Abstract

Red cabbage is a plant that is rich in antioxidant, one of its secondary metabolites, antosianin that gave the purple color on red cabbage has multiple health effects for human such as preventing cancer, tumor, and many more. The use of this secondary metabolites in plants nowadays is very popular, not only for its pharmacological effects, but also as an antibacterial, coloring agent, flavoring agent, natural pesticide, etc. Therefore, this study is needed to look for another potentially benefical compound in the plant, such as red cabbage, a plant that is more than just a salad. The aim of this study was to determine the effect of the types of extraction solvents on phytochemical compound of red cabbage plant leaves. The dried off plant macerated with two kinds of solvents, aquades, and ethanol. After about +3 days, both of the extract got evaporated with rotary evaporator. The yields of evaporating will be tested with GCMS analysis. The result showed that kind of extraction solvents do affect the yield from evaporating, and GC-MS analysis. Aquades showed to have a better capability in both of extraction, or on the analysis with GC-MS.

Abstract

Kelor (Moringa oleifera) is a plant that grows in tropical climates including Indonesia. All parts of this plant can be used as medicine and other natural products. The purpose of this study was to determine the bioactive compounds contained in moringa stem bark and the level of toxicity expressed by an LC50 value of less than 1.000 ppm so that it can be used as traditional medicine and other natural products. Identification of bioactive compounds in moringa stem bark using the GC-MS analysis method and toxicity test on Artemia salina Leach shrimp larvae using the Brine Shrimp Lethality Test (BSLT) method. Based on the results of the analysis using GC-MS showed that moringa bark extract contains 14 bioactive compounds. The highest bioactive compounds in the 3 peaks were secondary metabolites in the form of phenols and monoterpenoids. The toxicity test of moringa bark extract against Artemia salina Leach larvae showed that the higher the concentration, the higher the percentage of mortality of Artemia salina Leach, so that the calculated LC50 value of moringa bark extract was toxic, which was 149,689 ppm.

Abstract

Coffee fruit contains high cellulose and lignin. Cellulose is the most abundant polysaccharide found in plants, cellulose in nature forms crystals so that cellulose is difficult to degrade. Cellulose can be broken down using cellulase enzymes produced by microorganisms. One of the microorganisms capable of producing cellulase enzymes which are used to hydrolyze cellulose into simpler products, namely glucose, is cellulolytic bacteria. The purpose of this study was to identify bacterial isolates that ferment in coffee cherries. The isolation results obtained 97 bacterial colonies that grew, based on observations of color, shape, edges, and surface, they could be grouped into four groups of bacterial isolates named M1, M2, M3, and M4 bacterial isolates, with each cellulolytic index (IS) of 3,00; 0,75; 2,00 and 3,00. The results of the gram stain test obtained one gram-negative bacterial isolate (M2 rod-shaped) and three gram-positive bacterial isolates (M1 in the form of a focus, M3 and M4 in the form of a rod). Bacterial isolates M1 and M3 degraded the earliest coffee cherries with an average of 2.66 days after inoculation and no later than 6 day after inoculation in M2M4 and M3M4 bacterial isolates. The ability to degrade bacterial isolates in coffee cherries was obtained 2 - 5.34 days faster than the control.
