Abstract
Tanah adalah suatu unsur penting dalam penyedia unsur hara. Saat ini, banyak fenomena pencemaran tanah Total Petroleum Hydrocarbon (TPH) yang terjadi di Indonesia. Tanah tercemar minyak banyak diakibatkan oleh aktivitas kebocoran pipa, tumpahan dari bahan bakar suatu industri, dll. Kerosin merupakan salah satu cairan hidrokarbon yang berasal dari hasil fraksional distilasi minyak bumi. Bioremediasi adalah suatu metode yang penting dalam menurunkan konsentrasi pencemar organik secara jangka panjang. Adapun tujuan dari penelitian ini yaitu mengkaji kemampuan tanaman Vetiveria zizanioides untuk menurunkan tanah tercemar kerosin, dan menganalisis pengaruh penambahan bioaugmentasi dan biostimulasi terhadap penurunan tanah tercemar kerosin.
Penelitian dilakukan dalam skala laboratorium. Dalam uji pendahuluan, tanaman Vetiveria zizanioides dilakukan uji propagasi untuk menentukan umur optimum tunas, aklimatisasi sebagai tahap penyesuaian tunas dan Range Finding Test (RFT) sebagai uji pencemar konsentrasi maksimum. dengan variasi konsentrasi sebesar 0%,5%,25%, 50%, 75%, 100%. Dalam penelitian utama, tahap fitoremediasi dilakukan variasi penambahan bakteri eksogeneous Staphylococcus gallinarum 10% v/v, pupuk urea 46%N, dan pupuk superfosfat 36%P dalam masing-masing reaktor dengan rasio C : N : P = 100 : 50 : 1. Selain itu. Analisis yang digunakan dalam penelitian ini adalah metode gravimetri, dan Total Plate Count (TPC) dengan teknik pour plate, gram staining, uji SEM bakteri serta analisis pH, suhu, kelembapan, bulk density, .
Berdasarkan hasil uji Range Finding Test, tanaman Vetiveria zizanioides mampu bertahan pada konsentrasi pencemar 5%. Selain itu, persentase penyerapan terbesar akar tanaman Vetiver zizanioides dalam menyerap kerosin selama 28 hari penelitian pada reaktor B sebesar 2,32%. Dalam penelitian ini, penambahan bioaugmentasi dan biostimulan memberikan hasil degradasi terbesar sebesar 33,83% lebih besar daripada variasi tanpa gabungan bioaugmentasi dan biostimulasi.

Soil is an important element in providing nutrients. Currently, there are many Total Petroleum Hydrocarbon (TPH) soil pollution phenomena that occur in Indonesia. Oil-polluted soil is often caused by pipe leaks, spills from industrial fuels, etc. Kerosene is a hydrocarbon liquid that comes from the fractional distillation of petroleum. Bioremediation is an important method in reducing the concentration of organic pollutants in the long term. The purpose of this study was to examine the ability of Vetiveria zizanioides plants to reduce kerosene-contaminated soil, and to analyze the effect of adding bioaugmentation and biostimulation on reducing kerosene-contaminated soil.
The study was conducted on a laboratory scale. In the preliminary test, Vetiveria zizanioides plants were subjected to propagation tests to determine the optimum age of shoots, acclimatization as a stage of shoot adjustment and Range Finding Test (RFT) as a test of maximum concentration pollutants. with concentration variations of 0%, 5%, 25%, 50%, 75%, 100%. In the main study, the phytoremediation stage was carried out by varying the addition of exogenous bacteria Staphylococcus gallinarum 10% v/v, urea fertilizer 46% N, and superphosphate fertilizer 36% P in each reactor with a ratio of C: N: P = 100: 50: 1. In addition. The analysis used in this study was the gravimetric method, and Total Plate Count (TPC) with pour plate techniques, gram staining, SEM bacterial tests and analysis of pH, temperature, humidity, bulk density.
Based on the results of the Range Finding Test, Vetiveria zizanioides plants were able to survive at a pollutant concentration of 5%. In addition, the largest percentage of absorption of Vetiver zizanioides plant roots in absorbing kerosene during 28 days of research in reactor B was 2.32%. In this study, the addition of bioaugmentation and biostimulants gave the largest degradation results of 33.83% greater than the variation without a combination of bioaugmentation and biostimulation.
