This study aimed to obtain a more comprehensive analysis of sulfate concentration of in Sungai Batang Arau, Padang. In addition to concentration profile of sulfate, correlation analysis between sulfate and environmental parameters (flowrate-Q, temperature-T, pH, DO and electrical Conductivity-EC) and spatial variation analysis of sulfate along the river were also performed. The analysis showed sulfate concentration tended to increase from upstream to downstream. Sulfate concentrations ranged from 25.9 to 115.1 mg / L and were below the quality standard (400 mg / L). Spearman Rank Correlation analysis showed a relative strong correlation of sulfate and significant with Q (r=0.581, p=0.000), T (r=0.448, p=0.008), and DHL (r=0.411, p=0.008) and no correlation with pH (r=-0.194, p=0.231) and DO (r=-0.279, p=0.081). Result of spatial analysis with a one-way ANOVA at 95% confidence level indicated that there was no a significant variability of sulfate concentration at the sampling stations (p> 0.05) except for S1 with S7 and S8. Moreover, cluster analysis grouped 8 sampling stations into two clusters, low and moderate polluted, based on similarities of sulfate characteristics. Keywords: Batang Arau, sulfate, correlation analysis, spatial variation analysisABSTRAKPenelitian ini bertujuan untuk memperoleh gambaran yang lebih lengkap tentang konsentrasi sulfat dan parameter lingkungan (debit, Q; pH, temperatur, T; dissolved oxygen, DO; dan daya hantar listrik, DHL) di Sungai Batang Arau, Padang. Selain menyajikan profil konsentrasi dan membandingkannya dengan baku mutu pada Peraturan Gubernur Sumatera Barat No. 5 Tahun 2008, analisis korelasi antar parameter dan variasi spasial konsentrasi sulfat di sepanjang sungai juga dilakukan. Hasil analisis menunjukkan konsentrasi sulfat cenderung meningkat dari hulu ke hilir sungai begitu juga dengan parameter lingkungan. Nilai konsentrasi sulfat secara rata-rata berada pada rentang 25,9-115,1 mg/L dan berada di bawah baku mutu (400 mg/L). Analisis korelasi Rank Spearman menunjukkan bahwa parameter sulfat berkorelasi cukup kuat dan signifikan dengan Q (r=0,581, p=0,000), T (r=0,448, p=0,008), dan DHL (r=0,411, p=0,008) dan tidak berkorelasi dengan pH (r=-0,194, p=0,231) dan DO (r=-0,279, p=0,081). Analisis spasial dengan one-way ANOVA pada tingkat kepercayaan 95% menunjukkan perbedaan lokasi sampling tidak mengakibatkan perbedaan konsentrasi sulfat yang signifikan (p>0,05), kecuali antara titik S1 dengan S7 dan S8. Lebih lanjut, analisis spasial dengan menggunakan analisis klaster mengelompokkan titik sampling ke dalam dua klaster, yaitu klaster 1 yang terdiri dari titik S1 sampai titik S7 dan klaster 2 (S8) yang menggambarkan perubahan konsentrasi pencemar sulfat dari konsentrasi rendah ke konsentrasi sedang.Kata kunci: Batang Arau, sulfat, analisis korelasi, analisis variasi spasial

Pumice is known as a low-cost material with a porous structure, has the potential as an adsorbent to remove various kinds of pollutant compounds. The abundance of pumice is found in Sungai Pasak area and it never been utilized. This study was performed to see the ability of Sungai Pasak pumice as an adsorbent for ammonium removal in water along with its ability to be regenerated. The study was carried out triplo in batches to obtain optimum adsorption conditions which were then used in desorption experiments using HCl 0.1 M agent for regeneration process. The optimum conditions obtained: adsorbate pH 6, adsorbent dose 0.3 g/l, contact time 30 minutes, adsorbent diameter <63 µm and adsorbate concentration 4 mg/l. The results showed that pumice has ability to remove ammonium with adsorption capacity at optimum conditions were 47.06% and 6.27 mg/g with Freundlich's isotherm equation (R2=0.997). Acid agents are able to adsorb ammonium from pumice with an average desorption percentage 88.89% after 2 times of reuse, proving that acidic agents are able to regenerate pumice adsorbents so they can be reused. The potential for adsorption and regeneration of the Sungai Pasak pumice can be utilized to treat water with ammonium such as groundwater and waste water.

Introduction: Padang City Sanitation Working Group reported that 34.32% of households in Padang City use unsafe latrines with septic tanks that still do not meet the standards which potentially causes the wastewater from the septic tanks to contaminate the water of the wells. This study was conducted to analyse the effects of the septic tank condition on the microbiological quality parameters of the well-water, namely total coliform and Escherichia coli in Koto Tengah District, Padang. Methods: This study uses a quantitative research method. The data were collected by questionnaires, observation, interviews, and laboratory tests. Water sampling was collected by using the purposive sampling method where the water is taken from 20 wells originating from 10 coastal and 10 non-coastal areas. Results and Discussion: Total coliform was found in all samples, while Escherichia coli was found in two samples from coastal and five from non-coastal regions. The septic tank condition had a strong correlation with the total coliform concentration (r= -0.531) and affected the total coliform concentration in the well-water by 30.8%. However, the Escherichia coli concentration was not related and not affected by the condition of the septic tank (p>0.05). There was no significant difference in the concentration of the microbiological parameters in the coastal and non-coastal areas. Conclusion: The microbiological quality of the well-water did not comply with the quality standards to be used as water sources for the community. The total coliform concentration in the well-water was shown to have a close relationship with the septic tank's condition.

Sanitation in Indonesia is defined as efforts to dispose of liquid waste and domestic waste to create a clean and healthy living environment both at the household and settlement levels Domestic waste management needs to be considered in managing a settlement Domestic waste products, especially those containing human feces, contain dangerous pathogens. If it is released directly into water bodies without processing it will result in environmental pollution Technology and knowledge are needed to accelerate the implementation of development states that technology options are highly dependent on technical and non-technical aspects; environmental factors, cultural and behavioral factors, as well as capital and recurring cost factors To analyze the choice of technology, determined based on perception using the Process Hierarchy Analysis (AHP) method. the AHP method can be used in determining sanitation technology in specific areas in order to obtain the most suitable sanitation technology for use in specific areas. The selected sanitation technology is a recommendation that is acceptable to the local population. Based on this, in order to accelerate the implementation of development, it is necessary to determine the right choice of sanitation technology for slum settlements in Bangko City, Merangin Regency. The selection of sanitation technology in the most effective waste treatment technology in Bangko uses the AHP method, namely conducting sewage treatment by suctioning feces with 31% and good drainage by making grase traps as much as 28%.

West Padang sub-district is a sub-district that has tourism potential, because in this sub-district there is a tourist attraction Puruih beach or what is known as Padang beach. As a tourist area, this sub-district still has problems with the availability of toilets and inadequate sanitation, as well as the habits of the people who still use the coast as a place to defecate. This habit will certainly cause new health problems later if you continue to let it. In addition, there are also many people who do not have their own MCK at home, and are forced to use public MCK for bathing and defecating and urinating. However, currently there are very few public toilet facilities in this area and if they do exist they are in a dilapidated condition. Added to this is the behavior of the surrounding community who do not take care of the public MCK facilities that have previously been built. In this study, researchers wanted to see changes in people's behavior after sanitation facilities were built in their area. Are they going to maintain the facilities that have been provided or are they the same as before, let the facilities be abandoned as before.
