Just like other paper/plastic/aluminum (PPA) composites, Tetra Pak-package-material (Tetra Paks) has excellent water and vapor barrier abilities, and is widely used in food and beverage packaging industry. However, serious environmental problem follows due to its long service life. In this paper, a novel electromagnetic shielding composite board was developed with recycled Tetra Paks and copper-iron mixed fibers. The influence of Cu/Fe ratio and mat configuration on board shielding effectiveness (SE), volume resistivity (VR) and mechanical properties were investigated. The results showed that the boards with copper-iron mixed fiber layers showed better electromagnetic shielding performance than those with only iron or copper fiber layer. The SE of the boards was improved with higher copper fiber content. The location of the metal fiber layers in the mat had a significant influence on board electromagnetic shielding performance. A symmetrical sandwich structure was found beneficial to better shielding performance, and in the same condition of wave frequency and shielding material thickness, the shielding system with a Fe core exhibited better shielding performance than that with a Cu core. The ratio of Cu/Fe and the configuration of mat both had significant influences on mechanical properties of the boards. It can be concluded that qualified electromagnetic shielding composite board could be produced with Tetra Paks wastes and copper-iron mixed fibers. Showing both environmental and economic values, this type of board could be considered as an alternative material used in packaging, interior finish, furniture, and other applications.

Cultural association analysis of color is an approach to know color from the side of culture. Unlike the previous color studies which see the color from the aspect of psychology, this research of color aims to provide insight based on the colors from local culture. Johannes Itten’s theory of color was used as a basis of thought in this research. The theory was reflected to Indonesian cultures, and this time, represented by Java island. Research used qualitative method by literature study, interviewing the color experts, historians and artists, visiting cultural centers. Results of the research are in the form of morphological matrix cultural over color. Matrix of analysis resulted in argument and study proposal. Students implemented the color schemes from 5 big cities in Java. They were asked to change the color composition of food and beverage packaging. Students may use, explore, and maximize the principle of color in visual communication to achieve contrast and balance.

In preparing Malioboro as a 24-hour tourist area, garbage and waste can cause negative impacts. This study aims to identify the daily amount and factors of waste in the study area, namely the gate of Kepatihan sayap Malioboro area, using a phenomenological and rational approach. In this study, following the thoughts of B. Sommer (1980) about the person center map and place center map so that the movement of Malioboro visitors and the activities of visitors and street vendors in a certain period with a certain study area. The types of waste that most often appear are food and beverage packaging, plastic bags, plastic straws and cigarette butts. The maximum volume of waste that can be accommodated in the trash per day is 3 x 1.458 m3 = 4,374 m3 per day. Awareness of the importance of cleanliness is important through socialization in the form of a flash mob. The next suggestion is to maximize the function of the trash can by separating it according to its type.
