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 isolate and characterize fungi from the rhizosphere of carrots grown in non-organic systems that potentially produce indole-3-acetic acid (IAA), and to evaluate their biostimulatory potential in supporting environmentally friendly agriculture. The methods employed included rhizospheric sample collection from non-organic carrot fields, fungal isolation and purification using PDA media, morphological identification, as well as qualitative screening and spectrophotometric quantification of IAA production using Salkowski reagent. The results revealed six fungal isolates capable of producing IAA, namely Rhizopus stolonifer, Rhizopus oryzae, Trichoderma longibrachiatum, Trichothecium roseum, Pythium aphanidermatum, and Pythium inflatum, with varying levels of IAA production. Among these, R. oryzae produced the highest IAA concentration at 46.8 ppm, followed by P. aphanidermatum (41.8 ppm), T. longibrachiatum (27.3 ppm), P. inflatum (24.5 ppm), R. stolonifer (18.4 ppm), and T. roseum (17.9 ppm). These findings suggest that rhizospheric fungi from the non-organic carrot rhizosphere hold promising potential as IAA-producing bioagents to support sustainable and environmentally friendly agricultural practices.

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

The purpose of this study is to test the  antioxidant activity of kepuh seed extract (Sterculia foetida) as well as its potential in neutrophil testing for mouse immunity (Mus musculus). This study was experimental by looking at the number or ratio of neutrophils in mice that had been given stress treatment in the form of wounds on the body of mice after being given kepuh seed extract. The antioxidant activity test is carried out using the DPPH method, while the neutrophil test can be carried out using the flow cytometry method. The results of the antioxidant activity test using the DPPH method (IC 50) showed a result of 18.0361 mg/mL. The regression results of levels (mg/mL) vs antioxidant activity (%) showed that the higher the level of kepuh seed extract, the higher the percentage of antioxidant ability available. Based on the results of the research, it can be concluded that; (1) The concentration of 18.0361 mg/mL in chickpeas (Sterculia foetida) can inhibit free radicals in the body, so it can be said that chickpeas (Sterculia foetida) have strong antioxidant activity; (2) The higher the content of kepuh seed extract, the higher the percentage of antioxidant ability.

Abstract

This study aims to examine the feeding habits and analyze the stomach contents of the fish caught in the waters of Talaga Jati Taruna. This study was conducted in an exploratory approach by obtaining fish samples from the fishers, followed by morphometric analysis and identification of natural food types in the digestive tract. The results showed that Nile tilapia (Oreochromis niloticus) had a positive allometric growth pattern with a regression coefficient (b) of 3.15 and a determination value of 0.99, indicating that body weight gain was faster than length gain. The relative gut length (RLG) analysis showed that both species are classified as herbivores, with RLG values greater than 3. Diet composition showed that phytoplankton dominated the stomach contents of both species, with the Cyanobacteriia dominating the Nile tilapia diet (IP% = 73.3%) and the Dinophyceae dominant in Mozambique tilapia (IP% = 70.56%). Abiotic parameters were still within optimal ranges to support aquatic life. These findings emphasize the importance of phytoplankton and zooplankton availability as natural food sources in supporting the growth and ecological balance of the Talaga Jati Taruna aquatic ecosystem.

Abstract

This study aims to determine the morphological and anatomical description of lichen thalus growing in urban areas. Sampling using exploration method (Cruise Method) and lichen thalus sampling technique is done by Purposive Sampling. Lichen thalus sample preparation was done by Embedding method. The results of this study indicate that (1) The life of lichen in urban friends is influenced by several factors including temperature, humidity and air pollutants that correlate with the LoS index value in Surakarta City. (2) Two species were found, Parmelia sp and Dirinaria sp that have different morphology and anatomy, which is caused by the characteristics of lichen substrate and air quality in the area. (3) Dirinaria sp species found in all study sites proved that the species is tolerant to environmental stress and is a taxon that characterizes urban areas. (4) The level of LoS index value in Surakarta City is also one of the factors that cause changes in the anatomical structure of the lichen thalus, namely the upper cortex layer. Thus, the higher the LoS index value in a road section, the thicker the size of the cortex thickness of the lichen thalus growing on the substrate in Surakarta City.
