Information system is an asset for a company when the information system is managed properly. In the past, newspapers have become one of the main sources for people who want to get the latest news about what is happening around them. But now, the important role of newspapers is gradually being replaced by online-based news portals that can deliver news very quickly. PT Info Pena Indonesia itself utilizes an information technology in carrying out the process of managing and disseminating the news they produce with the help of a web portal called Jitunews. This research is quantitative in nature, namely explaining the use of survey methods by distributing questionnaires to users of the Jitunews news portal site for data about the characteristics of the ISO/IEC 25010 and McCall methods. The results of the research conducted on the backend and frontend pages show that the Jitunews website deserves a "Good" interpretation value. However, the security and functional suitability variables contained on the frontend page have the lowest values of all the variables studied, namely 74.43% and 77.50% with the interpretation of "Enough". This can be input for stakeholders to improve the quality of the website in order to increase user satisfaction with the Jitunews news website portal.
Abstract-Agriculture is the backbone to the living being that plays a vital role to country's economy. Agriculture production is inversely affected by pest infestation and plant diseases. Plants vitality is directly affected by the pests as poor or abnormal. Automatic pest detection and classification is an essential research phenomenon, as early detection and classification of pests as they appear on the plants may lead to minimizing the loss of production. This study puts forth a comprehensive model that would facilitate the detection and classification of the pests by using Artificial Neural Network (ANN). In this approach, the image has been segmented from the fields by using enhanced K-Mean segmentation technique that identifies the pests or any object from the image. Subsequently, features will be extracted by using Discrete Cosine Transform (DCT) and classified using ANN to classify pests. The proposed approach is verified for five pests that exhibited 94% effectiveness while classifying the pests.
Saham adalah sebuah bukti kepemilikan nilai sebuah perusahaan, artinya pemilik saham adalah pemilik perusahaan . Semakin besar saham yang dimiliki, maka semakin besar kekuasaannya di perusahaan tersebut. Faktor yang terjadi sekarang dalam sektor pasar saham yaitu adanya dampak dari virus corona terhadap indeks harga saham dan arus dana asing ke pasar saham. Maka sangat perlu untuk dilakukan prediksi sentiment analysis pandemi corona terhadap sektor pasar saham untuk melihat bagaimana perbandingan pergerakan IHSG di Indonesia sebelum terjadi pandemi dan pada saat terjadi pandemi Covid-19. Metode yang digunakan untuk prediksi analysis sentimen dengan index harga saham Indonesia ini menggunakan transformers dengan fitur bag of word , TF-IDF dan word embedding. Dari hasil prediksi sebelum menggunakan metode transformers pada LSTM,dan GRU didapatkan rata-rata pada LSTM Performance akurasi 0,394 dan GRU 0,216 [1]. Algoritma yang yang digunakan dalam model ini adalah Long short-term memory (LSTM), dan Gated Recurrent Unit (GRU), sedangkan untuk mendapatkan hasil word embedding menggunakan Vector space model. Terdapat 1989 baris data dan 27 atribut, sedangkan untuk akurasi yang dihasilkan setelah melakukan iterasi beberapa kali mendapatkan hasil yang signifikan, performance yang dihasilkan adalah semakin mendekati akurasi yang cukup tinggi. Berdasarkan hasil eksprimen perbandingan performance akurasi antara LSTM dan GRU terhadap penggunaan Transformers, maka terlihat lebih baik performance akurasinya setelah menggunakan transformers pada ketiga model tersebut.
This research introduces four different tools designed for fault type classifications at distribution network. The proposed designs are using Artificial Neural Network, Fuzzy Logic, conventional method and Support Vector Machine as the research techniques with input data obtained from PSCAD simulation. The circuit configuration for fault disturbance at the distribution network was simulated by PSCAD simulation program. The research techniques were applied with multiples input values of voltage and current that extracted from the PSCAD simulation. This research testifies the output result by using different fault resistance values; 0.01Ω, 10Ω, 30Ω, 50Ω and 70Ω. Voltage sag and current swell of phase a, b and c that were obtained from the PSCAD simulation have been used as the input variables for the four different research tools design. The acquired results that represented in average accuracy (%) shows that voltage sag and current swell can draw a satisfying accuracy in classifying the fault type.
Food Assistance Program (Program Sembako) is a development of the Non-Cash Food Assistance (BPNT) program which has been implemented by the Ministry of Social Affairs since 2017, namely of food assistance in the form of non-cash from the government which is given to Beneficiary Families (KPM) every month through an electronic account mechanism that is used only to buy food in food traders/e-warong in collaboration with banks. Twitter social media has now become one of the places to disseminate information about the Program Sembako/BPNT. This case study uses text mining techniques with the support vector machine (SVM), Naïve Bayes (NB) and K-Nearest Neighbor (k-NN) methods which aims to classify public sentiment towards the Program Sembako/BPNT on Twitter. The dataset used is tweets in Indonesian with the keywords “BPNT” and “Kartu Sembako” with a total dataset of 1,094 tweets. Text mining, transformation, tokenize, stemming and classification, etc. A useful technique for constructing sentiment classification and analysis. RapidMiner and Gataframework are also used to help create sentiment analysis to measure classification values. The results obtained by optimization using Particle Swam Optimization (PSO) using the support vector machine (SVM) algorithm and the accuracy value obtained is 78.02%, with a precision value of 78.73%, a recall value of 82.16%, and an AUC of 0.848
