Mangrove ecosystem in Pekalongan city provides significant ecological functions, biodiversity hot spots, economic and social benefits, ecosystem services, coastal protection, and sources of livelihood for local people in Central Java. Currently, this mangrove ecosystem is undergoing significant degradation, primarily due to anthropogenic activities such as waste from the batik industry, textile production, and residential areas., Mangroves, which are a fence between land and sea, are very likely to be exposed to microplastic waste. Waters and sediment samples were analyzed to find the microplastics at mangrove area. The analyzed of shape, size and colors using Microscope Motic SMZ-161 equipped with camera and the functional group of the polymers were analyzed using ATR-FTIR. From this research the microplastics abundance were 109 particles/l from total of all research stations in the water column and 153 particles/kg from total of all research stations in the sediment. The functional group polymer identified the polyamide, polystyrene, rayon, polyethylene terephthalate, polyethylene, and polyester at this research area. The anthropogenic activities in this area will increase waste in the form of microplastics and other chemicals, which will end up in marine waters and can have an impact on the mangrove growth and health. © 2025, The Authors.

The effects of hematite and brucite additions on fresh- and hardened-state properties of metakaolin-based geopolymer were investigated. Metakaolin-based geopolymer was produced with three Si/Al molar ratios and supplemented with hematite or brucite using three Fe/Al and Mg/Al molar ratios. Rheology, setting time, permeable porosity, compressive strength, and resistance to sulfuric acid of metakaolin-based geopolymer were measured. Experimental results show that, at Si/Al = 1.75 and 2.0, the hematite addition reduced the setting time whereas the brucite addition prolonged setting times, indicating an accelerated and delayed alkali-activation process of metakaolin-based geopolymers, respectively. At Si/Al = 1.5, both additions accelerated the setting time but increased the permeable porosity. Both additions reduced the bulk mechanical properties but improved sulfuric acid resistance. Pastes with brucite exhibited better sulfuric acid resistance than the counterpart with hematite. The paste immediately surrounding the agglomerates of hematite and brucite particles exhibited lower and higher micromechanical properties, respectively. © 2024, The Authors. All rights reserved.

The past COVID-19 pandemic has led to a surge in the use of disposable masks, posing a significant environmental challenge due to the swift accumulation of waste. This study explores the potential of pyrolysis to transform this waste into valuable pyrolysis oil with characteristics akin to gasoline, addressing both waste management and energy derivation concerns. Pyrolysis, a thermal decomposition process, was applied to mask materials, producing an oil with a high calorific value of 45.93 MJ/kg. The chemical makeup of this pyrolytic oil was meticulously characterized using Pyrolysis-Gas Chromatography-Mass Spectrometry (PY-GC/MS) and Fourier-transform Infrared Spectroscopy (FTIR), confirming the presence of hydrocarbons similar to those found in gasoline. Achieving an efficiency of 41.865 %, the pyrolytic approach demonstrated a promising potential for not only managing mask waste but also creating an alternative energy carrier. However, the study advises that before considering this pyrolytic oil for engine use, a thorough evaluation of its combustion quality, engine compatibility, and environmental impact is essential. This investigation advances the discussion on sustainable waste management, offering insights into the generation of alternative fuels from daily waste streams, while also highlighting the necessity for comprehensive analyses to ensure the practicality and efficiency of such novel energy solutions. © 2023 The Author(s)

Recently, the overuse and misuse of antibiotics are key factors leading to many negative problems to human and environment. Therefore, the removal for the antibiotics is very necessary, and photocatalysis is a highly efficient and environmentally friendly treatment method. Graphite carbon nitride (\mathrm{g}-\mathrm{C}_{3}\mathrm{N}_{4}) is an organic semiconductor, researched to create a 'new-generation' photocatalytic material system by hybridization with semiconductors such as TiO2 and ZnO, which offers potential energy in the decomposition of organic compounds using the energy of visible light. In this study, ZnO/g-C3N4 materials were synthesized and characterized by advanced techniques, then apply for ciprofloxacin antibiotic (CIP) treatment. The CIP degradation efficiency of the material reached 84.36% and after three times the material was regenerated, ZnO/g-C3N4 composite still showed excellent degradation ability. Therefore, ZnO/g-C3N4 materials can be applied in environmental remediation and many other fields. © 2022 IEEE.

This work in progress research-to-practice paper describes research-based approaches for the development of course modules for teaching virtue-based engineering ethics in undergraduate engineering courses. Engineers play a pivotal role in society. Therefore, it is critical to train engineering students to be ethical engineers. Most of the engineering ethics training offered currently focuses on technical ethics, not focusing on the development of the whole person. Furthermore, students often show a lack of interest in current engineering ethics training and case studies often lack context. Prior research has shown that virtue-based character education offers a viable approach for more holistic engineering ethics training. A character approach to engineering ethics offers personal motivation and actionable dimensions to ethical reasoning. However, within the field of engineering ethics, currently only limited studies have been done on virtue-based character education in undergraduate engineering courses. In this study, we develop stories from traditional culture of different countries into teaching modules to help engineering students identify virtues present in the stories and make connections to engineering ethics. The teaching modules include short virtue-of-the-week stories at the beginning of class and team-based class activities for connecting virtues to ethics. We integrate the teaching of ethics with students' coursework to help them realize the importance of virtues and ethics when solving problems and working as a team in class. Preliminary findings from the pilot study in a capstone design course at a large public university in the US suggest the teaching modules help students be more aware of the connections between virtues and engineering ethics and students are engaged and interested in our approach. Our study will advance knowledge in the field of engineering ethics by investigating how stories from traditional culture help students understand engineer

