Abstract

ABSTRACTThe land in the Kalampangan sub-district of Sabangau District is land that is dominated by peat soils.Peat binds to a relatively large amount of carbon that is formed in a long process and under watersaturated conditions. Water-saturated conditions cause the weathering process of organic matter to beimperfect, so that the remains of organic matter such as litter, roots. The land in the KalampanganVillage is a wetland with a layer of peat composed of organic material with a high C content thatexceeds carbon content in the terrestrial ecosystem. The aim of the study is to analyze the perceptionsof vegetable farmers towards the development of sustainable peatland agriculture. The studypopulation was all 164 vegetable farmers, the sample size was carried out by the Slovin techniqueaccording to Sugiyono (2011) with a total sample of 35 people. Analysis of the data used in the formof qualitative data and quantitative data. Sourced from primary data and secondary data. Using aLikert scale which is translated into sub-variables then sub-variables are translated again intomeasured indicators. The results of the research and analysis conducted on peatland vegetable farmers'perceptions of the development of sustainable agriculture in the Village of Kalampangan are "agreed".This perception is shown by the acquisition of a percentage score of 60%. Obtaining the percentage ofperception score of vegetable farmers for each sub-variable used is in the good or agreed category.Keywords: Perception, Development, Peatlands, Sustainable Agriculture

Abstract

ABSTRACTThis study aims to determine the effect of the location distance from the river bank and the depth ofsoil layer to the soil chemical properties in the tidal land area. The study was conducted in April untilJune 2016 in the tidal areas of Bajarum village, District of Kota Besi, East Kotawaringin, CentralBorneo Province. The study used survey methods and soil sampling in the field, analysis of soilsamples in the laboratory and continued with analysis and description of data. Soil sampling wasconducted at distances of 250, 500, 750, 1.000, 1.250 and 1.500 meters from the Mentaya river bankat two depth soil layers (0 - 25 cm and 25 - 50 cm). The soil chemistry properties analyzed includedpH, cation exchange capacity (CEC), base saturation, organic C, N total, total P2O5, total K2O,alumunium and hydrogen exchangeable and soil fertility status. The results of study showed that: (1)The further distance of soil from the position of Mentaya river bank there is an increase of organic C,total P2O5, total N, total K2O, pH, CEC, base saturation and soil fertility status, on the contraryshowed a decrease in alumunium and hydrogen exchangeable. The limiting factor of soil fertility ismainly the low base saturation, besides that at some point observation also due to low CEC, totalP2O5 and total K2O. (2) Sub soil layer (25 - 50) cm has a higher pH and base saturation valuescompared to topsoil layer (0 - 25) cm. In contrast, topsoil layer has CEC, alumunium and hydrogenexchangeable, total P2O5, total K2O, total N and organic C values higher than sub soil layer.Keywords: distance from river, tidal soil, soil chemical properties.
