Based on these results, it can beconcluded that breed chicken eggshells are potential sources for the preparation of CaO catalyst material to producebiodieselfromwastecookingoil.Thisfindingisveryusefulforfurtheropti-mizationofmasscatalystsheterogeneousCaOfrombreed chicken eggshellsincludingthecommercial productionofbiodiesel.Keywordsbiodiesel,CaOheterogeneouscatalyst,transesterification,wastecookingoil, breed chicken eggshell date: 2022-04-05 type: Thesis type: NonPeerReviewed format: text language: en identifier: http://repository.poltekkes-tjk.ac.id/id/eprint/4232/1/Turnitin_utilization%20of%20Breed%20Chicken%20Eggshells%20for%20Biodisel.pdf identifier: Djayasinga, Rodhiansyah and setiawan, Andi and Purnomo, Agus and Amien, Ahmad Zakaria (2022) TURNITIN_Utilization of Breed Chicken Eggshells for Biodiesel Preparation from Waste CookingOil.
