Abstract
INDONESIA:
Vanadium (V) merupakan salah satu pencemar yang bersifat racun bagi makhluk hidup maupun lingkungan sekitar. Berdasarkan hasil uji pendahuluan yang dilakukan, limbah cair tambang minyak Desa Wonocolo mengandung vanadium (V) hingga 16,58 ppm ini berarti lebih tinggi dari standar vanadium dari EQS (environmental quality standard) yaitu 0,02-0,06 ppm. Bakteri yang hidup dalam lokasi tercemar vanadium (V) memiliki kemampuan resisten terhadap vanadium (V) dari limbah cair tambang minyak Desa Wonocolo serta dapat berpotensi sebagai agen bioakumulator pencemaran vanadium (V).
Jenis penelitian ini adalah deskriptif kualitatif dan eksperimental. Sampel yang digunakan berasal dari limbah cair tambang minyak bumi Desa Wonocolo yang akan dibuang ke lingkungan. Isolasi bakteri resisten logam vanadium (V) menggunakan media HMC (Halomonas complex) dengan penambahan logam vanadium 0 mM, 5 mM dan 10 mM. Variasi konsentrasi uji resistensi menggunakan kertas cakram yaitu 5 mM, 10 mM, 15 mM dan 20 mM. Identifikasi bakteri dilakukan secara makroskopik, mikroskopik dan uji biokimia menggunakan kit Microbact, sementara uji bioakumulasi menggunakan konsentrasi 0 µM, 200 µM dan 500 µM. Analisis bioakumulasi vanadium (V) menggunakan Spektrofotometri Serapan Atom (SSA). Data identifikasi isolat bakteri disajikan secara deskriptif, serta ada tidaknya pengaruh konsentrasi vanadium (V) dilakukan uji statistika One Way Anova dan dilanjutkan uji Duncan.
Penelitian ini menunjukkan bahwa terdapat 15 isolat bakteri resisten terhadap vanadium (V) dengan konsentrasi hingga 10 mM. satu isolat S2-4 mempunyai mempunyai rata-rata zona bening terkecil (uji resistensi difusi kertas cakram) dibandingkan dengan isolat yang lain (0,3 mm). Berdasarkan uji idenfikasi secara biokimia isolat S2-4 memiliki kemiripan dengan spesies Bacillus mycoides sebesar 78%. Bakteri S2-4 memiliki kemampuan mengakumulasi vanadium (V) sebesar 56,06% dalam perlakuan 200 µM dan 54,7% dalam perlakuan 500 µM.
ENGLISH:
Vanadium (V) is one of the pollutants that are toxic to living things and the environment. Based on preliminary test results, Wonocolo wastewater was containing vanadium (V) up to 16.58 ppm is higher than the vanadium standard of EQS (environmental quality standard) of 0.02-0.06 ppm. Bacteria living in vanadium-contaminated (V) locations can have vanadium (V) resistance capability from the Wonocolo oil wastewater and potentially as a bioaccumulator agent of vanadium (V) pollution.
This type of research is descriptive qualitative and experimental. The sample used came from the liquid waste of petroleum from Wonocolo Village which will be disposed of into the environment. Isolation of vanadium (V) metal resistant bacteria using HMC (Halomonas complex) media with the addition of 0 mM, 5 mM and 10 mM vanadium metals. Variations in concentration of resistance tests using paper discs are 5 mM, 10 mM, 15 mM and 20 mM. Bacterial identification was carried out macroscopically, microscopically and biochemically using a Microbact kit, while bioaccumulation tests used concentrations of 0 µM, 200 µM and 500 µM. Bioaccumulation of vanadium (V) analysis using Atomic Absorption Spectrophotometry (AAS). Identification data of bacterial isolates were presented descriptively, and the presence or absence of the effect of vanadium concentration (V) was carried out by One Way Anova statistical test and continued by Duncan test.
This study showed that there were 15 bacterial isolates resistant to vanadium (V) with concentrations of up to 10 mM. one isolate was S2-4 had the smallest clear zone average (disc paper diffusion resistance test) compared to other isolates (0.3 mm). Based on the biochemistry idenfication test S2-4 isolates have similarities with the Bacillus mycoides species of 78%. S2-4 bacteria have the ability to accumulate vanadium (V) by 56.06% in the treatment of 200 µM and 54.7% in the treatment of 500 µM.
