Peat soil is one of the decent growing medium for aloe vera plant. Seeing the potential of peat land in West Kalimantan is quite extensive, this plant is cultivated commercially and becomes one of the leading commodity in peatlands in West Kalimantan, especially in Pontianak City with an area of more than 25,000 ha. With complete and varied nutrient content, this plant progress opportunities, especially for diversification is enormous ranging from food products and beverages such as juices, cocktails, aloe vera gel in syrup, jams, jellies, tarts, sweets, tea, chips and as well as agro-tourism in West Kalimantan. Existing obstacles now are market share and unstable price, trouble controlling plant diseases and peat area is flooded during the rainy season. Prospects for the future development of these plants can be carried out through the cooperation of government and relevant stakeholders,stable markets and prices, the acceleration of product promotion through fairs and business gathering activities, as well as the dissemination and application of cultivation technology and post-harvest of aloe vera.

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.

Production of granulated sugar from sap of nipa palms in South Kalimantan Province is a new innovation. The purpose of this study was to find out the chemical compounds contained in granulated sugar made from sap of nipa palms growing in 3 different places, which was expected to benefit wider community as a source of alternative sweetener. The chemical compound test of granulated nipa palm sugar was conducted at the Laboratory of Institute for Research and Standardization of Industry, Banjarbaru. Chemical parameters tested were water, sucrose, reducing sugar, fat, protein, phosphorus, and potassium content. The test results showed that the water content of granulated nipa palm sugar in treatment A 1 , A 2 , and A 3 was 3.69%, 4.04%, and 2.31%, respectively; the protein content 0.65%, 2.19%, and 1.10%; the fat content 0.27 %, 0.34 %, and 0.20 %; the reducing sugar content 2.39%, 0.51%, and 0.52%; the sucrose content 75.14%, 68.15%, and 88.46%; the phosphorus content 1.1342%, 1.1196%, and 1.138%; and the potassium content 1.60%, 1.40%, and 1.58%, respectively. The test parameters of granulated nipa palm sugar that met the Mandatory Indonesia National Standard (SNI) 01-3743-1995 were the water content of granulated sugar from sap of nipa palms growing in dry place (land), the reducing sugar content and sucrose content in all treatments. It can be concluded from the three required parameters that granulated nipa palm sugar is able to become the source of new sweetener in addition to block arenga palm sugar and crystal cane sugar for the community in South Kalimantan.
