Abstract

This study aims to develop an accurate and efficient empty parking slot detection model to assist users in finding parking spaces. The developed model utilizes YOLOv11 as a pretrained model and demonstrates excellent performance with a precision of 99%, recall of 99%, and a Mean Average Precision (mAP) of 99%. These results validate the model's ability to accurately detect empty parking slots with 100 training epochs. Additionally, the model operates in real-time with a frame rate of 25 frames per second (FPS)

Abstract

In the field of disease diagnosis with ophthalmic aids, automatic segmentation of the retinal optic disc is required. The main challenge in OD segmentation is to determine the exact location of the OD and remove noise in the retinal image. This paper proposes a method for automatic optical disc segmentation on color retinal fundus images using histogram analysis. Based on the properties of the optical disk, where the optical disk tends to occupy a high intensity. This method has been applied to the Digital Retinal Database for Vessel Extraction (DRIVE)and MESSIDOR database. The experimental results show that the proposed automatic optical segmentation method has an accuracy of 55% for DRIVE dataset and 89% for MESSIDOR database

Abstract

Interactive information media has many benefits in the process of conveying information, one of which is by visualizing objects in real time. Socialization activities at the Rensing Health Center in conveying information on gastric diseases still do not use visual aids as a medium for delivering counseling. Therefore, this study aims to develop information media in the form of an android application by utilizing Augmented reality (AR) technology to show the stomach acid process in real time which is visualized in the form of 3D animation. The method used in application development is Multimedia Development Life Cycle (MDLC). Where this method consists of 6 (six) stages of development, namely concept, design, Material Collecting, Assembly, testing and distribution. The results of this study are a visualization application of gastric acid reflux using mobile-based augmented reality built using Unity 2017.3.1f1 and the Vuforia Software Development Kit (SDK), with several stages of the process, namely entering the database and all assets into unity, lighting, creating a user interface, scripting and finally build the application to the android platform Based on the results of application trials that have been carried out at the Rensing Health Center, it shows that mobile-based augmented reality has succeeded in assisting officers in visualizing gastric acid reflux. The satisfaction of health officers in using the application can be seen from the results of the questionnaire to the respondents, where the results of the questionnaire 32% stated strongly agree, 59% agreed, 6% disagreed and 2% disagreed.

Abstract

Background: The rapid development of technology has driven progress across various sectors, including the property industry in Indonesia. However, property data integration on Lombok Island still faces challenges due to the diversity of attribute naming, which hinders efficient information retrieval.Objective: This study aims to integrate four property databases (Saduthama, Salva, SJP, and Garden View) using a schema matching method based on linguistic and constraint approaches.Methods: The linguistic approach is used to identify similarities between attributes, even when their names differ, using the Bigram technique, which proved effective in identifying attribute similarities with a threshold of 0.7. Meanwhile, the constraint approach evaluates the compatibility of attributes based on additional criteria such as data type, attribute length, null values, and uniqueness, ensuring that the integrated attributes work compatibly. The integration process includes preprocessing, generalization, and attribute matching.Result: The evaluation results show precision (P), recall (R), and F-measure of 90%, with an average accuracy of 84%.Conclusion: This result outperforms previous studies that achieved 100% precision, 60% recall, and 75% F-measure.

Abstract

Kegiatan pendampingan dan pelatihan desain grafis ini bertujuan untuk meningkatkan keterampilan siswa SMK Islam Terpadu Darul Mujahidin Lombok Tengah dalam bidang desain grafis, khususnya pada pembuatan produk percetakan seperti brosur, kartu nama, pamflet, dan kemasan produk. Pelatihan dilaksanakan sebagai bentuk penguatan kompetensi keahlian dan kesiapan siswa menghadapi dunia industri kreatif yang semakin berkembang pesat. Peserta mendapatkan manfaat dari pelatihan ini yaitu memperoleh pengetahuan dan keterampilan praktis di bidang desain grafis, khususnya dalam pembuatan produk percetakan seperti brosur, pamflet, kartu nama, dan siswa dapat menyalurkan ide dan kreativitasnya secara visual, serta belajar menyusun desain yang komunikatif dan menarik. Metode pelatihan meliputi pemberian materi dasar desain grafis, pengenalan software desain seperti Canva dan CorelDRAW, serta praktik langsung pembuatan desain cetak. Kegiatan dilakukan secara bertahap, mulai dari teori dasar desain (elemen & prinsip), tipografi, warna, hingga proses produksi desain siap cetak. Selain itu, diberikan pula sesi konsultasi dan evaluasi karya untuk mengasah kreativitas dan kerapian teknis. Hasil pelatihan menunjukkan bahwa peserta mengalami peningkatan pemahaman dan keterampilan teknis dalam membuat desain grafis yang sesuai standar industri percetakan. Pelatihan ini diharapkan mampu menjadi bekal awal bagi siswa dalam mengembangkan kemampuan desainnya secara mandiri dan profesional, serta membuka peluang usaha mandiri di bidang percetakan.

Abstract

Hypertensive retinopathy is a type of eye disease where microvascular changes occur in the retina experienced by high blood pressure sufferers. The arterial and venous ratio (AVR) in the retina of the eye is an indicator used to determine the presence of high blood pressure, which is measured by the ratio of the width of the retinal arteries and veins. Traditionally, ophthalmologists use fundus images or retinal images of the eye to diagnose hypertensive retinopathy's physical symptoms and determine the phase of evolution. Still, traditional methods have limitations because, in the case of borderline stages, the early symptoms of hypertensive retinopathy will be difficult to identify manually, so they are often ignored. Referring to these problems, early diagnosis is needed for accurate prevention and treatment of hypertensive retinopathy. Based on the abovementioned issues, this service activity aims to implement a hypertensive retinopathy disease detection model using a local dataset from a regional general hospital in West Nusa Tenggara (NTB). It will compare the model detection results with those of three eye disease experts. Classification model testing results using the Messidor training and NTB Regional Hospital datasets. In models using the Messidor training dataset, the highest accuracy is a comparison with the results of the most senior expert's observations. The results of the classification model are only a tool to assist ophthalmologists in diagnosing hypertensive retinopathy, while the final decision remains with the expert or ophthalmologist.
