Mon, 14 Apr 2025 00:00:00 +0700

The existence of the Patuguran mangrove estuary area which is currently a great potential in the development of ecotourism can be a threat to the diversity of bird species that exist so that this study was conducted with the aim of knowing the richness of bird species and types of plant-eating bird communities in the Patuguran mangrove area of Pasuruan Regency which is expected that this estuary area is able to support the existence of birds with high diversity. Bird data collection was carried out in October 2024 using the point count method at 2 location points in the estuary area and the middle of the Patuguran Mangrove Area and data analysis using the Margalef species richness index. The results showed that the species richness index (R) value was 4.63 which was included in the high species richness category, while the feeding guild type of the bird community found was 8 species, namely Insectivores (33%), Carnivores and Insectivores (24%), Carnivores (15%), Fragivores (9%), Granivores (9%), Insectivores and Fragivores (3%), Nectivores (3%), and Omnivores (3%).

Cardiovascular diseases are a leading cause of global mortality, necessitating the exploration of safe and effective treatments. Ginkgo biloba, an ancient medicinal plant, has gained attention for its potential in managing cardiovascular health. This review explores the pharmacological mechanisms of Ginkgo biloba, focusing on its cardiovascular benefits. This review aims to understand the pharmacological mechanisms of Ginkgo biloba in addressing cardiovascular diseases. The method used in this review was a systematic review conducted through the PRISMA guidelines. Ginkgo biloba contains bioactive compounds, including flavonoids, terpenoids, and polysaccharides, that exhibit anti-diabetic, anti-inflammatory, anti-fatty liver hemorrhagic syndrome, anti-oxidant, anti-depressant, and anti-cancer. In conclusion, Ginkgo biloba offers a promising therapeutic solution for cardiovascular desease.

This study aims to compare the salt content (NaCl) in the leaves of several types of coastal plants that grow in different formations, namely Mangrove, Barringtonia, and Pres-Caprae. The study was conducted in the coastal area of Lais District, North Bengkulu Regency using direct survey methods in the field and laboratory analysis using a refractometer. The results showed that there were 10 species of coastal plants from three formations, namely Barringtonia, Mangrove, and Pes-Caprae. The highest salt content was found in the Acanthus species ilicifolius (2.75‰) from the Mangrove formation, while the lowest levels were found in Canavalia maritima (0.75‰) from the Pes-Caprae formation. The difference in salt content is thought to be influenced by the location of its habitat in the coastal area and its ability to adapt both structurally and physiologically so that it can survive in an environment with extreme salt content. The results of this study provide important information about the adaptation of coastal plants to salinity and can be the basis for further research on salt concentration in coastal plants.

Effect of auxin induction on root induction of Granola potato cultivar

Bekti Isnaeni — Wed, 30 Apr 2025 00:00:00 +0700

Potato is one of the horticultural crops that contains high carbohydrates so it needs to be developed because it has prospects for food diversification. However, in the breeding of potato plants there are obstacles found, the application of biotechnology in the form of in vitro culture or micro-breeding of potatoes is an alternative to overcome these obstacles so that high quality potato tubers can be produced. The purpose of this study was to determine the effect of auxin hormone on root induction of granola cultivar potato. This research is an experimental research with the research parameter is the number of roots of Granola variety potato plants for 2 weeks of observation. The results showed that the addition of auxin hormone to the root induction of potato plants affected the number of plant roots. This can be seen from the first week, October 1, 2022, root growth has occurred. Overall there was growth and increase in the number of roots from October 1 to October 13, 2022. So it can be concluded that auxin has a positive effect on root induction of Granola cultivar potatoes.

Types of Ferns (Pteridophyta) in the Oil Palm Plantation Area, Rambahan Village, Pasaman Regency as a Contribution of Teaching Materials to Biodiversity Material Phase E SMA/MA

Ferns are a division of plants that are distinctly characterized by three primary parts: roots, stems, and leaves. However, ferns do not produce seeds. In Rambahan Village, located in Pasaman Regency, there are privately managed oil palm plantations that are often overrun with ferns, some of which have become weeds to the oil palm crops. The specific species of these ferns remain unidentified by the local community. This study aimed to identify the species of ferns in the oil palm plantations of Rambahan Village and to produce a book as a contribution to biodiversity education materials. The research, conducted from August to September 2024, was descriptive in nature and employed an exploratory survey method. Results revealed the presence of 19 fern species (Pteridophyta) in the plantation area, including Vittaria costata, Adiantum latifolium, Vittaria lineata, Davallia denticulata, Oleandra neriiformis, Phymatosorus scolopendria, Goniophlebium percussum, Tectaria fuscipes, Asplenium dimidiatum, Asplenium nidus, Thelypteris palustris, Nephrolepis biserrata, Nephrolepis cordifolia, Stenochlaena palustris, Dryopteris filix, Dryopteris carthusiana, Diplazium esculentum, Selaginella plana, and Lygodium palmatum. The resulting book serves as an educational contribution to biodiversity studies.
