Abstract

The objective of the research was to find out the optimum alkaline treatment to produce a light colour, starch-rich flour containing high levels of undamaged starch, intended for the making of a formulated biscuit. The research was divided into two experiments. First, a factorial randomized block design experiment with two factors: the concentration of NaOH (0.04%, 0.06%, and 0.08%) and the dipping time (15, 30 and 45 minutes). The second experiment was the use of the Linear Programming approach supported by the QSB to obtain the desirable biscuit formula. The results of the first experiment indicated that the breadfruit flour dipped for 45 minutes in the 0.08% NaOH solution was the best one. The treated flour at a moisture content of 6.63% contains 60.86% starch, 22.56% amylose, 3.25% protein, 6.26% fat, and the L value (degree of Lightness) of 74.9, water absorption index of 4.80 g/g, initiation of gelatinization temperature of 69.3 oC, gelatinization temperature of 80.9 oC, maximum viscosity of more than 2000 AU and undamaged granules. The best results of the second experiment was the biscuit formula containinq  31.76% breadfruit flour, 20% wheat flour, 13.03% red bean flour, which  meets  with  the  nutrition  requirement. The  texture  and  breaking force of the formulated biscuit was not significantly difference with the one of the biscuit made without the addition of breadfruit flour (the control), but has the lower L value. Moreover except  the crispness, the colour, aroma and the taste of formulated biscuit were found the best significantly different from those of the control biscuit. Keywords: Breadfruit flour, Alkaline modification (NaOH), biscuit, Linier Programming formulation

Abstract

Upaya untuk memecahkan masalah kerawanan pangan dan energi perlu segera dilakukan. Salah satu alternatif adalah mencari bahan baku yang dapat dimanfaatkan secara keseluruhan termasuk bagian-bagian yang selama ini dianggap sebagai limbah. Tanaman jagung (Zea mays) adalah komoditas pertanian yang sebenarnya punya prospek untuk dikembangkan produk-produknya secara luas, diikuti dengan upaya pemanfaatnya untuk menghasilkan produk olahan multiguna dengan bahan baku dari tangkai, daun, pelepah, biji jagung pipilannya serta bonggolnya. Rekayasa teknologi yang efektif dan efisien dapat diterapkan untuk menghasilkan produk pangan berbentuk ekstrudat termodifikasi dengan ubi jalar dan kedelai, pati jagung, dekstrose, sirup jagung, protein (gluten) dan minyak jagung. Tongkol jagung, disamping digunakan sebagai pakan ternak dapat juga dimanfaatkan untuk bahan baku sumber energi terbarukan antara lain bioetanol dan briket arang. Kulit jagung dapat diolah menjadi "soluble sugars". Batang jagung telah digunakan untuk bahan baku kertas. Selanjutnya dengan menggunakan mikroorganisme, daun jagung dapat diubah menjadi pakan ternak berprotein tinggi. Demikian juga jerami jagung dapat dimanfaatkan untuk pupuk organik atau kompos. Kebijakan pengembangan pertanian untuk komoditas jagung perlu didukung berbagai pihak terkait yaitu pengambil kebijakan, pengusaha dan petani, serta para peneliti, sehingga produksi produk multiguna berbasis jagung dapat lebih efektif dan efisien.

Abstract

Susu merupakan media pertumbuhan yang sangat baik bagi bakteri dan dapat menjadi sarana potensial bagi penyebaran bakteri patogen dan bakteri pembusuk yang mudah tercemar ketika penanganannya tidak memperhatikan kebersihan. Pendinginan susu bertujuan agar terjadi penurunan suhu untuk menahan mikroba perusak agar tidak berkembang, sehingga susu tidak mengalami kerusakan dalam waktu yang relatif singkat. Suhu rendah untuk pengangkutan susu segar tergantung juga pada waktu pengangkutan karena tidak semua waktu pengangkutan membutuhkan suhu pengangkutan yang sangat rendah, jadi perlu diketahui berapakah kombinasi suhu dan waktu pengangkutan yang tepat yang layak secara teknis dan finansial. Hasil penelitian menunjukkan suhu dan lama waktu pendinginan berpengaruh nyata terhadap total bakteri susu segar dan berpengaruh nyata terhadap kadar protein. Suhu rendah yang tepat untuk pengangkutan susu segar adalah 10 oC untuk masing masing waktu pengangkutan susu segar (30, 60, dan 90 menit). Hasil perhitungan finansial didapatkan HPP sebesar Rp 3802,45, BEP selama 211 hari kerja. Nilai R/C ratio sebesar 1.05, total modal sebesar Rp 3422202,510 dan menghasilkan pendapatan sebesar Rp 3600000000 sehingga dalam satu tahun perusahaan akan mendapatkan keuntungan sebesar Rp 177797490
