PENGEMBANGAN MODUL KIMIA SOCIO-SCIENTIFIC ISSUES (SSI) MATERI REAKSI REDUKSI OKSIDASI Sofiana, Sofiana; Wibowo, Teguh
JEC: Journal of Educational Chemistry Vol 1, No 2 (2019)
Publisher : Chemistry Education Department

Penelitian pengembangan ini dilatarbelakangi oleh kesulitan belajar pada materi reaksi reduksi oksidasi yang dialami peserta didik akibat terbatasnya jumlah bahan ajar yang dapat digunakan secara mandiri, kurangnya variasi bahan ajar yang digunakan guru, dan rendahnya motivasi belajar peserta didik karena menganggap mata pelajaran kimia adalah mata pelajaran yang sulit, dan tidak berkaitan langsung dengan kehidupan, khususnya materi reaksi reduksi oksidasi. Hal ini ditunjukkan oleh adanya 58,9% peserta didik yang menyatakan materi reaksi reduksi oksidasi adalah materi yang sulit. Bahan ajar yang memberikan kesempatan bagi peserta didik untuk belajar menurut kecepatan masing-masing adalah modul. Tujuan penelitian ini adalah untuk menghasilkan modul yang memuat pembelajaran kontekstual dengan pendekatan socio-scientific issues (SSI). Model pengembangan yang digunakan dalam penelitian ini adalah model pengembangan ADDIE (Analyze, Design, Develop, Implement, Evaluate). Subjek penelitian pengembangan ini adalah 9 peserta didik kelas X MIA 2 MA Al-Irsyad Gajah. Hasil penilaian kualitas modul yang dilakukan oleh validator ahli materi diperoleh sebesar 84,60% dengan kategori sangat valid. Penilaian validator ahli media sebesar 91,00% dengan kategori sangat valid, dan respon peserta didik sebesar 80,69%. Sedangkan rata-rata skor untuk uji keterbacaan modul sebesar 68,88% dengan kategori keterbacaan tinggi. Hasil tersebut menunjukkan bahwa modul yang dikembangkan layak digunakan dan diimplementasikan pada kelas besar.

This research focuses on the description of bullying cases that occur among students of SMK Kesehatan Triple J Citeureup, West Java. Bullying is an aggressive action that is unwanted by the victim, either an individual or a group. This action is carried out with the aim of hurting the victim, both physically and emotionally. Bullying recurs or has the potential to recur in the future. The research method used was descriptive quantitative using the Olweus Bully/Victim Questionnaire (OBVQ) to measure three types of bullying, namely verbal, physical, and non-verbal/non-physical. The research sample consisted of 88 students selected by total sampling. The study showed verbal bullying was the most frequent form of bullying, with 43.2% of students reporting never experiencing verbal bullying, 42% experiencing bullying once or twice a month, and 14.8% experiencing bullying one or more times a week. Physical bullying was reported by 69.3% of students who never experienced it, 22.7% experienced physical bullying once or twice a month, and 8% experienced physical bullying one or more times a week. Meanwhile, non-verbal/non-physical bullying was reported by 53.4% of students who had never experienced it, 28.4% experienced bullying once or twice a month, and 18.2% experienced bullying one or more times a week. This shows that bullying is still a serious problem in the school environment, especially verbal bullying. This study calls for a comprehensive intervention program to reduce bullying, including education on the impact of bullying, psychological support for victims, and the development of social skills among students. In addition, it is important for schools to develop clear anti-bullying policies and involve all parties, including teachers, parents, and students, in an effort to create a safe and inclusive school environment.

Forensic science plays an important role in Disaster Victim Identification (DVI), especially when primary identification methods such as fingerprint analysis, forensic odontology, and DNA profiling cannot be performed. In disaster victims whose body parts are dismembered, the parts need to be reassembled. One body part that is commonly separated is the foot, which is often protected in footwear such as shoes. By predicting height using foot length measurements, it is expected that forensic officers can reassemble the separated body parts based on the predicted height calculation. This study examines the correlation between foot length and height to establish a reliable regression formula for height estimation. Data were analyzed using SPSS 26 with normality tests, correlation analysis, and linear regression. The study results showed a statistically significant positive correlation between foot length and height (Pearson correlation: 0.821– 0.844), confirming that foot length is a strong predictor of height. The regression model (Height = 61.652 + 0.429 × Foot Length) explains 83.9% of the height variation, making it a valuable tool in forensic anthropology. This method can assist in victim identification, especially in mass disasters, dismemberment murder cases, and other forensic cases. Further research with larger and more diverse samples, including gender-specific models, is recommended to improve the accuracy and application of this regression formula.

The Ministry of Health stated that non-communicable diseases cause high mortality rates each year and can infect individuals of all ages and countries around the world. Non-communicable diseases include heart disease, diabetes mellitus and kidney disease. To overcome these health problems, preventive measures are needed that aim to improve the quality of life of the nation. This is stated in the Presidential Instruction which is one part of the meaning of Germas, namely routine health checks that are useful for facilitating early detection of diseases or health problems. The examinations carried out are divided into 2, namely examination of random blood sugar levels, uric acid, and cholesterol levels and EKG (Electrocardiography) examinations. The purpose of community service is to provide information on the results of examinations of random blood sugar levels, uric acid, and cholesterol levels by the PkM TEAM from Lecturers together with Cadets of the Indonesian Defense University for the people of Muare Angke in improving health. The method is by examining random blood sugar levels, uric acid and cholesterol. The results concluded that most respondents had normal blood sugar levels, uric acid levels, and cholesterol levels.

This study aims to examine the effectiveness of the Differential Reinforcement of Low Rates (DRL) technique in reducing tardiness behavior among ninth-grade students at SMP Negeri 61 Surabaya. Student tardiness is considered not only a matter of discipline violation but also a factor that disrupts classroom effectiveness; thus, a classroom management strategy grounded in Skinner’s behaviorism is required. The research employed a quantitative approach with a Single Subject Research (SSR) A-B-A design. Five students with consistently high levels of tardiness were purposively selected as research subjects. Data were collected through attendance records across three phases: baseline one (A1), intervention (B), and baseline two (A2). The intervention involved providing positive reinforcement such as verbal praise, reward points, and special privileges whenever students arrived on time. Data were analyzed descriptively using frequency counts of tardiness per week and visualized through graphs to identify behavioral trends. The results revealed a significant decrease in tardiness frequency from the baseline to the intervention phase, with stability maintained during the second baseline. These findings confirm that DRL is a simple, effective, and contextually relevant strategy for fostering student punctuality and discipline. The novelty of this study lies in applying differential reinforcement in a public junior high school setting with limited resources, contributing fresh insights into the Indonesian context of classroom management.
