In a country’s economy, small and medium-sized enterprises (SMEs) play an important role. In Indonesia, SMEs are the largest business group and are able to survive in conditions of economic crisis. Utilization of e-business applications by SMEs can be widely used, including to increase product sales, organizational collaboration, and support the organization's business processes. By using e-business applications, companies are able to benefit from several advantages, including positive results for organizational efficiency through promoting higher gross margins, profitability, financial management and operational excellence for employees. However, SMEs have a wide variety of characteristics. Several studies identify SMEs according to their scale. Other studies reveal that SMEs can be grouped based on the nature of the organization in using e-business applications. Thus, the proposed e-business application for SMEs is not a single-size solution, but rather needs to consider the profile of the organization. In this study, a method for recommending e¬business applications for SMEs was proposed based on the organizational profile. The proposed method uses Kano Classification to determine E-Business application preferences, as a basis for e-business application requirements. Meanwhile for training data and prediction, Random Forest Classification is used. Based on the Classification Report, the precision results was 0.87, the recall was 0.46, and the f-1 score was 0.55. In the case study carried out, the proposed method can produce appropriate e-business application recommendations based on the readiness profile of the organization.
在一个国家的经济中,中小企业扮演着重要的角色。在印尼,中小企业是最大的商业群体,能够在经济危机的条件下生存。中小企业可以广泛使用电子商务应用程序,包括增加产品销售、组织协作和支持组织的业务流程。通过使用电子商务应用程序,公司能够受益于几个优势,包括通过提高毛利率、盈利能力、财务管理和员工的卓越运营来提高组织效率的积极结果。然而,中小企业具有多种特点。有几项研究根据规模来确定中小企业。其他研究表明,中小企业可以根据使用电子商务应用程序的组织性质进行分组。因此,建议的中小企业电子商务应用程序不是单一规模的解决方案,而是需要考虑组织的概况。在本研究中,提出了一种基于组织概况的中小企业电子商务应用推荐方法。所建议的方法使用Kano分类来确定电子商务应用程序首选项,作为电子商务应用程序需求的基础。同时,对于训练数据和预测,采用随机森林分类。基于分类报告,精密度为0.87,召回率为0.46,f-1得分为0.55。在执行的案例研究中,所建议的方法可以根据组织的准备情况概要生成适当的电子商务应用程序建议。

Interference Management in Heterogeneous Networks using Modified Mothflame Optimization 基于改进Mothflame优化的异构网络干扰管理
Fajar Setiawan, I. Wayan Mustika, Khampaserth Xaphakdy, D. D. Ariananda
Resource block management for network optimization is necessary in order to minimize interference, thus improving network performance. In a heterogeneous network where the femtocells are deployed inside a macrocell, the co-tier and cross-tier interference are still an issue in this research area. This interference can lead to degradation of the system performance. A proper resource block management is then required to reduce the interference. Several studies to reduce the interference have been conducted using various optimization methods, such as discrete bacterial foraging optimization (DBFO) and random scheme. However, interference reduction using a modified discrete mothflame optimization algorithm (DMFO) method has never been carried out before. Thus, a DMFO algorithm, which is one of nature-inspired algorithms, has been proposed to solve the resource block allocation problem. A heterogeneous system model combined with the DMFO algorithm has shown some significant acceleration. Compared to the DBFO and random scheme, DMFO was found to yield a better performance as proven by cumulative distribution function (CDF) of signal to interference noise ratio (SINR) graphic.
为了减少干扰,提高网络性能,需要对网络进行资源块管理。在异构网络中,飞基站部署在宏基站内,协同层和跨层干扰仍然是该研究领域的一个问题。这种干扰会导致系统性能的下降。然后需要适当的资源块管理来减少干扰。利用离散细菌觅食优化(DBFO)和随机优化(random scheme)等多种优化方法进行了减少干扰的研究。然而,利用改进的离散母焰优化算法(DMFO)方法进行干扰抑制的研究从未有过。因此,本文提出了一种基于自然启发的DMFO算法来解决资源块分配问题。结合DMFO算法的异构系统模型显示出明显的加速效果。信噪比(SINR)图的累积分布函数(CDF)证明了DMFO方案比DBFO方案和随机方案具有更好的性能。

Long Range (LORA) is a device capable of communicating remotely with LPWAN topologies. LPWAN cannot do multi-hop so this research needed to be done. There are several multi-hop supporting algorithms such as Media Access Control (MAC) and routing table. This paper discusses a simple routing table algorithm and messages delivered with the requirement that the next node is bigger or smaller than what is sent. Node tables and proposed method in single multi-hop produced 99% PDR.

