Abstract

Agriculture has an important role in Indonesia's economic development as one of the contributors to the state budget which continues to increase every year. In the post-covid 19 pandemic, there were problems that disrupted the economy, impacted on other fields such as agriculture, where the problem of the food crisis would become a problem for Indonesia if it was not handled properly. Agricultural land tends to be increasingly limited because they have to compete for various uses, while people working in agriculture in absolute terms continue to increase causing land ownership to become increasingly narrow. An effective pakcoy planting solution can be planted using hydroponic techniques, so there is a lot of interest from farmers to cultivate pakcoy plants but these plants are susceptible to disease. This research was conducted to detect disease in Pakcoy. The process of detecting Pakcoy disease focuses on knowing the disease of Rotten Pakcoy leaves (Phytoptora sp.) based on the Color Space Hue Saturation Value or HSV. Implementing a simple image using image processing taken using a webcam camera then processed on the Raspberry Pi 4 Model B for detection of pakcoy disease then displayed on the LCD16x2. Based on the research implementation process from start to finish it is able to work as expected. The accuracy of the pakcoy disease detection system resulted in an average accuracy value of 85% for 2 types of classes and an average computation time of 0.001213 seconds for 10 tests.

Abstract

BCA Mobile and MyBCA are two mobile banking apps offered by BCA. Users of BCA Mobile have complained about issues with signal indicator lights, a large number of steps required and a lack of a "share" feature. On the other hand, MyBCA is favored by users due to its modern and attractive appearance, biometric login feature, and fast speed. However, it has limited features and a difficult registration process. This study used usability testing and Single Ease Questionnaire (SEQ) to measure the effect of the number of clicks and duration on user satisfaction for both apps. It also used the User Experience Questionnaire (UEQ) to measure user satisfaction based on attractiveness, perspicuity, efficiency, dependability, stimulation, and novelty. The study found that there were differences in the number of clicks and duration between both apps, with MyBCA having a lower average number of clicks and a shorter average duration. However, there was no difference in satisfaction between the two apps. The number of clicks and duration had no effect on user satisfaction for either app. The study revealed there are differences in attractiveness, efficiency, stimulation, and novelty, but no differences in perspicuity and dependability between the two apps. MyBCA had higher average scores on all UEQ factors compared to BCA Mobile, indicating that these factors influence user satisfaction for both apps.

Abstract

The digitization of the transportation system has encouraged online ticket booking platforms such as the RedBus application. RedBus helps the public to order tickets from various bus operators in Indonesia. Users can download and view reviews of the RedBus application through the Google Play Store. Reviews are important for both users and developers. However, there are users who give high ratings but have negative reviews. Therefore, it is necessary to analyze user reviews to classify these reviews into positive and negative sentiments class. The total data used is 500 reviews with details of 250 reviews in each positive and negative class. The stages for classifying are manual data labeling, text preprocessing to change the data to be more structured, weighting by the TF-RF and TF-IDF methods, classification by the Naive Bayes algorithm, and testing by the confusion matrix and k-fold cross validation. This study compares 2 word weighting methods, namely TF-RF and TF-IDF to obtain optimal accuracy results. The best accuracy results obtained were using the ratio of training data and test data of 90%:10% with TF-IDF weighting and cross validation testing with a value of k = 10. The average accuracy obtained is 93.56% accuracy, 93.97% precision, 93.57% recall, 94.68% specificity, 93.53% f-measure.

Abstract

Controlling the air quality of strawberry plants in a smart greenhouse prototype must be of great concern to strawberry farmers in order to get maximum yields. Air quality parameters that must be monitored, for example, are air temperature and air humidity as parameters that can affect the viability of strawberry plants. Given these problems, there is a need for research related to a system that can help answer these problems, namely the Smart Green House Prototype Control and Monitoring System on Strawberry Plants Using Fuzzy Logic Based on the Cayenne Application. The method used is the Mamdani fuzzy model to assist the control system in controlling air quality parameters in the smart greenhouse prototype, namely temperature and humidity parameters. The microcontroller used is Wemos D1R2 which can connect to the wifi network and can connect to Cayenne so that it can be monitored via Cayenne. The temperature and humidity sensor used is the DHT 22 sensor and based on the results of the test, it is obtained an error value range of 20,75% for temperature, while for humidity the DHT 22 sensor produces an error value of 18,7%. The test was carried out nine times in three conditions, namely cold, normal, hot for temperature and low, normal, high for humidity. The smart greenhouse prototype was also tested how effective the system is in controlling the environment by conducting experiments using actuators and without actuators. The results obtained from testing using the actuator, the temperature inside the smartgreenhouse can decrease by 2.13°C and humidity can increase by 5.1%. The second test was carried out without an actuator, so the temperature rose by 9.82°C and the humidity decreased by 22.16%.

Abstract

Authentication is an action taken to prove a user's identity when the user wants to enter a system or application, one of which is a mobile banking or m-banking application. Each m-banking application uses a different authentication method, for example, the authentication method for the BTN Mobile and Livin' by Mandiri applications. In the BTN Mobile application, the authentication method used is the mToken method. This method is a method of sending a special numeric code via SMS to the Mobile phone of a user who wants to make a financial transaction. Unlike the authentication method on the BTN Mobile application, the Livin' by Mandiri application uses a very common authentication method, namely the PIN (Personal Identification Number) method. This research was conducted to analyze comparisons related to the efficiency of the authentication method used in the BTN Mobile and Livin' by Mandiri applications using scenario testing. In addition, a comparative analysis of user experience was also carried out using the User Experience Questionnaire (UEQ) for both applications. In the data collection process, scenario testing was carried out with 11 participants and questionnaires were distributed to 52 participants. From the analysis process carried out, it was found that the Livin' by Mandiri application was more efficient and faster than the BTN Mobile application. In addition, the Livin' by Mandiri application also gives a better impression regarding the user experience, especially on the novelty aspect compared to the BTN Mobile application.

Abstract

Omah Kweni Homestay is a homestay accommodation located in the Bantul area of Yogyakarta city, which is a tourist city and can be a business opportunity in the hospitality industry. The homestay faces operational problems that are still conventionally managed, such as using a notebook that results in unreliable data storage, and the creation of reservation and warehouse reports takes a long time. To address these problems, a proposed solution is to develop a management information system that can assist in homestay management. The system development targets receptionists, roomboys, marketers, and managers. The Waterfall development method is used in this study because it is suitable for the homestay's parallel business processes where homestay requirements do not change. The use of the Waterfall development method is carried out in 4 stages. The needs analysis phase produces 6 business process models, 11 system features, 36 functional requirements and 1 non-functional system requirements, and 9 use cases and use case scenarios. The system design stage produces 9 Sequence Diagrams, 8 Class Diagrams consisting of class controllers and class models, 1 Physical Data Model, and 7 Wireframes. The system implementation stage results in the implementation of the design in the previous stage. The system testing phase using the black-box testing method produced 15 test cases and compatibility testing using the SortSite 6 Trial application with the results of 8 minor issues, User Acceptance Testing produced a percentage index of 90% for receptionists, 91.42% for marketing, 92.5% for Roomboy, and 97.14% for manager. The results of the user acceptance test show that all users agree with the development of the information system being developed.
