The performance of a pseudo‐natural wetland to purify wastewater for irrigation potential was explored in this study. To study the system's performance and the hazard level of the raw wastewater and treated effluent, several water quality parameters were chosen, including electrical conductivity (EC), total dissolved solids (TDS), sodium (Na+), calcium (Ca2+) and magnesium (Mg2+). Four different sampling points (inlet, two intermediate points, and the outlet) were investigated in the study. According to the electrical conductivity, wastewater flowing to the wetland was classified as category four (C4), ‘extremely high salinity’ and thus unfit for irrigation. Both intermediate sampling points were in C3, whereas the outlet sampling point was in C1. According to SAR, 20% of the samples collected at the inlet were classified as ‘very high sodium hazard’ (S4), 45% as ‘high sodium hazard’ (S3) and 35% as ‘medium sodium hazard’ (S2). The findings of this study also demonstrated that the pseudo‐natural wetland can be significantly effective in reducing pollution and providing suitable water for irrigation. Furthermore, the findings raise greater awareness of the importance of protecting and conserving these valuable resources, particularly in urban areas.

The irrigation suitability potential of an effluent treated by a pseudo‐natural wetland

The growth rate of mineral mine exploitation is increasing due to the advancement and sophistication of industrial technology equipment, causing the carrying capacity of the environment to be exceeded and becoming a threat to the sustainability of natural resources and causing environmental damage. This research studies the impact of environmental damage on andesite mining activities in Gampong Kuala Ligan, Sampoiniet District, Aceh Jaya Regency, making a good mining management strategy for good mining practice. Environmental damage impact analysis using data collection and maps, weighting and scoring as well as strength, weakness, opportunity, and threat analysis. Overlay analysis shows the mining location including the eligible and conditionally eligible mining areas. Impact forecasts at the research site include topography, landslide process, erosion rate, sources of livelihood and income levels of the population, as well as public health, are the significant impacts. In contrast, land cover vegetation and crime rates are insignificant impacts. The matrix analysis shows that the research site is in very unfavorable situation. So a strategy turn around in needed which utilizes strengths to overcome threats. In the External Strategic Factor Analysis, the total score for strengths minus weaknesses is 2.29 and the total score for opportunities minus threats is -0.33. Analysis of internal and external factors shows that environmental management strategies that need to be carried out are implementing bench system mining technology, making drainage channels, providing socialization and making regional regulations that technically regulate mineral mining management for impact control and control in limiting land clearing and carrying out reclamation post-mining area. For occupational accident, risk management theory is carried out through elimination, substitution, engineering design, administration, and personal protective equipment (PPE).

Suitability of shallow groundwater for irrigation: the case of the wonji shoa sugar estate (ethiopia)

Abstract: Utilization of groundwater sources is still an alternative for people living in the coastal areas of Aceh Besar District. If the use of groundwater is carried out continuously, it will have a negative impact on the quality and quantity of groundwater. So the purpose of this study was to determine the distribution of groundwater salinity in the coastal areas of Aceh Besar District. The sample points were determined based on the random sampling method in grids. Sample testing for groundwater salinity was carried out directly in the field according to the planned location. The data obtained was inputted into Microsoft excel and mapping of groundwater salinity distribution using the Inverse Distance Weight (IDW) method with Argis software. A correlation test was performed with Pearson Product Moment.  Based on the measurement results, 20 sample points of high salinity were measured. The distribution of salinity values also has a relationship with coastal distance, where the distribution of salinity in general, the farther the groundwater is from the coast, the lower the salinity value, and the closer the groundwater to the coast, the higher the salinity.Abstrak: Pemanfaatan sumber air tanah masih menjadi alternatif bagi masyarakat yang tinggal di wilayah pesisir Kabupaten Aceh Besar. Jika pemanfaatan air tanah dilakukan secara terus-menerus akan berdampak negatif secara kualitas dan kuantitas air tanah. Sehingga tujuan penelitian ini adalah untuk mengetahui sebaran salinitas  air tanah di wilayah pesisir Kabupaten Aceh Besar. Titik sampel ditentukan berdasarkan metode random sampling in grids. Pengujian sampel untuk salinitas air tanah dilakukan langsung di lapangan sesuai dengan lokasi yang telah direncanakan. Data yang diperoleh diinput ke dalam Microsoft excel dan pemetaan distribusi salinitas air tanah menggunakan metode Inverse Distance Weight (IDW) dengan perangkat lunak Argis. Uji korelasi dilakukan dengan Pearson Product Moment. Berdasarkan hasil pengukuran, nilai salinitas yang tinggi terukur sebanyak 20 titik sampel. Nilai salinitas tinggi pada umumnya dipengaruhi oleh intrusi air asin terhadap air tawar. Faktor sebaran salinitas air tanah terjadi akibat intrusi, penggunaan lahan yang dekat dengan tambak dan muara sungai, faktor sebaran salinitas juga dipengaruhi oleh kepadatan penduduk. Sebaran nilai salinitas juga memiliki hubungan dengan jarak pantai, dimana sebaran salinitas secara umum, semakin jauh air tanah dengan jarak pantai maka nilai salinitasnya semakin rendah, dan semakin dekat air tanah dengan jarak pantai maka salinitasnya semakin tinggi.

Spatial Distribution of Groundwater Salinity In The Coastal Area of Aceh Besar District

The aim of this study is to evaluate the groundwater quality in shallow aquifers from West Aceh, Sumatra, for irrigation uses. Groundwater samples have been collected from 32 stations for pH, electrical conductivity (EC), sodium adsorption ratio (SAR), total dissolved solids (TDS), sodium percentage (per cent Na) and residual sodium carbonate (RSC) analysis. Evaluation of water quality for irrigation using the United States Salinity Laboratory classifications suggests that the majority of the groundwater samples are good for irrigation. The crop tolerance of irrigation water salinity, as based on EC value, showed that paddy (rice), soybeans and sweet tomatoes are suitable for agricultural cultivation, but that corn and field beans are not suitable. Results indicate that, if used for agricultural irrigation, the groundwater quality ranges from excellent to good, except for a few locations (e.g. Meureubo sub-district) which indicate signs of deterioration.
