Abstract

This study aims to determine the vegetative growth of Dendrobium sp orchids at various concentrations of liquid organic fertilizer and fertilizer intensity. This research was designed with a completely randomized design (CRD) factorial pattern. The first factor is the concentration of liquid organic fertilizer consisting of three levels, namely the concentration of 5 ml / liter (A1), 10 ml / liter (A2), 15 ml / liter (A3), and the second factor is the intensity of fertilization consisting of 1 time / week ( B1), 2 times / week (B2), 3 times / week (B3). The results showed that the interaction between the concentration of liquid organic fertilizer and fertilizer intensity significantly affected the time parameters of buds, shoot height, and number of leaves. The 10 ml / liter concentration treatment with fertilizer intensity 3 times / week (A2B3) gave the fastest shoot growth of 7.93 weeks and had the highest yield on Dendrobium sp orchid shoot height at 12 weeks after planting which was 3.5 cm and the amount Dendrobium sp orchid leaves at the end of the observation were 4.75 strands.

Abstract

As the largest island in Wallacea, Sulawesi is rich in biodiversity, of which most of flora and fauna are endemic. One of them is orchids. This study aims to investigate the species diversity, namely the number of the species and abundance of each species, as well as the species evenness of natural orchids in forest areas in Lembantongoa Village, Sigi district. This study was conducted for three months: February ? April 2017. It was designed as an exploratory research with purposive sampling and systematic sampling as methods of sampling. The species diversity and species evenness of natural orchids were analyzed using species diversity index (H') and species evenness index (E). The findings of this study show that there are currently 15 genera and 30 species living naturally in the forest of Lembantongoa village, in which 25 species are epiphytic while 5 species are terrestrial. The diversity index is categorized as moderate, the species evenness index is relatively high and the species are evenly dispersed.

Abstract

Dendrobium orchid has great potential to be developed. The problem faced in its development is the decrease of orchid productivity per square meter of cultivation area. Consequently, the less availability of orchid either in quality and quantity. Whereas, there are growth regulator substances might be used to fulfill the hormone needs of orchid to obtain optimal growth. The main constraint is how the growth regulator substance in a certain amount affected the dendrobium archid growth. The research objective is to assess the growth response of stem cuttings of Dendrobium secundum orchid in combination of concentration and application intensity of growth regulator. This research was conducted for 3 months from October to January 2018, at Orchid Green House of the Permanent Nursery of BPDAS Palu Poso, Tadulako University. The results of study showed that the best treatment was combination of NAA (1 ml) + BAP (1 ml)/liter of water applied once a week (P1), which gave the fastest shoot growth of 16.25 days and had the highest growth on the shoot height of 3.5 cm and on the leave number of 4 sheets at the age of 12 weeks after planting.

Abstract

Termites play important roles in organic matter decomposition, nutrient cycling, and soil structure in tropical rain forests. When forests are replaced by agriculture, termite species richness, abundance, and function often decline. This research was aimed to determine diversity and composition of termites in three land use types (kemiri gardens, simple and complex agroforestry). Methods of sample collection using transects with a size of about 2 x 100 m, divided into 20 sections (2 x 5 m). The collected samples were collected for identification purposes. Variables measured the diversity of termites which includes the type and number of species (species richness) found in each land use. Diversity and abundance of species of termites were analyzed using the Shannon Diversity IndexWienner. The results showed that the total number of termite species founded in all area was 6 species comprising 2 families, i.e. termitidae and rhinotermitidae. Alpha diversity of termite founded in kemiri gardens was 4 species, and 5 species founded in complex agroforestry and 3 species founded in simple agroforestry. The highest frequency of termite species was 0,5 that achieved by Odontotermes sp in kemiri gardens and simple agroforestry, while the lowest frequency was 0,05 that achieved by Schedorhinotermes sp. in candlenut gardens. Further, the Shannon species diversity Index (H?) of each land use types were 0,93, 0,95 and 1,47 in simple agroforestry, kemiri gardens and complex agroforestry, respectively.
