DEVELOPMENT OF FIGURE TOOL BASED ON FLOWMETER SENSOR TO APPLY THE EQUATION OF CONTINUITY IN DYNAMIC FLUID MATERIALS

Penelitian ini bertujuan untuk mendeskripsikan validitas alat peraga berbasis sensor flowmeter untuk menerapkan persamaan kontinuitas pada materi fluida dinamis dan untuk mendeskripsikan kesesuaian alat peraga berbasis sensor flowmeter untuk menerapkan persamaan kontinuitas pada materi fluida dinamis terhadap teori persamaan kontinuitas. Jenis penelitian yang digunakan adalah penelitian pengembangan dengan menggunakan model ADDIE (analysis, design, develop, implementation, evaluation). Validitas alat peraga berbasis sensor flowmeter dinilai berdasarkan hasil yang dilakukan oleh validator dan taraf ketelitian hasil percobaan menggunakan alat peraga. Kesesuaian alat peraga berbasis sensor flowmeter terhadap teori dianalisis menggunakan perhitungan akurasi. Berdasarkan data yang diperoleh, tingkat validitas alat peraga berbasis sensor flowmeter termasuk dalam kategori sangat baik dikarenakan hasil validasi dan taraf ketelitian alat peraga memiliki persentase ≥ 61%. Hasil validasi alat peraga menunjukkan persentase sebesar 92.7% dan data hasil percobaan menggunakan alat peraga berbasis sensor flowmeter memperoleh taraf ketelitian rata-rata pada sensor flowmeter pertama sebesar 95.76% dan pada sensor flowmeter kedua sebesar 95.13%. Sedangkan kesesuaian alat peraga terhadap teori persamaan kontinuitas didapatkan sebesar 97.3% dan tergolong dalam kategori sangat baik.

This study aims to describe the validity of flowmeter sensor-based visual aids to apply continuity equations to dynamic fluid material and to describe the suitability of flowmeter sensor-based visual aids to apply continuity equations to dynamic fluid material to the theory of continuity equations. This type of research is a research development using the ADDIE model (analysis, design, develop, implementation, evaluation). The validity of the flowmeter sensor-based teaching aids is assessed based on the results made by the validator and the accuracy of the experimental results using the teaching aids. The suitability of the flowmeter sensor-based props to the theory was analyzed using accuracy calculations. Based on the data obtained, the level of validity of props based on flowmeter sensors is included in the very good category because the results of validation and the level of accuracy of the props have a percentage of ≥ 61%. The results of the validation of the teaching aids showed a percentage of 92.7% and the experimental data using a flowmeter sensor-based teaching aid obtained an average accuracy level on the first flowmeter sensor of 95.76% and on the second flowmeter sensor of 95.13%. While the suitability of teaching aids to the theory of continuity equation is 97.3% and is classified in the very good category.
