Abstract

The wildlife on earth is increasingly urged by human life, where forest functions are used as residential and agricultural land. Illegal logging causes destruction of habitat and excessive use of wildlife causing damage to ecological functions in general. Uncontrolled utilization of eggs and fowls of wattled brushturkeys will accelerate the extinction of these animals in natural habitats. On the other hand the dependence on protein and economic needs of communities in the Arfak Mountains is high as evidenced by the widespread of hunting activities conducted with various purposes of utilization. Breeding efforts for the purpose of utilization need to be given attention in relation to the conservation and fulfillment of human needs. Efforts to increase the population of the bird are made through the modification of breeding and captive breeding efforts so as to encourage the acceleration of the bird population in nature and on the other hand the community interest in the fulfillment of protein and economic needs can be accommodated. Therefore, basic knowledge of the wisdom of local communities are need to support the sustainability of this bird in nature. Studies of local community wisdom and natural nest site coverage data need to be immediately obtained to fullfil the purpose. This baseline data is a reference to the establishment of appropriate breeding sites and management is expected to increase the acceleration of this bird population in nature as well as economic improvement through an ecotourism village. This research was conducted in Minyambouw District around Arfak Mountains Nature Reserve for 2 years (2013-2014). The first year study aims to find out the location of active nesting sites and strategic location to serve as a breeding model. Some active bird nests of the bird have been found in the forest of Syoubri village and then mapped based on GPS data. In the second year, the collection of cultural data of the community (local wisdom) as the basis of customary rules that bind the community. Some people (50%) still do hunting for family consumption and income. To overcome this, the community agreed and happy to make the bird and its nest as a tourist attraction. In relation to that there is a need to do management of ecological tourism for the community and creation of a captive breeding programme through a hatchery effort on wattled brushturkey birds.

Abstract

A study has been conducted in the lowland of tropical rain forest, swamps and mangroves in the vicinity of Tapormay and Aindua villages in the Far-West Mimika District from Mimika Regency, Papua Province to examine the diversity of plant and animal species and the number of plant and animal species utilized by the Kamoro tribe in the villages in they everyday life. A descriptive method with survey technique and interview to the people in Tapormay and Aindua villages were used to carry out the study. The results of the study found 36 dominant plants species in lowland tropical rain forest, five dominant species in swamp forest and nine dominant plant species in mangrove forest. While as many of 35 wildlife species were encountered in lowland tropical rain forest, marshes and mangroves consisting of nine species of mammals/marsupials, 24 species of birds and two species of reptiles. Non-timber forest products recorded by the Kamoro in both villages were 47 species divided into 10 groups: food and beverages, household necessities, sleeping equipment and rain hood, hunting tools, medicines, oil, sources of firewood, tribe ornaments, wooden boats, and musical instruments. Based on the level of forest importance or the most important function of forest area for the Kamoro is as a place to find food, that is: sago and hunting. Interview with all respondents (100%) stated that the main function of the forest is where to take sago followed by hunting activities, picking up firewood, wooden boats, fruits and medicines, and taking building materials and bark.

Abstract

Mites have hostplant specifications or host plants. Mites can be destructive and deadly of which is the host plants a mango crop. Mites on mango crops will cause the leaves yellow and fall off prematurely. This is will lead to the disruption of the productivity of mango. It is necessary for research to identify the mites that infect the mango crop. The method is carried out by direct observation. Mites were taken from the surface of mango leaves later in preservation with several levels of concentration of alcohol, and polyvinyl laktofenol. Then, observed under a microscope and documented for identification purposes. Mites on the leaf surface of manalagi mango (Mangifera indica) found two species, it is Oligonychus sp. and Oligonychus ilicis (Family: Tetranychidae, Superfamily: Tetranychoidea). Oligonychus sp. hallmark is rounded body shape like a spider, with a body is transparent and there are two long seta on posterior part. While Oligonychus ilicis has a characteristic elongated rounded body shape, red, and there is a short posterior seta. Oligonychus sp. and Oligonychus ilicis live as parasites on the surface of mango leaves that can lead to wrinkled leaves, yellow and to fall. Oligonychus life cycle starts from the eggs develop into Nympha and then adult.

Abstract

Inter-annual climate variability (ENSO) become major issues for sciences for nowadays because the effect of globally. The purpose of this research is to know the characteristic of the climate on West Papua Region that can investigate and to know variable of the responds to every area of the ENSO phenomena. This is use for the climate parameter for rainfall and sea surface temperature (SST). Technic analysis begins to see periodicities rainfall using wavelet transformation. Next, analysis percentage of rainfall on the phases of ENSO Cases to see how big the influence of ENSO to the Increasing and Decreasing of rainfall in every region. Next step is to use statistic technical to see the connection between rain drop variable into the Standardized Precipitation Index (SPI) to the ENSO index. The result of wavelet analysis to the rainfall showed the domination of periodicities in one year, this indicated that the research area is effected by monsoon and local factors. The result of rain fall percentage and linier correlation analysis of ENSO index to the SPI in each territorial in general showed the ENSO influence. This can be shown by negative correlation score that means, when there is an EL NINO (La Nina) in Pacific Ocean at the same time there is a decreasing or increasing of rainfall in research territorial. The variation in each location responds showed the ENSO effect doesn’t have to influence directly to the rain fall in the research zone.

Abstract

Per capita expenditure is very important for a region, It’s estimation are only conducted at national to district level based on National Socio-Economic Survey (Susenas) data conducted by BPS. The survey was designed for a national scale, so the estimation would have low precision if used for smaller sub-populations, such as villages. One attempt to improve the precision of the estimation is by increasing the effectiveness of the sample size known as the small area estimate (SAE). One method in SAE that is very well used for continuous data is the Empirical Best Linear Unbiased Prediction (EBLUP). EBLUP method is used to estimate per capita expenditure of each village in Jember District by using companion variables, the percentage of the Askeskin recipients in the last year. The result is that the estimation of village per capita expenditure in Jember Regency by EBLUP method have better precision than direct estimation. There are three outlier data including Karangrejo, Jember Lor and Sumbersari that have very high per capita expenditures because they are located in urban areas
