Abstract

Many factors determine the product quality, such as surface roughness and cutting width, especially in plate cutting industry. Getting the minimum roughness and the suitable cutting width becomes much easier if the machine operators know the right parameter while cutting. In this study, plasma cutting is used. Some parameter in this study are considered such as cutting speed, cutting height, arc voltage and air flow rates on cutting aluminium 5083 with 10 mm thickness. The analysis is conducted using Taguchi Grey Relational Analysis Method to surface roughness and cutting width. The result from this study is getting the optimal parameter combination consists of cutting speed with 1470 mm/min, cut height with 6 mm, arc voltage with 163 volt and air flow rates with 40 lpm. Moreover, the percentage contribution for cutting height is 6,780%, arc voltage is 20,141% and air flow is 56,779%. Meanwhile cutting speed didn’t signi ically a ect sur ace roughness and cutting width.

Abstract

National education aims to develop the potential of students to become individuals who are faithful, devout, have noble character, knowledge and creativity. In this digital era, teachers are required to be innovative, especially in utilizing learning media such as e-modules. At SMP Negeri 6 Sukabumi City, it was found that students had difficulty learning football material and needed additional interactive learning resources, such as flipbook-based e-modules. This research aims to develop, test the validity and measure the practicality of a soccer e-module, as well as observe its impact on student learning motivation. The method used is Research and Development (R&D) with the ADDIE model, which includes the Analyze, Design, Develop, Implement and Evaluate stages. The research was conducted at SMP Negeri 6 Sukabumi City involving 35 class IX students. Data was collected through observation, interviews, questionnaires and documentation. The research results show that the football e-module developed has been assessed as very valid with a percentage of 85% from material experts, 85% from learning experts, and 82.5% from media experts. This e-module is also practical to use in learning, with an increase in practicality from 71% in the first meeting to 80% in the second meeting. This flipbook e-module has proven to be effective in supporting PJOK learning, especially regarding soccer material.

Abstract

The aim of this research is to determine whether there is a relationship between arm muscle strength, arm length and hand-eye coordination on the results of volleyball serves in extracurricular students at Fatahillah Middle School, Sukabumi City, academic year 2023/2024. The development of science and innovation, sports in Indonesia, especially volleyball, is progressing very rapidly. Therefore, in this game you are required to have a tall physique, strong muscles and reliable movement coordination in carrying out all the movements in the volleyball game with sports development as part of efforts to improve spiritual and physical health. The method used is a survey method with tests and measurements. The sampling technique was a total sampling of 17 students. The research instrument uses an Anthropometer as a tool to measure arm length. The data analysis technique used is standard deviation, looking for normality and homogeneity values ​​and then looking for paired T test values. The results of this research are that there is a significant effect, with the paired sample t test, muscle strength and eye-eye coordination obtained a significance value of 0.000. relationship between arm muscle strength, arm length and hand-eye coordination on volleyball service results among extracurricular students at Fatahillah Middle School, Sukabumi City.

Due to the diverse educational backgrounds and digital skills of students in both undergraduate and graduate programs at Universitas Terbuka, there is a need to optimize the institution's e-learning program. This study aims to find out the concept of the implementation of e-learning strategies for the students of Universitas Terbuka and the evaluation process of the e-learning conducted in the distance learning mode. This research used descriptive qualitative research, employing two research instruments: semi-structured interviews and document analysis. Ten graduate students who have two years’ experience with the Universitas Terbuka e-learning activities were invited in the semi-structure interviews. Data analysis follows the interactive analysis model and SWOT Analysis. These stages collectively yield strategies for implementing e-learning learning and the evaluation of e-learning learning. The results of this study show that the e-learning implemented in Universitas Terbuka has greatly helped the students to follow the UT learning process effectively and has greatly improved the overall e-learning experience for the students. The findings from this research also show that diverse learning resources are able to cater the various learning styles and preferences, as well as enhancing student engagement and understanding. Some recommendations in relation to the implementation of e-learning are provided.

Abstract

This study aims to explore the effectiveness of the Directed Reading Thinking Activity (DRTA) strategy in enhancing students' reading motivation and learning outcomes. Conducted using a mixed-methods approach, it involved 27 ninth-grade students at the Al-Gazali Islamic Boarding School. The study meticulously examines how the DRTA strategy, which encourages students to make predictions, pose questions, and enhance their comprehension through engaged reading, impacts their motivation to read and their levels of reading comprehension. By integrating both quantitative and qualitative research methods, this study provides a comprehensive analysis of students' reading performance before and after the implementation of the DRTA strategy. The findings indicate a significant improvement in students' reading motivation and overall reading achievement. This suggests the potential of the DRTA strategy as an effective pedagogical tool for comprehensive reading enhancement. This research offers insights into reading strategies that can foster a more engaging and productive reading environment for students, including those in Islamic boarding school settings.

Abstract

This study aims to explore the process of religious maturation within the Majlis Ta’lim Al-Muhibbien, located in Kampung Elo, Sukamanah Village, Sukatani District. This institution functions not only as a center for Islamic religious education but also as a form of social rehabilitation for individuals who have experienced drug addiction. Through in-depth interviews and observations of the majlis caretaker, Ustadz Abdul Kholik, as well as interactions with the students, the study finds that the process of religious maturity is cultivated through the strengthening of Islamic creed (aqidah), exemplary conduct, interreligious tolerance, and special mentoring for students from diverse social backgrounds.
