Abstract

The silk worm is feed for fish seeding. The silk worm supplying for that necessity majority still got from river and ground drain. But the river and drain flow that polluted obstruct the silk worm population, growth, and development in wild nature. Another that every rainy season the river and drain flow being swift until washed away the majority silk worm until decrease the silk worm for that necessity. Caused by it necessary conducted the silk worm breeding, in this moment use oyster mushroom media waste and organic vegetable as breeding media, with fermented use EM4 for increase the silk worm biomass. This research uses Complete Random Design with 2 factor (oyster mushroom media waste and organic vegetable) and 3 treatments (0%, 25%, 50% EM4 gift). Then the research data result is analyzed use 1 way Anova test P<5%. If analysis result is show effect, then data analysis continued to 5% LSD test to know that resulted effect is significant or no. This research result is show that cultivation media type with EM4 gift that result the highest silk worm biomass is organic vegetable media with 25% EM4 gift result 11,76 gram the silk worm wet mass with 0,196 gram/day daily growth average speed, and 6,82 gram the silk worm dry mass with 0,11 gram/day daily growth average speed.

Abstract

Microalgae have good potential in the food sector. Microalgae cultivation was carried out to obtain as much biomass as possible. Microalgae biomass contains carbohydrates, proteins, and lipids. This study aims to determine the effect of providing a carbon source in the form of waste sugar (molasses) on the carbohydrate, protein and lipid content of Galdieria sp. microalgae. The cultivation method used is the batch culture method, namely cultivation without continuous addition of media. Cultivation used 5 treatments with 3 replications. The results obtained from this study were that the concentration of 5% molasses waste had a significant effect on the content of carbohydrates, proteins and lipids

Abstract

Robusta coffee (Coffea canefora) is a type of coffee that is widely cultivated in Indonesia. Fermentation affects the taste of the coffee that is formed, if it takes too long it will cause a distorted taste because it is over fermented, whereas if it is too fast it will cause a less formed taste. This study aims to determine the levels of caffeine, ethanol and pH of Robusta coffee (Coffea canephora) powder. This research method used a one-factor Completely Randomized Design (CRD) with a long fermentation time with 3 repetitions. This research was conducted at the Jember State Polytechnic Food Analysis Laboratory. The time used in the fermentation process is 7 different times, namely 0, 6, 12, 24, 36, 48, 54 hours with a temperature of 32-35°C. The data obtained will be analyzed descriptively, if there is an influence on the treatment then the Duncan test will be continued. The results of this study showed that the caffeine content produced a very significant difference in the length of time of fermentation with a value range of 1.98% - 3.47%. This shows that the higher the fermentation time, the lower the value of caffeine content. The ethanol content was significantly different in the length of time of fermentation with a value range of 0.2 -0.8 with a level of P<0.01. The results of the tests that have been carried out are classified as unfit for consumption at a fermentation time of 6 hours to 54 hours, it is necessary to carry out a further process to remove the ethanol content in coffee beans. pH test with significantly different results on the length of time of fermentation with a value range of 5.17-5.28. Based on the test results that have been carried out, Argopuro robusta coffee is classified as fit for consumption. Fermentation time affects the levels of caffeine, ethanol and pH in Argopuro Robusta coffee powder.

Abstract

This study aims to determine the physical quality characteristics and the effect of adding pineapple concentration on the hedonic test of the Robusta Argopuro coffee method honey process. The research method used a completely randomized design with a single factor in 3 treatments using pineapple pulp concentrations (30%, 50%, and 80%) with 3 replications. The results of the study did not find live insects and the appearance of a moldy or rotting odor in the coffee greenbean with a defect value of 9.5 is included in the quality category 1. The seed size test results in a large seed size classification. The water content test produced the highest value of 9.97 at 80% concentration and the lowest 9.33 at 0% concentration and the hedonic test of aroma, color, sweetness, acidity, fruity, bitter, body, aftertaste, balance, and, overall produced the highest values in a row, namely 3.46 at a concentration of 0%; 3.56 at 50% concentration; 3.09 at 80% concentration; 3.22 at 80% concentration. 3.06 at 80% concentration; 3.24 at 50% concentration; 3.20 at 80% concentration; 3.38 at 30% concentration, 3.34 at 80% concentration; and 3.47 at 80% concentration. On the results of the physical quality test of coffee greenbean complies with SNI 01-2907-2008 standard. %. Argopuro robusta coffee brew honey process with the addition of pineapple pulp at a concentration of 80% produced the highest hedonic value.
