Abstract

Industri batik saat ini mengalami pertumbuhan pesat, namun dibalik hal tersebut limbah cair yang dihasilkan semakin banyak terutama akibat pewarnaan. Salah satu pewarna yang dipakai yaitu pewarna organik yang berasal dari campuran pewarna alami dan zat pengikat. Pencampuran mengakibatkan zat pewarna bersifat stabil dan sulit mengendap secara alami. Koagulasi - flokulasi secara mekanis dapat menjadi solusi. Penelitian ini bertujuan untuk mengetahui waktu pengadukan terbaik, desain impeller yang efisien, dan kecepatan putaran impeller yang optimal pada koagulasi – flokulasi untuk menurunkan kandungan limbah cair batik organik. Penelitian dilakukan pada skala batch dengan memvariasikan waktu pengadukan, jenis impeller, dan kecepatan putaran impeller koagulasi – flokulasi. Dari hasil penelitian didapatkan waktu pengadukan terbaik yaitu 21 menit, jenis impeller yang efisien yaitu flat paddle 2 blades angle 30 bertingkat dan kecepatan putaran impeller yang optimal yaitu 100 rpm – 50 rpm. Pada variasi terbaik, efisiensi TSS, COD, warna dan kekeruhan masing-masing sebesar 95,62%, 80,44%, 82,42%, dan 84,38%.

Abstract

The lack of waste management facilities coupled with the amount of waste generation that continues to increase along with the increase in population causes the accumulation of waste at several points in Kesamben District. Most of the people throw their garbage on the side of the road, in the river, or by burning. For this reason, it is necessary to analyze the generation and composition of waste in Kesamben District so that a waste management system can be carried out in accordance with the rules. The research was conducted by measuring waste generation directly from 26 sampling points throughout the Kesamben District. The waste generation sampling procedure was carried out based on SNI 19-3964-1994. From the sampling activity that has been carried out, the resulting solid waste generation is 0.1393 kg/person/day. While the results of the analysis of the composition of the waste showed the types of organic waste, plastic, paper, cloth/textile, glass, Styrofoam, and diapers. With the percentage of waste composition, respectively, that is 64.55%; 19.7%; 8.49%; 1.71%; 0.41%; 0.75%; and 4.38%. From these results it can be concluded that the composition of household waste is dominated by organic waste. So that people should be able to take advantage of composting technology to manage waste in their homes and sort out plastic waste to reduce the amount of waste generated.

Abstract

The generation of waste will increase every year. Therefore, a good waste management system is needed to minimize the negative impact of the waste itself. One of the waste processing is the transportation of waste from TPS to TPA. The generation of waste itself is influenced by the population. The number of residents served by UPTD Tumpang is 542120 people in 2021. The sub-districts served by UPTD Tumpang are Pakis District, Jabung District, Tumpang District, Poncokusumo District, Wajak District and Tajinan District. Garbage collected at TPS as much as 258.6 m/day will be transported to TPA Paras Poncokusumo. The generation of waste that increases every year requires efficient route management and provision of fleets. This study aims to discuss the projected waste generation that will affect fleet requirements and traffic in the next 10 years. Using a dynamic model by utilizing the Stella software, it is possible to find out the needs of the fleet and the flow of waste transportation in the coming year based on waste generation. The results of this research in 2022 in the form of fleet needs as many as 11 units and 36 cycles per day. In the existing condition, there are 10 fleets and 38 rides, so from these differences it can be seen the reduction in distance, fuel costs, and vehicle emissions.

