Wood anatomy of Shorea mujongensis P.S. Ashton was investigated in order to ensure this species belongs to yellow meranti group. Such study is very important since this species is already listed in the red list of IUCN and classified as critically endangered species. The microscopic slides were prepared according to the Johansen's method, while the anatomical features observed according to the IAWA List. The results show that S. mujongensis wood exhibit brown heartwood, light brown sapwood, rough texture, straight grain sometimes interlocked and somewhat rough. The main microscopic characters are growth rings indistinct; vessel diffuse, mostly solitary, rounded to oval; simple perforation plate and alternate intervessel pits; parenchyma scanty paratracheal to thin vasicentric; axial intercellular canals in long tangential line, radial intercellular canal and vasicentric tracheids present; rays uniseriate and multiseriate, prismatic crystal in procumbent cells; fiber length 1,294 µm, diameter 26 µm and wall thickness 4µm. Macroscopic and microscopic observation of S. mujongensis wood confirms the species belongs to yellow meranti group. The assesment on fiber dimensions and derived values of the wood fibers classified the wood into class quality II. It indicates that this species is moderately favorable as raw material for pulp and paper manufacture.

Producing seeds in seed orchards that retain a broad genetic diversity is important for the continued development of a species. The aim of this study was to find out the genetic diversity of, and genetic relationships between several populations of sengon (Falcataria moluccana) in the Candiroto seed orchard in Indonesia. Analysis using twelve single nucleotide polymorphism (SNP) markers showed that the total population had a high level of genetic diversity (He = 0.359±0.128); the Wamena population in Papua had the highest level. The close genetic relationship between this and the population from East Java suggested that the latter may have been introduced from Wamena. There was also a close genetic relationship between the populations from Central and West Java and that from Mindanao Island in The Phillipines. The high genetic diversity of sengon in the Candiroto seed orchard provides a good basis for selection and breeding.

Gaharu wood stand has an important source of profits to the forest community in South and Southeast Asia tropical forest countries, but Aquilaria species have reduced in number and turn out to be endangered due to overexploitation. Today, the planting stocks of Aquilaria species are not sufficient to sustain the yield of gaharu wood and promote forest conservation. The objective of this study was to determine the effect of five arbuscular mycorrhizal (AM) fungi: Entrophospora sp., Gigaspora decipiens, Glomus clarum, Glomus sp. ZEA, and Glomus sp. ACA, on the early growth of Aquilaria malaccensis and A. crasna under greenhouse conditions. The seedlings of Aquilaria spp. were inoculated with Entrophospora sp., Gi. decipiens, Glomus clarum, Glomus sp. ZEA, Glomus sp. ACA and uninoculated (control) under greenhouse conditions. Then, percentage AM colonization, plant growth, survival rate and nitrogen (N) and phosphorus (P) content and mycorrhizal dependence (MD) were measured. The percentage AM colonization of A. malaccensis and A. crasna ranged from 83 to 97% and from 63 to 78%, respectively. Colonization by five AM fungi increased plant height, diameter, and shoot and root dry weights. N and P content of the seedlings were also increased by AM colonization. Survival rates were higher in the AM-colonized seedlings at 180 days after transplantation than those in the control seedlings. The MD of Aquilaria species was higher than 55 %. The results suggested that AM fungi can be inoculated`to Aquilaria species under nursery conditions to obtain vigorous seedlings, and the field experiment is underway to clarify the role of AM fungi under field conditions.

The purpose of this study was to formulate effective and efficient institutions of Revolving Fund Loans for Community Forest Plantation development (RFL CFP) in accordance with variation of field conditions. Benchmarking techniques were used to formulate the institution of RFL CFP. For that purpose, Independent of Direct Assistance Rural Agribusiness Development (IDA RAD) from the Ministry of Agriculture was selected as a benchmark as it was good in performance. The study was conducted in three provinces, i.e. Riau, South Kalimantan (November 2008 to April 2009) and West Java (May 2009 to February 2011). Comparative study was used to analyze the institutions based on the agency theory. The results showed that the institutional of RFL CFP have not accomodated the differences in characteristics, perceptions and capacities of the parties. As a result, the institutions have not been able to overcome the risk of moral hazard, adverse selection and high transaction costs. On the other hand, the institution of IDA RADhas a positive impact on agency relationship. High repayments by IDA RADagent and the increasing number of agents each year have proved the impact.

Forests play a vital role for the livelihoods of rural and urban communities. Addressing perception of forest users regarding forest practices is one of the most important aspects of forest management. This paper aims to elaborate stakeholders’ perception on the biophysical, socio-economic and institutional aspects of forest landscape management in upstream Ciliwung watershed. Data were collected through survey, by highlighting preferences, perceptions, and expectations of actors who are interested in the impacts of watershed management. This study indicates that communities at upstream Ciliwung watershed area perceived that the socio-economic aspect is the most important factor in managing upstream Ciliwung watershed. The governments (central and local), however, pay more attention to the biophysical and institutional aspects. The result of the overall perception analysis shows that institutional aspects need to be addressed first, followed by socio-economic aspects and biophysical aspects to improve the management of upstream Ciliwung watershed. Addressing institutional aspects is needed to enhance awareness and coordination among stakeholders, to enforce law and to develop a monitoring system to support the preservation of the forest at the upstream watershed areas. In terms of socio-economic aspects, improving community livelihoods is needed through payments for environmental services. Regarding biophysical aspects, afforestation and conservation of soil and water need to be prioritised. Thus, there should be programs that could provide solutions based on the three main aspects to improve the management of the forest resources in the upstream watershed area.

