Abstract

In the digital era, data is at the core of business continuity. The need for fast, precise and accurate information is needed. Cars are one of the tertiary needs. This means of transportation is a relatively fast development and innovation business. Car sales in Indonesia recorded a reasonably high number in 2014 - 2018, namely 4.157.580 units sold. The highest sales were MPV car types being the most popular type of car, and there are many types of cars in Indonesia, including Sedans, SUV, 7 Seater SUV, and City Car types, and the enthusiasts need to play more. Hence, it is exciting to study. The variety of car brands with competing prices makes it difficult for consumers to choose the right car to buy according to their needs. This can be solved by applying data mining to cluster car sales using the k-means clustering algorithm. The goal is to know the characteristics of the car from each attribute. The k-Means algorithm is used for cluster formation based on five attributes: CC, Tank Capacity, GVW (Kg), Seater, and Door. The elbow and silhouette score methods determine the optimal number of clusters (k). The result is 4 clusters, cluster 0 (High-Performance Heavy Car), cluster 1 (Small Family Car), cluster 2 (High-Performance Small Car), and cluster 3 (Medium Performance Car). The 4 Cluster results are based on the evaluation/validation of the Elbow Method and Silhouette.

Abstract

PT Indotruck Utama utilizes the 802.11n network only as an internet medium, without thinking about a sufficient security system for offices or companies. By only utilizing the 802.11n network which has poor security, it affects many illegal users who can enter the wireless network and can interfere with the performance of employees who are working. The purpose of this study is to produce a RADIUS-based authentication system that is used to improve wireless network security systems, namely being able to make a user have to login authentication twice, create different usernames and passwords for each user, prevent the entry of illegal users, and facilitate administrators in user management. In designing FreeRADIUS as a user manager on this proxy hotspot network using the NDLC (Network Development Life) method through 6 stages, namely analysis, design, simulation prototype, implementation, monitoring, and management. However, its application is only carried out until the implementation stage. This authentication system can be one solution to solve some problems that exist in the wireless network at PT Indotruck Utama. The test results from the capture on the wireshark application that uses PAP authentication still see the username and password, while those who use CHAP authentication only the username is visible, while the password is not visible because it has passed the encryption process.

Abstract

Nurul Izzah Kindergarten is one of the kindergartens located in Deli Tua District, Deli Serdang Regency, North Sumatra. Nurul Izzah Kindergarten has an educational concept of learning either religion or other general education without losing the playful children's world. However, the Deli Tua District community in Deli Serdang Regency is not very familiar with Nurul Izzah Kindergarten, therefore promotion is needed. In this matter, a decision support system is necessary on aiming to recommend the priority of media promotions using the MOORA method. The MOORA method is used to calculate the weight value of each attribute, then the process of which alternative ranking is the most recommended according to the results of the highest Yi calculation, some of these alternatives are Tiktok, Instagram, Facebook, Brochures, and Posters. For recommendations for promotional media, several criteria are required such as the cost, reach, attractiveness, and completeness of information. Based on the calculation of the MOORA (Multi-Objective Optimization based on Ratio Analysis) method for each alternative, the highest Yi is Tiktok with 0.3306 and the second highest Yi is Instagram with 0.2956.

Abstract

Cloud computing is currently being developed and widely used by companies that require large and efficient computing resources. As technology evolves, security threats in cloud services continue to increase. Various threats in cloud computing technology can be avoided by maximizing the identification of security holes. Information threats associated with cloud computing require network and service security against possible attacks. Suricata is a threat detection identifier supported by existing rules. When an attack is detected, Suricata will create a log of the attack committed, Suricata can also perform automatic detection at level 7. The author collected the results of the attack in a log. Sign Suricata and the authors also evaluate whether Suricata can detect port scanning, brute force, denial of service, and backdoors for Cloud Computing. From the test results, optimal results were obtained from the results of attacks detected by the Suricata Intrusion Detection System (IDS) logs in the /var/log/suricata/fast directory.log, the author added that the Suricata configuration is not only for detection, so it can also run drops if there is suspicious activity using network filters that already exist in Suricata and manipulated configuration assumptions to optimally improve security in the cloud.

Abstract

Gamification is an extraordinary phenomenon of how we can engage users to understand our Business. Users can get many interesting things from gamification offered by business owners, ranging from games, bonuses, discounts, and many other things that can make users or consumers more loyal and have a close relationship with the Business. This research is developing the concept of innovation profiling, which describes seven types of innovation. Here, gamification is one of the innovations we will discuss. This study divides gamification into three important parts, units that should not be separated. The first part concerns the big picture of gamification profiling and the Formula GMF = P. B2. E2. Ps2.F2. In the second stage, there are four types of gamification- open Gamification (OP), specific Gamification (SG), innovative Gamification (IG), and undeveloped Gamification (UG). The third stage, the final stage, is Business Gamification profiling (BG), Education gamification profiling (EG), Psychology gamification profiling (PG), and Future gamification profiling (FG). This research results in the gamification profiling framework and its application in education as the main case study in implementing this. Furthermore, Smart city and social profiling are two things that cannot separate from each other. Therefore, in building a smart city & social profiling, several important things must be considered, including investors, people, culture, supervision, customers, data, mapping, mentors, capabilities, commercials and leadership. This article will develop Business Model Mapping 101 (Smart City Maturity Level Mapping), an innovation in shaping and producing social profiling. Problems such as implementing smart cities in human resources, technology, and other factors are the main concerns. Therefore, Smart City Maturity Level Mapping is a social profiling development concept that focuses on building something from what the area already has. It is to increase the level of a more stable economy but remain flexible in dealing with certain situations. Furthermore, this article complements the previous article, namely smart city 5.0 (Human resource, Technology, marketing). These three things then developed into Smart City Maturity Level Mapping, which later became social profiling, which is useful for measuring smart cities' performance and implementation in a more structured, systematic and detailed manner in terms of profiles. The final result is the maturity level to measure a smart city's performance, which also connected to the defender, extender, dodger, contender.

Abstract

The cafe service system in this modern era still uses manual labor. This is less effective in terms of service speed and of course will increase operational costs due to the need for a large number of waiters. For this reason, an electronic food and beverage ordering device is needed. This is useful for speeding up the service process and also reducing service personnel, of course, also reducing operational costs. This research will present the use of the ESP 8266 module as a minimum system design for ordering menus on consumer tables. Input from the dining table containing the menu code and number of menus will be displayed on the LCD. Furthermore, data will be sent from ESP 8266 to the kitchen to mix food and drinks ordered by consumers. The data is also transferred to the cashier's PC, whereupon the cashier prints invoices for consumers. From the test results on the LCD can already display a menu of food and drinks. The cashier PC and kitchen PC have also displayed the food and drink data ordered. Cashiers can also print bills for consumers.
