Abstract

Tugas Akhir merupakan mata kuliah wajib bagi mahasiswa fakultas teknik Universitas Wahid Hasyim Semarang sebagai syarat wisuda. Proses pelaksanaan mata kuliah Tugas Akhir masih menggunakan sistem manual yaitu mahasiswa harus mendatangi koordinator Tugas Akhir untuk menyerahkan berkas-berkas syarat pelaksanaan Tugas Akhir sehingga membutuhkan waktu yang relatif lama dan tidak efisien, selain itu karena sistem ini masih bersifat “paper based” koordinator Tugas Akhir sangat kesulitan dalam mengorganisisir berkas-berkas Tugas Akhir yang dapat mengakibatkan berkas tersebut terselip, rusak bahkan hilang dan juga kesulitan dalam mengetahui serta memanajemen dosen pembimbing Tugas Akhir. Untuk memecahkan masalah tersebut peneliti membuat sebuah sistem informasi berbasis Website yang dapat diakses secara online, sistem ini dibangun menggunakan metode waterfall dengan framework PHP dan didukung dengan database MySQL untuk mengolah basis datanya. Hasil dari penelitian ini adalah sebuahsistem informasi Tugas Akhir berbasis web pada fakultas teknik Universitas Wahid Hasyim Semarang.

Abstract

This study aimed to determine effect of oxygen enrichment and magnetic field direction on the flame behavior kapok oil combustion. Experiment was carried out to obtain flame evolution, temperature and height. Kapok oil (600 ml) was put in the boiler, and heated to 300°C. A burner chamber is placed for the reaction between kapok oil vapor with air from compressor and oxygen. Two permanent magnets of neodymium nickel grade N52 with intensity 1.1 Tesla were placed on side of burner tip. Results showed the magnetic field produce more transparent, slimmer flames with highest temperature of 679°C, lowest flames height of 5 mm. Magnetic fields produce a Lorentz force that breaks the fuel chemical chain and creates magnetic pulses in the flames. Oxygen contained in air around the burner coupled with oxygen enrichment create excessive oxidizing gas to separate and release electrons. Excessive oxygen results in a higher flame temperature due to faster combustion reaction. The magnetic fields around flames induces flow air which magnetically cause heat transfer around the flame, resulted variable flame height. This combustion produces different flame evolution, temperature, and height. Keywords: Flames behavior, Flames colour, Kapok oil, Magnetic field, Premixed combustion.
