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.

Abstract

This study aims are (1) evaluate the implementation of the UKK of the LSP-P1 certification scheme in Vocational High Schools, (2) determine the involvement of industry in the UKK implementation process, (3) determine the impact of collaboration between Vocational High Schools and industry in the implementation of UKK on increasing the employability of TVET graduates, so that strategic recommendations are generated for Vocational High Schools, LSP-P1, and industry in increasing the effectiveness of UKK implementation and increasing the employability of TVET graduates. This study uses an evaluation research method using the CIPP model, a descriptive evaluative approach that incorporates survey techniques and in-depth interviews. Respondents include the head of the expertise program, the head of the TUK, LSP-P1 assessors, representatives of partner industries, and alumni who have participated in the UKK. Data are analyzed quantitatively and qualitatively. This study was conducted in West Java at six TBSM Vocational High Schools. The results show that the LSP-P1 UKK is relevant to the needs of the automotive industry, but is not fully adaptive to the development of EV technology. Assessors and test materials are quite appropriate, but modern facilities and competency updates are still obstacles. The implementation process meets standards, but external oversight from the industry needs to be strengthened. Certified graduates have higher employability than non-certified graduates, but their readiness for new technologies remains limited. Therefore, the UKK (LSP-P1) certification scheme has proven effective in increasing the competitiveness of TBSM vocational high school graduates in West Java. However, it requires curriculum innovation, strengthening of facilities, and more intensive involvement from industry at every stage of implementation, including assessor criteria, competency test materials, assessment standards, and recognition of competency certificates.
