Abstract

This study aims to determine community’s perceptions of waste management, determine the value of Willingness to Pay (WTP) and analyze the household characteristics (X), which as the perception of waste management (X1), income (X2), family number (X3) and education level (X4). These factors are expected to affect the amount of the WTP value. The study was conducted in the District of Manokwari Barat approximately two months (May to June 2016). Total of 60 respondents distributed in 6 villages. Most of the respondents said (55%) that the dustman activities done quite well. However, the placement of the container is limited only in the activity center. The majority respondents (61.67%) only use plastic bags for garbage container. The cost of taking out the trash is Rp. 5000 s / d Rp. 20,000, and the weekly cost they spend Rp. 10.000 s / d Rp. 60,000. The majority respondents (80%) stated that the garbage collecting process has done fairly well, the dustman collecting garbage every day with limited fleet and funds. The majority of respondents (56.67%) said the process of garbage removal and transport has done fairly well, well (21.67%), and unfavorable (21.67%). The majority respondents (61.67%) said that the implementation of the landfill were done well, rubbish was dumped without any treatment. This research result that the WTP group of Rp. 50,000 / month was 60%, the Group of WTP Rp. 75,000 / month was 6.67%, and Group WTP Rp. 100,000 / month was 33.33%. Potential retribution Rp. 1.258.563.333 / month. Based on the multiple regression analysis that the entire household characteristics significantly affect the value of WTP, which the value of R2 was 0,513. The coefficient value of each variables to the WTP were X1 (-14,046.268), X2 (0.005), X3 (-6,882.381), and X4 (9,813.867). The F-test was resulted that Fcount at 14.478 higher than Ftable at 2.54, this mean that all variables simultaneously throughout the study variables significantly influence the public decision give WTP values (Y). Similar results were on the t-test results, partially any study variables significantly influence the decision of the community provides WTP values (Y). The tcount was X1 (-2.897), X2 (2.605), X3 (-2.260), and X4 (2.646) higher than ttable at 1.673.

Abstract

Mangrove forest is a vegetation that grows in the estuary beaches and who has the function of ecological, biological, economic and social culture, but now its existence has been degraded by the use of a less appropriate or changing function. Research on the structure of mangrove forest vegetation in the Wasti Bay Sowi IV Manokwari District of Southern District Manokwari conducted in April 2018 with the aim to determine the structure of mangrove forest vegetation and utilization. The method used in this research is the approach of ecological (biological) and anthropological approach. From the analysis of vegetation, found as many as 8 species of mangrove plants. Rhizophora apiculata is the dominant species on the level of a tree with a Density Value of 784.66 Individuals/Ha with an Important Value Index (IVI) 50.06 followed Rhizophora mucronata with a Density Value of 770.34 Individuals/Ha with the Important Value Index (IVI) 41.01. At the level of belta Rhizophora mucronata is the dominant species with a Density Value of 385.66 Individuals/Ha with the Important Value Index (IVI) 45.13 then Rhizophora apiculata with a Density Value of 263.33 Individuals/Ha with the Important Value Index (IVI) 40.22. At the seedling stage Rhizophora mucronata a dominant species with a Density Value of 760.00 Individuals/Ha with the Important Value Index (IVI) 45.42 and Rhizophora apiculata had Density Value of 681.66 Individuals/Ha with the Important Value Index (IVI) 41.04. Based on interviews of 8 mangrove species found in the observation plot, 3 species used as building material, 6 species as a source of firewood, 3 species as drugs and 5 species for other purposes.

Abstract

Law number 41 of 1999 concerning Forestry mandates to maintain the area of ​​forest area and forest cover for each rivers at least 30% of the total area, with a proportional distribution. The purpose of this study was to determine the area and percentage of the area and forest cover in the three watersheds, Arui, Prafi, and Wosi, in Manokwari District, analyze the composition, distribution, and changes in the area and forest cover, and describe the factors that influence these changes. this uses descriptive methods with quantitative analysis techniques. Data collection and analysis is done spatially using ArcGIS / ArcMap 10.1 software. The research variables consisted of area and forest cover in the watershed, composition, distribution, and change in the area and forest cover, area of ​​forest cover inside and outside the area expressed in hectares (ha) and percent (%), as well as factors that influence changes in the area and forest cover. The results showed that until 2016, the percentage of forest area to the total watershed for the two watersheds (Arui and Prafi) was still above 30%, while the Wosi watershed was only 14.79%, but the percentage of forest cover for the three watersheds was still above 30% The composition of the Arui and Prafi Watershed Forest Areas is dominated by Permanent Forests, whereas the Wosi Watershed is dominated by convertible Production Forests. In the Arui and Prafi watersheds, the distribution of the forest area is more concentrated in the upstream area and is dominated by primary forest, while the Wosi watershed is only in a portion of the upstream area with a predominance of secondary forest. During 2006 - 2016, the largest deforestation occurred in the Arui watershed (4.71% at a rate of 121.80 ha / year), conversely the highest forest degradation occurred in the Wosi watershed (39% at a rate of 5.31 ha / year). The dominant factor causing the change in the area in the three watersheds is thought to be a factor in partial change of forest area designation and Changes in Spatial Planning for the Provinces of West Papua and Manokwari in 2013-2033. Furthermore, population growth and land conversion to oil palm plantations, both by companies and communities, are the dominant factors causing deforestation.

Abstract

Sorong is one of the most advanced and most populous cities in the province of West Papua, with a population of 2016 reaching 232,833 people and a population growth rate of 3.21 percent per year (BPS, 2016). As the most populous city, of course, the problem of waste becomes a significant threat, especially related to the increasing volume of waste production both from households and businesses and also the tendency to dispose of waste improperly that results in environmental pollution. The purpose of this study was to determine the extent of environmental pollution due to plastic waste in the City of Sorong, then look further at the management of mineral water plastic bottles, and determine what factors influence the amount of plastic bottle waste in the City of Sorong. The analytical method used in this research is descriptive qualitative analysis. Based on the results of the study it can be seen that the waste management process is carried out by several parties, among others: carried out by the Government using an integrated management system, then by the community with an individual management system, and by the private sector through the Sorong Raya Garbage Bank. Factors that influence the amount of plastic bottle waste include: The level of community / business actors' knowledge about waste, their attitude about waste management, their behavior in managing waste, and the activities of government administrators such as studies on waste, socialization of facilities and regulations, and the adequacy of the APBD budget. and also external participation.
