Traditional market is a potential source of the spread of avian influenza virus. This research is aimed to determine the prevalence of avian influenza virus (AIV) subtype H5N1 on poultry sold in traditional market in Semarang City. Fifty-five poultry samples sold in six traditional markets in Semarang City; i.e. Karangayu market, Mangkang market, Gunungpati market, Rejomulyo market, Gayamsari market and Karimata market taken from its cloaca swab. Further, cloacal swab samples grown in pathogen-free chicken embryos aged nine days. Then, it incubated for four days at 37 °C. Allantoic fluid then collected and tested to agglutinate red blood cells. RNA extracted from the samples showed haemagglutination activity. Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) applied to identify the subtype of AIV using the specific primer H5 and N1. The PCR product resulted from RT-PCR then visualized using electrophoresis. The results showed that four AIV subtype H5N1 isolates have successfully isolated from cloacal swab samples (7.27%) with the distribution of 2 isolates were from Mangkang Market (28.57%), 1 isolate was from Rejomulyo Market (7.69%) and 1 isolate was from Karimata Market. The prevalence of AIV subtype H5N1 was 28.57% in Mangkang market, 7.69% in Rejomulyo market and 9.09% in Karimata market. The prevalence values of each species were 7.89% in chicken and 9.09% in the wild duck. According to this result, poultry sold in traditional market in Semarang have a potential source of AIV subtype H5N1.

Salinity resistance level on soybean which influenced by its genotype is important to be explored.One of the important factors which determine the success of soybean cultivation on saline soil or salt-affected soil is salinity resistance level. Eleven variants or genotypes of soybean were collected from Indonesian Legumes and Tuber Crops Research Institute and were tested on four different electrical conductivity level of soil (0.5 dS/; 5.8 dS/m; 8.4 dS/m; and 12.2 dS/m). Soybeans were planted on pot in green house. Salinity stress will started when plants were on 21 days after planting (DAP). The treatment was watering using some different concentration of sea water for 30 days. Three methodswhich used to determine salinity resistance level of soybean were seed yield reduction level, stress susceptibility index (SSI), and leaf scorch score. Soybean will classified into salinity tolerant genotype group when weight reduction of seed was <66%, leaf scorch score was <2.0 and SSI was <0.95. Results showed that genotypes with 0.5-5.8 dS/mof soil electrical conductivity tolerance were: Wilis, Tanggamus, Gema, LK/3474-403, MLG 3474-991, IAC100/Burangrang//Malabar-10-KP-30-75, MLG 2805-962; genotypes with8.4 dS/m of soil electrical conductivity tolerance were SU-7-1014 and Argomulyo//IAC100-10-KP-40-120; and genotypes with 12.2 dS/m of soil electrical conductivity tolerance were IAC100/Burangrang//Malabar-10-KP-21-50 and Argopuro//IAC100. These results can be used by soybean breeder as a reference in improving salinity resistance level of soybean for further study as anticipation of salt affected soil wide spread.

Green sea turtle (C. mydas) is one of TSD (Temperature-dependent Sex Determination, TSD) animals which mean that their sex is determined by the egg’s incubation temperature. Genotypic Sex Determination (GSD) homologous genes play a role in TSD process. Until now, research on the pattern of sex determination genes in C.mydas has not been conducted yet. The aim of this research is to reveal sex determination and differentiation genes expression in Mesonephros-Gonad (MG) complexes of C. mydas embryos which incubated in masculinizing temperature (MT) and feminizing temperature (FT). C. mydas eggs were incubated in 3 different stage of TSP (Thermosensitive Period) at masculinizing temperature (26±10C, MT) and feminizing temperature (31±10C FT). Mesonefros-gonad complexes were isolated at Pre-TSP stage (FT at 14th day, MT at 24th day), TSP stage (FT at 24th day, MT at 36th day) and differentiated stage (FT at 40th day, MT at 58th day). RNA from mesonephros-gonad (MG) complexes were converted into cDNA by RT-PCR process. Pattern of Sf1, Wt1, Aromatase, FoxL2, Sox9, Wnt4, Fgf9 and Rspo1 genes expression were analyzed by quantitative Real Time PCR (qPCR) method with β-actin gene as an internal control. Result of this study shown that expression pattern of Sf1, Wt1, Aromatase, FoxL2, Sox9, Wnt4, Fgf9, and Rspo1genes in gonadal embryo of C. mydas were increased during gonadal development stage. Four genes expression patterns (Wnt4, Fgf9, Rspo1, and FoxL2) have shown that these genes have role in sexual differentiation rather than in sexual determination.

Kenaf is a plant fibre with high potential as source of material industry. Originally, kenaf usage in Indonesia is still limited only for jute sacks material, which is then displaced by plastic sacks production. While at international scale, kenaf has been started to be developed as pulp material, polypropylene composite, fibreglass replacement, and particle board for automotive industry materials. Indonesia is a tropical country this condition which suitable for kenaf cultivation. However, research reports about kenaf potential usages are still few and limited in domestic level only. Whereas, Indonesian kenaf plant information is needed by international community to understand comprehensively about the potential of tropical plants. This article aims to provide an overview about kenaf cultivation potential and usages in Indonesia as well as the possibility of future development.

