Abstract

Tanaman johar (Senna siamea) diketahui memiliki aktivitas antibakteri dan telah banyak dimanfaatkan sebagai obat tradisional khususnya daunnya. Aktivitas antibakteri ekstrak daun johar telah banyak dilaporkan mampu menghambat pertumbuhan baik bakteri Gram positif dan Gram negatif. Dibandingkan bakteri lain, Konsentrasi Hambat Minimum (MIC) ekstrak daun johar terhadap Propionibacterium acnes dilaporkan jauh lebih rendah. Namun, mekanisme antibakteri dan protein reseptor targetnya belum diketahui. Penelitian ini bertujuan untuk menentukan protein target utama dan senyawa aktif dalam S. siamea untuk memahami mekanisme antibakterinya. Metode yang digunakan adalah molekuler docking senyawa yang dilaporkan pada ekstrak S. siamea pada beberapa protein bakteri P. acnes menggunakan Swissdock. Hasil dengan konformasi paling stabil dianalisis lebih lanjut dengan metode Density Functional Theory (DFT) menggunakan Gaussian 09 pada level teori HF/3-21G dan semiempirik PM6 dilanjutkan dengan analisis Interaksi Non-Kovalen (NCI) menggunakan Multiwfn. Kesimpulan dari penelitian ini adalah lipase pembentuk biofilm adalah protein target dari senyawa polar dalam daun S. siamea terutama siamosida A.

Abstract

Conventional games are a national cultural heritage, now gradually fading and rarely found in society. This is due to the development of science and technology. This phenomenon was found among students at SDN 2 Jajar, Trenggalek Regency. Online games involve the sense of sight which is at risk of bad for children's motor and social development, while conventional games involve body parts to move, so that the body is healthier, stronger, and fitter. The population in the study included all children aged 6 to 12 years in Jajar Village. The sample included 31 students from grades one to six and 31 parents of SDN 2 Jajar students. Data collection techniques were through observation, interviews, and documentation. Data analysis techniques were descriptive qualitative. This paper explains efforts to arouse the enthusiasm and love of students at SDN 2 Jajar and Madrasah Ibtidaiyah Jajar for conventional games that are the foundation of a healthy lifestyle. The socialization was held on January 3-4, 2024, while practical activities were held on January 7 and 21, 2024. Conventional games that were socialized included Rangku Alu, Egrang, Bakiak, Gobak Sodor. The results of the socialization showed a positive response from students and parents/guardians of SDN 2 Jajar. The aim of this activity is to realize healthy children's characters to welcome the golden generation of 2045.
