Penurunan Zat Organik dan Kekeruhan Menggunakan Teknologi Membran Ultrafiltrasi dengan Sistem Aliran Dead-End (Studi Kasus : Waduk Saguling, Padalarang)

A laboratory scale experiment to study the aplicability of ultrafiltration membrane technology to treat the water of Saguling Reservoir has been done. The main parameters in this study are flux, organic content, and turbidity. The membranes used are cellulose accetate based membrane, composed of 11, 13, 15 percent cellulose accetate respectively. Chemical analysis of Saguling Reservoir water shows that, color, organic content, and turbidity are the parameters exceeding the standard. In this study, treated water by using Poly Alummunium Chloride (PAC) as feeding solution was also been used. The results shows that CA-15, membrane has 15 % content of cellulose accetate, performed best. The permeability of the membrane was 5-12 l/m2.hr.bar, and rejects up to 90 % of organic content, 90-100% rejection of Total Suspended Solid and 90% turbidity

PROSEDUR PEMERIKSAAN CT-SCAN KEPALA DENGAN DIAGNOSA CEDERA KEPALA SEDANG DI INSTALASI RADIOLOGI RSUD KOTA SALATIGA

Pemeriksaan CT-Scan kepala menurut teori, menggunakan scan area dari basis cranii hingga vertex. Di Instalasi Radiologi RSUD Kota Salatiga, pemeriksaan CT-Scan kepala dengan diagnosa cedera kepala menggunakan scan area dari cervical 7 hingga vertex, untuk pasien diagnosa CKS dan CKB ditampilkan gambaran MPR cervical. Tujuan penelitian ini adalah mengetahui prosedur pemeriksaan CT-Scan kepala diagnosa cedera kepala sedang, alasan dibuat gambaran MPR cervical, dan informasi diagnostik gambaran cervical rekonstruksi CT-Scan. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Pengambilan data dilakukan pada bulan Maret 2020 dengan observasi langsung, wawancara mendalam, dan studi dokumentasi.Hasil penelitian menunjukkan, prosedur pemeriksaan CT-Scan kepala diagnosa cedera kepala sedang menggunakan scan area dari cervical 7 hingga vertex. Pasien diagnosa CKS dan CKB ditampilkan gambaran MPR cervical. Alasan dibuat gambaran MPR cervical adalah memperoleh gambaran cervical empat proyeksi. Informasi diagnostik dari hasil MPR adalah mendapatkan visualisasi struktur spesifik, menentukkan luas lesi, melokalisasi lesi dan fragmen tulang
