The decrease in water quality is caused by the presence of pollutants in the form of organic and inorganic components. Inorganic components, including heavy metals, one of which is iron (Fe). Adsorption is one of the technologies that can be used to absorb heavy metals where the adsorbent used in this study is a shell of a shell (Telescopium telescopium) to absorb iron (Fe2+). This research aims to utilize the waste of the mussel shells (Telescopium telescopium) as an adsorbent for heavy metal iron (Fe2+). The study was divided into three stages, namely the adsorbent surface characterization, determining the optimum time and determining the adsorption capacity. All stages of the study were carried out on adsorbents that were not activated and NaOH. The results showed the largest pore size after activation was 1,398 µm, while the adsorbent before activation, the largest pore size was 844.8 nm. The surface acidity of the adsorbent before activation is 5.28 mmol / g and after activation has a value of 6.74 mmol / g. The optimum time of absorption of ferrous metal ions (Fe2+) before and after activation is 60 and 30 minutes. The adsorption capacity of the adsorbents before and after activation was 11,07899 mg / g and 459,3038 mg / g, respectively. It was concluded that the shell of a temberungun shell (Telescopium telescopium) can be used as an adsorbent for heavy metal ions (Fe2+)

Betta fish is one of the excellent ornamental fish because it has high economic value. Betta fish that have economic value are male betta fish because it has a beautiful shape. To increase male fish production, steps can be done by masculinization. This study aims to determine the effect of celery extract on the percentage of male betta fish by masculinization. This study uses a completely randomized design (CRD) with 6 treatments and 3 replications. The treatment in this study was 7-day-old betta fish larvae soaked in celery extract media with different concentrations for 8 hours. The treatment is the addition of celery extract as much as 5 mg / L (P1), 10 mg / L (P2), 20 mg / L (P3), 40 mg / L (P4), 80 mg / L (P5) and without the addition of celery extract as a control (P0). Based on phytochemical testing, celery ethanol extract contains steroids, flavonoids, tannins, and phenols. The results showed that the addition of celery extract with different concentrations had a significant effect on the percentage of male betta fish, but there was no significant effect on survival rates.

Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher at Gersen station than Nusi station. Community similarity index by species is low between the two stations, which indicates that the species of gastropods at both stations is quite different. The influence of human activity and higher utilizatin of gastropods in Nusi has lowered the density of gastropods in seagrass habitat, so it needs awareness efforts on the importance of gastropods and the seagrass habitat for coastal ecosystem.
