PENGARUH RASIO TEPUNG UDANG REBON (Acetes sp.) DAN TEPUNG TAPIOKA TERHADAP KARAKTERISTIK SENSORI, FISIK DAN KIMIA KERUPUK (22t201)

ABSTRAK Firman Multazam. 26030115120028. Pengaruh Rasio Tepung Udang Rebon (Acetes sp.) dan Tepung Tapioka terhadap Karakteristik Sensori, Fisik dan Kimia Kerupuk (Retno Ayu Kurniasih dan Apri Dwi Anggo) Pengawetan udang rebon dapat diolah menjadi berbagai produk pangan seperti abon, kerupuk udang, dan tepung udang. Kerupuk udang mempunyai beberapa kualitas bergantung pada komposisi banyaknya udang yang terkandung dalam kerupuk. Tujuan penelitian ini adalah mengetahui pengaruh perbandingan tepung udang rebon dan tepung tapioka terhadap karakteristik sensori, fisik dan kimia kerupuk udang serta mengetahui formulasi terbaik pada pembuatan kerupuk udang rebon. Desain percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan rasio tepung udang rebon dan tepung tapioka, yaitu 0:7, 1:6, 2:5, 3:4 dan 4:3 dengan tiga kali ulangan. Parameter uji meliputi sensori, kerenyahan, daya kemekaran linier, kadar air, kadar abu, kadar lemak, kadar protein dan kadar karbohidrat. Data nonparametrik dianalisis dengan KruskalWallis dan uji lanjut Mann-Whitney. Data parametrik dianalisis menggunakan ANOVA dan uji lanjut Tukey HSD. Hasil penelitian menunjukkan bahwa semakin banyak tepung udang rebon dan semakin sedikit tepung tapioka yang digunakan menyebabkan peningkatan nilai kadar abu, kadar lemak, kadar protein dan penurunan nilai sensori, kerenyahan, daya kemekaran linier, kadar air, kadar karbohidrat pada kerupuk udang rebon. Rasio tepung udang rebon dan tepung tapioka yang terbaik adalah 1:6 berdasarkan nilai sensori tertinggi, yaitu 7,96<µ<8,14. Kerupuk yang dihasilkan dalam penelitian ini memiliki nilai kerenyahan 787,21 s.d. 1188,70 gf, daya kemekaran linier 39.73 s.d. 319.29%, kadar air 9,93 s.d. 11,27 %, kadar abu 4,04 s.d. 12,47%, kadar lemak 0,39 s.d. 1,30%, kadar protein 0,41 s.d. 37,10%, dan kadar karbohidrat 43,59 s.d. 84,55%. Komparasi dengan kerupuk udang menurut SNI No. (8272:2016) bahwa kerupuk udang rebon termasuk grade I dengan kadar protein yaitu 8,03 s.d. 32,98%.

The Effect of Ratio of Rebon Shrimp Flour (Acetes sp.) and Tapioca Flour to the Sensory, Physical and Chemical Characteristics of Crackers (Retno Ayu Kurniasih dan Apri Dwi Anggo) Preservation of rebon shrimp can be made into many food products, for instance, floss, shrimp crackers, and shrimp flour. Shrimp crackers have several qualities depending on the composition of the amount of shrimp contained in the crackers. The purpose of this study was to determine the effect of the ratio of rebon shrimp flour and tapioca flour on the sensory, physical and chemical characteristics of shrimp crackers and to determine the best formulation for making rebon shrimp crackers. The research design used a completely randomized design (CRD) with substitution treatment of rebon shrimp flour and tapioca flour, that were 0:7, 1:6, 2:5, 3:4 and 4:3 with three replications. The test parameters included sensory, cripness, linear bloom power, water content, ash content, fat content, protein content, and carbohydrate content. Nonparametric data were analyzed by Kruskal-Wallis and Mann-Whitney follow-up tests. Parametric data were analyzed using ANOVA and Tukey HSD follow-up tests. The results showed that the use of more rebon shrimp flour and less tapioca flour would increase the value of the ash content, fat content and protein content in rebon shrimp crackers, and it would also decrease the value of sensory, cripness , linear bloom power, water content, carbohydrate content in it. The best ratio of rebon shrimp flour and tapioca flour was 1:6 according to the highest sensory value, which was 7.96 < μ < 8.14. The crackers as a result of this research had cripness 787.21 to 1188.70 gf, linear bloom power 39.73 to 319.29 %, water content 9.93 to 11.27 %, ash content 4.04 to 12.47%, lipid content 0.39 to 1.30%, protein content 0.41 to 37.10%, and carbohydrate content 43.59 to 84.55%. Comparison with shrimp crackers according to SNI No. (8272:2016) was that rebon shrimp crackers were grade I with a protein content of 8.03 to 32.98%.
