Abstract

The research on adaptation selection for utilization in phytoremediation of soil contaminated by crude oil using four type plants, such as Helianthus annuus, Paspalum conjugatum, Sorghum bicolor, and Tagetes erecta were conducted. The adaptability of four types of plants on crude oil contaminated soil at total petroleum hydrocarbon (TPH) level at 0, 3, and 6% were observed and evaluated to their morphological and anatomical responses. Parameters observed were vegetative growth of plants including growth precentage, plant height, number of leaves, root length, root dry weight, shoot dry weight, root/shoot ratio, total dry weight, and stomatal density for 9 weeks cultivation in screen house. The results show that increasing in TPH level caused in significant reductions on morphological of four plants, such as percentage of plant growth, plant height, number of leaves, root length, root dry weight, shoot dry weight, and total dry weight. In contrast, the increasing in TPH level caused to increasing in root/shoot ratio. The four types of plants studied were effective to be used as plants for phytoremediation of petroleum contaminated soil. The plants of P. conjugatum and S. bicolor are recommended as phytoremediators for further studies.

Abstract

Using bioaugmentation and biostimulation approach for contaminated soil bioremediation were investigated and implemented on field scale. We combine those approaches by culturing massively the petrophilic indigenous microorganisms from chronically contaminated soil enriched by mixed manure. Through these methods, bioremediation performance revealed promising results in removing the petroleum hydrocarbons comparatively using metabolite by product such as biosurfactant, specific enzymes and other extra-cellular product which are considered as a difficult task and will impact on cost increase.

Abstract

The actors in the palm oil supply chain industry are the farmers, traders, crude palm oil (CPO) factories, frying-oil factories (refineries), distributors and the consumers. The farmers sell fresh fruit bunches (FFB) to the CPO factories through traders. FFB is converted into CPO which is later sold to the refineries. Refineries convert CPO into frying oil which is sold to the consumers through the distributors. There are risks due to product quality consistency, price fluctuation and supply chain continuity. This study has two objectives: (1) to develop a model to identify, evaluate and rank the risks, (2) to develop a model to identify and rank the strategies in improving their added value. Data for this study was obtained through direct interviews and questionnaires. The respondents were selected experts and industry players. The data were processed using Fuzzy Analytic Hierarchy Process (FAHP) models. The first FAHP model showed that the two most important risks were the supply chain continuity and product quality. The second FAHP model showed that the recommended strategies to improve the added values of the actors were the improvement of the infrastructure/cluster development, followed by the usage of superior seeds and cultivation techniques.

Abstract

AbstractThe use of PET packaging in drinking products has increased and shifted glass packaging,so it is necessary to study the life-cycle of PET packaging. This research aims to evaluate lifecycle of PET bottles on tea beverage products. This life-cycle assessment includes productionprocess, inventory, environmental impact, and cost analysis. The life cycle of PET bottle inIndonesia is not complete. The relationship between PET bottle manufacturers, drinkingmanufacturers, and recycling waste, are unidirectional. The recycled waste-PET used forother products. Based on the analysis of inventory, PET bottles 600ml is nedeed 28g resin/bottles and energy. The PET packaging production still produced a high defective product.Environmental impact assessment of PET bottle production indicates that the ambient airquality, noise and waste water are still good. The impact of PET bottle plant produce aglobal warming potential, reduce ozone layer and acid rain. The cost analysis describethat selling price of PET bottles is half the price of a glass bottle, while the price of waste-PET flake is three times higher than cullet. Although PET packaging is considered morepractical, cheap and saving, but the recycling of PET packaging has not been widelyutilized.

Abstract

Malodorous gases emitted from natural rubber industries. At crumb rubber plant, leum storage emits high concentration of  ammonia that strength odor and dangerous to healthy workers. This research occurred to remove ammonia from leum storage using biofilter coloum 23L packed with mixed of top-soil, peat-rubber leaves and sludge. The result shows that this biofilters can remove ammonia  from inlet concentration at 4 - 20 ppm to  outlet concentration less than 4,7 ppm (average of 1,1ppm below regulation limit of 2 ppm). The biofilter packed with top soil performs  to ammonia removal efficiency average of 89% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and rubber leaves performs  to ammonia removal efficiency average of 85% and ammonia-removal capacity at 0,60 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge performs  to ammonia removal efficiency of 99% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge indicated the most stable on ammonia removal capacity and the lowest oulet ammonia at an average of 0.1 ppm.

Abstract

Phytoremediation is one of the most effective and environmental-friendly methods in retrieving oil-contaminated soil. The decline of Total Petroleum Hydrocarbon (TPH) oil in the phytoremediation process will be accelerated by Oil Spill Dispersant (OSD) as a surfactant and the use of Ricinus communis L. plant. Commercial OSD products used in the remediation process are S200 OSD which contains LAS surfactant, which is a US EPA recommendation and is known to be less environmental-friendly, so SBRC-IPB develops OSD containing palm oil surfactants and is environmental-friendly. The purpose of this study was to determine the performance of OSD and R. communis to reduce TPH. This study used a completely randomized design with two factors, namely OSD and plant use. The results of this study indicated that OSD from SBRC-IPB improved plant growth, increased dry plant biomass, accelerated the decrease in TPH and increased the bacterial population compared to the S200 OSD and control. The combination of OSD from SBRC and R. communis was able to degrade TPH better than S200 OSD, with and without R. communis, with TPH concentrations of 30,000 ppm (3%) to 2,333 ppm (0.2%) for 20 weeks. This showed that the use of OSD was able to provide a positive response in the phytoremediation process of land contaminated with petroleum

Abstract

The heavy oil waste (HOW) containing polyaromatic hydrocarbon (PAHs) is a persistent organic pollutants (POPs) that difficult to degrade. The new PAH degrading consortium was investigated from HOW contaminated soil in North Sumatera of Indonesia. The isolation, selection and identification of polyaromatic hydrocarbon degrading bacteria from soil contaminated by HOW was conducted to solve a bioremediation process. The isolation microbes from soil contaminated by HOW was performed using a minimum ONR7a media and followed on marine agar media for purification purposes. From the performed isolation results, 11 isolates were able to degrade PAHs compounds, such as phenanthrene, dibenzothiophene, or fluorene compounds. They grew at pH range of 4.8-8.2 and performed on emulsification activity in paraffin from 0.150-0.662. Three of them showed the best performance on HOW biodegradation capability and then successfully selected and identified as Salipiger sp., Bacillus altitudinis, and Ochrobactrum anthropi. using 16S rDNA. The HOW biodegradation as TPH-degradation were 38.66%, 59.60%, and 47.16%, respectively. Those isolated bacteria could potentially be as bioremediation agents to develop on bioremediation process for soils contaminated by HOW.
