Authors: Roslan Atiyah
Published: August 2023

This study aims to contribute to current research on bilingual children's vocabulary studies and the home environment. It explored how home environments affected children's L1 and L2 vocabulary acquisition. The children in this small-scale study (n=40) were exposed to Brunei Malay (L1) alongside English (L2) from a young age, classifying the children as bilingual first-language learners (BFL). This study examines the children’s L1 and L2 language development and it used vocabulary knowledge as a measuring tool for data analysis. It also considers the home environment and parental role as factors contributing to the children’s language progress. As a result, this study found positive correlations between children's L1 and L2 receptive and active vocabulary knowledge. It also found the children’s L1 and L2 interaction at home with family members. Conversely, the findings shown that there was no significant difference between the responses of 5 and 6 year old children in their L1 and L2 comprehension as well as production tests. This study also found that children who performed well in L1 and L2 vocabulary tests come from households that were open to bilingualism. In addition, parents were open to bilingualism for their children with the condition that the children prioritised their L1 more than L2. The main motive for bilingualism for their children was to enhance their communication skills and increase their chances of future employment. Hence, parents' perception of L1 and L2 is crucial because it shapes the language usages that were exposed to the children at home.

Xenophobia in Niq Mhlongo’s Dog Eat Dog and Kopano Matlwa’s Period Pain
Authors: Zewdu Aklilu Dessalegn , Daniel Abiye
Published: August 2023

Xenophobia has been thematized in South African literature by post-apartheid novelists, and they addressed it in different manners. Two post-apartheid authors who dealt with the issue of xenophobia are Niq Mhlongo and Kopano Matlwa in their novels Dog Eat Dog and Period Pain, respectively. This paper aims to examine how Mhlongo and Matlwa portray xenophobia in their novels and explore the ways they employ to neutralize xenophobia. The paper also discusses the causes of xenophobia pointed out in the novels. Therefore, a critical analysis of the novels has been made by the writer using detailed reading and textual evidence. The analysis indicates that South Africans view black foreigners as job stealers, criminals, drug dealers, witches, and bringers of disease. The writers infused the view of black foreign characters on xenophobia to debunk the negative stereotype and attempted to neutralize it by featuring non-xenophobic protagonists. The article also concludes that Mhlongo and Matlwa reveal the role of the media and the scapegoating hypothesis as the causes of xenophobia.

Authors: Salim Amalia Nabila , Disman Disman
Published: August 2023

The low ability of students' critical thinking during the learning process is the driving force behind this research. This is based on observations made by researchers who found that students during learning activities were unable to explain the material being studied straightforwardly, draw conclusions, explain the material being studied, or identify assumptions. This is because students' critical thinking skills are less developed when the learning model is used. It is hoped that this study will be able to find out and get an overview to further develop the reasoning abilities in determining fifth grade elementary school students by applying the TPS (Think Pair Offer) learning model. This study used the Classroom Action Research (CAR) method developed by Kemmis and Mc Taggart, which is one used in this study. Classroom action research is research that describes the causes and effects of treatment, as well as describes what happens when the treatment is given. and describes the entire process from the beginning of the treatment to the impact of the treatment. In this study two cycles were used which were carried out in class V of elementary school. One lesson and four stages namely planning, implementing, observing, and reflecting are each cycle. The instruments used in this review are perception sheets, field notes, test questions, and documentation. This study found that students' critical thinking skills increased by 63% in cycle I, rising to 82% in cycle II, placing it in the very good category. From these results it can be seen that there was an increase of 19% from cycle I to cycle II. This shows that one of the elementary school TPS (Think Pair Share) models can improve the critical thinking skills of fifth grade students.

Published: August 2023

The most interesting and well-known research in the field of gold nanomaterials synthesis is the use of "green chemistry" to prepare gold nanoparticles (AuNPs). In this study, Peronema canescens leaf extract was used as the synthesis medium to successfully produce AuNPs in a way that was cheap, quick, and good for the environment. A UV-visible spectrophotometer, particle size analysis (PSA), and transmission electron microscopy (TEM) were used to find out more about the AuNPs that were prepared. The UV-visible spectrophotometer showed a surface plasmon resonance peak at 532 nm, which proves that AuNPs exist in the solution. TEM and PSA both showed that the AuNPs were mostly spherical and had an average diameter of 14.9 nm, respectively. In the presence of NaBH4, the AuNPs were found to speed up the reduction of rhodamine B (RhB), metanil yellow (MY), and 4-nitrophenol (4-NP). The results show that the AuNPs that were prepared in a new way worked very well and could be used in catalysis.

This paper reports the improved microwave (MW) absorption characteristics of some newly prepared bio-silica-barium-ferrite composites (SBFCs) of the form (x)Bio-SiO2:(80-x)Fe2O3:(20) BaO (where x = 0, 2, and 4 wt.%). These composites were prepared using the modified solid-state reaction method with simultaneous sintering at 800 and 1100 °C. SBFCs were studied to determine the impact of various bio-silica concentrations on their morphology, structure, magnetic properties, permittivity, permeability, and X-band reflection loss. Various SBFC thicknesses were simulated to determine the reflection loss curves. It has been established that the MW absorption capacity of the examined SBFCs may be altered by adjusting the bio-silica concentration and sample thickness.

