Scientific Skill Development In Kindergarten Education Post-Covid-19
Kurnia Rita,Hainul Putra Zetra,Chairilsyah Daviq The Pacific Early Childhood Education Research Ass 2024 Asia-Pacific journal of research in early childhoo Vol.18 No.2
Introduction Literature Review Method Results Discussion This study aims to analyse scientific skill development at kindergarten level post covid 19. Nevertheless, this early finding required further investigation as classes were conducted online during the covid breakout, while science classes command experiments. This study was conducted in Pekanbaru, Riau Province, Indonesia. 400 kindergarten students from 3 different schools were recruited in this investigation. The data were analysed using descriptive quantitative and a t-test was conducted. The findings suggest that the average of kindergarten students in scientific skills is in a good category. It also illustrates that students have the ability to activate their senses to commence an observation, classification, comparison, measurement and communication on things they visualise. The figure shows that students scored higher in the comparison category (88.54%), while the measurement category witnessed the lowest number, accounting for 72.28%. To identify if there is a difference in scientific skill in gender and parents’ socio-economic status, a hypothesis test was conducted. The test shows that there is no difference in gender in scientific development among students. Nonetheless, there is a correlation between scientific skills and parents’ social status. The hypothesis test indicates that children of social status have higher science skills compared to those from lower social status.
Localised nanoscale resistive switching in GaP thin films with low power consumption
Kurnia, F.,Liu, C.,Liu, G.,Vasudevan, R.,Yang, S.,Kalinin, S.,Valanoor, N.,Hart, J. Royal Society of Chemistry 2017 Journal of materials chemistry. C, Materials for o Vol.5 No.8
<P>Nanoscale localisation of the electroforming-free resistive switching (RS) behaviour in polycrystalline GaP thin films has been observed for the first time. A combination of conductive atomic force microscopy and first-order reversal curve current-voltage measurements indicated that the grain boundaries are the preferred sites for the formation of the conductive switching filaments. It is proposed, based on TEM and XPS results, that local electrochemical migration of Ga ions along the grain boundaries plays a critical role in the switching mechanism. In the low-resistance (ON) state, the conduction mechanism was found to be the space-charge-limited current mechanism, while the high-resistance (OFF) state was governed by the Frenkel-Poole mechanism. A high OFF/ON resistance ratio (similar to 10(4)) and lower power consumption than current RS devices, in addition to the easy integration of GaP with silicon substrates, make these GaP films promising for future applications in future non-volatile resistive random access memory (RRAM).</P>
Carbon Emission Disclosure, Good Corporate Governance, Financial Performance, and Firm Value
KURNIA, Pipin,DARLIS, Edfan,PUTR, Adhitya Agri Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.12
This research aims to examine (1) the effect of carbon emission disclosure on firm value, (2) the effect of good corporate governance on firm value, (3) the mediating role of financial performance between carbon emission disclosure and firm value, and (4) the mediating role of financial performance between good corporate governance and firm value. The research sample includes 43 mining, agro, and manufacturing firms listed in the Indonesian Stock Exchange over the 2015-2017 period. Carbon emission disclosure is measured by an indicator of the Global Reporting Initiative Series of Environmental Aspect. Good corporate governance is measured by the corporate governance score of shareholder rights, boards of directors, outside directors, audit committee and internal auditor, and disclosure to investors. Financial performance is measured by return on assets, while firm value is measured by Tobin's Q. Data analysis uses the structural equation modeling. The result shows carbon emission disclosure and good corporate governance have no direct effect on firm value. On the other hand, financial performance mediates the effect of carbon emission disclosure and good corporate governance on firm value. It shows that higher carbon emission disclosure and good corporate governance are meaningless for the investor if they do not give any financial performance improvement.
The Determinants of Foreign Exchange Reserves: Evidence from Indonesia
Kurnia ANDRIYANI,Taufiq MARWA,Nazeli ADNAN,Muizzuddin MUIZZUDDIN 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11
This study aims to identify and analyze the factors that affect foreign exchange reserves in Indonesia. We consider the variables of external debt, exchange rate, inflation, and exports as explanatory factors referring to previous studies. We apply the Autoregressive Distributed Lag approach to time-series data retrieved from the Central Bank of Indonesia (BI), the Central Bureau of Statistics (BPS), and International Monetary Funds (IMF) from January 2016 to December 2018. Our results show that foreign debt, exchange rates, inflation, and exports significantly affect the simultaneous fluctuation of foreign exchange reserves in Indonesia. Partially, foreign debt has a significant and positive effect on foreign exchange reserves. The exchange rate has a significant and negative effect on foreign exchange reserves in Indonesia. However, our findings explain that inflation does not significantly affect foreign exchange reserves in Indonesia, and exports have a significant and positive effect on foreign exchange reserves. This study is expected to be useful to policymakers in managing foreign exchange reserves, so the economy of Indonesia can grow sustainably. One of the exciting things in this study lies in the model that uses the Autoregressive Distributed Log, which can explain long-term relationships through adjusted coefficient and cointegration tests.
Consumers` Perception of Mobile Internet in Australia
( Sherah Kurnia ),( Hee Jin Lee ),( Stephen Smith ) 한국인터넷비즈니스학회 2006 인터넷비지니스연구 Vol.7 No.2
This paper explores the Australian consumer`s perception of mobile Internet to identify factors that may foster or hinder its use. The findings of the survey demonstrate the importance of functionality (usefulness), an easy-to-use interface, and social networks as critical influences on both intention to use and the extent of usage of mobile Internet in Australia.
Effects of different intensities of exercise on folliculogenesis in mice: Which is better?
Fitri Kurnia Rahayu1,Sri Ratna Dwiningsih,Ashon Sa’adi,Lilik Herawati 대한생식의학회 2021 Clinical and Experimental Reproductive Medicine Vol.48 No.1
Objective: Exercise is a risk factor for infertility in women. However, research on the effects of different intensities of exercise on folliculogenesis has not yielded clear results. This study was conducted to analyze the effects of differences in the intensity of exercise on folliculogenesis in mice. Methods: Nineteen female BALB/c mice (age, 3–4 months; weight, 13–25 g) were randomly divided into four groups: control, mild exercise, moderate exercise, and high-intensity exercise. The mice in the exercise groups engaged in swimming, with additional loads of 3%, 6%, or 9% of body weight, respectively. There were five swimming sessions per week for 4 weeks, with a gradually increasing duration every week. At the end of the treatment, ovarian extraction was carried out and hematoxylin and eosin staining was performed to identify folliculogenesis. Results: There were significant differences in the number of total follicles between the control and moderate-exercise groups (p=0.036) and between the mild- and moderate-exercise groups (p=0.005). The mean number of primary follicles was higher in the moderate-exercise group than in the mild-exercise group (p=0.006). The mean number of secondary, tertiary, and Graafian follicles did not differ significantly among groups (p≥0.05). However, the number of total follicles and follicles in each phase tended to increase after exercise, especially moderate-intensity exercise. Conclusion: Exercise of different intensities affected the total number of follicles and primary follicles. The number of follicles of each phase tended to increase after exercise. Moderate-intensity exercise had better effects than other intensities of exercise.
