Abstract

The purpose of this study was to evaluate the decomposition of organic waste into carbon microparticles under atmospheric conditions. Carbon microparticles are made by drying and carbonizing raw water hyacinth. Then, the carbon microparticles that have been produced are ground using a saw-milling apparatus. Carbon microparticles prepared from raw water hyacinth were heated in an electric heating furnace at a specific temperature for the analysis. The experimental results show that the thermal decomposition process has three steps. Water hyacinth is stable at temperatures below 100°C. As carbon decomposes at higher temperatures, the process of decomposition into smaller molecules occurs. Then, at temperatures ranging from 150 to 280°C, an effective carbonization process occurs to form carbon. The advantages gained, in this case, will provide a better understanding of how to use heat treatment on water hyacinth.

Abstract

The process in the industry requires equipment with high efficiency, especially energy. This is closely related to the need to measure the heat-transfer process in heat exchangers. A study of the effectiveness of a heat exchanger is needed to increase the effectiveness of the heat exchanger because each heat exchanger product created has different effectiveness. This study aims to discuss and explain the calculations in the design of shell and tube-type heat exchangers. A step-by-step method for calculating heat exchanger designs is presented, including reviewing simple cases regarding heat exchanger design calculations. This research has the potential to be used as standard information on how to do step-by-step calculations for heat exchanger design.
Bibliometric Data Analysis of Research on Resin-Based Brake-Pads from 2012 to 2021 using VOSviewer Mapping Analysis Computations Nandiyanto, Asep Bayu Dani; Al Husaeni, Dwi Fitria; Ragadhita, Risti

Abstract

This study examines the mapping of research bibliometric data analysis related to resin-based brake pads. The research data was collected through the publish or perish reference manager application from the Google Scholar database. The title of the study material and abstract is used as a basis for searching for availability based on the specified keywords, namely "Resin-based Brake Pads". The search results show a total of 398 articles that are relevant and used in the mapping analysis. VOSviewer is used to complete the mapping process. The study period used as the study material was articles published in Google Scholar indexed journals from 2012 to 2021. We examined the number of published articles on resin-based brake pads and their relationship to problem areas using VOSviewer. The results showed that research on resin-based breake pads experienced an increase in research interest from 2017 to 2021. The smallest number of publications occurred in 2015 with 23 publications. There are main terms that are usually discussed and related to the research theme of resin-based brake pads, namely pad material, development and epoxy resin. This review is expected to serve as a starting point for conducting research by taking the field of study of resin-based brake pads.

Abstract

Sustainable materials are essential in achieving the Sustainable Development Goals (SDGs), particularly in clean energy, water purification, waste reduction, and green infrastructure. This study investigates the role of material innovation in supporting the SDGs using a Systematic Literature Review (SLR) and bibliometric analysis (from Scopus database (2015–2025) using keywords “Sustainable Material,” “Green Material,” and “SDGs”). The findings showed a growing research trend, especially after the COVID-19 pandemic, with significant contributions from chemistry, engineering, and environmental sciences. Materials like nanomaterials, biomaterials, biodegradable polymers, and waste-derived products contribute to SDG 6, 7, 9, 12, and 13. Innovations such as green nanotechnology, bio-based materials, and circular material design show strong potential to address global sustainability challenges. These materials not only support emission reduction and waste valorization but also encourage green job creation and sustainable production. This study highlights interdisciplinary pathways to align material science with sustainable development.
