This research was carried out in Durian Village, Padang Cermin District, Pesawaran Regency. The focus of the study was to identify the factors contributing to juvenile delinquency. Juvenile delinquency refers to the violation of rules or laws by teenagers. The behavior exhibited can range from minor offenses like skipping school or breaking school rules, to more serious offenses such as vandalism, gang fights, and drug use. The author utilized the Qualitative Descriptive method, which involves describing the phenomena observed in the field based on the actual conditions and using problem-solving procedures that are appropriate for these conditions. The Accidental Sampling technique was used to select samples based on certain considerations that were expected to provide the most comprehensive data. The findings of this study revealed that the predominant type of juvenile delinquency in Durian Village was the use of cannabis-type drugs. The lack of parental supervision and attention, as well as the absence of religious and moral values in the children's environment, were identified as the primary causes of juvenile delinquency. Teenagers resort to drug use due to the influence of their environment and peers who engage in deviant behavior, while having limited understanding of the dangers associated with drugs. The families of adolescent drug users in Durian Village were found to be unable to provide the necessary attention, affection, and care to their children, leading the adolescents to behave as they pleased without anyone taking an interest in their actions.

This study explores the role of microbial enzymes in the bioconversion of organic waste into renewable energy sources such as bioethanol, biogas, and biohydrogen. Employing a qualitative literature review, this research applies a systematic thematic synthesis to 28 scientific sources, including journal articles, policy reports, and textbooks published between 2018 and 2024. The findings indicate that enzymes such as cellulase, amylase, and lipase play a dominant role in the hydrolysis of organic substrates, breaking down complex biomolecules into glucose, amino acids, and fatty acids. These hydrolysis products are then fermented anaerobically by microbes like Saccharomyces cerevisiae and Clostridium spp. to generate various bioenergy outputs. In addition, the study highlights the importance of biochemical characteristics such as enzyme kinetics, stability, and substrate specificity, which are critical for improving energy conversion efficiency. Operational challenges include high production costs and suboptimal enzyme performance under non-laboratory conditions. However, promising innovations have emerged, including enzyme immobilization techniques, co-fermentation strategies, and the use of genetically engineered microorganisms. Case studies from India, Germany, and Indonesia demonstrate the practical potential of microbial enzyme-based bioconversion systems in transforming agricultural and household waste into valuable energy products. The integration of microbial enzymes into waste management not only reduces environmental pollution but also supports clean energy transition efforts. This research implies the need for policy alignment and educational curriculum integration in environmental science to accelerate public adoption and awareness.

The COVID-19 pandemic has accelerated the search for effective, safe, and sustainable antiviral agents. One promising approach is the utilization of natural chemical compounds derived from plants, microorganisms, and marine organisms. These compounds, such as flavonoids, alkaloids, terpenoids, and polyphenols, have long been known for their broad biological activities, including antiviral properties. This article aims to explore the potential of natural chemical compounds as new post-pandemic antiviral candidates through a systematic literature review of 28 scientific articles published between 2019 and 2024 from major databases such as PubMed, ScienceDirect, and SpringerLink. The findings indicate that 24 out of 28 reviewed compounds demonstrated significant antiviral activity, with 15 flavonoids targeting viral protease or spike protein through mechanisms like Mpro inhibition, ACE2 interaction, or cytokine modulation. Key challenges include low bioavailability, complexity in compound isolation, and lack of pharmaceutical standardization. However, advanced technological approaches such as nanoformulation, semi-synthetic analogue development, and the use of bio-refinery systems offer potential solutions to enhance the stability and effectiveness of these compounds. This article also highlights the importance of policy support and interdisciplinary collaboration in accelerating the translation of natural compounds from laboratory research to clinical application. The review offers practical implications for pharmaceutical innovation, particularly in biodiversity-rich countries such as Indonesia.

Recent developments in biotechnology and bioinformatics have opened new possibilities for designing enzymes for the halal food sector. This study employs an integrated framework combining in silico modelling and in vivo validation to create synthetic enzymes that are both effective and compliant with halal standards. Computational analyses were conducted to predict enzyme–substrate interactions and evaluate structural stability, while experimental validation confirmed enzymatic activity, thermal stability, and safety profiles. The results demonstrate that this dual approach improves design efficiency, enhances catalytic performance, and ensures enzymes originate from halal-certified sources, addressing a notable gap in current research where optimization and religious compliance are often addressed separately. This methodology bridges molecular biochemistry with Islamic jurisprudence, providing a scientifically grounded approach for producing bioenzymes suitable for industrial applications. By showing that halal verification can be integrated without compromising enzyme functionality, the study provides a model for ethical and religiously responsible food production. The findings have broad implications for the halal food industry, supporting scalable enzyme manufacturing and laying the groundwork for future research in synthetic biology, regulatory compliance, and the development of innovative functional foods.

This study aims to examine the effectiveness of Problem-Based Learning (PBL) supported by multirepresentation media in improving students' conceptual understanding of temperature and changes in the state of matter. A quantitative approach with a quasi-experimental pretest–posttest design with non-equivalent control groups was used. The research participants consisted of two classes of 11th-grade students majoring in science at SMA Negeri 1 Tumijajar, selected through cluster sampling. Data were collected through a test that measured seven indicators of conceptual understanding. The results showed a significant increase in conceptual understanding in both groups; however, the experimental group achieved much higher posttest scores and levels of improvement. The experimental group obtained an average N-gain of 0.68, while the control group achieved 0.49. Inferential analysis confirmed a significant difference in posttest scores between the groups, demonstrating the effectiveness of PBL supported by multirepresentational media in facilitating conceptual understanding. The improvement was particularly evident in higher-order indicators such as interpreting, comparing, explaining, and concluding. These findings suggest that the integration of multi-representation media in PBL is very effective as a cognitive scaffold to enhances students' ability to construct and translate abstract physics concepts, making learning more effective, meaningful, and cognitively structured.
