Abstract

Geomorphology is the study of land shape, a process that causes the alteration of land shape and on both sides relationship between land shape and process of shape formation. In its application, Geomorphology is required in many fields which need land shape information and its implementation. Geomorphologic exploration results land classification into geomorphologic units. Erosion survey, by using geomorphologic approach, results some important information in land shape alteration such as to determine the cartography of design erosion, the cartography of erosion development, plain distribution into some 0erosion units that is marked by erosion intensity and the estimation of sediment result that is come from erosion process.

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan tumbuhan dalam mengakumulasi merkuri dari limbah akibat kegiatan penambangan emas tradisional di Sungai Tulabolo Kecamatan Suwawa Kabupaten Bone Bolango. Mengkaji serapan merkuri dengan sistem fitoremediasi di ekosistem perairan sebagai strategi pengelolaan ekosistem aliran Sungai Tulabolo akibat penambangan emas tradisional untuk mengantisipasi terjadinya pencemaran lingkungan. Mengkaji kondisi ekosistem perairan ( tumbuhan, air dan sedimen) sebelum dan setelah dilakukannya adanya fitoremediasi. Penelitian ini berlokasi di penambangan emas tradisional yang berada di Kecamatan Suwawa Timur Kabupaten Bone Bolango yaitu pada Daerah Mohutango di bagian tengah Sub DAS Tulabolo. Pengambilan sampel air dan sedimen dilakukan di Sungai Mohutango dan lokasi pengolahan sekitar daerah Fitoremediasi. Analisis merkuri di air dan sedimen dilakukan di laboratorium Perikanan Provinsi Gorontalo. Analisis merkuri pada tumbuhan dilakukan di laboratorium Penelitian dan Pengujian Terpadu Universitas Gadjah Mada. Hasil penelitian menunjukkan bahwa tumbuhan yang terdeteksi mengakumulasi merkuri terbesar di ekosistem Sungai Tulabolo berturut-turut adalah tumbuhan paku pakis, keladi tikus, colocasia esculenta red stem, rumput-rumputan (paspalum conyugatum) dan colocasia esculenta batang hijau. Tumbuhan colocasia esculenta (batang hijau) sangat toleran pada air limbah dan dapat menyerap merkuri dengan baik sehingga cocok digunakan sebagai media fitoremediasi di ekosistem Sungai Tulabolo. Hasil analisis menunjukkan bahwa kondisi lingkungan setelah fitoremediasi menjadi lebih baik terutama pada sedimen dimana merkuri mengalami penurunan yang sangat baik. Hasil analisis uji beda T-Test dengan paired samples test menunjukkan terdapat perbedaan yang signifikant antara penyerapan merkuri oleh akar tumbuhan sebelum dan sesudah fitoremediasi.

Abstract

This study aims to identify mercury concentrations in head hair and its effect on public health at the traditional gold mining. The study was conducted at the gold mining, Buladu Village, North Gorontalo Regency. Samples were taken randomly from human head hair. Samples of public health condition were taken from respondents who served as the samples of mercury concentrations in the head hair. The number of respondents was 20 people. The samples of mercury in the head hair were analyzed at the Integrated Research and Testing Laboratory of UGM by using mercury analyzer. The quality standard used as a reference to the mercury concentrations   in the head hair was the recommendation of the National Research Council (NCR), i.e. 12 ppm. The results of the analysis of the public health were tabulated and then interpreted. The results of the analysis indicated that the highest mercury concentration in the head hair was 952.85 mg/kg and the lowest was 0.03 mg/kg with an average mercury concentration of 55.09 mg/kg. This result was above the threshold quality standards established by NCR, i.e. 12 ppm. Many factors affect the mercury concentrations in humans, including education, income, environmental sanitation and food consumption. Waste dumped directly into the river will affect river water and marine aquatic animals. The consumption of food taken from the waters of Sulawesi Sea affects influence the mercury concentrations in the head hair.

Abstract

Gorontalo City is one of the regions in Gorontalo Province. Urban development and population growth, causing pressure on land use patterns. Changes in land use are carried out to meet the community's needs for infrastructure. At present, development in Gorontalo City is still ongoing. The increase in temperature is expected to continue and can trigger heat island. This is very important to be studied for the Gorontalo City development planning that is more environmentally friendly. This study aims to analyze the heat island phenomenon through the relationship of the spatial distribution of surface temperature with various types of land cover and vegetation characteristics. The object of this research is the Gorontalo City area on Landsat path-row 121- 65 satellite imagery media. The research material is the wavelength of visible light, near-infrared and moderate infrared and thermal wavelengths on satellite imagery of Landsat TM and OLI TIRS. The results showed an increase in temperature in Gorontalo City since 1990, 2003, and 2017. The correlation between surface temperature and land cover is negative. The value of the correlation coefficient (r) in 1990 was -0.41. The correlation coefficient (r) in 2003 was -0.448. The correlation coefficient (r) in 2017 is -0.402. Changes in surface temperature in Gorontalo City are influenced by changes in the land cover which is marked by the similarity of patterns of changes in surface temperature distribution with patterns of land cover changes.
