Ironically, most plastics are only being used once and discarded to the landfills and oceans. This phenomenon will be one of the most crucial problem of the century. Hence, a lot of research has been done to study the potential usage of plastic waste in various field. Thus, this study was aimed to find an alternative way to recycle plastics waste into a beneficial product without polluting the environment. PLINK enables those plastic waste to become a useful plastic ink in the form of crayon and can be used widely in the arts and batik making field. Py.rolysis method has been used to extract crude oil from the plastic waste will then undergo petroleum distillation to get petrol that is then change into wax by deoiling. Then organic color pigment is aded to the wax to create a crayon mixture in order to obtain PLINK. PLINK has been tested by the students from the Faculty of Arts and Design at UITM Shah Alam in their art painting classes. Results showed that PLINK has been one of the most green and compatible with the commercial crayons in the market. The simple techniques that need to be apply in using PLINK especially as batik mixture and dyes for shirts was accredited to be green and eco-friendly for the users. PLINK has been proven to be one of the best ways to make abundance of plastic waste more useful and provide a greener way of using crayon in arts and batik making field
Excel as an aid to find parametric arc length in complex graph for undergraduate students
No full textThis study uses a method using excel to figure out if the graph function of Excel trendline is a liable function to aid in calculating parametric arc length for undergraduate students learning parametric equations and parametric graphs. Since there are not many software out there that are easily obtainable by students to use as a reference for them to tackle complex graph where it’s function is complicated and hard to obtain. Namely, functions that have a high power or complex combination of trigonometric functions. This method uses the Excel’s trendline function within the software to get the mathematical functions and also the graph by only using data obtain via hand drawn graph of a map route. The data then can be manipulated within excel into several segments to make out easier graph for use in calculation of parametric arc length. With this method many students and professionals that needs to find the parametric arc length of a graph can use the method as a substituted or an alternative to calculate parametric arc length using only excel. Furthermore, this method have the potential to be commercialize into being use as a way to engage students into understanding parametric concept more interactively since it can be use in real life by having them make their own graph of their surrounding and extrapolating them into using excel
