PPKM until March 2021 was successfully implemented according to its objectives, marked by a decrease in the number of virus spread from Malang City initially being in the red zone to the green zone. Information development related to PPKM can be followed through social media. Twitter is a social media platform that connects users through instant and short message exchange communications. From social media Twitter users can send text messages called tweets with a maximum limit of using characters up to 280. Twitter as a social media to find out information and public opinion that develops about PPKM rules. Each tweet has a positive and negative sentiment value. Sentiment analysis aims to classify an opinion written through a tweet. This study analyzes tweets with the topic of PPKM Malang City. Sentiment analysis is carried out by classifying text data in the form of tweets into positive and negative sentiment classes. The classification process is implemented in RapidMiner Studio software with the K-Nearest Neighbor classification method and Chi Square feature selection. The main processes in sentiment classification are preprocessing, term or text weighting, feature selection and classification. Testing and analysis were carried out using three methods, namely testing based on comparison with manual calculations, testing based on variations in the value of k, and testing based on variations in the percentage of features. The best accuracy result from the classification process is 82%. The accuracy results were obtained during testing with a value of k = 3 and a feature percentage of 100%. The percentage of features used in the classification process affects the accuracy where the smaller the feature value used, the smaller the classification accuracy value.

This has an impact on decreasing revenue at Arofah Shop and for customers also experiencing difficulties in getting herbal medicine or Arabian snacks. To facilitate this, an e-commerce website was built using the prototype method complete with features of product management, admin, and transaction management systems. In addition, integration with Midtrans, a payment gateway transaction payment service provider, is also carried out. This website is tested using black-box testing and usability testing.

Abstract

“Suzuki Katang” Motorcycle Dealer is one of the Suzuki brand motorcycle distributors located in Kediri City which was founded in 2010. In its business process, namely bookkeeping, before using Microsoft Excel, dealers used the manual method using a notebook. In addition, they have also used the google form but it is not effective because they have to access a different google form for other types of data. If the service process does not run smoothly it will leave a bad score for the buyer. In addition, every month an evaluation is usually held by an official dealer. Which, if the evaluation of service evaluation and presentation of sales reports is not satisfactory, it will affect the capacity of the unit that can be ordered by the dealer as well as the limited cooperation carried out with other authorized dealers. From these issues, it is important to foster a business data framework for better information the executives.

Abstract

Alfa Setosa Farm is one of the chicken farming industries located in Bendosari Village, Kademangan District, Blitar Regency. Alfa Sentosa has been established since 2018 and focuses on producing chicken meat. Alfa Sentosa Farm has a total capacity of 7,000 (seven thousand) chickens for each production. The production period carried out by Alfa Sentosa is usually takes about 30 (thirty) to 40 (forty) days to produce chicken meat. Alfa Sentosa itself also partners with PT. Charoen Pokphand Indonesia for the supply of chicken seeds, feed, and vitamins. However, there is a problem with data recording which is still done manually using handwriting on an existing form. After writing the form, the employee takes a picture of the form and then reports it to the Alfa Sentosa farm owner via the online chat application. The report is divided into 3, namely the DOC (Day Old Chicken) report when it arrives, the daily report for feed and medicinal use, and the report when it is harvested. In addition, these reports are not well documented because they only use photos and are not neatly stored, making it a little difficult to analyze the percentage graphs of Alfa Sentosa farms. So from these problems, the development of an Information System for the archiving and recording of reports was carried out to help maximize business processes. System development begins with requirements analysis by interviewing Alfa Sentosa farm's owner. Based on the results of requirements analysis, it is continued with the design in the form of Sequence Diagrams, Class Diagrams, Physical Data Models, API design, and User Interface design. The system implementation is carried out in the form of mobile apps with the Laravel and React native framework. These two technologies will communicate using RESTFUL Web Service. For the testing, the blackbox testing is used, which gets all valid values and usability testing which gets average value 86 that means the system is well received.

To further facilitate transaction activities at the Rizza Collection Boutique, an e-commerce website that is integrated with the Midtrans payment gateway has been developed. Customers will find it easier to make payments without having to confirm to the admin, as well as make it easier to order clothing requests without having to come directly to the boutique.

Abstract

SMAN 9 Malang is one of the public schools owned by Malang City. Even though it is relatively new, SMAN 9 Malang always tries to implement various uses of IT in schools, such as in the multimedia-based study room and computer laboratory. Based on the results from the interviews conducted by the examiners with Wakahumas there, SMAN 9 Malang does not have a special information system used to manage student data there. The whole process of recording student data is still done manually. Whether it's attendance system, violation record, guidance record, and student achievement record is still done manually. Normally, the teacher takes data from the class manually, then gives it to the TU for further input into the Ms. Excel on the school's computer. This makes it just to see the data, you need to contact the TU or meet Wakahumas. In overcoming the problem above, a solution was made in the form of a student management information system that was built using the agile rapid prototyping method. At the analysis and design stage, a model is built that can be used as communication between researchers and stakeholders in order to find the best solution in system development. The models used at this stage include use case diagrams, use case scenarios, sequence diagrams, class diagrams, and physical data models. The system is developed using php with laravel framework for website and flutter for mobile. The system that has been built is tested using blackbox testing and user acceptance test (UAT). Blackbox testing showing valid in all tests and UAT testing scores 96.42% for teacher users and scores 87.60% for students users.
