Abstract

Konservasi genetik merupakan suatu tindakan untuk menjaga, mendokumentasikan dan mengarsipkan spesimen tertentu dalam bentuk koleksi hidup maupun koleksi genom. Pendekatan molekuler sebagai alternatif dalam konservasi genetik, umumnya dilakukan dengan mengisolasi organ tertentu hingga diperoleh materi genetiknya. Tujuan penulisan artikel ini adalah untuk melaporkan hasil isolasi DNA dari beberapa sampel tumbuhan yang terdapat di Laboratorium Treub, Kebun Raya Bogor. Isolasi DNA mendukung metode konservasi genetik dari koleksi herbarium dan Bank Biji di Kebun Raya Bogor yang sudah ada sebelumnya. Metode isolasi DNA yang dilakukan berbasis pada penggunaan 2 kit DNA khusus untuk tumbuhan dengan protokol baku pada masing-masing kit. Adapun hasil isolasi DNA dari 32 sampel menunjukkan bahwa pita DNA yang muncul menjadi tanda dari keberhasilan konservasi genetik secara molekuler. Dari 29 yang diisolasi menggunakan Kit #1. Hanya 1 sampel yang muncul pita DNA. Kemudian 5 sampel lainnya berhasil terisolasi menggunakan Kit #2. Dari 32 sampel yang diisolasi, 13 sampel muncul pita dan 19 (tidak muncul pita) dengan variasi konsentrasi DNA. Hal tersebut diasumsikan beberapa kesalahan teknis penanganan dalam proses laboratorium.

Abstract

The sandwich method is a reliable screening bioassay that can be utilized to investigate allelopathic activity of leaf litter leachates. Screening the allelopathic potential of mahogany (Swietenia macrophylla King) leaf litter in plant–plant interaction using the sandwich bioassay method has not been reported. The research objectives were to determine and categorize allelopathic potential of S. macrophylla leaf litter using the sandwich bioassay method, and to determine specific activity (EC550). S. macrophylla leaf litter. The results showed that S. macrophylla leaf litter exhibited strong allelopathic activity when compared with 46 leaf litter species and was included in the top ten of allelopathic leaf litter species. Increasing S. macrophylla leaf litter concentration was concomitant with inhibition of radicle lettuce seedling growth compared with the control. According to the linear regression analysis, the effective concentration (EC50) of S. macrophylla was estimated to be 3.25 mg D.W. eq. mL-1 and was considered to have strong growth-inhibitory activity on lettuce radicle elongation. The results suggest the possibility of allelopathic potential of leaf litter in plant–plant interaction under S. macrophylla trees.

Abstract

Indonesia is highly diverse in culture, ethnicity, religion, and natural resources. The diversity is also obvious in its cuisine. Soto is an example of an iconic Indonesian dish found in many parts of the country. Despite sharing a similar name, the recipes vary according to their place of origin. Until now, how many variants of Soto are in Indonesia is not exactly known. This review aimed to discuss the characteristics of Soto based on ingredients. Soto is a soup composed of spices-flavored broth and various solid ingredients, such as vegetables and protein-and carbohydrate-rich foods. Every region in Indonesia has a different recipe of Soto; some use non-turmeric soup or coconut milk soup. The carbohydrate ingredients are mainly soun (cellophane noodle) and potato. The protein ingredients are mainly composed of chicken, egg, and beef. Vegetables consist of bean sprouts, tomatoes, and cabbage. Fried garlic, shallot, spring onion, and crackers are added as a garnish. The diversity of the ingredient makes the distinction among Soto: diversity of locality and diversity of ingredients. Approximately 46 types of Soto are reviewed in this article. Most of the Soto recipes use chicken, bean sprouts, soun, boiled egg, garlic, white pepper, red onion, ginger, and bay leaf as the main ingredients. Soto becomes an identity of its geographical origins and has distinction based on the main recipes.
