Hubungan antara Persepsi terhadap Kebisingan dengan Stres Karyawan

Penelitian ini bertujuan untuk mengetahui hubungan antara persepsi terhadap kebisingan dengan stres karyawan PT. PLN (Persero) PLTU Sektor Asam Asam. Subjek penelitian ini adalah karyawan / pekerja lapangan bagian operator mesin pada PT. PLN (Persero) PLTU Sektor Asam Asam, dengan kriteria karyawan / pekerja yang berjenis kelamin pria. Jumlah subjek penelitian sebanyak 40 orang. Subjek dipilih dengan menggunakan teknik purposive random sampling. Subjek penelitian berusia 20 tahun sampai dengan 50 tahun. Tingkat pendidikan subjek penelitian adalah STM Mesin berjumlah 14 orang, STM Listrik berjumlah 9 orang, D1 Mesin berjumlah 3 orang, D1 Listrik berjumlah 8 orang, D3 Mesin berjumlah 4 orang dan S1 Tehnik Mesin berjumlah 2 orang. Instrumen yang digunakan dalam pengumpulan data adalah Kuesioner untuk mengukur Persepsi Terhadap Kebisingan dan Skala untuk mengukur Stres. Sebelum digunakan instrumen-instrumen ini diujicoba terlebih dahulu. Hasil penelitian menunjukkan bahwa koefisien korelasi Persepsi Terhadap Kebisingan dengan Stres adalah ( r = 0,482 dengan p = 0,003 (p < 0,01) ). Hal ini menunjukkan bahwa ada hubungan positif antara persepsi terhadap kebisingan dengan stres karyawan PT. PLN (Persero) PLTU Sektor Asam Asam diterima. Jadi, semakin tinggi persepsi terhadap kebisingan, maka semakin tinggi pula tingkat stres, dan semakin rendah tingkat persepsi terhadap kebisingan, maka semakin rendah pula tingkat stres. Kata kunci : Persepsi terhadap kebisingan, stress This study aims to determine the relationship between perceptions of noise with the stress of employees PT. PLN (Persero) PLTU Sektor Asam Asam. The subject of this study were employees / workers in the field of machine operators PT. PLN (Persero) PLTU Sektor Asam Asam, the criteria of employees / workers who are male. The number of subjects is 40 people. Subjects were selected using purposive random sampling technique. Subjects aged 20 years to 50 years. The subjects education level is STM Machine totaled 14 people, STM Electrical totaled 9 people, D1 Machine totaled 3 people, D1 Electrical totaled 8 people, D3 Machine totaled 4 people and S1 Techniques Machine totaled 2 people. Instruments used in data collection are questionnaires to measure Perception of noise and Scale to measure stress. Prior to use these instruments are tested first. The results showed that the correlation coefficient Perceptions of noise with the Stress is ( r = 0.482 with p = 0.003 (p <0.01) ). This suggests that there is a positive relationship between perceptions of noise with the stress of employees PT. PLN (Persero) PLTU Sektor Asam Asam be accepted. Thus, the higher the perception of noise, the higher the stress level, and the lower the perceived level of noise, then the lower the stress level

Zero-point vacancies in quantum solids

A Jastrow wave function (JWF) and a shadow wave function (SWF) describe a quantum solid with Bose--Einstein condensate; i.e. a supersolid. It is known that both JWF and SWF describe a quantum solid with also a finite equilibrium concentration of vacancies x_v. We outline a route for estimating x_v by exploiting the existing formal equivalence between the absolute square of the ground state wave function and the Boltzmann weight of a classical solid. We compute x_v for the quantum solids described by JWF and SWF employing very accurate numerical techniques. For JWF we find a very small value for the zero point vacancy concentration, x_v=(1.4\pm0.1) x 10^-6. For SWF, which presently gives the best variational description of solid 4He, we find the significantly larger value x_v=(1.4\pm0.1) x 10^-3 at a density close to melting. We also study two and three vacancies. We find that there is a strong short range attraction but the vacancies do not form a bound state.Comment: 19 pages, submitted to J. Low Temp. Phy

Swedish immersion in the early years in Finland

Immersion education in Finland is a one-way (monolingual) early total Swedish programme for Finnish-speaking students. This immersion provision is offered at kindergarten level (ages 3–5), at preschool (age 6) and at primary levels (grades 1–9). Here, a brief synthesis of Finnish research studies on the early years in Swedish immersion is first provided, reviewing results from a number of quantitative and qualitative research studies. In order to present a comprehensive view of the Finnish context, both the kindergarten and preschool environments are analysed as contexts for early second-language learning and teaching. The second part of this article presents results from a recent Finnish study of immersion in kindergarten, where analyses of dialogue sequences make it possible to examine in depth how immersion children in Finland learn their new language in everyday situations within immersion settings. Examples illustrate the importance of the educator's explicit verbalisations of every joint activity and shared context. When the educator continuously puts into words the actions jointly focused upon by child and adult, she provides meaningful L2 input and, at the same time, promotes children's understanding of daily activities. The excerpts also show developments in children's emerging L2 utterances, from recycled Swedish language items to spontaneous L2 use
