Analisis perubahan pemanfaatan lahan sangat penting karena pemanfaatan lahan tersebut bersifat dinamis. Secara berkala pemanfaatan lahan akan dipengaruhi oleh faktor alam dan karakter manusia di dalamya. Analisis vegetasi di sempadan sungai dapat dijadikan sebagai salah satu indikator dalam menentukan kualitas sempadan di sekitar sungai. Penelitian ini bertujuan untuk mengetahui komposisi vegetasi sempadan DAS Cilaja berdasarkan pemanfaatan lahan yang berbeda. Penelitian ini dilakukan di lokasi perkebunan kopi, persawahan dan pemukiman menggunakan Metode Kuadran dengan penentuan plot pengambilan sampel secara Stratified Random Sampling. Pada setiap lokasi dipasang 8 kuadran secara berseling. Komposisi vegetasi sempadan DAS Cilaja di lokasi perkebunan kopi didominasi oleh Ageratina riparia (INP=36.94), Coffea arabica, (INP=22.33) dan Alternanthera sp. (INP=20.71). Pada lokasi persawahan didominasi Calliandra calothyrsus (INP=32.75), Tithonia diversifolia (INP=15.91) dan Synedrela nodiflora (INP=15.79). Pada lokasi pemukiman didominasi oleh Syngonium sp. (INP=19.57), Musa paradisiaca (INP=15.13) dan Hyptis capitata (INP=12.32). Dapat disimpulkan secara umum bahwa keterlibatan pengelolaan lahan dapat merubah jumlah dan jenis vegetasi di sekitarnya.;--- Analysis of land use change is very important because the land use is dynamic. Periodically land use will be influenced by natural factors and human characters in it. Analysis of vegetation in river border can be used as one of the indicators in determining the quality of border around the river. This study aims to determine the vegetation composition of Cilaja river basin based on different land utilization. This research was conducted at coffee plantation location, rice field and settlement using Quadrant Method with determination of sampling plot in Stratified Random Sampling. Bound vegetation of Cilaja watershed at coffee plantation area is dominated by Ageratina riparia (IVI=36.94), Coffea arabica, (IVI=22.33) and Alternanthera sp. (IVI=20,71). In the rice field location is dominated by Calliandra calothyrsus (IVI=32,75), Tithonia diversifolia (IVI=15,91) and Synedrela nodiflora (IVI=15,79). The location of the settlement is dominated by Syngonium sp. (IVI=19,57), Musa paradisiaca (IVI=15,13) and Hyptis capitata (IVI=12,32). It can be concluded generally that the involvement of land management can change the amount and type of vegetation around it.
