Abstract

These days, the application of image processing in computer vision is becoming more crucial. Some situations necessitate a solution based on computer vision and growing deep learning. One method continuously developed in deep learning is the Convolutional Neural Network, with MobileNet, EfficientNet, VGG16, and others being widely used architectures. Using the CNN architecture, the dataset consists primarily of images; the more datasets there are, the more image storage space will be required. Compression via the discrete cosine transform technique is a method to address this issue. We implement the DCT compression method in the present research to get around the system's limited storage space. Using DCT, we also compare compressed and uncompressed images. All users who had been trained with each test 5 times for a total of 150 tests were given the test. Based on testing findings, the size reduction rate for compressed and uncompressed images is measured at 25%. The case study presented is face recognition, and the training results indicate that the accuracy of compressed images using the DCT approach ranges from 91.33% to 100%. Still, the accuracy of uncompressed facial images ranges from 98.17% to 100%. In addition, the accuracy of the proposed CNN architecture has increased to 87.43%, while the accuracy of MobileNet has increased by 16.75%. The accuracy of EfficientNetB1 with noisy-student weights is measured at 74.91%, and the accuracy of EfficientNetB1 with imageNet weights can reach 100%. Facial biometric authentication using a deep learning algorithm and DCT-compressed images was successfully accomplished with an accuracy value of 95.33% and an error value of 4.67%.

Abstract

Industrial processes that discharge heavy metals into the environment are a growing environmental crisis because of the dangers they pose to aquatic life and human health. Nickel (Ni) is one of the most dangerous metals due to its extreme toxicity and its ability to bioaccumulate in food chains. Severe health complications may develop from chronic exposure to nickel. Chemical precipitation, ion exchange, and reverse osmosis are traditional methods used to remove Ni(II) ions from wastewater. Nonetheless, these approaches have drawbacks, such as elevated operational costs, excessive chemical consumption, and inefficiency in treating low-concentration wastewater. The effectiveness of solvothermally synthesised chitosan as an adsorbent for the removal of Ni(II) ions from aqueous solutions was examined in this work. Acidity, adsorbent concentration, and contact duration were all carefully measured and analyzed. Optimal adsorption occurred at pH 6, yielding a maximum removal effectiveness of 75% after 75 minutes of contact. An adsorption efficiency of 54.69% was achieved with the optimal adsorbent dose of 0.4 g. Kinetic analysis indicated that the adsorption process followed the Pseudo-Second-Order (PSO) model, with a correlation coefficient (R²) of 0.999, suggesting that chemisorption prevailed via interactions between Ni(II) ions and the –NH? and –OH functional groups on the chitosan surface. The solvothermal modification improved the adsorption capability of the chitosan by increasing its surface area, porosity, and number of active sites.

Abstract

This case study explores the development of independence in an elementary school-aged child with Autism Spectrum Disorder (ASD). Using qualitative methods—including direct observation, semi-structured interviews, and document analysis—the study identified key factors that facilitated independent behavior in both home and school settings. The child demonstrated increased autonomy in daily tasks such as toileting, dressing, and class participation, particularly when supported by structured interventions including visual schedules, task analysis, and token reinforcement systems. A significant finding was the role of consistent collaboration between parents and teachers, which enabled the child to generalize skills across environments. These results affirm the importance of individualized support strategies and inter-setting consistency in promoting independence among children with ASD. The study concludes by recommending sustained, context-sensitive interventions and further research across multiple participants and settings to inform evidence-based practices in special education.

Abstract

Hernia umbilikal merupakan kondisi penonjolan viskus intraabdominal melalui cincin umbilikalis akibat kelemahan dinding perut. Penyakit ini dapat terjadi pada anak maupun dewasa, dengan faktor risiko antara lain peningkatan tekanan intraabdominal (obesitas, kehamilan, asites) dan kelemahan jaringan ikat. Untuk menjelaskan gambaran klinis, faktor risiko, diagnosis, dan penatalaksanaan hernia umbilikalis.Penulisan dilakukan dengan metode tinjauan pustaka dari berbagai literatur terkait hernia umbilikalis, meliputi aspek anatomi, epidemiologi, etiologi, klinis, diagnosis, dan terapi. Hernia umbilikalis sering ditemukan pada bayi prematur karena belum sempurnanya penutupan cincin umbilikalis, sedangkan pada dewasa lebih sering dipicu oleh kondisi peningkatan tekanan intraabdominal. Diagnosis ditegakkan berdasarkan pemeriksaan fisik berupa benjolan di daerah umbilikus yang menonjol saat batuk atau mengejan. Komplikasi yang dapat timbul adalah inkarserasi dan strangulasi. Terapi utama pada kasus simptomatik maupun berisiko komplikasi adalah hernioplasti atau herniorafi. Hernia umbilikalis merupakan kelainan dinding perut yang cukup sering terjadi, dengan diagnosis klinis yang relatif mudah ditegakkan. Penatalaksanaan definitif berupa tindakan operatif perlu dipertimbangkan untuk mencegah komplikasi serius.
