Powder Addition

LATP-based composite electrolytes were prepared by sintering the mixtures of LATP precursor and La2O3 nano-powder. Powder X-ray diffraction and scanning electron microscopy suggest that La2O3 can react with LATP during sintering to form fine LaPO4 particles that are dispersed in the LATP matrix. The room temperature conductivity initially increases with La2O3 nano-powder addition showing the maximum of 0.69 mS∙cm−1 at 6 wt.%, above which, conductivity decreases with the introduction of La2O3. The activation energy of conductivity is not largely varied with the La2O3 content, suggesting that the conduction mechanism is essentially preserved despite LaPO4 dispersion. In comparison with the previously reported LATP-LLTO system, although some unidentified impurity slightly reduces the conductivity maximum, the fine dispersion of LaPO4 particles can be achieved in the LATP–La2O3 system.

Cookies merupakan salah satu makanan ringan yang disukai disemua kalangan umur. Umumnya cookies terbuat dari tepung terigu, memiliki kandungan karbohidrat dan lemak yang tinggi namun mengandung kadar serat yang rendah. Pada penelitian ini tepung umbi dahlia digunakan sebagai substitusi tepung terigu untuk pembuatan cookies kaya serat. Tujuan dari penelitian ini adalah untuk mengkaji penggunaan tepung umbi dahlia sebagai substitusi tepung terigu dan konsentrasi baking powder dalam formulasi pembuatan cookies. Rasio tepung umbi dahlia dan tepung terigu pada penelitian ini yaitu 15:85, 30:70, dan 45:55; dan konsentrasi baking powder yang digunakan yaitu 1–3% dari berat tepung. Metode Derringer’s Desirability Function digunakan untuk mendapatkan formula terbaik, dengan membandingkan kedekatan nilai karakteristik fisik cookies yang diberi perlakuan dengan karakteristik fisik cookies kontrol sebagai target. Hasil penelitian ini didapatkan formula terbaik untuk pembuatan cookies kaya serat adalah penggunaan rasio tepung umbi dahlia dan tepung terigu sebesar 30:70 dan penggunaan baking powder konsentrasi 3% dengan nilai total desirability (D) sebesar 0,87. Kesimpulan dari penelitian ini adalah cookies kaya serat berhasil dapat diproduksi dengan menggunakan tepung umbi dahlia dan jumlah penambahannya yang terbaik, dapat ditentukan.Effect of Substitution of Wheat Flour with Dahlia Tuber Flour and Concentration of Baking Powder on Physical Properties of Fiber Rich CookiesAbstractCookies are one of the snacks favored by wide range of consumers’s age. Usually, cookies made from wheat flour, which have high content of carbohydrate and fat but low content of fiber. In the present study, dahlia tuber flour was used to substitute wheat flour to produce fiber rich cookies. The effect of dahlia tuber flour was analyzed in the a varied baking powder addition. Dahlia tuber flour and wheat flour at ratio of 15:85, 30:70, and 45:55 (w/w); and baking powder concentration of 1–3% from total weight of the flour was usedas formula. Optimum formulation was obtained by Derringer’s Desirability Function, which compares the relation value of the physical properties of cookies made with dahlia tuber flour and control cookies which was made of wheat flour. The result showed that optimum formula to produce fiber rich cookies was obtained on the ratio of 30:70 and baking powder at concentration of 3%, with total desirability (D) value of 0.87. As conslusion, high fiber content cookies was succsessfully produced and the best dahlia tuber flour addition was determined optimally.

<p>The addition of garlic powder to gelatin from chicken claw waste was potentially developed as a natural preservative in food, especially for meat. Preparation of gelatin/garlic biocomposite was performed in three stages: synthesis of gelatin from chicken claw, garlic powder preparation as allicin source and preparation of biocomposite gelatin/garlic. The preparation of dry biocomposites was done by weighing the gelatin and garlic powder in weight ratio of 1 : 1 and 1 : 2 (w/w) in the total mass of 0.75 grams. For wet biocomposite preparation, the mixture of the powder was solved in 5 mL of lactic acid 2 %. Functional groups of gelatin, garlic and biocomposite were analyzed by <em>f</em><em>ourier transform infrared spectroscopy</em> (FTIR). The antibacterial activity of biocomposite against <em>Staphylococcus aureus</em> were tested using disc diffusion method. This test was performed on garlic powder, solvent and gelatin/garlic biocomposites powder in the ratio of 1 : 1 and 1 : 2 in 2 % lactic acid solvent. The biocomposite with a weight ratio of gelatin : garlic of  1 : 1 had the optimum diameter of inhibition zone. The effectiveness of biocomposite gelatin/garlic as natural preservative applied in meat was also physically studied by organoleptic analysis. Organoleptic analysis through the hedonic test was conducted on the parameters of color, smell, and texture of gelatin/garlic biocomposites-coated meat. The results showed that the addition of garlic can increase the effectiveness of gelatin as a natural preservative of meat for four days stored in closed packaging at room temperature.</p>

The purpose of this research is to determine the optimal dose of the addition of red spinach powder to artificial feed on the brightness of clown loach. This research was conducted at Aquaculture Laboratory Building 4 Faculty of Fisheries and Marine Sciences of Universitas Padjadjaran from April to May 2020. This research method is experimental with a Completely Randomized Design consisting of four treatments and three replications. The red spinach powder addition treatment used 0%, 2%, 4%, and 6% of the feed amount. The parameters observed are color value as primary data by using Toca Color Finder, while the growth, survival rate, and water quality as support data. Color assessment results were analyzed using the Kruskal-Wallis test, if there were significant differences, Z test would be performed. Growth data and survival rates were analyzed using Analysis of Variance (ANOVA). Because the F test results were not significantly different, the Duncan test was not carried out. The results showed that the addition of  6% red spinach powder is the best treatment with an increased color brightness value of 5,63.

This research was aimed to determine the quality properties, the microstructure of chicken sausage and Thiobarbituric acid (TBA) values with locally Indonesia red beetroot powder. The main ingredients of chicken sausage-making in this research were broiler chicken, filler, binder, beetroot powder, and spices. Red beetroot powder function as a filler was substituted tapioca starch in chicken sausage batter in three different levels. The combination of red beetroot powder with level 0, 1.0, 2.0 and 3.0% of total batter and shelf life at room temperature for 0, 1, 2 and 3 days. Each treatment consisted of five replications. The variables observed using quality properties (moisture, ash, fat, protein, crude fiber and calorie), microstructure and peroxide value of chicken sausage. The data of quality properties and peroxide value were analyzed by using one-way analysis (ANOVA) of Completely Randomized Design. The differences between means were analyzed by Duncan's New Multiple Ranges Test. The data of microstructure was analyzed by descriptive analyses. The moisture, protein, fat and ash contents for chicken sausages were significantly different (p<0.05). The chicken sausage with 2% substitution of beet powder produced chicken sausages with a high protein content of 14.77±0.02% while a low-fat content is 0.42±0.01%. Thiobarbituric acid (TBA) values of chicken sausages increased throughout the three days of room temperature storage (38°C). Chicken sausage formulated with red beetroot powder showed a significantly lower TBA value compared to the samples without red beetroot powder (p<0.05). In conclusion, a higher level of beetroot powder will improve the quality of chicken sausage and also the microstructure. The best level of beetroot powder addition was 2.0%. The addition of beetroot powder able to maintain fresh sausage conditions up to 2 days of storage at room temperature.
