Thermomechanical Properties of Natural Rubber/OPEFB Composites With Hybrid Latex–Starch Coupling Agent

Macromolecular Symposia, EarlyView.
ABSTRACT Natural rubber composites remain essential for industrial applications in Indonesia, particularly in tire manufacturing, where improved rigidity and strength are required. This study investigates the use of oil palm empty fruit bunch fiber as a sustainable filler to enhance the thermomechanical properties while promoting agricultural waste ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Physical properties of oil palm fresh fruit bunch varieties

Science, Technology, and Communication Journal
Identification of oil palm fresh fruit bunches (FFB) based on variety is a crucial step in sorting and grading FFBs to produce good-quality crude palm oil (CPO). Most palm oil mills receive two varieties of FFBs at the reception stations, Tenera and Dura, and only a certain percentage of the Dura variety is allowed in a transporting truck.

University Students' Utility Value of Learning About a Local or Nonlocal Environmental Socioscientific Issue: Written Reflections and Instructional Contexts

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Socioscientific issues (SSIs) are central to science education, yet empirical research on learners' perceived relevance in SSI teaching and learning remains limited. Utility value is a relevance construct that refers to the perceived usefulness of learning for learners' lives.

A RIPENESS STUDY OF OIL PALM FRESH FRUIT AT THE BUNCH DIFFERENT POSITIONS

Jurnal Keteknikan Pertanian, 2020
The paper aims to study the position of the optimum oil palm ripeness at the bunch different positions. This information is essential to complete a measurement procedure to detect oil palm fresh fruit bunch (FFB) maturity so that the detection devices can directly measure the optimal mature position as a representative of the entire FFB characteristics.

Interannual dynamic resource selection patterns of the northern bobwhite in a region with poor edaphic conditions

Wildlife Biology, EarlyView.
Understanding an organism's shifting resource needs throughout its life cycle is crucial for developing effective conservation strategies. Northern bobwhite Colinus virginianus populations have been declining for nearly a century due largely to habitat loss/degradation.
