Abstract

The village forest of Desa Serdang, Barusjahe, Karo, North Sumatra, is a community-managed forest. This forest exhibits a high species richness comparable to state-conserved and managed tropical rainforests. The orchid group is particularly important to assess in any area, as it generally indicates forest quality with good biodiversity levels. This study employs an exploratory method to reveal 32 orchid species, consisting of 16 terrestrial orchid species from 13 genera and 16 epiphytic orchid species from 11 genera. Descriptions and identification keys for each species are provided in this paper.

Abstract

As Indonesia is known as a megabiodiversity country, and Sumatra is its second largest island, it is important to understand its ever-threatened plant biodiversity, including those managed locally as village forests. In Serdang Village Forest, Barusjahe, Karo, North Sumatra, we tried to list all the liana species and their phorophytes. We conducted a qualitative descriptive analysis of the lianas and their phorophytes in the study area and found There are 25 species of lianas from 14 families Mostly are leaners, followed by tendril climbers, root climbers, hook climbers, thorn climbers and twiners. They climbed on 8 species of phorophyte from 8 families, most commonly tall forest trees. This study enhances our understanding of the lianas and their phorophytes in the Serdang Village Forest, which can aid conservation efforts to preserve biodiversity.

Abstract

The reduction in the quantity and quality of food can occur during storage in warehouses due to the infestation of rice weevils (Sitophilus oryzae). Environmentally friendly control methods for rice weevil pests are needed, such as using botanical insecticides made from fragrant pandan leaf powder. This research aimed to determine the effects of fragrant pandan leaf powder insecticide on rice weevil pests. The research design used was a non-factorial Completely Randomized Design (CRD) utilizing four dosage levels: 15, 30, 45, and 60 g. The results showed that the dosages had a significant effect on rice weevil mortality, with the highest mortality rate found at the 60 g dosage, reaching 43.50%. The implications of the findings indicated that while higher doses of fragrant pandan leaf powder (60 g) significantly increase rice weevil mortality and also lead to rice weight loss, a balanced dose of bio-insecticide is needed to avoid excessive damage to the rice. Additionally, the organoleptic test results indicate that lower doses (15 g and 30 g) are more preferred by consumers for color, taste, and aroma, which implies that careful dosage control is crucial for both pest control effectiveness and maintaining consumer acceptance.

Abstract

Rubiaceae is a common forest plant family in Indonesia, including in many community-managed village forests such as the Serdang Village Forest in Barusjahe, Karo, North Sumatra. A thorough inventory of rubiaceous species is needed to understand their composition and usage by local people. This study aims to list all Rubiaceae species, understand their morphological characteristics, and document their utilization in the village forest. The exploration identified 18 species of Rubiaceae from 12 different genera. Nine species are utilized by the local community: four species as traditional medicine, two species as ornamental plants, one species for firewood, and one species for house/garden posts and household tools. This research enhances the understanding of Rubiaceae species and their uses in the Desa Serdang village forest.

Abstract

Each type of mangrove has specific stomatal characteristics, one of which is stomatal density. This stomatal density is directly proportional to the rate of evaporation, transpiration, and photosynthesis which is a form of mangrove adaptation to its environment. One of the external factors affecting stomatal density is light intensity which can vary due to canopy cover. This study aims to compare the stomatal density of Rhizophora mucronata Poir. in the Angke-Kapuk area, Jakarta, Indonesia. The location is a mangrove conservation area that has experienced a lot of environmental pressure, especially due to population growth and land conversion into settlements. Descriptive methods was used with transect sampling techniques at locations that represent very open and very closed canopies determined by purposive sampling. Stomatal sampling was carried out by applying a transparent nail polish on the lower surface of the leaf and then covering it with tape. The tape was observed using a microscope, and showed that Rhizophora mucronata Poir. has a low stomatal density. The results of the parametric independent sample t-test showed that the stomatal density of Rhizophora mucronata was not significantly different between very open and very closed canopy cover.

Abstract

Breast cancer is the second most prevalent cancer globally. One of the key pathways involved in breast cancer is the PI3K/Akt mechanism. A natural compound with potential that has not been extensively studied is Drynaria rigidula (Sw.) Bedd., a Polypodiaceous fern native to Indonesia and is commonly used in traditional medicine. This study aims to explore the potential of Drynaria rigidula as an anti-breast cancer agent. The method used in silico analysis by collecting data from several web servers such as SwissADME (https://www.swissadme.ch/) with the parameters Lipinski’s rule of five, Veber, Egan, and Way2Drug for biological activity. The protein used in this study is AKT1 (PDB ID: 6HHF), obtained from the RCSB database. Molecular docking analysis was conducted using PyRx software with visualization performed in Biovia Discovery Studio. The results showed that several compounds, such as 3,4-dihydroxybenzoic acid, fern-9(11) ene, Stigmasterol, dan Campesterol, had RMSD values < 3.0 Å and binding affinities of -9.4, -9.2, -7.6, and -7.6 respectively. These results were compared with the control ligand AZD5363 and doxorubicin, which had a binding affinity from each other are -8.3 and -7.4. Therefore, the docking results indicate that compounds from Drynaria rigidula are predicted to have potential as anti-cancer agents.

Abstract

Urban forest is an important urban feature with various services for human and non-human urban populations. We surveyed three age-size groupings in Cipayung City Forest in East Jakarta using nested quadrats. This urban forest harbours 7 species of sapling, pole and tree. As the highest number of species is in tree grouping, lower in pole, lowest in sapling; in the form of upside-down/constrictive age pyramid, plant species in Cipayung City Forest may need management plant replanting to maintain its biodiversity. The highest IV is Eucalyptus globulus, which may not be able to reproduce naturally in Cipayung. The highest IV in pole grouping is C. inophyllum with a very healthy population in every age-size grouping. The highest IV in sapling grouping is C. fruticosa, an ornamental species.

Abstract

The high levels of Pb in the water will affect the structure of fish liver organs. This study aims to determine changes in the macroscopic and microscopic structure of the liver organ of baung fish (Hemibagrus nemurus), as well as Pb levels in Siak River. Fish and river water samples were taken from Lima Puluh and Rumbai Pesisir Subdistrict. Histological preparation using paraffin method and HE stain. Pb levels using the Atomic Absorption Spectrophotometry (AAS) method. The macroscopic structure of the liver in Location 1 was yellowish red and Location 2 was brownish red. The average percentage of liver tissue damage in Location 1 was parenchymal degeneration (1.68%), hydropic degeneration (1.46%), fatty degeneration (30.77%), and necrosis (39.24%). Location 2 was parenchymal degeneration (1.20%), hydropic degeneration (1.35%), fatty degeneration (16%), and necrosis (21.70%). Fatty degeneration and necrosis damage are medium, and other damage is slight. The Pb level of Siak River in Pekanbaru City in 2024 was 0.113 mg/L (Location 1) and 0.072 mg/L (Location 2). Pb levels in Siak River have exceeded the standard limit of Pb in waters. High levels of Pb in the Siak River can damage the structure of fish liver tissue.
