SIMULATION-DRIVEN METHOD FOR WATER COVERAGE MONITORING FROM MULTI-SENSOR SATELLITE IMAGERY
type: item
description: Monitoring water coverage in intertidal zones is challenging due to the lack of satellite sensors that simultaneously provide both high spatial and high temporal resolution. Landsat offers detailed spatial information but is limited by its 16-day revisit cycle, whereas Himawari-8 provides frequent observations but at coarse spatial scales. Existing multi-sensor fusion approaches, such as STARFM and ESTARFM, attempt to bridge this gap but rely on the assumption of linear or abrupt land cover changes, which is inadequate for capturing the gradual and non-linear dynamics of tidal environments. This study proposes a simulation-driven method to enhance water coverage monitoring by generating reference images that represent varying water height conditions. The approach integrates normalized Landsat OLI and Himawari-8 AHI imagery with digital elevation and tidal models to interpolate Modified Normalized Difference Water Index (mNDWI) values. Through linear interpolation, synthetic reference images are produced for low, medium, and high-water height scenarios, filling temporal gaps and providing additional input for fusion-based monitoring. Results from the Hsiang-Shan Wetland demonstrate that simulated reference images contribute more significantly to accurate water mapping than Himawari-8 data alone. The method improves temporal continuity, enhances the representation of tidal dynamics, and reduces discrepancies in fused outputs. Although the accuracy depends on DEM and tidal model quality, the findings highlight the potential of simulation-driven approaches to strengthen water monitoring frameworks. This method can be extended to support applications in flood mapping, wetland management, and coastal conservation.

Analisis Penggunaan Fluxion portable Untuk Menguji Wi-Fi dengan Keamanan WPA/WPA2
type: item
description: Dengan kemudahan yang ditawarkan oleh jaringan Wi-Fi, kejahatan siber berupa pembobolan password Wi-Fi menjadi semakin marak. Studi ini bertujuan untuk mengevaluasi efektivitas penggunaan fluxion portable sebagai alat uji keamanan Wi-Fi yang dilindungi WPA/WPA2. Penelitian dilakukan pada router ZTE-F609 menggunakan pendekatan action research untuk memberikan pemahaman yang lebih mendalam mengenai efektivitas metode ini. Fluxion portable bekerja dengan memanfaatkan teknik social engineering, di mana penyerang menciptakan jaringan palsu (rogue AP) yang menyerupai jaringan asli. Melalui rekayasa sosial ini, pengguna tanpa sadar memasukkan kata sandi mereka pada jaringan palsu tersebut. Penelitian ini menunjukkan bahwa fluxion portable terbukti efektif dalam memperoleh kata sandi Wi-Fi melalui manipulasi psikologis yang umumnya tidak disadari pengguna. Hasil ini mengindikasikan risiko signifikan yang dihadapi pengguna Wi-Fi, terutama di lingkungan yang tidak memiliki perlindungan tambahan. Sebagai langkah mitigasi terhadap potensi serangan menggunakan fluxion portable, pengguna disarankan untuk menyembunyikan jaringan Wi-Fi mereka dari publik atau menggunakan router dengan fitur keamanan tambahan, seperti whitelist. Rekomendasi ini diharapkan dapat meningkatkan keamanan jaringan Wi-Fi serta kesadaran pengguna terhadap potensi ancaman yang ada.

