Abstract

This study aims to determine the effect of liquid organic fertilizer application of banana fruit peel and get the best dose for the growth of areca seedlings. This research was conducted at experiment station of agriculture faculty of University of Riau from July to November 2017. This research was conducted in the form of experiment using completely non-factorial randomized designconsisting of 5 levels and 4 replications. The liquid organic fertilizer of banana fruit peel consists of 0, 250, 500, 750, 1000 ml.10 kg-1 medium. Data have been statistically analyzed and examined further with using the duncan's new multiple range test (DNMRT) at 5% level. The results showed that increased dosage of liquid organic fertilizer banana fruit peel increased the accretion height of seedlings, dry weight and shoot root ratio, but no increase the leaf number accretion, stem circumference and widest leaf area.The dosage of liquid organic fertilizer of banana fruit peel of 750 ml.10 kg-1 medium gives the increase of accretion height seedlings, dry weight and the highest shoot root ratio in 6 month old areca seedlings.Keyword : Seedlings, liquid organic fertilizer of banana fruit peel, growth

Abstract

Lack of organizational commitment often occurs among students who are administrators of the organization; they are still less able to set rules for themselves. These abilities are related to how one judges and interpret each action or commonly referred to as spiritual intelligence. This study aims to examine the relationship between spiritual intelligence and organizational commitment. The population in this study amounted to 919 people, with a sample of 92 administrators of UKK and UKM in the 2017/2018 period at UIN Antasari Banjarmasin. The sampling technique in this study uses probability sampling with a type of sample random sampling. The instrument of data collection uses the scale of organizational commitment and spiritual intelligence of the Likert model and analysis using Product Moment correlation with the help of SPSS 21.0. Based on the calculation results show that the level of organizational commitment and spiritual intelligence of students is classified as moderate. The results of the correlation test indicate a significant positive relationship between the two variables (p = 0.002, p <0.05). The higher the spiritual intelligence, the higher the student's organizational commitment and vice versa, the lower the spiritual intelligence, the lower the student's organizational commitment.

Abstract

Antidiabetic activity of Cocor Bebek leaves (Kalanchoe pinnata Lam.Pers.) ethanolic extract from Bogor city, Kabupaten Bogor and south of Tangerang city has been studied. The study was conducted in vitro using glucosidase inhibitor method. The results of the study showed that IC50 of the extract from Bogor city, Kabupaten Bogor, and Tangerang Selatan city is 40.94 ppm, 33.58 ppm and 16.12 ppm respectively. Meanwhile, IC50 of quersetin which has antidiabetic activity is 10.22 ppm. The results showed that Cocor Bebek leaves (Kalanchoe pinnata Lam.Pers.) ethanolic extract had antidiabetic activity with IC50 less than 100 ppm. However, the activity is lesser than quercetin.Keywords:Kalanchoe pinnata Lam.Pers, antidiabetic activity, glucosidase inhibitor

Abstract

This study aims to determine students' understanding of career selection after obtaining information services including career selection on sub-variables of motivation, knowledge, personality, abilities. One of the uses of the results of this study is as information for students, lecturers, teachers, students, and readers on how students' understanding of career selection in MAN 2 Batusangkar. The research method used in this study is the method of "Field Research" (field research) that is descriptive quantitative. The population in this study were students of class XII MAN 2 Batusangkar, totaling 256 people. The sample in this study were all students of class XII IS 1, amounting to 31 people in MAN 2 Batusangkar. The results showed that the understanding of students of class XII MAN 2 Batusangkar about career selection most students understood that the career would be continued at the College or Occupation and there were still a few who understood enough about the motivational factors that were lacking from individuals to choose the career they would choose for the future

Abstract

In this study, electrochemical detection of acrylamide using hemoglobin (Hb)-modified core–shell Fe3O4@Au nanostructures was conducted. Fe3O4 nanoparticles (~4.9 nm) and core–shell Fe3O4@Au (5.0–6.4 nm) nanostructures were successfully synthesized by the thermal decomposition method. Electrochemical investigation revealed that the optimum amount of Hb of 2 mg/mL could be immobilized in 0.1 M acetate buffer solution (pH = 6). Moreover, the detection of acrylamide using Fe3O4@Au/Hb was evaluated by the cyclic voltammetry technique. A linear calibration curve (R2 = 0.98) in the concentration range of 0.1 to 1.0 µM could be achieved with an estimated limit of detection, limit of quantification, and sensitivity of 0.136 µM, 0.453 µM, and 0.4411 µA/µM, respectively. Furthermore, the developed biosensor exhibited high selectivity in the presence of ascorbic acid, melamine, and caffeine. The developed biosensor was applied to the detection of acrylamide in coffee samples and validated using the standard high-performance liquid chromatography (HPLC) method. The concentration of acrylamide in coffee samples was determined to be 37.450 and 35.377 ppm using electrochemical measurement and HPLC, respectively.
