applications, especially for filtering inclusions in aluminum casting industry. To meet local need for these filters, ceramic foam is fabricated by mixing raw materials including kaolin and chamotte as base material, wood sawdust (WSD) as pore-forming agent (PFA), and carboxymethyl cellulose (CMC) with water as binder. WSD content variable: 0%, 5%, 10%, and 15% was used for this research. The mixture was then formed with dry-press method and sintered at 1200掳C to form mullite-based local filters. Characterization of samples morphology, composition, and phase were done using SEM-EDS, XRD, and XRF, while its mechanical and thermal properties were characterized by conducting STA, porosity, coefficient thermal expansion (CTE), permanent linear change (PLC), and flexural strength testing. Results showed an increase of WSD addition on the local filter increased the formation number of open-type pores in fiber form on the ceramic microstructure, no significant heat exchanges from decomposition were detected, increased CTE value from 0,0071 to 0,0371%, PLC from 0,0025 to 0,0345%, apparent porosity from 33,29 to 47,95%, and water infiltration from 18,27 to 33,05%, as well as decreased flexural strength from 13,48 to 6,33 MPa and density from 1.82 to 1.43 g/cm<sup>3</sup>. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597528', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 3 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.11">Effect of Starch Content on Morphology, Mechanical Properties, and Thermal Properties of Mullite-Based Porous Ceramic as a Candidate Filter in Aluminum Casting</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Muhammad Anis, Kristanto Wahyudi, Fajar Fatriansyah Jaka, Nur Muhammad Ariq Athallah, Bambang Suharno, Ahmad Azhari, Donanta Dhaneswara </div> </div> <div id="abstractTextBlock597526" class="volume-info volume-info-text volume-info-description"> Abstract: Research on ceramic filters, needed in the aluminum casting industry because of their ability to filter inclusions, has been done. This study's primary material to make ceramic or local filters is kaolin. The manufacture of local filters in this study uses the dry press method. In this study, potato starch with a composition of 5%, 10%, and 15% acted as a pore-former in the local filter. The local filter burned to a temperature of about 1200掳C to obtain the mullite phase. Local filter characterization used SEM, XRD, XRF, and DTA. Several tests were carried out in this study, including Permanent Linear Change (PLC) test, thermal expansion test, flexural strength test, and porosity test. The results obtained in this study show that pores on the local filter are not open, have a prolate shape, and have an average pore size of 10 to 55 m. Burning kaolin up to 1200掳C proved successful in obtaining the mullite phase. Another result of this study, the more starch content added to the material, the greater the shrinkage and expansion of the material; the highest shrinkage value on the material is 0.17%, and the highest expansion value of the material is 0,29%, the 15% values owned by potato starch. It is different in the flexural strength value, which has the highest value with 0% potato starch at 14.14 MPa and the lowest value with 15% potato starch at 5.39 MPa. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597526', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.19">Thermal Decomposition Analysis of Indonesian Natural Dolomite in Air</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Fatimatul Munawaroh, Malik Anjleh Baqiya, Zaenal Arifin, Triwikantoro Triwikantoro </div> </div> <div id="abstractTextBlock597483" class="volume-info volume-info-text volume-info-description"> Abstract: Dolomite is widely used in the construction, glass ceramics, iron and steel, pharmaceutical industries, as a source of CaO and MgO and as thermal energy storage material. Thermal decomposition analysis of natural dolomite of the so-called Jeddih limestone has been carried out. A thermogravimetry analysis (TGA) in the air evaluates the thermal decomposition of dolomite. The natural dolomite has been analyzed by x-ray flourescence (XRF) and x-ray diffraction (XRD) to test crystal structure and decomposition phase, fourier transform infra-red (FTIR) was utilized to identify the presence of functional groups. The particle morphology was observed by scanning electron microscopy. TGA curve shows that the thermal decomposition of dolomite occurs in two stages. The first stage is in temperature range of 600 - 779掳C and the second one is at the temperature 779掳C. The results are in line with the XRD and FTIR measurements. Which shows that calcite begins to grow at a temperature of 600掳C and MgO phase is observed at 700 - 900掳C. Moreover, CaO phase starts to be found at 800掳C. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597483', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 19 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.27">Investigation on Mechanical Properties of Hybrid Natural Fiber Reinforced Polymer Composite</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Shubhender Singh Yadav, Pankaj Kumar Gupta, Bachchu Lal Gupta </div> </div> <div id="abstractTextBlock597955" class="volume-info volume-info-text volume-info-description"> Abstract: The use of natural fibers in composite is increasing day by due to eco-friendly nature of the fibres and reuse of waste.

