“…Peningkatan areal KJA di perairan Danau Laut Tawar berpotensi menimbulkan dampak buruk terhadap kualitas perairan danau tersebut. Penurunan kualitas perairan oleh aktivitas KJA disebabkan oleh beban limbah sisa kegiatan KJA [3,4,5]. Limbah aktivitas kegiatan KJA berupa sisa pakan yang tidak dikonsumsi dan sisa hasil metabolisme ikan [6,7] berupa feses dan urine.…”

“…Limbah aktivitas kegiatan KJA berupa sisa pakan yang tidak dikonsumsi dan sisa hasil metabolisme ikan [6,7] berupa feses dan urine. Sisa pakan dari KJA mengandung nitrogen (N) dan fosfor (P) merupakan faktor utama polusi budidaya perairan [3,8], begitu juga dengan feses dan urin merupakan sumber N dan P dari KJA [5].…”

“…Keberadaan senyawa N dan P ini secara berlebihan di perairan danau mendorong tumbuhnya fitoplankton secara berlebihan [5], sehingga menimbulkan eutrofikasi [9] di perairan danau. Eutrofikasi merupakan proses pengayaan nutrien oleh peningkatan unsur hara yang melampaui batas di ekosistem air [10,11] dan proses penumpukan nutrien, organik, dan sedimen yang mendorong penuaan alami danau [12].…”

“…Di sisi lain kelebihan fosfor dalam pakan pada sistem KJA akan dikeluarkan ke media budidaya [6,7], dimana akan menyebabkan penurunan kualitas air media budidaya [3,4,5]. Jumlah kelebihan fosfor pada sistem KJA Danau Laut Tawar dapat diketahui berdasarkan selisih jumlah fosfor yang diberikan yang terkandung dalam pakan dan jumlah fosfor yang tertinggal di tubuh ikan.…”

Floating net cage activities can cause water quality to decrease. The feed remains and the metabolism of the fish from these activities produces nitrogen and phosphorus . The objective of this study is to obtain the calculation model and the amount of phosphorus released into the waters of Laut Tawar Lake as a result of floating cage activities. The resulting formula was Pw = (F x [P]p) – ((It – Io) x [P]i), where their variables were given feed (F), phosphorus concentration of feed ([P]p), the final weight of fish (It), the initial weight of fish (Io), and phosphorus concentration in fishes ([P]i). It can be used to predict the increase in phosphorus waste based on the increase in floating net cage area. The weight of tilapia increases exponentially with the day of cultivation in the equation Y = 12.70e0.02x and the goldfish followed the formula Y = 2.28e0.03x. Phosphorus in tilapia varies from 1.58% to 2.23% with an average of 1.97%. Goldfish contain 1.19 - 2.02% phosphorus, with an average of 1.52%. Goldfish growth was not optimal due to inadequate feeding, so without excessive feeding and did not generate phosphorus waste. The cultivation of tilapia releases 0.09 Kg P/m2 of phosphorus waste from floating cages .

“…Management of Aquaculture can be carried out for sustainable aquaculture development, among others, by reducing nutrient inputs derived from FNC activities and reducing the number of FNC. It can also be done by implementing FNC with a water management system using recirculation and plantation (SMART FNC), an ecological friendly FNC with recirculating water, and where the waste is collected in the certain tank and used as a liquid fertilizer for aquaponics [25]. Besides, law enforcement and licensing are needed to be applied.…”

Juanda reservoir is one of the reservoirs located in Purwakarta Regency, West Java Province, Indonesia, whose primary function is hydropower, water resources for irrigation, industrial and drinking water, and secondary function for fisheries and tourism activities. Currently, an increase in activities around the existing reservoir has affected its water quality. In order to determine the water quality and trophic level status of the Juanda reservoir, research has been conducted within five stations during the period of August-December 2020. The water quality status includes physical, chemical, and biological parameters that compared with Store standards on Class II and III. Meanwhile, the trophic status was determined by Trophic Level Index (TLI) based on the parameters of transparency, chlorophyll-a, total nitrogen, and total phosphorus. The results show that the water quality status of Juanda reservoir has been contaminated Class III and heavily polluted Class II. The parameters that exceed include ammonia, nitrate, and BOD5. The Juanda reservoir's tropic status was in the eutrophic category, with TLI values ranging from 4.6 to 5.2.

Reservoirs and lakes are widely used for fisheries, both capture fisheries and aquaculture. Aquaculture fisheries that develop in reservoirs or lakes include floating net cages culture (FCC) and pen culture. Besides impacting the economy and employment opportunities, aquaculture activities through FCC can decrease water quality from uneaten feed and fish metabolism residue. For this reason, an environmentally friendly FCC is needed to reduce aquaculture waste. This paper reviews the development of ecologically friendly FCC research in Indonesia. Several studies on environmentally friendly FCC include double net FCC, bio-cages, carpel FCC, windowed, and triple layer FCC. Double net FCC still allows the remaining uneaten feed and feces to settle. Bio-cage research is in the innovation model stage and has no prototype or laboratory tests. Windowed FCC, made with a closed system and a few gaps for circulation, can accommodate aquaculture waste and not spread into the waters, but fish grow slower than other FCC. The loop bio-phytoremediation of FCC or Smart FCC has three layers that can accommodate waste, and the waste will be used for plants that function as filters and phytoremediators of waste. Smart FCC is an aquaponic system modified to be applied in reservoirs/lakes.
