Sumber daya alam yang sangat dibutuhkan manusia adalah air. Ketersediaan air tawar atau air bersih mengalami kelangkaan seiring dengan pertumbuhan penduduk. Salah satu sumber air tawar yang menjadi perhatian adalah sungai. Penelitian ini bertujuan untuk mengetahui kondisi tutupan lahan, aktivitas masyarakat serta menganalisis kaitannya dengan kualitas perairan Sungai Subayang tahun 2017-2020. Penelitian ini dilaksanakan di wilayah Sub-sub Daerah Aliran Sungai (DAS) Subayang, Kecamatan Kampar Kiri Hulu, Kabupaten Kampar pada Juni-Agustus 2021. Data primer penelitian didapatkan melalui observasi lapangan dan wawancara. Data sekunder meliputi data tutupan lahan bersumber dari KLHK dan data pengkuran kualitas air Sungai Subayang 2017-2020 bersumber dari Tim Fresh Water and Fisheries WWF Indonesia- Central Sumatra. Sampel pengamatan dari bagian hulu ke hilir berada di desa Aur Kuning, Batu Songgan dan Tanjung Belit. Penentuan status mutu kualitas air sungai dianalisis menggunakan pendekatan Indeks Pencemaran (IP) berdasarkan Peraturan Menteri Lingkungan Hidup Nomor 115 tahun 2003, dan penentuan baku mutu berdasarkan Peraturan Pemerintah Nomor 22 Tahun 2021. Hasil penelitian menunjukkan bahwa berdasarkan parameter suhu, kecepatan aliran sungai (arus), kekeruhan, oksigen terlarut, dan pH dari tahun 2017-2020, air Sungai Subayang berada pada kualitas baik dengan Indeks Pencemaran (IP) berkisar 0,27-0,80 (memenuhi nilai baku mutu kelas 2). Kualitas perairan yang baik tersebut berkaitan dan dipengaruhi oleh kondisi tutupan lahan yang masih didominasi hutan (97-99,15%), praktek pemanfaatan hutan dan sungai berbasis kearifan lokal, serta mulai membaiknya pengelolaan limbah dan aktivitas MCK oleh masyarakat.

Penelitian pencarian agen tabir surya alami terus dikembangkan untuk mendapatkan agen tabir surya yang lebih aman. Tabir surya diperlukan untuk melindungi kulit dari bahaya sinar ultraviolet (UV). Sinar UV dapat bermanfaat bagi tubuh, namun menjadi berbahaya jika berlebih. Kemampuan suatu bahan dalam melindungi dari bahaya sinar UV biasa dinyatakan dalam sun protection factor (SPF). Penelitian ini bertujuan untuk mengetahui nilai SPF ekstrak metanol daun rambutan (Nephelium lappaceum). Penelitian ini nantinya dapat digunakan untuk menambah wawasan mengenai potensi daun rambutan untuk digunakan sebagai agen tabir surya alami. Proses ekstraksi menggunakan metode maserasi dengan pelarut metanol. Pengukuran nilai SPF dilakukan secara in vitro menggunakan metode spektrofotometri kemudian nilai absorbansi yang diperoleh dihitung menggunakan persamaan Mansur. Proses ekstraksi menghasilkan ekstrak pasta hitam kehijauan beraroma khas daun. Ekstrak metanol daun rambutan dengan konsentrasi 100, 200, 300, 400, 500, dan 1000 ppm memiliki kemampuan proteksi terhadap sinar UV, dinyatakan dalam nilai SPF berturut-turut sebesar 5,710; 10,398; 16,320; 20,920; 26,152; dan 37,983. Hasil yang berbeda dari tanaman yang sama dapat terjadi dikarenakan pengambilan bagian tubuh tanaman yang berbeda untuk diekstrak serta penggunaan jenis pelarut organik yang berbeda untuk proses ekstraksinya. Dalam penelitian ini, ekstrak metanol daun rambutan pada konsentrasi 100 dan 200 ppm memiliki kemampuan proteksi minimal, konsentrasi ekstrak 300-500 ppm memiliki kemampuan proteksi sedang, sedangkan konsentrasi ekstrak 1000 ppm memiliki kemampuan proteksi tinggi
