The main problem for agriculture at tidal lowland swamp is low soil quality and high acidity of soil and high water. The research objective was to investigate how far the effort in increasing tertiary canal network to improve water quality (increasing pH and reducinf iron) in channel and tertiary plot. Field study was conducted at Bandarjaya Village of Jalur 25, Delta Sugihan Kanan, South Sumatra. Field activities were consisted of network investigationÂ land use and farm enterprise system which located at Primr 13 of Sugihan Kiri and Primer 25 of Sugihan Kanan. The network improvement perfomance was conducted by constructing micro water management (installed the tertiary gate and developen quartey canal) at tertiary plot which consisted of collector channel, sub tertiary channel and control plot which was outfall at quarterly channel downstream end. Water gate having goose neck pipe system was constructed to control water table in tertiary channel. Results of field study showed that land use at the study area was still dominated by rice crop with magnitude of 83% and the rest of 17% was used for rubber plantation, orange planation and mix plantation. The depth of phyrite layer was in the range of 60 to 100 cm below soil surface. Water table surface in October was in the range of 10 to 35 cm. Field adaptation showed that water gate was operated in closed condition (water retention) during vegetative phase. Water retention showed significant to improve rice yield in which water table since November had increased from -10 cm to flooding condition of 15 cm in January. This condition provide sufficient water for rice crop which was similar as the result found at irrigation area. The addition of ameliorant substances such as coconut fiber, and sand semen block at outfall of tertiary and kuartely channels also increase water quality in which water pH was increased fromÂ 2.95 to 3.7 and iron concentration was decreased from 4.01 to 0.32 mg/liter. Rice yield was increased from average production of 2 ton/ha to 3 ton/ha. This low production was due to land flushing process which need longer time process for at least 2 to 3 years from current condition as well as other production inputs such as fertilization and ameliorant substances.

The change of Banjarbaru city status into the central government of South Kalimantan Province, has the potential to increase the need for land. This directly affects wetlands conversion activities into other forms of land closure. This research aims to map the spatial distribution of wetlands, and the spatial distribution of wetlands conversion existing in Banjarbaru City in every decade over the last four decades, ie from the 1970s to the present. Wetlands spatial data are extracted from multitemporal satellite imagery, Landsat 5 in 1973, Landsat 5 in 1989, Landsat 5 in 1997, Landsat 5 in 2007, and Landsat 8 in 2016. The method used to extract wetlands is Object Based Image Analysis (OBIA), with Full Lambda-Schedule algorithm. The research results show that over the past last decades, the total area of Banjarbaru City's wetlands has been reduced continuously. The average total reduction rate is 534.53 hectares per decade or about 53.5 hectares per year, with a linear pattern over the past four decades.

Fires in Indonesia tropical peatlands are always associated with peatland conversion. Land use change usually occurs from secondary or primary forest to agricultural land or plantation. However, land use change in Indonesia is inevitable because high demand of land for food supply. Peatlands which are usually associated with wetlands, become dry due to drainage during land clearing and plant growth process. Therefore, the relationship between ground water level (GWL) and fires on tropical peatlands is close. The research objective is to analyze the level of fire vulnerability on peatlands based on the GWL fluctuation under different land uses. GWL measurement was conducted manually every week from February to December 2014 in the field and ditch on three different land uses. Automatic water level measurement tool also conducted from March to December 2014, but only on the field. GWL fluctuation both on ditch and field followed the variation of precipitation. GWL fluctuation under different land uses also significantly different, and automatically results different fire vulnerability.

