Abstract

Multilayer porous composite have been produced through the heating process at temperature T=700oC for 2.5 h. Single layered porous composite was made with a varied mass percentage of from PEG polymer  1% to 10%. Double-layered porous composite were made by the arrangement of porosity (4:3)%, (4:2)% and (3:2)%, while the three-layers porous composite have an arrangement (4:3:2)%. Performance of multilayer porous composite for water filtration with pollutants of methylene blue 100 ppm was estimated from the absorbance spectrum. Rejection of methylene blue pollutants from single layered porous composite increases when the fraction of PEG polymer tend to be smaller in the matrix. Meanwhile, the double layered porous composite has a degradation of methylene blue pollutants are better than one layer. Triple layered porous composite have good performance for the water filtration where all the pollutants of methylene blue be able to be filtered.   Komposit pori berlapis telah dihasilkan dengan proses pemanasan pada temperatur T=700oC selama 2.5 jam. Komposit pori satu lapis dibuat dengan variasi persen massa polimer PEG 1% hingga 10%. Komposit pori dua lapis dibuat dengan susunan porositas (4:3)%, (4:2)% dan (3:2)%, sedangkan komposit pori tiga lapis memiliki susunan porositas (4:3:2)%. Kinerja komposit pori berlapis untuk filter air dengan polutan methylene blue 100 ppm diestimasi dari spektrum absorbansi. Rejeksi polutan methylene blue dari komposit pori satu lapis meningkat saat fraksi polimer PEG cenderung lebih kecil dalam matrik komposit. Sedangkan, komposit pori dua lapis memiliki kemampuan untuk degradasi polutan methylene blue yang lebih baik dari satu lapis. Komposit pori tiga lapis memiliki kinerja yang baik untuk filter air dimana seluruh polutan methylene blue mampu disaring.

Abstract

Pengendalian kelajuan kendaraan menggunakan FLC pada cruise control telah dilakukan dengan menginjeksi sistem fuzzy pada sistem gerak kendaraan. Sistem fuzzy terdiri dari dua himpunan masukan berupa error kelajuan dan laju error kelajuan sistem. Penambahan Fuzzy Logic Controller pada sistem gerak kendaraan berpengaruh terhadap respon sistem untuk mencapai kecepatan yang diinginkan. Dengan penambahan FLC respon kecepatan dalam mencapai kecepatan yang diinginkan semakin cepat sehingga sesuai untuk diterapkan pada cruise control.Control vehicle speed using the cruise control FLC has been done by injecting a fuzzy system on the vehicle motion system. The system consists of two sets fuzzy input is the speed error and the error rate of the speed of the system. The addition of Fuzzy Logic Controller in the vehicle motion system affect the response of the system to achieve the desired speed. With the addition of FLC response speed in reaching the desired speed more quickly so appropriate to be applied to the cruise control.
