This article discusses a preliminary study of developing a paddlewheel aerator for shrimp ponds using an integrated intelligent aquaculture system to support intensification. Two paddlewheel aerators with different phases have been successfully installed. The test was carried out on two different types of motors, which were intended to comprehend the performance of every motor on a paddlewheel aerator. The ratio of the speed values for a single-phase motor was 102 rpm and for a 3-phase motor was 110.3 rpm. The data from the performance observation of the aeration wheel motor can be viewed via a smartphone using a website application. The data displayed from the observations are in the form of data on voltage, current, frequency, power, power factor, and the power generated by the pinwheel motor. The test results show the performance of the aeration wheel motor that works under normal conditions with an average measurement error of 0.23%, below the acceptable error limit of 0.5%. This research forms the basis for a smart aquaculture system that can be developed domestically to support local industries in Indonesia.

The implementation of knowledge management in a company has become a necessity in the current 4.0 era. Therefore, the company's ability to manage existing knowledge is needed to survive the onslaught of competition. To implement knowledge management in one of the Web Hosting companies towards service to consumers is the aim of this research, as well as a solution to the problems experienced in the Customer Support division. Due to this, the problem-solving process is often hampered and the existing problems are not properly archived. In this study, knowledge of the organization is figured out by analyzing the support of existing information technology. Focus Group Discussion (FGD) method is used as a tool to find out the abilities and skills that exist in each of them, in order to figure out the extent to which a person's perspective is to see and assess something he observes. In this study, Web Hosting Management Complete Solution (WHMCS) is a system used in applying knowledge to web hosting companies for the knowledge-sharing process between customer support and consumers.

The identification model development of the power disturbance signals with the deep convolutional neural networks (CNNs) method involves a large amount of data. However, the real signal data is limited. Therefore, researchers employ synthetic signal data. These signals can be generated by the formula IEEE standardized. In these formulas, two categories have a similar formula i.e interruption and sag. The difference is only in the intensity parameter (α). This paper analyzed the model performance of identifying those disturbances where the intensity values are set differently for training and testing datasets based on the upper bound value α of sag and the lower bound value α of interruption. Several noise levels are included in the signals. So, there are several datasets with noises in this simulation. Furthermore, those datasets are trained using the model based on deep CNN. The test results show that the true positive (TP) of the model's performance in identifying the interruption signal is 93.54% and the sag signal is 78.78%. In addition, the performance of the model using a dataset without noise obtained a high percentage in accuracy, precision, and f1-score parameters with 92.4%, 97.4%, and 92,76%, respectively.
用深度卷积神经网络(CNNs)方法开发电力扰动信号的识别模型涉及大量数据。然而,真实的信号数据是有限的。因此,研究人员采用了合成信号数据。这些信号可以通过IEEE标准化的公式来生成。在这些公式中,有两类具有相似的公式,即中断和凹陷。差异仅在于强度参数(α)。本文基于凹陷的上界值α和中断的下界值α,分析了识别训练和测试数据集中强度值设置不同的扰动的模型性能。信号中包括多个噪声级别。因此,在这个模拟中有几个带有噪声的数据集。此外,使用基于深度CNN的模型对这些数据集进行训练。测试结果表明,该模型在识别中断信号方面的真阳性率(TP)为93.54%,凹陷信号为78.78%。此外,使用无噪声数据集的模型在准确度、精度和f1评分参数方面获得了较高的百分比,分别为92.4%、97.4%和92,76%。

Studies related to manipulators are still being carried out, along with the times and needs. Utilization in manufacturing and fabrication has led to the development of many manipulators. Smooth, fast, and accurate movement continue to be developed. In the case of the multi manipulator, 7 DOF (Degree of Freedom) is a type of manipulator that has special features in terms of joints. Inverse kinematic is a parameter used to control the orientation and movement of the manipulator. 7 DOF has three singularity wrist, elbow, and shoulder. In the simulation, each singularity produces an inverse kinematic matrix which is used to control the movement of the manipulator. The method used is to determine the angle of motion of the joint (continues joint angel) with simulation to produce calculations that are fast, precise, accurate, and stable. The target of each joint with the theta value that has been determined by the singularity was successfully carried out with an error of 0%.

