Abstract

Preparation process of 2-aminoethylsulfonic acid (taurine) from ethanolamine, sulfuric acid and sodium sulfite has been studied. The process involves two steps of reactions, the first was esterification of ethanolamine (H2N-CH2-CH2-OH) with sulfuric acid to produce the intermediate product of 2-aminoethyl ester (H2N-CH2-CH2-OSO3H) which then was extended to the second step by sulfonation with sodium sulfite to produce 2-aminoethylsulfonic acid (H2N-CH2-CH2- SO3H). These two process conditions were observed by varying mole ratio of reactants, temperature and time period of reactions. Taurine product was qualitatively analyzed using 1 H-NMR and LC-MS. Physical-chemical analysis were done by observing its melting point and determining its water, chloride and sulfate contents. Its melting point, water content, and sulfate content were 290o C, 0.303%, and 3 ppm, respectively, while its chloride content was undetected. After purification, the yield of process was 25.57%.

Abstract

Desa Pulau Raman berada di kecamatan Pemayung Kabupaten Batanghari Provinsi Jambi.  Desa Pulau Raman memiliki beragam keunikan terutama miliki makanan yang khas, yaitu kerupuk ikan lambak. Desa Pulau Raman terletak di pinggir sungai Batanghari dan memiliki sumber daya ikan yang melimpah salah satunya yaitu ikan lambak. Kerupuk ikan lambak menjadi ciri khas sebagai sumber makanan olahan masyarakat Desa Pulau Raman yang berasal dari bahan utama daging ikan lambak dan tepung tapioka. Ikan lambak merupakan ikan musiman yang hidup di dasar sungai Batanghari. Pemanfaatan ikan lambak menjadi kerupuk ikan merupakan sebuah inovasi baru yang memiliki nilai ekonomi yang tinggi, sehingga kerupuk ikan lambak ini dapat menjadi produk UMKM bagi masyarakat Desa Pulau Raman. Pada kegiatan pemanfaatan ikan lambak menjadi kerupuk mengguakan metode dengan pengambilan data yang digunakan melalui pendekatan kualitatif. Pendekatan ini diukur melalui diskusi dan wawancara dengan narasumber/subjek penelitian. Hasil dari kegiatan ini dapat memberikan manfaat bagi UP2K Raman Gemilang sehingga menjadi masyarakat yang mandiri dalam upaya peningkatan taraf perekonomian

Abstract

Modern education has transcended its traditional role as a mere transfer of knowledge and has evolved into a crucial foundation for shaping students’ character, social values, and holistic potential. This study aims to describe the level of student motivation at SMA Negeri 8 Yogyakarta in participating in table tennis extracurricular activities and to identify the dominant form of motivation between intrinsic and extrinsic factors. The research employed a descriptive quantitative approach involving 45 students who actively participated in the program. Data were collected using a Likert scale questionnaire that had been tested for validity and reliability. The results revealed that most students demonstrated moderate to high levels of motivation, with intrinsic factors such as personal enjoyment and the desire for self-improvement being more influential than extrinsic factors like teacher encouragement or environmental support. These findings underscore the importance of a developmental approach tailored to students’ interests and personal needs in managing extracurricular programs. The study contributes valuable insights for formulating strategies to enhance student participation in less popular sports activities at school.
