A Simple and Practical Method for Rat Epididymal Sperm Count (Rattus norvegicus) Muhammad Ja’far Luthfi
Biology, Medicine, & Natural Product Chemistry Vol 4, No 1 (2015)
Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Sperm sample from epididymal source can be determined its number using minimal amount of equipment. These method will aid researcher and practitioner in sperm quality analysis to determined sperm number rapidly and practically.

The Effect Of Intensive Keramba On The Presence Of Parasite Organisms In Rivers Of Lingsar Area Supriadi Supriadi; Maratun Janah

The application of intensive keramba in rivers could affect the presence of parasite organisms throughout the river downstream. The aims of this research are to find out the diversity of parasite species and the effect of intensive aquaculture method developed by the community on the presence of various parasitic organisms, particularly in the downstream area. A total of 65 Tilapia fish samples (O. niloticus) that was collected from 3 areas ( 15 samples from upstream, 25 samples in keramba and 25 samples from downstream areas) have been examined in the laboratory of Faculty of Mathematic and Natural Science, University of Mataram. Methods employed to identify parasites that infected fish samples are native method and flotation method. This research has identified 7 species of parasites which were divided into 2 groups: ectoparasites (Trichodina sp., Amylodinium sp., Oogonium sp., Dactylogirus sp., Trematode) and endoparasites (Entamoeba sp. dan Camallanus sp.). Diversity index calculation indicated that parasite organisms in upstream area were lower in number than that in the downstream and intensive karamba area (H’= (0,825; 1,596 dan 1.324 respectively). These data has showed there was a difference in species diversity and evenness index of parasite organisms in the upstream, downstream and intensive keramba area. In conclusion, there was significant influence of the application of intensive keramba on the appearance of various parasite organisms that could affect the sustainability of fish aquaculture.

Krokot Extract (Portulaca Oleracea. L) as Natural Light-harvesting pigments for Dye-Sensitized Solar Cells (DSSCs) : Influence of Dye Acidity Cici Nurfaizah; Didik Krisdiyanto; Khamidinal Khamidinal; Sudarlin Sudarlin

Dye-sensitized solar cells (DSSCs) was fabricated using natural dyes extracted from krokot (Portulaca Oleracea. L). The effect of dye acidity was investigated on natural pH extract, 5.00, 4.00 and 3.00 of pH. The efficiency and stability DSSCs as a function of the dye acidity was studied. The result of the UV-Vis shows that the absorption of wave-length from dye extract of krokot is located in the visible region with the absorbance peak in 410.5 nm and 664.5 nm which are the peak of chlorophyll. The efficiency of extract krokot dye sensitized solar cells was decreasing 6.88 x 10-3 % to 0.42 x 10-3 % when pH of the dye was adjusted from 6.27 to 3.00. DSSCs stability was also decreased look for efficiency loss from 5.27% to 97.49% in the same conditions.

The Phytoestrogenic Potential of Yam Bean (Pachyrhizus erosus) on Ovarian and Uterine Tissue Structure of Premenopausal Mice Cicilia Novi Primiani

Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

The use of estrogen hormone by public has significantly been improved either as prevention or treatment of disease. Menopausal issues in women are often treated using hormone replacement therapy. In regard to this, yam bean is found to contain genistein and daidzein compounds with a chemical structure that resembles estrogen hormone, therefore yam bean is categorized in the phytoestrogen group. The purpose of this study was to identify the potential of yam bean on ovarian and uterine histology of mice. This research employed a Completely Randomized Design of experimental research approach of one factor namely yam bean in three different dosage treatment: 0.3 g/kg, 0.6 g/kg, and 0.9 g/kg of yam bean for 24 days. The surgery and organ harvesting of ovary and uterus were conducted on Day 25 along with the making of histological preparat using paraffin method and Hematoxylin-eosin (HE) staining. The data was then analyzed descriptively. This research found that there were both secondary and tertiary follicle proliferation as the antrum contains some estrogen level. Meanwhile, the endometrial tissue of the uterus experienced uterine glandular proliferation. To conclude, yam bean was found to be a natural estrogen source.
