Abstract

Human activities pose significant threats to the biodiversity of Indonesia, leading to a decline in the population of endemic animals. Insufficient awareness among the public regarding the importance of conservation exacerbates wildlife trafficking and decreases animal populations. To enhance awareness, early-age education is crucial. Hand puppets, as educational tools, offer an engaging and practical approach to teaching children about Indonesian fauna. The implementation of Fauna Hand Puppetry (FHP) was conducted at SDN 22 Kuranji, and through a series of hand puppets, illustrated storybooks, and QR-coded tags linked to a website, the socialization aimed to capture children's interest and provide easy understanding of the protected fauna. FHP products are designed with child-safe materials and attractively packaged, empowering children to take an active role in conservation. Socialization methods involve PowerPoint (PPT) presentations to explain Indonesian wildlife and interactive Q&A sessions to allow students to inquire and discuss the presented materials. Through a combination of presentations and Q&A sessions, this socialization effort is anticipated to foster a better understanding among students regarding the importance of protecting Indonesian fauna. The quiz and Q&A session results conducted after the socialization showed that students' understanding increased, and they could answer an average of 9 out of 10 questions correctly related to Indonesian fauna.

Abstract

Magnaphorte oryzae is a pathogenic fungus that causes blast disease in rice plants. This disease can cause a decrease in rice production. Therefore, it is necessary to control the disease, one of which is by administering microbes that are antagonistic to Magnaphorte oryzae. This research aims to determine the percentage of inhibitory power of Bacillus subtilis ATTC 6633 and Trichoderma harzianum on the growth of Magnaphorte oryzae with varying soaking times of 24, 48 and 72 hours on the Anak Daro rice variety. This research carried out viability tests for Bacillus subtilis ATTC 6633 and Trichoderma harzianum, as well as antagonist tests using the dual culture method. The results showed that the growth inhibition of Magnaphorte oryzae by Bacillus subtilis ATTC 6633 for a soaking period of 24 hours was 28.48% in the weak category, 48 hours was 32.27% and 72 hours was 31.01% in the medium category. Inhibition of Magnaphorte oryzae by Trichoderma harzianum for a soaking period of 24 hours was 50.63%, 48 hours was 57.59%, and 72 hours was 56.32% in the high category.

Abstract

The majority of Indonesian people consume rice as a staple food. According to data from the Central Statistics Agency (2022), rice production in West Sumatra reached 1,482,996.01 tons in 2019 and continued to decline until 2021, total rice production in West Sumatra was only 1,317,209.38 tons. This is inversely proportional to the population of West Sumatra which increases every year, so efforts need to be made to increase rice production. One of them is the biopriming technique to increase seed vigor. Priming is hydration carried out slowly which aims to ensure that the seed's water potential reaches balance and activates metabolism in the seed before the seed germinates. One of them is biopriming, which is a seed priming technique using biological agents in the form of beneficial microorganisms. Several factors influence the success of the priming technique, one of which is the soaking time. The right soaking time provides a deeper opportunity to absorb water to stimulate the seeds to germinate. This research aims to determine the effect of soaking time on biopriming of the local West Sumatran rice variety "Anak Daro" using Bacillus subtilis and Trichoderma harzianum on the germination of the Anak Daro rice variety. Completely Randomized Design (CRD) factorial pattern with 2 factors with 3 replications. Factor A is a biopriming agent, namely A1 (no microbes), A2 (Bacillus subtilis), and A3 (Trichoderma harzianum). Factor B is the length of soaking, namely B1 (24 hours), B2 (48 hours), and B3 (72 hours). The results showed that Bacillus subtilis and Trichoderma harzianum had a significant effect on maximum growth potential and germination, while soaking time had a significant effect on maximum growth potential and vigor index.

