Abstract

Water is a source of life for humans. The need for water often makes humans unaware that their activities can trigger the entry of pollutants into water bodies. These pollutants can degrade river water quality. Water quality refers to the condition of water based on its physical, chemical, and biological characteristics. Water quality can be analyzed based on the presence of aquatic organisms intolerant to pollutants. The objective of this study is to describe the water quality of Paneki River based on the presence of Macrozoobenthos organisms as water bioindicators. This research is a quantitative descriptive study using a line transect sampling technique at three purposively selected stations. The results showed that Macrozoobenthos found belonged to 11 families: Gecarcinucidae, Coenagrionidae, Baetidae, Physidae, Hydropsychidae, Heptageniidae, Gomphidae, Lumbricidae, Palaemonidae, Philopotamidae, and Naucoridae. The calculation of water quality analysis based on the Family Biotic Index at station I was 4.07, and station II was 4.09, indicating both stations are classified as excellent water quality with slight pollution from organic matter. Station III scored 4.42, classified as good water quality with some pollution from organic matter.

Abstract

This study aims to determine the species diversity of mangrove crabs from the family Ocypodidae in the mangrove area of Lalombi Village, Banawa Selatan District, Donggala Regency. The type of research used is descriptive quantitative. The study was conducted in the mangrove area of Lalombi Village, Banawa Selatan District, Donggala Regency, from February to April 2025. The sampling location was determined using a purposive sampling method, considering mangrove vegetation density and site accessibility. Crab samples were collected directly using the hand collection method during low tide. The population and samples in this study consisted of all Ocypodidae mangrove crab species found at the research site. Data analysis was performed by calculating the Shannon-Wiener diversity index (H') to determine the level of species diversity. A total of five crab species were found: Uca dussumieri, Uca perplexa, Uca cryptica, Uca jocelynae, and Uca coarctata. The diversity index value of Ocypodidae mangrove crabs obtained in the Lalombi Village mangrove area was 1.098. Based on the Shannon-Wiener index category, a value of 1 ≤ H' ≤ 3 indicates moderate diversity; therefore, the value of 1.098 reflects a moderate level of diversity. This moderate diversity indicates that the mangrove ecosystem in the study area is still capable of supporting several Ocypodidae species, although it may have experienced ecological pressures such as human activities or changes in habitat quality.

Abstract

This study aims to determine the density of macrozoobenthos in Toaya Village River Waters. This study uses a Quantitative Descriptive method with purposive sampling location determination consisting of 3 observation stations and sampling using the line Transect technique with a surber net sampling tool. Data analysis is done by calculating the density of samples that have been obtained in the field using the density formula. The results showed that (1) 5 types of macrozoobenthos were identified in the waters of Toaya Village River with the highest density at Station I (9.17 ind/m²) and the lowest at Station III (6.25 ind/m²). (2) These density differences reflect variations in environmental conditions, such as bottom substrate, water currents, pollution levels, and availability of organic matter. (3) Environmental conditions at station 1 are relatively more favorable for benthic organisms, while stations II and III reflect environmental pressures such as pollution or changes in habitat quality. Thus, macrozoobenthos acts as an effective bioindicator to assess water quality, so these results reflect the health level of the river ecosystem.

Abstract

This study aimed to identify bivalve species with high microplastic content and the types of microplastics present in those bivalves within the mangrove ecosystem of Desa Tanah Mea, Donggala Regency.  A quantitative descriptive method was used. Sampling locations were determined using purposive sampling, divided into two stations: Station I, a mangrove ecosystem adjacent to a residential area, and Station II, a mangrove ecosystem near the coastline. Bivalve samples were collected using the hand collection method, with 10 individuals per species.  Subsequently, bivalve tissues were processed, and microplastic content was analyzed. Data analysis involved counting the number and types of microplastics from the field samples using an abundance formula. Results showed that Polymesoda erosa, found at Station I, contained 22.2 microplastic particles per individual, comprising 104 fragments, 22 films, 92 fibers, and 4 foams.  Anadara granosa, found at Station II, contained significantly fewer microplastics, with 2.5 particles per individual, consisting of 12 fragments, 5 films, and 8 fibers. Polymesoda erosa was the bivalve species with the highest microplastic content, with fragments, films, fibers, and foams identified.  Therefore, bivalves can serve as bioindicators for assessing microplastic pollution levels in the mangrove ecosystem of Desa Tanah Mea, Donggala Regency.

Abstract

Waste is the result of human activities or natural processes. One of the largest sources of waste in urban areas is market waste which can cause public health problems and city aesthetics. The generation of market waste is quite large so that good management is needed so that market waste does not cause problems for city residents. The research method used is descriptive with an observational approach. Sampling was done by stratified random sampling, with a sample size of 230 traders. Data collection was carried out using an observation sheet in the form of a checklist. The results showed that out of 230 traders, 5.2% of traders had containers that met the requirements and 94.8% of traders were in the category of not meeting the requirements. Meanwhile, for storage, 18.7% met the requirements and 81.3% did not meet the requirements. For collection, 31.3% met the requirements and 68.7% did not meet the requirements, while for transportation, 91.7% met the requirements and 8.3% did not meet the requirements. Therefore, traders should replace damaged containers and related agencies should optimize waste management at the Pinrang Central Market
