ABSTRACT The purpose of this study was to determine the effect of NaCl soaking time and drying time on the quality of belitung taro flour (Xanthosoma sagittifolium). This study used a factorial design using 2 factors: NaCl soaking time (0, 30, and 60 minutes) and drying time (3, 4 and 5 hours) consisting of 9 treatments and 3 replications. The parameters observed included chemical parameters (moisture, ash, starch, calcium oxalate, and crude fiber content) and physical parameters (yield, bulk density and color value L *). The results of the research data were analyzed using analysis of variance alpha 5% and if there were significant differences it was tested further using the Duncan Multiple Range Test. The results showed that the treatment of soaking time in NaCl solution had a significantly effect on chemical parameters (moisture, ash, starch, calcium oxalate, and crude fiber content) and physical parameters (yield, bulk density, color value L*) . The drying time gave significantly effects on chemical parameters (moisture, ash, starch, calcium oxalate, and crude fiber content) and physical parameters (yield and bulk density). The interaction between NaCl soaking time and drying time gave a significantly effect on calcium oxalate content. The best treatment is 60 menit NaCl soaking time and 5 hours drying time (L3P3) with 3.56% moisture, 1.31% ash, 64.36% starch, 337.82 mg/100g calcium oxalate, 2.5% crude fiber content, 19.31% yield, 0.71 g/ml bulk density, and L* color value 92.28 that has met the SNI quality requirements for cassava flour.

Penelitian ini menggunakan Rancangan Faktorial menggunakan 2 faktor yaitu faktor lama perendaman dalam larutan NaCl (0, 30, dan 60 menit) dan faktor lama pengeringan (3, 4 dan 5 jam) yang terdiri dari 9 perlakuan dan 3 ulangan. Parameter yang diamati meliputi parameter kimia (air, abu, pati, kalsium oksalat, dan kadar serat kasar) dan parameter fisik (rendemen, densitas kamba dan warna nilai L*). Data hasil penelitian dianalisis menggunakan analisis keragaman pada taraf nyata 5% dan apabila terdapat beda nyata maka diuji lanjut menggunakan uji Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa perlakuan lama perendaman dalam larutan NaCl memberikan pengaruh yang berbeda nyata terhadap parameter kimia (kadar air, abu, pati, kalsium oksalat, dan serat kasar) dan parameter fisik (rendemen, densitas kamba, warna nilai L*). Perlakuan lama pengeringan memberikan pengaruh yang berbeda nyata terhadap parameter kimia (air, abu, pati, kalsium oksalat, dan kadar serat kasar) dan parameter fisik (rendemen dan densitas kamba). Interaksi antara lama perendaman dalam larutan NaCl dengan lama pengeringan memberikan pengaruh yang berbeda nyata terhadap kadar kalsium oksalat. Perlakuan terbaik yaitu lama perendaman dalam larutan NaCl 60 menit dan lama pengeringan 5 jam atau L3P3 dengan kadar air 3,56%, abu 1,31%, pati 64,36%, kalsium oksalat 337,82 mg/100g, serat kasar 2,5%, rendemen 19,31%, densitas kamba 0,71 g/ml, dan warna nilai L* 92,28 yang telah memenuhi syarat SNI mutu tepung singkong. Kata Kunci: lama perendaman, lama pengeringan, NaCl, talas belitung, tepung
ABSTRAK<br /><br />Daun singkong pahit (Manihot esculenta)memiliki kandungan antinutrisi berupa asam sianida (HCN) yang tinggi, namun HCN dapat di degradasi dengan bakteri rumen. Penelitian ini bertujuan untuk mengamati karakteristik produk dan efektivitas enkapsulasi bakteri pendegradasi sianida dengan masa simpan (0, 1, 2, 3, 4, 5, 6, 7, 14, 21, 28 hari) pada suhu ruang. Peubah yang diamati adalah karakteristik produk dan viabilitas bakteri pendegradasi sianida terenkapsulasi. Data yang diperoleh dianalisa dengan sidik ragam (ANOVA) menggunakan program SPSS 16.0. Hasil penelitian menunjukkan bahwa lama penyimpanan berpengaruh terhadap perubahan warna dan bentuk dari produk hasil enkapsulasi. Penyimpanan produk enkapsulasi bakteri pendegradasi sianida selama 3 hari tidak mempengaruhiviabilitas bakteri dibandingkan kontrol. Namun demikian semakin lama penyimpanan produk enkapsulasi bakteri sampai hari ke 28 nyata menurunkan (P<0.05) viabilitas bakteri.Hasil penelitian dapat disimpulkan bahwa dengan teknik enkapsulasi dapat mempertahankan viabilitas bakteri pendegradasi sianida.<br /><br />Kata kunci: bakteri pendegradasi sianida, karakteristik produk, penyimpanan,viabilitas<br /><br />ABSTRACT<br /><br />Bitter cassava leaves have high antinutrients in the form of cyanide acid (HCN), but HCN can be degraded with rumen bacteria. This research aimed to observe the product characteristics and the effectivity of cyanide degradation bacteria capsulation with different length of storages (0, 1, 2, 3, 4, 5, 6, 7, 14, 21, 28 days)in the room temperature. The observed variables were product characteristics and viability of cyanide degrading bacteriacapsulation. The data obtained were analyzed by Analysis of variance (ANOVA) using SPSS 16.0 program. The results showed that storages duration affected the color and shape of cyanide degradation bacteria capsulation products. The storage of capsulated HCN degrading bacteria up to 3 days did not affect the viability of bacteria compared to the control treatment. However, the longer storage of capsulated bacteria up to 28 days, significant decreased (P<0.05) the viability of the bacteria. It is concluded that capsulation of cyanide degrading bacteria could maintain the viability of bacteria.<br /><br />Keywords: cyanide degradation bacterial, product characteristics, storage, viability
