Abstract

Batik is the result of cultural arts that contains a philosophical meaning in each of its motifs. Various types of batik motifs create complexity in the recognition of batik image patterns. Classification of images into certain classes is also a problem in the field of pattern recognition. Machine learning is a method that is very developed at this time. Machine learning method is used to identify batik motifs through batik image classification. This study focuses on the image dataset of written batik which has two motifs, namely classical motifs and contemporary motifs. This study shows the experimental results of batik image classification using the Backpropagation Neural Network, Support Vector Machine and k-Nearest Neighbor classification methods. Co-occurrence matrices as wavelet filter-based feature extraction are used for input into batik image classification. The experimental results show that k-NN gets the best accuracy value of 95.56% while BPNN gets an accuracy value of 85.40% and SVM gets an accuracy value of 76.51%. Based on these results, it can be concluded that k-NN is the best method for classifying batik images with co-occurrence matrices as wavelet filter-based feature extraction.

Abstract

The Semarang Outer Ring Road (SORR) project which is located on soft soil has the potential to experience land subsidence due to consolidation. The consolidation settlement is predicted to continue along with the length of time the consolidation is completed. It is necessary to study subsurface engineering geology to obtain an overview of the structure of the soil layers and the thickness of the soft soil layer that has the potential to undergo consolidation. Based on the data of 4 borehole points and the results of laboratory tests, evaluation and correlation were carried out to obtain the stratigraphy of the soil layer. The stratigraphic results showed that the total depth of the soil investigation was 50 m, with the surface soil layers generally consisting of embankment soil, sandy clay, sandy silt, and clayey silt. The distribution of clay and silt with very soft to medium consistency dominates the soil layer structure with a thickness varying between 15.50-28.00 m. This condition has the potential to cause an increase in the magnitude and rate of consolidation due to the surface loading of the embankment soil.

Abstract

There are problems faced by chicken farmers, namely how to improve chicken yields so that it will impact on improving the welfare of members of chicken farmers. One of them is how chicken feed can be routinely and scheduled. Currently the method used for chicken feed is by manual means of sprinkling chicken feed / pellets routinely both morning and evening, so that it has an obstacle that is sometimes the chicken breeder is forgetful or late in feeding the chicken so that it will affect the growth of the chicken. This can result in late harvest days and yields are not optimal because the chicken weight is not optimal. The purpose and objective of this activity is to obtain an appropriate technology design for making chicken feed equipment automatically so that chicken feed can be carried out routinely and on a scheduled basis. The results of this activity are obtained the design of appropriate automatic chicken feed tools to help overcome the problems of chicken farmers in increasing chicken yields. It is expected that the chicken yield will be increased later than when feeding chicken is done manually.
