Abstract

3D printing technology is an additive manufacturing technology (layer by layer) to create 3D objects with melted filament material. With this 3D printer, users can create a ready-to-use product. This research uses ABS (Acrylonitrile Butadiene Styrene) filament because mechanically this filament is very strong and has resistance to high temperatures. This study aims to find the highest tensile test value from 3D printer printing results with ABS filament specimens, for the factors used are infill layer thickness, wall printing speed, nozzle temperature, bed temperature, print speed, fan speed, infill density, wall thickness, top layers, bottom layers, infill overlap, retraction distance, and retraction speed. Printing is done with the Anycubic 4Max 3D printing machine, while the specimen size is 115 mm x 19 mm x 4 mm. This study uses the Taguchi L16 method with 13 factors and 2 levels printed as many as 48 specimens. So that the tensile test results were obtained with the highest value of 30.46 MPa in the second experiment the lowest with a value of 25.31 MPa in the third experiment. For the calculation of the S/N ratio, the most influential factor is the fan speed.

Abstract

The quality of the welding joint is important in welding. Welding current is one of the factors that affect the quality of the connection. This study aims to determine the effect of SMAW welding current on the impact strength and hardness of ST.37 steel. The variables used in this study are the current variations of 80 A, 100 A and 125 A. The method used is experimental. Based on the impact test data, the 80 A current variation obtained an average impact energy of 193.861 Joules, while the average impact value was 2.423 Joule/mm2. With a current variation of 100 A, the average impact energy is 203.918 Joules and the average impact value is 2.548 Joule/mm2. The current variation of 125 A obtained an impact energy of 203.918 Joules and an impact value of 2,469 Joule/mm2. The 80 A current variation has the lowest average impact value and the 100 A current variation has the highest average impact value. The results of the hardness test for current variations of 80 A, 100 A, 125 A, obtained the highest average hardness value occurs at a current variation of 80 A with a value of 51.00 , while the lowest average hardness value occurs at a current variation of 125 A with a value of 50.279 . Based on the research data, it can be concluded that the variation of the welding current affects the impact strength and hardness.

Abstract

The process of flouring the tubers of taro beneng by Mr. Arizal is still done manually. The dried tubers are pounded using a pestle, then after the results are smooth, filtered using a special filter and if the results are still rough, the mashing process is carried out again. This flouring process takes time and is repeated for a relatively long time. This study aims to design and build a flour milling machine that can produce flour with a mesh fineness level of 0.5 mm and a machine capable of producing flour with a capacity of 10kg/hour. The research method used is the VDI 2222 method, starting with the stages of planning, conceptualizing, designing and completing. Furthermore, the process of making and assembling machines at the Polman Negeri Babel workshop was carried out. Then testing and analysis were carried out to determine the extent to which the results of the design and manufacture of the machine were carried out. Based on the design results, the driving motor uses an electric motor 1 HP 1400 RPM with a shaft diameter of 35mm. The transmission system uses a pulley and belt, the penepung system uses a mono disk system. Based on the test results, the average machine is able to flour beneng taro tubers with a capacity of 11.2 kg/hour with 0.5mm mesh fineness.

Abstract

Coconut fruit has many benefits, ranging from food, drinks, medicine to cosmetics. Almost all parts can be used such as, roots, wood, coconut leaves, shells, young coconut water and coir. Coir is used for brooms and crafts such as flower pots, hangers, bags and others. The process of stripping coconut husk in Bangka Belitung still uses a lot of traditional tools such as: machetes / machetes, large scissors and crowbars, so the process of stripping coconut husk requires a lot of energy, requires a long time, requires special skills and the risk of work accidents. So, in this final project, a coconut husk peeling machine was designed and made by prioritizing work safety, ergonomics and fast in peeling coconut husk. This coconut husk peeling machine uses 2 rollers in the form of a cylinder with 16 plates attached to the peeling pipe, 12 flat plates and 4 jagged plates. The two rollers rotate in the opposite direction aiming to tear the coconut husk. The engine is driven by a 6.5 PK gasoline combustion motor with a maximum rotational speed of 3600 RPM passed by a sprocket chain to the gearbox input with a sprocket ratio of 1:3 rotational speed and the power coming out of the gearbox 1:40, the power coming out of the gearbox output is passed using a chain transmission and sprocket connected by a rolling roller. This machine is able to peel coconut husk with the longest time of 23 seconds and the fastest time of 13 seconds.

Abstract

This final project makes pempek which is the basic material for making kemplang as the object of research. Based on the results of a survey conducted in Kampung Pasir until now pempek slicing is still done manually using a kitchen knife which requires slicing time of about 1 hour for slices weighing ±4.3 kg or 1 minute for slices of 71.7 grams. The purpose of this final project is to design a pempek slicer as many as 4 butts measuring 25 cm long with a diameter of 4 cm and a thickness of 2-3 mm that can be sliced in one slicing process. The design of the pempek slicer into kemplang refers to the VDI 2222 design method. From the experiment, it was found that the pempek slices were uniform in thickness and the tool could slice the pempek within 10 kg/hour.
