The study was a descriptive research is descriptive quantitative instruments backed by descriptive statistics. Primary data was explored by a questionnaire and tabulation using the Likert scale from 1 for very poor performance to score 5 for best performance. Secondary data was collected from the literature relevant to the purpose of research. Analytical instruments including the relative frequency, cumulative frequency, aritmethic mean and standard deviation. All instruments are supported by means of SPSS in analyzing the menu Analyze Descriptive Tabulation of Frequency and summary Reports in the column. The analysis showed that the performance of lecturers in four competencies include pedagogic competence, professional, personal and social development can be said to be good overall. Nevertheless, based on student perceptions of discipline and compliance issues as well as control of media and instructional technology professors also need to be improved, especially in the use of existing facilities.

Abstract

This study aimed to assess the effectiveness in dealing with betel leaf extract catfish infected with Aeromonas hydrophila. This study used an experimental method to completely randomized design (CRD) with 4 treatments and 4 replications. Treatment consists of feed pellets P1 = + 0.2 g of betel leaf extract / 100 g feed; P2: feed pellets + 0.4 g of betel leaf extract / 100 g feed, P3: feed pellets + 0.6 g of betel leaf extract / 100 g of feed, and P4: feed pellets without betel leaf extract (control). Catfish used a length of 7.8 to 11.3 cm with an average weight of 7.43 g. Feed containing betel leaf extract made after the onset of symptoms of fish to bacteria A. hydrophila, namely on day 3 to day 18 (for 15 days). Parameters be measured were survival rate, clinical symptoms (external) fish, and the process of recovery (recovery) of catfish after bacterial infection A. hydrophila, as well as water quality parameters, including temperature, pH, and dissolved oxygen. Analysis of data using Analysis of Variance (ANOVA) and Duncan's test further with Multiple Range Test (DMRT) at 5% level test. The results showed that the betel leaf extract effective in preventing bacterial infection catfish A. hydrophila. Treatment of betel leaf extract may improve survival catfish reaches 66.67 to 86.11% compared to 30.55% for controls. P1 treatment is the most effective treatment for treating bacterial infections catfish A. hydrophila. Keywords: effectiveness, betel leaf extract, catfish, infection, Aeromonas

Abstract

In the present study has addressed the application of noise canceling FxAFA using dynamic step size algorithm, and we got the result that the noise reduction of FxAFA dynamic step size algorithms better then FxAFA algorithm. But when Compared with the noise reduction to FxLMS algorithms, FxLMS still better than the FxAFA dynamic step size algorithm. Based on the data from the computer simulation results of noise reduction FxLMS = 27.6793 dB, FxAFA dynamic step size and FxAFA db = 26.0329 = 23.6059 dB. Keywords: FxAFA, FxAFA dynamic adaptation measures, noise removal
