Abstract

Abstract: The research objective is to manage actual problems of peatsoils associated with soil acidity. The research has been conducted on peatsoils in river backswamps located in Subdistricts of East Pedamaran and Pedamaran, District of OKI South Sumatra. Soil sampling was taken in cultivated and uncultivated types of landuse; cultivated peatsoils consist of Site A (intercropping between oil palm and pineapple) and Site B (oil palm), uncultivated peatsoils are divided into Site C (peat forest), Site D (swamp bush) and Site E (swamp grass). The research resulted that actual problems of soil acidity is associated with base saturation, cations exchange capacity, soil organic matters and C/N ratio, balances of soil nutrients, and toxicity potency. The climatic condition and drought can accelerate the occurrence of actual problems of peatsoils associated with acidity peatsoils. Some ameliorant have been applied in order of importance in the fields, namely lime/dolomite, mineral soils, organic fertilizers, combustion ash, and volcanic ash. Application of ameliorant materials is capable to minimize the actual problems of peatsoils associated with soil acidity.Keywords: Managing, actual problems, peatsoils, acidityAbstrak (Indonesian): Tujuan penelitian ini adalah untuk mengelola masalah aktual tanah gambut yang terkait dengan keasaman tanah. Penelitian ini telah dilakukan pada tanah lebak gambut yang terletak di Kecamatan Pedamaran Timur dan Pedamaran, Kabupaten OKI Sumatera Selatan.  Contoh tanah diambil berdasarkan jenis penggunaan lahan; untuk tanah gambut yang digarap dibagi menjadi Site A (tumpang sari antara kelapa sawit dan nanas) dan Site B (kelapa sawit), tanah gambut tidak digarap dibagi menjadi Site C (hutan gambut), Site D (rawa semak) dan Situs E (rumput rawa). Hasil penelitian menunjukkan bahwa masalah aktual keasaman tanah dikaitkan dengan kejenuhan basa, kapasitas kation tukar, bahan organik tanah dan C/N rasio, keseimbangan nutrisi tanah, dan potensi toksisitas. Kondisi iklim dan kekeringan dapat mempercepat terjadinya masalah aktual tanah gambut yang terkait dengan keasaman tanah.  Amelioran yang telah diterapkan, yaitu kapur/dolomit, tanah mineral, pupuk organik, abu pembakaran, dan abu vulkanik.

Abstract

The research aimed to analyze the functions of lebak swamp before and after landfills and to seek some alternative management approaches in Jakabaring South Sumatra. The research used quantitative and qualitative approaches. The research area description was assisted with interpretation of landsat images. The research was using survey method and interviews with local people. Two major functions of lebak swamp are ecological functions and non-ecological functions. Before landfills (1988), ecological function of lebak swamp was very dominant (91.64%) and non-ecological functions was about 8.36% meaning that the human intervention was only 8.36%, so lebak swamp has very high resilience capability to recover its ecosystem. After landfills (2016), that ecological functions are reduced becoming 53.88% and non-ecological functions increased to 46.12%.  The region is still save enough for office and housing because the ecological functions (greening areas) occupy an area of more > 30%. In 2030, ecological functions will decrease about 15.53%, while the non-ecological functions will increase around 84.47%. Although in 2016 Jakabaring is still environmentally safe, if we analyze more deeply and intensively, Jakabaring will be vulnerable to man-made disasters such as potential of floods and droughts, sedimentation, migration and dependency on other local staple food.Keywords: Functions, lebak swamp, landfills, Jakabaring, South Sumatray

Abstract

This research aimed to analyze potential supply and removal of biomass and soil nutrients induced by different vegetation on peatlands. The research was carried out in peats dome of the catchment area of the Sibumbung River and the Burnai River in Pedamaran Sub-Districts, OKI South Sumatra. The research method used field survey of case studies of four natural phenomena (swamp grass, bush swamp, pulai peatlands, and peat forest). The research resulted that the highest production and harvest of biomass came from peat forest, pulai peatland, bush swamp and swamp grass. The highest biomass supply to the soils were given by the peat forest, pulai peatland, bush swamp and swamp grass (around 12,545; 11,593; 7,491 and 5,313 kg/ha/year respectively). The more varied the vegetation type, the higher the supply of soil nutrients. Swamp grass and bush swamp have low vegetation diversity and are mostly dominated by alang-alang. Swamp grass and bush swamp showed the same pattern and the order of nutrient supply in the highest sequence is K, Ca, N, Mg, Ca, and P. The supply order of soil nutrients (peat forest and pulai peatland) showed a similar pattern, namely from the highest content of Ca, N, K, Mg and P. Pulai vegetation can be recommended for a paludiculture system because it resembles almost the peat forest in producing biomass and soil nutrient supply to the soils and is originally native plant from peatland.

Abstract

Investment development for oil palm plantation in Indonesia was increasing and it clear away into peat land area. Land clearing activities without considering peat ecological function may have impact on environmental degradation. The objective of this research was to study development potential of oil palm plantation at peat land by using land evaluation approach. The field survey method was observation scale and land suitability assessment was based on FAO standard with adjustment. Assessment results showed that land had peat thickness higher than 3 m covering 28% of total area so that it can be opened for oil palm plantation. The main constraint factors for the clearing of feasible area were soil reaction, flooding condition and nutrients status. These parameters could be potentially improved. However, final assessment of land showed that it was classified as less feasible (S2) due to relatively high investment.  Cultivation can only be conducted with provision of drainage facility. Caution should be taken in designing open channel in order to prevent excessive water drainage. Therefore, hydrologic analysis can be based on 5 years return period only. Computer simulation of DRAINMOD was applied to determine the operational effect of control structures in elevating of water table during dry season. Simulation results showed that during the opening operation of open channel without control structures at dry season, water table was dropped up to 90 cm below soil surface. Water retention effort in tertiary channel at 70 cm level could elevated water up to 30-40 cm below soil surface. The key success for oil palm plantation development at peat land was highly depended on availability of control structure at tertiary channel. Flap water gate type from fibre material was very suitable for field application. Retention system by using soil sack or stoplog water gate could be implemented at initial stage in order to economize the cost.
