Abstract

This study aims to map mangrove zoning and its relationship with salinity along the Cijulang River flow, Pangandaran Regency. The method used is a survey with a quantitative approach using purposive sampling techniques, focused on analyzing the structure of mangrove communities through important value indices (INP), diversity indexes, Evenness indices, and dominance indices. The results of the study showed that there were six species of mangroves, namely Aegiceras corniculatum, Avicennia marina, Bruguiera gymnorrhiza, Nypa fruticans, Sonneratia alba, and Rhizophora mucronata. Mangrove zoning is divided into three, namely the open zone (Station I, Batukaras Village), the central zone (Stations II and III), and the land zone (Station IV, Kondangjajar Village). Sonneratia alba has the highest INP value of 87%, while Bruguiera gymnorrhiza has the lowest INP value of 10%. Overall, the results of the study show that the community structure and mangrove zoning pattern in the Cijulang River are related to variations in the salinity level of the waters, sequentially found mangrove vegetation at high salinity values (6,3 ppt) to low (3 ppt) starting with the species Avicennia marina, Rizophora mucronata, Sonneratia alba, Aegiceras corniculatum, Bruguiera gymnorrhiza and Nypa fruticans.

Abstract

Lau Belawan River has a fish potential, including yellow-finned barb (Mystacoleucus marginatus. The objective of this study was to investigate the reproductive biology of the yellow-finned barb (Mystacoleucus marginatus, Valenciennes 1842) in the Lau Belawan River, North Sumatra Province. The research location consists of 3 stations. Fish samples were collected by capturing fish using a low-voltage backpack electrofishing unit.  Determination of the sex ratio is done surgically, then the results are tested using chi-square statistics, gonad maturity index obtained by comparing body weight with gonad weight, and estimation of the size of the first mature gonad using the Sperman-Karber method. The fish caught during the study amounted to 165 fish collected from 3 research stations: Namorih Village, where station 1 collected 146 fish; Kampung Tengah Village station 2, with a total catch of 148 fish; and Baru Ladang Bambu Village station 3, with samples collected of 222 fish. The Lau Belawan River habitat supports the existence of aquatic biota such as fish and plankton. The sex ratio of yellow-finned barb fish is balanced in November and December except in October, January, February, and March. Female fish mature gonads dominantly in November, December, and March, while males mature in October, January, and March. Spawning occurred every month, with peak spawning occurring in March. Male and female gonad mature yellow-finned barb fish are present at each station, indicating that the research station is a suitable habitat for spawning fish.

Abstract

Waste is a major environmental issue in PPP Tegalsari, one of the biggest fishing ports in Central Java. PPP Tegalsari is a slum, as shown by the copious amounts of trash around the port's main intersections, with a quick assessment to evaluate the PPP Tegalsari Area's waste conditions and management situation. Primary data was gathered through observation, questionnaires and waste calculation forms were used in surveys, and in-depth interviews were conducted with interview guides. On the other hand, reports from associated agencies, scientific publications, and government stakeholders were secondary data sources. The Rapid Assessment activities' outcomes from June 14–19, 2021, covered waste management, human resources, and infrastructure for waste processing.
