<p>Beras analog dari tepung jagung perlu penambahan tepung kacang merah untuk meningkatkan nilai gizinya, terutama protein. Penambahan bahan pengikat berupa agar-agar diperlukan untuk menghasilkan karakter beras analog yang kompak. Penelitian ini bertujuan untuk 1) menentukan formula yang tepat dalam pembuatan beras analog dari tepung jagung dan tepung kacang merah dengan penambahan agar-agar; 2) mempelajari sifat fisik, kimia dan sensoris beras analog terbaik dan membandingkan dengan beras sosoh. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor yang diteliti, yaitu proporsi tepung jagung:kacang merah (90:10; 85:15; 80:20; 75:25 dan 70:30), dan penambahan agar-agar (0,5; 1; 1,5 dan 2 %). Variabel yang diamati pada beras analog meliputi rendemen, koefisien rehidrasi, penyerapan air, densitas kamba, kadar air, kadar protein, kadar lemak, kadar karbohidrat dan uji sensori (warna, aroma, tekstur, flavor dan kesukaan). Formula beras analog terbaik yang diperoleh adalah yang terbuat dari tepung jagung:tepung kacang merah dengan perbandingan 70:30 dan penambahan agar-agar 1,5%. Beras analog tersebut memiliki kadar protein 13,44%, kadar lemak 0,941%, kadar air 5,15%, kadar karbohidrat 78,95%, koefisien rehidrasi 3,73 dan densitas Kamba 0,517 g/ml. Beras IR 64 lebih mempunyai keunggulan dari aspek warna, flavor, dan aroma, tetapi kesukaan panelis terhadap beras analog dan beras IR64 tidak berbeda. Dengan demikian beras analog ini dapat digunakan sebagai salah satu pilihan pangan pokok dengan sifat fisik, kimia dan sensori tidak berbeda dengan beras IR64.</p><p>To increase the nutritional value of analog rice from corn flour, especially in increasing protein levels, it is necessary to add a protein source, namely red bean flour. The addition of agars as binder is needed to form a compact analog rice character. The purpose of the study are 1) to determine the right formula in making analog rice from corn flour and red bean flour with the addition of gelatin; 2) to study the physical, chemical and sensory properties of the best analog rice and comparing it with parboiled rice. The study used a factorial Completely Randomized Design (CRD) with 2 factors, namely the proportion of corn flour:red beans (90:10; 85:15; 80:20; 75:25 and 70:30), and the addition of agar (0.5; 1; 1.5 and 2%). Variables observed in analog rice include yield, rehydration coefficient, water absorption, density, moisture content, protein content, fat content, carbohydrate content and sensory test (color, aroma, texture, flavor and preference). The best analog rice formula is made from corn flour: red bean flour with a ratio of 70:30 and 1.5% added agar. The analog rice has a protein content of 13.44%, fat content of 0.941%, moisture content of 5.15%, carbohydrate content of 78.95%, rehydration coefficient of 3.73 and bulk density of 0.517 g/ml. IR 64 rice has more advantages in terms of color, flavor and aroma, but texture and the panelists' preference for analog rice and IR64 rice is no different. Thus this analog rice can be used to substitute rice for physical, chemical and sensory properties no different with IR64 rice.</p>
<p class="Abstrak"><span lang="EN-GB">Hanjeli adalah salah satu tanaman potensial untuk diversifikasi pangan. Karbohidrat dan pati dalam biji hanjeli mirip dengan sereal lainnya seperti gandum, sorgum, jagung. Produk olahan sereal salah satunya adalah berondong yang diperoleh dengan metode <em>puffing</em>. <em>Puffing</em> adalah proses pengolahan pangan yang menyebabkan perubahan struktur sehingga terjadi penggembungan atau perluasan volume akibat pengaruh suhu dan tekanan. Pada penelitian ini dilakukan proses <em>puffing</em> pada biji hanjeli menggunakan microwave dengan perlakuan A (Tingkat Energi) dan B (Waktu proses) dengan 3 kali ulangan. Hasil penelitian menunjukkan bahwa energi gelombang mikro yang digunakan dalam proses pengujian popping hanjeli memiliki dampak nyata dengan nilai signifikan <0,05 terhadap kadar air, lemak, karbohidrat. pengujian konten dan organoleptik pada parameter warna dan tekstur dengan tingkat energi sedang. Perlakuan terbaik yang dilakukan pada penelitian ini merupakan produk berondong hanjeli dengan tingkat energi medium dan waktu proses 2,5 menit. Berondong hanjeli tersebut memiliki hasil analisa fisik pada densitas kamba 0,30 %. Berondong hanjeli memiliki hasil analisa kimia pada kadar air 3,59%, kadar abu 0,13%, kadar protein 14,60%, kadar lemak 1,14%, kadar karbohidrat 80,54%, kadar amilosa 11,09%, kadar amilopektin 60,22%.