Abstract

Organic waste originating from restaurants brings problems to the environment because it can cause bad smells and environmental pollution. To reduce this pollution, organic waste can be decomposed and used as feed for black soldier fly (BSF) larvae can be useful as fish or poultry feed with high nutrition. Therefore, this research aimed to determine and study the feeding of organic waste, namely leftover rice and chicken bones, on the growth of BSF larvae. The resesearch was conducted using a completely randomized design (CRD) with 3 feeding treatments consist of leftover rice, chicken bones, and combination of leftover rice and chicken bones; and control treatment used T-51 pig feed. All teratments used triplicates. Data obtained from this study consist of BSF larvae growth parameter for 12 days, and proximate analysis of the feed and BSF larvae. Results showed that larvae fed with a combination of leftover rice and chicken bones was the best treatment to support the groeth of BSF larvae as shown by values of waste reduction index (WRI) 0,034 g/day, substrate reduction 51%, and 98 % of BSF larvae survival rate 98% in 12 days.

Abstract

The pandemic of COVID-19 disease in the late of 2019 resulted in the massive screening for drug discovery purpose. However, there is still no reports about the ability of natural products from bacterial group of class Actinobacteria as COVID-19 inhibitor. The aim of this research is to identify the potential ability of natural compounds from Actinomadura sp., the member of class Actinobacteria, against two receptors of COVID-19 protease with PDB ID 6LU7 and 5R7Y. The eleven natural compounds were docked using AutoDock Vina and the interaction between receptor and ligands were analysed using LIGPLOT. The most potential compound was simulated for its interaction stability using Yet Another Scientific Artificial Reality Application (YASARA) dynamics. The result of molecular docking by AutoDock Vina showed that Sagamilactam become the most potential inhibitor for viral protease as it had lower binding affinity (6LU7:-12 and 5R7Y:-10.4) compared to the both of  native ligand (6LU7:-11.4 and 5R7Y:-4.6). Furthermore, the interaction of the most potential ligand showed the low number of Root Mean Square Deviation (RMSD) deviation in molecular dynamic simulations. This result validated the docking method that used and indicated that secondary metabolites produced from rare actinobacteria of Actinomadura sp. have promising possibility to inhibit COVID-19 protease.

Abstract

The increase in soybean production and productivity has become a significant focus in the effort to meet global food demands. The use of environmentally friendly agricultural technologies and practices is a vigorously pursued strategy. Endophytic bacteria are one of the potential bioagents that can stimulate plant growth. The ability of endophytic bacteria to synthesizing the plant hormone indole-3-acetic acid (IAA) can be an alternative in the effort to enhance soybean plant productivity and ensure long-term agricultural sustainability. The objective of this study is to analyze diversity and ability of endophytic bacteria isolated from soybean roots to produce IAA. This research was conducted through several stages, including the isolation of endophytic bacteria from soybean root, evaluating the isolates' ablity  for IAA production, and characterizing potential isolates based on macroscopic and microscopic characteristics. This research indicated that a total of 11 endophytic bacteria isolates were obtained from soybean plant roots. Among them, four isolates, namely EAK4, EAK5, EAK6, and EAK8, demonstrated the capability to synthesizing IAA ranging from 35.46 to 44.56 ppm. These isolates showed various macroscopic and microscopic characteristics and hold promise as biological agents that promote planth growth.

Abstract

Diabetes is a health problem that exists throughout the world, especially in Indonesia. Based on data compiled from the International Diabetes Federation (IDF) in 2017, people with diabetes in Indonesia reached 10.3 million people, and if not handled properly it is suspected that there will be an increase to 21.3 million people in 2030. Curcumin analog compounds can used for the treatment of diabetes by inhibiting the enzyme α-glucosidase. The curcumin analog compound used in this study was synthesized from 4 methoxybenzaldehyde with cyclopentanone which was then called the CA2 compound. The α-glucosidase enzyme used in this study was obtained through extraction of weathered rice with an optimum pH of 4.5 and the enzyme extract fraction used was fraction II which had the highest activity compared to fractions I and III. The results showed that the values of the kinetic parameters Km and Vmax of the extracted α-glucosidase enzyme were 1.53 mM and 0.03 U/mL, respectively. The Km kinetic parameter value changed to 1.66 Mm while the Vmax value did not change when the α-glucosidase enzyme was inhibited by CA2 compound, so that the type of inhibition shown by CA2 compound was competitive.

Abstract

The Sawu Sea National Marine Park is a marine conservation area in East Nusa Tenggara Province that is known for its high marine biodiversity. The coral reef ecosystem in this conservation area is home to ecologically and economically important megabenthic organisms. Megabenthos are important regulators of marine ecosystems, acting as indicators of coral reef health. However, information on the types and densities of megabenthos in this conservation area is scarce. Research on megabenthos is critical for assessing coral reef health and informing conservation strategies. The aim of this study is to collect baseline data on megabenthos in the Sawu Sea National Marine Park waters surrounding West Kupang and Semau. The Benthic Belt Transect method was used to collect data at six locations throughout the marine park. The information was examined for species composition and density. To assess differences and relationships between locations and megabenthic categories, statistical tests such as Kruskal-Wallis and Pearson's correlation, as well as the Morisita index, were used. Four of the eight target megabenthic categories were identified in the study, with blue starfish and giant clams being the most abundant. There was no statistically significant difference in megabenthic density across locations or ecological and economic categories. The research uncovered potential habitat preferences among various megabenthic categories. The presence and distribution of megabenthos in the waters of this marine park provide important information about the health of coral ecosystems. These findings can help guide conservation efforts.

Abstract

Plant diseases become one of the dangerous threats to agriculture. Fusarium oxysporum is one of pathogen that attack many agricultural plants. The spread of plant pathogens must be controlled. One of the way to control plant pathogens is to use biological control methods by utilizing biocontrol agents using antagonistic fungi to control F. oxysporum. Antagonistic fungi can be found in various habitats such as rhizosphere soil that contains a lot of exudate released by the roots so that the area is rich in organic compounds. Sampling was carried out in the rhizosphere soil of Damar plants from the Baturraden Botanical Garden. Research on antagonistic fungi from the plant rhizosphere needs further exploration. Therefore, this study was conducted to obtain isolates of rhizosphere fungi that have potential as antagonists against F. oxysporum. This research was carried out with method stages ranging from sampling, isolation, characterization and identification to antagonism tests. The isolation results stated that five different fungi were found from the rhizosphere of the Damar plant. The fungi found were then tested for antagonistic ability against F. oxysporum and it was found that R5 isolate had the best ability to inhibit the growth of F. oxysporum with an inhibitory percentage value of 72.06%. This ability can be new information to be able to develop further about the potential of large plant rhizosphere fungi in their inhibition against plant pathogens.
