Abstract

Diabetes Melitus Tipe 2 (DMT2) merupakan salah satu permasalahan kesehatan utama di wilayah perkotaan dan banyak dialami oleh kelompok usia produktif, termasuk masyarakat di Kelurahan Duri Kepa. Rendahnya pemahaman masyarakat, khususnya ibu-ibu PKK, mengenai deteksi dini diabetes menjadi latar belakang pelaksanaan kegiatan Pengabdian kepada Masyarakat (PkM) yang berfokus pada sosialisasi aplikasi pendeteksi risiko diabetes berbasis teknologi lie detection. Kegiatan yang dilaksanakan pada 10–31 Oktober 2025 ini meliputi tahap persiapan, pelaksanaan, evaluasi, dan tindak lanjut, dengan melibatkan partisipasi aktif masyarakat. Aplikasi yang diperkenalkan memanfaatkan analisis respons pengguna untuk mengidentifikasi potensi risiko diabetes dan memberikan kategori hasil berupa Tipe 1, Tipe 2, atau Tidak Terdeteksi. Hasil yang diberikan bukan merupakan diagnosis medis, tetapi indikator awal yang berfungsi sebagai pengingat agar masyarakat lebih memperhatikan pola makan, aktivitas fisik, dan gaya hidup sehat. Evaluasi kegiatan menunjukkan adanya peningkatan pengetahuan dan kesadaran masyarakat terhadap deteksi dini diabetes serta pemanfaatan teknologi informasi dalam bidang kesehatan. Program ini memberikan dampak positif dalam meningkatkan literasi kesehatan digital dan menunjukkan penerapan inovasi teknologi informasi untuk mendukung upaya pencegahan penyakit tidak menular di lingkungan masyarakat.

Abstract

Good water quality is crucial for living things, including temperature, pH, and TDS, which are constantly changing due to various factors. These three water parameters are crucial for maintaining water quality within a certain threshold to ensure that an ecosystem meets specified standards. Measuring water quality is essential to anticipate these changes as desired. Internet of Things (IoT) technology allows continuous monitoring of water parameters at any time and can be accessed anywhere with a network connection via computer or smartphone. In this proposed research, an IoT-based system based on ESPHome will be developed for water quality measurement in aquarium water and its ecosystem. The proposed research detects, records, and displays water pH and TDS parameters, including temperature, using an ESP8266 microcontroller. The system utilizes sensors to detect water parameters; the system utilizes an ESP8266 microcontroller and a WiFi connection that sends data to a cloud-based server with a Homeassistant dashboard. The research results are well-functioning in both hardware and software and are easily accessible.

Abstract

This study aimed to develop an AI-based image classification model using transfer learning methods to identify seven types of anti-inflammatory plant leaves commonly used in traditional medicine. The novelty of this research lies in approach to integrating Canny Edge detection and Gamma Correction with the ResNet50 architecture for multimodal fusion. The class plants, including Aloe Vera, Annona Muricata, Centella Asiatica, Muntingia Calabura, and Ocimum Basilicum, are known for their therapeutic properties and bioactive compounds. A dataset consisting of 350 images per species was collected, with images divided into training (70%), validation (20%), and testing (10%) sets. Data augmentation techniques such as rotation, flipping, and zooming were applied to improve model generalization. To enhance classification performance, pre-trained convolutional neural network (CNN) models, including ResNet50 and VGG16, were employed for transfer learning. The study also integrated image processing techniques, such as the Laplacian Filter, Canny Edge, and Gamma Correction, to extract additional features and improve the model’s accuracy. Among the different configurations tested, the combination of Canny Edge and Gamma Correction with ResNet50 yielded the best results, achieving a training accuracy of 89.3%, validation accuracy of 88.1%, and test accuracy of 87.0%. In contrast, the use of Laplacian Filter and Canny Edge with ResNet50 led to lower performance, suggesting that multimodal fusion of certain feature extraction methods could enhance classification accuracy. This research highlighted the potential of AI-driven approaches in the classification of medicinal plant leaves and offered a more efficient, accurate method for identifying anti-inflammatory plants used in traditional medicine.
