Abstract

The sea is one of the sources of wealth in Indonesia. Damage to and on the sea greatly impacts marine ecosystems and the livelihoods of people on the coast. Oil spills are the main source of marine pollution. Several ways of handling oil spills are carried out utilizing mechanical removal, using sorbents, and using dispersants. This countermeasure is carried out in offshore sea areas so that large ships and human resources are needed are many and qualified technologies needed that can help handle oil spills can be done remotely by designing a wireless system that can control an unmanned waste oil cleaning robot. This study aims to get the results of Bluetooth module as a wireless control system for waste oil cleaning robots and to implement Bluetooth module for this robot control system. The design of this robot control system utilizes the HC06 Bluetooth module as a connection to connect to the smartphone and uses the Arduino Uno R3 block to enter algorithm programming to be able to drive a waste oil cleaning robot. Bluetooth module testing is carried out with treatment with and without obstacles with a range of 1-15 m. Tests were also carried out to move the robot to go forward, backward, and turn right, and left. The control of the waste oil cleaning robot can be properly connected at all ranges with unhindered treatment at all ranges. While the treatment with obstacles can only be connected up to a distance of 9 m. The performance of the cleaning robot to move forward, backward, turning right, and left with a 100% success rate. Based on the test data, it can be concluded that the Bluetooth module HC06 and Arduino Uno R3 can be applied to control robots cleaning waste oil.

Abstract

Cilembu sweet potato is an agricultural product that is in great demand by the community. One of the processes carried out after harvesting is determining the weight of the cassava. This weight measurement is done to classify Cilembu sweet potato according to weight so that the selling price of the product can also be adjusted. Sorting by weight can be done using image processing methods. This method is more accurate than other sorting methods. The purpose of this study was to separate Cilembu sweet potato products based on weight using image processing methods. This study uses 2-dimensional image processing to determine the weight of Cilembu sweet potato. The results of this Cilembu sweet potato sorting machine research obtained the value of the linear regression equation x = (y – 10476) / 153.05 and the value of R-squared (R²) = 0.759 . The results of heavy testing have an average error of 7.62%. The standard deviation of the presentation error is 5.61.

Abstract

Salt is a solid and crystalline substance produced from sea water. The salt that we know has a collection of compounds whose main part is Sodium Chloride (NaCl) as well as several impurities such as Calcium Sulfate (CaSO4), Magnesium Sulfate (MgSO4), Magnesium Chloride (MgCl2) and others. The washing process needs to be carried out to remove impurities so that NaCl levels on salt increase. The washing process with stirring in several rotation variations was used to increase the NaCl content on salt. This research aimed to determine the effect of the rotation speed of the stirrer blade in the washing process in increasing the NaCl content on salt. This research used variations in rotation speed of 40 rpm, 80 rpm, and 120 rpm and compared the increasing trend with washing times of 15 minutes and 20 minutes. The experiment showed the best rotation speed in the washing process to obtain the greatest salt content is a rotation speed of 80 rpm. Experiment with variations in rotation speed with washing times of 15 minutes and 20 minutes showed that increasing the rotation speed did not have a significant effect on increasing NaCl content of salt in the washing process.
