Abstract

The aims of this research are to implement Support Vector Machine for analyze abnormal data on sensor network and evaluate the implementation result. The data collection in the research were done through the searching of related libraries and software evaluate/testing. In this research, temperature, wind speed, and humidity tested using three kernels (linear, Gaussian, and polynomial). Evaluation result show that the implementation of Support Vector Machine can perform the best data validity analysis using Gaussian Kernel with the percentage of average accuracy, temperature 97.83%, humidity 94.5325%, and wind speed 96.93% for weather data 20-28 May and July 28-August 10, 2015. Meanwhile, for weather data June 5-6, 2017 obtained the percentage of average accuracy of temperature 92.855% and humidity 92.43%.

Abstract

At a wedding there is a guest book to fill in so that the party organizers find out who the guests are. The length of filling in the guest book makes the queue quite long. The purpose of this study is to design and build an application system for android guest-based data collection using the QR Code that is used to replace the guest book filling. The research begins by designing ERD and Activity Diagrams. Then it is implemented into two programming languages namely PHP and Kotline and MYSQL database. Based on the results of the study, the author has succeeded in building an android-based guest guest data collection system application using the QR Code.

Abstract

This study aims to add a new type of sorting to the Ayosports startup where this new sort combines several types of sorting owned by competitors by building a decision support system in choosing sports fields. The decision support system is made using the Analytical Hierarchy Process (AHP) method using four criteria, namely rental prices, facilities, services, and types of fields. The alternatives used are three sports fields for each Ayosports category, namely basketball, badminton and futsal, so there are nine fields in total. The calculation results from the system that has been built show the same results as manual calculations using Ms. Excel. Then this system will be implemented on Ayosports when users search for empty fields and immediately sort them

Abstract

The purpose of this research is to analyze website vulnerabilities to avoid cyber attacks, especially on cross site scripting &sql injection types by applying OWASP Top 10 2017 rules to find security gaps by performing automated scans using ajax spiders after which active scans and manual scans use fuzzer to perform more specific exposures to cross-site scripting (XSS) and SQL injection types. After testing the web RenovAction vulnerabilities found Cross-Domain Misconfiguration, Secure Pages Include Mixed Content, X-Frame-Options Header Not Set, Absence of Anti-CSRF Tokens, Cookie No HttpOnly Flag, Cross-Domain JavaScript Source File Inclusion, Incomplete or No Cache-control Header Set, X-Content-Type-Options Header Missing, Charset Mismatch, dan Information Disclosure - Suspicious Comments, Timestamp Disclosure – Unix., in addition to getting vulnerabilities in the RenovAction web, the author also provided a solution to overcome vulnerabilities in the RenovAction web based on the Zed Attack Proxy (ZAP) tool.

Abstract

This study aims to utilize the support vector regression (SVR) method as a machine learning technique to predict the selling price of laptops and their level of accuracy. Data collection is done through literature, internet and evaluation with MAPE. In this study the authors made the Laptop Price Prediction application using Pycharm with the Python programming language. The test results show that the calculation of the analysis performed by the application produces the same optimization value as the calculation done manually by the MAPE formula, which is 98%. This research was conducted on several online laptop sales webs, such as Tokopedia and Bukalapak. Laptop sales data are collected from online sales webs, used as a basis for experiments. Evaluation The results show that from testing 8 test data the best percentage of accuracy was obtained using MAPE, which is 74%.

Abstract

Penelitian ini bertujuan untuk menerapkan metode Certainty Factor pada sistem untuk diagnosa penyakit diare pada anak dengan membuat aplikasi menggunakan permrogramman android. Hampir semua orang tua pasti khawatir jika anaknya terkena penyakit, apalagi penyakit itu adalah penyakit yang sangat sering dan banyak anak alami. Disaat yang bersamaan orang tua anak bukan seorang perawat pasti kekhawatiran akan semakin kuat, sistem ini bertindak layaknya seorang pakar atau ahli, dimana pada sistem ini terdapat gejala-gejala dari diare yang penulis dapatkan langsung dari hasil wawancara dengan dokter spesialis anak di tempat penulis melakukan penlitian. Metode Certainty Factor digunakan untuk menghitung probabilitas dari kehadiran berbagai gejala penyakit dengan memperhatikan gejala-gejala yang dialami. Hasil dari implementasi sistem dengan menerapkan metode Certainty Factor untuk diagnosa penyakit diare pada anak menunjukkan bahwa metode ini mampu memberikan hasil diagnosa sementara beserta nilai probabilitas kemunculan setiap jenis penyakit, dan sistem ini dapat memberikan informasi awal atau diagnosa sementara mengenai kemungkinan penyakit yang dialami oleh anak tersebut, dan Hasil Diagnosa terakhir tetap ada pada pemeriksaan langsung dokter spesialis.
