Abstract

Waste cooking oil (used cooking oil ) is oil derived from leftover cooking oil for frying food. Waste cooking oil is still considered as waste by some people and waste cooking oil that should not be suitable for consumption is sometimes still widely reused in food processing, this can endanger health and reduce the nutritional value of food. In order to be used and have economic value, it is overcome by synthesizing waste cooking oil into glycerol so it can be used as cosurfactant. Besides as cosurfactant, this waste cooking oil glycerol also can be used for various chemical industies, foods, cosmetics, and pharmaceuticals industries. For cosmetic preparation, it can make a nanocream preparation. The purpose of this research was to utilize waste cooking oil into a glycerol which is used as a cosurfactant, to characterize the synthesis results based on IR Spectroscopy data and to formulate it to nanocream preparation. The research was conducted in an experimentally by making glycerol from side product of waste cooking oil. Separating glycerol process conducted by transesterification reaction. Glycerol of waste cooking oil by product was characterized with IR Spectroscopy and evaluated include organoleptic, glycerol contents, density, viscosity, ash content, and moisture content. Formulation of nanocream preparation using 30% of Tween 80 as surfactant, glycerol by-product as cosurfactant 7,5% concentration, and 20% of VCO as oil phase. The nanocream preparation was measured for its particle size with the aim of being able to determine the particle size of the formula to form nanoparticle size. The results showed that glycerol of waste cooking oil by product shows the presence of OH, CH-aliphatic, C=O carbonyl and C-O. particle size of nanocream preparation obtained was 397,76 nm. Based on the result of this research, the conclusion is glycerol of waste cooking oil by-product can form nano size with presence of glycerol as cosurfactant. The particle size of the nanocream preparation obtained was still in the nanocream requirement range, namely 20-500 nm.

Abstract

Porang (Amorphallus muelleri Blume) is one type of tuber plant that has the potential to be developed in Indonesia. Porang plants have been reported to contain chemical compounds that have antioxidant activity. This research was conducted on the leaves of the porang plant with the aim of knowing the antioxidant activity, characterization, and phytochemical profile of the compounds contained therein. Compound identification and characterization were performed using standard methods, and antioxidant activity was determined using the DPPH (1,1- Diphenyl-2-picrylhydrazyl ) method. The results of the identification of chemical compounds showed that the ethanol extract of porang leaves contained chemical compounds of alkaloids, flavonoids, tannins, saponins, and steroids. The results of the examination of the simplicia characterization of porang leaves included the soluble ethanol content of 33.93%, the water soluble extract content of 17.3%, the ash content of 5.58%, the acid insoluble ash content of 0.235% and the water content of 8%. From the results of the simplicia characterization, it shows that the results meet the specified requirements. The results showed that the ethanol extract of porang leaves had antioxidant activity with an IC50 value of 93.04 µg/mL, which in this case is included in the category of strong antioxidant activity. Meanwhile, as a comparison, Vitamin C was used, which has an IC50 value of µg/mL, which is included in the category of very strong antioxidant activity.

Abstract

Shrimp in Indonesia are generally exported abroad after removing the head, tail, and skin. One alternative to the use of shrimp shell waste that has high economic value is processing shrimp shells into chitosan. The purpose of this study was to determine the shelf life of catfish using chitosan and to determine the optimal concentration of chitosan in catfish preservation. Chitosan applied to catfish showed that in the addition of a 0% chitosan solution, it had a shelf life of up to day 2 for 48 hours for a 0.5 solution; 1; 1.5 and 2% shelf life up to day 5 or for 120 hours. The most optimal concentration of chitosan for use in catfish is a 2% chitosan solution, and the total plate number (ALT) test meets the requirements of the SNI standard so that it can still be consumed.

Abstract

Coffee drinks are drinks that come from the processing and extraction of coffee beans. One of which is caffeine. Coffee contains approximately 24 of the most important substances. The purpose of this study was to determine the level of caffeine in coffee drinks from various types of packaging. The research stages include sample collection and preparation; identification of caffeine content; and examination of caffeine levels using UV spectrophotometry. The results showed that the three samples of coffee drinks sold at the minimarket in Jermal, Medan contained caffeine, and the levels of caffeine in coffee drinks were 26,352±0,292 mg/100mL (Sample A), 15,179±0,286 mg/100mL (Sample B), and 7,965±0,98 mg/100mL (Sample C). The caffeine content obtained meets the requirements of SNI, where the maximum amount of caffeine that can be consumed by the public in a day based on SNI is 50 mg–150 mg.

Abstract

Cancer is a disease characterized by uncontrolled cell division and the ability of these cells to invade other biological tissues, either by direct growth in adjacent tissues or by migration of cells to distant sites. The purpose of this study was to determine the class of secondary metabolites contained in the ethanol extract of cocoa leaves and their cytotoxicity by looking at the LC50 value using the Brine Shrimp Lethality Test (BSLT) method. This research includes phytochemical screening of ethanol extract and the BSLT method by looking at the number of deaths of Artemia salina leach larvae (LC50). The results of phytochemical screening tests showed that the cocoa leaves contained flavonoids, alkaloids, tannins, saponins, steroids, and glycosides. The cytotoxicity test with probit analysis showed an LC50 value of 269,15 µg/mL, so it was concluded that the ethanol extract of cocoa leaves was toxic and had potential as an anticancer.

Abstract

Shellfish is one of Indonesia's fishery commodities which is increasing every year, one of which is blood clams and feather shells, which are easily found in Southeast Asia and East Asia. Shellfish also have great potential so that it has an impact on the increasing waste that is allowed to accumulate without any handling of the pollution that exists in the environment and society. One alternative to the use of waste from feather shells to have a high use value is to isolate it into chitosan. The purpose of this study was to investigate the utilization of shellfish waste into chitosan and to determine the LC50 value of the chitosan produced. The analysis carried out was the toxicity test of chitosan from shellfish shell waste on Artemia salina Leach shrimp larvae using the Brine Shrimp Lethalitiy Test (BSLT) method with various concentrations of 100; 250; 500; 750; and 1000 µg/mL, and determining the value of LC50 by probit analysis. Based on the results of the toxicity test of chitosan from shellfish waste, the LC50 value was µg/mL. These results indicate that chitosan from shellfish waste has no toxic effect on Artemia salina Leach shrimp larvae.
