Abstract

China is one of the main export destination of Indonesian agricultural commodities. Nevertheless, the export trend of Indonesian agricultural commodities to China during  2012-2016 tend to declined, therefore it is necessary to analyze it. This research aimed to analyze the determinant of Indonesian agricultural commodities export demand by China. Indonesian agricultural commodities export demand was estimated using a regression model on panel data. Panel data in this research consisted of ten data of Indonesian agricultural commodities export to China during 1999-2016 period. The results showed that Indonesian agricultural commodities export demand by China was significantly influenced by real GDP per capita of China, real exchange rate, export price of agricultural commodities and import tariff of agricultural commodities in China.An increasing in real GDP per capita lead an increase in Indonesian agricultural commodities export demand. The depreciation of Rupiah which was expected to increase export demand, but in this research it decreased Indonesian agricultural commodities export demand from China.In addition, Indonesian agricultural commodities export demand tend to increased despite the export prices of agricultural commodities and import tariffs of agricultural commodities in China increased.

Abstract

In this paper, we measured the specific electro optic rotary power h of petroleum and spiritus solution in static external electric field Eex using Kerr Effect. The magnitude field to induce the samples is produced by two parallel plates (3 ´ 4 cm2) applied on varied DC high voltage 0-10 kV. Variation of NaCl solution is held on 5%, 10%, until 35%. The light source used to observe change of polarization angle is diode pointer laser 654 nm in wavelength. From the result of experiment we obtained that theh’s value of petrol is (0.1040.008) o/V and for spiritus is (0.0660.006) o/V, indicates that Petrol optics more active than spiritus one.   Key words: non-linear optics, external electrics field, specific electro optic rotary power

Abstract

ABSTRACT This article aims to describe the codicological aspects of the Qur'anic manuscripts, including the historiology, form, illumination, symbols, and others. The study employed library research with primary data on al-Qur`an manuscripts at the Al-Mukarramah Sintang palace. The study found that that this manuscript is the only manuscript of the Al-Qur`an in the Sintang palace, estimated to be 340 years old, written by Sultan Abang Nata and H. Abdul Karim, and its authorship was sponsored by the Al-Mukarramah Sintang palace. The base of the manuscript is tapa bark wood typical of the Dayak community in rural West Kalimantan, indicating the integration of Kalimantan culture with the writings of the Quran at that time. Furthermore, the type of khat used in the manuscript is naskhi using black ink on the Arabic text and red ink on letter descriptions, waqaf and vowel (syakl). Seventh, there is no thick illumination, only the use of simple lines and circle models as markers of waqf and juz markers. Keywords: Codicology, Quran manuscripts, Al-Mukarramah Palace, Sintang ABSTRAK Artikel ini bertujuan untuk menjelaskan aspek kodikologi pada manus­krip al-Qur`an, seperti historisitasnya, bentuk, iluminasi, simbol dan lainnya.

Abstract

Adapting to the current condition of the COVID-19 pandemic has become crucial to keep teaching-learning going since the shift of traditional classes to emergency remote teaching. Meanwhile, teachers and students have difficulties implementing emergency remote teaching(ERT), especially in speaking classes. Thus, this present research aimed to explore the teachers' and students voices on emergency remote teaching in speaking classes to contribute to the previous related studies by employing a phenomenological study, as the research design, at a private university in Ciamis, Indonesia. The data were collected by distributing close-ended questionnaires and semi-structured interviews with 15 EFL students and 2 EFL teachers who have experienced emergency remote teaching in speaking class. The results of this study revealed that speaking class-based emergency remote teaching could be carried out interchangeably through synchronous and asynchronous platforms, namely Zoom Meeting; Google Meet; Google Classroom; and Video Recording, along with its benefits and drawbacks. Furthermore, the successful implementation of emergency remote teaching could not be separated from the solutions to overcome the problems and the school support in training teachers and students to implement emergency remote teaching and become well-trained in utilizing technology.

Abstract

Gambung green tea (Camellia sinensis var. assamica), cultivated in the highlands of West Java, Indonesia, is renowned for its unique sensory qualities and potential health benefits. Given the growing global concern over antibiotic resistance, there is an urgent need to explore natural alternatives with antimicrobial properties. This study investigated the antimicrobial and antioxidant properties of Gambung green tea extracts against clinically relevant pathogens, including Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumoniae, and Candida albicans. Crude extracts were prepared using water, ethanol, and ethyl acetate, and phytochemical screening revealed the presence of flavonoids, polyphenols, tannins, and anthocyanins. Ethanol extraction yielded the highest extract mass (37.6%) and demonstrated the most potent antimicrobial activity, particularly against S. aureus (IC50 5.0 mg/mL) and S. pyogenes (IC50 7.5 mg/mL). The ethanol extract also exhibited strong antioxidant activity, as measured by the DPPH assay. E. coli showed moderate resistance (IC50 24.34 mg/mL), while K. pneumoniae and C. albicans were less susceptible. The results highlight the potential of Gambung green tea, particularly its ethanolic extract, as a natural antimicrobial and antioxidant agent. Further research is needed to identify specific bioactive compounds and their mechanisms of action. The localized origins and unique environment contribute to the distinctive phytochemical composition and biological activities observed. Further investigation into the specific bioactive compounds and structure-activity relationships is warranted to facilitate the development of Gambung green tea as a natural antimicrobial resource.

Abstract

This study examines the effectiveness of a Case-Based Collaborative Learning (CBCL) listening e-module in enhancing the 21st-century skills of English Language Teaching (ELT) students, specifically focusing on critical and creative thinking skills. Utilizing an experimental design, 38 students participated, with an experimental group using the e-module and a control group following traditional instruction. Results from pre- and post-tests demonstrated significant improvements in the experimental group. Additionally, students’ feedback revealed high satisfaction with the module’s content relevance, multimedia integration, and scaffolded activities. These findings suggest that CBCL-based e-module is an effective tool for fostering students’ creative and critical thinking, contributing to innovative teaching practices in ELT.