New benzohydrazone compound, 4-amino-N'-[(1E)-1-(2-hydroxy-6-methyl-4-oxo-4H-pyran-3-yl)ethylidene] benzohydrazide (HL1) and its Cu(II), Ni(II), Zn(II) and Mn(II) complexes were synthesized. The structures of HL1 and its complexes were elucidated by elemental analysis and IR, UV-Vis, 1H and 13C NMR spectroscopy and mass spectrometry. The infrared spectral data of the complexes revealed that HL1 coordinated with the metal ions through azomethine nitrogen, enolic oxygen and amide carbonyl oxygen atoms, hence, HL1 behaves as a monobasic tridentate ligand. UV-Vis data revealed that Zn(II) and Mn(II) complexes adopted octahedral geometry, while Cu(II) and Ni(II) complexes had five-coordinate and square-planar geometries respectively. The mass spectra data and elemental analysis values are in accordance with the calculated values for the suggested molecular formula of the complexes, a confirmation of the 1:1 ligand to metal stoichiometry in case of Cu(II) complex and 2:1 ligands to metal stoichiometry in case of the other complexes.

PT Unilever Indonesia's stock price swings. This has a heteroscedasticity impact due to the substantial volatility of stock prices. The Box-Jenkins ARIMA method can produce accurate predictions, but it is less precise when used to predict data that has a heteroscedasticity effect. Therefore, this study uses the ARIMA-GARCH method because this model has the advantage of not seeing heteroscedasticity as a problem but instead using it to create a model. The purpose of this study is to estimate parameters using the ARIMA-GARCH technique to develop the best model using PT Unilever Indonesia's share price data and to forecast PT Unilever Indonesia's share price for the period January 20 to January 28, 2021, using the best ARIMA-GARCH model created. Forecasting results for 7 periods using the best ARIMA-GARCH model are Rp. 7,535.00, Rp. 7,511.00, Rp. 7,497.00, Rp. 7,489.00, and Rp. 7,485, respectively.

Abalon (H. asinina) sangat berpotensi untuk dibudidayakan di Desa Uwedikan, Luwuk Timur, Kabupaten Banggai, Propinsi Sulawesi Tengah. Wilayah ini adalah habitat endemik bagi Abalon dan memiliki sumberdaya alam yang masih terjaga kualitasnya. Metode budidaya tradisional menggunakan wadah-wadah yang diikatkan dan ditenggelamkan di sisi-sisi karamba jaring apung saat ini banyak dilakukan oleh masyarakat dengan kombinasi bersama budidaya rumput laut. Kedalaman wadah-wadah pemeliharaan tersebut bervariasi tergantung kondisi dimana karamba jaring apung ditempatkan. Penelitian ini dilakukan untuk untuk mengetahui adanya pengaruh kedalaman wadah pemeliharaan terhadap pertumbuhan Abalon. Penelitian dilakukan dengan desain rancangan acak lengkap yang terdiri dari tiga perlakuan (kedalaman 100 cm, 200 cm dan 300 cm) dan tiga ulangan. Hasil penelitian menunjukkan bahwa tidak terdapat pengaruh nyata dari kedalaman pemeliharaan terhadap pertumbuhan panjang, berat maupun laju pertumbuhan spesifik Abalon. Meskipun begitu, penelitian ini mengindikasikan adanya pengaruh faktor pakan alami dari lingkungan sekitar pemeliharaan yang menjadi sumber pakan tambahkan bagi Abalon sehingga muncul perbedaan pada hasil pengukuran parameter penelitian.

Jengok River has a high value for the Kutaliman community. The community utilizes the ecosystem services of the Jengok River and is inseparable from the presence of riparian vegetation, which controls water quality. This study aimed to determine riparian vegetation structure on the Jengok River, Kutaliman, Kedungbanteng district, and Banyumas Regency. The research was conducted in October-November 2022 in the Jengok riparian zone using a quadrat transect with sizes 20x20 m2 for trees dan 2x2 m2 for understoreys. Data were analyzed using the Shannon-Wiener Diversity Index (H'), the Modified Hill's Ratio Evenness Index (e'), the Margalef Richness Index (DMg), and the Important Value Index (IVI). The results show that the diversity of riparian vegetation based on the Shannon-Wiener Diversity Index (H') is a moderate category, and the Evenness Index (e') is the distribution of individuals per species evenly. Furthermore, the Margalef Richness Index (DMg) shows 4.51 for trees and 4.34 for understorey. The highest IVI in the tree stratum was Lansium domesticum Corrêa. In contrast, in the understorey stratum was Musa paradisiacal L. This indicates both species have an essential role in their community

In a p-uniformly convex and uniformly smooth Banach space, let the pair of variational inequality and fixed point problems (VIFPPs) consist of two variational inequality problems (VIPs) involving two uniformly continuous and pseudomonotone mappings and two fixed point problems implicating two uniformly continuous and Bregman relatively asymptotically nonexpansive mappings. This article designs two parallel subgradient-like extragradient algorithms with inertial effect for solving this pair of VIFPPs, where each algorithm consists of two parts which are of symmetric structure mutually. Under mild registrations, we prove weak and strong convergence of the suggested algorithms to a common solution of this pair of VIFPPs, respectively. Lastly, an illustrative example is furnished to verify the applicability and implementability of our proposed approaches.
