Abstract

Chili is an essential commodity in Indonesia, with demand continuing to rise; however, its production is often disrupted by leaf curl disease caused by viruses. One potential solution is using organic fertilizer enriched with beneficial microbes such as Plant Growth-Promoting Microorganisms (PGPM). Despite its potential, the role of PGPM in controlling viral diseases in chili plants has been rarely studied. This study aims to explore the effectiveness of organic fertilizer in reducing leaf curl infections by improving plant health. Two chili cultivars were used: 'Gama LBF' (a breeding product of PIAT UGM) and 'Ponirun' (a commercial variety known for its disease resistance). The chili plants were treated with various concentrations of organic fertilizer, and their effectiveness was evaluated based on disease incidence (the number of symptomatic plants) and disease severity (the level of visual symptoms), which were then converted into an index. Results showed that the 75% concentration yielded the lowest disease incidence in both cultivars—26.5% for 'Ponirun' and 42.85% for 'Gama LBF'. The lowest disease severity was also observed at the 75% concentration for 'Ponirun' and 50% for 'Gama LBF'. These findings highlight the importance of selecting the appropriate organic fertilizer concentration to suppress leaf curl disease in chili effectively.

Abstract

This study aims to assess the water quality of Pier 1 Kota Agung using macrobenthic community structures as biological indicators. Coastal areas such as Kota Agung Pier are increasingly exposed to anthropogenic pressures due to port operations, shipping activities, and surrounding land use. These pressures can subtly alter water quality and benthic community structure over time. A descriptive quantitative approach was applied across three observation stations representing the aquatic conditions surrounding the pier. Macrobenthos samples were collected using a Macrobenthic sample, which was carried out using a 10-inch core sampler and a 10mm mesh, for physical and chemical parameters. The identified macrobenthic organisms belonged to the classes Gastropoda, Oligochaeta, and Malacostraca, showing moderate diversity (H’ = 1.337–1.567), high evenness (E = 0.84–0.98), and low dominance (D = 0.24–0.37). The Family Biotic Index (FBI) values ranged from 3.81 to 3.86, indicating good water quality with low levels of organic pollution. Physical and chemical parameters such as temperature, water clarity, pH, and dissolved oxygen were within the standard quality thresholds. The study reveals that the environmental conditions at Pier 1 Kota Agung are relatively good, as indicated by balanced macrobenthic community structures and supportive physicochemical parameters.

Abstract

Crassochepalum crepidioides plant has antibacterial and anti-wound properties. This study aims to determine the botanical profile, microscopic powder, phytochemical screening, and Thin Layer Chromatography (TLC). This study aims to determine the morphology of leaves, stems, roots, microscopic powder, phytochemical screening, and Thin Layer Chromatography (TLC) of C. crepidioides leaves from Tanjung Setia Village West Coast Lampung, Indonesia. Methods include morphological examination, microscopic powder, phytochemical screening, and TLC. The results of the botanical show oval-shaped leaves, pointed tips, pinnate veins, serrated edges, smooth leaf surface, soft wood stems, and tap roots. Microscopic observation found fragments of stomata. Positive phytochemical screening of alkaloids, flavonoids, saponins, and tannins. TLC test spot with five spots (red) and an average Rf value of 0.21-0.97. Concludes that the thin layer chromatography test is thought to produce flavonoid spots at an Rf value of 0.72-0.77.
