    (2013-02-05) Yenni
    The research was conducted in August to September 2012 at the Laboratory of Fish Processing Technology, Food Chemistry and Food Microbiology and Biotechnology Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this research was to investigate the effect of addition of fish protein concentrate on quality of instant sago noodle during room temperature storage. Sago noodle was prepared from sago flour; and fish protein concentrate (0%, 5%, 10% and 15%) was added to fortify quality characteristic of the noodle. The noodle was evaluated for sensory quality, moisture, protein, fiber, dehydration capacity, peroxide value, and total plate count every 0, 15, 30 and 45 days. The result indicated that the instant sago noodle fortified with 15% fish protein concentrate was the best quality product. Moisture, protein and fiber composition of the product at the end of 45 days storage was 12.02%, 3,73%, and 19,50% respectively. Dehydration capacity, peroxide value and total plate count of the product at the end of 45 day storage was 48,02%, 25,61 meq/1000 gram sample, and 4,20 bacteri/gram respecively.

    UJI PEMBENTUKAN BIOGAS DARI SAMPAH PASAR DENGAN PENAMBAHAN KOTORAN AYAM
    (2014-06-30) Dewilda, Yommi; Yenni; Kartika, Dila
    Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh penambahan kotoran ayam dalam pembentukan biogas dari sampah pasar (sayur dan buah) tanpa pengkondisian lingkungan digester. Metode yang digunakan adalah anaerobic batch digester skala laboratorium 50 liter. Penentuan komposisi gas CH4 dan CO2 melalui metode absorbsi dengan menggunakan absorban alkohol sedangkan komposisi gas CO2 menggunakan absorban NaOH. Penelitian dilakukan selama 30 hari. Digester terdiri dari digester kontrol dan digester uji. Digester kontrol diisi dengan sampah sayur dan buah (C/N=37,6087; kadar air=55,3790%) dan penambahan air. Digester uji diisi dengan campuran sampah sayur dan buah, kotoran ayam (C/N=6,6320; kadar air 65,7653%) dan penambahan air. Digester kontrol dan uji diisi sebanyak 30 liter. Setelah pengamatan 30 hari, maka didapat produksi kumulatif biogas rata-rata adalah 21,20 liter (digester kontrol) dan 22,67 liter (digester uji). Komposisi rata-rata gas CH4 dan CO2 pada pengujian hari ke-16 adalah 5,5787% dan 1,5031% (digester kontrol), 10,7181% dan 1,7516% (digester uji). Komposisi rata-rata gas CH4 dan CO2 pada pengujian ke-30 adalah 11,2669% dan 2,5941% (digester kontrol), 25,1390% dan 3,0886% (digester uji). Penambahan kotoran ayam tidak memberikan pengaruh yang signifikan terhadap pembentukan biogas.
