Abstract

The wound healing process requires an environment that can maintain moisture, absorb excess exudate, and is biodegradable. Conventional wound dressings such as cotton, gauze, and bandages cause wound dehydration. Bacterial cellulose derived from the fermentation of coconut water by Acetobacter xylinum bacteria has unique characteristics that have the potential to be an ideal wound dressing because it can provide a moist environment. It also has good mechanical properties, biodegradability, high biocompatibility, and is non-toxic. Bacterial cellulose produces fine fibres forming a thin layer of extracellular polysaccharides. Such fibre makes it possible to bind to the molecules of the drug. This research will study the mechanical properties and efficiency of drug mass transfer from bacterial cellulose membranes with different carbon sources, namely glucose and fructose, with fermentation time variations of 3, 5, and 7 days. The results showed that the characteristic value of the fructose carbon source was superior to that of glucose. The glucose carbon source has a membrane thickness of 0.81; 6,93; 10.61 mm; fructose is 2.80; 8,41; 13.40 mm. The highest absorption capacity, stress, elongation and drug mass efficiency value is obtained by a fructose carbon source with a fermentation time of 7 days, and for absorption capacity obtained at 1.1640 g/g, stress value 105.9 N with elongation 19.90 mm and drug mass efficiency 4.085%

Abstract

The increasing use of electric vehicles in the coming decades makes the recycling of spent li-ion batteries an important topic to develop. Recycling spent li-ion batteries is necessary to extract valuable materials from the battery cathode. Elutriation is one of the separation method to separate the cathode and anode from the blackmass resulting from crushing by utilizing differences in density and terminal velocity. The Elutriation method is attractive to develop because the separation is done by adjusting the fluid velocity and does not use chemicals. In this study, 4 variations of fluid load will be used, namely 24, 27, 30, and 34 mL/min. The blackmass to be elutriated has a size variation between -38 to +53 micrometers. From the results under the elutriator, the cathode mass obtained for fluid load variations of 24, 27, 30, and 34 mL/min are 0.8366, 0.4333, 0.3907, and 0.1349 grams. The highest cathode recovery at a load of 24 mL/min is 97.21% and the cathode fraction is 0.4091. Furthermore, it can increase the cathode composition in the mixture by 48.98% and reduce the anode composition by 18.54%.

Abstract

Biofuel is a promising alternative as a sustainable energy resource in the transportation sector in Indonesia. Green diesel is one of biofuels that can be produced from feedstock containing fatty acid. Fatty acid conversion to green diesel can be conducted via hydrodecarboxylation or hydrodeoxygenation process. Catalyst Ni/H-ZSM-5 is a potential catalyst to convert fatty acid to n-alkane which is the main component in green diesel. In this work, we prepared Ni/H-ZSM-5 catalyst with various Ni loading of 7%, 13%, 18%, and 25%, respectively. The catalysts were synthesized according to a simple incipient wetness impregnation method. Those catalysts were characterized with X-ray fluorescence, Field-Emission Scanning Electron Microscopy, and NH3-TPD. The highest nickel-loading catalyst, Ni 25%/H-ZSM-5, gave the best dispersion. NH3-TPD results showed the presence of two acid sites, namely Brønsted acid site and Lewis acid site. The presence of Brønsted acid sites is crucial to facilitate fatty acid conversion to n-alkane.

Abstract

Citronella oil residue is one of the abundant lignocellulosic biomass wastes which has the potential to be converted into useful products through pyrolysis process. One of the useful products that can be produced from this residue is furfural compounds. Previous research has shown that furfural can be produced through the pyrolysis mechanism of lignocellulosic biomass. However, the amount of furfural compounds obtained is still relatively low. Therefore, in this study a research is carried out regarding catalytic pyrolysis process through impregnation method of biomass using boric acid as catalyst to produce furfural compounds with variation of catalyst ratio (0, 0.1, 0.3) and pyrolysis temperature (450 oC, 500 oC, 550 oC) to determine the optimal conditions for furfural production. Using GC-MS analysis, results were obtained which indicated the role of boric acid impregnation in increasing and maximizing the yield of furfural products. The optimal conditions for furfural production were obtained at a pyrolysis temperature of 550 oC and the use of a boric acid catalyst with a ratio of 0.1, whereby the yield of furfural compounds by GCMS analysis was 19.17% area.

