Abstract

In smallholder cacao plantations, the protective crops used varied, so they have different effects on splash erosion. The management of land cover with a canopy of cacao and shade trees on cacao fields, aims to control of splash erosion. This study was conducted by directly measuring the magnitude of splash erosion under several levels of canopy cover. The magnitude of splash erosion was determined by measuring the depth of the eroded soil using the bottle cap method. The measurements were carried out every rain event (46 rain events with rainfall varied from 0.28 to 97.04 mm). The canopy cover level was determined by analyzing the images taken using a digital camera. The images were processed by Matlab software with closure approach. The data were analyzed by regression analysis to determine the relationship between canopy cover level and the depth of splash erosion that occurred. The results showed that the level of canopy cover influence the depth of splash erosion. In addition, this study indicates that the level of splash erosion not only influenced by the level of closure and rainfall, but also strongly influenced by the size of the leaf cover. Keywords: Cacao plantation, Canopy cover, Regression analysis, Splash erosion.

Abstract

Dependence on fossil fuels and limited access to electricity and clean water are challenges to agricultural productivity in many rural areas of Indonesia, including Campaga Village. This study aims to plan an appropriate water energy conversion (pico-hydro) system to meet the operational energy needs of agriculture, particularly irrigation pumps and lighting. The planning began with measuring the potential of resources (discharge, head) and analyzing energy needs based on agricultural applications. The measurement results showed an average discharge of 0.134 m³/s with an effective head of 10.5 m, with the potential to generate mechanical power for pumps of 3.9 kW and electrical power of 2.2 kW. The needs analysis confirmed that this potential is more than sufficient to power one irrigation pump unit (~3 kW) and light 21 road lighting points (0.63 kW). The technical planning recommends the use of a crossflow turbine and a standard AC generator in accordance with the principles of appropriate technology: simple, locally maintainable, and directly integrated with agricultural needs. The conclusion of this study shows that the designed pico-hydro system is not only technically feasible but also has the potential to become strategic supporting infrastructure to improve irrigation water resilience, extend farming hours, and ultimately empower the economy of agrarian rural communities.
