Abstract

Population characteristics is one of the efforts made to determine the presence of Hipposideros cervinus in a particularhabitat. This study aims to investigate the population characteristics of H. cervinus and physical characteristics ofBratus cave in Air Besar District, Landak Regency. The study was conducted by using Capture Mark Release Recapture method. Bats were caught in the web were marked with red oil paint on their digiti then released and recaptured again after 24 hours. The morphometrics of H. cervinus measured in this study are body length, wing span length, forearm length, fibula length, ears length, tail length, tarsometatarsus length, tarsometatarsus diameter, hind legs length without claws, hind legs length with the longest claws. The results show that the population of H. cervinus in the Cave of Bratus is 120 ind. Total number of H. cervinus found are 54 individuali consisted of 18 males and 36females with sex ratio of 1: 2. The temperature, humidity, light intensity, and wind speed at the Cave of Bratus ranging from 26o to 27oC, 87-94%, 8-12 lux, and 0 m/s respectively. Hence, environmental characteristics of the Cave of Bratus are suitable as habitat of H.cervinus.

Abstract

High levels of salt in the soil may cause the disruption of plant growth, especially the crops. Mustard greens (Brassica juncea L.) as the main vegetable commodity in West Kalimantan, is grown on soil with normally salinity level. The purpose of this research was to determine the growth response of mustard greens (B. juncea) against the exposure to the NaCl. The research was carried out from August to Oktober 2014. Research was carried out using the Completely Randomized Design (CRD), consisting of six treatment concentrations of NaCl i.e., 0 ppm, 2,000ppm; 4,000 ppm; 6,000 ppm; 8,000 ppm; 10,000 ppm respectively. The results showed real effects of the treatment onthe leaf area, length of the root, wet and dry weight, but had no real effect on the parameter of the number of chlorophyll. The whole treatment began to to affect the growth of mustard greens on the concentration of 4,000 ppm of NaCl. The range of tolerance of mustard green toward NaCl salt concentration was between 2,000 ppm – 10,000 ppm of NaCl.

Abstract

Spot and rust disease is a disease that most often attacks the leaves of the maize plant (Zea mays L.) Both of these diseases are caused by a different type of fungus infection that causes different symptoms. Symptoms of the disease, indicated by morphological change of the anatomical structure. This research is aimed at determining the anatomical structure of leaves of maize (Zea mays L.) infected with the spot and rust disease. The research was carried out from April to September 2014. The paraffin method is used in making preparations of transverse incision of leaves (Zea mays L.) that were stricken with the spot and rust disease. The result of the study showed a thickening of the epidermis tissue, increase in mesophyll cells and decrease in xylem diameter of transverse incision on the leaves of maized infected with spot and rust disease. The rust disease caused most severe damage on the mesophyll and vessel tissue.

Abstract

Candida albicans is a fungus which commonly found in the human body and can cause candidiasis disease with varies symptoms. One of the potential anti fungal plant is Mikania micrantha Kunth leaves. The purpose of this study was to determine the ability of M. micrantha fungus. The anti fungal activity tests on M. micrantha leaves were conducted by using Kirby-Bauer smear method. The test were carried out with 7 treatments, ie : negative control, solvent control (DMSO 10%), posiive control (ketokonazole 2%), concentrate of M. micrantha leaves extract as much as 20%, 25%, 30%, 35% and 40%. From the result on 30% anti fungal concetration, it showed that the activity level was very strong. This case shows that 30% concentrate of M. micrantha leaves extract is the most potential concentrate to inhibit the growth of C.albicans fungus.

Abstract

The growth rate of banana (M. paradisiaca L. var. nipah) in three types of soil in Pontianak district is very high. The plant growth is expected to be affected by vesicular arbuscular mycorrhiza’s activity, a type of fungus that helps the process of growth and absorption of nutrients from its surroundings. This study aims todetermine the Genus found in vesicular arbuscular mycorrhiza and percentage of infection level in three types of soil planted with banana (M. paradisiaca L. var. nipah). This study was carried out for three months from April 2014 to June 2014 in Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences,University of Tanjungpura. The procedure in this study consisted of several stages, namely sampling, isolation of spores with combination method, pour-wet filter technique and centrifugation technique, identification and characterization, as well as coloring and making root preparations with method of coloring. Based on observation result at Genus spores of vesicular arbuscular mycorrhiza in alluvial soil, Acaulospora, Archaeospora, Gigaspora, Glomus and Paraglomus were found. Genus spores of vesicular arbuscular mycorrhiza can be found in peat soil that contained Archaeospora, Gigaspora, Glomus, Paraglomus and Scutellospora. In ultisol soil, Genus spores of vesicular arbuscular mycorrhiza consisted of Acaulospora, Gigaspora, Glomus and Paraglomus. Observation result on vesicular arbuscular mycorrhiza indicated that the percentage of infection in alluvial soil was 53% (high), 41% (average) in peat soil and ultisol soilamounted 57% (high).
