Opis:: This study aims to determine what is the influence of the density of mangroves on the rate of coastal sediment transport and abrasion that occurred in the Sikakap Coastal area of Mentawai Island district. The research method used is the quadratic transect method and the sediment trap method. The type of mangrove vegetation that dominates in the Sikakap Coastal area of Mentawai Island district is Avicennia marina. Tree level mangrove density at Station I is 1,450 stands / ha and categorized as good, while the tree level mangrove density at Station II is 900 stands / ha and categorized as heavily damaged mangrove forests. The relationship between mangrove density and transport sediment rate in Sikakap Coastal, Mentawai Island district shows a negative correlation with the value -1, meaning that when mangrove density is high, the transport sediment rate will be low, and vice versa, when mangrove density is low, the transport sediment rate will be high.

Opis:: The objectives of developing oil palm plantations should feasible economically and without causing massive erosion. This research proposes soil and water conservation strategies that are ideal and optimal for oil palm cultivation depending on land capability class. The conservation test for plants was performed according to land capability classes on a plot measuring 22 m × 4 m. Runoff and erosion rates were measured using Multislot Divisor Method. Nutrient leaching was analysed based on the content of C-organic (Ctot) (Walkley–Black method), total nitrogen (Ntot) (Kjeldahl method), P-available (Bray-1 method) and K2O (extraction with 1N NH4OAc at pH 7.0). From the results, land capability class III, cover crops (soybean) + manure (P3) treatment effectively reduced runoff and soil erosion (22.63 m3∙ha–1∙y–1 and 13.04 Mg∙ha–1∙y–1), as well as nutrient leaching, compared to other treatments. Furthermore, sediment trap + cover crop + manure (P3) controlled runoff, erosion and nutrient leaching on land capability class IV, producing the lowest runoff (129.40 m3∙ha–1∙y–1), soil erosion (11.39 Mg∙ha–1∙y–1), C-organic (1.3%), and P (1.95 mg kg–1). Soil conservation treatment significantly reduced erosion and runoff (p < 0.05) on land capability class VI. The bench terrace + cover plants + manure treatment-controlled runoff, erosion, and soil nutrient leaching.

Opis:: A sediment trap with bamboo materials can be utilized as one alternative of eco-friendly technology to reduce the erosion that occurred on agricultural land. This study aims to determine the most efficient form of that sediment trap in the field. Location study is in the Tulungrejo Village, Batu, Indonesia, which has andosol soil type and 35 cases of a landslide in 2013. Three forms of sediment traps were used (square, trapezoidal, and stratified type) with the purpose to find the most effective form. It is obtained that the most effective sediment trap is a stratified form with the 31.91% effectiveness or able to withstand sediment of 25.02 kg, while the adequate number is two pieces with the ability to withstand the most considerable sediment of (91.70%). Therefore this stratified form of sediment traps is effective in erosion prevention on agricultural land in the study area. For further development, it is required to test out the variations of the contents in a broader area with a more varied level of the slope.
Pułapka z bambusu do wychwytywania osadów może być używana na terenach rolniczych do ograniczenia erozji jako jedna z alternatywnych technologii przyjaznych środowisku. Miejscem badań była wieś Tulungrejo, Batu w Indonezji. W badaniach terenowych podjęto próbę określenia najbardziej efektywnej pułapki spośród trzech form: kwadratowej, trapezoidalnej i warstwowej. Najlepsza okazała się pułapka warstwowa o skuteczności 31,91%, zdolna zatrzymać osad o masie 25,02 kg. Zestawienie dwóch takich pułapek dało skuteczność 91,70%. Warstwowa forma pułapek jest więc skuteczna w zapobieganiu erozji z terenów rolniczych na obszarze prowadzonych badań. W przyszłych pracach należy przeprowadzić podobne testy na innych obszarach o bardziej zróżnicowanej rzeźbie terenu.
