Ambar Hizmadin — 2024-02-29

This research was to determine the best CMC concentration treatment improve the stability of the emulsion and panelist acceptability milk of canarium nut. The study was based the RAL method with 5 treatments where A. 0% CMC, B. 0.4% CMC, C. 0.8% CMC, D. 1.2% CMC, and E. 1.6% CMC were then measured for emulsion stability, viscosity, total dissolved solids , pH measurement and panelist acceptability of canarium nut milk.

The results of measuring the stability of the emulsion A. 0,22%, B. 0,17%, C. 0,11%, D. 0,06% and E. 0,03%. The viscosity of A. 21,26 cP, B. 30,18 cP, C. 36,65 cP, D. yaitu 37,63 cP, dan E. 41,24 cP. Total dissolved solids A. 8.53 ˚Brix, B. 8.83 ˚Brix, C. 12.53 ˚Brix, D. 13.23 ˚Brix and E. 13.96 ˚Brix. The pH value of A. 6.60, B. 6.65, C. 6.72, D. 6.73 and E. 6.80. Milk of canarium nut with a concentration of 1,6% CMC resulted in the most stable emulsion level with a creaming index value of 0,03%. The addition CMC to milk of canarium nut did not improve the panelist acceptability because the highest average was in the treatment without the addition of CMC (0% CMC) with a value of 4,90 (much prefer).

The effect of Coconut Fruits as a Success Factor in Production of Virgin Coconut Oil by Oil-induced Fermentation

agustina sawo — 2024-02-24

The production of virgin coconut oil by the community is carried out using various techniques. One of them is fermenting using pure coconut oil as an inducement oil. However, production failures often occur. This study aims to examine the condition of coconut fruit as one of the success factors in production. There were 3 types of test samples, namely old coconuts (A), old coconuts containing kentos (B) and half-ripe coconuts (C). Production is carried out using the fermentation method and virgin coconut oil is used as the cooking oil. The three types of samples were treated the same, namely the volume of coconut milk, the volume of castor oil, the condition of room temperature and the length of time fermentation. The test was carried out 5 times for each sample. The success of the fermentation is indicated by the separation of the oil from the water and blondo. The results showed that of the 5 times of production, the highest production success occurred in sample A, which was 87%, while sample B was 40% and sample C was 20%. It was concluded that production using coconut milk from old coconuts (sample A), had a higher production success rate compared to coconut milk from B and samples C.

Dowens Melki Eldo Lepar — 2024-02-24

The aim of this study was to analyze the effect of citric acid concentration on the physicochemical properties of potato starch (Solanum tuberosum L.), especially the superjon variety. This study used a completely randomized design (CRD) method which consisted of 4 treatments and 3 repetitions. In treatment P0 (citric acid concentration 0% water 1000 ml). P1 (citric acid concentration 1% water 1000 ml). P2 (citric acid concentration 2% water 1000 ml) and P3 (citric acid concentration 3% water 1000 ml). The research results were processed using ANOVA, if there was a significant difference it would be followed by a 5% LSD test. The research results obtained were pH, 3.22-5.84, color, L* 69.53-75.76, a* -2.63-0.1, b* 13.03-19.63, levels water, 8.33-12.83%, ash content, 2.17-2.67%, gelatinization temperature 70.06-72.38°C, kamba density 0.81-0.85 gr/ml. The best physicochemical characteristics of potato starch were soaked in potato tubers in a 3% citric acid solution which had a characteristic L* value of 75.76, a* value of -2.63, b* value of 18.7, water content of 8.83%, degree acid (pH) 3.22, density 0.81 g/ml, gelatinization temperature 70.06°C, and ash content 2.17%. The use of citric acid in the processing of super jhon potato starch effectively inhibits the browning reaction. The characteristics of the flour produced have a significant effect, especially at higher levels of color brightness and low moisture content.

Jeanet Christina Rotulung — 2024-02-24

The aim of this study was to analyze the effect of moringa leaf extract on calcium content and evaluate the sensory properties of canarium milk. The research method used was a completely randomized design with five treatments: A (no moringa leaf extract), B (10% moringa leaf extract), C (10% moringa leaf extract), and D (30% moringa leaf extract), and E (addition of 40% moringa leaf extract), and each treatment was repeated three times. The results of the next study were analyzed using ANOVA, if it showed a real driver with a level of 5%, then the LSD test would be continued. The results showed that the calcium content of moringa canarium milk was 17.53 ppm – 535.12 ppm. Sensory properties using the liking level test, obtained the panelists' liking level for color ranging from 3.20 to 3.80 (neutral-like), aroma 2.94-3.64 (neutral-like), texture 3.16-3.68 (neutral-like), and taste 3.20-3.76 (neutral-like). The highest calcium levels were found in the treatment with the addition of 40% moringa leaf extract to canarium milk, and the sensory attributes of the color, aroma, texture, and taste of canarium milk after the addition of 40% moringa leaf extract were liked by the panelists.

Elstin Seilatuw — 2024-02-27

The purpose of this study was to analyze the swelling power, crude fiber content, and determine the best organoleptic characteristics of pancakes by mixing coconut dregs flour and wheat flour. The research method used was a completely randomized design (CRD) with 4 treatments with a ratio of coconut dregs flour and wheat flour, namely P1 (control), P2 (10%:90%), P3 (20%:80%), and P4 (30%:70%). Each treatment consisted of 3 repetitions. The research data were processed using ANOVA and continued with the LSD test at the 5% test level, if there was an effect between treatments. The results of the research on swelling power ranged from 35.42-44.2% with the highest swelling value obtained by pancakes with a mixture of 0% coconut dregs flour. Based on the organoleptic test, mixing 20% coconut dregs flour obtained the highest level of preference, with a rating of 4.48-5 (netral-rather like). Crude fiber content ranges from 2.06-3.81%. Pancakes mixed with 30% coconut flour had the highest crude fiber content.
