Abstract

This study aims to determine the optimal pH and stirring speed for the identification and removal of polyethylene terephthalate (PET) microplastics using chitosan extracted from crab shell waste (Scylla serrata) through the coagulation method. The chitosan extraction process involved demineralization, deproteinization, and deacetylation stages. Subsequently, the extracted chitosan was applied as a coagulant in a solution containing PET microplastics under various pH levels and stirring speeds. The results indicate that chitosan derived from crab shell waste is effective in reducing microplastic concentrations, achieving a removal efficiency of 97.30% under optimal conditions of pH 6 and a stirring speed of 250 rpm. These findings highlight the significant potential of utilizing marine waste as an eco-friendly natural biopolymer in microplastic wastewater treatment. This research contributes to the advancement of sustainable biopolymer-based waste treatment technologies and supports efforts to mitigate microplastic pollution in aquatic environments.

Abstract

Well water is a primary water source for communities and is vulnerable to contamination by heavy metals, particularly iron (Fe), which, at high concentrations, can cause organoleptic issues such as unpleasant odor, taste, and color, as well as pose health risks. According to Indonesian Ministry of Health Regulation No. 32 of 2017, the maximum allowable Fe content in water is 1 mg/L. This study aims to determine the concentration of Fe in well water samples from Padang City and evaluate the analytical data quality using Atomic Absorption Spectrometry (AAS). Water samples were collected and preserved with HNO₃ to maintain pH < 2, then analyzed using AAS at a wavelength of 248.3 nm. Method performance evaluation showed reliable analytical quality, with a calibration curve coefficient of determination (R²) of 0.9958, indicating excellent linearity. Accuracy validation through spike tests yielded recovery values within the acceptable range (85%–115%). However, the Relative Percent Difference (RPD) of duplicate samples indicated relatively high variability in precision (14.667%–26.415%), suggesting a need for optimization in the sample preparation stage. Despite this, precision in spike quality control showed excellent results, with an RPD of 0.221%. Quantitative analysis showed that all well water samples had Fe concentrations below the instrument detection limit, indicating compliance with water quality standards and general safety for sanitation and hygiene purposes.

Abstract

Gelatin is a collagen-derived product widely utilized in the food, pharmaceutical, and cosmetic industries, with moisture content being a critical quality parameter. This study aims to evaluate the effect of extraction methods on the moisture content of gelatin derived from chicken skin, using two different approaches: conventional waterbath and ultrasound-assisted extraction (sonication). The extraction process began with acid hydrolysis using citric acid, followed by waterbath treatment at 65 °C for 10, 20, and 30 minutes, and sonication at a frequency of 47 kHz for 10–50 minutes. Samples with the highest yield from each method (10-minute waterbath and 50-minute sonication) were analyzed for moisture content. The results showed that gelatin obtained via sonication had a moisture content of 9.51 ± 0.70%, while that obtained via waterbath was 10.21 ± 2.15%. A paired t-test yielded a p-value of 0.641, indicating that the difference in moisture content between the two methods was not statistically significant. Both values remain within the acceptable limit set by the Indonesian National Standard (SNI 01-3735-1995), which stipulates a maximum moisture content of 16%. Thus, both conventional and sonication methods are capable of producing high-quality gelatin in terms of moisture content, with slightly higher drying efficiency observed in the sonication method.

Abstract

Unhealthy lifestyles and environmental conditions have become key contributors to the increased production of free radicals in the body, which are linked to the development of various degenerative diseases. To counteract these effects, the body requires antioxidant compounds capable of neutralizing free radicals. Brassica oleracea (purple cabbage) is a vegetable known to contain bioactive compounds, particularly flavonoids, with potential as natural antioxidants. This study aims to determine the antioxidant activity of concentrated purple cabbage extract. The DPPH (2,2-diphenyl-1-picrylhydrazyl) method was employed, with extraction carried out through maceration using methanol as the solvent. Antioxidant activity was tested at various concentrations to determine the IC₅₀ value. The results showed that purple cabbage extract exhibited moderate antioxidant activity, with an IC₅₀ value of 144.170 mg/L. These findings indicate that purple cabbage holds promise as a natural antioxidant source, with potential applications in functional food and pharmaceutical development.

Abstract

This study examines the enhancement of the C-212-200 aircraft’s navigation system capability in supporting Weather Modification Operations (OMC) during the G20 Summit held in Bali in 2022, with a focus on the implementation of the Traffic Collision Avoidance System (TCAS) and Transponder Mode S as part of the system's modernization. The objective of the research is to analyze the effectiveness of integrating these two systems in improving flight safety, situational awareness, and operational efficiency. A descriptive qualitative approach with a case study design was employed, involving technical interviews, field observations, and document analysis within an operational unit of the Indonesian Air Force. The findings indicate that TCAS significantly enhances pilot situational awareness by providing real-time Traffic Advisory (TA) and Resolution Advisory (RA), enabling prompt and accurate conflict avoidance maneuvers. Meanwhile, Transponder Mode S strengthens two-way communication between the aircraft and Air Traffic Control (ATC) through selective interrogation, allowing precise transmission of aircraft position, identification, and altitude data. The integration of both systems has been shown to reduce pilot workload, minimize mid-air collision risk, and improve decision-making effectiveness, especially in high-traffic airspace such as during the G20 Summit. The study also highlights non-technical challenges, particularly the limited readiness of human resources—including avionics technicians and pilots—who require further training in operating and maintaining integrated digital navigation systems. Overall, the modernization of the C-212-200 navigation system through TCAS and Mode S proves effective in supporting non-combat flight operations more safely and efficiently, and represents a strategic step toward civil–military interoperability and digital transformation within the national air defense system.

