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.
Dioscorea hispida (D.hispida) is a poisonous plant which their tuber contains toxic poison and can be consumed after the poison or dioscorine is removed. The tubers were peeled, sliced and soaked in flowing water (river) up to 7 days during traditionally detoxified process. Due to the traditional processing methods for removal of dioscorine is difficult to practice, we develop two types of equipment (wavy and spin) based on their water circulation operations. This project consisted the stages of design, fabricate and testing for the development of stand alone dioscorine removal equipment. Survival of Cyprinus carpio fish in slicing tuber of D.hispida extraction was used as a tool for detection of dioscorine removal. Results indicate that water circulation of spin operation was more effective compared to wavy type based on their capability of increasing pH activity and survival of fish as in D.hispida tuber during 6 hours of detoxified process. Therefore, this unique equipment can reduce the preparation time and also handling process of detoxified D.hispida thus making it to be more hygienic as compared to the traditional method in which river is used as a medium for dioscorine removal. The manual operation for water inlet and outlet for dioscorine removal system will replace for automatic operation by using On / Off solenoid valve while the Peripheral Interface Controller (PIC) is use for controlling input and output signal from sensor, solenoid valve and motor pump. Conceptually, the system will enhance with automatic timer which will pour out the dirty water and refill new water from inlet automatically.
Ubi Gadong (Dioscorea hispida) is a toxic plant which contains toxic poison. It can only be consumed after the poison of dioscorin is removed. It is normally found in wildlife forest and planted in clay soil condition in Asia region. The advancement of technology should introduce in most important area; agriculture, as for benefit of mankind. The solid modeling software may use for design, model and simulate the workability of the designed equipment in CAD environment system. The simulation analysis will make the designer choose the best decision for fabrication stage of agriculture mechanization tool. The farm mechanization for ubi gadong is help to produce the good quality and output in this new exploration of wildlife food for commercialization.
