Mangifera sumbawaensis is an endemic wild mango from Sumbawa island. Wild mangoes have many biological activities including anticancer agents. In silico can be used to reveal the potency of wild mangoes as anticancer agent. The aim of this study are to (1) identify secondary metabolites from M. sumbawaensis leaves extract based on LC-MS/MS, (2) investigate anticancer activity of M. sumbawaensis…
The Myrtaceae family is one of the most diverse plant families and possesses significant economic value, primarily due to the presence of essential oils in its leaves, twigs, flowers, and fruits. However, overlapping morphological similarities among species within this family make identification based solely on morphological characteristics difficult. This study aims to analyze four DNA barcode…
Ixora javanica (Blume) DC. commonly known as soka, is a popular ornamental plant because of its beautiful flowers. Beyond its aesthetic appeal, this flower is rich in phytochemicals with significant health benefits, including antioxidant, anti-inflammatory, anticancer, and skin-brightening properties, making it a promising natural ingredient for safe applications in health and cosmetics.

Macrozoobenthos is one of the living organisms whose habitat is in coastal areas. This study aims to inventory the diversity of macrozoobenthos on the coast of Tanjung Harapan Village, Lingga Regency. Sampling was conducted at 3 different stations (beaches), namely Indah Beach, Pasir Kuning Beach, and Teluk Rhu Beach. Sampling using the plot method and this research was conducted in August 2023…
DNA barcodes are short DNA sequences used in molecular identification of organisms. The Fabaceae family is a member of the Fabales order characterized by pod-type fruits. This study used 30 species (consisting of 6 genera, each genus has 5 species). This study aims to analyze four DNA barcodes (rbcL, matK, trnL-trnF IGS and ITS) in the fabaceae family. This study used unilocus and multilocus in…
Famili Cucurbitaceae merupakan famili yang sangat beragam dalam tumbuhan berbiji tertutup dan sering dijadikan obat tradisional karena menghasilkan metabolit sekunder berupa Cucurbitacin B, D, E, dan I. Identifikasi dan penentuan hubungan kekerabatan antar spesies dalam famili Cucurbitaceae menggunakan lokus barkode DNA tunggal sampai saat ini masih kurang efisien. Tujuan dari penelitian ini ia…

Interview research was conducted in 15 villages in Pangean District, Kuantan Singingi Regency. The determi…
The Pandanaceae family comprises trees, shrubs, and woody lianas. Most species in the Pandanaceae family, particularly those in the genus Pandanus, exhibit morphological variations, posing challenges in species differentiation. This study aims to perform multilocus analysis using DNA barcode sequences of matK, atpB- rbcL IGS, and trnL-trnF IGS in the Pandanaceae family. The matK, atpB-rbcL IGS,…
