Hosta Ardhyananta, ST., MSc., developed a hybrid polymer composite material that combines Indonesian natural resources with synthetic materials.<\/span><\/p><\/blockquote>\n<p><span dir=\"auto\">The development of materials technology is one of the factors driving the advancement of human civilization. Hosta explained that the increasing demand for lightweight, high-performance, and sustainable materials has given polymer composite materials significant potential in various strategic sectors. \u201cThese sectors include transportation, aerospace, energy, construction, healthcare, and defense,\u201d he explained.<\/span><\/p>\n<p><span dir=\"auto\">Furthermore, the lecturer from the Department of Materials and Metallurgical Engineering (DTMM) ITS explained that polymer composite materials are formed from a combination of a polymer matrix and a reinforcing\u00a0<\/span><em><span dir=\"auto\">filler<\/span><\/em><span dir=\"auto\">\u00a0material . According to Hosta, the matrix can come from various sources such as petroleum, plants, and animals. \u201cIn addition, natural fibers, biomass, cellulose, and microfibers also have the potential to be used as\u00a0<\/span><em><span dir=\"auto\">fillers<\/span><\/em><span dir=\"auto\">\u00a0with promising performance,\u201d explained Hosta.<\/span><\/p>\n<figure id=\"attachment_8632\" aria-describedby=\"caption-attachment-8632\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-8632 size-full\" src=\"https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_2-1.jpg\" alt=\"\" width=\"1024\" height=\"682\" srcset=\"https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_2-1.jpg 1024w, https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_2-1-300x200.jpg 300w, https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_2-1-768x512.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-8632\" class=\"wp-caption-text\">Prof. Dr. Eng. Hosta Ardhyananta ST MSc explained the implementation of lightweight composite materials in drone structures in his research.<\/figcaption><\/figure>\n<p><span dir=\"auto\">One of Hosta\u2019s key innovations is a hybrid composite material that combines two or more filler components. This hybrid composite material features\u00a0<em>spherical<\/em>\u00a0microparticle\u00a0<\/span><em><span dir=\"auto\">fillers<\/span><\/em><span dir=\"auto\">\u00a0and microfibers. \u201cThis combination of components can produce a new material with superior properties, such as low density but high mechanical strength,\u201d said Hosta.<\/span><\/p>\n<p><span dir=\"auto\">The uniqueness of this Bandung-born man\u2019s research lies in the cellulose fiber material derived from empty oil palm fruit bunches and other natural materials. Despite its abundance in Indonesia, according to Hosta, this material has not been optimally utilized. \u201cIn fact, natural fiber waste\u00a0<\/span><em><span dir=\"auto\">filler<\/span><\/em><span dir=\"auto\">\u00a0is highly valuable due to its strong bond with the epoxy matrix,\u201d explained the doctoral alumnus of Toyohashi University of Technology, Japan.<\/span><\/p>\n<p><span dir=\"auto\">Test results showed significant improvements in the material\u2019s mechanical characteristics. Hosta stated that flexural and tensile strengths increased, while the material\u2019s density remained low. \u201cThe cellulose fibers act as a bridge, strengthening the interaction between the components, thus improving stress load transfer,\u201d Hosta explained.<\/span><\/p>\n<figure id=\"attachment_8633\" aria-describedby=\"caption-attachment-8633\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-8633 size-full\" src=\"https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_3-1.jpeg\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_3-1.jpeg 1024w, https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_3-1-300x169.jpeg 300w, https:\/\/www.its.ac.id\/stp\/wp-content\/uploads\/sites\/113\/2026\/09\/Kurangi-Impor-Profesor-ITS-Gagas-Material-Komposit-Berbasis-Lokal_3-1-768x432.jpeg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-8633\" class=\"wp-caption-text\">Prof. Dr. Eng.

In the case of palm oil, empty fruit bunches (EFB) can be extracted to produce lightweight composite materials, while palm oil can be processed into biogasoline. \u201cUtilizing these local resources can reduce dependence on imported materials,\u201d he concluded.<\/span><\/p>\n<p><span dir=\"auto\">Hosta hopes that the synergy between universities, industry, and government will further strengthen the development of hybrid composite materials in the future.
