Abstract

Salah satu aspek yang diperhatikan dalam budidaya udang yaitu pemeliharaan kualitas air. Manajemen kualitas air merupakan salah satu cara yang dapat dilakukan oleh para pembudidaya untuk meningkatkan produksi udang vannamei. Kegiatan yang dapat dilakukan dalam manajemen kualitas air pemeliharaan adalah monitoring faktor fisika, kimia, biologi dan pengelolaan berupa pemberian perlakukan jika terjadi penyimpangan nilai optimal parameter. pH dalam suatu perairan dapat dijadikan indikator dari adanya keseimbangan unsur-unsur kimia ketersediaan unsur-unsur kimia dan unsur-unsur hara yang sangat bermanfaat bagi kehidupan vegetasi akuatik.
Sistem kontrol pH dan salinitas air dengan memanfaatkan metode logika Fuzzy digunakan untuk menjaga nilai pH dan salinitas pada kisaran angka optimal. Proses perancangan dibuat dalam bentuk prototype. Tempat yang digunakan berupa box container dengan volume 90 liter. Beberapa komponen yang digunakan yaitu sensor pH, sensor salinitas, empat buah pompa, Arduino Uno, relay, dan larutan penstabil pH dan salinitas.
Pengujian dilakukan menggunakan prototype tambak melalui box container. Pengujian dilakukan dengan membandingkan hasil pengukuran sensor dengan alat ukur. Didapatkan hasil berupa presentase kesalahan untuk sensor Ph awal sebesar sebesar 9.55%, sedangkan untuk salinitas awal yaitu 22.08%. Sedangkan untuk presentase untuk pengukuran Ph akhir sebesar 10.54% dan salinitas akhir sebesar 12.44%.

One aspect that is considered in shrimp farming is the maintenance of water quality. Water quality management is one way that farmers can do to increase vannamei shrimp production. Activities that can be carried out in maintenance water quality management are monitoring physical, chemical, biological factors and management in the form of giving treatment if there is a deviation from the optimal parameter value. The pH in a waters can be used as an indicator of the balance of chemical elements, the availability of chemical elements and nutrients that are very beneficial for the life of aquatic vegetation.
The pH and salinity control system using fuzzy logic method is used to maintain the pH and salinity values in the optimal range. The design process is made in the form of a prototype. The place used is a box container with a volume of 90 liters. Some of the components used are pH sensors, salinity sensors, four pumps, Arduino Uno, relays, and pH and salinity stabilizing solutions.
The test was carried out using a pond prototype through a box container. Testing is done by comparing the results of sensor measurements with measuring instruments. The results obtained in the form of an error presentation for the pH sensor of 11.82%, while for the salinity it is 20.3%. Meanwhile, the percentage for the final pH measurement is 10.54% and the final salinity is 12.44%.
