Abstract

Plasticizer and filler have important role to making thermoset rubber. The function of plasticizer is to assist spreading process of filler in rubber and to improve elasticity of thermoset rubber. Meanwhile function of filler is to increase mechanical properties of thermoset rubber. The purpose of this study is to obtain the best conditions of the vulcanization process in the manufacture of thermoset rubber with coconut oil as plasticizer and fly ash/carbon black as filler hybrid, whichis the variation of cococnut oil content are 2,5 phr, 5 phr and 7,5 phr and filler hybrid FA/CB content are 30 and 50 phr with ratio 100/0 , 50/50 and 30/70. The results of thermoset rubber will be tested, it’s mecanical properties such as tensile strength, elongation at break, tension set, abrasion, hardness, and water absorption also thermoset rubber morphology. Based on average yield mecanical properties and morphology tested is obtained that the best conditions vulcanizationprocess is thermoset rubber with coconut oil content 5 phr and filler hybrid content of 30 phr with ratio FA/CB of 30/70. The best mechanical properties was given on tensile strength 24,8 MPa, elongation at break 816 %, tension set 2,17%, hardness 54±5 shore A, abrasion resistance 0,14 mm3/kg and also for water absorption 0,59%Keyword : Carbon Black, Fly Ash, Filler, Plasticizer, Thermoset Rubber, Vulcanization

Abstract

Abstrak: This research is motivated by the dominant low education of farmers. The purpose of this study was to determine the influence of plantation development on the welfare of the community in Rambah Hilir District, Rokan Hulu Regency. The population in this study were farmers in Rambah Hilir District, Rokan Hulu Regency, consisting of 150 farmers who chose samples using the Slovin formula to produce 60 samples. In collecting data, namely by interviewing and distributing questionnaires with research instruments. Furthermore, to analyze the data using the chi-square test. When viewed from the results of statistical analysis with the chi-square test, it can be seen that Asymp. Sig. (2 sides) 0.000. This value is less than 0.05. So it can be concluded that there is an effect of plantation development on the welfare of the community in Rambah Hlir District, Rokan Hulu Regency.Key Words: Education, Price, Farmers' Income, Chi-Square Test

Abstract

Penelitian ini dilatarbelakangi oleh dominannya pendidikan petani yang masih rendah. Tujuan penelitian ini adalah untuk mengetahui pengaruh pengembangan perkebunan terhadap kesejahteraan masyarakat di Kecamatan Rambah Hilir Kabupaten Rokan Hulu. Populasi dalam penelitian ini adalah petani di Kecamatan Rambah Hilir Kabupaten Rokan Hulu yang terdiri dari 150 petani yang memilih sampel dengan menggunakan rumus Slovin sehingga menghasilkan 60 sampel. Dalam pengumpulan data yaitu dengan wawancara dan penyebaran kuisioner dengan instrumen penelitian. Selanjutnya untuk menganalisis data menggunakan uji chi-square. Jika dilihat dari hasil analisis statistik dengan uji chi-square, dapat diketahui bahwa Asymp. Sig. (2 sisi) 0,000. Nilai ini kurang dari 0,05. Sehingga dapat disimpulkan bahwa terdapat pengaruh pembangunan perkebunan terhadap kesejahteraan masyarakat di Kecamatan Rambah Hilir Kabupaten Rokan Hulu.