A goal of timber harvesting is to increase timber production through removing the timber Â from the forest using some harvesting techniques. Â A peatland is a fragile ecosystem and may degraded easily. Logging activities may adversely affect the soil compactness that disrupt the peat drainage system as well as cause subsidence, then ultimately may cause the sustainability of peat. Â This study was focused on examining the effect of timber harvesting acivities in peat forest plantation.Â The peatland damage may in the form of increased bulk density, water level fluctuations of peat (TMA), subsidence, irreversible and carbon emissions. Â The objective of the Â study is to find out the effect of timber harvesting in peatland plantations to peat water fluctuations and subsidence. Â The results showed that logging activites caused : (1) The average of water table and water level are about 1.03 and 0.967 m; and (2) Subsidence about -8 to -12.5 cm with the average is -11.0 cm.Â

Publisher : Center for Journal Management and Publication

The purpose of this study is to determine the Accounting treatment of biological assets based on IAS 41 Agriculture. DSAK-IAI in the process of convergence of PSAK with IFRS states that one of the standards that is still being project remaining work since 2010 is IAS 41. IAS 41 is adopted into PSAK No.69 Agriculture as the Accounting standard that regulates special biological assets that will be effectively applicable on 1 January 2018. The results of this study are expected to provide the description of Accounting treatment based on IAS 41 in more detailed and clear in terms of recognition and presentation and disclosure of biological assets. However, in terms of measurement, IAS 41 will be more difficult to implement because the market price for the plantation industry has not been able to be a benchmark of fair value.Â Â Â Â Â Â This research was a qualitative descriptive research by giving a description of the Accounting treatment of biological assets engaged in oil palm plantation. Data collection techniques used questionnaires sent to the company with 10 (ten) samples of oil palm companies representing Banjarmasin City, Banjarbaru City, Banjar Regency, Tapin Regency and Tanah Laut regency. The data were analyzed by using descriptive analysis and index calculation of implementation conformity to the standard. Â Â Â Â Â Â The results showed that the companies have applied the Accounting treatment of biological assets on the average of 90.8% based on research indicators. In terms of classification the companies have classified 100% of its biological assets well. Recognition, measurement and assessment of biological assets, the companies applied research indicators in the range of 84% - 97%, this condition was caused more because the basis of valuation with the fair value of biological assets was not readily available in the active market thus affecting the recognition, measurement and valuation of those assets. While Presentation and Disclosure of Biological Assets in the financial statements, the companies applied 77.5% - 96% of the existing disclosure indicators.Â Â Â

Hot water- and water-extracted organic matter was extracted from soil samples collected after a 31-year long-term experiment which aimed to assess the effect of different fertilization strategies (inorganic fertilizers and organic matters) commonly used for paddy rice cultivation in Yamagata, northeastern Japan. The ratio of soil to extracted water was 2:3. The amounts of hot water-extracted organic carbon and nitrogen (HWEOC and HWEN) at 80 oC and 16 hours, water-extracted organic carbon and nitrogen (WEOC and WEN) at room temperature, and their Î´13C and Î´15N were measured from the five fertilizer treatment plots as [1) PK, 2) NPK, 3) NPK + 6 Mg ha-1 rice straw (RS), 4) NPK + 10 Mg ha-1 rice straw compost (CM1), and 5) NPK + 30 Mg ha-1 rice straw compost (CM3)], for surface (0-15 cm) and subsurface (15-25 cm) layers. HWEOC and WEOC accounted for an average of about 1.51 and 0.66% of SOC, while HWEN and WEN accounted for an average of about 1.09 and 0.40% of soil TN, respectively. About 90% of the extracted N was organic form among all treatments. The values of Î´13C for HWEOC and WEOC ranged from -28.2 to -26.5â€° and from -28.3 to -27.0â€°, similar to the original rice straw and rice straw compost, and lower than the value of original soil at -22.5â€°. The values of Î´15N of HWEN, WEN and bulk soil ranged from 0.8 to 3.8â€°, from 1.0to 4.0â€°, and from 0.8 to 2.8â€°, respectively. It was clear that Î´15N decreased in RS but increased in CM3 treatments. Our results indicated that the amounts of hot water- and water-extracted organic matter were affected by long-term application of inorganic fertilizers and organic matters remarkably. However, the values of Î´13C for HWEOC and WEOC were not different among 5 treatments, but values of Î´15N of HWEN and WEN were affected by RS and CM3 applications clearly.