This study was conducted to provide basic information on the treatment of some wood species using a copper bichromated boron (CCB). The specimens were treated with CCB for 2 hours in a 150 psi of full cell process. The treated and untreated wood samples were tested against marine borers for 4, 8 and 12 months. The results indicated that full cell process with CCB were able to prevent marine borers attack. Untreated wood specimens were susceptible to marine borers attack, except Iara (Metrosiderospetiolata Kds.) and kandole (Diploknema oligomera HJ.L.). The attacking borers are Martesia striata Linn of the Pholadidae family, Teredo bartschi Clapp., Dicyathifer manni Wright and Bankia cieba Clench. of the Teredinidae family. However, crustaceans were found clinging to the wood specimens when they were taken from the sea. These crustaceans belongs to Sphaeromatidae family.

Kekabu wood (Bombax ceiba L.), which is locally known as kapok or randu has long been planted as crops troughout the country, as fiber producer aimed for stuffing pillow. This species is considered as a giant tree which could produce a large quantity of timber. Unfortunately, the timber is too soft, having low density and several physical defects during drying, limiting its uses in conventional wood processing. Any treatment which could significantly increase its structural density may be useful for diversifying the uses of this timber. This study examined some anatomical changes that may exist during mechanical densification. Wood samples measuring 40 mm thick, 40 mm wide and 500 mm long were steamed at 126°C for 30 minutes prior to pressing of 23.75 kg/cm'. Anatomical measures were undertaken using light microscope and scanning electron microscope on both treated and untreated samples. Results showed that the treatment significantly reduced void volume and ray distance of approximately a half the initial wood structure, followed by an increased in wood density of more than 50%.

A 27 year old clonal seed orchard of teak (Tectona grandis L.f ) in Padangan, East Java comprising 24 clones, was evaluated for fertility, offspring diversity, and genetic drift. Flower and fruit productions were used to assess clone fertility in the orchard. Fertility variation measured as ‘sibling coefficient’ was found to be 1,62, having high genetic diversity (0,97) and low coancestry (0,03). The clones varied in fertility in which, 25 % of the most fertile clones in the orchard contributed to 47,5 % of flower and fruit yields. Effective population size in the orchard was 15, indicating that 15 of the clones contributed effectively to seed yield. Separating on the amounts of seeds that can be collected, individual collection, and proportional mixing of seed per clone might be useful in restricting over representation of highly reproductive clones thereby increasing genetic diversity in the seed crop. Another way to improve seed yield in the orchard is by increasing the effective population size. Thinning or prunning on highly reproductive clones might be useful in increasing effective population size.

The welfare level of farmer in rural Sumbawa was steadily low although the potency of natural resources at their vicinity was high. This paper determines the consumption behaviour as well as the welfare level a farmer households in rural Sumbawa, Indonesia. The household size, years of education, and farming incomes were used as indicators of on-farm performance. This research was carried out in February until April 2015 at two separate forest areas which were administratively under Labuhan Badas village, i.e. community forestry (HKm) in the state production forest and private owned forests (POF). A number of 34 respondents perlocation were purposively selected. The multiple linear regression was implemented to analyze factors affecting farmer household consumption behaviour, while the exchange value for income earned by farmer (EVIF) was incorporated to measure the welfare level. The regression revealed that the consumption behaviour at two groups of respondents were positively related with three indicators, i.e. household size, years of education, and farming incomes. Meanwhile, the household size affected the consumption behaviour of the HKm farmers but not the POF farmers. Furthermore, the consumption is strongly affected by the income generated from both forest areas. The EVIF approach revealed that the welfare of whole farmers were still low (EVIF = 0.74-0.99). The government, therefore, should subsidize rain fed paddy and tobacco seeds varieties which are suitable with the local climate, while the farmers are trained to process the flesh of cashew fruit into wine or chips and encouraged to cultivate calliandra trees for apiculture development and wood pellet or charcoal production.

Management of forest is believed that many basic knowledges about the nature of the forest is needed. One of them is to develop the forest as a resource of cane industry in a sustainable way. For this purpose, the composition, distribution and density of rattan species in Gunung Halimun National Park (INGH) were studied as a model. Data were collected from December 1994 until May 1995. For species composition on rattan in TNGH, three areas were observed namely in Mt. Kancana, Mt. Pameungpeuk and Mt. Pangkulahan using a continues belt transect method, from the elevation of 800-1,400 m above sea level. It was found that there were 13 species of rattans in the region. In terms of species richness and densities, Mt. Pameungpeuk comes first, followed by Mt. Pangku1ahan and Mt. Kancana. Calamus beteroides, C.javensis, Daemonorops melanocbaetes, and Plectocomia elongata are dominant both in seedling and nature forms. The nature rattans are relatively abundant in areas less than 1,000 meter above sea level and decrease in number of species as well as the minimal population in the higher altitude. Calamus ornatus grows well at 800-1,400 m asl, while Daemonorops ruber at 800-1,500 m asl, D.oblonga at 800-1,400 m asl.
