Abstract

Employee performance is the level of success of employees in carrying out their duties. Factors that influence employee performance are training and discipline. Training is an activity prepared by management to improve the employees’ skills and abilities to produce high performance. Discipline is the awareness and availability of a person to obey all applicable rules and social norms. The employee’s performance decreases due to the poor discipline and inappropriate training programs. PT. Sany Toga Gemilang is engaged in the plastic industry. The research method used is a quantitative approach, the type of research used is quantitative descriptive. Data collection is done by having interviews, questionnaires and documentation studies. Analysis of the data used is multiple linear regressions. The population is all employees (186 people). Slovin formula was used in determining the research sample, where 127 people were obtained as the study sample, while for testing the validity taken a sample of 30 people outside the study sample. The results showed that training and discipline simultaneously and partially have a positive and significant effect on employee’s performance with a determinant coefficient of 0.767 or 76.7%, while the remaining 23.3% was not examined. The conclusion of the study is that simultaneously and partially training and discipline have a significant effect on employee’s performance at PT. Sany Toga Gemilang.

Abstract

The accuracy of the results of a forecasting method is the main consideration for using the forecasting model in statistical decision making. The size of the accuracy can be seen from the percentage of errors generated by the forecasting model. There are various forecasting methods in statistics, where one of them is the autoregressive first order or AR (1) model, this model is known to be good enough to predict a random process value in a short period of time, but by applying the Ensemble Kalman Filter method to forecasting methods this is expected to produce more accurate results. In this paper it will be shown that the Ensemble Kalman Filter (EnKF) technique can improve the forecasting results.

Abstract

This study aims at determing the response of growth and production of peleng vegetables to the application of liquid organic fertilizer in various mulch. The study was conducted on land located in Simalingkar A Medan with a height of ± 32 m above sea level, began from May to August 2017. The research method used a factorial randomized block design with 2 factors. The first factor is the dose of NASA liquid organic fertilizer (P) which consists of 3 levels of treatment, namely: P0 = control, P1 = 3 ml / l water and P2 = 6 ml / l water. The second factor is the provision of mulch (M) which consists of three types, namely: M0: without mulching, M1: rice straw mulch and M2: black silver plastic mulch (MPHP). The results showed that the treatment of NASA liquid organic fertilizer up to 6 ml / l water significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but differed not markedly on the relative growth rate of plants. The treatment of organic mulch and black silver mulch significantly increased plant height, number of leaves, fresh weight of plants per sample, fresh weight of plants per plot, dry weight of plants per sample and dry weight of plants per plot, but not significantly different to the relative growth rate of plants. The interaction between NASA's liquid organic fertilizer treatment and mulch administration had no significant effect on plant height, number of leaves, plant fresh weight per sample, plant fresh weight per plot, plant dry weight per sample, plant dry weight per plot and relative plant growth rate

Abstract

Interpolate for function of several variables or multivariate data is still very limited discussed in literature. Would be very useful if help who compares the result of both scheme interpolate whether deterministic and stochastic. Lagrange method is one of the deterministic interpolaton scheme who determine a polynomial function to approach sample data, while Ordinary Kriging is one of the scheme stochastic interpolation who use the parameter of statistic sample data in neighbor point that will be interpolate. Both this scheme have the same result that very fine in interpolate points on multivariate data, although both of this method need different sample size.
