Main Material

Biodegradable plastics are plastics that will decompose in nature with the help of microorganisms. The use of starch as the main material of plastic manufacturing has great potential because in Indonesia there are different starch crops. To obtain bioplastics, starch is added to the glycerol, in order to obtain a more flexible plastic and elastic. This study reviews the use of cassava starch and glycerol skin asa base for the manufacture of biodegradable plastics. The purpose of this research is to know the effect of adding glycerol in the process of making biodegradable plastic from cassava peel waste. In this research, the study of bioplastic manufacturing mixed starch with glycerol as a plastisizer to do variations of the glycerol. The results obtained in the form of a thin sheet of plastic (plastic film) that have been tested mechanical properties obtained optimum data variables namely cassava starch composition 3,5%, and the power og pull 0,02122Mpa, and plastic film storage time for 14 days.

Abstract The paper presents an impact of the addition of industrial machining chips on the mechanical properties of polymer concrete. As an additional filler, six types of industrial waste machining chips were used: steel fine chips, steel medium chips, steel thick chips, aluminium fine chips, aluminium medium chips, and titanium fine chips. During the research, the influence of the addition of chips on the basic parameters of mechanical properties, i.e., tensile strength, compressive strength, splitting tensile strength, and Young’s modulus, was analyzed. On the basis of the obtained results, conclusions were drawn that the addition of chips from machining causes a decrease in the value of the mechanical properties parameters of the polymer concrete even by 30%. The mechanism of cracking of samples, which were subjected to durability tests, was also explored. In addition, it was found that some chip waste can be used as a substitute for natural fillers during preparation of a mineral cast composition without losing much of the strength parameters.