Abstract

This study is motivated by the limited research on the use of natural biocoagulants for microplastic removal, despite the significant environmental and human health impacts of this phenomenon. The aim of this research is to analyze the influence of pH variation, chitosan dosage, and settling time on the coagulation effectiveness of polystyrene (PS) microplastics, and to determine the process's optimum conditions. A quantitative method was employed, using PS microplastic solution samples (30 mg/L) treated under varying pH levels (4–10), chitosan doses (10–50 mg/L), and settling times (10–50 minutes). Data were collected through laboratory experiments and analyzed using Fourier Transform Infrared (FTIR) spectroscopy and stereo microscopy. The results indicate that optimum conditions were achieved at pH 6, with a chitosan dose of 30 mg/L and a settling time of 30 minutes, resulting in microplastic removal efficiency exceeding 90%. These findings support the theory of electrostatic interactions between the amine groups in chitosan and the negatively charged surface of microplastics. The main conclusion is that crab shell-derived chitosan is effective as an environmentally friendly biocoagulant for reducing microplastic content in wastewater. The study contributes to the growing literature on biocoagulation and offers practical recommendations for wastewater treatment managers to adopt sustainable natural coagulants. Moreover, it opens avenues for future research on chitosan-based composites for treating various types of microplastics.

Abstract

The use of medicinal plants in Indonesia is still largely based on traditional knowledge passed down through generations, often lacking sufficient scientific validation. Momordica charantia L., a plant from the Cucurbitaceae family, is widely recognized in traditional medicine for its flavonoid content found in the leaves, which exhibits antioxidant, antidiabetic, antirheumatic, and antimicrobial properties. This study aims to determine the effect of sonication on the total flavonoid content of pare (bitter melon) leaves. Extraction was carried out using a sonicator for 60 minutes at 40 °C, with a power of 50 W and a frequency of 40 kHz. The filtrate obtained from the filtration process was then evaporated using a rotary evaporator with 70% ethanol as the solvent. The total flavonoid content was determined using a UV-Vis spectrophotometer at a maximum wavelength of 431 nm. The results showed that the sonication method produced a total flavonoid content of 159.42 mg QE/g, which is considered high. These findings indicate that sonication is a fast, efficient, and environmentally friendly extraction method for obtaining flavonoid compounds from Momordica charantia leaves. This study contributes scientifically to the development of modern green technology-based extraction methods for the utilization of local medicinal plants.

Abstract

This study examines the effectiveness of implementing the new Maintenance Work System (Sistem Tata Kerja or STK), enforced since 1 November 2024, in an oil and gas company, with a specific focus on the alignment between equipment criticality assessment outcomes and the revised STK requirements. The core issue lies in the potential shift in asset maintenance priorities and strategies due to misclassification of critical equipment, which may compromise operational reliability. The objective of this research is to revalidate the implementation of Equipment Criticality Assessment (ECA), Failure Mode Effect and Criticality Analysis (FMECA), and Reliability Centered Maintenance (RCM) to ensure they are applied more effectively and efficiently in accordance with international standards—IEC 60300-3-11, IEC 60812, and ISO 14224. The methodology includes document analysis of relevant standards, literature review, and criticality assessment of 182 equipment units using the Reliability Block Diagram (RBD) approach and SAP-based classification systems. The results show that turbomachinery, particularly Gas Turbine Compressors (GTC), remain classified as Production Critical Equipment (PCE), while the glycol system, auxiliary compressors, and gas metering units have been reclassified as secondary or supporting assets. The study recommends strengthening the technical competencies of the maintenance team, applying logic decision tree methodologies in the analytical process, and integrating evaluation outcomes into work scheduling policies and spare parts management. These findings offer practical contributions to the optimization of reliability-based maintenance systems and support more precise technical decision-making in the governance of strategic assets within the oil and gas sector.

Abstract

Numerous studies have demonstrated the effectiveness of cooperative learning models in enhancing academic achievement; however, research specifically addressing the application of the Cooperative Team Quiz (CTQ) model in high school history instruction remains relatively limited. This study aims to implement and evaluate the effectiveness of the CTQ model in improving student learning outcomes on the topic of the Proclamation of Independence. A quantitative approach was employed using a two-cycle Classroom Action Research (CAR) design. The study involved 46 eleventh-grade students (Class XI-5) from SMAN 8 Denpasar, selected through total sampling. Data were collected through learning outcome tests, student activity observations, and documentation, and analyzed using descriptive quantitative methods. The findings indicate a significant improvement in learning outcomes, with the average score increasing from 73.09 in the pre-cycle to 77.63 in Cycle I and 80.63 in Cycle II. The percentage of students achieving mastery rose from 43.48% in the pre-cycle to 80.43% in Cycle II. These results suggest that the implementation of the CTQ model effectively enhances students' active participation, strengthens group collaboration, and fosters motivation and engagement in history learning. The study concludes that the CTQ model offers a viable, innovative instructional strategy to improve both the process and outcomes of history education. The findings imply that teachers are encouraged to adopt this model as a pedagogical approach aligned with the demands of 21st-century learning. Further research is recommended to examine the model’s effectiveness across different subjects and educational levels to broaden the generalizability of the results.
