Abstract

Biodegradable plastics are an important thing to consider in order to meet environmentally friendly plastics. This study aims to determine the potential of crab waste and cassava peel waste as raw material for biodegradable plastics. This research was conducted in the Laboratory of Microbiology Industry at the Technical Industry Academy of Makassar in Januari-April 2022. The research method used was an experimental method with simple statistical analysis techniques. This research uses three parameters : the power of elasticity, resistance to temperature and the ability to decompose. The result that chitosan concentration of 1 gram, 5 grams of starch and cassava peel, 15 ml glycerol gave the best results compared to the two other treatments at 4,623% elongation values​​, degraded faster and has a resistance to temperatures up to 100 ℃ for 2 hours

Abstract

Indonesia Power PLTU Barru OMU menggunakan batubara jenis lignit sebagai bahan bakar pada boiler. Pelumas bekas di PT. Indonesia Power PLTU Barru OMU merupakan salah satu limbah yang belum diolah lebih lanjut yang masih mengandung energi. Untuk meningkatkan kualitas batubara dengan menggunakan pelumas bekas memerlukan suatu metode yang disebut upgrading brown coal. Penelitian ini bertujuan untuk menganalisis kualitas batubara dengan menggunakan pelumas bekas dengan mengukur parameter nilai kalori, nilai total sulfur, kadar moisture, kadar volatile matter, kadar ash content dan kadar fixed carbon pada sampel sebelum dan setelah dilakukan upgrading brown coal. Penelitian ini bersifat eksperimental, yaitu dengan melakukan pengujian kualitas batubara dengan menggunakan pelumas bekas. Berdasarkan penelitian yang telah dilakukan dapat disimpulkan bahwa penggunaan pelumas bekas dapat meningkatkan kualitas batubara melalui proses upgrading brown coal. Hasil pengujian parameter kualitas menunjukkan bahwa sampel kode D memiliki kualitas baik dengan nilai kalori 7252,86 kal/g, nilai total sulfur 0,129%, kadar moisture 3,055%, kadar volatile matter 69,875%, kadar ash content 5,06% dan kadar fixed carbon 22,51%. Namun, sampel kode D tidak mampu menurunkan kadar volatile matter dan menaikkan fixed carbon.
