Abstract

News Feature Scoring (NeFS) merupakan metode pembobotan kalimat yang sering digunakan untuk melakukan pembobotan kalimat pada peringkasan dokumen berdasarkan fitur berita. Beberapa fitur berita diantaranya seperti word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), dan kemiripan kalimat terhadap judul. Metode NeFS mampu memilih kalimat penting dengan menghitung frekuensi kata dan mengukur similaritas kata antara kalimat dengan judul. Akan tetapi pembobotan dengan metode NeFS tidak cukup, karena metode tersebut mengabaikan kata informatif yang terkandung dalam kalimat. Kata-kata informatif yang terkandung pada kalimat dapat mengindikasikan bahwa kalimat tersebut penting. Penelitian ini bertujuan untuk melakukan pembobotan kalimat pada peringkasan multi-dokumen berita dengan pendekatan fitur berita dan informasi gramatikal (NeFGIS). Informasi gramatikal yang dibawa oleh part of speech tagging (POS Tagging) dapat menunjukkan adanya konten informatif. Pembobotan kalimat dengan pendekatan fitur berita dan informasi gramatikal diharapkan mampu memilih kalimat representatif secara lebih baik dan mampu meningkatkan kualitas hasil ringkasan. Pada penelitian ini terdapat 4 tahapan yang dilakukan antara lain seleksi berita, text preprocessing, sentence scoring, dan penyusunan ringkasan. Untuk mengukur hasil ringkasan menggunakan metode evaluasi Recall-Oriented Understudy for Gisting Evaluation (ROUGE) dengan empat varian fungsi yaitu ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4. Hasil ringkasan menggunakan metode yang diusulkan (NeFGIS) dibandingkan dengan hasil ringkasan menggunakan metode pembobotan dengan pendekatan fitur berita dan trending issue (NeFTIS). Metode NeFGIS memberikan hasil yang lebih baik dengan peningkatan nilai untuk fungsi recall pada ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4 secara berturut-turut adalah 20,37%, 33,33%, 1,85%, 23,14%.   News Feature Scoring (NeFS) is a sentence weighting method that used to weight the sentences in document summarization based on news features. There are several news features including word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), and sentences resemblance to the title. The NeFS method is able to select important sentences by calculating the frequency of words and measuring the similarity of words between sentences and titles. However, NeFS weighting method is not enough, because the method ignores the informative word in the sentence. The informative words contained in the sentence can indicate that the sentence is important. This study aims to weight the sentence in news multi-document summarization with news feature and grammatical information approach (NeFGIS). Grammatical information carried by part of speech tagging (POS Tagging) can indicate the presence of informative content. Sentence weighting with news features and grammatical information approach is expected to be able to determine sentence representatives better and be able to improve the quality of the summary results. In this study, there are 4 stages that are carried out including news selection, text preprocessing, sentence scoring, and compilation of summaries. Recall-Oriented Understanding for Gisting Evaluation (ROUGE) is used to measure the summary results with four variants of function; ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4. Summary results using the proposed method (NeFGIS) are compared with summary results using sentence weighting methods with news feature and trending issue approach (NeFTIS). The NeFGIS method provides better results with increased value for recall functions in ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4 respectively 20.37%, 33.33%, 1.85%, 23.14%.

Abstract

Development of a grid-based clustering mechanism to improve LEACH performance in the Wireless Sensor Network environmentLow Energy Adaptive Clustering Hierarchy (LEACH) merupakan algoritma routing pada Wireless Sensor Network (WSN) berbasis cluster. LEACH memilih sebuah node sebagai cluster head (CH) yang tugasnya untuk melakukan komunikasi dengan sink maupun guna mengumpulkan data dari member node. Persebaran CH pada LEACH yang dikatakan acak, kadang mengalami masalah mengingat rumus probabilitas pada tiap round. Hal ini akan menyebabkan CH yang terpilih bisa berada di tepi area, juga terjadinya pemborosan energi karena jalur yang terbentuk akan menjadi panjang. Oleh karena itu, kami ingin mengembangkan routing protocol G-LEACH menggunakan teknik merge CH dalam suatu area (grid) disertai beberapa parameter yang relevan, seperti posisi node, node dengan sisa energi terbesar, dan jarak yang dihitung dalam tiga jarak yaitu jarak node menuju cluster center, jarak node menuju merge CH, dan jarak merge CH menuju sink. Hasil pengujian menunjukan bahwa dengan menggabungkan cluster (merge CH) pada transmisi data menuju sink pada protokol G-LEACH dapat menghasilkan masa hidup jaringan yang lebih lama pada seluruh operasi node, energi yang dibutuhkan pada semua node lebih rendah, dan lebih banyak paket data yang dikirim dan diterima oleh sink. Low Energy Adaptive Clustering Hierarchy (LEACH) is a routing algorithm in a cluster-based Wireless Sensor Network (WSN). LEACH selects a node as a cluster head (CH) whose responsibility is for communicating with sinks and collect data from the node members. The distribution of CH on LEACH, which is basically random, sometimes has a problem in remembering the probability formula on each round. This may make the selected CH on the edge of the area as well as generate energy waste because the pathway formed will be lengthy. Therefore, we would like to develop the G-LEACH routing protocol using a merge CH technique in one area (grid) with several relevant parameters, such as the position of the node, the node with the largest remaining energy, and the distance calculated in three distances: the distance of the node to the clustercenter, the distance of the node to the merge CH, and the distance of the merge CH to the sink. The test result showed that combining clusters (merge CH) in the data transmission to the sink in the G-LEACH protocol could produce a longer network life on all node operations, lower energy required for all nodes, and more data package sent and received by the sink.

Abstract

Authentication is a method for securing an account by verifying the user identity by inputting email with a password. Two factor authentications is an authentication system that combines the first-factor authentication with the second factor. General two factor authentication by entering an email or username with a password are similar. However, two factor authentication requires additional information that must be inputted by the user. Additional information can be in the form of tokens or one-time passwords (OTP). Two factor authentications generally still uses third-party services to generate token or OTP still have vulnerable because can attacked from tokens steal through MITM and found that the generated tokens with the same value. Therefore, we propose a two-factor authentication framework based on ethereum blockchain with dApp as token generation system. Firstly, outcome from the analysis of the system, next succeeded in creating a two-factor authentication system without using third-parties. Second, token system generate up to 3164 different tokens  in one second and has been collisions tested. Third, security method to protect token from MITM attack. The attacker unable to get access caused all the checking are done by dApp user authentication.

Abstract

This research was based on the modification of the DeLone and McLean information systems models by adding end-user computing satisfaction variables to determine the success factors for e-government systems. This model was adopted due to the aim of this study to investigate the factors responsible for the successful implementation of e-government by bringing it closer to public value. However, while the DeLone and McLean models focus more on the information system approach, the model proposed was on the premise that system quality (SQ), information quality (IQ), content (CO) and format (FO) are determinants of e-government system user satisfaction. Furthermore, the net benefits through a five-dimensional public value determinants were used to evaluate e-government websites from a community perspective. Responses from 150 communities were analyzed by smart PLS 3.0 using structural equation models to examine the relationship between the constructs of the proposed model. This study contributes to the research gap in adopting DeLone and McLean's model in the e-government due to the limitation in its validation for different contexts. The results support the effect of content variables on user satisfaction and simultaneously prove that it is possible to explain net benefits, with an r-squared value of 69.1%, using the variables in the proposed model. The five dimensions of public value adopted all proved to have a positive influence with a confidence level of 95%. The level of construct significance identified is able to help in the formulation of strategies to improve e-government services.
