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.

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

Decision support system in development and Down-streaming of coconut-based agroindustry constitutes a meaningful approach for stakeholders in decision making process, in which it is semi-structural process in coconut agroindustry. This current work aimed to identify and analyze a method and approach in development of coconut agroindustry and its downstream, as well as to collaborate and criticize both stages. This work has reviewed 146 scientific articles from 5 main publication databases worldwide published between 2000 – 2018. The identification and classification techniques of this work included multicriteria decision making, financial feasibility study, qualitative and quantitative study, while the methods were generally grouped into decision support system, multicriteria decision making, multi objective decision making, smart system. Currently, methods in decision making system in the area of coconut agroindustry in both downstream and development stage mostly discussed in traditional perspective, without considering spatial intelligent decision support system which enables us to create decision faster. This work successfully built research framework as feed for further model development using smart decision making system covering development and downstream coconut agroindustry with integration of potential area mapping model, product development, and institutional aspect.

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

Three isolates name as Pseudomonas aeruginosa (PA), Pseudomonas pseudomallei (PP) and Enterobacter agglomerans (EA) are petroleum hydrocarbon degrader bacteria. They were grown in mineral medium and 10% diesel oil as carbon source. The diesel oil biodegradation by PAEA and PPEA are better than single or other mixed cultures. The diesel oil compounds are oxidized to intermediate product and detected as fatty acids ranged of nC18 to nC8, organic acids, and then it was mineralized. The mineralized products measured as methane, carbon dioxide, and carbon monoxide. This result showed that during hydrocarbon biodegradation of aliphatic compounds by those isolates through fatty acids formation, simple organic acids, and simple volatile organic carbon. The mineralized product of methane, carbon dioxide, and carbon monoxide were emitted to the environment. Keywords: Biodegradation, diesel oil, Pseudomonas, Enterobacter, minerallized

Abstract

Leachate is a waste water formed from the disposed garbage in landfill site. Leachate has a high content of ammonium that can contaminate water. Ammonium removal can be done by struvite precipitation. Struvite precipitation is a process of precipitation by chemical reactions assisted with precipitant chemicals containing Mg2+ and PO43- forming a precipitate of struvite crystals (MgNH4PO4.6H2O). This study aimed to determine the effect of molar ratio and pH on ammonium removal and other important pollutants from leachate. The leachate used for the experiments was taken from landfill Galuga, Bogor Regency that is used for disposal of municipal solid wastes from Bogor City and its surroundings. MgCl2.6H2O and Na2HPO4.2H2O were used as precipitants. The process was conducted in a jar test with stirring speed of 120 rpm for 15 minutes with sedimentation time of 45 minutes. Results showed that this process could reduce ammonium concentration as well as other important pollutant levels, such as COD, TSS, turbidity, and colour. The best ammonium removal efficiency was obtained at molar ratio of 1: 1.3: 1.2 and pH 9 with an ammonium removal of 80.51%. In this condition, removals of 46.67% COD, TSS 96.04%, turbidity 86.1%, and colour of 86.43% were achieved.Keywords: Ammonium, leachate, molar ratio, precipitation, struvite

Abstract

The growth of the milk industry in Indonesia is increasing every year. This is due to population growth, Indonesian income increasing, and their awareness of consuming milk benefit. Milk production in Indonesia comes from small and medium-term farmers, requiring Koperasi to improve the quality of dairy products in Indonesia. Koperasi Mitra Jaya Mandiri (MJM) consists of dozens of small local farm which all activities are still done manually. Activities of Koperasi MJM, farmers and milk transportation have an impact on the environment. The objective of this research is identify inputs, outputs and environmental impacts in the production of 1 kg of fresh milk (case study of Koperasi MJM). The methods used are life cycle assessment (LCA) with three impact categories: global warming (GWP), eutrophication potential (EP) and acidification potential (AP). The boundary of LCA study is "cradle to gate", which include: feed production, dairy farming activities, transportation of milk to Koperasi, cooling of milk in Koperasi and transportation of milk to factory. Based on LCA results, the environmental impact of GWP, EP and AP 1 kg of Koperasi MJM fresh milk equals 3.45 kg CO2 eq, 0.018 kg PO43- and 0.0208 kg SO2 eq. The stage of dairy farming activities has the highest environmental impact in these three categories. Environmental impact reduction can be done by processing feces of cow, or choosing feed additive that more environmentally friendly. Key words: Life Cycle Assessment, fresh milk, cradle to gate, environmental impact, diary farm
