Abstract
INDONESIA
Edible coating merupakan salah satu metode untuk memperpanjang umur simpan dan mengurangi penurunan kualitas produk pertanian yang bersifat perishable seperti stroberi (Fragaria x ananassa). Edible coating dapat dibuat dari bahan polisakarida seperti pati singkong (Manihot esculenta) dan pati ganyong (Canna edulis) agar aman untuk dikonsumsi. Pada peneitian ini dilakukan pengkombinasian dengan suhu penyimpanan. Penelitian ini bertujuan untuk : mengetahui pengaruh jenis pati bahan edible coating, pengaruh suhu penyimpanan dan pengaruh kombinasi perlakuan suhu penyimpanan dengan jenis pati bahan edible coating terhadap kualitas stroberi (Fragaria x ananassa). Parameter yang diamati meliputi susut bobot, laju respirasi, warna, tekstur dan kandungan vitamin C.
Penelitian dilaksanakan pada bulan April-Mei 2013 di Laboratorium Fisiologi Tumbuhan Jurusan Biologi Fakultas Sains dan Teknologi Universitas Islam Negeri Maulana Malik Ibrahim Malang. Penelitian ini merupakan penelitian eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor perlakuan dan 3 kali ulangan. Faktor perlakuan pertama yaitu jenis pati bahan edible coating yang terdiri dari tanpa aplikasi edible coating, dengan aplikasi edible coating berbasis pati singkong (Manihot esculenta) dan dengan aplikasi edible coating berbasis pati ganyong (Canna edulis). Faktor perlakuan kedua yaitu suhu penyimpanan yang terdiri dari suhu ruang dan suhu dingin. Pada penelitian ini juga dilakukan pengkombinasian antara jenis pati bahan edible coating dan suhu penyimpanan secara faktorial. Pengamatan dilakukan setiap 2 hari sekali selama 8 hari penyimpanan. Data yang diperoleh dianalisis dengan Analisis of Variance (ANOVA) Two Way dengan taraf kepercayaan 5%.
Hasil penelitian menunjukkan jenis pati bahan edible coating berpengaruh terhadap kualitas stroberi (Fragaria x ananassa). Pengaruh yang diberikan antara coating berbahan dasar pati singkong (Manihot esculenta) tidak berbeda nyata dengan coating berbahan dasar pati ganyong (Canna edulis). Akan tetapi, kedua coating berpengaruh nyata dibandingkan buah stroberi (Fragaria x ananassa) tanpa pelapisan edible coating. Buah stroberi (Fragaria x ananassa) yang disimpan pada suhu dingin memiliki kualitas yang lebih baik dibandingkan buah stroberi (Fragaria x ananassa) yang disimpan pada suhu ruang. Kombinasi perlakuan yang paling baik untuk mempertahankan kualitas buah stroberi (Fragaria x ananassa) adalah penyimpanan suhu dingin dengan aplikasi edible coating berbasis pati singkong (Manihot esculenta) (P1S2).
ENGLISH
Edible coating is one method to extend the storage age and decrease the loss of quality agricultural products are perishable like strawberries (Fragaria x ananassa). Edible coatings can be made from polysaccharide material such as cassava (Manihot esculenta) starch and canna (Canna edulis) starch to be safe for consumption. In this research, combining with the storage temperature. The aims of this study are to know the effect of type of starch edible coating materials, the storage temperature and combination treatment the storage temperature with type of starch edible coating material on the quality of strawberry (Fragaria x ananassa). Parameters observed is weight loss, respiration rate, color, texture and content of vitamin C.
This study was conducted in April-May 2013 in the Laboratory of Plant Physiology Department of Biology, Faculty of Science and Technology of the State Islamic University of Maulana Malik Ibrahim Malang. This study is an experimental study using a Completely Randomized Design (CRD) with 2 factors and 3 repetitions. The first factors are the type of starch edible coating material consisting of whitout edible coating application, with the application of edible coatings made from cassava starch (Manihot esculenta) and with the application of edible coating made from canna starch (Canna edulis). The second factor is the storage temperature consisting of room temperature (27-28˚C) and cold temperature (8-10˚C). In this study, well done combining the type of starch edible coating materials and storage temperature. The observation is done two days for 8 days of storage. The data that have been obtained are analyzed by variance (ANOVA) two ways analysis with confidence level 5%.
The result of this study shows that the type of starch edible coating material influence on the quality of strawberry (Fragaria x ananassa). Influence exerted between the coating made from cassava starch (Manihot esculenta) is not significantly different from coating made from canna starch (Canna edulis). However, the second coatin significantly compared with strawberries (Fragaria x ananassa) without edible coating aplication. Strawberries (Fragaria x ananassa) are stored at cold temperature has better quality than strawberries (Fragaria x ananassa) were stored at room temperature. The combination treatment that is best for maintaining quality of strawberries (Fragaria x ananassa) is cold storage with application edible coating made from cassava starch (Manihot esculenta) (P1S2).
