Dandy Kalma Rahmatullah, S. M. Nasution, Fairuz Azmi
Internet technology today is not free from many problems or security holes. This security holes could be exploited by an unauthorized person to steal important data. The case of the attacks occurred because the party that was attacked also did not realize the importance of network security to be applied to the system. Honeypot is a system that is designed to resemble the original production system and is made with the intention to be attacked or compromised. In this research, Cubieboard implemented using low interaction honeypot as a decoy to attract attackers. The result of this research is a low interaction honeypot implemented on embedded system with the form of Cubieboard that can emulates security vulnerabilities such as directory buster brute force, LFI, and RFI with 100% success rate, but still could not emulates SQL Injection vulnerability. One of the result of stress test with 773 samples, obtained average time of 5275 ms, deviation 2067 ms, sample throughput 367.012 per minute, and with median 5381 ms. The stress test is conducted with 50 threads and 10 ramp-ups per second.
当今的互联网技术并非没有许多问题或安全漏洞。未经授权的人可能会利用这些安全漏洞窃取重要数据。该案件的发生是因为被攻击方也没有意识到网络安全应用于系统的重要性。蜜罐是一种类似于原始生产系统的系统,其目的是被攻击或破坏。在本研究中,Cubieboard采用低交互蜜罐作为诱饵来吸引攻击者。本研究的结果是以Cubieboard的形式在嵌入式系统上实现了一个低交互蜜罐,可以模拟目录破坏器暴力破解、LFI、RFI等安全漏洞,成功率为100%,但仍然无法模拟SQL注入漏洞。其中对773个样本进行压力测试,得到平均时间5275 ms,偏差2067 ms,样本吞吐量367.012 /分钟,中位数5381 ms。压力测试使用50个线程和每秒10个上升进行。

Implementation of PID controller and pre-filter to control non-linear ball and plate system 实现了PID控制器和预滤波器对非线性球板系统的控制
Agung Adiprasetya, Agung Surya Wibowo
In this paper, the authors try to make PID controller with Pre-filter that is implemented at ball and plate system. Ball and plate system will control the position of ball's axis in pixels value by using servo motor as its actuator and webcam as its sensor of position. PID controller with Pre-filter will have a better response than conventional PID controller. Eventhough the response of PID with Pre-filter is slower than conventional PID, the effect of Pre-filter in the system will give the less overshoot response.

Design and implementation of water level control using gain scheduling PID back calculation integrator Anti Windup 基于增益调度PID反计算积分器的水位控制设计与实现
Sony Cahya Pratama, E. Susanto, Agung Surya Wibowo
Conventional PID controller is a simplest known controller and has been used in almost all process industries for controlling process parameter at desired set point. However, the weakness of the controller is largely depend on the parameter of the controlled object. As the dynamics process of a water tank is nonlinear, it also has nonlinear behaviour between the input and output. This paper demonstrates that Gain Scheduling PID with Back Calculation Integrator Antiwindup enables to enhance the response of automatic water level control system performance. A mathematical model of a first order tank system is considered and simulated to determine fine tunes and schedules for the controller parameter based on trial and error experiment so as to adapt with all operating points. The system performance comparison of various setpoint given to the system is performed to prove that the Gain Scheduling PID with Back Calculation Integrator Antiwindup outpaces conventional PID controller.
传统的PID控制器是已知的最简单的控制器,几乎在所有的过程工业中都被用于控制过程参数在所需的设定点上。然而,控制器的缺点很大程度上取决于被控对象的参数。由于水箱的动力学过程是非线性的,因此它在输入和输出之间也具有非线性行为。本文论证了带反计算积分器反卷的增益调度PID能够提高自动水位控制系统的响应性能。考虑并模拟了一阶储罐系统的数学模型,通过试错实验确定了控制器参数的微调和调度,以适应各工况。通过对给定系统各设定值的系统性能比较,证明了带反计算积分器的增益调度PID控制器优于传统PID控制器。

E. Sulaiman, G. M. Romalan, N. H. A. Ghani
Recently, outer-rotor electric machine become a research attention to be applied for in-wheel motor either in electric or hybrid electric vehicles (EVs). Among the competitor for in-wheel machines, the permanent magnet synchronous machine (PMSMs) with an outer-rotor have been used widely due to their high performances in terms of torque ad power. However, there is drawback cause by demagnetization and mechanical damage of the rotor magnets in extreme driving conditions. Therefore, the initial design of improvement the 12S-14P outer-rotor flux switching permanent magnet machine (ORFSPMM) for in-wheel machine is proposed and analyze to solve the problem. Then, the design has been optimized using combination of local and global optimization methods in order to enhance the design to reach the maximum performances. Finally, the torque performance for optimized 12S-14P ORFSPM has been improved 64.4% higher than initial performance.

Zulkhan Hafiidh Kumiawan, L. V. Yovita, T. Wibowo
Delay Tolerant Network (DTN) is a wireless network that connected in an intermittently manner and have dynamic topology. In DTN to design protocol routing is a big challenge due to there is no end-to-end path. To overcome this challenge there is protocol routing dLife. dLife is a protocol routing in DTN that use two utility function to determine forwarding decision, namely TECD (Time-Evolving Contact Duration) and TECD importance. In this paper we study the impact of buffer size and message size on the performance of dLife routing. For the simulation we used Opportunistic Network Environment (ONE) Simulator. The performance that is analyzed are Overhead Ratio, Delivery Probability and Average Latency. Based on simulation result, buffer size and message size affect to the performance of dLife routing.

Robust blind beamforming for LTE in multipath environment 多径环境下LTE的鲁棒盲波束形成
H. Elkamchouchi, O. G. Mohamed, D. Mohamed, W. Ali
A robust blind beamforming algorithm is proposed for Long Term Evolution (LTE) system in the uplink direction using a Uniform Linear Array (ULA) at the base station (eNodeB) in the multipath environment. There is no information about the incoming signals, so a robust estimation of the Direction of Arrival (DOA) of the received signals is performed first. The robust Re-iterative Superresolution (RISR) DOA estimation algorithm is implemented to estimate the DOA and to separate the coherent signals impinging from different directions due to multipath, then a robust RISR beamforming is proposed for each estimated direction, followed by time delay estimation of signals using the correlation function between each two signals to obtain the signal in the desired direction (direct signal). Finally, applying the beamforming in the desired direction to correctly receive the signal and reject the multipath effect as well as enhancing Bit error rate (BER). The results show the effectiveness of the proposed algorithm when compared to other traditional beamforming algorithms especially for coherent sources.
提出了一种基于多径环境下基站均匀线性阵列(ULA)的长期演进(LTE)系统上行方向的鲁棒盲波束形成算法。由于没有关于输入信号的信息,因此首先对接收信号的到达方向(DOA)进行鲁棒估计。首先实现鲁棒再迭代超分辨(RISR) DOA估计算法,对DOA进行估计,并对多径干扰下不同方向的相干信号进行分离,然后对每个估计方向进行鲁棒再迭代超分辨波束形成,然后利用两信号之间的相关函数对信号进行时延估计,得到期望方向的信号(直接信号)。最后,在期望的方向上应用波束形成,以正确接收信号,抑制多径效应,提高误码率。实验结果表明,与其他传统的波束形成算法相比,该算法在相干波束形成中具有较好的效果。
