Abstract

Silver Nanoparticles basically focus on the synthesis of nano-sized particles produced through chemical, physical, and biological processes, which contribute significantly to the control of plant and animal diseases and have shown considerable promise in improving the quality of human living conditions and health. The method of making silver nanoparticles, namely Green synthesis, involves the use of plants for the synthesis process of various types of nanoparticles. Green synthesis has the advantages of a simple method, environmentally friendly, non-polluting, antitoxic, and cost-effective. The purpose of this study was to determine the antibacterial and antioxidant activities of AgNPs. In the spectrophotometer absorption spectrum appears at a wavelength of 450 nm. FTIR measurements were used to determine the presence of bioactive molecules that may be responsible for the stabilization that acts as a capping agent. The absorption spikes at 3256, 1552, 1048, and 934 cm−1 were determined for gempur batu leaf extract, while silver nanoparticles showed absorption spikes at 3369, 1576, 1080, and 822 cm−1. The results of XRD analysis of AgNPs showed that they had been successfully synthesized, which can be seen from the formation of narrow peaks indicating the crystalline nature of the formed nanoparticles. The results of TEM analysis of AgNPs in this study are a mixture of spherical, hexagonal, and triangular shapes of silver nanoparticles. The antibacterial activity test of silver nanoparticles with gempur batu leaf extract with variations in AgNO3 solution concentration has been successful, which is indicated by the formation of inhibition zones for Eschericia coli and Staphylococcus aureus bacteria. The results of antioxidant activity in AgNPss show an increasing percentage of inhibition along with increasing concentration of AgNPss increasing from 1 to 15 ppm and ascorbic acid increasing from 1 to 5 ppm. Antibiofilm activity in AgNPs has a good ability to inhibit the formation of biofilm layers in Staphylococcus aureus and Escherichia coli bacteria by having a biofilm inhibition percentage of more than 50%.

Abstract

Fungal diseases pose a substantial risk to the health and productivity of rubber plants (Hevea brasiliensis (Willd. ex ​ A. Juss.) Mull. Arg., the primary source of natural rubber. The diverse fungal pathogens responsible for these diseases lead to significant economic losses in rubber plantations, threatening the global rubber supply. This review provides a comprehensive examination of major fungal diseases affecting rubber plants, focusing on their identification, scientific analysis, and management strategies. Conventional methods for pathogen identification, while valuable, often lack the efficiency and precision required for effective disease control. Recent advancements in molecular diagnostics, genomics, and biotechnology have greatly improved the accuracy and speed of pathogen detection, enabling more targeted and sustainable management practices. Integrated pest management, mainly through the use of disease-tolerant clones, is emerging as a viable alternative to chemical fungicides. Although chemical fungicides remain the most widely used solution due to their accessibility and effectiveness, their environmental impact and potential for resistance necessitate a shift toward sustainable practices. While biofungicides offer a more environmentally friendly option and are already in use, they are currently limited to small-scale plantations and have yet to be adopted for large-scale production. Efforts to develop resistant clones through molecular studies and advanced cloning techniques are ongoing, representing the most sustainable approach for combating fungal diseases in rubber plantations. By synthesizing current knowledge and advancements, this review underscores the pressing challenges in managing fungal diseases and the opportunities presented by innovative technologies. The findings aim to guide future research and promote the development of efficient, sustainable strategies for maintaining rubber crop health, ensuring consistent production, and safeguarding the economic stability of the rubber industry.

Abstract

Education should not merely provide students with knowledge; rather, learning in educational institutions serves as a process for acquiring knowledge, skillss, and competencies.  The researchers conducted preliminary research to identify teacher and students need in biology learning, as well as the levels of students' critical thinking skills, creative thinking skills, and collaboration skills. The instruments used in this research are questionnaire and test sheets. The data that has been collected will then be analyzed both quantitatively and qualitatively. The sample of the study are biology teacher and students in Fase D at SMAN 1 Kabila, Gorontalo Regency. Based on the analysis of student and teacher needs in biology learning, it can be concluded that the majority of students find the learning process difficult and monotonous. Although students exhibit good collaboration habits, 80% of them have never engaged in projects, and they desire the integration of technology into teaching materials. The results of critical and creative thinking ability tests indicate a "very low" category, highlighting the need for intervention to improve these skills, possibly through the implementation of active learning methods such as Project Oriented Problem Based Learning (POPBL). Therefore, the development of digital teaching materials, such POPBL-based E-Module (Project Oriented Problem Based Learning), is essential to enhance students' understanding, engagement, and critical thinking skills, creative thinking skills, as well as collaborative skills at SMAN 1 Kabila, Gorontalo Regency in biology learning.
