Abstract

Anemia is a disease related to the level of hemoglobin which is called red blood cells and causes a decrease in the level of oxygen that the body absorbs. Anemia is a disease that often occurs and occurs quite a lot in society. This study aims to determine the accuracy value of the certainty factor and forward chaining methods in an expert system for diagnosing anemia. This study designed an expert system by combining two methods, namely certainty factor and Android-based forward chaining. The use of the forward chaining method can make the system perform reasoning like an expert, then combine it with the certainty factor method with the aim that the system to be designed can measure the level of certainty of disease diagnosis. The results of this study are tests that have been carried out using 15 test data samples and produce a system accuracy value of 93.33%. Design using the certainty factor and forward chaining methods can work on expert systems in diagnosing anemia and shows the meaning that this system is feasible to use and is able to apply knowledge from experts to be able to diagnose anemia with a fairly accurate level.

Abstract

Paddy (Oryza sativa L.) is a cultivated crop that serves as the staple food source for the majority of the Indonesian population. East Java Province is one of the largest paddy-producing provinces in Indonesia. Jember Regency, as one of the paddy production centers in East Java, has a relatively high production level each year. However, there is currently no system available that clusters paddy data at the village level in the form of map-based visualization. This study aims to cluster the paddy harvest productivity of each village in Jember Regency based on the variables of planted area, harvested area, and paddy production for the years 2022 and 2023 using the K-Means Clustering algorithm and the Davies Bouldin Index (DBI). The data used in this study were obtained from the official publications of the Jember Regency Bureau of Statistics, covering a total of 248 villages. The clustering process was carried out by testing the number of clusters (k) from 2 to 10, which were then evaluated using DBI to determine the optimal number of clusters. The results show that the optimal number of clusters is 3, with a DBI value of 0.6053. This DBI value indicates that the quality of clustering of planted area, harvested area, and paddy production is considered good. The clustering results consist of 40 villages in Cluster 1, 105 villages in Cluster 2, and 103 villages in Cluster 3. The clustering results were implemented into a web- based Geographic Information System using the Flask Python framework and the Leaflet library to display an interactive map in GeoJSON format. This study is expected to provide benefits for the Jember Regency Bureau of Statistics, the community, and farmers in storing, managing, and providing information related to paddy production in Jember Regency.

Abstract

The method of memorizing the Qur'an Tawazun is a method that maximizes the use of the right brain and left brain, allowing a person to memorize, understand, and believe. Each category has several assessment points as a benchmark for the ability of students, which are used to overcome the level of failure of students in each category of learning the method of memorizing the Qur'an tawazun. The results of the evaluation of the learning of the tahfidz Islamic boarding school Daarul Huffadz Indonesia in 2020 were felt to be less than optimal, because the learning process was carried out simultaneously. This can be seen from the difference in scores that are quite different in each category of assessment. Based on the previous problem, it is necessary to group the results of the evaluation of learning the Qur'an memorization method. The goal is that every student gets maximum treatment and provides convenience for the institution, as well as teaching staff to carry out learning. The purpose of this study is to determine the optimum number of clusters as well as members of each cluster by measuring cluster performance using the Davies Bouldin Index (DBI) method and implementing the K-Means algorithm. The K-Means algorithm is a non-hierarchical data clustering method that is able to group large amounts of data, relatively quickly, and efficiently. This study uses 401 observational data and 12 attributes. From the calculation results, the optimal number of clusters lies in 2 clusters, with a Davies-Bouldin Index (DBI) value of 1.439. There are 26 members of cluster 1, and 375 members of cluster 2.

Abstract

Papaya leaf diseases, such as Papaya Ringspot Virus and Begomovirus, have a significant impact on papaya production and quality. Manual identification is often ineffective due to the visual similarity of symptoms. This study proposes a system for classifying papaya leaf diseases using a Convolutional Neural Network (CNN) with an ensemble learning method that aims to improve accuracy and provide accurate and stable predictions on new data that has not been seen during training. Three CNN architectures, namely VGG16, ResNet-34, and MobileNetV2, were trained individually with hyperparameter optimization using grid search. After training the individual models, the three models were combined (ensemble) using the soft voting method. The results showed that the best individual model was MobileNetV2, achieving 98% on all accuracy, precision, recall, and f1-score metrics, but the model with the most optimal performance was achieved by the ensemble model. The ensemble model achieved 99% accuracy, 98% precision, 99% recall, and 99% f1-score, these results demonstrate a significant improvement over the three individual trained models and outperform the ResNet-152v2 architecture reported in previous research

Abstract

Pengelolaan donasi masjid memerlukan sistem yang transparan, akuntabel, dan efisien guna meningkatkan kepercayaan jamaah serta mendukung optimalisasi pemanfaatan dana. Masjid Al-Qolam Universitas Muhammadiyah Jember saat ini masih menggunakan kotak amal fisik dan kanal donasi digital, namun pencatatan keduanya belum terintegrasi dan masih dilakukan secara manual. Kondisi ini berpotensi menimbulkan keterlambatan pelaporan, kesalahan pencatatan, serta keterbatasan dalam penyajian informasi keuangan secara real-time. Program Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan akuntabilitas pengelolaan donasi melalui penerapan kotak amal digital berbasis Internet of Things (IoT) serta pendampingan penggunaan sistem pencatatan terintegrasi. Metode pelaksanaan meliputi analisis kebutuhan, instalasi perangkat, integrasi sistem dashboard, pelatihan kepada pengurus, serta monitoring dan evaluasi tingkat adopsi teknologi. Hasil kegiatan menunjukkan bahwa sistem kotak amal digital mampu mencatat donasi tunai secara otomatis dan menampilkan data pada dashboard secara real-time. Selain itu, pengurus masjid telah mampu mengoperasikan sistem secara mandiri setelah dilakukan pendampingan. Program ini memberikan kontribusi dalam meningkatkan transparansi, efisiensi, dan akuntabilitas pengelolaan donasi masjid. Kegiatan ini diharapkan dapat menjadi model inovasi pengelolaan donasi berbasis teknologi yang dapat direplikasi pada masjid atau lembaga filantropi lainnya

Abstract

Conventional hydroponic fodder production relies on manual, non-predictive monitoring, complicating feed planning. This study presents a low-cost edge-computing platform for hydroponic fodder built on a repurposed Linux set-top box (STB), integrated with an environment-driven growth model through a Hardware-in-the-Loop (HIL) scheme. The STB edge node hosts the MQTT broker, time-series database, and monitoring dashboard, while temperature and light are acquired in real time by SHT30 and BH1750 sensors via an ESP32. No physical load cell is used; biomass is therefore simulated by a logistic ordinary differential equation (ODE) with temperature-dependent rate r(T) and light-dependent carrying capacity K(L), driven by real environmental data recorded over a single 10-day cultivation cycle (20-29 June 2026, with interpolated gaps flagged). The model is calibrated to two empirical anchor points (1 kg at day 0, 13 kg reference at day 10); this agreement is reported as a calibration/consistency check rather than out-of-sample predictive validation. Sensitivity analysis shows the endpoint is dominated by carrying capacity (S = 0.96), and a fourth-order Runge-Kutta solver deviates only 0.007 kg from a reference integrator. Crucially, the complete model is executed on the STB itself using only the Python standard library: a full 10-day simulation completes in 46.6 ms (43.7 microseconds per RK4 step) within 15 MB of RAM at a stable 50 C, demonstrating that the edge node alone suffices without cloud computation.
