Main Author from Politeknik Port Dickson.
Abstract - The issue of global warming was intensifies said among of the researchers recently. It happens more so in the urban areas where most buildings were built too high and dense with structures, vehicles, goods, dwellers, visitors, wastes or any sources of pollutants . The price of the allocated land in urban areas was too expensive and very limited for designers to explore the green elements to implement and improve the ecological habitats as well as to beautify the urbanscape. The idea of the green wall system on façade is one of the most favourite solutions for designers to achieve the green building design which currently related to energy efficiency. This system can be placed during the design concept stages or later be installed to the existing building wall commonly known as a Double Skin Façade (DSF). This particular system is not new in the market. However, there is growing tendency from the architects to put it into practice for certain buildings at certain places even the construction types can be differ from one location to another. This paper represents the findings of a team who have conducted an initial investigation into double skin cladding systems in Malaysia. The study focused on the flexibility approaches that improved indoor climate and reduced use of energy if it has been designed properly to meet the climate changes. It also discussed about the advantages and disadvantages of Double Skin Facade which found in different literature sources as described. Further discussion is about the implementation of the system in Malaysia based on the examples of office buildings.

Abstract - Pepper agricultural industries are one of the most beneficial to the Sarawak economy as it's known for high quality products. In order to ensure continuous expand in pepper industries, many efforts have been made, including introducing efficient processes through automation and advanced technology to maintain the quality of the end product. One of major requirement in pepper processing in the industries is the sorting process. Due to the nature of the peppercorns during its ripening process, each peppercorn will ripen at different time and requires sorting process which normally been done manually choosing or picking. To ensure the best quality product, the peppercorn first must be selected and the over ripe peppercorns have to be eliminated as the moisture content and the flesh from over ripe peppercorn will promote the growth of fungi and speed up the decaying of the peppercorns. In order to help the pepper industries to improve the product quality, a concept of sorting machine was brought forward. The main objective of this paper is to develop a sorting machine concept that can be used to sort the peppercorn based on its colour identification through automated and precise process. This process is a guarantee process that can improve the quality of the product. This concept also developed to introduce a more efficient and hygienic process in peppercorns processing.
