Snakehead gudgeon (Giuris margaritacea) or Payangka in Indonesianâ€™s local name, has a high population and been used as a consumption fish mainly by people around Lake Tondano, not only the consumption size, but also the juvenile (it called Nike) are preferred. The fish resources are the essential source and need to keep their sustainable in the future. The research was carried out in 2015. The study was aimed to identify and record some aspects of snakehead gudgeon fish biology in Lake Tondano Mi-nahasa Regency of North Sulawesi. Fish samples were obtained from fisher's catch. The morphometric and meristic character was measured, and also was performed surgery to observe reproduction and food. The results showed that the growth pattern of Giuris margaritacea was positive allometric with sex ratio 1: 1.41. The fish was spawning whole year with fecundity between 36,892-90,102 eggs, and diameter of the egg was 0.285 mm on average. The size of the first mature female was 10.75 cm gonads. Snakehead gudgeon was a carnivorous fish with shrimp as the primary food, and the relative length of the digestive tract was 82.88%.

Characterization of native orchid (species) in Indonesia is important for preservation of germplasm and selection process to obtain dominant character of orchids as potential parental. Morphological characterization is a method to obtain scientific information in phenotypic manner. Characterization of plants was carried out on 10 native orchids of Dendrobium genus to obtain specific character. Characterization process based on UPOV guidebook and morphological observation of pollinia was also carried out on 10 native orchids to obtain information about the structure and physiology of pollinia. The results of morphological characterization on 10 native orchid showed several qualitative characters such as flowering position, cross section of leaf, pseudobulb firmness, and leaf arrangement in D. Canaliculatum was different from 9 other native orchid. Morphological pollen of 10 native orchid shows the diversity structure of pollinia and the physiological conditions of mature pollen which are ready to pollinate are pollinia with a golden yellow colored. Knowledge and information about parental relationships is the main point for developing ornamental plant breeding programs. Selection of native orchids as potential elder is important where selected elders will be used as a source of genetic diversity. The results of this study are expected to provide scientific information and phenotypic selection for the development of hybrid orchids.

The Sumatran Striped Rabbit (Nesolagus netscheri ) is Â a naturally rare, which is a protected animal based on Government Regulation Number 7 of 1999 and renewal of Permen LHK No. P.106 which are categorized as Data DeficientÂ by the IUCN (International Union of Conservation of Nature) since 2019. Samples were obtained from Pagar Alam, South Sumatra. Most commonly found at elevationsÂ above 600 m in montane and sub-montane primary habitat. Molecular genetic characterization of sumatran striped rabbit is to know genetic information and genetic identification of N. netscheri. Primers 12S rRNA were used in this study to characterize Sumatran striped rabbit. A 1 band were detected ranged from 900 to 1000 bp. Molecular markers represent reliable tools which may have a great impact in rabbit breeding and genetic improvement of rabbits. Molecular markers on Nesolagus netscheri is expected to tools in the identification of Sumatran striped rabbits from South Sumatra.

Endophytic fungi are fungi which live inside the host plant tissue and have been undergone a horizontal gene transfer process. Endophytic fungi are able to synthesize the same bioactive compounds which synthesized by their host plants. The host plant used in this research was dragonâ€™s scales fern (Pyrrosia piloselloides (L.) M.G. Price). Dragonâ€™s scales fern produces various of bioactive compounds which used as antibacterial agents such as polyphenols. This research was aimed to obtain endophytic fungi isolates from trophophyll fronds and sporophyll fronds of dragonâ€™s scales fern, to determine the antibacterial activity of the secondary metabolite extracts of endophytic fungi, to determine the Minimum Inhibitory Concentration (MIC), to determine the characteristics of the endophytic fungi isolates which potentially as antibacterial source. Based on the research, 13 endophytic fungi isolates were obtained from dragonâ€™s scales fern fronds consist of 5 isolates from trophophyll fronds and 8 isolates from sporophyll fronds. The antibacterial activity test showed that the extract of secondary metabolites of the isolate DTP2 had the highest inhibition zone diameter against E.coli 14.82 Â± 4.05 mm, DTP4 against S.aureus 8.80 Â± 0.03 mm and DSP4 against S.dysentriae 10.15 Â± 0.36 mm. MIC of ethyl acetate extracts of secondary metabolites of isolate DTP2 against E.coli was 125 Âµg/mL, DTP4 against S.aureus was 125 Âµg/mL and DSP4 against S.dysentriae was 31.25 Âµg/mL. The endophytic fungi isolate DTP2 identified as Aureobasidium melanogenum, DTP4 identified as Penicillium alliisativi and DSP4 identified as Aspergillus flocculosus.

Twelve endophytic fungi were isolated from Jeruju plant. Three of which have the best antioxidant activity, namely Culvularia lunata DJS1, Diaporthe phaseolorum DJS2, and Colletotrichum siamense BJS4. The fungi can produce secondary metabolites that have the potential as antioxidant compounds. This study aims to isolate the antioxidant compound using a chromatography column and test the antioxidant activity using DPPH method. Isolation of secondary metabolites produced 40 eluates. The IC50 value of DJS111 and BJS42 eluates were 10.20 Âµg/ml and 20.89 Âµg/ml, which is an antioxidant compound with very strong activity. The IC50 value of DJS24 eluate was 54.45 Âµg/ml, which is strong antioxidant activity. DJS111 eluate has antioxidant activity that approaches to ascorbic acid as a standart antioxidant compound (7.76Âµg/ml). From TLC, DJS111 contains flavonoid compound and DJS24 and BJS42 contain terpenoid compound.

This study aims to determine the effect of leaf fertilizer on three nutrient efficient corn genotypes in tidal land. This research was coductedÂ in Village Mulia sari, Sub-district Tanjung Lago, District Banyuasin, South Sumatra in the noble village of Sari Tanjung Lago sub-district from August to December 2017. This study uses the Split Plot Design consisting of 3 factors, namely the first factor of genotype, the second factor is the dose of urea A0 = 0 kg, A1 = 250 kg, A2 = 300 kg and the third factor of leaf fertilizer consists of: P0 = (control without spraying), P1 = 30 days of spray, P2 = 45 days of spray, P3 = 30 + 45 days of spray, P4 = 60 days of spray, P5 = 75 days of spray, P6 = 60 + 75 days of spray. repeated three times. Observation results used of 300 kg of urea fertilizer and leaf fertilizer had a good influence on the growth of G3 corn genotypes and the production of corn plants in tidal land. The combination of giving 300 kg of urea fertilizer + leaf fertilizer gives a pretty good influence on the growth of G3 corn genotypes with a production of 7.44 Ton/hectares
