Abstract

Coal mining is a significant contributor to the economy of East Kalimantan Province, with most activities employing open-pit mining systems involving stripping and transporting soil surface. If not properly managed, these activities can lead to Acid Mine Drainage (AMD), which is rainwater and groundwater reacting with sulfide content. Without any treatment before discharge into the environment, AMD can cause environmental pollution. One such treatment method is constructed wetlands, utilizing Pontederia crassipes to absorb heavy metals present in AMD. This study aims to determine the phytoremediation effect on the pH and TSS of acid mine drainage using constructed wetland methods. The research was conducted at PT. Lanna Harita Indonesia, using three 60x50x50 cm container boxes as a collection pond for AMD, a phytoremediation pond containing sand, zeolite rock, and filter cotton, and a constructed wetland phytoremediation pond containing Pontederia crassipes. The results show that Pontederia crassipes can increase the acidic pH from 4.11 to 7.65 and reduce the TSS value from 1016 mg/L to 22 mg/L. This indicates that the final AMD values after phytoremediation treatment comply with the quality standards outlined in East Kalimantan Regional Regulation No. 2 of 2011, meaning it is suitable for discharge into the environment with minimal negative environmental impact.

Abstract

Environmental conditions and community activities impact surface water and groundwater quality. Physical, chemical, and biological parameters can be used to assess water quality so that i can be used by established quality standars. This study aimed to assess the quality of surface water and groundwater around the Samarinda State Agricultural Polytechnic using TDS, pH, COD, Fe, and Zn parameter sat eight different sampling locations. Water quality assessment based on physical and chemical parameters follows the guidelines of Goverment Regulation No. 22 of 2021. Based on the research results, the TDS value range is 61 mg/L – 320 mg/L; the pH value range is 5,4 – 7,97; the COD value range is 136 mg/L – 208 mg/L; the Fe value range is between 21,4 mg/L and 27,3 mg/L, and the Zn value range is between 0,89 mg/L and 1,44 mg/L. This indicates that some water quality parameters, including COD, Fe, and Zn, do not meet the quality limits set by Government Regulation No. 22 of 2021.

Abstract

Clean water is used daily for drinking, sanitation, and other activities that support human life. Clean water has requirements in terms of quality and quantity. Clean water requirements include physical, chemical, and biological parameters with specific threshold values so that, it will not cause side effects when consumed. The quantity of clean water provided can be seen from the amount of raw water available to meet regional needs. This study aims to determine the potential for a clean water supply in the Bira Beach Tourism Area of Bulukumba. The alternatives include boreholes, Regional Drinking Water Company, rainwater harvesting, domestic wastewater reuse, and seawater desalination. The method used in this research is Break Event Point (BEP) to determine the economic price of each alternative water supply and the Analytical Hierarchy Process (AHP) method to choose the most suitable alternative to be used by calculating six criteria, namely quality, quantity, continuity, ecology, and technology. The results of this study indicate that the lowest BEP value is a borehole at IDR 302, then Regional Drinking Water Company at IDR 2,500, seawater desalination at IDR 4,022, domestic wastewater reuse at IDR 6,300 and rainwater harvesting at IDR 16,834, and the results of research using the AHP method rainwater harvesting and wastewater reuse get the highest value of 108.52 and 69.04 respectively.

Abstract

The strategic role of the agricultural sector in Samarinda City, particularly in North Samarinda District, supports food security and the regional economy. North Samarinda District holds a crucial position as an agricultural buffer zone in Samarinda, but in the past five years, there has been a significant decrease in horticultural production, such as tomatoes from 1,467.9 tons in 2021 to 263 tons in 2024, chilies from 236.2 tons to 129.9 tons, and shallots from 7.5 tons in 2022 to 1.1 tons in 2023. Various challenges, including climate change, land degradation, and urbanization, have contributed to a decline in agricultural productivity. This study aims to evaluate land suitability to optimize horticultural crop production in the region. The research method employed is a land suitability analysis using a Geographic Information System (GIS) approach, which identifies biophysical factors such as soil texture, pH, and soil depth, as well as soil sampling for further analysis. The results show that most of the land in North Samarinda District has S3 (marginally suitable) land suitability for shallots, chilies, and tomatoes. The suitability class for S3 is influenced by limiting factors such as rainfall, soil pH, erosion, and slope. Further discussion reveals that technical improvements, such as fertilization, the addition of organic matter, and terrace construction, can enhance land suitability. Through appropriate technical improvements, land suitability can be upgraded to class S2 (moderately suitable), which in practice will support increased horticultural yields and strengthen food security in North Samarinda.
