Abstract

This research aim was toevaluate land suitability for dragon fruit plantation in  Maku village, Dolo sub district, Sigi Regency, Central Sulawesi Province. Seven land units were evaluated for their suitability. Survey was conducted in seven land units for observation on soil drainage, slope, stones, and root depth. Undisturbed and disturbed soil sample were taken from each land unit for physical and chemical analyses in the Soil Laboratory of Agriculture Faculty Tadulako University.  Of the seven land units, one land unit was classified as actual N1 (currently not suitable), another one land unit as S2 (moderately suitable) whereas the other five land units were categorized as actual S3(marginally suitable). The limiting factorsconsisted of texture, water, and soil pH. By correcting all the limiting factors existing in all land units, the actual classes of N1, S3 and S2 can be changed into the potential classes of S3, S2, and S1, respectively.

Abstract

The research was conducted in Lake Lindu Watershed Sub DAS Palu of Lindu Subdistrict of Sigi Regency and soil analysis was carried out in Soil Science Laboratory Laboratory of Tadulako University. The purpose of this study is to predict the rate of soil erosion and determine the index of erosion hazard in some land use in Lake Lindu watershed area Palu Sub-waters of Central Sulawesi Province. The benefits of this research are as a source of information for the government in general and provide information on the size of the erosion hazard index on some agricultural and non-agricultural land use so that it can be used sustainably. This research method was done by using survey method, soil sampling, soil anilisis, type and source of data and collect data through observation and interview. Data processing to obtain the result of erosion prediction is processed by using USLE equation (Universal Soil Loss Equation) by entering primary data and secondary data into USLE equation that is long and slope factor, Plant Management Factor and Soil Conservation Factor (CP), tolerated Erosion (TSL), and the Erosion Hazard Index (EHI). Based on the research conducted in Lake Palu Lake Basing Sub Palu about the prediction of erosion on some land use it was found that the erosion hazard that occurs in some units of land in Lake Lindu watershed Palu sub watershed included in the criteria of high, medium to low. The average value of erosion thatwas tolerated 17.07 ton-1year-1. The rate of erosion in Lake Lindu Watershed Palu is dominant due to soil erodibility, crop management and conservation measures. Conservation actions that need to be done are to maintain the existing vegetation, the use of plant remains as mulch, the use of bench terraces, guludan, reforestation and land evaluation.

Abstract

Penambangan emas di Desa Poboya merupakan salah satu wilayah pertambangan emas rakyat yang ada di Kabupaten Sigi-Biromaru. Kegiatan penambangan tersebut dilakukan oleh sekelompok masyarakat dan menggunakan cara-cara penambangan yang sangat sederhana (tradisional). Penambangan yang dilakukan mengakibatkan lingkungan menjadi rusak.  Logam berat merupakan istilah yang digunakan untuk unsur-unsur transisi yang mempunyai massa jenis atom lebih besar dari 6 gcm-3. Merkuri (Hg), timbal (Pb), tembaga (Cu), kadmium (Cd) dan stronsium (Sr) adalah contoh logam berat yang berupa kontaminan yang berasal dari luar tanah dan sangat diperhatikan karena berhubungan erat dengan kesehatan manusia, pertanian dan ekotoksikologinya. Lingkungan yang terkontaminasi oleh merkuri dapat membahayakan kehidupan manusia karena adanya rantai makanan.  kontaminasi merkuri pada tanaman  harus ditempatkan secara khusus dan ditangani secara hati-hati.  Penelitian ini dilaksakan dengan tujuan untuk mengetahui kandungan merkuri di kawasan pengolahan tambang emas Poboya.  Metode penelitian yang digunakan dalam penelitian ini adalah metode survey yang menggambarkan/menguraikan sifat dari suatu keadaan lokasi secara aktual dan mengkaji penyebab dari gejala-gejala tertentu. Dalam penelitian ini dilakukan pengukuran, pengamatan  dilapangan dan pengkuran laboratorium, pra survei, survei utama (pengambilan sampel) dan analisi laboratoruim, dengan pengambilan sampel secara taktis.  Hasil penelitian menunjukkan bahwa kandungan merkuri (Hg) pada sampel yang mewakili lokasi penelitian adalah tidak semua sampel tanaman menunjukan kandungan merkuri melewati ambang batas berdasarkan acuan Alloway, (1995) Konsentrasi merkuri (Hg) dalam tanaman kacang tanah berkisar 0.098 ppm- 0.45 ppm, pada tanaman jagung berkisar 0.07 ppm sampai 0.43 ppm, pada tanaman padi berkisar 0.03 ppm - 0.21 ppm dan pada tanaman bawang merah berkisar 0.01 ppm - 0.32 ppm. Kandungan logam berat merkuri (Hg) dalam tanaman di areal kelurahan Poboya masih dalam ambang yang bisa di toleransi namun menghawatirkan.

Abstract

Along with the discovery of several gold prospects area in ??Central Sulawesi, gold mining had increased both by companies, cooperatives and illegal mining. The activity of this mining produce waste that consist of hazardous toxic substances in which there was a heavy metal such as mercury (Hg). This metal is one of the trace elements that has liquid at room temperature, high specific gravity and power electric conductivity, and a toxic chemical element became a global concern because has significant hazardous effect on human health, wildlife and ecosystems. This study was  aims to know the content of mercury in soil around the Poboya?s gold mining. The method used in this study was a survey which describes the actually condition of this area and assess the causes of certain symptoms. In this study measurements, field observations, and laboratory analysis had been done. There step that be noticed in this survey were pre-survey, main survey (sampling) and laboratory analysis. Compose soil sample for laboratory analysis had been collected from several sample point that had been plotting by tactics. The results of this study showed that the content of mercury in all representative soil sample and tailings had highest than threshold. Normally, concentrations of mercury in the soil range from 0.03 ppm (normal) to 0.3 to 0.5 ppm (critics); while concentrations of mercury in soil agricultural areas ranged from 0.057 ppm to 8.19 ppm and in tailings ranged from 84.15 ppm - 575, 16 ppm.
