    Paper ini berisi tentang kajian pengaruh shift kerja terhadap beban kerja pekerja denganmenggunakan metode SWAT. Permasalahan dalam penelitian ini adalah PT Toyota MotorManufacturing Indonesia (TMMIN), mempunyai ketetapan Zero Accident dalam setiapkegiatan produksi maupun kegiatan bekerja. sehingga Perusahaan dihadapkan denganmasalah bagaimana memenuhi ketetapan Zero Accident tersebut. Aspek keselamatan dankesehatan kerja sangat perlu diperhatikan, agar tercipta kondisi kerja yang baik sehinggadidapatkan output yang optimal. Jam kerja karyawan produksi PT TMMIN terdapat 2 shiftkerja (red dan white), PT TMMIN Penelitian ini bertujuan untuk mengetahui apakah terjadiperbedaan beban kerja mental terhadap shift kerja sebagai faktor penunjang kesehatan dankeselamatan kerja karyawan line AA di PT. Toyota Motor Manufacturing Indonesia denganmenggunakan Metode SWAT. Metode yang digunakan dalam penelitian ini adalah MetodeSWAT. Metode SWAT merupakan metode pengukuran beban mental secara subjektif yangdidasarkan pada persepsi pekerja, dengan menggunakan kombinasi dari tiga dimensi dengantingkatannya.Dimensi tersebut adalah beban waktu, beban USAha mental dan beban tekananpskologis. SWAT sebagai sebuah skala multidimensional melakukan 2 (dua) tahapanpekerjaan, yaitu : pembuatan skala dan pemberian nilai terhadap hasil penelitian.Pengujiandata kuesioner menggunakan Uji Anova hasil nilai probabilitas sebesar 0,213. Karena nilaiprobabilitas lebih besar dari 0,05 maka data tersebut dinyatakan tidak terdapat perbedaanyang signifikan dari beban kerja terhadap shift kerja. Dapat disimpulkan bahwa rata-ratabeban kerja mental shift pagi dan shift malam hanya terjadi perbedaan sebesar 19%, dantepatnya beban kerja shift malam lebih tinggi dibandingkan beban kerja shift pagi

    Improving Retrieval Performance of Case Based Reasoning Systems by Fuzzy Clustering

    Get PDF
    Case-based reasoning (CBR), which is a classical reasoning methodology, has been put to use. Its application has allowed significant progress in resolving problems related to the diagnosis, therapy, and prediction of diseases. However, this methodology has shown some complicated problems that must be resolved, including determining a representation form for the case (complexity, uncertainty, and vagueness of medical information), preventing the case base from the infinite growth of generated medical information and selecting the best retrieval technique. These limitations have pushed researchers to think about other ways of solving problems, and we are recently witnessing the integration of CBR with other techniques such as data mining. In this article, we develop a new approach integrating clustering (Fuzzy C-Means (FCM) and K-Means) in the CBR cycle. Clustering is one of the crucial challenges and has been successfully used in many areas to develop innate structures and hidden patterns for data grouping [1]. The objective of the proposed approach is to solve the limitations of CBR and improve it, particularly in the search for similar cases (retrieval step). The approach is tested with the publicly available immunotherapy dataset. The results of the experimentations show that the integration of the FCM algorithm in the retrieval step reduces the search space (the large volume of information), resolves the problem of the vagueness of medical information, speeds up the calculation and response time, and increases the search efficiency, which further improves the performance of the retrieval step and, consequently, the CBR system

    This research attempt to test and compare three type of measurement technique in measuring brandimage and brand quality: rating, ranking, and pick any. The objective of this research is to test theconsumer consistency in their perception and attitude toward brand image and brand quality usingthree different measurement techniques. This research were replication Barnard & Ehrenberg (1990)and Driesener & Romaniuk (2006) which compare the compare three type of measurement technique inmeasuring brand image.There are three shampoo products acting as the research objects in this research: Clear, Dove, andPantene. Acting as the respondent for this research was 149 consumers who had use that three brandof shampoo. Data analysis were execute using mean score for rating technique, score order for rankingtechnique, and mode score for pick any technique.Results show that (a) measurement in brand image using rating, ranking, and pick any technique didnot show the same score and respondent have tendency to answer the questions inconsistently. (b)Measurement using rating and pick any techniques show consistent result

    OBJECTIVE: Learning basic vascular examination is a complex process. Very few studies have focused on the ability to measure the arterial systolic blood pressure at the ankle (ASBPa). The aim of this study was to objectively assess the effects of a 1-h practical educational intervention on the ability to measure ASBPa among medical students. METHODS: A total of 27 medical students were prospectively recruited. Two evaluation sessions of ASBPa measurement skills were conducted, before (T1) and after a 1-h practical lesson (T2). To assess the learning effect associated to the simulator-based evaluation, a control group composed by nonmedical students, not involved in the practical lesson, was also tested. Objective assessments of ASBPa measurements were performed by an instrumented leg prototype. RESULTS: There was a nonsignificant decreasing trend measurement time after practical lesson. The average pressure determination error (ΔP) was significantly reduced: ΔPT1: 10.5 ± 13.8 mmHg vs. ΔPT2: 5.7 ± 6.0 mmHg (P = 0.002). The mean deflation rate (DR) of the cuff was significantly decreased: DRT1: 12.9 ± 9.2 mmHg/s vs. DRT2: 8.7 ± 4.6 mmHg/s (P = 0.001). The control group did not show significant changes. CONCLUSION: A 1-h practical learning could improve some parameters of the ASBPa measurement among medical students, but was not sufficient to allow the measured technical factors to reach established guidelines
