One type of ion that can be known is the sulfate ion. Sulfate ions are one of the main anions that appear in water naturally. Sulfate is one of the important ions in water availability because of its important effect on humans when it is available in large quantities. The maximum limit of sulfate in water is around 250 mg / L for human-consumed water. This study uses qualitative analysis to determine whether water in the Jakabaring Sport City Palembang region contains sulfate ions or not. Samples taken directly from five different points were reacted with HCl and BaCl2. The results obtained are the five positive water samples containing sulfate ions which are characterized by the formation of white deposits.</em></p> Desti Erviana, Annisa Widya Budaya, Silvi Hariani, Arriya Winda, Luffiya Yulia Sari ##submission.copyrightStatement## Wed, 16 Jan 2019 00:00:00 +0000 Analisis Kadar Klorida Air Sumur Bor Sekitar Tempat Pembuangan Akhir (TPA) II Musi II Palembang dengan Metode Titrasi Argentometri <p>The community around Tempat Pembuangan Akhir (TPA) II Musi II Kelurahan Karya Jaya still relying on borehole water to fulfill their daily needs. The existence of TPA around these community environments can have a negative impact, including an indication of contamination of borehole water. One of the water pollution that is suspected to occur due to contamination of leachate from TPA is over chloride level in borehole water. The present work aimed at determining chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya using Mohr argentometry titration method. The results showed chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya is 301.75 mg/L. Based on PerMenKes RI No.492/MENKES/SK/VI/2010 and PerMenKes RI No.416/MENKES/ PER/IX/1990, the maximum level of chloride for drinking water is 250 mg/L, while for clean water is 600 mg/L, so that it can be concluded that borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya can’t be used for primary needs, for example drinking and cooking needs, but borehole water can still be used for secondary needs such as bathing and washing.</p> Mifta Huljani, Nur Rahma ##submission.copyrightStatement## Wed, 16 Jan 2019 00:00:00 +0000 Analisis Kadar Zat Organik pada Air Sumur Warga Sekitar TPA dengan Metode Titrasi Permanganometri <p>Groundwater is one of the main alternatives for people to get clean water easily, because the construction is relatively easy. Therefore residents around the landfill use ground water. Final Disposal Site (TPA) is a place where waste has reached the final stage in its management. Well water around the landfill will usually be polluted by various chemicals that are harmful to the body, one of which is organic matter. Organic substances are substances that contain a lot of carbon. Examples are benzene, chloroform, detergent, and pentachlorophenol. High levels of organic matter indicate that the water has been polluted. Therefore, the determination of the level of organic matter in the samples of borehole water so that the quality can be known quality. To determine the level of organic matter in the sample of community drill well water, quantitative analysis was carried out using the permanganometric titration method. The principle of the permanganometric titration method is that organic matter can be oxidized with KMnO<sub>4</sub> in an acidic atmosphere by heating. The remaining KMnO<sub>4</sub> is reduced with excess oxalic acid. The excess oxalic acid is titrated again with KMnO<sub>4</sub>. Based on the results of the analysis, the levels of organic matter contained in well water samples amounted to 586.8 mg / L. So it can be concluded that the sample of community drill well water is not suitable for drinking, because it does not meet the criteria of drinking water. The criteria for drinking water according to the Minister of Health of the Republic of Indonesia No.492 / MENKES / SK / VI / 2010 are not containing more than 10 mg / L of organic matter. This is because the amount of organic matter will result in increasing the population of microorganisms and can lead to the development of dangerous pathogenic bacteria in the human body, especially for the immune system.</p> Apriyanti Apriyanti, Ersy Monica Apriyani ##submission.copyrightStatement## Wed, 16 Jan 2019 00:00:00 +0000 Analisis Kandungan Fe (II) Air Selokan di Sekitar TPA II Kelurahan Karya Jaya Musi 2 Palembang dengan Metode Spektrofotometri UV-Vis <p>Telah dilakukan penelitian mengenai analisa kandungan Fe (II) air selokan disekitar TPA II kelurahan karya jaya musi 2 palembang dengan metode spektrofotometri UV-Vis. Penelitian ini dilakukan untuk mengetahui kandungan logam besi pada air lindi disekitar tempat pembuangan akhir menggunakan metode spektrofotometri UV-Vis. Hasil karakterisasi air lindi dengan spektrofotometri UV-Vis menunjukkan kandungan logam besi yang paling tinggi berada pada titik sampel 4 ke 4 sebesar 2.767 mg/I dengan rata-rata kandungan 0.7308 mg/I &nbsp;yang melebihi kadar baku mutu kualitas air sesuai dengan Peraturan pemerintah No.82 tahun 2001 bahwa kadar besi yang diperbolehkan dalam baku mutu kualitas air kelas I sebesar 0.3 mg/I.</p> Tria Wulandari, Sri Wahyuni ##submission.copyrightStatement## Wed, 16 Jan 2019 00:00:00 +0000 Penentuan Kadar Amonia (NH3) pada Limbah Cair K-34 dalam Rangka Pengendalian Pencemaran Lingkungan <p>Amonia bebas merupakan amonia yang tidak bereaksi sempurna dengan karbon dioksida pada saat proses pembuatan urea. <em>Free am</em><em>m</em><em>onia </em>tidak berikatan langsung dengan urea tetapi melekat dalam &nbsp;butirnya.

Salah&nbsp; satu&nbsp; komponen yang penting dalam deterjen cuci cair adalah surfaktan anionik. Berdasarkan SNI 06-4075-1996 tentang Deterjen Cuci Cair, syarat mutu kadar surfaktan anionik minimal sebesar 15% - 35%. Analisa kadar surfaktan anionik pada percobaan ini menggunakan metode Titrimetri. Prinsip dari metode titrimetri yakni, surfaktan anionik dalam contoh uji dihidrolisis dengan asam sulfat membentuk campuran kationik dan anionik. Surfaktan anionik yang berasal dari hasil reaksi antara etanol dengan asam sulfat yang menghasilkan sulfat etanol. Titrasi dengan asam sulfat sampai warna larutan berubah dari warna merah jambu sampai menjadi abu-abu kebiruan. Kadar surfaktan anionik yang diperoleh dari masing-masing contoh uji dari A-D secara berturut-turut adalah 17,43%; 7,64%; 8,89%; 8,64%. Kadar surfaktan anionik tersebut memenuhi syarat mutu batas minimal yakni 15%-35%.</p> Ika Candrika Wibisono ##submission.copyrightStatement## Wed, 16 Jan 2019 00:00:00 +0000 Penentuan Kadar Ammonia (NH3) pada Limbah Cair K-36 dalam Rangka Pengendalian Pencemaran Lingkungan <p>Penelitian ini bertujuan untuk mengetahui kadar ammonia (NH<sub>3</sub>) pada limbah cair K-36 PT.
