Abstract

The need for electrical energy has increased every year. On the other hand, the largest power plants in Indonesia still use non-renewable energy sources such as coal and petroleum, while these non-renewable energy sources will eventually run out. To anticipate running out of this energy, a renewable energy source is needed. This existence will not run out even though it is consumed every day. Renewable energy that can be used for conversion into electrical energy in coastal areas is wave power.  The waves that always crash on the shoreline can be used to drive turbines. The turbine rotates due to the crashing waves connected to a DC generator. It will convert mechanical energy into electrical energy. The electrical energy generated by the DC generator is used to charge the battery. The purpose of this research is the know-how to design a wave power generator and to determine the performance. The experimental method is used in this study. In the results, the generator works optimally during the day with the resulting voltage of 10.6 V to 10.7 V with rotation speed of 623 Rpm to With 710 Rpm.

Abstract

Fokus penelitian ini untuk mengetahui kearifan lokal Madura yang diterapkan pada pola asuh, implementasi pola asuh berbasis kearifan lokal Madura oleh wali murid di PAUD Darul Mukhlisin serta untuk mengetahui apakah pola asuh berbasis kearifan lokal Madura dapat meningkatkan sosial emosional anak usia dini di PAUD Darul Mukhlisin. Penelitian ini menggunakan metode penelitian kualitatif deskriptif dengan metode pengumpulan data observasi, wawancara, dan dokumentasi. Peneliti juga menggunakan teknik analisis data model Miles dan Huberman, yaitu pengumpulan data, reduksi data, penyajian data, dan penarikan kesimpulan. Sehingga dari penelitian ini menunjukkan hasil bahwa wali murid di PAUD Darul Mukhlisin memberikan pola asuh berbasis kearifan lokal Madura dengan budaya ter-ater. Penerapan yang dilakukan dengan mengenalkan sejak dini dan melibatkan langsung anak dalam budaya ter-ater. Pola asuh tersebut dapat dengan baik meningkatkan sosial emosional anak, membentuk karakter anak, percaya diri, berani, dan baik dalam bersosialisasi dengan orang lain.
