Abstract

Rice husk waste, often produced by the rice milling industry, creates a problem. To utilize rice husk waste, one of the uses is to make a product in the form of particle board by heating and pressing with a hot press machine. This study aims to design and build a hot press machine to make a rice husk particle board with a press using a pneumatic system. The method for making a hot press machine is by making a machine design, load calculations, and static simulations on the frame, then manufacturing using a fabrication and assembly process. The results of the design and manufacture were obtained with machine dimensions of 1372x800x700mm, maximum heating temperature of 175oC, a pneumatic system using two double-acting actuators, von Misses stress results from an even load of 143 N on the frame, obtained a von Misses stress of at least 2.405e-1N/m2 and The maximum Von Misses Stress of 1.856e6N/m2is still a safe limit because above the yield strength value of the material used, the maximum displacement value is 1.098 mm. The safety factor is 2.01.

Abstract

The purpose of using natural fibers as reinforcement for composite materials is expected to be an alternative material to replace the used of fiberglass fibers and is expected to be able to increase the quality of water hyacinth fibers and coconut coir fibers. In this study, to determine the best tensile strength value, several experiments were carried out using the determine factor of the fiber volume fraction of 20%, 25%, 30% and the immersion factor with NaOH solution for 4 and 6 hours using a matrix in the form of epoxy resin. The test results showed that the variation of soaking in alkaline solution media (NaOH) for 6 hours with a volume fraction of 30% obtained the best tensile strength results with each type of fiber, water hyacinth fiber obtained the best results of 23.32 MPa while coco fiber the best result was 22.10 MPa.

Abstract

Current leakage in parallel gap single-sided double spot welding tools occurs if the insulation to the mass-body, either from the work table or the drive system, can reduce the current concentration and result in double-sided welding being relatively difficult to carry out or the weld results being poor. Therefore in this research, an experiment was carried out to test the machine how big the effect of leakage current is on the quality of welded joints by comparing the strength of the joint between a system without insulation and a system using insulation using the independent sample t-test statistical method with a confidence level of 95%. The results of the study show that overall the max load for CT 3 to 10 is a mean difference between without and with insulation, although it is not very significant, this is because the shear test data from the group without insulation has quite a high deviation. High deviations also occur in the upper yield data, the strongest conclusion is that providing insulation (or preventing leakage current) provides a more consistent welding result as seen from the results of the shear test data. Only CT 3 has a significant impact on both max load and upper yield.

Abstract

Separating rice and bran, moving rice to storage, and other processes related to moving grain or rice. In the modern rice milling industry, the process of transferring grain material already uses a pneumatic conveying system; a vacuum blower system for transferring grain is needed when milling grain to become rice. The research method used to obtain the shape of a vacuum blower with strong inlet suction power and outlet thrust is carried out by Computational Fluid Dynamics simulation and testing several types and variations in the number of blades. Simulation of forward curved blade type impellers, backward curved blade, and straight radial blade with variations in the number of 8, 10, and 12 blades. From the impeller simulation, it was obtained that the straight radial blade with 8 blades was the best. The best impeller types were made using the manual method. Measurement results were on the straight radial blade type impeller with 8 blades, with a motor speed of 1,000 rpm; the results of measuring air speed at the inlet were 34.95 m/s and at the outlet 23.08 m/s. In addition, the difference in the results between in simulation and the experiment is due to the fabrication process and air leaks.

Abstract

Community Service entitled Empowering Jaranan Nganjuk Performers in Handling Injuries Through Massage Therapy Skills has a fundamental goal of implementing it in society, namely welfare by always maintaining health by maintaining physical condition. Jaranan actors need to be empowered so that their standard of living and vitality are better. So, through this service, you can make a good contribution, because the main purpose of carrying out this service is so that the actors can be independent in dealing with minor injuries or serious injuries during or after the show. Empowerment is carried out in the form of 1) Involvement of partners as training participants in massage therapy for injuries, 2) Involvement in handling injuries through massage therapy skills, 3) Involving other Jaranan actors to be empowered to have massage therapy skills, 5) Involvement in forming therapeutic massage groups to Jaranan perpetrators. The main goal is for practitioners of the Jaranan Art to understand the benefits, techniques, and practices of this therapeutic massage. Next is to provide legitimacy for Jaranan performers who are proficient at performing therapeutic massage in the form of certification that each Jaranan performer has the skills to handle Jaranan performers when they are injured.

Abstract

WAAM products produce a relatively rough and less precise final surface. Therefore, this study investigated and analyzed the geometric dimensions of the product at each layer and cycle time to achieve N-layers with the aim of obtaining a baseline operational time and achieving WAAM dimensional accuracy of less than ±1 mm deviation. The dimensional measurement method was carried out using a Dinolite photograph, 3-D scanning, and vernier caliper. The cycle time or downtime during the WAAM process was 130 minutes for TS 200 mm/min. TS 200 produced the most consistent thickness with the lowest thickness standard deviation of ±0.49 mm, the highest material efficiency with 45.7% of the material becoming product, and 54.3% of the material being wasted. The product produced by TS 200 mm/min has dimensions of 85 × 4 × 20 mm³.

Abstract

Wire arc Additive Manufacturing (WAAM) is a technology capable of manufacturing large and complex components using aluminum alloys. This is due to its high deposition rate and efficient material utilization. However, WAAM faces several issues, particularly regarding process stability. In the WAAM process, especially when using Gas Metal Arc Welding (GMAW), stability is largely determined by controllable process parameters such as travel speed and arc length. This study aims to clarify how fusion stability, influenced by travel speed and arc length, affects the resulting deposit geometry and heat accumulation. The experimental method involved conducting a single-layer WAAM process using GMAW, with ER5356 filler (diameter 1 mm) and AA6061 substrate. During the single-layer WAAM GMAW process, the heat temperature and current were measured in real-time on the deposits. The results included minimum and maximum height and width measurements of the deposits produced. It was observed that increasing the travel speed reduced the current, thereby lowering the heat input. Heat accumulation, under fixed parameters of 80 A current, 16 V voltage, and varying travel speeds and arc lengths, fluctuated throughout the process. At an arc length of 6 mm, the single-layer deposit geometry exhibited humping, causing irregular widths and heights. Overall, both travel speed and arc length played significant roles in determining the maximum and minimum heights of the deposits.
