Prototipe sekat kanal berbasis komposit karet alam telah dibangun di Desa Sungei Rengit, Sumatera Selatan. Validasi pengembangan produk dilakukan dengan melakukan pengujian sifat fisika dan morfologi komposit karet sebelum dan setelah aplikasinya di lapangan. Hasil pengujian fisika komposit karet sebelum dan setelah diaplikasikan di lapangan relatif stabil, dengan nilai penurunan sifat fisika vulkanisat yang berkisar 20% setelah direndam pada suasana asam air gambut dan asam sulfat baik di laboratorium maupun di lapangan. Penurunan tersebut diakibatkan menurunnya interaksi antara matriks karet dan partikulat-pengisi sesuai hasil pengamatan morfologi komposit karet.
