DAN GLISEROL DARI MINYAK JELANTAH DENGAN PENAMBAHAN TiO2The manufacture of bioplastics from potato starch (Solanum tuberosum L.) and glycerol from leech oil with the addition of TiO2 has been done by varying the concentration of TiO2. This study aims to study the effect of the addition of TiO2 on the physical, mechanical properties and bioplastic biodegradation rate of cassava starch and glycerol from leech oil. The research was conducted by making glycerol from used cooking oil, making bioplastic films with various concentrations of TiO2 0; 1; 2; 3 and 4%, characterization of bioplastics which includes physical, mechanical and chemical properties as well as biodegradation tests using the soil burial test method. The addition of TiO2 as a bioplastic filler can affect the physical, mechanical properties and the rate of biodegradation in the soil. The results showed that each addition of 1% TiO2 increased the thickness by 22,966 microns, increased the tensile strength value of 0.0853 N/mm2, decreased elongation by 5.0987%, and increases the average Young's modulus by 0.0599 MPa. The best bioplastic mechanical test results were produced at a starch composition of 2.5 grams and 2% (w/v) of TiO2 particles. The addition of TiO2 did not have a significant noticeable difference to the rate of biodegradation. However, it has a close correlation between the loss of bioplastic mass and the length of burial.NIM.: 18106030021 Siwi Qoirinisa2023-02-16T00:45:20Z2023-02-16T00:45:20Zhttp://digilib.uin-suka.ac.id/id/eprint/56285This item is in the repository with the URL: http://digilib.uin-suka.ac.id/id/eprint/562852023-02-16T00:45:20ZPENGARUH PENAMBAHAN GLISEROL DARI MINYAK JELANTAH PADA EDIBLE FILM DARI PATI KENTANG TERHADAP MASA SIMPAN BUAH TOMATThe fabrication of edible films from potato starch with the addition of glycerol from used cooking oil as a plasticizer and its application to tomatoes for a shelf life of 4, 8 and 12 days. This study aims to determine the effect of adding glycerol from used cooking oil to the physical properties of edible films and to the shelf life of tomatoes coated with edible films. Edible film was made by adding 0, 10, 20 and 30% glycerol from used cooking oil (v/w starch). The glycerol functional group test of used cooking oil was carried out using Fourier Transform Infrared (FTIR). Physical characteristics test of edible film includes thickness, tensile strength, elongation and water vapor transmission rate tests. Meanwhile, the shelf life test of tomatoes coated with edible film included weight loss and sugar content tests of tomatoes. The results of the fabrication of glycerol from used cooking oil in this study were having a hydroxyl group (O-H), a methylene group (-CH2-) and a -C-H group with a pH of 6.66 and dark brown in color. The addition of variations of glycerol from used cooking oil to the physical properties of edible films does not significantly affect the addition of the thickness of the edible film, but it greatly affects the decrease in tensile strength, increase in elongation and increase in the rate of water vapor transmission as well as optimum addition of 10% glycerol. The addition of glycerol from used cooking oil was very influential on the 4th day of storage in reducing the percent weight loss of tomatoes and the 12th day of storage in increasing the percent weight loss of tomatoes. Meanwhile, on the 8th day of storage, it did not have much effect on reducing the percentage of weight loss of tomatoes. For the sucrose content of tomatoes, the 4th day of storage did not significantly affect the decrease in the sucrose content of tomatoes, while the 8th and 12th days of storage had an effect on the reduction of the sucrose content of tomatoes and the optimum was at the addition of 10% glycerol.NIM.: 18106030023 Mutiara Eka Permata2023-02-16T00:45:15Z2023-02-16T00:45:15Zhttp://digilib.uin-suka.ac.id/id/eprint/56286This item is in the repository with the URL: http://digilib.uin-suka.ac.id/id/eprint/562862023-02-16T00:45:15ZISOLASI DAN KARAKTERISASI GELATIN HALAL DARI KULIT IKAN TAWES (Barbonymus gonionotus)The extensive use of gelatin products in various industries has led to an increase in the number of gelatin imports every year until now. The increase in the number of requests for halal gelatin in Indonesia is not matched by the quantity of halal gelatin production. One of the animals that can be used as a source of halal, economical, and easily available gelatin is fish. This study aims to isolate gelatin from tawes (Barbonymus gonionotus) skin and determine its chemical (ash content and pH) and physical (moisture content and viscosity) characteristics. Gelatin was isolated by acid hydrolysis method using 0.05M acetic acid (CH3COOH) solution. In this study, various pretreatment treatments were carried out using 0.05 M, 0.075 M and 0.1 M NaOH solutions. Extraction was carried out using distilled water as a solvent heated at 45˚C for 16-18 hours. The results of characterization using the FTIR spectroscopy method showed that the isolated product showed absorption groups typical of gelatin amide A at wave numbers 3600 – 2300 cm-1, amide I at 1661 – 1636 cm-1, amide II at intervals 1560 – 1335 cm-1, and amide III at intervals of 1300 – 1200 cm-1. Gelatin products from tawes skin have a pH in the range of 3.6-6.5, water content <16%, ash content <3.25%, and viscosity in the range of 2.5-5.5 cP which meet the requirements for gelatin quality based on SNI 06-3735-1995. The results of this study are expected to support diversification of halal gelatin sources to meet industrial needs in Indonesia.NIM.: 18106030045 Annisya Sayyida Hafshah2022-10-21T07:13:50Z2022-10-21T07:13:50Zhttp://digilib.uin-suka.ac.id/id/eprint/54397This item is in the repository with the URL: http://digilib.uin-suka.ac.id/id/eprint/543972022-10-21T07:13:50ZPEMANFAATAN SERBUK NANAS (Ananas comosus) SEBAGAI SUMBER ASAM ORGANIK TERHADAP ADSORPSI ZAT WARNA REMAZOL REDAdsorption research had been carried out using organic acids from pineapple (Ananas comosus) to reduce remazol red dye.
