Abstract

Gold Shop is a business of buying and selling gold, both in the form of jewelry and in the form of bars. Transactions carried outsell and buy gold jewelry, with different buying and selling prices. In a gold shop, to sell jewelry a clerk needs to write down the weight, and draw the model in a sales letter or memorandum. The problem that occurs is the ability to draw from employees who are not the same, some can draw jewelry similar to the original, some are unclear. Jewelry letters are also sometimes lost in the hands of customers so when selling must first ascertain whether the jewelry originates from this store. Therefore, it is necessary to make an information system to facilitate the process of buying and selling gold jewelry. The system is made based on Android because it can utilize the mobile phones of each employee. The system is made using the Rapid Application Development method, to get the final result of an android-based application.

Abstract

The limitations of developing high-tech communication systems cause the area of people who can use this service to be uneven. One technology that can be used for areas not yet reached by this high-tech communication service is to use radio communication technology. Today radio communication technology continues to develop and produce an increasingly limited frequency spectrum. One way to improve the efficient use of available frequency spectrums is the transition from analog technology to digital technology. A very significant benefit in the use of digital technology is to save the use of radio frequency spectrum bandwidth with signal compression techniques. One device that still uses analog technology is a handy talky (HT). In addition to the lack of frequency spectrum efficiency, HT technology still requires a radio station license (ISR) for its use. This experiment designed a two-way digital audio communication system that was transmitted using the NRF24L01 radio frequency transceiver module on the 2.4Ghz frequency. Analog input data from the microphone will be converted into digital data through the ADC (Analog to Digital Converter) process using a microcontroller and the digital data that will be sent is first digitally modulated using GFSK modulation then transmitted digitally. On the other hand data that already contains voice information received again by another NRF24L01 transceiver is received by the Arduino microcontroller and then formed into a PWM signal (pulse width modulation) and then released to the speaker. So the method of using digital transmission can produce efficiencies in the frequency spectrum.

Abstract

Heart disease is still ranked first in the WHO most dangerous and deadly disease in the world. This is also influenced by the individual's reluctance to check his heart condition routinely. So we need an application that is able to help overcome this. SIBioS application is a mobile-based application that functions to analyze heart rate. SIBioS is useful to help with the initial diagnosis of the presence or absence of cardiovascular disorders in individuals. The method applied for data analysis in SIBioS applications is case-based reasoning. Each heart rate data obtained will be calculated the degree of closeness of the distance to the heart rate contained in the knowledge base owned. So that the individual's heart rate can be informed. The test results show SIBioS is able to provide information about the status of the heart condition tester in accordance with the real condition of the tester at the time of measurement. In addition to using the right data analysis method, the results of heart rate data analysis are also influenced by the smartwatch device which is used as a media for tapping heart rate data, gender, age, daily physical activity, individual professional status, and supporting factors when measuring the resting heart rate. Case-based reasoning analysis methods can be applied to heart rate analysis to determine the condition of a person's heart under normal conditions or the presence of cardiovascular disorders. The physical activity recommendations given by the system are determined based on the individual's heart condition.

Abstract

Chronic Disease Management Program (PROLANIS) is one of programs conducted by Indonesian Healthcare Social Insurance Organization. Prolanis program’s target is making chronic disease patient achieve the optimal quality of life through the effective and efficient health service costs and prevent any disease complications [3]. Prolanis activities consist of medical or educational consultation, reminder, club activities and health-status monitoring which is done periodically. Clinical Documentation Improvement (CDI) is a program facilitating the realization of patients’ accurate clinical-status. Prolanis application was made to monitor the health status patients periodically. An evaluation must be done especially on real-time aspect to make prolanis application perfect. This research was descriptive and quantitative analytic research with cross sectional approach by using scoring method. The research results revealed that the value of information quality on real-time aspect regarding the implementation of prolanis application on overall score interpretation was in good category (79,3%%). The highest real-time aspect was found in the patients’ identity items written on BPJS cards and the health chart was 83,3%, while the lowest item of personnel data and DM report was 73,3%. These analysis results can be used to make prolanis application more perfect so that it will fulfill the needs of CDI.
