Pemonitoran intensif beberapa nutrien dalam Sungai Sarawak di Kuching, Sarawak, Malaysia = Intensive monitoring of a few nutrients of the Sarawak River at Kuching, Sarawak, Malaysia

The variation of several nutrients and water quality parameters in Sarawak River was examined by intensive monitoring, i.e. four times in the morning and also four times in the afternoon. The sampling stations selected were at the Waterfront of Kuching town and at Batu Kitang upstream of the Sarawak...
