Abstract

The automatic analysis of images for the early detection of cervical cancer relies on the segmentation of cervical precancerous lesions. This paper investigates the incorporation of various CNN-based backbones into a U-Net model for improved segmentation accuracy. A set of twelve backbones was tested, including VGG16, VGG19, ResNet50, ResNext50, EfficientNetB7, InceptionResNetv2, DenseNet201, InceptionV3, MobileNet V2, SE-ResNet50, SE-ResNext50, and SE-Net154. Evaluation metrics were computed using Intersection over Union, pixel accuracy, and Dice coefficient. The findings demonstrate that U-Net with EfficientNetB7 backbone outperforms all other models with an IoU of 73.13%, pixel accuracy of 89.92%, and a Dice coefficient of 77.64%. These results were visually confirmed; segmentation outputs were examined, showing accurate delineation of lesion borders. The dominating performance of EfficientNetB7 was observed to be due to high feature extraction efficiency coupled with powerful spatial information representation. The study is, however, limited by a lack of clinical validation and expert evaluation from trained medical personnel. The results demonstrate the effectiveness of combining the U-Net architecture with advanced CNN backbones towards designing automated systems to analyze medical images.

Abstract

Arrhythmia is a disturbance in the electrical activity of the heart that can affect the rhythm and duration of the heartbeat. Early detection of arrhythmia is crucial to prevent more serious complications. Electrocardiogram (ECG) is an effective non-invasive diagnostic tool in detecting arrhythmia, but manual detection by experts takes time. To overcome this limitation, this research develops an arrhythmia classification system by utilizing deep learning. This study involves a series of stages, starting from pre-processing, feature extraction, and arrhythmia classification models using convolutional neural networks (CNN) and long short-term memory (LSTM). The results showed that feature extraction successfully improved model efficiency and accuracy. Evaluation of model performance using accuracy, recall, precision, specificity, and F1-score metrics showed that the LSTM model achieved 95% accuracy, 96% recall, 96% precision, 99% specificity, and 96% F1-score, outperforming the CNN model which achieved 91% accuracy, 90% recall, 89% precision, 98% specificity, and 89% F1-score. Thus, these results indicate that the LSTM model is superior in arrhythmia classification.

Abstract

Acute myocardial infarction (AMI) carries a significant risk, emphasizing the critical need for precise diagnosis and prompt treatment of the responsible lesion. Consequently, we devised a neural network algorithm in this investigation to identify myocardial infarction (MI) from electrocardiograms (ECGs) autonomously. An ECG is a standard diagnostic tool for identifying acute MI due to its affordability, safety, and rapid reporting. Manual analysis of ECG results by cardiologists is both time-consuming and prone to errors. This paper proposes a deep learning algorithm that can capture and automatically classify multiple features of an ECG signal. We propose a hybrid convolutional neural network (CNN) and long short-term memory (LSTM) for automatically diagnosing MI. To generate the hybrid CNN-LSTM model, we proposed 39 models with hyperparameter tuning. As a result, the best model is model 35, with 86.86% accuracy, 75.28% sensitivity and specificity, and 83.56% precision. The algorithm based on a hybrid CNN-LSTM demonstrates notable efficacy in autonomously diagnosing AMI and determining the location of MI from ECGs.

Abstract

This article analyzes the implementation of legal protection for child victims of prostitution in Lampung Province and its contribution to the development of child protection law in Indonesia. The research aims to evaluate the alignment between child protection practices and the provisions of Islamic law and positive law, and to identify regulatory needs that support comprehensive protection for child victims of sexual violence. The theory used is the theory of mashlahah mursalah, which emphasizes general welfare. This study employs field research with a qualitative approach and inductive reasoning. Data were collected through interviews and documentation from the Women and Children's Protection Agency of Lampung Province. The findings indicate that the implementation of legal protection for child victims of sexual violence falls short of the expectations set by the constitution and legislation. There is a need for more stringent policies to ensure that victims receive legal protection and free access to necessary facilities. The conclusion of this research is that efforts to protect child victims of sexual violence require regulatory improvements to align with the mandate of the 1945 Constitution. The contribution of this study lies in the development of policy recommendations that can enhance legal protection for children in Indonesia and provide insights into the importance of synergy between Islamic law and positive law in protecting children's rights.

Abstract

Ultrasonography, a medical imaging technique, is often affected by various types of noise and low brightness, which can result in low image quality. These drawbacks can significantly impede accurate interpretation and hinder effective medical diagnoses. Therefore, improving image quality is an essential aspect of the field of ultrasound systems. This study aims to enhance the quality of ultrasound images using deep learning (DL). The experiment is conducted using a custom dataset consisting of 2,175 infant heart ultrasound images collected from Indonesian hospitals, and the model is subsequently generalized using other datasets. We propose enhanced deep residual network combined convolutional neural networks (EDR-CNNs) to improve the image quality. After the enhancement process, our model achieved peak signal-to-noise ratio (PSNR) and structural similarity index metrics (SSIM) scores of 38.35 and 0.92 respectively, outperforming other methods. The benchmarking with other ultrasound medical images indicates that our proposed model produces good performance, as evidenced by higher PSNR, lower SSIM, a decrease in mean square error (MSE), and a lower contrast improvement index (CII). In conclusion, this study encapsulates the forthcoming trends in advancing low-illumination image enhancement, along with exploring the prevailing challenges and potential directions for further research.

