Amelioration is very important in supporting plant growth in peat land. The use of low emission ameliorant will support the sustainability of agricultural system in peat land. The research is intended to study the effectiveness of some ameliorants in reducing CO 2 and N 2 O emission in corn planting in peat land. The research was conducted in April to October 2013, in Kalampangan Village Palangkaraya Municipality Central Kalimantan. Ameliorant materials used were chicken manure fertilizer, domolite, mineral soil, paddy husk biochar, coconut shell biochar. Ameliorant treatments applied were the type of ameliorant compositions, those were (A1) 80% chicken manure fertilizer + 20% dolomite, (A2) 20% chicken manure fertilizer + 20% agricultural weeds + 20% spodosol mineral soil + 20% “purun tikus” ( eleocharis dulcis ) compost + 20% dolomite, (A3) 19% chicken manure fertilizer + 9% dolomite + 72% mineral soil, (A4) 100% coconut shell biochar, (A5) paddy husk biochar, (A6) farmer’s way (20% ash + 40% spodosol mineral soil + 40% chicken manure fertilizer) and control. Experiment design used a Randomized Factorial Block Design, with 3 repetitions. Ameliorant dosage used was 7.5 t/ha. The crop used was hybrid corn. Parameters which were observed periodically were emission of CO 2 and N 2 O, ground water level height, soil pH and Eh, once a month for 5 periods. The research result showed that ameliorant was capable of reducing emission of both CO 2 and N 2 O in corn planting in peat land. Coconut shell biochar could reduce emission of CO 2 up to 26% as compared with control, whereas paddy husk biochar could reduce emission of N 2 O up to 52% as compared with control.

The research aims were to get the indigenus endophytic microbial consortium and to test the potency of kalakai leaf extract as biopesticides and biofertilizer on chili plant specific to wetlands (i.e., var. Hiyung). The microbes capable of inhibiting the growth of anthracnose have been performed on in-vitro test in pairs method. It was found that 12 isolates have the ability to inhibit the growth of pathogens. However, based on the results of a confirmatory endophytic test only three isolates had positive role as endophytic in chili plants, namely Trichoderma sp DN3, Trichoderma sp AK2, and Trichoderma sp BT1. The results of the effectiveness of each treatment on chilli plants in the greenhouse and the field shows that the application of endophytic could inhibit the development of anthracnose and spur the growth of plants. It could be concluded that the applications of kalakai leaf extract at the rate of 30 mL/plant can function as biopesticides and biofertilizer.

This research aimed to analyze land degradation by using landscape balances in lebak swamp Jakabaring South Sumatra. The study was carried out in Jakabaring, South of Palembang. Field survey method was applied, the field observations and respondents were taken by randomly purposive sampling. The interviews with farmers were done by using open questionnaire. The study resulted that erosion and abrasion rises above 1,000 % which includes the acreage of 1.16 % in 1988 to 12.34 % in 2015. The landscape becomes more dynamic from year to year (namely 88.75 % of normal landscape in 1988 and becoming 68.14 % in 2015). The drought in the lebak swamp is increasingly unpredictable, making it difficult for farmers to manage their farming activities. Deposited landscape was found about 272.43 ha (10.09 %) in 1988 and increased to approximately 527.04 ha (19.52 %) in 2015. Lebak swamp serves a lot of coming water from the upstream catchment area of approximately 3 million ha. This service is more and more complicated, irregular and burden lebak swamps. The lebak swamp ecosystem has not only enormous potential, but also has a very high resilience.

The research aimed to formulate an investment decision for oil palm plantation in tidal wetlands of PulauRimau, Banyuasin South Sumatra Indonesia. The research summarized that Land productivity and input amount will determine some differences of each soil suitability (S 1 , S 2 and S 3 ). The more land suitability level is, the more Fresh Fruit Bunches of Oil Palm (FFB) productivity per ha is produced and the less input is given. Net B/C Ratio, NPV and IRR for all land suitability classes are financially feasible for oil palm plantation development, however the most feasible and the most Expected Rate of Return (IRR) is in tidal wetlands with S 1 land suitability (very suitable), followed by S 2 (suitable) and S 3 (marginally suitable). Sensitivity analysis to feasibility for three land suitability is still economically feasible to build and to develop oil palm plantation, especially in large scale, thus its decision for capital investment is suitable.

