Agroforestry is a combination of forestry crops and agricultural crops.  Agroforestry management can not be separated from the active role of the community so that it is closely related to the role of men and women (gender) in managing agroforestry.  Sampling was carried out in September 2018 using the simple random sampling method. The method of data collection is interview using a questionnaire.  Data was tabulated and analyzed descriptively qualitatively using Harvard gender model analysis.  Agroforestry management activities carried out by farmers in Sungai Langka Village include pre-harvest, planting, maintenance, harvesting and transport activities and post-harvest activities (post-harvest activities and marketing).  The results showed men who opposed pre-harvest activities with a percentage of 93.95%.  This is because these activities are heavy work and require a large amount of energy so that they are suitable for work by men.  Women dominate pre-harvest activities such as post-harvest and marketing activities with a percentage of 93.02%.  This concerns this work is a light work and can be done while taking care of the household.","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114364880","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}

Local species was recommended because suitable to local climate and soil conditions, in this study we choosed toba benzoin (Styrax sumatrana) and suren (Toona sureni). The objective of this research was to get information about adaptability of toba benzoin and suren  on growth media containing tailings. Research was conducted in green hause Faculty of Agriculture, University of Sumatera Utara. Factorial Randomized Completely Design with two factor were used in this research. The first factor was growing media (Factor A) and the second factor was seedling species (Factor B). The observed parameter were seedling height, seedling diameter, seedling dry weight, primary root lenght, shoot-root ratio and chemical properties of media. \u0000The results showed that the species and growing medium significantly affected the height growth of seedlings, seedling diameter, seedling dry weight and length of the primary root.

The aim of the research was to analyze the carbon as a forest health indicator in Protection Forest, Reg. 25. The data were collected through cluster plot based on Forest Health Monitoring (FHM) method.  The calculus of the amount of stored biomass within the tree was referring to Ketterings, et al, (2001) is W = 0,11 x ρ x D2,62, mean while under growth and litter biomass are gained from total dry weight. Carbon sink is based on conversion number; 0,5 out of total biomass number. The average of carbon stored in Protection Forest Reg. 25 is about 939,12 ton/ha. Carbon within the stands are contributed the most; 937, 43 ton/ha, litter carbon about 1,06 ton C/ha and undergrowth carbon is about 0,63 ton C/ha. Based on the analysis, carbon can be a health indicator of Protection Forest Register 25 with the category of ugly, moderate, and good.  Cluster plots 1 and 2 included good category (1,232.75 ton C/ha -- 1744.13 ton C/ha).  As for cluster plots 3 and 4 included ugly category (209.97 ton C/ha -- 721.35 ton C/ha).","PeriodicalId":412108,"journal":{"name":"Journal of Sylva Indonesiana","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115917836","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}

In the first stage, “Jurnal Ilmiah Pertanian Kultura” published by Faculty of Agriculture USU has been targeted by faculty member of “Fahutan USU” for dissemination of their research results. This journal has been accredited by Directorate General of Higher Education in 2003 consequently its scope become specific, forestry science did not include therein. Hence, at that time, Program Study of Forestry Science under management of Faculty of Agriculture USU initiated the issuing of Peronema Forestry Science Journal in 2005 in order to accommodate scope of forestry science. Unfortunately the service and production of this journal become stagnant because most of the editorial staff pursued higher education in outside Medan city and the funding for publishing and printing vanished. In 2012, with the new spirit, Program of Forestry Science re-issued the new journal called “Foresta” Indonesian Journal of Forestry. It was a pity, the production process of this journal discontinued regarding to no submission of the manuscripts. All of the research results of undergraduate students of Program Study of Forestry Science have been uploaded into Peronema Forestry Science Journal in online version since 2014. In connection with establishment of organization structure of Faculty of Forestry completely, the publishing of JSI has been started in 2018 even though the editorial works of this journal has been begin since 2017, comprise call of paper, blind-review process, correspondence with the authors, layout and editing, including upload in the journal website. Supply of the manuscripts is provided not only from undergraduate research results of Faculty of Forestry’s students but also from the outside.

Sampling methods to estimate the potency of community forest are still rare. The size of community forest is relatively small, scatter, and less irregular shape, therefore the estimation of community forest potency using sampling plot is difficult to apply. The approach of sampling without a plot (plotless/ point sampling) was cheaper and faster compare to the method of sample plots and direct measurement (census) in predicting basal area. The objective of this research is determining the difference in the average value of basal area using direct measurement of stand (census) and point sampling methods. The research was carried out for 4 months in 30 community forests at Kemuning Village, Gunungkidul District. Materials used to estimate basal area with point sampling method were Spiegel Relascope and Bitterlich Stick with the value of Basal Area Factor 1. Parameters measured were diameter at breast high (dbh) for census method and the number of trees were categorized in or border for point sampling method. The result was analyzed statistically using unpaired t-student. The result showed that the average of basal area of tree in community forest with point sampling method were no significantly different from the average of basal area with census method (α = 1%).
