Abstract

Merkuri digunakan sebagai media untuk memisahkan emas dari batuan yang ditambang. Penelitian ini bertujuan untuk mengukur konsentrasi merkuri dalam tanah di daerah pertambangan emas di Desa Kalirejo. Lima belas sampel tanah dikumpulkan dari lokasi yang terkontaminasi. Sedangkan enam sampel tanah diambil di lokasi yang tidak tercemar, dan digunakan sebagai kontrol. Sampel tanah diambil pada kedalaman 30, 60, dan 90 cm. Hasil penelitian ini menunjukkan bahwa konsentrasi merkuri dalam sampel tanah berada di kisaran 0,30- 22,51 mg/kg. Nilai ini melebihi standar kualitas merkuri dalam tanah yaitu 0,3mg/kg.

Abstract

This community service activity was carried out in Oemofa Village with the aim of optimizing the potential of local resources and infrastructure through community empowerment. The method employed was a participatory approach, which included field observation surveys, focus group discussions (FGDs), training programs, and monitoring and evaluation. The results of the community service were implemented according to the initially planned stages. The activities were conducted together with the people of Oemofa Village, faculty members, and students from the Albert Foenay Institute of Technology. The activities included the installation of trash bins at the Oemofa market, tree planting in the courtyard of the sub-district office, a community service event in Dusun Satu involving all residents, the creation of a signboard for the Posyandu (integrated health post) named Tunas Mekar, and the development of an information board which is highly needed at the sub-district office, along with several other supporting programs. These activities contributed to strengthening the independence and welfare of the village community.
