The outcome of this event is also published in Material Science Forum, indexed by SCOPUS.
Co-operation between Indonesia and Malaysia becomes more important, particularly in the development of application of geopolymer materials.
Starting from MIGS-1, which was held in Kuala Lumpur, Malaysia, more than 50 scientific papers (6 from Indonesia) were published at a reputable international journal.
The objectives of the event are to promote understanding and updating of geopolymer science, applications and composition.
It is also disseminations for initiation and support of international collaborative activities for development of research and technology relating to various aspects of green materials.

It is suggested that this method can be applied to other type of composite materials. 1.
Introduction Composite materials signify that two or more materials are combined on a macroscopic scale to form useful material.
Fracture Analysis Fracture analysis is carried to investigate the propagation of cracks in materials.
This mechanism of comparison could be done also on other types of fibers to explore the light weight composite materials.

Using multi-billet extrusion (MBE), a number of different cross-sections in different sizes blank hole extrusion die, in the same or a different punch extrusion speed, the flow of materials, several convergence in the mold exit, welding, forming.
As a result of a single overall blank, the forming process does not exist defect in the soldering bridge mold, forming curved pipe can withstand a higher intensity of work; The role of eccentric squeeze through the forming process to achieve the numerical simulation, analysis obtained the following results: （1）Material flow model; （2）Stress distribution （3）Velocity field distribution （4）Load changes of extrusion process Establish finite element model Suppose: （1）Material in the mold within the isothermal flow ,materials friction and friction heat between materials and mold is negligible; （2）Non-stable material flow, and flow field distribution is related with time; （3）Incompressible plastic materials; （4）Inertia force, gravity, and other volume force is negligible.

Numerous materials have been studied to find candidates that met the requirement for quality bipolar plate [9].
These materials are suitable for compression molding, transfer molding, or injection molding [9].
All materials were blended on a hot plate at 100 0C for 15 minutes.
Increasing pressure is known to reduce the inter-aggregate distance of the filler materials [7,13].

The integration of materials into fibers structure can be done in several ways.
But the easiest way of integrating new material into fibers structure is by dissolving desired materials into a polymeric solution.
Here, if the polymer solution was considered as the matrix of the composite materials, the newly integrated materials can be considered as the filler.
For polymeric materials usage in electrospinning process, PVA is a good choice of material.

In both cases model sliding friction couple was made of materials characteristic for machining processes (the rotating countersample, made of toughened steel 45 and hardened to 42 HRC, modeling a workpiece and the sample, made of sintered carbide S20S or high-speed steel SW18, modeling a tool).
The aim of both stages of the examination was to investigate influence of copper or molybdenum nanopowder addition to oil on its tribological properties manifested in tested model sliding friction couple made of materials characteristic for machining processes.
Moreover, time tests proved that degree of frictional resistance decrease depends on materials cooperating in examined couple.

Introduction There are many potential applications for rare-earth doped fluoride nano-materials such as monitors, laser materials, optical information transmission and optoelectronic devices.
The transparent ceramic materials not only have excellent mechanical and physical property, but they have high dopant concentration and uniformity compared to single crystal materials [7].
