Abstract

Community Service in the Village Lembu, District of Bancak on 2015/2016 focused on training the manufacture of cosmetic products. The most mothers Household of PKK’s member supplied and trained in one skill, namely the training of cosmetic products, such as soaps, lotions and others. Service activities packaged in the form of community empowerment by methods PRA (Participatory Rural Appraisal) to form the basis of a briefing about the character cosmetic products and training products manufacture. The implementation steps include the stage of awareness of materials, devices used when creating products and maturation/curing of the product before use. The practice of making cosmetic conducted in groups and each group of at least 5 people. Completeness is the continuity of the motivation for the manufacture of cosmetic products which are prepared to serve the needs of the market. From the results of development activities can be concluded that the public powerful of time management and become skilled productive use of household appliances for the production of cosmetics, and does not stutter anymore to make cosmetics with the appropriate technology. Marketing begins with consumers who come from the rural communities Lembu, then slightly extends in the District Bancak. Two excellent products that can meet the needs of the community are soaps and lotions with a sale value of Rp. 10.000/100 ml. Monitoring and evaluation of cosmetic products made in directly consultation with the campus UKSW.

Abstract

Isolation and identification of chemical compounds and antibacterial compounds of the essential oil of Kembang bulan or Japanese sunflower {Tithonia diversifolia (Hemsley) A. Gray} leaves showed that the essential oil contain 29 components. The main components were caryophyllene (27.76%), nerolidol (21.81%),caryophyllene oxide (7.06%), copaene (6.41%) and bicylogermacrene (4.90%). The oil was screened for their antibacterial activity through bioautography method. Two antibacterial spots which had Rf 0.49 and Rf 0.61were obtained. The spot with Rf 0.49 was a mixture of 21 compounds with main compounds were heneicosane, nonacosane and tetratetracontane, while the spot with Rf 0.61 consisted of 22 compounds, which the main compound was nerolidol.

Abstract

Phytochemical screening and Brine Shrimp lethality test of pecut kuda leaf extract had been done against Artemia salina Leach. The aims of this study is to screen potentially bioactive extract of pecut kuda leaf as an effort ti find out the chemical substances responsible for the toxic effect. The Pecut kuda leaves (Stachytarpheta jamaicensis, L. Vahl) was extracted by methanol 80%, then partitioned successively with hexane, chloroform, and ethyl acetate. Phytochemical screening was done according to Ciulei method (1984). The toxicity effect was tested against A. salina, L (Brine Shrimp Test). The result of phytochemical screening known that compounds in the extract of pecut kuda leaves (S. jamaicensis, L. Vahl), hexane fraction contained of sterol and triterpenes; where the chloroform fraction contained of saponin, sterol, and triterpenes; further more the ethyl acetate fraction contained flavonoid, tannin, saponin, sterol, dan triterpenes. The result of the study shows that several fractions of extract of pecut kuda leaves (S. jamaicensis) hexane fraction, chloroform, and ethyl acetate was toxic because it was able to kill more than 50% larva of A. salina, L at the concentration less than 1000 ppm. The LC50 of all fractions of pecut kuda leaves extract (S. jamaicensis, L. Vahl) were shown from the most toxic to the lowest were as followed: LC50 of hexane fraction = 98.33 ppm, of chloroform raction LC50 = 204.17 ppm, and of ethyl acetate fraction LC50 = 249.80 ppm. Finally results of the TLC profile showed that all fraction (hexane, chloroform, and ethyl acetate) indicated that the pecut kuda leaves extract (S. jamaicensis) contained terpenoid compound.

