Abstract

To simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (on land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates the ecological footprint in Palembang and its surroundings according to demographic factors and local government.  To investigate the general pattern of ecological footprint and its determinants based on the respondents’ reports, a survey was launched in October 2017. As a result, the average ecological footprint in Palembang Metropolitan and its surroundings is 0.591 global hectares (gha).  The ecological footprint in Palembang Metropolitan and its surroundings is formed by 4 things, namely: diet and food choices, shelter/home life, transportation and lifestyle choices.  The largest portion is given by diet and food choices (26.8 percent), while the smallest contribution is contributed by transportation (24.1 percent).   Taking into account demographic factors, a high ecological footprint is owned by a group of male individuals, aged 30-39 years, highly educated, working, and after hearing and understanding climate change and ecological footprint. Finally, if observed according to the type of government, metropolitan cities have a high ecological footprint than others.  Finally, the ecological footprint of Palembang as a metropolitan city is higher than the others.

Abstract

Soil reinforcement method is one of attempt to improve technical characteristic from the soil, such as soil bearing capacity, compressibility and permeability. The Soil Column Method is one of alternatives to enhance physical characteristic by way of stabilization to improve soil bearing capacity. Rice Husk Ash (RHA) contains high silica element, Calcium Carbide Residue (CCR) contains high calcium which is able to form pozzolan when mixed upon silica. This research aims to improve soil bearing capacity by using column soil method with a mixture of soft soil, 3% Calcium Calbide Residue (CCR) and 12% Rice Husk Ash (RHA). Soil column in this research applied a single column variation with a diameter of 3,2 cm which each has 40 cm, 46 cm, and 53 cm in length and each column with diameter of 3,2 cm, 4,2 cm, and 4,8 cm. Based on the research, ultimate Bearing Capacity (qu) of soft soil without soil column was 54,03 kPa and after being given reinforcement had increased the bearing capacity value (qu). The greates increase in soil bearing capacity of the soft soil occurred in soil column variation of 53 cm in lenght with 4,8 cm in diameter where the soil bearing capacity had increased to 75,58 kPa and the percentage increase in BCR was 39,90%. Meanwhile the least of soil bearing capacity occurred in soil column that had 53 cm in length and diameter of 3,2 cm while the soil bearing capacity had increased to 64,47 kPa and BCR only increased to 19,33%

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

Gap existing in the landscape are partial practices on environment management and social programs from each of landscape stakeholders which cause cumulative duplication or incontinuity between programs. The objective of this research is to analyze production area role in the landscape environment management in South Sumatra particularly Musi Banyuasin and Banyuasin Districts. Using survey method and purposive sampling, 8 companies representatives are interviewed regarding current environment management system and the relation with external factors with landscape approach overview. The results: (1) Land-use planning should be in place prior the development of concession permit and concessions as implementer of provincial and national agendas on local investments; (2) Concession monitoring efforts could give input on the conformity towards the law enforcement in environment management which should be expressed through the year.; (3) Concessions ideally have the role as connector to community and protected areas, connecting to government programs, raising awareness as well as providing assistance in economic empowerment to the community, reducing dependency towards forests; (4) The report from wildlife and its habitat monitoring (buffer area) surrounding concession should also be shared with Environmental Agency (DLH), Forest Management Unit (KPH), National Park and Natural Resource Conservation Center (BKSDA) for potential or existing wildife corridors or ecosystem essentials area; (5) Concession could collaborate with conservation area as well as other governmental programs to maximize the impact and efficiency of the programs. Together with community and protected areas, concessions have significant area size and have the capacity and resources to also take part in the landscape management. Joint monitoring and programs would be tremendous achievement for the landscape approach.

Abstract

Mangrove is a plant generally located in tropical regions. It grows in areas with salinated to fresh water and affected by tidal along with anaerobic soil conditions, where many grow in areas that are filled with mud and contain organic material. In the process of photosynthesis, mangrove captures carbon in the atmosphere and are stored in biomass and sediment. Sediment can store carbon greater than biomass and is rich of organic matter. Research regarding carbon storage in mangrove sediment on Payung Island has never been carried out which made this research aimed to estimate carbon storage in mangrove sediment on Payung Island. This research was conducted in October 2020 on Payung Island, South Sumatra and sediment samples were analyzed by the Walkley-Black oxidation method and the sediment texture was analyzed by the Shepard triangle method. The calculation results show the dominant sediment texture was in the clay category, the average value at each station for % C organic is 5,04% and % organic matter is 8,18% and carbon deposits in sediment are 129,6 tonC/ha.

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
