The aim of this research is to assess the correlation of morphological characteristics of nyamplung seedling (Calophyllum inophyllum L) on field growth of two years age after outplanting in Parungpanjang, Bogor. Three seedlots collected from Carita, Pangandaran and Purworejo were grown in seedbeds with different ages (four months and six months). The seedlings are mixed and grouped according to their height and root collar diameter. Each group of seedlings is divided into 5 height classes and each class is divided into two diameter classes, so there are 10 classes of seed morphology. The parameters of seedling were observed on sturdirness quotient, dry weight, root length, shoot-root ratio, and number of leaves. The seedlings were planted in randomized completely block design (three seeds origins, 10 morphological class, three blocks, 30 seedlings per block). Seedling survival, height, and root collar diameter growth were assessed on two years after outplanting. The result showed that morphological classification affected on seedling survival, height and root collar diameter growth. Seedling height and root collar diameter were significantly correlated with other parameters and also with field growth. Two-year-old Nyamplung on field can grow significantly if we use seedling with a height above 31 cm and a diameter more than 5.1 mm. In addition, the ratio of height and diameter and seed quality index are become important consideration in seed selection.Keywords: Calophyllum inophyllum, diameter, height, morphology, seedling quality

Buffer zone management is an integrated practice of managing forest and agriculture land based on biophysical nature of region and social-culture combination to obtain an optimum forest and agriculture products that support local livelihood economy. The study was to identify the community land use patterns that shapes the buffer zone of Aketajawe Lolobata National Park particularly at Aketajawe block. Sampling villages were determined by stratification based on the distance from the National Park boundary which varied between <3,3-5, and > 5 km. The purposive random sampling was chosen 82 respondents to be interviewed. Land use pattern which applied by communities were divided into six groups according to cultivated commodities i.e. community forest, mixed garden, monoculture garden, intercropping garden, horticulture and rice fields. The differences of these patterns were influenced by background and origin of communities. The indigenous people of Halmahera island used their land as mixed garden while the settler used theirs as rice field and horticulture. Based on the land cover quality, mixed garden pattern was more similar to forest vegetation than another pattern. Rice field pattern gave the largest economic contribution while community forest gave the lowest contribution to the farmer’s income.

The availability of topsoil which is relatively fertile to use as seedling media is more and more limited so that the low nutrient degraded soil become alternative media for tree seedling nursery. The purpose of the research was to get the combination of degraded soil media mixture for nyawai (Ficus variegata) seedling media in nursery. The degraded soil collected in the heavy eroded soil in Rumpin Villages, Rumpin Sub District, Bogor. Completed random design with factorial was used to test the media mixture treatments and NPK fertilizer dosages on the growth of nyawai seedling. A pair of leaves seedlings was transplanted on 5 media treatments, i.e. top soil, degraded soil, degraded soil 70 % + compost 30 % (v:v), degraded soil 90 % + rice husk charcoal 10 % (v:v), and degraded soil 60 % + compost 30 % + rice husk charcoal 10 % (v/v). The dosage of NPK fertilizer was used as much: 0 g, 0.5 g polybag, and 1.0 g/polybag. The result showed that interaction of media and NPK fertilizer dosages was only affected on seedling biomass parameter. The interaction treatment of the mixture media of degraded soil 60 %, compost 30 % and rice husk charcoal 10 % could increase the growth of nyawai seedlings high by 30.60 % and fertilizer treatment of 1 g NPK could increase seedling biomass 6.21 g. The mixture media and fertilizing treatment by NPK 1 g can be alternative media on nyawai nursery.Keywords: Ficus variegata, soil media, seedlings, growth

One form of disaster mitigation is to know the vulnerability of areas that are at risk of disaster socially and economically. Studies on vulnerability to flash floods are necessary, as it might prevent material losses and fatalities. Wasior District at Teluk Wondama Regency experienced a flash flood in 2010 causing negative impacts such as fatalities and large material losses. To anticipate flash floods that might occur in the future, studies to evaluate the vulnerability to the flash flood are needed. This study aimed to: 1) analyze the level of vulnerability to flash floods in Wasior based on socioeconomic factors post the 2010 flash floods, 2) analyze the level of vulnerability to flash floods in Wasior based on institutional factors. The method used in this study was a combination of qualitative and quantitative methods. Data collection was conducted by observation, interview, and documentation. Data were analyzed by: 1) identifying the socioeconomic indicators of the community and institutions around the watershed, 2) providing weighting scores to the social economic criteria and institutional criteria from the most vulnerable to the least vulnerable, 3) assessing the level of community and institution vulnerabilities in the study site to the impact of flash floods based on the calculation of the weighting scores of socio-economic and institutional indicators. The results showed that the level of socioeconomic vulnerability to flash floods were categorized as moderate (total score 2.084), while the level of institutional vulnerability was low (total score 2.251). The results of this study can be used as a basis for considerations in the implementation of flash flood mitigation in Wasior.Keywords: vulnerabilities, social, economic, institutional, flash flood
