Abstract

The cation flotation method was employed to enrich the A-modernite fraction by observing the change of the mixture density, pH, type and concentration of collector and concentration of HF as a function of the floated quantity of this A-morderite. X-ray diffraction analysis using Shimadzu XD-D1 was conducted to examine the specimens for several variations and settings. The d-spacing identifications were done by comparing the experimental data with the ICDD database and then quantitative analyses were performed. Before the treatment, the existence of A-mordenite in this natural product was confirmed, it has space group Fd3m with lattice parameters a = (24.46 ± 0.96) Å. The average weight concentration before the treatment was 41,02%. The remaining mineral was identified as epistilbite Ca3Si9Al3O24.8H2O, clinoptilolite [KNa2K2] Al2Si10O247H2O and B-mordernite [CaNa2K2]Al2Si10O24.7H2O. After the treatment, higher concentration of A-mordenite was obtained by setting a higher collector concentration, lower HF activator, and pH value to the value 5.0. The highest concentration of A-mordenite was achieved when the setting was 66.45%. The crystallographic structure remained the same since there were neither violent chemical reactions nor heating in all the processes.

Abstract

Tujuan sosialisasi penyuluhan ini adalah untuk membasmi bakteri penyebab penyakit hingga tuntas dan untuk mencegah terjadinya resistensi antibiotik yang berbahaya. Antibiotik menjadi salah satu jenis obat yang sering digunakan dan berakibat terjadinya resistensi. Masyarakat Kp. Cipeujeuh Desa Ciwangi kecamatan BL Limbangan kabupaten Garut masih sangat banyak masyarakatnya yang minim akan pengetahuan tentang penggunaan antibiotik,kami melakukan penyuluhan dalam sosialisasi di Kp. Cipeujeuh. Banyak masyarakat yang tidak tahu apa kegunaan dan cara menggunakannya antibiotik ini sehingga banyak masyarakat yang mudah sakitResintensi antibiotik meningkat karena pengetahuan yang tidak memadai serta penggunaan antibiotik yang tidak rasional. Pelaksanaan kegiatann ini KKN Mahasiswa. Dan setelah kami melakukan sosialisasi masyarakat baru sadar akan cara menggunakan antibiotk yang tapat dan benar
