Abstract

Kebutuhan akan data aktual terkait unjuk kerja mesin menjadi sangat penting dalam dunia penelitian. Data-data yang presisi mutlak diperlukan sebagai dasar dalam melakukan suatu pengembangan teknologi sebagai pembanding antara kondisi sebelum dan sesudah dilakukannya pengembangan. Penelitian ini adalah rancang bangun perangkat perekam data konsumsi bahan bakar dengan target ketelitian mencapai 10ml/menit dan Rasio Udara-Bahan Bakar (AFR) Digital untuk analisa unjuk kerja mesin pembakaran dalam. Konsumsi bahan bakar dihitung dengan pengukuran volume bahan bakar secara real-time sepanjang mesin digunakan dengan memanfaatkan sensor load cell sebagai pemberi informasi ke digital data logger dengan hasil tingkat ketelitian mencapai 3,4ml/menit. AFR diukur dengan menggunakan sensor oksigen yang diletakkan pada saluran gas buang mesin dengan hasil range pembacaan 10 s.d 20 AFR.

Abstract

The core shell structure of TiO2@SiO2@ferrite(Ni-Cu-Zn) as composite nanoparticles for magnetic photocatalyst were successfully prepared in this study. These particles were synthesized continually by the sol-gel method and they are tested for their performance using MB dye solution. The magnetic core particles used in the synthesis were (Ni-Cu-Zn) ferrite with size of 20-60 nm, while SiO2 and TiO2 layers were formed using tetraethoxysilane and tetrabutly titanate. Some characterizations and testinghavecarried out to investigate the crystal structure, magnetic properties, surface conditions and performance of these particles. The results show that the anatase crystal structure of TiO2 was obtained on the outer shell of the particle, while the magnetization value and surface area were achieved at 4.74 emu/g and 126,831 m2/g, respectively. The nanoparticles of composite size were obtained about 10 to 40 nm with the shell thickness up to 4 nm. The performance results of photodegradation was quite good for reducing MB dye up to 63.37%.
