Abstract

ABSTRACK Nyaru Menteng arboretum is the genetics resources area that located at the Palangka Raya District, its wide namely 65.2 ha. In this area, there are many flora and fauna, including kelasi (Presbytis rubicunda), a species in danger that protected by law. At the Nyaru Menteng arboretum area, there are also the Re- introduction of Orang Utan Centre that managed by BOS. This research was aimed to know the kelasi population at the Nyaru Menteng arboretum area and to record some herbs and plants to be their foods. The research was conducted at the Nyaru Menteng arboretum area at 2017 using survey method to calculate the population of kelasi number and wide of their habitat. Research result showed that there one kelasi at January 2017 at three kelasi at April 2017 namely kelasi of male, female and young. Analysis result showed that the density of kelasi was 0.06 species ha-1. There is decrement kelasi at 2017 than 2007. Ten years ago, kelasi was detectabled namely 15 species with the density was 0.23 species ha-1. Some herbs and plants which to be food of kelasi i.e. jambuan (Syzgium cerinum), saga (Adenathera microsperma), singkong (Manihot utilisima), karet (Havea brasiliensis), nenas (Ananas comosus), kelakai (Stenochlaena ralustris), buah nangka (Artocarpus integra) and other fruits.

Abstract

ABSTRACK Patterns of community life tend to back to nature including the drugs utilization. They generally use medicinal plants (roots, stems, leaves, flowers, fruits and seeds) without knowing its active chemical compounds and partly morphologically unfamiliar also. This research was conducted to identify the characteristics of medicinal plants (general, environment, habitat and morphology of medicinal plants) through observation in the field and to know the content of active compounds (secondary metabolites) prosfective medicinal plants that be used by the community of Natai Sedawak Village by doing phytochemical testing in laboratory. Data analysis is done descriptively qualitative and quantitative in the form of tabulation and picture. The results of observation showed that the characteristics of medicinal plants in Natai Sedawak village are tree, shrub, herb (terna) and liana, with single and compound leaf composition, cylindrical trunks except tapus and Loranthus sp. They grow in swamp forest with altitude namely 17 to 25 meters above sea level and soil pH between 2.60 to 3.85. Based on the results of phytochemical analysis, medicinal plants contained secondary metabolite compounds that consisting tannin (polifenol), alkaloid, saponin, flavonoids, steroids and terpenoids that scattered in plant organs as at the roots, stems, leaves, and fruit. Keywords : Drug growth, phytochemical analysis, Natai Sedawak Village.

Abstract

ABSTRACK Production forest management in Indonesia had been developed using a pattern of forest concessions (IUPHHK) since 1970s. In the development portion has ended a period of concession for 20 years. Forest areas that are not burdened the forest concessions or other rights, then the management is partly handed back to the goverment, and some management handed over by other appliances as Timber Utilization Permit (IPK). In connection with that carried a 0,3% timber cruising activities in the work areas of PT. ? Kalang Murni to obtain details about the condition of the standing stock. According on the analysis results, the standing stock of commercial trees in the group of diameter ? 20 cm contain average number of 25.5 stems/ha and average volume of 15.69 m3/ha, and the standing stock of other timber in the group of diameter ? 20 cm contain average number of 27.3 m3/ha, and average volume of 20.57 m3/ha. With the result that the total standing stock of the tress at the secondary forest of PT. Kalang Murni contain average number of 52.8 stems/ha and and average volume of 36,26 m3 / ha. According to the financial analysis, the Indonesia Strip Cutting and Planting (TJTI) system is suitable applied at the site when the interest rate in the position of 18%, whereas the Clear Cutting and Artificial Regeneration (THPB) system is not suitable at the same of interest rate.

Abstract

ABSTRACK Logging activities have an impact on changes in composition and standing structure, tree species distribution, community similarity and species diversity. This study was aimed to determine the diversity of structures and composition of trees at the logged-over forests. Area of study was located at annual Block of 2005, 2010, and 2015 of forest concession (IUPHHK-HA) PT Sarpatim in Central Kalimantan Province. Data was collected at 2017. The results showed that the composition and structure of the stands are ecologically different, which is indicated by the low type of species equality index. The stands at the level of seedlings, sapling, poles and trees from each location are almost all different. But there are some of the same types encountered dominating on the block locations of 2005, 2010 and 2015 such as Shorea leprosula, Dipterocarpus borneensis, Shorea laevis, Litsea sp. The stand density at the 2005 block location is higher than the two sites in 2010 and 2015, while the location of 2015 is the location with the lowest stand density. Keywords Composition, density, diversity, standing structure.

Abstract

ABSTRACT Wood of moon (Fagraea crenulata) and wood of mahang (Macaranga sp.) are not included the commercial timber species, therefore the knowledge regarding chemical properties of their woods are needed in order to provide information for various purposes according to their properties. The research was aimed to know chemical properties of moon wood and mahang wood. The research had been conducted at the laboratory of Forestry Department, University of Palangka Raya since February to March 2017. Research resultd showed that the solubility of moon and mahang woods in the cold water, hot water, 1% NaOH and alcohol benzene are classified as high. According chemical components analysis, their wood are not suitable for pul and paper, because they have some characteristic as follow: holoselulosa is poor, cellulose is low, hemicellulose is middle, and lignin is not good. Meanwhile, wood ash of moon and mahang are classified moderate (range of Indonesia chemical components of broadleaf wood is range start from 0.2 to 6%) with values of them are 0.654% for moon wood and 0.689% for mahang wood. With the result their woods are considered to wood energy utilization. Keywords: chemical component, mahang wood, moon wood, wood energy
