Abstract

There is air pollution who made by vehicle everyday can reduce healthy air quality if vailable trees is not enough to absorb pollution air gasses. This research to form pollution rate and air cleaning rate or carbon sinks into differential equation system and explain solution of mathematics model into minimal amount of trees who must be added to minimize pollution rate five years later. This research is observation and immediately going to research place calculate amount of tree and vehicle.

Abstract

Penelitian ini membahas tentang klasifikasi penderita anemia pada remaja putri dengan berbagai faktor yang mempengaruhinya. Penelitian ini bertujuan untuk mengetahui model klasifikasi penyakit anemia. Penelitian ini merupakan penelitian terapan dimana menerapkan teknik data mining yaitu metode regresi logistic untuk mengklasifikasi faktor-faktor penyebab anemia pada remaja wanita. Atribut yang digunakan yaitu faktor-faktor yang mempengaruhi anemia diantaranya ferritin serum, STfR, dan riwayat penyakit kronis. Hasil penelitian menunjukkan bahwa terdapat dua variabel yang berpengaruh secara signifikan dalam mengklasifikasi anemia yaitu ferritin serum, dan STfR dengan tingkat akurasi sebesar 79,23%, presisi sebesar 80,18%, dan recall sebesar 96,39%, yang berarti bahwa model cukup baik dalam mengklasifikasikan remaja putri yang terdiagnosis anemia dan tidak anemia.

Abstract

Mathematics learning on solid geometry is often considered difficult due to the limited media used, therefore more interactive media are needed. This study aimed to develop an interactive learning media assisted by Edpuzzle that is valid, practical, and effective. The type of research is Research and Development (R&D) using the 4D model (Define, Design, Develop, Disseminate). The research instruments included validation sheets, teacher and student response questionnaires, student activity observation sheets, learning implementation sheets, and learning achievement tests. The subjects were 23 seventh grade students of MTs Sultan Hasanuddin. The results showed that the developed media had a validity level of 95% (very valid). Practicality was indicated by teacher responses of 85% (very good) and the implementation of learning in the 'implemented' category. Effectiveness was shown by student activities of 90% (very active), student responses of 87.36% (very good), and 86.96% of students achieving the minimum mastery criteria with an N-Gain of 0.54 (moderate improvement). Therefore, the interactive learning media assisted by Edpuzzle was declared valid, practical, and effective to be used in mathematics learning on solid geometry.
