Abstract

Edible film made up of modified tapioca was used to wrap tempeh and its shelf life estimation was determined. The edible films must be capable of evenly aerating and maintaining moisture without causing condensation in order mycelium to be able to grow and produce high-quality tempeh. The experiment was carried out in completely randomized design with two main factors of storage temperature and time. An accelerated shelf life test at 17oC, 27oC, and 37oC with an Arrhenius model was used to calculate the shelf life, and water content was used as quality parameter indicator. The result showed that modified-tapioca based edible film made from fermentation of tapioca by Saccharomyces cerevisiae was characterized as having elongation of 11.40 %, tensile strength of 408.37 MPa, thickness of 0.88 mm and WVTR of 12.60 g/m2/h. Rate constant of water content decrease in edible film wrapped tempeh based on Arrhenius model was 0.3832 % day-1 and Ea was 10.296 kkal/gmol, while that of in PP-plastic wrapped tempeh was 0.3831% day-1 and Ea was 9.998 kkal/gmol. The shelf life of edible film wrapped tempeh was 9.39 days at 27oC, 5.18 days at 27oC, and 2.96 days at 37oC, while shelf life of PP-plastic wrapped tempeh was 8.64 days at 17oC, 4.85 days at 27 oC, and 2.82 days at 37oC. Therefore, it can be concluded that modified tapioca based edible film increased the shelf life of tempeh.

Abstract

Today, there are still very few product variations for product development from Heterotrigona itama pure honey, so it is necessary to develop Heterotrigona itama pure honey products. This study aims to determine the best Heterotrigona itama pure honey formulation for making cold lemon tea. The research consisted of three stages: dehumidification of Heterotrigona itama honey, formulation of cold lemon tea drink, and continued testing in the form of hedonic tests and proximate analysis of the best formula. The research used a completely randomized design (CRD) with the formulation of Heterotrigona itama honey and white crystal sugar, including 45 grams of sugar (F0), 23 grams of honey and 33.75 grams of sugar (F1), 46 grams of honey and 22.5 grams of sugar (F2), 69 grams of honey and 11.25 grams of sugar (F3), and 92 grams of honey (F4) with F0 as the control formulation. The data were analyzed using variance (ANOVA) followed by the Honest Significant Difference (BNJ) test. The formulation of Heterotrigona itama honey with a concentration of 46 grams and white crystalline sugar with a concentration of 22.5 grams (F2) in 500 ml of water is the best formula. The public accepts it for making cold lemon tea fresh drinks with a pH value of 3.09, reducing sugar of 4.6645 %, ash of 0.391 %, and total titrated acid of 2.4826%.

Abstract

Nata de banana skin merupakan diversifikasi dari limbah pisang yang memiliki potensi untuk menjadi pengganti air kelapa pada pembuatan nata.  Mutu produk nata dipengaruhi oleh banyak faktor, salah satunya adalah sumber nitrogen yang digunakan.  Penelitian ini bertujuan untuk menentukan kombinasi ekstrak tauge dan ZA terbaik.  Penelitian ini dirancang menggunakan rancangan acak kelompok lengkap non faktorial, sebanyak empat ulangan.  Perlakuan yang digunakan yaitu tauge 0 mL dan ZA 6 g (A), tauge 1 mL dan ZA 5 g (B), tauge 2 mL dan ZA 4 g (C), tauge 3 mL dan ZA 3 g (D), tauge 4 mL dan ZA 2 g (E), dan tauge 5 mL dan ZA 1 g (F).  Pengamatan yang dilakukan terdiri dari uji kimia meliputi kadar air, kadar nitrogen, nilai pH, total mikroba, pengukuran rendemen, dan uji sensori yang meliputi warna, tekstur, rasa, dan aroma.  Data yang dihasilkan dianalisis homogenitas dengan uji Bartlett, aditifitas dengan uji Tuckey, dan perbedaan antar perlakuan dengan analisis ragam.  Selanjutnya, data dianalisis dengan uji Beda Nyata Terkecil pada taraf 5%.  Hasil penelitian menunjukkan bahwa perlakuan terbaik nata de banana skin didapatkan pada perlakuan A (tauge 0 mL dan ZA 6 g) dengan warna putih keruh, aroma tidak berbau asam, tekstur kenyal, rasa normal, dengan rata-rata kadar air 94,08%, kadar nitrogen 0,24%, dan kadar rendemen 21,31%.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan karagenan dan glukomanan terhadap karakteristik mi basah subtitusi tepung talas kimpul serta mengetahui proporsi perbandingan karagenan dan glukomanan dengan karakteristik mi basah subtitusi tepung talas kimpul terbaik sesuai SNI 2987-2015. Penelitian disusun dalam Rancangan Acak Kelompok Lengkap (RAKL) dengan 5 kali ulangan. Faktor yang digunakan yaitu formulasi karagenan dengan glukomanan dengan 5 taraf perlakuan yaitu P1 (0%:100%), P2 (25%:75%), P3 (50%:50%), P4 (75%:25%), P5 (100%:0%). Hasil penelitian menunjukkan bahwa penambahan karagenan dan glukomanan berpengaruh terhadap sifat fisik dan sensori mi basah substitusi tepung talas kimpul. Mi basah perlakuan terbaik adalah perlakuan P4 (75% karagenan : 25% glukomanan) dengan nilai kadar air mi mentah 39,07%, kadar air mi matang 68,44%, daya serap air 117,98%, cooking loss 14,12%, skor tekstur (antara kenyal dan agak kenyal), skor warna (antara coklat pudar dan coklat), skor aroma (antara sangat khas talas kimpul dan agak khas talas kimpul), skor penerimaan keseluruhan (suka), kadar protein 3,72%, dan kadar abu tidak larut dalam asam 0,05%.
