Abstract

Hydro-physics of peat soils varied with their peat decomposition degree. One of the important hydro-physics is ability of the peat soil to release water as decreasing water table. Potential of water availabilty to crop growth is evidently related to this behaviour. The present study was conducted to understand modes of moisture release of peat soils as decreasing water table. Water tables were simulated using a hanging column method. The water table was arranged at levels of 0, 10, 20, 30, 50, and 100 cm below peat column surfaces. Potential of moisture release or in oppositely potential of moisture retention could be modelled with the 3 parameter equation. Highly decomposed peat characterized by higher bulk density and lower total porosity stored less water but retained more water.

Abstract

Leachate is wastewater that contains pollutants dominated by organic matter. Conventional leachate treatments have some disadvantages therefore alternative treatments are needed. One of that alternative treatments is ultrafiltration membrane and adsorption as pretreatment. The aims of this study are to analyze adsorption isotherm and kinetic model for UV254 (UV adsorbance at 254 nm wavelength) adsorption, the performance of powdered activated carbon (PAC) adsorption and ultrafiltration membrane hybrid process for UV254 of leachate removal, and the effect of pretreatment towards membrane fouling. The result of this study are Freundlich isotherm and pseudo second order kinetic model best fitted model for ultrafiltration membrane hybrid process condition for UV254 removal level are at pH 6; 120 minutes contact time; and 4 g/L PAC doses. Adsorption as pretreatment can reduce membrane ultrafiltration fouling.

Abstract

Land conversion is the result of the growth for the urban population. Conversion of green open space (RTH) for development can lead to change in environmental quality. One of the impact to change in environmental quality due to conversion of green space is the increase in local temperature of the city. The existence of RTH have considerable benefits to improve the environmental quality of the city, such as amelioration of microclimate. The aim of this research is to analyze the microclimate and discomfort index of park city for the Komet Village of Banjarbaru City. Microclimate condition as categorized "discomfort expressed by > 50% of the population" to "discomfort expressed by the majority of the population". This condition is affected by the average daily air temperature and the average daily humidity which high at the study site, resulting cause the high of discomfort index  felt by the population especially in the daytime.

Abstract

This study analyzes the level and status of greenhouse gas emissions or removals from solid waste management activities in Marabahan Subdistrict, Formulates an action plan for solid waste management that is low in Greenhouse Gas emissions in Marabahan Subdistrict and Projects the level and status of emissions or Greenhouse Gas absorption from waste management solid in Marabahan District until 2030, according to the 2006 IPCC BAU scenario and mitigation actions. The waste sector greenhouse gas emissions inventory results in 2016 reached 5.16 Gg CO2-eq. However, due to improvements in domestic waste management, the 2016 greenhouse gas emissions rate was reduced by 11.1% compared to the BAU scenario. In 2016, waste sector greenhouse gas emissions in the BAU scenario are projected to reach 10.61 Gg CO2-eq, and will continue to grow until 2020 to 11.14 Gg CO2-eq, and in 2030 to 12.64 Gg CO2-eq. In Action Mitigation I waste management is carried out in the community by implementing methane recovery in the waste banks and TPS 3R. In Action Mitigation II, waste management is carried out at the Final Processing Site (TPA) carried out by the local government to handle it. When compared to the BAU scenario, the design of mitigation actions I and II in the context of reducing greenhouse gas emissions resulted in a decrease of 35.2%, 59.5% and 98.3% in 2013, 2020 and 2030.

Abstract

This study was conducted to find out  the value of the drainage coefficient of the office area in South Kalimantan under the existing conditions, the effect of land use changes on fluctuations in discharge at Embung Kampung Banjar and the green open space that must be available with the existence of Embung Kampung Banjar. The existence of Embung Kampung Banjar is expected to reduce the impact of excessive rainfall which causes various kinds of natural disasters. This study usesd the Rational Method analysis to get the value of rainfall intensity in determining the planned discharge, the method of analysis of the coefficient of flow and the research method used for discharge fluctuations in Embung Kampung Banjar that is simulated with the synthetic unit hydrograph ITB –2 Kirpich, Snyder and Mononobe which all calculations by useng Microsoft Excel . The results shows that the simulation of land use change by adding the area of residential housing and offices are evidence of reduced open areas. The calculation of the maximum discharge coefficient of the existing flow using the Synthetic Unit Hydrograph (HSS) ITB 2 Timelag Kirpich of 7.83 m3/s and the results of flood tracking caused a decrease in peak discharge of 5.4 m3/s the largest land use change was found in the flow coefficient is 0.499 with a maximum discharge of 9.69 m3/s where the housing area is 0.85 km2 and offices are 0.47 km2. In Indonesian Law Number 26 of 2007 on Spatial Planning Article 29 paragraph 3 regarding the proportion of Green Open Space (RTH) about 20 percent of the city area. The calculation results of the peak discharge capacity of Embung Banjar Kampung which is equal to 6.8963 m3/s equal to 15 percent of the flow area of Embung Kampung Banjar which is obtained from the maximum discharge calculation, which is 9.69 m3/s. Then the results of the routing flood that caused a decrease in the discharge amounted to 6.6 m3/s, so the overall result is that the reservoir is still safe if overflow occurs in the reservoir.

