Abstract

Scheduling is one of the most difficult computing problems to solve. Problems in scheduling also occur in SMA Negeri 3 Surakarta which has implemented the 2013 curriculum with the system of university credit unit which for the implementation consists of two courses, namely 4 semester program and 6 semester program. Genetic algorithm is a search method that can be used to obtain optimal solution. Representation of chromosome in the research is divided into two segments, those ares chromosome length 748 for 6 semester program and 86 4 semester program. The optimal solution is obtained from the test that conducted 10 times and obtained the optimal parameter value of population size 600 individuals, the number of generations 1000 times, the value of cr 0.5 and the value mr 0.5. The results of the optimal solution in the form of course schedules for the 6 semester program and 4 semester program obtained from the highest fitness value of 0.16208. The result of the solution obtained from the highest fitness value is not optimal because there are still violations on the constraint in the scheduling of the courses in SMA Negeri 3 Surakarta.

Abstract

A good distribution is one of the company's strategy to increase the productivity of the company. Distribution strategy is indispensable in bottled drinking water, because bottled water business has increased every year. Distributor of bottled water has a variety of types and brands of goods with different packaging forms. The number of shipping destinations poses many problems in the distribution process, because it takes more time to arrive at different address and distances. This research has a goal to create a system that can help the process of distribution of goods with number of sales more than one, the problem is called Multiple Traveling Salesman Problem (M-TSP). One method to solve M-TSP problem is to use genetic algorithm, so it can determine the route with the shortest distance that will be visited by every sales. The genetic algorithm process uses permutation representations with chromosome length according to many customer orders and the number of orders on each sales, each gene is a number representing the customer number and the number of orders that each salesperson should visit. The test results show that the route sequence generated from the application of the genetic algorithm is better than that applied to the distributor with a total distance of 89.3 km and the fitness difference is 10.656578. The optimal parameters were obtained by generating population size 180, 400 generation and crossover rate 0.6 and mutation rate 0.4.

Abstract

At this time the chain lubrication which is conducted by operator on conveyor machine spent a lot of time because of the number of conveyor machine. The operator must lubricate a lot of conveyor chain so that the working hours become inefficient. To solve the problem then made an automatic lubrication system. The purpose of this research so that operators can manage the lubrication time on conveyor chain and then the operator can do their job. This automatic lubrication system works based on current level obtained by using ACS712 current sensor which is then calculated using linear regression method in arduino UNO to get the prediction value of lubrication duration. This value is used to activate wind solenoid relay, oil pump relay and oil solenoid relay. After the prediction of lubrication time has been fulfilled by all relays, the system re-measure the current for further lubrication. Proximity sensor is useful when the system is active, the oil pump relay is also active to deliver oil from the oil pump to the oil solenoid. This research uses linear regression method. The solution of this method is to use the current parameter as the independent variable (X) and the time of manual lubrication as the dependent variable (Y) so that the predicted value of the dependent variable (Ŷ) can be calculated as the duration of the automatic lubrication time. By using this method when the current reached the value of 3.88 A obtained the prediction value of the duration of automatic lubrication for 210 seconds. With 2.21% value of error between manual lubrication and automatic lubrication, the predicted value is not much different from manual lubrication time. The the difference predicted value is not too much between manual lubrication time and automatic lubrication system.
