Cholesterol is a type of fat produced primarily by the liver and absorbed in small amounts from food. The ideal cholesterol level in the human body should be less than 200 mg/dl. One way to check cholesterol levels is through a blood sugar test that requires the patient to fast for 10 to 12 hours. Given the dangers posed by high cholesterol levels, there is a need for an early, practical screening method to detect high cholesterol levels in the human body. Iridology is an analysis of the iris of the eye to detect health conditions and show the relationship between iris patterns and cholesterol levels. The iris has its own uniqueness because it can record the condition of all organs, body structures, and psychological states. Therefore, iridology can be an alternative medical analysis. This study proposes the use of a convolutional neural network algorithm using a pre-trained MobileNetV2 model. The iris image dataset used consists of 200 images classified into two classes: normal eye images and cholesterol eye images. The results of the study show that the proposed model can achieve an accuracy of 95%. These results indicate that this model has great potential as a practical and cost-effective tool for detecting cholesterol. Further research is needed with larger datasets to improve accuracy and validity.</p> Indah Sri Lestari, Jumadi Jumadi, Nur Lukman ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4732 Mon, 08 Jul 2024 19:30:16 +0700 PEMANFAATAN STFT DAN CNN DALAM PENGOLAHAN DATA SUARA UNTUK MENGKLASIFIKASIKAN SUARA BATUK https://jurnal.univrab.ac.id/index.php/rabit/article/view/4729 <p><em>This research aims to develop an automatic cough sound evaluation system to improve the accuracy of respiratory disease diagnosis. In this study, the Short-Time Fourier Transform (STFT) and Convolutional Neural Network (CNN) methods were used to classify cough sounds into dry and wet coughs. The Naïve Bayes model was then used to identify respiratory diseases based on the cough classification results. Testing was conducted using the available cough sound dataset, resulting in a cough classification accuracy of 82% and a respiratory disease identification accuracy using Naïve Bayes of 71.43%. The evaluation results indicate that the developed system can accurately classify cough types and identify diseases. This system has the potential to enhance the prevention and management of respiratory diseases in resource-limited areas and can be a significant tool in medical practice for faster and more accurate diagnoses. Furthermore, this research opens opportunities for further development in disease detection and diagnosis technology through sound analysis, providing wide-ranging benefits for society and the healthcare sector.</em></p> Indri Nurfiani, Jumadi Jumadi, Muhammad Deden Firdaus ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4729 Mon, 08 Jul 2024 19:38:34 +0700 ANALISA DAN DESAIN KONTEN INSTAGRAM YANG MENARIK DAN BERDAMPAK POSITIF PADA INTERAKSI PENGGUNA https://jurnal.univrab.ac.id/index.php/rabit/article/view/4687 <p><em>As one of the most popular social media platforms today, Instagram has more than one billion monthly active users. This is a great opportunity for users to interact with each other, share content, and build rapport. However, to achieve this, the right strategy is needed to create interesting content according to user interests. In line with the aim of this research, to obtain interesting content that has a positive impact on user interaction, researchers use the Design Thinking method which involves users and stakeholders in Instagram accounts. This research was conducted by including three content designs that provide the best insight from more than sixty Instagram content designs posted on accounts in the period 5 June to 6 September 2023 on the Graphic Multimedia Engineering Technology (TRMG) study account @trmg_unisbank which was used as an object. From the analysis and design of Instagram content, it managed to reach 20,275 followers with 80 accounts and 20,195 non-follower accounts. This means that attractive content design can have a positive impact on user engagement. This content is built by exploring the target audience, understanding user interests, using images and design, including interesting captions and relevant hashtags, and conveying useful information (education).