Abstract

Excessive and periodic use of insecticides has a negative impact on aquatic areas and the biota in them. Pesticides that accumulate in the aquatic environment affect the life non target organisms such as fish. In addition, pesticides can cause damage to the gills, liver, intestines and spleen. This organ plays an important role in the immune system. Thus, an alternative is needed to overcome this problem, one of which is the addition of activated charcoal in the feed. The aims of study to determine the effect of the use of activated charcoal in feed on the histopathological description of the spleen of tilapia exposed to organophosphate pesticides. The study was conducted experimentally by applying 4 treatments and 2 replications as the treatments used included T1 (0% activated charcoal); T2 (1% activated charcoal); T3 (2% activated charcoal); T4 (3% activated charcoal). The test fish used were tilapia measuring 7 ± 0,4 cm long with a stocking density of 30 fish/container. Parameters observed were histopathological description of tilapia spleen at pre exposure, post exposure and after administration of activated charcoal. The results of observations of tissue damage were analyzed descriptively qualitatively and presented in the form of images. The results showed that the addition of 2% activated charcoal (T3) in the feed was able to reduce damage to the spleen due to exposure to organophosphate insecticides.

Abstract

Wairuhu River is disembogued on the sill of Poka-Galala, Ambon Bay. The estuary is affected by the coastal reclamation which led to the fester sedimentation. It triggers the problem of altering the shoreline and the dynamics of water movement, as well as the surrounding ecosystem. The modeling approach was applied to reconstruct the alterations around the estuary. The study aimed to estimate the changes on the shoreline, current patterns, and sediment transport patterns (suspended sediment), and to describe marine resources around the estuary of Wairuhu. MIKE 3 FM was utilized to reconstruct the pattern of flow and sediment transport changes, and coordinates plottings from satellite data were used to measure the coastline. The model was validated by using the data of tide and surface flow. The results showed the alteration pattern of the shoreline around the Wairuhu estuary occurred as a result of coastal reclamation. The flow validation (mooring and model) using RMSE was 0.38 which meant there was no difference between the model and mooring. By the model, the flow pattern that passed through the APG was following the tidal pattern. The changes in the tidal platform also occurred on the sediment transport pattern that formed the total distribution pattern of SSC (suspended sediment concentration). Several classes of macroflora and macrofauna were uncovered, such as Malacostraca, Echinoidea, Bivalvia, Asteroidea, Ophiuroidea, and Gastropoda.Keywords: Modeling; Poka-Galala sill; Sedimentation; Wairuhu River

Abstract

Segara Anakan Lagoon is a unique and distinctive area where most of the ecosystem is dominated by mangrove ecosystems. Some fauna make the ecosystem as a place for feeding ground, nursery ground and spawning ground for example macrozoobenthos. Its sessile nature makes the biota used as a bioindicator of an area. The Segara Anakan mangrove forest is currently under pressure due to the process of sedimentation and conversion of functions by residents. Therefore, this study aims to determine the interaction between the abundance of macrozoobenthos with environmental conditions. The research was carried out in July-September 2021 at the Segara Anakan Lagoon, Cilacap. The sampling method used is the Sample Survey Method with three stations determined purposively by describing different habitat conditions. Sampling was carried out on a monthly and the data obtained were analyzed by PCA. The results showed that the highest abundance of macrobenthos was found in the western part of the Segara Anakan mangrove forest. The value of macrozoobenthos abundance is influenced by TSS related to food availability. Furthermore, the quality of water and soil is still in accordance with the quality standards of marine life.Keywords: Environmental Characteristics; Macrozoobenthos; Mangrove; Segara Anakan
