Abstract

Heavy metal bioconcentration was examined and evaluated in the muscle of several of freshwater fishes species collected from a complex of some oxbow lakes in Kahayan River and from Lake Sembuluh, Central Kalimantan. The objective of the study was to find natural background values of heavy metals in water, sediment and its biomultiplication factor related to their concentration in water and the fish position in the foodweb. In this analysis,one to twenty-five grams of fish muscle samples was obtained from the posterior part of pectoral but anterior to anal fins. Water samples, which were taken from surface and bottom layers of the lakes, were mix and preserved with nitric acid. Sediment samples were obtained by using Ekman Grab and the interstitial waters were extracted by using wet digestion technique.Iron concentration in fish muscle is the highest in omnivorous, followed by that of in carnivorous and detritivorous fish. Manganese, lead and mercury had different pattern of bioconcentration levels. Bioaccumulation factor for each metal and at each food habit category was also variable; the lowest value of 0.7 for iron in second consumer and 28.2 for mercury in primary consumer. Mechanism of heavy metal intrusion to fish muscle is very intricate and apparently depends upon feeding habit of each species. Concentration of mercury in water and fish muscle was far above minimum risk level, but concentrations of iron, manganese and lead in water and fish was considered still safe for environment as well as for human health. Potential utilization of these results as evaluation criteria for fishery reserve is discussed.

Abstract

Pigs have an important role in the ecology of influenza virus since they are sensitive to influenza viruses from human and avian origin. Influenza A virus has a host specificity, although not absolute, so most of the AI virus circulating in various species is only limited to the species, but sometimes there are interactions between different AI virus species or strain. Farming systems that combine a variety of animal species together in the same or around the sites have an important role in the spread of disease and transmission between species. This study is aimed to investigate the cycle of AI virus in order to determine the potential occurrence of viral transmission among species pig and bird at the pig farm that also raising poultry. Influenza virus was identified by methods of RT-PCR and qRT-PCR. The results showed that the novel H1N1 pandemic virus was detected in one pig farm in Tangerang (Banten Province). The AI/H5 virus is also detected in the pig farm that also raises poultry or poultry/pig farmers and located adjacent each other. The AI virus / influence A is also detected in most of the pigs. Detection of AI viruses that infected in pig farm which kept birds or poultry farm around the pigs farm had potential of AI virus transmission from birds species to pig or vise versa. The pigs could serve as a mixing vessel, thus providing opportunities likelihood of reassortant viruses.

Abstract

A gillnet is a common fishing gear for exploitation and fish capture at Jatiluhur Reservoir. The fish size captured by the gillnet depends on the mesh size for its selective fishing gear. Determination of gillnet mesh size is one of effort for fisheries management.  The management of nile tilapia (Oreochromis niloticus) is based on gillnet selectivity and reproductive biology of nile tilapia. The aim of the research was to estimate length at the first mature (Lm) and gillnet selectivity for nile tilapia. The research was conducted at February-September 2017 through experimental fishing using gillnet with 1.0–4.0 mesh size (interval 0.5 inch). The gillnet installation was performed at six stations, namely Cihuni-Cibadak, Sungai Cikanyayan, Sungai Ciririp, Sungai Cihonje, Pasir Kole and Cilalawi. The Lm of nile tilapia was 18.3 and 23.3 cm for female and male, respectively. The total length retained in the gillnet with the highest probability for mesh size 1.0; 1.5; 2.0; 2.5; 3.0; 3.5 and 4.0 inches were 9.5; 12.5; 14.5; 18.5; 20.5; 26.5 and 30.5 cm, respectively. The minimum mesh size used for nile tilapia exploitation was ≥3 inches because it was able to catch nile tilapia with the total length larger than Lm (Lc>Lm) and with an SPR value of > 40% so that the tilapia resource in the Jatiluhur Reservoir remains sustainable.

Abstract

The fish research in Indonesian waters has been begun since 16 century ago. Most of the research collected fish around Batavia.Many new species was described and the type specimens deposited at the museums in Europe or America.The study of fish diversity and the lost of fish species was conducted at River Ciliwung and R. Cisadane in 2009. The aim of this study is to describe the recent fish diversity in both river drainages, then make a comparison with the number of species recorded based on the references data.The differences between the two datas show the number of species lost. The result of the study showed a total of 20 species of 13 families were collected in R. Ciliwung, while from the references data there were about 187 species, so the fish diversity lost in the Ciliwung river about 92.5%. The fish research in R. Cisadane were collected 39 fish species of 24 families. There were 135 species of 38 families of the references data, so the fish diversity lost in R. Cisadane is about 75.6%.

Abstract

Dendrobium merupakan marga yang memiliki banyak jenis asli Indonesia dan yang berpotensi ekonomi.Dendrobium schulleri J.J.S. misalnya mempunyai sifat-sifat yang menarik yang perlu diperhatikan untuk dikembangkan lebih lanjut.Seperti diketahui, perbanyakan anggrek dapat dilakukan melalui biji.Secara ini diperoleh bibit yang banyak.Tetapi perbanyakan demikian memerlukan pengetahuan mengenai medium yang cocok untuk menyemaikan biji tersebut dan memeliharanya sampai siap ditanam. Saat ini medium yang cocok untuk D. schulleri belum diketahui. Sehubungan dengan medium untuk menyebarkan biji anggrek, Pages (1971) menambahkan homogenate pisang pada medium Knudson C yang menggunakan bahan-bahan kimia untuk Dendrobium dan Phalaenopsis. Menurut Ochse (1931) buah kultivar-kultivar pisang di Indonesia memiliki sifat-sifat yangberlainan; komposisi kimianya juga berbeda (Direktorat Gizi 1972).Perbedaan ini mungkin dapat memberikan pengaruh pada perkecambahan biji dan pertumbuhan semai anggrek. Untuk itu beberapa pisang yang terdapat di pasar dicoba untuk menumbuhkan biji-biji anggrek D. schulleri.Berbeda dengan Pages (1971) pada penelitian medium pindahan ini hanya digunakan pisang, agar, gula pasir dan air suling tanpa menggunakan Iain-lain bahan kimia seperti pada medium Knudson C.

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.
