ABSTRAKSorghum coklat merupakan biji-bijian yang potensial dikembangkan menjadi tanaman pangan di Indonesia. Kelebihan tanaman ini adalah kemudahannya untuk dibudidayakan dan produktivitas yang tinggi. Namun keterbatasan informasi tentang potensinya, membuat biji sorghum kurang diperhatikan. Tujuan Penelitian ini adalah untuk mendapatkan informasi dasar tentang potensi dan pembatas biji sorghum lokal varietas coklat sebagai tanaman pangan. Penelitian dilakukan dengan menganalisa biji sorghum yang telah disosoh dengan penyosoh beras 4 kali. Hasil penelitian menunjukkan biji sorghum lokal varietas coklat yang didapatkan dari Grati Pasuruan ini cukup berpotensi sebagai tanaman pangan. Biji sosoh mempunyai kadar pati 79,40±4,63% dan protein yang tinggi yaitu 10,62±0,01%, selain itu rendemen sosoh juga tinggi mencapai 77,99±1,39%. Namun demikian, sorghum mengandung senyawa antigizi seperti tanin yang mencapai 8,83±0,05 mg/g, senyawa fitat 1,80±0,47 mg/g dan antitripsin 17,18±2,38 unit/g. Protein sorghum didominasi (71,40±1,29%) oleh kafirin yang memiliki ikatan disulfit tinggi (550,43±4,92 µmol/g). Daya cerna protein sorghum tergolong rendah terlihat dari uji secara in vivo 0,51 atau 51% dan in vitro dengan enzim tripsin sebesar 48,45%. Dimensi biji sorghum dengan rata-rata 3,9±0,7 mm panjang, 3,2±0,2 mm lebar dan 1,8±0,01 mm tebal berbeda dengan biji beras sehingga kurang cocok bila dilakukan penyosohan dengan penyosoh beras. Kandungan senyawa antigizi yang cukup tinggi dan keberadaan ikatan disulfit yang cukup besar serta ditunjang oleh daya cerna protein yang rendah, menunjukkan biji sorghum perlu penanganan lanjutan misalnya dengan proses fermentasi untuk meningkatkan potensinya sebagai bahan pangan. ABSTRACTBrown sorghum is one of cereals with high prospective to be developed as a new source of staple food in Indonesia because it is easily cultivated and has high productivity. However, this grain has been overlooked because of limited available information of its potential used. Aims of this research are to evaluate the sorghum grain to comprehensibly obtain the basic information of its potential and limited factors as staple food. Research results that locally grown brown sorghum grain obtained from Grati, Pasuruan had a high milling yield (77.99±1.39%). The polished grain was composed by 79.40±4.63% starch and 10.62±0.01% protein. It indicated that this sorghum grain was highly prospective to be developed as a staple food. However, the grain also had some restrictive factors such as tannin (8.83±0.05 mg/g), phytic acid (1.80±0.47 mg/g) and anti-trypsin (17.18±2.38 unit/g). The main fraction of protein sorghum grain was Kafirin where this fraction contains a high disulphide bond (550.43±4.92 µmol/g). Bioavailability of protein sorghum evaluated by in vivo and in vitro methods were 51% and 48.45%, respectively. These values could be considered as low digestibility. The sorghum grain had dimension of 3.9±0.7 mm length, 3.2±0.2 mm width and 1.8±0.01 mm thick. Polishing of sorghum grain using rice polished machine c...
This research focuses on the theme of Islamic education reform in Iran, which aims to produce an emancipated and creative generation. The Islamic Republic of Iran has implemented a series of education reforms that prioritize the development of technical and vocational skills, entrepreneurship, interpersonal skills, and the cultivation of students' character and morality. The goal of these programs is to prepare students to face the challenges of the global job market and to advance the Iranian economy. Moreover, the Iranian government has introduced a series of initiatives to promote critical thinking and creativity in its education system. For instance, it has integrated modern technology into its educational system, established research centers and incubators, and encouraged student participation in extracurricular activities. As a result of these reforms, many Iranian students have emerged as successful graduates in various fields, including technology, science, business, and arts. Therefore, this abstract concludes that the Islamic education reform in Iran has been successful in creating a generation of students who are equipped with the skills and knowledge necessary to compete in the global job market and contribute to the advancement of their country's economy. Furthermore, it has also fostered a culture of critical thinking, creativity, and innovation among students, which will be critical to the country's continued progress in the future.
Commercial extruded snacks available in the Indonesian market are generally cereal-based, such as from corn and rice, and there is not any that is from brown sorghum. This research aims to study changes in physical and chemical characteristics of brown sorghum grains after extrusion and compare the extrudate characteristics of products from brown sorghum grains, corn, and rice. Brown sorghum grains are de-husked, ground into grits, and extruded using a single screw extruder at 120°C. The resulting extrudates are then analyzed and compared to rice and corn extrudates. There is a change in chemical content after the sorghum grains are extruded. The content of moisture, fat, starch, and protein decreased, while the content of reducing sugar, ash, and fiber increased. The content of anti-nutritional compounds such as tannins, phytates, kafirin, and disulfide bonds decreased; so that the digestibility value increased from 48.44% (grains) to 75.67% (extrudates). Compared with extrudates from rice and corn, sorghum seed extrudate has the smallest expansion ratio, higher density, darker color, but still has a similar quality in texture.
