This research aimed to know the educational strategy value in constructing the students’ religious character. This research used descriptive analytic that used the scholars’ theories about the value of education in constructing  of character building. As for the researcher conducted analysis in roder to know the effectiveness of educational strategy value which is considered ineducation world. The finding of this research concluded that the educational strategy value  can use several strategies, that are moral knowing, modeling and moral modeling, feeling and loving the good, moral acting, punihsment, admonition, and habituation. As for the success of constructing the students’ character is when the people has multi-competence as well as the science of moral knowing, moral feeling and moral action as a the entity which is can not be separated.

The disadvantageous properties of sago starch has limited its application in food and industrial processes. The properties of sago starch can be improved by changing its physicochemical and rheological characteristics. This study examined the influence of reaction time, acidity, and starch concentration on the oxidation of sago starch with ozone, a strong oxidant. Swelling, solubility, carbonyl, carboxyl, granule morphology, thermal profile, and functional groups are comprehensively observed parameters. With starch concentrations of 10–30% (v/w) and more prolonged oxidation, sago starch was most soluble at pH 10. The swelling power decreased with a longer reaction time, reaching the lowest pH 10. In contrast, the carbonyl and carboxyl content exhibited the same pattern as solubility. A more alkaline environment tended to create modified starch with more favorable properties. Over time, oxidation shows more significant characteristics, indicating a superb product of this reaction. At the starch concentration of 20%, modified sago starch with the most favorable properties was created. When compared to modified starch, native starch is generally shaped in a more oval and irregular manner. Additionally, native starch and modified starch had similar spectral patterns and identical X-ray diffraction patterns. Meanwhile, oxidized starch had different gelatinization and retrogradation temperatures to those of the native starch.

Beras analog merupakan beras tiruan yang terbuat dari bahan-bahan seperti umbi-umbian dan serealia. Ubi ungu (Ipomea batatas) adalah salah satu potensi lokal pangan yang layak dikembangkan sebagai bahan baku beras analog. Penelitian ini bertujuan untuk mengkaji pengaruh perbandingan komposisi tepung pati ubi ungu terhadap nilai gizi, sifat fisikokimia, sifat hedonik beras analog dibandingkan dengan beras padi, serta menentukan komposisi bahan baku terbaik dari beras analog ubi ungu. Penelitian ini terdiri dari 3 tahapan utama, yaitu tahap pembuatan tepung dan pati ubi ungu, tahap fortifikasi yang dilakukan bersamaan dengan proses pembuatan beras analog, serta tahap analisis hasil. Penelitian ini menggunakan variasi komposisi tepung dan pati ubi ungu sebesar 100:0 (A); 90:10 (B); 80:20 (C); 70:30 (D); 60:40 (E) dengan basis 100 gram. Beras Delangu digunakan sebagai variabel kontrol dalam penelitian ini. Hasil penelitian menunjukkan bahwa semakin tinggi komposisi pati dalam beras analog ubi ungu, maka kandungan amilosa meningkat, tekstur beras semakin keras dan tidak mudah rapuh, daya rehidrasi tinggi, dan densitas kamba rendah. Beras analog dengan komposisi 80% tepung dan 20% pati (kode C) merupakan produk yang paling disukai oleh panelis. Produk ini memiliki rasa, tekstur, dan kenampakan yang menyerupai beras pada umumnya. Beras analog kode C kaya akan kandungan protein 6,7337%, kadar amilosa 15,56%, nilai densitas kamba 0,638 g/ml dan daya rehidrasi sebesar 1,5 ml/g. Nilai gizi, sifat fisikokimia dan sifat hedonik beras analog memiliki karakteristik yang menyerupai beras Delangu. Berdasarkan beberapa parameter, beras analog memiliki keunggulan dibandingkan beras Delangu. Kata kunci: beras analog, ubi ungu, tepung ubi ungu, pati ubi ungu, sifat fisikokimia

This work investigated the physicochemical properties of glucomannan-alginate combination as an excipient of vitamin C encapsulation. The effects of glucomannan-alginate ratio, concentration of vitamin C and preparation method on the encapsulation physicochemical properties were studied. Swelling and solubility of the vitamin C encapsulation were determined in 2 pH conditions which mimic the environment pH of the stomach and the lower gastrointestinal tract. The ratio of glucomannan-alginate on swelling at both pHs had a similar impact on the solubility. Higher values of swelling and solubility were observed at pH 6.8 than those at pH 1.2. The second method preparation of 1:1 (w/w) ratio of glucomannan-alginate showed the most soluble excipient in pH 6.8. The highest viscosity was observed at encapsulation of 3% vitamin C prepared using the second method of 3:1 (w/w) of glucomannan-alginate.

Demineralization is required to reduce the ash content of gelatin. Previous studies have confirmed the high quality of gelatin was produced after demineralized using combination of NaCl and aqueous NaOH. The purpose of this study was to determine the effect of NaCl on the properties of gelatin from Lizardfish (Saurida spp.) scales. The cleaned scales was demineralized using a mixture of NaOH 0.5% and NaCl (0-0.8%), at various temperatures (45, 65, 86oC) and time (30, 60, 90 and 150 minutes). The obtained samples was determined by ash content, pH, the lightness and moisture content. Addition of NaCl reduced the ash, pH and moisture content but increased the whiteness. Gelatin physical properties increased inline with NaCl concentration. Extended demineralized period gave a positive effect on ash, pH and moisture content but opposite effect was observed in the lightness and physical properties. Extended demineralization periods in high temperature reduced gelatin quality. The highest gel strength was found at demineralization for 150 min at 65oC using a combination of NaOH 0.5% and NaCl 0.8%. At this condition, the gelatin has 10%, 1,7%, 248 bloom, and 7,1 cP of moisture content, ash, gel strength and viscosity, respectively, which fulfil SNI 06.3735.1995.
