Publisher : Pascasarjana Universitas Negeri Medan

Abstract- The aim of this research was to compare whether polyglycerol (PG) acrylic plasticizer is more compatible and has good thermal stability than PG acetate plasticizer or even DOP plasticizer. PG acrylic plasticizer producted from polymerization of glycerol and then esterification with acrylic acid and can used as a plasticizer for PVC. Based on tensile strength and elongation analysis can be concluded that PG acrylic-DOP plasticizer (tensile strength 37.33 MPa and elongation 277.2%) is more compatible for PVC than DOP plasticizer (tensile strength 5.4 MPa and elongation 230.33%) and PG acrylic plasticizer (tensile strength 18.67 MPa and elongation 89.7%). PG acrylic-DOP plasticizer also more compatible than PG acetate plasticizer for PVC. According to DTA analysis can be concluded that PG acrylic plasticizer has thermal stability alike with PG acrylic – DOP plasticizer in PVC matrix and better compared with DOP plasticizer. This can be proven by the increase of decomposition (exoterm) temperature PG –acrylic plasticizer in PVC (from 490 oC to 500 oC) alike with PG acrylic-DOP plasticizer (constant 490 oC) andhigher than DOP plastcizer (from 490 oC to 400 oC). According to tensile strength, elongation and DTA analysis can be concluded PG acrylic-DOP plasticizer is a better plasticizer in PVC matrix than PG acrylic, PG asetate, and DOP plasticizer.

Abstrak-English for Chemistry (called Bahasa Inggris Kimia, BIK in Indonesia) is a mandatory course which is supported students professional of student support department of chemistry or chemistry teacher candidates in order to increasing mastery the contents (chemistry). Development Method of teaching materials course (also called Students worksheet, called LKM: Lembar Kegiatan Mahasiswa) followed the design of Plomp. Plomp design consists of three stages such as: a preliminary study (analysis of the needs and characteristics of learners), Products (prototype) and Evaluation (validation of the product). After prototype instructional materials formed, it pay attention to analysis of matching the needs and characteristics of students, then the product validation both self-evaluation and validation by experts have been conducted. Validated is by Contents specialist (chemical education experts) and expert in English. All inputs and suggestions suitable is accommodated in order to produce a product appropriately used by learners. The results of product testing of LKM on a freshman-2014/2015 shows the students are motivated to learn by way of active learning.
