Engineering technological especially on automation and mechanization in agricultural and plantation industry is still new and still under research and development. The application of computer, mechatronics and machines for agricultural production has been one of the outstanding developments in Malaysian agriculture. This paper describes on the recent research at Malaysian public university on the uses of computer and electronics towards machines for the agricultural operations. It has been generally agreed that industrial robotics do not provide sufficient information related to the bioproduction field, although some fundamental theories and technologies were applicable to the bioproduction machine. Agricultural products are diversified and complicated, the environment around the objects changes from time to time, and the machine mechanism should adapt to physical properties and cultivation methods of the biological objects. These are some of the considerations that agricultural mechanization needs to address. Current trend in agriculture is integration with biotechnology application, the demand of which may increase in conjunction with the land capabilities by variety humanity activities. Although adoption of one agriculture activity per house area is a viable strategy in the framework of food security, as in a general, an agricultural production is labour intensive. The agricultural landscape has seen an increase in adoption of modern technologies, be it in small scales, including those in the agro-based manufacturing sector. This, to some extent, has increased the productivity and at the same time decreased the labour dependency. In conclusion, studies on electronic and computer-assisted devices leading to automation for application in agriculture had to be perpetually carried out.

Nowadays, heritage is eventually inexistence, inaccessible and design decision due to the constructions of new buildings and sites. Various techniques in virtual reality have been proposed in producing virtual heritage. Improper management of virtual heritages in their virtual environments in terms of location and link may cause delivering information unsystematically. This paper is purposed to model virtual heritage environments for one case study of sheltered pavilion using Hierarchy-Embedded Virtual Objects technique. This technique is a hierarchical, tree-structured approach that emulates a tree structure with a set of linked nodes. Three different virtual heritage environments have been published through the tree structure in HEVO Editor. Organizing Editor has enables virtual heritages to be managed in terms of location and link. The resulted virtual heritage environments can be visualized, interacted and navigated through Viewing Editor. These virtual heritage environments are believed to be significant for learning the VH and presenting the values inculcated inside them. Challenges of the modelling technique, research quantification, modelling goals and VH attractions also have been discussed for advanced consideration to model VH.

This paper proposed new model for data retrieval. This technique will improve time for data retrieval. Document Object Method (DOM) will used as key to read XML document. This model will created cache as a temporary file. After retrieve data from database, the data will saved at cache. This model is very efficient compared to old model. Experimental result shows this model produce better performance for data retrieval.
