Abstract

The Sawah Tambak Rice-Fish Farming System is a land-use practice that alternates between rice cultivation and fish farming depending on the season. During the dry season, the land is used for growing rice, while in the rainy season, it functions as a fishpond. Successful rice cultivation in this system relies on beneficial rhizosphere bacteria that interact with plant roots through biological, physical, and chemical processes. This study aims to characterize bacteria isolated from the rhizosphere of rice plants (Oryza sativa L.) in this system and evaluate their ability to produce indole-3-acetic acid (IAA) and solubilize phosphate. Bacterial colony identification was performed using the streak plate method, IAA production was measured via spectrophotometry, and phosphate solubilization was assessed using the phosphate solubilization index (PSI). The results showed diverse bacterial isolates with distinct morphological, biochemical, and physiological characteristics. Several isolates exhibited strong IAA production, with B3 reaching the highest concentration (18.29 ppm) on the sixth day. Phosphate-solubilizing bacteria (PSB) were also identified, with B4 and S5 showing the highest PSI values of 6.06 and 5.3, respectively. These findings suggest that rhizosphere bacteria in the Sawah Tambak system have the potential to enhance rice growth by improving phosphorus availability and producing plant growth hormones, contributing to sustainable and environmentally friendly rice cultivation

Abstract

Penelitian ini bertujuan untuk memanfaatkan limbah bonggol jagung sebagai sumber energi alternatif melalui pembuatan briket. Di Desa Kedungbanjar, Kecamatan Sambeng, Kabupaten Lamongan, masyarakat masih belum mengoptimalkan penggunaan limbah ini, yang berpotensi mencemari lingkungan. Metode yang digunakan dalam penelitian ini adalah Asset Based Community Development (ABCD), yang melibatkan masyarakat dalam setiap tahap pembuatan briket. Program ini diimplementasikan melalui sosialisasi, pelatihan, dan praktik langsung untuk meningkatkan pengetahuan dan keterampilan masyarakat. Hasil penelitian menunjukkan bahwa briket dari bonggol jagung dapat mengurangi limbah pertanian sekaligus memberikan nilai ekonomi tambahan bagi masyarakat. Dengan demikian, program ini tidak hanya berkontribusi pada keberlanjutan lingkungan tetapi juga meningkatkan kesejahteraan masyarakat Desa Kedungbanjar.

Abstract

Dengue is caused by the dengue virus (DENV) and being prevalent in 100 tropical and subtropical countries including Indonesia. This disease is spread by Aedes mosquitoes. There is currently no clinically authorized medicine to treat the dengue fever. Physalis peruviana has ethnomedicine application and noted for its antioxidant activities. This study purpose to investigate the pharmacokinetics or ADMET of anti-DENV from leaf parts of P. peruviana. The phytoconstituents data were gathered from multiple sources. The drug property and ADMET prediction were assessed using pkCSM. Following online screening, 3,3-dimethyl-octane functioned as predictive anti-DENV therapeutic candidate. Further dry and wet lab studies are needed to validate this finding.

Abstract

Curvularia andropogonis is a plant pathogenic fungus that causes red spot disease on citronella leaves it infects. This fungus can cause long splotches along the tips and edges of leaves which can result in damage to the entire leaf. In citronella plants, anatomical analysis is needed in the form of analysis of the value of the number and density of stomata and trichomes. Stomata are one of the structural defenses for plants against environmental stresses such as pathogenic infections. In addition to stomata, trichomes also contribute to plant defense and have a protective function. This study aims to analyze the influence of C. andropogonis fungal infection on changes in the anatomy of the epidermal tissue of citronella leaves and to determine differences in the density of stomata and trichomes in normal citronella leaves and citronella leaves infected with C. andropogonis fungus. This research method uses analysis of the number and density of stomata and trichomes using paired t test. The results showed that the average stomata density of healthy citronella leaves was ±470 stomata/mm2 and after being infected, the average density was ±312 stomata/mm2. The average density of healthy citronella leaf trichomes was ±267 trichomes/mm2 and after infection the average density was ±222 trichomes/mm2.