Optimasi Segmentasi Kepala Janin Berbasis U-Net Melalui Preprocessing Citra USG
type: item
description: Pengukuran Lingkar Kepala atau Head Circumference (HC) janin melalui citra Ultrasonografi (USG) merupakan parameter biometrik krusial untuk mengestimasi usia kehamilan dan memantau laju pertumbuhan janin. Namun, interpretasi citra USG sering terkendala oleh karakteristik speckle noise, kontras rendah, dan batas tepi objek yang kabur, yang menyulitkan proses segmentasi otomatis. Penelitian ini bertujuan untuk mengoptimalkan kinerja arsitektur U-Net dengan backbone ResNet-34 dalam mensegmentasi kepala janin melalui penerapan teknik preprocessing dan augmentasi data. Metode yang diusulkan mengintegrasikan Anisotropic Diffusion untuk mereduksi noise dan CLAHE (Contrast Limited Adaptive Histogram Equalization) untuk mempertegas fitur batas objek, serta augmentasi geometri (rotasi, flip) dan median blur. Model dilatih menggunakan 799 data latih dan validasi dengan rasio 80:20 dan 200 data uji yang bersumber dari dataset publik. Hasil pengujian menunjukkan bahwa penerapan preprocessing mampu meningkatkan akurasi segmentasi secara signifikan dibandingkan tanpa optimasi. Skor Intersection over Union (IoU) meningkat dari 0.9440 menjadi 0.9526, dan Dice Similarity Coefficient (DSC) 0.9757. Meskipun visualisasi preprocessing mempertegas artefak tertentu, hal ini terbukti membantu model dalam membedakan foreground dan background dengan lebih baik. Berdasarkan hasil segmentasi, estimasi biometrik dilakukan menggunakan metode ellipse fitting. Penelitian ini menyimpulkan bahwa U-Net dengan optimasi preprocessing Anisotropic Diffusion dan CLAHE memiliki potensi besar sebagai alat bantu bagi tenaga medis untuk mempercepat pengukuran biometrik dengan tetap memerlukan verifikasi klinis.

RANGKUMAN PENGGUNAAN METODE MARKER BASED TRACKING DAN MARKERLESS PADA APLIKASI AUGMENTED REALITY
type: item
description: Teknologi Augmented Reality mengalami perkembangan pesat dengan dua pendekatan pelacakan utama yaitu metode marker based tracking dan markerless. Kajian literatur ini menganalisis sebelas implementasi penelitian yang dipublikasikan antara tahun 2020 hingga 2025 untuk mengevaluasi karakteristik performa, keunggulan, serta keterbatasan kedua metode pelacakan pada berbagai domain aplikasi. Metode marker based tracking mendemonstrasikan akurasi superior dengan tingkat kesalahan di bawah tiga persen dan stabilitas optimal pada lingkungan terkontrol, mencapai tingkat keberhasilan 72,2 hingga 77,8 persen pada berbagai perangkat. Namun terjadi degradasi performa pada jarak ekstensif dan kondisi pencahayaan spesifik. Sebaliknya, metode markerless menawarkan fleksibilitas eksepsional dengan tingkat keberhasilan mencapai 94,4 persen dan adaptabilitas luar biasa terhadap kondisi lingkungan beragam tanpa memerlukan penanda fisik. Metode ini terbukti sangat efektif untuk aplikasi medis, desain interior, pendidikan anatomi, dan manufaktur pintar. Tantangan utama meliputi ketidakstabilan spasial hologram pada pengaturan kompleks dan kebutuhan komputasi lebih tinggi. Inovasi yang mengombinasikan absolute pose regressor dengan visual-inertial odometry telah mereduksi kesalahan hingga lima puluh persen dengan kecepatan inferensi delapan puluh milidetik. Pemilihan metode harus mempertimbangkan kebutuhan akurasi, kondisi lingkungan operasional, keterbatasan perangkat keras, dan kompleksitas implementasi untuk mengoptimalkan efektivitas aplikasi AR.

