Abstract

Several H-zeolite and HZSM-5 catalysts was preparated and their characters have also been investigated. H-zeolit Catalyst was preparated from Natural Zeolite that obtained from Malang District and Gunung Kidul District. Diethyl ether was produced by Ethanol with concentration of 95%. This research use fixed bed reactor that 1 gram of catalyst as bed catalyst, atmospheric pressure and temperature 140oC as the operating condition. Ethanol vapor from vaporization tank was driven by 200 ml/min Nitrogen stream. The responds in this research is liquid product concentration; diethyl ether, ethanol, methanol and water concentration. The results showed that the largest ethanol conversion was produced by the use of 56.44% HZSM-5 and the largest yield of diethyl ether diethyl was produced by the use of alumina and H-zeolite catalyst. The larger ratio between natural zeolite with HCl solvent will produce the larger surface area of catalyst and ethanol conversion. The largest ethanol conversion was produced at reactan ratio 1:20. [Keywords:  catalyst; ethanol conversion; dehydration process; yield of diethyl ether; natural zeolite].

Abstract

Penelitian ini bertujuan untuk mengetahui sejauh mana implementasi PUG diterapkan di lingkungan Politeknik Negeri Pontianak. Penelitian ini merupakan evaluasi deskriptif dengan menggunakan model CIPP (Context, Input, Process, Product) Penelitian ini menggunakan metode deskriptif kualitatif dengan trianggulasi sumber sebagai validitas data. Data diperoleh melalui observasi dan wawancara di lingkungan Politeknik Negeri Pontianak. Hasil penelitian dapat dilihat dari empat aspek yaitu: (1) konteks dalam implementasi PUG di lingkungan perguruan tinggi sesuai dengan Instruksi Peraturan Pemerintah Nomor 84 Tahun 2008 (2) Input pelaksanaan implementasi PUG di perguruan tinggi telah memenuhi persyaratan dalam hal sumber daya manusia (dosen dan tenaga kependidikan) serta sarana dan prasarana. Sebagian besar sumber daya manusia memiliki pengetahuan yang memadai dalam pelaksanaan program PUG (3) Implementasi di lingkungan perguruan tinggi terhadap responsif gender telah berjalan sangat baik di dalam proses kegiatan pembelajaran maupun di luar pembelajaran (4) Produk yang dihasilkan dari program responsif gender adalah terciptanya suasana yang harmonis, serta sarana prasarana menjamin ketersediaan untuk semua gender.
