Abstract

Technology 3D printing is also known as Additive Layer Manufacturing. One of the most well-known 3D printing technologies is Fused Deposition Modelling (FDM). The working principle of FDM is by means of thermoplastic extrusion through the nozzle at the melting temperature then the product is printed perlapis layer. This research filament used is ABS (Acrylonitrile Butadiene Styrene) because mechanically this filament is very strong and has resistance to high temperatures, for the factors used namely Infill Layer Thickness, Printing Speed, Wall Thickness, Print Temperature, Bed Temperature, Fan Speed Wall Printing Speed, Infill Overlap, While in this study the method used is Taguchi and this study has the aim to get optimal process parameters on Printing impact tests were conducted with a 3D printing machine Creality Ender 3 printed as many as 81 specimens. Then the impact test was conducted so that the average score of the highest impact test result was in experiment number 27 with a value of 0.00392 joules and for the lowest impact test value was in experiment number 1 with a value of 0.00291 Joule.

Abstract

In the Sungailiat area, there are many SME (small and medium enterprises) culinary types, one of which is processed fried onions. Yuliana's mother is the owner of a fried onion business called "Bagor BTN". Every day 10 kg of shallots are peeled to produce fried onions, even up to 60 kg on holidays. To peel 10 kg of red onions takes about 3-4 hours. So far, the red onion peeling process is still done manually, namely by peeling it using a knife. The purpose of the design of this shallot skin peeler machine is to be able to peel 80% of the onion skin with a capacity of 10 kg/hour by using a peeler and a rubber peeler. The research method used is Method 3E (ECO-EFE-EFI) according to Dieter & Schmidt. The test results of the onion peeler machine that have been carried out show that 90% of red onions are peeled as much as 3 kg in one process within 10 minutes, so that in 1 hour they are able to peel 18 kg/hour onions.

Abstract

Taro Beneng (Xanthosoma undipes) is an abbreviation of large and koneng which means large and yellow which has prospects as an alternative food ingredient other than rice which is included in the type of tubers. This plant thrives in the Bangka Belitung area and has an economical selling value, one of which is taro leaves. Taro leaves can be used as raw material for making tobacco cigarettes. The processing of taro leaves by Mr. Arizal is done by chopping beneng taro leaves using a chopping machine with a thickness of 1.5-2 mm. This is still not in accordance with market demand that wants a thickness of 0.5–0.8mm. This study aims to design and build a taro leaf slicing machine with a thickness of 0.5-0.8 mm with a capacity of 5 Kg/hour. The research method used is using a synthesis system in view of combining design ideas with the stages of clarifying and translating the client's wishes. Then these desires are represented so that they can be brought into the process of designing machines, making choices, analyzing choices and the interrelationships between competing options, assessing the trade-offs in them and evaluating them. Based on the design of the taro beneng leaf slicing machine, the results obtained are the machine is capable of slicing leaves with a thickness of 0.5 - 0.8 millimeters with an average slicing result of 0.75mm. The cutting capacity of the taro leaf slicing machine is 4.8 kg/hour or only 53% which can be sliced ​​from an average of 230 grams in an effective scale.

Abstract

3D Printing or additive manufacturing is a new technology for the industry. The machine has created an object for 3D layer by layer that makes a product with accurate dimensions and certain patterns, as the technology developed, the manufacturing industry began to develop products using additive material methods known as rapid prototyping or layer manufacturing, one of which was the use of 3D printer technology. This research was conducted on a 3D Printing FDM model Ender 3 Pro with dimensions 220 mm x 220 mm x 250 mm and using a nozzle with a 0,4 mm diameter. The material for this research is Nylon 6 with a diameter of 1,75 mm with variations in Layer Thickness (0,21 mm 0,24mm 0,27 mm), Infill Pattern (Rectilinear, Grid, Wiggle), Z-Orientation (0°,15°,30°) which will be determined in Ultimaker Cura 4.4.0 software and Taguchi Method in software minitab19.1. resulting in OA L9 with 3 times replication printed sample. The results obtained after testing the highest bending stress values are found in the 9th specimen which is 16,7 MPa average with 0,27 Layer Thickness, Wiggle Infill Pattern, and 15° Z-Orientation. While the lowest bending stress values are found in the 4th specimen which is 12,7 MPa average with 0,24mm Layer Thickness, Rectilinear Infill Pattern, and 15° Z-Orientation.

Abstract

The demand for clean water continues to increase along with population growth. Therefore, it is important to improve water quality to meet the demand for clean water supply. There are three methods that can be used in the water purification process, namely filtration, sedimentation, and adsorption. Clam shell waste contains calcium carbonate (CaCO3) with a percentage of 98%. This content can be used as an adsorption media. The purpose of this research is to utilize gold snail shell waste for activation at mesh size and temperature by determining the most optimum value. The results of making adsorbents will be tested on borehole water at the Bangka Belitung State Manufacturing Polytechnic to study changes in the degree of acidity of water pH. The research was conducted using the Taguchi method, where the process parameters were mesh size and activation temperature. The parameters were then adjusted with the OA L_9 algorithm for three repetitions. Based on the results of the research and test data processing that has been done, it is concluded that the activation temperature is the highest influence in the process of making adsorbents. Optimal results were obtained at a powder size of 150 mesh (109 μm) and at an activation temperature of 700o C. With a percent contribution value on mesh size of 3.42% and activation temperature of 94.32%. It can be concluded that activation temperature is the highest influence in the process of making adsorbents.
