Abstract

Sauerkraut is a typical German food made from thinly sliced cabbage. Sauerkraut is a fermeted product that can give a distinctive taste. Sugar is an ingredient that can be added in, that sugar can trigger the growth of lactic acid bacteria. Indonesian people like food with a spicy sensation from chilies, chillies here contain vitamin C which functions as an antioxidant that is good for the body and is able to increase endurance. This study aims to calculate the total lactic acid bacteria contained in sauerkraut with the addition of chilies and sugar. Dilution of 1 ml sample into 9 ml physiological NaCl solution from 10 -1 to 10 -8 dilutions was carried out, then inoculated into MRS Agar using the pour plate method. Incubated in room temperature for 48 hours. The growing colonies of lactic acid bacteria were then observed based on colony morphology and counting the total growing lactic acid bacteria. The results of the research can be concluded that there was an increase in the number of lactic acid bacteria in sauerkraut with the addition of chili and 10% granulated sugar with a bacterial density average is 88.667 x 108 CFU/mL.

Abstract

The current state of science learning in madrasah reveals a lack of integration between teaching materials and technology, as well as a failure to incorporate relevant al-Qur'an verses connecting propositions to scientific content. Moreover, the absence of assessments evaluating students' motivating attitudes toward learning further compounds these challenges. This study seeks to assess the necessity of developing integrated teaching materials for science education in Temanggung Regency's madrasah, employing flip books as a technological tool. Participants included six science teachers and nine students, and data was collected through interviews. Analysis involved data reduction, presentation, and conclusion. The findings indicate a shared need among teachers and students for teaching materials that seamlessly blend technology and al-Qur'an verses through flipbooks in science education. Consequently, future research should focus on the development of flipbooks that incorporate al-Qur'an verses as integral components of teaching materials for enhanced science learning experiences.

Abstract

This study aimed to ascertain how well the problem-based learning model and physics education technology (PhET) simulation improved student learning outcomes in acid-base materials. The research method used was a quasi-experiment with a non-equivalent control group design. Data collection techniques were used in this study by providing test instruments in the form of multiple-choice questions, pretests and posttests, and observation sheets of teacher and student activities. The findings revealed that students taught using the PBL model with PhET simulation achieved an average learning outcome score of 79.29, while those taught using the PBL model alone obtained an average score of 73.97. The calculated average N-gain of 0.70 (categorized as medium) indicates that the PBL model with PhET simulation significantly contributed to enhancing student learning outcomes. This study demonstrates that integrating the PBL model with PhET simulation is an effective approach for improving student learning outcomes in the context of acid-base materials. The results highlight the importance of experiential, inquiry-based approaches combined with technology in enhancing student engagement and understanding. Further research could explore the long-term effects of implementing this instructional approach and investigate its impact on broader aspects of student learning in science education.

Abstract

This research aims to describe teachers' understanding of Culturally Responsive Teaching (CRT), difficulties to implement it, and its relation to higher order thinking skills through descriptive qualitative method using interview instrument. The research subjects were twenty science teachers from three senior high schools that have implemented Independent Learning Curriculum in Medan City and Deli Serdang Regency in North Sumatera. The results revealed that 70% of teachers have limited understanding and only 30% of the teachers who understand the concept of this learning correctly. The research results also showed that only 20% had ever implemented CRT in their classrooms and 80% had never implemented. This is all due to difficulties. Based on previous research, it shows that CRT make many positive contributions to learning processes and outcomes, improving the learning process and outcomes, improving higher order thinking skills and building student’s character. Therefore, teachers need to understand, be able to design and implement learning model based on CRT to serve diverse students.

Abstract

Learning media is an intermediary in the learning process, and is expected to arouse student motivation in learning activities, especially in physics lessons. However, some teachers have difficulty adapting the media to the material that will be provided, especially global warming material. So that causes a lack of interest in learning students to read textbooks, which results in a low understanding of students' concepts of physics subjects, especially on global warming material. The purpose of this study was to determine the increase in learning motivation and understanding of students' concepts through the use of problem solving-based physics comics on global warming material. The method used in this study is qualitative, a type of quasi-experimental research (quasi-experiment). The research design used was a two-group pretest-posttest design. Totaling 30 students selected by cluster random sampling. The instruments used in this study were test instruments (pretest-posttest) and non-test instruments (questionnaires). Data analysis shows the value of Sig. < 0.05, namely 0.00, thus Ho is rejected and Ha is accepted. It can be concluded that the use of problem solving-based physics comic media on global warming material can improve students' understanding of concepts.

Abstract

Clean and healthy living behavior in schools is an effort to empower students, teachers and the school community to know, want, and be able to practice PHBS and play an active role in creating a healthy school. PHBS must be instilled from an early age so that it can be carried over into adulthood. Elementary school children are still relatively young, so they need help from people in their immediate environment, namely parents, teachers and friends. The research aims to determine the influence of peer tutors' health promotion on clean and healthy living behavior (PHBS) in schools. This research uses bivariate analysis to determine the influence of peer tutor health promotion on clean and healthy living behavior (PHBS) in schools using a dichotomous quantitative comparative test with Mc Nemar Test analysis. The results of this research were that the number of students who experienced a change in PHBS behavior from "Not Good" to "Good" was 33 (91.7%) people and no students experienced a change in PHBS behavior from "Good" to "Not Good". Furthermore, of all the students in the sample there were 3 (8.3%) students whose PHBS behavior did not change or remained "Good" behavior.

Abstract

This research aims to describe and explain simultaneously whether there are differences in science learning motivation and critical thinking skills of students who learn using different learning models. The experimental class is with modified POE, while the control class is with a conventional learning model. This type of research is a quasi-experimental research design with a nonequivalent pretest-posttest control group design. The data obtained were analyzed descriptively and the hypothesis was tested using MANCOVA. The research results showed that simultaneously there were significant differences in science learning motivation and students' critical thinking skills between the experimental and control classes in terms of the results of the analysis of the students' achievements. The modified POE learning model is better at increasing students' science learning motivation and thinking skills compared to 5M learning.

Abstract

This research was conducted in the experimental garden of the Faculty of Agriculture, Klabat University, from August to December 2018. The research aimed to determine the response to the growth and production of sweet corn due to the application of NPK Mutiara fertilizer and to obtain the correct dose of NPK Mutiara fertilizer for the growth and production of sweet corn. This research used a Randomized Block Design (RAK) with four levels of treatment, namely T0 (without Mutiara NPK fertilizer treatment) as a control, T1 (2 gr/plant), T2 (4 gr/plant), and T3 (6 gr/plant) where each treatment was repeated four times. The research results were that the dose of Mutiara NPK fertilizer did not influence plant height and number of leaves because the growth response of sweet corn was not large enough to have a real influence on plant height and number of sweet corn leaves. The Mutiara NPK dosage influences the flowering age and cob weight because the response of the sweet corn plants is large. The dose of Mutiara NPK fertilizer does not affect plant height and number of leaves but does affect flowering time and ear weight. The best dose of Mutiara NPK fertilizer is 6 gr/plant.