Abstract

Tabalong Regency with an area of 3.946 km2, has a forest area of 2,087 km2; featuring lively activity going on illegal logging. The impact of environmental losses arising from the practice of illegal logging currently has been very well perceived by the people who live inside and outside of the Tabalong Regency. A variety of protective measures and safeguards the forest against illegal logging practices have been implemented, but not yet a lot of fruition. This is because the efforts that have been made less touched on the main problems of illegal logging practices, so I need to know the primary cause factor of occurrence of illegal logging practices in order to be compiled a concrete action and policy formulation that is strategic in preventing illegal logging practices. This study aims to explore the main factors that led to the practice of illegal logging in Tabalong Regency, as well as how prevention strategies. This research uses qualitative research methods with approach case studies, using interview techniques, observation and study of the literature. The results showed that the main factor is the cause of rampant illegal logging practices in Tabalong Regency is not effectively monitoring and control the administering of wood in preventing the occurrence of illegal logging practices. This is the cause of the occurrence a mode of “bleaching” against the wood results in illegal logging. Strategy of prevention of illegal logging in Tabalong Regency will need to be directed at efforts to increase the effectiveness of oversight and control over the administering of wood in preventing the occurrence of illegal logging practices through the powers given to the provincial government as well as the County Government, including efforts to: (a) monitoring and control the administering forest products derived from forest rights and (b) monitoring and control the administering forest products on the timber industry.

Abstract

Pondok Pesantren Ibnu Mas’ud Putri merupakan salah satu pondok pesantren modern yang berada di Provinsi Kalimantan Selatan. Pembakaran sampah organik masih sering dilakukan mitra saat ini dengan alasan efisiensi waktu, tenaga, dan biaya. Kebiasaan tersebut akan memberikan dampak negative bagi lingkungan. selain meningkatkan gas rumah kaca, pembakaran dapat merugikan tanaman di sekitar lingkungan mitra karena tidak mendapatkan pengembalian bahan organik pada media tumbuh yang memang memiliki status kesuburan tanah rendah. Permasalahan mitra terdiri dari pengetahuan dan keterampilan dalam pengelolaan sampah organik yang ramah lingkungan masih belum optimal, terbatasnya tenaga dan waktu mitra dalam pengelolaan sampah karena kegiatan harian yang sangat padat, serta konservasi tanah di sekitar lingkungan mitra yang belum optimal. Solusi permasalahan yang dilakukan pada kegiatan pengabdian adalah sosialisasi dan pelatihan pengelolaan sampah organik yang ramah lingkungan serta penerapan sistem biopori di sekitar area ponpes mitra. Kegiatan dilakukan selama kurang lebih delapan bulan. Kegiatan pengabdian terdiri dari tahapan persiapan, sosialisasi mengenai pengelolaan sampah dan sistem biopori, pelatihan pengolahan sampah organik dengan menggunakan biodekomposer, pelatihan dalam penerapan sistem biopori, pendampingan pengembangan sistem biopori, serta monitoring dan evaluasi kegiatan. Sosialisasi yang dilakukan tentang pengelolaan sampah organik dan system biopori di Pondok Pesantren Ibnu Mas’ud Puteri dapat meningkatkan pengetahuan dan wawasan masyarakat pondok. Pendampingan penerapan system biopori mendapat respon positif dari mitra sehingga santriwati dan pengelola pondok terlibat aktif dalam pembuatan sistem biopori.

Abstract

Most farmers in tidal swamp areas optimized their land by using inorganic and organic fertilizers. The inorganic fertilizer has limited to get while many organic matter resources such as water hyacinth, Azolla, Kayapu, crop waste (straw), and rice husks widely available. This local potential supported the adoption of sustainable organic farming systems on tidal lands, particularly in South Kalimantan. The utilization of straw can be applied directly to the soil or made into bokashi. Therefore, an experiment of rice straw and bokashi of rice straw application to restore the fertility in the tidal swamplands had been conducting. This study used a completely randomized design method (CRD) with a single factor with five treatments: control, rice straw 2.5 and 7.5 tons ha-1 bokashi 2.5 and 7.5 tons ha-1. Each treatment had been repeating four times. The results showed that the application of bokashi of rice straw could increase soil pH, N-ammonium, and N-nitrate in the soil. On the other side, the application of fresh rice straw could reduce the soil's N-ammonium and N-nitrate content

Abstract

Peatlands are developed for the cultivation of plantation crops such as oil palm. However, recently the focus on the development of peatlands for this activity has been so great, especially in relation to the emission of carbon dioxide CO2 into the atmosphere during land clearing, burning of biomass and maintenance of oil palm. The potential for peatland to be used as agricultural land must pay attention to environmental aspects such as the level of CO2 emissions to these changes. This study aims to determine the effect of wood charcoal and empty oil palm fruit bunches on CO2 emissions and their relationship to C-Mic and C/N ratios on peatlands overgrown with oil palm. This study used a randomized block design. The factors studied were the distribution of wood charcoal and empty palm fruit bunches at four levels, namely: control; wood charcoal 0.75 kg; empty palm fruit bunches 0.75 kg and empty palm fruit bunches 0.375 kg + wood charcoal 0.375 kg. Each treatment was repeated 3 times, so that 12 experimental units were obtained. The results showed that on day 0 and day 45 the addition of wood charcoal and empty palm oil bunches had no effect on CO2 emissions, but on day 15 the results showed that the treatment had an effect on CO2. emissions and soil microorganisms (C-mic). Unstable C/N ratios and value of CO2 emission increased or decreased when sampling on different days.
