Indonesia has at least 47 types of ecosystems, one of ecosystems that have a lot of potential in Indonesia is a mangrove forest. Mangrove forests in Indonesia have a high diversity of flora and fauna. Development and utilization of coastal areas around the mangrove forest, usually not done wisely that is likely to endanger the stability of the mangrove ecosystem in the long term.

One alternative utilization of mangrove forests that could be developed without damaging the environment is the development of ecotourism. Mangrove forest in Pancer Cengkrong Karanggandu is one of the mangrove forest areas with the potential to be developed into a tourist area of mangrove.

The purpose of this research is to study the potential and preferences of flora and fauna (birds) in the Cengkrong Mangrove Forest as a tourist attraction in the development ecotourism programs with community participation. Stakeholders involved in the study consisted of mangrove forest communities, students of nature lovers and a science teacher with a total of 135 people. Data analysis was performed with the help of Microsoft Excel and analyzed descriptively further showed form of graphs.

Result showed that Cengkrong mangrove forests has the potential to be used as ecotourism. Diversity of flora found in the mangrove forest is composed of 22 species with the highest RFC index is Brugueira gymnoriza. While the diversity of bird species found to consist of 21 species with the highest RFC index is Laptoptilus javanicus.

Effects of tropical legume cover crops on soil quality at dryland farming area in Bali, Indonesia

Two field experiments were conducted to study the effects of tropical legume cover crops on soil quality in dryland farming areas at Angantaka village, Badung regency, Bali Province of Indonesia from June to November 2013. In the first experiment, three tropical legume cover crops (LCC) (Centrosema pubescens L.(Cp), Mucuna pruriens L.(Mp) and Pueraria javanica L. (Pj)) and one control (without LCC) were arranged in a randomized complete block design with four replicates.

Variables measured were the quality of LCC biomass, C-absorbed and fixed-N by LCC. The LCCs were harvested after three months, which were then incorporated into the soil according to the treatments set for the second experiment. Design for the second experiment was a Split-plot with four replicates, where residues (biomass) of three LCC (results of the first experiment) were assigned as the main plot and four times of biomas incorporation (0,10, 20 and 30 days) as the subplot. Results showed that Pj was the best LCC crop among others (Cp and Mp) due to its highest quality. Pj also had the highest absorbed-carbon (58.50 t ha-1), fixed-N (490.21 kg ha-1), biomass FW and DW (304.83 and 116.99 t ha-1) among LCC species.

The treatment of Pj with 30 days biomass incorporation significantly improved the soil quality as indicated by the highest soil moisture content (40.25%) and porosity (79.90%), organic-C (1.95%), total N (0.09%), available-P (15.71 mg kg-1), exchangeable-K (2.07 mg kg-1) and soil respiration (63.94 meC-CO2 kg-1day-1).

The effects of using canola oil with vitamin E on performance and carcass traits of broilers | JBES

This experiment was conducted to investigate the effects of using canola oil with vitamin E on carcass traits of broilers. This study was carried out as 3×2 factorial experiment with 3 levels of canola oil (control, 2.00 and 4.00 percent) and 2 levels of vitamin E (0 and 150 mg/kg) in 6 treatments, 3 replicates and 14 birds in each replicate in a completely randomized design.

In this experiment 252 day old broiler chicks were used for 42 days. Inclusion canola oil until 4% did not have any significant effects on performance of broilers (P>0.05). Inclusion 150 mg/kg vitamin E significantly affected the performance of broilers. The lowest amounts of daily weight gain (39.38g), daily feed intake (85.91g) and the highest ratio of feed conversion (2.19) were resulted by inclusion 150 mg/kg vitamin E. Inclusion 150 mg/kg vitamin E significantly affected the carcass traits of broilers. The lowest carcass (68.04%) and abdominal fat (2.76%) and the highest liver (4.12%) percents were resulted by inclusion 150 mg/kg vitamin E. As interactive effects; the lowest carcass percent (63.98%) were obtained by adding 4% of canola oil and 150 mg/kg vitamin E to broiler diets.

Determination of phosphate solubilization and plant growth promotion of bacterial isolates from paddy rhizosphere | IJAAR

A study investigating bacterial isolates having inorganic phosphate solubilization along with plant growth promoting abilities was attempted. The isolates were from different paddy rhizosphere soil samples of Salem region. A total number of 34 bacillary isolates were successfully isolated from 315 morphologically distinct colonies and evaluated for their ‘P’ solubilization ability. The colonies showing clear halo zones (≥ 2mm) around them, on the Pikovskaya agar medium containing Tri-calcium Phosphate (TCP) were selected as phosphate solubilizers. Among these isolates 11 strains (BMERF-PSB3, BMERF-PSB4, BMERF-PSB7, BMERF-PSB8, BMERF-PSB12, BMERF-PSB14, BMERF-PSB16, BMERF-PSB19, BMERF-PSB20, BMERF-PSB23 and BMERF-PSB25) had shown superior (≥ 5-29 mm) phosphate solubilization ability. Among these 11 superior (32%) PSB isolates, 4 (12%) (BMERF-PSB3, BMERF-PSB7, BMERF-PSB16 and BMERF-PSB19) were found to be having plant growth promoting characteristics by producing Auxin.

Effects of feeding monensin on fatty acid profile of holstein dairy cows

This study was conducted to investigate the efficacy of monensin on milk fatty acid profile in Holstein dairy cows. For this study 12 cows with initial weight 625 ± 48 kg were allocated to control group and monensin group, with 6 replication in each group using completely randomized design (CRD). The experiment was accomplished during 21 days including pre trial period (14d) and feedlot period (7d). Diet was given twice daily to each group. The conjugated linoleic acid content of diets with monensin was higher than other and there were significant differences (P < 0.05).

In Egypt, Resedaceae is represented by 14 species belonging to five genera, genus Ochradenus is among them represented by one species (O. baccatus Delile). The studied Ochradenus baccatus populations collected from Wadi Degla, Egypt revealed that O. baccatus is gynodioecious species, with female individuals that are constant in sex expression and males that exhibit great variation in functional gender. The field study revealed the presence of inconstant male of O. baccatus in different forms ranging from high fruit-producing to low or nonfruit producing forms with two intermediate forms. The pollen morphology of all the four forms was examined using LM and SEM.
