<![CDATA[Every computer needs and must have an IP Address to connect with other computer network users, the IP Address will be automatically distributed to network users using the Router as a DHCP Server. In addition to DHCP, the Router has a DHCP Accounting service that can improve network security with AAA and RADIUS Server features that can be implemented with Freeradius. DHCP Accounting has accounting capabilities for secure START and STOP message transmission, but the flash memory capacity on the C2691 router is around 32 MB, making the DHCP Accounting service not run optimally if it has many users. Using MySQL as a database can be a solution to this problem. When using the DHCP Accounting feature, data from DHCP Accounting will be sent and centralized on Freeradius. Accounting data centralized on Freeradius will be stored using a MySQL database so that the available storage space will be much larger and can accommodate more data from DHCP Accounting, as well as monitoring the network so as to improve network security for users.]]>

<![CDATA[The advancement of information technology has driven innovation in various sectors, including the culinary industry. Semarang Regency, as a culinary tourism destination, offers a wide range of dining options that often make it difficult for tourists to decide where to eat. This study aims to implement and analyze the performance of a Telegram-based chatbot using the Rasa framework as a culinary recommendation medium in Semarang Regency. This chatbot is designed to provide quick and relevant culinary recommendations according to user preferences through the utilization of Natural Language Processing (NLP). The system development was carried out through several stages, starting from user needs identification, system design, chatbot implementation, to testing using the System Usability Scale (SUS) method. The test results showed that the developed chatbot achieved an average SUS score of 79.16, indicating that the system meets feasibility standards and provides a satisfying user experience. Therefore, this chatbot is effective in helping people quickly, flexibly, and efficiently find culinary recommendations in Semarang Regency.]]>

<![CDATA[The development of information technology has made the security and integrity of digital information exchange on websites extremely important. Many websites utilize Content Management Systems CMS like WordPress as an alternative choice. This research aims to conduct penetration testing on the WordPress based website teknoblog.top using the Penetration Testing Execution Standard PTES method and provide recommendations for improving existing vulnerabilities. The analysis results on teknoblog.top using the WPScan tool found 6 informational findings, which do not indicate vulnerabilities. Meanwhile, OWASP ZAP identified vulnerabilities with a total of 3 medium level alerts, 5 low level alerts, and 6 informational alerts. The vulnerability successfully exploited in this research was the Missing Anti Clickjacking Header with a medium level severity. This finding was confirmed using the BurpSuite Scanner tool. The vulnerability was caused by the website not properly configuring the security header. To verify the accuracy of the Missing Anti Clickjacking Header vulnerability findings on the OWASP ZAP scanning tool, exploitation was carried out manually using a simple HTML script and through the clickjacker.io website. It is important to address this issue to prevent web pages from being loaded in iframes on other websites. The recommended fix for this vulnerability is the addition of the X Frame Options header to protect the website from clickjacking attacks.]]>

<![CDATA[Classroom 4.3.4, 5.3.2 and 6.3.3 is used as a classroom for teaching and learning at SDN PINANG 03. The focus of discussion in this study is the illumination and lighting systems in the classroom. Illumination that occurs in the classroom does not meet standards, illumination for classroom lighting is 250 lux - 300 lux, the amount of light points is not in accordance with the standard calculation, finding some space with lighting installations are not designed in groups. One attempt to correct this condition is to make proposals optimization. The first optimization is to replace the existing types of lamps with 36 watt fluorescent lamp, with the number of lights installed at each point lights (luminaire) by 2 pieces and the number of points of light used is the number of point lights existing condition. The second optimization is to use the same type of lights to the existing condition is a downlight Philips Essential 23W Energy Saver E27 220-240V 50-60 Hz Cool Daylight lamp with a number of points based on standard calculations. The third optimization is to replace the existing types of lamp with 36 watt fluorescent lamp with a number of lights installed at each point lights (luminaire) by 2 pieces and the number of light points in accordance with accounting standards. The study was done by measuring the strong lighting in the classroom by means of a lux meter, analyze case studies on existing conditions with the theory. Then the results of these measurements will be compared with the illumination calculations in accordance with the standard formula, which in turn will get to do some optimization. The results of this study showed a strong improvement of the optimization of the value nearing illumination standards and meet the standards. Optimizations that meet the standards is the third optimization with a illumination value on classroom 4.3.4 is 257 lux , classroom 5.3.2 is 278 lux and classroom 6.3.3 is 317 lux. Values obtained from this optimization are powerful illumination range of 257 lux to 317 lux. It can be concluded that the results of this optimization meet strong standards for classroom lighting.]]>

<![CDATA[Cats in Latin is Felis silvestris catus is a kind of carnivorous animal. Cats are the most popular pets in the world that have many enthusiasts and fans. Cats that have bloodlines are officially registered as purebred cats or pure breeds. The number of cat breeds like this is only slightly, only 1% of the world's cat population, which is usually only bred in official animal husbandry. This study uses the Principal Component Analysis (PCA) and K-nearest Neighbor (KNN) algorithms with the aim of classifying cat images through the analysis stage on original images, binary images and grayscale images.The output of the feature extraction will be the input for the Principal Component Analysis (PCA) and K-nearest Neighbor (KNN) algorithms for cat species classification applications. The feature extraction that will be used in this research are RGB and HSV. The data that will be used in this study are 34 image data, consisting of 24 training data images and 10 test image data.So with this research, it is hoped that it can help people to more easily find out the classification of pets, namely cats. The output accuracy in the classification application uses the Multi Support Vector Machine (SVM) Algorithm with first- order feature extraction from the Principal Component Analysis (PCA) and K-nearest Neighbor (KNN) algorithms, which reaches an accuracy rate of 80%.]]>

<![CDATA[StudyThis contains about the detection of circular object images. The circular object tested is the moon image object, the moon image was chosen because the moon image has various moon shapes, namely the full moon, half moon and crescent moon. To detect the shape of the circular object image, several stages are carried out by starting the image segmentation process. (1) The segmentation process using the bi-level thresholding method makes the image black and white, (2) after that the image is repaired with the morphological process of the opening and closing methods. (3) For training data, the shape extraction process is carried out, namely the circular nature of the object (circularity) to determine the roundness of an object. For the testing process, the same process is also carried out as the process of obtaining circular image detection.]]>

<![CDATA[Skin color detectionis one of the segmentation processes that separates object regions in an image based on color differences. Objects that have a certain color are separated from objects that have other colors. The segmentation results can be used for further processes such as feature extraction or image classification. In this example, skin color is defined in the YCbCr color space with a Cb value between 77 and 127 and a Cr value between 133 and 173. Skin color detection is one of the initial stages in computer vision to detect things related to humans (people detection). Skin color detection can be used as a segmentation method for face recognition or recognition of other body organs. The system can be further developed for biometric systems.]]>
