This research aims to determine the ecosystems connectivity by observing the distribution of inter-island mangrove propagules in the territorial waters of Biawak Island. The data used are wind, tidal, and bathymetry of 2018. They are modeled according to the propagules’ weight and the particle trajectory module. The results showed that the entire propagules (Rhizopora sp, Sonneratia sp, and Brugueira sp) dominantly moved to the west and southeast. They are carried by the currents that are influenced by the west and east monsoon. The propagules of Rhizopora sp moves from east to southeast, Sonneratia sp moves from east to south, and propagules Brugueira sp moves from west to north. In addition to oceanographic factors, other parameters that can influence the pattern of propagules movement is the propagule’s mass; the lighter it is, the easier it is to be carried away.

Aims: The purpose of this study was to determine aquatic plants (Lemna perpusilla, Landoltila punctata and Azolla pinnata) that have the most effective ability as phytoremediation agents for catfish cultivation wastewater.

Study Design: This research was conducted by an experimental method, with a Completely Randomized Design (CRD) consisting of three treatments and four replications.

Place and Duration of Study: This research is located at the Wet Laboratory (Ciparanje) of the Faculty of Fisheries and Marine Sciences, Padjadjaran University. Water quality testing is carried out at the Water Resources Laboratory of the Faculty of Fisheries and Marine Sciences. Research was carried out on 20 July-24 September 2019.

Methodology: The test wastewater was collected from catfish pond culture and put into twelve aquarium with a volume of 8 litre. Physical and chemical parameters observed include BOD5, dissolved oxygen, CO2 acidity, temperature, nitrate, and phosphate.

Results: Lemna perpusilla, Landoltia punctata and Azolla pinnata were able to improve the quality of catfish culture wastewater such as increasing the concentration of dissolved oxygen (DO) and pH, and reducingBOD5, CO2, nitrate and phosphate. Lemna perpusilla was able to reduce the concentration of BOD5, CO2,carbondioxide, nitrate and phosphate from catfish cultivation wastewater by75%; 77.7%; 23.4%; 44.2%, respectively, during the phytoremediation process, and Landoltia punctata was able to reduce the concentrations same parameters by 52%; 68.3%; 17.8%; 18.3% and Azolla pinnata by 41%; 84%; 15.3% and 28.4%.

Conclusion: Lemnaper pusillamay improve the quality of catfish culture wastewater better than Landoltia punctata and Azolla pinnata. Lemna perpusilla can be recommended as phytoremediation agents catfish cultivation wastewater to remediate organic matter before being discharged directly into water bodies.

Jatigede Reservoir is a reservoir located in Sumedang West Java which is built for irrigation, raw water, power generation, tourism, and capture fisheries. This research aims to determine the value of primary productivity as one of the indicators of the water body feasibility of the Jatigede reservoir to capture fisheries activities. The study was conducted in August – September 2019. Sampling is carried out at 4 stations on the surface, half the depth of compensation, and the depth of compensation. Estimation of primary productivity using chlorophyll-a concentration measurement method. The results of measurement of water quality parameters in the Jatigede reservoir include transparency range of 19,5 cm – 116,5 cm, temperature with a spread of 26,58 – 27,48oC, pH with a range of 7,69 – 8,40, carbon dioxide with a range of 4,190 mg/L – 9,219 mg/L, current ranges from 0.136 m/s – 0,216 m/s, BOD5 with a range of 11,027 dissolved oxygen ranges from 6,4 mg/L – 7,1 mg/L, ammonia ranges from 0,006 mg/L – 0,039 mg/L, nitrates ranged from 0,168 mg/L – 0,216 mg/L, and phosphate range 0,139 mg/L – 0,185 mg/L. Results from the measurement of chlorophyll-a ranged from 0,035 mg/L – 0,062 mg/L. This results in showing the Jatigede reservoir of oligotrophic water because the primary productivity in the waters of the Jatigede Reservoir is relatively low if calculated based on the concentration of chlorophyll-a.

Nilem fish (Osteochilus hasselti) is a type of freshwater fish that is widely farmed in West Java. Another application of nilem fish is made into fish protein concentrate (FPC) flour. The addition of fish protein concentrate flour to the mochi cake can affect the proximate characteristics. This study aims to determine the proximate characteristics of mochi cake added by nilem fish protein concentrate flour. This research was conducted from August 2019 - January 2020 at the Laboratory of Fisheries Product Processing, Faculty of Fisheries and Marine Sciences, and the Chemical Research and Services Laboratory, Basic Science Service Center (PPBS), Padjadjaran University. The method used in this research was experimental with two treatments, that were the addition of 0% and 4.5% nilem fish protein concentrates from white glutinous rice flour was used. The parameters observed were proximate characteristics including carbohydrate, water, protein, fat, and ash content. The results showed that mochi cake with the addition of 4.5% of nilem fish protein concentrate had proximate characteristics namely carbohydrate content 59.57%, water content 29.93%, protein content 8.71%, fat content 1.41%, and ash content 0.38%.
