Abstract

Kinerja conveyor dalam proses produksi suatu industri sangat berpengaruh dalam mengoptimalkan hasil produksi. Penggunaan conveyor tidak terlepas dengan motor penggerak conveyor, sehingga kondisi prima motor juga harus diperhatikan agar proses produksi tidak terhenti yang mengakibatkan kerugian yang relatif besar bagi industri yang memiliki tingkat produksi tinggi. Untuk mengetahui dan menentukan kondisi dari motor – motor yang akandibebani dalam kondisi baik maka digunakan logika fuzzy. Logika fuzzy harus dioptimalkan penggunaanya dengan Algoritma genetika dalam menentukan nomor motor berapa saja yang harus hidup sehingga sesuai dengan beban yang dipikul. Menetukan dan mengetahui kondisi motor dan menentukan nomor motor yang harus beroperasi bertujuan untuk mengoptimalkan berjalannya suatu sistem conveyor.

Abstract

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.

Abstract

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.

Abstract

The ant colony algorithm is an algorithm adopted from the behavior of ants which naturally ants are able to find the shortest route on the way from the nest to places of food sources based on footprints on the track that has been passed. The ant colony algorithm helps a lot in solving several problems such as scheduling, traveling salesman problems (TSP) and vehicle routing problems (VRP). In addition, ant colony has been developed and has several variants. However, in its function to find the shortest distance is optimized by utilizing several normalized distance formulas with the data used in finding distances between merchants in the mercant ecosystem. Where in the test normalized distance is superior Hamming distance in finding the shortest distance of 0.2875, then followed by the same value, namely the normalized formula Manhattan distance and normalized Euclidean distance with a value of 0.4675 and without using the normalized distance formula or the original ant colony algorithm gets a value 0.6635. Given the sensitivity in distance search using merchant ecosystem data, the method works well on the ant colony Algorithm using normalized Hamming distance.

Abstract

Perkembangan teknologi informasi dan internet saat ini telah mengubah cara manusia dalam melakukan komunikasi. Salah satunya adalah perkembangan media sosial, media sosial sudah menjadi bagian dari kehidupan untuk memperoleh, membagikan dan menyebarluaskan informasi. Semakin berkembangnya media sosial maka masalah keamanan informasi dan privasi juga menjadi hal yang penting saat ini. Media sosial sebagai salah satu sumber bocornya informasi rahasia sudah menjadi hal yang umum saat ini. Tanpa disadari, banyak data mengenai privasi seseorang yang telah bocor di internet. Data privasi yang tersebar bisa disebabkan oleh kelalaian maupun penyedia layanan. Keamanan sistem informasi merupakan aset yang harus dilindungi keamanannya. Keamanan secara umum diartikan sebagai “quality or state of being secure to be free from danger”. Metode penelitian dilakukan adalah menggunakan metode blended. Penelitian ini dilakukan dengan cara  mencari dan serta memahami literatur atau yang berhubungan keamanan informasi pada media social dan penelitian pustaka. Enam poin utama yang harus dipertimbangkan saat menggunakan sistem aplikasi online terkait privasi data yaitu  keamanan dan data perlindungan, kesadaran pengguna, pengaturan kontrol, manajemen risiko, transparansi, dan etika. Perlu dibangun kepercayaan ke dalam rancangan layanan Internet, baik melalui kegiatan rancang bangun pengelolaan suatu sistem yang lebih mengedepankan user priority.  Memungkinkan, user diberikan pilihan mekanisme kontrol terhadap perlu tidaknya dalam mengungkapkan informasi pribadi dan penggunaannya.

Abstract

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. The sample in this study was the entire population, namely mothers who have babies aged 0-12 months in Barbaran Jae Village, Kec. Panyabungan Barat as many as 31 people. The highest frequency distribution was found in sufficient knowledge, namely 17 respondents (54.8%), multipara parity, namely 19 respondents (61.3%), academic education/PT, namely 13 respondents (41.9%), and sources of information print media that is 17 respondents (54.8%).

Abstract

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.
