The study's objective was to identify the different fungal species that were present at 10 ppt salinity levels, 10–20 ppt, and 20–30 ppt as well as the pace at which Avicennia marina leaf litter. The research method used litter bags filled with leaf litter of Avicennia marina (50 g) with 7 treatments, 3 replications and 3 levels of salinity. The A. marina leaf litter that had a salt level of 10 ppt had the highest level of decomposition. The dry weight of leaf litter left in the litter bag, which is 4.92 g on average. The largest dry weight of the remaining litter was found in an environment with a salinity of 20 – 30 ppt, which is an average of 10.42 g. The rate of decomposition of A. marina leaf litter in an environment with a salt level greater than 30 ppt is 6.53/yr (or almost equal to residence period of = 0.15 yr). The number of fungal species discovered in the leaf litter of A. marina, which goes through a breakdown process at salinity levels between 0 and 10 ppt and contains 9 species, is another way to observe the impact of salt level. In comparison to the large at salinity levels of 10 to 20 ppt and 20 to 30 ppt, respectively, there were populations of fungus that underwent the process of decomposition in A. marina leaf litter, with an average of 5.99 x 102 cfu/ml and 5.5 x 102 cfu/ml, the fungal population that was the highest concentration was 10.72 x 102 cfu/ml","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121561061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, protecting the mangrove ecosystem from degradation is very important. One effort that needs is ecosystem rehabilitation through mangrove planting in coastal environments. To support it, a design was devised using drones and remote-sensing vehicles to assist in making mangrove planting designs. This research was conducted in Jenggalu Estuary, Gading Cempaka District, Bengkulu City. This research aims to study the use of drones in mapping potential mangrove planting areas and designing a mangrove planting plan to rehabilitate coastal ecosystems. In mapping using drones, the height used was 80 meters with 80% overlap, and 2.87 hectares of potential mangrove planting area was obtained. Based on the research results, drones in mapping are very useful in calculating the area of potential mangrove planting areas and designing effective planting plans. There are four scenarios for planting mangroves with a spacing of 0.5 m, 1 m, 2 m, and 3 m, respectively. For a planting area of 2.87 ha, the number of seeds needed is 114,800 planting points for a distance of 0.5 m, 28,700 planting points for a distance of 1 m, 7,175 planting points for a distance of 2 m, and 3,189 planting points for a distance of 3 m","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130670742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most village communities around the forests of North Tapanuli Regency have used NWFPs for generations to meet their needs. This study aims to analyze the value of the contribution of NWFPs to the income of village communities to determine the level of community dependence on these forest resources. Knowing the value of the contribution of NWFPs can be used as recommendations for policymakers to allocate increasingly scarce NWFPs and distribute the benefits of NWFPs fairly and optimally. This research was conducted in five Districts in North Tapanuli Regency considering that there are still many people who live depend on NWFPs. The research method was carried out by field observations and interviews using questionnaires, with a total sample of 98 respondents. Respondents were taken using the purposive sampling method. Respondent identification was done through the snowball technique. Data analysis of the contribution value was carried out by calculating the total income of the community, such as incomes sourced from NWFPs and other income. The results showed that the monthly income of villagers outside of NWFPs was in the range of IDR 1,000,000 – 2,000,000.
