Abstract

Soil contamination was commonly found in gold mining location in Selogiri, Wonogiri, and Central Java and need serious attention for remediation action. This study aimed to investigate the mineralogical characteristic of zeolitic tuff and to analyze the influence of its characteristic for lead sorption on soil in mining, as mentioned earlier location. The soil sample was obtained from around the gold mining location. The zeolitic tuff was obtained in two locations in Gunungkidul, Yogyakarta: A and B. Zeolitic tuff samples were then characterized for mineralogy content using polarization microscopes, cation exchange capacity (CEC) by using barium chloride method and XRD (X-Ray Diffraction) analysis. A batch test was conducted on a laboratory scale by shaking zeolitic tuff samples with soil samples in a CaCl2 solution. The solution was then shaken using a magnetic stirrer, and the filtrate was sampled at a specific time interval. The batch test result showed that the zeolite mineral percentage influenced the sorption behavior of zeolitic tuff in the sample and the value of CEC, which the more zeolite mineral and CEC value, the higher of sorption capacity achieved up to 58.8%. Hence, zeolitic tuff investigated in this study has a promising material for the remediation of Pb-contaminated soil in Selogiri, Wonogiri, and Central Java.

Abstract

Rusip is known to contain fermenting microbes such as lactic acid bacteria, fungi, and yeast which are almost similar to EM4. The content of bacteria contained in rusip liquid has the potential to be used as a local biocatalyst, one of which is in reducing waste in the manufacture of liquid organic fertilizer. This study aimed to examine the potential of rusip as a biocatalyst by knowing its effect in reducing fish waste into liquid organic fertilizer with different concentrations. Fertilizer was made by fermenting 200 g of fish waste with a concentration of 30%, 40% and 50% rusip liquid for 7 days. As a control treatment, 40% EM4 was used because this treatment gave the best results in decomposing fish waste in the manufacture of POC from previous studies. The results showed that the concentration of the rusip liquid biocatalyst had an effect on reducing fish waste into liquid organic fertilizer. The highest reduced waste weight and liquid fertilizer volume were produced by the P3 treatment, namely 78.7 g and 67 ml. The lowest pH value was obtained by the control treatment of 4.73 and followed by the P3 treatment of 4.9. The highest nitrogen value was obtained from the P3 treatment of 0.77%. The most dominant fertilizer characteristic was produced by the P3 treatment which produced the same visual characteristics of the fertilizer as the control treatment.

Abstract

Bayur Bay Swamp Irrigation Area (DIR) has a land area of ​​(70.88 km2), so an irrigation system with sufficient water discharge and appropriate quality of irrigation water is needed.The purpose of this study was to determine the quality and status of DIR Teluk Bayur irrigation water. Based on the regulations in force, the use of water in the DIR is sufficient for class IV quality status, but the problem that occurs in the Teluk Bayur DIR is that the water in the DIR network is used by the community to meet the needs of their daily activities. Where the use of water for daily needs is included in class II water quality. Therefore, it is necessary to measure water quality using the Water Pollution Index (IPA) method to determine the status of water pollution levels in class II water quality based on RI Government Regulation No. 22 Year 2021. From the test results, it was found that the Total Phosphate Parameter was below the quality standard so that based on the calculation results using the Water Pollution Index method, samples SA3 and SA4 were heavily polluted with pollution index values ​​of 12.43 and 12.80, where the maximum Ci/Lij values ​​were respectively respectively are 17.50 and 18.04 while the status of SA1 pollution index value is 1.89 lightly polluted and SA2 pollution index is 4.40 moderately polluted. So that from all water quality tests it can be said that the quality of irrigation water in Teluk Bayur DIR still does not meet all of the quality standard parameters that have been set. 89 are lightly polluted and the SA2 pollution index is 4.40 moderately polluted. So that from all water quality tests it can be said that the quality of irrigation water in Teluk Bayur DIR still does not meet all of the quality standard parameters that have been set. 89 are lightly polluted and the SA2 pollution index is 4.40 moderately polluted. So that from all water quality tests it can be said that the quality of irrigation water in Teluk Bayur DIR still does not meet all of the quality standard parameters that have been set.

Abstract

Energy is a factor that has a very important role in various economic activities and people's lives. The availability of energy and fuel oil is currently lacking, indicating the need to switch to alternative fuels, one of which is charcoal briquettes. Sugarcane bagasse is one of the many biomasses that can be used. as a raw material for making briquettes. The process of making charcoal briquettes requires additional material in the form of an adhesive whose purpose is to glue the charcoal powder so that it becomes a solid form. As a binder for briquettes, molasses has the potential to increase the calorific value because it is rich in carbon content derived from sucrose which is abundant in molasses. Therefore, a study was conducted to analyze the fuel characteristics of bagasse briquettes with adhesive variations in the form of tapioca flour and molasses. The parameters to be tested are moisture content, ash content, volatile matter content during the heating process, bound carbon and heating value. Research on the production of charcoal briquettes was carried out using bagasse waste with variations in the addition of tapioca adhesive and molasses. It can be concluded that the best quality briquettes are A1 briquettes, namely bagasse briquettes with 0.5 gram of adhesive drops, which are close to the standard criteria of briquettes, namely the highest calorific value, lowest moisture content, lowest ash content and lowest volatile matter content.

Abstract

Oil sludge waste is a potential pollutant for the environment and a major problem in upstream oil and gas activities. The high content of hydrocarbons in oil sludge has the potential to contaminate soil, water and groundwater. The remediation approaches, both physical and chemical, for oil sludge waste have been applied, but the costs are quite high and their effectiveness is inadequate. Two of the economical and environmentally friendly oil sludge waste processing technology options are biopile and composting. The aim of this research is to explore the application of biopiles and composting to reduce total petroleum hydrocarbon (TPH) levels. There are 4 variations in the biopile, namely B-0 (oil sludge, soil and bulking agent), B-1 (oil sludge, soil, bulking agent and inoculum) B-2 (oil sludge, soil, bulking agent, inoculum and green compost), and B-3 (oil sludge, soil, bulking agent, inoculum and chemical fertilizers), while in composting there are 3 variations namely C-0 (oil sludge, soil and bulking agent), C-1 (oil sludge, soil, bulking agent and green compost), C-2 (oil sludge, soil, bulking agent and chemical fertilizer) with an observation period of 55 days. Biopile application reduced TPH at B-0, B-1, B-2, and B-3 by 67%, 78%, 82%, and B-3 78% consecutively. Composting application reduced TPH at C-0 by 61%, at C-1 by 67%, and at C-2 by 62%. The results implies that the application of bioremediation is able to reduce TPH levels.

Abstract

Peat soil is composed mainly of organic matter, which directly impacts on the water quality in peatlands. The water in peatlands, also known as peat water, is high in organic matter, low in pH, and brown in colour. To make it suitable for daily use, such as bathing and toilet flushing, peat water must be treated. This research aims to treat peat water using Fe3O4 to reduce organic matter and a filtration process with shell sand to overcome pH and turbidity issues. The research results showed that the maximum dose of Fe3O4 to reduce turbidity is 0.0002 g/mL. Higher doses of Fe3O4 were found to increase turbidity due to the dissolution of Fe in peat water. The filtration process of peat water treated with Fe3O4 in improved pH levels that meet the quality standards. However, it also increased the turbidity due to the dissolution of fine shell sand particles in the peat water. To obtain the best conditions for effective adsorption of particles that cause turbidity, pH conditioning must be carried out before adding Fe3O4. It is also necessary to standardize the particle size of shell sand to minimize the dissolution of fine particles that can increase turbidity.
