This study aimed to determine the workload of the workers to be used for incentive plan in the Quality Control Division, Company X. Studying work characteristics, a work sampling technique was used. Two workers from this QC division were participated in the study. A number of 440 observation were taken from each Worker 1 and Worker 2. Results showed that the percentages of productive time are 93.62% for Worker 1 and 91.81% for Worker 2. Meanwhile for workload resulted 151% and 138% for Worker 1 and Worker 2 (classified as overload for both workers). This study recommended the company to add one more worker to help in this workstation to reduce the workload of these two workers

This study aims to determine the utilization of the worker’s time in the filling process, packaging department, a cup and bottled water company. Considering the aim of the study and the task characteristics, work sampling technique was used. Two production lines and two work stations were selected for time studyanalysis. In each work station, two workers with different tasks were involved for the time analysis. A number 586 and 1710 observations from Worker 1 in Line 1 and Line 2, and 586 and 1440 observations from Worker 2 in Line 1 and Line 2 were taken and observed. Results showed that the utilization of worker’s time are 31.7% and 33.6 % of Worker 1 in Line 1 and Line 2, and 25.6% and 21.0% of Worker 2 in Line 1 and Line 2. Results of significant testing showed that no significant differences were found for workers’ time utilization between Worker 1 in Line 1 and Worker 1 in Line 2 (Z=-0.82, p=0.41) and between Worker 2 in Line 1 and Worker 2 in Line 2 (Z=2.17, p=0.03) for α=0.01. Regarding findings in this study, it is reasonable for the management to consider work station which one worker per machine instead of two workers per one machine.

Data Problem

Abstract Background Mass spectra are usually acquired from the Liquid Chromatography-Mass Spectrometry (LC-MS) analysis for isotope labeled proteomics experiments. In such experiments, the mass profiles of labeled (heavy) and unlabeled (light) peptide pairs are represented by isotope clusters (2D or 3D) that provide valuable information about the studied biological samples in different conditions. The core task of quality control in quantitative LC-MS experiment is to filter out low-quality peptides with questionable profiles. The commonly used methods for this problem are the classification approaches. However, the data imbalance problems in previous control methods are often ignored or mishandled. In this study, we introduced a quality control framework based on the extreme gradient boosting machine (XGBoost), and carefully addressed the imbalanced data problem in this framework. Results In the XGBoost based framework, we suggest the application of the Synthetic minority over-sampling technique (SMOTE) to re-balance data and use the balanced data to train the boosted trees as the classifier. Then the classifier is applied to other data for the peptide quality assessment. Experimental results show that our proposed framework increases the reliability of peptide heavy-light ratio estimation significantly. Conclusions Our results indicate that this framework is a powerful method for the peptide quality assessment. For the feature extraction part, the extracted ion chromatogram (XIC) based features contribute to the peptide quality assessment. To solve the imbalanced data problem, SMOTE brings a much better classification performance. Finally, the XGBoost is capable for the peptide quality control. Overall, our proposed framework provides reliable results for the further proteomics studies.

Boiled fish is a processing of fishery products that have great potential because of high public demanding. UMKM Cindy Group is a small and medium enterprise in Bogor regency who wished that their product could be competitive, so that the application of quality management is required. The objectives of this research were: (1) to identify the level of quality management implementation at traditional and hygienic boiled fish SMEs as well as; (2) to analyze the relation of the level of quality application to the performance of traditional and hygienic boiled fish SMEs. The method used was descriptive analysis; trend analysis (financial performance: Net Profit Margin (NPM), Return on Investment (ROI), Return on Equity (ROE) and non-financial performance (number of training, production volume, number of customers); and discriminant analysis. Sampling technique for filling questionnaire was purposive sampling. The results of the study found that the level of application of quality management system at traditional boiled fish was at the level between Quality Control Operator (OQC) and Foreman Quality Control (FQC), while hygienic cleansing was at the level between Statistic Quality Control (SQC) and Total Quality Management (TQM). The result of discriminant analysis show that the level of SMM implementation has an effect on the company performance of UD Cindy Group that was seen from sig value <0.05. On hygienic displacement had an increasing trend of non-financial performance and higher on the average of the last three years compared with traditional boiled fish

The purpose of this study is to develop simple and cost-effective Fourier transform infrared (FT-IR) methods for quality control evaluation of repaglinide (RPG), rosiglitazone maleate (RGZ), pioglitazone hydrochloride (PGZ) and metformin hydrochloride (MET) and assess their use for in-process quality control and detection of counterfeit medicine. The conventional KBr disc sampling technique used in FT-IR does not result in constant path-length thus impeding the use of this sensitive and simple technique for quantification of drugs. In this study, FT-IR quantitative assays were developed using a constant KBr disc pathlength to quantify drugs in bulk and tablets. Method validation was done according to the International Conference on Harmonization (ICH) guidelines and recovery studies were performed by applying standard addition technique. Samples representing pitfalls at different tablet manufacturing stages and counterfeit medicines were prepared and tested by FT-IR. The developed methods achieved ICH validation parameters. Statistical comparison of the results with reference or reported methods showed no significant difference with respect to method accuracy and precision. The methods were applicable to tablet dosage form with average recovery ranging between 99 and 102%. The developed methods are capable of detecting impurities that result from in-process manufacturing problems and counterfeit products and are inclusive for in-process and end product testing.

The growing demand and the degree of patient care in oncological outpatient services, as well as the complexity of treatment have had an impact on the workload of nurses. This study aimed at measuring the workload and productivity of nurses in an oncological outpatient service. An observational study using a work sampling technique was conducted and included seven nurses working in an oncological outpatient service in the south-eastern region of Brazil. A total of 1,487 intervention or activity samples were obtained. Nurses used 43.2% of their time on indirect care, 33.2% on direct care, 11.6% on associated activities, and 12% on personal activities. Their mean productivity was 88.0%. The findings showed that nurses in this service spend most of their time in indirect care activities. Moreover, the productivity index in this study was above that recommended in the literature.
