Currently, almost one million children each year do not receive an immunization program. 2007 data shows that only 6 out of 10 children in Indonesia receive a complete immunization program. In fact, 9 out of 100 children do not get vaccinated at all. The percentage of children who received complete vaccination for DPT was only 66.7%. The immunization percentage for hepatitis B was 60.3%; for tuberculosis 85.4%, for Polio 73.5%, and for measles 76.4%. This type of research used an analytic study with a cross sectional design, which aims to explain the relationship between parity, education and sources of information with the level of mother's knowledge about the completeness of basic immunization. Data analysis was done by chi square test. The population in this study were all mothers who had babies aged 0-12 months in Barbaran jae village, kec. West Panyabungan as many as 31 people.

Mathematics and philosophy are two words with different meanings and the same thing. With various historical evidence, mathematics as the basis of science is not part of or born from philosophy. In the same position in knowledge, mathematics confirm the answers to intimate problem in philosophy. Often there is confusion in philosophy because of conflicting concepts with one another. Mathematics without philosophy does not move swiftly, because without the meanings that are sometimes driven by philosophy. Logically, truth is not well developed in evidence except when mathematics and philosophy get long. It is to provide an understanding of the need for a foundation of truth thought, which generally reveals in the comprehension of mathematics, namely in meta-mathematics and philosophy.

Self-Organizing Map (SOM) is an unsupervised artificial neural network algorithm. Even though this algorithm is known to be an appealing clustering method,many efforts to improve its performance are still pursued in various research works. In order to gain faster computation time, for instance, running SOM in parallel had been focused in many previous research works. Utilization of the Graphics Processing Unit (GPU) as a parallel calculation engine is also continuously improved. However, total computation time in parallel SOM is still not optimal on processing large dataset. In this research, we propose a combination of Dynamic Parallel and Hyper-Q to further improve the performance of parallel SOM in terms of faster computing time. Dynamic Parallel and Hyper-Q are utilized on the process of calculating distance and searching best-matching unit (BMU), while updating weight and its neighbors are performed using Hyper-Q only. Result of this study indicates an increase in SOM parallel performance up to two times faster compared to those without using Dynamic Parallel and Hyper-Q.

The COVID-19 pandemic that has recently hit various countries including Indonesia has resulted in major changes in various fields, including in the development of the education sector. The teaching and learning process has turned from face-to-face into an online method. However, there are several obstacles experienced by schools that implement an online learning system, one of them was the ability of teachers who do not understand various learning application platforms. In addition, the material provided by the teacher is not maximally acceptable to students because most teachers provide learning material from the pages of textbooks or teacher writings (scans, photos, or presentation files). For this reason, it is necessary to have variations in the provision of teaching materials to students by making interesting and creative learning videos using the Movavi Education Set. With learning videos, students can do lessons at home, repeat it, and can ask the teacher some points from it if they don't understand. By using Movavi Education Set, teachers are also free to be creative in making learning videos that can be shared through commonly used communication applications such as e-mail, WhatsApp, line, google classroom and other applications.

Forecasting involves all areas in predicting future events. Many problems can be solved by using a forecasting approach to become a study in the field of data science. Forecasting that learns through data in the light age is able to solve problems with large-scale data or big data. With the big data, the performance of the k-Nearest Neighbor (k-NN) method can be tested with several accuracy measurements. Generally, accuracy measurement uses MAPE so it is necessary to conduct sensitivity on MAPE by combining it with the detection rate which is the difference technique. In addition, the k-NN process has been developed for the sake of running sensitivity by performing normalized distance using normalized Euclidean distance so that in this paper using the crude palm oil (CPO) price dataset, it is able to forecast and become a future model and apply it to Business Intelligence and analysis. In the final stage of this paper, the accuracy value in doing big data forecasting on CPO prices with MAPE is 0.013526% and MAPE sensitivity combined with a detection rate of 0.000361% so that future processes using different methods need to involve detection rates.

Logika adalah metode atau teknik yang diciptakan untuk meneliti ketepatan penalaran serta mengkaji prinsipprinsip penalaran yang benar dan penarikan kesimpulan yang absah. Ilmu logika berhubungan dengan kalimatkalimat (argumen) dan hubungan yang ada diantara kalimat-kalimat tersebut. Tujuannya adalah memberikan aturan-aturan sehingga orang dapat menentukan apakah suatu kalimat bernilai benar. Kalimat yang dipelajari dalam logika bersifat umum, baik bahasa sehari-hari maupun bukti matematika yang didasarkan atas hipotesahipotesa. Oleh karena itu aturan-aturan yang berlaku di dalamnya haruslah bersifat umum dan tidak tergantung pada kalimat atau disiplin ilmu tertentu. Ilmu logika lebih mengarah dalam bentuk sintaks-sintaks daripada arti dari kalimat itu sendiri. Secara umum logika dibedakan menjadi dua yaitu Logika Pasti dan Logika Tidak Pasti. Logika pasti meliputi Logika Pernyataan (Propotitional Logic), Logika Predikat (Predicate Logic), Logika Hubungan (Relation Logic) dan Logika Himpunan. Sedangkan logika tidak pasti meliputi Logika Samar atau kabur (Fuzzy Logic). Logika Pernyataan membicarakan tentang pernyataan tunggal dan kata hubungnya sehingga didapat kalimat majemuk yang berupa kalimat deklaratif. Logika Predikat menelaah variabel dalam suatu kalimat, kuantifikasi dan validitas sebuah argumen. Logika Hubungan mempelajari hubungan antara pernyataan, relasi simetri, refleksif, antisimtris, dll. Logika himpunan membicarakan tentang unsur-unsur himpunan dan hukum-hukum yang berlaku di dalamnya.

To classify Naïve Bayes classification (NBC), however, it is necessary to have a previous pre-processing and feature extraction. Generally, pre-processing eliminates unnecessary words while feature extraction processes these words. This paper focuses on feature extraction in which calculations and searches are used by applying word2vec while in frequency using term frequency-Inverse document frequency (TF-IDF). The process of classifying words on Twitter with 1734 tweets which are defined as a document to weight the calculation of frequency with TF-IDF with words that often come out in tweet, the value of TF-IDF decreases and vice versa. Following the achievement of the weight value of the word in the tweet, the classification is carried out using Naïve Bayes with 1734 test data, yielding an accuracy of 88.8% in the Slack word category tweet and while in the tweet category of verb 78.79%. It can be concluded that the data in the form of words available on twitter can be classified and those that refer to slack words and verbs with a fairly good level of accuracy. so that it manifests from the habit of twitter social media user.
