Abstract

The Guided Question Technique (GQT) has recently caught the interest of researchers. Although many studies have explored the effects of GQT on skills like reading and speaking, there are relatively few investigations into its impact on students' writing abilities, specifically in crafting descriptive texts. This paper aims to examine whether the guided question technique (GTQ) can enhance students' writing skills, specifically in composing descriptive texts. To achieve the study's objective, seventy students from SMA Negeri 7 Palu in Indonesia were purposively divided into two groups. One group received treatment from a researcher, while the other did not. The findings demonstrated a notable distinction between the treated and untreated groups. Students who received the treatment performed better in writing descriptive texts than those who did not. The results of this study clearly showed that employing the guided question technique in teaching writing skills was advantageous for intermediate-level students in writing descriptive texts. These findings have implications for teacher and other researchers.

Abstract

The objective of this study was to examine whether the application of POSSE (predict, organize, search, summarize, evaluate) strategy could enhance the understanding of reading skills of tenth-grade pupils in SMAN 7 PALU. This study utilized designing quasi-experimental, dividing participants into an experiment group and a control group. The technique of purposive sampling was employed to decide the sample, comprising 36 students from the experimental group and 35 pupils from the control group. Gathering of data involved pre-test and post-test assessments, with analysis conducted utilizing paired sample t-tests with the support of SPSS v.29 for windows. The findings indicated that applying of the POSSE approach effectively enhanced the understanding of reading among tenth-grade students attending SMAN 7 PALU. This conclusion was substantiated by the results of conducting the paired sample t-test, which showed a statistically notable disparity (2-tailed=0.0010.05) in the students’ learning outcomes between the initial assessment and subsequent assessment.

Abstract

Kegiatan pengabdian ini dilatarbelakangi adanya salah satu hasil penelitian tentang penguasaan bahasa Inggris di Indonesia yang masih rendah dan belum memberikan harapan yang baik. Data menunjukkan bahwa materi grammar bahasa Inggris paling membingungkan, diikuti oleh materi berbicara (speaking) sulit dipelajari. Dengan demikian tujuan dilakukan pengabdian ini adalah Peningkatan Minat Belajar Bahasa Inggris melalui Metode Small Group Discussion Siswa SMP IT Qurrota A’yun, Palu. Tahapan pelaksanaannya melalui metode pendekatan pembelajaran berupa kegiatan edukasi terhadap proses pembelajaran bahasa Inggris yang merujuk pada proses belajar bersama dalam bentuk ‘Small Group Discussion’. Hasil pengabdian yang telah dilakukan dalam bentuk pelatihan menunjukkan bahwa model pembelajaran ‘small group discussion’ membuat semua peserta didik aktif dalam kegiatan belajar mengajar, mengajarkan kepada peserta didik menghargai pendapat orang lain dan bekerjasama dengan teman yang lain, melatih dan mengembangkan sikap sosial dan demokratis siswa, meningkatkan keterampilan berkomunikasi bagi siswa, mempertinggi partisipasi peserta didik baik secara individual dalam kelompok maupun dalam kelas, dan mengembangkan pengetahuan mereka, karena saling bertukar pendapat antar siswa dalam kelompoknya.

Abstract

Twin wire arc spraying (TWAS) is a thermal spray process that is widely used in various industries. Nevertheless, the impact of repeated sandblasting on the coating characteristics of FeCrBSiMn coating created using the TWAS technique has not been extensively researched. Therefore, this study aims to investigate the influence of repeated sandblasting on the properties of the FeCrBSiMn coating layer created using the TWAS process. The study used stainless steel 304, 75B, and FeCrBSiMn as the substrate, bond coat, and top coat materials. The substrate materials underwent sandblasting with a repetition of 1, 2, and 3 cycles before the coating procedure. The coating's quality in this study was assessed using surface roughness, thickness, hardness, corrosion rate, bond strength, and SEM (Scanning Electron Microscope) examination. The findings of this investigation indicate that the sandblasting treatment substantially elevates the surface roughness of 304 stainless steel substrates. As the substrate surface becomes rougher, there is an increase in the percentage of porosity and unmelted material, as well as an increase in the thickness of the coating layer. Furthermore, the hardness of the resulting coating layer diminishes. Specimen A exhibited superior qualities in comparison to the other specimens. The coating layer on this specimen has a percentage of unmelted material and porosity, thickness, hardness, and adhesion of 7.122%, 0.125 mm, 1081.6 HV, and 14.5 MPa respectively. This investigation's results indicate that the substrate material's corrosion rate (x 10−6 mmpy) is 3648.6, which is lower than the corrosion rate of specimen A, which is 37.802.

Abstract

The high concentration of metallic components in the pad composite improves breaking ability at elevated temperatures and frequencies, bolstering the automobile's braking system. The brake pad operates through friction mechanisms, generating PM 10 and PM 2.5 particulate matter that is emitted into the atmosphere, adversely affecting the well-being of humans and animals. Therefore, eco-friendly materials like natural fiber and organic particles are being used as substitutes for the metal in brake pads. However, natural fibers and particles exhibit unique characteristics when interacting with other materials, presenting significant challenges in brake pad composites such as variations in physical properties, limited thermal resistance, and potential degradation at high temperatures and humid environments. These aspects play a crucial role and can affect the structural strength, wear resistance, and overall performance of composite brake pads, especially when operating under extreme braking conditions. This paper review critically discusses automotive braking systems, the benefits of non-natural fiber brake pads, the process of particle emission formation, the components and manufacturing factors of composite brake pads, and the environmentally friendly qualities of brake pads. This study provides an exciting opportunity to advance our knowledge of the presence of natural fibers and organic particles in composite brake pads, which greatly improves the performance of automotive brake systems because they have super physical and mechanical properties, as well as great tribological and thermal endurance. Moreover, eco-friendly brake pads are typically biodegradable, which helps reduce ecological damage, minimize health concerns for humans and animals, and promote a sustainable automobile sector. Furthermore, eco-friendly brake pads show great potential for further advancement in reducing pollutant emissions and enhancing performance.

Abstract

Derived from Coir coconut waste, coir fiber offers an environmentally friendly response to ecological challenges in various industries. Its application aligns with achieving Sustainable Development Goals (SDGs), such as eliminating extreme poverty, ensuring food security, and promoting decent employment and economic expansion. It also fosters environmentally friendly consumption and production, mitigates global warming, and conserves biodiversity. The study involves a comprehensive review of current literature, examining the methodologies including extraction techniques, surface modifications, and manufacturing processes like hand layup, casting, compression molding, hot pressing, and injection molding. The analysis identifies key improvements in mechanical, thermal, and physical properties of coir fiber composites, particularly enhanced tensile strength, thermal stability, and reduced water absorption due to chemical treatments. This confirms previous findings and contributes toward enhancing our understanding that coir fiber is extensively utilized in multiple industries, including housing, construction, transportation, biomedical, wrapping, electrical power, communication technology, biofuel, and bioenergy due to their natural abundance, affordability, ease of shaping, superior durability, and eco-friendly characteristics. Another crucial practical implication is that coir fiber and its composites offer numerous advantages that have significant consequences for the development of coir fiber in various fields.
