Abstract

The electroplating industry produces wastewater containing heavy metals. The high surface area of bacteria has the potency to reduce heavy metals content in wastewater since it has ability to absorb the metals. This study aims to find out the bacterial DNA profile after Cd bioremoval process using Bacillus cereus 9632 and Pseudomonas aeruginosa WT. Bacterial culture is applied in synthetic electroplating wastewater. Some Cd concentrations are used to perform Range Finding Test by bacterial culture. The study was conducted in a batch system for three days. The viability test was done by measuring the value of Optical Density and Total Plate Count, while bacterial DNA profile was analyzed by using electrophoresis. The cell viability of B.cereus ATCC 9632 and P.aeruginosa WT had the same pattern which is the higher concentration of Cd metals on cell bacteria surface, the lower cell bacteria viability. The DNA of the control bacteria has the difference between the size and number of bands.

Abstract

Pertumbuhan jumlah penduduk di Kota Balikpapan diproyeksikan mencapai 833.761 jiwa pada tahun 2032. Pada tahun 2014 angka kebutuhan hunian di Provinsi Kalimantan Timur mencapai 239.964 unit hunian. Penghuni rumah susun di Kota Balikpapan hanya sebesar 75% dari total 595 unit hunian. Adanya tumpang tindih kebijakan antara Peraturan Daerah Nomor 7 Tahun 2011 tentang Rumah Susun tidak relevan lagi dengan dokumen Rencana Tata Ruang Wilayah Kota Balikpapan. Penelitian ini bertujuan untuk menentukan faktor prioritas berdasarkan preferensi pemerintah menggunakan teknik analisis Analytical Hierarchy Process (AHP). Analisis AHP menghasilkan faktor dan variabel prioritas berdasarkan preferensi pemerintah yaitu faktor prasarana dengan variabel jaringan air bersih, faktor hukum dengan variabel kesesuaian penggunaan lahan dan faktor kepemilikan dengan variabel sistem sewa.