ETIKA PENGGUNAAN CHATGPT DALAM PENDIDIKAN DAN EKONOMI ISLAM: TINJAUAN MAQASID AL-SHARI’AH
type: item
description: Abstract This study examines the ethical implications of ChatGPT usage in Islamic higher education, especially within the domains of Islamic economics and Sharia-based finance. As generative AI tools gain popularity among students and educators, they present both educational support potential and ethical challenges - including risks of plagiarism, diminished critical thinking, religious misinformation, and excessive technological dependence. Adopting a qualitative exploratory approach, this research integrates library studies with expert interviews involving scholars in Islamic economic thought and Islamic banking. To enrich the analysis, a machine learning-based text similarity comparison was conducted between ChatGPT’s responses and expert opinions on selected topics. This comparative analysis quantitatively measured content alignment, revealing high levels of similarity (85–90%) in Sharia banking discourse and over 90% in Islamic economic fundamentals. The study employs both thematic analysis and normative evaluation grounded in Maqasid al-Shari’ah, focusing on the preservation of religion (ḥifẓ al-dīn), upholding intellectual integrity (ḥifẓ al-ʿaql), and protection of the soul/life (ḥifẓ al-nafs). The results demonstrate that ChatGPT can be a valuable academic support tool, yet it must be used with critical supervision and scholarly validation. The paper concludes by emphasizing the urgent need for Islamic higher education institutions to develop AI ethics guidelines that are contextually rooted in Sharia principles, ensuring that AI integration enhances rather than compromises Islamic educational integrity.

Comparative Evaluation of NDVI-Based Vegetation Classification Using Rule-Based Thresholding and Random Forest Models
type: item
description: This study aims to compare vegetation classification performance using NDVI derived from Sentinel-2A and Landsat 8 satellite imagery through two different approaches: rule-based classification and machine learning with the Random Forest algorithm. The rule-based approach applies a fixed NDVI threshold of 0.45 to distinguish vegetation and non-vegetation areas. In contrast, the Random Forest model was trained using 70% of the labeled data and tested on the remaining 30%, with NDVI values from both satellite sources as input features. The evaluation results show that the Random Forest model achieved perfect classification accuracy (100%). However, this may be due to using the same labeled dataset for both training and validation, which can lead to overfitting. On the other hand, the rule-based classification yielded an accuracy of 79.7%. This lower performance is likely caused by several factors, including the resolution differences between Sentinel-2 and Landsat 8 imagery, and the subjectivity involved in selecting the NDVI threshold value. The manual threshold setting may lead to bias and a higher number of misclassified pixels. Therefore, while rule-based methods are simple and interpretable, they are less robust. Machine learning approaches, such as Random Forest, offer more flexible and accurate classification when supported by properly separated training and validation datasets.

DINAMIKA PENGGUNAAN TEKNOLOGI DALAM PEMBELAJARAN PASCA PANDEMI: PERSPEKTIF MAHASISWA DAN DOSEN
type: item
description: Penelitian ini bertujuan untuk menganalisis perubahan pola penggunaan teknologi dalam pembelajaran sebelum, selama, dan setelah pandemi, serta faktor-faktor yang memengaruhi penurunan penggunaan teknologi pascapandemi di kalangan mahasiswa dan dosen. Pendekatan kuantitatif dan kualitatif digunakan untuk mengumpulkan data melalui kuesioner dan wawancara terhadap 115 mahasiswa pendidikan bisnis dan 8 dosen dari berbagai prodi. Hasil penelitian menunjukkan bahwa sebelum pandemi, 40% responden menggunakan teknologi secara moderat hingga intensif, yang meningkat menjadi 95% selama pandemi, tetapi menurun kembali menjadi 55% setelah pandemi. Penurunan ini disebabkan oleh beberapa faktor, seperti digital fatigue (88% mahasiswa dan 87% dosen merasa lelah), preferensi pembelajaran tatap muka (86% mahasiswa merasa lebih nyaman), serta keterbatasan infrastruktur kampus (83% responden mengeluhkan fasilitas yang kurang memadai). Selain itu, kebijakan institusi yang belum sepenuhnya mendukung integrasi teknologi juga menjadi tantangan. Meskipun demikian, mahasiswa dan dosen menyatakan bahwa teknologi tetap penting sebagai pelengkap pembelajaran hybrid, meskipun integrasinya belum optimal. Temuan ini memberikan wawasan penting bagi institusi pendidikan dalam merancang kebijakan dan strategi pembelajaran berbasis teknologi yang lebih efektif di masa depan.

