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

Wetland ecosystems are important habitats for many waterbird species, including the IUCN nearthreatened Sunda Teal Anas gibberifrons, a species that inhabit wetlands in Indonesia. Muara Angke is one of few remaining wetlands located in Jakarta and has potential as an important habitat for Sunda Teal. This study aims to assess and model suitable habitat for near-threatened Sunda Teal in remaining wetlands in Muara Angke in Jakarta, Indonesia. The study areas include an ecotourism park, the western and eastern parts of the Angke protected forest, and the wildlife reserve. Remote sensing data and geographic information system (GIS) analysis were employed to assess Sunda Teal’s habitat suitability. Some environmental variables negatively influencing habitat suitability for the species include the presence of fishponds and settlements, and represent anthropogenic disturbance. In contrast, variables that may positively influence the species include the occurrence of gastropod and crustacea, both groups being known as food resources, and mangrove cover. The highly and moderately suitable habitats were estimated to form 32.36% and 23.48% of the total wetlands, respectively. In contrast, 12.17% was considered unsuitable for Sunda Teal. The ecotourism park had the most unsuitable habitats. In contrast to the ecotourism park, the protected forest, followed by the wildlife reserve, had more moderately and highly suitable habitats.

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.
