In order to reduce the spread of the corona virus in office areas, malls or housing, a sterilizer chamber is installed. It is used to detect someone who will enter an area and he must be sterilized first by spraying the entire body with disinfectant liquid automatically. By combining the sterilizer chamber tool with IoT technology, the sterilizer chamber tool can be monitored continuously at a certain distance using a sensor as a detector which will provide information to one of the operators of the tool condition, about the remaining liquid, the number of people who have been sterilized. The system works by providing information on the liquid spray time of about 5 seconds and information on the liquid level in the tube from level 5-70. The average output pin voltage is 4.89 V when the sensor detects an obstacle in front of the sensor and the NODEMCU will receive a voltage 4.89 V from the output pin and ultrasonic sensor HC-SR04. The highest voltage reaches 673.2 Mv, when the distance to the object is 40 cm with the lowest voltage is 100.3 mV with the closest distance being 5 cm.

Keyword research is one of the essential activities in Search Engine Optimization (SEO). One of the techniques in doing keyword research is to find out how many articles titles on a website indexed by the Google search engine contain a particular keyword or so-called "allintitle". Moreover, search engines are also able to provide keywords suggestion. Getting keywords suggestions and allintitle will not be effective, efficient, and economical if done manually for relatively extensive keyword research. It will take a long time to decide whether a keyword is needed to be optimized. Based on these problems, this study aimed to analyze the implementation of the web scraping technique to get relevant keyword suggestions from the Google search engine and the number of "allintitle" that are owned automatically. The data used as an experiment in this test consists of ten keywords, which each keyword would generate a maximum of ten keywords suggestion. Therefore, from ten keywords, it will produce at most 100 keywords suggestions and the number of allintitles. Based on the evaluation result, we got an accuracy of 100%. It indicated that the technique could be applied to get keywords suggestions and allintitle from Google search engines with outstanding accuracy values.

Enhanced Interior Gateway Routing Protocol (EIGRP) is a routing protocol that can be used to determine the path of data to be sent. EIGRP can achieve goals and study interconnected networks to obtain useful information to determine the best path. EIGRP is only adopted by Cisco routers or can be called a Cisco Proprietary Protocol, which can only be used on Cisco router devices. Currently, the EIGRP routing configuration uses the command line. For this reason, a Website-based EIGRP system was created and can be accessed remotely (remotely) with the aim of providing freedom of access and not focusing on one device. Website-based EIGRP system was created by utilizing Cisco's API as a liaison between the programming language and Cisco Router 2811 software. Telnet utilization plays a very important role in creating a Website-based EIGRP System where Telnet can provide wider access in management. By visiting the host and port of the router, the EIGRP Website Based System can easily do this. The results of the test in this study indicate that the Website-based EIGRP system is proven to be able to configure, so that administrators can use it for device management of Cisco Router 2811.

Image segmentation is a concept that is often used for object detection. This detection has difficulty detecting objects with backgrounds that have many colors and even have a color similar to the object being detected. This study aims to detect fish using segmentation, namely segmenting fish images using k-means clustering. The segmentation process is processed by improving the image first. The initial process is preprocessing to improve the image. Preprocessing is done twice, before segmentation using k-means and after. Preprocessing stage 1 using resize and reshape. Whereas after k-means is the contrast-limited adaptive histogram equalization. Preprocessing results are segmented using k-means clustering. The K-means concept classifies images using segments between the object and the background (using k = 8). The final step is the morphological process with open and close operations to obtain fish contours using black and white images based on grayscale images from color images. Based on the experimental results, the process can run well, with the ssim value close to 1, which means that image information does not change. Processed objects provide a clear picture of fish objects so that this k-means segmentation can help detect fish objects.

Bisma Informatika is one of the educational institutions with Diploma education level in Denpasar that serves certification services for people who want to take certification expertise, especially those engaged in Information and Computer Technology. In order to serve optimally, Bisma Informatika applies registration which can be done by the computerized system so that the participant's data can be stored properly. After observing the use of the system at the time of participant registration, an initial conclusion can be drawn that many data fields cannot be understood by the user so they must ask the officer on duty. The data fields in question such as the choice of certification class are not clear because it does not include the implementation time, the unaccompanied participants who come from the common line (so can not include the student identification numbers), telephone numbers that cannot be entered if they exceed the capacity of the permitted number, and inconsistent field filling instructions. This shows that the usability aspect of the registration system is not being considered properly. This study evaluates the interface design and features of the Bisma Informatika certification registration system by considering the context and user needs. In an effort to find out the context and user needs, a Website Usability Evaluation (WEBUSE) questionnaire was used. The results of the WEBUSE questionnaire showed that the four categories which have a good usability level, only content, organization and readability categories are obtained.
