<![CDATA[Many studies and research are continuously being developed to improve the quality and capability of video compression. Compression of the video is done with the help of a video codec, in the video there are several types of video codecs including VP8 and H.265. These two codec models have very high resolutions for video. In implementing video calls, the determination of the codec has not been able to prove the results of video quality. To be able to know the quality of the resulting video, codec quality testing can be done through pixel conversion which can later be analyzed for video quality when making calls. In this study, a comparison of the performance of the VP8 and H.265 codecs will be carried out using the FreePBX server as a Raspberry Pi-based Video Call Server and is expected to find out which codecs are appropriate to use for the video call process. Based on the results of the comparison study between the two codecs, it shows that the value of the QoS parameter includes packet loss codec H.265 with a resolution of 720 lower with a value of 0.95%. The throughput value of the VP8 codec with 720p resolution is higher with a value of 1275.36 Kbps. The delay value in the H.265 codec with VGA resolution lower with a value of 6.78 ms. The results of the pixel conversion test show that the H265 codec has a higher PSNR value of 55.64 dB and a lower MSE value of 5.66.]]>

<![CDATA[VoIP servers provide several types of codecs including iLBC and Speex codecs, each type of codec has a different capacity and quality- different. So that in the process of choosing a codec implementation, VoIP becomes one of the things that affect the quality of communication. The iLBC and Speex codecs are intended for high quality but bitrate . By comparing iLBC and Speex communication, VoIP hoped that the better performance between the two codecs would communicate VoIP based on Quality of Service (QoS) and analyze the audio results of VoIP for voice quality analysis using the voice comparison method using Matlab. Based on the results of the research between the iLBC and Speex parameter value QoS including delay codec speex is smaller than iLBC codec of 31.12 ms. The jitter value of the iLBC and speex is the same, namely 0.01. The packet loss value of the iLBC codec is smaller than the speex codec of 6.18%. The results of the sound quality test in matlab using the sound comparison method showed that the delta amplitude codec speex value was smaller than iLBC codec of 0.00004551 volts.]]>

<![CDATA[The drop in COVID-19 patients in Indonesia from January to February 2022 made many companies prepare policies to no longer enforce work from home. At the office, we can interact and meet other people directly and it is possible to be exposed to Covid-19 that could potentially become a new wave of COVID-19. This effect poses a serious risk to all people who come into contact with COVID-19-infected individuals or are close to them. The major course of action that may be performed when someone has COVID-19 is self-isolation and tracking anyone who is around or has a health condition associated to COVID-19. We require an iOS-based COVID-19 diagnosis expert system application to track the health status of everyone around us because we are unable to know the health status of everyone. The application uses artificial intelligence technology in the form of an expert system to check health conditions. The expert system replaces the role of the expert with the certainty factor method. This app should be used every time before entering a potentially crowded place to clarify tracking by using maps feature. In addition to COVID-19, this expert system can also diagnose diseases that have the same symptoms as Typhoid Fever and Pneumonia. The results of the expert system are in the form of diagnosing the user's health condition based on the symptoms given with a confidence level of up to 0.9999952130944 or 99.99952130944% for COVID-19, 0.9676 or 96.76% for Typhoid Fever, and 97% for Pneumonia.]]>

<![CDATA[A room with too humid conditions can cause mold and bacteria to multiply quickly. The humidity level of the room can be influenced by several factors such as the temperature level and the intensity of light entering the room. Even so, the use of lighting as a sterilizer is currently still lacking in reducing the level of humidity in the room. For this reason, it is necessary to develop technology in the form of a control system for the use of led and ultraviolet lamps in the study room by utilizing the IoT system, so that it can turn on the lights and utilize electrical energy. In this study, the Internet of Things system was applied as a control for Web cameras, Gyml 8511, DHT11, and BH1750 sensors. Data from the sensor will be sent from Arduino uno to a local server, namely raspberry pi 4 using NRF24L01. The communication system between nodes is designed with a mesh topology that can determine the fastest route in the process of sending information. The result of this research is monitoring on the web display that displays the condition of the class and the condition of the lights. From the experimental results, it is found that the mesh communication system can work well.]]>

<![CDATA[Energy has been a human need since ancient times which has been an indicator of prosperity. However, that doesn't mean there won't be problems. The longer the petroleum reserves are getting depleted, so sooner or later humans must make more use of non-fossil alternative energy. An example is solar energy whose availability will never run out. Therefore, the application of Solar Power Generation (PLTS) technology to utilize its energy potential. The goal of the project is to develop a system for integrating solar power with electrical grids that can track the voltage and current of the applied load. The PZEM004T sensor produces an accuracy of 99.4 percent on the voltage variable test, which compares favorably with the ACS712 current sensor's accuracy of 97.8 percent. The lowest light intensity measured in the current variable test is 24351 lux with an output voltage of 17.32V at the time range between 4-5 pm, and the highest is 103901 lux with an output voltage of 18.9V at the time range between 11-12 am. Accuracy is 98.5 percent with light loads and 99.2 percent when the charger is used. Relays' ability to switch between resources has been tested, and the results have met expectations.]]>

<![CDATA[According to the results of a 2022 survey conducted by the Association of Indonesian Internet Service Providers (APJII), internet users in Indonesia continued to increase from 175 million to 220 million users of the total population of Indonesia. The increase was driven by the need for communication during the Covid-19 pandemic in the last two years. Most internet users are on the island of Java, followed by the islands of Sumatra, Kalimantan, Sulawesi, Bali-Nusa, and Maluku-Papua. PT. Tentrem Sejahtera is one of the Inter-City In-Province bus companies based on the island of Java, precisely in East Java. The ordering and payment process is still done manually or offline. Consumers who want to buy tickets must come directly to the terminal, to an authorized agent who has been appointed or do it directly when boarding the bus and make transactions in cash. Where when making manual or cash payments sometimes you have to wait a few minutes to issue money and wait for the ticket given by the conductor, while the level of security in payments is very less, so it is less efficient in this sophisticated era. In addition, there are still unscrupulous brokers at several bus departures who sell tickets that do not match the specified price. This study used the e-wallet electronic payment model method, with a mobile payment system for QRIS-based bus fares. With the National Mercant ID (NMID) listed on the QRIS display, a receipt will be issued on the Thermal Print for proof of payment.]]>
