In this study, we designed a tool that can automatically drive the solar panel motor according to the comparison value obtained from the LDR sensor. There are four LDR sensors for comparison that are used as a reference tool to move towards the brightest light intensity. From this solar panel, the power will be stored in the battery which at the same time drives the motor so that the rays obtained are more optimal and faster for charging the battery. From the results of the research conducted, the energy efficiency in a day is 9 percent from normal conditions without using optimization. It is hoped that this tool can help the community to use alternative renewable energy sources that are more effective and efficient.

With the link and match carried out in schools with industry, schools will be able to know the quality of their graduates and further information can be used to improve the learning curriculum.Currently, Ihya Ulumuddin Vocational School is conducting a tracer study still using the manual method with paper, when their alumni come to school and the results are not optimal. Completing a study tracker with this method is only able to track less than 15% of the number of graduates each year so that the picture of graduates of SMK Ihya Ulumuddin is very lacking. This data tracking study must also be submitted to the Director General of Vocational Schools at the end of each year and the school always has difficulties in providing this data. From this problem, it is said that the creation of a telegram robot application that is connected to the tracer study web application is the solution to the implementation of this tracer study. The creation of this system begins after building the system with the SMK and the application is complete, trials and implementations are carried out after the alumni graduate. Workshops and training on tracer studies were also carried out to support the implementation of this Telegram-based tracer study system. From the results of this community service, a total of 74% of the graduates were obtained in 2021. With the telegram robot that has been implemented, the tracer study implementation will assist in answering tracer study questions, making it easier to collect data on alumni of SMK Ihya Ulumuddin in an effective and efficient manner in every year.

Health media and excellent facilities undoubtedly read a positive impact on the development of society, especially at this time. BPJS, as a government health media for the people of Indonesia, of course, must bring change and be a solution to the imbalance of health services for small and medium people. Sentiment analysis of BPJS products is one solution to get information on the active role of the community as the primary user of their health products. Sentiment analysis is carried out by utilizing social media as the primary basis for data collection. In this study, the initial stage taken was data collection and continued to do Post Tagging on community tweet data. Furthermore, these data are classified again using the Naïve Bayes model to obtain optimal results. The results of the study note that BPJS health services get an accuracy rate of 70% negative for payment topics and 72% positive for information topics, and get a 65% score likely from users in using BPJS services as their health service.

In the implementation of this system, two tests were carried out, namely QoS testing when without proxy management and when using proxy management. From the two tests, the performance will be compared by doing data compilation using the VQ manager software. The QoS parameters to be taken are delay, jitter, packet loss and throughput. From the measurement it is known that when the VoIP server serves <= 3 calls simultaneously, the MOS value between the managed system (MOS = 3.7) and the system without management (MOS = 3.7) is almost the same because the value of delay and packet loss in the system without management and systems with management did not differ much, namely 107 ms and 83 ms, and the packet loss value was the same, ...

Each of these topologies has advantages and disadvantages. So, a study is required to find out in which topology can VoIP be implemented optimally. In this research, VoIP is implemented in several topologies and furthermore the performance measurements are carried out for each topology. VQ manager is installed in order to measure the VoIP performance. For the server, we used Elastix and for the node implementation network topologies, we use several access points. From the results of the research, the performance of VoIP implemented in the star topology produces QoS that is better than other topologies with a delay value of 185 ms, 18 ms jitter, and 1% packet loss. This happens because in the star topology, all packets are distributed centrally. It is expected that the results of this research can be used as a reference in the application of VoIP technology in several types of topologies.

This resulted in a decrease in the productivity of livestock, cattle. Early monitoring needs to be done to avoid problems through monitoring tools for temperature, heart rate, and internet-based location of things (IoT). The monitor receives the value through the paired sensor and is sent to the web server. Users or breeders get information about the condition of farm animals and observe changes in value through graphs through the android application. The system built is able to receive values in a short interval time (10 seconds) so that the value obtained is the most recent value. Based on observations on the graph, the user can identify drastic changes, both decreases or increases, in the temperature and heart rate of the animal's condition and take precautions as early as possible.

We provide results of an investigation of the applicability of 6LoWPAN with RPL mesh networks for home and building automation use cases. The proper selection of Trickle parameters and neighbor reachable time-outs is important in the RPL protocol suite to respond efficiently to any path failure. These parameters were analyzed in the context of energy consumption w.r.t the number of control packets. The measurements were performed in an Automated Physical Testbeds (APTB). The results match the recommendation by RFC 7733 for selecting various parameters of RPL protocol suite. This paper shows the relationship between various RPL parameters and control traffic overhead during network rebuild. Comparative measurement results with Bluetooth Low Energy (BLE) in this work showed that 6Lo with RPL outperformed BLE in this use case with less control traffic overheads.

Logistics delivery in the form of medicines and food has been hampered, and this is acknowledged by the Indonesian government, which experienced many obstacles when it had to reach an isolated location due to land transportation lines being cut off. So it was designed an Unmanned Aerial Vehicle (UAV) or drone that can deliver survival kits to some places that are isolated due to natural disasters autonomously. Flight orders will be made through the Mission Planner software, which is then sent to the drone using 433 MHz telemetries. Survival kits carried by drones will be dropped using a servo to a predetermined location. The work of Vertical Take-Off Landing (VTOL) for Drop Kits has successfully carried out a mission to deliver survival kits to 4 different locations in one flight. By using the 433 MHz Telemetry, the drone can trave...
