Opis:
The objectives of this research are to study the direct influence on the competitive advantage and pattern development of variables affecting the competitive advantage of the Thai oil palm industry. This research employs a quantitative research method. The population for the study consists of 150 oil palm industrial operators in Thailand. Questionnaires are used in the data collection and the data are analyzed by using SEM. The research results reveal that the Knowledge Management Process and Supply Chain Integration positively influence the competitive advantage in the quality, delivery, and cost. The competitive advantage receives a positive direct impact from the Knowledge Management Process and Supply Chain Integration. The variation of competitive advantage can be explained as 84%. The obtained results can be used for developing the industry to create economic growth and sustainable competitive advantage.

Opis:
In this work, response surface optimization strategy was employed to enhance the biodegradation process of fresh palm oil mill effluent (POME) by Aspergillus niger and Trichoderma virens. A central composite design (CCD) combined with response surface methodology (RSM) were employed to study the effects of three independent variables: inoculum size (%), agitation rate (rpm) and temperature (°C) on the biodegradation processes and production of biosolids enriched with fungal biomass protein. The results achieved using A. niger were compared to those obtained using T. virens. The optimal conditions for the biodegradation processes in terms of total suspended solids (TSS), turbidity, chemical oxygen demand (COD), specific resistance to filtration (SRF) and production of biosolids enriched with fungal biomass protein in fresh POME treated with A. niger and T. virens have been predicted by multiple response optimization and verified experimentally at 19% (v/v) inoculum size, 100 rpm, 30.2°C and 5% (v/v) inoculum size, 100 rpm, 33.3°C respectively. As disclosed by ANOVA and response surface plots, the effects of inoculum size and agitation rate on fresh POME treatment process by both fungal strains were significant.

Opis:
This paper discussed the treatment of Malaysian petroleum sludge by incorporating palm oil fuel ash (POFA) to replace Portland cement and quarry dust (QD) replaces sand in the solidification /stabilization (S/S) method. Preliminary studies, including chemical composition, heavy metal characterization, density test, compressive strength test, and toxicity characteristic leaching procedure (TCLP), were done to evaluate POFA and QD suitability in S/S matrices. The 10% replacement of POFA recorded a considerable density value ranging from 1500 kg/m3 to 1660 kg/m3. As for S/S matrices containing petroleum sludge, the results indicate the possibility to of encapsulating the sludge in the matrices up to 10%. The highest strength of S/S matrices with petroleum is from PS5% samples with 15.61 MPa at 28 days. The toxicity characteristic of heavy metals from the S/S matrices was below the permissible limit set by USEPA. This investigation could be an alternative solution for petroleum sludge, POFA, and QD disposal and has excellent potential for replacing other treatment approaches employed at the advanced treatment stage for petroleum refinery effluents.

Opis:
This project describes the design and development of a camera vision with color detection for the variable rate technology (VRT) automated sprayer. In this project, the smart sprayer system was already developed and mounted on the ATV. The automated sprayer system was developed by combination of the electromechanical system, PC parallel port relay board, the controller and visual basic programming software. This smart sprayer system is guided with the camera to detect the presence of weeds. Detection of weeds is based on the green color value from RGB value. The amount or percentage (%) of weeds detected determines the rate of spraying that is controlled by an electric motor and the relay board. In this project, the spray nozzles were modified to be fully open, fully closed and half open. The closing and opening of valves were controlled by the electromechanical system that receives the instruction from the camera vision. Experiments carried out shows that the nozzle is closed when the percentage of weeds detected is less than 2%. It is half open at 3% to 50% and fully open at more than 51%. The application rate of spraying can be determined from the result of the spraying operation.