System security issues are a vital factor that needs to be considered in the operation of systems and networks, which will later be used for disaster mitigation and preventing attacks on the network. Distributed Denial of Services (DDoS) is a form of attack carried out by individuals or groups to damage data through servers or malware in the form of flooding packets, therefore it can paralyze the network system used. Network security is a factor that must be maintained and considered in an information system. DDoS can take the form of Ping of Death, flood, Remote control attack, User Data Protocol (UDP) flood, and Smurf Attack. This study aims to develop software to detect DDoS attacks based on network traffic logs. The software has been tested and run according to the neural network algorithm. This software was developed with an interface that makes it easier for users to detect the source IP whether the IP is carrying out a DDoS attack or normal.
系统安全问题是系统和网络运行中需要考虑的一个重要因素,稍后将用于减灾和防止对网络的攻击。分布式拒绝服务(DDoS)是一种由个人或团体通过服务器或恶意软件以淹没数据包的形式破坏数据的攻击形式,因此它可以瘫痪所使用的网络系统。网络安全是信息系统中必须维护和考虑的一个因素。DDoS可以采取Ping of Death、洪水、远程控制攻击、用户数据协议(UDP)洪水和蓝精灵攻击的形式。本研究旨在开发基于网络流量日志的DDoS攻击检测软件。软件已经按照神经网络算法进行了测试和运行。该软件的开发界面使用户更容易检测源IP,无论该IP是否正在进行DDoS攻击。

One of the technological developments in agriculture is smart farming. Shallot farmers still carry out the process of watering shallot plants manually. This takes a long time because farmers have to go around the agricultural land during the watering process. To solve these problems, an automatic shallot sprinkler machine was designed that can be applied by farmers. The Arduino Uno ATMega328 microcontroller is used on this machine as the control system, while Android is used for the interface. The android interface on this machine can provide a graphical display, therefore farmers can give direct orders to drive a DC motor (Direct Current) and a DC pump on/off switch (Direct Current). The results of the smart farming research on this automatic onion sprinkler help farmers get 72% efficient time. The comparison can be seen in the manual watering process on 10,000m2 agricultural land that takes 7 days, on the other hand, it only takes 2 days when it is done with smart farming technology.
农业技术的发展之一是智能农业。种植大葱的农民仍在手工给大葱浇水。这需要很长时间,因为农民在浇水过程中必须绕着农田走一圈。针对这些问题,设计了一种适合农民使用的葱自动洒水机。本机采用Arduino Uno ATMega328微控制器作为控制系统,接口采用Android。该机器上的android界面可以提供图形显示,因此农民可以直接命令驱动直流电机(直流)和直流泵的开/关开关(直流)。智能农业研究的结果表明,这种自动洋葱洒水器可以帮助农民获得72%的有效时间。10000平方米农田的人工浇灌过程需要7天,而智能农业技术只需要2天。

Pengaruh Variasi Media Pendingin Proses Quenching Terhadap Mikrostruktur dan Sifat Mekanik Baja Hadfield 面向Hadfield力学和微观结构的淬火工艺冷却介质变化编辑器

Manganese steel contains 1,2% C and 12% Mn generally recognized as Hadfield steel. Based on the high composition of C and Mn elements, the main structure of this steel is dominated by an austenite matrix that surrounded the carbide phase on the grain boundary.  This structure is usually brittle which leads to improper high-loading conditions. To overcome this problem, the experimental method was carried out by heating Hadfield steel to a temperature of 1000 oC, then followed by a quenching process using cooling media variations namely water and salt bath (20 wt.% NaCl solution). These cooling media variations aim to determine the level of carbide formation which affects the microstructure and mechanical properties. From the test results, it was obtained that Hadfield steel with salt bath (20 wt.% NaCl) quenching variation has significant microstructure transformation which affects enhancement of the value of tensile and yield strength (809,5 and 542,4 MPa), hardness (238 HV), ductility and toughness.
锰钢含有1.2%的C和12%的Mn,通常被认为是哈德菲尔德钢。基于C和Mn元素的高成分,该钢的主要组织由奥氏体基体主导,奥氏体基体围绕晶界上的碳化物相。这种结构通常是脆性的,这导致不适当的高负载条件。为了克服这个问题,实验方法是将哈德菲尔德钢加热到1000℃的温度,然后使用不同的冷却介质,即水和盐浴(20 wt.%NaCl溶液)进行淬火。这些冷却介质的变化旨在确定影响微观结构和机械性能的碳化物形成水平。试验结果表明,经过盐浴(20wt.%NaCl)淬火变化的哈德菲尔德钢具有显著的组织转变,影响了拉伸强度和屈服强度(809,5和542,4MPa)、硬度(238HV)、延展性和韧性的提高。

