ABSTRAKJenis pengemas biodegradable saat ini sangat diperlukan untuk mengurangi penggunaan plastik sintetik, di antaranya dengan pengembangan pengemas edible film yang lebih ramah lingkungan. Karagenan dan kitosan merupakan polimer alam yang berpotensi menjadi bahan dasar dalam pembuatan edible film. Penelitian pembuatan edible film berbahan dasar karagenan dan kitosan dengan metode layer-by-layer telah dilakukan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi karagenan dan kitosan yang berbeda terhadap kualitas edible film yang dihasilkan. Karakterisasi film yang dilakukan meliputi uji kuat tarik, elongasi, kelarutan, water vapour permeability (W VP) dan morfologi permukaan. Rancangan percobaan yang digunakan adalah faktorial 2 faktor dengan variasi karagenan (1,0%, 1,5%, 2,0%, 2,5%) dan variasi kitosan (0,5%, 1,0%, 1,5%, 2,0%). Hasil penelitian menunjukkan bahwa setiap kombinasi konsentrasi karagenan dan kitosan menghasilkan nilai yang berbeda-beda. Kenaikan konsentrasi karagenan dan kitosan tidak selalu berbanding lurus terhadap kenaikan nilai kuat tarik, elongasi, kelarutan, WVP dan morfologi permukaan edible film. Secara umum, dari seluruh perlakuan yang ada dapat disimpulkan bahwa kombinasi karagenan 2,5% dan kitosan 1,0% adalah formulasi terbaik. KATA KUNCI : biodegradable, edible film, karagenan, kitosan ABSTRACTBiodegradable packaging development particularly for maintaining the quality and shelf life of food products is necessarily needed. Carrageenan and chitosan are natural polymers that are potential for raw materials of biodegradable films production. Research on the making of carrageenan and chitosan-based films has been carried out using layer-by-layer method. This study aimed to determine the effects of various concentrations of carrageenan and chitosan on the quality of edible films. The parameter observed were tensile strength, elongation at break, solubility, water vapor permeability (WVP) and surface morphology. The experimental design used were variations of carrageenan concentrations i.e 1,0%, 1.5%, 2,0%, 2.5% and chitosan i.e. 0.5%, 1,0%, 1.5%, 2,0%. The results showed that each combination of carrageenan and chitosan concentrations produced different film characteristic values. The increasing of carrageenan and chitosan concentrations was not linearly affected all the parameters including the tensile strength, elongation at break, solubility, WVP and surface morphology. Based on the findings, it can be concluded that the combination of 2.5% carrageenan and 1,0% chitosan was the best formulation.

“…Larutan KOH memberikan hasil abu terbaik karena ikatan kation K + yang bereaksi dengan karaginan (Asikin & Kusumaningrum, 2019). Tinggi rendahnya kadar abu dipengaruhi adanya garam mineral lain pada rumput laut seperti natrium dan kalsium (Kumayanjanti & Dwimayasanti, 2018). Kadar abu cara native memiliki nilai terendah diduga tidak adanya ikatan senyawa alkali selama proses ekstraksi, sehingga kandungan mineral hanya berasal dari lingkungannya.…”

“…Hal ini diduga tidak digunakannya larutan alkali. Kekuatan gel karaginan dipengaruhi konsentrasi pelarut, pH, suhu, dan waktu ekstraksi (Kumayanjanti & Dwimayasanti, 2018;Meiyasa dan Tarigan, 2018). Ditambahkan (Rhein-Khudsen et al, 2017) hidrokoloid yang diekstraksi dengan air mengandung jumlah sulfat lebih tinggi dibandingkan cara alkali.…”

Analisis Parameter Fisika dan Kimia Karaginan Kappaphycus alvarezii Doty 1985 (Florideophyceae : Solieriaceae) Dengan Variasi Ekstraksi dari Perairan Bluto

