Abstract

As an invasive and poisonous plant, Lantana has become a pest in the agricultural world. Still, on the other hand, it becomes an ornamental plant with different positive potentials. Lantana flower datasets are not yet widely available for open image classification research, given that the research needs are still broad in remote sensing. This study aims to provide a model with classifier accuracy that outperforms similar studies and Lantana datasets for classification needs using several algorithms that can be run on small source computers. This study used five types of lantana colors, red, white, yellow, purple, and orange, as the primary dataset, which had 411 instances. VGG16 assisted feature extraction in preparing datasets for the data training using three classifiers: decision tree, AdaBoost, and k-NN. 2-fold cross-validation, 5-fold cross-validation, and a self-organizing map are used to help validate each process. The experiment to measure the classifier's performance resulted in a good figure of 99.8% accuracy for 2-fold cross-validation, 100% for 5-fold cross-validation, and a primary dataset of lantana interest that can be accessed freely on the IEEE Data port. This study outperformed other related studies in terms of classifier accuracy.

Abstract

Malaka Regency is one of the regencies that is often affected by floods every year. The losses caused by floods include, cutting off access to an area and damage to houses and furniture in the house, so that people have to evacuate to other areas or to higher ground. Incidents like this show that these houses have not been able to respond to floods that occur, including Fahiluka Village in Malaka Tengah District, Malaka Regency. The characteristic of Malaka Regency settlements is traditional houses in the form of stages with wooden walls and thatched roofs. Traditional stilt houses are also included in flood disaster response housing, but stilt houses have almost disappeared due to modern houses that are built directly in contact with the ground. This study aims to design a flood-responsive building model by utilizing modern building materials but still adhering to local wisdom. The results of the calculation and modeling of the flood that will occur with a return period of 25 years, obtained a maximum flood height of 2.5 meters. Building materials use reinforced concrete construction on the elements of the building structure and the shape of the building resembles a local building model and the function of the building space is adjusted to the needs of the community, the area of ​​the house designed is 54 m2. The design of the building with a stilt house model is expected to be one of the solutions in minimizing losses due to the overflow of the flood community that cannot be avoided in the Fahiluka village area.

Abstract

This research aims to determine the important features including symptoms and risk factors for dengue diagnosis. This study’s dataset was obtained from medical records collected from two hospitals in Indonesia from patients with dengue and nondengue diseases. Four feature selection methods including feature importance, recursive feature elimination, correlation matrix and KBest were leveraged to determine significant features. Feature importance employed a tree-based classifier to derive the importance scores of the features. Recursive feature elimination employed a machine learning classifier to choose the most important features from the given dataset. Correlation matrix was employed to select the best features because it has the ability to use the correlation between each feature with the target. Univariate feature selection – Kbest has the ability to choose the best features based on univariate statistical tests. Important features were also gathered from fifteen Indonesian medical doctors to confirm the results. We used six machine learning techniques for dengue prediction. The random forest classifier yields the highest accuracy for the best combination of features with the accuracy of 0.93 (LR: 0.90 (0.04), KNN: 0.89 (0.04), XGBoost: 0.91 (0.03), RF: 0.93 (0.04), NB: 0.88 (0.09), SVM: 0.89 (0.04)) and precision of 0.90 (LR: 0.86 (0.22), KNN: 0.67 (0.14), XGBoost: 0.77 (0.13), RF: 0.90 (0.13), NB: 0.66 (0.20), SVM: 0.66 (0.18)). This study shows the significant features for dengue diagnosis including fever, fever duration, headache, muscle and joint pain, nausea, vomiting, abdominal pain, shivering, malaise, loss of appetite, shortness of breath, rash, bleeding nose, bitter mouth, temperature and age. This knowledge is pivotal to educate society to seek medical advice when dengue symptoms appear to avoid severe conditions. Arthralgia/joint pain and myalgia/muscle pain are the most significant features for the dengue prediction. This knowledge is important for medical doctors as a starting point for clinical dengue diagnosis.

Abstract

Tanah merupakan media sebagai tempat tumbuhnya tanaman. Tanah yang sehat menyediakan nutrisi penting di dalamnya. Komponen tanah yang terdiri dari bahan padatan, air, dan udara merupkan sumber daya alam yang sangat memengaruhi kehidupan. Fungsi utama tanah bagi tanaman adalah sebagai media untuk pertumbuhan dan berproduksi tanaman. Kemampuan tanah sebagai media tumbuh akan optimal jika didukung oleh sifat fisika, kimia dan biologi yang baik, biasanya menunjukkan tingkat kesuburan tanah. Penilaian kesuburan tanah secara komprehensif dapat dilakukan berdasarkan indikkator-indikator kesuburan tanah yang terdiri dari sifat fisik, kimia dan biologi tanah. Namun belum terdapat standar tetap dalam menilai kesuburan tanah secara komperehensif, dan masyarakat yang belum mengetahui dan memahami indikator kesuburan tanah. Oleh karena itu dibutuhkan suatu Sistem Pendukung Keputusan (SPK) untuk membantuyang dapat melakukan penilaian kesuburan tanah . Tujuan penelitian ini menghasilkan sebuah sistem pendukung keputusan yang dapat membantu masyarakat untuk menentukan kesuburan tanah. Metode penelitian yang digunakan dalam menentukan kesuburan tanah adalah Simple Additive Weighting (SAW). Hasil dari penelitian ini menunjukkan bahwa metode Simple Additive Weighting (SAW) sangat efektif dalam menentukan kesuburan tanah serta dapat membantu masyarakat khususnya yang berkecimpung di bidang pertanian untuk menilai apakah tanah yang digunakan tersebut dalam kondisi baik atau tidaknya dengan cara yang mudah dan cepat serta memperoleh status kesuburan tanah suatu daerah berdasarkan indikator kesuburan tanah yang telah ditentukan berdasarkan kriteria yang tersedia.

Abstract

This study aims to understand the public opinion in Indonesia regarding the existence of online loans. Online loans are a type of banking service through technology known as the Financial Technology (FinTech) Industry. According to a report by the Financial Services Authority, in August 2023, more than 13.37 million accounts were using this service. Online loan services are considered to provide convenience and comfort for consumers. However, many harmful cases have emerged, such as extremely high interest rates and aggressive debt collection practices that have caused public concern. Therefore, a sentiment analysis is conducted to understand public opinions, which can serve as a reference for online loan service providers and operators. By using 11,288 Indonesian-language tweets, the public opinion on online loans is analyzed. The study employs two sentiment analysis methods: Naïve Bayes and K-Nearest Neighbor. The results of the study show that the sentiment toward online loans is 62.29% negative, 33.19% neutral, and 5.52% positive. The results also indicate that the Naïve Bayes method has slightly higher accuracy (67%) compared to the K-Nearest Neighbor method (63%). It is hoped that this sentiment will have a positive impact on online loan service providers and operators.
