Abstract

Black rice and black rice flour is a food product which is very beneficial for the body, because it contains antioxidants. Antioxidant contained in black rice and black rice flour analyzed by examining the antioxidant activity. The purpose of this study is to determine changes to the antioxidant activity of black rice and black rice flour. The research method is using experimental with 2 samples (black rice and black rice flour). In the Data analysis is using independent t test. The results indicate that there are the differences between the antioxidant activity of black rice and black rice flour. It can be concluded that the drying process in the manufacture of black rice flour lowered antioxidant activity in black rice  products.

Abstract

Tujuan dari penelitian ini adalah: memanfaatkan limbah kulit pisang menjadi salah satu produk pangan tinggi kalsium yaitu berupa donat dan mengetahui formulasi tepung terigu : kulit pisang yang tepat sehingga menghasilkan donat tinggi kalsium yang memiliki sifat organoleptik (rasa, keempukan dan warna) disukai .Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 1 faktor yaitu formulasi tepung terigu : kulit pisang dimana masing-masing perlakuan diulang 9 kali. Perlakuannya adalah : K1 =  30%  :  30%; K2 =  40%  :  20% dan K3 = 50%  :  10%.Hasil penelitian menunjukkan bahwa perlakuan terbaik yaitu pada perlakuan formulasi tepung terigu : kulit pisang = 40% : 20%  yang menghasilkan nilai produk tertinggi yaitu sebesar 0,839. Adapun kandungan gizi donat kulit pisang (tiap 100 g bahan) yang paling disukai yaitu protein 18,56 g, karbohidrat 86,19 g dan kalsium 945,3 mg. Berdasarkan hal tersebut di atas maka donat dengan penambahan kulit pisang mempunyai banyak manfaat, diantaranya untuk menekan biaya produksi, mengurangi limbah kulit pisang, meningkatkan intake kalsium, dan yang pasti menyehatkan tubuh. Kandungan gizi yang terdapat dalam donat dengan menggunakan campuran kulit pisang lebih tinggi dibandingkan dengan donat pada umumnya,. Kata kunci : kulit pisang, donat, kalsiumTujuan dari penelitian ini adalah: memanfaatkan limbah kulit pisang menjadi salah satu produk pangan tinggi kalsium yaitu berupa donat dan mengetahui formulasi tepung terigu : kulit pisang yang tepat sehingga menghasilkan donat tinggi kalsium yang memiliki sifat organoleptik (rasa, keempukan dan warna) disukai .Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 1 faktor yaitu formulasi tepung terigu : kulit pisang dimana masing-masing perlakuan diulang 9 kali.

Abstract

The number of female workers has been on the rise along with life necessities. The usual role of women to cook for the family gradually transforms into preparing for customers on street foods. Penyetan is one of the favourite kind of street foods due to its availability and extensive selection of side dish options. The plate is standard dishware used to serve penyetan. One plate typically used to serve many customers one after another with the washing process in between. This research serves the purpose of finding out the hygiene of the street foods in Tambaksari, Surabaya, using the presence of Escherichia coli bacteria as a marker towards 76 penyetan street foods in Tambaksari district. From 76 places, the result showed that only eight places (11%) meet the requirements of the Health Minister Regulation No. 1096/2011 about Hygiene Sanitation for Catering Services, while the other 68 plates (89%) contained bacteria that surpass the threshold of the regulation. And for E. coli, the result was 20% (15 places) are positive, while the other is negative (80% or 61 places).The number of female workers has been on the rise along with life necessities.

Abstract

Meat floss is usually made from animal meat. However, recently meatless floss made from vegetables of fruit rinds is gaining popularity. The use of breadfruit is less than optimum, thus processing it to be meatless fruit can increase its value. On the other hand, jackfruit rind has unique characteristics which make it suitable to be processed into meatless floss. This research employed the Completely Randomised Factorial Design treatment. The first factor was two boiling times, namely 8 minutes and 10 minutes. The second factor was the combination ratio of jackfruit rind and breadfruit, namely 25% : 75%; 50% : 50 %; and 75% : 25%. Each treatment was repeated three times. The result indicated that boiling time has a significant influence on the chemical quality of meatless floss, including water and rind content. On the other hand, the ratio of jackfruit rind and breadfruit has significantly affect ash and fat content. Meanwhile, the combination of boiling time and ratio of jackfruit rind and breadfruit significantly affect ash content. The result if Wallis Kruskal test for the organoleptic quality of meatless floss revealed that the boiling time and ratio of jackfruit rind and breadfruit significantly affect colour and crunch, and did not affect flavour and aroma. The L2P2 treatment code, namely 10 minutes boiling time and the ratio 50 %: 50% ratio of jackfruit rind and breadfruit, was the best treatment in this study. This treatment obtained the highest score of 0,68, with water 4,992% content; 6,81% rind content, 5,5 in flavour; 11,563% fat content; 4,9 in colour; 5,1 in aroma; 5,6 in crunch; and 7,937% ash content.
