This research aims to increase flour whiteness index to foot elephant yam (Amorphophallus paeoniifolius) flour along the production process. The chemical agents used in this research were sodium metabisulfite (Na2S2O5) and ethanol. The corms were treated by soakeing in sodium metabisulfite 4% (w/v) for 3 hours, adding with ethanol 96% at a ratio of 1:2 and then blended with a speed of about 12,000 rpm for 5 minutes then filtered, and blanching into sodium metabisulfite 4% (w/v) for 3 minutes. The result showed that using  Na2S2O5 4% (w/v) as a chemical agent on the initial production of Amorphophallus paeoniifolius flour was able to produce flour with the highest whiteness index. Therefore, this method will produce Amorphophallus paeoniifolius flour more applicable for the diversity of the food industry, especially noodles, biscuits, and bakery.

ABSTRACT This study aimed to determine the effect of oci fermentation time on total microbes, total lactic acid bacteria, water content, protein content, and pH value. The oci fish used are fresh oci fish from the fish market in Gorontalo, then fermented for 0, 3, 10 and 15 days. The research method used the experimental method through a complete randomized design pattern using variance analysis followed by the Duncan test. For 15 days fermented, the pH value, water content and microbial total decreased, but the protein content and the number of lactic acid bacteria increased. The bakasang of oci at the end of fermentation has a total lactic acid bacteria of 2.51x107 CFU/g, the water content of 65.56%, the protein content of 5.98%, and pH value of 6.0. Keywords: oci fish, fermentation, bakasang, lactic acid bacteria   ABSTRAK Tujuan penelitian ini adalah untuk menganalisa sifat kimia dan mikrobiologi bakasang ikan oci dengan lama fermentasi yang berbeda. Ikan oci yang digunakan adalah ikan oci segar dari pasar ikan di Gorontalo, lalu difermentasi selama 3, 10 dan 15 hari. Parameter pengamatannya meliputi sifat kimia yang terdiri dari kadar air, kadar protein, nilai pH. Sedangkan sifat mikrobiologi yang diamati yaitu total mikroba dan total bakteri asam laktat. Metode penelitian ini menggunakan rancangan acak lengkap dan analisis sidik ragam dilanjutkan dengan uji Duncan. Selama 15 hari difermentasi, nilai pH, kadar air dan total mikroba menurun, namun kadar protein dan jumlah bakteri asam laktat mengalami peningkatan. Bakasang ikan oci pada akhir fermentasi mempunyai total bakteri asam laktat 2,51x107 cfu/g, kadar air 65,56%, kadar protein 5,98%, dan nilai pH 6,0. Kata kunci: ikan oci, fermentasi, bakasang, bakteri asam laktat

Nutrizinc rice is a biofortified variety designed with the advantage of high specific nutritional value, especially at higher levels of zinc nutrition compared to Ciherang rice. The mineral zinc is useful for preventing stunting in humans, and to help protect the human immune system from the attack of the COVID-19 virus. However, this variety has just been promoted by The Assessment Institute for Agricultural Technology (AIAT, in Indonesian: Balai Pengkajian Teknologi Pertanian, BPTP) Gorontalo Province so people are still not familiar with this rice. Therefore, it is important to conduct research related to the analysis of the level of consumer acceptance aimed at knowing consumer preferences and attitudes towards the attributes of high-zinc nutritious rice. The study had 60 respondents who were chosen by chance (accidental). This study used Chi Square analysis (X2) to see the differences in consumer preferences for the attributes of high zinc nutritional rice with various cooking methods and the ratio between rice and water. Meanwhile, Fishbein Multi-attribute analysis was used to determine consumer attitudes towards the attributes of high-zinc nutritional rice. The results showed that the different methods of cooking and adding water to the rice did not significantly change the flavor, color, and aroma of the rice, on the contrary, it only changed the texture of the rice. The high-zinc nutritional rice that consumers like was rice that had a slightly sweet flavor, fluffier texture, bright white color, and has no odor. In addition, the color and texture attributes of rice with high zinc nutrition were the most dominant considerations compared to other attributes in deciding to buy or consume rice with high zinc nutrition.

Puree ikan oci (Rastrelliger kanagurta) merupakan pengembangan produk olahan ikan oci yang ditambahkan bahan pengikat berupa tepung terigu, tepung tapioka, dan gelatin ikan. Tujuan dari penelitian ini adalah untuk mengetahui tingkat penerimaan produk puree ikan oci. Penelitian ini menggunakan rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan dengan formulasi daging ikan oci, tepung terigu, tepung tapioka dan gelatin ikan sebagai perlakuan yaitu (300 g,150 g, 150 g) dan gelatin ikan (0 g, 10 g, 15 g, dan 20 g). Hasil penelitian menunjukkan perlakuan yang paling disukai panelis adalah P3 dengan gelatin ikan 20 g. Dari kadar protein, yang paling tinggi adalah perlakuan P3 dengan nilai 16,29 %.

Ilabulo merupakan salah satu makanan tradisional di Provinsi Gorontalo. Bahan dasar dalam pembuatan ilabulo adalah tepung sagu, dan biasanya ditambahkan ampela ayam dan bumbu-bumbu. Penelitian ini bertujuan untuk mengetahui formulasi substitusi tepung kacang hijau dan tepung sagu yang terbaik pada pembuatan ilabulo, serta menentukan kadar air, kadar abu dan kadar protein dari ilabulo yang diperoleh pada formulasi terbaik. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan 6 perlakuan A: tepung kacang hijau 15%, tepung sagu 85%, B: tepung kacang hijau 30%, tepung sagu 70%, C: tepung kacang hijau 50%, tepung sagu 50%, D: tepung kacang hijau 65%, tepung sagu 35%, E: tepung kacang hijau 75%, tepung sagu 25%, F: tepung kacang hijau 0%, tepung sagu 100%. Tahap pertama pada penelitian ini adalah menentukan formulasi substitusi tepung kacang hijau dan tepung sagu pada pembuatan ilabulo. Penentuan formulasi terbaik berdasarkan penilaian uji organoleptik oleh 25 orang panelis. Tahap kedua adalah menganalisis kadar air, kadar abu dan kadar protein perlakuan kontrol dan satu perlakuan substitusi tepung kacang hijau dan tepung sagu pada tahap sebelumnya. Hasil penelitian menunjukkan berdasarkan uji organoleptik semakin besar penambahan tepung kacang hijau semakin berkurang tingkat kesukaan panelis terhadap uji organoleptik aroma, warna, tekstur dan rasa. Namun demikian, jika dibandingkan dengan perlakuan penambahan tepung kacang hijau lainnya, penambahan tepung kacang hijau dapat sebanyak 15% lebih disukai oleh panelis. Kadar air, kadar abu dan kadar protein ilabulo dengan penambahan tepung kacang hijau 15% berturut-turut adalah 46,45%, 3,5%, dan 11%.
