Digoel river have an important role to the human activity and environment in Boven Digoel Regency. Increasing of human and industrial activity around the watershed of Digoel River were suspecious to cause the degradation water quality in Digoel River. This research was done to monitor the impact of the industrial activity to the quality of water in outlet of waste water treatment plant(WWTP) of PT. Korindo to the water quality of Digoel River. Parameter analised are the physical, chemical, organic chemical, microbiology and metal content in water. Analysis of the water quality accordance to PP Nomor 82 Tahun 2001 about water quality managementand water pollution and Permen LH Nomor 5 tahun 2014 about the quality of waste water.The monitoring was conducted in three months at five sampling stasion (river upstream, river down stream, outlet WWTP plywood, outlet WWT workshop, outlet WWTP palm oil) in Districk Jair. The rsult showed, parameter of BOD, COD, phospate, phenol and total coliform in Digoel River exceeded class I of water quality standards. Outlet of plywood WWTP have two parameters that exceed the quality standard which were TSS 15.67 mg/L and phenol 13.33 mg/L.The outlet of WWTP workshop have four pameter exceeded the quality standard which were TSS (383.67 mg/L), oil/fats (502.0 µg/L), phenol (11.0 µg/L), and zinc (21,000 mg/L). IPAL oil WWTP outlet have two parameter sexceeded the quality standars which were oil/fats (313.0 µg/L) and total coliform (> 979 cells/100 mL). The result indicating that the status of water quality of Digoel River are categorized as “lightly polluted”. Therefore based on utilization, it was categorized as class IV water quality that can be used for irrigating, planting and other purposed that meet the requairement of water qualiy in this class, while for other uses need necessary processing. In order not to increase the pollution in the Digoel river the WWTP of industry around Digoel River should improved their treatment, so that waste water discharged to the Digoel River not exceed the stanards quality.Key words: water quality, digoel river, status of water quality, pollutant index.

Jayapura Regency is one of the regions that considerable potential for economic growth from non-timber forest products. In the development of non-timber forest products in the form of products produced by insects, silk yarn is one of the commodity that has a high demand. The domestic demand for silk yarn is 900 tons/year, while only 19.05 tons/year were produced in 2012. Jayapura Regency has a great potential to supply the shortage of cocoon for the domestic market and the wide open international market. Related to this challenge, this study conducted basic research on the diversity of moths from the Bombicoidea superfamily in the natural forest of Kampung Soaib, Jayapura Regency. Sampling using light traps, four species of moths from the Saturnidae family were obtained, Syntherata apicalis, Opodiphtera intermedia, Opodiphtera papuana, and Coscinocera hercules. The cocoon of Coscinocera hercules is very potential as a silk thread producer because it is large and consists of two layers with brown color and has fiber characteristics similar to the cocoon of Attacus atlas which has been developed as a wild silk producer. These results indicate that the lowland forests of Jayapura Regency as a habitat for wild silkworm species has potential to be developed as non-timber forest products.Key words: Superfamily Bombicoidea; silkworm; cocoon; Jayapura regency

Pendugaan Densitas Karbon Pada Tegakan Pohon di Kawasan Hutan Kampung Sawesuma, Distrik Unurum Guay, Kabupaten Jayapura Ziyadatun Ni'mah; Rosye H.R. Tanjung; Hendra K. Maury

The community managed conservation area forest (AKKM) of Kampung Sawesuma is part of the lowland forest landscape of Northern Papua. Lowland forests have a very high diversity of plant species and act as carbon sinks stored in tree stands. To determine the amount of carbon stored in tree stands, an estimation of the carbon density of tree stands was carried out in the AKKM forest area of Kampung Sawesuma, Jayapura. Estimation of carbon density was carried out by non-destructive method of tree stands using sample plots (measurement transects) and calculating tree biomass using allometric equations. The measurement results show that the tree biomass in the AKKM forest area is 167.5 tons/ha with an estimated carbon density of 78.7 tons/ha in the stands. Key words: carbon density; lowland forest; Sawesuma Village.

Ornitophera sp. is one of the groups of butterflies endemic in Papua and West Papua provinces. The significant morphological differences between male and female butterflies (dimorphism) are in the shape, size and color of the wings. Morphological characteristics are important sources of information. Based on the results of specimen collections at the Papua Insect Collection Laboratory (KSP) Jayapura, there are several species from various locations in Papua. The variation in dimorphism is likely to occur in this species which gives rise to new sub-species. The purpose of this study was to record the dimorphism of the endemic Bird Wing of Papua which had been stored in the Papua Insect Collection Laboratory (KSP) Jayapura. The method used is a direct measurement of the morphology of bird wing butterfly specimens stored in the KSP Laboratory, Cenderawasih University. Morphometric data were analyzed using the SPSS 20 and Multi Variate Statistical Package (MVSP 3.1) programs. The results obtained were 7 Ornithoptera species stored in the KSP Jayapura Laboratory, namely O. chiamera, O. goliath, O. meridionalis, O. paradisea, O. priamus, O. thitonus and O. rothschildi. Based on observations there are striking differences in color, shape and size between male and female in the same species. Key words: birdwing butterfly, Ornithoptera sp., KSP Jayapura, dimorphisme.

This study is aimed to analyze the comparative quality of PMSA2 gene amplicon product stability from two different specimen sources, spot specimens of dried blood and venous blood, as well as selecting the best storage method for specimens of blood samples. This research uses descriptive laboratory research methods. The research began with the process of sample preparation for dried blood spot and venous blood, each using Whatman 903 paper and vacuum tubes containing EDTA, isolating genomic DNA using KIT Zymo Research, amplification of PMSA-2 genes with PCR, detection of PCR products through electrophoresis, measurement of DNA concentration and absorbance, and data analysis. The results of this study are expected to be a source of information about the advantages of two specimen storage methods for clinical blood samples, as well as providing a clear description of the quality of each specimen storage method based on the quality of its amplicon products. The results showed that a total of ten medical samples of dried blood spot and ten venous blood were isolated from the genomic DNA of ten and nine, respectively. PMSA2 gene amplicons detected were seven in venous blood and six in dried blood spot. Venous blood specimens have sensitivity in detecting PMSA genes in samples with the highest value of 554 ng / μL and purity of 2,007 (WB7), and concentration of 550.2 and highest purity of 2,076 (WB10). Venous blood storage techniques using categorized vacuum tubes are effective in the detection of PMSA2 genes and have time efficiency in the process. From these results it was also concluded that the comparison analysis of amplicon products between venous blood specimens was better, more stable and efficient than dry blood spot specimens, thus recommending storage of venous blood specimens using vacuum tubes as the best storage method of blood sample specimens.
