Abstract

Abstract: The research aimed to determine parameters affecting household income diversity of farmer’s tribes in South Sumatra tidal wetland, especially studied from the aspect of land acreage, education level, age of farmers and tribes of farmers. The research was using survey method and carried out from June-August 2016 in the Delta Telang I Banyuasin, South Sumatra. The data were recorded by questionnaire for 145 respondents of farmers. Data was processed, described and correlated to see the relevance of the parameters with other parameters. The research concluded that the character of household economy of farmers explaining the relation between production decisions to increase rice production is land acreage, education, age, experience of farmers, number of household members, and labor allocation. Multi commodities farming (rice and plantation) was very favorable compared to monoculture rice fields? But this is a little bit contradictive with government policy that the research area is pointed out as the center of rice production. Therefore, government policy needs to motivate farmers that they can manage their farming from upstream to downstream and they work full in their own farming. The government policy should be site-specific and appropriated with the tribes of farmersKeywords: Household, income, diversity, tribes, tidal wetlandAbstrak (Indonesian): Penelitian ini bertujuan untuk menentukan parameter yang mempengaruhi keragaman pendapatan rumah tangga suku petani di lahan pasang surut Sumatera Selatan, terutama dari aspek luas lahan, tingkat pendidikan, usia dan suku petani. Metode penelitian adalah survey lapangan yang dilakukan pada bulan Juni-Agustus 2016 di Delta Telang I Banyuasin. Data direkam dengan kuesioner untuk 145 responden. Data diproses, dijelaskan dan dibuat korelasi untuk melihat hubungan parameter satu dengan parameter lainnya. Hasil penelitian menyimpulkan bahwa ekonomi rumah tangga petani menentukan keputusan untuk berproduksi. Produksi padi ditentukan oleh luas lahan, pendidikan, usia, pengalaman petani, jumlah anggota rumah tangga, dan alokasi tenaga kerja.  Pertanian multicropping (padi dan perkebunan) sangat menguntungkan dibandingkan dengan monokultur padi, akan tetapi hal ini sedikit bertentangan dengan kebijakan pemerintah bahwa daerah penelitian telah ditetapkan sebagai sentra produksi padi. Oleh karena itu, perlu kebijakan pemerintah untuk memotivasi petani untuk tetap monokultur padi, tetapi petani harus mengelola pertaniannya mulai dari hulu sampai ke hilir. Kebijakan pemerintah ini harus bersifat spesifik dan disesuaikan dengan suku-suku petani.Kata kunci: Rumah tangga, pendapatan, keanekaragaman, suku, pasang surut

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. Bahan amelioran mampu meminimalkan masalah-masalah aktual tanah gambut yang terkait dengan keasaman tanah.Kata kunci: Mengelola, masalah aktual, tanah gambut, keasaman

Abstract

The research aimed to analyze selected properties of peat degradation on different land uses and the sustainable management. The research area is located in the lowland dome peats in the catchment basin of Sibumbung River and Sibotak River in Sub District of East Pedamaran, OKI South Sumatra. The research method used an experimental design of Randomized Completely Block Design with two Blocks and five treatments (Site A: intercropping between oil palm and pineapples; Site B: oil palm plantations, Site C: peat forest; Site D: swamp bush; Site E: swamp grass). The research resulted that drainage and land uses decrease some properties of peats, namely C/N ratio, total pore space, fiber and ash content as well as organic C on cultivated peats and are significantly different at level of 5% compared with uncultivated peats. Bulk density increased due to peat compaction and groundwater table on cultivated peats, which is getting deeper, and significantly different compared with uncultivated peats. All soil series do not show any change because of drainage and different land uses. Sustainable peat management can be implemented through three approaches, namely managements of water, soil and crops.
