Abstract

Stock is a promising investment and very flexible, investors can sell their stock at any time either part or all of their stock. The high potential yield offered is what makes the stock so famous among the investors. However, the level of participation of the Indonesian people in investing in the stock market is still very low. Fluctuating stock prices are also one of the factors people are reluctant to become stock investors. Therefore, investment in stocks requires a good analysis so that investors can increase profits, one of them is by predicting stock prices from time to time so that future stock prices can be predicted by conducting technical analysis. In this study, forecasting is done using one of the artificial neural network methods, namely Feedforward Neural Network (FFNN) which is trained using the Particle Swarm Optimization (PSO) method. PSO algorithm is considered capable of replacing the Backpropagation algorithm in training networks. The error rate from forecasting results is calculated using Mean Absolute Percentage Error (MAPE). In the test the smallest MAPE value is 1,793% and fitness value is 0.98239 with 4 input layers, 2 hidden layers, and 1 output layer on the network architecture.

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.

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.
