Transportasi merupakan hal yang sangat dibutuhkan dalam menunjang pembangunan nasional. Belum baiknya sistem transportasi massal di Indonesia, membuat masyarakat lebih memilih menggunakan kendaraan pribadi, seperti sepeda motor yang praktis dan ekonomis untuk digunakan. Namun, dalam menggunakan sepeda motor, aspek ergonomi dan kenyamanan bagi pengendara perlu untuk diperhatikan. Desain dan ukuran tempat duduk sepeda motor yang tidak sesuai dengan antropometri duduk statis pengendara dapat menimbulkan kelelahan pada pengendara dan mengakibatkan terjadinya kecelakaan. Tujuan dari penelitian ini adalah untuk mengetahui risiko ergonomi dari ketidaksesuaian antara desain dan ukuran tempat duduk sepeda motor dengan antropometri duduk statis. Untuk menganalisis risiko ergonomi, dilakukan penelitian dengan desain deskriptif analitik pada mahasiswa di sekitar lingkungan kampus Fakultas Kesehatan Masyarakat Universitas Indonesia pada bulan Oktober sampai dengan Desember 2009. Jumlah sampel sebanyak 100 orang responden, dibagi menjadi 50 orang laki-laki dan 50 orang perempuan. Sampel responden dipilih dengan metode cluster random sampling, sedangkan tipe sepeda motor dipilih berdasarkan yang paling banyak digunakan dengan metode simple stratified random sampling. Hasil penelitian menunjukkan bahwa terdapat ketidaksesuaian antara ukuran tempat duduk sepeda motor dengan antropometri duduk statis pada mahasiswa. Adanya ketidaksesuaian tersebut dapat mengakibatkan risiko ergonomi pada pengendara dan terjadinya kecelakaan lalu lintas.  Ergonomic Risks of Incompatibility of Design and Size of Motorcycle Seat againts Anthropometry among College StudentsTransportation is something needed most to support national development. Bad mass transportation system in Indonesia, makes people prefer to use private vehicles, such as motorcycle which is practical and economical to use. However, riders need to consider ergonomic and comfortability aspects in using motorcycle. The design and size of motorcycle seat in compatible with the rider’s static seat anthropometry may cause fatigue among riders and lead to accidents. The study aimed to find out ergonomic risks of incompatibility between the design and size of the motorcycle seat with static sitting anthropometry. To analyze the ergonomic risks, this study was conducted using analitical descriptive design among college students at Public Health Faculty Universitas Indonesia on October to December 2009. The total sample was 100 respondents, divided into 50 men and 50 women. The sample of respondents was selected using random cluster sampling method, meanwhile the type of motorcycle was selected based on the most widely used with simple stratified random sampling method. The results showed any incompatibility between the size of motorcycle seat with static sitting anthropometry among collage students. Such incompatibility may cause ergonomic risks among rider and lead to traffic accidents.

Main Components

Background: Sampling methods are one of the main components of each research. Familiarity with a variety of sampling methods is essential for researchers. Objective: The main purpose of this study was to teach different probabilistic and non-probabilistic sampling methods to improve the knowledge of researchers in conducting more accurate research. Methods: In this tutorial article, useful information about each sampling method, as well as how to properly use each method and its strengths and weaknesses are provided. Results: Five cases of probabilistic sampling methods and four cases of non-probabilistic sampling methods that are common are mentioned. Probabilistic sampling included simple random sampling, stratified random sampling, cluster sampling, systematic random sampling, and multi-stage random sampling. In addition to introducing each method, its strengths and weaknesses are also mentioned. Conclusion: Probabilistic sampling methods despite limiting assumptions provide more reliable results. Therefore, if it is possible, researchers should use probabilistic sampling methods to increase the accuracy of the study.

Abstract Objective: To estimate the prevalence of thinness, overweight and obesity among Tibetan adolescents aged 12-17 years. Design: Cross-sectional survey. Setting: Shigatse city of Tibet municipality, with an average altitude of more than 4000 m. Subjects: Study participants included 2,642 adolescents aged 12-17 years selected from 6 schools using a convenient cluster sampling method. Results: The prevalence of thinness/overweight/obesity among Tibetan adolescents was 9.4%/5.4%/1.4% (China definition), 14.7%/4.4%/0.7% (IOTF definition), and 2.8%/5.7%/0.9% (WHO definition). The prevalence of thinness and overweight was significantly different between both sexes based on each of three BMI classification criteria (P <0.001). There was no significant difference in the prevalence of obesity between both sexes according to each of three BMI criteria. There was no clear trend in the prevalence of thinness across ages according to the China or IOTF definition (both P >0.05), whereas an upward trend was observed for thinness in boys according to the IOTF definition (P for trend <0.05). In contrast, the prevalence of thinness tended to decrease with increasing age in girls according to the IOTF definition, and in total sample according to the WHO definition (P for trend <0.05). Conclusions: Among Tibetan adolescents, the prevalence of overweight and obesity is relatively low, while the prevalence of thinness is high, especially in boys. These data suggest urgent attention is needed to control adolescent thinness in Tibet.

<p>Artikel ini bertujuan untuk menganalisis dan menginterpretasi pengaruh model kepercayaan publik terhadap kepatuhan wajib pajak di Provinsi Sulawesi Selatan. Pendekatan penelitian menggunakan analisis kuantitatif dengan metode survey di tiga area Kantor Pelayanan Pajak yaitu Makassar Selatan, Maros, dan Palopo. Populasi dalam penelitian ini adalah wajib pajak  yang telah teregistrasi sebagai wajib pajak, baik pajak orang pribadi dan pajak badan sebanyak 2400 orang. Sampel penelitian menggunakan multistage cluster sampling methods untuk memastikan keterwakilan populasi. Penarikan sampel menggunakan metode stratified random sampling terhadap tiga area penelitian. Rumus Slovin digunakan untuk menetapkan jumlah sampel  sebesar 20% dengan pertimbangan karena populasi yang relatif besar dimana persentase kelonggaran ketelitian kesalahan pengambilan sampel yang masih  bisa ditolerir sebesar α=0,05. Dengan dasar tersebut, maka sampel dalam penelitian ditetapkan sebanyak 400 responden. Teknik analisis data menggunakan teknik analisis kuantitatif dengan menggunakan persamaan model struktural. Hasil penelitian ini menunjukkan bahwa kepercayaan publik berpengaruh positif dan signifikan terhadap kepatuhan wajib  pajak. Kepercayaan publik berpengaruh positif dan signifikan terhadap kepatuhan wajib pajak melalui kinerja pelayanan pajak. Variabel kinerja pelayanan pajak berpengaruh positif dan signifikan terhadap kepatuhan wajib pajak. Faktor pemerintah, faktor resiko, dan faktor kontekstual berpengaruh positif dan signifikan terhadap kepercayaan publik dalam meningkatkan kepatuhan wajib pajak di Provinsi Sulawesi Selatan. </p><p><strong>Kata kunci : Kepercayaan publik, kinerja pelayanan pajak, kepatuhan wajib pajak</strong></p>
