Water Quality of Canal For Sustainable Aquaculture In Reclaimed Tidal Lowlands
Raudhatus Saadah PASCA SARJANA UNIVERSITAS SRIWIJAYA Indonesia , M. Rasyid Ridho , Momon SodikThe reclaimed tidal lowlands in Banyuasin, South Sumatera, Indonesia were initiated by making water canals that separate some areas to be some land groups. Those water canals are used for some activities such as agricultural, plantation, housing and water source for the people activities. This research aimed to observe the eligibility of water canals for sustainable fish culture. The data analysis of water qualities included ammonia, phosphate, nitrate, TSS, DO, pH, temperature, EC, salinity, water depth, detergent, and organochlorines. Cluster Test was used to analyze the data to compare the water qualities among canal areas. The results showed that detergent concentration was quite low, ranged at 63,5-74,5 ppm. Organochlorine found were Dieldrin 0,0084 ppm, while Linden, Eldrin, Heptklor, DDT, and Endosulfan concentration were below 0,001 ppm. Cluster Test showed that water quality in the canal was still in good condition, and can be used to support fish culture.

Elisa Wildayana Sriwijaya University Indonesia , M. Edi Armanto , Imron Zahri , Dessy Adriani , Bella SyakinaNaturally peatlands ecosystem belongs to a stable ecosystem and tends to increase its peat thickness, but if the balance of its natural conditions is disturbed, then peatlands are easily degraded and lost altogether. The research aimed to analyze the socio-economic determinant factors causing why peatlands in South Sumatra are rapidly degraded, thus it is threatening the existence of the human life support system. The research method was using an explorative and descriptive method by making the web portal of "Google search engine". Keywords were used for searching ‘peatland’, ‘degradation’ and/or ‘socio-economic causes’ in title and abstract. To analyze priority level of socio-economic aspects in contributing to peatlands degradation, thus an AHP analysis was conducted and interview with selected respondents. The research resulted that socio-economic determinant factors causing peatlands degradation are complex and integrated each other. Based on clustering the main sequence of causing peatlands degradation was performed by increasing population; increasing poverty; win-win approach; security of land ownership; and agricultural infrastructure and expansion respectively. Understanding this cluster with a comprehensive approach is needed to decide what factors play in the degradation of peatland, so that the policies made are precise and targeted. At this time the government requires to restore peatlands, so that peatlands can be preserved forever.

Khairul Fahmi Purba Sriwijaya University , Muhammad Yazid Sriwijaya University IndonesiaTidal lowlands bear enormous potential including crop production.  However, tidal lowlands also have numbers of ecosystem functions that prevent them from exploitative uses. Therefore, tidal lowland utilization for crop production should consider measures to achieve sustainable development goals (SDGs) in one hand. In the other hand, SDGs should also ensure the sustainable use of tidal lowlands. This paper aims to review the sustainability of crop production in tidal lowland to support the achievement of SDGs, which are eliminating hunger, achieving food security with good nutrition, and improving sustainable agriculture. These goals need to be achieved in 2030 by ensuring sustainable crop production systems, applying tough agricultural practices, increasing production and productivity, and at the same time maintaining tidal lowland ecosystems. Therefore, this paper will review three major aspects as follows: (1) productive means of crop cultivation, (2) effective control of agricultural waste and pollutant, and (3) efficient use of agricultural inputs. This review is expected to yield sustainable measures of crop production in tidal lowlands to contribute to the achievement of sustainable development goals (SDGs).

Meitry Firdha Tafarini Sriwijaya University , Muhammad YazidWater in tidal lowlands may either lack or excessive. Neither lack nor excessive of water is demanded for crop cultivation. Therefore, water management plays an important role in the development of tidal lowland agriculture through maintaining proper water conditions. Since tidal lowland with certain conditions is considered marginal, its utilization for crop cultivation should maintain its fragile characteristics such that its utilization to support crop production can be sustained. Continuing use of tidal lowlands for crop production, therefore, requires agricultural ecosystem management through the establishment and measurement of sustainability in water management. Sustainable water management in tidal lowlands for crop production should not only consider the physical resources (infrastructures), but also human resource as well as financial resource. This paper proposes three agendas for research on water management as follows: (1) identification of specific local water infrastructure developments, (2) initiation of participatory operation and maintenance of water infrastructures, (3) utilization of self-supporting financial means in water management.