In the present article, epoxy was taken as the matrix and wool fiber for reinforcement with flax flax fiber for fabricating the composite using the hand layup technique. The impact of the hybridization of flax and wool fibers on the mechanical properties of natural fiber reinforced polymer composite was investigated. These fibers were blended in varying percentages with fixed fiber content of 5% [(100% flax fiber), (40% wool/60% flax fiber), (50% flax/50% wool fiber), (60% wool fiber/40% flax), (100% wool fiber)] with epoxy resin and sampled as F5, WF23, WF2.5, WF32, and W5 respectively. Tensile strength, flexural strength, and impact strength were investigated through experimentation. All hybrid composites outperformed non-hybrid wool fiber composites in terms of mechanical properties. The wool fiber is poor in mechanical strength which was compensated by high strength of flax fiber. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597955', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 27 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.35">Fabrication of Sand and Waste Plastic Composite Based Tile</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Y.

The study investigates the potential of these natural fibres and powders as a replacement for traditional synthetic fibres in the development of lightweight and environmentally friendly composite materials. The composites will be prepared by blending the natural fibres with a thermosetting resin matrix. Four samples are fabricated by using hand lay-up technique. The composition of the composites will be optimized by varying the fibre volume fraction and the ratio of the different types of fibres, and the mechanical properties of these materials will be evaluated using standard ASTM testing procedures. The results of the study will be used to analyze the effects of fibre content, and the inclusion of groundnut husk powder on the mechanical properties of the composites, such as tensile test, flexural test, compression test and hardness test. The findings of this research could contribute to the development of new and improved composite materials that are sustainable, cost-effective, and have desirable mechanical properties for various applications, such as construction, automotive, and packaging industries. </div> <div> <a data-readmore="{ block: '#abstractTextBlock598672', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 43 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.55">A Coin-Shaped Polypropylene Bio-Carrier Fabricated Using a Filament-Based 3D Printer for Wastewater Treatment</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Revani Widjaya, Ferry Faizal, Ujang Subhan, Sahrul Hidayat, Wawan Hermawan, I Made Joni, Camellia Panatarani </div> </div> <div id="abstractTextBlock597562" class="volume-info volume-info-text volume-info-description"> Abstract: The utilization of the moving bed biofilm reactor (MBBR) has been identified as a promising technology for reducing water pollutants. This study focuses on designing a novel bio-carrier using 3D printing technology for use in an MBBR for wastewater treatment.

However, the high price of commercial feed causes a decrease in farmers' profits, so a solution is needed to reduce feed costs. Food waste has a good potential to be used as a fish feed material. The fermentation of food waste should improve its quality and ensure that food waste is safe to use as feed material. As a result of various tests of Proximate, FTIR, SEM, and Physical Quality test it has been shown that the fermentation process can significantly improve the nutritional quality of food waste without changing the functional groups and the reduction of the particle size after the fermentation process is also capable to improve the physical quality of feed. We conclude that the fermentation process is the best method of improving the physical and chemical quality of food waste and the addition of fermented food waste meal to feed did not negatively affect the physical quality of feed produced. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597499', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 63 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.916.71">Synthesis of ZnO-Al:TiO<sub>2 </sub>Materials and their Characterization as Photocatalyst Compounds</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Inovasari Islami, Lutfi Naufal Ramadhika, Annisa Aprilia </div> </div> <div id="abstractTextBlock597555" class="volume-info volume-info-text volume-info-description"> Abstract: Photocatalyst activity relates to the active surface area between pollutants and catalyst compounds. The insertion of Al atoms as a substantial defect in ZnO structures can reduce the particle size thus the active surface area increases. Another way to raise the photocatalytic activity of ZnO is by combination with other oxide materials such as TiO<sub>2</sub> (Titanium dioxide). In this study, the ZnO-Al:TiO<sub>2</sub> powder was successfully prepared via the sol-gel method using zinc acetate dihydrate as a precursor, 0.5wt% of aluminum nitrate nonahydrate as a dopant precursor, and TiO<sub>2</sub> anatase. In order to understand the role of the combination of these two metal oxides, the concentration ratio of ZnO-Al and TiO<sub>2</sub> was varied by 1:1 (ZAT) and 4:1 (ZA4T) under low (150掳C) and high (450掳C) temperature calcination. Photocatalytic testing was carried out using a 3.2 ppm methylene blue (MB) solution under UV-A lamp irradiation for 120 minutes. The high calcination temperature facilitates the growth of ZnO-Al. Besides that, the different ratio concentrations and calcination temperatures produce different defect states in each sample. The most optimum results in the photocatalytic activity performed by ZnO-Al:TiO<sub>2</sub> 150掳C (ZAT 15) with degradation rate constant (<i>k</i>) of 0.033/min and efficiency of 97% for MB removal. The unexpected zinc vacancies defect is estimated produce at the samples in high-temperature calcination. This defect type can accelerate electron-hole pair recombination. In Addition, samples with high-temperature calcination were considered to have lower hydroxyl/oxygen bonds on the surface thus affecting the photocatalytic performance. </div> <div> <a data-readmore="{ block: '#abstractTextBlock597555', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 71 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 10 Paper Titles</p> </div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy & Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/read-and-publish-agreements">Read & Publish Agreements</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> © 2024 Trans Tech Publications Ltd.
