Abstract

Background: Parenting styles influence sleep routines and problems in children with Attention-Deficit/Hyperactivity Disorder (ADHD); sleep quality includes efficiency, latency, duration, and wakefulness after onset. This study explores the experience of implementing bedtime routines based on caregiver parenting styles and their implications for the sleep quality of children with ADHD. Methods: Qualitative study with a phenomenological approach; non-probability sampling (purposive sampling). Participants consisted of 8 caregivers (mothers, aunts, grandmothers) of children with ADHD at YPAC Surakarta; semi-structured in-depth interviews were conducted 2–3 times per participant and analyzed thematically with credibility and confirmability tests. Results: Three main themes emerged: (1) Caregiver parenting styles (implementation and influence on sleep), (2) Types of parenting styles based on Baumrind's aspects, (3) Sleep quality of children with ADHD (sleep quality, sleep problems, supporting factors). Authoritarian parenting was linked to a stable sleep schedule but had no impact on efficiency; democratic parenting influenced emotional regulation; permissive parenting had no apparent effect on sleep quality; neglectful parenting was associated with sleep-onset insomnia without a clear cause. Conclusion: Variations in parenting styles result in different profiles of impact on sleep quality indicators. Education and harmonization of parenting styles are recommended in pediatric occupational therapy services.

Abstract

Speech emotional recognition (SER) is one of the interesting research areas of human-computer interaction (HCI) systems. The objective of this study is to provide a basis for a basic model of Indonesian-language speech emotional recognition, which is achieved by utilizing dialogues from an Indonesian-language movie.  The process began by developing a dataset from film dialogue and grouping it into four emotion classes: angry, happy, neutral, and sad. The development of the datasheet produced 5049 data points consisting of 1202 for anger, 1228 for happy, 2075 for neutral, and 899 for sad. This study uses the Mel-frequency cepstral coefficients (MFCC) method to analyze audio features from Indonesian-language movies and employs a Convolutional Neural Network (CNN) for clustering. The process began with MFCC feature extraction. During training, an accuracy of 85.85% was achieved, and during testing, 83.35%. Based on a series of tests carried out with various improvements to the previous process, a description of this system's behavior is obtained from a confusion matrix. Angry, happy, and sad expressions are easier to recognize than neutral expressions. The behavior of neutral expressions is flat in energy levels and other features. In the future, we hope it can be developed into a cross-corpus model and applied to speakers from various cultures.

Abstract

Autopilot is a system control application on moving vehicles such as airplanes, helicopters, or boat, which serves to stabilize the direction of motion in the desired time and the programmed path's direction. the autopilot control system is controlled by a series of microcontrollers and GPS that has the function to be able to determine and the desired object. This control system is designed with electrical system controls that utilize microcontrollers, sensor  and GPS as control media. The development of autopilot prototypes is used for testing new control algorithms and the reliability of other electronic components such as sensors and microprocessors. A control system is needed to control the boat to its destination. The relatively accurate system dynamics model affects the steering performance of the autopilot system. The system in question can be considered a boat with an actuator rudder, which experiences external disturbances. this system is broadly divided into two parts: the control station part and the autonomous boat part. These two parts communicate with each other using LoRa device. The data sent from the control station to the autonomous boat is target latitude and longitude coordinates. The autonomous boat will send feedback in the form of boat latitude and longitude coordinates so that users can find out the current location of the boat. Autonomous Boat also provides feedback to the control station via LoRa in the form of boat coordinates so that users can find out the current location of the boat and whether the boat has reached the specified coordinates. The control station will send feedback from the boat to a database that can be monitored via the website to find out the boat's current condition on the website. Based on the  results that have been obtained in the analysis and testing of the system. GPS sensor used in autonomous boat Ublox NEO-7m has an accuracy level with an average distance value of 3.220921 meters with the lowest cold start time of 7 seconds.  Compass sensor used in autonomous boat CMPS11 has an accuracy level with an average value of 3.041667 degrees. Communication distance between autonomous boat and control station using LoRa with 5dBi antenna can reach 1406.79 meters in condition without obstruction between nodes.  Data delivery system can be successfully sent from user to autonomout boat and sending feedback back to user. Delay update of boat coordinate data on interface has the lowest average of 30.8 seconds. Based on turning circle test results, autonomous boat is able to create imperfect circles with a radius of 8,364 m.

Abstract

Mass circumcision often induces anxiety in children, potentially affecting their experience and recovery process. This community service initiative aimed to optimize children's mental preparedness and reduce pre-mass circumcision anxiety through educational and interactive play interventions. The activity took place in Nagwen Village, Klaten Regency, Central Java, involving 41 children aged 7-11 years. The approach employed included interactive educational sessions on the circumcision procedure, its benefits, and strategies for managing discomfort, interspersed with relevant educational games. Additionally, simple relaxation techniques and open question-and-answer sessions were implemented to create a safe and comfortable environment for the children.Observational results indicated an increase in children's understanding of the circumcision process and a significant reduction in anxiety indicators, such as restlessness and repetitive questioning. Children appeared calmer, more cooperative, and enthusiastic, and were able to undergo the circumcision procedure smoothly. Most experienced moderate anxiety with an average score of 6.97, as measured by a self-assessment questionnaire. This program demonstrates that education presented in an enjoyable manner, combined with interactive play, is highly effective in preparing children psychologically for circumcision. The recommendation for this activity is to integrate similar methods into every mass circumcision event to ensure a positive experience and support children's psychological well-being

Abstract

Understanding of environmental characteristic is a key factor in design of communication system. This paper describes an ambient  noise characterization of measurement in the shallow water ofSurabaya bay. The result showed that probability density function (pdf) of ambient noise is close to a Gaussian distribution with the mean of -2.85x10-5 and deviation standard of 9.87x10-4. Validation has been done by using mean square error (MSE) and Bhattacharya distance. Fitting between cdf of measurement result and theory was done by using MSE with the value of and Kolmogorov Smirnov test with the value of 3.9x10-4 and 4.9x10-2 respectively. In the frequency domain analysis, it is showed that in the range of 0 ~ 9 kHz has a deceasing level from -100 until -140 dB. In the frequency of 9 ~ 13.5 kHz, the spectral is flat as like a white. It can be used as a reference in decision of range frequency of underwater acoustic communication systems that will be applied.Keywords: ambient noise, statistical characteristics, underwater acoustic.

Abstract

Understanding of channel propagation characteristics is a key to the optimal design of underwater acoustic communication. Generally, modelling of underwater acoustic channel is performed based on measurement result in certain site at certain times. Different sites might have different characteristics, each of which can generally be described by a model obtained by averaging measurement results at multiple points in the same environment. This paper describes a characterization of the underwater acoustic channel of tropical shallow water in a Mangrove estuary, which has sediment up to 60 cm at the bottom. Such a channel model is beneficial for the design of communication system in an autonomous underwater vehicle, for instance. The measurement result of delay spread parameter from three different points with the distance of 14 ~ 52 m, has various values. The root mean square (RMS) of delay spread ranges between 0.0621 ~ 0.264 ms, and the maximum delay spread varies with the value of 0.187 ~ 1.0 ms. The pdf fitting shows that Rayleigh distribution describes the fading variation more accurately than Nakagami and Ricean.
