Abstract

ABSTRACTRed-yellow podzolic soil is widespread in West Kotawaringin and mostly used as agricultural land. It causechanges in soil properties so that soil fertility analysis is needed. The research aims to study the chemistry andphysics of red-yellow podzolic, as a result of agricultural activities. The research was conducted by taking soilsamples from unmanaged land (control land) and oil palm plantations belong to KUD Tani Subur which appliedoil palm integration with cows in Pangkalan Lada, Central Kalimantan. In this study we conducted simple randomsampling method with 5 replications. Variables used as parameter in the study are porosity, bulk density, pH, Ctotal, N-total, P-available, Cation Exchange Capasity (CEC), base saturation (BS), Fe, and Al-exchangeable. Theresults show oil palm plantations have soil porosity 51,84%, bulk density 1,28 g cm-3, pH soil about 5,02-5,04;C-total 1,23-1,69%; N- total%; 0,06-0,11%, P-available 8,1-8,9 ppm; CEC 18,52-22,85 me 100g-1; BS 1,79-3,24; Fe 0,59-0,82 ppm; and Al- exchangeable 110,46-111,29 ppm, but control land have soil porosity 45,03%;bulk density 1,46 g cm-3; pH 5,04-5,13; C-total 0,76-1,05; N-total 0,09-0,19; P- available 9,3-9,7 ppm; CEC20,30-22,27 me 100g-1; BS 2,33-2,76%; Fe 0,02-0,68 ppm; and Al-ec 126,67-156,60 ppm. Land use of RYP soiltypes as oil palm plantations with semi- organic processing techniques does not degrade the soil, and couldincrease land productivity compared to unmanaged land.Keywords: RYP, soil chemistry and physics, different land use.

Abstract

ABSTRACTRiparian vegetation is easily distracted natural resource due to mankind activities. This study attempts toexamine the species composition, the stand structure, and the species diversity of riparian vegetation on PagerRiver, Rakumpit district, Palangka Raya. The vegetation data were collected through path combination method withgridline. We find out that the plant diversity of all types of growth is 28 species with 16 families. The number ofspecies on station I (upstream) are 13 species with 7 families, while the species having the highest INP is GalamTikus (Syzygium zeylanicum (L) DC). There are 19 species with 11 families on station II (middle) in which Resak(Vatica rassak) has the highest INP. Meanwhile on station III, there are recorded 16 species with 11 families wherethe most dominating species is Balawan (Tristaniopsis stellata Ridl.). The spread of tree diameter of riparianvegetation on Pager river (upstream, middle, downstream) suggests the pattern of reversed "J". Of the upstreamriparian, the species diversity values of all types of growth sit on the low category. Of the middle and downstreamriparian, the diversity values are both low at the seedling and sapling level.Meanwhile, those values are in mediumcategories at the pole and tree level. The species richness generally corresponds to the low category whereas thespecies evenness corresponds to the high category.Keywords: Diversity index, species composition, structure, riparian vegetation

Abstract

ABSTRACTA study have done by scientists on plant shrews in Kalimantan, as result indicated there were five endemic plantshrews, Dendrogale melanura, Tupaia dorsalis, T. montana, T. picta dan T. splendidula. They appoint to endemicespecially Kalimantan were estimated consequence formed barrier on the era broken Kalimantan from motherterrestrial Asia on Pleocene epoc (estimated two million years ago). Untill now there have been opposite proceedson the plant shrews ancestor, many scientists said they were inherited from Primate order and the others said theywere insectivores, but the recent taxonomy to classify into Scandentia order. The shrews have insectivore andfrugivore characters. Whereas the Bornean nonendemic shrews among other things Tupaia glis, T. minor andPtilicercus lowi, because theyhave been found in outside of Kalimantan area.Keywords: Tree shrews, Endemic, Kalimantan

Abstract

ABSTRACTEstimation of forest stand parameters such as stand density, dominancy and frequency in a large areausing remotely sensed data has considerable significance for sustainable management and utility ofnatural resources. In practice, selecting suitable image data for such purposes remains difficult due to apoor understanding of forest stand parameters and remote-sensing spectral response relationships,particularly in Peat Swamp Forest (PSF) regions. This paper explores relationships between foreststand parameters and Landsat 7 Enhanced Thematic Mapper (ETM+) spectral responses throughForest Canopy Density (FCD) analyses of peat swamp forest in Central Kalimantan Indonesia. SevenETM bands and many biophysical indices are examined through integration of spectral responses andfield vegetation inventory data. Pearson?s correlation coefficients are used to interpret relationshipsbetween forest stand parameters and ETM data through FCD. This study concludes that FCD andstand density, stand dominancy and species frequency are most strongly correlated, and we canestimate standing stock of forest accurately.Keywords: forest canopy density; stand density, dominancy, frequency, peat swamp forest

Abstract

ABSTRACTThe rate of forest degradation and deforestation in Central Kalimantan Province between in 1991 to 2001 ± 3.3% peryears, between in 2000 to 2009 ±0,1% per years, between in 2009 to 2013 ±1,2% per years. These conditions havean impact on decreasing of economic value of upstream forestry sector in Indonesia in 2015 is equal to ± 1.5% ofGross Product Domestic. Gross Regional Domestic Product (GRDP) of Central Kalimantan Province to the commonagricultural sectors (agriculture, fisheries and forestry) in 2016 ± 22.1%. GRDP of common agricultural sector in EastKotawaringin District in 2014 ±23.85% with the contribution of the plantation sector ±19.25%. Low contribution offorestry sector to GRDP, it was supposed that the sector is less promising. This research aims to determineeconomic benefits value of secondary forests and lost value in case of forests conversion into oil palm plantations,rubber plantations and coconut plantations. This research conducted in East Kotawaringin District during ± 6 monthswith observation area covers 7 subdistricts through field survey and secondary data. The results showed that totaleconomic value (TEV) of secondary dry forest with large areas ± 20,800 ha ± Rp 769.4 billion per years, TEV ofsecondary swamp forest with large areas ± 12,900 ha ± Rp 453.6 billion per years, TEV of secondary mangroveforests with large areas ± 2,900 ha ± Rp 83.9 billion per yearsKeywords: Keywords: economic valuation, secondary forest, forest conversion, plantation

Abstract

ABSTRACTActually, commodities that have been developed by communities were potential commodity because the communityhave considered the aspects of technical, economy and social. Nevertheless, some commodities developed by thesecommunities were still not optimal, thus it needs a feasible development model. The results showed that based onland type, local commodities in KHG Kahayan - Sebangau could be developed through three models, namely theintegration model of agro-silva-pastura-fishery on inland peat type, while in transition peat type was integration modelof agro-silva-pastura, and in coastal peat type was integration model of agro-silva-fishery.Keywords: Peat land, local commodities
