The current condition of the Karangantu Archipelago Fisheries Port (PPN) is still considered unfavorable because the operational area of ??the port waters looks dirty and shabby. There are many ships that are no longer used in the Karangantu PPN operational area. Based on the results of interviews with PPN Karangantu officers, there are several things that cause ships to be abandoned in the operational area of ??PPN Karangantu waters, including the age of the ship, costs or capital, and human resources. Abandoned ships that are not immediately handled will result in obstacles to the flow of water traffic at the port and create a risk of collision for other ships passing by. Therefore, web-based mapping of abandoned ships (WebGIS) is needed in the operational area of ??PPN Karangantu waters. It is hoped that the results of this abandoned ship mapping can be used by the port to report abandoned ships to the center so that they can immediately take action to transport the abandoned ships. With the existence of WebGIS mapping abandoned ships, the port does not need to go directly to the field to find the location of abandoned ships because the information can be accessed via the web that has been created. Data collection on coordinate points was carried out by field survey and tagging using the GPS Map Camera application. The research results show that there are 74 abandoned ships in the Karangantu PPN operational area.

Transportasi sedimen laut adalah proses pergerakan sedimen di laut yang terjadi karena adanya gaya-gaya yang bekerja pada sedimen tersebut. Sedimen laut dapat berupa pasir, dan batuan kecil yang terbawa oleh arus laut, gelombang, dan angin. Muara Bajulmati atau muara Sungai Panguluran memiliki sedimentasi yang halus dan di dominasi oleh pasir.  Pada kondisi musim barat rendah total load sedimen dari arah vertikal memiliki besaran hingga, 0.00112m^3/s/m. Hal tersebut memuat bagian muara mengalami erosi dan sedimentasi. Pemodelan ini bertujuan untuk mengetahui pola sedimen serta melihat pengaruh sedimen terhadap Pantai serta muara. Pemodelan ini menggunkan software MIKE21 dengan modul Hidrodinamik serta Sand Transport

The Karangantu Archipelagic Fisheries Port, commonly referred to as PPN Karangantu, provides a venue for business activities in the field of fisheries. These business activities are carried out by the fishermen of the Boat Lift Net. The Boat Lift Net captures small pelagic fish, and the catch is distributed by the fishermen of the Boat Lift Net at PPN Karangantu to fish traders outside the Karangantu location. This expands the distribution of the marketing of the catch from PPN Karangantu, as it is not only marketed at the Karangantu Fish Auction (TPI Karangantu). Therefore, the objective of this research is to illustrate the map of the distribution locations of the marketing of the catch from the Boat Lift Net landed at PPN Karangantu. Subsequently, it aims to identify the distribution channels for the marketing of the catch from Boat Lift Net at PPN Karangantu. To achieve these objectives, this research uses a qualitative descriptive approach and Geographic Information System (GIS) with remote sensing methods. As a result, it is found that PPN Karangantu has 4 distribution channels and there are 11 distribution locations for the marketing of the catch from the Boat Lift Net
