Abstract

Casting is a manufacturing process that uses molten metal and molds to obtain a product that is closer to its final geometry. The quality of casting products is influenced by several factors and one of the important factors is the mold. The sand that is often used in making molds is resin coated sand, since this sand will bond to one another if it is heated. The research focus is determine the effects of grain size and heating temperature of resin coated sand on the mechanical properties of the mold which include compressive, shear and tensile strength. This study used an experimental method with large parameters of resin coated sand and heating temperature. From the test results, the highest compressive, shear and tensile strength values are Produced by sand with grain size less than 300 µm are identified.. The high heating temperature makes the bonds between the sands stronger and the strength value is higher..

Abstract

Planer bamboo machine V2 is a machine used to flatten the top and bottom surfaces of bamboo slats. This machine was made to overcome problems with existing machines in the form and long times of drawstring. An inverter is added to set the rotational speed roller. This study analyzes the effect of a combination of the top and bottom cutting speeds on the rotation speed of roller whose rotation speed was set at frequencies of 10, 20, 30, 40, and 50 Hz. The purpose of the study is to determine the effect of inverter frequency settings on the results of bamboo drawstring. Based on the analysis performed, the appropriate combination for the performance planer bamboo machine is by setting the inverter frequency to 20 Hz with a production result in a day of 54,54 slats drawstring with long of slats 2 meters, with a total power consumption of 2,483 kWh in one hour.

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.
