Acid gelugur fruit (Garcinia atroviridis) is one of the Garcinia families that has long been used as traditional medicine. Gelugur acid has been widely used as a cooking spice by Malay people, but it also has the ability to reduce cholesterol. Besides that, it has antioxidant properties and can reduce body weight and cholesterol. The purpose of this study was to establish specific parameter standards and non-specific parameters from the ethanol extract of acid gelugur fruit. The extract was obtained by maceration method using 70% ethanol with a rendament of 37.15%. Specific parameters include observations of organoleptic extracts of tamarind fruit showed, dark brown, distinctive smelling, and sour. Contains several sekendur metabolites such as flavonoids and saponins. The level of the compound that is soluble in water is 3.6%, while the content of the compound dissolved in ethanol is 3.9%. Total ash content of 2.99%. Non-specific parameters include acid insoluble ash content of 1.03%. The drying rate of geluguric acid simplicia was 7.20%. Water content of sour fruit gelugur extract was 13%.

Pedada fruit (Sonneratia caseolaris) is one of the mangrove varieties that has a high nutritional content and has the potential as an antioxidant. In general, pedada is still underutilized by the community because it tastes sour and feels tight when consumed directly. One of the efforts in utilizing the pedada fruit is processing it into jelly candy. The purpose of this study was to determine the chemical characteristics of pedada jelly candy with the addition of carrageenan. This research is an experimental design using a quantitative descriptive approach with P2K2(100 ml  of pedada fruit juice and 20 gr carrageenan) and P0K2 contol samples (without pedada fruit juice and 20 gr of carrageenan). To find out the chemical characteristics were tested Carbohydrate, protein, fat, fiber, water content, ash content, vitamin C and Antioxidant activity. This research was conducted in May-August 2018. Jelly candy making was carried out at the STIKes Baiturrahim Jambi Nutrition and Food Laboratory, Chemical characteristics were tested by proximate analysis (Carbohydrate, protein, fat, fiber, water content, ash content), iodimetry (vitamin c) method and DPPH (Antioxidant activity) method. The best treatment in making Pedada jelly candy which is very preferred, namely P2K2 (100 ml pedada fruit juice and 20 gr carrageenan) with a carbohydrates (69.83%), protein (5.66%), fat (9.89%), water content (39.26%), ash content (9.67%), fiber (0.67%), vitamin C (14.08%) and antioxidant activity (67.34%).

Sofo-sofo leaves are traditional medicinal plants that have been known by the Nias people to cure fever, coughs, diarrhea and antimicrobial infections on the skin surface. The  purpose  of  this  study  was  to determine the antibacterial activity of ethanol extract, n-hexane fraction and ethylacetate fraction Sofo-sofo leaf (Acmella cf) against Propionibacterium acnes and Staphylococcus epidermidis. Simplicia powder was characterized and phytochemical screening was performed. Furthermore, it was isolated using 96% ethanol solvent and fractionated with  n-hexane and ethylacetate to obtain extracts. Then test the antibacterial activity of each extract against Propionibacterium acne and Staphylococcus epidermidis by using a diffusion method disc paper. The research results obtained water content 5.66%, water soluble extract content 27.33%, ethanol soluble extract content 13.61%, total ash  content 14.39%, and  acid insoluble ash content 6.25%. The highest antibacterial activity was given by ethylacetate extract at a concentration of 2% (23.4 ± 0.2) compared to ethanol extract with a concentration of 2% (21.06 ± 0.85) and 2% concentrated n-hexane extract (19.36 ± 0.16) against the Propionibacterium acne bacteria. The highest antibacterial activity was ethyl acetate extract at a concentration of 2% (23.24 ± 0.23), ethanol extract with a concentration of 2% (16.36 ± 1.76) and n-hexane extract at a concentration of 2% (15.36 ± 0 , 11) against Staphylococcus epidermidis bacteria. The  antibacterial activity results were analyzed by the one way ANOVA test method.

The olive oil industry represents an important productive sector in the Mediterranean basin countries. Olive stone is an essential by-product generated in the olive oil extraction industries and it represents roughly 10% by weight of the olive fruit. The seeds of pickled olives are also a significant waste product. In the present study, we have investigated the possibility of the use of differential scanning calorimetry for the thermal characterization of seeds from green and black pickled olives from Croatia. The differential scanning calorimeter (DSC) with a normal pressure cell equipped with a cooling system was used to determine the thermal properties of seeds from olives. The following analyses were also performed: the determination of calorific values in a pressure bomb calorimeter, the determination of initial water content, the determination of changes of water content during drying at the temperatures of 30 °C, 50 °C and 80 °C, the determination of a percentage content of seeds mass to the mass of the whole olives, and the determination of ash content. Seeds from olives are characterized by very good parameters as a biomass. The analyzed olive seeds were characterized by low water content, low ash content, and a relatively high caloric value.
