Abstract

Segmentation of digital images of fish is an important challenge in image processing in the field of marine biology and aquaculture. Extraction of fish shape features through image segmentation can improve accuracy in species identification and fish population monitoring. The U-Net method, which is based on deep learning, has been proven effective in medical image segmentation and is beginning to be applied in fish image segmentation. This study aims to develop a fish digital image segmentation method using U-Net architecture for accurate and efficient fish shape feature extraction. The dataset used consists of 500 fish images of various shapes and sizes collected from various sources. The fish images were processed using a U-Net artificial neural network, which was trained and tested to obtain the best segmentation results, with evaluation using Intersection over Union (IoU). The segmentation results show that the U-Net method can produce precise segmentation, with a high degree of accuracy in extracting fish shape features. Evaluation of the segmentation metrics resulted in an IoU value of 0.88, indicating excellent performance in distinguishing the fish object from the background and accurately mapping the fish shape. The fish digital image segmentation method using U-Net is effective for fish shape feature extraction and can be applied in fish species identification and aquatic ecosystem monitoring.

Abstract

Conventional campus introductions are often limited in providing an immersive experience to prospective students, especially for those who cannot attend in person. This encourages the need for technology-based solutions that can overcome these limitations. This research develops a WebVR-based VT-UNUJA application as a campus introduction media that offers an interactive experience with 360-degree panoramic image features, hotspot descriptions, navigation, and voice-over. The purpose of this research is to create an application that can increase user understanding of campus locations and facilities more efficiently and easily accessible. The test results show that this application is effective in improving user understanding, with a high level of satisfaction with the ease of use and interactivity of the application. The benefits of this research are to contribute in improving campus professionalism in presenting information digitally, as well as providing innovative alternatives for other educational institutions in supporting the orientation process for prospective students.

Abstract

Informatics study program at Nurul Jadid University does not have a general concentration of knowledge, so that sometimes the selection of elective courses by students is not quite right. This study aims to classify the concentration of knowledge with a data mining approach which can then be used as a recommendation for selecting elective courses by students. In this study, we implement a machine learning algorithm to provide recommendations to students regarding what interests are more suitable to be taken based on the values ​​of prerequisite courses in previous semesters. Student data was obtained from the Head of the Center for Data and Information Systems (PDSI) at Nurul Jadid University with 70 student data from Nurul Jadid University batch 2018. The machine learning algorithm used is Neural Network with Python programming language, the tools used are Google Collab. At the beginning of data collection, then pre-processing is carried out to prepare the dataset in order to get good results, and model training is carried out. After training on the model, then further testing is carried out on the model to determine the performance of the model. The result of the accuracy value in the training model process is 0.83 or 83% and the accuracy of the test data is 0.79 or 79%.

Abstract

Perkembangan transformasi digital yang semakin pesat telah digitalisasi mendorong institusi pendidikan mengadopsi sistem Penerimaan Mahasiswa Baru (PMB) berbasis web. Namun, sistem ini rentan terhadap berbagai serangan siber seperti SQL Injection, XSS, dan bot attack. Penelitian ini bertujuan mengembangkan keamanan berbasis Laravel yang mampu mendeteksi dan menangkal ancaman tersebut secara otomatis. Metode yang digunakan adalah Research and Development (R&D), melalui tahap studi pendahuluan, perancangan, pengembangan, pengujian, dan evaluasi. Middleware yang dikembangkan memiliki fitur validasi input, deteksi pola serangan berbasis regex, pembatasan permintaan, logging aktivitas, serta geo-tracking. Hasil pengujian menunjukkan middleware mampu mendeteksi dan memblokir seluruh simulasi serangan dengan tingkat keberhasilan 100%, tanpa menurunkan performa sistem secara signifikan. Evaluasi pengguna juga menunjukkan peningkatan kepercayaan terhadap sistem PMB yang lebih aman dan tangguh. Penelitian ini membuktikan bahwa integrasi keamanan berbasis dapat menjadi solusi efektif untuk melindungi aplikasi web akademik dari ancaman siber.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PKM) di Desa Karanganyar bertujuan meningkatkan literasi digital masyarakat, khususnya dalam penggunaan media sosial yang bijak dan bertanggung jawab. Program ini penting karena tingginya penggunaan media sosial belum diimbangi pemahaman tentang keamanan, etika, dan dampak negatif seperti hoaks dan cyberbullying. Edukasi ini dirancang untuk mewujudkan Desa Karanganyar sebagai "Desa Smart People" yang adaptif terhadap perkembangan teknologi. Analisis situasi menunjukkan rendahnya literasi digital dan minimnya edukasi formal di desa tersebut. Untuk mengatasi tantangan ini, diterapkan metode berupa ceramah, diskusi interaktif, simulasi praktis, serta pendampingan pasca-program. Keberhasilan kegiatan ini didukung oleh partisipasi aktif pemerintah desa dan tokoh masyarakat. Hasil program menunjukkan peningkatan signifikan dalam pemahaman peserta terkait literasi digital, bahaya hoaks, dan pentingnya menjaga privasi. Perubahan perilaku masyarakat terlihat dalam sikap yang lebih selektif terhadap informasi yang disebarkan. Program ini juga mendorong pemanfaatan media sosial untuk promosi produk lokal dan pariwisata desa. Secara keseluruhan, program ini meletakkan dasar transformasi digital di Desa Karanganyar dan dapat direplikasi untuk membangun masyarakat yang cerdas teknologi di desa lain.
