Abstract

Modern agriculture faces serious challenges due to its high dependence on chemical fertilizers, which in the long run leads to soil degradation, environmental pollution, and a decrease in the diversity of soil microorganisms. One of the innovative approaches that is now widely developed is the use of soil microorganisms as biological agents, especially Bacillus sp. This study aims to examine the role of Bacillus sp. in improving soil fertility and plant productivity in a sustainable manner through literature studies. A total of 25 relevant scientific articles published in 2015–2024 were thematically analyzed based on aspects of phosphate dissolution, enzyme production, biocontrol capabilities, and increased plant growth. The results of the study show that Bacillus sp. It has the ability to increase nutrient availability, inhibit plant pathogens, improve soil structure, and stimulate root growth through the production of phytohormones. However, its effectiveness is greatly influenced by the type of plant and the condition of the agroecosystem. With proper management, Bacillus sp. can be a leading alternative to reduce the use of chemical fertilizers and encourage sustainable agriculture that is environmentally friendly and efficient.

Abstract

Global climate change is causing increased seawater intrusion into coastal areas, triggering soil salinity that has a serious impact on the productivity of food crops, especially rice. This study aims to examine and compare the resilience of local rice varieties in Indonesia and Vietnam to salinity stress through a systematic literature review approach. The literature was collected from Google Scholar, Scopus, and ScienceDirect databases, with a range of 2010–2023, and analyzed using narrative synthesis and thematical-comparative analysis. The results of the study showed that varieties such as Sigambiri Merah, Inpago-8, and Ramos in Indonesia, as well as OM567, OM5451, and OM6976 in Vietnam have different levels of tolerance to salinity. The difference is determined by the expression of genes such as HKT1; 5, Saltol, OsMYB2, and OsNAC6, which play a role in the mechanism of ion exclusion, osmolite accumulation, as well as increased antioxidant activity. Marker-based breeding approaches and CRISPR/Cas9 technology have also strengthened the genetic resilience of plants. This study recommends the integration of molecular and agronomic approaches in the development of superior varieties to support food security in salinity-affected lands in Southeast Asia.

Abstract

Mahogany secondary metabolite is proven effective as lung disease medication, including COVID-19 through docking analysis. Therefore, this study aimed to identify total secondary metabolite from leaves, stem barks, and seeds of mahogany (Swietenia mahogany). The study was carried out using an experimental and descriptive method by observing the visual changes in the sample including color and foam formation, total levels of flavonoids, alkaloids, and saponins using Gas Chromatography and Mass Spectroscopy (GC-MS). Phytochemical analysis was analyzed to identify secondary metabolites namely flavonoids, alkaloids, tannins, triterpenoid saponins, and steroids. The results of the GC-MS analysis showed that mahogany seeds extract had the highest retention time, with a total of 46,484, containing alpha -D Glucopyranoside, 3-Penten-2-one, and gamma-Tocopherol. These compounds belonged to derivatives of flavonoids and saponins, serving as potential COVID-19 medication. The other were terpenoid, steroid, and fatty acid group compounds (alpha humulene, neophyte diene, n-hexadecanoic acid, 9- Octadecenoic acid, Octadecanoic acid, Squalene, and Stigmasterol). In conclusion, these identified compounds have the potential for COVID-19 medication due to their anti-inflammatory, antiviral, antimicrobial immunosuppressant, anticancer, and anti-asthma properties.

Abstract

Coleus amboinicus, known locally as torbangun, is a shrub from the Lamiaceae family that has thick stems, hairy green leaves, and a distinctive aroma. This plant is widely used in traditional medicine for various purposes, including increasing breast milk production and treating digestive disorders. C. amboinicus has great potential in developing pharmaceutical and nutraceutical products thanks to its active phytochemical content such as flavonoids, phenolics and essential oils. The potential for research development lies in further exploration of the bioactive contents of this plant and the mechanisms of its therapeutic action. Some examples of developments that can be carried out include clinical research regarding the effectiveness of torbangun in antimicrobial therapy, anticancer and immunomodulatory effects. In addition, optimization of extraction methods and more efficient identification of bioactive components are also potential areas for further research. However, the development of C. amboinicus also faces several obstacles, including a lack of clinical data supporting the safety of long-term use as well as obstacles in mass cultivation outside its natural habitat. More in-depth research is needed to overcome these challenges, especially in aspects of agronomy, biotechnology, and product formulation that meets modern pharmaceutical standard

Abstract

Rice Blast has been known as the main disease on paddy which has high severity leading to economic loss. Exploring rice resistance can be an effective way to improve productivity and prosperity toward this staple crop. This study aims to determine several local varieties which have potential for productions and resistances. This study used factorial randomized block design (RBD) consisting of 2 factors including plant spacing (25 x 25 cm; 25 x 30 cm; 25 x 40 cm); Upland rice variety MSP 17, Sigambiri Merah, Hamparan Perak and Kambiri Lumat. The results of the study reveal that variety has a significant effect on disease intensity especially Sigambiri Merah but not on Kembiri Lumat. However, there is no significant effect of spacing on blast intensity except in grain weight. Conclusion of this research was the varieties (V) selection of red upland rice is the best strategy to improve rice resistance toward blast disease. Keywords:  Disease density, Paddy, Staple Crop.

Abstract

White rice stem borer (Scirpophaga innotata) is one of the dangerous pests for rice (Oryzae sativa) because it attacks rice stems that can cause 50% loss of total production. The purpose of this study was to determine the pathogenicity of Entomopathogen Fungus Beauveria bassiana at different conidia dilutions (J), namely J1 (105), J2 (106), J3 (107), J4 (108), and J5 (109). The mortality of S. innotata larvae was tested with the density of B. bassiana of 2.08 × 106 conidia/ml. The effect of B. bassiana on the success transformation of S. innotata larvae to pupae for 14 observation day was also observed at the same B. bassiana density. This research resulted in the optimal pathogenicity of B. bassiana at dilution of 107 (treatment J3) which caused 100% death and 100% successful pupation. The lowest treatment was J5 (109 dilution) with a mortality rate of 50% and a successful pupation of 20%. The results of the probit analysis showed that the fastest average lethal time (LT50) value was found in treatment of 107 (J3) which reached 11.11 h. Keywords: Beauveria bassiana, Pathogenicity, Probit analysis, Scirpophaga innotata.
