Research on Growth Rate of propaguls of Rhizophora apiculata was carried out in Tanjung Rejo Village, Deli Serdang Regency, North Sumatra. The purpose of this study was to compare the growth of Rhizophora apiculata in two sylvofishery ponds. The parameters measured were height, diameter and number of leaves. During twelve weeks of observation, the height of the seedlings of Rhizophora apiculata was the best at ponds A, namely in the fifth week 1.8 cm with the best diameter increase of 0.2 cm, the highest number of leaves was 7 strands. At the ponds B, the highest increase in seedlings of Rhizophora apiculata was observed in the fifth week 1.8 cm, but did not experience any increase at all in the second week, with increasing diameters of about 0.05 - 0.1 cm, number of leaves range from 0 to 5 strands. This shows that the growth of Rhizophora apiculata is better at ponds A than at ponds B.

Agroforestry has been developed for community welfare. 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.

Watershed can become one of forest condition indicator. Lepan watershed belongs to main priority category in North Sumatera, the forest has a poor condition. This study aim to determine the degree of community participation possibility in the planning of restoration activities that will be done in Lepan watershed. This research used of the descriptif statitic analysis. The research shows that the possibility degree of community participation on forest landscape restoration activity is the high degree. The selection of the suitability of the plan species used is determined from the sum of the proportion of weight based on community perception and the analysis of natural forest vegetation.

This study aimed to determine the silvicultural techniques that applied by four farmers in private forest of white jabon and to know the growth of white jabon in Konawe. This study was conducted at four locations namely Sub District of Unaaha District of Unaaha, Wawoone Village, Tetemotaha Village and Langgonawe Village of Wonggeduku District, Konawe, Southeast Sulawesi Province. This study took place from May until October 2016, and was carried out in three phases namely choice of location, interviews with owners and Jabon stand inventory. The results showed that farmers in Konawe was planting white Jabon (Neolamarckia cadamba Miq.) without Jabon silvicultural techniques, special training. The farmersâ€™s knowledge cultivating through books, Internet access and other farmers. Silvicultural techniques which applied by farmers were included seedlings originating, land preparation, planting, and maintenance included replanting, weeding, fertilizing, pest and disease control and thinning.

Deforestation that occurs causes a decrease in soil fertility. Knowing soil fertility in the landscape will provide information on land management. The nature of the soil differs from one point to another, therefore it is necessary to map the properties of the soil. The purpose of this study is to map the distribution of the properties of forest land in areas that have been degraded. The land is a former privately-owned oil palm plantation in the Gunung Leuser National Park (TNGL) forest. The study uses a continuous grid interpolation method, thus forming polygons of soil properties. The soil types are Inseptisol an Ultisol. The results of the study show that most of them belong to the type of soil that is finely textured so that erosion can easily occur if surface runoff occurs in areas that have been exposed. The soil water content range that has the widest area is the range 26.98 - 29.50% with an area of 14.38 ha (42.91% of the research area). The range of land capacity has the widest area, namely the range 42.24 - 49.32% with an area of 13.32 ha (39.76% of the research area). Low organic matter content and acidic soil pH. Based on the results of these studies, the land in the research area is less fertile. However, restoration efforts are very possible because many tree species are adaptive with low soil fertility.

Gunung Leuser National Park is one of the world heritage forest located in Indonesia where the Government of Indonesia and the International world give serious attention to the condition of the area. Unfortunately the forest area of Leuser Mountain National Park significantly decreasing by years due to deforestation.. This study aims to determine land cover changes, the rate of deforestation and spatial characteristics of deforestation in the National Park Management Section Region VI Besitang Gunung Leuser National Park. Classification method was maximum likelihood classification (MLC). The results of this study indicated land cover changes from 2008 to 2016 at SPTN Region VI Besitang TNGL that forest has increased from 104.741,15 ha to 107.336,03 ha, mixed dryland agriculture has decreased from 3.690,40 ha to 2.498,53 ha, Palm oil decreased from 526,96 ha to 88,40 ha, and open land increased from 3.116,80 ha to 3.572,93 ha. The rate of deforestation in this area during that period is 221,14 ha/year or 1.769,12 ha. Factors that have a close correlation with the area of deforestation are the number of population and the number of families farmer; distance from road, river, settlement and plantation; height class, and slope class.

PT. Toba Pulp Lestari, Tbk is one of the industrial forestry companies with Eucalyptus as the main species. This research was conducted in a concession area located in Aek Nauli Plantation, Simalungun Regency, North Sumatra with an area of 22,533 Ha. The sample of this research is understorey species (height: 1.5 meters) under Eucalyptus stand in cycles 2, 3, 4 and 5 planted in 2015. To find out the composition of plant species, vegetation analysis was conducted initially by making minimum species-area curves to determine the number of plots. The placement of the sample starts with randomly distributed on plotted paths. The number of plots in each cycle is as many as 32 plots, 32 plots, 32 plots, 4 plots by 256 plots and 5 plots for 32 plots. The results of soil analysis found that secondary metabolic in eucalyptus soil classified into terpenoid which located at a distance of 50 cm (flat) and 100 cm (flat) from the tree at 2 years old Eucalyptus stand. The terpenoids also distributed in distance of 50 cm from trees with flat topography on 4 years old Eucalyptus stand. For 6 years old Eucalyptus stand, terpenoid distributed on 150 cm from a tree and there was also a saponin within 150 cm from a tree with sloping topography. If the dominant undergrowth grows were Strong and Senduduk, the secondary metabolism in the soil will be absorbed by this species.
