Abstract

Kawah Ratu is one of the tourist attractions in the highlands of the Mount Salak Forest, Mount Halimun Salak National Park, Pasir Reungit Village, Bogor. Existing tourism activities can have a positive and negative impact on the surrounding environment. To reduce the negative impact that was usually caused by visitors, it takes activities that can balance the activities of traveling and protecting the environment, namely the interpretation of nature. The purpose of this research was to identify the existing Kawah Ratu climbing trail to be developed as an interpretation trail and to make an interpretation program for the Kawah Ratu hiking trail. The research method was descriptive analysis, by analyzing primary data using Quantum 2.1 software and overlaying with Mount Bunder maps taken from Google earth to produced interpretation trail. The results of the Interpretation trail of the Kawah Ratu trail were Pine and Rasamala Forests, Medicinal Plants, Mushroom Habitats, Flowering Plants, Orchid Plants, Cangkuang Plants, Cigamea and Amphibious Rivers, Fern Plants, Mountain Forests (Montana) and Kawah Ratu. The trail of interpretation of the Kawah Ratu climb that was made has a length of about 3.7 Km with a normal travel time of around ± 1 hour 20 minutes of travel. Some alternative interpretation programs compiled were one-day travel packages, Frog and Toad Kawah Ratu, and Metallic Battle on wide screen. Keywords:Mount Halimun Salak National Park, interpretation trail, interpretation pragramme

Abstract

The Cogreg Experimental Garden planted with fast growing teak has been cut down at the age of 5 years. After being cut down, the stump is maintained so that it grows trubusan. To see plant growth the dimensions of the tree need to be measured in the form of diameter and height of the tree. The data can also be used to measure how much plant growth occurs. The initial assumption of trubusan growth can be influenced by differences in the number of branches growing in the trubusan. Therefore the samples in the calculation of increment in this study were distinguished by the number of trubusan branches growing, namely: 1, 2 and 3 branches. The measurement results obtained data on trubusan growth as follows: 1 branch diameter = 2.915 cm / th, branch 2 = 2.625 cm / th and branch 3 = 2.785 cm / th. Height at branch 1 = 2.1975 m / th, branch 2 = 2.11 m / th and branch 3 = 2.215 m / th. Volume on branch 1 = 0.0275 m3 / th, branch 2 = 0.02 m3 / th and branch 3 = 0.025 m3 / th. From the data obtained, it will be seen the relationship between volume increment and the number of branches that grow on teak trubusan. Data is processed using a simple correlation test with a value of r = 0.159. This shows that there is a positive correlation between the number of trubusan branches and teak volume increments, but the correlation is very weak. This study concludes that the volume increment of JUN at the UNB Experimental Garden is not affected by the number of trubusan branches growing. This gives a recommendation that the trubusan branch that grows can be selected for a maximum of 3 branches. Key words: riap, volume, trubusan, branch, JUN

Abstract

The capacity of farmers is one of the causes of the unoptimization of the application of agroforestry system so that it will affect the low performance of the agroforestry system in generating social, economic and ecological benefits for the community. This study aims to determine the level of farmer capacity in the application of agroforestry system. Data collected using the instrument: (a) Observation (observation), (b) Structured and free interviews. The research variables are managerial capacity, technical capacity and social capacity. The result of the research shows the level of farmer capacity in high category, but the farmer is weak in establishing external cooperation with outsiders to support their farming activities such as traders, input production providers, formal financial institutions / banking, and other information and innovation institution. Recommendations for increased farmers 'capacity through: participatory training and counseling, improving the quality of assisting roles and researchers in empowerment processes, improving farmers' access to capital inputs and markets so that farmers are not dependent on middlemen, and improving coordination between government agencies and stakeholders Keywords: Behaviors, Private Forest, Dangiang Village, supporting and inhibiting factors, SWOT Analysist

Abstract

Management of private forest is influenced by cultural habits and local knowledge. It can be influencing the management of forest, especially for its performance. So that, the utilities of forest resources is expected to provide its productivity, sustainability,  and efficiency. This aim of this study was to measure the level of performance in private forest management in Selepuro Village, Batuwarno Subdistrict, Wonogiri Regency, Central Java Province. This study used a survey method. The data were conducted by interviewed using a structured questionnaire to respondents. The data were analyzed using descriptive analysis. The results showed that the level of performance of private forest in Selopuro Village was high. The private forest performance is shown by high levels of private forest productivity, sustainability of private forest management, benefits of rules in the management and efficiency of private forest cost management. Therefore a high private forest performance will encourage forest management to be better. Keywords: Performance, Private Forest, Private Forest Management

Abstract

Eucalyptus urophylla S.T. Blake in Indonesia is known as Eucalyptus, Popo, Ampupu and in abroad known as Timor white gum and Timor mountain gum. This species is native to Indonesia whose natural distribution includes Adonara, Alor, Flores, Lembata, Pantar, Timor, Wetar and Lombok. In Indonesia this species is recommended for Industrial Plantation Forests (IPF). In IPF activities, thinning is one of the important stages of activities to be carried out. The purpose of this study is to present technical information about the chemical components of thinning Eucalyptus plants which are around 4 years old in relation to their possible use. The results of this study showed that the extractive content of Eucalyptus wood dissolved in cold water, hot water, 1% NaOH and alcohol-benzene were 10.14%, 15.66%, 24.34% and 3.81% respectively. The content of lignin, hemicellulose, cellulose and holocellulose were 22.53%, 26.86%, 56.97% and 83.83% respectively. The difference in the position of the stem influences its extractive content where the higher position of thestem the lower the extractive content. This species is very suitable for pulping materials, both mechanical pulp, semi-chemical pulp and chemical pulp. In pulp and paper making, it is expected that this species would  save the use of cooking chemicals or bleaching materials, resulting in high pulp yields and creating a good bond between fibers in the pulp or paper sheet. In the manufacture of particle boards, it is expected that this species would not become problems in resin hardening, internal breakage of the board due to volatile extractive internal gas pressure or dimensional stability. But this species is not suitable for cement boards. Keywords : Eucalyptus urophylla, Eucalyptus, Thining activity, IPF, Wood chemical component

Abstract

Rawa Danau Nature Reserve is an area of the old volcanic caldera located in Serang District, Banten Province about 100 km to the west of Jakarta. This area has been identified as a very important natural site on the island of Java. This is based on the fact that the main wetland ecosystem at Rawa Danau is the only remaining freshwater swamp forest ecosystem of peat swamp forests in Java Island. The objective of this study was to identify land cover classes and their changes in Rawa Danau Nature reserve area on 2006, 2011, and 2016, and also calculate degradation rate and reforestation during the time of observation. This study was conducted in April - June 2017. Data sources was generated from landat image  ETM+7 coverage year of 2006 and 2011, Image Landsat OLI 8 coverage year 2016 and other supporting digital maps. Supporting tools and instruments used were software, ArcGis 10.1, Erdas 9.1, GPS, Camera and Stationary. The result showed that land cover can be successfully classified both digitally or visually and  composed of secondary swamp forest, marsh bushes, fields, settlements, water body and swamp. Highest degradation during 2006-2016 occured on swamp forest that was converted into fields, while highest reforestation happened on fields that became swamp area.  Key words: Degradation, Image Landsat, Land Cover Changes, Land Cover
