Abstract

Kelubi lake has an area of ?? 220 ha and high puddles influenced by rainfall. The research aimed to know macrozoobenthos diversity and the quality of Kelubi lake waters. Determination of five sampling stations based on different environmental setting. Macrozoobenthos samples were taken three times at each station by Ekman Grab and identified in the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences of Tanjungpura University Pontianak. Macrozoobenthos research results obtained in the waters of Lake Kelubi four genera namely Chironomus, Dasyhelea, Dixella and Limnodrilus. Value abundance of macrozoobenthos in Lake Kelubi ranged from 44.44 to 355.55 Ind/m2. The diversity index (H) of the highest macrozoobenthos obtained at station IV of 355.55 Ind/m2 and lowest at station I of 0.5004 Ind/m2. The macrozoobenthos diversity in Kelubi lake was low to moderate. The average of evenness index (E) of macrozoobenthos was 0.8650 which indicates high evenness, while the average of Simpson dominance index (C) wason the average of 0,4950 which in considered low dominance of macrozoobenthos. The result of Pearson correlation test shows that depth, temperature, transparency, organic substrate significantly affect the diversity of macrozoobenthos in Kelubi lake. Kelubi lakes classified in moderate pollution levels.

Abstract

Dendropthoe pentandra (L.) Miq constitutes one type of parasite plant, which is efficacious as an antibacterial and able to inhibit the growth of microorganisms. Salmonella typhi is the bacteria that attacks the gastrointestinal tract, so that it is necessary to look for antibacterial alternative medicine from natural materials. The aim of this study is to determine the antibacterial activity of methanol extract from                D. pentandra leaves toward the growth of S. typhi bacteria. The research conducted from August to September 2013. The extract of D. pentandra leaves obtained by employing maceration method. The test of antibacterial activity carried out by using paper disc diffusion method at the level 25%, 50%, 75% and 100% (g/mL) of extract concentration, and also positive control by using 2.5% of chloramphenicol. Phytochemical analysis indicates that the extract of D. pentandra leaves contain flavonoids, alkaloids, polyphenols, steroids and quinones. The analysis indicates that the concentration of  D. pentandra extract leaves has significant effect toward the diameter of the inhibition zone formed. Concentration of 75% is the lowest concentration that can inhibit the growth of S. typhi to grow larger. The results indicate that the methanol extract of D. pentandra leaves has antibacterial activity toward S. typhi.

Abstract

The low fertility and high soil acidity make the peat soils require processing before being used as a medium for plant growth. Peat soil improvement efforts need to be done on an ongoing basis. This study aims to determine the effect and the optimal dose on the using of bokashi straw and petrhikaphos fertilizer on the peanut plant growth (Arachis hypogaea). This study used Factorial Completely Randomized Design (FCRD) with 2 factors namely petrhikaphos fertilizer (A) and bokashi straw (B). Each factor consists of 4 levels, they are: control, 5g; 15g and 25g for petrhikaphos fertilizer and control, 18,75g; 37,5g and 56,25gfor bokashi straw fertilizer. The findings of the research showed that the using of bokashi fertilizer up to 56,25g dosage /plant has not been able to give a noticeable effect on the growth and yield of peanut crop production. Based on those four-dose  treatments which were given, the dose of 25g /kg of seed showed the best result for the parameter root dry weight, number of pods, seeds, seed weight, number of nodules and the total number of effective root nodules. There were no interactions between bokashi and petrhikaphos fertilizer on to all  observations A. hypogaea growth.
