Abstract

Indonesian is a country where a third of its population works from the agricultural sector, especially rice fields. Most farmers expect maximum yields without knowing the soil fertility with the factors that support this fertility. Factors such as soil pH, soil moisture, soil temperature and various other factors. Especially the factors can also change at any time that could interfere with the process of plant growth if farmers do not pay attention to these changes. With the developing technology, we can make it easier to monitor soil pH, soil moisture and soil temperature using the YL-69, DS18B20 and soil pH meter sensors. The data taken by the three sensors will be accommodated in the sensor node and then sent to the gateway via the websocket and forwarded to firebase and then displayed to the web interface. Testing is done using quality of service to determine the performance of the network performance from delivery speed, packet lost during delivery, and time interval of each delivery. Then the performance test results obtained, namely the throughput of H-1 to H-3 is 12.11 bps, 10.88 bps, and 16.13 bps. Packet loss from H-1 to H-3 is 0.4%, 0.3%, and 0.2%. The delay from H-1 to H-3 is 0.12 s, 0.09 s, and 0.09 s. The tool's function test works successfully with data taken from the three sensors that can be displayed on the web interface.

Abstract

Some factories have been using gas as a source of combustion fuel for production purposes, resulting in emissions from the combustion process. Most of the gas used for the fuel source consists of methane gas or CH4. Meanwhile, emissions from the combustion system are in the form of carbon monoxide gas or CO. One of the technologies in the industrial sector that can observe gas leaks and air quality in industrial areas is the Wireless Sensor Network technology. Wireless Sensor Networks are a set of nodes that are arranged in a wireless network to monitor the surrounding environment and able to communicate with each other through protocols, one of which is Bluetooth Low Energy. Compare to the other protocols, there are some advantages that Bluetooth Low Energy has such as better power savings, being able to send data quickly, easy configuration, and a wide coverage. Therefore, the researcher decided to conduct a research by applying Bluetooth Low Energy in real life, by observing temperature, humidity, CH4 gas and CO gas levels. Through Bluetooth Low Energy, Raspberry Pi is able to send observations to the clients. In this study, two scenarios are used to test the delivery performance of Bluetooth Low Energy. The scenarios are changes in distance without obstacles and changes in distance with obstacles. The test results showed that the change in distance without obstacles and with obstacles had an average total delay of 0.0752 ms and 0.1587 ms.

Abstract

There are a lot of medical facilities that use information technology to simplify data storing, one of those technologies is an electronic health record. In Rafael Clinic Malang, the health record process that was done there is still not efficient enough because the process still uses manual writing and excel. The procedure is carried out at least three times, that is, writing the data in a patient visitation book, patient ID, then rewrite the data to excel. The health record data are still kept in patient ID so it need some times to search for the ID, not including if the ID is missing or damaged. Based on those problems, the author developed a web-based electronic health record system. The purpose of this research is to know the result of requirement analysis, design, implementation, and the testing result of the developed system. Waterfall model is used as the development method, which has the principle that the next development stage cannot be carried out if the previous stage has not been completed. 47 functional requirements and one non functional requirement were obtained through requirement elicitation, in which security being the non functional requirement. Designing was done using object oriented approach, which produces sequence diagram and class diagram. Database, algorithm, and interface designing is also done. Unit testing using the white-box method gives 100% valid results. Acceptance testing with the black-box method for 80 test cases got 100% valid results. Integration testing gives 100% valid results. Security testing of electronic payments and login sessions has met expectations.

Abstract

Indonesia is a country that is rich in natural resources, there are many pine trees that produce sap. Pine tree sap has many uses in the cosmetic, antiseptic and pharmaceutical industries. But pine sap produces a waste effect. There are still many things that need to be improved on the processing of gondorukem for wastewater treatment. Especially in the disposal section, it is not possible to predict a good standard of liquid waste disposal. The standard for wastewater disposal has several parameters such as pH, temperature and turbidity of the waste. With IoT technology, it makes it easier for us to reduce the pH, temperature and turbidity of the waste by using a pH meter water sensor, DS18B20 and Turbidity. The data of the three sensors are collected to the sensor node, then sent to the gateway via a websocket, then forwarded to firebase which will be displayed on the web interface. Testing uses Quality of Service, to determine a network speed performance when sending, which is useful for knowing the time of each delivery and packets lost during delivery. The water meter's pH sensor function, DS18B20 and Turbidity, worked well during research. Then obtained from the test results based on the throughput h-1 to h-4 testing is 17.01 bps, 20.89 bps, 19.83 bps and 18.86 bps. For packet loss h-1 to h-4, namely 0.1%, 0%, 0% and 0.%. Then the delay h-1 to h-4 is 0.08 s, 0.07 s, 0.07 s, and 0.07 s.

