Abstract

The noise pollution in residential areas adjacent to double-track railways can significantly disturb the comfort and well-being of residents. The noise originates from passing trains on these double-track railways. The research problem aims to compare the noise levels in the residential area with the standard noise threshold and evaluate the effectiveness of a noise barriers based on waste material called sustainable noise barrier. The effectiveness of reducing noise levels for communities residing near the dual railway lines. The sustainable noise barrier is constructed using waste cardboard and sawdust as sound absorbers for reducing noise from passing trains. The objective of the research is to analyze the noise levels in the residential areas near the dual railway lines, referring to the noise threshold value specified in Kep.MenLH No.48 of 1996, which is 55 dBA. Additionally, the research aims to assess the effectiveness of the sustainable noise barrier in mitigating noise pollution in these residential areas. The research employs a quantitative experimental method, following the SNI 8427 of 2017 standard for measuring residential noise pollution and determining the sustainable noise barrier's effectiveness using Insertion Loss (IL) and Sound Transmission Loss (STL) measurements in both laboratory-scale and existing conditions (alongside the double-track railways). The research findings indicate that the noise levels in residential areas adjacent to dual railway lines exceed the threshold value, reaching 78.08 dBA. However, the sustainable noise barrier proves to be effective in reducing noise pollution by 27 dB at a frequency of 1,000 Hz in the residential areas neighboring the double-track railways. This research suggests that limiting noise disturbances in residental areas bordering railway lines is one solution with noise barriers.

Abstract

Breast cancer is a leading cause of death among women. Early detection helps prevent the spread of cancer to other organs, thereby reducing serious risks. This characterization aims to determine the potential of the TF Mini Lidar sensor if used as an early detection tool for breast cancer. Basically, this characterization uses a data-based approach. The method used in this study is to position the TFmini and HC-SR04 sensors in a fixed and stable position, after which the reflective object is positioned at a predetermined distance according to the distance to be used when detecting breast cancer, which is at a distance of 51-100 cm. PLX daq version 2.11 was used to facilitate data collection. The characterization of this sensor is based on the standard deviation, relative standard deviation, error and accuracy. This study concludes that the TFmini lidar sensor has a high potential to be used in breast cancer detection devices as a contour detector. This is in accordance with the measurement accuracy value of the tfmini sensor of 99.87%. However, additional sensors, such as cameras, are needed to obtain better contours and visual images.

Abstract

Batuk merupakan salah satu indikator kondisi pasien pengidap penyakit infeksi saluran pernafasan akut (ISPA). Teknologi terkini memiliki banyak metode untuk mendeteksi batuk diantaranya analisis gelombang suara batuk langsung, penggunaan Frequency-Modulated Continuous Wave radar (FMCW) atau jaringan saraf tepi konvolusi dan sebagainya sebagai acuan deteksi suara batuk namun masih belum pada tingkatan pengukuran beruntun dalam bentuk intensitas deteksi batuk tiap waktu. Pada penelitian ini telah dilakukan uji coba alternatif deteksi intensitas menggunakan Mel Frequency Cepstral Coefficients (MFCC) pada platform Edge Impulse untuk mengetahui nilai akurasi deteksi intensitas batuk ISPA. Penelitian ini dilakukan dengan membuat dataset batuk ISPA, membuat pemodelan MFCC pada design Impulse dan pengembangan library mikrokontroler. Library ini diunggah pada mikrokontroler untuk dilakukan uji langsung deteksi batuk beruntun dengan variasi tanpa jeda, jeda 5 detik dan 10 detik dari kompilasi 50 suara batuk. Hasil deteksi diakumulasi dengan nilai confidence level di atas 50% dianggap sebagai batuk dan dihitung nilai akurasi dari rasio jumlah batuk yang terukur. Pada penelitian ini dihasilkan akurasi pengukuran suara batuk tanpa jeda, jeda 5 detik dan 10 detik sebesar 18%, 34% dan 62%. Cough is an indicator of the condition of patients with acute respiratory infections (ARI). Latest technology has many methods for detecting cough, such as analysis of direct cough sound waves, use of frequency-modulated continuous wave radar (FMCW), convolutional peripheral nerve networks, etc., as a reference for cough detection, but still not at the continuous measurement level in the form of cough detection intensity each time. In this study, an alternative intensity detection test will be tested using the Mel Frequency Cepstral Coefficients (MFCC) on the Edge Impulse platform to determine the accuracy of the intensity detection of ARI cough intensity. This research was carried out by creating an ISPA cough dataset, doing MFCC modeling on the Impulse design, and developing a microcontroller library. This library is uploaded to the microcontroller for a direct test of continuous cough detection with variations without pause of 5 seconds and 10 seconds from a compilation of 50 coughing sounds. The detection results accumulated a confidence level value above 50%, which was considered a cough, and the accuracy value was calculated from the ratio of the number of coughs measured. In this study, the accuracy of cough sound measurement without pauses, pause of 5 seconds, and 10 seconds was 18%, 34%, and 62%, respectively.

Abstract

Bipolar disorder is a mental health condition that causes extremely dramatic mood swings, from very high (mania) to very low (depression). Physically, mood changes can be identified from variations in sound frequency. However, early detection of individuals suspected of having bipolar disorder remains a challenge due to the limited availability of tools and healthcare facilities. This research aims to design a bipolar disorder detection tool based on anomalies in the frequency of conversational sound waves using the MAX9814 sensor as a preventive measure for bipolar disorder, with the novelty of the research being its connection to IoT, enabling real-time monitoring of bipolar patients' emotional conditions. The system design uses Arduino Nano as the data processor, and ESP8266 module for IoT connectivity, with testing method conducted on ten respondents with five variations of emotion combinations. The testing method was performed on  10 people (5 men and 5 women) aged 20–40 years, who recited sentences combining variations of depression and mania. The research results show that the device is able to detect changes in voice frequency with an average error of 5% and an accuracy of 95%. The range of sound frequencies indicative of bipolar disorder is 190–355 Hz, with the following patterns: anger < 320 Hz, happiness < 300 Hz, sadness and fear > 240 Hz, especially if negative sounds are the highest. In individuals with bipolar disorder, voice frequencies can change suddenly by more than ±50 Hz within a single sentence. These findings prove that the developed tool has high sensitivity in detecting emotional changes based on voice frequency and can be used as a supporting instrument in the early detection of bipolar disorder efficiently and sustainably.
