Diseases caused by pathogenic bacteria such as Aeromonas hydrophila are a major health concern. However, the use of red betel leaves (P. crocatum) can serve as a potential solution to this problem due to their antibacterial properties. This research aimed to study the antibacterial activity of red betel leaf extract (P. crocatum), the structure and character of the bacteria inhibited by the extract, and the bioactive components present in the leaves. The results of the disc test showed that the average zone of inhibition was 14.28 mm, while the MIC test results revealed that a dose of 100 mg/L could inhibit bacterial growth (bacteriostatic). Moreover, the crude extract of red betel leaf (P. crocatum) damaged the cell walls and cell membranes of A. hydrophila bacteria, thereby affecting their character and structure. The UV-VIS analysis of red betel leaf extract (P. crocatum) and FTIR analysis with 96% ethanol absorption indicated the presence of flavonoids, saponins, tannins, and alkaloids. These findings suggest that red betel leaves can be used as a natural remedy to fight bacterial infections caused by pathogenic bacteria such as Aeromonas hydrophila
由嗜水气单胞菌等致病菌引起的疾病是一个主要的健康问题。然而，由于红槟榔叶（P. crocatum）的抗菌特性，使用红槟榔叶可以作为解决这一问题的潜在方法。本研究旨在研究红槟榔叶提取物的抗菌活性、提取物所抑制细菌的结构和特征以及叶片中的生物活性成分。药盘试验结果表明，平均抑菌区为 14.28 毫米，而 MIC 试验结果表明，100 毫克/升的剂量可抑制细菌生长（抑菌）。此外，红槟榔叶（P. crocatum）的粗提取物还能破坏嗜水气荚膜杆菌的细胞壁和细胞膜，从而影响其特性和结构。红槟榔叶提取物的紫外可见光谱分析和傅立叶变换红外光谱分析（96% 乙醇吸收）表明，红槟榔叶提取物中含有黄酮类、皂苷、单宁酸和生物碱。这些研究结果表明，红槟榔叶可作为一种天然疗法，用于抗击由致病菌（如嗜水气单胞菌）引起的细菌感染。

Media and teaching materials that suit learning needs can improve the quality of learning. The research aims to describe the use of media and teaching materials in science learning. The type of research is a survey. Research in June-September 2023 at Middle Schools in the Greater Malang Region. The research population was junior high school students and teachers in the Greater Malang area. The research sample was 584 students and 18 teachers. The data collection technique uses a media and learning material needs analysis questionnaire. The research instrument is a needs analysis questionnaire sheet. Data was analyzed descriptively, quantitatively, and qualitatively. The research results show that the media and teaching materials used by teachers are quite good, but teachers rarely use a variety of media and teaching materials. The learning media that teachers often use are learning videos and the teaching materials that are often used are textbooks. Science learning still requires supporting media and teaching materials, one of which is expected to be an e-module

This research aims to see the effect of the number of leaves left on the rootstock and the best defoliation time to improve the performance of cacao shoot connection seedlings. The research was conducted in the experimental garden of Politeknik Pertanian Negeri Payakumbuh from March to July 2023. Cocoa clone ICS was used as rootstock and clone TSH as scion. The experimental design was 4x4 factorial with 3 replications, the environmental design was completely randomized design. Data were analyzed statistically using F test and DNMRT further test at 5% level. From the research and data processing, it was found that there is an interaction between the treatment of different number of rootstock leaves and different defoliation times on the performance of cocoa shoot grafting seedlings based on the variables of percentage of grafted seedlings, number of shoots, number of leaves, leaf area and weight of seedling scion. It can be concluded that defoliation of the rootstock six days before splicing with rootstock having four leaves produces the best performance of cacao shoot grafting seedlings

The research uses a qualitative type with descriptive analysis methods: data collection techniques using interviews, observation, and documentation. The research results show that the cultivation of 4C skills is carried out through learning and school programs. Learning at nature schools uses a learning method: Learning with Nature (BBA). Through BBA learning, students are invited to identify problems and conclude problems related to learning. Students are also invited to form groups independently, divide tasks, work creatively, and communicate group work results. Instilling scientific literacy and 4C skills is also done through programs outside of learning. The planned programs include super camps, educational visits/trips, trading agricultural products, and Alek Minangkabau. The results of this research are the basis for conducting studies on instilling and improving 4C skills in elementary schools

Education in the era of digital technology has become a challenge for teachers and lecturers in how this technology can develop comprehensive knowledge and global insight. The purpose of this study is to improve learning achievement through the cognitive process of students in cell metabolism lectures using Interactive Digital Teaching Material (IDTM). The study involved 40 Biology Education students who were taking the third semester at one of the Private Universities in Bandung, West Java. The implementation of lectures and instruments to measure students' cognitive processes is based on the framework of the 1992 Marzano Learning Dimension. The results of the analysis showed that the N-gain value of Acquire and Integrate Knowledge and Extend and Refine Knowledge obtained a percentage of (28%-26%) on low criteria. While Using knowledge with a percentage of N-gain value (32%) on medium criteria. These results illustrate that IDTM facilitates students to train their cognitive processes toward better learning achievement

The andragogy approach is learning that directs students to independently solve problems. Students' low solving skills can be seen from the lack of student activity in the learning process resulting in low learning outcomes. The aim of the research is to determine the effect of the andragogy approach on students' problem solving skills in biology learning. The method used is quasi experimental. The research design is a pretest-posttest nonequivalent control group design. The research population was biology teachers in class XI and class XI high school students, totaling 239 people. The sample used a purposive sampling technique with a total of 144 students. Data on problem solving skills using case study questions and teacher interviews. Data analysis used the normalized gain test and independent sample t-test. The results of data analysis show that there is a significant difference between the average N-gain with a result of P = 0.001. The teacher's perspective shows that the andragogy approach improves students' problem solving skills. The research conclusion is that there is an influence of the andragogy approach on students' problem solving skills in biology learning

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes
