Abstract

Red dragon fruit contains anthocyanins which act as natural dyes with a purplish red color. The purpose of this study was to determine the characteristics of red dragon fruit as a raw material for natural coloring pigments and to determine the effect of blanching on the characteristics of the red dragon fruit pigment ethanol extract. The study was conducted using a laboratory experimental method using a completely randomized design (RAL) with a single factor, namely blanching time. The blanching time is denoted by 1 (0 minutes), 2 (3 minutes), 3 (5 minutes) and 4 (7 minutes). Data from research results related to red dragon fruit are presented in tables and analyzed descriptively, while data from ethanol extract of red dragon fruit pigments were analyzed by linear regression analysis. The results showed that the pH of the raw material characteristics was highest in the fresh treatment and the lowest in the blanching treatment. The results of the highest lightness, redness and yellowness were obtained in the blanching, blanching and fresh treatments, respectively. While the lowest values ​​were in the fresh, fresh and blanching treatments. The highest total dissolved solids yield was in the fresh treatment and the lowest was in the blanching treatment. Blanching treatment has an effect on yield, reddish color, total dissolved solids and has no effect on pH, color intensity and color lightness.

Abstract

Fermentation is one of the processes in tobacco processing which will be used as raw material for cigars. One of the main aspects that must be considered to achieve successful fermentation is the temperature and humidity of the fermentation room, namely 60-80% RH and 27-32 °C. KOPA Tarutama Nusantara (TTN) Jember is a Under Shade Tobacco processing unit with manual monitoring of temperature and humidity using a hygrometer which causes workers to experience fatigue and delays in taking action if the temperature and humidity are not up to standard. Based on these problems, an IoT (Internet of Things)-based temperature and humidity monitoring tool is needed. The research was carried out by assembling tools using Arduino Ide, DHT 11 Sensor, 2 Channel Relay, LM2596 and programmed with Arduino Ide software. Based on the functionality validation test, this tool can be said to function properly because the X value is 1. The efficiency value is declared very efficient with a value 6.9% and the effectiveness value is declared very effective because the effectiveness value increases from 17 to 22. The implementation of this tools in the fermentation room also increases the effectiveness of tobacco quality with a value of 112.9%.

Abstract

Determination of the number of workers is one step to increase efficiency and productivity. Packaging has an important role to increase productivity. The purpose of the work measurement is to determine the standard time with the work sampling method so that it can be seen the number of workers needed. Observation of 2 trained workers for 10 days with 30 observations per day. The results showed that the average productive percentage in shift 1 of labor 1 was 96% and labor 2 was 93%. While in the second shift 2 workers have a productive percentage of 92%. The standard time in shift 1 is 1,2946 minutes/unit with a load of 233.28% and 1,3009 minutes/unit for a workforce with a load of 263.55%, while in shift 2, the workforce 1 is 1.3038. minutes/unit with a load of 320.16% and a workforce of 1.3401 minutes/unit with a load of 346.84%. Based on the calculation of the efficiency of shift 1 workers with efficient achievements of 95.00% and 86.67%. Likewise, with the efficiency of shift 2 workers with efficient achievements of 88.33% and 86.00%. So the number of workers needed is 5 people/machine.

Abstract

Biodegradable foam is a type of environmentally friendly packaging made from biopolymers in the form of starch that can be degraded naturally. This study aims to determine the characteristics of biodegradable foam and its prototype made from cassava starch as a biopolymer substitute for synthetic polymers by adding variations of bagasse flour to compact the structure and polyvinyl alcohol (PVA) which functions to reduce water absorption. The stages of making biodegradable foam are started by making bagasse flour, making biodegradable foam sheets using the baking process, and making a prototype bowl of biodegradable foam. The making of this biodegradable foam consists of 6 formulas by adding variations of bagasse flour (5%, 10%, 15%) and PVA (20%, 40%) from 36 grams of starch mass. The tests carried out were in the form of water absorption, biodegradation, thickness, tensile strength, and density tests. The best treatment was found in the A3B1 formula which was used as the basis for making a prototype bowl of biodegradable foam. The addition of variations of bagasse flour and PVA had a significant effect on the characteristics of water absorption and biodegradation, while the other characteristics were only PVA which had a significant effect. The results of the best treatment as the basis for making a prototype bowl of biodegradable foam with water absorption characteristics of 25.93% and biodegradation of 45.95%.

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

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.
