Abstract

Marginal land is a land that has several limiting factors for a particular purpose so that it takes an effort to increase its productivity. Marginal land intended for planting activities has several limiting factors such as low soil organic matter and low pH. Efforts to increase the productivity of the marginal land can be done with the addition of fertilizer and soil ameliorant. This research aims to analyze combinations of compost and bamboo biochar, having the ability to the optimal increase growth of Neolamarckia cadamba (Roxb.) Bosser in marjinal land. The experimental design used in this research was Completely Randomized Factorial Design with two factors (compost and bamboo biochar). The addition of compost and bamboo biochar increased the height, the diameter, and number of leaves of N. cadamba. The addition of 3 kg compost and 100 g bamboo biochar (K1A1) was the best treatment to increased the height, the diameter, and number of leaves of N. cadamba.

Abstract

PT Bukit Asam had strategies to improve soil fertility in the ex-mine land using compost. The amount of compost added to the soil depend on the extent of reclamation area. Oil palm empty fruit bunch and grass are highly potential to be used as the compost materials in reclamation area. The objectives of the research were to characterize the compost from oil palm empty fruit bunch and grass, and to compare the suitability between the result of this research and nasional standard compost. Oil palm empty fruit bunch and grass were obtained from PT Bumi Sawindo Permai and reclamation area of PT Bukit Asam, respectively. Composting site was located in the ex-mine land of PT Bukit Asam. Composting method used passively aerated static pile system. The results showed that the compost characteristic of oil palm empty fruit bunch compost had a dark yellowish brown color, pH at 9.3, C/N ratio at 14, and nutrients (C-Organic, N, P, K, and Mn Total). The compost characteristics of grass had a very dark brown, pH at 7.3, C/N ratio at 7, and nutrients (C-Organic, N, P, K, and Mn Total). The compost from oil palm empty fruit bunch and grass were in accordance with the national standard of compost.Keywords: empty fruit bunch, grass, compos

Abstract

The loss of biodiversity in Indonesia is triggered by a decline in forest area. Institut Teknologi Sumatera (ITERA) in collaboration with the Indonesian Institute of Sciences (LIPI) conducts the development of the ITERA Botanical Gardens having an important role as the ex-situ conservation of flora. Reforestation activities are carried out to support the vegetation development in the botanical garden. This activity have to concern in fertilizer needs and soil ameliorant, especially in soil characteristic of ITERA botanical garden. The aim of this research is to analyze combinations of manure and bamboo biochar having the abitily to increase optimal growth of Anthocephalus cadamba (Roxb.) Miq. in ITERA Botanical Garden. The experimental design used in this research was Completely Randomized Design. The addition of manure and bamboo biochar increased height, diameter, and number of leaves of A. cadamba. The addition of 3 kg manure and 100 g bamboo biochar (B3) was the best treatment to increased height, diameter, and number of leaves of A. cadamba during 12 weeks of observation.
