Sungai Lanangan merupakan bagian hulu Sungai Bengawan Solo yang terletak di Desa Daleman, Kecamatan Tulung, Kabupaten Klaten. Jenis limbah seperti limbah domestik, industri, pertanian, perikanan dan peternakan telah mencemari Sungai Lanangan. Limbah organik dari industri tepung aren dan mie soun yang dibuang di Sungai Lanangan mencapai 50 ton limbah per hari. Hal tersebut menyebabkan perubahan kualitas air dan komposisi fitoplankton di Sungai Lanangan.Penelitian ini dilakukan dari bulan Januari - Februari 2018 di Sungai Lanangan. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan dan komposisifitoplankton serta mengetahui kualitas perairan berdasarkan struktur komunitas fitoplankton di Sungai Lanangan tersebut. Penelitian ini menggunakan metode survei denganpengambilan sampel menggunakan metode purposive sampling. Frekuensi pengambilan sampel dilakukan setiap 1 minggu sekali selama 3 minggu. Sampel diambil dari 3 stasiun, dimana stasiun 1 dengan karakteristik perairan terbuka; Stasiun 2 dengan karakteristik dekat industri pengolahan tepung aren; dan stasiun 3 dengan karakteristik dekat dengan daerah budidaya air tawar.Hasil penelitian didapatkan 11 genera fitoplankton yaitu dari kelas Bacillariophyceae (4 genera), Cyanophyceae (2 genera), Chrysophyceae (1 genus), Ulvophyceae (2 genera), Zygnematophyceae (1 genus) dan Chlorophyceae (1 genus). Kelimpahan rata-rata fitoplankton tertinggi terdapat pada stasiun 2 dengan kelimpahan 1.989 ind/l yang didominasi oleh genus Oscillatoria. Indeks keanekaragaman rata-rata pada setiap stasiun adalah 1,68 pada stasiun 1; 1,63 pada stasiun 2; dan 1,52 pada stasiun 3. Dari hasil indeks keanekaragaman yang didapatkan tersebut menunjukkan kisaran nilai antara 1,52 hingga 1,68 yang berarti bahwa kualitas perairan Sungai Lanangan tercemar ringan.  Lanangan river is one upstream of Bengawan Solo river which located at Daleman, Tulung, Klaten. types of waste such as domestic waste, industrial waste, agriculture, fishery and animal husbandry polluted Lanangan river.
