Abstract

Salah satu komoditas perikanan Indonesia yang sangat potensial untuk dikembangkan adalah lobster (Panulirus spp.). Diperlukan sistem pengendalian pada pengondisian kolam lobster terutama kadar salinitas. Sistem pengendalian salinitas ini merupakan rancangan sistem yang digunakan untuk mengendalikan kadar salinitas air pada pengondisian kolam lobster. Hal ini berfungsi untuk menjaga kadar salinitas pada set point 27 ppt. Sistem pengendalian salinitas air ini menggunakan mode kontrol on/off dengan menggunakan komponen sensor salinitas, raspberrypi 3 B+, LCD display 16x2, serta solenoid valve dan pompa sebagai aktuatornya. Cara kerja sistem pengendalian salinitas air diawali dengan sensor yang membaca nilai kadar salinitas pada kolam lobster. Hasil pembacaan tersebut dikirimkan kepada raspberry pi 3 B+, kemudian data diolah yang selanjutnya ditampilkan pada LCD 16x4 dan website. Berdasarkan hasil pengujian penlis, didapatkan rata-rata error pembacaan alat sebesar 0,0005 %. Berdasarkan hasil penelitian tugas akhir ini didapatkan karakteristik dinamik respon salinitas pada respon pertama didapatkan rise time (Tr) selama 1 menit dan maximum overshoot (Mp) 1,17 %, seperti yang terlihat pada Gambar 4.8. Adapun settling time (Ts) selama 1 menit, delay time (Td) 0,5 menit, dan error steady state (Ess) 0,74 %. Pada respon kedua didapatkan rise time (Tr) sebesar 25 menit, maximum overshoot (Mp) 0,99 %, settling time (Ts) selama 1 menit, delay time (Td) 12,5 menit, dan error steady state (Ess) 0,03 %. Pada respon ketiga didapatkan rise time (Tr) selama 43 menit, maximum overshoot (Mp) 1,00 %, settling time (Ts) sebesar 57 menit, delay time (Td) 21,5 menit, dan error steady state (Ess) 0,12%. Kemudian pada respon keempat didapatkan rise time (Tr) sebesar 67 menit, maximum overshoot (Mp) 1,01 %, settling time (Ts) pada menit ke-82, delay time (Td) 33,5 menit, dan error steady state (Ess) 0,03 %. Selain itu, didapatkan nilai rata-rata pembacaan error di bawah 2% yaitu 0,0005%.

One of Indonesia's fisheries commodities that is very potential to be developed is lobster (Panulirus spp.). A control system is needed in the conditioning of lobster pools, especially salinity levels. This salinity control system is a system design that is used to control the water salinity level in the lobster pool conditioning. This serves to maintain salinity levels at a set point of 27 ppt. This water salinity control system uses the on / off control mode by using salinity sensor components, raspberrypi 3 B +, 16x2 LCD display, and solenoid valve and pump as actuators. The workings of the water salinity control system begin with a sensor that reads the value of salinity in the lobster pool. The reading results are sent to raspberry pi 3 B +, then the data is processed which is then displayed on the 16x4 LCD and website. Based on the results of testing the devil, obtained an average error of reading the tool by 0,0005%. Based on the results of this final project research, the dynamic characteristics of the salinity response in the first response obtained rise time (Tr) for 1 minute and maximum overshoot (Mp) 1.17%, as shown in Figure 4.8. The settling time (Ts) for 1 minute, delay time (Td) 0.5 minutes, and steady state error (Ess) 0.74%. In the second response, the rise time (Tr) is 25 minutes, maximum overshoot (Mp) is 0.99%, settling time (Ts) for 1 minute, delay time (Td) is 12.5 minutes, and error steady state (Ess) is 0 , 03%. In the third response, the rise time (Tr) is 43 minutes, maximum overshoot (Mp) is 1.00%, settling time (Ts) is 57 minutes, delay time (Td) is 21.5 minutes, and error steady state (Ess) is 0 12%. Then in the fourth response we get a rise time (Tr) of 67 minutes, maximum overshoot (Mp) of 1.01%, settling time (Ts) in the 82nd minute, delay time (Td) 33.5 minutes, and steady state error ( Ess) 0.03%. In addition, the average value of reading errors below 2% is 0.0005%.
