The extremely skewed data in artificial intelligence, machine learning, and data mining cases are often given misleading results. It is caused because machine learning algorithms are designated to work best with balanced data. However, we often meet with imbalanced data in the real situation. To handling imbalanced data issues, the most popular technique is resampling the dataset to modify the number of instances in the majority and minority classes into a standard balanced data. Many resampling techniques, oversampling, undersampling, or combined both of them, have been proposed and continue until now. Resampling techniques may increase or decrease the classifier performance. Comparative research on resampling methods in structured data has been widely carried out, but studies that compare resampling methods with unstructured data are very rarely conducted. That raises many questions, one of which is whether this method is applied to unstructured data such as text that has large dimensions and very diverse characters. To understand how different resampling techniques will affect the learning of classifiers for imbalanced data text, we perform an experimental analysis using various resampling methods with several classification algorithms to classify articles at the Indonesian Scientific Journal Database (ISJD). From this experiment, it is known resampling techniques on imbalanced data text generally to improve the classifier performance but they are doesn’t give significant result because data text has very diverse and large dimensions.

The purpose of this study was to determine the effect of deferred tax & tax-to-book ratio on company performance. Technological developments affect many business sectors, including the technology sector, but every company must understand the tax in their company. The population and research samples use companies on the IDX in the technology sector. There are 48 research samples from 4 years of observation 2018-2021. This study analyzes with regression analysis the research variables, namely deferred tax, tax to book ratio, company performance. The results of the study show that there is a significant influence between deferred taxes and company performance in the corporate technology sector on the Indonesia Stock Exchange. In contrast, company performance is not affected by the tax to book ratio in technology sector companies on the Indonesia Stock Exchange. Tujuan penelitian ini untuk mengetahui pengaruh deferred tax & tax to book ratio terhadap firm performance. Perkembangan teknologi mempengaruhi banyak sektor bisnis, termasuk sektor teknologi, namun setiap perusahaan harus memahami pajak dalam perusahaan mereka. Populasi dan sampel penelitian menggunakan perusahaan pada BEI di sector teknologi. Terdapat 48 sampel penelitian dari 4 tahun pengamatan 2018-2021. Penelitian ini menganalisa dengan analisa regresi variabel penelitian yaitu deferred tax, tax to book ratio, firm performance. Hasil penelitian menunjukkan ada pengaruh yang signifikan antara deferred tax dan firm performance pada perusahaan sektor teknologi di Bursa Efek Indonesia. Sebaliknya, firm performance tidak dipengaruhi tax to book ratio pada perusahaan sektor teknologi di Bursa Efek Indonesia. Kata Kunci: Deferred tax, tax to book ratio, firm performance

Public Research Organizations and universities were key players in research activities. In Indonesia, publications of Public Research Organizations were lower than universities whereas they had balanced funding. The Indonesian government had been building some strategies to improve research outputs in Indonesia by establishing national research agenda policy which encompassed national focus research areas and provision of online journal databases. This article evaluated the effectiveness of these strategies by analyzing the productivity, trend, and references of PROs publication. These analyses were conducted using bibliometrics and map visualization. The results revealed that Indonesian PROs productivity was low. Only 11% of Indonesian PROs had publications in reputed international journals. Physics science dominated the publication subject. There was a mismatch of the research area compared to the national research focus area priority. There were still many research topics which were determined as priority areas, but not many publications were produced in these areas such as research in transport and defense. The provision of journals strategy had not worked since 80% of the journal cited was unsubscribed. This study could be used to assess the effectiveness of research policy specifically for developing countries where the research budget was limited.
