Abstract

The research was conducted to inventory and identify as well as acknowledge the correlation between vegetation type with soil arthropods in the Green Barrier area of PT Pusri. PT. Pusri green Barrier area is 28 hectares and dominated by 10 types of vegetation, such as, the Angsana (Pterocarpus indicus Wild), Bambu (Bambusa Sp), Beringin (Ficus benyamina), Buah Roda (Hura crepitans L), Jati (Tectona grandis L), Kelampayan (Neolamarckia cadamba) , Ketapang (Terminalia catappa L), Mahony (Swietenia macrophylla King), Pulai (Alstonia scholaris), and Sengon (Paraserianthes falcataria L). Soil arthropods were collected by using pit fall traps and funnel barlese-tullgren in every type of vegetation, between July-August 2015. Identification of arthropod genera Identification has been done in Entomology Laboratory of the Agriculture Plant Disease Faculty Sriwijaya University, and analysis of soil organic in the Laboratory of Soil Faculty of Agriculture Sriwijaya University. The results were obtained into 3 classes of soil arthropods belonging to the 10 orders, 28 families and 35 genera. The diversity index value of soil arthropods in various types of vegetation is classified moderately (H= 1-3), and no type of soil arthropods were dominant, mean that soil arthropods with different types spread over in the various types of vegetation in the area of Green Barrier PT. Pusri. Light intensity abiotic factors play an important role in the life of the soil arthropod communities in vegetation Sengon (Paraserianthes falcataria L) with a correlation coefficient 1.00Keywords: soil arthropods, community structure, a biotic factors, Green Barrier PT.

Abstract

The research about Characteristic of Macrozoobenthos Community With Substrates Type At Warkuk River Districk of Warkuk Ranau Selatan, OKU Selatann Regency, South Sumatera has been conducted from May 2013 to December 2015. This study aims to analysis of characteristic and makrozoobenthos composition in substrat type, analysis about physic and chemistry condition at Warkuk River. Determination of sampling sites were conducted by Random Sampling. The Sample of macrozoobenthos were identified at the Laboratory of Research Institute for Inland Fisheries Mariana, Palembang. From the results obtained, are grouped into 3 classes of macrozoobenthos namely Insecta, Gastropoda and Oligochaeta, which is classified into 9 orders consists of 14 families, 16 spesies. Density ranging from 1155,56 to 1755,56 individuals/m2. Level of diversity are high, ranging from 1,95 to 2,41 and dominance index ranging from 0,31 to 0,40. Family Biotic Index (FBI) ranging from 3,47 to 3,98 with the water quality category of excellent.Key words       : Warkuk River, Macrozoobenthos, Substrat Type

Abstract

The study was conducted to determine birds in Green Barrier PT. Pusri and explains the function of the existing vegetation in the Green Barrier for many species of birds. Retrieval of data was conducted in a 28 ha Green barrier area of PT Pusri, during July to August 2015. The collecting of data determined by line transects through observation directly. assuming the selection of sites in the area of water resources and representation of vegetation types that represent a potential habitat for birds. Birds observed then identified and recorded the type, activity include, nesting, feeding, perch and plants that exploited. The results of this study found 17 species in 13 families. Plant species are most frequently used by birds is batai wood (Paraserianthes falcataria). Recorded at least 10 species of birds found in the Green Barrier PT. Pusri utilize these plants as a perch, feeding and nesting. The availability of water in the form of an artificial fish ponds at the fish pond 1 (transect 3) to attract water birds such as; Javan Pond-heron (Ardeola spesiosa) and Common Sandpipers (Tringa hypoleeucos) to come looking for food that needs to be managed to maintain its function as a habitat for birds.Keywords: Birds, plant, habitat, Green Barrier PT.

Abstract

Drought stress is one of the important issues related to the global warming that demand for the development of drought tolerant crops. Eggplant is one of the agricultural commodities which can be developed in dry land so plant growth of eggplant need to be learned. The objectives of this study were to study the effect of several concentrations of polyethylene glycol (PEG) on the in vitro growth of eggplant, and to find the drought tolerant eggplant accessions in dry land. The experiment  was conducted at the Laboratory of Tissue Culture, Department of Agronomy and Horticulture, Bogor Agricultural University. The experiment was laid on a completely randomized design with one factor. The factor was eggplant accessions. The results showed that PEG in vitro media significantly affected the survival percentage, the percentage of callus, developed the bud and the number of leaves of eggplant. Callus in eggplant explants as a way of avoiding drought stress.

Abstract

Induction of in vitro sugarcane through somatic embryogenesis technique influenced by addition of plant growth regulator. The objective of this research was to determine appropriate formulation medium for indirect somatic embryogenesis induction on two potential sugarcane SUT Event 02 and PS 881. This research carried out in three steps, callus induction, callus proliferation, and shoot regeneration. Explants taken from basal of in vitro plantlet one month SUT Event 02 and PS 881 resulted from shoot regeneration previously. Five different medium formulas applied for callus induction and one formula for proliferation and shoot regeneration. Research using completely randomized design (CRD) factorial with five different formulation induction mediums. The result showed that the best respond of indirect somatic embryogenesis on SUT Event 02 and PS 881 was medium containing  3 mgL-1of  2,4-D.

Abstract

An invesgation about size and colour of Marchantia sp moss, had been done in Cughup Embun water fall, Pagar Alam, South Sumatera, Indonesia at November 9th, 2014(end of drough season). The aim was to know wether the distance from water fall (air and soil moisture) should effect the size and colour of those moss. Twenty meters sistematically distance in 4 points location  from above slope to water fall pond; 5, 25, 45, 65 and 85 m were considered for Marchantia sp sampling. Body size, colour and existing of Sporangium were noted. It is found that the size of moss body gradually bigger from 0.8, 1.0, 1.2, 1.3  and 1.3 cm. Colour of moss change An from pale brown, pale green, green and deep green. Amount  of archegoniopore seems exist in many number at 45 m distance from above ground.Keywords: Marchantia sp, moisture, archegoniopore, antheridiopore.
