Abstract

One of the Posyandu, namely Posyandu Permatasari, every month, a health check is carried out for toddlers and the elderly. This health monitoring is seen from several indicators, the recordes on the Kartu Menuju Sehat (KMS). After that, it will be recorded in the reports and the health ranking of toddlers and elderly will be made. In doing the ranking, currently Posyandu cadres are still doing the sorting by manually comparing toddlers and elderly people. So that it takes quite a long time, and sometimes there are writing errors. Therefore, researchers created a system to rank healthy toddlers and elderly people, which is expected to help increase the effectiveness and efficiency of Posyandu cadres in monitoring progress and making reports easier. This research will be made using the Analytical Hierarchy Process (AHP) method to find the weight of the criteria used and the Weighted Product (WP) to rank each alternative using the weight obtained in the AHP calculation. Based on the result of the tests that have been carried out, for toddler data in testing changes in the value of comparison matrix between criteria, for all matrix changes, the accuracy value was 100% with maximum lambda value of 2, CI value 0, and CR value 0. Meanwhile for the elderly data, in the testing changes in the value of comparison matrix between criteria, the highest accuracy value was 90% wih maximum lambda value of 8,361, CI value 0.05157, and CR value 0.03657.

Abstract

Modified K-Nearest Neighbor (MK-NN) has been widely used to classify various types of objects. In carrying out the classification, MK-NN calculates the distance k closest neighbors in the training data. The difference between K-Nearest Neighbor (K-NN) and M-KNN is found in the process of calculating the validity of all training data and weight voting. The MK-NN algorithm calculation stage is calculating the distance between training data, calculating the value of the training data validity, calculating the distance between the training data and test data, and calculating weight voting. The biggest weight voting results taken are the number of K used. From the weighted voting results, the class of the largest weight voting value is the disease class from the test data. Potato plant data (Solanum tuberosum L) were used as many as 115 training data and test data with 7 types of diseases and 23 disease symptoms. The accuracy of this system depends on the k value and the total training data used. Big value of K make small the accuracy because the validity value obtained is smaller. The more training data used, the higher the accuracy because the difference between Euclidian grades between classes is greater. The best system accuracy is obtained from the value of k = 4 and total training data of 45 is 97.142857%.

Abstract

The Islamic Learning Application with the Android-based Quiz method is an Islamic religious learning application using the quiz method. There are multiple-choice quizzes, true-false quizzes, materials, work statistics, and work progress. A total of 27 respondents out of 35 respondents said that taking a quiz about Islam could help them learn Islam. From the questionnaire, the researcher makes a problem formulation that contains what the functional and non-functional requirements of the application are and whether these needs can be realized in an Android-based application. In this study, the waterfall method is used in developing its application. At the requirements analysis stage, a general description of the system will be identified, user identification, functional requirements analysis which is also depicted in use case diagrams and use case scenarios, and non-functional requirements. At the design stage, sequence diagrams, class diagrams, operation design, data design, and interface design will become a guide in implementing the application. At the implementation stage, the system implementation and interface implementation will be explained. After the application has been completed, there is a testing phase. This testing phase goes through two tests, validity testing and usability testing. In testing the validity, black box testing is used, and the results are 100% valid. In the usability test, the System Usability Scale (SUS) is used. The System Usability Scale test results obtained a total SUS score of 927.5 and an average SUS of 77.29.

Abstract

Swimming is a sport which done in water, either in fresh water or sea water. There is somewhat problem in choosing a swimming pool based in people's interest due to many available swimming pools in Malang city. Each swimmer in a group who had different preference on swimming pool also complicates the process of choosing pool among groups.There are three factors which affects people's interest in choosing swimming pool such as distance, ticket price, and pool's rating. Therefore, the solution to choosing swimming pool is by developing an Android based group decision support system. The system generates swimming pool group recommendation using Topsis Borda method. The system also uses criterias such as distance, ticket price, and pool's rating as reference for Topsis method. Distance criteria provided by measuring distance between user's location and swimming pool's location using GPS, thus the developed application is a location based service. The generated recommendations displays informations such as pool's name, a photo, distance between user and pools, ticket price, and pool's rating. Blacbox testing on implemented system reached 100% of functional validity. Algorithm validation testing is considered to be valid because the manual count and implemented Topsis Borda method count in the system shows the same results. Lastly, the usability testing on the implemented system obtained 84.5 score from five respondents. That score shows that system is on B grade, with user acceptance category as acceptable, and adjective rating as excellent on SUS Score.

Abstract

Currently, the condition of cleanliness in the river needs to be considered. Due to the lack of public awareness of the cleanliness of the river, the current cleanliness of the river is not maintained. One of the impacts caused by the lack of public awareness of the cleanliness of the river is that there is already a lot of garbage in the river. This of course will affect the people who live in the area around the river because it can cause flooding when it rains heavily or it can make them uncomfortable because of the pungent smell of garbage thrown carelessly in the river. The research with the title "Further Development of GETAS Applications (Geotagging Brantas) for Geotagging the Brantas River" will produce outputs that aim to share information about the state of the river and raise awareness of people living in the area around the river to be more concerned about the cleanliness of the river ecosystem. GETAS will use Global Positioning System sensors and cameras to map rivers.
