Abstract

This activity aims to improve workshop management and technician competence in the dynamo maintenance field by designing an innovative tool in the form of a linear actuator-based bearing removal puller. Dynamo workshops often face challenges in the bearing removal process, which is time-consuming, requires a lot of energy, and is prone to causing damage to dynamo components. Therefore, to overcome these problems, an automatic bearing removal tool using linear actuator technology was developed. This tool is expected to increase the work efficiency of technicians by speeding up the bearing removal process, reducing the risk of component damage, and increasing work safety. This activity has three stages: preparation, implementation, and evaluation in its development using an experimental approach and training skills, where tools designed based on the needs of industrial partners Kalimasada at Sukoharjo Regency were tested and continued with training on the use of tools and providing reinforcement on workshop management. The results show that using a linear actuator-based bearing release puller can reduce the release time faster to increase technician confidence in performing dynamo maintenance. Thus, this innovation significantly improves dynamo workshop operational management and technician competence.

Abstract

One of the problems faced in the world of education is the problem of learning that needs to involve students in the learning process. Teachers still need to implement the use of learning models fully, so the learning process is only teacher-centered, and learning does not involve active students. This research was conducted to determine the effect of applying the discovery learning model on students' learning outcomes on the protists concept using the quasi-experimental method. The results showed that the students' learning outcomes on the protists concept in the experimental class after applying the discovery learning model on the protists concept (= 43.2) is better than the control class (= 40.6). In can be concluded that the there is an effect of applying the discovery learning model on students' achievement on the protists concept.

Abstract

Matrix structure is a fundamental concept in linear algebra that plays a crucial role in modern computing systems. Matrices are used as structured data representations in various applications such as digital image processing, artificial intelligence, control systems, and computer graphics. This study aims to comprehensively analyze the concept of matrix structure and its implementation in computing systems. The method used is a literature study with a descriptive-analytical approach to various scientific sources. The results of the study indicate that the matrix approach can improve computational efficiency, simplify complex system modeling, and support parallel computing on modern hardware such as GPUs. Furthermore, matrices also play a role in algorithm optimization and numerical solutions. However, the use of matrices on a large scale has limitations such as high memory requirements and increased computational complexity. Therefore, the development of more efficient optimization methods and computational techniques is needed to maximize the use of matrices in modern computing systems.
