Perancangan Sistem Kontrol dan Monitoring Kualitas Air dan Suhu Air pada Kolam Budidaya Ikan

The quality and the temperature of pond water is an important parameter that need to get attention in fish cultivation. Every type of fish has their own characteristic towards water condition and pond temperature.  The monitoring of water quality in cultivation pond is done manually and it takes a lot of time. The purpose of this research is to design web-based control system device and monitoring the quality of the water of fish cultivation pond including salinity, temperature and the hardness in real time using special application. This device design consists of salinity sensor, hardness sensor, and temperature sensor. Temperature can be controlled and monitored automatically on the application via computer/laptop. The result of this research is temperature drop by 0,1 oC on a 10 liters pond that takes 18 seconds, and to decrease the temperature of 1 oC takes 180 seconds (3 minutes). To raise the temperature of 0,1 oC takes 264 seconds or 4,4 minutes, and to raise the temperature of  1 oC takes 2640 seconds or 44 minutes. The percentage of error for sensor reading is ranged 2,4% - 3,9%

Observation cameras have been widely applied in various sectors of human life. Cameras are widely used for offices, schools, hospitals, and other public services. They are functioned as security, vehicle traffic monitor, and observation of a certain area. The use of the cameras as an observation is not only used on land but can also be used at sea and air. Areas which are dominated by oceans need to apply the right and effective surveillance cameras. Through this study, the cameras are designed for underwater observation. The cameras used are IP cameras which enable to be operated for surveillance systems up to dozens of meters below sea level. Underwater observation cameras also use an independent power supply through solar panels. Data delivery from cameras which are on the bottom of sea to users who are on land using a Wireless system in the form of a router located on sea surface. With addition of other supporting devices i.e. camera housing, and a computer/ a laptop, this research produces effective and efficient observation cameras. The purpose of this research is to design a camera system which can monitor images/videos under the sea remotely wirelessly by using computer/smart phone

One of the factors that caused the ship accident was extreme weather conditions. The absence of a device that can provide real time weather information for port systems and the departure of inter-island vessel ships that make the voyage less secure. The purpose of this study is to provide information related to weather conditions such as current direction, current velocity, wind direction, wind speed and wave height to the ship's captain and passenger ship. The toolkit consists of current velocity meter, wind speed gauge, current direction detection, wind direction detection and wave height meter. This inter-island information system device uses hall effect sensor and ultrasonic sensor. The sensor readings will be processed using Arduino Uno which is integrated with GSM Shield and then sent to the internet. Data residing on the internet will be monitored using Raspberry PI

Perancangan Perangkat Pengering Ikan Otomatis Skala Mini

Water content is the water content contained in the material and expressed in units of percent. Water content can affect the texture of fish and cause the development of bacteria in fish. In general, people only know the process of drying fish by looking at the texture of the fish while the water content found in fish is in accordance with the Indonesian National Standard (SNI), which is 40%. The purpose of drying fish is by controlling the water content so that the fish can be dried in accordance with the Indonesian National Standard (SNI). The control system contained in this device uses a DS18B20 temperature sensor, loadcell sensor, relay, heating element, and cooling fan. The working principle of this device uses a heating element to reduce the water content or load on the fish and the cooling fan to remove the hot temperature from the cabinet which is controlled by a relay to regulate the temperature. The heater will be active when the temperature is less than 60°C and the cooling fan is not active, when the temperature is more than 60°C. The device will automatically stop the heater when the load value is smaller or equal to the value of the set point. Reduction of water content up to 40% according to the Indonesian National Standard (SNI) with a 250g fish load takes 1 hour 43 minutes, a 500g fish load for 3 hours 17 minutes, and a 1000kg fish load for 6 hours 25 minutes. Keywords— Arduino Mega 2560, DS18B20, loadcell, keypad

Rancang Bangun Sistem Kontrol PH Air pada Palka Ikan Muatan Hidup Menggunakan Mikrokontroler dan LabVIEW

The live fish storege currently is not able to control the pH parameters of the water according to the fish's living environment. pH needs to be considered so that fish can survive. The purpose of this research is to design a system that can control the pH of water in fish hatch using a microcontroller and LabVIEW. The test is carried out on the hatch with dimensions of 90 cm x 65 cm x 50 cm. Monitoring changes in pH values in real time is done through LCD and LabVIEW. This device is equipped with an LED indicator that can indicate the condition of the relay outside of the LaBVIEW software. The difference in sensor readings designed with a standard measuring instrument is only around 0.05. The appearance process of the sensor reading value on the LCD and LabVIEW runs well with a response time reading of about 0.5 seconds and with a response time in controlling the relay about 0.3 seconds. Fish can survive using a control system designed during the testing process within 2x24 hours. The reading value from the sensor will be stored in real time as long as the LabVIEW software runs
