Abstract

Oil content in the water that exceeds the threshold can pollute the environment if disposed of directly without waste treatment. This study conducted a case study of engineering waste treatment containing 1% oil using the Dissolve Air Flotation (DAF) method through coagulant and flocculant pre-treatment. The independent variable used in this study is pressure and residence time, where the pressure variable consists of 0.6, 0.8, 1, 1.2, and 1.4 bar, while the residence time variables comprised 5, 15, 30, 45, and 60 minutes. This study obtained the maximum pressure and residence time, namely at a pressure of 1.4 bar and a residence time of 60 minutes; the highest oil removal was 98.32%. Turbidity removal was 92.31% in 1% of engineering waste for engineering destruction.

Abstract

At the end of 2019, the COVID-19 pandemic hit the world, which had several effects on various sectors, one of which made several industrial sectors suffer heavy losses and even bankruptcy. The industrial sector needs household goods, such as soap and detergent, among the most needed items during the Covid-19 pandemic. To produce these hygiene items, the industrial sector requires various raw materials, one of which is Sodium sulfate (Na2SO4). Sodium sulfate is processed using the Mannheim process through reaction, crystallization, and drying stages. The designer plans to build a plant with a capacity of 20,000 tons/year in the industrial area of Lamongan, East Java. The raw materials used consist of sulfuric acid and sodium chloride. The utility unit consists of a water supply unit, steam supply unit, power generation unit, fuel supply unit, and cooling supply unit. The company's business entity is a Limited Liability Company (PT) using a line and staff organizational structure with 150 employees. The employee work system is based on the division of working hours consisting of shift and non-shift employees. The researchers produced several results of economicanalysis: Fixed Capital Investment (FCI) value of Rp. 195,180,724,917, Working Capital Investment (WCI) value of Rp. 34,443,657,338, Total Cost Investment (TCI) value of Rp. 229,624,382. 255, then the Total Product Cost (TPC) value is Rp. 441,103,560,855, and the Total Sale (TS) value is Rp. 522,048,972,696, Internal Rate of Return (IRR) of 35.98%, Pay Out Time (POT) for 3.15 years, and Break-Even Point (BEP) value of 36.40%. Based on the above evaluation results, the Sodium sulfate decahydrate plant from Sulfuric acid and Sodium chloride by Mannheim process is feasible.

Abstract

Glucitol is the result of glucose reduction by changing the aldehyde group to a hydroxyl group, hence the name sugar alcohol. Sugar substitute sweeteners have various requirements, namely having a sweet taste, not causing toxicity to the body, calorie, and can be produced in large capacities. The most relevant sugar substitute with these criteria is glucitol. Glucitol factory is planned to be established in Jombang Regency, East Java with a production capacity of 20,000 tons/year. The raw material used in this glucitol factory is using tapioca starch raw material with a catalytic hydrogenation process. In the manufacture of glucitol there are 2 important processes, namely, the first process converts strach into glucose or dextrose with supporting raw materials for amylase enzymes and glucoamylase enzymes in the main tool, namely the reactor. In the catalytic hydrogenation process glucose or dextrose is reacted with hydrogen gas at high temperature and pressure with the help of the addition of nickel raney catalyst. The resulting glucitol is then purified in the evaporator to produce 70% glucitol. In the design of the Glucitol factory requires a total capital investment of Rp. 197,294,444,028 The total production cost of this factory is Rp. 552,393,444,402 with annual sales of Rp. 800,000,000,000. From the economic analysis, BEP was obtained at 23.7% with POT for 2.122 years and IRR of 64.14%. In terms of engineering and economics, this plant is feasible to establish

Abstract

Liquid waste has a component containing water that has been mixed with chemical compounds. One example of liquid waste containing chemical compounds is wastewater from a food coloring industry. The liquid waste of the food coloring industry has a very strong color density so that it has a negative impact on the environment, therefore it is necessary to treat liquid waste in order to meet the quality standards of wastewater in accordance with East Java Governor Regulation number 72 of 2013. The purpose of this study was to determine the effect of adding dose of coagulant and mass of biosorbent on percent color removal in food coloring industrial wastewater. The results showed that the addition of 35% coagulant and 13% biosorbent resulted in 97% optimal removal of color.

Abstract

Sodium carbonate, commonly known as soda ash, is a chemical compound with the formula Na₂CO₃. It plays a vital role in various industries as a pH regulator in chemical processes, an electrolyte in reactions, and a fluxing agent to lower the melting point in glass production. Despite its wide industrial use, Indonesia currently has no domestic sodium carbonate production facilities, resulting in a growing dependence on imports to meet increasing demand. This preliminary plant design proposes the production of sodium carbonate using the carbonation method, with sodium hydroxide and flue gas waste from coal-fired power plant as raw materials. The process involves reacting NaOH with CO₂ extracted from flue gas in a reactor to form sodium carbonate. The product is then concentrated through evaporation, crystallized into wet crystals, and dried using a rotary dryer. The final stage involves adjusting particle size to meet market specifications for the Na₂CO₃ product. Economic analysis indicates that the plant is financially viable, with an Internal Rate of Return (IRR) of 23%, a Pay Out Time (POT) of 3.8 years, and a Break Even Point (BEP) of 27.28%. In conclusion, establishing a sodium carbonate plant using flue gas waste from the coal-fired power plant with a production capacity of 350,000 tons per year is considered economically feasible.

Abstract

The electroplating industry is one of the producers of liquid waste containing lead heavy metal (Pb(II)) which is a high risk to the environment and human health. Pb(II) metal is a toxic heavy metal, does not decompose easily, is bioaccumulative, and its solubility is strongly influenced by pH. In acidic conditions, Pb is more easily soluble as Pb²⁺ ions, in alkaline conditions it can form deposits such as Pb(OH)₂. Based on its toxic and persistent nature, Pb needs to be treated before wastewater is discharged into the environment. This study aims to process electroplating liquid waste through the development of magnetic activated carbon based on breadfruit bark synthesized using the precipitation method, as well as to examine the effectiveness of its application in the removal of Pb(II) ions from electroplating liquid waste. The characterization of magnetic activated carbon as an adsorbent is carried out using various analysis techniques to determine the surface morphology, pore structure, and specific surface area. Adsorption tests were performed to evaluate the effect of contact time, and adsorbent dose on Pb(II) removal. The results showed that magnetic activated carbon has a high ability to absorb Pb(II), with a removal of 96.79%. the optimal conditions were obtained at an adsorbent mass of 3.424 g and a contact time of 79.137 minutes, with a prediction of Pb(II) removal of 98.083%
