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

ABSTRACTThis research proves the variation of Ketapang Wood Physical Characteristics on fresh water content, air drywater content, specific gravity, shrinkage and development due to differences in the location of wood along the stem.The study used a completely randomized design (CRD) with 3 replications. The research standard used DIN as asample taken as many as 3 pieces each part of the stem so that the number of test samples on one tree as many as99 test samples for each treatment. The treatments examined by axial direction of the stem in the section of Base(P), Middle (T), Edge (U) and further tests using the smallest real difference test (BNT). Results of the study Thephysical properties of ketapang wood in general have an average fresh water content (73.04%), air dry water content(47.76%). Maximum density (0.47), Development of dry to maximum kiln conditions (5.94%), development ofmaximum dry air to dry conditions (2.45%). Ratio (T / R) at maximum conditions to air dryness (1.45%) including lowclassification. Ratio (T / R) of maximum conditions to kiln dry (1.56%).Keywords: Fresh water content, air dry water content, specific gravity, shrinkage, development.

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

Abstract

ABSTRACTThis study was conducted to determine the stored carbon stock, types of vegetation in the study sites andthe influence of forest fire. This research used standard method used by group of researchers whose joininginternational network: Alternative to Slash and Brun (ABS) with observation subplot 5 m x 40 m = 200 m2, vegetationbiomass measurements of 5 ? 30 cm and > 30 cm (if any), biomass measurements of lower plants (understory, d < 5cm), measurements of necromass that present at the soil surface. This research was conducted at an ex-firedpeatland area of Tumbang Nusa Village, Cental Kalimantan. The results showed that vegetation biomass based onthe distribution of diameter class of 5 ? 30 cm has a large biomass of 2,607.16 Mg ha-1 because in the 5 ? 30 cmdiameter class the vegetation contained in it was a type of tree that has a large biomass content, whereas thenecromass was low i.e. 44.93 Mg ha-1, because few trees and woody necromass. The carbon stock in the study areawas 1,242.88 Mg ha-1; this figure was small.Keywords: Carbon Stock, biomass, necromass

Abstract

ABSTRACTOpenness of forest land due to timber harvesting is a loss of forest soil surface protection caused by logging,skidding, making forest road network, timber stockpiling, base camp and so forth. The aim of this research is tocalculate the percentage of forest land clearing due to temporary timber harvesting (tree felling, skidding, skid trailconstruction, TPn) and permanent nature (making of main and branch road network). The research was conducted atIUPHHK-HA PT Indexim Utama Central Kalimantan. The results show that the percentage of forest land clearing dueto timber harvesting is much higher (19.54%) than that of permanent (4.55%). Deforestation and main road makingactivities contributed the most to the percentage of temporary and permanent land clearing respectively by 10.66%and 3.94%.Keywords: Temporary and permanent, natural forest, forest land clearance, timber harvesting.

Abstract

ABSTRACTFish drying business from fisherman catch is the simplest and easiest type of business done by fishermenand their families who live in the coastal area. Dried fish has a well-ordered market segment with a continuous scaleof demand in a certain amount. Limitations of the number of requests that can not be increased in a short time andcertain result in high potential malpractice product quality in the process of drying fish. The study aims to prove thatmarket economic pressure is the cause of high risk of malpractice quality of dried fish products.The research method is descriptive phenomenalogis with analytical tool using approach of simple shift sharematrix. The research was conducted around TPI of Gisik Cemandi village of Sidoarjo Regency and Fishery Port ofNusantara in Brondong Village, Lamongan Regency; during January 2017 to March 2018. Observations to describethe phenomenon of potential malpractice begins with terrestris surveys using a closed questionnaire tool with predetermined respondents (purposive sampling) by researchers with local informants. The phenomenal description ofpotential product malpractice quality in shift share matrix was measured by Likert scale 1-10 to obtain a quantitativepicture of the rate of deviation suspected to occur at each observation point.The result of economic observation and analysis shows that the fisherman family of Gisik Cemandi village inSidoarjo does not have the potential of malpractice of dried fish product quality. The value of gap analysis shift shareabout potential malpractice of dry fish product quality> 6,0; with all factors positive. Fish drying business in BrondongVillage of Lamongan Regency is inversely proportional to Sidoarjo. The value of the gap analysis shift share onpotential malpractice of dried fish products <6.0 on 13 factors that trigger fish drying business to use preservativesand hazardous materials in the drying process of fish is very possible.Keywords: dried fish, quality, malpractice, Gisik Cemandi, Brondong, shift share
