Abstract

Dalam penelitian ini, telah berhasil diisolasi tiga senyawa baru, X, Y, dan Z, dari fraksi n-heksana daun Rhodomyrtus tomentosa (Ait.) Hassk. Ketiga senyawa ini telah diuji untuk toksisitasnya menggunakan metode BSLA (Brine Shrimps Lethality Assay), yang menunjukkan aktivitas yang signifikan dengan LC50 berturut-turut sebesar 11.60, 4.64, dan 14.34 μg/mL. Namun, hanya senyawa Z yang menunjukkan aktivitas antioksidan dengan nilai inhibisi sebesar 88.5% menggunakan metode penangkapan radikal DPPH. Karakterisasi fisikokimia menunjukkan bahwa senyawa X berbentuk kristal jarum berwarna hijau kekuningan dengan titik leleh 180-182 °C, sedangkan senyawa Y dan Z berbentuk minyak berwarna kekuningan. Penemuan ini memberikan wawasan baru tentang potensi senyawa dari daun Rhodomyrtus tomentosa sebagai sumber bahan aktif potensial untuk aplikasi farmasi dan kesehatan.

Abstract

This study discusses the challenges and opportunities faced by Indonesian Micro, Small and Medium Enterprises (MSMEs) in facing international trade in the ASEAN region and the People's Republic of China (PRC). Amidst growing regulatory complexity, MSMEs are faced with barriers such as differences in technical standards, complicated customs procedures, and limited access to market information. However, there are also opportunities from free trade agreements and regional initiatives that can be utilized to expand markets. Through a qualitative approach and literature review, this research identifies key barriers for MSMEs, including limited management capacity, and the importance of collaboration between the government and private sector in developing comprehensive solutions to improve MSME competitiveness in the global market.

Abstract

One of the religious recommendations to improve the lives of its people is through the institution of marriage. Marriage plays an important role in human life. In the East Loloan community, a common phenomenon is the very important preparation and implementation of the kelakat ritual for the bride and groom before marriage. Failure to perform or breaking this tradition is often associated with unwanted events such as trance, chronic illness, or undercooked dishes. Therefore, the families of the bride and groom are very careful in carrying out the wedding ceremony in order to avoid bad luck. The subject matter debated in this thesis is the perspective of Islamic law and customary law on the tradition of the wedding procession in East Loloan. This research is a field study with a qualitative approach. Data were obtained through interviews, observations, and documentation studies. The research approach is descriptive-comparative with a normative approach. The conclusion of this study is that although the kelakat tradition is considered valid according to custom and is passed down from generation to generation by the local community, this approach is different in principle from Islamic teachings. However, in practice in East Loloan, there are efforts to achieve similar goals between customary marriage and Islamic law, namely maintaining harmony and justice in marital relationships.
