Abstract

Flood events are often inundated rice fields and can cause flooding to surrounding areas (the lower reaches of the river) should not be underestimated (just blame the rainfall factor alone), but should be seen also internal factors of the techniques of rice cultivation in paddy fields. The purpose of research/study was to analyze the effect of flooding on the cultivation of paddy rice to infiltration and provide alternative solutions cultivation techniques to reduce flooding. The research method in this study is a survey method with the quantitative approach. Techniques flooding in paddy rice cultivation, especially irrigated cropping pattern rice 3 times a year have resulted in the formation of plow layer tread that is waterproof (hardpan). Waterproof coating that forms on the floor of paddy (rice surface) cannot infiltrate rainwater so that if there is a high-intensity rainfall in the rainy season, rice cannot hold the rain water will overflow and cause flooding to the area around the rice fields. Techniques inundation in lowland rice cultivation resulted in flooded paddy rice growth period in a rather long time (over 2 months), so that the aggregate soil is loose and prone to erosion and landslide potential. Anticipation of floods caused by wetland can be done by making the high rice fields higher than the height of the floodwaters that ever happened to the rice field and lowering the height of standing water in the paddy fields.

Abstract

Mangrove restoration through planting activities has been carried out on the coast of Cilamaya, Karawang, West Java. The planting activities were focused on the Tangkolak and Pasir Putih areas. Then, this study aims to map the mapping of mangrove cover in the Tangkolak and Pasir Putih restoration areas. The mapping method used for mapping is a Geographic Information System (GIS). The results showed that in Pasir Putih the area of mangrove restoration was 0.347 km2, residential areas were 0.243 km2, and 2.295 km2 for paddy fields or ponds. While in Tangkolak the area of mangrove restoration is 0.46 km2, settlements are 0.256 km2, and 2.413 km2 for paddy fields or ponds. The comparison of the mangrove restoration area between Tangkolak and Pasir Putih is 1.32 : 1. It is estimated that the potential carbon stock in the restoration area were ranging from 84 ton/ha (95%CI: 77-91 ton/ha) to 92 ton/ha (95%CI: 88-96 ton/ha). From the results of the study, it can be concluded that there is mangrove cover with potential carbon stocks resulting from the restoration of Tangkolak and Pasir Putih.

Abstract

Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.
