Implementation of Practicum Worksheets Based on Guided Inquiry on the Topic of Colloids to Improve Students' Science Process Skills

open access: yesJIPI (Jurnal IPA dan Pembelajaran IPA), 2022
Currently, a lot of learning focuses on cognitive achievement, which results in less involvement of students in learning. Whereas in the renewable curriculum students are required to have ability incognitive, affective and psychomotor.

Ant System Algorithm in Renewing Pheromone for Completing Quadratic Assignment Problem

open access: yesJournal of Physics: Conference Series, 2020
Abstract Quadratic Assignment Problem (QAP) is often encountered with facility layout issues. Facility layout is a matter of assigning n facilities to n locations to minimize the total cost of the assignment. The QAP application examined in this research is the layout of the production facilities at PT. Slamet Langgeng.

How can renewable assignments enhance students’ graduate attributes? Insights from an action research project

open access: yesASCILITE Publications, 2022
This paper presents insights from an ongoing action research project conducted at an Australian regional university that is exploring the potential of renewable assignments for developing students’ graduate attributes. A renewable assignment task, where students create artefacts for assessment that become openly licensed, was run in two postgraduate ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

open access: yesAdvanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Graphene Quantum Dot‐Induced Microstrain for Framework Stabilization of High‐Entropy Prussian Blue Analog in High‐Current Alkaline Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Joint User-Channel Assignment for Efficient Use of Renewable Energy in Hybrid Powered Communication Systems

open access: yes2015 IEEE Global Communications Conference (GLOBECOM), 2014
In this paper, we introduce a new green resource allocation problem using hybrid powering of the communication system from renewable and non-renewable sources. The objective is to efficiently allocate the power delivered from different micro-grids to satisfy the users' requirements.
