Abstract

Pemanfaatan danau untuk budidaya perikanan merupakan salah satu pendukung pertumbuhan ekonomi, akan tetapi dapat berdampak buruk pada kualitas air danau. Salah satu parameter kualitas air danau yang berpengaruh adalah konsentrasi Dissolved Oxygen (DO). Pencemaran pada perairan di danau didominasi dari sisa limbah pakan budidaya ikan dan limbah domestik. Mengakibatkan sisa pakan ikan yang tersisa dapat menurunkan kualitas air danau. Oksigen terlarut pada air dibutuhkan untuk respirasi dan metabolisme makhluk hidup di perairan. Selain itu digunakan untuk dekomposisi bahan organik dan anorganik. Jika limbah organik yang masuk pada perairan sangat banyak maka kandungan oksigen pada perairan tersebut akan semakin berkurang. Pada perairan danau memiliki baku mutu kandungan oksigen terlarut yang sudah diatur pada Peraturan Pemerintah No 22 Tahun 2021 yaitu 4 mg/l. Oleh karena itu diupayakan konsentrasi oksigen terlarut pada perairan danau memenuhi baku mutu tersebut. Kontrol dan monitoring oksigen pada umumnya dilakukan dengan menggunakan sensor network wireless. Data kandungan oksigen pada danau di kirim dikumpulkan di personal computer untuk dianalisis dan dibandingkan dengan nilai standar parameter air. Dalam penelitian ini dilakukan perancangan penggabungan teknologi monitoring kadar oksigen terlarut dan aerasi injeksi gelembung oksigen otomatis dengan mikrokontroler Arduino Uno secara real time in-stream. Pengujian alat ini menggunakan 3 sampel air yaitu air danau suhu 29oC, air bersih suhu 25oC, air bersih suhu 13oC. Perbedaan suhu ini digunakan untuk menguji apakah alat yang sudah dirancang dapat bekerja dengan baik pada perbedaan suhu tersebut. Data yang didapat berupa pembacaan sensor DO dan cara kerja relay dalam deteksi kadar DO setiap 1 detik atau 5 menit. Data dari hasil penelitian akan diuji analisis berdasarkan laju reaerasi dan deoksigenasi untuk mengukur peningkatan dan penurunan kadar oksigen terlarut (DO drop). Rata rata laju reaerasi pada air danau suhu 29oC didapatkan 1 mg/l menit, pada air bersih suhu 25oC adalah 0,8 mg/l menit dan suhu 13oC yaitu 0,7 mg/l menit. Pada percobaan selama seratus menit didapatkan laju reaerasi 0,59 mg/l menit dan laju deoksigenasi berdasarkan data percobaan jika kadar DO semakin meningkat maka nilai laju penurunan oksigen semakin kecil. Detail pengaplikasian teknologi yang sudah dirancang pada keramba jaring apung budidaya ikan di danau secara 3D aplikasi SketchUp.

The use of lakes for aquaculture is one of the supporters of economic growth, but it can have a negative impact on the quality of lake water. One of the influential lake water quality parameters is the concentration of Dissolved Oxygen (DO). Pollution in the waters in the lake is dominated by the remaining fish farming feed waste and domestic waste. As a result, the remaining fish feed can reduce the quality of lake water. Dissolved oxygen in water is needed for respiration and metabolism of living things in waters. In addition, it is used for the decomposition of organic and inorganic matter. If organic waste enters the waters very much, the oxygen content in these waters will decrease. Lake waters have a quality standard for dissolved oxygen content which has been regulated in Government Regulation No. 22 of 2021, which is 4 mg/l. Therefore, the concentration of dissolved oxygen in lake waters is sought to meet these quality standards. Oxygen control and monitoring is generally done using wireless network sensors. Data on the oxygen content in the lake are sent collected on a personal computer to be analyzed and compared with standard values of water parameters.In this study, a design was carried out combining dissolved oxygen level monitoring technology and automatic oxygen bubble injection aeration with Arduino Uno microcontroller in real time in-stream. Testing this tool uses 3 water samples, namely lake water temperature 29oC, clean water temperature 25oC, clean water temperature 13oC. This temperature difference is used to test whether the tool that has been designed can work properly at the temperature difference. The data obtained is in the form of DO sensor readings and how relays work in detecting DO levels every 1 second or 5 minutes. Data from the results of the study will be tested for analysis based on reaeration and deoxygenation rates to measure the increase and decrease in dissolved oxygen levels (DO drop). The average reaeration rate in lake water temperature of 29oC is obtained 1 mg/l minute, in clean water the temperature of 25oC is 0,8 mg/l minute and the temperature of 13oC is 0,7 mg/l minute. In the experiment for one hundred minutes, the reaeration rate was obtained 0,59 mg/l minute and the deoxygenation rate based on experimental data, if the DO level increased, the value of the rate of oxygen decrease was smaller. Details of the application of technology that has been designed on floating net cages fish farming in lakes in 3D the SketchUp application.
