Abstract

Dragon fruit skin has a very attractive red color that has the potential to produce anthocyanin pigments. Anthocyanin pigments are flavonoid compounds that are soluble in water and can be used as natural dyes in food and beverages. The purpose of this study was to see the effect of the number of multilevel extraction on the anthocyanin yield of dragon fruit peel extraction. 20 grams of dragon fruit peel powder with a mesh size of 20 was extracted in batches for 72 hours at room temperature using a mixture of distilled water and 10% citric acid (1:6) as a solvent. Variations in the number of stratified extractions were 1,2,3,4 and 5 times of extraction with the number of solvents respectively 500, 2 x 250 ml, 3 x 167 ml, 4 x 125 ml, and 5 x 100 ml. analysis of anthocyanin pigment levels using a spectrophotometer with a different pH method. The results obtained that the anthocyanin yield with samples 1 to 2 times of extraction increased by 6.35%, while the anthocyanin yield of samples 1 to 5 times of extraction increased by 35.65%. The highest yield of anthocyanin pigments was 4.1625 mg/20 grams in a multilevel extraction carried out for 5 times of extraction.

Abstract

Pineapple is a fruit that is commonly used by Indonesian people as a food ingredient. With the large production of pineapple, the amount of waste generated is also large, especially pineapple peel waste. The sugar content is quite high from the results of the study, it is known that the glucose content is 15.6% so that it can be utilized to produce bioethanol by further fermentation process by distillation. The purpose of this study was to determine the highest amount of ethanol in the variation of fermentation time and yeast weight. The process of making bioethanol in the early stages through the extraction process produces pineapple skin juice, then the fermentation stage at pH 4.5 using yeast and urea for optimal yeast growth and proliferation. To separate ethanol by the distillation process. In this study, variations in fermentation time were 2,4,6,8,10 and 12 days and yeast weight variations were 2,4,6,8, and 12 grams/200 mL. The results obtained for the optimal fermentation time produced the highest ethanol yield at 6 days of fermentation of 32.45% while the yeast used to produce the optimal ethanol yield was 4 grams and the ethanol yield was 30.78%.

Abstract

This research aims to study the production of essential oil from Piper Cubeba using the solvent-free microwave extraction (SFME) method. Before extraction, the raw materials are prepared in the form of grains and powders to vary the size of the raw materials. Time variation was carried out at microwave power 180 Watt Analyses were then performed on the resulting essential oil using both physical and chemical tests of density and solubility with 96% alcohol. Analyses of chemical compounds within the essential oil were then performed using the Gas Chromatograph Mass Spectrometry (GC-MS). It was found that the production of essential oil from Piper Cubeba using the SFME method was affected by microwave power, grain size, and treatment duration. Results from physical and chemical analyses revealed that the resulting cubeb oil has 0.86 g/mL density, which means that essential oil produced using the SFME method is lighter compared than those produced using MAHD methods. Results from GC-MS analyses showed eight components detected from the production of essential oil from Piper cubeba using the SFMEmethod; Copaene (39.28%), Cubebene (23.83%), Isoledene (11.66%), Naphthalene (6.65%), Phellandrene (5.81%), Asarone (5.71%), Cadidene (4.90%), and Caryophyllene (2.16%) which contents belong to the sesquiterpene group

Abstract

The Covid-19 virus in 2020 had a tremendous impact on almost all fields, one of which was in the field of education. Online learning is a solution for teaching and learning activities during the Covid-19 pandemic. This study aims to determine the effect of online learning on interest in learning in chemistry courses during the Covid-19 pandemic. Respondents taken were students of the Faculty of Industrial Technology, University of Nahdlatul Ulama Al Ghazali, Cilacap. The research design used linear regression analysis, with the data collection method in the form of a questionnaire. The results of the analysis for the normality test show a sig value of 0.200 more than 0.05 which means the data is normally distributed and the results of the linearity test show a sig value of 0.393 more than 0.05 which means that the correlation between online learning variables and interest in learning is linear. Based on the results of the linear regression test, the regression coefficient of 0.779 is positive, so it can be said that the direction of the influence of the variable x on y is positive. Based on the significance value: the table coefficients obtained a significance value of 0.001 <0.05, so it can be concluded that the online learning variable (x) has an effect on the learning interest variable (y). Based on the t-count value of 3.607> t-table 2.0484, it can be concluded that the online learning variable (x) affects the learning interest variable (y)

Abstract

Cooking oil is one of the primary commodities people need to process food. Repeated use of cooking oil at high-temperature heating produces foul smell that reduces the quality and nutritional value of fried food. Decomposition consists of    negative affects quality, but it also results in unfavorable flavor and reduced nutritional value of fried food. An alternative method to treat used cooking oil is adsorption with carbon made of coconut shells. This research aims to lower the levels of acid and peroxide numbers of used cooking oil by purifying it with activated carbon. The acid number determined using the acidimetric and alkalimetric titration method, while the peroxide number measured using the iodometric titration method. These two methods used to analyze samples of fresh cooking oil, used cooking oil, and used cooking oil treated with activated carbon. Results showed a decrease in acid number 34.1449% the second, 29.4103% the fourth use, and 37.5092% on the sixth use of cooking oil. Meanwhile, acidity reduced by 34.1508% the second use, 29.3883% the fourth use, and 37.5066% the sixth use of cooking oil. It found that peroxide number experienced a decrease in 81.2836% the second use, 85.3674% the fourth use, and 62.2462% the sixth use of purified cooking oil.

Abstract

The existence of water for the life of living things on this earth is very vital, humans in daily life need clean water for consumption, self-cleaning, farming, and other activities. Cilacap has many industries, where many industries bring waste to the waters. The method used for MAP (Magic Adsorbent Pipe) is by coagulating 50 g of rice husk and 50 g of coconut shell, then adding 100 g of coal fly ash, and then making pipe briquettes were made using the addition of aci flour adhesive. After that, the MAP pipes containing 3 kinds of adsorbents were tested for quality by color, pH, BOD, and COD tests. The air tends to be alkaline with a pH of 8 and becomes neutral with a pH of 7. Then the BOD also decreased from 7,442 mg/L to 6,363 mg/L and the amount of COD from 11,107 mg/L to 9,497 mg/L.

Abstract

Indonesia is a tropical area where various types of plants can thrive, one of the tropical trees, namely ketapang, is widely planted on the side of the road, in front of schools or in the yard of the house. The leaves of the ketapang tree have dense leaves every day, dry leaves can wither twice a year so that they become waste that is only thrown away or burned without being used properly. The content of ketapang leaves contains flavonoids, alkaloids and phenolics which contain antioxidants, anthocyanins and antibacterials. From this content, leaf extract of ketapang can be used as a natural dye in the manufacture of solid soap. The purpose of this research is how to extract ketapang leaves so that they have high economic value that can be used as natural dyes in the manufacture of solid soap. Ketapan leaf extract was tested for absorbance values using a uV-Vis spectrovoteer at a wavelength of 400 nm. Ketapang leaf extract with variations in mass of material, namely 20, 25, and 30 grams and extraction time of 24, 48 and 72 hours using ethanol as a solvent. The results obtained were the highest reduction in water content at a temperature of 800C, the highest absorbance yield was at a mass of 30 grams and an extraction time of 72 hours was 0.752 g/100 mL
