Abstract

Oxygen concentrators as a means of separating pure oxygen from free air became an item that was quite sought after when the pandemic case hit in the past 2020 to 2021. This device works by taking free air around us and then processing it by passing the air through a filter so that oxygen is separated from other gases, most of which are nitrogen. However, not all oxygen generator devices are able to filter oxygen to the maximum, this depends on the filtration material used. Most portable oxygen generator devices use synthetic zeolite as a filtration material, but have not maximally filtered oxygen, therefore in this study researchers examined the effect of using silica gel when used as an oxygen filtration medium in the same oxygen concentrator device. In the results of this study, it was found that there was an increase in the oxygen concentration from the standard media device using synthetic zeolite compared to using silica gel material, the increase in oxygen concentration that occurred increased by around 3.3%.

Abstract

In the medical world known as a tool to measure the value of blood pressure called a sphygmomanometer. There are 2 types of Tensimeter tools that are often used, namely the analog type which is the old version and the digital type which is the new version. Then it is known that the development of Android smartphones in the present is increasingly sophisticated, with the addition of various features. From the Android Tensimeter and Smartphone device, the authors plan to create a digital Tensimeter device that can detect blood pressure values and record all measurement results that have been carried out, so that at any time the patient can always monitor the value of his own blood pressure via an Android Smartphone. In this case the digital blood pressure detection tool is integrated with IOT (internet of things), so that it becomes a blood pressure detection and monitoring tool. To process data and connect to the internet, the NodeMCU ESP8266 controller is used. While the MPX5050GP sensor is used as a means of detecting blood pressure values. Then the sensor will send all blood pressure calculation data to Firebase which functions as the data storage center. In the next stage via a smartphone, all data will be accessible and monitored. Next, it can be informed that from the test results on the sphygmomanometer that was made and tests on the sphygmomanometer used as a comparison, there is a difference in accuracy of about 1 percent

Abstract

Kasus kebakaran hutan dan lahan dalam tiga tahun kebelakang terus mengalami fluktuatif, dimana dampaknya sampai memberikan kerugian triliunan rupiah. Untuk mengurangi dampak kebakaran hutan perlu adanya inovasi teknologi terkait penanggulangan bencana kebakaran. Beberapa teknologi telah banyak dikembangkan, di antaranya modifikasi cuaca dan drone pemadam kebakaran. Pada metode modifikasi cuaca tidak bisa dilakukan secara intens karena biaya operasional yang mahal, sedangkan pada teknologi drone masih dalam tahap pengembangan dan belum benar-benar diaplikasikan. Meskipun drone pemadam masih awam digunakan, namun teknologi ini dapat membantu terutama pada daerah terpencil seperti hutan. Oleh karena itu dalam penelitian ini dibangun drone yang memiliki kemampuan untuk memadamkan api dengan menjatuhkan bom air (water bomb ). Berdasarkan hasil penelitian yang didapat, drone mampu melaksanakan tugas untuk menjatuhkan bom air dengan baik, sehingga diperoleh toleransi radius keakuratan sekitar 2 meter dari titik api. Tingkat kepresisian drone juga cukup baik dengan nilai kepresisiannya sekitar 95%. Untuk penelitian selanjutnya diharapkan dapat ditingkatkan lagi keefektifan drone dengan meningkatkan dimensinya, sehingga lebih kuat terhadap gangguan angin, lebih banyak memuat bom air, serta lebih lama durasinya.Kata kunci : Drone, kebakaran, otomatis, pemadam. Cases of forest and land fires in the past three years have continued to fluctuate, with the impact resulting in losses of trillions of rupiah. To reduce the impact of forest fires, there is a need for technological innovation related to fire disaster management. Several technologies have been developed, including weather modification and firefighting drones. The weather modification method cannot be carried out intensively because operational costs are expensive, while drone technology is still in the development stage and has not really been applied. Even though fire drones are still commonly used, this technology can help, especially in remote areas such as forests. Therefore, in this research, a drone was built which has the ability to extinguish fires by dropping water bomb s. Based on the research results obtained, the drone was able to carry out the task of dropping water bomb s well, so that an accuracy radius tolerance of around 2 meters was obtained from the fire point. The drone's precision level is also quite good with a precision value of around 95%. For further research, it is hoped that the drone's effectiveness can be further improved by increasing its dimensions, so that it is stronger against wind disturbances, contains more water bomb s, and lasts longer.Keywords: Automatic, drones, extinguishing, fire.

Abstract

Sistem pendingin baik berupa pendingin ruangan, lemari pendingin, maupun pendingin udara mobil merupakan kebutuhan yang sangat penting bagi kehidupan sekarang. Namun dalam penerapannya, pada sistem pendingin ini terdapat sebagian teknologi yang memanfaatkan gas kurang ramah lingkungan seperti chlorofluorocarbon (CFC) karena dapat mempengaruhi kondisi ozon bumi, untuk mengurangi penggunaan bahan berbahaya tersebut maka teknologi alternatif berupa perangkat termoelektrik dapat digunakan. Prinsip kerja perangkat ini dalam menghasilkan suhu dingin dilakukan dengan memberikan tegangan kerja dan arus kerja tertentu serta mempertahankan sisi panas termoelektrik dalam rentang suhu serendah mungkin. Sistem untuk menjaga temperatur sisi panas ini masih jarang diperhatikan, oleh karena itu pada penelitian ini diteliti metode pendinginan mana yang baik digunakan dalam mempertahan kestabilan suhu sisi panas termoelektrik. Penelitian dilakukan dengan tiga macam variasi metode, yaitu menggunakan heatsink, heatsink dan kipas, serta menggunakan waterblock. Hasil dari penelitian ini diperoleh bahwa sistem pendingin yang mampu menjaga kestabilan suhu pendinginan adalah waterblock dengan suhu terendah yang dicapai sebesar 6,3 °C.

Abstract

E-Sport is a type of sports field that uses electronic devices such as consoles, handphones, and computers in its matches. Nowadays, this field has even been competed as a World Cup. One of the most popular games of 2024 with 100 million views on the Twitch app is Valorant. This study aims to apply the Fuzzy Analytical Hierarchy Process (F-AHP) method in determining the best players in one of the Valorant tournaments. A case study for the Valorant Champions Tour 2021: Stage 3 Master-Berlin is presented in this study. Where in 9 criteria according to coach of the Korean E-Sport team recommendation as an expert are assessed: (1) First Kill per Round, (2) Kills per Round, (3) First Death per Round, (4) Clutch Success, (5) Average Damage per Round, (6) Assist per Round, (7) Kill: Death, (8) Headshot, and (9) Round on each -each alternative player/competitor. The results of this study are the names of the best players who will be sorted based on the calculation of the total weight and also the alternative statistical values. The results showed that the player who managed to become the Most Valuable Player using F-AHP was TenZ with the highest score of 19.19. The checking in the form of accuracy is carried out by comparing the Fuzzy-AHP calculation and the expert weight value, which is 15%. The case study proves the feasibility and applicability of the proposed methodology for multiple criteria ranking problem. Future research may focus on creating a hierarchy of multilevel attributes to maximize the F-AHP algorithm.