Abstract

The increase in Indonesia's BTX chemical production was carried out to keep pace with global demand trends. The raw material for alternative production is household waste in Indonesia, of which 36% is plastic. Polyolefins make up 76% of the composition of household plastic waste. The rapidly developed BTX production process is the depolymerization of polyolefin plastics by pyrolysis and catalyst modification for catalysis. Polyolefin plastic in the form of polyethylene produces the highest aromatic yield and selectivity among other types of plastic in plastic waste. This study compared two scenarios with the highest yield of aromatics using different catalysts as base literature with an additional overview regarding the topic related. The process scenarios being compared are polyethylene pyrolysis over CaO with Ga/ZSM-5 catalyst and Zn-ZSM-5 catalyst. Literature overview obtained the overall BTX production progress over time and the potential of polyethylene catalytic pyrolysis for further study

Abstract

The quality of drinking water can be assessed based on three aspects: physical, chemical, and microbiological aspects. One of the chemical aspects in determining water quality is the sulfate content. UV-Vis spectrophotometry method has been widely used to analyze sulfate content. UV-Vis spectrophotometry is a spectroscopic analysis technique that uses an electromagnetic wave source with ultraviolet (UV) for wavelength (190-380 nm) and visible light with wavelength (380-780 nm). The purpose of this study is to determine the absorbance and concentration of samples using spectrophotometric analysis, calculate the sulfate content in the samples, and compare it with the Indonesian Ministry of Health Regulation Permenkes RI No. 32//2017. The research stages include calibration, calibration curve creation, making standard H2SO4 solutions, measuring the absorbance of the standard solutions, and analyzing the sulfate content in water samples. The research results showed that the sulfate concentration in the Bangkalan, Nginden, Sidoarjo, Keputih, and Kapas Madya well water samples were 14.0817, 27.551, 29.1837, 49.0817, 54.6939 ppm, respectively. Based on the Indonesian Ministry of Health Regulation Permenkes RI No. 32//2017, the maximum sulfate content in water is 400 mg/L, thus it can be concluded that the water samples in those areas have met the clean water standards.

Abstract

The use of disposable face masks during the Covid-19 pandemic has resulted in the emergence of mask waste polluting aquatic environments due to poor management. This waste will decompose into microfibers which accumulate in aquatic organisms. The combination of vermiremediation with the addition of degrading microorganisms can be one of the solutions for treating disposable mask waste. In this study, Eudrilus eugeniae, an earthworm species, was used in vermiremediation with variations in the treatment by adding indigenous bacterial isolate from the waters of Lampung Bay which has been proven able to degrade disposable masks. The results showed that the vermiremediation technique can be used to degrade disposable masks, indicated by a decrease in mask weight after incubation for two months in the amount of 0.03 grams and 0.05 grams for the treatment with the Eudrilus eugeniae and a combination of bacterial isolate respectively against the initial weight. Lampung Bay indigenous bacterial isolate helped accelerate the mask degradation process in the combined vermiremediation technique. The carbon, nitrogen, phosphorus, and potassium contents of the compost produced by the vermiremediation process have met the SNI for compost from domestic organic waste.

Abstract

Nanoparticle technology has been widely used in various industries because of its advantages in particle size control systems. One example of the use of nanoparticle technology is copper nanoparticles as an antibacterial material. This research focuses on the utilization of leaching waste as a material for the synthesis of copper nanoparticles. The synthesis of copper nanoparticles was carried out by chemical reduction method between chalcopyrite stone leaching waste namely CuSO4 as precursor, Cetyl Trimethyl Ammonium Bromide (CTAB) as surfactant and NaBH4 reducing agent. The synthesized material will be analyzed using UV-Vis spectroscopy. Furthermore, the particle size will be estimated using PSA and its antibacterial properties will be analyzed using the well diffusion method by looking at the effectiveness of the inhibitory power against Escherichia coli FNCC 0049 and Staphylococcus bacteria aureus FNCC 0047. The results of the synthesis obtained the smallest size of 235.7 nm from the ratio of precursor concentration, reducing agent concentration and, a surfactant concentration of 1:20:8. The results of the synthesis of copper nanoparticles with concentrations of 10.000 ppm showed the presence of inhibitory power to overcome Escherichia coli FNCC 0049 and Staphylococcus bacteria aureus FNCC 0047.

Abstract

The depletion of fossil fuels has led to a turn toward renewable and cleaner diesel fuel. In recent years, research has focused on the development of green energy to replace fossil fuels. 3-Pentanol is the preferred alternative fuel because it has better fuel properties compared to other biofuels. 3-Pentanol, as a propionic acid derivative chemical platform, can be produced from renewable biomass through the lactic acid pathway. Therefore, to obtain 3-Pentanol with high purity, a purification process such as distillation is required. Vapor-liquid equilibrium data and the thermodynamic model parameters are needed as basis for designing a distillation column and optimizing the separation process. The aim of this study is to predict the vapor-liquid equilibria (VLE) of the binary systems of 3-Pentanol + propionic acid at 100 kPa, 200 kPa, and 300 kPa using the UNIFAC model in combination with the Hayden-O’Connell model. The prediction results showed no azeotropes found for the studied systems. This study can also open a scope for the thermodynamic studies of biofuel separation process.
