Abstract
Transportasi memegang peranan yang penting dalam segala aspek kehidupan, terutama dalam bidang ekonomi. Dengan meningkatnya kebutuhan sistem transportasi yang lebih cepat, efisien, nyaman dan ramah lingkungan, maka perlu adanya pengembangan transportasi. Kereta melayang magnetik atau magnetic levitation (maglev) train adalah salah satu kandidat terbaik yang memenuhi persyaratan tersebut. Maglev mengganti roda kereta api konvensional dengan elektromagnet dan melayang diatas rel. Teknologi ini menggunakan gaya dorong elektro-mekanikal tanpa adanya kontak. Dengan teknologi ini kerugian akibat gesekan antara benda kerja dengan landasannya dapat dihilangkan. Teknologi yang digunakan dalam kereta ini adalah Electromagnetic Suspension (EMS).
Penelitian dimulai dengan perancangan solenoida-elektromagnet. Peralatan
kendali, sensor dan elektromagnet dirakit menjadi sistem melayang magnetik satu unit. Sistem melayang magnetik yang diinginkan adalah sistem yang mampu menarik berat elektromagnet ditambah beban tambahan. Sistem melayang magnetik diuji dengan cara pengambilan data kuat medan magnet dan arus yang melewati elektromagnet. Selanjutnya sistem melayang magnetik yang telah ada digandakan menjadi empat. Sistem melayang magnetik digabung dengan struktur kereta dan rel. Penggabungan tersebut akan menghasilkan purwarupa kereta melayang magnetik.
Parameter elektromagnet yang dihasilkan memiliki panjang 30 mm, jumlah lilitan 800 dan diameter kawat 0,4 mm. Sistem dapat berjalan dengan menggunakan sensor inframerah-photodioda. Kendali Proportional-Derivative (PD controller) mampu menjaga sistem melayang magnetik berjalan stabil. Parameter PD controller gains adalah Kp sebesar 2,467 dan Kd sebesar 0,015. Sistem mampu menarik objek berbobot 85 gram. Objek melayang ±2 milimeter dari elektromagnet.

Transportation holds vital role in every life aspect, especially in economic. The public need a new-generation transportation system. The transportation system has rapidity, reliability, safety, convenience and environment-friendly. The magnetic levitation (maglev) train is one of the best candidates to fulfill those requirements. Maglev replace conventional train’s wheels with electromagnets. It makes train levitates on the guideway. This technology use electro-mechanical forced to propel without any contact. This technology allow null friction loss between vehicle and it supports. This train use the Electromagnetic Suspension (EMS) technology.
The research is started with electromagnet-solenoid design and the control system. An electromagnet, sensor and control system are assembled to create one unit of maglev system. Maglev system need to pull its weight and additional load. The maglev system is tested by logging its magnetic field and electromagnetic current. The existing maglev system copied into four units.
Maglev systems integrate into train structure and rail. The integration created
a prototype of magnetic levitated train.
Electromagnetic design parameters are 30 mm of solenoid length, 800 of
coils, 0,4 mm of solenoid wire diameter. The system use infrared-photodiode as sensors. Proportional-Derivative (PD) controller could keep the maglev system stable. PD controller gains are Kp=2,467 and Kd=0,015. The system could pull 85 grams object. The object levitate ±2 milimeters from electromagnet.
