Abstract

PAUD (Play Groups) Tunas Bangsa and PAUD Jati Asih are institutions that position parents as partners in the preparation and personal development from an early age, providing guidance to play groups and kindergartens in the Ngaliyan area of Semarang. Two institutions of Early Childhood Education that will become partners in the Community Partnership Program (PKM). Dra. Tri Edi Mhanani as the principal of Tunas Bangsa PAUD school and Ibu Sri Lestari Raahayu P., A.Md as the principal of Jati Asih PAUD school have the same topic, namely not having education related to environmental goals.  Educational props of the ladder snake game (EGUT) can help improve children's cognitive and psychomotor abilities. Children will learn to analyze colors, recognize letters, socialize, jump, throw, all of which are positive things in children's development. The material and features provided can help children to love the environment.

Abstract

Karakteristik torsi–kecepatan motor induksi memegang peranan penting dalam perancangan, pemilihan, serta strategi pengendalian motor listrik di berbagai aplikasi. Penelitian ini menyajikan pengujian eksperimental pada motor induksi dengan lima kondisi pembebanan, yaitu tanpa beban, 30 kg, 45 kg, 55 kg, dan 70 kg. Parameter tegangan, arus, kecepatan putar (RPM), dan daya dicatat menggunakan instrumen terkalibrasi, kemudian dihitung ulang nilai torsinya berdasarkan persamaan standar yang menghubungkan daya mekanik dengan kecepatan poros. Hasil analisis menunjukkan bahwa torsi rata-rata meningkat secara bertahap dari 0.339 Nm pada kondisi tanpa beban hingga 0.470 Nm pada beban 70 kg, seiring dengan penurunan kecepatan akibat slip yang lebih besar. Pola kurva torsi–kecepatan yang dihasilkan konsisten dengan bentuk teoritis menurut persamaan Kloss dan ekuivalen Thevenin. Studi ini menekankan bahwa meskipun tren hasil pengukuran sesuai teori, pendekatan perhitungan sederhana berbasis perkalian tegangan dan arus masih memiliki keterbatasan. Oleh sebab itu, penggunaan metode pengukuran torsi dengan dinamometer direkomendasikan untuk memperoleh akurasi yang lebih tinggi.
