Abstract

PDAM Ngagel 1 is a branch of PDAM Surya Sembada Surabaya under the auspices of the Surabaya Regional Owned Enterprise which focuses on providing clean water to the people of Surabaya. The raw water source used by PDAM comes from the Surabaya River, which is then processed into clean water. In providing clean water, an effective processing process is carried out so that good water quality is obtained. One of the indicators in determining the quality of the water produced is turbidity. This research aims to analyze the quality of production water produced by PDAM Ngagel 1 based on turbidity parameters as an indicator by paying attention to the influence of coagulant and polymer dosage. The water quality analysis was carried out using a simple linear regression test method with the help of Minitab 17 software. The results of this study showed that the turbidity level was influenced by the coagulant dose of 64.4% and the polymer dose of 61.1%, but had a negative value on the turbidity parameter. So the higher the dose of coagulant and polymer used, the lower the resulting turbidity value. This affects the quality of production water produced by PDAM Ngagel 1 which has met the quality standards set by the government based on PERMENKES No. 492 of 2010. PDAM Ngagel 1 ialah salah satu cabang dari PDAM Surya Sembada Surabaya dibawah naungan Badan Usaha Milik Daerah Surabaya yang berfokus pada penyediaan air bersih kepada masyarakat Surabaya. Sumber air baku yang digunakan oleh PDAM berasal dari Sungai Surabaya, yang kemudian diolah menjadi air bersih. Dalam penyediaan air bersih dilakukan proses pengolahan yang efektif sehingga didapatkan kualitas air yang baik, salah satu indikator dalam menentukan kualitas air yang dihasilkan yakni kekeruhan. Penelitian ini bertujuan untuk menganalisis kualitas air produksi yang dihasilkan oleh PDAM Ngagel 1 berdasarkan parameter kekeruhan sebagai indikator dengan memperhatikan pengaruh dosis koagulan dan polimer. Analisis kualitas air tersebut dilakukan menggunakan metode uji regresi linear sederhana dengan bantuan software Minitab 17. Hasil dari penelitian ini menunjukkan bahwa tingkat kekeruhan dipengaruhi oleh dosis koagulan sebesar 64,4% dan dosis polimer sebesar 61,1%, namun bermilai negatif terhadap parameter kekeruhan. Sehingga semakin tinggi dosis koagulan dan polimer yang digunakan maka semakin rendah nilai kekeruhan yang dihasilkan. Hal tersebut berpengaruh terhadap kualitas air produksi yang dihasilkan oleh PDAM Ngagel 1 yang telah memenuhi baku mutu yang ditetapkan oleh pemerintah berdasarkan PERMENKES No. 492 Tahun 2010.

Abstract

Clean water is river water that is managed by the Regional Drinking Water Company (PDAM) into water that meets predetermined regulations. According to the Regulation of the Minister of Health of the Republic of Indonesia Number 736/Menkes/PER/VI/2010 and the Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/PER/IV/2010, one of the parameters managed is to remove particles (pathogenic bacteria), remove residual chlorine levels and maintain the pH in the clean water. The purpose of this study is to analyze the correlation between residual chlorine and pH in clean water. This research is a study that uses data for 2 months in 2022, namely in August and September. The data was entered into Minitab 17 software with normality, correlation and simple linear regression test methods. The results obtained in this study are in August and September have almost the same results. The results in August have a very small correlation that can be said to have no correlation between residual chlorine and pH, while in September has a small correlation between residual chlorine and pH.

Abstract

The need for building materials, especially piled up soil, is increasing along with the increase in the construction of facilities and infrastructure. Under these conditions, mining activities for the extraction of piled up soil minerals are also increasing. These mining activities will certainly have an impact on the surrounding area from an economic, environmental and social perspective. Therefore, this research aims to find solutions for mining activities that have an impact on the surrounding area by managing, restoring and improving the quality of the environment and ecosystem so that they can function again according to their designation. This research method uses a descriptive approach by providing a detailed description of how the environmental management plan for the land after mining activities. In addition, this research is also aimed at projecting land conditions when mining activities take place with land conditions when environmental management has been carried out. The projected condition of the land will be processed using ArcGis and Global Mapper software. The post-mining environmental management plan is carried out based on the identification of potential mining impacts. Post-mining environmental management will be carried out using revegetation techniques and land arrangement according to the procedures for post-mining environmental management stages. Environmental management will be carried out every year in order to minimize environmental damage and stabilize green areas. This environmental management activity will restore the function of the mining land to its original state (before mining), namely to become rice fields and moor areas.

Abstract

Petrokimia Gresik is one of the largest and most comprehensive fertilizer companies in  Indonesia, playing a major role in the food security sector. The superior fertilizer production is  ZA II fertilizer. The existence of a strong concern lies in the emissions produced in the production  process where the presence of gas can trigger environmental impacts if not properly managed and  controlled. Therefore, through methodLife Cycle Assessment (LCA) is able to identify and assess  potential environmental impacts in PT Petrokimia Gresik's ZA II fertilizer production process.  Approach done byEndpoint divided into human health, ecosystem quality, and natural  resourcesRecipe 2016. As a support for the identification carried out, software will be used in the  form of Open LCA type 1.11.0 and SimaPro type 9.4.0.2. The studies obtained show that there is  a unit process that is produced with the greatest impact on the drying unit system (drying) and  cooling (cooling) due to the causes of the chemicals used and the emission content released in the  form of ammonia (NH3) and carbon dioxide (CO2). With this impact, it is necessary to carry out  alternative solutions to reduce the risk of impacts that occur in the ZA II fertilizer production  process.
