Abstract

The increasing mining activities have led to the problem of acid mine drainage (AMD) pollution. A method that combines biochar treatment as an adsorbent with wetland sediment treatment as a source of sulfate-reducing bacteria is used to address AMD effectively. This research aimed to determine the ability of biochar in combination with wetland sediment treatment to reduce sulfate and heavy metal content in acid mine drainage wastewater. This research was conducted on a laboratory scale in an AMD wastewater treatment reactor with the following treatments of biochar mixed with wetland sediment. Observations included sulfate content, pH, and heavy metal content. Scanning electron microscope (SEM) analysis was also performed on the biochar. SEM observations revealed the presence of small, dense, and irregularly shaped pores on the surface of the biochar. The results on day 30 showed that biochar mixed with wetland sediment was able to reduce sulfate concentration by 74.19% and reduced Pb by 73.79%, compared with treatment sediment only to 64.81% sulfate concentration and reduced Pb by 53.85%, treatment biochar only had reduced sulfate of 46.90% and reduced Pb by 58.67% and control 1.79% sulfate concentration and reduced Pb by 1.87%.

Abstract

Kabupaten Kolaka memiliki jumlah nelayan sebanyak 3566 jiwa dengan rincian sebanyak 643 orang untuk 224 kepala keluarga yang berasal dari suku bajo yang bekerja sebagai nelayan penuh waktu di Kecamatan Tanggetada. Kelurahan Anaiwoi terletak di pusat pemerintahan ibu kota kecamatan Tanggetada. Setiap kali musim hujan tiba dengan intensitas tinggi maka akan terjadi fenomena naiknya muka air laut yang menyebabkan aktivitas sehari hari warga tergangu termasuk aktivitas melaut. Masyarakat suku bajo Kelurahan Anaiwoi menjadikan laut sebagai sumber mata pencaharian utama sehingga perubahan iklim akan sangat mempengaruhi tingkat kesejahteraan masyarakat. Permasalahan lain yang ada pada masyarakat suku bajo adalah kesadaran akan kelestarian dan keberlanjutan lingkungan yang masih sangat rendah. Laut masih merupakan tempat pembuangan sampah/limbah rumah tangga bagi sebagian besar masyarakat pesisir.

Abstract

Food gardening is an alternative to meet the food and nutritional needs of the family. Empowerment the community in the nickel mining area of Pesouha Village, Kolaka Regency is carried out using the DFT hydroponic system with the aim of ensuring adequate family food through PKK groups in degraded environments. Community empowerment is carried out in 4 stages, namely (1) socialization stage (2) training stage (3) product packaging stage and (4) monitoring and evaluation stage. The results obtained from this community empowerment activity are that the PKK group partners of Pesouha Village have understood, have the ability and infrastructure for hydroponic planting in their yards

Abstract

This research is a study of FM and FR calculations on post-mining land as well as the identification of Vesicular Arbuscular Mycorrhiza (VAM). on post-nickel mining land. In this research, the method used was a descriptive method. The results obtained were analyzed using descriptive statistics, namely presenting the Vesicular Arbuscular Mycorrhiza (VAM) genera. Calculations were also carried out using statistical formulas which included absolute frequency which shows the presence of a species in a sample and relative frequency which shows the presence of a species in a population (number of spores per 100g of soil). Based on the results of this research and discussion, conclusions can be drawn: 1) The results of identification of the diversity of VAM spore types in post-nickel mining soil found 3 mycorrhizal genera, namely Glomus sp, Acaulospora sp and Gigaspora sp. 2) The results of calculating the largest Absolute Frequency (FM) value are 87.5% and the lowest Absolute Frequency value is 12.5%, while the results of calculating the largest Relative Frequency (FR) value are 8.72% and the lowest relative frequency value is 0.67%.
