Abstract

Daun salam (Syzygium polyanthum) adalah tanaman rempah yang dikenal memiliki kandungan fitokimia seperti flavonoid, tanin, dan terpenoid yang bermanfaat untuk kesehatan. Penelitian ini bertujuan untuk mengoptimalkan metode ekstraksi pada daun salam (Syzygium polyanthum) menggunakan metode konvensional (maserasi) dan green extraction, yaitu Ultrasound-Assisted Extraction (UAE) dan Microwave-Assisted Extraction (MAE), serta untuk mengidentifikasi profil senyawa kimia dan potensi antioksidan dari ekstrak yang dihasilkan. Perbandingan langsung antara metode konvensional dan green extraction untuk mengoptimalkan potensi bioaktifnya merupakan kebaruan dari penelitian ini. Penelitian ini berkontribusi dalam pengembangan metode ekstraksi yang ramah lingkungan dan efisien serta mendukung pemanfaatan tanaman lokal sebagai sumber alami antioksidan potensi dalam aplikasi farmasi dan pangan. Analisis karakterisasi senyawa bioaktif dilakukan menggunakan Gas Chromatography-Mass Spectrometry (GC-MS) dan pengujian aktivitas antioksidan dilakukan dengan metode peredaman radikal bebas DPPH.  Hasil penelitian menunjukkan bahwa metode green extraction khususnya UAE dan MAE lebih efektif dalam mengekstrak senyawa bioaktif dengan peningkatan jumlah senyawa terekstraksi dibandingkan metode maserasi. Sebanyak 41 senyawa bioaktif termasuk golongan alkaloid, fenol, terpenoid dan asam lemak hanya ditemukan melalui metode green extraction. Dari pengujian antioksidan, semua ekstrak menunjukkan aktivitas antioksidan yang sangat kuat (nilai IC50 <50 ppm). Ekstrak UAE menunjukkan aktivitas tertinggi dengan IC50 sebesar 10,22 ppm, diikuti MAE dengan IC50 sebesar 19,30 ppm, sedangkan maserasi menghasilkan IC50 sebesar 27,28 ppm.

Abstract

If we want to try, there are many ways you can do, in terms of entrepreneurship, for example, there are waste bank activities. For some people, managing waste is an activity that is underestimated, an activity that has little economic value and is a profession for the lower classes. However, recently the concept of a waste bank has been able to ward off this negative stigma, as it has been proven that many waste business actors have made huge profits. This is proof, whatever the form of business and profession, if done properly and correctly, can provide maximum benefits. This study was conducted to analyze the activities of the waste bank, so that the potential economic value is known. This research is qualitative with descriptive analysis, in which the exploration of phenomena is done naturally. The object of this research is the waste bank group in Pamulang, South Tangerang. The research data were obtained through in-depth interviews, discussions, observations, and documentation. The results obtained information, that the waste management business is an activity that has economic value. As for the size of the economic value, it really depends on skills in managing waste and marketing it to the community. Thus it can be said that in waste bank activities there are opportunities or economic value obtained, but expertise in managing waste and the ability to sell processed products are the determining factors, how these opportunities can become one of the community entrepreneurial activities.
