This research aimed to analyse the decrease in students’ cognitive load while performing laboratory activity using “VIPSTA” experiment worksheet. The subjects of the research were 72 students in grade 11. The cognitive load was measured in three aspects; intrinsic cognitive load (ICL), extraneous cognitive load (ECL), and germane cognitive load (GCL). The data were analysed descriptively to show differences in the component of cognitive loads and tested for multivariate correlation-regression to show relations between the components of cognitive load. ICL and GCL were measured inversely proportional with score of students science process skill, due to well performed science process skill and knowledge construction skill are results from low ICL and GCL respectively. Whereas ECL was measured proportionally with students’ metal effort because students bear low mental effort in thinking when the ECL is low. After the implementation of VIPSTA experiment worksheet, students obtained increment for science processing skill and knowledge construction skill and decrease for mental effort which indicated low ICL, GCL, and ECL. Meaning that the use of VIPSTA experiment worksheet enables a decrease in students’ cognitive load. Furthermore, the data analysis showed that the decrease of GCL was heavily influenced by the decrease of ICL and ECL indicating that VIPSTA experiment worksheet was able provide meaningful laboratory activity by facilitating knowledge construction through lower load in processing information and performing procedure while conducting experiment.

The most important oil crop and highest production in the world is oil palm. Crude Palm Oil (CPO) and Palm Kernel Oil (PKO) are the products of the fruit. The benefits of palm oil include being used for food, chemical industry, pharmaceuticals, health supplements and as a source of biofuels. The challenges faced by oil palm growers are the diseases and pests that attack them. This research will design of backward chaining methode for expert system that can identify diseases in oil palm to provide treatment. The designs that have been produced include: knowledge representation about symptoms, diseases and treatment, input output systems and process design which includes data flow diagrams, databases, search for backward chaining using a decision tree. This design can be implemented using various programming languages, especially database or visual programming. The results of this research are very suitable as a reference for novice researchers who are interested in expert systems. The weakness of this research lies in the research domain that only comes from literature, it has not directly involved oil palm experts.

Published: March 2021

Hollow Electron Lenses (HEL) will be installed at the High
Luminosity Large Hadron Collider to provide a continuous and
controlled depletion of beam halo particles by interaction with a
superimposed hollow electron beam, of intensity as high as 5 A,
and radii 1.1–2.2 mm for 7 TeV LHC operations. In this
paper, issues related to the propagation of high intensity hollow
electron beams are discussed and the simulations of the electron
beam dynamics with feedback to the HEL design are presented. The
main results are the rise of the electron beam accelerating voltage
from 10 kV, as in the initial proposal, to 15 kV and the
validation of the 5 T magnetic field at the main solenoids as
being sufficient to guarantee a stable electron beam.
Progress in space charge compensation using electron columns

Published: March 2021

Space charge compensation allows for increased beam current
in linacs and RFQs. A novel application of space charge
compensation, the electron column, offers the opportunity to realize
more intense beams for high energy physics in circular
accelerators. The concept relies on ionization of residual gas by
the primary beam, with electromagnetic fields used to confine and
shape the space charge neutralizing plasma. Prior experimental
efforts and simulation studies are reviewed. They indicate that
electron columns could be successfully deployed in accelerator
rings. The experimental demonstration of an electron column is
underway at the Integrable Optics Test Accelerator at Fermilab. The
experiment, instrumentation, and physics program are discussed.
