Rancang Bangun Tempat Sampah Pintar dengan Sistem Monitoring Berbasis Cloud dan Internet of Things (IoT) Menggunakan Metode Rule-Based

Cleaning staff sometimes experience delays in emptying trash bins because inspections are conducted manually. This method is inefficient as it can lead to trash accumulation, causing odors and potential health hazards. Therefore, this study aims to improve the efficiency of waste management. The research method used in this study includes design and development, involving needs analysis, system design, system implementation, and system testing. In this study, a trash bin monitoring system was designed using the ESP32 microcontroller, the HC-SR04 sensor to detect bin capacity, and the MQ-135 sensor to detect ammonia gas content in the trash. The system can detect the bin's capacity, the last cleaning time, and the ammonia odor in the trash. The determination of trash collection actions is carried out using a rule-based method with 100% accuracy, and notifications are sent via Telegram

The Influence Of The Use Of E-Book And E-Learning Base In Students Achievement

One of way to increase the students achievement of mathematics departement Siliwangi Univercity of Tasikmalaya, net to development of learning model e-book and e-learning basic in analytic Geometry Learning. It is based on the result of students’study for analytical Geometric cis is not maximum. So, hopefielly if the result of analytical Geometric learning increase, the students’ achievement will increase too. This observation, e-book and e-learning basic in Geometric analytical, is to develop thr learning model, increase the students’ achievement of mathematic department and analysis students responses in using of this models. The conclusion is that the development of e-book and e-learning model in analytical geometric implementation can increase the students achievement and the responses of mathematics students of Siliwangi Univercity in Tasikmalaya is positive. Key words : electronical book and electronical learnin

Peningkatan Pedagogical Content Knowledge Guru Matematika Dan Praktiknya Dalam Pembelajaran Melalui Model Pelatihan Teqip

: The Improvement of the Pedagogical Content Knowledge of Mathematics Teachers and Their Teaching Practices Using TEQIP Model. This study was carried out to improve the pedagogical content knowledge of mathematics teachers and their teaching practices in mathematics class in reference to Teachers Quality Improvement Program (TEQIP) Model. TEQIP is an in-service training model with meaningfull learning and integrated lesson study. The study was conducted for four years (2010-2014) on 1000 matematics teachers sprawling in 14 provinces across Indonesia. TEQIP activities were focused on pedagogic and content knowledge improvement with five kinds of activities and teaching practice im­provement in mathematics classes. The results suggest (1) the improvement of matematics content knowl­edge (39.45 points) and problem solving competence (47.48 points); (2) the improvement of pedagogic knowledge—teaching and learning model (25 points), assesment (32.5 points), learning media (42.25 points), and mathematical error case study (27.5 points); and (3) the improvement of teaching and learning practices—motivating the students (1.45 points), using learning media (2.05 points), meaningfull learning (1.87 points), having learning interaction (1.65 points), and giving due responses to learning problems (1.23 points)

Positive operator valued measures covariant with respect to an irreducible representation

Given an irreducible representation of a group G, we show that all the covariant positive operator valued measures based on G/Z, where Z is a central subgroup, are described by trace class, trace one positive operators.Comment: 9 pages, Latex2
