced by many factors such as skills, materials used, etc., while determining good painting results is based on several factors, such as surface roughness, gloss power, etc. The hardness of the painting results is also greatly influenced by the percentage of hardener mixture in the paint mixture. The paint in question here is color paint (top coat). This research is to determine the best percentage of clearcoat in the painting process by testing the hardness of the painting results. The results obtained by varying the percentage of the mixture in the best clearcoat are in the percentage variations of 100 (Base): 55 (Hardener) + Thiner or Solvent (10% of Base) is 83.49 H, 100 (Base): 55 (Hardener) + Thiner or Solven (10% of Base) is 82.99 H, 100 (Base) : 45 (Hardener) + Thiner or Solven (10% from Base) is 82.51 H and the lowest is the variation 100 (Base): 60 (Hardener) + Thiner or Solvent (10% of Base) namely 79.57 H. Keywords: Painting, Clearcoat, Hardener and Paint hardness
