Abstract

The presence of arsenic metal in water naturally due to its mobility causes the nature of water to become toxic and become a problem in the world. The purpose of this study was to determine the maximum adsorption capacity through the isotherm model and the rate of adsorption kinetics in the use of chitosan and coffee grounds as adsorbent in reducing the concentration of arsenic in industrial wastewater. The research method was carried out using experiments in the laboratory followed by quantitative data analysis to determine the isotherm model and adsorption kinetics. shows that the adsorption isotherm follows the Langmuir isotherm model with a correlation coefficient of 0.9972 with a maximum adsorption capacity of 2.063 mg.g-1 which indicates that chemical adsorption occurs in a mono layer with a homogeneous distribution of adsorption sites with constant adsorption energy and interactions between negligible metal arsenic (adsorbate) molecules. The study of arsenic adsorption kinetics using chitosan-activated carbon coffee grounds followed the Weber-Morris model/intra-particle diffusion with a correlation coefficient of 0.9920 with a diffusion rate of 76.512 g.mg-1.hour-1 which indicates that intra-particle diffusion is a rate step. limiting factor in the overall biosorption process.

Abstract

The river is the place where the sediment transport process takes place. One of the mechanisms of the sediment transport process is by floating in the form of suspension loads. Factors that affect the magnitude of the suspension load include flow discharge and rainfall. The study was conducted at the estuary of the white sandy beach in Sukajaya village with the aim of analyzing the relationship between flow discharge and suspension discharge, and analyzing the total amount of suspension load. The method used in this study is a survey method and field measurements in the form of measuring river water level, flow discharge, and taking suspension samples. sedimentation samples were analyzed in the laboratory to determine the concentration of the suspension. The results showed 1) The relationship between flow discharge and suspension discharge had a strong correlation, but did not have a large effect. 2) Rainfall does not directly affect the amount of suspension discharge. 3) The total amount of suspended cargo flowing through the estuary reaches 218,560 tons/year. Keywords : Flow discharge, Suspension sediment, River

Abstract

This study aims to determine the effect of variations in contact time on decreasing levels of Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) using Ozone Microbubble and determine the efficiency level of Ozone Microbubble. This research uses liquid waste from WWTP at PT. Chemical Industry Cikarang with variations in processing time of 20, 40, 60 minutes. The test results before the Ozone Microbubble method was applied did not meet the quality standards and after being applied with a time variation of 20, 40, 60 minutes, they met the Hyundai Industrial Estate wastewater quality standards. The decrease for COD levels with a time of 60 minutes was 614.6 mg/L. Meanwhile, the TSS level is 170.8 mg/L. Both still meet the quality standards of the Hyundai Industrial Estate. The efficiency level for COD is 33% and TSS is 32%. From the results of reducing COD and TSS, it can be concluded that the use of Ozone Microbubble can be used in chemical waste. In addition to the relatively high percentage of reduction, in terms of costs in this research, it is also relatively cheap and can be a proposed idea if it is to be implemented.

Abstract

The problem of waste will be more complex with the increase in population and since a few decades ago changes in consumption patterns and people's lifestyles have resulted in an increase in the amount of waste generation. Yogyakarta has a tourist village that is engaged in the environmental sector, to be precise, Dukuh Sukunan, Banyurraden Village, Gamping District, Sleman Regency, DIY. Glass waste is a waste that is mostly generated from people's lives, especially in big cities such as Yogyakarta and other cities. Most of the glass waste is directly dumped into open land, this of course will pollute the environment considering that glass is a sharp object that is difficult to decipher. One of the efforts to utilize this waste is as a substitute material for the brick mixture. Glass powder/glass powder has pozzolandic properties so that it can function as a substitute for cement and filler. The purpose of this study was to determine the general description of the use of glass waste into bricks, the quality of bricks, and the benefits of bricks for local residents. The method used is descriptive. Production of bricks in the village-scale Sukunan tourism village using a semi-manual method, the size of the bricks is 20x10x5 cm. brick quality according to SNI-03-0348-1989 standard. Brick with the age of 3 days is included in the class III category, which is 40 kg 7 days and 14 days is included in the class II category, which is 79 kg, while the bricks aged 21 and 28 are included in the class I category with the provisions of 100 kg and the compressive strength of the bricks is age 21 and 28 days are 102 kg and 112 kg (Rachaman, 2021). Brick is used commercially and socially. Keywords: Waste Glass, Tourist Village, Brick

