Abstract

College students are required to complete an undergraduate thesis as part of their final project. However, when addressing the issues students face with their limited vocabulary, their choice of proper grammar, and their syntactical or word class problems, etc., researchers seldom carried out a focused exploration on dominant sentence types. This study aims to identify the most dominant sentence type used by the students in their writing, determine the forms of sentences used within the dominant sentence type, and analyse the factors influencing students' writing. This research used a quantitative descriptive method with an innovative methodological approach, namely a fishbone diagram to analyse the underlying factors. 105 background proposals from 7th semester students in the English Department at Tadulako University participated in this study. A simple random sampling technique was employed, and questionnaires and document analysis were used as instruments to gather data. The data analysis results show that: (1) simple sentences made up the majority of the dominant sentence types used in students’ backgrounds; (2) nominal sentences were the second most common form of dominant sentences used by the students; and (3) there are three factors that impact students' writing, particularly regarding sentence types: internal and external factors. The implication of this research is the development of writing skills where sentence types are an essential part of writing. The results can aid students in crafting clear and coherent sentences, specifically how to structure sentences effectively to convey their ideas logically, avoiding run-on sentences or fragments that can obscure meaning.

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

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.
