This study analyze the effect of fiber volume fraction variation of elephant grass fibers on the tensile strength properties of polyester resin matrix composites. The research was conducted in five stages: fiber extraction, alkaline treatment using a…
This study aimed to evaluate the effects of binder type and concentration on the quality of coconut husk charcoal briquettes and to assess the potential of rice flour as an alternative binder to tapioca flour. A two factorial Completely Randomized…
Steel corrosion in acidic environments is a critical issue affecting material durability and service life. This study aims to analyze the effect of kapok peel extract inhibitor concentration on the corrosion rate of steel in sulfuric acid media and to…
Water hyacinth (Eichhornia crassipes) is an invasive aquatic weed that often disrupts irrigation channels, water quality, and agricultural water resource management, but also has the potential to be a source of lignocellulosic biomass for the…
Long beans (Vigna sinensis L.) are a horticultural crop with high nutritional and economic value. Long bean production can be increased through proper fertilization, particularly the use of NPK fertilizer containing the macronutrients nitrogen (N),…
Natural fibers as reinforcements for biocomposites continue to be investigated from various sources that are beneficial to both humans and the environment. This study aims to investigate the characteristics of Cordyline australis fibers, or Balinese…
Crop production prediction is important to support agricultural planning, resource allocation, and early decision-making in farming systems. Crop yield is influenced by various factors, including land characteristics and agroclimatic conditions. This…
Natural fibers are widely developed as composite reinforcing materials because they are environmentally friendly, lightweight, and have good mechanical potential. One of the natural fibers that has the potential to be used is elephant grass fiber…
Manual determination of mangosteen (Garcinia mangostana) ripeness still relies on human visual observation, which may lead to subjective and inconsistent assessments. This study aimed to develop a YOLOv8-based model for detecting mangosteen…
This study investigates the effect of elephant grass fiber (Pennisetum purpureum) volume fraction (5%, 10%, 20%, and 30%) on the mechanical and morphological properties of epoxy matrix composites. While conventionally limited to livestock feed, this…
Coconut is an agricultural commodity with significant development potential, as it can be processed into various high-value products, one of which is Virgin Coconut Oil (VCO). VCO can be produced through a fermentation method by adding tempeh yeast…
Water is a fundamental requirement for human liFe; therefore, water intended for consumption must be clean and meet established quality standards. In Indonesia, clean water quality standards are regulated under the Regulation of the Minister of…
