This research addresses the low student learning outcomes and the lack of facilitation of 4C competencies (Critical Thinking, Collaboration, Communication, and Creativity) in the Industrial Machine Electrical Systems (SKMI) subject for Grade XI TMI 1 students at SMK Negeri 1 Pariaman. The teacher-centered learning approach has led to passive student participation, low critical thinking, varying academic abilities, and difficulty in connecting theoretical concepts to real-life applications. The aim of this study is to improve students' 4C competencies and learning outcomes through the implementation of the Team Assisted Individualization (TAI) cooperative learning model. Using Classroom Action Research (CAR) based on the Kemmis and McTaggart model, the study was conducted in three cycles: planning, implementation, observation, and reflection. The subjects were 30 students from Grade XI TMI 1. Data collection included learning outcome tests and 4C competency observation sheets, with descriptive and quantitative data analysis. The results showed significant improvements: classical mastery increased from 27% to 90%, average learning scores rose from 67 to 81, and 4C competency mastery improved from 34% (low) to 82% (high). The study concludes that the TAI model effectively enhances both 4C competencies and learning outcomes in SKMI at SMK Negeri 1 Pariaman.

Vocational high schools (SMK) play an important role in preparing students for the world of work. However, student learning outcomes in the subject of Electrical Lighting Installation at SMK Negeri 5 Kota Padang are still relatively low, with an average pretest score of 57.34. This study aims to test the effectiveness of the Student Teams Achievement Division (STAD) cooperative learning model in improving student learning outcomes. The research method used was classroom action research with 32 students from class XI TITL as subjects. Data were collected through pre-tests, post-tests, and observations of student activities during learning. The results of the study indicate that the implementation of STAD successfully improved student learning outcomes significantly, with an average post-test score of 82.19 and an N-Gain Score of 0.58 (moderate category). Academic achievement also increased from 15.6% to 75%. Further analysis revealed that collaborative interactions within groups, the reward system, and active student participation were key factors contributing to the success of this method. However, challenges such as time management and low student engagement require attention. It is concluded that the STAD model is effective in improving students' learning outcomes in the subject of Electrical Lighting Installation, both in terms of cognitive aspects and social skills. Therefore, it is recommended that teachers implement STAD with proper syntax and consider developing supporting media such as digital simulations to optimize the learning process.

During the field work practice, the author observed that there were obstacles in placing pedis examinations on non-cooperative patients so that the examination was not optimal. This obstacle resulted in radiologists not being able to carry out their expertise properly. In addition, if the referring doctor asks for a repeat photo, it will give the patient an excessive radiation dose. With such patient conditions, a fixation device is needed so that the examination produced optimal results. Innovation efforts are needed to overcome this in order to improve services and prioritize patient safety. In addition, according to Lampignano & Kendrick, (2018), it is not permissible to force injured limbs or body parts into a certain position, the position must be adjusted according to needs. So that patients with multiple fractures require special treatment that is different from patients in general. The researcher designed a fixation device that can be used in the patient's supine and sitting positions without having to lift the patient's thigh, genu, and cruris bones and also without looking at the size of the patient's feet.

Structured and efficient inventory management is very important for cooperatives, which have special operational and logistical needs. This study aims to develop a web-based inventory system and also develop it into a mobile application that is able to support real-time stock and asset management, using Javascript, PHP, HTML, CSS, and implemented on the XAMPP platform with phpMyAdmin support. This system is designed to record and monitor goods accurately, optimize the flow of goods in and out, and provide automatic inventory reports. The waterfall approach is applied in the development of this system, starting from needs analysis, design, implementation, to testing. The results of the study show that this system has succeeded in increasing the accuracy of recording goods, accelerating the decision-making process through data-based reports, and reducing manual errors that often occur in inventory management. This system not only supports operational transparency, but also helps a cooperative in achieving logistical efficiency and resource optimization.

This study aimed to know the prediction of rice sales for Employee Cooperatives Republic of Indonesia Bina Warga Benjeng in the following month. Rice sales are often difficult to predict market demand. When consumer demand increases, rice supplies sometimes suffer from shortages. If consumer demand decreases, stock builds too much and results in a decrease in rice quality. In order for the rice sales process to run smoothly, it is necessary to have a sales prediction so that there are no excesses or shortage in rice supplies. The method of discussion used to predict in this study using the Single Moving Average method which is a prediction method that uses new actual data requests to raise the predictive value of the next month’s demand. The best results were using the Single Moving Average methods using rice sales data variant 25 kg variant were successfully implemented with an RMSE value of 9.3% which means this prediction accuracy of 90.7% accurate.
