Abstract

Penelitian ini menggambarkan perkembangan kemampuan anak disleksia melalui model SIUUL. Kemampuan membaca adalah salah satu fungsi kemanusiaan yang tertinggi dan menjadi pembeda manusia dengan makhluk lain. Di era saat ini kemampuan membaca bagi seseorang adalah hal yang sangat penting, mengingat membaca adalah pembuka informasi dunia. Tanpa membaca manusia tidak akan pernah memahami dan mengerti perkembangan teknologi dan informasi yang berkembang sangat pesat. Fokus peneltian ini dalam rangka mengimplementasikan Model SIUUL dalam mengembangkan kemampuan membaca pada anak disleksia dengan metode penelitian deskriptif kualitatif. Dalam Model SIUUL ini anak menggunakan tugas tahapan yaitu: tahap menyimak, tahap mengucapkan dan tahap mengulang. Dimana anak dituntut untuk membacanya berulang ulang baik itu di bantu oleh gurunya ataupun di baca secara mandiri oleh anak sambil di pantau dan di simak oleh gurunya, anak sangat antusias dalam mengulang apa yang diucapkan oleh gurunya.Dengan demikian peneliti dapat menyimpulkan bahwa Model pembelajaran SIUUL dapat mengembangkan kemampuan membaca huruf hijaiyah pada anak disleksia. This study describes the development of dyslexic children's abilities through the SIUUL model. The ability to read is one of the highest human functions and is a differentiator between humans and other creatures. In the current era, the ability to read for a person is very important, considering that reading is the opening of world information. Without reading humans will never understand and understand the development of technology and information that is developing very rapidly. The focus of this research is to implement the SIUUL Model in developing reading skills in dyslexic children using a qualitative descriptive research method. In the SIUUL Model, children use the stage assignments, namely: the listening stage, the uttering stage and the repeating stage. Where children are required to read it over and over again either with the help of the teacher or read independently by the child while being monitored and watched by the teacher, the child is very enthusiastic in repeating what the teacher said. Thus the researcher can conclude that the SIUUL learning model can developing the ability to read hijaiyah letters in dyslexic child

Abstract

Fatty Acid Methyl Ester (FAME) or palm oil methyl ester is one of the palm oil derivatives in which one of the anionic surfactants that can be generated from it is methyl ester sulfonate (MES). This bio-based surfactant can reduce the interfacial tension (IFT) between oil and water. To produce a bio-based polymeric surfactant, sulfonate groups from MES were grafted onto polymer chains. Palm oil methyl ester was reacted with sulfuric acid (H2SO4) to synthesize MES. Afterwards, MES was reacted with the Ethyl Acrylate (EA) monomer to synthesize polymeric surfactant. Investigating this route to produce a bio-based polymeric surfactant has become the novelty of this study. This study showed that the best polymerization result was obtained at a mole ratio of MES to EA (1:0.5) with the highest viscosity of 14.47 mm2/s. The critical micelle concentration (CMC) analysis showed 0.5% at a mole ratio of MES to EA (1:0.5) which corresponded to the lowest interfacial tension (IFT) of 1.95 x 10-3 mN/m. Meanwhile, the contact angle gradually decreased from 58.44 to 11.79°. The polymeric surfactant, furthermore, was analyzed using FTIR and H-NMR and successfully confirmed the formation of bio-based polymeric surfactant. The core flooding experiment found that approximately 16.57% of oil could be recovered. The results of the study revealed a good potential of the polymeric surfactant to be applied in chemical enhanced oil recovery (CEOR).
