Abstract

Research of bioremediation of petroleum waste by indigenous petrophilic bacteria with biopile techniques at Klamono Area in Papua has been done. Petroleum waste was derived from various sources, namely tank cleaning, oil spills, oil catcher, leaking pipes, and drilling wastes containing oil residue. Preparation of petroleum waste has been done by adding wood sawdust as a bulking agent as much as 10% (w/w), the ratio of C: N: P: K = 100:5:1; 0.1 and mixed cultures of indigenous petrophilic bacterial isolated from the sources of the waste that has been collected in a storage-pit that Pseudomonas sp. (PSP01), Pseudomonas sp. (PSP05), and Bacillus sp. (PSP03) with 1:1:1 ratio of 0.5% (v/w). During the bioremediation process was aerated at a rate of 1 liter/jam/m3. Monitoring process have been done every week by doing the sampling with multiple sampling method to determine the five stations and each station has determined three sampling points,namelythe surface, middle and bottom based on the depth, samples have been obtained pooled and analyzed. The results showed that a decline in Total Petroleum Hydrocarbon (TPH) of 91.04% for six weeks. Total bacterial populations during bioremediation processes ranging 103 to 108 CFU/gram of soil. In addition at the end of the observation showed that the toxic aromatic compounds benzene, toluene, ethylbenzene, and xylene (BTEX) showed concentrations under the Environmental Quality Standards. Thus, indigenous petrophilic bacteria effective as biological agents in the bioremediation of petroleum waste by biopile method.

Abstract

Latar Belakang: Demam Tifoid merupakan penyakit infeksi akut usus halus yang disebabkan oleh bakteri Salmonella typhi dan merupakan masalah utama kesehatan masyarakat Indonesia. Berdasarkan laporan World Health Organization (WHO) diperkirakan 11-20 juta orang di dunia terkena penyakit demam tifoid dan menyebabkan kematian sekitar 128.000 - 161.000 jiwa. Berdasarkan uraian di atas, maka penelitian ini dilakukan untuk melihat karakteristik penderita demam tifoid di rumah sakit Ibnu Sina kota makassar pada tahun 2016-2017. Metode: Penelitian ini bersifat deskriptif dengan metode total sampling menggunakan data sekunder dari rekam medik. Pada penelitian ini didapatkan jumlah penderita demam tifoid tahun 2016–2017 sebanyak 233 orang. Hasil: Kejadian demam tifoid tertinggi adalah tahun 2016 bulan April sebanyak 26 orang (14,8%) dengan kelompok usia terbanyak yaitu 21-30 sebanyak 80 orang (34,3%), jenis kelamin terbanyak perempuan sebanyak 124 orang (53,2%). Jenis pekerjaan penderita demam tifoid terbanyak yaitu kelompok mahasiswa sebanyak 62 orang (26,6%) dengan gejala subjektif demam sebanyak 233 orang (100%). Pada pemeriksaan lidah kotor positif sebanyak 80 orang (34,3%). Pemeriksaan penunjang diagnosis yaitu pemeriksaan darah rutin didapatkan yang mengalami anemia sebanyak 38 orang (12,5%). Kesimpulan: Gejala subjektif tertinggi yaitu demam dengan pemeriksaan fisis yaitu lidah kotor. Pemeriksaan penunjang diagnosis terbanyak adalah pemeriksaaan darah rutin dan pemeriksaan laboratorium yang sering dilakukan adalah tes widal.
