Abstract

Smartphone users in Indonesia are increasing every year so that many application development companies have created application-based non-cash payment services to make it easier for users to make non-cash payments. Many digital wallet applications have sprung up, including the Ovo and Dana application. The purpose of this research is to compare 2 digital wallet applications that have almost the same business processes and characteristics in the experience of using the two digital wallet applications. This study provides a comparison of user experience analysis based on scenario testing with parameters of time per completed task, error during task performance, number of clicks during task completion and task success rate as well as user experiance questionnaire (UEQ) parameters which have six aspects of assessment, including attractiveness, perspicuity, efficiency, dependability, stimulation and novelty. Scenario testing was carried out on 10 respondents who had never previously used these two applications and the UEQ questionnaire was distributed to 20 respondents. The results of the test assignment or scenario show that the respondent's success is quite high even though the previous respondent has never used these two applications. Funding applications have a higher value in two parameters, namely the error during task performance and number of clicks during task completion and the Ovo application is better in the time per completed task parameter and the task success rate parameter aspects of both applications have the same good value. The results of the UEQ questionnaire show that respondents have a positive tendency towards the two digital wallet applications where the fund application has a better value in four aspects of the measurement scale, namely attractiveness, perspicuity, dependability and novelty. Meanwhile, the ovo application has a better value in terms of efficiency and stimulation.

Abstract

Since the Jakarta mass rapid transit (MRT) was operated, there have been various opinions from the public regarding facilities and services of the Jakarta MRT which have been conveyed through social media such as Twitter, Instagram, TikTok, and YouTube. In writing opinions on social media, errors are often found such as slang words, abbreviated words, and typographical errors which can complicate the classification process. Based on that thing, this research will use word normalization with a dictionary of slang words and abbreviations and also use word normalization with Peter Norvig. Opinions that have been conveyed by the public must be analyzed properly in order to produce useful information for PT MRT Jakarta. In conducting sentiment analysis, a classification method is needed and the classification method to be used is the Naive Bayes method. Testing in this research used 5-fold and for each fold 200 training data and 50 test data were used. Based on the test results, it can be concluded that the classification is better to use word normalization because the existence of word normalization can equate two words that have the same meaning so that it can increase the weight of the words. The 5-fold average evaluation results of the Naive Bayes classification with word normalization using a dictionary of slang words and abbreviations and also word normalization using Peter Norvig yielded 0.903 for precision, 0.944 for recall, 0.922 for f-measure, and 0.903 for accuracy.

Abstract

The potential for disasters in Ponorogo Regency is handled by the Badan Penanggulangan Bencana Daerah (BPBD). Recording of post-disaster reports at BPBD Ponorogo Regency is still done manually using Microsoft Excel and Microsoft Power Point for disaster publications to the public through the WhatsApp application. So we need a website-based system to facilitate reporting and publication of reports to the public as a form of data transparency. TRC (Quick Reaction Team) can record reports directly on the system. After being reviewed by PUSDALOPS and verified by the Kepala Pelaksana, the results of report verification can be accessed by the public via the website and using a GIS (Geographic Information System) to facilitate accurate reading of data by the public by directly looking at the affected areas on the map. This study uses the Waterfall method, data collection for needs analysis is carried out by interviewing one of the BPBD employees of Ponorogo Regency. The requirements analysis resulted in 23 functionalities which were implemented using the PHP programming language and the Laravel Framework, Leafleat js as a library for displaying maps, and the mySQL database. The implementation results tested using white-box, black-box testing, usability testing, Pearson product testing, split half testing and testing matrix model testing. From these tests, it was obtained valid results for white-box testing, one test was invalid from a total of 23 test-cases in black-box testing. For usability testing, a score of 62.5 was obtained or it was in the 'good' category. Meanwhile, for the feature validation test, there are 4 valid features, 6 invalid features and the rest cannot be calculated because there is a costant variable. The accuracy of GIS (Geographic Information System) using a test matrix model, the value is 80%.

Abstract

Watermelon in Latin from Citrullus Lanatus Tunb is one of the vines that is developing very rapidly in Indonesia, besides that Indonesia is also the largest producer of watermelons in the world. It was found that the interest of many people is fond of watermelon. It can be seen that watermelon yield data in 2014 was 653,974. The type of watermelon that is often in demand is watermelon which has no seeds, which has a soft texture, does not contain too much water, and has a paler flesh than the seeded watermelon. This research carried out feature extraction on the texture of watermelon rind using the Gray Level Co-Occurrence Matrix (GLCM) method, then using the Support Vector Machine (SVM) to classify the sweetness or unsweetness of watermelon fruit without seeds with a distance of 10-11 cm. This research requires a camera on the system to be able to take images for detection and class classification can be done. If the system can detect the sweetness of watermelon without seeds, it will be displayed on 16x2 LCD. The GLCM features used in this study are correlation, contrast, homogeneity, energy, and dissimilarity. Tests conducted using the SVM kernel, namely linear, RBF, and polynomial kernels. To get the best d and θ values ​​in this study, several trials were carried out with values ​​of d=1,2 and θ=0⁰, 45⁰, 90⁰, 135⁰. The best d and θ values ​​after testing the detection of the sweetness of watermelon without seeds were d=2 and θ=45⁰ with an accuracy of 95%. Hardware integration testing is carried out from various sides of the image taking, namely from the front, back, and top. Obtained the best accuracy in testing the integration of hardware using the best d and θ values, which is 80% on the back side using a polynomial kernel. In testing the computation time of the system with a value of d=2 and θ=45⁰, the best kernel was obtained, namely the polynomial kernel to detect the sweetness of watermelon without seeds, which took 13.13 seconds.