Silk Sarong Samarinda is a sarong typical samarinda made using imported silk thread from China. Quality mulberry plants are needed to support the cultivation of silkworms (sericulture). Quality mulberry plants are obtained by in vitro propagation techniques. The success of in vitro culture needs to be supported also by the growth medium suitable for acclimatization stage and plantlet growth. As the medium grows peat has several advantages that are light, water-binding power and high air, porous and can create a good environment for the development of plant roots. Acclimatization by using peat media done in glass house. This research uses Completely Randomized Design (RAL) method with 5 (five) kinds of growing media combined with manure, compost and charcoal husk and without fertilization as control. Peat soil media successfully used for the growth of mulberry acclimation. Of the 5 (five) growing media attempted, the best growth of mulberry plants is on peat-growing medium: manure: charcoal husk (1: 1: 1) until 12 weeks after planting (MST) the addition of the number of shoots, the addition of the number of leaves as well as to the growth of plant height where at that height mulberry plants ready to be planted in the field.

Publisher : Center for Journal Management and Publication

This study on the Songor Ramsar and UNESCO Man and Biosphere Reserve in Ghana seeks to ascertain management method to promote sustainable management of wetlands.Â The findings clearly indicated that good management practices are employed in the management of the Songor Ramsar Site. The current approaches to management have focused on the harmonious fusion of modern scientific strategies and cultural and traditional methods. In the Songor Ramsar and UNESCO Man and Biosphere Reserve, traditional authorities have enacted traditional rites such as sacred groves and totems in the Ada East District which are strictly enforced to provide traditional regulatory support for their protection while modern conservation approaches in the Songor Wetland management utilizes all the laws in legal protected areas in Ghana. Management also embark on training programmes for users of the wetland resources in sustainable resource utilization to improve economic livelihood.Â Increased public education and sensitization on the economic importance of the Ramsar Site and the negative impact of environmental degradation has been part of the management strategies. The Public education is on environmentally sound management of waste within the Ramsar Site since the underlying causes of environmental degradation in the Songor Ramsar Site are mainly improper waste disposal, poor attitude of residents toward environmental conservation, wildfires and shoreline recession, inadequate public education on the impact of environmental degradation, fishing, and farming activities. The other factors identified include overgrazing, over exploitation of mangroves, predation, poaching and over fishing, and uncontrolled sand and salt winning

A pot study was carried out to investigate the effects of rice husk biochar addition on rice growth performance and fertilizer nitrogen recovery. The biochar effect was studied by using 15N labelled fertilizer urea (10 atom% 15N), as isotopic tracer, until maximum tillering stage (75 days after sowing). Rice husk biochar (RHB) was applied at rates of 0, 5, 10 and 20 Mg ha-1 and laid in randomized complete block design with four replications. The result showed that biochar application significantly improved soil chemical properties (pH, total C, total N, and available P) compared to control treatment. Biochar addition increased number of tiller and root dry matter weight up to 4% and 35%, respectively, compared to un-amended pot. Likewise, application of biochar significantly increased N, P and K uptake by 3%, 19% and 33%, respectively, as compared to the nutrient uptake from the control treatment. Biochar treatment had no significant impact on fertilizer nitrogen recovery in aboveground biomass, in the range of 41% and 42%, in comparison to the control. However, nitrogen fertilizer recovery in soil significantly increased by 47% over the control at application rate of 20 Mg ha-1 RHB. Â Increased fertilizer N recovery in soil possibly reduced N losses to the environment from volatilization and denitrification processes. Total 15N fertilizer recovery also found increase at highest application of RHB biochar with an increment of 16%. In general, addition of biochar appeared to enhance crop growth performance but its effect on fertilizer N recovery in plant requires further study up to maturity of rice plant.
