Abstract

Wireless communications has been accepted by many organizations and users asit allows to be flexible and portable with increased productivity and lowerinstallation costs. It can be moulded and designed to address different usage anduser needs. WLAN able devices allow users to move their wireless devices fromplace to place within the office without the need of wires and without losing networkconnectivity. It is a well known fact that the wireless networks are vulnerable tomany attacks. Some of the attacks may include interception of sensitive informationthat is not encrypted and transmitted between two wireless devices. Ad hoctransmissions within the network can even compromise the security of a network.Intruders can interfere from inside or out of the network in order to gain connectivityto network management controls and thereby disrupting network resources. Inmost cases the attackers cannot be traced or the purpose of the attack is notknown. Even though we have access to the AP's log files, it has very lessinformation stored in it. Most of the AP's do not provide syslog facilities so that thelogs can be stored at some other server. With the increase in the number of attacktools, security of wireless technologies has become a primary concern. This paperis all about building a device that would be able to watch all the WLAN data andanalysing all the traffic coming and going out of the wireless AP.Keywords: Wireless local area network (WLAN), Access Point (AP), Forensic, WiFiTools,WEP, WPA, 802.11INTRODUCTION

Abstract

Kemiskinan di Indonesia merupakan masalah yang kompleks dan multidimensi, karena tingkat kemiskinan di suatu negara akan mempengaruhi indikator keberhasilan baik dari segi pembangunan maupun perekonomian negara tersebut. Berdasarkan permasalahan tersebut diperlukan sebuah prediksi untuk mengetahui tingkat kemiskinan di Indonesia baik wilayah Perkotaan, Pedesaan maupun secara Nasional. Pada penelitian kali ini, peneliti menggunakan sebuah model dari Box Jenkins yaitu Auto Regresive Moving Average (ARIMA) untuk memprediksi tingkat kemiskinan di Indonesia pada masa yang akan datang. Dataset kemiskinan yang digunakan bersumber dari Badan Pusat Statistik (BPS) dengan data pengujian dari tahun 2011 hingga tahun 2020. Peneliti akan menggunakan 3 parameter error untuk mengevaluasi hasil tingkat kemiskinan di Perkotaan, Pedesaan maupun secara Nasional yaitu RMSE, MAE dan MAPE. Berdasarkan pengujian yang dilakukan bahwa dataset perkotaan menghasilkan model ARIMA(2,2,5) sebagai model ARIMA terbaik dengan RMSE=1.246582, MAE=0.923255 dan MAPE=12%, untuk dataset pedesaan menghasilkan model ARIMA(1,2,1) sebagai yang terbaik dengan RMSE=0.392650, MAE=0.311529 dan MAPE=2%. Sedangkan untuk dataset secara nasional menghasilkan model ARIMA(0,2,5) sebagai yang terbaik dengan RMSE=2.533166, MAE=2.090505 dan MAPE=20%. Dari 3 pengujian tersebut disimpulkan bahwa model ARIMA berhasil memprediksi tingkat kemiskinan di Indonesia baik wilayah Perkotaan, Pedesaan maupun secara Nasional dengan hasil baik.

Abstract

This study aims to analyze how the use and utilization of the Kipin School application supports the learning process at Madrasah Ibtidaiyah Tarbiyatul Islamiyah. This application provides various educational features that can help students and teachers improve the quality of learning, as well as support access to more interactive and easily accessible teaching materials. In this study, the theory used is the theory of technological determination, which emphasizes that technological developments have a dominant influence in shaping social change, including in the world of education. This study uses a qualitative method with a descriptive approach. The paradigm used in this study is the constructivist paradigm. Data collection techniques include in-depth interviews, observations, documentation, and literature studies. The results of the study indicate that the use and utilization of the Kipin School application plays an important role in supporting the learning process at Madrasah Ibtidaiyah Tarbiyatul Islamiyah. This application helps improve access to teaching materials, enriches learning methods, and encourages more active interaction between teachers and students in teaching and learning activities.

Abstract

This research aims to examine whether the publication of financial statements in XBRL format could reduce the level of information asymmetry, measured by the bid-ask spread, in Indonesia’s capital market over eight years of its implementation. Furthermore, this research examines differences in the level of information asymmetry in two observation periods, which are the early stage and the advanced stage of the XBRL implementation. The population in this study are listed companies on the IDX80 index which were sampled using the purposive method. The analytical instrument used is a panel data regression test using a random effect model and the non-parametric Wilcoxon test of statistical differences. Consistent with similar studies, the results show that the publication of financial reports in XBRL format could reduce the level of information asymmetry by providing accurate, integrated, and universally accessible reporting. The difference test further reveals that the level of information asymmetry is lower in the advanced stages compared to the early stages. This suggest that XBRL implementation becomes more effective over time due to the positive developments in institutional readiness and stakeholder facilitation.

Abstract

The bottled water industry applies different water treatment technologies, with some industries using technologies that are less appropriate when considering the type of raw water to be processed. Effective water treatment is the key to success in the bottled water industry, as product quality and business processes heavily depend on the selected water treatment technology. This study aims to evaluate and select the optimal water treatment technology for the bottled water industry using the Vise Kriterijumska Optimizacija Kompromisno Resenje (VIKOR) method, along with economic evaluation through metrics such as IRR, NPV, and PBP. This method considers various relevant criteria, such as product quality, efficiency, costs, environmental impact, and customer satisfaction. The research process begins with data collection from several water treatment technologies used in the bottled water industry in the Pandaan District, Pasuruan Regency, East Java Province. The VIKOR method is then applied to analyze and compare these technologies, along with economic evaluation using metrics such as IRR, NPV, and PBP. The results of the study indicate that the technology used by Company F ranked highest with the lowest compromise value (Q). The findings of this study are expected to provide insights for the bottled water industry in selecting the appropriate water treatment technology, as well as contribute to research in the field of water treatment. Recommendations for the implementation of the selected technology are also presented to improve efficiency and product quality.