Fresh water is needed in industrial activities. For these needs sea water is usually used as raw material if the plant is near the sea and far from the river. SWD (sea water desalination) is used to process sea water to fresh water, that is by reducing levels of salinity or reducing levels of total dissolved solid (TDS). There are two technologies in SWD, namely thermal distillation and reverse osmosis (RO) membrane technology. Residual SWD process or also called blowdown water has high salinity levels can be converted into electrical energy through SGP (salinity gradient power). There are two technologies to capture energy from salinity differences, namely PRO (Pressure Retarded Osmosis) and RED (Reverse Electrodialysis). PRO and RED are renewable energy technology, there are no emision, no moving part, abundant availability in nature and can be recycled. In this article, an analysis for SWD of oil refinery is carried out. From the analysis results it is known that the plant uses thermal distillation technology, requires power as 64.25 MW and 3,403 m3/h seawater to produce 242 m3/h freshwater. With SGP, the potential recovery of power gained is 0.786 MW. This recovery potential is still too small when compared to energy requirements of SWD with thermal distillation technology, but if it use RO technology that only requires 3.6-5.7 kWh/m3 or 0.87 - 1.40 MW to produce 242 m3/h, a significant impack to saving energy will be obtained. © Published under licence by IOP Publishing Ltd.

Polyamide (PA) thin-film composite (TFC) membranes, fabricated by interfacial polymerization (IP) process, have been widely used for the desalination process due to high water permeability with high water/salt selectivity. A number of advanced PA TFC membranes have been developed as more efficient alternatives to further improve separation performance and address the surface contamination problem of commercial membranes. Here, we utilized amphiphilic functionalized cellulose nanocrystal (f-CNC) having antibacterial property as a nanofiller material for the preparation of an advanced PA membrane system, featuring improved water permeability with high salt rejection ability. This strategy is inexpensive, scalable, environmentally friendly, and practically relevant, given that typical IP process with a renewable nanofiller was employed. The amphiphilic f-CNC manipulates interfacial diffusion of monomers upon IP process, thereby decreasing the effective PA layer thickness by 30% (from ~377 nm to ~268 nm) and increasing water permeability by 44% (from 1.26 Lm-2h-1bar-1 to 1.82 Lm-2h-1bar-1). In addition, the PA membrane with f-CNC showed improved antibacterial (~90%) and antifouling properties (~84%, FRR) due to the specific nature of f-CNC. This study provides insights for the development of thin, effective, and antibacterial, yet more green and scalable PA membrane alternatives to the conventional desalination membranes. © 2023, The Authors.

A novel double-coating technique was employed to encapsulate levofloxacin (LVF), a potent antibacterial drug, using the particles from gas-saturated solutions (PGSS) process to achieve extended release. The primary coating utilized glyceryl tristearate (GT), a lipid with a high melting point (72 °C), followed by a secondary coating with trimyristin (TM), a lipid with a lower melting point (52 °C). For comparison, a single-coating approach was also explored, using the biocompatible polymer poly-(ε-caprolactone) (PCL). The resulting particles were characterized for their shape, size, and LVF encapsulation efficiency, with confirmation of LVF entrapment provided by Fourier transform infrared (FTIR) spectroscopy, and X‐ray powder diffraction (XRD) analysis. The particles, with an average diameter of 95.3 ± 16.5 μm, exhibited an encapsulation efficiency of up to 92.1 ± 2.5%. Furthermore, in vitro release studies revealed that the double-coated microcapsules effectively suppressed the initial burst release and provided controlled, extended release of LVF (t30D = 36.3%), demonstrating the efficiency of this encapsulation method for prolonged drug delivery.

Fermented foods, such as kombucha, have gained popularity due to their rich content of beneficial bioactive compounds. Papaya leaves, known for their abundance of bioactive substances such as alkaloids, flavonoids, and phenolic compounds, have garnered attention for their potential to improve immune function by neutralising free radicals. This study investigates the suitability of papaya leaves and petioles as substrates for kombucha fermentation. Our findings indicate that papaya leaves and petioles were suitable substrates for kombucha fermentation, indicated by the SCOBY mass accumulation during fermentation. The gradual decrease in brix and pH values over a 14 days fermentation period corresponds to sugar metabolism and the accumulation of acetic acid. Additionally, fermentation increases total polyphenol (PPK: 250.07 ± 3.00 mg/L, PLK: 330.87 ± 15.56 mg/L) and total flavonoid content (PPK: 26.67 ± 6.31 mg/L, PLK: 34.44 ± 5.55 mg/L). Moreover, papaya-derived kombucha demonstrates enhanced antibacterial properties and inhibits ⍺-amylase linked to diabetes. Sensory evaluations confirm that papaya kombucha achieves a well-balanced and appealing sensory profile, catering to diverse palates. In summary, papaya leaves and petiole exhibit promise as substrates for kombucha production, offering elevated nutritional value and potential health advantages. © 2024 Institute of Food, science and Technology (IFSTTF).
