Abstract

Oil palm Plantation at Muaro Jambi, Jambi province already aged over 25 years, so these plants are not productive anymore and needs to be rejuvenated. By doing rejuvenation means farmers will lose income while waiting for the palm oil crop production for 3-4 years. Intercrop between oil palm plantations have great resulted in improved land productivity, increase farmers income as well as the main crop of palm maintained. Technological innovation between plants can be carried out on an oil palm plantation aged 1 to 3 years or before the plant produces. The aim is to optimize land use oil palm replanting with horticultural crops through the provision of organic matter and MPHP (Silver Black plastic mulch). The activities carried out in Mekarsari Makmur Village Muaro Jambi District. Horticultural crops that are cultivated eggplant, beans, bitter melon, squash and cucumber. The draft assessment used was a factorial randomized block design with two factors, namely: MPHP (MPHP Without and With MPHP) and the provision of organic material (Without organic fertilizers, Manure, Compost and manure + compost). For all commodities, the highest production was obtained at treatment MPHP use and manure, ie 20.9 tonnes of beans/ha, 8.99 tons of cucumbers/ha, 5.95 tons of squash/ha, 1.17 pare ton/ha and 6 , 8 tons of eggplant/ha

Abstract

Rubiana et al, 2018. Species Diversity and Community Structure of Insect in the Former Area of Coal Mining Reclamation in Muaro Jambi District, Jambi Province. JLSO 7(1):37-42. Recovery of land and ecosystems in the form of reclamation is expected to restore lost biodiversity. The success of reclamation can be seen from the recovery of ecosystems and biodiversity in it. However, the study of biodiversity on reclaimed land in Indonesia is still limited to vegetation and has not seen groups of animals especially insects. Insects have a very important functional role in the ecosystem, therefore they can be used as objects of diversity studies in the reclamation area. This study aimed to study the diversity and functional role of insects in the reclamation area. The study was conducted in the reclamation area of a former coal mine in Muaro Jambi Regency. The study area consisted of two different revegetation ages and two different plants. The method of insect collection is by installing pitfall traps with five replications for 2 x 24 hours. The insects were collected from the pitfall trap then identified to the morphospecies level. The results showed that most of the Coleoptera, Diptera, Hymenoptera and Othroptera insects were found in the reclamation area. Insect diversity is influenced by the age of reclamation. One year of reclamation had a lower species than insect age of two years. Based on the results of the analysis show that the composition of insect species showed differences at different reclamation ages. The older the age of reclamation, the composition of insect species tended to resemble the composition of insect species in the forest.
