PENGARUH KOMITMEN ORGANISASI DAN KEPUASAN KERJA TERHADAP KETIDAKHADIRAN (ABSENTEEISM) PADA KARYAWAN PT. GIKOKO KOGYO INDONESIA

ABSTRACT JAPAR SIDIK DICKY ARIZONA. Influence Of Organizational Commitment And Job Satisfaction Of Employees In The Absenteeism Of PT. Gikoko Kogyo Indonesia. Script Paper, Jakarta : Office Administration Concentration of Education, Economics Education Studies Program, Departement of Economics and Administration, Faculty of Economics, State University Of Jakarta 2012. This study aims to determine the influence of organizational commitment and job satisfaction to absenteeism on employees. This research was conducted over four months from March to June 2012. The research method used is survey method through correlation approach. The study population is an employees of PT. Gikoko Kogyo Indonesia. Achievable population is an employee at departement of production. Sampling technique is a simple random sampling with a sample size of 55 employees. The instrument used to obtain data on the X1 variable (Organizational Commitment) was measured using a likert scale, then a X2 variable (Job Satisfaction) was measured using a likert scale. For the Y Variable (Absenteeism) obtained from the documentation of PT. Gikoko Kogyo Indonesia. Technique of data analysis began by looking for a multiple regression equation and obtained the regression equation Y = 12,437-0,066X1-0,064X2; whereas the normality test requirements analysis by using SPSS 17,0 Sig. values obtained absenteeism of normality of 0,081; organizational commitment of normality of 0,200 and job satisfaction of normality of 0,200 for the Sig. > 0,05 means that the sample came from normality populations. A linierity test by using SPSS 17.0 obtained the values of significant test for absenteeism to organizational is 0,082 and the values of significant test for absenteeism to job satisfaction is 0,328 and 0,05 which means the normal regression model is linier. Partial correlation coeficient value of organizational commitment in the absenteeism of -0,405 and job satisfaction in the absenteeism of -0,488 means both the independent variable on the deendent variable is beeing. Then obtained by simultaneous correlation coefficient 0,762, which means the correlation is strong. Autocorrelation test is obtained at 1,645, which means the value is free from problems of autocorrelation. Multicollinearity tolerance test values obtained for 0,594 and the VIF values of 1,685 and this suggests the model is not the case multicollinearity. Heteroscedasticity test is obtained through a test of orgnizational commitment by Glejser test to 0,102 and job satisfaction to 0,091 so there are no heteroscedasticity. F test obtained through SPSS 17.0 for 36,102 > 3,17 F table with a significance 0,000 < 0,05 and inferred organizational commitment and job satisfaction simultaneously affect absenteeism. Significance test with the organizational commitment to absenteeism with tcount -3,197 and ttable -1,667 for significance 0,002 and job satisfaction to absenteeism with tcount -4,027 and ttable 1,667 for significance 0,000. Because –tcount < -ttable, the researchers conclude there is a negative influence between Organizational commitment to the absenteeism thus there is a negative influence between job satisfaction to the absenteeism. Coeficience of determination test is 0,581 or 58,1%. From the Determination test, the researchers defined that absenteeism are determined by the organizational commitment and job satisfaction yield of 58,1%. Then it can be concluded there are a negetive and significant influence between organizational commitment and job satisfaction on the absenteeism of the employee

Imaging profile of the ear in hearing loss patients in Hospital Universiti Sains Malaysia