</span></p><p class="Abstrak"> </p><p class="Abstrak"><strong><span lang="EN-GB">Physicochemical Properties Of Popping Hanjeli (</span></strong><strong><em><span lang="EN-GB">Coix Lacryma-Jobi L</span></em><span lang="EN-GB">)</span></strong></p><p class="Abstrak">Utilitization of Hanjeli plant has not been done yet because of society’s lack of knowledge. The carbohydrate and starch in Hanjeli seeds are similar to other cereals’ content such as wheat, sorghum, corn and barley. The brunch cereal is the result of <em>puffing</em> process. In this research, the <em>puffing</em> process was done by using the microwave. One of the benefits of this research is to ascertain of <em>puffing</em> process by using the microwave towards Hanjeli seeds. This research used the experimental method with two factors of Completely Randomized Factorial Design (CRFD) which consists of factor A (Power Level) and factor B (Time process) with three times repetition. Analytical techniques that were used were variance or Analysis of Variance (ANOVA) and continued to Post-Hoc Test with Tukey’s test method. Analysis of physical properties which was conducted is bulk density. Analysis of chemical properties which was conducted are water, ash, protein, fat, carbohydrate, amylose and amylopectin. Organoleptic analysis which was conducted are acceptance test (hedonic) and hedonic quality test. Based on the research result of change in the physicochemical properties, the microwave energy which was used in the <em>puffing</em> process to test the popping hanjeli has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality on the tests of water, fat, carbohydrate content and organoleptic testing on color and texture parameters with medium energy levels. Time usage of popping hanjeli using the microwave has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality on the tests of water, fat, carbohydrate content and organoleptic testing on color and texture parameters with medium energy level. There is a different interaction between the energy level and time process, it has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality which at the medium energy level with a time process of 2,5 minutes.</p>
<p>CATA merupakan metode sederhana dan cepat untuk mengumpulkan informasi mengenai sifat sensori suatu produk berdasarkan persepsi konsumen. Penelitian ini bertujuan untuk (1) mempelajari profil sensori sampel es krim ideal menurut panelis, (2) mengidentifikasi peta kesukaan panelis terhadap sampel es krim, (3) mengidentifikasi atribut sensori yang berpotensial dalam pengembangan produk es krim. Hasil analisis CATA dengan perangkat lunak XLSTAT 2016 menunjukkan bahwa persepsi es krim ideal memiliki atribut sensori dominan, yaitu <em>sweetness</em>, <em>softness</em>, <em>spoondability</em>, dan <em>homogenity</em>. Sampel F9 mendekati produk es krim ideal menurut panelis karena memiliki nilai atribut sensori es krim ideal yang lebih tinggi dibandingkan dengan sampel lain. Analisis atribut sensori berdasarkan metode <em>penalty analysis</em><em> </em>diperoleh bahwa atribut <em>must have </em>adalah <em>sweetness, softness, skim milk powder, homogenity, coconut flavor</em>, dan <em>spoondability</em>, atribut <em>nice to have </em>adalah <em>iciness, sweet aftertaste, bitter aftertaste, greasiness, </em>dan <em>mouth coating</em>, dan atribut <em>must not have </em>adalah <em>thickness</em>. Tidak ada atribut sensori pada sampel es krim yang benar-benar mengendalikan kesukaan panelis atau tidak ada atribut sensori yang secara signifikan berperan dalam meningkatkan atau menurunkan kesukaan panelis.</p>
