Currently, café owners only conduct surveys and then choose locations that they think are appropriate based on several criteria so that café owners are often hesitant in determining the right location. Choosing an improper business location can cause bankruptcy or failure to run a business. This study aims to find out how the AHP method is able to provide problem solving solutions in the selection of locations in the expansion of the café business.

Sentences that can be written indirectly both a little or a lot, will affect other potential customers. So as a result of these comments cause a product sold at an online store has a rating of two things namely "recommended" or "non-recommended". However, detection of positive and negative opinions manually will require more time because of the large amount of data. For this reason opinion mining using technology in data mining can be used to automate positive and negative detection of comments. However, one of the main problems in opinion mining is limited data but has a large number of attributes. In this study, we propose the application of Pearson correlation (PC) based feature selection for opinion mining optimization. The results of the experiment show that the application of PC increases the performance of opinion mining systems in 3 types of classification, namely Logistic Regression, Naïve Bayes and Support Vector Machine, resulting in more optimal accuracy, namely 98.80%, 87.87% and 98.12%.</p> 2019-12-11T17:02:46+07:00 Copyright (c) 2019 Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi) Analisis Risiko dan Kontrol Perlindungan Data Pribadi pada Sistem Informasi Administrasi Kependudukan 2019-12-11T16:40:53+07:00 Iqbal Santosa Raras Yusvinindya <p><em>Sistem Informasi Administrasi Kependudukan (SIAK) is an application used in managing personal data of residents in all cities/districts in Indonesia.

Risk analysis and control of personal data protection on SIAK applications are needed so that the personal data management can be carried out properly and comply with regulatory requirements. Data collected for this study are primary data, sourced from direct observations on the application, interview about assets related to SIAK along with possible risks, and also internal organizations documents. Data analysis was performed with a risk analysis using the ISO 31000: 2018 risk management process approach, where the identification of relevant risks refers to the Generic Risk Scenarios COBIT 5 For Risk, and the determination of relevant controls refers to the Department of Defense Instruction 8500.2 and NIST 800-53. This research involves the Head of Department and employees of Disdukcapil XYZ City that are related to the strategic and operational aspects of SIAK. The results of this study are the identification of 23 possible risks that are spread over 5 processes of personal data protection that classified into the medium-high risk level, and proposed risk control consisting of 19 preventive controls, 6 detective controls, and 2 corrective control. </em></p> 2019-12-11T16:40:52+07:00 Copyright (c) 2019 Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi) Metode McCall’s untuk Pengujian Kualitas Sistem Informasi Administrasi Tugas Akhir (SIATA) 2019-12-12T11:47:57+07:00 Christina Juliane Rizal Dzulkarnaen Windi Susanti <p><em>Department of English, Politeknik Negeri Bandung applies the Information System of Final Project Administration to aid the final assignment administration management.
