Abstract

Oxygen is used in various chemical processes and medical purposes around the world. During the COVID-19 pandemic, the need for medical oxygen has increased sharply in all hospitals in the world. In the current work, we designed anoxygen concentrator by using the Pressure Swing Adsorption (PSA)technology. Efficient operation of the PSA process is required to utilize the adsorbent capacity as much as possible and reduce the processing power requirements. The effect of feed gas temperature, cycle time, and pressure were investigated.  The research is expected to provide suitable operating conditions to develop a better PSA process using zeolite Na-X.

Abstract

Managing wastewater from dyeing industries has become a significant challenging issue in the world. Various methods have been reported in the literature to treat these effluents with adsorption and photocatalysis emerging as popular methods due to their low cost, simplicity and effectiveness in reducing the quantity of pollutants before they enter water bodies. This review summarizes key findings of the recent few years on the application of metal oxide nanoparticles in wastewater treatment. Adsorption alone is effective for removing pollutants even in very trace amounts, but it does not break down into eco-friendly products. Photocatalysis, on the other side, needs the adsorption of contaminants onto the catalyst surface to initiate degradation. Thus, this review provides a discussion on the mechanism of adsorption, as well as photocatalysis.

Abstract

Wasted sweet potato peel waste is a classic problem in Indonesia, therefore the use of sweet potato peel as biomass for bio-battery production can be used as a solution to this problem. This study aimed to determine the benefits of sweet potato peels and orange solution as biomass for bio-battery production. The main novelties in this study are (1) Used sweet potato peels as bio-battery Material that have never been used in previous studies. (2) Used sweet potato peel as fixed variable and lime juice as independent variable, and (3) Tested the sweet potato peel and lime juice pasta into the clock. This method is done by smoothing the skin of the sweet potato with the addition of 40 mL of lime solution to form a paste. The lime solution used in this study was 0; 5; 10; 15%. Then measure the voltage of the bio-battery and test the wall clock with the bio-battery. The experimental results showed that the sweet potato peel paste with a lime solution produced the same voltage as an ordinary battery at a concentration of 10% with a value of 1.47 V. The bio-battery with the highest concentration variation is not necessarily the best, that's because the pH value affects the current and voltage. The conclusion of this research is that sweet potato peel and lime solution can be used as electrolytes in bio-battery production with optimal variation of 5 and 10%. This study demonstrates the utilization of sweet potato peel waste as an alternative biomass for bio-battery production.

Abstract

Fatty acids are vital components of biological membranes and key metabolic fuels in living organisms. Their composition influences the nutritional and functional properties of food. This study aimed to compare the fatty acid profiles of groundnut and cashew nut to determine their nutritional value. Using the AOAC in 2000 method, samples of both nuts were analysed through gas chromatography. Groundnut oil was found to contain higher concentrations of oleic acid (46.99%) and linoleic acid (9.91%), while cashew nut oil had higher levels of palmitic acid (22.88%) and lauric acid (18.98%). The total fatty acid concentration in groundnut exceeded that of cashew, indicating that groundnut is richer in fatty acids overall. This comparison highlights the superior fatty acid content of groundnut, which could inform nutritional recommendations and food formulation strategies. The findings contribute to food science literature by emphasizing the value of groundnut as a high-fatty-acid food source.

Abstract

This project focuses on the processing and interpretation of magnetic and IP-resistivity data, which is to understand the subsurface geological structures and identify potential mineral resources. The data acquisition used appropriate geophysical instruments, including data filtering, imaging, inversion, and modeling techniques. The results obtained from the data analysis provide valuable insights into the subsurface geology. The magnetic data interpretation helps in delineating magnetic anomalies associated with different rock types, structural features, and potential mineralization. The IP-resistivity data interpretation aids in understanding the distribution of electrical properties within the subsurface, which can be indicative of lithological variations, fluid content, and potential mineral deposits. Through the integrated interpretation and correlation of magnetic and IP-resistivity data, important subsurface features and their relationships are identified. This information contributes to a better understanding of the geological framework and potential mineral resources in the study area. The findings of this research have implications for mineral exploration and development, as they provide a basis for further investigation and targeted exploration activities in the region. This project contributes to the knowledge base in geophysics and geology. The results enhance our understanding of the subsurface geology and mineral potential, supporting sustainable development and resource management in the area.

Abstract

Corrosion remains a critical challenge across various industries, necessitating the development of eco-friendly alternatives to conventional anti-corrosion methods. This study evaluates the performance of biocoating composed of rice husk silica and damar resin in inhibiting corrosion of mild steel in a 1M NaOH solution. The effects of drying temperature (27, 50, and 100°C) and duration (10, 30, 60 minutes) on corrosion resistance were systematically investigated. Optimal conditions were identified at 100°C for 10 minutes, achieving a corrosion rate of 0.041 mm/year and an inhibitor efficiency of 80%. Prolonged drying or higher temperatures resulted in reduced performance due to structural degradation. Comparative analysis revealed that these biocoating outperform untreated mild steel and are comparable to other natural inhibitors in terms of efficiency. The synergistic combination of rice husk silica and damar resin provides both physical and chemical protection, addressing the limitations of traditional methods. However, challenges in scaling up biocoating production, such as variability in material properties and integration into industrial processes, highlight the need for standardized protocols and further optimization. This study advances the understanding of biocoating mechanisms in alkaline environments, offering insights into their durability and effectiveness. The findings underscore the potential of rice husk silica and damar resin biocoating as sustainable, high-performance solutions for industrial corrosion protection.
