<![CDATA[The number of cases of Covid-19 in this pandemic era is increasing and getting out of control every day. This triggers the Indonesian government to set policies on schools with online learning methods. Of course, online learning cannot ensure that it runs smoothly in all circles because several factors hinder the learning process. The difficulty of the internet network, limited quotas, unfamiliarity with the use of learning media, and an unsupportive environment for conducting online learning are the obstacles to ineffective online learning. The purpose of this study was to determine the level of satisfaction with online learning during the pandemic. This study uses quantitative research methods with a descriptive approach. Quantitative research methods will be processed into data mining using the K-Means Clustering Algorithm. The clustering process is carried out to get the results of clustering the level of student satisfaction. The dataset was obtained from the results of the questionnaire by submitting statements of satisfaction and dissatisfaction. The cluster type is based on high, medium, and low class. The test results obtained a value with the final iteration, namely the level of satisfied statements is categorized as high with a value of 11.79 compared to the dissatisfied statement, which is categorized as moderate with a value of 7.46. In contrast, for the low category level, there is no value of 0.00 cluster results state that the category is satisfied with online learning with a value of 9.33.]]>

<![CDATA[Advances in information technology have had a tremendous impact on all of the professions today. All buying and selling activities, including selling baby products, have become easier with digital technology, namely the marketplace. Until now, the marketplace business only uses a physical storefront and marketplace to offer their wares. However, there are still obstacles such as the lack of product information obtained by customers due to decreased sales, lack of a wide range of promotions due to lower income, and discounts when using the marketplace due to lower marketplace revenue. Based on the problems mentioned above, an e-commerce website is needed to solve the problem in the Mimimama store. This e-commerce website is built with the WordPress Content Management System (CMS), and the Business Model Canvas (BMC) method is used to analyze the business model. Designs are built using the Unified Modeling Language (UML), and websites are tested using Usability Testing to ensure the functionality works properly. After the website is built, SEO is applied using On-Page SEO to optimize website pages. Google easily indexes them and is easy to find by customers using certain keywords. The development of an e-commerce website provides answers to make it easier for customers to access information, expand marketing reach, and allow Mimimama to focus more on building the Mimimama store brand.]]>

<![CDATA[Unmanned Aerial Vehicle (UAV) is an unmanned aircraft system that is no longer a special need but has become a general need for the community, and one example is used to capture everyday moments through photos or videos from the air. Among the models of UAV aircraft is the quadcopter, where there is a flight controller that functions to fly the quadcopter by adjusting the speed of each motor. The flight controller that is often used today is the Pixhawk manufacturer. The Pixhawk module is an integrated system that the factory has provided, so it cannot be modified in terms of control and I/O. This research focuses on making an independent flight controller that can be used to fly a quadcopter. The control method that is implanted is Proportional Integral Derivative or commonly known as PID. The flight controller uses the PID control method to adjust each Brushless DC Motor (BLDC) speed to maintain stability while flying. From the test results, the quadcopter can fly stably with KP parameters of 2.5, KI of 0.6, and KD of 1.0. The response time in processing feedback is 3s.]]>

<![CDATA[Water dispensers are electronic devices that are widely available in households and offices. In general, water dispensers use faucets to drain water. During the pandemic, many people avoid touching equipment used by many people. Various ways have been done so that the water dispenser can be operated automatically without touching the faucet. Previous research on water dispensers was only applied to one type of water. This study aims to make an automatic water dispenser without touching the faucet used for two types of water, namely hot water or cold water. This research is based on hand gesture detection to choose hot water or cold water. The APDS-9960 gesture sensor detects hand movements to select hot or cold water, and then a servo motor is used to open the water faucet. After that, the position of the glass is validated by the ultrasonic sensor HC-SR04, and water will flow for 30 seconds into the glass. The entire input and output process is controlled using Arduino. The results show that this automatic water dispenser can detect hand gestures at a maximum distance of 15 cm with a hand movement speed of 2 to 3.7 seconds. This automatic water dispenser can detect three kinds of glass, namely ceramic, clear glass, and plastic, at a distance of 1 to 3 cm, and the volume of water flowing for 30 seconds is 240 ml.]]>

<![CDATA[Gamification has been widely adopted in many areas, including in the educational context. The students need to be motivated in following the learning process because everyone feels happy to learn if there is no coercion. By presenting something fun and enjoyable, students are expected to be more involved in the learning process, which will achieve better learning outcomes. Gamification is very reliable in bringing fun and pleasure to the learning process for the students. We analyze three items from the previous study; the intention and what the goals are expected, how to design, and the result of gamification in the education context. We found the intentions of gamification adoption in an educational context. They are to increase students' motivation to learn and present an alternative learning method that is more fun and enjoyable. And for the success of this gamification program, a game application can be developed using existing sophisticated technology and by presenting a reward system mechanism. The presence of points, badges, and leader boards cannot be separated from the gamification because it is a very inherent gamification feature to motivate students to play the game. Getting students to use the games intensively is not the only result we expect, but it also makes students learn better to produce good learning outcomes.]]>

<![CDATA[Traditional cryptographic approaches such as symmetric and asymmetric cryptography are commonly employed to solve network security issues. The Secret Key Generation (SKG) system has the advantage of extracting secret keys from a wireless channel's physical layer information. It allows two wireless devices within the transmission range to extract a shared symmetric key without the use of a fixed key distribution infrastructure, allowing vehicular ad hoc networks to exchange information (VANET). This study aims to create a secure data communication system on the Vehicular Ad-Hoc Network using RSS Key Generation. Starting from the Modified Quantization Log, the results of the Modified Quantization Log show that the average KDRM between Alice and Bob is the average KDRM between Alice and Bob is 9.4%; meanwhile, the average KGR is 71.4 bps. This shows that the number of bit mismatches after the Modified Quantization Log process between the two valid users is already small, because they have used the pre-processing process in front of them, namely using the Kalman Filter and from the results of the BCH Code to be matched again so that it becomes the key. The next process is Universal Hash which is tested with the NIST test. The NIST Test parameters used are approximately entropy, frequency, block frequency, longest run, cumulative sum forward, and cumulative sum reverse. The existing results are appropriate; namely, the threshold in p whose value is above 0.01 is achieved. From the results of the Average Approximate Entropy, it is found that the largest value is obtained by the 40k10ms scheme, which is 0.7352.]]>
