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.