The lighting system is one of the aspects of assessing the function of the building. The building lighting system is included in the health aspect of the building. To achieve proper function, the building lighting system must meet the illumination value of each room according to the type of utilization in accordance with SNI 6197:2011, SNI 6197:2011, SNI 03-2396-2001, dan SNI 03-6575-2001. This study aims to analyze the lighting system in the Gedung Kuliah Bersama at the Politeknik Negeri Cilacap. This study uses a quantitative method by comparing the amount of light intensity based on field measurements, calculation results, and the SNI 6197:2011 standard. Based on the results of observations, data processing, and measurements, it was found that there were still some rooms in the Gedung Kuliah Bersama that did not meet SNI. Rooms that have fulfilled SNI include classrooms, library rooms, language laboratories, lecturer transit rooms, multipurpose rooms, terrace, and warehouses. It is necessary to carry out maintenance and repair of lamps for rooms that do not meet SNI. Maintenance and repair of lighting systems are carried out by replacing, adding, and/or repositioning lamps.
照明系统是评价建筑功能的一个方面。建筑照明系统包括在建筑的健康方面。建筑照明系统要达到应有的功能,必须根据使用类型满足SNI 6197:2011、SNI 6197:2011、SNI 03-2396-2001、SNI 03-6575-2001规定的各房间照度值。本研究旨在分析位于Politeknik Negeri Cilacap的Gedung Kuliah Bersama的照明系统。本研究采用定量方法,根据现场测量、计算结果和SNI 6197:2011标准对光强量进行比较。根据观察、数据处理和测量的结果,发现Gedung Kuliah Bersama仍有一些房间不符合SNI要求。满足SNI要求的房间包括教室、图书馆、语言实验室、讲师中转室、多功能厅、露台和仓库。对于不符合SNI要求的房间,需要对灯具进行维护和维修。照明系统的维护和维修是通过更换、增加和/或重新定位灯具来进行的。

This study uses a quantitative method by comparing the amount of light intensity based on field measurements, calculation results, and the SNI 6197:2011 standard. Based on the results of observations, data processing, and measurements, it was found that there were still some rooms in the Gedung Kuliah Bersama that did not meet SNI. Rooms that have fulfilled SNI include classrooms, library rooms, language laboratories, lecturer transit rooms, multipurpose rooms, terrace, and warehouses. It is necessary to carry out maintenance and repair of lamps for rooms that do not meet SNI. Maintenance and repair of lighting systems are carried out by replacing, adding, and/or repositioning lamps.","PeriodicalId":33598,"journal":{"name":"Infotekmesin Media Komunikasi Ilmiah Politeknik Cilacap","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41553324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Game is a part of the entertainment that is made as attractive as possible and can be played using electronic media. The development of games in Indonesia has given rise to a new genre in the form of Role Playing games (RPG) which is currently very popular with children, where players play the role of characters in fictional settings. Currently, there are many games that are played by children, but not many provide knowledge about the hero characters of Indonesian puppet characters. This study aims to develop a mobile-based game about wayang characters, especially Arjuna characters who can train children's ability to solve problems, train creativity and form an unyielding optimistic attitude when completing all levels of The Legend Of Archer Game. This game development method uses stages starting from problem identification, data collection, data analysis, system design, system creation, implementation, and testing.
游戏是娱乐的一部分,它尽可能具有吸引力,可以使用电子媒体来玩。印度尼西亚游戏的发展已经产生了一种新的类型,即角色扮演游戏(RPG),目前在儿童中非常受欢迎,玩家在虚构的环境中扮演角色。目前,孩子们玩的游戏很多,但提供印尼木偶英雄人物知识的游戏并不多。本研究旨在开发一款关于大阳角色,尤其是阿诸那角色的手游,在完成《弓箭手传说》的各个关卡的过程中,培养孩子解决问题的能力,培养创造力,形成不屈的乐观态度。这种游戏开发方法使用了从问题识别、数据收集、数据分析、系统设计、系统创建、执行和测试开始的阶段。

Air pollution is increasing due to the high exhaust emissions of motorized vehicles using fossil fuels. The solution is the use of alternative energy. Butanol and Diethyl Ether (DEE) are alcohols that can be used as a fuel mixture and are environmentally friendly. This is because butanol and DEE have high oxygen levels so the oxidation process in the combustion chamber increases and the residual gas results from combustion is better. This study tested the residual gas from the combustion of a 160 cc gasoline engine using a mixture of pertalite-butanol and pertalite-DEE fuels with 5%, 10%, and 15% alcohol percentages. The test results show that adding DEE produces better engine exhaust emissions than adding butanol. CO emissions decreased by 87% using DEE15 while B15 reduced CO by 72%. DEE10 improves HC by 73% while B15 improves HC by 72%. However, DEE15 increases CO2 by 17% and B15 by 11%. Meanwhile, the oxygen content increased by 8% in DEE15 and 6% in B15 compared to pure pertalite.
由于使用化石燃料的机动车辆的高废气排放,空气污染正在增加。解决办法是使用替代能源。丁醇和二乙醚(DEE)是一种可以用作燃料混合物的醇类,对环境友好。这是因为丁醇和DEE具有高氧气水平,因此燃烧室中的氧化过程增加,燃烧产生的残余气体更好。这项研究测试了160 cc汽油发动机燃烧产生的残余气体,该发动机使用了具有5%、10%和15%酒精百分比的pertalite丁醇和pertalite DEE燃料的混合物。试验结果表明,添加避蚊胺比添加丁醇能产生更好的发动机尾气排放。使用DEE15可减少87%的CO排放,而B15可减少72%的CO排放。DEE10可提高73%的HC,而B15可提高72%的HC。然而,DEE15使CO2增加17%,使B15增加11%。同时,与纯方钠石相比,DEE15和B15中的氧含量分别增加了8%和6%。
