Abstract

The heavy metal ion pollution such as lead (Pb2+) in wastewater is an environmental problem that needs to be solved. The adsorption method has been reported to have good potential as an alternative method for reducing heavy metal contents in aquatic environment. The most widely used adsorbent media are porous materials with a large surface area and low density. Metal Organic Frameworks (MOFs) are a type of porous material that is widely applied in various fields, such as fuel purification, solvent recovery, gas storage, and adsorbents. Lead(II) is a heavy metal ion that can pollute the environment and endanger humans. This study aims to synthesize MOFs and apply it to the Pb2+ adsorption process. In this research, MOFs type Zn-BDC or MOF-5 were synthesized by sonochemistry method at 60 ℃ as adsorbent for Pb2+ ion. Characterization of the adsorbent by FTIR showed the presence of functional groups C=O, C-H, and Zn-O which indicated the formation of the MOF-5 compound. The concentrations of Pb2+ ions were analyzed using Atomic Absorption Spectrophotometer (AAS). The experimental results show the optimum conditions for the adsorption process at pH 5 for 60 minutes with adsorption efficiency reaching 93.41%. Testing the adsorption isotherm model showed that the Pb2+ ion adsorption process using Zn-BDC as an adsorbent followed the Langmuir isotherm model with the R2 value of 0.9986.

Abstract

The rapid development of the palm oil industry, which cannot be denied, has an impact on the amount of industrial waste, particularly wastewater, requiring proper and effective treatment to reduce the impact of the damage. Wastewater treatment of Palm Oil Mill Effluent (POME) in an aerobic pond requires an adequate supply of oxygen so that its quality improves and becomes disposable, so it requires assistance from aeration media. A fine bubble diffuser was used as the aeration medium in this study. The aeration medium in this study was a fine bubble diffuser. The purpose of this research is to investigate the impact of installing a diffuser on the quality of the final wastewater, particularly the COD and BOD values, in the palm oil industry wastewater treatment. The analysis results for the wastewater parameters after the installation of the fine bubble diffuser revealed a significant reduction in the waste's COD and BOD values to 130 – 175 mg/L and 67 – 78 mg/L, respectively, making it more suitable for disposal to the environment.

Abstract

Production of acetone-butanol-ethanol (ABE) through the fermentation process is one alternative that needs to be developed. Less economical in the ABE fermentation process is the difficulty of the separation process from the fermentation product and the by-products of the reaction. Among the separation process methods, such as extraction, distillation, adsorption, and gas stripping, the distillation method is still the most widely used method in the ABE separation process. The purpose of this study was to provide recommendations for predicting good ABE separation and producing optimum operating conditions to produce high % butanol content. Which is then simulated using Aspen Plus V11 software. This study varied the reflux ratio in the distillation column and the decanter operating temperature. The results showed that butanol purity reached 90.33% in the radfrac 1 column operated at a pressure of 1.3 atm with a reflux ratio of 5, the location of the 7th feed stage and the number of stages 11. Then proceed to the purification stage in the radfrac column 2 which is operated at a pressure of 2 atm with a reflux ratio of 5, the location of the 4th stage feed and the number of stages 5. The decrease in the reflux ratio of the radfrac column causes a decrease in the butanol content at the bottom so that the purity of butanol also decreases and decreases % recovery or recovery of butanol. This is also followed by the location of the feed stage, which is getting higher, and the number of stages is increasing.

Abstract

Oil palm empty fruit bunch (EFB) is one of the biomass wastes that have a great potential of a bioenergy resource due to its natural properties, such as high calorific value. The conversion of EFB biomass into valuable biofuels can achieved through biochemical and thermochemical processes. Tar (bio-oil), the liquid product from the pyrolysis is one of the most attractive biofuels. The study aims to determine the effect of temperature process of pyrolysis EFB on its tar production under droptube reactor. The results showed that maximum tar yield was 43,80% obtained at 500 °C. The EFB tar produced at 500 °C was also determined to have a higher of phenol compound at 51,9%. The high phenolic content indicates its potential to be used for the production of renewable phenolic resins. Hence, the present work of pyrolysis of EFB presents itself as a promising method to produce phenol rich tar (bio-oil) from biomass waste.

Abstract

Banana is one of the fruits that can thrive in Indonesia. This plant is often found in tropical soils with slightly moist soil conditions. However, banana peels are underutilized and are only disposed of as agricultural waste. On the other hand, the carbohydrate content of banana peels is still quite high, reaching 12.2% so it can be used as raw material for making bioethanol. Carbohydrates in the substrate cannot be directly converted into bioethanol but need to be pretreated first to break down polysaccharides into monosaccharides. In this research, the pretreatment process of carbohydrate hydrolysis from banana peels into reducing sugars is studied. From the studies, the reducing sugar concentration was obtained with banana peels substrate concentration of 20 g/L, 5 M of sulfuric acid concentration, and an optimum hydrolysis time of 70 minutes with the obtained reducing sugar reach 16.82 g/L. Reducing sugar can be converted into bioethanol by fermentation process with S. cerevisiae yeast. It is hoped that these studies can provide an initial impact on the development of alternative energy based on biomass and utilization of banana peel waste.

Abstract

Floor cleaning products on the market usually use synthetic active that can interfere with health and the environment. Therefore, highly recommended to substitute synthetic active with natural active substances such as essential oils. The by-product of essential oils is hydrosol which is also not safe for the environment. This research aims to analyze hydrosol's effectiveness as an antibacterial and get an optimal formulation of oil essential and hydrosol as antibacterial in floor cleaning products. Kaffir lime leaf oil, lemongrass oil, and its hydrosol have been used as an additive in floor cleaners. pH value, free alkaline level, viscosities, and antibacterial effectiveness have been analyzed for floor cleaning products produced in this research. This research found a pH value of 6-8, viscosities is 1516-1867 cP, and free alkaline level of 0,1519-0,1627 b/b. The most antibacterial effectiveness found in the composition of kaffir lime leaf oil and its hydrosol is 15% and 30%, have bacteria inhibition of 10 mm. pH value, free alkaline, and viscosities have been fulfilled the standard of SNI 1842:2019.
