Abstract

Tanaman pinang dapat tumbuh pada kelembapan tanah sekitar 60 - 80%, dengan pH tanah antara 4 – 8, dan suhu optimum 20 - 32℃. Tanaman pinang membutuhkan pasokan air dan pupuk dengan kadar yang sesuai dan pemberiannya dilakukan secara terjadwal untuk mendapatkan pertumbuhan yang optimal. Maka dari itu, dikembangkan sebuah sistem yang dapat mengambil keputusan durasi penyiraman dan pemupukan otomatis yang bekerja secara terjadwal. Penelitian ini menggunakan logika fuzzy mamdani yang diintegrasikan dengan Arduino Uno sebagai pengendali utama sistem. Sensor DHT11, capacitive soil moisture sensor, dan sensor pH tanah dijadikan parameter masukan fuzzy. Pengujian sistem dilakukan dengan jadwal penyiraman setiap hari pada pukul 08.00 dan 16.00, pemupukan jadwalkan setiap seminggu sekali pada pukul 10.00 menggunakan Real Time Clock (RTC). Sistem inferensi fuzzy yang dirancang telah berhasil mengatasi permasalahan yang ada. Hasil pengujian basis aturan fuzzy pada proses penyiraman didapatkan nilai akurasi sebesar 93% dan proses pemupukan diperoleh nilai akurasi sebesar 86%.

Abstract

OCTO Friends application was developed to allow customers to directly participate in banking product referral program, has not met expectations and targets. Only 10.6% of the 39,105 members actively provided referrals, and business conversion rate was only 10% of the target. This study aims to evaluate the application's usability and generate recommendations for interface design improvement. A mixed methods research approach was used, including quantitative research through user needs questionnaires and System Usability Scale (SUS), along with qualitative research through in-depth interviews and usability testing. Data collection through questionnaires involved 104 respondents, resulting in a list of user needs and SUS score of 66. The results showed that OCTO Friends is requires some improvements. In-depth interviews and usability testing for six main functions led to 46 interface design improvements, especially improvements in referral data input, follow-up referral, and incentive information functions as these are primary functions of referral application.

Abstract

Because credit cards are utilized so frequently, fraud appears to be a significant concern in the credit card industry. It is challenging to quantify the effects of misrepresentation. Globally, credit card fraud has cost institutions and consumers billions of dollars. Despite the existence of numerous anti-fraud mechanisms, fraudsters continue to seek out novel methods and strategies to commit fraud. An additional challenge in the estimation of credit card fraud loss is that the magnitude of unreported or undetected forgeries cannot be determined, only losses associated with those frauds that have been detected can be measured. Implementing effective fraud detection algorithms through the utilization of machine-learning techniques is crucial in order to mitigate these losses and provide support to fraud investigators. This paper presents a machine learning-based method for the detection of credit card fraud. Three methodologies are implemented on the raw and pre-processed data. Python is used to implement the work. By comparing the accuracy-based performance evaluations of k-nearest neighbor and logistic regression with Random Forest, it is determined that the former exhibits superior performance.

Abstract

Diabetes merupakan penyakit metabolik dengan gejala hiperglikemia akibat gangguan sekresi insulin dan aksi insulin. Diabetes gestasional adalah gangguan toleransi glukosa pada wanita hamil. Saat kehamilan, plasenta menghasilkan hormon baru seperti human placental lactogen (HPL), hormon estrogen, dan hormon peningkat resistensi insulin. Gejala diabetes gestasional tidak selalu mudah dikenali, dan seringkali penderitanya mengalami gejala awal secara tidak sadar. Penelitian ini bertujuan untuk membandingkan performa dua algoritma yaitu K-NN dan Naïve Bayes dengan Feature Selection dalam mengklasifikasikan penderita diabetes gestasional. Hasil error terendah dari feature selection dengan iterasi K=4, memperoleh MAE 0.317, MSE 0.142, dan RMSE 0.377. Hasil akurasi pada model KNN dengan K=5 , tanpa Feature Selection sebesar 80% dan K-NN dengan Feature Selection sebesar 77%. Sementara itu, Naïve Bayes tanpa Feature Selection sebesar 77% dan Naïve Bayes dengan Feature Selection sebesar 80%. Dari hasil tersebut K-NN tanpa Feature Selection dan Naïve Bayes dengan Feature Selection mendapatkan hasil yang lebih baik.

This study investigates the effectiveness of several machine learning algorithms in reliably classifying Iris flower species by utilizing a dataset that includes crucial morphological attributes such as sepal length, sepal width, petal length, and petal width. The algorithms under consideration are Decision Tree, Random Forest, Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and XGBoost. Every algorithm has its own distinct methodology for classification, where Decision Trees offer clear interpretability and Random Forest and XGBoost offer strong and complex ensemble techniques. The primary aim of this study is to assess and contrast different algorithms, considering not only their classification accuracy but also significant performance metrics including precision, recall, F1-score, ROC AUC, and specificity. This research provides valuable insights into the capabilities and constraints of each methodology when implemented on a meticulously organized and defined botanical dataset. It is expected that the results of this study will contribute significantly to the fields of artificial intelligence and botanical taxonomy, highlighting the capacity of these methods to accurately identify and categorize plant species.

Abstract

In the realm of obstetrics, the evaluation of fetal health remains a paramount yet challenging endeavor. Traditional approaches, such as electronic fetal monitoring (EFM), despite their widespread adoption, continue to grapple with uncertainties regarding their impact on neonatal outcomes and the reduction of emergency cesarean deliveries. This ambiguity is compounded by a prevailing confusion within the obstetric community about interpreting fetal heart rate patterns, often leading to inconsistent and subjective assessments. Addressing these complexities, our study presents an innovative machine learning-based techniques for the comprehensive classification of fetal health using cardiotocogram (CTG) data, offering a more objective and nuanced alternative to conventional methods. The core of our proposed solution is a novel model employing a sophisticated ensemble of machine learning classifiers, including Multi-Support Vector Machine (Multi-SVM), Decision Tree, Random Forest with Hyperparameter Tuning, XGBoost, and Neural Networks. This model is unique in its application, processing datasets in four different forms: raw datasets, datasets processed with MinMaxScaler, datasets subjected to feature selection using SelectKBest, and a combination of MinMaxScaler processing and SelectKBest feature selection. Such meticulous preprocessing, encompassing normalization and feature selection, is pivotal in ensuring equitable contribution from each feature, thereby optimizing the model's learning process and predictive accuracy. The effectiveness of our model is rigorously evaluated using a dataset comprising 2126 individual records from CTG exams, classified by specialist obstetricians into three types: Normal, Suspect, and Pathological. These records are exhaustively analyzed using various metrics, including Accuracy, Precision, Recall, F1-Score, ROC AUC, and Confusion Matrix. Among the classifiers, XGBoost emerged as the most proficient, consistently outperforming others across multiple metrics. This indicates its superior ability to accurately identify and categorize the different states of fetal health. Our findings thus underscore the significant promise of machine learning in revolutionizing fetal health monitoring, offering a more reliable, objective, and comprehensive method for assessing fetal well-being, with profound implications for prenatal care and clinical decision-making.