Kappaphycus alvarezii merupakan rumput laut merah penghasil karaginan yang dimanfaatkan dalam berbagai industri dan diperoleh melalui ekstraksi. Ekstraksi umumnya menggunakan larutan alkali sebagai pelarut dalam proses pemanasan maupun perendaman. Ekstraksi tanpa larutan alkali masih jarang dilakukan. Ekstraksi cara alkali, non-alkali maupun pre-treatment alkali mempengaruhi kualitas karaginan sehingga penelitian ini perlu dilakukan. Tujuan penelitian untuk memperoleh karaginan kualitas terbaik dari 3 metode ekstraksi. Parameter yang diambil meliputi rendemen, kadar air, kadar abu, kekuatan gel, viskositas dan analisis FTIR. Karaginan dihasilkan melalui ekstraksi secara alkali dengan pemanasan KOH, pre-treatment alkali dengan perendaman KOH sebelum pemanasan dan ekstraksi native pemanasan dengan air suling. Hasil penelitian didapatkan nilai rendemen terbaik dengan metode alkali (36,68±2,33%). Kadar air terbaik metode pre-treatment (3,91±0,84%). Kadar abu terbaik metode alkali (32,7±2,42%). Kekuatan gel terbaik dengan metode alkali (519±29,01g/cm2). Viskositas terbaik metode native (70,43±0,74 cPs). Hasil FTIR menunjukkan sampel yang dihasilkan jenis kappa karaginan. Kappaphycus alvarezii produces carrageenan which is widely used for industrial and obtained through extraction. Generally the extraction is using an alkaline solution as a solvent of heating or soaking process. Extraction without alkaline solution is infrequently performed. Different extraction methods affect the quality of the carrageenan, therefore the research has to be done. The purpose of this research is to obtain the best quality carrageenan from 3 different extraction methods. The parameters performed yield, water content, ash content, gel strength, viscosity and FTIR analysis. Carrageenan are produced through alkaline extraction treatment with KOH, pre-treatment alkaline with KOH and native extraction with distilled water. The results showed the best yield was alkaline method (36.68±2.33%), the best water content was pre-treatment method (3.91±0.84%), the best ash content was the alkaline method (32.7±2.42%), the best gel strength was the alkaline method (519 ± 29.01g/cm2), the best viscosity was the native method (70.43±0.74 cPs). Analysis FTIR showed the samples produced kappa carrageenan.

“…It is influenced by three basic kinds of stuff such as cultivation, harvesting period, and drying process (Anggadiredja et al, 2006). Furthermore, the difference in cultivation place is another influential factor in its quality (Kumayanjati & Dwimayasanti, 2018). Another factor is quality seed selection and supply, which is cheap, easy, massive, and sustainable (Sarira & Pong-Masak, 2018).…”

Quality is a crucial factor of an industry. PT XYZ is an exporter and distributor company of seaweed in Makassar city. It exports various varieties of seaweed, one of them is Eucheuma cottonii. Quality must be maintained to preserve and increase company image or reputation and consumer satisfaction. The study aims to improve quality of seaweed through quality control by using Statistical Quality Control (SQC) method. Receiving data of Eucheuma cottonii seaweed obtained from 30 sample groups, each group contains three different samples. Analysis on the process capability then was carried out so that the obtained score of process capability ratio was 0.35<1 and the process capability index score was-0.12<0. It can be concluded that the receiving process of seaweed in this company was incapable and need improvement to increase receiving process capability of seaweed. Several factors caused this incapable process were the unskilled human resources on seaweed handling in material receiving process and during distribution process from the farmer, the limitation of reliable measuring instruments, and the lack of constructive partnership between farmers, suppliers, and industry. Hence, this study suggested to improve skills of the employee, supplier, and farmer regarding seaweed cultivation and handling, to provide more reliable measuring instruments, and to develop constructive partnership development among farmer, supplier, and industry as an improvement of seaweed quality on receiving process.