Design and Kinematic Analysis of Quadrupedal Cat-Like Robot 四足仿猫机器人的设计与运动学分析
M. Ariyanto, M. Munadi, J. Setiawan, Setyo Wisnu Wardana
Robotics technology is one of the most important technologies in determining the progress of civilization in the world. Since the invention of mobile robot technology, the development of robotics has occurred in almost every sector of life, such as the military, manufacturing, industry, health, and others. On a mobile robot, there are two classifications of mechanisms used, namely the legged mechanism and the wheel mechanism. Of the two mechanisms, legged robots have advantages over wheel robots, because leg robots can pass through all the terrains to be traversed. In the legged robots, quadruped robots are easier to manufacture and control than a two-legged (biped) robot, and a six-legged robot (hexapod). Therefore, this study seeks to develop a Quadrupedal Robot inspired by the structure and movement of a cat. In this first phase of research, the robot was manufactured with a total weight of 1293 g and dimensions of 43 cm long, 20.5 cm wide, and 22 cm high. The equation of motion uses the geometry equation to model and determine the position of the end-effector (leg-tip) and perform a kinematic simulation with the toolbox in Matlab. The result of 2D forward kinematics is highly nonlinear that it is difficult to solve by analytical solutions. Symbolic toolbox and ‘solve’ command under Matlab software is utilized to obtain the joint angle inputs. The acquired angles are then used as input on the Simulink block to be embedded on the microcontroller, and the actuator on the robot, before the prototype is carried out in a straight walking test. From the results of walk test, the robot can successfully walk without falling. The robot can walk without orientation feedback control.
机器人技术是决定世界文明进步的最重要的技术之一。自从移动机器人技术发明以来,机器人技术的发展几乎发生在生活的各个领域,如军事、制造、工业、卫生等。在移动机器人上,有两种类型的机构,即腿式机构和轮式机构。在这两种机构中,腿式机器人比轮式机器人有优势,因为腿式机器人可以通过所有要穿越的地形。在有腿机器人中,四足机器人比两足机器人和六足机器人更容易制造和控制。因此,本研究旨在开发一种受猫的结构和运动启发的四足机器人。在第一阶段的研究中,机器人的总重量为1293克,尺寸为43厘米长,20.5厘米宽,22厘米高。运动方程采用几何方程对末端执行器(腿尖)的位置进行建模和确定,并利用Matlab中的工具箱进行运动学仿真。二维正运动学的结果是高度非线性的,难以用解析解求解。利用Matlab软件下的符号工具箱和“solve”命令获取关节角度输入。然后,在原型进行直线行走测试之前,将获取的角度用作Simulink模块的输入,该模块将嵌入微控制器和机器人上的执行器。从行走测试的结果来看,机器人可以成功地行走而不摔倒。该机器人无需方向反馈控制即可行走。

Analysis of Artificial Dielectric Material Effect on The Performance of Microstrip Antennas 人造介电材料对微带天线性能的影响分析
Barokatun Hasanah, Purwa Aditya Wisnu W., Mifta Nur Farid
In this paper artificial dielectric material is used to make microstrip antennas with a resonance frequency of 2.4 GHz. Artificial dielectric materials are produced by the modification of natural dielectrics present in conventional antennas. Modifications were made in 3 ways and antenna parameter changes were observed. The first modification is to vary the thickness of the substrate from 1.6 mm to 11.2 mm. At a thickness of 6.4 m, the results are obtained quite well so that it can be used as a reference for further simulation. The second modification is by inserting a cylindrical conductor on the substrate, with a variation of the cylinder conductor being inserted from 4 to 12. The results obtained are 4 conductors that produce the best parameters of the antenna, including resonant frequency, amplification, VSWR, radiation pattern and S11. The last modification is to vary the diameter of the inserted conductor from 1 mm to 1.5 mm. As with previous simulations, any change in the conductor diameter is observed for the parameters of the antenna. Results from the 1.2 mm diameter conductor are 2.4 GHz resonance frequency, 7.67 dB gain, -46.13 dB S11, 1.03 VSWR and 125 MHz bandwidth. The results of this study show that all material changes made affect all parameters of the antenna, such as decreasing frequency, larger or smaller bandwidth, changes in the direction of the pattern of radiation, VSWR values, and also S11.
本文采用人工介质材料制作谐振频率为2.4 GHz的微带天线。人造介电材料是通过对传统天线中的天然介电物质进行改性而产生的。通过3种方式进行修改,观察天线参数的变化。第一个修改是改变基材的厚度从1.6毫米到11.2毫米。在厚度为6.4 m时,得到了较好的结果,为进一步的模拟提供了参考。第二种修改是通过在基板上插入圆柱形导体,圆柱形导体的变化从4插入到12。结果表明,谐振频率、放大倍数、驻波比、辐射方向图和S11等4种导体能产生最佳的天线参数。最后的修改是改变插入导体的直径从1mm到1.5 mm。与先前的模拟一样,观察到天线参数的导体直径的任何变化。1.2 mm直径导体的谐振频率为2.4 GHz,增益为7.67 dB, S11为-46.13 dB, VSWR为1.03,带宽为125 MHz。研究结果表明,材料的变化会影响天线的所有参数,如频率的降低、带宽的增大或减小、辐射方向图的变化、驻波比值的变化以及S11。