</em></p> Sri Mulyani, Purwatiningtyas Purwatiningtyas, Yunus Anis ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4687 Mon, 08 Jul 2024 20:50:24 +0700 SISTEM PAKAR DIAGNOSA POST TRAUMATIC STRESS DISORDER DENGAN METODE FORWARD CHAINING https://jurnal.univrab.ac.id/index.php/rabit/article/view/4607 <p><em>Post traumatic stress disorder</em> (PTSD) is a disorder experienced by someone due to surprising, scary, or dangerous events they had. Unfortunately, there is minimal knowledge about this disorder among Indonesian people so that many of them do not know what symptoms they have experienced and the effects from the disorder. The aim of this study is to build an expert system for early diagnose of this PTSD. Forward chaining method is utilized within the expert system to collect the symptoms experienced by users, processing them based on knowledge rules until a decision or conclusion achieved. The expert system was developed following the Expert System Development Life Cycle (ESDLC) and the built system usability level was measured by using the USE questionnaire. The system was then tested together with an expert that showed the agreement level of the system with the expert. From the Usability level measurement, the system got a score of 86.67% which show the system is useful for early diagnose of PTSD. Hopefully, this expert system could become a solution in giving ease of accessibility for people to get an early diagnose result of PTSD.</p> Mochamad Rizky Zaldi, Seng Hansun ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4607 Mon, 08 Jul 2024 20:58:52 +0700 ANALISIS FAKTOR YANG MEMPENGARUHI PEMILIHAN GUBERNUR DAERAH KHUSUS JAKARTA MENGGUNAKAN ALGORITMA NAIVE BAYES DAN REGRESI LOGISTIK https://jurnal.univrab.ac.id/index.php/rabit/article/view/4778 <p><em>The election of the Governor and Deputy Governor of the Special Region of Jakarta (DKJ) in 2024 involves the community in determining leaders for the 2024-2029 period. This research analyzes the factors influencing voter decisions using the Naive Bayes algorithm and Logistic Regression. Survey data was collected via a Google Form questionnaire from Jakarta residents aged 17-71. The analysis process involves several stages: problem identification, literature study, data collection, preprocessing, and dividing the data into training and test data. The Naive Bayes algorithm is used to predict classification parameters based on a candidate's education, popularity, and track record, while Logistic Regression predicts factors that influence voter decisions. Naive Bayes shows high accuracy with advantages in speed and processing large data, while Logistic Regression shows strength in binary and multinomial classification analysis. The research results show that the track record factor significantly influences voter decisions. Naive Bayes prediction accuracy reached 85.00% and Logistic Regression 80.00%.</em> &nbsp;<em>The analysis results also reveal that the candidate's popularity and education factors rationally influence voter decisions, although not as strong as the track record. In addition, using these two algorithms provides a comprehensive understanding of voter behavior in Jakarta. Based on these results, governor and deputy governor candidates should also focus on improving their track record and popularity to increase their chances of being elected. </em></p> Yoga Nanda Khoiril Umat, Dhiaz Rusyda Nafsyi, Diana Kusumaningsih, Lukman Hakim ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4778 Mon, 08 Jul 2024 21:10:05 +0700 PENERAPAN JARINGAN SARAF TIRUAN DENGAN ALGORITMA PERCEPTRON PADA DETEKSI PENYAKIT BAWANG MERAH https://jurnal.univrab.ac.id/index.php/rabit/article/view/4800 <p>Penelitian ini difokuskan pada kemajuan sistem deteksi penyakit bawang merah (Allium ascalonicum) menggunakan Jaringan Saraf Tiruan (JST) dengan Algoritma Perceptron.

