Abstract

The conversion of agricultural land into residential areas will have an impact on the need for clean water which contains various metal contaminants such as iron. One of them is the Randu Housing, Sumberejo Village, Sukodono District, Lumajang Regency, which is one of the many housing estates built from former rice fields. This study aims to analyze the effect of using types of aerators, namely cascade aerators and bubble aerators with a variety of filter media using dune sand and river sand with a discharge of 1 liter/minute. This type of research uses an experimental method which is carried out on a laboratory scale. The results showed the percentage reduction in Fe content in aeration treatment using cascade aerator and bubble aerator was 14,55% and 2,16%, sedimentation treatment was 3.34%, and filtration treatment using dune sand and river sand filter media was 81,85% and 89.13%. The results of the analysis showed that the variables of the cascade aerator, dune sand filter and river sand filter had a significant relationship with the decrease in iron content. While the relationship that does not have a significant effect is the bubble aerator and sedimentation variables. Keywords: Aeration, Sedimentation, Filtration and Iron (Fe)

Abstract

The carrying capacity of water resources for various uses is highly dependent on the condition of the quality, quantity and continuity of water in a watershed. The lack of research conducted in the Poleang Watershed greatly limits information regarding the carrying capacity of the watershed. This study aims to determine the carrying capacity of the watershed based on water management indicators in the Poleang watershed. The method used in this study uses Minister of Forestry No. P.61/Menhut-II/2014 concerning monitoring and evaluation of watershed management with 5 parameters namely Flow Regime Coefficient, Annual Flow Coefficient, Sediment Load, Flood, and Water Use Index. The results showed that KRA in the Poleang watershed was in the category of KRA ≤ 20 with very low class, KAT was in the category of 0.2 < KAT ≤0.3 with low class, MS reached 97.25 tons/day so it was in the category of M> 20 with very high class, flooding occurs 1 time a year with high class, IPA reaches 1,299.9, so it is in the category of IPA ≤1,700 with very bad class. So that it can be concluded that the carrying capacity of the Poleang water system is included in the medium carrying capacity class

Abstract

Balikpapan City is a city that does not have a large river to supply raw water like in several other cities, so to meet the water needs of the community, the main source of raw water is obtained from surface water from the Manggar Reservoir. The presence of high amounts of organic contaminants such as BOD and COD will affect water quality if treatment is not carried out to reduce these pollutants. One of the efforts that can be made to reduce pollutant levels is by the adsorption process using natural adsorbents, namely activated carbon from cassava peels. This research was conducted to find out how the effect of mass, contact time and the effectiveness of adsorbents from activated carbon of cassava peels in reducing BOD and COD levels in Manggar reservoir water, Balikpapan City. The adsorption process was carried out using variations in mass of 1, 3, 5, 7 and 9 gr and contact time variations of 30, 45, 60, 75 and 90 minutes. Based on the results of the study, the efficiency of reducing the BOD concentration of the adsorbent of activated carbon from cassava peels was 95.06% from the initial concentration of 8.3 mg/L to 0.41 mg/L at the optimum mass of 5 grams and the efficiency of reducing the COD concentration was 100% of the initial concentration of 28.54 mg/L to 0 mg/L at an optimum mass of 3 grams with a contact time of 30 minutes. From the results of the statistical analysis tests performed, it was found that the mass variation of the adsorbent did not significantly affect the decrease in BOD and COD concentrations, while the contact time had a significant effect only on the decrease in BOD concentrations.

Abstract

Abstract Sembalun is well known as one of tourism destination in Lombok Island with main attraction is Rinjani Mountain hiking. Currently, there are also some other tourism attractions such as hill climbing, garden and fruit tours, and photo spots. In addition, many people come to spend their weekend in Sembalun. The increase in the number of tourist visits to Sembalun is an opportunity to develop various Sembalun souvenirs. One of them is Sembalun black garlic. Black Garlic Sembalun uses garlic as a raw material. The purpose of this study is to estimate the carbon footprint of Sembalun black garlic production where the method used is a Life Cycle Assessment. The unit function used is the production of black garlic in a month. A case study was taken from the UMKM KWT Putri Rinjani in Sembalun Bumbung Village which produces black garlic. There are five stages in the black garlic production process, namely transportation, drying, peeling, roasting, and packaging. From the results of the analysis using the OpenLCA software, three process stages contributed to the carbon footprint of Sembalun black garlic production, namely the transportation stage (52.125 KgCO2eq), the roasting stage (46.707 KgCO2eq), and the packaging process (6.930 KgCO2eq). To reduce the carbon footprint, several sustainable improvement alternatives that can be carried out include storing (stock) raw material to reduce the number of transportation trip and using transportation vehicles that have better combustion efficiency and the use of electric vehicles. Keywords: carbon footprint, black garlic, transporting, roasting, packaging.

Abstract

Mercury contamination caused by artisanal gold mining waste would become an environmental problem if there were no remediation actions. This study aimed to investigate the ability of natural zeolite obtained from Gunungkidul Yogyakarta to stabilize mercury in mining waste or tailing. Tailing samples were obtained from three locations on Kulon Progo, Wonogiri, and Banyumas, and the natural zeolite sample was obtained from Gunungkidul, Yogyakarta. The batch experimental study was conducted to test the ability of the effectiveness of natural zeolite in stabilizing mercury in tailing. The result of the study shows that the natural zeolite used in the experimental study can be used to reduce the mercury concentration in tailing. The natural zeolite's ability for stabilization varies and depends on the initial mercury concentration in tailing and the natural zeolite dose.
