Abstract— PD Tahu Al-Barokah is a company engaged in the production of tofu by utilizing soybeans as its main raw material. This company is one company that actively produces tofu every day to meet consumer demand, especially in the district of Cianjur. The problem in PD. Know Al-Barokah is the high level of work accidents in the production department. Where this study aimed to find out how much influence the level of work accidents on meeting production targets. The method used in this study is linear regression. The results of the correlation / relationship value (R) of 0.779 obtained the output obtained a coefficient of determination (R Square) of 0.607 which means that the influence of the work accident variable on the variable fulfillment target of 60.7%. Abstrak— PD Tahu Al-Barokah merupakan perusahaan yang bergerak dibidang produksi tahu dengan memanfaatkan kedelai sebagai bahan baku utamanya. Perusahaan ini merupakan salah satu perusahaan yang aktif memproduksi tahu setiap harinya untuk memenuhi permintaan konsumen khususnya di kabupatun cianjur. Permasalah yang ada di PD Tahu Al-Barokah yaitu  adanya kecelakaan kerja pada bagian produksi, yang diprediksi menjadi penyebab tidak tercapainya target pemenuhan produksi. Penelitian ini ditujukan untuk mengetahui seberapa besar pengaruh tingkat kecelakaan kerja terhadap pemenuhan target produksi. Metode yang digunakan pada penelitian ini yaitu regresi linier.

Three different modeling approaches were applied to explain truck accidents at interchanges in Washington State during a 27-month period. Three models were developed for each ramp type including linear regression, neural networks, and a hybrid system using fuzzy logic and neural networks. The study showed that linear regression was able to predict accident frequencies that fell within one standard deviation from the overall mean of the dependent variable. However, the coefficient of determination was very low in all cases. The other two artificial intelligence (AI) approaches showed a high level of performance in identifying different patterns of accidents in the training data and presented a better fit when compared to the regression model. However, the ability of these AI models to predict test data that were not included in the training process showed unsatisfactory results.

ABSTRACTPT. Palm Lampung Persada Way Kanan is a company engaged in oil palm plantations that produce crude palm oil. This company often experiences problems in the allocation of palm oil production.This research was conducted using multiple linear regression method to predict the allocation of the amount of palm oil production based on learning data using Microsft Excel 2010 and RapidMiner applications. In this study there are dependent variables (free) and independent variables (bound), namely: dependent variable (raw material, amount of labor, rainfall and land area) while the independent variable (palm oil).Calculations using multiple linear regression methods in determining the allocation of the amount of palm oil production can be used to assist companies in making a decision with predictive value close to the original data processed as learning data with a result of 170.811 and original data of 170 and an error value of 0.002.

Bullwhip effect is the main evidence of inefficiency in the supply chain of a company. Bullwhip effect describes the tendency of increasing the number of purchases of raw material supply chain<br />as a result of the inability to predict the increase in the number of requests. This study is the high level of inventory, whether as a result of the bullwhip effect or was due to an increase in demand. The purpose of this study was to determine the contribution of each factor causes of the bullwhip effect, identify the factors that provide the greatest impact on supply chain performance and find solutions to reduce the impact caused. The approach of this research is done by collecting data for inventory movement in the period 2003-2007, analyzing the interaction between members in the supply chain. Theory - the theory was used to create a research model. Data analysis is done by analyzing graphs and statistical analysis for the right to draw conclusions from this research. Results from this study that the coordination of “end to end” supply chain to reduce the impact of<br />bullwhip effect in supply chain

PT Matahari Department Store Tbk is a company engaged in selling retail fashion’s apparel. One of the management’s functions performed in Matahari Department Store Bandung Indah Plaza is controlling function. By the area of 5700m2 and a large number of employees, it’s such an obstacle for the supervisor/coordinator to oversee every employee. So many employees are not doing a good job. This issue caused fluctuations in employee productivity from July to December 2013. Therefore, this study aims to determine the level of controlling, employee productivity levels and influence levels between controlling and employee productivity in Matahari Department Store Bandung Indah Plaza. The population in this study consisted of an employee which are permanent employees and suppliers of amount 498 people, with a research sample of 120 employees. In this study, the method of analysis used is descriptive analysis, correlation and simple linear regression. According to this study result, controlling and employee productivity is at a good level. Controlling contribute to affect employee work productivity by 16,5% obtained from the coefficient of determination, while 83.5% were influenced by the contributions of other factors which is not explained in this research. The correlation value of 0.407 indicates a moderate relationship between controlling and employee productivity.

PT. Asam Jawa is a company operating in the oil palm sector as an object that we make to conduct research. Research or research is carried out to evaluate and test whether there is an influence or impact of competence, discipline, and career development on employee performance at PT. Asam Jawa, the city of Medan. Where the multiple Linear Regression analysis method that researchers use in this study, this method is a linear regression model that involves more than one independent variable or hypothesis. With the population taken, namely all employees, the number is 45 employees. And testing the sample of researchers in the study is to use saturated sampling where all employees of PT. Asam Jawa, Medan, which used as a sample of 45 respondents and 30 respondents as a test of validity and reliability of PT. Perkebunan Nusantara III.

Inflation and Growth in the company's profit margin than Food and Beverages. Analysis tools used in this study is panel data regression, a combination of two data time series and cross section can provide more data so that it will generate degree of freedom (df) is greater, to determine the effect between inflation and growth in production cost profit margin ratio. Based on the conclusion, it can be concluded that the rate of inflation and growth in production costs affect the level of corporate profit margins at the Food and Beverages during the period 2005-2008 with a coefficient of determination equal to 96.83%. Partially between the inflation rate did not negatively affect the profit margin between the rate of inflation while the growth rate positively affects the production cost. So that can be implicated to obtain a high level of profit margin, then for company management to pay more attention to the level of growth in production costs, such as looking for suppliers who provide raw material prices are much cheaper so that more efficient control of production costs.
