The bacteria Staphylococcus aureus, a normal component of human flora, is easily mutated and antibiotic-resistant, leading to the creation of Methicillin-Resistant Staphylococcus aureus (MRSA). This bacterium is a difficult-to-control nosocomial infection in healthcare settings, so it must be stored using specialized preservation agents, like DMSO, to investigate the nature and characteristics of these bacteria for prevention, control, and therapy. The purpose of this study was to evaluate the survival of MRSA bacteria that had been kept in a DMSO solution at various temperatures and periods. This study was carried out between July and October2022 using a one-shot study case research design, data analysis, and quantitative descriptive analysis. According to the findings, MRSA bacteria held in 15% DMSO solution lost viability over time and at various storage temperatures. Among various bacterial species held at various storage temperatures, MRSA bacteria had the lowest colony loss rate (-20 °C). Based on the findings of this study, it can be said that the preservation of MRSA bacteria at freezing temperature (-20 °C) and storage length of one month resulted in the greatest survivability of the bacteria when stored in 15% DMSO solution.

Practicum worksheets are a tool used by students to increase their understanding of various biological concepts through experiments and direct observation. However, there are many biology practicum worksheets used today often do not meet the appropriate standards. Therefore, this research aims to analyze conceptual, procedural, and knowledge construction aspects based on vee diagrams on students' practicum worksheets. The method used in this research is qualitative-descriptive. The samples were selected using purposive sampling so that six samples of practicum worksheets for phase F students in the Merdeka Curriculum were obtained with material testing carbohydrates in food. The research results show that conceptually, the practicum content is not in accordance with the learning outcomes in the Merdeka Curriculum. Procedurally, the practicum worksheets still need to be improved in terms of tools, materials, procedures, phenomenon objects, and data recording. This has an impact on students' difficulties in constructing their knowledge. It is hoped that the results of the reconstruction of practicum worksheets based on conceptual, procedural, and knowledge construction analysis can be used as a reference and basis for teachers in designing practicum activities specifically on digestive system material.
实习作业单是学生通过实验和直接观察加深对各种生物概念理解的一种工具。然而，目前使用的许多生物实习作业纸往往不符合相应的标准。因此，本研究旨在根据学生实习作业纸上的维氏图，从概念、程序和知识建构等方面进行分析。本研究采用定性描述法。样本的选取采用了目的取样法，因此获得了六份默迪卡课程 F 阶段学生的实习作业纸样本，其中有测试食物中碳水化合物的材料。研究结果表明，从概念上看，实践内容与默迪卡课程的学习成果不符。从程序上看，实践作业单在工具、材料、程序、现象对象和数据记录方面仍需改进。这对学生构建知识的困难造成了影响。希望基于概念、程序和知识建构分析的实践作业单重建结果，能为教师设计专门针对消化系统材料的实践活动提供参考和依据。

In addressing environmental issues, it is important to measure STEM literacy achievement to increase students' environmental awareness and equip them with the necessary skills to contribute to finding solutions. This research aims to determine the profile of students' STEM literacy achievement in Bandung regarding environmental change issues. The research method used is descriptive with a qualitative approach. The research subjects comprised 193 tenth-grade students selected from SMA Negeri 1 Bandung, SMA Negeri 4 Bandung, and SMA Negeri 9 Bandung for the 2023/2024 academic year, chosen through simple random sampling. The research instrument consisted of 40 multiple-choice questions on environmental change issues, covering seven STEM literacy indicators: explaining phenomena scientifically, evaluating and designing scientific investigations, interpreting data and evidence scientifically, understanding technological principles, developing solutions to achieve goals, formulating situations mathematically, and using concepts, facts, procedures, or reasoning. Data analysis was conducted by calculating the average score of students' STEM literacy achievement per indicator as a percentage. The research results indicate that the percentage of students' STEM literacy achievement is 70%, categorized as moderate. The percentages per STEM literacy indicator are as follows: explaining phenomena scientifically at 71%, evaluating and designing scientific investigations at 61%, interpreting data and evidence scientifically at 73%, understanding technological principles at 76%, developing solutions to achieve goals at 74%, formulating situations mathematically at 61%, and using concepts, facts, procedures, or reasoning at 61%.

Increasing student learning outcomes is one of the benchmarks in evaluating the implementation of the learning process. This research aims to test the effectiveness of learning models and approaches (PBL, PjBL, STEM) as well as teaching materials (E-modules and textbooks) in improving student learning outcomes. Where learning models and approaches and several types of teaching materials will be compared on student learning outcomes. So we will know the interaction of learning models and approaches and teaching materials used in influencing student learning outcomes. The research method used is comparative with experimental design. The samples used were 6 research classes selected using purposive sampling techniques. Research findings show that there is a significant influence between learning models and teaching materials on student learning outcomes, especially on the topic of biodiversity. Therefore, it is important to choose learning models and teaching materials that are relevant to the learning objectives.

Mount Ciremai National Park has an area of ±15,500 ha with soil characteristics at various heights and varied slope directions. This study aims to determine the characteristics of soil properties in Gunung Ciremai National Park based on slope direction and its relationship with vegetation growth. The method used in this study is a systematic sampling method based on height intervals on four slopes with depths of 0-15 cm and 16-30 cm. The results showed 1). Soil pH in all four slopes with different heights in the acid-neutral category, 2). The soil texture is classified as sandy-loam and sandy-clay loam, 3). C-organic content is classified as low-very high, 4). The content of N-Total is classified as low-high. 5). P2O5 content is classified as very low-low, 6). K content is classified as low-very high, 7). Ca content is low-very high, and 8). Mg content is classified as low to high. Significant correlation tests of soil physical and chemical properties are found on several parameters such as C/N ratio, K, and Mg.

In this rainy season the risk of contracting Dengue Fever increases. Many people control dengue fever chemically. The use of chemical larvicides has many disadvantages such as environmental pollution, resistance, and negative impacts on human health. This research aims to develop a natural larvicide from extracts of soursop leaves (Annona muricata) and tapak dara leaves (Catharanthus roseus). The study used a completely randomized design, with three replications. Soursop leaf and tapak dara leaf extracts were extracted using a maceration process using 70% ethanol solvent. III-IV instar Aedes aegypti mosquito larvae were used during the experiment, to assess the effect of formula (3 levels), dose (3 levels), and exposure time for 12 hours. All data were analyzed using Two-way ANOVA. The research results showed that the F1 formula and D3 dose were effective in eradicating mosquito larvae. Where the higher the concentration of soursop leaf extract and the higher the dose, the higher the mortality of mosquito larvae.

This research is a quasi-experimental research that aims to determine the effect of discovery learning model assisted by liveworksheets on the independence of biology learning of high school class XI students. The population in this study were all students of class XI MIPA SMAN 14 Makassar. The research sample was selected randomly (random sampling) so that two classes were obtained, namely class XI MIPA 6 as an experimental class that used the discovery learning model assisted by liveworksheets and class XI MIPA 1 as a control class with 33 students each. Data collection was carried out by giving a questionnaire of learning independence as many as 30 statement items with four answer choices. Data were analyzed by descriptive statistics and inferential statistics. The results of descriptive statistical analysis showed that the average value of the posttest in the experimental class was 86.09 higher than the average value of the control posttest which was 73.48. This study used covariate analysis (Anacova). Based on the results of inferential analysis obtained sig 0.001 smaller than 0.05. It can be concluded that the discovery learning model assisted by liveworksheets has an effect on the learning independence of biology students in class XI SMA.
