This research wasaimed at figuring optimumpH and temperature of crude enzyme extract glukoamilase from isolate Gliocladium KEusing substrate of solid sago hampas. The research wasconducted by two phases, first wasfiguring optimumpH and second was optimum temperature. it wasbased on Complete Random Design. The data were statistically analyzed by using F test. If the result showedsignificance different,the analysis wascarried out by using Duncan’s New Multiple Range Test (DNMRT) with 5% tolerance. The result showedthat optimumpH ofcrude glukoamilaseextract from sago hampas was optimumpH of glukoamilasefrom Gliocladium KE using solid substrate of sago hampas waspH 6,0 with activity of enzyme 76,56 U/ml with final product of solube starch 0.09%, the level of reducing sugar 62,01%, and total sugar 78,43%. Optimum temperature was 60 ?C with enzyme activity 78,33 U/ml, final product of solube starch 0,13%, reducing sugar 63,04%, and total sugar 79,55%

Catechins are flavonoid molecules that act as antioxidants in the body. The degradation of palm oil with catechin treatment (400, 200, 100, 50, 0) was investigated in this work (ppm). The goal of this study was to see how efficient catechins are as antioxidants in cooking oil and what the optimal treatment would be for the amount of catechins added. Catechin concentration, antioxidant IC50, free fatty acid, peroxide value, water content, color, and fatty acid profile are all analyzed using GC-MS. Treatment E (400 ppm) was found to be the most effective, with free fatty acid values of 0.45 percent, peroxide value of 5 mek/g, moisture content of 0.89 percent, and color of 95.95 (L*16, 11, a* -1.51, b* 14.51). Catechins can retain three fatty acids in the oil, according to GC-MS analysis: hexadecanoic acid, 9-octadecanoic acid, and heptadecanoic acid.

Developing hard candy as a functional food with antioxidants and antibacterial properties derived from natural ingredients will do. By analyzing the formulation of innovations and analysis of the financial viability of hard candy products with the addition of gambir catechins, it is expected to provide information to stakeholders related to the development of hard candy innovation products with the addition of gambir catechins (Uncaria gambir Roxb.). The results of the analysis of organoleptic tests, obtaining formulas 17, 8, 18, 4, 7 hard candy had the rating respondents liked very much (4-5). Then conduct a quality test based on SNI hard candy 3547.1:2008 on products that have the criteria of organoleptic test results. Results from SNI hard candy test 3547.1:2008, the product met the standard requirements of SNI 3547.1:2008 products. When compared to hard candy products on the market with an average selling price of around Rp. 333.33, the hard candy products in this study can compete, especially strawberry variants. On a production scale of at least, 10 kg of hard candy HPP can compete with other products, where the hard candy in this study has a high added value antioxidant and has antibacterial properties useful for the health of consumers.

This study aimed to produce color indicator labels to determine changes in the physical and chemical quality of mangoes such as weight loss, total dissolved solids, vitamin C content during the ripening process at room temperature (±26oC), and determine the optimal storage time for viable mangoes. consumed. Measurements were made on Manalagi mango. The method used was a 2 factorial Completely Randomized Design (CRD), with variations of ammonium molybdate and chitosan. Each mango group was observed twice a day during storage at room temperature until the 10th day. The results showed that ammonium molybdate, potassium permanganate and chitosan could produce color indicator labels but did not change color during storage. The decrease in fruit quality during storage can be seen from the increasing weight loss percentage value, this is evidenced by the highest average SBK percentage value of S4 of 15.147% on the 10th day of storage. The increase in weight loss was caused by respiration and transpiration events in mangoes. The value of total dissolved solids increased until the peak of maturity occurred on the 4th day with the highest value of 11.50 oBrix and the lowest of 9.50 oBrix and then decreasing. The value of vitamin C levels increased until the 4th day of storage with the highest vitamin C content value of 34.32 mg/100g at P1 and the lowest being 24.64 mg/100g. It concluded that the optimal storage time for mangoes that are still fit for consumption is up to the 4th day of storage.

Characterization of Herbal Tea Bags Made from Starfruit Leaves (Averrhoa Bilimbi), Gotu Kola Leaves (Centella Asiatica) and Cinnamon Powder (Cinnamomun Burmanii) as Functional Drinks Fachrur Rozi; Diana Silvy; Daimon Syukri

This research aimed to study the characteristics of herbal tea bags from starfruit leaves, gotu kola leaves and cinnamon powder. This research used a completely randomized design with 5 treatments, namely differences in substitution of cinnamon powder 0%, 1%, 2%, 3% and 4% with 3 replications. The data obtained were analyzed statistically with ANOVA (Analysis of Variance) and if they were significantly different, then continued with the DNMRT (Duncan's News Multiple Range Test) test at a level of 5%. The results showed that the difference in the amount of cinnamon powder substitution had a significant effect on antioxidant activity, total water-soluble ingredients, total polyphenols, color, taste, and aroma. Differences in the concentration of cinnamon powder substitution did not significantly affect the water content and pH. The best treatment in this research was treatment E with substitution of cinnamon powder 4%. The results of organoleptic analysis were the average value of colour preference 3.95, taste 3.65, and aroma 4. The results of chemical analysis were pH 6.13 and antioxidant activity 36.93%.

One of the problems that often arise in the fisheries sector is to maintain quality. Chitosan as a natural preservative is an alternative because it is synthesized from shrimp shells and from invertebrate animal shells. Shrimp shell containing chemical compounds chitin and chitosan is a waste that is easily obtained and available in large quantities, which has not been utilized optimally, therefore it is necessary to utilize shrimp waste into chitosan as a preservation of freshness quality in tilapia. Realizing healthy food ingredients and types of preservation that are safe for the human body is the first step to improve a better quality of life. This study aims to determine the benefits of artificial chitosan as a preservative to improve the quality of freshness in tilapia (Oreochromis niloticus). The method in this research is an experimental method by preserving tilapia (Oreochromis niloticus) with different immersion times of artificial chitosan. The design carried out was a completely randomized non-factorial design. The observed parameters were the organoleptic test, the TVB test, and the test of the peroxide results from all tests showing that three hours of submersion was better than 1 and 2 hours of substation, all in relation to 7, 9 and 11 hours of observation. A seventh-hour observation is picking up no difference between 1, 2 and 3 hours of submersion.

Economic dispatch is often used in general to solve the problem of optimizing the fuel consumption of the electric power system, which focuses on developing optimization methods for a generation system. SCADA/PLC is used so that Economic Dispatch can run in real time on a system. In this research, an automation system will be designed that integrates Economic Dispatch into PLC in a generating system of 3 production boilers operating simultaneously (Cogent System) which aims to ensure that the Economic Dispatch system can run in real time. The simulation results show that the Economic Dispatch program on the PLC can run well. In the simulation of a steam load of 76 MT, the optimal value for boiler 1 is 45 MT and for boiler 3 it is 31 MT while in boiler 2 it is 0 MT, with the opportunity to save boiler fuel use by 16.8% and steam production cost can be reduced by 10% from its initial value.
