Abstract

The integration of reading and writing has long been recognized as a crucial component in second language learning. However, most previous studies have focused primarily on linear academic texts, with limited attention to the role of multimodal reading materials in supporting students’ academic writing development. This study investigates how multimodal reading texts influence the academic writing development of English as a Foreign Language (EFL) students. Using a qualitative case study design, the study involved approximately 20–25 undergraduate students enrolled in an Academic Writing course in an English Language Education program. Data were collected through classroom observations, analysis of students’ writing samples, and semi-structured interviews. The data were analyzed using thematic analysis and qualitative discourse analysis to examine patterns in students’ perceptions and developments in their written texts. The findings reveal that exposure to multimodal texts such as infographics, visual essays, and digitally enriched articles enhances students’ ability to generate ideas, organize arguments, expand lexical choices, and engage critically in academic writing. Students also demonstrate an improved capacity to synthesize information from multiple modes into coherent written arguments. These results suggest that integrating multimodal reading materials into writing instruction can effectively support academic writing development in EFL contexts. However, the findings are limited to a single instructional setting and a relatively small participant group; therefore, caution should be exercised in generalizing the results. Nevertheless, the study provides transferable pedagogical insights for integrating multimodal reading and writing practices in higher education EFL classrooms.

Abstract

A ferrocene (Fc)-modified carbon electrode was prepared from coconut shell char (CSC), which was activated with NaOH to produce an activated coconut shell carbon (Ac-CSC). The carbon electrode was designed as a printed-carbon electrode consisting of working, counter and reference electrodes in a single piece, called a screen-printed carbon electrode, or SPCE. An Fc solution was applied to the working electrode part at 10%, 20% and 30% mass of the SPCE, producing an SPCE-Fc as an electrochemical sensor for Copper ions Cu(II) detection. The prepared activated carbon was analysed by XRD, FTIR, SEM/EDX, surface area analysis and impedance measurement to determine its diffraction pattern, available specific functional groups, morphology, elemental content, surface area and electrical conductivity. The results showed that CSC consists of 52.89% amorphous carbon, 19.65% nitrogen and 23.12% oxygen. FTIR analysis showed C=O, C=C, C-H, C-O, O-H, N-H and C-S vibrations. The Ac-CSC provided an electrical conductivity rate of 26.025 S/cm. Cyclic voltammetry analysis of the Cu(II) solution with SPCE-Fc10% provided the highest current density among the other Fc contents. Therefore, a further study used SPCE-Fc10% to determine the limit of detection (LoD), interference effects, pH and scan rate effects, the repeatability of the analysis and the reproducibility of SPCE-Fc10% for Cu(II) detection. The LoD was 0.055 mM. The electrode fabrication also showed good reproducibility, as evidenced by a repeatability coefficient (R) of 0.06. The interference test showed that the SPCE-Fc10% selectively detected Cu(II), even in the presence of 5% volume of Pb(II) and Co(II) in the Cu(II) solution.

Abstract

Soda ash (NaOH) has been used in bioethanol production in the second step destillation to increase the purity up to 90%. The destillation process will produce waste water with a high sodium content. The soda ash itself serve as an electrolyte to modify the colligative properties of the water-ethanol mixture allowing the disappearance of azeotropic point. This research aims to study the replacement of NaOH with KOH, in which the kalium is a nutrient to maintain soil fertility. This research study the thermodynamics properties, vapor-liquid equilibrium, colligative properties and also its azeotropic point in the destillation of water-ethanol mixture when KOH and NaOH were used as the additive. A model of water-ethanol mixture at a various composition of 0-100 weight % of ethanol was used. The electrolyte addition was 0.1 mol electrolyte/total weight of ethanol-water. The result shows that the addition of electrolyte into ethanol-water mixture eliminate the azeotropic point and allows the ethanol molecules to separate from water. The enthalpy of mixing between water-ethanol is 239.601 kJ/mol. It becomes 259.796 kJ/mol and 264.793 kJ/mol after the addition of NaOH and KOH, respectively. It confirming the endothermic mixing process due to different polarity between water and ethanol. The presence of electrolyte even reduce more their molecular interaction. However, the change to irregularity result a high positive entropy values that result the negative Gibbs free energy. It confirms the spontaneity of mixing. The vaporization enthalpy, Hvap, of water-ethanol mixture is 76.229 kJ/mol and it becomes 235.366 kJ/mol and 126.189 kJ/mol after the addition of NaOH and KOH. It indicates that the presence of electrolyte inhibites vaporization of water as the major component and allowing ethanol molecules to vapor producing more high purity ethanol.

Abstract

Tempuran adalah sebuah desa di wilayah Kecamatan Paron, Kabupaten Ngawi, Provinsi Jawa Timur dan terdiri dari beberapa dusun, yaitu: Bulakan (ujung timur di pinggir Jalan Raya Ngawi - Maospati), Tempuran, Tempurejo, Munggur, Melikan (di tengah jalur kereta api), Jegolan (wilayah paling ujung selatan), Bendo, dan Bakalan (ujung barat). Sebagian besar geografisnya berupa lahan pertanian umumnya persawahan, dan topografi wilayahnya berupa dataran rendah. Sebagian besar penduduk asli desa Tempuran merupakan petani dan pekerja ladang, dengan jadwal pekerjaan sesuai musim tanam dan musim petik. Sesuai dengan letak georafisnya, desa ini relative mudah dijangkau dan terbuka dari berbagai arah mata angin. Sehingga jika ada usaha mikro dan menengah yang bisa diinisiasi, tidak akan terjadi kesulitan dalam akses pemasaran maupun transport bahan bakunya. Berdasarkan hal tersebut, grup riset solid state chemistry & catalysis (SSC) melakukan pelatihan pembuatan produk sabun cair berbahan baku organik gliserin sebagai dispersan, dan asam sitrun dan/ air lemon sebagai pemberi aroma. Produk sabun cair tersebut berpotensi untuk dikembangkan sebagai usaha mandiri warga karena bahan bakunya mudah didapatkan, selain itu produk sabun cair ini serbaguna, bisa digunakan untuk membersihkan badan, cuci tangan, mencuci piring dan baju. Sehingga, kemungkinan pemasarannya masih luas. Warga mengikuti kegiatan dan dapat mempraktekkan pembuatan dan menghasilkan produk sabun cair dengan baik. Kata kunci : sabun cair serbaguna; masyarakat; ngawi;  pelatihan
