Uji Ketahanan Bibit Lonkida (Nauclea orientalis) pada Media Tanam Tercemar Air Asam Tambang di Persemaian

Abstract

Kurangnya database mengenai jenis tanaman yang adaptif dengan kondisi ekstrem di lahan tambang, mendorong eksplorasi mengenai jenis-jenis adaptif tersebut. Lonkida (Nauclea orientalis) merupakan jenis tanaman multiguna yang diketahui mampu hidup pada kondisi ekstrem seperti kondisi tergenang dan pH rendah. Penelitian ini dilakukan untuk mengukur tingkat ketahanan dan pertumbuhan bibit lonkida pada berbagai jenis media tanam tercemar air asam tambang melalui percobaan rancangan acak lengkap. Hasil menunjukkan bahwa bibit lonkida mampu bertahan hidup dan tumbuh baik pada media terkontaminasi air asam tambang. Penambahan campuran pupuk kandang pada media tanam hanya berpengaruh nyata terhadap pertumbuhan tinggi bibit lonkida. Penambahan campuran pupuk kandang kambing menghasilkan pertumbuhan tinggi yang lebih baik dibandingkan dengan pupuk kandang sapi.

The lack of a database on plant species that are adaptive to extreme conditions in mining areas encourages exploration of these adaptive species. Lonkida (Nauclea orientalis) is a type of multipurpose plant that is known to be able to live in extreme conditions such as flooded conditions and low pH. This research was conducted to measure the level of resistance and growth of Lonkida seedlings on various types of planting media contaminated with acid mine drainage through a completely randomized design. The results showed that lonkida seedlings were able to survive and grow well in media contaminated with acid mine drainage. The addition of a mixture of manure on the planting media only had a significant effect on the growth of lonkida seedling height. The addition of a mixture of goat manure resulted in better height growth compared to cow manure.
