Quality of life can be determined by the individual's perception of his current life, including his health condition. Among occupational diseases, degenerative diseases are the first cause of death, and metabolic syndrome is one of them. This study aims to describe the quality of life of pre-elderly workers (45-56 years) with the risk of metabolic syndrome (obesity, hypertension, hypercholesterolemia and hyperglycemia) at PT. X. The research was conducted with a qualitative descriptive method. Data was collected by interview method and the results of medical check-up documents. The results showed that the respondents rated their quality of life quite well. They judged that his current physical condition was quite good. Respondents do not know that their current health condition can trigger degenerative diseases in the future if sedentary behavior is still ignored. Five of the seven respondents still do not exercise regularly and three of the seven respondents are active smokers with cigarette consumption of 3-20 cigarettes/day. The seven respondents did not pay enough attention to their food intake. Psychologically, respondents perceive their mental condition is very good, they perceive the work environment as a very comfortable place to build social relationships. More metabolic syndrome related support programs at PT X need to be offered to increase workers' awareness of their health status.

Daun cengkeh mengandung senyawa antibakteri, dan komponen utama ekstrak daun cengkeh adalah eugenol yang memiliki aktivitas antibakteri. Berdasarkan efek tersebut, penelitian ini menggunakan ekstrak daun cengkeh untuk membuat hand sanitizer alami. Penelitian ini bertujuan untuk mengukur efektivitas ekstrak daun cengkeh sebagai hand sanitizer dalam pengendalian Methicillin-resistant Staphylococcus aureus (MRSA). Metode penelitian yang digunakan adalah metode eksperimen sejati dan Rancangan Acak Lengkap (RAL), dengan 6 perlakuan dan 4 ulangan, terdiri dari kontrol dan 5 perlakuan. Uji penghambatan diuji dengan metode difusi cakram. Teknik analisis data yang digunakan adalah uji one way ANOVA 0,05 dan uji lanjutan Tukey HSD. Hasil penelitian menunjukkan bahwa hand sanitizer yang mengandung ekstrak daun cengkeh efektif menghambat pertumbuhan MRSA. Selain itu, penelitian ini menemukan bahwa konsentrasi terbaik untuk menghambat MRSA adalah konsentrasi pembersih tangan 20% dengan ekstrak daun cengkeh.

This research was conducted in order to improve the teaching material in the form of an educational CD for class VII SMP with material on physical and chemical changes (chemical reactions). The stages of research and improvement carried out include: (1) needs analysis, (2) product improvement stage, (3) feasibility study and trial stage. Analysis of the needs of class VII students of SMPN 8 Jakarta with 39 respondents was carried out with the results that 100% of respondents had used computers at relatively frequent intervals (79.92%). More than half of the respondents (66.67%) stated that the seventh grade science (chemistry) subject was quite difficult. The product improvement stage begins with a literature study to create teaching material content, and the production of teaching materials in the form of interactive CDs. Educational materials are made using Macromedia Flash interactive programming facility which includes animation of chemical reaction applications, chemical reaction processes, and practice questions with multiple choice questions. The time required for the contents of this learning CD is 15-20 minutes. The feasibility test phase carried out by material experts, media and teachers showed that the learning CDs developed were suitable for practical use. Meanwhile, small and large group experiments with class IX students of SMPN 8 Jakarta and SMP Terpadu Widya Duta Jakarta gave very good interpretation results, so it can be concluded that CD is used for learning materials on physical and chemical changes.

This study aims to determine the increase in student learning outcomes after applying the Non-Example Example learning model with the Quiziz Educational Game media to improve student learning outcomes in the seventh grade Solar System material at Maria Goretti Kabanjahe Private Junior High School. The no-example example learning model with quiziz game media is a learning strategy that uses pictures and videos as a medium to convey subject matter with the help of quiziz educational games as a medium in delivering the test instruments carried out. The subjects of this study amounted to 26 students. This non-example example method uses pretest and posttest actions in cycle I and cycle II, in order to improve student learning outcomes. Gradually in the pre-test, the average learning score was still 46.92 with a mastery percentage of 23.07%, followed by the first cycle, it was found that the student learning average was 48.46 and the percentage of completeness was 38.46%, there was a slight increase from before experiment was carried out. Then it was further improved in the second cycle, the researchers found an average learning score of 70.90 with a completeness percentage of 77.27%, it can be said that the improvement in student learning outcomes is getting better and increasing.

This study aims to improve the thinking skills of high-level students through the use of the 5E cycle learning model in class XI IPA students of SMA Negeri 2 Bagan Sinembah TP Riau 2020/2021 (PT) using the Kemmis and Mc.Taggart method to improve. The subjects of this study were 36 students of class XI IPA-1. This classroom action research was carried out in 2 cycles, with each cycle consisting of 1 session. Cycle I discusses the human excretory system, and Cycle II discusses disorders of the human excretory system. The data collection techniques used were tests of higher order thinking skills and teacher activity observation sheets in the application of the 5E cycle learning model and data analysis techniques with individual and classical percentage analysis. The results showed that the use of the 5E cycle learning model was able to improve high thinking skills (HOTS) of class XI science students at SMA Negeri Bagan Sinembah TP 2020/2021 Riau with a material removal system and increasing teacher activity in the learning process. The percentage of thinking ability (HOTS) from 50% in the first cycle increased to 67% in the second cycle in the good category, in the 85% cycle it increased to 92%, the percentage in the very good category was accepted.

The purpose of this study was to determine the increase in student motivation and learning outcomes by implementing E-LKPD based on Project Based Learning (PjBL) on the respiratory system material in humans in online learning in class VIII-B of SMP Negeri 3 Tarutung T.P. 2020/2021. The research method used is Classroom Action Research (CAR). This research was conducted in 2 cycles. The results of the student learning motivation questionnaire in the first cycle were 33.3% and the second cycle was 62.5% in the high category. Student learning outcomes in the first cycle 58.3% complete learning and 41.6% students do not complete learning. Whereas in the second cycle 87.5% completed learning and 18.5% did not complete the study. Thus it can be concluded that the application of PjBL-based E-LKPD on respiratory system materials in humans in online learning in class VIII-B SMP Negeri 3 Tarutung T.P. 2020/2021 can increase student motivation and learning outcomes
本研究的目的是通过实施基于项目学习(PjBL)的E-LKPD，在SMP Negeri 3 Tarutung T.P. 2020/2021年VIII-B班在线学习中人类呼吸系统材料，来确定学生动机和学习成果的增加。研究方法为课堂行动研究(CAR)。本研究分2个周期进行。第一周期学生学习动机问卷得分为33.3%，第二周期学生学习动机问卷得分为62.5%，得分较高。第一个周期学生的学习成果58.3%的学生完成了学习，41.6%的学生没有完成学习。而在第二个周期中，87.5%的人完成了学习，18.5%的人没有完成学习。综上所述，基于pjbl的人类呼吸系统材料E-LKPD应用于VIII-B级SMP Negeri 3 Tarutung T.P. 2020/2021的在线学习中可以提高学生的学习动机和学习效果
