{"abstract":"The present study aims to the feasibility and potential application of briquettes obtained from dehydrated mahogany sawdust as a feasible and eco-friendly alternative to traditional fuels. Briquettes have been observed to be widely utilized in rural areas for culinary purposes. These briquettes are derived from various biomass sources, which contribute to the reduction of carbon emissions and the promotion of ecological consciousness in waste management and energy generation. Lantawan Municipality of Basilan, renowned for its agricultural resources, such mahogany lumber and sawdust as substantial agricultural wastes that can be potential to the production of biofuel. Notably, CMS exhibits favorable characteristics for briquette manufacturing, owing to its capacity for carbon sequestration, durability, efficiency, burning time, kindling time, and heat quality. This study aims to assess the physical characteristics, efficacy, and combustion time of CMS charcoal briquettes by means of a Likert questionnaire. Results revealed a cumulative average rating of 5.0 (Very Much liked) in all parameters expressing high praise for the briquettes' remarkable capacity. Although CMS briquettes performed well in all physical tests, proving their viability as an eco-friendly energy source, recommendation such as collection and transformation of mahogany sawdust into sustainable alternative biomass fuel, Enhancement of the efficiency and accessibility by involving Technical-Vocational-Livelihood (TVL) students in the design and creation of machines that could optimize the production process and testing briquettes to various parameters such as fixed carbon content, moisture content, and ash content to improve product yields and performances.","abstract_source":"original","authors":["Ma.Hannah Mekyl Tulop","Juliana Kazandrae Ramirez","Anwar Kolong"],"date":"2024-06-15","doi":"10.5281/zenodo.11667747","id":3069,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"b434045e0c816dd8ed1040b0b53c5b888b7d0400f5977d519170830b425f0dd9","schema":"scimatic-article/1","title":"Assessment of Physical Characteristics of Carbonized Mahagony Sawdust (Toona calantas) as Charcoal Briquettes","volume":20}
