<![CDATA[One of zoogeographic provinces of freshwater fish in New Guinea is Southern Province, which almost the same size as Northern Province. This region has high diversity of freshwater fish and also shared 33 species with northern Australia due to land connection in the past. Some endemicity areas with high conservation value are found in this region. The research aims is documenting freshwater fish diversity and its distribution in Southern Papua regencies: Boven Digoel, Mappi, Merauke and Timika. It had been conducted from July to November 2016. Purposive sampling method was used on this research. The fish samples were collected with active method using seine net and those collected with passive method was using gill netts. Fifty species, which consist of 44 natives and 6 introduced species that are part of 29 families and 39 genera were recorded in Timika, Asmat, Boven Digoel, Mappi and Merauke. There was no any dominant fish family found in the survey. Most species found during the survey (60%) has distributed in South New Guinea and Northern Australia. Six (6) introduced species were found spreading in several locations in Southern Papua. Freshwater fish richness in South of Papua and its restricted distribution in the area have showed high conservation value of the area, which should be well managed to avoid fish extinction. Key words: native, endemic, introduced, freshwater fish, South of New Guinea]]>

<![CDATA[Glucanolitic bacteria are bacteria that have the ability to break down glucan into glucose monomer units. The ability of the bacteria is caused by the presence of glucanase enzymes. The choice of glucanase derived from bacteria is based on the ability and speed of bacterial growth in terms of producing glucanase enzymes. The presence of bacteria and protozoa in the digestive tract symbiotic with each other to digest cellulose or concomitant materials . Based on the ability of the way of life to digest forage and leaf litter, it is suspected that snails (Achatina fulica) have the ability to produce glucanase biocatalysts, especially in the digestive tract. To find out the characteristics and characteristics of indigenous bacteria snail canals, identification of KE-B6 bacteria is carried out molecularly so that accurate and accurate results are obtained. The Basic Alignment Search Tools BLAST results of KE-B6 bacterial isolates based on 16S rDNA sequence data with 27F (Forward) and 1492R (Reverse) primers showed that these bacterial isolates had homology of 99.64% to Serratia marcescens. Key words: bacteria, glucanolitic, A. fulica, Serratia marcescens.]]>

<![CDATA[The availability of superior sugarcane varieties is one of the causes of the low national sugarcane production. The results of mutations from Bululawang sugarcane (BL) variety obtained three genotypes that have the potential to have high yields. Sugarcane plants can be cultivated in all locations because sugarcane can be grown in tropical and subtropical areas with the main problem of water availability being either shortage (drought) or excess (poor drainage). Increases and differences in sugarcane yields can be caused by fertilization, good water distribution throughout the sugarcane growth cycle, crop management, climate and different varieties. if the plant does not experience a lack of water, its production can reach 123 ton/ha/year, but if the plant is under moderate stress (4-5 weeks without rain) then the production will drop to 108 Ton/ha/year. Therefore, it is necessary to conduct a study to determine the potential of each mutant sugarcane at different locations. This research uses direct observation method to each location. Then the data obtained was analyzed descriptively analytically to provide an overview of the object under study through the data that has been collected as it is without analyzing and making conclusions that apply to the public. The results of the research that the M1 mutant sugarcane had the age of emergence of tillers, the highest number of tillers and was able to adapt very well at an altitude of ± 512 meters above sea level. The M1 mutant sugarcane has the highest plant height, the highest number of segments and is able to adapt very well at an altitude of ±62 meters above sea level. The M2 mutant sugarcane has the highest internode length and is able to adapt very well at an altitude of ±62 meters above sea level. Sugarcane M3 has the stem diameter, the highest internode length and is able to adapt very well to an altitude of ± 512 m asl.Key words: sugarcane; production; mutation; different varieties]]>

<![CDATA[Sowang (Xanthostemon novaguineense Valet.) is an endemic plant of Cycloops and strictly distributed. Since years, the population of the plants is threatened by human activities through land conversion, forest burning and logging. There are only few seedling grow in Cycloops naturally. Sowang wood is known as a good quality, because of its inherent hardness and high density. Scienfific information about this species is remain unclear. Regarding the plant regeneration, it is also not enough information so far. The study was conducted at three places around Cycloops areas namely Waena, Doyo Baru (sowing habitat) dan Wambena (no sowang areas) of Jayapura Regency, Papua and also greenhouse of FMIPA Cenderawasih University. The experimental units were set up in a completely randomized design with 3 treatments. Each experiment was carried out in three replicated and each replicate includes 100 seeds. Data were analyzed by analysis of variance (ANOVA), followed by LSD α=0.05. The result showed that there is no relation between geographical distribution of Sowang at Cycloops and the phisical and chemical soil. All type of soil used in this study was good as media of the seed germination. Regarding the ratio of the sapling population, the germination is still low only 18%, the seedling only survive for 38 days after sowing. Key words: Cycloops, regeneration, Sowang, Papua.]]>

<![CDATA[Frugivorous birds or avian frugivores play important role in seed dispersal cycle and forest regeneration in forest ecosystem of Papua. Despite the high diversity of avian frugivores dwelling in Papuan rainforest, and the fact that this region faces alarming rate of forest disturbance, little is known of their current presence in the lowland forest habitat. We surveyed the variety of frugivorous birds in three different habitats of lowland forest in Cyclop Mountains Nature Reserve and Nimbokrang District. The methods used were line and point transects and identification was done during the survey. A total of 36 frugivorous birds from eight families was found in both sites. There were 33 species of 8 families in Nimbokrang forest and 16 species of 7 families were encountered in the Nature Reserve. The primary forest has high diversity of frugivorous birds compared to that in secondary forest and forest garden. It was found that several species of Family Columbidae such as Macropygia amboinensis, Ducula pinon dan Reindwaedtoena reinwardtii moved and foraged along the forest edge and also visited degraded areas that still provided vegetation trees and perches. These findings might have importance for forest management and reforestation programmes in Papuan lowland forest.Key words: Frugivorous birds, diversity, lowland forest, Mountain Cyclops Nature Reserve, Nimbokrang.]]>
