Abstract

The use of modern machinery and installations and hazardous materials is increasing. In addition, a work environment that does not meet the requirements for occupational safety and health, hazardous work processes and nature, as well as an increase in the intensity of the operational work of the workforce, affects the increase in the number and seriousness of work accidents. The type of research used is descriptive quantitative research so that the data entered are in the form of words, sentences and pictures, which are then scored to determine the level of danger before carrying out the work. In conducting a job safety analysis, what is done is to determine the work to be analyzed, divide the work into several work steps or standard operating procedures, identify potential hazards, risk assessment, evaluate risk and determine the level of risk and prevention. The assessment of the risk value analysis on replating work has a value of up to 8, indicating the need for control measures in the process. Then the coating work on the fuel area and main deck also have a risk value of 8, so it is also necessary to take control measures on the coating process in that area.

Abstract

Cathodic protection is a thermodynamic corrosion rate control method by treating metal structures as cathodes. Cathodic protection is very important to reduce the corrosion rate of the underwater surface area of ​​the hull plate. This protection is affixed to parts of the ship that are susceptible to seawater corrosion, more precisely located below the water line. Most of the damage to the ship's steel construction plate is caused by the corrosion process. As a result of this corrosion causes substantial material losses, so protection is needed to prevent corrosion by using cathodic methods. Basically, corrosion control methods can be grouped into two groups, namely kinetic methods and thermodynamic methods. In the kinetic method of controlling corrosion, it is done by providing barriers to the interaction with the environment so that the corrosion rate can be reduced, but the tendency for corrosion to occur itself is not resolved, so that if the obstacles are removed corrosion will take place again soon. The application of cathodic protection is often combined with coatings. Its purpose is to protect the steel when the coating is damaged

Abstract

The Ampel River is one of the rivers located in Landangan Village, Kapongan District, Situbondo Regency. This river is used by the community to irrigate rice fields, fishing, and so on. The existence of PT. Panca Mitra Multiperdana Tbk. namely producers of processed shrimp around the river have an impact on the quality of the river water. This study aims to analyze the water quality in the Ampel River. The analysis was carried out using the river pollution index method based on the Decree of the Minister of the Environment of the Republic of Indonesia number 115 of 2003. The Ampel River as the research area is drained by a sewage pipe from processed shrimp and is close to local shrimp ponds. Data were collected in situ using 150 ml dark glass bottles and 600 ml clear bottles, stored in a coolbox. The research location is divided into 3 sampling point locations. The results showed that the analysis used the pollution index in the Ampel River, namely at Station I of 2.59, station II of 4.29, and station III of 4.52 where all three were categorized as lightly polluted.

Abstract

Motion sickness on ships is also known as seasickness. It is a symptom of illness caused by the movement of the vessel, which results in uncomfortable physical symptoms characterized by difficulty breathing, dizziness, nausea, paleness, and vomiting. The main cause of seasickness is the absence of similarity of excitability or conformity between the stimulus, eye, and ear labyrinth the human brain receives. The direction of the waves is very influential on the stability of the ship being boarded or not. The research method uses ship motion software simulation. The study results concluded that the vessel's condition was stable, indicated by the waves coming from the 0° or the ship's state sailing in the direction of the incoming waves. Thus, it is predicted that no passengers will experience motion sickness. Meanwhile, the unstable condition of the ship is indicated by the ship with a wave direction of 180° or the state of the vessel sailing in the opposite direction to the direction of the wave. So it is predicted that passengers will experience seasickness after 2 hours of travel.

Abstract

Calculation of ship resistance can be done using mathematical calculations. The value of the ship's resistance is needed to determine the power of the ship's main engine, which is formed from the shape of the hull itself. This research is designed to obtain a model using naval architecture software. From the cargo ship model, it will then be calculated to produce the required value of resistance and ship power. The method used in the calculation uses the Compton Method. The maximum speed of the cargo ship is 12.5 knots, resulting in a resistance value of 309.8 Kn with a power of 2671,370 Hp.

Abstract

The main propulsion engine (MPU), or the main motor on board, is a machine that functions to move the ship forward and backwards. The MPU has two combustion air intake systems in the cylinders, namely a suction intake system that relies on the vacuum of the combustion chamber due to piston movement or a press intake system, namely by equipping the engine with a Turbocharger. The primary purpose of a turbocharger is to increase the combustion air pressure by compressing the air so that the mass of air entering the combustion chamber becomes higher than atmospheric air. If the mass of the combustion air flow decreases due to various conditions, it will affect the incomplete combustion process, which can be visually indicated by darker smoke. Incomplete combustion will affect the power and performance of the diesel engine.
