Study is learning scientific study. A Pareto chart is a diagram consisting of a bar graph and a line graph that illustrates a comparison of each type of problem data with its overall causes. Gross Regional Domestic Product (PDRB) is the total gross added value arising from all economic sectors in a particular area. Which is usually a Pareto Diagram made to describe the PDRB of a particular area which aims to help make regional policies or planning, evaluate development results, provide information that can describe the regional economic performance. In terms of the topic of this pareto diagram study, the author takes the exposure of rock mining in Manokwari Regency. The mining of these rocks is a source of income in the Manokwari Regency area which can support the economy in the Manokwari Regency area. Where mining activity or mining activity is a process or activity of taking material that can be extracted from the earth to the utilization of minerals, both for the benefit of the company, the surrounding community, as well as local and central government.
Natural resources, namely water, are abundant in Indonesia, which calls for all living things as a source of life. Therefore, abundant water resources must be protected and sustainably maintained, the use of water that is used properly and wisely by always taking into account the needs of children and grandchildren. The available water must be maintained in quantity and quality. Problems that often occur related to the availability of water, among others, the quantity of good water to use is limited while the need for water continues to increase, both for household, agricultural, and company needs. 2003). The decline in water quality is not only from industrial waste but also from household waste in the form of solid and liquid (Lallanilla, 2013). The purpose of this paper is to analyze the quality of river water and determine the status of the water quality of the Ayai River, Meyah District, Tambrauw Regency. The water quality of the Ayai River is based on the test results of several parameters. There is pollution downstream caused by the very high runoff, so it is contaminated with organic matter. The results of testing the water quality standards found that several parameters downstream of the Ayai River were lightly polluted. It was concluded that based on the calculation results of the Ayai river downstream of the river, there was pollution for parameters BOD5 6.4 mg/L, total phosphate 0.60 mg/L, zinc (Zn) < 0.065mg/L and Free Chlorine (CI2) < 0.12mg/ L which indicates that the water is in a polluted condition with these parameters.
Indonesia is a country that has natural resources (SDA). Mining materials are non-renewable natural resources. Mining materials include stone sand, silver, gold, copper, natural gas, and oil. Manokwari Regency is an area that has abundant natural resources. The company's mining activities have provided a reasonably comprehensive source of income for the regions in the last few decades. Mining has also triggered environmental problems that are closely related to land degradation. To overcome environmental problems from mining activities, it is necessary to the reclamation of ex-mining land. This paper aims to obtain a reclamation program, determine the form of revegetation, and obtain a direct and indirect cost budget at PT TAM. The mining area is carried out with an area of 9.1 Ha consisting of an area around the mine along ± 1.86 Km and supporting facilities with an area of 2.05 Ha such as workshops, offices, housing, and a stone crusher. Moreover, the rest is the mining area. The Reclamation activity program is carried out at mine sites, mining roads, and supporting facilities, with the reclamation technique carried out starting from the arrangement of the land surface, making drainage, sedimented pond, and revegetation. Revegetation is carried out in 3 stages. Among others, the first stage is planting cover crops. The second stage is planting the main crop and maintenance. The amount of reclamation guarantee must be paid by PT. Tri Abadi Mineral (TAM) is Rp. 101.260.125,-.
