Abstract

In this study, squeezed orange peel was distilled by water vapor distillation method to extract its essential oil, which can be used as an antioxidant. The fixed variable is the weight of 3 kg of squeezed orange peel with a size of ±1 cm-2 cm and a temperature of 125 ℃ and a pressure of 1.2 bar. Independent variables are the ratio of squeezed orange peel:water 1:2, 1:3, 1:4, 1:5, sampling time, 3 hours 4 hours 5 hours and 6 hours. The dependent variables are essential oil yield analysis, essential oil density analysis, essential oil refractive index analysis, essential oil component analysis by GC-MS and essential oil antioxidant analysis by DPPH method. The most yield and volume of squeezed orange peel oil was obtained at a ratio of 1: 2 with a sampling time of 6 hours, namely as much as 1.2289% and 43 mL. From the density obtained, all samples of squeezed orange peel essential oil meet SNI 06-0009-1987 while the closest to ISO 3140, 2019 is the 1:2 ratio of squeezed orange peel essential oil. From the refractive index obtained, the closest to SNI 06-0009-1987 and ISO 3140, 2019 is the 1:2 ratio of squeezed orange peel essential oil. From the component test and antioxidant test, the highest dl-Limonene composition was obtained at a ratio of 1:5 with a sampling time of 6 hours, namely 54.94% and very strong antioxidant strength of 49.07 µg/mL.

Abstract

Utilization of aluminum metal powder waste left over from the plate rack which is wasted can apparently provide economic value as raw material for making coagulants. Aluminum powder waste contains 88.74% aluminum. The high aluminum content makes plate rack waste potentially as raw material for the manufacture of polyaluminium chloride (PAC). This study begins with the manufacture of AlCl3 monomers on 4 grams of aluminum metal weight, by varying NaOH concentrations (44, 45, 46, 47 and 48%) and variations in HCl concentrations (31, 32 and 33%). Next the AlCl3 monomer is converted to PAC polymer. The results on variation of 48% NaOH and 32% HCl with pH 3.6 and specific gravity 1.23 g / ml. This result is in accordance with SNI 06-3822-1995 quality standards. This study also tested the ability of PAC to reduce turbidity in well water, with a pH of 4.30 and a decrease in turbidity of 94.94%. Can produce PAC that is more economical and has met the standard qualityof conventional SNI PAC.

Abstract

Emulsifiers or emulsifying agents are one of the oleochemical products that have high economic value. One of the alternative ingredients that can be used as emulsifiers is Aceh palm oil (pliek u oil). In this study n-Butanol solvent is used which can increase the solubility of oil in glycerol so that the glycerolysis reaction can be carried out at low temperatures. This study aims to determine the effect of temperature and solvent ratio on the emulsifier produced. The catalyst used in the reaction is MgO (4% of oil weight), where the test variables used are reaction temperature (70, 80, 90, and 100◦C), 2 hours contact time, and the ratio of n-butanol to oil ( 1: 1, 1: 2, 1: 3 and 1: 4 v / v). The analysis was carried out in the form of an analysis of decreased levels of free fatty acids (ALB) by acid-base titration and Hydrophilic Lipophilic Balance (HLB) analysis to determine the type of emulsifier produced. The results showed that the greatest decrease in free fatty acid levels was found in the solvent to oil ratio of 1: 4 (v / v), and the temperature of 100◦C was 91.26%. The resulting HLB value of 19.68 is categorized into oil in water (o / w). The results obtained from this study indicate that pliek oil can be used as raw material for making emulsifiers using n-Butanol solvent and MgO catalyst.

Abstract

Turmeric contains chemicals that are benefical for the health of the body and can be used for making cosmetics. This study aims to make blush on cosmetics from natural ingredients with some benefits that not only increase external beauty but also nourish the skin from within by utilizing the natural color of the turmeric plant. Turmeric extraction was carried out using ethanol as a solvent using the maceration method. Maseration is done for 3x24 hours. This study used variations in the concentration of turmeric extract as mush as 4ml, 6ml, 8ml and 10ml with variations in the concentration of talcum as much as 0gr, 0.5gr, 1gr, 1.5gr and 2gr. The testing that has done includes flavonoid test, pH values, irritation test and organoleptic test. The results of this study showed us that the best blush on with a composition of 8ml turmeric extract with 0.5gr talc has a positive flavonoid value, a pH value is 4.9 compatiable according to the pH of face skin, which 4.6-7, an irritation test value of 0 indicates that the blush on does not irritate the skin and the organoleptic test results have an average color value of 4.2, and average aroma of 4.3 and an average texture of 4.0.

Abstract

Oil palm (elaies) is a tropical plant that is widely found in Indonesia. The increasing production of this plant has an impact on the increasing amount of oil palm frond waste every year. During this time, the community only utilizes the fruit for the manufacture of CPO while the fronds are discarded and become waste. Palm frond waste contains constituent components in the form of cellulose and lignin so that it has the potential to be utilized as an adsorbent. The manufacture of activated carbon is carried out with the stages of carbonization and activation using H3PO4. The finished activated carbon was then tested for moisture content, ash content, and iodine absorption according to SNI 06-3730-1995, functional group analysis testing with Fourier Transform Infra Red FTIR and Fe metal ion absorption test in well water using an AAS spectrophotometer. From these tests, 7% moisture content, 4% ash content and 909.45 mg/gr iodine absorption were obtained. FT-IR testing obtained 11 fungal groups and Fe metal absorption using an AAS spectrophotometer obtained 77%, so it can be concluded that the activated carbon made is in accordance with SNI 06-3730-1995 specifications
