Abstract

The need to analyze a product or policy becomes an important thing to measure the level of success. Twitter is currently one of the popular applications used by the public to give their impressions and opinions, both positive, negative and neutral opinions. Diverse public opinion on Twitter can be used as a reference material to get the level of community satisfaction on a product, service or policy. In this study, a sentiment analysis system was created using the TF-IDF and SentiStrength Algorithm. The steps in the research are, firstly, crawling Twitter data using the Twitter API, second preprocessing, thirdly doing spell correction, fourth Word weighting (TF-IDF) and lastly SentiStrength classification, where the results of the classification of tweets have positive, negative or neutral sentiments. In the test data taken using the keyword "child vaccines" as many as 1000 tweets, the results obtained were 54% positive sentiment, 20% negative sentiment and 26% neutral sentiment. Comparison with the same negative data analysis using a different algorithm, namely Naïve Bayes, results in positive sentiment of 55%, 16% and neutral 29%. Decision Tree got 61% positive results, 14% negative and 25% neutral.

Abstract

Technology for document management is really need because it can improve performance both in storage, search and document security. Document management in a manual way can waste time in finding required documents and requiring a lot of space for hardcopy document storage. This study uses a string matching algorithm combined with ROT13 algorithm. String matching algorithm is used to find a file name in database, the file name in database has been encrypted for example plaintext “Kabel Ladder” into chipertext “Xnory Ynqqre”. The steps of string matching algorithm combined with ROT13 algorithm in this study are, word pattern is encrypted and then matched with existing data in database and then a string search in performed using string matching algorithm and produces the data sought. In both algorithm, time and number of matches were tested between pattern and data to show performance of two algorithms using 200 data until 500 data. The result of testing 200 data for search word Tower takes 0.00513 sec and matches 65x, 300 data for search word Tower takes 0.00716 sec and matches 164x, 400 data for search word Tower takes 0.01372 sec and matches 262x and 500 data for search word Tower takes 0.02233 sec and matches 360x. From the test result in this study, the researchers concluded that string matching algorithm combined with ROT13 algoritm, the more data, more time it will take, even though it is still relatively small

Abstract

The facilities in the laboratory can make students especially feel comfortable because of several supports such as internet availability, better computer specifications, servers with large capacities as data storage media and rooms that support students' conditions in doing their assignments. During the pandemic, the laboratory cannot be used optimally because learning is done online. So that an online application for borrowing a laboratory is needed to maximize the function of the laboratory. In this study, a laboratory loan website application was designed by combining sequential search and bubble sort algorithms on the search engine menu so as to facilitate and speed up the process of searching for laboratory types. The test was carried out simultaneously from 700 test data and resulted in a time of 3 milliseconds for the sequential search algorithm, and 0.036 milliseconds for the bubble sort algorithm. While the results of the testing time with the combination of the two algorithms obtained are 4 milliseconds

Abstract

There is a sales system called Flash Sale in e-commerce. Basically the concept of a Flash Sale is to offer a lower price and a predetermined time and number of products. The sales system is only held at certain moments, by making cheaper product sales but with a limited time and number of products it will make sales increase because buyer interest will be higher. But apart from all the advantages of course there will be pros and cons. Sentiment analysis on Twitter was chosen because Twitter itself is a social media that allows users to be free to comment or write opinions about anything, including opinions about flash sale events that exist in e-commerce today. Thus, this research exists to find out the opinions of existing Twitter users regarding the Flash Sale event held by e-commerce. By using the methodology of three classification algorithms, Naive Bayes, K-Nearest Neighbor and Random Forest in classifying the data to determine the accuracy of the sentiment value of Twitter users in the Flash Sale event. This research takes two data samples from the keywords "flash sale" and "flash sale shopee", the results accuracy of the implementation of the three classification algorithms are 83.53% Naive Bayes, 82.94% K-NN, 80.59% Random Forest for the keyword "flash sale” and 81.48% Naive Bayes, 77.78% K-NN, 74.07% Random Forest for the keyword “flash sale shopee”. With this, the Naive Bayes Algorithm becomes a recommendation for classifying Sentiment Analysis data with greater accuracy and more stability to be used for large and small data.

Abstract

Humans can produce waste every day, both household waste and industrial waste which has various forms and types. Garbage can be a problem because it interferes with human health, causes unpleasant odors and air pollution. Awareness of disposing of waste in its place is currently considered very lacking. This is because trash cans in general still use a simple way, namely by opening and closing manually. In the design of this smart trash can it will facilitate the work of the cleaning agency. In this study, a smart trash can with HC-SR04 sensor was designed using Arduino Uno R3 With the HC-SR04 sensor, it can detect the distance of humans who want to throw away and detect garbage loads. The maximum and minimum distance from the sensor is 10-60 cm to open the lid of the trash can. Data processing uses Arduino Uno R3 with Atmega328p chip which functions as data processing and sending data. The testing process that is carried out periodically produces data in the form of differences in the original distance and the distance read by the sensor with a difference of 0-1 cm, while the minimum and maximum sensor distances are 10-60 cm. This system can also detect the garbage load if it is full and will send a notification in the form of SMS. Another benefit is to make people aware of the importance of health by disposing of waste in its place. The method used is the waterfall method to detect this object is the design method which consists of several stages, namely Requirements Analysis, Design, Circuit Implementation, Test Tools.
