Abstract

Longan plants (Dimocarpus logan L.) are generally used by the community only for their fruit. Longan leaves contain secondary metabolites such as flavonoids, polyphenols, saponins, and tannins. Flavonoids are polyphenolic compounds and have antioxidant properties that are not heat-resistant, therefore a suitable method is needed for extracting flavonoids, especially methods that do not use heat. Maceration extraction method is an extraction method by immersing simplicia at room temperature, while the Microwave Assisted Extraction (MAE) extraction method is an extraction method using microwave radiation. The study aims to determine the most effective method for flavonoid content of longan leaves using 2 extraction methods, namely maceration and MAE. Determination of flavonoid content was done using Aluminium chloride reagent whose absoption was measured using UV-Vis spectrophotometry. The results showed that the best extraction method to produce the highest flavonoid content in 70% ethanol extract of longan leaves was the Microwace Assisted Extraction method which produced flavonoid levels of 1.32 ± 0,09%.

Abstract

This research was aimed to create aromatic candle, infused with cinnamon (Cinnamomum burmanii) bark essential oil, which is a potential repellant for house fly (Musca domestica).  The distillation of akar wangi samples was carried out at the Spice and Aromatic Research Unit by vapor distillation method for 9-12 hours. The aromatic candles were based on a mixture of solid paraffin and stearin in a 2:8 proportion, respectively, enriched with fragrant root bark essential oils with 5 formulas, namely F1 (placebo), F2 (fixative), F3 (1% essential oil), F4 (2% essential oil), and F5 (3% essential oil).  The repellency test was carried out by inserting 20 house flies in a of 50x50x50 cm container that contains a lighted aromatic candle according to the doses mentioned above, and shrimp scalps located 15 cm from the candle that functions as a bait. The calculated parameters were the hourly number of flies that were allured to the bait for 6 hours, which were related to the candles repellency and the house flys preference of candle. The repulsion ability result were 89.724%, 75.28%, 68.06%, 49.17%, 9.72% for F5, F4, F3, F2, and F1, respectively. The result also showed that the F4 sample was the most preferred sample.

Abstract

Aquaculture of nilem fish needs parent and larvae. The good parent is available from research station with good facilities and management, so it can distribute to farmer by transportation. The important factors that should be notice in transportation process is usage of anaesthetic ingredients to exhilarate fish during transportation process. This research was used nutmeg bean oil contained of miristisin that able to exhilarate. The result of main research showed that the more nutmeg bean oil concentration the more fast nilem fish will be insensible, the lowest concentration (75 mg/l) sensible time of 97,11 minutes while the highest concentration (150 mg/l) showed insensible time of 10,13 minutes. The result of conscious time observation showed that 75 mg/l  resulted conscious time of 17,5 second while 150 mg/l resulted concious time of 740 second. 150 mg/l concentration is the best concentration because it has the fastest insensible time of 10,13 minutes, the longest concious time of 740 second, has hatch value degree and the longest larvae-life and  effective for exhilarate nilem fish. Nutmeg bean oil has influence towards sperm quality, but all of the treatments have the same effect (not significant) towards sperm quality, egg-impregnation degree, egg hatch and nilem fish larvae-life.  Keywords:  nutmeg bean oil,  anaesthetic ingredients in delivery process,  spermatozoa quality for spawning, nilem fish

Abstract

Menopause is a condition in which menstrual cycles stalled due to gland gonadotropin no longer carry out their duties in work affecting the ovaries to produce estrogen. Will halt production of estrogen can lead to osteoporosis (bone loss), kolesterolemia and heart disease. Basil herbs contain chemicals suspected of having estrogenic activity. This study aims to determine the optimum dose estrogenic activity and n-hexane extractof herbs basil (Ocimum americanum L.). animal testing is used 25 female rats were divided into 5 treatment groups. The result showed that all three doses of n-hexane extract of basil herbs have estrogenic activity. The average increase in estrous cycle in groups III, IV and V was 143 hours, 144,6 hours, and 148,6 hours, while the average of scoring against ovarian and uterine vascularitation in group III, IV and V are 2,2; 2 and 2,4. In weighing the ovaries and uterus weights on average in groups III, IV and V are 1,36 g, 1,72 g and 1,7 g. From the above result it can be oncluded that n-hexane extracts of basil herb can cause estrogenic activity with an effective dose of 0,2 g/200g BW. Key words: Basil (Ocimum americanum L.), estrogen wung, n-Heksan