Introduction: Hearing impairment is a major disability. The otologic assessments together with high-resolution CT images were able to obtain precise diagnostic profile of ear malformations. These details are essential for further management of patients. Objective: This study was conducted to investigate the detailed anatomical profile of the ears in hearing loss patient in Hospital Universiti Sains Malaysia by highresolution CT scan of the temporal bone. Methodology: This was a cross-sectional study of high resolution CT scans of temporal bone from 1st January 2008 to 31st May 2014 in HUSM. The study sample consisted of all patients with hearing loss who had undergone HRCT in HUSM and fulfilled the study criteria. Results: In this study, which consisted of 55 patients, 40% of patients showed some form of abnormality on the HRCT temporal bone with 36.4% with outer ear abnormality, 9.0% had middle ear abnormality, 40.1% noted to have inner ear abnormality and 13.6% with multiple areas of abnormality. In term of laterality, 54.5% were observed to have bilateral diseases, 27.3% on right ear and the remaining 18.2% had it on the left ear. The mean vestibular aqueduct diameter was 0.08 ± 0.09 cm (R) and 0.06 ± 0.04 cm (L), lateral semicircular canal diameter 0.10 ± 0.03 cm (R) and 0.10 ± 0.02 cm (L), vestibule diameter 0.30 ± 0.06 cm (R) and 0.31 ± 0.05 cm (L), bone width between the lateral vestibular wall and the inner wall of the lateral semicircular canal diameter 0.35 ± 0.07 cm (R) and (L) and internal acoustic meatus diameter 0.40 ± 0.08 cm (R) and 0.41 ± 0.08 cm (L). Patients with external ear abnormality were observed to have normal to severe hearing loss, patients with middle ear abnormality had mild to severe hearing loss and patients with inner ear abnormality had normal to profound hearing loss. The most common inner ear abnormalities in this study were enlarged vestibular aqueduct and cochlear ossifications. Conclusion: This study showed that HRCT temporal bone could detect ear abnormality up to 40% of patients with hearing loss and most common abnormality would be enlarged vestibular aqueduct and cochlear ossification. The severity of hearing loss was higher in patients with inner ear abnormality

Changes in macroalgae species composition, assemblage and coverage at an inter-tidal rocky shore.

Samplings of macroalgae were undertaken at an inter-tidal rocky shore of Kuala Similajau (Lat. 3°22′ 13.9′N, Long. 113°17′ 39.1″E), Bintulu, Sarawak during two peaks of wet period; Feb.-Mar. (monthly total rainfall of 514.0 mm, 481.6 mm; average temperature 25.7℃, 26.2℃) and Jul.-Aug.(monthly total rainfall 585.8 mm, 566.2 mm; average temperature 26.3℃, 27.0℃) 2008. This study investigates the changes in macroalgae species composition, assemblage and coverage covering the two peaks of wet period. A total of 23 taxa comprising 7 green, 5 brown and 11 red algae were recorded covering the two peaks of wet period, with red algae being the most diverse division. Comparatively a lower number of macroalgae species occurred during Feb.-Mar. (12 species) compared to the period of Jul.-Aug. (20 species). Several species such as Ulva clathrata (Roth) Greville, Valonia aegagropila C. Agardh and Lobophora variegata (Lamouroux) Womersley ex Oliveira, were absent during the Feb.-Mar. Common species Anadyomene plicata C. Agardh, Sargassum sp., Acanthophora spicifera (Vahl) Borgesen, Amphiroa fragilissima (Linnaeus) Lamouroux, Gelidiella acerosa(Forsskal) Feldmann & Hamel, Gracilaria salicornia(C. Agardh) Dawson, Hydropuntia edulis (S. G. Gmelin) P. C. Silva, Laurencia papillosa (C. Agardh) Greville and Laurencia sp. were present in both periods. Acetabularia major C. Agardh, Cladophora prolifera (Roth) Kutzing, Ulva intestinalis (Linnaeus) Nees, Padina minor Yamada, Ceramium sp. and Pterocladia sp. were only present in the Jul.-Aug. In terms of mean coverage, there is no distinct trend in domination with respect to a particular species between the two peaks of wet period. However, based on the number of mean coverage contributed by the species, categorically this can be represented as Division Rhodophyta>Division Chlorophyta>Division Phaeophyta

Review: Tea Tree (Melaleuca Alternifolia) As A New Material For Biocomposites

Melaleuca alternifolia or commonly known as tea tree is a tall shrub or small tree in the plant genus Melaleuca. It is popular for its oil, which is tea tree oil where it has been employed largely in various industries of its antimicrobial properties. Research works are still ongoing mainly focusing on the tea tree oil properties, ultimately almost none of them investigating on the residue which is the leaves. Environmental issues become the world major concern, which create awareness among industrial player to turn back to natural fibre in producing products. In recent time, productions of composites from agro waste have received considerable attention. This paper aims to rationalize the potential of tea tree (Melaleuca alternifolia) leaves as a new source of natural fibres or material in order to become the potential filler or reinforcer in the development of a new biocomposite
