Abstract

Ciapus Sub Watershed is part of the Cisadane watershed which passes through 3 (three) sub-districts in Bogor Regency, namely Dramaga District, Ciomas District, and Tamansari District. From 2011 to 2020 housing construction in Dramaga, Ciomas and Tamansari sub-districts increased. High enough rainfall and continuous land changes will result in water infiltration not functioning properly and will cause an increase in surface runoff. Therefore, it is necessary to know how much influence changes in land cover have on the runoff discharge of rainwater in the Ciapus sub-watershed. The purpose of this study was to identify changes in land cover in the Ciapus sub-watershed and to determine the magnitude of the increase in runoff due to changes in land cover in the Ciapus sub-watershed. The results of the analysis of the Ciapus sub-watershed have 8 types of land cover, namely water bodies, primary dry land forest, secondary dry land forest, gardens, dry land agriculture, mixed dry land agriculture, rice fields and settlements. The biggest change in land cover area between 2011 and 2020 is the increase in residential area of ​​2441.59 ha. Meanwhile, dry land agriculture experienced the largest reduction in area of ​​1288.68 ha. Based on the calculation of runoff discharge using the rational method, the amount of discharge that occurred in 2011 was 153.31 mm/second while in 2020 it was 214.99 mm/second

Abstract

In activities, the community produces waste so that the production of waste is increasing over time. For this reason, it is necessary to carry out effective and efficient waste management. This study aims to determine the strategy of waste management managed by the Environmental Agency at the Galuga Landfill, Galuga Village, Cibungbulang District, Bogor Regency, in this study used descriptive research methods using a qualitative approach. The informants in this study were the Waste Management Section, the Head of the Galuga Landfill, Garbage Transport Officers, Community Leaders, and local residents. The collection of data and information is done by means of interviews, and documentation. The data analysis technique used is SWOT analysis by taking into account all internal and external aspects of the organization, namely strengths, weaknesses, opportunities, and threats. Based on the results of the SWOT calculation, the Galuga solid waste subsector is in quadrant one, namely internal and external strong, with the result that the value of the difference between strengths and weaknesses on internal factors shows a positive value and the value of the difference between opportunities and threats on external factors also shows positive, so the strategy what will be developed to overcome strategic issues that arise is an aggressive strategy in implementing landfill management, such as establishing a waste zoning pattern, improving services and efforts to reduce waste through 3R.

Abstract

Coastal areas are characterized by complex dynamics between freshwater entering through the estuary from land and seawater from open water. This study aims to calculate the salinity anomaly found on the sandy coast of Mayang, estimate the number of fractions and the volume of mass transport of fresh water entering the waters through the river flow and measure the total dissolved solids (TDS) in the west season. Water mass characteristics data collection using Water Checker. The determination of 17 data collection stations is assumed to be representative in representing the overall condition of the research location. The results of the anomaly salinity calculation show the low anomalous salinity values that are distributed horizontally on the coast. The distribution of salinity as anomaly values transversely on lines 1 to 4 ranges from -1 to -15. Freshwater fraction is concentrated as far as 1.16 km from the coast of Pasir Mayang with concentration values ranging from 0.44% to 0.13%. The mass transport of fresh water in the Pasir Mayang coastal waters is 1,130 m3s -1. The value of the transport volume of fresh water depends on rainfall and the flow of fresh water through rivers and then into sea waters. The total dissolved solids at the study site at each station ranged from 7.88 ppm to 17.8 ppm.

Abstract

Cikidang Fishery Port is one of the ports with serious abrasion and sedimentation problems. Seawater abrasion significantly affects some coastal areas that lack breakwater protection. Seawater abrasion causes the shoreline to recede further into the land, thereby narrowing the operational area of the coast. Not only that, harbour areas that are both protected and unprotected by breakwater also experience problems regarding water areas caused by ocean currents, tides, and large waves that lead to sedimentation. Sediment reduces the depth of harbour dock waters, making it impossible for ships to dock. As a fishing port that contributes significantly to the local economy, the Cikidang Fishery Port (CFP) necessitates analysis and solutions to address the issues of sedimentation and abrasion. References for this study used both primary and secondary data. We used a GPS handheld to measure the coastal area, and we conducted comparative studies using satellite images to gather secondary data. This will calculate the effective duration of the dredging process, enabling precise execution and minimizing the associated expenses.
