Abstract

The 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.

Abstract

The mycorrhiza is a microorganism which is symbiotic with plant roots, in which it helps plants to absorb nutrients. The mycorrhiza had no effect on fertile soil, but plays an active role in the less fertile soil, one of which is peat soil. Based on its level of ripening, peat soil can be divided into three categories, i.e. sapric, hemic and fibric. This research was conducted to find out the types of spores of vesicular arbuscular mycorrhiza (VAM) and the density of VAM spores at three levels of peat ripening in the area of Gunung Ambawang protected forest in Kubu Raya Regency. This research was conducted for six months from November 2014 to April 2015 in the Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences of Tanjungpura University. The soil sample was taken in the area of Gunung Ambawang protected forest and the analysis of soil chemical content was carried out in the Laboratory of Chemistry and SoilFertility, Faculty of Agriculture of Tanjungpura University. The isolation of spores was done through a combined method of wet-sieving technique and centrifugation technique. The results indicated that the spores found consisted of 6 genera i.e. Acaulospora, Archaeospora, Gigaspora, Glomus, Paraglomus andSclerocystis. The spore density was the highest in sapric peat with 558 spores, medium density in hemic peat with 514 spores, and the lowest density in fibric peat with 393 spores.

Abstract

Research on the effect of media composition for the growth of stem cuttings Nepenthes (Nepenthes gracilis Korth.) has been done in Nepenthes captivity Pontianak, Faculty of Mathematics and Natural Scienses and in Chemistry and Soil Fertility Laboratory of the Faculty of Agriculture, University of Tanjungpura in November 2013 until January 2014. This research to determine the effect of planting media composition on the growth of stem cuttings Nepenthes gracilis. This research uses a completely randomized design (CRD) with 7 treatments and 3 replications, as treatments in this experiment is the planting media composition Moss (M0), Moss + Compost (M1), Moss + Coconut Fiber Powder (M2), Moss + Charcoal hust (M3), Moss + Compost + Coconut Fiber Powder (M4), Moss + Compost + Charcoal Husk (M5) and Lumut + Coconut Fiber Powder + Charcoal Husk (M6). Parameters measured were plant height, root length, number of leaves, shoot number, number of bags and wet weight. The results showed that the composition of the planting medium significantly different to the length and number of pockets. The best planting medium composition on the growth of root length Nepenthes gracilis is Lumut + Coconut Fiber Powder + charcoal husk and the best media composition to the amount of bags of Nepenthes gracilis is Lumut + Coconut Fiber Powder. The Effect of media composition was not significantly different planting on plant height, leaf number, number of buds and wet weight

Abstract

The aim of this research was to cognize capability of cellulolytic bacteria isolated from peat soil in degradation cornhusk waste. The research was conducted from March to April 2014. The celluloytic bacteria used in this research were Acetobacter (Ab), Acidomonas (Ad), and Cellvibrio (Cv). This research utilized Completely Randomized Design (CRD) consist of 5 treatments, which were treatment A (control), B {2g of cornhusk with 10% bacterial liquid culture (2.6ml Cv and 2.6ml Ad) added}, C {2g of cornhusk with 10% bacterial liquid culture (2.6ml Ad and 2.6ml Ab) added}, D {2g of cornhusk with 10% bacterial liquid culture (2.6ml Cv and 2.6ml Ab) added}, and E {2g of cornhusk with 10% bacterial liquid culture (1.8ml Cv, 1.8ml Ab, and 1.8ml Ad) added}. The combination of Cellvibrio, Acidomonas, and Acetobacter bacteria on each treatment were capable of decomposing the cornhusk waste with decrease in the substrateweight about 19,3-21,63%, with 2.452-2,965% protein contents, 1.254-1.864% fat contents, and 3.176-4.543% carbohydrate contents. The combination of Cellvibrio and Acetobacter bacteria were faster than the other combinations in decomposing the corn husk waste measured by substrate decomposition rate valuewhich was 3.090% in 7 days.

Abstract

West Kalimantan is rich with various kinds of plants that can serve as medicine and the province is inhabited by various tribes. The largest tribe in Kalimantan is the Dayak. One of the tribes found in West Kalimantan is the Jangkang Tanjung Dayak who still use traditional medicine. This research aims to identify the types, parts and the preparation method of plants used as medicine by the Jangkang Tanjung Dayak Tribe in Ribau Village. The research was carried out from September to November 2014 in Ribau Village, Kapuas Sub-district, Sanggau Regency, West Kalimantan, and at the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, University of Tanjungpura Pontianak by using the snowball method and semi-structured interviews. The results of the research discovered 65 species of medicinal plants belonging to 38 families. The most widely used family is the Euphorbiaceae, i.e. as many as 7 species. The most widely used parts of the plant is the leaf, i.e. 50% .The most widely used preparation method is boiling i.e. 48.59%. The habitat of medicinal plants found in the vicinity of the forest is at a percentage of 44.68%.