Tobacco variants in Indonesia are very diverse which can be identified from their morphology or their characteristics. This is related to tobacco long adaptation in different agro ecology of plantation areas which spread out at 15 provinces, from dry to irrigated land and from low land to high land areas. Tobacco has been introduced in Indonesia for more than four centuries and mostly used as cigarette. This commodity and its products are still economi-cally important for government and farmer income. It contributes in government income which reached up to 114 trillion rupiahs and farmer income up to 70% in 2014. Tobacco diversity in Indonesia can be grouped according to their growing season and their usage in cigarette blending. Tobaccos which grown at the end of wet season and harvested in dry season are called Voor Oogst tobaccos, otherwise tobaccos which grown at dry season and harvested in wet season are called Na Oogst tobaccos. Based on their usage, tobaccos are categorized as main ingredients for kretek cigarette, Rolled Your Own (RYO) cigarette, and cigar industries.

Fish is the main source of ω-3 long chain polyunsaturated fatty acids (LC-PUFA) such as eicosapentaenoic acid (EPA, 20:5ω-3) and docosahexaenoic acid (DHA, 22:5ω-3), which have positive effects on human health and can be beneficial in human diet context. Studies involving fatty acyl desaturase (Fads) and elongase of very long chain fatty acids (Elovl) enzymes that convert C18 PUFA to C20/22 LC-PUFA have been performed in some fish species. However, very little is known about LC-PUFA biosynthesis in tuna species. This study investigated the Δ6 Fads gene performance in the SBT cell line. The Δ6 Fads nucleotide sequences from various fish species were identified and retrieved to compare them with the SBT Δ6 Fads nucleotide sequence. The Δ6 Fads gene was performed using real time PCR (RT-PCR) and then was compared it with β-actin gene performance as a reference housekeeping gene. By performing multiple sequence alignments and comparing the highly conserved regions among fish Δ6 Fads sequences, the SBT Δ6 Fads nucleotide sequence was determined to be ≥ 75% identical to the other fish Δ6 Fads sequences. The results showed that when the SBT Δ6 Fads and β-actin cDNAs were performed in a standard PCR system and the products were analysed by electrophoresing them on a 2% (w/v) agarose gel, the target genes that were obtained were similar to the expected sizes. The observed band size for the Δ6 Fads PCR product was 207 bp and for the β-actin PCR product was 98 bp. The presence of the observed bands indicated that the primer pairs that were designed and used were successfully amplified the target genes. The results of this study might provide relevant information to support further investigating of the desaturase and elongase gene expression that might contribute to a better understanding of ω-3 LC-PUFA biosynthesis in fish.

The composition and density of vegetation in the mangrove areas affected soil conditions. Areas with a smooth distribution of substrat particles contain higher organic matter, and is characterized by the growth of mangrove better and more diverse. How environmental conditions affect the distribution of mangrove substrats observed in this study. The study was conducted in the area of Sungai Barong Kecil and Sungai Barong Besar which is part of the Sembilang National Park, Banyuasin District, South Sumatra. The study was conducted in May and June 2014. Location determined substrats by purposive sampling with particular consideration, and samples were taken using a modified PVC pipe at a depth of 10-30 cm, while the checkered line method with parallel lines used for observation shoreline mangrove distribution. Physical parameters such as salinity environmental chemistry, pH, and moisture. Analysis was performed on substrat particle size, substrat organic matter content, as well as the condition and type of mangrove. The results showed that the Sungai Barong Kecil area tend to have a much smoother distribution of substrat particles (clay content and higher dust). This leads to more easily grow mangroves and mangrove species were found to be more diverse (Avicennia marina, Avicennia alba, Rhizophora mucronata and Avicennia officianalis). Avicennia marina is the dominant species that indicates that the species is highly adaptable to various environmental conditions.

The number of published reports of flower buds, anthers and on microspore culture of horticultural plants, especially in soybean is very low. The purpose of this research is to determine soybean microspores development stage based on the length of flower buds. Five local cultivars such as Argomulyo, Grobogan,Wilis, Anjasmoro and the black soybean Malika were used. Flower buds were the main material for microspore culture. Anjasmoro cultivar produces the highest number of flower bud. Anjasmoro soybean cultivar at third stage development, 3.1-3.6 mm length, was selected for microspore culture, based on plant height, length of anther, total of microspore per bud. Anjasmoro cultivar has the most late-uninucleate microspore and the total of shed of Anjasmoro microspore in the B medium with 340C for 4 day is 3820. Results revealed that Anjasmoro soybean cultivars had 354.67±59.67 μm length of anther, 2003±216 microspore per bud and the most mid and late-uninucleat microspore on 2.6-3.6 mm length flower bud. Anjasmoro soybean cultivar can be used for microspore culture.

In this study, we want to characterize egg white protein-tomato extract complex based on the UV-Vis spectrum. The formulation of antioxidant complex Non-Freeze-drying (NFD) was made at a ratio of 1:10 (v/v) while the Freeze-drying (FD) sample was made at a ratio of 1:2 (v/v). The results showed that the absorption peak of FD complex profile value was lower than the single ingredient, while the tomato extract was higher than the complex profile. On the contrary, the NFD complex showed a higher peak absorption value than to every single ingredient. Based on each UV-Vis spectrum profile, the tomato extract profile shifted the absorption peak, and the absorbance value of the FD sample was changing higher than the NFD sample, while the egg white protein spectrum profile did not change significantly in the FD and NFD samples. The absorption peak of the complex is higher than the single ingredient indicated that the characterization of the complex had been formed. In the NFD complex profile, the absorption peaks formed at the wavelength regions of 230 nm and 280 nm with absorbance values of 2.51 and 0.76 and its number has higher than those of the FD complex with absorbance values of 2.47 and 1.82 at wavelengths of 220 and 265 nm.
