Vegetation is one of the factors that influence the protection function of the riparian zone. Riparian vegetation in teak production forests is dominated by teak plantation with low species diversity. Rehabilitation is needed to increase the role of vegetation in protecting riparian zone. Data and information of light intensity is required to support the success of rehabilitation. Light intensity is a significant factor for photosynthesis which impacts on the survival, growth and adaptation of a vegetation. The varying light intensity in the riparian zone due to diverse land cover becomes a challenge in rehabilitating this area. This study aims to identify light intensity in riparian zone of Modang River and Cemoro River in the teak production forest. Recognizing light characteristics will help in species selection to rehabilitate this area. Primary and secondary data were used in this study. Direct measurement of light intensity was carried out along riparian zone of the Modang and Cemoro Rivers by systematic sampling. A sampling plot measuring 20 x 20 meter was used as the location of the sampling point with a total of 36 plots. Climate data are obtained from field observations through the nearest climatology station. The results showed that different canopy cover causing light intensity of Modang and Cemoro rivers varies. Canopy cover in this area can be divided into canopy cover of teak forest of various ages (production plants), johar (previous rehabilitation plants), and logged-over areas. The selection of tolerant and intolerant trees is important to use as consideration for rehabilitation, in addition to other silvicultural and socio-economic considerations of the local community.Keywords: light, riparian, teak production forest

Screw tree (Helicteres isora Linn.) is a shrub species with 5 to 15 main stems where the natural distribution can be found in South Timor Tengah (TTS) regency of East Nusa Tenggara (NTT) province and it is potential as a medicinal plant. The fruits are the main material harnessed for traditional medicine or jamu. Recently, little is known on fruit productivity of screw tree under shaded and open area. At the field showed that there were differences on fruit and flower production under two shade condition and the main stems. The research aimed for gaining information on the effect of pruning on screw tree fruit productivity in the natural habitat under two shade conditions on fruit productivity. Split plot design was employed with two factors which were two shade conditions (shaded under trees and open) as a main plot and the pruning techniques as a sub plot. Pruning techniques had affected significantly on the number of shoots and fruits, and there was an interaction between treatments to the number of fruits. Shade conditions had an important role on fruit production. Plants grew under open space had better fruit characteristics on fruit length (46,94 cm), fruit diameter (6,41 mm), post-harvest fruit weight (0,94 g), oven-dried fruit weight (0,89 g) and lower water content (5,57 %), compared to under shaded space 44,16 mm; 5,73 mm; 0,87 g; 0,81 g and 6,95 %, respectively for fruit length, fruit diameter, post-harvest fruit weight, oven-dried fruit weight and fruit water content.

The objective of this research is to evaluate the ecosystem functions through vegetation and wildlife indicators. Methods used are vegetation analysis and direct indirect method to count wildlife . Results show that the dominant type of land coverage in Gunung Ambang Nature Reserve is open secondary forest, where shrubs, rattan, and epiphytes dominated. This might lead to vulnerability of the site toward disturbance. Furthermore, it was indicated that this area still contains local wildlife species such as Babyrousa babyrussa celebensis. Eventhough land degradation has become a significant issue, the status of Gunung Ambang as nature reserve has limited restoration attempts both vegetatively and mechanically.

The purpose of this study is to conflict mapping, explain conflict style of stakeholder and choices of conflict resolution. This study was conducted in February 2017 in Cisantana Village, Kuningan Regency. Data were collected through participatory rural appraisal; interviews, field observation, documentation and focus group discussions. The study method was used Rapid Land Tenure Assessment (RaTA) and Dispute Style Analysis (AGATA). The results showed that the dominant conflict in TNGC was the change of forest status which affected the economic activities of the community around TNGC, that involved eight dominant actor. In a conflict, the stakeholder has a different style of dispute. The stakeholders was facilitated and mediated to propose a permit to manage Patulungan (parking management), and a permit to manage Ipukan (tourism guide). In this case, the role of outsiders who do not have a conflict relationship is needed in order to realize conflict resolution.Keywords: conflict style,community, mapping, stakeholder, Ciremai Mountain

Kalapi (Kalappia celebica Kosterm.) is endemic in Sulawesi and Endangered species. Plant propagation needs to be done but is constrained by limited seeds. Vegetative propagation of plants can be an alternative method such as using the root cutting technique that has been done previously on other types of species. This study aims to determine the success of vegetative propagation of kalapi (K. celebica), an endangered tree species by root cuttings using Rootone F. as root growth regulator. The research took place from March to June 2019 conducted at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari. This study used a Randomized Block Design (RBD) consisting of 6 treatments of Rootone-F concentration: (a) 0 ppm, (b) 100 ppm, (c) 200 ppm, (d) 300 ppm, (e) 400 ppm and (f) 500 ppm. Each treatment was repeated three times and three units of the plant so that the total experimental unit used was 54 units. The results showed that the provision of Rootone-F could increase the success of the growth of kalapi root cuttings. Rootone-F concentration of 500 ppm gives the best results on the percentage of cuttings, percentage of sprouts, percentage of roots, number of shoots and shoot dry weight. The results showed that kalapi can be propagated by root cuttings.Keywords: root cuttings, Kalappia celebica, Rootone-F, Kendari

Most of primary forest after exploitation era in Indonesia was converted into secondary forest including Forest Management Unit of Poigar. On the other hand the understanding of forest vegetation will help ecology restoration efforts. This study aims to analyze the structure, composition and tree species diversity of Inobonto Poigar I. In order to accomplish the proposed objectives, 31 plots of 20 m x 20 m were randomly established in the forest area where number and name of tree species in each plot was identified and counted. The research was conducted on September 2014 and recorded a total of 78 species within measured plot. The average basal area of the forest was 16,77 m2/ha and the size class distribution was different from primary forest which is resembled a reserved J-shaped pattern. Trema orientalis was found as the dominant species among tree and pole levels, whereas Piper sp. dominated sapling level respectively. The Shannon-Wiener index showed that sapling has the higher diversity than tree and poles. The result of structure and composition analysis of vegetation has indicated that Inobonto I forest is secondary forest.
