Abstract
English
Carrageenan is a polysaccharide compound product produced from carrageenophyte seaweed extraction, one of which is Kappaphycus alvarezii. The yield and other characteristics are conventionally produced from an extraction process and have different results. This study aims to explore and optimize the characteristics of carrageenan produced by treating sample preparation with two types of precipitants at specific concentrations, setting the timing during the extraction process, and examining the interaction of these three treatments on the carrageenan characteristics. The results obtained showed that the yield value, acid-insoluble ash (AIA) content, and viscosity were influenced by the preparation method, specifically by chopping the seaweed before extraction. Additionally, the characteristics of the gel strength were influenced by the preparation method, specifically by blending the seaweed. The use of KCl precipitant affects the water content, AIA content, and viscosity, while the CaCl₂ precipitant affects the yield value and gel strength. 1-hour extraction process affected the characteristics of carrageenan for AIA content and gel strength, while extraction for 2 hours affected the yield value, water content, and viscosity. The interaction of 8% KOH solvent by cutting sample treatment, extracted for 2 hours and using KCl precipitant, produced good carrageenan characteristics for water content, AIA content, and viscosity.

Karaginan merupakan produk senyawa polisakarida yang dihasilkan dari ekstraksi rumput laut jenis karaginofit, salah satunya adalah jenis Kappaphycus alvarezii. Rendemen dan karakteristik lain yang secara konvensional dihasilkan dari suatu proses ekstraksi memiliki hasil yang berbeda-beda. Penelitian ini bertujuan mengeksplorasi dan mengoptimlisasi karakteristik karaginan yang dihasilkan dengan memberi perlakuan terhadap persiapan rumput laut yang digunakan, jenis penjendal berbeda dengan konsentrasi tertentu, waktu yang ditetapkan selama proses ekstraksi dan interaksi dari ketiga perlakuan terhadap karakteristik karaginan tersebut. Hasil penelitian memperoleh karakteristik nilai rendemen, kadar abu tak larut asam (ATA), dan viskositas dipengaruhi oleh cara preprasi dengan memotong rumput laut sebelum diekstraksi, selanjutnya, karakteristik kekuatan gel dipengaruhi oleh cara preparasi dengan memblender rumput laut. Penggunaan presipitan KCl memberikan pengaruh terhadap nilai kadar air, kadar ATA dan viskositas, sedangkan presipitan CaCl2 mempengaruhi karakteristik dari nilai rendemen dan kekuatan gel. Proses ekstraksi yang berlangsung selama 1 jam berpengaruh terhadap karakteristik karaginan untuk kadar ATA dan kekuatan gel, sedangkan ekstraksi selama 2 jam mempengaruhi nilai rendemen, kadar air dan viskositas. Interaksi pelarut KOH 8% dengan perlakuan sampel yang dipotong-potong, diekstraksi selama 2 jam dan menggunakan larutan penjendal CaCl2 menghasilkan karakteristik karaginan yang baik untuk nilai rendemen, kadar air, kadar ATA, kadar sulfat dan kekuatan gel. Kata kunci: Karaginan, preparasi sampel, lama ekstraksi, presipitan
