Abstract -
The world has become increasingly interconnected in terms of technology. The use of internet has grown dramatically. Internet plays an important role for the todays business. Every organization wants to secure their moving data because significant data loss can damage the business continuity. So the necessity of network security became obvious. The goal of this paper is to overview the network layer security mechanisms, Internet Protocols Security (IPSec), standard framework and end-to-end architecture .This paper also identifies the services , operation modes of IPSec and discusses the Virtual Private Network (VPN) as an application of IPSec.

Abstract -
The deployment of Wireless Sensor Network (WSN) Nodes in harsh environments with a lack of energy infrastructure brings some challenges to its design. The battery-powered sensor nodes are typically used in the WSN systems. However, the battery has limitations regarding its lifetime; furthermore, certain techniques are required to improve the batterys lifetime. This paper presents two data filtering approaches to improve energy efficiency on the agricultural wireless sensor network. The first approach is the simple moving average (SMA) that performs filtering on a sensor node with more than one sensor device attached. The second one is based on Threshold Sensitive Energy Efficiency Sensor Network (TEEN) protocol for nodes with only one sensor device attached. Evaluation of the results shows that the two proposed approaches are able to improve the energy efficiency of the agricultural wireless sensor network significantly. Moreover, in the SMA, the level of data accuracy is still high. While in the TEEN approach with hard threshold (ht)=0 and soft threshold (st)=1, the duplicate unsent data is still possible to be predicted on the sink side, if the soft threshold value is greater than 1, the sensor nodes should be in the reactive mode and will only send data when the two sensed data differ.

Abstract -
The Hardware Implementation of the physical models offers an outstanding opportunity for engineers in computational computing techniques. Contrary to the software implementation, the physical hardware implementations present the advantage of speed up the computation with inexpensive and practical way. The Finite Difference Method (FDM) is one the most common numerical method used to solve Electromagnetic and Heat transfer problems. In this paper, we present a FPGA-based implementation of the Bio Heat Equation (BHT). We then show the architecture of the proposed model to be implemented in the FPGA platform BEECube. The results of the implementation and simulation are reported and discussed.

Abstract -
Association control is a mechanism that regulates the association between stations and access points in the network. Two mechanisms that can be emulated in Mininet-WiFi as the emulator for SDN in wireless environment are Strongest Signal First (SSF) and Least-loaded First (LLF). In this study, we propose Extended-LLF, which is a refinement of existing mechanism that is able to overcome the weaknesses in LLF. A parameter of maximum RSSI difference is added as a requirement in association decision.Based on the tests conducted on the mobility scenario with 3 access points and 10 stations, Extended LLF mechanism provides better RSSI reception than LLF as the existing load balancing mechanism. In terms of performance, Extended LLF provides an increase over LLF on jitter, packet loss, and throughput by 6.69, 0.38, and 0.04 percent, respectively. However, there is a degradation of performance in terms of delay by 0.85 percent. Compared to SSF, Extended LLF results in better performance in terms of delay, jitter, and throughput by 18.58, 13.46, and 0.05 percent, but with performance degradation of packet loss by 5.86 percent.

Abstract -
The Bali island is located in the central region of Indonesia has a very beautiful sea and diverse. There are many spot diving that can be found on this island of Bali. The underwater life of the fauna is numerous and diverse. Different locations make divers confused in choosing the appropriate location and having difficulty reaching the location. Divers should seek information first to come to the location of the diving. To overcome the above problems required a system design that can help to mapping the points of diving locations on the island of Bali. The information system is built on a mobile basis using the dijkstra algorithm to map the existing diving locations in Bali and look for the nearest route. The diving location mapping system in Bali island by using the dijkstra method is expected to make it easier to find diving locations on the Bali island.

Abstract -
Electronic government (e-government) play an important role in governments that provide services and applications for citizens to support their transactions. Understanding factors that affect user adoption of e-government is of interest to researchers in a diversity of fields. The aim of this study is to explore the important factors affecting the adoption of e-government. This study suggests positive- mixed methods research to explore and predict a causal model and validate the result. This study proposes mixed methods within two phases, qualitative followed by the quantitative. This paper focuses on the qualitative method. In the qualitative phase, interviews and focus groups will be proposed to explore users experiences and beliefs about e-government as well as developing the research framework. Data analysis will be conducted using thematic analysis and coding. This study contributes to the information technology and e-government adoption literature by presenting a novel methodology to explore users beliefs and behaviors toward using e-government services and applications.
