Abstract

The use of cooking oil repeatedly and beyond the normal limits (waste cooking oil) can cause variety of dangerous diseases to human health such as heart failure, high risk of diabetes, coronary heart disease, and others. However, the use of waste cooking oil is still high today. This is shown from the results of research in Makassar which is poor and rich people use the same cooking oil for frying as much as 61.2 percent use it twice, 19.6 percent use it three times, and 5.4 percent use it as four time. Based on the problem, it is necessary to have an automation system for classifying the frequency of the using cooking oil, so it can be used for the frequency classification of the use of cooking oil that has been used several times (waste cooking oil) accurately. In this study, the parameters used are the color and turbidity level of cooking oil. Determination of cooking oil classification is based on color and turbidity level of oil obtained from TCS3200 color sensor readings and sensor photodiode by Arduino Uno microcontroller by using Bayes methods. This method is chosen because it is one of the classification method that is quite simple, easy to understand, and has high computing speed. From the results of the tests performed, it is known the percentage error reading TCS3200 color sensor is 1.9% and photodiode sensor can work well. So, if the cooking oil is more turbid, the value of the photodiode sensor is smaller. Furthermore, the test system using Bayes methods with the amount of training data is 65 data and test data is 35 data obtained an accuracy of 71.42% with a system of computing time on average over 13.144 seconds.

Abstract

Electricity is major requirement in today's society. As an important source of energy for household, industrial even government. The increasing demand of electricity itself caused waste of energy. The energy use can be monitored by Kwh meter, to determine how much elecrity that has been used in room is not yet possible. Electricity monitoring usage system in the room using NodeMcu and MQTT (Message Queueing Telemetry Transport) would be a right solution. NodeMcu microcontroller as MQTT client publisher is using C++ program and using PubSubClient library. Then we perform a test to measure system performance of each node for monitoring electricty used in the room. There is a different value of amphere when we conduct the test that is 0-03 ampere when there is no electronic devices activity and 0.17 ampere when there is an activity of electronic device. It is possible to send the data using mqtt and the results can be displayed in grapchical form. At each node 1, 2, and 3 the diffrence is 1.50463 - 6.92544 watt-hour when the hair conditioner at level 1, iron and laptop is on, 1.4475-4.3209 watt-hour when the hair dryer at level 2, iron, and laptop is on and 0.094254-2.981733 watt-hour when all of the electronic devices is off.

Abstract

Malang raya is one of regions which becomes the main objective place to visit because it has many tourism places. The thing which has to be noticed is determining the tourism schedule, every tourist must choose the shortest distance and time to be able to reach that destination because they can save the time. To reach that destination, it is used greedy algorithm with knapsack problem to assist the optimation process against searching the shortest traveling time and how many tourism places which can be visited from the possessed time. Time allocation which is possessed by the user to tour is used as an integrity in calculating this application, while the traveling time at each tourism locations which are also used as an integrity is time data which is gotten from google maps. With thats data, the application with greedy algorithm will calculate the most optimal location to be visited with the time which belongs to the user. According to the result of testing application with ten sample of problem cases gets accuracy result 90% from two models of greedy algorithm calculation in searching location which can be visited by the allocation time which is owned. While the result of optimal tour accuracy that is visited is 0% from the first model of calculation and 80% from the second calculation.

Abstract

One of the problems in computer network is load balancing. The emergence of Software Defined Network (SDN) architecture is expected to be a new paradigm in addressing issues related to load balancing on traditional networks. The flexibility gained from separation between control plane and data plane on the SDN architecture makes it feasible to develop technologies that hard to implement on traditional networks. In this research, a load balancing algorithm is developed based on the SDN architechture. An SDN controller that is connected to an SDN switch will sends messages to each server based on the specified time interval to get the CPU and memory utilization and response time from each server. Those parameters are used to determine the load of each server. The SDN switch will then split request from client to server with smallest load. Load balancing algorithm's performance will then be compared to similar algorithms on server clusters with same specification (homogeneous) and server clusters with different specifications (heterogeneous). The result found that the proposed algorithm is able to distribute requests from clients to servers based on status of the server and perform better than similar algorithms on server clusters with different spesifications (heterogeneous).

Abstract

Software requirements engineering is crucial in the software engineering process. One of the main causes of software requirements engineering failure is that the stages are not done quite well. The structuring and clearly defined semantic will make the requirement spesification easy to be understood and validated. Linguistic based modeling method and ontology be used for modeling specification and its validation base. Sistem Penilaian Prestasi Kerja Dinas Kominfo Kota Malang is used as case study in this thesis. The requirement specification which is obtained in the development process is modified and modeled into semantic model. DITA (Darwin Information Typing Achitecture) is used as semantic method which work for documenting the requirements in scenario format with additional ontology annotations. The additional ontology function is to be the reference from DITA to ontology or vice versa. It aims to facilitate the requirements understanding during the maintenance process. The requirements validation and verification is using the ontology method by applying the query to the requirements. The query results show the completeness, consistency, and correctness status toward the requirements. The benefits of performing the validation and verification to the requirements using this method are the requirements which have errors can be detected very soon and easily with the level of completeness, consistency, and correctness up to 100%.
