One of the efforts made by the government in overcoming this problem is by carrying out Forest and Land Rehabilitation activities by involving farmers as local workers. This study analyses community participation in forest and land rehabilitation programs in Datar Lebuay Village, Air Naningan District, Tanggamus Regency. The research was conducted in June 2021. Data collection was carried out through interviews, observation, and documentation techniques. Respondents were determined using the Slovin formula with an error limit of 10%. The interview process uses a proportional simple random sampling technique. The data obtained were then analyzed descriptively quantitatively using a Likert scale. The results showed that there was several activities rehabilitation forest, namely: the planning subsystem with field technical design activities had a final value of 3, the implementation subsystem with a seedling, planting, and plant maintenance activities, with each final value of 3, except for plants which had a final value of 4 Monitoring and evaluation subsystem with monitoring and evaluation activities, with a final score of 3. The Forest and Land Rehabilitation (FLR) activities with community participation levels have Ordinary criteria (B). This shows that forest rehabilitation activities involving farmers are implemented correctly so that the land on which farmers are involved in rehabilitation activities is expected to be more sustainable.","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123696633","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}

However, the degradation of mangrove forests, especially conversion to aquaculture ponds is a driver for deforestation. Therefore, this study aimed to analyze the mangrove vegetation and duration of inundation in ponds before and after rehabilitation activities were conducted on abandoned ponds. In this analysis, we used the census method to collect structural data, the Important Value Index (IVI), composition and structure, and the diversity index. To determine the duration of inundation at the observation sites in a pond in Tanjung Rejo, Percut Sei Tuan village, we deployed one water logger and two Mini Buoys at ponds. At the observation site, eight pure mangrove species have been founded, namely Avicennia alba, A. marina, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, R. mucronata, R. stylosa, and Nypa fruticans. The main species was A. marina which is a total of 756 idv/ha at the seedling stage 52.81 idv/ha at the sapling stage, and 268.09 idv/ha at the tree level. The highest IVI has founded in seedlings, saplings, and trees at A. marina, which was 99.30%. 80.41% and 94.49%, respectively. Rehabilitated Avicennia spp that grew only 2.4% from 2000 seedlings. The low growth of seedlings was influenced by the pond condition which was always in a state of flooding. The current study provides important information that in carrying out planting or rehabilitation activities it is necessary to determine which inundation rotation should be a priority considered.","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131703876","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}

The flow of the Belawan watershed crosses 2 (two) regencies/cities, i.e., Deli Serdang Regency and Medan City. In more detail, Medan City is located in the Belawan Hilir Sub-watershed. Several main rivers in Medan have been polluted and shallowed, as a result of people's habit of littering the river. People who live around the Belawan watershed have a significant role in the sustainability of the river and its ecosystem services. This study aims to analyze the level of community knowledge of river ecosystem services in the Belawan Hilir sub-watershed and to measure the correlation between the community knowledge level and the behavior of river littering. The respondents were sampled using Simple Random Sampling, while the number of samples was calculated using the Slovin formula. Data was collected through structured interviews by compiling a list of questions (questionnaires). The correlation between community knowledge levels and behavior of river littering was determined using spearman correlation analysis. The community knowledge level was 63% (good category). There was a moderate-positive correlation between the community knowledge level and the behavior of river littering (0.512 correlation coefficient). Community awareness can be increased through online-based socialization using social media or by providing more waste management training programs.","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125801793","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}

Yellow bamboo (Bambusa vulgaris var. striata) is usually used for construction and craft materials. Hence, it is necessary to understand the characteristics of the culm. The study aimed to determine the predictor variables for the total internodes, and the distribution pattern of the length and bamboo wall thickness of the internodes on the yellow bamboo culms. The method used in this research was the method of destructive sampling for 30 bamboo culm samples. The samples were measured using a caliper for diameter at breast height and wall thickness, and measurement tape for the total length of the bamboo culm. For detail measurement, each sample was cut for each internode to be measured the length, diameter, and wall thickness of the internodes. The results showed that the predictor of diameter at breast height (dbh) is a predictor in estimating the total number of internodes on the culm resulting in an R2 of 0.631. While the total culm height as a predictor was able to explain the total number of internodes with an R2 value of 0.692. The length of the internodes pattern on the yellow bamboo culm from the bottom to the top side formed a bell curve. In the middle area of the culm, the length of the internode increased, but then it shrank back to the top side. The diameter and wall thickness patterns of the internode were non-linear. In addition, the predictors of diameter at breast height and total height are less accurate to explain the total number of internodes in yellow bamboo culms.","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131571453","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}
