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.

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.

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.

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.

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.
