Abstract

The decaffeination of robusta coffee can be done through fermentation with a crude enzyme containing bromelain enzyme from pineapple. The study aims to determine the activity of the bromelain enzyme by the Kunitz method, the effect of fermentation time and crude enzyme concentration on the decaffeination process, and the characteristics of coffee before and after fermentation using FTIR. The fermentation time was varied from 6 to 36 hours and the crude enzyme concentration was varied from 10 to 80%. The activity of the bromelain enzyme was 36 U/ml. Fermentation time affects the decaffeination process, wherein the longer the fermentation time from 6 hours to 36 hours obtained caffeine content from 2.39% to 0.07%. Besides that, the crude enzyme concentration affects the decaffeination process, which obtained the lowest caffeine content or percent decaffeination at the crude extract concentration of 80% (v/v). FTIR results showed that the decaffeination process affected the reduction of caffeine in coffee samples. It can be shown from the increase in the %T value of the C-N functional group from 40.731 to 54.85.

Abstract

The tofu industry produces liquid waste containing high organic compounds. Organic compounds in liquid waste can threaten aquatic ecosystems if discharged directly into water bodies. One of the most effective wastewater treatment systems is the treatment using Anaerobic Sequencing Batch Reactor (ASBR). Besides being able to reduce the content of organic compounds, ASBR can produce biogas, and its decomposing microorganisms do not flow into the effluent stream. The purpose of this study was to evaluate the performance of ASBR at an effective reactor volume according to the design. This is because the use of ASBR in previous studies had not reached the operational stage and did not use an effective volume reactor. The stages of waste treatment using ASBR include the seeding, acclimatization, and operation stages. Waste treatment took place at room temperature in the reactor with an effective volume of 6 L. The operating parameters tested were MLVSS, COD, BOD, pH, and cumulative biogas volume. The results obtained show that the seeding process took 56 days, acclimatization took 10 days, and the operation lasted for 17 days. The efficiency of reducing COD concentration was 60%, the efficiency of reducing BOD concentration was 35.65%, and the cumulative volume of biogas produced was 24,120 mL at the operating stage. The use of the ASBR system at an effective volume of 6 L resulted in the successful processing of tofu liquid waste.

Abstract

Ion exchange is one of the water treatment methods used to reduce hardness. To improve the performance of the ion exchange columns, modification can be done by adding an activated carbon column placed after the ion exchange column to adsorb ions that were not exchanged by the resin so that the treated water met boiler feed water quality standards. The purposes of this study were to determine the best flow rate to reduce hardness in the configuration of the ion exchange and activated carbon columns, determine the saturation time of each column, and determine their exchange/adsorption capacities. The steps of this study included modifications and repair of equipment, leak tests, and configuration system performance tests. Performance tests were conducted by varying the feed flow rates by 0.2; 0.4; 0.6; 0.8; 1 GPM and analyzed the efficiency of hardness reduction. The results of this study showed that the best flow rate to reduce the initial hardness of 499 mg/ L CaCO3 was a flow rate of 0.6 GPM or 2.2 LPM. The efficiency of hardness reduction in the configuration system was 100%. The conductivity of the effluent of anion column and activated carbon column decreased compared to the conductivity of the effluent of cation column with an average decrease of 33.17% in the anion column and 18.35% in the activated carbon column. The saturation time of the configuration system was 168 minutes in cation resin, 46.4 minutes in anion resin, and 159 minutes in activated carbon. Furthermore, the adsorption capacity of cation resin, anion resin, and activated carbon were 35.28 mg/g, 43.98 mg/g, and 9.61 mg/g, respectively. The addition of activated carbon in the configuration system lowers the conductivity of the effluent and decreases hardness.

Abstract

Metallic corrosion, the deterioration process induced by the interaction between metals and corrosive environments, poses a significant challenge to material integrity and longevity. Corrosion inhibitors have been identified as an effective approach among various mitigation strategies. Natural extracts, such as those derived from turmeric/Curcuma longa, have garnered attention for their potential as eco-friendly corrosion inhibitors. This study endeavors to extract, characterize, and evaluate turmeric extract's efficacy as a corrosion inhibitor within a 30% acetic acid solution. Employing microwave-assisted extraction with a 96% ethanol solvent facilitated the isolation of the extract, which was subsequently subjected to qualitative analysis through phytochemical screenings and Gas Chromatography-Mass Spectrometry (GC-MS). These analyses confirmed the presence of antioxidative phytochemicals, including alkaloids, terpenoids, turmeronoids, curcumin, sesquiterpenoids, and phenols. The corrosion inhibitory properties of turmeric extract were assessed via immersion and flow loop experiments, revealing a notable reduction in corrosion rates—from 0.1540 mm/year to 0.0801 mm/year in immersion tests and from 5.3747 mm/year to 2.9369 mm/year in flow loop tests. Such outcomes underscore turmeric extract's potential as a viable corrosion inhibitor, attributed primarily to the chemical interactions facilitated by curcumin's phenolic and carbonyl groups with the metal surface, thereby enhancing protective efficacy. The inhibitor efficiency was quantified at 47.9743% and 45.3565% for immersion and flow loop tests, highlighting the extract's substantial inhibitory performance.

Abstract

Methylene blue is a material that is often used as a cationic dye in the textile industry. Methylene blue is toxic and difficult to degrade. Adsorption is one method to reduce the methylene blue from wastewater. In this study, methylene blue was adsorbed by calcium alginate/activated carbon composite (CaAlg-AcC) in a fixed bed column. The influence of CaCl2.2H2O concentration, initial concentration of methylene blue, and flow rate in the continuous adsorption process were investigated. Every adsorption process was done in 110 min. The results revealed that the CaAlg-AcC composite synthesized using 1% (w/v) CaCl2.2H2O solution has the highest adsorption percentage, 95.28% in 110 min. The initial methylene blue concentration 50 mg/L gave the highest result of adsorption percentage with the smallest amount of methylene blue adsorbed of 31.77 mg.  The flow rate of methylene blue 4 ml/min reached the highest adsorption percentage with the amount of methylene blue adsorbed of 41.79 mg.

Abstract

Methylene blue adsorption research has been conducted using bioadsorbents from activated carbon of coffee grounds and reeds. Coffee grounds and reeds contain carbon and cellulose that are effective for binding dyes. This study aims to determine the characteristics of activated carbon from coffee grounds and reeds based on SNI-06-3730-1995 and assess the color reduction of wastewater referring to the Decree of the Minister of Environment No. 51/MENLH/1995, which sets the maximum methylene blue content in industrial wastewater at 5-10 mg/L. The research method includes bioadsorbent preparation, characterization, and adsorption process with UV-Vis spectrophotometric analysis. Mass ratio variation was conducted on each adsorbent at each contact time variation and methylene blue concentration variation. The results of the analysis showed that the activated carbon of coffee grounds and reeds fulfills SNI-06-3730-1995 which is characterized by values that are below the maximum value in each parameter. The effectiveness of methylene blue adsorption by coffee grounds and reeds activated carbon reached 98.15% at a ratio of coffee grounds and reeds activated carbon 0:1 (w/w) for 120 minutes at a concentration of 25 mg/L. The adsorption capacity using the Freundlich isotherm method on reed activated carbon was 1.100 mg/g and coffee grounds activated carbon was 1.019 mg/g. The adsorption process of coffee grounds and reeds activated carbon has no effect on the carbon and cellulose structure of coffee grounds and reeds contained in activated carbon, namely O-H, C-H, C=C, and C=O.
