Abstract

As one of the most important crops in Indonesia, sugarcane productivity is currently still hampered by Sugarcane Streak Mosaic Virus (SCSMV), with the intensity of leaf damage reach 60% . The symptoms of this disease are the occurrence of irregular pattern between light green to pale in sugarcane leaves.  The information about SCSMV in plant anatomy and physiology was still lacking. Therefore the objective of this studies was to determine the effect of SCSMV infection to morphological, anatomical and physiological characters of sugarcane leaves. The research was performed on 30 sugarcane clones by using a randomized block design with three replications. The results showed that there was change in the morphology of leaves, but leaf color did change. The decrease in the ratio of chlorophyll a / b leaves 65% higher in the resistant clones, i.e. clones PS 06 103 and PS 06 199. The number of stomata also decreased in clones by SCSMV.

Abstract

Rubiaceae is a cosmopolitan family of flowering plants distributed at almost all over the world. This family consists of 611 genera and 13,500 species. One of the 611 genera is Guettarda that has 50 to 160 species. Guettarda speciosa L. is one of species within Guettarda which is distributed from East Africa to the Pacific Islands including Indonesia. The objective of this study, therefore, was to determine the species’ distribution in Indonesia and its potential use. The data was collected from herbarium specimens deposited in Herbarium Bogoriense, field collection data from exploration by Center for Plant Conservation, Indonesian Institute of Sciences, and NKRI Expedition in West Papua. Based on the collected data, an analysis was conducted to create distribution map of the species. Information related to the potential use of this species in Indonesia showed thatit iscommonly used as ornamental plant, although Rumphius reported that in Ambon the wood or bark of this species was usually boiled together with root ofArtocarpus as a traditional medicine for diarrhea.

Abstract

Andamia heteroptera, known as rockskipper fish, is one of amphibious fish. Most of amphibious fish use caudal fin to facilitate locomotion in land and water. The modification is fusion of os hypural and reduction-fusion os epural and uroneurals. The aim of this study was to  acces skeleton and musculature structure of A. heteroptera caudal fin. Alizarin red-Alcian blue staining revealed that caudal fin of A. heteroptera has wider spina hemalis and spina neuralis support the locomotion. There is modification of caudal fin structure for support the locomotion. Caudal fin musculature of A. heteroptera is identified as primitive type, since its lack of musculus hypochordal longitudinalis.

Abstract

Plankton is one of water microorganisms that plays an important role as natural food for fish and shrimp and as an stability indicator of water or aquatic environment.The purpose of this study was to determine the composition and abundance of plankton in tiger shrimp ponds using concrete ponds without substrate, concrete ponds using sand substrate and ponds. Sampling of plankton and water quality was carried out from March to July 2016 at PunagaTakalar Experimental Pond at 6 ponds consisted of concrete ponds without 2 subplot of sand (pond A) and concrete pond with 2 subplate sand subplate (pond B) respectively measuring 1,000 m2 and a 2-square-meter plot of 2,500–3,000 m2 (pond C). The results showed that plankton abundance in pond A ranged from 37–349 individuals/L, pond B ranged from 35–1,399 individuals/L and pond C ranged from 54–999 individuals/L. The most common phytoplankton genera in this study was Oscillatoria while for zooplankton is of  Acartia.  The diversity of plankton in ponds A, B and C is included in the community of unstable to moderate biota. In general, the diversity of plankton in pond B is included in the community of moderate biota. The plankton uniformity index in pond A, pond B and pond C is generally close to 1 this indicates that the existence of plankton species in the three ponds is relatively even.

Abstract

Genetic improvement in the establishment of a rapid growth strain of Nile tilapia might be achieved through selective breeding program This research was aimed to estimate heritability and response selection of nile tilapia in brackishwater pond. Breeding  activity was carried out in fresh water in hapa 2x1x1 m. Males and females were breeding in pairs with a ratio of 1: 1. The number of established families was 19 families of 50 broodstock pairs. Harvesting of larvae was done on day 14. Larvae were collected and then kept in net 2 x 2 x1 m  with stocking density 125 fish/m2 for 60 days. The next stage was sexing  by grouping the male and female populations in each family. Grow out was carried out in net cage (3 x 5 x1.5 m ) that were placed in brackiswater pond at salinity 25–30 g/L with density 10 fish/m2.  Selection of broodstock in the male and female populations was done on weight of 250–300 g. Cut off selection was determined on weight from 316 to 382g (male) and 221–315 g (female). The results of this study showed that the estimation value for heritability of male and female were 0.42 ± 0.22 and 0.42 ± 0.23 and the estimation value for response selection were 10.66% (male) and 10.92% (female).

Abstract

Anabas testudineus Bloch, 1792 is economically important fish species found in Lubuk Lampam floodplains of Musi River. Fishing activities that take place throughout the year can affect reproduction patterns and recruitment (new additions) of fish. This study aims to evaluate several parameters of betok fish populations that can be used as input for fish resource management policies in floodplains of Musi river. A total of 3271 samples of betok fish caught by fishermen from March to November 2011 were collected to obtain data on fish length and weight. Growth parameters (L∞, K, Z dan M) were calculated using FiSAT II based on the length frequency distribution of fish. The values of L∞ and K were obtained at 204.75 mm and 0.24 / year respectively while the maximum age of fish was estimated to be 4.36 years. The total mortality (Z) and natural mortality (M) of betok fish is 0.99 / year and 0.42 / year, Fishing mortality (0.56/year). The exploitation rate (0.57) was slightly lower than the predicted value (Emax= 0.69) indicating that Anabas  testudineus was near fully exploited in the Lubuk Lampam floodplain ecosystem.

Abstract

Survival rate of coral trout seed produced from aquaculture was relatively low. In 2015, high mortality was found at the early stage of larval development (<D10), approximately 64.37 % of the total production. There has been no standard management for coral trout (Plectropomus leopardus) larval rearing, which was used to adopt management for grouper (Epinephelus spp.) larval rearing. This study was to apply suitable management for coral trout larval rearing into aimed to decrase mortality at early stage larval development and to increase survival rate. There were two different managements in this study: A. applying the results of previous research of coral trout larval rearing from 2004 to 2015, and B. using standard management for grouper larval rearing. The results showed that management A was more suitable management for coral trout larval rearing compared to management B. Management A resulted in the increasing of survival rate by five times (p=0.0056) and of growth rate at early stage by 1.15 times (p=0.2338) higher than those of management B.
