Abstract

Research on the antibacterial potency of fresh extract from leaves of Jamaican cherry (Muntingia calabura L.) in inhibiting the growth of Shigella dysenteriae had been conducted in the Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University. The study aimed to determine the potential of fresh extract from  Jamaican cherry leaves in inhibiting the growth of S. dysenteriae and to determine its Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) against S. dysenteriae. The results showed that the fresh extract of Jamaican cherry leaves was potent as an antimicrobial agent against pathogenic bacteria S. dysenteriae. It was shown through 12 - 14 mm diameter of inhibition zone which was classified as strong inhibition. The MIC was measured at 3.125% while MBC was undetermined. According to these findings, it can be concluded that the fresh extract from Jamaican cherry leaves was potent to inhibit the growth of S.dysentriae at 3.125% concentration, yet unable to kill it.

Abstract

The research on antimicrobial activity of skin secretion derived from Rana hosii (Anura: Ranidae) against several pathogenic microbes had been conducted at Microbiology Laboratory and at Genetics and Biomolecular Laboratory, both in the Biology Department, Universitas Andalas. The research used to survey and experimental methods. The study aimed to determine the effectivity of Rana hosii skin secretion to inhibit microbial activity, hence it tested onto some pathogenic microbes such as Escherichia coli, Staphylococcus aureus and Candida albicans. The results showed that the biggest inhibition zone formed against E. coli was 10.96 + 0.63 mm, on S. aureus was 11.74 + 1.00 mm, while on C. albicans was 7.42 + 0.80 mm. The results indicated that the skin secretions from Rana hosii frog could be a potential broad-spectrum antibacterial, and antifungal activity against C. albicans.

Abstract

Ziziphus spina-christi (L.) Desf. is a member of the Rhamnaceae family, which has efficacy values as herbal plants used in traditional medicines. The spread of infectious diseases in humans has increased in recent years, raising public awareness of the importance of using traditional medicine as the first line of prevention against infectious diseases. This research aimed to determine the antibacterial activity of fresh extract, infusion, and ethanol extract and to determine the greatest inhibition zone of Z. spina-christi leaves against Gram-positive bacteria (B. cereus, B. subtilis, S. aureus, and S. epidermidis). This research used the survey method with a purposive sampling technique. The results showed that fresh extract, infusion, and ethanol extract of the Z. spina-christi leaves had antibacterial activity against Gram-positive bacteria (B. cereus, B. subtilis, S. aureus, and S. epidermidis) and the greatest inhibition zone was obtained from the ethanol extract with a strong inhibition category.

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

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

Priming is a seed-soaking technique to increase seed viability and also suppress pathogens' growth. Magnaporthe oryzae is one of the pathogens in rice plants that causes leaf blast disease. The high rice consumption each year in Indonesia is not proportional to the amount of rice plant production, which is affected by the growth of pathogenic fungi. This study aims to determine the viability and percentage inhibition of Bacillus subtilis and Trichoderma harzianum against the growth of the pathogenic fungus Magnaporthe oryzae on local West Sumatra rice varieties Ceredek, Pandan Pulau, and Batang Sungkai. The research was conducted by testing the viability of microbes by counting the number of colonies and testing microbial antagonists with the Dual Culture method on seven days of observation. The results showed that Bacillus subtilis and Trichoderma harzianum could inhibit the growth of the pathogen M. oryzae, which causes leaf blast disease. The viability of Bacillus subtilis after biopriming for 48 hours was most significant on Ceredek variety, which was 15.9x106 cfu/g, and for Trichoderma harzianum on Pandan Pulau variety, which was 0.4x106 cfu/g. The most significant inhibition percentage of Bacillus subtilis and Trichoderma harzianum was obtained in Ceredek rice with a value of 30.13% (medium category) and 63.04% (high category).
