Abstract

Planting plants does not necessarily require a large area of ​​land, but can be done at home by utilizing existing yard space. Food is a primary life need that must be met. The utilizing of home garden as agricultural land can help fulfill the family's daily food needs. Apart from that, household organic waste can also be processed into organic fertilizer to support the growth of plants planted in the yard. People in Gambesi generally cultivate water spinach to meet their daily food needs and also to sell. The community wants the addition of other types of plants that are easy to develop. Apart from that, people need knowledge about making organic fertilizer to help fertilize the plants in their yards. Therefore, this community service is carried out with the aim of educating and socializing how to make liquid organic fertilizer from household waste and planting vegetables in home gardens to meet the community's daily food needs. Keywords: vegetable cultivation, home garden, organic fertilize

Abstract

Maggots are organisms in the second phase of the black soldier fly life cycle. Maggots move into the pupal phase which then turns into adult flies. Maggot (Hermetia illucens Linnaeus) is a black soldier fly larva that has a chewy texture, high protein, and has the ability to secrete natural enzymes that help improve the digestive system (Fauzi and Sari, 2018). The high level of nutrients contained in maggots, their abundant availability, their use which does not compete with humans and their easy-to-make growing media show good potential as an alternative combination of animal feed. The maggot cultivation training activity aims to train the younger generation to be able to participate in society in using maggots as an alternative animal feed. The activity was held on Monday 27 July 2020 to provide material and media creation which was attended by 18 participants. The care process until harvesting is monitored every week by the Community Service Team. Training activities are carried out in several stages, starting from preparing tools and materials, making media, the maggot cultivation process, and the harvesting process. It is hoped that maggots can be the answer to the problem of availability, namely the price of feed is cheap and easy to obtain, does not cause environmental pollution, and can increase the immune system of livestock.

Abstract

Trees are said to be healthy if they can carry out physiological functions and have an ecological ecology from various disturbances. The decline in tree health can be seen based on the condition of tree damage. This study aims to determine the health condition of trees and the type of damage in the Burung Bidadari Area, South Jailolo District, West Halmahera Regency. The study was conducted in September-October 2024. The method used is FHM (Forest Health Monitoring). Observations were made in two different clusters, namely cluster 1 Block A2 (production forest), cluster 2 Block A3 (protected forest). The level of tree health was analyzed according to the level of damage calculated based on the TLI and TDLI categories. Based on the results of the study, there were 3 families, 3 types of trees. There were 9 types of damage, namely Konk, growing konk, growing fruit with a total of 1 case. Open wounds with a total of 1 case. Resinosis/gymosis with a total of 2 cases. Termite nests with a total of 1 case. Loss of dominant tip, dead tip with a total of 2 cases. Broken or dead branches with a total of 7 cases. Damaged leaves, buds or tuna with a total of 13 cases. Leaves with non-green fruit with a total of 17 boxes. The results of the Tree Level Index (TLI) determine that cluster 1 is included in the healthy class (0≤5) and cluster 2 is included in the healthy class (6-10).

Abstract

Agarwood is a distinctive wood resin product extracted from the important genus of Aquilaria, but the population of agarwood-producing trees from natural forests in Indonesia is threatened due to over-exploitation, leading to an urgent call for conservation and sustainable uses. Molecular techniques such as DNA profiling have been used to ensure the legality, conservation, and sustainability of species from this genus. In this study, cross-species amplification of microsatellite markers initially developed for Aquilaria crassna was developed on two other closely related agarwood species (Aquilaria malaccensis and A. microcarpa), and their genetic variation was evaluated. The four loci (6pa18, 10pa17, 16pa17, and 71pa17) were used to amplify leaf genomic DNA from 55 trees across three Aquilaria species. The results showed that the four loci could successfully be amplified in A. malaccensis, A. microcarpa, and A. crassna. In addition, A. crassna exhibited higher genetic variation (Na=2.75, Ne=2.35, He= 0.5672, and F=-0.727) than A. malaccensis (Na=2.75, Ne=2.19, He=0.5424, and F=-0.598) and A. microcarpa (Na=2.50, Ne=2.11, He= 0.5234, and F=-0.734) indicated the transferability of microsatellite markers in closely related agarwood species, possibly due to the flanking region in these four microsatellite regions being well-conserved in several agarwood species. These findings indicated that the markers tested here can be considered an effective tool for future studies in population and conservation genetics to support the management of agarwood genetic resources and track its supply chain to prevent overexploitation.

Abstract

Ferns (Pteridophyta) are spore-reproducing vascular plants important in tropical forest ecosystems, and Indonesia is a global center of their diversity with over 2,000 species. However, fern diversity in North Maluku is still poorly documented. This study aimed to analyze the species composition and diversity of ferns as well as their implications for environmental sustainability in Fogi Village, Sanana District, Sula Islands Regency. The study was conducted across four habitat types: home garden, residential, riverbank, and mixed plantation, using purposive sampling with line transects of 1 km length and 10 m width. Data analysis included the Shannon-Wiener diversity index (H'), Margalef species richness index (Dmg), and species evenness index (E), complemented by a descriptive-ecological assessment to discuss implications for the sustainability of the local ecosystem. A total of 10 fern species were recorded comprising 229 individuals. The dominant species across habitat types were Pteris tripartita in home garden habitat (9 individuals) and Selaginella sp. in residential (15), riverbank (12), and mixed plantation (17) habitats. The residential habitat recorded the highest values of species diversity (H') and species richness (Dmg) compared to other habitat types. Species evenness (E) approached 1 across all habitats, indicating a relatively balanced distribution of fern species. Ecologically, the Fogi Village area retains potential to sustain its ecosystem functions; however, the low species richness recorded across all habitat types warrants attention in efforts toward sustainable environmental management of the area. In conclusion, the fern community at the research site shows a moderate level of diversity with a relatively even distribution of species across various habitat types. The high uniformity in all habitats indicates the absence of extreme dominance by a single species.

Abstract

Understory vegetation in tropical forests is shaped by interactions among canopy structure, microclimatic conditions, and soil edaphic properties. This preliminary study aimed to examine the relationships between understory vegetation and key environmental factors in a lowland tropical rainforest within the Khairun University Educational Forest, North Maluku - a critical but understudied secondary forest ecosystem in eastern Indonesia. Data were collected from ten observation plots through measurements of canopy structure, microclimatic variables, soil properties, and the composition and density of understory vegetation, including tree seedlings. Canonical Correspondence Analysis (CCA) was applied to explore how environmental variables explained variation in understory species composition across plots. A total of 37 understory plant species belonging to 18 families were recorded, with the community dominated by tree seedlings and understory palms. Five species dominate the understory layer: Caryota mitis, Saribus rotundifolius, Donax canniformis, Polyalthia sp., and Ficus hispida. CCA suggested exploratory associations between understory composition and environmental gradients related to elevation, canopy cover, soil moisture, and soil pH. However, permutation tests and forward selection did not identify any environmental variable as statistically significant, likely reflecting the limited number of sampling plots. Overall, the study suggests that understory vegetation patterns in this educational forest are related to combined environmental gradients rather than a single dominant factor. As a preliminary study, these findings provide baseline ecological information for further research on understory regeneration in this educational forest.
