Abstract

The high rate of tool wear is an obstacle in machining of GFRP material. This research was conducted to investigate turning behavior towards the occurrence of flank wear on HSS devices by varying machining parameters such as rake angle, spindle speed and feed rate. The GFRP of workpiece was made from resin as a matrix and the glass type Chopped Strand Mat as fiber. The rack angle of tool is varied to 5º, 10º, 15º, 20º.  Taguchi method was used to analized data experiments using orthogonal array L8. The experimental data shows that the spindle speed is the most influential parameter on flank wear with a S/N ratio of 4.10, followed by the feed rate with a S/N ratio of 3.08. Increasing rake angle can reduce wear, the smallest wear value was obtained at an angle of 20º.

Abstract

When Europe was hit by the refugee crisis in 2015, Germany as the leader of the European Union implemented policies that contrasted markedly with those of other member countries. Through the Open Door Policy under the command of Angela Merkel, Germany voluntarily opened its borders so that refugees were able to enter its territory. Unfortunately, this policy triggered many protests and rejections from various circles. Among these were members of the general public, opposition parties, Merkel's own party, interest groups and the European Union as a regional umbrella for Germany. The determination of this policy did not involve the participation of the Bundestag (level I parliament) in a democratic manner, either. Despite the many objections that arose, Merkel remained adamant about defending and enforcing her controversial policy. This attitude reflects the existence of a separate perspective or perception that Merkel had in seeing the refugee crisis, so she established an Open Door Policy. This paper will shed light on how Angela Merkel's personal perception could have led to her choice of providing protection for refugees despite having to face various forms of resistance. By using the framework of the relationship between perception and decision-making according to Ole R. Holsti, it was found that belief and image systems influenced Angela Merkel's perception that Germany should be the main actor in responding to the refugee crisis that occurred in the European Union region and the rest of the world as well.

Abstract

ASEAN Agreement on Electronic Commerce (AAEC) is an agreement in Southeast Asia initiated by Singapore that aims to facilitate cross-border e-commerce cooperation in the region. This research analyzes the role of Singapore in the ASEAN Agreement on Electronic Commerce. The research method used is qualitative with descriptive and exploratory research using primary and secondary data. This research uses National Role Conceptions by K.J. Holsti to analyze the role of Singapore in AAEC. The researchers identify four national role conceptions, such as regional leader, regional-subsystem collaborator, developer, and example. Singapore’s role as a regional leader is evidenced by Singapore leading the e-commerce task force in the region and initiating the AAEC. Role as a regional-subsystem collaborator, Singapore shows a commitment to establishing cooperation between ASEAN member states and aims to achieve common interests through AAEC. Singapore collaborated with Malaysia and Brunei Darussalam in the e-commerce task force. Singapore actively cooperates with other ASEAN member states to implement the area of cooperation in AAEC. Singapore’s role as the developer has developed Singapore Cooperation Centres in Vietnam, Cambodia, and Lao PDR aims to give training and workshops about e-commerce. The role as example, Singapore is a country with the most advanced e-commerce infrastructure in the region and becoming an example for other countries. Singapore inspires other ASEAN member states to support the implementation of AAEC. Keywords: ASEAN Agreement on Electronic Commerce, Southeast Asia, E-Commerce, National Role Conceptions, Singapore.