Marini Wijayanti Sriwijaya University; Universitas Sriwijaya Indonesia , Dade Jubaedah Universitas Sriwijaya Indonesia , Nuni Gofar Universitas Sriwijaya Indonesia , Devi Anjastari Universitas Sriwijaya IndonesiaPangasius is a fast-growing fish species that has great potential for production and export growth in Indonesia. Their farming produces a lot of organic material and ammonia which potentially make polution in freshwater body. The wastewater can be used for high value microalgal cultivation media. The microalgae are used in various fields, one of those is Spirulina platensis, a spiral blue green algae. This aims of this study was to determine the best composition of the technical fertilizer in the pond waste of Pangasius farming pond to obtain maximum density and know the spesific growth rate of Spirulina platensis. The research method used Completely Randomized Design (CRD) with 6 treatments (3 replication), P0 using 100% technical fertilizer without using Pangasius waste water while P1-P5 use 0% (P1), 25% (P2), 50% (P3), 75% (P4) and 100% (P5) technical fertilizer using Pangasius farming waste water. The most efficient treatment obtained 23.90 gL-1 maximum density, 6.22%.d-1 specific growth rate and 87.77% ammonia removal.

Dessy Adriani Sriwijaya University , Elisa WildayanaThe ecological constraint of tidal lands necessitates agricultural innovation in the related area. But technological innovation, however, make the disguised unemployment worsen in tidal land. Income diversification is expected to be a solution to the rising number of disguised unemployment-associated agricultural innovation. Both combined will offer a solution to cope with the issue of disguised unemployment. This study is aimed to analyzing strategies used to cope with disguised unemployment in the tidal agricultural sector through a combination of technological innovation and income diversification. The study was carried out in the tidal lands in Province of South Sumatra, Indonesia in 2017. This study employed a quantitative method with a survey technique. Simple random sampling was conducted to determine each subject population.The analysis was carried out using tabulative, mathematical, and simulation method. Technological innovation in agriculture gave to the rising number of disguised unemployment in tidal agriculture sector. But, with technological innovation and income diversification, disguised unemployment will be decreased and farmers' income will be increased, yet, the productivity will be low. In other words, to cope with the issues of disguised unemployment, technological innovation in the agricultural sector should be accompanied with the income diversification. However, we should be noted that the combination of agricultural technology innovation policy and income diversification affects to decreasing on household productivity The results are, by and large, useful for policy makers in designing in arranging disguised unemployment policies.Â

Akash Talapatra CUET BangladeshThe capturing process of CO2 directly from air has been developed largely considering with commercial scale in pilot plants. This is done so that the capture CO2 from air can be used as a feedstock or raw material for producing carbon free renewable fuels by applying direct air capture (DAC) process. This way of capturing is gone to be possible with using some solid & aqueous sorbents in pilot plant. The success of this capturing process is depended on the appropriate configurations of both major & minor plant operations. Heat & mass balance are required necessarily to contribute on the finding of each pilot plants data. The design of this process is modeled like this so that the captured CO2 can be delivered at 15MPa into the pilot plant & for this, the requirements of energy inputs are about 8.81GJ or 5.25GJ of natural gas & 0 KWHr or 336KWHr of electricity respectively. Then all the results finding from the pilot contactor, reactor, calciner are optimized to reduce the processing cost of the capturing process. It is observed after the ending of the process that the amount of operating cost is ranged between 50$ to 100$ to capture per ton of CO2 from surrounding air where the total levelized cost of the whole process ranges between 94$ to 232$/t-CO2. If it considers the other specific choices such as financial safety, environ mental & ecological arrangements etc. then this DAC process would be the best reliable solution to capture the CO2 from air in upcoming decades.

Vieronica Varbi Sununianti Universitas Sriwijaya IndonesiaThis study shows the interaction between the natural environment and human. Starting from the revelation of the rubber price implicate on the global changes in the relationship between the physical environment with the complex social (population, technological constraints, organization, culture, and social system) at the local level. It is important to see a variation of mutual dependence and modification of social-economic changes, especially traditional oil mining (illegal). Economic interests and environmental degradation threaten the fulfillment of the next generation needs. Data collection for this study through qualitative research method with in-depth interviews as primary data and is located in the three villages (Keban 1, Macang Sakti, and Lubuk Bintialo) Musi Banyuasin District). Social inequality triggered the exploitation of natural resources widely. Local community relations with nature is very instrumental to achieve welfare. For that, need to social engineering project system that future-oriented with the collaboration of local communities, corporation, and government. But the political will to achieve sustainable development should be started by the government (state).
