Abstract

Turbofan engines have been the dominant type of engine in aircraft for the last forty years. Ensuring the quality of these engines is crucial for flight safety, particularly for long-distance flights. However, their performance degrades over time, impacting flight safety. To address this issue, it is essential to predict potential engine failures by estimating the Remaining Useful Life (RUL) of the engines Deep learning, especially Convolutional Neural Networks (CNNs), has demonstrated exceptional proficiency in handling intricate, non-linear data, leading to improved RUL predictionsdue to their ability to process complex and non-linear data. In this project, a 1-D CNN is used to predict RUL using the NASA C-MAPSS FD001 dataset, which consists of 3 settings and 21 sensors, though sensors with stagnant readings are excluded. The dataset is normalized using min-max and z-score methods, and then segmented into sequences for input into the 1-D CNN model. Various training scenarios were evaluated, with the best RMSE of 3.26 achieved using 10 epochs, a learning rate of 0.0001, and z-score normalization. The results indicate that feature selection can produce a lower RMSE compared to scenarios without feature selection.

Abstract

Although ZnO photocatalysts show potential for wastewater treatment, their low efficiency limits the commercialization. To address this problem, we investigated the effect of co-doping ZnO with selenium (4%, fixed) and sulfur (0.5, 1, and 1.5 wt%). The catalysts were synthesized using Matoa leaf extract and zinc nitrate hexahydrate while being subjected to 540 W microwave irradiation. UV-Vis analysis revealed absorption peaks at 340-398 nm with sulfur doping increasing the band gap. XRD confirmed the preservation of the hexagonal wurtzite structure, while FESEM images showed a morphological transformation from nanoflowers to petal flakes with increasing sulfur content. EDX analysis confirmed the presence of S, Se, Zn, and O, while FTIR analysis identified OH groups from the extract in the nanoparticles. BET surface area was found to progressively reduced from 24.58 to 16.86 m²/g with sulfur doping. The co-doped catalyst with 0.5 wt% sulfur (0.5S(4Se-ZnO)) demonstrated the highest degradation of 4-nitrophenol at 99.69%, indicating its applicability in industrial wastewater treatment. These findings indicate that the Se/S co-doped ZnO, prepared via a green synthesis route, holds a strong promise as an efficient and practical photocatalyst for addressing environmental pollution in a sustainable and economical manner.

Abstract

The synthesis of pyridazinone derivatives has gained increasing attention due to their diverse biological activities, particularly as anticancer agents. In this study, novel pyridazinone derivatives substituted with methoxy groups and phenyl hydrazine were synthesized through a multi-step reaction pathway, starting from methoxyacetophenone and glyoxylic acid, followed by cyclization and substitution reactions to yield the target compound 7-(2-methoxyphenyl)-2H-pyridazino[6,1-c][1,2,4]triazine-3(4H)-one. The synthesized compounds were characterized by melting point, TLC, HPLC, UV-Vis, FTIR, NMR, and MS analyses, confirming the expected structures. In silico evaluation was performed using molecular docking against estrogen receptor α (ERα) kinase domain (PDB ID: 1T46), a key protein in breast cancer progression. The docking results showed that the synthesized compounds exhibited strong binding affinities, with compound 8 displaying a binding free energy of –9.1971 kcal/mol and stable interactions with residues Cys673, Leu799, and Phe811. These values were superior compared to the natural ligand and comparable to the reference drug doxorubicin, indicating significant anticancer potential. The results suggest that structural modification of pyridazinone with methoxy and phenyl hydrazine substituents enhances its cytotoxic activity, making it a promising candidate for further development as an anticancer agent.

Abstract

This study investigates the learning needs of senior high school students in West Sumatra, Indonesia, regarding short story writing. Understanding these needs is essential to develop effective instructional strategies that enhance students’ writing skills. A qualitative research design employing a descriptive analysis method was used. Data were collected through an exploratory case study involving 295 students and 15 teachers from four senior high schools. Instruments included short story writing tests, student questionnaires, and interviews with both students and teachers. The collected data were analyzed using content analysis techniques. Findings indicate that students benefit from a problem-based flipped classroom model, where they study materials at home and complete tasks in class. They also require a problem-based learning approach that emphasizes autonomy, motivation, creativity, logical reasoning, and experiential learning. Preferred learning media are digital, engaging, and flexible—accessible from home and adaptable to individual pacing. In terms of assessment, students favor ongoing, collaborative evaluations that align with the learning process. They also value assessments that directly support the development of their writing skills through constructive feedback and skill-targeted assignments. The results suggest that integrating digital tools and active learning models can better support students’ engagement and progress in short story writing. Instructional designs should reflect students' preferences for autonomy, creativity, and continuous feedback.

Abstract

The habit of Islamic character values is one of the strategic efforts in shaping the behavior and attitudes of students, including in improving learning discipline. Islamic values such as honesty, responsibility, discipline, and obedience to rules are believed to be closely related to student learning behavior at school. This study aims to determine the relationship between the habit of Islamic character values and student learning discipline. This study used a quantitative approach with a correlational design. Data were collected through questionnaires on the instillation of Islamic character values and student learning discipline. Data analysis techniques used the Chi-Square test to determine the relationship between two categorical variables. The results showed that there was a significant relationship between the instillation of Islamic character values and student learning discipline (p < 0.05). These findings indicate that the better the habit of Islamic character values, the higher the level of student learning discipline. Therefore, the habit of Islamic character values needs to be continuously strengthened as an integral part of the educational process in schools.
