Abstract

Membrane that is generally used for separation process could be made using phase inversion technique. This research aims to create polyethersulfone (PES) asymmetric membranes via phase inversion technique using solvent and Trans Membrane Pressure (TMP) as variable. SEM analysis indicated that membranes had asymmetric structure that consits of two layers which denser skin layer on the top surface and the porous support on the bottom. PES/DMF membrane showed larger pore structure than PES/NMP. The permeability coefficients of both membranes were in the ultrafiltration range. The coefficient permeability (Lp) of PES/DMF membrane was 35.769 L/m2.hour, much greater compared to PES/NMP membrane which was 15.364 L/m2.hour.bar. Molecular Weight Cut-Off (MWCO) of PES/DMF membrane was 177 Kda, meanwhile PES/NMP was 186 Kda. Performances of the membranes were evaluated  using dextrane as feed solution. PES/DMF membrane resulted in an higher flux and lower rejection than PES/NMP.Keywords: asymmetric membrane, membrane performance, Molecular Weight Cut-Off (MWCO), morphology, permeability ABSTRAKMembran yang umumnya digunakan untuk proses pemisahan dapat dibuat menggunakan teknik inversi fasa.

Abstract

Sugiarmin (2010) menjelaskan anak tunagrahita memiliki masalah tingkah laku seperti mudah beralih perhatian, hiperaktivitas, mengganggu teman atau anak lain, mudah frustasi, sering menangis, merusak benda, melukai diri, meledak-ledak dan menarik diri dari lingkungan sosialnya. Studi kasus Reza Ainun Asyifa  (2017) mendapati perilaku agresif yang paling menonjol dari anak tunagrahita adalah suka berteriak-teriak kepada semua orang, sering mengganggu siswa lain yang dianggap lemah, berbicara yang tidak sopan kepada semua orang, tidak patuh aturan di sekolah maupun rumah, dan sering mengumpat kepada semua orang. Hasil studi pendahuluan menunjukkan, pembiasaan pada anak tunagrahita dapat membentuk tingkah laku anak menjadi positif atau negatif. Penggunaan token ekonomi diharapkan dapat memotivasi anak untuk meningkatkan tingkah laku yang diinginkan dan mengurangi tingkah laku yang tidak diinginkan. Dengan demikian, Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan token ekonomi terhadap pembentukan tingkah laku anak tunagrahita. Penelitian quasi eksperimen ini dilakukan dengan memberikan perlakuan pada satu kelompok yang sama dan membandingkan hasil pre-test dan post-test setelah diberi perlakuan dengan menggunakan token ekonomi (One Group Pretest-Posttest Design). Sampel penelitian ini adalah seluruh anak tunagrahita yang bersekolah di SMPLB Bukesra. Pengumpulan data dilakukan melalui observasi tingkah laku anak. Pengujian hipotesis dilakukan menggunakan rumus  uji Z. Hasil pengujian statistik dengan taraf signifikansi 5% memperoleh hasil Zhitung= 11.75 dan Ztabel= 1.64 (Zhitung> Ztabel). Hal ini bermakna H0 ditolak dan Ha diterima. Dengan demikian, dapat ditarik kesimpulan bahwa nilai postes tingkah laku anak tunagrahita lebih baik daripada pretest. Artinya terdapat pengaruh penggunaan token ekonomi terhadap pembentukan tingkah laku anak tunagrahita.  Kata Kunci: Token ekonomi, Tingkah Laku, Anak Tunagrahita.

Abstract

This research intended to figure out the main cause of inhibiting factors in Speaking, the causes of that factor, and how to overcome the problem. Qualitative approach used to conduct the research. The subjects were students of VIII-4 graders at MTs.S Babun Najah Banda Aceh. Some instruments were questionnaire and semi-structured interview guide. The data were analysed qualitative descriptively. The results of questionnaire and interview revealed that three inhibiting factors in speaking English were articulation, lack of motivation, and pronunciation. The most inhibiting factor reached the highest percentage was pronunciation and it was a part of linguistic factors. This factor could be occurred because the students did not recognize the symbols of words. The students faced difficulty when they wanted to pronounce the words correctly, and when it happened the students commonly lost or became a trigger when they expressed their ideas English words are different from how they were written and pronounced. Hence, the students need to learn how to recognize the words’ symbols of English to ease them to make sounds (pronounce) the words consistently. To overcome the problems, this research suggested to the Englis teacher to use Audio-Lingual Method to improve students' pronunciation.
