Abstract

Salah satu permasalahan yang ada di Gardu Induk Nagan Raya F adalah gangguan hubung singkat sering terjadi pada jaringan 20 kV yaitu antara fasa (3 fasa atau 2 fasa) atau gangguan hubung singkat fasa ke tanah (2 fasa atau 1 fasa ketanah), jika koordinasi proteksi kurang baik dapat menyebabkan pemadaman yang meluas yang disebut blackout. Selain itu apabila terjadi gangguan pada penyulang NG-02  maka peralatan pengaman incoming transformator daya 2 juga ikut bekerja. Hal ini perlu dilakukan penelitian untuk menganalisa penyebab terjadinya kurang baiknya koordinasi antara peralatan pengaman. Dari lokasi gangguan juga mempengaruhi selisih waktu kerja (gradding time) bekerjanya rele. Semakin jauh jarak lokasi gangguan, maka semakin besar selisih waktu kerja rele di incoming 20 kV. Hal ini bertujuan memberi kesempatan pada rele di outgoing NG-02 untuk bekerja terlebih dahulu sebagai pengaman utama apabila terjadi gangguan hubung singkat di jaringan dan rele di incoming bekerja sebagai cadangan apabila rele di outgoing tidak bekerja. Rele OCR pada sisi incoming maupun outgoing 20 kV, sudah berkoordinasi dengan baik. settingan pada sisi Incoming ialah sebesar 1,03 A dengan arus gangguan pada sisi primer sebesar 2078,4 A dan rasio CT yang digunakan 2000/1. Waktu trip jika gangguan pada jarak 5% ialah 1,35 detik. Settingan pada sisi Outgoing ialah sebesar 6 A dengan arus gangguan pada sisi primer sebesar 960 A dan rasio CT yang digunakan ialah 800/5. Waktu trip jika gangguan pada jarak 5% ialah 0,73 detik.

Abstract

The present study investigates the variables believed to relate to and affect Japanese language students’ willingness to communicate in Japanese in online learning situations. This study was a quantitative study that used questionnaire data as the main data distributed through the Google Form platform. A total of 81 Japanese language students from three universities participated. The findings showed that anxiety negatively correlated with willingness to communicate inside the classroom. Meanwhile, self-rating and virtual intercultural experiences positively correlated with willingness to communicate inside the classroom, outside the classroom, and in digital settings. The regression analysis showed that language anxiety, self-rating, and virtual intercultural experiences variables had a minor effect on willingness to communicate inside the classroom (19%) and digital setting (22.5 %). The results of this study indicate that besides the factors of anxiety, self-rating, and virtual intercultural experience, other variables are considered to be more contributing to how Japanese language students have the will to communicate in the target language.

Abstract

Ketapang Regency is one of the areas in West Kalimantan that is prone to drought. Drought can trigger forest and land fires. In this research, the Keetch-Byram Drought Index (KBDI) method was used to determine the level of drought in Ketapang Regency. The KBDI method relies on annual rainfall accumulation, daily rainfall, and maximum air temperature. The KBDI values obtained were correlated with the number of hotspots using Pearson correlation. This research was conducted throughout 2018-2022. Based on the monthly average KBDI value, the highest drought in Ketapang Regency occurred in August and September, while the lowest drought occurred in December and January. In terms of the annual average, the highest drought occurred in 2019. During the ENSO phenomenon in 2019, the El Niño phase experienced higher drought than the La Niña phase and normal years. In the El Niño phase, drought levels reach high to extreme categories. The correlation value between annual KBDI and the number of hotspots is 0.88, indicating a solid relationship. An increase in the KBDI value will be followed by an increasing number of hotspots.

Abstract

Umatan wasathan is a way of forming the character of Muslims which represents various differences in beliefs between religions. Umatan wasathan has an important role in maintaining harmony, peace and tranquility so that a harmonious society can be created amidst differences. In the process of its implementation, the Umatan wasathan makes Muslims not to be excessive, to be in a middle position, not extreme right or left, but to have a moderate character that adorns the personality of every Muslim. This research discusses the Umatan wasathan in the Al-Qur'an surah al-Baqarah verse 143. This research uses a qualitative research type of literature study which is presented descriptively-analytically using Roland Barthes' semiotic approach. The results of the research show that the Wasathan Ummah is a people who have a moderate character which is reflected in the ability to act fairly, be balanced, and be able to implement beneficial values. Muslims are asked to be able to combine two things, namely, piety in the afterlife and worldly life. This research recommends that future researchers examine the future of Indonesian life amidst diversity and religiousity.

