Libriyanto, Ananta Dwi and Dr. Ir. Zaenal Kusuma (2023) Kajian TSS (Total Suspended Solid ) dan TDS (Total Dissolved Solids) Air Irigasi pada Daerah Irigasi di Kabupaten Sukoharjo. Sarjana thesis, Universitas Brawijaya.
Abstract
Kondisi penggunaan lahan di Kabupaten Sukoharjo yang digunakan pada berbagai sektor memberikan dampak pada kualitas air. Adanya buangan limbah dari kawasan pemukiman, industri, pertanian serta kejadian erosi berdampak terhadap penurunan kualitas air irigasi. Kondisi kualitas air irigasi secara fisik dapat dilihat dari tingkat kekeruhan. Mengetahui tingkat kekeruhan air dapat dilakukan dengan pengujian parameter TSS (Total Suspended Solid) dan TDS (Total Dissolved Solids). Tujuan dari penelitian ini adalah untuk mengetahui perubahan nilai kandungan TSS dan TDS pada air irigasi yang dimanfaatkan untuk kebutuhan irigasi pertanian. Penelitian ini dilaksanakan mulai bulan Juli sampai bulan November 2022 di jaringan irigasi pada lima lokasi pengamatan di Kabupaten Sukoharjo. Lokasi pengambilan sampel diberi kode A, B, C, D dan E memiliki jarak berturut turut 1,3 km, 1,9 km, 5,4 km, 4,9 km, dan 6,5 km dari aliran sungai Bengawan Solo. Penelitian ini menggunakan metode survei dan pengambilan langsung sampel air di jaringan irigasi. Penentuan lokasi pengambilan sampel air mempertimbangkan kondisi irigasi terkait dengan kestabilan debit saat survei dan jarak dari aliran sungai Bengawan Solo ke titik pengambilan sampel air. Parameter kualitas air meliputi TSS dan TDS yang diambil setiap dua minggu sekali pada tiga kali periode atau selama enam minggu dengan mengambil sampel air sebanyak 1 liter di setiap lokasi. Analisis kondisi kelerengan di Kabupaten Sukoharjo dilakukan dengan analisis pada peta kelerengan. Analisis kualitas air dilakukan di laboratorium lingkungan Perum Jasa Tirta 1 Kota Surakarta. Analisis data TSS dan TDS dilakukan perbandingan dengan baku mutu air nasional pada peraturan pemerintah Republik Indonesia nomor 22 tahun 2021. Kualitas air yang dilihat dari parameter TSS cenderung tinggi di lokasi A dan B. Lokasi A memiliki nilai TSS pada periode awal, tengah dan akhir berturut turut 168 mg/L, 483 mg/L, dan 290 mg/L, di lokasi B 122 mg/L, 33 mg/L, dan 667 mg/L. TDS cenderung tinggi di lokasi A, B, dan C. Lokasi A memiliki nilai TDS pada periode awal, tengah dan akhir berturut turut 172 mg/L, 218 mg/L dan 226 mg/L, di lokasi B 331 mg/L, 294 mg/L dan 318 mg/L, di lokasi C 139 mg/L, 296 mg/L dan 307 mg/L. Kecenderungan kandungan TSS dan TDS yang tinggi di lokasi A, B, dan C dikarenakan lokasi tersebut memiliki penggunaan lahan yang cukup beragam seperti kawasan perkotaan, pemukiman, industri dan pertanian. Lokasi A, B, dan C yang berada di bagian hilir juga menjadi salah satu faktor kecenderungan TSS dan TDS yang tinggi karena adanya akumulasi air yang mengalir mulai dari hulu aliran sungai Bengawan Solo.
English Abstract
The condition of land use in Sukoharjo Regency which is used in various sectors has an impact on water quality. The existence of waste disposal from residential, industrial, and, agricultural areas and erosion events has an impact on reducing the quality of irrigation water. The condition of the quality of irrigation water physically can be seen from the level of turbidity. Knowing the level of water turbidity can be done by testing the TSS (Total Suspended Solids) and TDS (Total Dissolved Solids) parameters. The purpose of this study was to determine changes in the value of TSS and TDS content in irrigation water used for agricultural irrigation needs. This research was carried out from July to November 2022 in irrigation networks at five observation locations in Sukoharjo Regency. The sampling locations were coded A, B, C, D, and E, having distances of 1.3 km, 1.9 km, 5.4 km, 4.9 km, and 6.5 km from the Bengawan Solo river, respectively. This study used a survey method and direct sampling of water in irrigation networks. The determination of the water sampling location takes into account irrigation conditions related to the stability of the discharge during the survey and the distance from the Bengawan Solo river to the water sampling point. Water quality parameters include TSS and TDS taken every two weeks for three periods or for six weeks by taking 1 liter of water sample at each location. Analysis of slope conditions in Sukoharjo Regency was carried out by analyzing the slope map. Water quality analysis was carried out at the environmental laboratory of Perum Jasa Tirta 1, Surakarta City. Analysis of TSS and TDS data was carried out in comparison with the national water quality standards in the government regulation of the Republic of Indonesia number 22 of 2021. Water quality as seen from the TSS parameter tends to be high at locations A and B. Location A has TSS values in the early, middle, and late periods of 168 mg/L, 483 mg/L, and 290 mg/L respectively, at location B 122 mg /L, 33 mg/L, and 667 mg/L. TDS tended to be high at locations A, B, and C. Location A had TDS values in the early, middle, and late periods of 172 mg/L, 218 mg/L, and 226 mg/L, respectively, at location B 331 mg/L, 294 mg/L, and 318 mg/L, at location C 139 mg/L, 296 mg/L and 307 mg/L. There is a tendency for high TSS and TDS content in locations A, B, and C because these locations have quite a variety of land uses, such as urban, residential, industrial, and agricultural areas. Locations A, B, and C which are downstream are also a factor in the tendency for high TSS and TDS due to the accumulation of water flowing from upstream of the Bengawan Solo river.
