Abstract

IEEE 802.15.5 standard support structure of star and peer-to-peer network formation. Strating from these, the cluster tree network can be built as a special case of peer-to-peer network to increse coverage area. In this paper, we provide an performance evaluation of beacon- enabled mode for IEEE 802.15.4 wireless sensor network on star and cluster topology in order to get the maximum result to apply the appropriate topology model as needed. We conduct analysis on each topology model by using the numbers of nodes from 10 nodes to 100 nodes to analyze throughput, delay, energy consumption, and probability success packet by using NS2 simulator. The simulation results show that the throughput and the probability of success packet of cluster topology are higher than that of star topology, and the energy consumption of cluster topology is lesser than that of star topology. However, cluster topology increases the delay more than star topology.Keywords: IEEE 802.15.4, wireless sensor network, beacon-enabled mode, topology, csma/ca

Abstract

A pricing strategy is adjusting the price of a product based on the quality of the product. Based on this, the pricing strategy used for one product may not be compatible with other products. This pricing strategy then manifests itself in the pricing policy of the company. In this study, the determination of pricing policy implies an examination of the problems with perishable products. This perishable pricing method has to deal with several unique characteristic effects based on perishables. In addition to the price factor,  demand is also determined by the quality of the product being sold. The challenge for retailers is to choose the right price that is comparable to leveraging product-based quality, triggering consumer desire to buy and unleashing demand, ultimately leading to a surge. business profits. In this study, examples of forwarding pricing are developed and then applied to regular, high-low, daily, private, and hybrid pricing policies. Performance based on each of these guidelines is evaluated under the price-conscious consumer category and the quality-conscious consumer category. Mathematical calculations are performed to determine the policy that will provide the most benefit to the price-conscious consumer category and the policy that will provide the most benefit to the quality-conscious consumer category. Price sensitivity and consumer sensitivity tests are performed to determine policy performance and the reality that arises from policy implementation.   Keywords: dynamic pricing, agro, perishables, dynamic, pricing.

Abstract

Pada era modern saat ini, seluruh kehidupan manusia tidak lepas dari penggunaan Teknologi Informasi, terutama pada bidang pemerintahan yang mana menerapkan Sistem Pemerintahan Berbasis Elektronik. Pemerintah Provinsi Jawa Timur merespon perkembangan teknologi dengan mengimplementasikan Sistem Pemerintahan Berbasis Elektronik guna meningkatkan efisiensi kinerja. Namun, penerapan Sistem Pemerintahan Berbasis Elektronik masih memiliki kekurangan, terutama terkait keredundanan data antar instansi pemerintahan. Hal ini menyebabkan ketidakvalidan data dan kemungkinan hasil yang berbeda saat diolah. Dengan bentuk arsitektur Sistem Pemerintahan Berbasis Elektronik yang bersifat taksonomi serta berbentuk terstruktur multi-level yang mengakibatkan tingginya kompleksifitas untuk melakukan diseminasi data khususnya ketika melakukan perhitungan Indikator Kinerja Utama. Melalui permasalahan yang dijelaskan maka peneliti mengembangkan sistem perancangan aplikasi satu data untuk perhitungan Indikator Kinerja Utama pemerintah provinsi Jawa Timur. Sistem yang dikembangkan digunakan untuk memudahkan pengguna dalam mengelola data berdasarkan kategori atau taksonomi. Dengan data yang diinputkan maka stakeholder dapat menentukan sebuah kebijakan berdasarkan data yang tersedia pada aplikasi tersebut secara real time dan diperbarui secara berkala.

Abstract

Cyber threats are complex and diverse issues. Various types of threats emerge daily on the internet. In this research, we proposed a new Cyber Threat Intelligence platform to deal with the challenges above, using Snort as a tool for detecting anonymous network traffic and STIX as a serialization format and standardization of Cyber Threat Intelligence data. As a result, a Cyber Threat Intelligence based on Snort contains Apache Spark as the processing engine, MongoDB as the database, and STIX as the serialization format and data standardization. We test our platform by using two data sources, the CIC-IDS2017 dataset, and the real traffic. We successfully converted the snort alerts to STIX format and visualized them into graph. The graph shows indication of network traffic suspicious, the country of attacker come from, attribute information and attack pattern. The experiment shows that converting Snort data to STIX requires considerable time if the amount of data processed is getting bigger, Real Traffic needs 16 seconds of data preprocessing and 3 minutes of conversion time, while PCAP needs 35 seconds of preprocessing time and 13 minutes of conversion time.