Abstract

Anthracnose disease caused by the fungus Colletotrichum sp. is one of the main problems in chili cultivation (Capsicum annuum L.) and can cause significant yield losses. The intensive use of chemical pesticides in controlling this disease has a negative impact on the environment and health. This study aimed to evaluate the antagonistic potential of phyllosphere fungi isolated from five medicinal plants, namely Phaleria macrocarpa, Curcuma domestica, Kleinhovia hospita, Hibiscus rosa-sinensis, and Morus macroura, against the pathogen Colletotrichum sp. Isolation was performed from leaf surfaces, and a total of 7 phyllosphere fungal isolates were tested using a double culture method with three replicates. The results showed that all isolates were able to inhibit the growth of Colletotrichum sp. through mechanisms of competition for space and nutrients as well as antibiosis, with inhibition levels ranging from high to very high. Among the tested isolates, Trichoderma sp. exhibited the highest inhibitory activity with an inhibition percentage of 92.78%, categorized as very high. Macroscopic and microscopic characterization supported the identification of several isolates belonging to the genera Trichoderma. This study concluded that phyllosphere ungi from medicinal plants have the potential as environmentally friendly biological control agents in combating anthracnose disease in chili plants.

Abstract

This study aimed to isolate, screen, and partially characterize protease-producing thermophilic bacteria from the Padang Dama hot spring, Solok, Indonesia. The main issue addressed in this study is the limited information regarding thermophilic bacteria capable of producing protease enzymes from this geothermal environment, despite their potential use in industrial processes requiring stable enzymes. Isolation was carried out using Nutrient Agar followed by incubation at 50 °C for 24 hours. Screening of protease activity was performed using Skim Milk Agar based on clear zone formation, and the proteolytic index (PI) was calculated to evaluate enzyme activity. Selected isolates were further characterized through macroscopic, microscopic, and biochemical analyses. The results showed that three isolates exhibited proteolytic activity, with isolate TUA-109 showing the highest proteolytic index, indicating superior enzymatic potential compared to other isolates. Partial characterization revealed that isolate TUA-109 is a Gram-negative, rod-shaped bacterium with positive catalase activity and motility, which are important traits supporting its adaptability and potential for enzyme production under extreme conditions. These findings highlight the potential of thermophilic bacteria from the Padang Dama hot spring as sources of protease enzymes, with isolate TUA-109 identified as a promising candidate for further investigation, particularly for industrial enzyme production. Future studies are recommended to optimize enzyme production and evaluate its application in industrial processes.

Abstract

This study details the development of a high-performance microbial fuel cell (MFC) utilizing a nanofiber-coated carbon anode, fabricated through the electrospinning of polyvinyl alcohol (PVA) integrated with carbon quantum dots (CQDs). A dual-chamber H-type MFC, with a working volume of 50 mL for both anode and cathode compartments, was operated in batch mode using sterilized sugarcane juice, adjusted to a pH of 7.0, as the organic substrate. Two electrogenic bacteria, Bacillus subtilis and Escherichia coli, were separately immobilized within the PVA/CQD nanofiber matrix to assess their electrochemical performance. Structural and chemical characterizations using SEM, FTIR, and UV–Vis spectroscopy confirmed the successful incorporation of CQDs and effective bacterial colonization within the nanofiber network. Electrochemical studies, such as CV and EIS, indicated low charge transfer resistance and improved electron kinetics especially when B. subtilis was present and an Rct of about 400 ohms. MFCs based on B. subtilis reached a maximum power density of 1754 mW/m² on day four of operation at a fixed external resistance of 100 0 and the electrode surface area of 9.45 cm², about 3.5 times greater than the power density obtained with E. coli (491 mW/m²). This has been due to the high performance of B. subtilis which can form a robust conductive biofilm, releases endogenous redox mediators, and has the ability to metabolize sugar rich substrates efficiently. These findings underscore the potential of PVA/CQD nanofiber-coated carbon anodes as an effective strategy for enhancing MFC performance and provide a promising foundation for future optimization and scale-up toward sustainable energy generation from organic waste at the laboratory level.