KP Hiu Macan, KP Takalongan, KP Padaido, KP Todak, KP Baracuda, KP Paus, KP Akar Bahar
The Indonesian Fisheries Management Area (FMA) consists of eleven regions, one of which is FMA-713. FMA-713 includes Makassar Strait Waters, Bone Bay, Flores Sea and Bali Sea with an area of 203,920 Mil2. Problems that often occur in FMA-713 include high illegal fishing, overfishing, fishing with bombs. The influencing factor is the lack of Fishery Surveillance Vessel owned by the Ministry of Maritime Affairs and Fisheries which are assigned to FMA-713. The purpose of this research is to choose the optimal number of fishery surveillance vessel to operate in FMA-713. To solve this problem, the method used is the Genetic Algorithm method. Genetic Algorithm is the most widely used optimization method to solve multi-objective problems. The results of the optimization recommend the number of ships operating in FMA-713 are six ships of type A-B-B-B-C-C with an achievement area coverage of 209,342 Mil2 and operational costs of IDR. 1,621,184,100. The findings in this study can be used as a consideration by the Government to determine policies to improve Indonesia's marine security.

Hartatik, Hanif Al Fatta, Utsman Fajar
Internet access in Indonesia brings both negative and positive impact. The data shows that there is a significant raise the number of children who access porn image. The researcher tried to implement the Convolutional Neural Network (CNN) algorithm and Long-Short Term Memory (LSTM) algorithm using learning transfer to predict the caption of a pornographic image. The input space given is a pornographic image that would be extracted using the bottleneck layer of CNN encoder. The weight values in the extraction were obtained from the pre-trained model using Inception V3. Image captioning was processed using one hot encoding technique and produced one hot vector. The results of feature extraction by bottleneck layer and one hot vector are used as training datasets by the LSTM network. The accuracy of the model was calculated using BLEU, METEOR and CIDEr matrices with a score range of 0 to 100. The results of BLEU-1 to BLEU-4 shows the score of 55.84; 24.01; 10.57; 4.59 respectively, METEOR at 12.75 and CIDEr at 43.84.
印度尼西亚的互联网接入带来了消极和积极的影响。数据显示,接触色情图片的儿童人数显著增加。研究人员试图利用学习迁移实现卷积神经网络(CNN)算法和长短期记忆(LSTM)算法来预测色情图片的标题。给定的输入空间是一张色情图片,将使用CNN编码器的瓶颈层进行提取。提取中的权重值是使用Inception V3从预训练的模型中获得的。采用一种热编码技术对图像字幕进行处理,生成一个热向量。瓶颈层特征提取的结果和一个热向量作为LSTM网络的训练数据集。使用BLEU、METEOR和CIDEr矩阵计算模型的精度,得分范围为0到100。BLEU-1至BLEU-4成绩为55.84分;24.01;10.57;METEOR为12.75,CIDEr为43.84。

Improved internet wireless reverse charging models under multi link service network by end-to-end delay QoS attribute 利用端到端时延QoS属性改进了多链路业务网络下的互联网无线反向收费模型
F. Puspita, Weny Herlina, Septia Anggraini, Bella Arisha, Y. Yunita
This paper attempts to design the model of Improved Internet Reverse Charging (IRC) which is seldom discussed in some literature. This model is intended to work in multilink wireless internet in multi service Quality of Service (QoS) network that works in some traffics. IRC basically is focused on 3G and 4G turnover while doing the hosting. The models designed are formed in finding the optimal solution of pricing the internet. The mathematical formulation was modelled as Mixed Integer Nonlinear Programming problem (MINLP). IRC based modeling in the consumption of end-to- end delay Quality of Service (QoS) attributes was discussed to obtain the optimal solution. Optimal pricing scheme applied to local data server, using digilib traffic data. Improved IRC models were solved using LINGO 13.0. Basically, the internet network is not in the form of a single link only, but there is also a multilink, it is necessary to develop multilink internet network to match the reality. The results show, by setting up basic price to be varied ISP (Internet Service Provider) has choice to have competition in market and quality premium to be fixed or varied, then ISP choices to customer to select class/service and promote certain service, respectively.
本文试图设计一些文献中很少讨论的改进型互联网反向收费(IRC)模型。该模型适用于多链路无线互联网中的多业务QoS (Quality of service)网络。IRC在做托管时主要关注3G和4G的营业额。所设计的模型是在寻找互联网定价的最优解的过程中形成的。将其数学模型化为混合整数非线性规划问题(MINLP)。讨论了基于IRC的端到端时延服务质量(QoS)属性消耗建模,得到了最优解。将最优定价方案应用于本地数据服务器,使用数字流量数据。改进的IRC模型使用LINGO 13.0求解。从根本上说,互联网并不仅仅是以单链路的形式存在,还存在着多链路,因此发展多链路的互联网是符合现实的。结果表明,通过设置不同的基本价格,ISP (Internet Service Provider)可以选择在市场上进行竞争,而质量溢价是固定的或可变的,然后ISP的选择分别给客户选择类别/服务和推广某种服务。