FUSING SATELLITE DATA TO MONITOR SEA LEVEL CHANGES: A DEM-BASED NEAREST NEIGHBOR APPROACH
type: item
description: High spatial and temporal resolution satellite imagery is essential for monitoring rapid environmental changes at finer scales. However, no single satellite currently provides images with both high spatial and temporal resolution. To overcome this limitation, spatiotemporal image fusion algorithms have been developed to generate images with improved spatial and temporal detail. Water level monitoring is also crucial for managing natural hazards like floods and tsunamis, but remote sensing satellites face challenges in continuous monitoring due to either low spatial or temporal resolution. For instance, while Landsat 8, with a spatial resolution of 30 meters, has been used for water level detection, it cannot capture fast-changing events because of its low temporal resolution. Conversely, the Advanced Himawari Imager (AHI) 8 offers observations every 10 minutes but has a coarse spatial resolution, limiting its ability to map sea level changes accurately. This study focuses on integrating Landsat and AHI imagery to monitor local and dynamic sea level changes. The process involves calibrating images from the study area to surface reflectance and co-registering them. The Normalized Difference Water Index (NDWI) is calculated from both Landsat and Himawari-8 images, serving as input for image fusion. In the previous study, the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) is used for image fusion. In this study we use the application of Spatial Temporal Adaptive Algorithm for Mapping Reflectance Change (STAARCH) for the image fusion step. Since traditional methods are influenced by land cover changes, this study proposes a method called DEM-based Nearest Neighbor to select appropriate land cover maps for image fusion. Evaluation results demonstrate that this approach can produce accurate water coverage maps with both high spatial and temporal resolution.

Dataset terdiri dari gambar-gambar tiga kelas utama anggrek: Anggrek Bulan (Phalaenopsis), Anggrek Dendrobium, dan Anggrek Tanah (Paphiopedilum), dengan sekitar 40 gambar per kelas. Gambar-gambar tersebut dikumpulkan dari berbagai sumber yang tepercaya seperti diperoleh di Dinas Ketahanan Pangan dan Tanaman Pangan dan Hortikultura Provinsi Lampung serta Dinas Ketahanan Pangan, Pertanian dan Perikanan Kota Metro dan para UMKM toko bunga di Provinsi Lampung serta berbagai sumber termasuk database publik, situs web hortikultura, dan koleksi pribadi, untuk mencakup variasi visual dalam setiap kelas. Proses pengumpulan data melibatkan pengambilan dan pengunduhan gambar beresolusi tinggi, pengkategorian dan pelabelan, serta pra-pemrosesan untuk meningkatkan kualitas gambar. Dataset kemudian dibagi menjadi data pelatihan dan pengujian dalam rasio 70:30 untuk melatih dan mengevaluasi performa model. Dengan memanfaatkan teknik lanjutan dalam pengumpulan data, pra-pemrosesan, dan analisis, penelitian ini bertujuan untuk mengembangkan model yang tangguh mampu mengklasifikasikan spesies bunga anggrek secara akurat berdasarkan karakteristik visualnya.

DEVELOPMENT OF THE ANDROID-BASED SINGLE-PLAYER GAME COOKING CHAOS
type: item
description: Cooking is the process of preparing food from its raw state until it is ready to be served, using heat to make it easier for the body to digest. However, nowadays, many teenagers lack an understanding of how to cook due to limited practice and a tendency to buy food from outside, which is considered more convenient. High levels of activity outside the home also contribute to the decreasing frequency of cooking among teenagers. Additionally, the convenience offered by food delivery applications, coupled with various attractive promotions, further contributes to the decline in interest in cooking. To address this issue, an educational single-player game application based on Android was developed, utilizing Unity 3D as the game engine and Blender for 3D object modeling. This application is designed to provide a more detailed cooking experience by offering 11 recipes that users can learn. Moreover, there is a mini-game in the form of a quiz to test users' understanding of the cooking process. Testing results show that this application successfully increased users' interest in learning to cook by 80.3%.
