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.

Abstract

The research on the effect of architectural tree model to the noise level of motor vehicles on Demang Lebar Daun Street Palembang has been conducted. The purpose of this study was to analyze kind of architectural tree model can reduce the highest noise levels among the architectural tree models encountered and identify the architectural tree model. The method used was purposive sampling. Measurement of the noise level and architectural models were selected according to the type of the tree encountered on the left or right side of the street. The noise level measurement during the daylight was carried out simultaneously at a point of 1 meter in front of the tree, 1 and 5 meters behind the tree,for 10 minutes with the readings for every 5 seconds at 07:00, 10:00, 15:00 and 20:00. The results showed that The architectural model of Switenia magahoni tree was Rauh model, Lagerstroemia sp. tree was Troll model and Thyrsostachys siamensis tree was McClure model. The highest noise level reduction was from bamboo tree, respectively by 4,88 dB (A) and 8,52 dB (A) at the distances of 1 and 5 m. Keywords: noise level, reduction, architectural tree model

Abstract

A rapid bird survey was done in a small conservation area of industrial timber concession of PT BMH (Bumi Mekar Hijau), namely KPPN (Kawasan Pelestarian Plasma Nutfah), South Sumatra Province. The area has 448 ha, dominated by degraded secondary swamp forest surrounded by Acacia plantation. Three survey methods were applied to assess bird diversity in this area: transect line, mist-netting and audio-visual station recording. A total of 36 species was recorded during survey. Among three methods applied, transect line is the most effective method to detect more bird species (29 species), followed by audio-visual station recording (26 species) and mist-netting (three species). There are eight species which protected by Indonesian law and two birds are listed as Near Threatened (NT) by International Union for Conservation of Nature or IUCN. Although number of species birds recorded are not significance, but this area still support habitat for various birds diversity, and the forest remaining should be well-managed to support its conservation goals.

Abstract

An observation about beach crab (Scopimera sp) population, their feeding behaviour and predator bird had been done at October 9 th, 2014 in Pantai Pasir Padi, Eastern Bangka Island beach, near Pangkal Pinang town. Ten 1 meter square plots were put at sandy beach and number of Scopimera sp be counted by the number of their hole nest home. Their feeding behaviour observed directly by eye-watching and video making. The threatening of bird predator was noted too.  The investigation find out that the mean of crabs population is 17 individu/m2 .  They come out from home hole for feeding around by sieving wet sand that be taken by front legs, obsorb organic nutrious material by mouth and kick residual sand to behind legs, move it as a small sand ball to right of left back side.  Production of small ball sand were about 15 - 30 balls /per minute. For making the nest hole, bigger sand ball were produced about 7 – 9 ball/minute; ball colour is same with under layer beach sand; quite grey. The crabs run instinctivey fast, when the threat come from their natural enemy, predator bird, Actitis hypoleucos.  Bird searching behaviour look adapted to the fast run of crab.

Abstract

Odonata is considered an environmental indicator group of freshwater habitats. Thus there is a need to have a good baseline data to use it for monitoring fluvial habitats. However, species composition of Odonata in Kota Waringin Village is poorly known.This study aims to determine the diversity of dragonfly species in the Kota Waringin Village, Puding Besar District – Bangka Island. Data were collected at Three different ecosystems in Kota Waringin Village area (River in Forest, River in oil palm plantations and yard). Location for data collection based on the availability of water resources using purposive sampling method. The species were identified using identification books (Dragonfly of Singapore and Australian Dragonfly). Based on research we revealed 13 species of dragonflies are exist in three sampling locations (Agrionoptera insignis, Brachydiplax chalybea, Heliaeschna crassa, Ictinogomphus decoratus melaenops, Nannophya pygmaea, Neurothemis fluctuans, Neurothemis ramburii, Neurothemis terminata, Orthetrum chrysis, Orthetrum Sabina, Rhodothemis rufa, Zyxomma petiolatum and Rhyothemis phyllis). Keywords       :  Odonata, Dragonflies, Inventory, Conservation, Bangka Island

Abstract

Research on Diversity and distribution of butterflies, was held at the Campus Indralaya Sriwijaya University of South Sumatra. The purpose of this study was to obtain information species diversity of butterflies at the Sriwijaya University of Inderalaya and distribution of species of butterflies in several different habitat types in the campus area Unsri Indralaya. The study used purposive and collection methods in November 2014-january 2015. Sampling sites were divided into five locations: Arboretum, Science Faculty, Faculty of Law, Faculty of Agriculture and Swamp Cape Disconnect. The parameters used are the index of species diversity, dominance index, and evenness index. The results showed that the diversity of butterflies in the region is classified as moderate. Overall found as many as 40 species of butterflies with a number of 609 individuals consisting of 5 the Papilionidae, Nymphalidae, Pieridae, Lycaenidae, and Hesperiidae. Regions Sriwijaya University has a diversity of butterflies that were moderate with criteria (H'1≤H'≤3), in each different habitat types, and not found butterfly species that dominate in every type of habitat in this Unsri region. Distribution of butterflies found in the campus area Unsri Indralaya categorized fairly evenly with a range of values from 0.58 to 0.68.Keywords: Butterflies,  Diversity,  Distribution , Sriwijaya University of Indralaya
