Abstract

Industrial processes that discharge heavy metals into the environment are a growing environmental crisis because of the dangers they pose to aquatic life and human health. Nickel (Ni) is one of the most dangerous metals due to its extreme toxicity and its ability to bioaccumulate in food chains. Severe health complications may develop from chronic exposure to nickel. Chemical precipitation, ion exchange, and reverse osmosis are traditional methods used to remove Ni(II) ions from wastewater. Nonetheless, these approaches have drawbacks, such as elevated operational costs, excessive chemical consumption, and inefficiency in treating low-concentration wastewater. The effectiveness of solvothermally synthesised chitosan as an adsorbent for the removal of Ni(II) ions from aqueous solutions was examined in this work. Acidity, adsorbent concentration, and contact duration were all carefully measured and analyzed. Optimal adsorption occurred at pH 6, yielding a maximum removal effectiveness of 75% after 75 minutes of contact. An adsorption efficiency of 54.69% was achieved with the optimal adsorbent dose of 0.4 g. Kinetic analysis indicated that the adsorption process followed the Pseudo-Second-Order (PSO) model, with a correlation coefficient (R²) of 0.999, suggesting that chemisorption prevailed via interactions between Ni(II) ions and the –NH? and –OH functional groups on the chitosan surface. The solvothermal modification improved the adsorption capability of the chitosan by increasing its surface area, porosity, and number of active sites.

Abstract

Cajuput oil is an essential oil of high economic value and is widely used in the pharmaceutical and health industries. However, national production remains suboptimal, partly due to the low 1,8-cineole content. This study aims to compare improvements in cajuput oil quality achieved through laboratory-scale and pilot-scale redistillation processes. Redistillation was applied to cajuput oil obtained from the initial distillation, using young leaves, mature leaves, and mixed leaves as raw materials. The evaluation included organoleptic characteristics, refractive index, and 1,8-cineole content determined by GC–MS analysis. The results indicate that the highest 1,8-cineole content was achieved by redistilling young leaves, reaching 83.84%, and all distillates complied with the quality standards specified in SNI 3954:2014. The re-distillation process was proven to enhance color clarity, aroma, and chemical quality of cajuput oil. Therefore, redistillation shows strong potential for application at the production scale to support the development of high-quality cajuput oil using green technology.

Abstract

Biomass characterisation is important for knowing the contained components in biomass. Some types of biomass studied were wood of acacia (Acacia mangium), gamal (Gliricidia sepium), coconut shell (Cocos nucifera) charcoal, and wood charcoal, for the gasification process through proximate analysis, ultimate analysis, and determination of high heating value (HHV). Ultimate analysis data utilised thermogravimetric analysis (TGA) for efficiency. The characterisation results show that coconut shell charcoal and wood charcoal have the highest fixed carbon content (72.66% and 68.98%) and higher C element (57.87% and 54.94%) as well as lower ash content compared to acacia wood and gamal wood, resulting in the highest calorific value (30.01 and 22.05 mJ/kg) and potentially better gasification performance. Conversely, acacia wood and gamal wood show relatively higher volatile matter content (64.03% and 76.38%) and ash (18.88%), resulting in lower calorific values. Overall, the research results indicate that coconut shell charcoal and wood charcoal are more recommended as the primary fuel in the gasification system.

Abstract

Paper waste is a potential solid waste. Cellulose, which is the largest component of paper waste, consists of glucose monomers that can be obtained through the hydrolysis process. In this study, hydrolysis process and kinetic evaluation of paper waste in a fed batch method using sulfuric acid catalyst was investigated. The results showed that the highest conversion of paper waste hydrolysis was obtained when feeding the paper waste reactant in a fed batch of 2 grams with 90 minutes reaction time. Higher hydrolysis temperature and time produced higher conversion which the highest conversion was 19.083% at 90oC reaction temperature and 90 minutes of reaction. The activation energy produced in the fed batch hydrolysis process of paper waste using sulfuric acid was 422.526 kJ/mol. The application of fed batch hydrolysis method in this study affects the conversion and kinetics value of paper waste acid hydrolysis using sulfuric acid catalyst. The addition of reactants in a fed batch can increase the number of reactant particles and the potential for effective collisions, resulting in faster reaction rate.   ABSTRAK (Bahasa Indonesia) Limbah kertas merupakan limbah padat potensial yang cukup banyak mencemari lingkungan.

Abstract

The increase in waste production, along with population growth, is filling landfills. Organic waste leachate formation. Leachate management is crucial because it can pollute soil, surface water, and groundwater. Waste is the solid remains of human activities and natural processes. Waste will be processed at the final processing site. Waste produces leachate due to decomposition and rainwater infiltration. Leachate testing requires laboratory analysis. Analysis can be done by measuring the physical and chemical parameters contained in leachate. Response Surface Methodology (RSM) is a statistical method for analysing data. This study determines the correlation between the main pollutant parameters, Temperature, pH, total suspended solids (TSS), and COD at the final treatment site. Data were collected from several sampling points over a period, and statistical analyses, including Pearson correlation and regression, were used to assess the relationship. The results showed a significant positive correlation with COD. The COD coefficient of determination (R-squared) of 66.74% was found to be quite high for all functional relationships, and mathematical models have been obtained.
