3D printing technology is one of the new breakthroughs in the world of manufacturing. This principle uses layered modeling, which directly converts 3D data from computer-aided design (CAD) into physical prototypes. Additive Manufacturing technology itself has attracted a lot of interest as research material from industry to academia because it can provide manufacturing solutions that produce products with complex designs and reduce time without compromising print quality. Currently, the Fused Deposition Modeling (FDM) process is the most widely used process in 3D printing due to its ease of operation, low operating costs and environmental convenience. This study uses the Taguchi method with quality characteristics the bigger the better. The experimental design used is L27 OA by analyzing the Signal to Noise Ratio SNR. The method is based on the principle of tensile strength, to determine the process parameters that greatly affect the ABS CCTREE filament. The process parameters used in this research are nozzle temperature, layer thickness, temperature based plate, print speed and infill pattern. The order of the most influential parameters in a row is layer thickness of 40,74%, print speed of 9,40%, nozzle temperature of 5,69%, temperature based plate of 5,56% and infill pattern of 4,36%.
Rice is one of the basic foodstuffs consumed by the people of Indonesia as well as Bangka Belitung Islands Province more precisely Bangka Regency Riau Silip Village Banyu Asin. Freshly harvested rice is usually still not separated from straw / malai. The process of harvesting rice still uses traditional tools or also called gebotan. The threshing machine available in Banyu Asin has not been able to maximize the results of the platform, which resulted in the length of the threshing process. Based on these needs, it was designed to build a rice threshing machine to facilitate the threshing process. Rice threshing machine design refers to the VDI 2222 method of development which has 4 (four) stages, namely: planning, conceptualizing, designing, and finishing, then assessed based on technical, and economic aspects. The conclusion obtained during the design process of the rice threshing machine is the design of the machine weighing 60 kg lighter than the existing machine is easy to move and the design of the machine whose components are easy to remove installs. The design of a rice threshing machine that is able to knock rice as much as 86.4kg / hour, compared to existing machines is only able to knock rice as much as 30kg / hour.
The growth and development of cattle is very dependent on the maintenance process, including the availability of feed in the surrounding environment, to meet the daily needs of cattle. In order for cow feed to be available and available, it is necessary to have a natural source of cow feed because it is easily available and has a high level of availability, namely in the natural surroundings. This natural source is in the form of grass or leaves that can be consumed directly by cattle, the availability of the feed is not influenced by weather conditions so that it can be obtained anytime and in large quantities. The grass that is available in the environment can be eaten directly by the cows, but the leaves must be processed first to make it easier for the cows to eat. For example, oil palm leaves and fronds, because the size of the palm fronds is quite large, so they cannot be directly used, it is necessary to have a chopping process so that they can be consumed by cows. Of course, the census process manually can be done but it is not effective, it requires a lot of time and a lot of effort. Based on these problems, it is necessary to mechanize the chopping process in order to simplify the process. The purpose of science and technology for the community in cattle breeder farmer groups in general is to increase the quality and capacity of production, especially cattle. Meanwhile, in particular, this IbM activity is expected to collaborate between partners and proposers from educational institutions. Partners can develop their business because they can meet the need for more animal feed through appropriate technology machines in the form of animal feed chopper machines, while institutions can apply science and technology directly and apply their knowledge into appropriate technology and can also introduce Polman educational institutions to the wider community.
Province of Bangka Belitung Islands has a large number of natural resources, including mining products, marine products, agricultural products, plantation products, and river products. One of the river products is fish and giant prawns which have high economic value which can be found in Bangka district, one of the places or rivers in Sempan village, Pemali sub-district. The river fishermen in the Pemali village fish and shrimp traditionally. The problem that occurs in these partners is that the boat still uses oars, this of course greatly slows down the movement in the river so that the catch of fish and giant prawns is small. Survey results on river fishermen partners on Sempan village, Pemali Bangka sub-district obtained data on the demand for a boat propulsion engine with low fuel consumption or a small engine displacement. The purpose of science and technology for river fishing communities is to increase the productivity of the catch of giant fish and prawns and as a means to save themselves from predators (crocodiles) when fishing for fish and shrimp in the river. The specific target of this IbM activity is expected to establish a cooperative and mutually beneficial relationship between partners and proposers from educational institutions. Partners get the right technology in the form of Turbojet Drive, 3D Printing product with a fuel-efficient engine. Agreed to propose to replace the boat propulsion system which originally used wooden oars to be replaced with a special “Turbojet Drive 3D Printing Product” propulsion with a fuel-efficient 58 cc engine. By replacing the offered boat propulsion, it is hoped that the targets and objectives of this IbM can be achieved and the catch of fish and giant prawns will increase. Thus, it is hoped that the standard of living of river fishermen will increase by using the appropriate technology offered by the proposing team.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
