Get PDFThe area of the mangrove forest located in Sebubus Village is not supported by the data and information that provide a description of the forest structure. This research was carried out to find out the vertical and horizontal profile diagram of mangrove vegetation in Sebubus Village, Paloh Sub-district, Sambas Regency, and to find out the influence of the character of environmental factors (salinity, pH, substrate and substrate texture) and mangrove forest zonation patterns. This research was conducted for five months from January to May 2015 in Sebubus Village, Paloh Sub-district, Sambas Regency. The data was collected by making transects at three points. The transects were 30x10 meters in size. Each transect had a sub-plot with the size of 10x10 meters. The observations and measurements were conducted on the identification of tree species, tree height, stem diameter, canopy width, and distance between each tree. The soil samples were taken in each sub-plot to conduct the analysis of the pH value, salinity and substrate structure. The research revealed that the mangrove species found in the site were Brugueira cylindrica (L.) Bl., Brugueira gymnorhiza (L.) Lam., Rhizopora mucronata Lam. and Sonneratia alba Sm.. The zonation patterns formed from the coast to inland were Sonneratia alba Sm., Rhizopora mucronata Lam., Brugueira cylindrica (L.) Bl., and Brugueira gymnorhiza (L.) Lam.. The trees found can be categorized into 3 strata, i.e. 4-9 m, 10-15 m and 16-21 m

Get PDFLotus (Nelumbo nucifera Gaertn) is an aquatic plant that contains various kinds of phytocemical compounds, one of which is quercetin that has the potentiality to suppress inflammation. The arm of this research was to observe the anti-inflamation effect of Lotus infused water on kidneys mikroanatomical structure of mice (Mus musculus). The test subjects used in this research were 2 months old male swiss strain mice. This research utilized the completely randomized design (CRD) with 5 treatments and 3 replication each. The treatments groups were the given Lotus infused water orally consist of 5,6 mg/g BW, 8,4 mg/g BW and 11,2 mg/g BW dosages for 7 days, the normal control groups and the negatif control groups. Kidney microanatomical preparations were made using paraffin method with HE coloring. The result of this research show this research shows that stressing the mice may affect their kidneys microanatomical structure in forms of cell swelling (edema), hidropic degenerations, necrosis, and atrophy. The consumtions of Lotus infused water can suppress the inflammation on kidneys mikroanatomical structure of mice. The changes on kidneys tubulus and glomerolus of mice may start to be visible on the consumtion of 5,6 mg/g BW dosage of infused water

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)
Struktur Anatomi Daun, Kantung dan Sulur Nepenthes gracilis Korth. yang Tumbuh di Area Intensitas Cahaya Berbeda
Get PDFSunlight is one factor that plays a major role in the process of the plant physiology. Plants will go through a variety of morphological and anatomical changes in order to be able to adapt to the environment with varying light intensity. This research aims to know the anatomical structure of leaves, foliage and Nepenthes gracilis Korth. tendrils which grow in areas with different light intensity. The research was conducted from May 2014 to September 2014. The paraffin method is used inmaking preparations of transverse incision of leaves, foliage, and N. gracilis tendrils. The results of the study on the transverse incision of the leaves, foliage and tendrils growing at different light intensity indicated a difference in the thickness of the epidermis, stomata number, thickness of cortical cell layers and size of the vessel. N. gracilis that were grown in the shaded area had thinner epidermal thickness of leaf which was 3.24 ± 0,48μm than those grown in an open area which was 6.59 ± 1,35μm. The number of stomata grown in a shaded area was fewer i.e. 44 compared to that grown in the open area which was 84. The thickness of the cortical cell layers of tendrils grown in the shaded area was thinner which was 155.30 ± 2.79 μm than those grown in an open area that was 176, 49 ± 4,23μm and the size of the vessel on the leaves and tendrils grown in the shaded area was smaller than those grown in an open area
