This study was a true experiment. The dependent variable was cocopeat mass. The independent variables were blade density, consisting of σ1 (84/210π), σ2 (42/210π) and σ3 (21/210π). For each variation of the independent variable was conducted 10 experiments. The study sample was 30 pieces of coconut coir. The mass of each coconut coir was 50 grams.

Vibration analysis needs to be done to ensure the durability of the ship's construction. Ship construction that is unable to withstand the vibrations it experiences is at great risk of structural failure. Vibration on the ship is also something that can only be suppressed and cannot be completely eliminated. The objectives to be achieved in this final project are to get the value of the ship's resistance and get the root-mean-square value of the maximum vibration speed that occurs on the ship. The calculation of the value of the ship's resistance is carried out using the Holtrop resistance calculation method, while the determination of the root-mean-square maximum speed of vibration is carried out using the Ansys Workbench. The resistance value obtained on this ship is 7,165 kN. The root-mean-square value of the greatest maximum vibration velocity occurs at a frequency of 47.2 Hz at 76.71906943 m/s. Due to the limit value of r.m.s for aluminum vessels is 15 mm/s, then the value of r.m.s at a frequency of 47.2 Hz that occurs on ships does not meet class standards.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72857390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The waste is in the form of motorcycle components such as wheels, tires, drums, canvas, gear, chains and pistons and many others. Until now, the community has not used this waste, especially the use of used pistons as raw material for casting connecting rods. Connecting rod itself is a motorcycle component made of aluminum. In this study, the authors wanted to analyze the physical and mechanical properties of the casting (imitation) connecting rods made from used pistons with the addition of Titanium Boron (Ti-B) elements. The characterization of the casting results was analyzed by observing the microstructure and Vickers hardness test. The results showed that the physical properties of the foundry material contained 81.6% aluminum and 13.09% silicon, while on microstructure observations with a magnification of 100x, the Al phase and Al-Si alloys were more dominant. In the Vickers hardness test, the hardness result was 79.59 VHN.

Aluminum alloys have excellent mechanical properties, including corrosion resistance, lightweight, and good formability. However, in addition to these good properties, aluminum also has a weakness, namely the appearance of porosity and cracks when connected using arc welding (TIG, MIG). Friction stir welding (FSW) is an appropriate welding method for aluminum alloys to overcome these weaknesses, but the next problem will arise, namely related to distortion, decreased mechanical properties, and residual stress. For this reason, additional treatment is needed in order to improve the mechanical properties of the FSW welding results. The research method to be carried out is to carry out the FSW welding process on 2024 T3 aluminum alloys by adding moving local heat or transient thermal tensioning (TTT) using a heater placed in front of the tool and a heating temperature of 200°C. Some of the characterizations that will be carried out are microstructure tests, tensile tests, and fatigue tests. The results showed that the highest tensile strength value was obtained in the 1500 specimen, which was 312.2 MPa. The microstructure in the nugget zone (NZ) is fine-grain equiaxed. The lowest fatigue crack propagation rate at ΔK values of less than 7 MPa.m0.5 occurred in the 1100 specimen, while in other specimens the fatigue crack propagation rate was higher.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86291565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The feed water system at the Grati Gas And Steam Power Plant is one of the most important factors, especially in the feed water pump equipment. One of the pumps that is highly reliable is the High Pressure Boiler Feed Water Pump which is used as a tool for supply feed water to the Heat Recovery Steam Generator. However, from the recap data of disturbances in the Grati Gas And Steam Power Plant, leaks often occur in the system, precisely in the line warming up which serves to provide flow to the standby High Pressure Boiler Feed Water Pump and comes from the backflow of the High Pressure Feed Water Header to the Discharge side of the pump. Analysis related to the leak is very necessary in order to minimize losses due to the occurrence of the disturbance using the Root Cause And Failure Analysis method to eliminate the main disturbance causing the leak. The research variables used include the independent variable: regulating the pump discharge opening, the dependent variable: flow rate and valve warming up opening and the controlled variable: standby pump temperature and pump operating temperature. By conducting a series of trials setting the discharge valve opening of the High Pressure Boiler Feed Water Pump starting from 80%, 85%, 90%, 95% and 100%. The results of these tests can be concluded that the greater the opening of the pump discharge valve, the higher the speed and flow rate, while the pump discharge pressure will decrease.","PeriodicalId":31503,"journal":{"name":"Turbo Jurnal Program Studi Teknik Mesin","volume":"4 6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83669810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
