The increasing accumulation of plastic waste poses a significant environmental challenge, with millions of tons being discarded annually. At the same time, conventional asphalt binders used in road construction often exhibit inadequate performance under high temperatures, leading to rutting and deformation. To address both concerns, this study explores the potential of incorporating recycled plastic waste into asphalt binders as a sustainable sol

Road traffic accidents remain a critical public health and economic issue in Cambodia, with traffic violations at signalized intersections contributing significantly to incidents and congestion. This study examined traffic violations at five intersections in Phnom Penh and assessed the performance of existing ANPR cameras in detecting key violations, including red-light running, motorcycle helmet non-use, car seatbelt non-use, and mobile phone us

The increasing contamination of microplastics (MPs) in marine environments poses significant risks to aquatic ecosystems and human health, particularly in sea salt production. This study aimed to develop a sustainable coconut coir filter to remove MPs from seawater at sea salt farms. Experiments were conducted using a batch glass column (10 cm × 10 cm × 40 cm) containing cleaned Coconut coir, supported by layers of gravel (10 cm) and sand (4 cm).

The transboundary floodplain corridor extending from Prek Kdam Bridge and Khsach Kandal in Cambodia to the Vietnamese Mekong Delta represents a critical component of the Lower Mekong Basin’s hydrological and socio-ecological system. Seasonal inundation within this corridor underpins agricultural production, sustains capture fisheries, and supports the livelihoods of millions of rural households. However, this natural flood regime is increasingly

This study investigated the effects of two different water sources, artificial seawater prepared with Red Sea Salt and natural brackish water from Kampot, on the water quality dynamics, growth performance, and survival of mud crab (Scylla serrata) cultured in a recirculating aquaculture system (RAS) under indoor conditions. The experiment was conducted over 60 days using a controlled setup where individual mud crabs were stocked separately to red

The Discrete Element Method (DEM) is widely used to simulate biomass material handling, but accurate simulation requires appropriate parameter calibration. This study calibrated DEM parameters for fibrous and irregular biomass materials, including sawdust (SD), tree leaves (TL), and a 70:30 SD:TL mixture, which exhibit more complex flow behavior than conventional granular materials. A fixed funnel method was employed to measure the static AoR of

Japanese oysters are rich in nutritional value and contain the fundamental flavor compounds desired in the oyster sauce, while green mussels and clams offer nutritional equivalence and lower cost. In Cambodia, a market analysis presently indicates a lack of commercial oyster sauce incorporating with green mussels and clams. Therefore, this study aimed to develop the oyster sauce produced from Japanese oysters, green mussels, and clams. Four diffe

Sourdough bread is rich in nutrients, antioxidants, and distinctive flavor, contributing health benefits and extended shelf life. Therefore, the objective of this study was to compare the sourdough bread made by using different percentages (100 and 200g) of sourdough starter with and without addition of instant dry yeast (10g). All sourdoughs were fermented at room temperature for 6 hours and baked at 200°C for 25 minutes. The physicochemical ana

Pesticides are substances used to prevent, control, or eliminate pests, weeds, and other harmful organisms in agricultural and non-agricultural settings. The use of pesticides in intensive agricultural areas of Cambodia poses significant risks of pollution of groundwater resources. This study investigates pesticide residues in groundwater from Koh Thum district, Kandal Province, and Kanghot area, Battambang Province. Five groundwater sampling sit

Soy sauce is a traditional brown liquid condiment widely used in Asian cuisine to enhance taste and flavor. In Cambodia, the quality of local soy sauce products remains limited. Koji mold is the key microorganism used to improve the quality of soy sauce. This study aimed to improve the quality of soy sauce by using different koji molds including Aspergillus oryzae and Aspergillus sojae. The physicochemical characteristics of koji and enzymatic ac
