Abstract

The low participation of men in Family Planning Program is caused by the limited choices of contraception for men. The purpose of this research is to find out the effects of secang woods extract on the spermatozoa viability of male mice, it is expected that some day secang wood could be formulated into components of oral contraception for male.        Thirty male mice weigh 25-30 g of 2,5 month old are grouped using Complete Random Design (RAL) factorial patterned 2x5 witn n=3. The extract of secang wood is made as ethanol extract, chloroform and water fraction each with 50 mg/25 g weight and given 1 ml orally each day. The analysis of the spermatozoa viability is conducted by supravital painting. The observation of preparation is done by 400x magnification. The living spermatozoa are colorless and the dead ones are red. The observation is conducted twice. Ten days after the extract is given (to identify the changes) and ten days after the extraααct is stopped (to see the recovery of spermatozoa). The gathered data is tested using Anava  (α   = 0,05) and DMRT   (α  = 0,05).  The result shows that the extract of secang wood can lower the viability of mice spermatozoa.

Abstract

Dayak Bukit community in Loksado has a long history of usage of various kinds of plants in their daily living, either as food, medicine, or in rituals. In the present study ethnobotanic investigations were performed on jalukap plant (Centella asiatica L) to document the use of the plant by people of Loksado. Botanical study revealed that the plant has simpodial branching, single foliation, indefinite composite inflorescence, composite fruit, and fibrous root. Ethnopharmacological study documented the use of the plant for fish poisoning, as well as for wound and bleeding cough medication. Ethnoanthropologically people use the plant in a ritual against flood disaster. Ethnoeconomic study revealed low economic value of the plant as Loksado people use it only within the community. Ethnolinguistic study documented that the name ‘jalukap’ originated from the form of the leaves which resembles human palm; in Banjarese the word ‘jalukap’ means palm.

Abstract

The objective of this study was to investigate the total content of two omega 6 fatty acids, namely linoleic acid (LA, C18:2n-6) and arachidonic acid (ARA, C20:4n-6), of mole crabs Emerita talpoida and E. Analoga. Samples of mole crabs were collected from intertidal zone of Yogyakarta’s south coast. The omega 6 fatty acids were prepared by in situ transesterification method, and were analyzed by gas chromatography. This study revealed that omega 6 fatty acid of E. talpoida consisted of 9.9% LA and 1.90% ARA, while that of E. analoga consisted of 11.11% LA and 1.83% ARA. It was concluded that the total content of omega 6 fatty acid of E. analoga was higher then that of E. talpoida.

Abstract

Density and biodiversity of soil nematodes at different depths of peat soil were studied in search for optimum depth of soil samples taken for nematode community data. Soil samples were taken from a natural peat land at Gambut Subdistrict, Banjar District, the Province of South Kalimantan, and were separated into 0-5 cm, 5-10 cm, and 10-15 depth groups. Soil nematode density and number of species were recorded along with soil pH, water content, and total-N content. Nematode biodiversity was estimated by sample-based and individual-based species accumulation curves and Shannon-Wiener diversity index. It was demonstrated that 5-10 cm was the optimum depth of soil samples for nematode biodiversity in the study area, despite insignificant difference between 0-5 cm and 5-10 cm in nematode densities. The results suggested that soil samples for nematode community data in peat soils could be taken up to 10 cm deep. It was also demonstrated that ten samples and one thousand individual nematodes were sufficient to obtain representative data on nematode biodiversity in the study area.

Abstract

East Kalimantan is an area rich in banana germ plasm. Conservation should be focused not only on varieties of high economic values, but on those of unknown economic value as well. Studies on genetic, morphological, anatomical, and agronomical characters of plants are required to avoid duplications of germ plasm collections. In the present study six banana germ plasm accessions - AK1M, AK2M, AK3M, AK4M, AK7P and AK8P - from East Kalimantan were examined. The objective was to reveal the ploidy based on chromosome numbers and to characterize the anatomy of the stomata. Chromosome analysis revealed different ploidies: diploid and triploid, with chromosome number 2n=22 for accessions AK1M, AK2M, AK3M, AK4B, and AK7P, and 2n=33 for accession AK8P. There was a correlation between the sizes of the epidermal cell and the stomata. Accession AK8P with triploidy had bigger epidermal cells and stomatas. The stomatas were located on the upper and lower surfaces of leaves with the exception of acccession AK4B whose stomata were located only on the lower surface. The highest stomatal density on the upper surface (3227.18 /mm2) was shown by accession AK3M with stomatal index value of 6.44%, while the highest value on the lower surface (17222.22/mm2) was found on accession AK4B with stomatal index of 15.35%.
