The purpose of this study was to determine the relationship between students’ personality and environment with their Indonesian Language ability. This research was conducted in South Tangerang City involving 392 2nd grade students. This research method used correlational method with quantitative approach by using descriptive statistics. Data was collected using an assessment scale instrument and analyzed by using correlation technique (regression). The results of this study showed that: (1) There was a positive relationship between personality and students’ Indonesian Language ability with a significant level of α = 0.05, obtained tcal 8.77 ˃ ttable 1.97. (2) There wasa positive relationship between the environment and the students’ Indonesian Language ability with a significant level of α = 0.05, which obtained 9.03 ˃ t table 1.97. (3) There was a positive relationship between personality and environment with the students’ Indonesian Language ability; with a significant level of α = 0.05, obtained tcal 7.92 ˃ t table 1.97. The Implications of the study identified that Indonesian Language ability of the students can be influenced by their personality and environment.

AbstractInsect-pollinated plants are essential for honey bees to feed their brood. In agricultural landscapes, honey bees and other pollinators are often exposed to pesticides used for cultivation. In order to gain more insight into the fluctuation of pesticide loads, 102 daily pollen samples were collected between April and July 2018 in a fruit-growing area in Southern Germany. Samples were analyzed with respect to more than 260 pesticides using a multi-residue pesticide analysis method. Almost 90% of the analyzed pollen samples featured between one and thirteen different pesticides. In total, 29 pesticides were detected at maximum concentrations of up to 4500 ng/g pollen. Maximum residual concentrations of most pesticides were observed during April and the first half of May, as well as during the second half of June. In most cases, serial data of pesticide residuals were detected for approximately 10 subsequent days with two or three maximum values, which were several folds higher than concentrations on the days before and thereafter. The pollen hazard quotient (PHQ) was calculated to estimate the risk of the detected pesticides to honey bees and wild pollinators.

A new transceiving protocol is designed for an FSO communication system, and it’s discussed from the transmitting protocol and the receiving protocol. Different from wired communication, a FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere, and the protocol is optimized for terrestrial FSO links. Due to the complex composition and activity of the atmosphere, this signal channel brings in great influence on the transmitting laser in it. The function of the receiving protocol includes filtering and synchronizing the input serial data stream, paralleling the serial data stream, decoding the input data, error checking, and exception handling and interfacing the outer receiver with a parallel port. The transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. We also test the hardware platform and communication protocol and give the waveform. The experiment and Simulation prove that the protocol presented can work well at a certain bit rate scale.

AbstractUse of inter-pupillary distance (IPD) for objective evaluation of ocular hypertelorism and hypotelorism is recommended to corroborate diagnosis of syndromic conditions. In view of complete absence of serial data on growth of IPD, this study aims to unfold auxological dynamics of IPD in Down syndrome (DS) children of Indian origin. Inner canthal distance (ICD) and outer canthal distance (OCD) were measured on a total of 1,125 (male: 752, female: 373) DS children, aged 0 to 3 months to 10 years at 6 monthly age intervals using a “Digimatic Sliding Caliper” in the Growth Laboratory/Growth Clinic of the Institute. Using Feingold and Bossert (1974) formula, IPD at each age was calculated from ICD and OCD measured among male and female DS children. IPD, like OCD and ICD increased un-interruptedly among DS children. IPD grew rapidly up to 5 years thereafter, its rapidity became slower. Boys in general, possessed larger IPD than girls, however, gender differences became statistically significant up to first 4 years of life. Our study children possessed significantly smaller IPD as compared with their normal Indian counterparts. None of our DS children depicted ocular hypertelorism while hypotelorism, was noticed amongst 4.9% male and 16.8% female DS patients. Comparison with normative IPD data failed to establish existence of ocular hypertelorism in DS children (<10 years) of north-western Indian origin. Use of age and gender-specific data presented for IPD of DS children may be made for comparative purpose to ascertain inter-population variability.

<p>The goal of the present paper is to analyze the effect of personnel's education and psychological competence on<br />quality of service. The mediation role of organizational competence in Ministry of the Interior is of<br />descriptive-correlational method. To do that, the standard questionnaire psychological competence by Spriters<br />(1995), personnel education and quality of service by Deher (2015) and organizational commitment by Alen and<br />Mier (1990) were used. The statistical population of the research includes all personnel of Ministry of the<br />Interior which are 1600 subjects. Based on Cochran's formula, 3100 subjects were selected randomly. In order to<br />analyze data the Pearson's correlation test and structural equation of data analysis were used by SPSS and AMOS<br />software. The findings of the research indicate that personnel's education has a positive effect on organizational<br />competence and quality of service (with Alpha level of 0.05). Moreover, the psychological competence is<br />positively affect the quality of service (with Alpha level of 0.05) and organizational commitment affect the<br />quality of service. Finally, it was revealed that the personnel training through organizational commitment affect<br />the quality of service. But, psychological competence does not affect the quality of service through<br />organizational commitment. Moreover, psychological competence does not affect the organizational commitment.<br />The significance levelof the model turned out to be more than the first type error (0.05). This shows that the<br />significant adaption of the estimated model with the present research model. Furthermore, the AGFI and GFI<br />indicators are more than the estimated value (0.9). These indicators show that the model has a capability in<br />estimating the ratio of each factor.</p>

This study aims to determine the relationship of service quality to the satisfaction of recipients of population administration services at the Population and Civil Registry Office of Tanah Datar District. Measurement of service quality dimensions using five dimensions of service quality consisting of dimensions of physical evidence (tangibles), reliability (reliability), responsiveness (responsiveness), assurance (assurance), empathy (empathy). This type of research is a quantitative study with a correlational method using SPSS version 22. The population of this study is the population receiving population administration services in Dukcapil Tanah Datar District, a population of 82,286 people with a sample of 100 people taken using the Slovin formula using accidental sampling techniques. The research data is primary data, the data collection technique in this study is to use a questionnaire prepared using a Likert scale whose scores are 1-5. To ensure that the instruments used in the study are validity and reliability tests. Data were analyzed by descriptive and inductive analysis using normality test, linearity test, hypothesis testing using multiple correlation test, person correlation test, and the coefficient of determination test with α = 0.05. The results of this study show that the five service quality variables have a positive and significant relationship to the satisfaction of recipients of population administration services, namely the dimensions of physical evidence (tangibles), reliability (reliability), responsiveness (responsiveness), assurance (assurance), and empathy (empathy). Keyword:  kualitas pelayanan, bukti fisik (tangibility), keandalan (reliability), daya tanggap (responsiveness), jaminan (assurance), empati (emphaty), dan kepuasan masyarakat penerima layanan.
