Abstract

The cutter planer is one of the main components of a bamboo planer which functions to flatten the surface of the bamboo blades. The cutter planer has a problem, namely the maximum stress is not known due to the complexity of the components which is difficult to analyze using the mechanical equation calculation method, so that to overcome this problem a numerical method is used, namely the finite element method. In this study, an analysis was carried out on a cutter planer by comparing the process of cutting bamboo slats with two directions of rotation clockwise (CW) and counterclockwise (CCW). The material used in the cutter planer is HSS and bamboo material with petung bamboo. The results of this study show that the highest maximum stress distribution for the cutter occurs in CCW and the lowest maximum stress distribution for the cutter occurs in CW.

Abstract

Solid welding has always been concerned with probe design, pins, and joint strength. Many researchers have conducted studies on joints, such as butt joints, lap joints, and T joints, but the results show low strength. This study analyzes the mechanical properties of a new design of a 90o angle joint joined by friction stir welding. This study connected aluminum 6061 using the friction stir welding method using a rectifying jig and a probe with EMS 45 material. The corner joint designs used corner-lap 45 with feed rate as independent variables in 6, 8, 10, 15, and 30 mm/min and dependent variable probe rotation speed at 1000 rpm and shoulder pressure in 584 kg. The results show low feed rates create chips and fish fins on the advancing side, and microstructure test results at low feed rates (6-15 mm/min) indicate the presence of interface bonding. The hardness value of the stir zone also shows an insignificant increase. In the tensile test results, the tensile strength decreases from the base metal value, which then the tensile strength increases along with the increase in feed rate up to a feed rate of 15 mm/min and decreases again at a feed rate of 30 mm/min.

This research aims to identify the causes of material failure in the flywheel housing of diesel engines used in dump trucks in corporate sectors such as mining, plantations and infrastructure in Indonesia. Through mechanical testing which includes visual observations, tensile, impact and hardness tests, as well as microstructural observations and chemical composition analysis, this research found that the flywheel housing material has brittle properties. The test results show the highest tensile strength of 23.021 MPa, the average impact value of 0.0417 J/mm2, and the average hardness value of 106.708 VHN. The microstructure of the flywheel housing material is dominated by the Al-Si alloy element, which makes the material tend to be brittle. Several factors that can cause cracks in the flywheel housing include the work environment, material properties, lack of maintenance, and operational errors.

Abstract

Waste is a byproduct of production activities, both in the industrial and household sectors. Solid waste, commonly known as garbage, can be divided into organic and inorganic waste. Organic waste from households, such as food scraps and plant materials like wood, twigs, or leaves, can be converted into compost or organic fertilizer that has economic value. The process of organic waste treatment requires a mixer machine to blend the chopped waste with other additional materials. In this study, the design and construction of an organic waste mixer machine were carried out. The mixing mechanism uses two ribbon-shaped twisted (helical) blades that rotate in opposite directions. As they spin, they produce a rotating movement while shifting to the left and right, creating a more even mixing effect. The shaft and mixing blades are rotated by the main drive, a 1 hp single-phase electric motor with a speed of 1420 rpm. From the electric motor, the speed is reduced using a speed reducer gearbox with a 40:1 ratio, bringing the shaft and blade rotation speed to 35,5 rpm. The mixing force generated on the mixer blade is 752,6 N.

Abstract

The utilization of bamboo in architecture and construction as an eco-friendly alternative to wood is steadily increasing. While ovens are crucial tools in the production of laminated bamboo, particularly for heating during the bonding process, research on ovens specifically designed for bamboo lamination remains scarce. This study aims to optimize the design of laminated bamboo ovens using Computational Fluid Dynamics (CFD) simulations to achieve uniform heat distribution and maximize thermal efficiency. Three design iterations were tested: Iteration 1 with an air velocity of 4 m/s, Iteration 2 with 1.5 m/s, and Iteration 3 with 3 m/s. The results revealed that Iteration 1 exhibited uneven heat distribution, with initial temperatures reaching 1175 K before dropping sharply to 800 K. Iteration 2 showed slower initial heating, achieving a final temperature of 360 K, but heat distribution remained suboptimal. Iteration 3 delivered the best performance, achieving uniform and stable heat distribution near the target temperature of 473 K (200 °C). Overall, Iteration 3 demonstrated the most efficient thermal performance, not only meeting the target temperature with consistent heat distribution but also enhancing the overall heating efficiency of the oven.

Abstract

Bamboo is recognized for its eco-friendly attributes and rapid growth, serves as a promising sustainable alternative to wood. However, the high production cost of laminated bamboo remains a major challenge due to labor-intensive processes, particularly manual splitting, which affects efficiency and labor costs. To overcome this issue, this study presents an automated bamboo diameter measurement system that leverages Canny Edge Detection and Hough Transform to ensure precise and uniform slat dimensions. A dataset of 100 bamboo images with diameters ranging from 11 - 13 cm was utilized for training and testing. The system achieved a high accuracy, with a coefficient of determination (R²) of 0.973, demonstrating strong predictive reliability. Furthermore, Bayesian Optimization was applied to fine-tune parameters, resulting in an optimized configuration for both Canny Edge Detection and Hough Transform. The proposed system reduces dependence on manual labor, thereby lowering production costs and improving overall manufacturing efficiency. Automation in the bamboo splitting process ensures consistent and precise slat dimensions, supporting scalability and enhancing the economic feasibility of laminated bamboo production. The findings of this study provide a practical and sustainable solution to optimize production, making laminated bamboo a more viable and competitive material in the industry.
