Abstract

Sugarcane (Saccharum officinarum L.) is a plant used for sugar production with waste products in the form of bagasse and sugarcane leaves. Sugarcane pulp and leaves are known t°Contain hemicellulose (xylan) which has the potential to be used as a rough substrate for xylanase-producing microorganisms. The aim of the research was to isolate xylanolytic bacteria from sugar cane plantations and to know the characteristics of xylanolytic bacteria. The research was conducted in December 2022- February 2023. This research was divided into 2 parts, namely experiment and observation. Experimental research in the form of biological characters using Completely Randomized Factorial Design (RALF). The first factor was the pH of the media, namely pH 4, pH 5, and pH 6. The second factor was temperature, using a temperature of 25°C and 45°C. Each treatment was carried out with 3 replications. To determine the characteristics of xylanolytic bacteria, an observational study was carried out by conducting a hypersensitivity test and observing the macroscopic and microscopic morphology of the bacterial colonies. The results showed that the best bacterial pH in producing the enzymatic index was at pH 4 and 25°C. Hypersensitivity test showed that all isolates were pathogenic.

Abstract

This innovative research aim to develop and test the effectives of 2D science board learning media in improving students understanding of the digestuve system and organ systems in humans, this study used the R&D ( Research and Development) method from Borg and Gall. Data collection techniques used observation, validation and testing, where the target of this study was class VII MTs/ Equivalent. The results of this study indicate that this media is interesting and interactive and effective in achieving learning objectivs, expert validation and student responses respond possitevly to atractive and interactive visual display and can improve student learning outcomes, which of course supports the conclusion that 2D science board media is a teaching and that is proven to be aeffective interactive and practical when applied to science learning Keywords: Learning Media, 2D Science Board , Research and Development, Science Learning

Abstract

This research aimed to determine the impact of the TPACK based on Project Based Learning model on biology learning outcomes and the creative thinking skills of tenth-grade students. This study was used experimental research conducted with a quantitative approach. The research employed a Quasi-Experimental design with a nonequivalent control group, comprising experimental and control groups. The research population included all tenth-grade students (phase E) of SMAN 1 LENEK for the 2024/2025 academic year. The research sample was determined using multistage random sampling. Phase E3 served as the experimental class using the TPACK based on Project Based Learning model, while phase E8 was the control class using the conventional lecture method. Data collection techniques included modified tests on learning outcomes and creative thinking skills, consisting of three essay questions. Data were analyzed using an independent sample t-test for hypotheses 1 and 2 and MANOVA for hypothesis 3. The results of this study indicated that: 1) TPACK based on Project Based Learning significantly influenced biology learning outcomes, 2) TPACK based on Project Based Learning significantly influenced students’ creative thinking skills, 3) TPACK based on Project Based Learning significantly influenced both biology learning outcomes and students’ creative thinking skills.

Abstract

This study aims to: (1) Develop a biology teaching module based on Problem Based Learning (PBL) to improve students' critical thinking. (2) To determine the feasibility and ideality of a biology teaching module based on Problem Based Learning (PBL) to improve students' critical thinking. (3) To determine the effectiveness of a teaching module based on Problem Based Learning (PBL) to improve students' critical thinking. This development research uses the Borg and Gall model which is carried out with 7 stages of development, namely: collecting initial information, planning, developing initial products, limited scale trials, product revisions, large scale trials, product revisions. The subjects of the trial in this study were material experts I and II, design material experts, 40 students of MA NW Sukamulia, and 28 SMAN 1 Lenek. Data collection techniques were carried out using questionnaires and data were analyzed using quantitative descriptive analysis techniques. Based on the results of data analysis and discussion, it can be concluded that the biology teaching module product Based on Problem Based Learning (PBL) to improve students' critical thinking skills is feasible, ideal and effective to be used during the learning process. This feasibility can be seen from the average percentage of feasibility from material expert I 93.06%, material expert II 96.99%, design expert 86.75%, and student response 79.67%. This has the criteria of very feasible and feasible. Furthermore, the ideality of the teaching module can be seen from the average score of ideality from material expert I 63, material expert II 66, design expert 68, and student response 54.05. This has the criteria of very ideal and ideal. Then the effectiveness of the teaching module can be seen from the average N-Gain obtained for the broad scale of the experimental class 0.62 and the limited scale of the control class 0.22. Based on the average N-Gain obtained, it has moderate criteria with a fairly effective level of effectiveness. Based on the results of the average percentage of the acquisition of Student Worksheets Based on Problem Based Learning (PBL) per group, it shows that Student Worksheets Based on Problem Based Learning (PBL) to improve students' critical thinking skills are in the very critical category.

Abstract

This study aims to: (1) Develop a biology teaching module with a STEAM approach based on the Engineering Design Process (EDP) to improve students’ creative thinking skills. (2) To examine the feasibility and ideality of a biology teaching module with a STEAM approach based on the Engineering Design Process (EDP) to improve students' creative thinking skills. (3) To determine the effectiveness of a biology teaching module with a STEAM approach based on the Engineering Design Process (EDP) to improve students' creative thinking skills. This development research usedthe Borg and Gall model which was carried out with 7 stages of development; initial information collection, planning, initial product development, small-scale trials, product revision, limited trials, and product revision. The subjects of the trial in this study were material experts I and II, design experts, 20 students of SMAS NWDI Tebaban, and 65 students of SMAN 1 Pringgasela. The data collection technique was carried out using a questionnaire and the data was analyzed using quantitative descriptive analysis techniques. Based on the results of data analysis and discussion, it can be concluded that the biology teaching module product with the STEAM approach based on the Engineering Design Process (EDP) to improve students' creative thinking skills is feasible, ideal and effective to be used during the learning process. This feasibility can be seen from the average percentage of feasibility from material expert I 95.14%, material expert II 93.06%, design expert 94.29%, and student response 79%. This has the criteria of very feasible and feasible. Furthermore, the ideality of the teaching module can be seen from the average score of ideality from material expert I 64, material expert II 63, design expert 81, and student response 54.05. This has the criteria of very ideal and ideal. Then the effectiveness of the teaching module can be seen from the average N-Gain obtained from the limited scale of the experimental class 0.62 and the limited scale of the control class 0.26. Based on the average N-Gain obtained, it has moderate criteria with a fairly effective level of effectiveness. Based on the results of the average percentage of the acquisition of Student Worksheets with the STEAM approach Based on Engineering Design Processes (EDP) per group, it shows that Student Worksheets with the STEAM approach Based on Engineering Design Processes (EDP) to improve students' creative thinking skills are in the very creative category.
