Abstract

This study designs and implements an Internet of Things (IoT)-based system to minimize cigarette smoke exposure in enclosed spaces. The system uses an MQ-2 sensor integrated with an ESP32 microcontroller, along with automatic fan-based filtration and a HEPA + activated carbon filter. The method used is research and development (R&D) through the design, implementation, testing, and analysis stages. The results show that the MQ-2 sensor is able to detect cigarette smoke concentrations in real time and transmit data to the Thinger.io platform. An LED traffic light indicator system is used to show air quality status, while an automatic relay controls the fan to speed up the filtration process. The trial showed that the system was able to reduce cigarette smoke levels by more than 70% and provide warning notifications to users. Thus, this system has the potential to increase awareness of active smokers and protect passive smokers in the household environment.

Abstract

This study aims to develop a mathematical model based on Integer Linear Programming (ILP) to map unmastered mathematical topics among senior high school students according to the cognitive domains of Bloom's Taxonomy, namely Knowledge (C1), Comprehension (C2), and Application (C3). The research method employed a quantitative approach, utilizing test result data from a 48-item instrument covering 16 mathematical subtopics, administered to 147 twelfth-grade students in the Natural Science program. The data were analyzed using LINDO 6.1 software to generate a profile of student mastery for each subtopic and cognitive domain. The results indicate that student mastery was generally higher in the Knowledge (C1) domain, with eight subtopics achieved, compared to the Comprehension (C2) domain with six subtopics and the Application (C3) domain with five subtopics. Out of the total 48 test items, only 19 items (39.6%) were mastered by the students, while 29 items (60.4%) were not. The Equations and Inequalities (X2) subtopic was the only material not mastered across all three domains. These findings suggest the need for learning strategies that place greater emphasis on strengthening conceptual understanding and contextual application. The application of the ILP model in this study proves effective as a diagnostic tool for identifying student weaknesses in a detailed and objective manner, thereby serving as a reference for teachers in designing targeted remedial programs. Furthermore, this model has the potential to be replicated in other schools to continuously monitor the development of student proficiency.

Abstract

Kegiatan Projek Kepemimpinan yang diadakan oleh Peneliti Universitas Muhammadiyah Sumatera Utara (UMSU) di Panti Asuhan Putera Muhammadiyah Medan berfokus pada pemanfaatan barang bekas untuk membuat alat peraga bangun ruang. Banyak anak di panti asuhan ini adalah seorang pelajar yang sering menganggap matematika sulit dan abstrak. Oleh karena itu, alat peraga visual diperlukan agar siswa dapat memahami materi dengan lebih baik. Dalam pembelajaran matematika, terutama pada materi bangun ruang, alat peraga sangat penting. Visualisasi bangun ruang tidak hanya bisa dilakukan melalui gambar di papan tulis, tetapi juga membutuhkan bentuk nyata dari bangun ruang. Dalam proyek ini, bahan utama yang digunakan adalah koran dan kardus. Barang tersebut mudah ditemukan di sekitar Panti Asuhan Putera Muhammadiyah Medan. Selain membuat alat peraga, peneliti juga merancang produk fungsional dengan nilai jual, seperti celengan, tempat tisu, tepak sirih, vas bunga, dan tempat pulpen yang berguna bagi anak-anak panti asuhan. Metode yang digunakan dalam pelaksanaan kegiatan pelatihan ini menggunakan pendekatan kualitatif dengan melakukan kegiatan observasi dan workshop Praktis, di mana peserta didik terlibat langsung dalam pembuatan alat peraga secara kelompok. Setelah melaksanakan tiga sesi pelatihan, anak-anak panti asuhan menunjukkan ketertarikan yang lebih besar terhadap matematika dan semakin kreatif dalam memanfaatkan barang bekas menjadi produk yang bermanfaat yang memiliki nilai fungsional dan nilai jual.

Abstract

Blood stock availability at the Blood Donation Unit (UDD) PMI Langkat Regency is often disrupted due to unpredictable demand and reliance on voluntary donors, leading to risks of shortages or surpluses, especially for certain blood groups. This study applies a data mining method using the Single Moving Average (SMA) approach to predict the demand for blood bags based on blood groups (A, B, AB, and O) over the past year. The forecasting process calculates the average demand over a specific period and measures accuracy using MAPE, MSE, and MAD. The results show that the SMA method provides reasonably accurate predictions, with blood group O having the highest average demand of 161 bags per month, followed by blood groups A, B, and AB. An average MAPE value below 10% indicates that this method is effective for blood stock planning at UDD PMI Langkat, helping to optimize blood inventory management and minimize the risk of shortages or surpluses.
