Abstract

This study discusses composite polymer of LLDPE and PLA at a ratio of 100: 0, 80:20, 60:40, 40:60, 20:80, 0: 100 with 4 phr LLDPE-g-MA compatibilizer. The process of making composite was performed using rheomix, which was then molded into thin sheets using hydraulic hot press to test its mechanical properties, i.e. SEM, TGA and biodegradable. The test results of mechanical properties (tensile strength and elongation at break) showed that the less the composition of PLA in the composite, the higher the mechanical properties. SEM composite test results have indicated that the LLDPE/PLA composite has a smooth surface, indicating good compatibility between LLDPE and PLA. The TGA testing produced thermal degradation in the composite sample as the PLA compositions decreased. The biodegradable test results showed that the more the PLA composition increased, the higher the missing mass of the compositesamples. Based on the test results, composite LLDPE/PLA can be used as a polybag plastic because it has strong mechanical properties and environmentally friendly due to the fact that it can be degraded by microorganisms.

Abstract

This study aims to determine the level of acidity in the rainwater in the industrial area of East Jakarta. The research was done by using a multimeter (Waterproof Tester). With these tools, it can be seen pH and temperature in the rainwater. The results shown that the rainwater in the area of Bekasi tends to be normal because it is still in the average and standard. Although these areas are industrial areas, airports, and many transportation passes, the industrial area still have green places.

Abstract

The aim of this study is to obtain a dye source which is can be degraded easily. Themajority of natural dyes extracted from plants is easily degraded dye. Plants that can be used as a coloring agent such as jackfruit wood (Artocorpusheterophyllus) taken from the morin containing a yellow dye. This study aims to find the best extraction time of morin from jackfruit sawdust using some solvent (Ethanol, Hexane and Acetone). The research was carried out in chemical laboratories in PT Sanova. From the research that has been done, found the best extraction time for 2hours with a yield of 8.36% morin.
