Institutional and community participation is an important aspect being the main pillar in the implementation of the rehabilitation of mangroves. There is rarely any failure in the mangrove rehabilitation because it is not supported by the institutional role to its full potential. This research aimed to inventory the role of institutions and community participation in mangrove conservation in the coastal zone, Tiwoho Village, North Sulawesi Province. Selection of study areas and respondents done by purposive sampling. Data colected by field observation and structured interview with key respondents by using the snawball method. Research showed that some institutions has a major contribution in initiating mangrove conservation in Tiwoho are public figures, village government, NGOs, religious institutions, institutions of formal education, and foreign researcher. The form of community participation in conserving mangrove among others are not cut down of mangrove wood for any reason planting seeds every oportunity and keep mangrove from other community disturbances. Several method of management are expected to be inspiration for stakeholders to be able developed a mangrove forest management system in different place which have similar characteristics.

Biomass estimation of secondary forests is required to support the emission reduction of carbon dioxide through an enhancement of forest carbon stocks. Commonly, forest biomass is indirectly estimated using tree biomass allometric models that are developed based on a destructive sampling of sample trees. The availability of biomass allometric models for secondary forests in Indonesia is still limited, particularly for secondary forest ecosystems in eastern Indonesia. This study aimed to develop allometric biomass models for mixed-species trees in a secondary forest of East Halmahera, North Maluku, and to compare their accuracies with some other allometric biomass models that commonly used for estimating biomass of secondary forests. The tree biomass measurement was conducted by using a destructive sampling of 18 mixed-species trees (with diameter range of 5,4 – 36,9 cm) in a secondary forest. The samples of each tree component (stem, branch, twig, and leaf) were analyzed in a laboratory to determine the biomass of each sample tree. Allometric models were developed by using a non-linear regression analysis, which were then compared with other allometric models. This study revealed that the biomass of mixed-species trees in the study area could be estimated accurately using the M7 model that used diameter, height, and wood density variables. Such local allometric model was more accurate than other allometric models commonly used for estimating tropical forest biomass. Alternatively, the M3 model that used diameter and height variables could also be used when wood density data was not available. The local allometric models from this study can enrich the availability of biomass allometric models for secondary forest ecosystems in eastern Indonesia.

Calophyllum inophyllum L. is one of species that has been identified as a source of oil suitable for biofuel, cosmetics and medicine. Until now, the propagation of this species uses generative methods. In the forest tree breeding program, after a plus tree is selected a vegetative propagation technique must be developed to maintain the genetic potential of the parent tree. This study was conducted to determine the growth response of selected clones in Provenance Seed Stand of C. inophyllum in Wonogiri, Central Java propagated using the grafting method. The research used was arranged in Randomized Completely Design with 22 clones as the parent tree treatments. Each treatment consisted of 5 grafted seedlings and repeated in 4 times. The results showed that the survival percentage of grafted seedlings ranges from 15 – 100 % at 2 months of age, which showed a fairly high variation among the selected clones. Increasing the success of the grafting technique on the C. inophyllum clones still needs to be done so that it can provide vegetative material for clone testing and operational planting. It is important to be conducted in order to produce C. inophyllum stands with high fruit productivity and oil yield.Keywords: Calophyllum inophyllum, vegetative propagation, seedling growth, nursery

Pranajiwa (Euchresta horsfieldii (Lesch.) Benn.) has been widely used as traditional medicine by the Balinese ethnic community. Up to now, the raw materials for traditional medicines from E. horsfieldii are harvested directly from their natural habitat. It is feared that it will interfere with its sustainability. The Balinese ethnic community has a culture known as the Tri Hita Karana (THK) concept, which means there is a balance in the relationship between humans and God, nature, and with fellow humans. This study aims to identify the use of E. horfieldii and its conservation efforts based on THK. This research was carried out in communities living around Bedugul, Bali. The method of data collection was done by participatory observation and semi-structured interviews. The research informants were 33 people with a purposive sampling method. The criteria are based on the level of knowledge and use of E. horsfieldii. Data were analyzed and interpreted descriptively. The results of this study indicate that E. horsfieldii has been widely used to treat various diseases and is practiced by many traditional healers (balian). However, people also use it for treatment without a standardized dose. This causes the measure of its use is very diverse. Harvesting of E. horsfieldii is carried out by the community while still observing the principle of sustainability according to the THK philosophy. Harvesting of E. horsfieldii is mostly done for individual needs. Although there has been a practice of buying and selling E. horsfieldii, harvesting has not resulted in over-exploitation. Efforts to conserve E. horsfieldii have been carried out by the community, especially the balians by trying to cultivate it, although they still fail. In addition, the conservation of E. horsfieldii is carried out by the Bali BKSDA with efforts to maintain the habitat of E. horsfieldii in forest areas.

There are 14805.14 ha of North Sulawesi coastal ecosystems that has been damaged. Baringtonia asiatica Kurz (Keben) is one type of coastal plants that can be used to protect coastal areas . Unfortunately, the propagation technique of Keben was not widely studied. This study aims to determine the characters of seedlings produced from the stumps of seed germination. The research used Complete Random Design with nine treatments, consisting of combination betwen three levels of root length (0 cm, 5 cm and 10 cm), and three levels of the stems length (5 cm, 15 cm and 30 cm). Parameters for analysis include percent of success, growth and quality index. The results show that root length and stem length factors significantly affect the height and robustness value. Treatment of root length of 10 cm and 5 cm rods allegedly produces the most excellent quality with the survival rates 93%, height 10.3 cm, diameter 1.08 cm, robustness value 2.03 and index of seed quality 1.35. Based on regulation of land rehabilitation, the height of 10 weeks stump have not qualified yet.
