Abstract

Pembuatan keputusan yang efektif harus didukung oleh integrasi data, otomatisasi pembuatan model simulasi dan visualisasi dari hasil yang interaktif. Sehingga diperlukan Sistem Pendukung Keputusan (SPK) untuk meningkatkan efektivitas penjadwalan operasi mesin perusahaan, mengetahui line yang perlu overtime dan membuat action plan perbaikan untuk line yang tidak mencapai plan good quantity production. Macro VB excel dapat mempercepat proses query data, fishbone dan FMEA untuk root cause analysis. Hasil penggunaan SPK didapat peningkatan efektivitas menjadi 3.5 jam lebih awal dalam pembuatan analisa data dan perlu overtime sebanyak 7,4 shift untuk mengejar ketertinggalan plan good sebesar 20.593 pcs. Hasil production meeting dengan metode FMEA, perlu adanya empat action plan diantaranya dibuatkan SOP untuk meminimalisasi frekuensi dan lama adjustment mesin, setting overtime rutin di harian operasi, dibuatkan perbedaan pengaturan operasi jika menggunakan wheel hasil reproduksi supplier, dibuatkan parameter baku untuk tiap jenis proses dan cycle time parameternya.

Abstract

Friction Stir Welding (FSW) is a solid-state bonding process that employes tools that are not used up and can function to connect two opposite workpieces without melting the workpiece material. The friction force has been micro-structurally tested to reformat or transform the inner state of the structure properties (atomic formation) form in metal since the kinetic energy of friction has been utilised in one of the welding techniques. Right afterwards, the studies reported that the mechanical properties also underwent a significant deformation. The aim is to determine the effect of Welding Procedure Specification (WPS) product quality. As it develops through research and applied experiments, the branch of friction-based welding discipline can be classified depending on how the friction mechanism can produce the finest solid-state joint, which is suitable to the typical property of metal and can be maximised by joint configuration. Friction Stir Welding is a friction-based welding technique that uses the stirring tool to generate friction while the workpieces are stuck on the line of the FSW joint configuration. The relevant correlations amongst process parameters and inside its respective adjustable variables are constructed to the finest principles that produced top-grades empirical reports of the weld properties. In this review, the explanation of the working principle and clarification of process parameters are presented. The cited references are selected from creditable and verifiable articles and books in the last ten years. Expectedly, it will be able to pioneer a new face of simple and understandable review articles.

Abstract

Project-based learning is considered important for developing student character because it provides students with the opportunity to learn through experience (experiential learning). The Project-based Learning (PjBL) model is a learning model that involves students' activeness in solving problems, carried out in groups/independently through scientific stages with certain time limits which are outlined in a product to then be presented to others. Starting from 2022 to 2024, the Ministry of Education, Culture, Research and Technology (Kemendikbudristek) provides three curriculum options that can be applied by educational units in learning, namely the 2013 curriculum, emergency curriculum and prototype curriculum. The prototype curriculum has been implemented in 2,500 educational units that are members of the Driving Schools and Center of Excellence Vocational Schools program in 2021. However, starting in 2022, educational units that are not included in driving schools will also be given the option to be able to implement the prototype curriculum. The capstone project is a culmination of the learning process by applying what has been learned in the learning process. Innovation and product development is something that companies rely on to be able to progress and compete in the industrial world. Industrial products will ultimately be produced in a manufacturing system where everything becomes more complex. Insight and knowledge regarding capstone design projects through training to introduce the stages of the product and system development process. Community Service activities have been carried out with vocational school student participants showing enthusiasm and increased knowledge regarding the capstone design project.

Abstract

In the era of globalization and digitalization, sustainable entrepreneurship is one of the key factors in encouraging inclusive and environmentally friendly economic growth. Effective resource management is a major challenge for business actors, especially in ensuring business competitiveness amidst increasingly fierce competition. Along with technological developments, resource management strategies have also undergone significant transformation. Initially, resource management strategies emphasized operational efficiency and cost savings. However, as awareness of the importance of sustainability increases, this approach has developed into a more holistic strategy that takes into account economic, social and environmental aspects. Indonesian Migrant Workers (TKI) in Penang, Malaysia have a great potential to develop sustainable entrepreneurship. However, many TKI still face difficulties in managing resources effectively, which hinders their entrepreneurship competitiveness. With the advancement of technology and globalization, effective resource management has become crucial to enhance sustainable entrepreneurship competitiveness.

Abstract

This study investigates the effects of Dual-Tool Friction Stir Welding (DT-FSW) parameters on the weld quality of 8 mm thick 6061 aluminum alloy plates, specifically focusing on the elimination or minimization of the "pass-overlap zone" that’s a gap typically observed at the mid-section of the weld cross-section resembling characteristics of the Heat-Affected Zone (HAZ). To address ongoing debates regarding the optimal joint performance concerning this overlap, symmetric increases in the dimensions of both FSW tools were implemented to analyze resultant temperature fields and plastic strain adaptations at the weld interfaces. Simulation visualizations were conducted with tool density variations at intervals of 0.2 mm and 0.4 mm. Results indicate that increasing tool density, thereby reducing the distance between tool surfaces, leads to a decrease in peak temperatures generated during welding. This reduction in temperature correlates with a more uniform distribution of plastic strain rates across all layers of the material—upper, middle, and lower—with the leading edge exhibiting the most significant improvement in strain uniformity. Conversely, during the stabilization phase, a decrease in tool density (S) results in a reduction of the maximum equivalent plastic strain rate. These findings suggest that careful adjustment of tool density in DT-FSW processes can enhance weld quality by promoting more uniform mechanical and thermal properties across the joint.

Abstract

Robotics is a field that combines engineering, electronics, and programming to design and control robots. In the introductory robotics program at SMK 10 Nopember Jakarta, students will learn the basics of robotics, including the main components of robots, how automated systems work, and programming to operate robots. Forty-four students attended. The goal of this activity was to increase students' understanding of robotics technology, encourage creativity in technological innovation, and provide practical skills applicable to the automation and technology industries. With project-based learning, students will have the opportunity to design and build a simple robot. Students successfully built the robot, but some were unable to due to time constraints, so we provided video tutorials for them to work on outside of school hours.

Abstract

This community service program introduces in-line robotic technology to vocational high school students in the Office Management major, focusing on administrative automation within a green supply chain framework. Using an educational, participatory approach, the program includes theoretical material, case studies, hands-on robot assembly, and reflective discussions. Results show that students grasped basic robotic concepts, automation workflows, and their relevance in supporting efficiency and reducing administrative waste. This technology-based learning promotes students' competency in adapting to digital office environments and modern workplaces. Questionnaire-based evaluation revealed that improvements are needed to better align the theme with student interests and to optimize supporting facilities.
