Abstract

Pembatasan Sosial Berskala Besar merupakan salah satu peraturan yang dibuat oleh kementerian kesehatan (kemenkes) dalam rangka percepatan penanganan dan pengendalian virus covid-19. Kota Tangerang Selatan merupakan salah satu kota yang terkena dampak penyebaran virus covid-19 dan perlu untuk menerapkan mekanisme pembatasan sosial terhadap warganya. Penelitian ini memanfaatkan nilai jumlah orang dalam pemantauan (ODP), pasien dalam pengawasan (PDP), Positif Covid-19, jumlah pasien yang dinyatakan sembuh dari Covid-19, dan jumlah kematian untuk menghasilkan nilai pada sebuah kelurahan. Kemudian nilai dari seluruh kelurahan dihasilkan dan diperbandingkan untuk mengetahui kelurahan mana yang berada pada posisi tertinggi yang harus melakukan pembatasan sosial pada warganya. Metode yang digunakan pada penelitian ini adalah Analytical Hierarchy Process (AHP) yang mampu memberi bobot kepentingan pada tiap kriteria untuk menghasilkan pemeringkatan. Hasil akhirnya adalah sebuah aplikasi yang mampu memberikan peringkat seluruh kelurahan pada satu kota untuk dapat membantu mengambil keputusan dalam menentukan kelurahan apa yang harus melakukan pembatan sosial.

Abstract

The linear search algorithm is one of the most popular data search algorithms. In the process of searching data for a list using a linear search algorithm, it can be applied in an iterative and recursive way. The general view of linear search algorithms is that the iterative methods perform the same as recursive methods. However, some studies contradict this statement which may not apply in all cases. From this analysis, this study focuses on the comparison of recursive and iterative methods on linear search algorithms to find out which algorithm is the most suitable, efficient, and effective. The research was conducted using 3 case studies with data of 1 million, 10 million, and 100 million respectively. The research focuses on the results of memory usage and access time in the data search process using Big-O notation and Python programming language. The results show that the iterative linear search algorithm is more effective and efficient than recursive. Although both methods have the same Big-O complexity, the results of program execution show different results. With the results of an iterative linear search algorithm, the results of the execution time and memory usage are superior, namely, the access time and memory usage are less than the recursive method.

Abstract

Measurement of hemoglobin levels nationally was carried out invasively using the sahli method of 27.9%. Measurement of invasive hemoglobin levels takes a long time due to the chemical analysis of patient blood samples in the blood laboratory. In general, blood sampling is done using a syringe, which can cause pain and increase the risk of spreading other diseases through needle-stick wounds. Measurement of hemoglobin levels can be done using multiwavelength oximetry technique. Therefore, in this study, a non-invasive real-time measurement system for hemoglobin levels based on the internet of things was created using the multiwavelength oximetry technique with the Extreme Gradient Boosting algorithm which is integrated with Real-time Database and an android-based information system capable of mapping users using QR Code. The test results using the RMSE parameter obtained a value of 0.801085 which indicates a high category level and an accuracy of 94.91%. The information system can display real-time measurement of hemoglobin levels with a delay of 317 ms and a throughput of 3138 bps. The results of testing the oxygen saturation functionality are 0.654% with the difference in the measurement value of the highest oxygen saturation level being 1.33% and the smallest being 0.08%.

Abstract

Flood disasters can have a detrimental impact such as damage to infrastructure, materials, and loss of life. One of the efforts that can be made to carry out early detection of flood disasters is to use a flood prediction system, where this system can monitor water levels, water flow rates, and predict real-time water increases. Information is sent to every citizen using the telegram chatbot. This system is built using several sensors and integrated with Telegram. The sensors used are ultrasonic and water flow sensors. The ultrasonic sensor is used to read the water level in the range of 0-50 cm and the water flow sensor is used to calculate the flow of water entering the test container with an interval of 0-10 liters / minute. Data is sent to telegram in realtime using the firebase database through NodeMCU ESP8266 and the WiFi module. The results of reading water level and water discharge data are processed using Sugeno fuzzy logic. The results obtained in this study indicate that the average error reading from the ultrasonic sensor is 2.43% or 97.58%. The water flow sensor shows an average error of 0.206 liters/minute or the percentage of tool accuracy is 87.06 %.

Abstract

The septic tank is a temporary waste disposal site, designed to be closed, there are two holes to drain the reservoir and another hole for evaporation. Septic tanks produce hazardous gases, for example sewer gas, have a pungent odor and are flammable, if the concentration is high, causing poisoning if inhaled, if in a closed room and there is a source of fire, it can trigger an explosion. Therefore, an automation tool is needed as a warning system for the volume of the septic tank and to neutralize the sewer gas level, which has been equipped with solar panels as battery chargers embedded in it. This tool consists of HC-SR04 to measure the remaining volume capacity, MQ2 detects and measures sewer gas levels, a fan to neutralize sewer gas, a buzzer for warning. From the results of this study, the HC-SR04 detects the remaining volume from 28% to 2%, meaning that the volume of the septic tank increases, so the buzzer is active as a notification. Furthermore, MQ2 detects gas concentrations from 2ppm to 64ppm, meaning that the gas concentration increases beyond the safe limit, which is 30ppm, causing the fan to work to neutralize sewer gas levels.

Abstract

Deep learning is a branch of machine learning with many highly successful applications. One application of deep learning is image classification using the Convolutional Neural Network (CNN) algorithm. Large image data is required to classify images with CNN to obtain satisfactory training results. However, this can be overcome with transfer learning architectural models, even with small image data. With transfer learning, the success rate of a model is likely to be higher. Since there are many transfer learning architecture models, it is necessary to compare each model's performance results to find the best-performing architecture. In this study, we conducted three experiments on different datasets to train models with various transfer learning architectures. We then performed a comprehensive comparative analysis for each experiment. The result is that the DenseNet-121 architecture is the best transfer learning architecture model for various datasets.
