Abstract

Minyak biji karet dapat dimanfaatkan untuk pembuatan membran poliuretan. Minyak biji karet memiliki bilangan hidroksi 40,33 mgKOH/g dan bilangan iod 154,05 gI2/g. Sintesis membran poliuretan menggunakan metode ikatan silang. Ikatan silang terbentuk dengan mereaksikan minyak biji karet sebagai sumber gugus -OH dengan heksametilen-1,6-diisosianat sebagai sumber gugus -NCO. Membran poliuretan yang optimum dihasilkan pada komposisi 4,55:5 (g/g) memiliki sifat homogen, kering, elastis, berwarna kuning kecoklatan, bergelombang, fluks 0,544 L/m2.h.bar dan faktor rejeksi 100%. Hasil karakterisasi membran menunjukkan terbentuknya ikatan uretan pada bilangan gelombang 3480 cm-1, struktur morfologi membran padat, memiliki dua tahap dekomposisi pada 210 oC dan 392 oC, titik transisi gelas 65 oC, kekuatan tarik 1,03 kgf/mm2 dan elongasi 497,14%. Dari hasil karakterisasi membran poliuretan, membran tersebut dapat digolongkan pada tipe membran reverse osmosis.

Abstract

This study aims to analyze the da'wah messages contained in the lyrics of the song "Luahanku" composed by Ustadz Adnin Roslan, as well as to explore the role of social media in strengthening the dissemination of these messages. This study analyzes the da’wah messages in the song "Luahanku" by Ustadz Adnin Roslan, focusing on the values of aqidah (faith), akhlak (morality), and syari’ah (Islamic law) conveyed through the lyrics, using qualitative content analysis with a cognitive semantic approach. The research also explores how social media platforms like Facebook, Instagram, and YouTube amplify these messages, enabling wider dissemination and interaction between the message sender and audience. Findings show that the song emphasizes strengthening belief in Allah (aqidah), promoting ethical behavior and self-improvement (akhlak), and providing guidance for religious duties (syari’ah), with social media playing a key role in spreading and engaging audiences through likes, comments, and shares. This study highlights the effective combination of meaningful lyrical content and digital media as a powerful tool for contemporary Islamic da’wah.