Abstract

Waste processing that is less than optimal causes the generation of large amounts of waste so that action is needed to process it into useful new products, for example into briquettes. The implementation of adding raw materials in making briquettes with waste that has low economic value is expected to improve the quality of briquettes. Paper waste and used cooking oil have the potential to be processed as additional raw materials in the manufacture of briquettes in producing alternative fuels. Based on the results of characteristic testing, the quality of the briquettes increased after the addition of paper waste and used cooking oil. The water content of briquettes from 5,12% decreased to 1 – 2%. The ash content of briquettes from 10,01% decreased to 5 – 7%. The calorific value of briquettes from 4902 cal/g increased to 5200 – 5700 cal/g. The compressive strength of briquettes from 4,38 kg/cm2 increased to 5,51 – 9,48 kg/cm2. The immersion treatment of used cooking oil has an optimum time limit because it can affect the solidity of the charcoal when testing the compressive strength. The addition of paper waste and used cooking oil to the combustion rate increases the combustion power of briquettes and the flame lasts longer so that the combustion rate range obtained is small. The emission of carbon monoxide (CO) produced by the briquettes in this study is relatively low because it is still far below the required quality standards.

Abstract

The average waste generated by the city of Sidoarjo is 1224 tons per day. The composition of plastic waste is 11% and food waste is 70.3%. The production of fuel derived from waste (Refused Derived Fuel / RDF) aims to convert some of the combustible waste in municipal solid waste into fuel. This research is an experimental study to determine the composition and type of the best adhesive made from a mixture of organic and inorganic waste with molasses (molasses), paraffin, and starch adhesives and compared with the existing briquette quality standards. This study analyzed the value of water content, volatile content, ash content, calorific value, and the rate of burning of briquettes using a descriptive method. From the research results, it is known that paraffin has a higher calorific value when compared to starch and molasses. The best calorific value in V3 is a mixture of 40 grams of inorganic waste and 80 grams of organic waste with paraffin adhesive. This composition produces a calorific value of 5218 kcal/kg, 1.04% water content, 17.34% ash content, 7.4% volatile content, and 0.138 gr/sec combustion rate. The value of water content, volatile content, and calorific value meet SNI 01-6235-2000. However, the value of the ash content not fulfilled

Abstract

Batik wastewater comes from the dyeing process of batik fabrics. Reactive dyestuffs are synthetic dyes that are often used. Reactive dyes that are often used are Methyl Orange (MO) and Methyl Blue. Only 5% of the dyestuffs are used in batik dyeing, the remaining 95% will be discarded. The content of dyestuffs used causes batik liquid waste to have alkaline, cardiogenic properties, difficult to decompose and contain high organic substances. So that batik wastewater treatment is needed before it is discharged into water bodies, coagulation is one of the waste treatment methods that can be used. The purpose of this study is to determine the decrease in pollutant parameters in the form of TSS and color by the biocoagulant of dried luffa cylindrica. This study was conducted by varying the dose of coagulants and pH of coagulants with a stirring speed of 200 rpm for 2 minutes and a stirring speed in the flocculation process of 60 rpm with a time of 40 minutes. The highest removal of color content and Total Suspendid Solid (TSS) occurred in the use of biocoagulant at a dose of 3500 mg / l pH 6, namely 76% and 75% respectively.

Abstract

Rivers water resources have characteristics and properties different from other resources, where humans still need water to survive. The rapid growth of the population, especially in urban areas, has a serious impact on the decline in the carrying capacity of the environment. Eco-enzyme produced from simple fermentation of fresh vegetable or fruit waste, brown sugar, and water in a ratio of 1 : 3 : 10 is useful in reducing the level of pollution. Thus, the purpose of this study is to determine the effectiveness of eco-enzyme against the elimination of TSS, TDS, and Surfactant levels in domestic waste. In this study, we used variations in anaerobic processes and coagulation-flocculation with a concentration of eco-enzymes of 7,5% ; 5,0% ; 2,5%. Anaerobic processes take a residence time of 5, 10, 15 days. While the coagulation process – flocculation with 150 rpm on fast stirring for 1 minute, 60 rpm slow stirring for 15 minutes. Eco-fruit enzymes were more effective, the anaerobic process concentration of 5.0% was able to reduce the most optimal pollutant parameters by 8.70% for TSS, 62.42% for TDS, and 7.5% concentration by 98.87% at a stay of 15 days. While the coagulation – flocculation process with a concentration of 2.5% is able to set aside TSS by 7.33%, TDS by 42.07%, and concentration of 7,5% is able to set aside Surfactants by 96.29%.