Tourism is one of the industries that provides the highest foreign exchange for the country because it has a positive impact. However, the existence of COVID-19 has resulted in a decrease in the number of visits due to restrictions on foreign tourists. From January to November 2021, there was a drastic decrease of 61.82% in the number of foreign tourist visits compared to the same period in 2020. In addition to COVID-19, as well as support in building facilities that support the increase in the number of foreign tourists. From these conditions, predictions are needed that are used as a basis for planning and helping decision making. The purpose of this study is to develop a more accurate prediction model in similar studies using the same data in predicting foreign tourist arrivals in Indonesia through air entrances using the XGBoost, Random Forest, and Catboost methods by focusing on the accuracy evaluation results metrics RMSE, MAE, and MAPE and making predictions for the next 12 months. The dataset used is taken from the Central Statistics Agency (BPS), namely data on foreign tourist arrivals based on the arrival entrance in the period January 2017 to November 2021. The data used are time series and non-stationary. From the research results, it can be seen based on the accuracy evaluation results that the XGBoost model of this study gets better accuracy evaluation results than the other two models by getting the results of the RMSE accuracy evaluation value of 671935.2, MAE 648139.1, and MAPE 20985.35. The XGBoost model is better with a smaller accuracy error value than the Random Forest model, Catboost, and similar research using the ARIMA method with an RMSE value of 779670.7, MAE 749030.4, and MAPE 23196.45.</em></p> Arya Prayuda, Irfan Pratama ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4787 Mon, 08 Jul 2024 21:22:50 +0700 PENANGANAN MISSING VALUES DAN PREDIKSI DATA TIMBUNAN SAMPAH BERBASIS MACHINE LEARNING https://jurnal.univrab.ac.id/index.php/rabit/article/view/4789 <p><em>The issue of increasing waste due to the growing population and human activities presents a serious challenge in waste management in Central Java. One of the main obstacles in waste prediction research is the prevalence of missing data, which can reduce the accuracy of predictive models. This study employs three methods to handle missing values: Mean Imputation, Interpolation, and KNN Imputer. Once the missing values are filled using these methods, the next step is to calculate the prediction values. The study utilizes three predictive models: Random Forest, Gradient Boosting, and KNN. The results indicate that with Mean Imputation, the Random Forest model shows the best performance with an RMSE of 0.349. When using Interpolation for missing values, the Gradient Boosting model becomes the best choice with an RMSE of 0.543. Meanwhile, with KNN Imputer, the Gradient Boosting model again performs the best with an RMSE of 0.188. Based on this research, the most effective approach is using KNN Imputer for handling missing values in conjunction with the Gradient Boosting model. This combination provides the lowest RMSE for similar datasets.</em></p> Anisa Widianti, Irfan Pratama ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4789 Mon, 08 Jul 2024 21:30:35 +0700 PENERAPAN METODE ROTOSCOPING DAN FRAME ELIMINATION PADA ANIMASI 2D TARI ZAPIN https://jurnal.univrab.ac.id/index.php/rabit/article/view/4791 <p><em>The growth of the animation industry in Indonesia is predicted to continue to grow. This can be seen from the development of animation in Indonesia, which is dominated by 2-dimensional and 3-dimensional animation in recent years, as well as being marked by the large number of animators from Indonesia who are successful on the international stage. Generally, animation is applied to character movements, whether simple movements such as walking, to complex movements such as fighting. In its application, various methods can be used as long as they can create animated movements that match the original movements. Generally this is done successfully because in complex movements, the speed of the movement seems to obscure the animation details of the movement. However, this does not apply to one type of movement that is very rarely used in animation, this movement is dancing. The reason why dance movements are rarely animated is because dance is a series of movements that have low speed, so that the details in each change in movement in one dance can produce hundreds or even thousands of frames when converted into animation. Visualizing dance art with animated visuals is not an easy thing, because there are many frames that have to be created so that the dance looks natural. Moreover, using animation techniques such as frame by frame and cutout, of course, actually increases the processing time and quantity of images produced. Actually, apart from frame by frame and cutout, there are still other animation techniques that can be applied to overcome the problem of many frames in dance movements. One solution is to visualize dance in animated form. Namely the rotoscoping technique which can bridge dance with animation. This rotoscoping imitates every change in movement in dance, and converts it into a frame. However, if you only use this technique, the resulting image will still be too large, so one more technique needs to be added, namely frame elimination. For this reason, the author wants to apply the rotoscoping technique in making Zapin dance animations. To find out whether dance art can be visualized well using rotoscoping and Frame Elimination techniques.</em></p> Rokhmatulloh Batik Firmansyah, Dhimas Adi Saputra, Chyntia Dianly Lukman, Qashdan Aqil Al-Bajili, Jimmy Cristian ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4791 Mon, 08 Jul 2024 21:42:38 +0700 PENERAPAN TEKNIK PENETRATION TESTING TERHADAP CROSS SITE SCRIPTING (XSS) DALAM PENGEMBANGAN WEBSITE https://jurnal.univrab.ac.id/index.php/rabit/article/view/4822 <p><em>The increasing use of websites in various aspects of daily life has led to an urgent need to ensure the security of the information presented. One of the significant threats in website security is Cross-Site Scripting (XSS), where an attacker inserts malicious code into a web page to be executed by the user. This research aims to apply penetration testing techniques as a method to detect and resolve XSS vulnerabilities in website development. The research was conducted through three stages: installation of software to support penetration testing, execution of penetration testing using OWASP ZAP to identify vulnerabilities, and evaluation and implementation of solutions to address the vulnerabilities found. The results show that the implementation of the htmlspecialchars function in PHP is effective in preventing the execution of malicious scripts, thereby reducing the risk of XSS attacks. In addition, penetration testing techniques proved to be an effective method in identifying and mitigating security risks in web applications.