Abstract

Breast cancer is one of the most common causes of death worldwide. Data mining can be utilized to detect breast cancer, where information is extracted from data to provide valuable insights. Clustering of breast cancer is conducted to assist medical professionals in grouping the characteristics of each cancer type. However, multicollinearity in breast cancer data can impact clustering results. To address this issue, dimensionality reduction through Principal Component Analysis (PCA) is employed. PCA can effectively handle multicollinearity issues and enhance computational efficiency. Additionally, the K-Means method has limitations in determining the optimal number of clusters. Therefore, the Gap Statistic method is employed to find the optimal K value suitable for breast cancer data. This study compares the evaluation results of the K-Means clustering model, the combined PCA-KMeans clustering model, and the combined PCA-GapStatistic-KMeans clustering model. The findings indicate that the evaluation results for the K-Means model with PCA dimensionality reduction and optimal Gap Statistic K are superior to the K-Means model without dimensionality reduction. The Gap Statistic suggests 2 clusters as the optimal number, with an evaluation result of 1.195513.

Abstract

Software Defect Prediction is crucial to ensure software quality. However, high-dimensional data presents significant challenges in predictive modelling, especially identifying the most relevant features to improve model performance. Therefore, efforts are needed to address these issues, and one is to apply feature selection methods. This study introduces a new approach by applying the Copeland ranking method, which aggregates feature weights from multi-wrapper methods, including Recursive Feature Elimination (RFE), Boruta, and Custom Grid Search, using 12 NASA MDP datasets. The study also applies Random Forest classification and evaluates the model using AUC and t-Test. In addition, this study also compares the accuracy and precision values produced by each method. The results consistently show that the Copeland ranking method produces superior results compared to other ranking methods. The average AUC value obtained from the Copeland ranking method is 0.7496, higher than the Majority ranking method with an average AUC of 0.7416 and the Optimal Rank ranking method with an average AUC of 0.7343. These findings confirm that applying the Copeland ranking method in wrapper-based feature selection can enhance classification performance in software defect prediction using Random Forest compared to other ranking methods. The strength of the Copeland method lies in its ability to integrate rankings from various feature selection approaches and identify relevant features. The findings of this research demonstrate the potential of the Copeland ranking method as a reliable tool for ranking features obtained from various wrapper-based feature selection techniques. The implementation of this approach contributes to improved software defect prediction and provides new insights for the development of ranking methods in the future

Abstract

DNA microarray is used to analyze gene expression on a large scale simultaneously and plays a critical role in cancer detection. The creation of a DNA microarray starts with RNA isolation from the sample, which is then converted into cDNA and scanned to generate gene expression data. However, the data generated through this process is highly dimensional, which can affect the performance of predictive models for cancer detection. Therefore, dimensionality reduction is required to reduce data complexity. This study aims to analyze the impact of applying Principal Component Analysis (PCA) for dimensionality reduction, Genetic Algorithm (GA) for feature selection, and their combination on microarray data classification using Support Vector Machine (SVM). The datasets used are microarray datasets, including breast cancer, ovarian cancer, and leukemia. The research methodology involves preprocessing, PCA for dimensionality reduction, GA for feature selection, data splitting, SVM classification, and evaluation. Based on the results, the application of PCA dimensionality reduction combined with GA feature selection and SVM classification achieved the best performance compared to other classifications. For the breast cancer dataset, the highest accuracy was 73.33%, recall 0.74, precision 0.75, and F1 score 0.73. For the ovarian cancer dataset, the highest accuracy was 98.68%, recall 0.98, precision 0.99, and F1 score 0.99. For the leukemia dataset, the highest accuracy was 95.45%, recall 0.94, precision 0.97, and F1 score 0.95. It can be concluded that combining PCA for dimensionality reduction with GA for feature selection in microarray classification can simplify the data and improve the accuracy of the SVM classification model. The implications of this study emphasize the effectiveness of applying PCA and GA methods in enhancing the classification performance of microarray data.
