Abstract

Research on the analysis of groundwater quality in South Ternate District, Ternate City, North Maluku Province needs to be carried out considering that the community's water sources in the area come from groundwater (dug and drilled wells), so knowledge of groundwater quality in the form of pH, TDS, EC, and temperature be important. The purpose of this study is to determine the quality of groundwater; as well as recommendations related to groundwater quality in the South Ternate District area. The stages of the research method were carried out by collecting primary data in the form of well coordinates and elevation, physical properties of groundwater, groundwater quality measurement results and secondary data collection. The water quality results in the South Ternate District for the 40 samples measured ranged from pH 5.2 to 6.6; TDS 4-2150 ppm; EC 8-4240 µS/cm and temperature ranges from 26.5-29.7oC. Based on Permenkes Number 32 of 2017 concerning environmental health quality standards and water health requirements for sanitary hygiene purposes, only 3 wells had a pH in the range of 6.5-8.5, namely samples F-02, TO-01, and TO-02. The physical quality of groundwater shows that the closer to the east the pH is, the closer to neutral, while the west is lower. There are many low water pH because sampling is done in the dry season.Keywords: groundwater, water quality, pH, TDS, South Ternate

Abstract

Secara geologi, Pulau Morotai khusushnya Desa Daeo didominasi oleh batu gamping. Batu gamping banyak dijumpai tersingkap di beberapa titik pada Desa Daeo dengan ketebalan singkapan bervariasi. Batu gamping sebagai batuan karbonatan dapat dapat dimanfaatkan di berbagai sektor, seperti bahan baku semen, bahan konstruksi, pupuk pertanian, penjernih air, kosmetik, bahan pengolahan biji logam dan lain-lain. Metode pengumpulan data pada penelitian dengan melakukan observasi lapangan berupa pengambilan titik koordinat, pengambilan sampel batu gamping, preparasi sampel dan pengujian sampel dengan X-Ray Fluorescence (XRF). Data penelitian kemudian diolah dan dianalisis untuk mengetahui potensi pemanfaatan batu gamping di lokasi penelitian. Berdasarkan hasil penelitian, diperoleh 3 sampel batuan dengan komposisi kimia batuan masing-masing sampel MRT 1             0.52% Fe2O3, 4.56% MgO, 40.32% CaO, 0.28% SiO2, 0.01% MnO, MRT 2 0.36% Fe2O3 ,4.42% MgO, 43.53% CaO, 0.17% SiO2, 0.01% MnO dan MRT 3 0.50% Fe2O3 , 4.88% MgO, 40.08% CaO, 0.25% SiO2,0.01% MnO. Potensi pemanfaatan batugamping di Desa Daeo, Morotai untuk bahan bangunan, bahan penstabil jalan, dan bahan baku pupuk di sektor pertanian.

Abstract

In mining activities, there is often a discrepancy between the plan and actual conditions in the field. The purpose of this study is to determine the factors causing changes in Ni levels between exploration and mining activities. This study used drill sample data and mining samples using grab sampling (assay). From the results of the study, the Ni content value in exploration activities was 1.83% and in mining activities was 1.73% with a difference in content of 0.10%. The results of the difference in content are the influence of factors such as the heterogeneous nature of nickel, drilling activities, topographic conditions, mining methods, controlling factors for dilution, waste position to ore, reserve calculation methods, rainwater and human error.
