Abstract

Research on the diversity of ferns in the forests of Tumbang Manggu, Sub-district Sanaman Mantikei, Central Kalimantan, has been done. The study was conducted in March – April 2016  by using explorative methods. The results show, at least 28 species of ferns were found in the forest area, of which 16 species are terrestrial ferns and 12 species of epiphytic ferns. These species are included in 22 genera and 14 families. Huperzia and Pyrrosia are most abundant, each genus were consists of 3 species. The most rich families in term number of species are Polypodiaceae and Lycopodiaceae, with 6 species and 4 species respectively. Abundance of each species in the region was different, Blechnum orientale L., Dicranopteris linearis (Burm. f.) Underw., Lycopodiella cernua (L.) Pic. Serm., and Vittaria scolopendrina (Bory) Schkuhr ex Thwaites were found in large quantities and spread almost all over the region. Asplenium nidus L., Drynaria quercifolia (L.) J. Sm., Stenochlaena palustris (Burm. f.) Bedd., Lygodium circinatum (Burm. f.) Sw., Pyrrosia lanceolata (L.) Farw., Nephrolepis falcata (Cav.) C. Chr. and Vittaria ensiformis Sw. were found in considerable numbers. Asplenium pellucidum Lam., Athyrium bantamense Milde, Helminthostachys zeylanica (L.) Hook. and Tectaria crenata Cav. were found in small quantities and only in certain places. Local communities around the region have not much utilizing the ferns yet.

Abstract

The existence of orchids is often threatened with extinction that can be caused by natural damage. In addition, the continuous harvesting of orchids from nature without considering its sustainability can threaten the extinction of orchids in a region. There is a need for knowledge about the diversity of orchids so that it can be the basis of conservation in a region specifically nature reserve and Nature Park Bogor. Research using transect methods and data collection conducted using field observation techniques. The observation area consists of three locations altitude: 1400, 1500 and 1600 m above sea level . There are 27 species of orchids consisting of 19 genera. From the calculation of important value index (INP), the dominating type is found at altitude 1400 and 1500 m above sea level is Ceratostylis crassifolia, While at height and 1600 m DPL is Liparis compressa. Index diversity of type in the research site with a height of 1400 m DPL is moderate and at an altitude of 1500 and 1600 m DPL is high. The spread index is known that the pattern of spreading orchid species in three research locations has a clumped group spread pattern.

Abstract

The purpose of this research is to know the quality of diluent which is stored at room temperature and temperature of preservation to survival of spermatozoa, to know the temperature of cement storage to survival of spermatozoa and to know the type of cement diluent material to survival of spermatozoa. The study used local sheep cement. The design used was Randomized Block Design (RAK) Factorial pattern with 2 treatment of storage temperature ie S1 = room temperature; S2 = preservation temperature; and with 4 diluent treatment: P1 = yolk citrate; P2 = skim milk; P3 = liquid milk; P4 = tris of soybeans. The observed variables were the macroscopic and microscopic cement quality prior to dilution, the progressive movement of sperm from each diluent and the progressive movement of sperm at each storage temperature. The administration of yolk citrate diluents affects the survival of spermatozoa compared with other diluents (P 0.05). The preservation temperature gives optimum results in suppressing the rate of decline in survival of spermatozoa (P 0.05). Giving yolk citrate stored at a preservation temperature is apparent in maintaining the survival of spermatozoa with 55% motility for three days.Keywords: survival, spermatozoa, cement diluents, storage temperature

Abstract

Drilling natural gas contains water vapor (H2O) and contaminant gases such as CO2 and H2S which must be removed because it reduced the calorie value of the product. H2S gas is also corrosive, easily damaging equipment so that it increased maintenance costs. The process of removing CO2 and H2S gas uses MDEA (methyl diethanolamine). This study aims to determine the optimal concentration and flow rate of absorbent methyl diethanolamine (MDEA) to absorb H2S in the plant I gas flow in Energy Equity Epic (Sengkang) Pty.Ltd. The study was carried out with a steady MDEA mix absorbent flow rate (50% pure amine and 50% demineralization water) fixed at 13 US Gallons per minute flowing continuously at the upper absorber inlet, sour gas flow rate, at the bottom of the absorber inlet with variations in the flow gas namely 7,9,11,13,15,17 MMSCFD and is contacted with amine solution counter-current. Purified natural gas (sweet gas) produced from the top absorber column outlet with an H2S content below 10 ppm. The results showed that the greater the flow rate of gas inlet, the greater the acid gas absorbed. The  amount  of gas  entering and  exiting gas follows the  equation        y = 0.003 x - 2.2537. The ability of the amine solution to absorb H2S follows the logarithmic equation y = 0.167 ln (x) + 101.02 with a value of R = 0.9857, y is H2S absorbed by the amine solution and x is the H2S rate.

Abstract

Anura includes frogs and toads, playing an important role as ecosystem quality bioindicators, as well as insect population control. Anura is very sensitive to changes in the environment, since its egg stadium. Disruption to its natural habitat, can threaten Anura's survival. This research is done in the Nature reserve area and Telaga Warna Natural Nature Park. Observations using the Visual Encounter Survey (VES) method. Analyses conducted include the calculation of the species diversity index of Shannon-Wienner, the frequency of species meetings, and the density of species. The results of the research gained 11 species of Anura from 5 families, namely Megophryidae, Microhylidae, Ranidae, Dicroglossidae, and Rhacoporidae. The level of diversity of Anura species in the research site is moderate (H ' = 0.152). Density ranged from 0.07 to 0.24 tails/m2, and the highest density is demonstrated by the Rhacophorus margaritifer. The frequency of meetings at a sampling location ranges from 0.01 to 3.6%, with the highest frequency being Rana chalconota. Generally, the quality of the ecosystem of Telaga Warna is good, especially in the area of Gayung Swamp

Abstract

Trichopyton mentagrophytes is a type of fungus that belongs to a group of dermatophytes, and a disease that causes dermatophytosis (ringworm), this fungus likes parts that contain keratin substances such as skin, hair / hair, nails or horns. This study aims to determine the antifungal activity of 50% and 96% ethanol extract. KHM testing was made with a concentration of 2.5%, 5%, 7.5% and 10% with the dilution method to determine KHM. Whereas in testing the width of the inhibitory area (LDH) was carried out after getting the MIC value at concentrations of 10%, 25% and 50% with disc diffusion method to determine the effective LDH and qualitative phytochemical testing. The results showed that 96% ethanol solvent at a concentration of 50% could inhibit the fungus Trichopyton mentagrophytes compared to 50% ethanol as seen from the inhibition zone formed in the width of the inhibitory area. Secondary metabolite compounds found in 50% ethanol extract and 96% ethanol are flavonoids, alkaloids, saponins, tannins, quinones and terpenoids.
