Abstract

The manufacture of air freshener gel using carrageenan and xanthan gum with patchouli oil as a fixative and coffee oil as a fragrance has been carried out, with carrageenan and xanthan gum content contained in a ratio of 30:70, 40:60, 50:50, 60:40 and 70:30as a gel base. With the addition of coffee oil which has a concentration variation of 1%, 2%, 3%, 4% and 5%. This study aims to determine the effect of variations in the composition of the mixture of carrageenan and xanthan gum on the characteristics of air freshener gel, patchouli oil as a fixative and coffee as a fragrance. From the best results, it was found that the best characteristics were found in G4 with ratio of carrageenan and xanthan gum 60:40. From the result of organoleptic test, it was found that the most preferred oil concentration was K3 with 5% coffee oil concentration. From the result of the liquid evaporation test at room temperature, the best result were N1 with 1% patchouli oil concentration, in the fan room the best results were N4 with 4% patchouli oil concentration and in the AC room the best results were N4 with 4% patchouli oil concentration. Meanwhile, the best fragrance resistance test results were found in N3 with a concertation of 3% patchouli oil

Abstract

The process of making pliek u is a traditional Acehnese food made from fermented coconut flesh. There are by-products, namely simplah oil and brok oil. Simplah oil is pliek u oil that is produced without going through the drying process in the sun. The purpose of this study was to remove the rancid odor of pliek u oil with the addition of cinnamon and citronella oil so as to reduce water content, free fatty acids and peroxide numbers. The stages of the research process include the mixing and soaking process. The process of mixing pliek u oil at a temperature of 90 C for 15 minutes by varying the concentration of cinnamon oil and citronella oil 5;0, 0;5, 5;2,5, 2,5;2,5, 5;5 and then it will be carried out immersion for 10, 20, 30, 40, 50 days. The results showed that the highest water content on the 50th day was 0.0733% and the lowest on the 10th day was 0.0033% while the best peroxide value was the ratio of 5:5 which tended to meet SNI but was not optimal. the best free fatty acids on day 30 and the optimum ratio in overcoming rancidity in pliek u oil was 4.67%. As for the organoleptic test (smell and color) the most preferred was on the 30th day with a ratio of 5;2.5

Abstract

Turmeric (Curcuma longa) is one of the most useful plants that can grow and develop throughout Indonesia. Turmeric is known to have high curcumin content so it has several pharmacological effects such as antioxidants. This study aims to produce a turmeric extract lotion preparation and to test the physical quality according to the Indonesian National Standard (SNI-16-4399- 1996). This research method is experimental which consists of making simplicia and extraction using maceration with 96% ethanol as solvent. The formulation used turmeric extract with a volume of 1 ml, 3 ml and 6 ml and the addition of carrageenan concentrations with a mass of 1gr, 1.5gr, 2gr, 2.5gr and 3gr. Evaluation of the physical quality characteristics of lotion preparations included organoleptic observation, homogeneity testing, absorbency test and pH test. The results showed that the three extract concentration formulas produced a homogeneous lotion, thick, smooth texture, odorless, light yellow, light orange and yellow. Hand and body lotion with the use of 3gr carrageenan added with 6 ml turmeric extract resulted in a homogeneous appearance; pH 7.0; viscosity 23600 cPs. The addition of turmeric extract produces hand and body lotion that meets the standards of SNI 4399-1996.

Abstract

Cellulose acetate can be made by utilizing raw materials that contain cellulose, one of which is waste paper. It has been reviewed that waste paper still contains high cellulose. The purpose of this study was to determine the effect of variations in temperature and reaction time on cellulose acetate products in the hydrolysis process. The method used in this research is cellulose activation, acetylation and hydrolysis with the steps taken include preparation of raw materials, delignification and purification of cellulose acetate. The synthesis of cellulose acetate was carried out by adding glacial acetic acid to the delignified paper, then adding acetic anhydride and sulfuric acid in the acetylation process to produce triacetate cellulose products, then the product was reacted with water to reduce the degree of substitution so that the resulting product was cellulose diacetate. The temperature variations used are 30, 40, 50 and 60 oC with time variations of 90, 120, 150, and 180 minutes. The product is then filtered and washed until neutral using distilled water. The resulting cellulose acetate was then analyzed for acetyl content, degree of substitution, and FTIR test. From the results of the research, the best acetyl levels and degrees of substitution were obtained at a temperature of 60 C and a time of 180 minutes, namely 39.46% and DS 2.42. The characteristics of cellulose acetate with FTIR of the functional group indicated the presence of cellulose acetate compounds with a sharp peak in the C = O ester group of the acetyl group with a wave number of 1622.13 cm-1 and the appearance of an O-H group from cellulose with a wave number of 3549 cm-1 and 3404. cm-1. Cellulose acetate produced from this research is a solid like white flour

Abstract

Fertilizer is one of the components needed by plants to get additional nutrients so that they can grow well and are not susceptible to disease. There are various types of plant fertilizers on the market and most of them are chemical fertilizers with inorganic synthetic content. The content is thought to be not good for health when applied to food plants in excess. Meanwhile, organic fertilizers are safer for humans because they consist of organic ingridients. Liquid organic fertilizer can be interpreted as a fertilizer that is formed naturally through a fermentation process that results in decay. In this study, the sample used was citronella waste as the main raw material obtained from the distillery. The fermentation method used is anaerobic. Based on the results of fermentetion carried out for 23 days, the pH of organic fertilizers was found to be in the range 4-5.39 where the range was still in accordance with the standard range of 4-8. The temperature is at room temperature with an averege of 30.8˚C. The levels of macronutrients produced have not yet reached the standard. Based on the results of the study, it can be concluded that the use of citronella waste alone cannot achieve the required levels of macro nutirents. Additional fermentation time as well as other components are suggested to get different results

Abstract

Packaging of food products using edible films plays an important role in protecting foodstuffs from microbial contamination and improving the quality of foodstuffs during storage. The addition of chitosan as an antibacterial with the aim of inhibiting pathogenic microbes that cause food contamination. This study aims to study the effect of increasing the volume of chitosan and glycerol on the characteristics of edible films. In this study, an edible film made from cassava starch-chitosan was made with various compositions of 5:5, 6:4, 7:3, 8:2 and 10:0 using the plasticizer glycerol 1; 1,2; 1.5; 1.7; and 2 ml. Furthermore, the characterization of the edible film was carried out including thickness test, water resistance test, ALT microbial test, FTIR test, and application to carrots to determine the shelf life. Edible film with a composition of 5:5 with a glycerol volume of 1 ml showed the best results, which had a thickness of 0.095 mm, water resistance 60.91%, and the number of colonies was 215 cfu/ml. In the application of edible film, carrots have a shelf life of 5 days, carrots coated with edible film still have good physique. Meanwhile, carrots that are not coated with edible film have fungal growth.
