"Penggunaan kompor induksi di Indonesia saat ini masih sedikit dikarenakan kurangnya pemahaman masyarakat terhadap pengetahuan mengenai kompor induksi dan cara penggunaannya. PT. Perusahaan Listrik Negara (PLN) baru - baru ini mengadakan program konversi satu juta kompor elpiji ke kompor induksi guna meningkatkan penggunaan kompor induksi dikalangan masyarakat Indonesia. Kompor induksi menggunakan prinsip kerja dari pemanasan induksi dimana arus dengan frekuensi tinggi mengalir melalui kumparan konduktor, arus dengan frekuensi tinggi kemudian menghasilkan medan magnet disekitar kumparan. Medan magnet yang dihasilkan tersebut akan menimbulkan skin effect pada panci yang berada di atasnya. Dengan adanya skin effect maka membuat arus eddy yang timbul karena induksi mengalir pada permukaan konduktor dan melakukan pemanasan terhadap panci. Hasil dari pengujian ini adalah setting daya yang dilakukan akan berpengaruh terhadap perubahan efisiensi, energi, dan waktu pada kompor induksi. Semakin besar setting daya yang digunakan efisiensi yang dihasilkan semakin tinggi, energi yang dibutuhkan semakin kecil, dan waktu yang diperlukan semakin cepat. Disamping itu, brand pada kompor induksi berpengaruh juga terhadap performansi dari kompor induksi.

The use of induction cookers in Indonesia is still slightly due to a lack of public understanding of knowledge regarding the induction cooker and how to use them. PT. Perusahaan Listrik Negara (PLN) recently held a program to convert one million LPG stoves to induction cookers to increase the use of induction cooker among the people of Indonesia. The induction cooker uses the working principle of induction heating where a high-frequency current flows through the coil conductor, a high-frequency current then produces a magnetic field around the coil. The resulting magnetic field will cause the skin effect on the pan above it. With the skin effect, it creates eddy currents that arise due to induction flowing on the surface of the conductor and heating the pan. The results of this test is conducted power setting will affect the efficiency change, energy, and time on induction cooker. The greater the power settings used the resulting higher efficiency, the less energy is required, and the time required is getting faster. Besides, the induction cooker brand also affects the performance of the induction cooker"

"Kualitas perpindahan gigi sangatlah penting untuk meningkatkan usia pakai sistem transmisi tersebut dengan cara mengurangi wear-and-tear pada komponen- komponen transmisi. Lebih lanjut, kemudahan pengoperasian yang dicapai dengan pengotomatisan tahapan perpindahan roda gigi sangat penting pada situasi yang sulit, sebagai contoh adalah perpindahan roda gigi kendaraan alat berat pada jalanan menanjak. Pada sistem transmisi manual, perpindahan roda gigi dilakukan dengan cara melepaskan kopling, menyambungkan roda gigi netral, perpindahan ke roda gigi yang baru, dan menyambungkan kopling kembali. Dengan menggunakan kontrol mesin terintegrasi, yang pada kendaraan listrik umumnya berupa motor induksi, sistem transmisi manual dapat diotomatiskan dan meniadakan kopling serta synchronizer, dinamakan sistem clutchless Automated Manual Transmission (AMT). Dengan mengestimasi nilai torsi pada sistem transmisi lalu mengendalikannya ke nol, fungsi kopling untuk memutuskan aliran daya dapat digantikan. Objektif tersebut dapat dicapai dengan kontrol vektor. Lebih lanjut, sistem transmisi manual yang diotomatiskan memiliki efisiensi yang lebih tinggi serta harga yang relatif lebih murah dibandingkan sistem transmisi otomatis lainnya.

The quality of gearshift is very important to increase the lifetime of transmission system by reducing wear-and-tear on the transmission components. Furthermore, the ease of operation achieved by automating the gear shifting stages is very important in difficult situations, for example the gear shifting of heavy equipment vehicles on uphill roads. In a manual transmission system, gearshift is performed by disengaging the clutch, connecting to a neutral gear, shifting to a new gear, and reconnecting the clutch. By using an integrated engine control, which in an electric vehicle is generally an induction motor, a manual transmission system can be automated and negate the clutch and synchronizer, named clutchless automated manual transmission system. By estimating the torque value in the transmission system and then controlling it to zero, the function of the clutch to disconnect the power flow can be replaced. This objective can be achieved using vector control. Furthermore, automated manual transmission systems have higher efficiency and relatively lower prices compared to other automatic transmission systems."

"This book is a quick reference source for induction heaters. It ties-in the metallurgy, theory, and practice of induction heat treating from a hands-on explanation of what floor people need to know. It includes practical tables and process analysis of induction heating, and was written to provide a combination of technical and practical information. For example, the book contains a method of analysis for various types of production processes on the same part; shows the recommended microstructure needed for induction hardening for various materials ranging from carbon to powdered metal steels; and discusses various nonconforming conditions in induction hardened parts and how to remedy these conditions. In the Second Edition, new material has been added including updated information on quenching methods, applications, inspection for quality control, and updated material on power supplies. "
