Abstract: Decreased work productivity can be caused by working stress. There are factors that can affect working stress, including working time and workload. A 24-hour airport operating system requires employees who are security check points at the airport to be firm in conducting inspections with different characters, behaviors, and cultures each day. The heavy hours and flight routes ranging from domestic to overseas every day and excessive workload or work demands can potentially lead to occupational stress. This study was aimed to obtain the relationship between workload and working time and working stress among security check point employees at PT Angkasa Pura I Sam Ratulangi International Airport Manado. The total population of this study was 68 employees. The Spearman corelation test showed that there was a significant relationship with a positive correlation of strong category between workload and working stress among the security check point employees (p=0.000; r=0.608). Moreover, there was a significant relationship between between working time and working stress (p=0.001; r=- 0.411). In conclusion, there was a significant positive relationship between work load and working stress and a significant negative relationship between working time and working stress among the employees on the security check point at PT Angkasa Pura I Sam Ratulangi International Airport Manado.Keywords: workload, working period, work stress.Abstrak: Produktivitas kerja yang menurun dapat disebabkan oleh stres kerja. Terdapat faktor– faktor yang dapat memengaruhi stres kerja antara lain meliputi masa kerja serta beban kerja. Sistem operasi bandar udara selama 24 jam, menuntut para pekerja security check point di bandar udara harus tegas dalam melakukan pemeriksaan dengan karakter, perilaku, serta budaya yang berbeda tiap harinya. Padatnya jam dan rute penerbangan mulai dari domestik sampai ke luar negeri setiap harinya serta beban kerja atau tuntutan kerja yang berlebihan dapat berpotensi mengakibatkan stres kerja. Penelitian ini bertujuan untuk mengetahui hubungan antara beban kerja dan masa kerja dengan stres kerja pada security check point di PT Angkasa Pura I Bandar Udara Internasional Sam Ratulangi Manado. Populasi penelitian ini yaitu seluruh pekerja yang berjumlah 68 orang. Hasil uji statistik Spearman mendapatkan hubungan bermakna dengan korelasi positif kategori kuat antara beban kerja dengan stres kerja (p=0,000; r=0,608). Selain itu terdapat hubungan berlawanan arah (negatif) antara masa kerja dengan stres kerja (p=0,001; r=-0,411). Simpulan penelitian ini ialah pada security check point di PT Angkasa Pura I Bandar Udara Internasional Sam Ratulangi Manado terdapat hubungan bermakna yang positif antara beban kerja dengan stres kerja serta terdapat hubungan bermakna yang negatif antara masa kerja dengan stres kerja.Kata kunci: beban kerja, masa kerja, stres kerja

Security Check

The paper deals with possibilities of optimizing the process of check-in and security check at airport terminals using simulation program. Proposed model is based on real parameters and simulated in the environment of the program Tecnomatix Plant Simulation. This program simulates the process of check-in and security check. Queuing theory will be used for simulation. Principally it means queuing customers, i.e. accumulation of requests, in front of a service centre. Limiting criteria for optimization include operating conditions of airport terminals, financial means connected with personnel resources, legal standards related to safety in air transport and level of service indicators. The aim of the paper is to create a model, which analyses the passenger flow processes at the airport terminal and could be used for evaluating potential changes of the check-in and security check system at airport terminals.

At the level of manifest categorical variables, a large number of coefficients and models for the examination of rater agreement has been proposed and used. The most popular of these is Cohen's κ. In this article, a new coefficient, κ s , is proposed as an alternative measure of rater agreement. Both κ and κ s allow researchers to determine whether agreement in groups of two or more raters is significantly beyond chance. Stouffer's z is used to test the null hypothesis that κ s = 0. The coefficient κ s allows one, in addition to evaluating rater agreement in a fashion parallel to κ, to (1) examine subsets of cells in agreement tables, (2) examine cells that indicate disagreement, (3) consider alternative chance models, (4) take covariates into account, and (5) compare independent samples. Results from a simulation study are reported, which suggest that (a) the four measures of rater agreement, Cohen's κ, Brennan and Prediger's κ n , raw agreement, and κ s are sensitive to the same data characteristics when evaluating rater agreement and (b) both the z-statistic for Cohen's κ and Stouffer's z for κ s are unimodally and symmetrically distributed, but slightly heavy-tailed. Examples use data from verbal processing and applicant selection.

Abstract. When principal component solutions are compared across two groups, a question arises whether the extracted components have the same interpretation in both populations. The problem can be approached by testing null hypotheses stating that the congruence coefficients between pairs of vectors of component loadings are equal to 1. Chan, Leung, Chan, Ho, and Yung (1999) proposed a bootstrap procedure for testing the hypothesis of perfect congruence between vectors of common factor loadings. We demonstrate that the procedure by Chan et al. is both theoretically and empirically inadequate for the application on principal components. We propose a modification of their procedure, which constructs the resampling space according to the characteristics of the principal component model. The results of a simulation study show satisfactory empirical properties of the modified procedure.

Information Matrix Test

In this manuscript, a new approach to the analysis of person fit is presented that is based on the information matrix test of White (1982) . This test can be interpreted as a test of trait stability during the measurement situation. The test follows approximately a χ2-distribution. In small samples, the approximation can be improved by a higher-order expansion. The performance of the test is explored in a simulation study. This simulation study suggests that the test adheres to the nominal Type-I error rate well, although it tends to be conservative in very short scales. The power of the test is compared to the power of four alternative tests of person fit. This comparison corroborates that the power of the information matrix test is similar to the power of the alternative tests. Advantages and areas of application of the information matrix test are discussed.
