Design of a micro-scale wind turbine with horizontal axis using airfoil NACA 4412

The high demand for electrical energy leads to the depletion of fossil fuel reserves. Therefore, alternative energy is required to overcome the scarcity of fossil fuels. Regardless of the fact that natural resources are renewable as alternative energy such as wind, water, ocean waves, and sunlight. Wind on the south coast of Malang, Indonesia provides good potential as alternative energy. The design in this paper is focused on designing a horizontal axis wind turbine with 4 blades with a length of 50 cm utilizing the NACA 4412 Airfoil profile. The wind turbine is designed utilizing a low-speed permanent magnet generator around 500-1000 rpm to produce a design power of 100-125 Watt and the maximum power of the generator of 270 Watt. The wind turbine that has been designed has a tower-shaped support that uses iron pipes and is pulled by 4 steel ropes that are plugged in each pointing to the 4 cardinal directions

Adversity Quotient Pembangkit Motivasi Siswa Dalam Belajar Matematika

Adversity quotiont (AQ) adalah kecerdasan mengatasi kesulitan. Siswa yang memiliki AQ tinggi disebut siswa climber. Siswa climber gigih, ulet, dan tabah dalam menghadapi kesulitan. Mereka selalu berusaha mencari jalan keluar penyelesaian jika menghadapi kesulitan. Mereka tidak pernah membiarkan ada sesuatu yang menghalangi cita-citanya. Potensi Adversity Quotient telah banyak dimanfaatkan untuk meningkatkan motivasi karyawan di dunia kerja, Perusahaan, perkantoran, dan atlit berbagai cabang olah raga. Semenetara itu, dalam dunia pendidikan, Adversity Quotient belum banyak dimanfaatkan. Dewasa ini masih banyak siswa yang mempunyai kesan negatif terhadap matematika, misalnya: matematika dianggap sebagai momok, matematika menakutkan, bahkan ada siswa yang fobia terhadap matematika. Mengingat kondisi ini, potensi Adversity Quotient nampak sangat berperan dalam memotivasi siswa belajar matematika. Siswa yang memiliki motivasi belajar matematika yang tinggi, sesulit apapun materi pelajarann matematika itu, niscaya mereka akan senang belajar. Meningkatkan AQ siswa juga akan sendirinya membangkitkan motivasi siswa belajar matematika. Meningkatkan AQ siswa dapat dilakukan dengan LEAD, dengan megedepankan komponen D, yaitu melakukan sesuatu yang dapat menyadarkan siswa akan pentingnya belajar matematika. Kata