Abstract

This research is aimed at discovering a stable financial scheming formula or model that would be compatible with the natural characteristics of a paddy farming cycle in Tuban. The qualitative research employs the use of an active participatory community through the means of a focus group discussion, an in-depth interview and face to face interviews with respective stakeholders and key informants. The Salam contract, which is highly beneficial is a prospective f inancial scheme that terminates the long business chain found in most businesses in Indonesia. The Corporate Social Responsibility which is managed through the Syariah approach (I-CSR) from a company, can become the solution to bridge the gap found in the implementation of funds for a Salam contract. The Salam contract applicability is dependent on the Islamic farmer cooperatives (BMT), a unit of joint venture organization serving as the key players in the execution of the function of a paddy warehouse-trading agent and direct financing to farmers. Strong support also comes from the zakat, infāq, and shodaqoh institution (LAZ) whose role is educating and encouraging the paddy farmers’ skills and competency, especially to enable them access end-user markets using the aid of information technology Abstrak:Penelitian ini bertujuan untuk menemukan formula skema pembiayaan pertanian yang stabil sesuai karakteristik dengan alamah pertanian padi di Kabupaten Tuban. Metode penelitian kualitatif digunakan dalam menyelesaikan penelitian ini dengan partisipasi komunitas aktif melalui media diskusi kelompok, wawancara mendalam tatap muka dan observasi kepada informan kunci dan pihak yang terlibat secara langsung dalam tata niaga pertanian padi di Kabupaten Tuban. Kontrak salam adalah skema pembiayaan yang sangat menguntungkan bagi petani dan pada penerapannya mampu mengambil pembiayaan peran distributor dalam tata niaga pertanian padi. Islamic Corporate Social Responsibility (I-CSR) yang dikelola berdasarkan ekonomi syariah dari perusahaan yang beroperasi di prinsip wilayah Tuban bisa menjadi solusi dana yang dikembangkan untuk pembiayaan pertanian yang dihindari oleh perbankan karena siklus bisnis yang berbeda. Keberlangsungan kontrak salam pertanian untuk komoditas padi akan bergantung pada koperasi petani yang terdiri dari koperasi simpan pinjam Syariah (BMT), gudang padi, penggilingan padi dan unit perdagangan yang kesemuanya disebut sebagai KUB (Kelompok Usaha Bersama). Dukungan yang kuat juga berasal dari Lembaga zakat, infāq dan shodaqoh, yang memiliki peran untuk melakukan pelatihan keahlian petani dan membantu memenuhi kebutuhan dasar petani yang menjadi anggota dalam KUB.

Abstract

Like many other cities, the industrial region of Gresik encounters problematic issues inherent in the burgeoning quantities of waste in landfill sites despite frequent policy implementations and other efforts from the local government. This study aims to examine and interlink between the possibility of the waqf concept and the growing number of waste issues in the Gresik industrial region. By harnessing ethnographical principles such as employing direct and consistent observations and reviewing numerous relevant literature surveys and archival documents, the study attempts to propose an executable design and model that will serve as a framework for stakeholders to address the weaknesses of current less favourable waste treatment programs. A comprehensive and rigorous consideration concludes that the viability of waqf can be a workable prospect and nucleus for an alternative solution and a complementary voluntary enhancement of effective regional policies and programs. An actionable and contributable waqf aspiration can start from the reformulation and rejuvenation of a rural waste bank which is designed to manage an effective balance between profitable and eco-friendly objectives. Professionalism and competence are significant factors in successfully enhancing the functionality of such an institution. Apart from the micro perspective, the bigger picture of a nexus of waqf and waste, including the current intermittent commitment from top policy makers transferred into timely execution, futuristic applicable technology, charitable giving and donation, and sensible collaborative cooperation, constitutes the conceivable determinants for the accomplishment of an efficacious program.

Abstract

The decline in textile exports and the increasing complexity of supply chains have intensified operational challenges for small-scale textile export agents. This study aims to identify key operational barriers affecting work effectiveness and to formulate improvement strategies based on practitioners' experiences. A qualitative single-case study was conducted at a privately owned textile export company in Indonesia (Company X). Data were collected through in-depth interviews with two key informants and triangulated with managerial perspectives, limited observation, and document analysis. The data were analyzed using thematic analysis following Braun and Clarke's framework. The findings reveal five interrelated operational barriers: quality inconsistencies and repeated sample revisions; production and delivery delays; weak contractual governance; fragile coordination and communication systems; and psychological pressure arising from export agents' intermediary role. These barriers reduce work effectiveness in terms of quality, speed, dependability, flexibility, and cost. The study proposes three improvement strategies: strengthening contractual governance and sanctions, adopting simple digital systems for coordination and monitoring, and enhancing supplier capacity and quality control, supported by leadership involvement. This study contributes to the governance and coordination literature by highlighting the operational realities of small-scale export agents in developing countries and emphasizing the importance of transitioning from informal, manual practices to structured, digitalized operations.