Abstract

According to the DKI Jakarta Provincial Environment Agency, in 2016 the average waste entering the Bantargebang TPST reached 6,562 tons/day. The composition of the waste consists of 54% organic waste, 15% paper waste, 14% plastic waste, and others reaching 17% (DKI Jakarta Provincial Environmental Service, 2018). LDPE plastic is a waste that cannot be decomposed by the soil so that its presence in the environment becomes a pollutant. One of the uses of LDPE plastic waste is to change its shape into coarse aggregate for the manufacture of paving blocks. The use of plastic waste is also expected to be able to overcome the problem of using single-use plastics in Indonesia. Quantitative methods in this study were used to determine the quality produced from the process of making paving blocks based on quality standards for compressive strength of paving blocks according to SNI 03-0691-1996. The composition ratios used in this study were 0%, 10%, 20% and 30%. Then the compressive strength and flexural strength were tested for each paving block composition. Based on the results of Mexindo's structural and material laboratory tests. Paving with a mixture of 30% plastic with 28 days of age had good results, namely 26.54 MPa, while paving with a mixture of 10% and 20% plastic had smaller yields of 10.21 Mpa and 8.84 Mpa, but based on SNI on concrete bricks, paving with The plastic aggregate mixture is included in the quality category C. For this flexural strength test, the researcher only compares paving without plastic and paving with plastic mixture, because there is no SNI for the flexural strength of paving. Based on the results of the LDPE Plastic test, aggregates can be made. The results of the compressive strength test of paving with a plastic mixture have good results and enter category C according to SNI. For flexural strength with a mixture of plastics, the results are quite good and are equivalent to those on the market. Based on the quality requirements above, all paving blocks have not passed the test because they have not fulfilled part of the test, namely the water absorption test.

Abstract

Waste is still a serious problem in Indonesia. How to manage waste in the community environment refers to the end of pipe method (final approach). Waste management with the end of pipe method can be replaced in a new way, namely by managing waste earlier. Eco enzyme or eco enzyme in Indonesian is a solution of complex organic substances produced from the fermentation process of organic waste, sugars, and water. Waste processing with the Eco enzyme method uses the fermentation method (Bernadin, Desmintari, and Yuhanijaya 2017). This eco enzyme is made with the basic ingredients of kitchen waste which includes fruit and vegetable skins and then mixed with brown sugar (mollase) and water in a ratio of 3: 1: 10. In this study, there were five Eco Enzyme variables with different compositions, namely by using banana peel components, dragon fruit peels, potatoes, corn, and carrots. The results showed that the fermentation of eco enzyme solutions made from banana peels, dragon fruit peels, potatoes, corn, and carrots had acidic properties with a pH of 3.5, TDS 1460, and a moisture content of 93%. Visually, the resulting solution is brownish in color, the smell smells freshly typical of fermented aromas, and is produced by mama enzymes in eco enzymes, as well as the absence of contamination such as insects or other animals.

Abstract

Plastic litter is an environmental problem at the moment. Today's widely used plastic is a synthetic polymer plastic made from petroleum that is difficult to dissolve in nature. The concrete step needed to address the environmental problem is to use and develop rapidly bioplastik plastic. Bioplastik plastic (bioplastic) is a bioplastik plastic that is bioplastik by microorganisms that break down. In this study the production of a bioplastic is made from durian seed starch. Selection of materials is based on biodegradability in the environment more easily and abundant raw materials available, and lack of innovation in the use of durian waste. Bioplastic production begins with an 2.5 ounce [2.5 g] of durian seed being diluted by 50 ml [50 ml] aqudest, then stirred and heated with 50oC, 60oC, 70oC, 80oCand 90oC, mix kitchambers 1ml and 0.2 - ml glycerol and mix them back for 10 minutes, then pour a bioplastic solution into print, Removing the plastic from the glass plate for characteristic testing. The results of the analysis show that warming temperatures in the gelatinization process affect strong value drag, elongation value and water-resistant value, which, as rising temperature of warming, increases the strong value of drag, elongation value and water resistance. The highest attractive value is found in the 90oCtemperature variation of 54.27 mpa. The highest concentration of elation is 16.4, 10 percent. The best water resistance lies in a 90oCwarming variation of 21.21 % and the fastest minus time of degradation found in a 50oCtemperature variation of 8 days.

Abstract

Among the many issues related to the environment, there are two issues that are currently developing, namely organic fertilizers and the use of organic waste. It is still widely understood that environmental management is still a burden that only wastes the budget. As technology develops, environmental management makes it possible to make profit no longer a burden. Such as the management of organic waste feces, livestock manure, food waste and other organic waste which is processed into biogas and by-product fertilizers in the form of solid fertilizers, liquid fertilizers and even electrical energy. In the Yogyakarta area, there is an environmental tourism village, to be precise, Sukunan Hamlet, Bayuraden Village, Gamping Sleman District, in this area there is a program for raising cows in shared cages where the amount of waste that interferes with health and environmental aesthetics is converted into raw material for making biogas. The management of the cage together had the idea of ​​​​processing biogas from the waste produced by making a biodigerster, from the utilization of biogas, methane gas was produced which can be used directly as fuel in cooking. Methane gas from the biogas process is channeled through pipes connected to a modified gas stove that is adapted to the use of biogas. Cow dung into biogas as an alternative energy creates added value from cow dung in addition to being compost and makes it easier for people to get energy sources, research objectives, methods used and main conclusions from the article.
