IMPLEMENTASI CONVOLUTIONAL NEURAL NETWORK DENGAN PRE-TRAINED MODEL MOBILENETV2 UNTUK DETEKSI KOLESTEROL

2024-07-22T12:18:13+07:00

One of the main risks for heart disease and stroke is cholesterol. 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.

Indonesia has diversity and natural wealth that attracts tourism in Indonesia. 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.

PENANGANAN MISSING VALUES DAN PREDIKSI DATA TIMBUNAN SAMPAH BERBASIS MACHINE LEARNING

2024-07-10T13:52:50+07:00

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.

PENERAPAN METODE ROTOSCOPING DAN FRAME ELIMINATION PADA ANIMASI 2D TARI ZAPIN

2024-07-10T13:52:51+07:00

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.