Abstract

Malang City is one of the most populous cities in Indonesia. Poverty data collection is often a problem in determining poverty support beneficiaries, and some of the problems arising from poverty data collection are not found for residents without E-KTP, human resources are not eligible, and the data collection process is still done manually using paper, which requires a longer selection time. The PROMETHEE II method, Weighted Product, and Simple Additive Weighting are used in decision making by decision-makers. The system test is made by providing different criteria for each variable and indicator, and five tests were performed to measure the accuracy of the system, and the test results obtained 4 tests that obtained 100% results for each variable. The family variable in the second test tube can reach 20% and for the individual variable, it can reach 60° in the third data test. The level of accuracy obtained as a result of these tests is that the differences in the distribution data used are not evenly distributed. This will cause the level of accuracy obtained to fluctuate based on the data for each reference weight. Testers, the level of accuracy of the site can explain the results more accurately.

Abstract

Stroke constitute disease that can cause death and disablement, but the number of patient is still very high. So that new stroke cases do not continue to grow, needed a way for early detection of stroke risk so that people who have the potential to suffer a stroke can take preventative. However, stroke is a complex disease that shows different symptoms between one patient and another. Moreover, the cause of stroke between one person and another person can also be different so that early detection of possible risk of stroke in a patient should be made with care.Decision support systems built using FK-NN are considered capable of assisting early detection of stroke risk quickly, thoroughly, and objectively.support system built with FK-NN will observe to stroke risk factors and calculate using framingham risk score, the method commonly used by doctors to calculate the risk of cardio vascular disease.The system then classifies data using the FK-NN method in the class of low risk stroke, moderate risk stroke, and high risk stroke. The results of this study indicate that the FK-NN is able to properly assist early detection of stroke risk, which resulting in an accuracy of 61.1% when K is 4 and the percentage of training data is 50% of the entire data set.

Abstract

Providing the best service is a priority for the Faculty of Economics and Business Universitas Brawijaya (FEB UB) to give a comfortable and safe impression. If there are services provided that are not in accordance with the services that should be provided, both lecturers, educational staff and FEB UB guests can submit complaints through Whatsapp social media which is managed by the operator and admin. After the complaint is received by the operator or admin, the complaint is filtered according to the complaint category and then forwarded to the Whatsapp group according to the complaint category. This process has a flow that is quite complicated and takes a long time. Besides that, the submitted complaints are not kept by FEB UB, where complaints can be used as evaluation materials in each semester to improve better service. From the existing problems, a system development was carried out to manage service requests and employee complaints. The development of this system uses the Prototyping method. The process in system development starts from the stage of literature study, needs analysis, design, implementation, and testing. The results of the needs analysis were carried out in 2 iterations at the prototyping stage, there were 7 actors, 35 functional needs, and 1 non-functional requirement. The system was developed using the Javascript programming language using the Express.js framework and Bootstrap. Testing uses unit testing and integration with 100% results for all tested test cases and testing using validation testing with 100% pass results. While testing compatibility, the functionality contained in the system can be run on all browsers but still has some issues with the appearance and performance of the system.

Abstract

Photovoltaic (PV) array under partial shade condition due to clouds or the shadow of buildings will make PV array get uneven irradiation. PV array with uneven irradiation will form multiple peaks on characteristic curve and will make the characteristic curve complex. In under partial shade condition, the conventional maximum power point tracking (MPPT) method can't reach to global MPP. MPPT based on meta-heuristic method can solve the PV characteristic curve problem that have multiple peaks. One of the meta-heuristic methods that can be used is Particle Swarm Optimization (PSO). The PSO method is used to solve the problem of the global maximum power under partial shade condition. The PV system consist of PV array, boost converter and MPPT implemented in MATLAB/Simulink. Experiments were carried out on 3 possible shadow patterns on 5 series connected moduls. The experimental results shows that overall MPPT PSO obtained an average tracking efficiency of 99,4275% with an average tracking time of 1.04 seconds. MPPT PSO can track the maximum power under partial shade condition.

Abstract

Leukemia or what we usually call blood cancer is cancer that attacks white blood cells. The healing method which is still being debated in the medical world and the difficulty in preventing this disease, makes this disease a deadly cancer. Lack of experts and information about leukemia often results in delays in diagnosing leukemia. The high cost of medical treatment by doctors has made many people try alternative treatments, which are relatively more affordable. However, even alternative medicine does not ensure a cure for the patient, which in turn requires the patient to be taken to the hospital again and in most cases the cancer has reached an advanced stage. Based on these problems the authors conclude and raise a problem into an expert system study to diagnose leukemia which is expected to help sufferers and doctors in need. The expert system for diagnosing leukemia which is made using the Fuzzy Tsukamoto method based on 100 patient training data with 10 attributes, has been tested with expert diagnosis having a success rate of 90%. The difference in the results of system diagnosis with experts from 30 test data is 3 data so that there are 27 correct data from 30 test data.
