This article develops a dynamical systems model to simulate the flows and loss mechanisms of fresh fruit bunches (FFB). Formulated as a system of differential equations, the model represents FFB stocks and associated flows while incorporating explicit loss terms. The existence of a unique and globally stable steady state, which represents the equilibrium proportion of total FFB loss, was proven. Subsequently, the parameterisation approach combines small-scale survey data from 27 smallholders in southern Thailand, which has the highest concentration of oil palm plantations, with assumption-driven values based on official statistical records, academic literature, and expert insights. Scenario and sensitivity analyses were conducted to identify the key drivers of FFB loss. This model-based analysis indicates that the most effective strategies for reducing FFB loss are those that focus on improving harvest efficiency while simultaneously optimising in-field operational practices, thereby supporting more sustainable palm oil supply chain management.<\/p>

The purpose of this study was to investigate the best ratio of waste foundry sand (WFS), fly ash (FA), and electric arc furnace slag (EAF slag) for the production of geopolymer bricks. In this research study, WFS, FA, and EAF slag were mixed at the ratio of 70:30:0, 60:30:10, 50:30:20, and 40:30:30 with 8M sodium hydroxide (NaOH) and 98% purity sodium silicate (Na2SiO3) with a ratio of Na2SiO3\/8M NaOH = 2.5. The mixtures were compacted in 5 cm \u00d7 5 cm x 5 cm molds and cured at an ambient temperature for 28 days. Then, their compressive strength was analyzed. The results showed that the geopolymer bricks with the highest compressive strength were those mixed at the 40:30:30 ratio, with a compressive strength of 25.76 MPa.<\/p>\n","protected":false},"author":3,"featured_media":12308,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"elementor_header_footer","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[236],"tags":[],"class_list":["post-12306","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-academic-paper"],"_links":{"self":[{"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/posts\/12306","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/comments?post=12306"}],"version-history":[{"count":5,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/posts\/12306\/revisions"}],"predecessor-version":[{"id":12312,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/posts\/12306\/revisions\/12312"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/media\/12308"}],"wp:attachment":[{"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/media?parent=12306"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/categories?post=12306"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.mtec.or.th\/tiis\/wp-json\/wp\/v2\/tags?post=12306"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
