Pengaruh Kualitas Pelayanan dan Kepuasan terhadap Loyalitas

The research aims to find out the impact of service quality and satisfaction on loyalty. Five dimensions of service quality i.e. issue program, academic reputation, physical aspect, career opportunity, contact personnel, responsiveness, and communication were analyzed. This research is descriptive – quantitative in nature. Data were obtained by using questionnaire which was distributed to the students of SMK Negeri 11, Jakarta. Using proportionate stratified random sampling technique, total sample of 87 respondents were obtained. Data were examined using both descriptive and statistical analysis. Results indicated physical aspect, responsiveness, and communication had the influence on the student satisfaction, meanwhile contact personnel, responsiveness, communication, and satisfaction had the effect on loyalty. Physical aspect had an indirect influence on student loyalty. It is suggested that the management pay more attention to program, academic reputation, career opportunity, and contact personnel. There is also a need for more research to answer which physical aspect is the most dominant

Kinetic simulation of the sheath dynamics in the intermediate radio-frequency regime

The dynamics of temporally modulated plasma boundary sheaths is studied in the intermediate radio frequency regime where the applied radio frequency and the ion plasma frequency are comparable. Two kinetic simulation codes are employed and their results are compared. The first code is a realization of the well-known scheme, Particle-In-Cell with Monte Carlo collisions (PIC/MCC) and simulates the entire discharge, a planar radio frequency capacitively coupled plasma (RF-CCP) with an additional heating source. The second code is based on the recently published scheme Ensemble-in-Spacetime (EST); it resolves only the sheath and requires the time resolved voltage across and the ion flux into the sheath as input. Ion inertia causes a temporal asymmetry (hysteresis) of the sheath charge-voltage relation; also other ion transit time effects are found. The two codes are in good agreement, both with respect to the spatial and temporal dynamics of the sheath and with respect to the ion energy distributions at the electrodes. It is concluded that the EST scheme may serve as an efficient post-processor for fluid or global simulations and for measurements: It can rapidly and accurately calculate ion distribution functions even when no genuine kinetic information is available

An integrative approach to predicting the functional effects of small indels in non-coding regions of the human genome

Background: Small insertions and deletions (indels) have a significant influence in human disease and, in terms of frequency, they are second only to single nucleotide variants as pathogenic mutations. As the majority of mutations associated with complex traits are located outside the exome, it is crucial to investigate the potential pathogenic impact of indels in non-coding regions of the human genome. Results: We present FATHMM-indel, an integrative approach to predict the functional effect, pathogenic or neutral, of indels in non-coding regions of the human genome. Our method exploits various genomic annotations in addition to sequence data. When validated on benchmark data, FATHMM-indel significantly outperforms CADD and GAVIN, state of the art models in assessing the pathogenic impact of non-coding variants. FATHMM-indel is available via a web server at indels.biocompute.org.uk. Conclusions: FATHMM-indel can accurately predict the functional impact and prioritise small indels throughout the whole non-coding genome