Until now the raw material of wood especially Gelam ( Melaleuca cajuputi ) available for supporting the construction of housing and other infrastructures is increasingly large in Indonesia. On the Island of Borneo that partly consists of swamps needs Gelam very large and continuous, particularly for residential development. However, areas of peat swamp forest habitat of this plant from year to year are degradation and shrinkage. This situation is a very big influence on the population of Gelam, while the management and timber trade systems are not well regulated. This study aims to analyze the management and timber trade systems of Gelam particularly in South Kalimantan to provide input to the policy holder in the preservation of Gelam. The method was used a field survey and interviews with traders and policy holders related regulations. The results showed in South Kalimantan the potency of Gelam is only 2,9-7,1 m3/ha and decreasing yearly. Normally Gelam with a diameter 30 cm. These dimensions should not be cut because of 30 cm can be used as seed sources. Gelam derived from peat swamp forest, which mostly comes from the Batola District and some came from Kapuas District of Central Kalimantan. Distributions of Gelam were starting gatherers logging in the forest then sold to small gatherers, next to the large gatherers and distributed to all districts/cities in South Kalimantan, wood processing industries, and some of them were sent to Java. The silviculture system of Gelam was using selective cutting. Classification of wood sizes traded by the diameter divided into 3-4cm, 5-6cm, 7-8cm, 9-10cm, 11-12cm, 13-14cm, 15-19cm and > 20cm to 4m long. Its use consists of a small diameter (3-10cm) for foundry building and firewood, while the large diameter (10-20cm) for the construction of houses in swampy areas, and waste as well as the stems are bent and deformed used for firewood. Until now Gelam becomes into the business community and potential sources of local government revenue if managed properly. However, due to the rules of management and administration in South Kalimantan was not going well, thus threatening the sustainability especially with the growing extent of peat lands being converted into palm oil plantations.

Carbon stock in peat soils is very high, it is necessary to prudent in its management because peat soils is emitting greenhouse gases such as CO 2 during land clearing due to oxidation of peat layer. This research was conducted to study soil carbon stock stratification in relation to soil physical and chemical properties. The carbon stock stratification was based on maturity degrees of peat. The study was conducted in Pulau Damar Village, Hulu Sungai Utara District, South Kalimantan Province on land use rubber. The location of the study area was determined by using the purposive sampling method. All data obtained were analyzed by Excel spreadsheets and drawn on a CorelDraw 12. The results showed that the amount of carbon stock was influenced by the maturity degrees of peats, peat sapric degres has higher carbon stock than of hemik and fibric with a ratio of 2.0: 1.5: 1. The relationship between soil carbon stock with soil physic (Bulk Density, BD) and chemical properties (pH, Eh, Fe, and total-N) were not significantly.
泥炭土的碳储量非常高，由于泥炭层的氧化，在土地清理过程中，泥炭土会排放二氧化碳等温室气体，因此必须谨慎管理。本研究旨在研究土壤碳储量分层与土壤理化性质的关系。碳储量分层以泥炭的成熟度为依据。该研究是在南加里曼丹省Hulu Sungai Utara区Pulau Damar村进行的，关于土地利用橡胶。采用目的抽样法确定研究区域的位置。所有获得的数据通过Excel电子表格进行分析，并绘制在CorelDraw 12上。结果表明:泥炭的碳储量受泥炭成熟度的影响，泥炭的含盐量高于半麻和纤维，两者的比例为2.0:1.5:1;土壤碳储量与土壤物理(容重，BD)和化学性质(pH, Eh, Fe和全氮)之间的关系不显著。
