The research aims to analyze the chemical and organoleptic properties of sorghum flour fermented by the addition of lactic acid bacteria. The study consisted of three stages, namely the preparation phase for the bacterial starter, the stage of making fermented sorghum flour and the analysis stage. The study consisted of four treatments namely one treatment of sorghum flour which was fermented spontaneously as a control and the other three sorghum flour fermented by the addition of Lactobacillus plantarum lactic acid bacteria, Lactobacillus fermentum and Lactobacillus paracasei. The fermentation process was carried out for 5 days, then the data were analyzed using one-way analysis of variants (ANOVA) at the 95% level with Duncan's further test. The results showed that the addition of lactic acid bacteria had no effect on water content, crude fiber content, tannin content, acidity (pH) value, panelist preference level on color, aroma and texture but had a significant effect on the level of panelist preference on overall sorghum flour resulting from.

The aim of this research is to find out the physical, chemical and organoleptic characteristics of cookies substituted by fermented sorghum flour and to determine the characteristics of the best cookies so that they can be used as alternative products based on local cereals. The study consisted of two stages, namely the manufacture of cookies and analysis. This study uses a completely randomized design with a combination of 50:50 flour and sorghum fermented flour and 100% wheat flour as a control. Data were analyzed using one-way analysis of variants (ANOVA) at 95% level and Duncan's continued test. The results showed that the used of fermentated sorghum flour as a substitute for flour making cookies had a significant effect on color, texture (level of hardness), moisture content and the level of panelist preference on cookie texture, but had no significant effect on protein content and the level of panelist freference on color, aroma, taste, aftertaste and overall of cookies produced.

The study aimed to validate the method of calcium content analysis in fresh milk by complexometric titration. The results showed that the linearity test using calcium standard solution at a working range of 4-24 mg/100 mL had R2 of 0.9983, while the limit of detection and limit of quantification were 0.47 mg/100 mL and 1.57 mg/100 mL, respectively. The accuracy by spiking method at the spiking concentration of 60 mg/100 mL sample was 99.29%. The repeatability and intra-lab reproducibility showed acceptable precision with CV value of 0.98% and 2.59%, respectively. The results of ruggedness test showed that this method was rugged to the variation of sample volume and ethylenediaminetetraacetic acid (EDTA) concentration. This study proved that complexometric titration can be used to determine calcium content in fresh milk.

AbstractThe use of cassava as foodstuffs has been widely developed. Modifying it into a mocaf (modified cassava flour) is one of the cassava utilization. This research aimed to process cassavas into mocaf utilizing lactic acid bacteria and to obtain a better mocaf in terms of its physicochemical parameters. Bacteria used were L. plantarum, L. fermentum, and L. paracasei, which can ferment cassava to mocaf. The fermentation process was carried out by two fermentation duration of 48 hours and 72 hours, followed by draining and drying using the oven at 50 °C for 6 hours. This research analyzed mocaf's physicochemical properties such as water content, fat content, protein content, ash content, carbohydrate content, whiteness, and acidity. A Factorial Randomized Block Design with two replications was applied as the research design. If the test result showed that the tested sample has a significant difference at the level of significance of 0.05, it then subjects to the further Duncan test, using SPSS. The result showed that the use of L. paracasei produced best characteristics mocaf with a high protein content of 1.44%, an ash content of 0.31%, a white degree of 102.20, and a low degree of acid of 3.66.Keywords: cassava, fermentation duration, L.fermentum, L.paracasei, L.plantarum AbstrakPenggunaan ubi kayu sebagai bahan pangan telah banyak dikembangkan.

Titrasi kelatometri merupakan salah satu metode analisis kuantitatif yang dapat digunakan untuk menganalisa kadar kalsium. Sampai saat ini, belum ada data validasi analisis kadar kalsium secara titrasi kelatometri pada sampel minuman yogurt. Tujuan dari penelitian ini yaitu mengevaluasi metode penetapan kadar kalsium secara titrasi kelatometri pada sampel minuman yogurt. Hasil uji recovery menunjukkan bahwa metode titrasi kelatometri mempunyai nilai akurasi yang baik, yaitu 100,94% pada konsentrasi spiking larutan standar kalsium sebesar 60 mg/100 ml sampel minuman yogurt. Ripitabilitas dan intra-lab reprodusibilitas menunjukkan hasil yang dapat diterima dengan nilai relative standard deviation (RSD) berturut-turut sebesar 1,61% dan 1,74%. Hasil uji ketangguhan metode menunjukkan bahwa penggunaan sampel awal 5,0-10,0 ml menghasilkan kadar kalsium yang sama. Berdasarkan hasil ini, metode analisis kadar kalsium secara titrasi kelatometri dapat diaplikasikan pada sampel minuman yogurt.Chelatometric titration is one of the quantitative analysis methods that can be used to analyze calcium content.

Cookies are a type of pastry that is consumed by many people from all of aged. Cookies can be consumed as a practical and healthy alternative food. This research aims to formulate cookies combined from wheat flour and tempeh flour with addition of roselle. The use of tempeh flour in making cookies can increase protein levels because the protein content of tempeh flour is higher than in wheat flour. In addition, the important ingredients contained in the roselle petals are anthocyanin pigments that form flavonoids that act as antioxidants. The results of this study obtained 37.00% yield of tempeh flour and moisture content of 7.36%, ash content of 2.6%, protein content of 45.59%, fat content of 24.04 % and carbohydrate content of 0.134%. Roselle produced has yield of 80.5% and has a moisture content of 7.44 %, ash content of 6.28%, protein content of 6.29%, fat content of 1% and carbohydrate levels of 78.36%. Based on the result of hedonic test, formulas F1 was selected as the best formula. Products of tempeh flour cookies and roselle powder have a yield of 72 - 85.09%. The results of physicochemical analysis of F1 cookies obtained 2.40% ash content, 7.26% protein content, 29.62% fat content, 68.60% antioxidant activity EC50 µg/ml, 206.785

Melon is a type of fruit that has a high water content. High water content causes limited fruit storage, therefore it is necessary to preserve it to maintain the freshness of the melon. One method that can maintain the freshness of the fruit is edible coating. The purpose of this study was to determine the characteristics of organolepic melons given starch-based edible coatings from several types of tubers, namely cassava, canna, and lesser yam. This study used factorial Completely Randomized Design (CRD) with two factors. The first factor is the difference in CMC with a concentration of 1% and 1.5%. The second factor is the difference in glycerol with a concentration of 1% and 3%. The results of the study based on the ANOVA test showed that the type of starch treatment and the concentration between treatments did not have a significant effect on the texture, color, and aftertaste of the melon, but significantly affected the taste and aroma of the melon. So it can be concluded that from all edible coating formulations, panelists preferred the PS I formulation (cassava starch) with 1% CMC concentration and 1% glycerol.Keywords: cassava, canna, edible coating, lesser yam, melons
