Abstract

The development of technology in the increasingly advanced construction sector cannot be separated from welding, because it has an important role in metal engineering and repair.. There are several factors that affect the quality of welding results, including welding procedures, materials, electrodes, and types of welds used. Inspection of welding results can be done in several ways, one of which is by visual inspection. The TWI Acceptance Criteria standard is used as a reference in determining the quality of welding results in this study. The results of the study showed that four out of five welding defects did not pass the test. This indicates the importance of mastering welding techniques and quality control in the production process. A welder must have competencies that are in accordance with the specifications of his work. Routine inspections and the use of reference standards such as the TWI Acceptance Criteria should be applied to ensure the quality of welding results, both on an educational, training, and industrial scale.

Abstract

This study aims to analyze the effect of depth of cut and feed rate variations on machining time in the C-Axis collet process. The research method employed was an experimental approach using Mastercam software. This study's independent variables were variations in cut depth (0.5 mm, 0.8 mm, 1.0 mm) and feed rate (110 ft/min, 125 ft/min, 140 ft/min), while the controlled variable was a spindle speed of 1036 rpm. The tools used were 8 mm and 4 mm diameter flat endmills. The results showed that the shortest machining time was achieved in Toolpath 2 with a depth of cut of 1.0 mm and a feed rate of 140 ft/min, resulting in a time of 12.47 s. In contrast, the longest machining time occurred in Contour Toolpath 1 with a depth of cut of 0.5 mm and a feed rate of 110 ft/min, taking 141.15 s. This research can be further developed to establish standards for optimizing machining time efficiency in C-Axis processes.

Abstract

This study developed a design for a dough mixer machine for cracker production with a capacity of 5 kg, intended to meet the needs of small to medium-scale production. The machine design incorporates stainless steel for parts that come into direct contact with food and hollow steel for the main frame to ensure both strength and hygiene. The single-phase motor used is tailored to the needs of small and medium enterprises to achieve optimal energy efficiency. The mixing blades are designed with a dual-blade system to enhance dough homogeneity in a short amount of time. The control panel, which includes a simple on/off switch and an emergency stop button, is ergonomically designed for ease of use by non-technical operators. The machine cleaning process is also simplified with a mixing container that can be opened or tilted, supporting cleanliness and speeding up the workflow. This design emphasizes efficiency, safety, and user comfort. The contribution of this research is expected to advance food machinery technology, particularly in cracker processing, and serve as a reference for the development of similar machines in the future.
