Abstract

The developments research in the cluster analysis using the fuzzy method. The fuzzy method allocates to each group with membership value located at interval [0, 1], showing the magnitude of the possibility of an object being a member into a particular group. Outlier in data very important known before grouping, because affect the final result. Grouping by using the mean value as the center of the group will be more sensitive than using the median value, so this research applies fuzzy c-means and fuzzy c-medoid method to the grouping of villages in Sorong Regency Year 2016 based on the underdevelopment status and examine the goodness of both methods. There are 23.2% of villages that do not change when done grouping with both methods. Overall average distance of group center object and varians in the resulting group the two methods are the same, the varins between groups of fuzzy c-means is greater than the fuzzy c-medoid method.

Abstract

Geoelectrical Resistivity method is a geophysical method that can be used to determine subsurface geology based on rock resistivity image. Resistivity survey has been done in some villages, in Fak Fak Regency, West Papua Province. The measurement method that used is sounding, whereas electrode configuration used is Dipole-dipole configuration with a stretch of 100 -150 m. The data obtained are then processed by Progress Res2Dinv. The results of this survey obtained show that in the resistivity sounding measurement point found any good groundwater aquifers, as the water source of drilled well. Water layer with the thickness between 1-3 m at the surface (alluvial) is a rain water infiltration that is not recommended to make boreholes at this point.

Abstract

The purpose of this study is to identify types of dominant vegetations in the plantation area and former farmland as indicator of soil fertility. Vegetation plays an important role to provide soil fertilities. Certain types, growing in the former farmland can possibly indicate soil fertilities both in the plantation area and former farmland. Aspect of the fertilities likely influences number of vegetative types and diversity of species. Measured vegetation is used to comparing species composition and its diversities. The former plantation that is taken up as sample has been used for 5 year. Identification of the type was carried out by using vegetative analysis. The valuable index was calculated to determine extensively the role of the dominant types from seeding and wooded phase. There are four different plot sizes. 20x20 meter is utilized purposively for wooded phase, 10x10 meter is pole, 5x5 is used as stake phase and 2x2 meter is made for seeding phase. The species which has important role for the soil fertilities are indentified through exploring various references and the result of interview from local society The finding reveals that vegetative composition in the former farmland which has been used for 5 year consists of three phases, including seeding, stake and pole. Totally, the types are 30 species under each phase. 23 types are in the seeding, 19 types contribute for pole and 6 types are resulted in the wooded phase. The dominant type of seedling phase is Lunasia amara, Piper aduncum is gotten in the stake phase, and the pole one is Mallotus philippensis. However, differently the plantation area carried out 39 species in the seeding phase, sapling phases has 36 species, pole phase carries out 16 species and 17 species is in the wooden phase. The dominant types is in the seeding and stake phase is Nephelium lappaceum, Lansium domesticum is pole phase, and Durio zibenthinus is resulted in the wooded phase

Abstract

Malaria contagious by mosquito Anopheles Betina bringing protozoa parasite in its body (Plasmodium). Plasmodium there are four specieses that is Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and Plasmodium falciparum, but often becomes pathogen that is Plasmodium vivax and Plasmodium falciparum. As for intention of this research is to identify Plasmodium which is dominant at female Anopheles mosquito (Anopheles spp.) and knows distribution pattern of female Anopheles mosquito (Anopheles spp.) in some places in Districts Manokwari Barat. Based on research result done to four locations that is area Amban, Wosi, Sanggeng and Kota is found [by] 1024 mosquito tails. From the amounts only 115 mosquito tails was mosquito Anopheles Betina while the other is mosquito Anopheles male, mosquito Culex and Aedes. Mosquito Anopheles Betina found consisted of 4 species that is Anopheles bancrofti, Anopheles kochi, Anopheles farauti and Anopheles koliensis. Mosquito Anopheles Betina which is dissected, obtained 2 the Plasmodium species in mosquito spit gland is Plasmodium vivax and Plasmodium falciparum, and from calculation by index dominant can be told that both types of this very dominant Plasmodium in Districts Manokwari Barat because its the dominant index > 5%.

Abstract

One of the potential of the seven districts underdeveloped areas in West Papua Province is agriculture. In order to develop agricultural potential, an overview of agricultural products is needed including the similarity of regional characteristics and the relative position of the region. The similarity of regional characteristics to agricultural product can be known by cluster analysis. The relative posistion of the area with agricultural results is known by biplot analysis. Bintuni Bay Regency, South Sorong Regency, Tambrauw Regency and Maybrat Regency have the same characteristics in producing agriculture while Teluk Wondama Regency, Sorong Regency and Raja Ampat Regency have different characteristics. The relative position of agricultural products with the regency is Sorong Regency producing the highest number of food crops while the largest producer of horticulture fruits and vegetables are Teluk Wondama Regency and Raja Ampat Regency.

Abstract

Acid mine drainage is formed when certain sulfide minerals in rocks are exposed to oxidizing. Upon exposure to oxidizing conditions, these sulfide minerals are oxidized in the presence of water and oxygen to form highly acidic, sulfate-rich drainage. Acidity levels, and metal composition and concentration depend on the type and amount of sulfide mineral and the presence or absence of alkaline materials. If acid mine drainage has formed, it will be very difficult to stop the process as it is a continuous process until one of the reactions runs out. Acidic water containing heavy metals when flowing into rivers, loker or swamps will damage the condition of the ecosystem in the river. This will certainly cause a decrease in water quality. The purpose of this study is to examine the potential for the formation of acid mine drainage based on the acid base balance method. The results obtained in samples A, B1, B2, and C for the pasta pH test were 5.25, 4.20, 4.71, and 3.14, respectively. The results of the other parameters for the four samples were total sulfur contents (0.005%, 0.021%, 0.008%, 0.47%), acid neutralization ability (3.1, 2.82, 2.45, 13.07 kg H2SO4/ton), maximum acidic potential (0.153, 0.643, 0.245, 14.394 kg H2SO4/ton) and acid-base balance expressed as potential acid production (-12.917, -2.177, -3.065, 11,944). Evaluation of sample C data based on acid-base balance values (11.944 kg H2SO4/ton) and KPA/PKM ratio (<2, 0.17) indicating that sample C has the potential to form acid mine drainage if the coal mining process is carried out.
