SIMULATION STUDY OF HIERARCHICAL BAYESIAN APPROACH FOR SMALL AREA ESTIMATION WITH MEASUREMENT ERROR
Get PDFIn small area estimation (SAE), the auxiliary variables used are commonly derived from registration data such as census and administrative data. It is assumed that the auxiliary variables are available for all areas. The limited availability of auxiliary variables can be an obstacle in SAE. The additional information from the survey can be alternative data, but it is assumed that the auxiliary variables will contain measurement errors. This study conducted a simulation of data that aims to handle when auxiliary variables are measured with errors. Two simulations were studied with some scenarios to the percentage area where the auxiliary variable is measured with error and scenarios to the generated auxiliary variables. Compare four methods: direct estimation, Fay-Herriot Empirical Best Linear Unbiased Prediction (EBLUP-FH), Ybarra-Lohr SAE with measurement error (SaeME), and Hierarchical Bayesian SaeME. The results show that, in both the simulation study, the Hierarchical Bayesian SaeME method gives a smaller the EMSE value than the other two methods when auxiliary information is measured with error

No full textCorrelation of Lipopolysaccharide Endotoxin Level in Cotton Dust with the Increase of TNFα Level and the Decline of Lung Function in Cotton Spinning Factory Workers
Get PDFLipopolysaccharide (LPS) endotoxin contained in cotton dust may cause airway inflammation and decline of lung function when inhaled, which eventually leads to respiratory symptoms. The objective of this research is to analyze the correlation of the exposure of LPS endotoxin in cotton dust with the increase of TNFα level and the decline of lung function after one day’s work. This study applies analytical observation method and prospective cohort approach. Main participants of this study were the workers of a cotton spinning factory located in Tulangan District, Sidoarjo Regency, East Java Province. Sixteen samples from cotton factory were taken as study group, and twenty three samples from village administrators were taken as control group. Data collection involves several techniques: spirometry, laboratory test, and interview. Results showed that concentration of personal dust has a significant relationship with the decline of FVC, %FVC, FEV1, and %FEV1, with Pearson correlation test showing p<0.05. LPS endotoxin in personal dust samples has a significant relationship with the increase of blood serum TNFα and the decline of FEV1 and %FEV1, with Pearson correlation test showing p>0.05. The research concludes that the level of LPS endotoxin was strongly related to the increase of blood serum TNFα and the decline of lung function. Development of more effective preventive measures such as stronger enforcement of worker’s health maintenance regulations and use of personal protective equipment is needed to ensure the best protection of cotton workers’ health

Get PDFAbstrak
Pada masa pandemi ini aktivitas sedentari meningkat sangat pesat, peningkatan tersebut dikarenakan adanya pandemi dari virus Covid-19 yang mengharuskan masyarakat melakukan berbagai aktivitas dari rumah. Hal tersebut juga dirasakan oleh SMA Negeri 3 Lumajang, dimana terdapat peningkatan aktivitas sedentari karena waktu yang dihabiskan lebih banyak dipergunakan untuk bersekolah secara online dengan menggunakan media laptop, tablet, kemudian bermain handphone dan menonton televisi. Tujuan penelitian ini adalah untuk mengetahui ada atau tidaknya hubungan aktivitas peserta didik terhadap minat mereka dalam mengikuti kegiatan belajar mengajar pada mata pelajaran PJOK selama masa pandemi Covid-19 pada siswa SMA Negeri 3 Lumajang. Dengan menggunakan Rumus Slovin, didapatkan sampel penelitian sebanyak 16% atau 172 peserta didik dari seluruh populasi yang berjumlah 1.050 peserta didik di SMA Negeri 3 Lumajang. Kemudian menggunakan Quota Sampling untuk menentukan jumlah sampel dari masing masing angkatan. Instrumen untuk mengukur aktivitas sedentari menggunakan ASAQ (Adolescent Sedentary Activity Questionnaire) kemudian untuk mengukur minat siswa penulis menggunakan angket minat yang diadopsi dari artikel milik Retno Anjarsari mahasiswa Fakultas Ilmu Olahraga UNESA angkatan 2017, yang telah teruji validitasnya dengan nilai alpha 0,877 > 0,6. Analisis penelitian menggunakan korelasi gamma, dengan hasil perhitungan signifikansi dari kelas X, XI,dan XII > 0,05. Untuk koefisien hubungan Gamma kelas X sebesar 0,192, kelas XI dengan hasil -0,208, kemudian pada kelas XII dengan hasil -1,00. Dapat disimpulkan bahwa dari hasil penelitian yaitu tidak ada keterkaitan yang signifikan antara aktivitas sedentari dengan minat peserta didik pada pembelajaran PJOK di SMA Negeri 3 Lumajang.

Abstract
During this pandemic, sedentary activities increased very rapidly, this increase was due to the COVID-19 pandemic, which required people to carry out various activities from home. This is also felt by SMA Negeri 3 Lumajang, where there is an increase in sedentary activity because more time is spent going to school online using laptops, tablets, then playing cellphones and watching television. The purpose of this study was to find out whether or not there was a relationship between student activity and their interest in participating in teaching and learning activities in the PJOK subject during the Covid-19 pandemic in Lumajang 3 Public High School students. By using the Slovin Formula, a sample of 16% of the total population of students at SMA Negeri 3 Lumajang was obtained. Then use Quota Sampling to determine the number of samples from each batch. The instrument for measuring sedentary activity uses the ASAQ (Adolescent Sedentary Activity Questionnaire) and then to measure student interest the author uses an interest questionnaire adopted from an article belonging to Retno Anjarsari, a 2017 UNESA Faculty of Sports Science student, whose validity has been tested with an alpha value of 0.877 > 0.6. The research analysis uses gamma correlation, with the results of calculating the significance of class X, XI, and XII > 0.05. For the Gamma correlation coefficient for class X of 0.192, for class XI with a result of -0.208, then for class XII with a result of -1.00. It can be concluded that from the research results, there is no significant relationship between sedentary activities and students' interests in PJOK learning at SMA Negeri 3 Lumajang.

Prevalensi dan Faktor Risiko Tuli Akibat Bising pada Operator Mesin Kapal Feri
Get PDFKebisingan ruang mesin dapat menyebabkan gangguan pendengaran. Tujuan penelitian ini adalah menganalisis prevalensi tuli akibat bising Noise Induced Hearing Loss (NIHL) dan faktor yang memengaruhi pada operator mesin kapal feri penyeberangan Ketapang-Gilimanuk. Penelitian observasional dengan pendekatan cross sectional ini menggunakan metode pengumpulan data dengan wawancara, pengukuran intensitas kebisingan ruang mesin dan pemeriksaan audiometri terhadap operator. Besar sampel adalah 66 operator dari 36 kapal feri yang memenuhi kriteria inklusi dipilih secara acak. Hasil studi menunjukkan 36% kapal memiliki intensitas kebisingan ² 85 dBA dan 64% > 85 dBA. Pemeriksaan audiometri dengan nada murni pada 66 operator didapatkan 34,85% responden mengalami NIHL. Hasil analisis regresi logistik menunjukkan faktor dominan yang memengaruhi NIHL adalah usia dan lama paparan (p 85 dBA. The audiometric examination with pure tone result of the 66 operators showed that 34.85% of respondent had NIHL. The age and length of exposure affected NIHL incidence (p 0.05) together with age and lenght of exposure. It is important to reduce exposure time of noisy operations on workers, automation of activities and increase the distance between workers and noisy equipment to minimise the noise exposure
