Abstract

Pada model pengukuran fisik beras masih menggunakan model pengukuran manual yaitu menggunakan micrometer dimana penggunaannya masih memerlukan waktu yang cukup lama dan hasil pengukurannya masih bersifat subjektif dikarenakan hasil pengukuran menggunakan micrometer. Bergantung juga kepada kemampuan penglihatan masing-masing individu yang melakukan pengukuran. Maka perlu adanya cara pengukuran yang lebih cepat dalam mengukur dimensi beras tanpa mengurangi tingkat akurasi dengan menggunakan teknologi pemprosesan citra. Tujuan penelitian adalah mendapatkan cara yang lebih cepat dibandingkan menggunakan micrometer dengan memanfaatkan teknologi pemrosesan citra sebagai alat bantu instrumen pengukuran yang dapat menampilkan nilai ukur yang jelas terbaca. Penelitian dilakukan menggunakan data beras dari BULOG Kota Tegal. Dilakukan pengukuran panjang dan lebar beras tersebut baik dengan caliper dan dibandingkan dengan hasil citra menggunakan digital microscope dengan bantuan coding pada MATLAB secara realtime dari ruang warna YCBCR menjadi RGB diubah ke grayscale. Hasilnya menunjukkan bahwa pengukuran dimensi beras berupa panjang dan lebar suatu beras dapat dilakukan dalam pemrosesan citra dan hasil klasifikasi beras berdasarkan ukuran panjang dan lebarnya diperoleh beras memiliki ukuran 6.67-7.50 mm yang merupakan bentuk panjang, dan bahwa dari 100 beras diperoleh klasifikasi beras berdasarkan dimensi untuk lebarnya berupa bulat dengan ukuran < 2 mm

Abstract

The difficulty of sentiment classification on this big data can be overcome using deep learning. Before the deep learning training and testing process is carried out, a word features extraction process is needed. Word2Vec as a word features extraction is often used in sentiment classification pre-training because it can capture the semantic meaning of the text by representing a similar vector for each word that has a close meaning. Word2Vec has three parameters that affect the model learning process namely architecture, evaluation method, and dimensions. This study aims to determine the effect of each Word2Vec parameter on deep learning performance in sentiment classification. The accuracy results of the deep learning model were evaluated to determine the effect of the Word2Vec parameter. The results of this study indicate that the three Word2Vec parameters have an influence on the performance of the deep learning model in sentiment classification. The combination of Word2Vec parameters that produces the highest average accuracy include CBOW (Continuous Bag of Word) architecture, Hierarchical Softmax evaluation method, and a dimension of 100. CBOW produces better performance, because it has slightly better accuracy for words that often appear and in this research dataset there are many words that often appear. Hierarchical Softmax shows better results because it uses a binary tree model which makes words that occur rarely will inherit the vector representation above them. The dimension with a value of 100 produces better accuracy because it is in line with the number of datasets of 10,000 reviews.

Abstract

The Internet era has had an impact in various sectors of human life. One is the economic sector. Economic transactions change from the traditional pattern (face to face) to online. The customer does not need to ask about the condition of an item to be purchased to a close friend or family, but simply by reviewing the product from the same buyer's comments. Products that get good reviews mean good quality. However, a problem arises if the comment data is very large and will make it difficult for customers to summarize the quality. Therefore, an automatic opinion mining system is required which can directly give conclusions about the quality of a product. This research makes an opinion mining system by applying the Naïve Bayes algorithm by taking a case study of facebook account Dugal Delivry. The measurement result with confusion matrix gives precision value of 88,89%, recall 80% and accuracy equal to 85%.

Abstract

Management and submission of legalization at the Harapan Bersama Polytechnic have not been computerized. The legalization process is carried out face-to-face by leaving legalized documents and returning them when the legalized documents are ready. This process is problematic because going to campus requires quite a long time, and there is no certainty or travel history from the management of legalized documents. The research objective is to build a legalization system to facilitate the process of implementing legalization in BAA units using the website-based waterfall method. This system validates alumni data in the form of NIM at registration, processes payments through payment gateways, pays for selected shipments, and tracks travel history from the submitted legalized documents. This system is called Simaleja, and there are two actors involved. As a result, the system runs according to the functions of the actors involved and has been tested. As for the results of the black box (actor) test, the system has been running according to the function of each actor, and the UI/UX usability results were obtained for 38 users, 82% of whom fall into the very good category.
