This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %, average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).

Bamboo is a multipurpose plant that has been used by the people for generations. This study aimed to describe the processing of bamboo and analyze its added value in Tasikmalaya Regency, West Java. Data was collected in April -December 2016 through interviews using questionnaires and field observations of bamboo craftsmen, and then were processed and analyzed quantitatively and descriptively. The community processed bamboo into woven products such as ayakan, boboko, haseupan, hihid, picnic basket, nyiru, pipiti, and parcel, as well as non-woven products such as piggy banks, key chains, glasses, wall clocks, lampshades, invitation boxes, bowl, cup, frame, teapot, letterbox, and tissue box. The average added value of woven products was IDR 131,197.21 or 9.11 % of the non-woven products, which was IDR 1,439,742.42. The average added value ratio of woven products is 0,83 and 0,90 for non-woven products. Bamboo woven business for household products is mostly done because the market has formed, stable, and has a wider scope even though it has lower added value. The market of non-woven products is smaller and specific even though it has a higher added value. A bamboo stem is only valued IDR 10,000 – 50,000, so it should be sold in processed products rather than the original form.Keywords: bamboo, processing, added value, woven, non-woven

The utilization of land together between trees and crops is one of the strategies in land rehabilitation program in Indonesia. High pressure from people living surrounding the forest land required the forest managers to invite more participation from the people in managing the forest land. Agroforestry pattern with certain tree species chosen by forest managers together with certain crops preferred by the communities may become the solution for all stakeholders’ interests in a high-pressured forest area. One of the considerations in agroforestry development is economic aspect. This study aims to analyze the financial feasibility of agroforestry pattern auri (Acacia auriculiformis) and peanut, pigeon pea, and corn in Batulanteh forest management unit (FMU) in Sumbawa, West Nusa Tenggara. The feasibility assessment criteria used in this study were Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit Cost Ratio (BCR). The result of this study showed that agroforestry pattern of auri with paddy, peanut, pigeon pea and corn is financially feasible with the NPV, IRR and BCR values are IDR14.607.837.-, 53 % and 1.51 respectively. Keywords: agroforestry, paddy, peanut, pigeon pea, corn, dry land

Tiwoho mangrove forest islocated in north coast of North Sulawesi province.This area functions as life buffer system for community and sustainability of Bunaken National Park. Due to the important and strategic roles of mangrove in protection and ecological functions, therefore, it is needed to know scientific information about mangrove population dynamics. This research aims to know the vegetation composition and structure vegetation of Tiwoho mangrove forest. Data collection used 20x20 m sample plots that were sistematically laid from the sea to the land side up to the highest tidal line. Distance between plots along 25 m. Results showed that at tree level Sonneratia alba had the highest Important Value Index (IVI) of 206,88 % and Brugueira sp of 46,06 %. Although Rhizopora apiculata value is lower than Brugueira sp. But the values of relative frequency of these species are almost similar. It means that both species are frequently found in observation plots. Rhizophora apiculata dominate at pole and sapling levels, but frequency of occurance this species is lower than Brugueira sp in pole level.

The purpose of this study is to evaluate the texting, sharing, and mentoring (TSM) method as an innovative method of community empowerment applied in 'Go-Honey' program. This method is mixed offline and online with the use of Whatsapp groups connecting program participants, resource persons, and local mentors. Using the Bloom's Taxonomy approach, this study compares the knowledge level of the 'Go-Honey' program participants implementing TSM with other sitngless beekeeping program participants who use the single-face-to-face (TTM) method as a control. The total participants involved in this study were 20 people, half of whom were female members of 'Go-honey', while the other half were not. Participants were asked questions related to cognitive, affective and psychomotor aspects by direct interviews. Observations were also done on the results of the work performance. The results show that the 'Go-Honey' participants have a higher level of knowledge about stingless beekeeping compared to the control model in these three aspects of knowledge. The results of the Mann Whitney test shows that the cognitive, affective and psychomotor scores are significantly different at 1 % alpha. This method has the potential to be applied after the pandemic ends with the principle of distance learning as long as there is the internet connection and the presence of local mentors.Keywords : Bloom’s Taxonomy, knowledge transfer, Whatsapp Group, gender, blended learning, distance learning

One of state forest areas managed by three management regimes is Bunder forest area, Gunungkidul, Yogyakarta. Three management regimes are the production forest of KPH Yogyakarta, the conservation forest of Tahura, and the educational forest of KHDTK Wanagama I. The differences of management regimes are thought to affect the actual interaction pattern of villagers with the forest. This research aims to compare the actual rights and access of villagers to Bunder forest area in three management regimes in the hope of finding more effective forest management patterns. This research used a qualitative approach through the case study method of the interaction villagers of Bunder, Banaran, Ngleri, and Gading villages with the surrounding forests. The results show that forest management regimes affects the way villagers can access the forests. The aggregate value of the actual rights received by the villagers to the production forest of KPH Yogyakarta is higher than the educational forest of KHDTK Wanagama I. The lowest is management regimes in conservation forest of Tahura. Based on the access mechanisms that empower villagers, the educational forest regime of KHDTK Wanagama I is higher than the production forest regime of KPH Yogyakarta and the conservation forest regime of Tahura. This research recommends defining rights and access to increase certainty about the benefits of forest resources.Keywords: rights, access, production forest, Forest park, educational forest

The procurement of good quality seeds for the development of mindi (Melia azedarach L.) in the community forest is absolutely necessary. The purpose of this research is to investigate the diversity of the viability and seedling vigor of mindi from different populations with various treatments of dormancy breaking. The sample materials were mindi seeds that were collected from 6 locations (6 seed lots) or seed sources which were located in the community forest of West Java. There are 10 treatments of dormancy breaking that were applied in this study. The experiment design was Randomized Complete Design (RAL). The breaking dormancy was focused to the delignification of hard seed coat. Results showed that the most effective dormancy breaking for mindi seed was soaking in consentrated Sulfuric Acid (H2SO4) as long as 30 to 45 minutes. The first count for germination of mindi was on the 16 day and the final count was on the 31 day.The average value of germination percentage (DB) for all seed sources was 40 %, while the highest which is 60% was mindi from Sumedang seed source. The highest value of germination rate that is 6,543%/etmal was seed from Sumedangand seed from Gambung was the lowest (1,400 %/etmal). Keywords : community forest, Melia azedarach L., variation, viability, vigor.
