This experiment was carried out to examine the effect of a silicate fertilizer on the growth and development of potted plants. Cutting of Kalanchoe blossfeldiana 'Kaluna' and 'Taos', and Dianthus caryophyllus L. 'Kazan' and 'Tula' were grown in 50 and 128-cell plug trays, respectively. Rooted cuttings transplanted to the mixture of a commercial medium and perlite (5:1, v/v) supplemented with a silicate fertilizer at 0, 40, 80, 120 or $160g{\cdot}L^{-1}$ medium was evaluated. A silicate fertilizer supplementation at $40g{\cdot}L^{-1}$ medium resulted in the greatest plant height, leaf thickness, and root fresh and dry weights in both kalanchoe and carnation. However, plant height was suppressed in the treatment of a silicate fertilizer supplementation at higher concentrations in both kalanchoe and carnation. According to the scanning electron microscope images of transversal sections of tissues of roots and leaves in kalanchoe and carnation, the treatment of a silicate fertilizer supplementation at $40g{\cdot}L^{-1}$ medium resulted in plants with more compact tissue than the control.

Acetobacter xylinum KJ1 efficiently producing bacterial cellulose(BC) In shaking culture was isolated from a rotten grape. The strain was used to investigate optimum operating conditions for increasing BC production and factorial design model was employed for the optimization. The results of experiments were statistically analyzed by SAS program. Reciprocal effects of each factors(carbon source concentration, shaking speeds(rpm), oxygen pressure, and CSL concentration) and culture condition of BC production were examined by getting regression equation of the dependent variable. Comparisons between experimental results and predicted results about BC concentration were done in total 24 experiments by combination of each factors using SAS program, and the correlation coefficients of BC concentration and BC yield were 0.91 and 0.81, respectively. The agitated cultures were peformed in various operation conditions of factors which affected considerably to BC production in jar fermentor. The results showed that BC concentration was 11.67 g/L in 80 hours cultivation under the condition of carbon source concentration : shaking speeds(rpm) : oxygen pressure : CSL concentration : 4% : 460 rpm : 0.28 : 6%. On the other hand BC yield was 0.42 g/g in 80 hours cultivation under the condition of carbon source concentration : shaking speeds(rpm) : oxygen pressure : CSL concentration : 4% : 564 rpm : 0.21 : 2%. The BC production could be enhanced up to more than 2.4 times by factorial design. The result of a verifying experiment under the optimal conditions determined by the factorial design to the BC production showed that the model was appropriate by obtaining BC concentration of 11.47 g/L in the optimum condition.

The aim of this study was to investigate the effect of gamma irradiation on the pretreatment of wood chips with NaOH solution. The degree of saccharification was quantified by measuring reducing sugar and glucose concentrations after enzymatic hydrolysis. After pretreatment with 10 g/L NaOH, the wood chips were irradiated at the doses of 0, 50, 100, and 200 kGy, respectively. Among the irradiated samples, wood chips irradiated at the dose of 200 kGy had the highest reducing sugar concentration of 12.2 g/L. Also, to define the effect of irradiation before pretreatment, the wood chips were first gamma-irradiated and then pretreated with NaOH. When the NaOH treatment was conducted after irradiation at 200 kGy, the reducing sugar content was further increased to 13.4 g/L and glucose content of the wood chip was as high as 7.9 g/L. These results suggest that gamma irradiation may be the promising method for pretreatment of cellulose biomass.

This study aims to test the influence of employee competency and career management on career commitment in Indonesia. The study uses the cross-sectional data of regional government employees collected from February to April 2020. Regression and structural equation modeling are employed. The results base on the effect of employee competency and career management on career commitment in Indonesia are in line with the existing theory (i.e., Bandura's Career Theory). Employee competency has a significant positive influence on career management and career commitment, which shows that regional government employees with high competency generate effective career management, and in turn career commitment increased. Regional governments with their career management program should formulate human resources management practice policy (e.g., career support, training, career development program, and orientation programs) in order to increase their competency. The positive effect of employee competency on career management is because of the effective training and career development program. The positive influence of career management on career commitment is due to the regional government providing an attractive career program, thus, employees' career commitment improved. The positive influence of employee competency on career commitment via career management is implemented by regional government support to improve the career management program.
