Abstract

Sofia Medika Clinic in terms of supply of alphamol drugs every month is always the same, because the clinic has not been able to predict the number of drugs that need to be provided. When the amount of drug inventory is in excess, it will result in fewer drug expiration dates and make the selling price of drugs cheaper. On the other hand, when the amount of drug supply is in short supply, it will have an impact on patient service or buyers who are considered disappointing and have an impact on the clinic. To assist clinics in reducing drug sales errors, a technology is needed in it using forecasting methods. Based on the existing sales data pattern, the forecasting method used is the Double Exponential Smoothing method, because the sales data is a trend with all p-values > 0,05 with the Dicky Fuller test (ADF-test). This study aims to build an Alphamol Drug Forecasting Information System at Sofia Medika Clinic with the Double Exponential Smoothing Method. The results of the alphamol drug sales forecasting application system using the Double Exponential Smoothing Method obtained MAD = 221,0925, MSE = 176693,3, and MAPE = 7,26%. which previously produced a value of 29% so that the results of this application can be used to predict the amount of alphamol drug sales that will be sold in the present and in the future.

Abstract

Seasoning is one of the most important elements in a dish. Indonesian herbs or spices have a very wide variety of types. Mistakes in choosing spices have a big effect on the taste of the dish. Image processing is a branch of science in the field of technology that can be used to recognize image objeks captured by the camera. This study will classify the types of spices that are almost similar, namely ginger, galangal, turmeric and kencur. The classification method used is K-Nearest Neighbor (K-NN). In this study we tested how to split training data and data testing, namely 66.7%: 33.33%, 75%: 25% and 90%: 10%. The sharing of training data and testing data uses 90%: 10% has the greatest average accuracy compared to other distribution methods. The selection of K = 3 or K = 5 has an average accuracy that is almost the same in all methods of split training data and testing data, namely 64.66%: 65%. At K = 1 it has a fairly high accuracy compared to the previous K, which is 73%.

Abstract

One of the triggers for the high rate of intellectual unemployment is due to poor career planning. Lack of skills and competencies makes students find it difficult to choose a career. After completing a higher education program, in many cases, students are not ready to face competition in the world of work, especially in the field of Information Technology which is constantly updated. This study aims to determine the effect of the future time perspective and career maturity of Information Systems Study Program students on their work readiness in the field of informatics. This study uses a quantitative approach, the sample is a student of the Information Systems Study Program with as many as 150 respondents. The measuring instrument used is the Future time perspective (FTP) scale, the Career Maturity Scale, and the Work Readiness scale. Data were analyzed using multiple linear regression and correlation to determine the effect of each variable. The results of the study showed that the influence of the two variables was 38%. The effective contribution of the Future time perspective to Work Readiness is 5%. Meanwhile, the effective contribution of the Career Maturity variable to Work Readiness is 33%. Thus it can be concluded that the Career Maturity variable has a dominant influence on the Job Readiness variable than the Future time perspective variable. Although the contribution of the Future time perspective variable is small, it provides a significant contribution for students because it provides a new discourse in considering their career readiness.

Abstract

Meat has high nutritional value which is widely consumed by humans. The content contained in meat includes protein, vitamins, minerals, fats, and other substances that are needed by the body so that it can carry out activities every. However, unfortunately not all people can distinguish these types of meat, because the texture and color are almost similar. This is also often used by irresponsible meat sellers by mixing these types of meat or with other types of meat to get a big profit. Even though not everyone can consume certain types of meat for reasons of illness. This research was conducted to compare the GLCM and LBP methods for image classification of meat types based on texture analysis. The types of meat images that are classified are goat meat, buffalo meat, and horse meat. Image data is taken manually using a digital camera the Nikon D3200. The image was taken at a distance of 20 cm. Data testing and training was carried out using the Support Vector Machine (SVM) method. The texture characteristics used are ASM, IDM, entropy, contrast, and correlation. The results of the image classification accuracy of goat, buffalo, and horse meat using the GLCM method were 75.6%. While the results of the classification accuracy using the LBP method amounted to 85,6%. Thus, the LBP texture feature extraction method is recommended for classification of meat types using texture characteristics.
