Abstract

Perkembangan teknologi telah memicu pergeseran mendasar dalam gaya hidup modern. Salah satu penerapan dalam teknologi yang saat ini banyak dikupas secara mendalam adalah rumah cerdas (smart home). Perangkat dari teknologi rumah cerdas sangat beragam sehingga sulit untuk menyelaraskan kinerja sistem yang dibuat. Hal tersebut diatasi dengan membagi sistem menjadi sub-sistem yang lebih kecil sehingga akan memudahkan dalam manajemen sistem yang dibuat. Hal itu disebut juga sebagai modular system. Adanya self-management devices sangat penting agar perangkat pada rumah cerdas dapat memanajemen dirinya sendiri. Pervasive devices merupakan istilah yang digunakan untuk perangkat yang meresap dalam kehidupan sehari-hari yang memberikan layanan serta kemudahan kepada penggunanya. Untuk mencapai hal itu, pervasive devices harus mampu bekerja secara mandiri. Penelitian ini merancang dan menerapkan sistem yang dapat mendeteksi adanya raspberry pi (pervasive devices) secara otomatis pada jaringan lokal dan secara mandiri sistem dapat menyiapkan serta menyediakan layanan dimana pengguna dapat menggunakan layanan tersebut yaitu kendali led melalui web browser. Teknologi atau metode komunikasi antara web browser dan raspberry pi yang digunakan adalah websocket, sedangkan antara raspberry pi dengan wemos sebagai mikrokontroler untuk led yaitu menggunakan socket UDP (User Datagram Protocol). Pengujian dilakukan dengan menghitung waktu penemuan (discovery time) untuk menemukan raspberry pi pada jaringan lokal serta waktu respon layanan (on off, dimming dan rgb). Dari hasil pengujian, waktu penemuan didapatkan rata-rata waktu sebesar 4,23 detik dan rata-rata waktu respon layanan sebesar 0,52 detik.

Abstract

The selection of recipes on digital recipes is now done manually by comparing recipes to get recipes that match the criteria. The selection of recipes manually is less effective because it takes a lot of time in the recipe selection process from a large number of recipes. Lack of information on where to buy ingredients is also a problem because finding the location of the providers of the required ingredients takes time and sometimes the information gets less precise so mistakes in finding the location of purchasing ingredients often occur. To overcome these problems, we need a decision support system that can solve the problem of choosing recipes and can provide location information to buy the materials needed for cooking. The recipe selection decision support system is implemented using Simple Additive Weighting (SAW) method in the selection of recipes equipped with location-based features to provide location information where to buy ingredients. The system runs on the Android platform to take advantage of location-based features (LBS) found on Android. The result of User Acceptance Testing (UAT) with calculation using Likert's Summated Rating (LSR) scaling technique obtained a total score of 804.

Abstract

Software Defined Network (SDN) is a network modeling separating control plane and data plane. Network routing is part of SDN that give interest for the research. The most commonly used routing algorithm today is the single path routing algorithm. This algorithm uses only one path as the data transmission medium. This will reduced network performance known as network congestion. In this study we implemented Yen K-Shortest Path as routing algorithm. These algorithm will search for as many K lines as the data transmission medium. The Yen K-shortest path algorithm will minimize network congestion. These algorithms has been implemented using Mininet emulator and Ryu controller in two topology. The tests performed to measure the performance of the algorithm include convergence time, throughput, packet loss. The data obtained in the test using the Yen K-Shortest Path algorithm compared to data obtained using Dijkstra algorithm with the same test method. And there is a test to see the success of the algorithm for using more than one path on multipath testing. In the convergence time test, the Yen K-Shortest Path algorithm gets an average of 0.01962 seconds for the first topology, and 0.02409 seconds for the second topology. Based on the results of throughput testing, the Yen K-Shortest Path algorithm outperformed Dijkstra's algorithm with the highest throughput increase reaching 176.01% larger. For packet loss test results, Yen K-Shortest Path is also superior because it has fewer packet loss than Dijkstra algorithm.

Abstract

The 2013 curriculum is a new curriculum in the Indonesian education system that has been enacted by the government to replace the 2006 curriculum or the Education Unit Level Curriculum. The implementation of this curriculum in recent years has sparked controversy in Indonesian education, students who are demanded more actively, added lessons and other matters that lead to various opinions that develop in the community, especially on Twitter. An estimated 200 million Twitter users post 400 million tweets per day. In this research, sentiment analysis is conducted to find out the developing opinion which is divided into positive opinion or negative opinion. The features and methods used are the ensemble feature and the K-Nearest Neighbor (K-NN) classification method. Ensemble feature is a combined feature, in the form of statistical Bag of Words (BoW) and semantic features (twitter specific, textual features, PoS features, lexicon based features). Based on a series of tests, the combination of features has an impact in improving the accuracy of the K-Nearest Neighbor (K-NN) method for determining positive or negative opinions. Merging this feature can complement the weaknesses of each feature, so the final result of accuracy gained by combining both features reaches 96%. In contrast to using only features independently, the accuracy achieved only reaches 80% on Bag of Words (BoW) features and 82% on ensemble features without Bag of Words (BoW).
