Abstract

he research aimed to analyze livelihoods, household income and indigenous technology in South Sumatra wetlands. The research method used field survey and interviews with respondents by using questionnaires. Respondents were determined with stratified random sampling method. The research data are classified into two parts, i.e. primary data and secondary data. The research showed that three main farmer’s groups settling in wetlands are spontaneous migration (Buginese and Banjarnese), new comers (transmigration) and indigenous people (local people from South Sumatra). All these tribes running the different farming systems, new comers and indigenous farmers implement farms with rice monoculture, while spontaneous migration applied multi commodities. The average land ownership of farm households is 1.95 ha which is intended for rice fields (0.94 ha), estate (0.85 ha), and livestock and fisheries (0.16 ha). Indigenous farmers have the minimum land (0.75 ha), however the spontaneous migration has the largest lands (3.10 ha). The larger the land ownership by farmers, thus the farmer’s income will increase if the land is cultivated by farmers. Household income structure of farmers is dominated by food crop farming and this has led to the vulnerability of farmer’s income due to the uncertainty of agricultural activities. The more varied sources of farmer’s income, the income of farmers will increase also. The learning process of spontaneous migration indicates that the farm should follow the nature, so the coercion of nature means to increase operational costs of farming.Keywords: Livelihoods, household, income, indigenous technology, wetlands

Abstract

This study aimed to analyze the bacteria population, the release of CO2, pH and organic-C and total-N in the process of compost made from manure and swamp grass. Treatment level consist of 100% manure (K100), 50% of manure + 50% swamp grass (K50R50), 25% of manure + 75% swamp grass (K25R75), and 10% of manure + 90% swamp grass (K10R90). The result of this study indicated the dynamic of different bacteria population on different composting materials by increasing of the composting time. The release of CO2 decrease on all treatment levels  by increasing of the composting time. The pH value increased at all levels of treatment, except the composition of 100% manure. The best composition obtained by mixing of 10% manure and 90% swamp grass.Keywords: CO2 release, compost, manure, population, swamp grass.

Abstract

Diversity 22 local varieties of rice South Sumatra has the potential to be developed into rice varieties. The similarity (similarity) among 22 local varieties of rice South Sumatra became one of the obstacles for scientists to develop rice varieties. One solution to this problem is to determine the genetic relatedness between 22 rice local vaietas South Sumatra. Identification of genetic relatedness among 22 local varieties of rice South Sumatra can be carried out using PCR-RAPD. This study aims to determine the phylogenetic relationship among 22 local varieties of rice South Sumatra. This research about DNA isolation and visualitation has been carried out in August 2015 until December 2015 in Microbiology Laboratory and Laboratory of Genetics and Biotechnology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya and research about DNA quality and quantity test and PCR-RAPD has been done in Biotechnology Labotory Faculty of Mathematics and Natural Sciences, Sriwijaya University. Obtained 22 local varieties of rice accessions South Sumatra. Genetic relatedness identified using PCR-RAPD technique. 7 primer (OPA, OPA-9, OPA-10, OPA-13, OPA-16, OPA-19, OPB-8) was used for amplification. Local varieties of rice South Sumatra is divided into two major groups in association coefficient of 0.76, namely groups A and B. Group A consists of groups A1 and A2 in association coefficient of 0.78. In the large group B also consists of two groups: the B1 and B2 in association coefficient of 0.84. Local varieties of rice genetic relatedness South Sumatra are not influenced by geographical location.Keywords: Local Varieties Of Rice South Sumatra, Genetic Relatedness,  PCR-RAPD

Abstract

The fragmentation of forest vegetation cover can be measured quantitatively, using tools that can characterize the geometry and spatial properties of the patch or patches of mosaic, which depicts the forest loss and the changes in the temporal pattern.   The aims of this paper are to observe the process of the forest fragmentation, to find out the changes of spatial patterns of habitat continuum by applying the spatial dynamics change analysis of the forest fragmentation phases, and to provide the comprehensive approach in determining the rapid change of the forest landscape structure in the spatial transformation process, based on the decision tree models.  We find three phases of the forest fragmentation were identified, namely dissection, dissipation, and attrition.  This study shows that the production forest area and a wildlife conservation area that contiguous or borders, has the same phases in the process of fragmentation of the forest, but both have a difference of the magnitude of forest loss.  We find there are at least five effects of forest fragmentation to the landscape structure, those are  increasing in a number of habitat patches, decreasing in a size of habitat patches, reduction in a habitat amount, increasing in a dispersion and interspersion of patch types, and reduction in a size of spatial connectedness between patches.Keywords: fragmentation, landscape metrics, spatial transformation.

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
