Number of fish seed can be measured by means of conventional observation using eye senses. But when the fish seed measured pretty much it will take a long time (not efficient) and cause incorrect measurement results (inaccurate). The accuracy of calculation of fingerlings is crucial trust between seller and buyer.During this time a sensor is used to detect the amount of fish seed is passed through a transparent hose using a light sensor (Light Dependent Resistor) and photodiode sensors as infra red light receiver. The level of accuracy of the sensor lies in the intensity of the light beam is received so that the sensor will be impaired if airya murky and there are air bubbles pass through the sensor so that the fish count error occurs.This research will be conducted design counters the number of fingerlings using infra red phototransistor sensor with a frequency of 20KHz to fish and then processed using the logic matrix. Results matrix logic into the data input to be processed by a microcontroller as the basis of results of calculation of the amount of fish.Development model studies using models of R & D (research and development) that produce a product in the form of the final product. Experiments were carried out using the type and length of catfish fingerlings with a length of 3 cm to 5 cm. Fish seed count tool has been tested to catfish farmers in the village Siwarak Ungaran City.The trial results calculators fish seeds have difference of 3% of the calculated results Manual or accuracy of calculation results have fish reaches 97%, then a counter of fish seed is acceptable to be used by catfish farmers.

The increase in motorized vehicles in urban areas is followed by an increase in cases of motorcycle theft due to the lack of public awareness about the motorcycle security system. The intensity of motorcycle theft with its disclosure is still far in comparison. Crime will also increase, such as cases of theft of motor vehicles, especially motorbikes. Cases of motorcycle theft still often occur, this happens because there is still a lack of security systems contained in motorized vehicles that only use ignition. the existence of an alternative safety system is needed because the average key of a conventional motorcycle is easily penetrated by thieves.

In the highlands it is indeed cold and there is little possibility of plantation fires. However, fires can occur as a result of human activity both intentional and unintentional. The location of the plantation land that is relatively far from the residential population makes fires sometimes known too late. Therefore, it is necessary to create a tool to monitor the temperature and concentration of guava plantation smoke from a distance every day so that if the temperature or the density of smoke reaches a certain number that indicates the occurrence of fire then the tool will immediately send a notification via SMS to the plantation owner. In addition, the tool will immediately pour water from the reservoir or water reservoir into the guava plantation. In the water reservoir there is a tool to detect the volume of water. The device to be created uses the LM35 temperature sensor, MQ-2 smoke sensor, HC-SR04 Ultrasonic sensor, Relay, Arduino Uno R3 microcontroller and GPRS Shield along with the GSMSIM Card.
