Production System Design bio-oil of Microalgae with POME as Raw Material For Media Cultivation

Palm Oil Mill Effluent (POME) produced by the Palm Oil Mill as a waste is now being used as a medium for cultivating microalgae for bio-oil raw materials. However, the bio-oil production process from POME raw materials is still limited to lab scale. Therefore, in this project, the analysis of bio-oil production system from microalgae for the development of existing production system. In this paper, the optimization model of bio-oil production from microalgae biomass is simulated into Digital Business Ecosystem (DBE) concept then analyzed to related stakeholders in system and interaction of each process or between fellow stakeholders. And the results are defined in the form of Information Communication and Technology (ICT). The method used for this DBE concept is Unified Modeling Language (UML) which is use case diagram and Business Process Model and Notations (BPMN) diagram. And to predict an increase in yield by using ARM (Association Rule Mining). The results of this study are shown in the use case diagram and BPMN consisting of five communities, namely raw materials community, cultivation community, harvesting community, extraction community and quality control (QC). The process of production and storage of the resulting data is illustrated in the BPMN diagram. In this paper the association rule is used to explore the relationship pattern between Cell Density attributes, Lipid Content and Light Intensity. The integration of association rule with a priori paradigm has succeeded in finding 34 rules with 11 valid rules top rank which have lift > 1 of relation between attribute

Utilization of Palm Oil Mill Effluent (POME) from the Residual Biogas Power Plant for Microalgae Production as Raw Material of Biodiesel

Palm Oil Mill Effluent (POME) from the residue of biogas power plants generated by the Palm Oil Mill as the waste is still a problem in the processing environment and the environmental impact. However, POME waste still contains nutrients which are essential to the growth of microalgae as a growing medium. Utilization of POME can improve the growth of microalgae Botryococcus braunii compared to conventional media. By doing this project, the cost used by the palm oil mill waste management can be reduced and even be able to provide profits for palm oil mill and also can reduce the negative impact on the environment. The study was conducted at the Microalgae Laboratory of SBRC - IPB in September-Oktober 2018. Botryococcus braunii was cultivated in 1,000 ml erlenmeyer compared to standard medium as the control solution of 0.1% POME from the residue biogas power plants. Observation of Botryococcus braunii growth curve has carried out in accordance. Studies were arranged in CRD, with three replication. The results showed that the rate of Botryococcus braunii growth in POME is higher than the control for 2.7x106 sel/ml. And lipid extraction using osmotic shock method with HCl and CH3COONa as osmotic agents in concentrations of 0.1; 0.3; 0.5 M, the highest yield of 0.108 g was obtained on the osmotic agent CH3COONa 0.3 M
