PEMBINAAN DAN PENDAMPINGAN KEPADA PENAMBANG EMAS TANPA IJIN DI DESA NOELTOKO, KEC.MIOMAFFO BARAT, KAB.TTU

Exploitation of natural resources through unlicensed gold mining (PETI) is not in accordance with mining operational standards occurring along the Noeltoko River, West Miomaffo Subdistrict, Timor Tengah Utara Regency, East Nusa Tenggara Province resulting in damage and environmental degradation. Changes and environmental damage include the formation of dug holes around the river flow, turbidity of water, changes in river flow. Other problems that arise are conflicts between these PETI workers and with other communities. This community service activity aims to provide an understanding to the community about the importance of maintaining and caring for rivers from excavation in the river walls that can cause debris / landslides explaining the impact of the use of hazardous materials such as mercury / mercury and cyanide, socialization of regulations regarding the formation of People's Mining Areas (WPR) ), introducing "sluice box" equipment to help the process of separating gold sand from sand. This activity was supported by the UPT ESDM Atambua Branch and was followed by 40 people who used to mine on the Noeltoko river. It is expected that the guidance and assistance can raise public awareness to be able to mine but still preserve the environment Keyword: PETI, Noeltoko, WPR, sluicebox, Abstrak Eksploitasi sumber daya alam melalui Penambangan Emas Tanpa Izin (PETI) tidak sesuai dengan standar operasional penambangan terjadi di sepanjang sungai Noeltoko-Kecamatan Miomaffo Barat, Kabupaten Timor Tengah Utara Propinsi Nusa Tenggara Timur yang mengakibatkan kerusakan dan penurunan kualitas lingkungan. Perubahan dan kerusakan lingkungan tersebut diantaranya terbentuk lubang-lubang galian di sekitar aliran sungai, kekeruhan air, berubahnya aliran sungai.. Permasalahan lain yang timbul adalah konflik antar pekerja PETI ini maupun dengan masyarakat lain. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pemahaman kepada masyarakat mengenai pentingnya menjaga dan merawat sungai dari penggalian di dinding sungai yang dapat mengakibatkan runtuhan/longsoran menjelaskan dampak penggunaan bahan berbahaya seperti air raksa/merkuri dan sianida, sosialisasi peraturan tentang pembentukan Wilayah Pertambangan Rakyat (WPR), mengenalkan peralatan “sluice box” untuk membantu proses pemisahan buiran emas dari pasir.Kegiatan ini didukung oleh pihak UPT ESDM Cabang Atambua dan dikuti oleh 40 orang masyarakat yang biasa menambang di sungai Noeltoko. Diharapkan dengan adanya pembinaan dan pendampingan dapat menimbulkan kesadaran masyarakat untuk dapat menambang namun tetap menjaga kelestarian lingkungan Kata kunci: PETI, Noeltoko, WPR, sluicebox

1. Gold, sand, and string

‘Gold, sand, and string’ considers elements of the Periodic Table from which every material we use is built. It focuses on three materials—gold, sand, and string—that represent the metallic, inorganic, and organic resources on which we draw. The atomic structure of gold, silver, iron, and copper are described along with the important alloys that can be created from them: bronze, brass, and steel. Quartz (silica) and calcite are also important minerals used in glassmaking and cement manufacture, respectively. Cellulose, a polymer made up of a sugar-molecule chain, is the most abundant material in the biosphere. It is at the heart of cotton and the commodity materials of wood and paper.

Materials: A Very Short Introduction

The study of materials and their properties forms a major area of research that supports innovation and technology. Using modern scientific techniques, material scientists can explore and manipulate materials, and create new materials with remarkable properties. For example, material scientists now have the possibility of creating new materials that: combine hardness with flexibility; have the ability to store digital data; that can respond to their environment; and that can be scaffolds for the growth of new biological tissue. Materials: A Very Short Introduction begins with gold, sand, and string—representing the families of metals, ceramics, and polymers—and considers the properties and processes involved in their fabrication into objects, to show how materials science brings together engineering and technology with physics, chemistry, and biology.
