Abstract

Superabsorbent polymer (SAP) is a polymer that has one function as an absorbent material in baby diapers, whose quality is determined by the number of swelling capacity (SC). Many previous studies regarding the effect of synthesis parameters on the number of SC were limited to the laboratory scale, where the polymerization conditions, the number of variables, and SC data obtained were very limited, in contrast to the industrial scale. The radical polymerization stage, with its accompanying operating variables such as reaction temperature, monomer concentration, retention time, crosslinker concentration, the addition of nitrogen gas, and initiator concentration, affects the value of SC in industrial-scale production. This study aims to analyse the correlation between the reactor operating conditions and the number of SAP SC obtained. Correlation data analysis was done using Microsoft Excel with Data Analysis Toolpak and Python by utilizing production data with a total of 1,562 entries, where the correlation between each variable was calculated using Pearson’s correlation coefficient. The analysis determined that the variables that had the strongest correlation with the SC were retention time and reaction temperature, with correlation coefficient values of 0.31 and -0.26. The weakest correlation was obtained from the addition of nitrogen gas and an initiator with a value of -0.07 and -0.02. Positive values indicate a relationship that is directly proportional, while negative values indicate an inverse relationship. Based on the correlation analyses and trends, the ideal polymerization conditions have been identified.

Abstract

The role of renewable products is becoming important because the fossil resources in which most of our chemicals derived is vanishing. Agriculture as the renewable sources is needed to increase the production which is not only required to meet the food demands but also to replace chemicals that derived from fossil sources. Zeolite has a huge potential for agriculture intensification and conversion of agriculture products and by-products into chemicals. Indonesia has two kind deposit of natural zeolites, which are clinoptilolite and mordenite lies aligned volcanic mountain across Sumatra, Java, Nusa Tenggara and Sulawesi Islands. Zeolite has large surface area consisted of microporous and mesoporous structures. It could be utilized as an ion exchange agent, adsorbent and catalyst for applications in agriculture and agroindustry. Sustainable development of agricultural products could be also assisted by zeolite as slow-release fertilizer and controlling pests. Moreover, this review discusses about the integration of natural zeolite with chemical based wastes from livestock with nitrogen demand for cultivation is explained as a part of the idea of one-system-integrated farm and livestock. Storage and processing of agricultural products could be more efficient with the utilization of zeolite in drying, storage, processing and product preservation unit operations. Sucrose crystallization, catalytic reaction inulin to fructose, pinene isomerization and glycerol biodiesel by-product conversion is discussed in this review. As in general, zeolite porosity, topology, silicon to aluminium ratio, and acidity properties become an important factor on catalytic reactions to convert agricultural products into beneficial chemical substances

Abstract

Household liquid waste which contains ammonium is one of the major contributors to the wastewater effluent. The aim of investigation is to characterize and determine the adsorption capacity of natural zeolites from Cikalong for ammonium removal.  The effect of cations type, K+, Mg2+ and Ca2+, on ammonium desorptions was studied. Kinetic desorption study was also performed and fitted with various kinetic models. According to X-ray diffraction (XRD) pattern, the Cikalong natural zeolites were mordenite and clinoptilolite dominant type.  The morphology of the mordenite phase was appeared as needles shape. The ratio of Si to Al was 6.86 according to X-ray fluorescence (XRF). The surface area was 187 m2/g which was determined by Brunauer–Emmett–Teller (BET) model. Desorption using K+ solution showed the shortest time and the highest rate for ammonium desorption. The calculation using nonlinear method was carried out to optimize the desorption kinetic parameters. The pseudo 1st order desorption kinetics model showed the smallest error with sum of squared error (SSE) 0.00209.

Abstract

Methane as a potential green house gases contributor which gives 21 GWP has to be mitigated to diminish the global warming effect. High concentration methane can be easily converted into CO2 by mean oxidation. However lean methane can only be oxidized in catalytic reaction system as the catalyst lowers the reaction temperature up to 400 oC. Nevertheless, this is still high temperature to achieve by low concentration and low temperature feed. It still needs preheating the feed until its reaction condition reached which can be supplied outside or within the system called auto thermal. One of promising auto thermal reactor is reverse flow reactor which is the reactor that its feed flow periodically switches to make the heat trapped inside the reactor. In this work we have designed reverse flow reactor by one-dimensional model, pseudohomogeneous for mass and heterogeneous for energy to burn lean methane from a station compressor. The critical parameter of switching time on the system of periodical reversal is also presented

Abstract

Sustainable materials are essential in achieving the Sustainable Development Goals (SDGs), particularly in clean energy, water purification, waste reduction, and green infrastructure. This study investigates the role of material innovation in supporting the SDGs using a Systematic Literature Review (SLR) and bibliometric analysis (from Scopus database (2015–2025) using keywords “Sustainable Material,” “Green Material,” and “SDGs”). The findings showed a growing research trend, especially after the COVID-19 pandemic, with significant contributions from chemistry, engineering, and environmental sciences. Materials like nanomaterials, biomaterials, biodegradable polymers, and waste-derived products contribute to SDG 6, 7, 9, 12, and 13. Innovations such as green nanotechnology, bio-based materials, and circular material design show strong potential to address global sustainability challenges. These materials not only support emission reduction and waste valorization but also encourage green job creation and sustainable production. This study highlights interdisciplinary pathways to align material science with sustainable development.

Abstract

This study examines the integration of nanotechnology into chemical engineering education and its implications for future curriculum development. A bibliometric and technological review was conducted using publications from major scientific databases, with standardized datasets and mapped collaboration and keyword networks to identify pedagogical and curricular trends. The findings indicate a steady growth of interdisciplinary research linking nanoscale concepts with process engineering, accompanied by increasing adoption of virtual laboratories, computer simulations, and intelligent tutoring systems. Nevertheless, challenges remain, including uneven faculty preparedness, limited access to advanced instrumentation, and the lack of unified competency frameworks across institutions. These constraints are largely driven by macro-centric teaching traditions, resource limitations, and inconsistent curriculum standards. To address these gaps, the study proposes targeted updates to core and elective courses that emphasize nano-centric content, sustainability, and digital pedagogy. Overall, the paper presents a practical framework aligned with Safe-by-Design principles and the United Nations Sustainable Development Goals.
