Nowadays WiFi technology is increasing with the people's need for internet access. WiFi is an abbreviation of Wireless Fidelity. WiFi can be said to be a technology for exchanging data by utilizing radio waves (wireless) that can be used by several electronic devices such as computers, smartphones, tablets, and so on. This research tries sniffing method on WiFi-based 802.1X protocol to get the client authentication code. The conclusion obtained from this study is the Sniifing Process using the Wireshark application managed to get the station authentication code on an 802.1X-based WiFi network. The authentication code can be used when the station is no longer connected to a WiFi network. This can be used by other people or stations that are actually not entitled / illegitimate.

Depok Madani Vocational School is a Vocational High School consisting of 2 majors namely Light Vehicle Engineering (TKR) and Computer and Network Engineering (TKJ) with 20 teachers as instructors from class X to class XII. The selection of the best teachers is done once a month to motivate the teacher in conducting teaching and learning activities. Schools in making decisions are often influenced by subjectivity and are done manually. Resulting in social jealousy among teachers and inaccurate decision results. Therefore, in assessing the best teachers a decision support system is needed in order to obtain accurate results. Decision Support System methods used in this study is Profile Matching. The method determines the value of weights on each criterion, which is to be present on time, responsibility, dress neatly and politely, participate and contribute, be active and productive, and help fellow teachers, which is followed by a ranking process. The result of the comparison of the two methods above is to produce the same chosen alternative, so that both methods can be applied to help the school's decision making.

By using data mining methods can be processed to obtain information and assist in decision making, the amount of data on sales transactions in each drug purchase can cause a data accumulation and various problems, such as drug stock inventory, and sales transaction data, with Data mining techniques, the behavior of consumers in making transactions of drug purchase patterns can be analyzed, It can be known what drugs are commonly purchased by mostly people, the application of Apriori Algorithm is expected to help in forming a combination of itemset. The process of determining drug purchase patterns can be carried out by applying the Appriori algorithm method, determination of drug purchase patterns can be done by looking at the results of the consumer's tendency to buy drugs based on a combination of 3 itemset. By calculating the Analysis of High Frequency Patterns and the Formation of Association Rules, with a minimum of 30% support, there is a combination of 3 itemsset namely MOLAGIT PER TAB (M1), VIT C TABLET (V2), and PARACETAMOL 500 MG TABLET (P2) with 33.33 % support results obtained, and with minimum confidence of 65% there are 6 final association rules.

Geographic Information System ia a geospatial software system that has the ability to build, store, manage and display geo-referenced information, for example data that is identified by location. By using GIS, it is expected that it will be easier for prospective students and students to find out the location of boarding houses that are located around the campus of Mulawarman University. The system development method uses the waterfall method. While the system design method uses UML (Unified Modelling Language) to visualize, determine, develop and document a software system. The algorithm used in this study uses the haversine formula which will later help to find the nearest boarding house location around the campus of Mulawarman University, the haversine formula will produce the shortest distance between two points, for example on a ball taken from the longitude and latitude. The result of this study will disply detailed boarding location information, besides that on this geograpihic information system the user will later be able to see the details of boarding and admin data can change, add data to the boarding owner and be technically responsible for the running of the application, while the boarding owner is only responsible on managing boarding data on their respective users.

Attendance is a document that represents each employee at the company or representative. Some of the challenges experienced by KSPPS BMT INSAN MANDIRI are marketing that is difficult to carry out attendance when coming out of the office because of increased marketing activities that are directly related to members / out-of-office expenses. Therefore the researcher got findings to solve the problem that occurred by making an Android-based online attendance application that can be connected directly with the sarver provided by the office. This application is equipped with the introduction of security and the use of manipulations made by employees, and this application is equipped with monitoring features so that marketing managers and managers can set marketing positions in realtime. In this study, researchers used HTML and PHP programming languages for web applications that use presence servers / data centers, webside uses Google map APIs to obtain marketing positions, and presence reports can be purchased from the webside. The hope of this research is that the online android mobile attendance application with face recognition security can run well and meet the needs of the KSPPS BMT INSAN MANDIRI.

The AHP (Analytical Hierarchy Process) method is suitable for the decision making process because it can determine scores for each different criteria, then proceed with the best alternative selection process. In the SPK (decision support system) is used web-based that can be accessed anytime, anywhere. So that at school, high school students (high school) can access the system through the school's computer. Requirements analysis is divided into 2 types, namely functional requirements (Functional Requirements) are types of requirements that contain the processes that will be carried out by the system and non-functional requirements (Non Functional Requirements) are types of requirements that contain behavioral properties owned by the system. Criteria for test results is a requirement for decision makers in determining the selection of study programs in Higher Education, based on the DAT test, the results of which are divided into 3 criteria, namely verbal ability, numerical ability, and spatial ability. Of the 100% accuracy of the results on the system using the AHP method in this system only results in 75% of the accuracy of the results.

Nursing Diploma Degree Student Competency Test which has been done since 2013 is still found by students who have not passed. This makes the nursing college conducting the competency test have to think of corrective steps so that in each period of the competency test there are no more students who do not pass. One way to do this is to make predictions on the results of the competency test using the Adaptive Neuro Fuzzy Inference System (ANFIS) Method. The data used are past data from the results of the Nabila Nursing Academy competency test results from 2015 to 2019 totaling 146 data. The variables used are gender, participation status, academic achievement index (GPA), and follow the tryout. For ANFIS training data were used 50 data and 96 data for testing data. Obtained a minimum error of 0.00% and a maximum error of 0.94% and a MAPE value of 0.11%. With a small MAPE value it can be concluded that ANFIS can predict the results of competency tests in nursing diploma degree students.

This criterion will be the basis for choosing a location, and of course in choosing a location takes a long time because the criteria given can be very diverse. To be more effective and efficient, a Decision Support System (DSS) is needed that serves to help entrepreneurs in determining which location is most suitable. In this research the method in spk used is Simple Addidtive Weighting (SAW). SAW processes data by giving weight to the criteria used as a reference in decision making. After that, a matrix of decisions is made based on criteria. The results of the research can be the best recommendation for entrepreneurs to establish a strategic place of business in accordance with their wishes. The sequence of location selection resulting from the application of this SAW method is Teluk Naga with a final result of 6, followed by Poris with a final value of 5.66667, and lastly Dadap with a final value of 5.
