The research location that is in Afdeling 3 PTPN XIII Mount Meliau Meliau District of Sanggau. This study aims to predict the magnitude of the erosion and the amount of erosion that can still be tolerated. The method used in this study was calculated using the USLE by knowing the value of the R factor, K, L, S, C and P which are the root causes of erosion in the area of oil palm plantations in the study sites. Further erosion of values that can be tolerated in comparison to the predicted value erosion. Having compared the predictive value of the erosion of the value erosion that can be tolerated, it is necessary to do the conservation measures recommended.The results of this study found that the rate of erosion prediction (A) reached 140.16 to 9737.28 tons / ha / year. Value erosion prediction that can be tolerated (Etol) ranged from 48.22 to 32.13 tonnes / ha / year. In Ult4 land value (A) is greater than the value of Etol with moderate erosion hazard level, while on land Ult18, Ult24, Ult36 value (A) is greater than the value of Etol with severe erosion hazard level. Planning and prevention of erosion is the appropriate planting bench terracing of good construction. Special to land Ult4 and Ult18 can in recommend also with planting LCC and making the porch kontruksi was.

Jetak watersheds is already in a critical state and undergo changes caused by industrial waste, household. This research aimed to study the characteristics of the Jetak watershed. Jetak sub watershed has an area of 18734.27 hectares located in District Dedai Sintang. This study was conducted at two observation points that were on the downstream and upstream conducted on 6 consecutive days and subsequently analyzed in the laboratory TSS Land Quality and Health Faculty of Agriculture, University of Tanjungpura. The results showed that the pattern of Jetak’s river pipeline that was dendritic pattern and it shaped like a bird feather. IKD value was 0.0143 km / km2 and included the low category while the transverse profile of the river at the downstream and the upstream parabolic square shaped. Orde the river consisted of 2 ordes and water quality with an average pH value in the upstream was 6.01 and on the downstream was 6.46, the temperature on the upstream side had an average value was 27,90C and downstream has an average value was 27,70C, the brightness on the upstream side has an average value was 75.5 cm and the downstream section has an average value was 96.08 cm. Flow rate at the downstream has an average value was 7.418 m3 / sec and the upstream section was 0.790 m3 / sec. Discharge curve (r) of downstream was 0.084 and upstream was 0.746 with R2 downstream was 0,007 and the upstream was 0.557. The concentration of suspended sediment downstream had an average vaue was 9.5 mg / liter and upstream was 8.33 mg / liter. Downstream sediment discharge has an average was 6.13 tons / day and upstream was 0.57 tons / day. Arch sediment downstream (r) is 0.864 with R2 was 0.746 and on the upstream side (r) was 0.031 with R2 was 0.001.

Lokasi penelitian yakni di Afdeling 3 PTPN XIII Gunung Meliau Kecamatan Meliau Kabupaten Sanggau. Penelitian ini bertujuan untuk memprediksi besarnya erosi yang terjadi dan besarnya erosi yang masih dapat ditoleransi. Metode yang digunakan dalam penelitian ini dihitung menggunakan metode USLE dengan mengetahui nilai dari faktor R, K, L, S, C dan P yang merupakan faktor penyebab terjadinya erosi pada areal perkebunan kelapa sawit di lokasi penelitian. Selanjutnya nilai erosi yang dapat ditoleransi dibandingkan dengan nilai prediksi erosi. Setelah dibandingkan nilai prediksi erosi dengan nilai erosi yang dapat ditoleransi, maka perlu dilakukan tindakan konservasi yang direkomendasikan. Hasil penelitian ini didapatkan bahwa prediksi laju erosi (A) mencapai 140,16 sampai 9737,28 ton/ha/tahun. Nilai prediksi erosi yang dapat ditoleransi (ETOL) berkisar antara 48,22 sampai 32,13 ton/ha/tahun. Pada lahan Ult4 nilai (A) lebih besar dari nilai Etol dengan tingkat bahaya erosi sedang, sedangkan pada lahan Ult18, Ult24, Ult36 nilai (A) lebih besar dari nilai Etol dengan tingkat bahaya erosi sangat berat. Perencanaan dan penanggulangan bahaya erosi yang sesuai adalah pembuatan teras bangku kontruksi baik. Khusus untuk lahan Ult4 dan Ult18 dapat direkomendasikan juga dengan penanaman LCC dan pembuatan teras kontruksi sedang.Katakunci : Prediksi erosi USLE, Kelapa sawit, Perkebunan PTPN XIII

Marine and Coastal Area which + 28 % of total areas in Kubu Raya Distric has potentially profit areas for palawija crops, e.a: corn, soybeans, cassavas, and sweet potatoes crops. but not yet to be specified in local uniqueness land characteristics to reach more larger productivity. These research is proposed to its clustering through Spatial Analysis with GIS, Principal Component Analysis (PCA). About 3 indexes from 13 land characteristics has been clustered, (1) K, Na, Ca, Mg and Base Saturation, have positive correlation (coefficient determination = 0,92) to corn and soybean crops productivity. (2) Cation Exchange Capacity and Silt Fractions have negative correlation (coefficient determination = 0,92) to cassava productivity. And (3) Phosfor indexes have positive correlation (coefficient determination 0,91) to sweet potatoes crops productivity
