Get PDFLandak regency has potensial natural resources as food sources. The research work aimed to find out types of food planst, food processing, and parts of food planst consumed by Dayak Kanayatn in Pak Mayam village, Ngabang district, Landak regency. The study was conducted from July to September 2016 in Pak Mayam village and Biologi laboratory of Mathematics and Natural Science faculty of Universitas Tanjungpura Pontianak. The research work employed purposive sampling methodology. The result of the research suggested that there are 43 kinds of plants of 26 families consumed as food. The most plant family consumed are Poaceae and Myrtaceae by 9,3%. Part of plants that is eaten is the fruit by 58%. The use of plants consists of five 5 categories; namely vegetables, fruits, spices, root vegetables, and cereal grain. Food plands are prepared without processing by being eaten directly and with processing by boiling, frying, smashing, stir frying, and baking them
Kandungan Pigmen Klorofil, Karotenoid dan Antosianin Daun Caladium
Get PDFCaladium is a family Araceae which has various colors and patterns of leaves. The mechanism of variation of color and pattern on the leaves is caused by the chlorophyll pigment, carotenoid and anthocyanin. Each variation in color and pattern of the leaf has a different anatomical structure. This research aims to find out the differences in the content of the chlorophyll pigment, carotenoid and anthocyanin as well as examine the anatomical structure of the mesophyll in 6 Caladium plants. This research was conducted from January to May 2016. Measurement of chlorophyll, carotenoid and anthocyanin was conducted using a spectrophotometric method while mesophyll tissue anatomy using the method of wet incision preparation. The results showed that the highest chlorophyll content was found in the leaves of C. schomburgkii by 28.508 mg/l, while the highest carotenoid content was found in C. bicolor 1 by 35.780 μmol/g. The highest anthocyanin content was found in C. bicolor cultivar Blaze by 0.057 mg/g. The cross section area of the red, green and white showed a different mesophyll structure. The green area mesophyll tissue differentiates into palisade and spongy tissue containing chlorophyll, while the red and white mostly showed thet mesophyll tissue that did not differentiate into palisade and spongy tissue. The mesophyll cells in the red area contain anthocyanin, and the white area was not pigmented and there was space between the cells among the palisade tissues and between the upper epidermis and mesophyll tissue
Tingkat Kerusakan Hepatosit Mencit yang Diinduksi Alkohol 40%
Get PDFConsumption of alcoholic drink in large quantity can cause alcoholic liver disorder, such as liver weakening, fibrosis and cirrhosis. This research aims to determine the effects of alcohol 40% orally for 20 days and 27 days on the liver of mice. The design of the study is the randomized block design, which consists of three groups: normal control group, exposure to alcohol for 20 days and exposure to alcohol for 27 days. The results showed that adding 40% alcohol for 27 days in mice caused liver damage most severe than alcohol exposure for 20 days. The damage that occured in the liver of mice included narrowing of the sinusoid and changes in normal hepatocyte that became swollen degeneration
Kadar Malondialdehyde Induk dan Struktur Morfologis Fetus Mencit (Mus musculus) yang Diperdengarkan Murottal dan Musik Rock pada Periode Gestasi
Get PDFGestation is a stressful state that involved physiological change. Environmental stressor could alter the adaptive mechanism during gestation, thus bring bad impact to the developing fetus. Music is commonly used as a therapy media to minimize stress during gestation. This research aims to examine the effect of listening murottal and rock music during gestation towards levels of oxidative stress in mouse dams (Mus musculus) and the morphological structure of the fetuses. The levels of oxidative stress were analyzed by measuring malondialdehyde (MDA) level as the biomarker. This research was conducted from July to November 2016 in Zoology Laboratory and Chemical Laboratory of Faculty of Mathematics and Natural Sciences Tanjungpura University Pontianak. Fifteen mice were divided into 2 experimental groups (murottal/M and rock/R) and 1 control group (K). During day 0 to day 15 of gestation, the pregnant mouse dams in group M and R were exposed to murottal and rock music, respectively. Laparatomy was conducted on the 16th day of gestation, followed by serum MDA measurements and observing the fetuses. According to the result, MDA level in group M was significantly lower (0.42±0.21 nmol/mL; p<0.05) than two other groups. This result accompanied by the normal fetuses with highest mean of weight (0.74±0.05 g) and length (18.72±0.90 mm) compared to fetuses from group R and K. Fetus with hemorrhage and intrauterine growth restriction (IUGR) were found in group R, while intrauterine mortality was found in group R and K

Pertumbuhan Kalus Tanaman Markisa (Passiflora sp.) dengan Penambahan Naphtalene Acetic Acid (NAA) dan 6-Benzyl Amino Purine (BAP)
Get PDFPassiflora sp. is one of the herbaceous plants whose leaves contain secondary metabolites. This plant is widely exploited by the community for use as pharmaceuticals. Accordingly another alternative is required to isolate its metabolites and one of the alternatives that can be applied is technique of tissue culture. The purpose of this study is to investigate the effect of NAA, BAP and combination of NAA and BAP on callus growth of Passiflora sp.. This study is conducted in Aloe Vera Center Laboratory of Pontianak. Completely Randomized Design with 4 concentration levels of NAA and BAP specifically 0 M, 10-7 M, 5x10-7 M and 10-6 M was employed 3 times and 48 units of experiments were obtained. The findings indicate that all treatments yield callus with dense texture and generate a variety of color specifically tawny, green and greenish white.NAA, BAP and combination of NAA and BAP has no significant effect on the average time of callus growth. The combination of NAA and BAP has substantial effect on the average of callus wet basis. Concentration of NAA 5x10-7+ BAP 10-6 M and NAA 5x10-7+ BAP 10-7 M produce the highest wet basis in particular 2,4380 g and 2,2420 g. the combination of NAA and BAP has remarkable effect on callus dry basis and concentration of NAA 5x10-7+ BAP 10-6 M produce the highest average of dry basis particularly 0,0160 g