The manual data management that residents still apply creates difficulties in the process of searching and managing koloman data. This causes the time required to enter and search for information to be longer, and increases the risk of inaccuracies. Additionally, physical storage of information can also pose security and support issues, as information can be lost or damaged. As a result, data management becomes inefficient and people have difficulty finding the information they need quickly and accurately. To overcome these problems, this research proposes an innovative and sustainable solution for designing a web-based koloman data management application. This application is designed to facilitate centralized data processing, automate data input, and provide real-time access to information. Thus, it is hoped that this application can increase the accuracy, speed and transparency of koloman data management, as well as provide significant benefits for the community in managing koloman data more effectively and efficiently. The application of web-based technology also opens up opportunities to increase the capacity of local communities in utilizing information technology.</em></p> <p><em>&nbsp;</em></p> Fauzan Prasetyo Eka Putra, Siti Ririn Sutarsih, Sofiyulloh Sofiyulloh, Putra Permana, Muhammad Umar Mansyur ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4840 Tue, 09 Jul 2024 06:32:13 +0700 PENGGUNAAN ALGORITMA GEOSHASHING DALAM PENCARIAN LETAK INFORMASI GEOGRAFIS PENGGANTI KOOORDINAT LATITUDE DAN LONGITUDE https://jurnal.univrab.ac.id/index.php/rabit/article/view/4848 <p>Dalam era digital saat pencarian data geografis menjadi semakin penting dalam aplikasi lokasi, termasuk pemetaan, navigasi, dan analisis lingkungan tempat dalam suatu lokasi. algoritma geohashing menawarkan pendekatan yang efisien untuk pengkodekan dan menyimpan data geografis dalam format string,String ini menggunakan alfanumerik yang dihasilkan oleh geohashing dari angka dan huruf dalam pencarian titik lokasi dengan koordinat, hal ini juga dapat menawarkan lapisan akses dari data lokasi yang sensitif.

Recording vehicle license plates requires the application of information technology so that parking service administration is more efficient and free from recording errors. Information technology offers the application of OCR (Optical Character Recognition) methods to help the process of recording characters found on vehicle license plates. OCR has many techniques that can help the character recognition process, starting from the initial image capture process to the recognition stage. The initial image stage after being captured is to perform the initial image processing process by converting the image, determining the vehicle license plate area in the vehicle image, performing character labeling and segmentation on the plate image, and performing character recognition. The approach to character recognition on vehicle license plates that will be used is Hough Transform for determining the vehicle license plate area, character labeling and segmentation with Connected Component Labeling, and Template Matching as a character recognition method. The vehicle license plate character recognition model was tested with a scenario of 25 images captured directly from the parking lot. The test results produced Hough Transform and Connected Component Labeling could determine the vehicle license plate area and perform character labeling and segmentation on the vehicle license plate. Whereas in the template matching stage, the character recognition accuracy on 25 vehicle license plates was 94%. Other findings in this study are that the lighting conditions of the image environment, the number of images that become the database, and the condition of the paint of motor vehicle license plates can improve accuracy.</em></p> Fredicia Fredicia, Gardyan Santoso ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.univrab.ac.id/index.php/rabit/article/view/4636 Wed, 10 Jul 2024 11:51:33 +0700 PENERAPAN FUZZY ASSOCIATIVE MEMORY UNTUK MENGUKUR TINGKAT KEPUASAN PELANGGAN TERHADAP PELAYANAN PADA TOKO KOPIMA https://jurnal.univrab.ac.id/index.php/rabit/article/view/4773 <p><em>One of the advantages of information technology in the field of business is that it can help in measuring the level of customer satisfaction.