Abstract

ABSTRACTThe objective of the study were to obtain of pumpkin (C. moschata D.) seed oil yield using hexane soxhlet extraction method and the effect of purification on the profile of pumpkin seed oil fatty acids. The results of the study showed that the yield of pumpkin seed crude oil was 37,98% (b/b), whereas the optimum rendement after purification was 76,27% (w/w) by using 0,15% H3PO4. The GC-MS analysis of pumpkin seed oil showed the presence of three same main components of pumpkin seed oil before and after purification which are: linoleic acid, palmitic acid, and stearic acid, respectively. The content of pumpkin seed oil before purification are as follows: 57,96% of linoleic acid, 24,63% of palmitic acid, dan 6,82% of stearic acid, respectively. In the contrary, the content of pumpkin seed oil after purification are as follows: 48,21% of linoleic acid, 20,70% of palmitic acid, dan 5,27% stearic acid, respectively. The purification processes do not affect on the main components of pumpkin seed oil, but determine the difference percentages of pumpkin seed oil main components.

Abstract

This study aims to determine the yield of wild spinach seed oil obtained by continuous extraction methods using Soxhlet apparatus for 10.5 hours in n-hexane solvent, the physio-chemical properties, and the composition of wild spinach seed oil using the Gas Chromatography-Mass Spectrometry (GC-MS) method. Refinement of wild spinach seed oil was done by degumming and neutralization. The yield of wild spinach seed oil extraction before refinement was 4.36 ± 0.29% (w/w) while after refinement was 0.68 ± 0.033% (w/w). Physio-chemical properties of wild spinach seed oil after refinement was as follows: water content 0.37%; peroxide value 9.5 meq/kg; acid value of 0.53 mg KOH/g oil; saponification value 208.9 mg KOH/g oil. The results of GC-MS analysis showed that the wild spinach seeds were composed of 5 main components: dodecanoic acid (0.28%); tetradecanoic acid (0.08%); palmitic acid (1.31%); squalene (94.9%); and linoleic acid (3.34%).

Abstract

Nutritional problems still become a crucial issue in Indonesian public health. Fulfillment of nutritional balance is expected to improve life quality. In humans, one of the nutrients that play a role in the growth of brain and nervous system functions is PUFA, such as omega-6 and omega-3. Besides, fulfillment of nutritional balance can prevent some diseases; especially linoleic acid used to prevent some diseases. Linoleic acid is an omega-6 and essential fatty acid. Linoleic acid is the main essential fatty acid because it is the precursor for GLA, DGLA, and AA. Omega-6 works with omega-3 and some omega-3 benefits are supported or can arise by omega-6 presence. Studies reveal that watermelon contains high linoleic acid. This study aimed to determine the optimum temperature and ratio of fatty acids: urea for the isolation of linoleic acid from watermelon seed oil. The method used was urea inclusion with a variety of temperatures (-6oC, 6oC, 18oC) and the ratio of fatty acid: urea (1:1; 1:3; 1:5). The results showed the optimum watermelon seed oil linoleic acid isolate at 18oC and the ratio of fatty acids: urea 1:5 with linoleic acid purity (%) of 82.53%.

Abstract

Medicinal plants are natural sources of effective antimicrobials from natural products. Tithonia diversifolia (Asteraceae) is a conventional herb that can be used for the treatment of malaria, wounds, and other diseases with biological properties such as antioxidant, antimalarial, antidiabetic, antibacterial, and anti-hyperglycemic. Research on Tithonia diversifolia leaf extract as an antibacterial has been widely carried out. However, its use as a natural antibacterial is rarely studied, especially on flowers and roots. This study aimed to test the antibacterial activity of leaf, flower, and root extracts of the Tithonia diversifolia plant in various solvent fractions. The methods used in this research were Antibacterial Testing with Agar Diffusion and Direct Bioautography Methods, while the solvent fractions used were petroleum ether, chloroform, and ethyl acetate. The results showed that the crude extract of Tithonia diversifolia leaves, flowers, and roots for petroleum ether, chloroform, and ethyl acetate fractions contained antibacterial compounds. They could inhibit the growth of E. coli, P. aeruginosa, S. aureus, and B. subtilis bacteria, with inhibitory activity in chloroform fraction, which was better than in petroleum ether and ethyl acetate fractions. The results of the bioautography test showed that the inhibition was good on gram-positive bacteria with the highest number of spots in the chloroform fraction for the crude leaf and flower extract samples.
