Abstract

Periampullary carcinoma is a malignancy that appears around the vatteri ampulla. This malignancy can originate from the pancreas, duodenum, and distal choledochal duct. Duodenal cancer is a very rare case, only about 0.3% of the gastrointestinal malignancies. Reported cases are increasing with the increasing use of esophagogastroduodenoscopy. The most frequently found carcinomas of the duodenum include adenocarcinoma, carcinoid, lymphoma, and leiomyosarcoma. The symptoms of these carcinomas are often not specific so the diagnosis is often late, leading to a poor prognosis. Early diagnosis and proper therapy provide a good prognosis.  The case reported here representeda 52-year-old woman presented with hematemesis melena, anemia, jaundice, epigastric mass, right hypochondrial pain, and weight loss. From the esophagogastroduodenoscopy, the mass was found to obstruct half of the duodenum lumen and bleeding, which was easily triggered, was observed in the second part of the duodenum. CT scan revealed a mass in the head of the pancreas with gall bladder hydrops and obstruction of the intra and extra-hepatic billier system. After a Whipple operation Laparotomy, the histology showed papillary adenocarcinoma duodenum. Patients then underwen chemotherapy with 5 fluorouracil regimen. Patient's clinical condition is currently improving and no complaint is conveyed by the patient.

Abstract

Prototipe chamber zat radioaktif otomatis dilengkapi dengan sistem robotik telah berhasil dikembangkan dan diimplementasikan sebagai alat penunjang eksperimen fisika nuklir pada spektroskopi gamma. Prototipe ini terdiri dari chamber otomatis yang digunakan untuk mengukur spektrum zat radiasi, dinding chamber yang berfungsi sebagai penahan bahaya radiasi serta robot pemindah barang yang dipasang di dalam chamber. Mikrokontroler arduino uno R3 digunakan sebagai kontroler utama yang digunakan untuk mengatur pergerakan robot, fleksibilitas dan kemudahan dalam mengendalikan seluruh sistem di dalam chamber. Robot pemindah barang diprogram untuk memindahkan detektor dan sampel zat radioaktif secara presisi sesuai dengan posisi yang diinginkan. Selama praktikum menggunakan spektroskopi gamma, prototipe ini memudahkan mahasiswa dalam pengaturan sampel, efisiensi waktu praktikum dan biaya pembelian alat penunjang, meminimalisir bahaya paparan zat radioaktif serta menghilangkan resiko bahaya mekanik akibat terjepit shielding pembatas pada chamber manual. Penggunaan prototipe ini memberikan pengalaman praktikum yang lebih interaktif, efisien serta pemahaman mendalam tentang prinsip-prinsip spektroskopi gamma sambil mengembangkan keterampilan pemrograman dan pengendalian sistem bagi mahasiswa. Selain itu, pengembangan sistem lebih lanjut dari prototipe ini dapat melibatkan peningkatan fungsionalitas sistem robotik untuk mengakomodasi praktikum yang lebih kompleks dan variasi pengaturan eksperimen.

Abstract

Purpose — To analyze the impact of financial inclusion toward income distribution inequality in South Sumatra, Indonesia.Research method — The analysis method in this paper is panel regression model. This methodology is used to avoid bias specifications in the model. This paper applied three dimensions of financial which are financial penetration, access to financial services and use of financial services. The data was taken from the Financial Services Authority, Central Bank of Indonesia and the Central Statistics Agency. The data was time series from 2010-2017 and cross section from 9 rural and urban in South Sumatra, Indonesia.Result — The result showed that each district in South Sumatera has divergent degree of financial inclusion index. The degree of financial inclusion index in city area has a relatively higher financial index than hinterland areas. Based on the result of estimations, the impact of financial inclusion index on income inequality is positive and significant. This evidence proved that financial inclusion does not reduce income inequality in South Sumatra, Indonesia.Recommendation — Financial institutions are more motivated to lend to groups like farmers, the impoverished, and small and micro businesses. It is vital for the government to provide more fair financial services amongst regencies and cities.

Abstract

Memilih konsentrasi jurusan adalah hal penting dalam menentukan karir mahasiswa di masa depan, karena dari konsentrasi tersebut mahasiswa memiliki titik fokus dalam studinya, namun proses pemilihan konsentrasi masih memiliki kekurangan seperti kurang tepatnya kriteria, ketidaktahuan tentang konsentrasi yang dipilih dan kurang relevannya subjektivitas dalam pengambilan keputusan. Oleh karena itu dalam penelitian ini, diperlukan sebuah sistem pendukung keputusan pada Institut Teknologi Sapta Mandiri menggunakan metode AHP (Analytical Hierarchy Process) untuk memilih konsentrasi jurusan yang tepat dengan mempertimbangkan nilai KHS mahasiswa dan minat mereka sebagai acuan utama. Sistem pendukung keputusan dikembangkan menggunakan bahasa pemrograman PHP dan database MySQL. Setelah melalui proses perhitungan data dari metode AHP, keluaran berupa rekomendasi pilihan konsentrasi jurusan diberikan kepada mahasiswa yang bersangkutan melalui sistem pendukung keputusan. Sistem ini memberikan manfaat bagi mahasiswa dalam menentukan pilihan konsentrasi yang valid melalui perhitungan yang telah dilakukan.

Abstract

Breast cancer remains a leading cause of mortality among women worldwide, primarily due to delayed detection and a lack of early awareness. To address this issue, this study develops an advanced, thermal image-based breast cancer detection system that is non-invasive, radiation-free, and cost-effective, enhanced through the integration of artificial intelligence (AI) techniques. The proposed framework incorporates Attention U-Net for accurate segmentation of thermal breast images, K-Means Clustering to localize and isolate high-temperature regions suspected to be cancerous, and an EfficientNet-B7-based Convolutional Neural Network (CNN) for classification. To increase clinical reliability and transparency, the system employs Explainable AI (XAI) techniques using Local Interpretable Model-Agnostic Explanations (LIME), which provide visual interpretations of the model’s decision-making process. The dataset used in this research was obtained from the Database for Mastology Research (DMR) and consists of 2010 thermal images, including both healthy and abnormal cases. Preprocessing and segmentation effectively remove irrelevant areas and focus on the breast region, enhancing detection accuracy. Experimental evaluation indicates the proposed model achieves a training accuracy of 96.48% and a validation accuracy of 91.67%, with a recall of 91.95%, specificity of 91.43%, precision of 89.89%, and F1-score of 90.91%. These results highlight the system’s robust performance and generalizability. The LIME-generated superpixel visualizations help medical professionals better understand and validate the model's predictions, contributing to increased trust in AI-driven diagnostics. Overall, this research presents a reliable, explainable, and ethically grounded solution for early-stage breast cancer detection, demonstrating its strong potential for supporting clinical decision-making and future deployment in real-world healthcare settings.
