Abstract

Dielectric properties of ZnxNi1-xFe2O4magnetic nanoparticles (MNPs) with various Zn concentration (x = 0.2-0.8) havebeen investigated over a wide frequency range 5–120 kHz. Zn-Ni ferriteMNPs have spinel cubic structure. Thecrystallite size of the sample for x = 0.2 was about 21.5 nm and then decreases by increasing Zn concentration. For sample with x = 0.4 at frequency 20 kHz, the real dielectric constant (ε') was 35.9, imaginary dielectric constant (ε") was 20.4 and loss tangent (tanδ) was 0.6. Zn concentration would affect to availability of ferrous and ferric ions in the octahedral site which are preferentially occupied by Zn2+ion. The dielectric constants decrease with increasing frequency. The sample with at x = 0.6 has thehighest dielectric on frequency 5 kHz. The maximum AC conductivity(σAC) was 1.7 x 10-4 Ω-1 at 65 kHz observed for concentration x = 0.3. The dielectric constants and conductivity at low frequency are due to the existence of grains boundary while the dispersion in the high frequency region are due to the conducting grains.

Abstract

This study aimed at analyzing the correlation between reading and listening in TOEFL ITP test and how much reading predicts listening. It involved 50,684 reading and listening scores in 2015-2019 test periods of undergraduate students in one of the state universities in Malang. The data were collected by using standardized TOEFL ITP issued by ETS. Using Pearson Correlation Product Moment and linear regression analysis, the result demonstrated reading and listening had significant, linear, and strong correlation (.682), and reading significantly predicted 46.5% variance of listening. The results lead to the hypothesis that two language input skills, reading and listening significantly correlated and predicted one another. The result also suggested that correlation language skills not only occurred among reading and writing and listening and speaking, but also it happened in reading and listening. Moreover, the results suggested the combination of reading and listening activities in classroom activities.

Abstract

Listening proficiency is essential in language acquisition, yet both its classroom time and research are overshadowed by other skills, such as speaking and reading. To tackle the issue of limited classroom time, extensive listening is one of the most convenient and effective solutions. Selecting the materials, however, needs an equally extensive effort; especially for the authentic ones.  Therefore, this study aims to investigate the speech rate and vocabulary level of TED-Ed videos as one of the sources of authentic material for extensive listening to determine their suitability for EFL learners. The research used a quantitative descriptive design with purposive sampling. The data collection of Speech Rate is conducted by transcribing the sample videos and dividing the number of words by the length of the video, and the result is measured in terms of WPM (Word Per Minute). To get the vocabulary level, the video transcripts are put into the Vocabkitchen website to analyze the vocabulary CEFR level for each word. From the analysis, the average speech rate of TED-Ed videos is 147.4 WPM and it is suitable for all levels of EFL learners, including beginner level. Meanwhile, the CEFR level of the vocabulary is more suitable for intermediate EFL learners and beyond.

Abstract

This study aimed to analyze the juridical implications, the urgency of the new concept of default, losses suffered by creditors, and legal protection for creditors after the Constitutional Court Decision Number 18/PUU-XVII/2019. This study used a normative juridical method with a case and legislation approach. The juridical implication of the Constitutional Court Decision Number 18/PUU-XVII/2019 was the non-fulfillment of the element of legal certainty due to differences in the concept of default in the Constitutional Court Decision Number 18/PUU-XVII/2019 with the provisions of Article 1243 of the Civil Code. The urgency of the new concept of default in the Constitutional Court Decision Number 18/PUU-XVII/2019 was to provide legal protection for debtors when a default is declared unilaterally by the creditor. Losses experienced by creditors were categorized into cost losses, losses on damaged goods, and losses on profits that should be obtained. Legal protection for creditors was carried out in a preventive and repressive manner.This study aimed to analyze the juridical implications, the urgency of the new concept of default, losses suffered by creditors, and legal protection for creditors after the Constitutional Court Decision Number 18/PUU-XVII/2019.

Abstract

Utilization of natural biological resources and their ecosystems responsibly and sustainably can be achieved through environmental management efforts, such as conservation. One company undertaking such efforts is PT Pertamina Hulu Energi Ogan Komering (PHE OK), which manages a conservation area. This research involves observations in the conservation area to obtain current data (conditions and potential) and trends at the location, in order to formulate strategies for its protection and management. The study was conducted in the PHE OK conservation area in Peninjauan Village, Peninjauan District, Ogan Komering Ulu Regency, South Sumatra Province. Data and analysis were performed using vegetation analysis methods, resulting in several parameters, including Density (K), Relative Density (KR), Frequency (F), Relative Frequency (FR), Dominance (D), Relative Dominance (DR), Importance Value Index (INP), Dominance Index (ID), Margalef Species Richness Index (R), Shannon Diversity Index (H'), and Pielou Evenness Index (E). The analysis results show a positive trend, with an increase in biodiversity values from low in 2022 to moderate currently. Additionally, the R value for seedling level is moderate, while it is low for saplings, poles, and trees. The E value for seedlings, saplings, poles, and trees all fall into the high species richness category. There has been an increase in each biodiversity indicator value compared to 2022, indicating that the protection efforts thus far have produced positive outcomes. However, more extensive enrichment is needed to achieve a significant increase in biodiversity
