Abstract


Oyek or dried growol was traditional food from Kulonprogo Yogyakarta that was made of cassava through spontaneous fermentation by soaking in water. After that, the cassava was formed, steamed, and dried. Oyek could be utilized as main food for substituting rice, but the protein of oyek was lower than rice. This research was conducted to determine the best treatment of oyek based on the preference of the oyek that were made of variation of germinated and ungerminated cowpeas flour addition (oyek treatment). This research was also to determine the proximate composition especially the increase of protein and lactic acid bacteria of the best treatment of oyek compared with oyek without cowpeas addition (control). The result of this research showed that the 30% flour of cowpeas sprout as source of protein could be added in the best oyek without altering its overall preference. The result of this research showed the chemical  composition of the best oyek compared to oyek control were significant different, esspecially protein. The protein of  the best oyek increased 4.9 times compared to control. The lactic acid bacteria decreased for processing  growol to oyek. The lactic acid bacteria of the best oyek was higher than control, that were 3.10 x 10 1(CFU/g sampel) respectively.

ABSTRAK


Oyek atau growol yang dikeringkan adalah makanan tradisional dari Kulonprogo Yogyakarta yang dibuat dari ubi kayu/ singkong melalui tahap fermentasi secara spontan dengan cara perendaman dalam air, selanjutnya dicetak, dikukus menjadi growol dan dikeringkan. Oyek dapat dimanfaatkan sebagai pangan pokok alternatif pengganti beras, namun kadar proteinnya lebih rendah daripada beras. Penelitian ini bertujuan untuk menentukan oyek perlakuan terbaik yang dibuat dengan variasi penambahan tepung kacang tunggak yang dikecambahkan dan tidak dikecambahkan berdasarkan tingkat kesukaannya. Selain itu, penelitian ini ditujukan untuk menentukan komposisi kimia proksimat khususnya peningkatan kadar protein dan kandungan bakteri asam laktat (BAL) oyek terbaik dengan penambahan kacang tunggak dibandingkan oyek tanpa penambahan kacang tunggak (kontrol). Hasil penelitian menunjukkan bahwa oyek terbaik yang diterima panelis dan tingkat kesukaannya tidak berbeda nyata dengan kontrol yaitu oyek dengan penambahan tepung kacang tunggak yang dikecambahkan sebesar 30%. Kadar protein oyek tersebut meningkat 4,9 kali terhadap kontrol. Kandungan bakteri asam laktat menurun selama pengolahan growol menjadi oyek. Kandungan bakteri asamlaktat oyek tersebut lebih tinggi daripada kontrol yaitu berturut-turut 3,10 x 103 dan 4,0 x 101 (CFU/g sampel).
