Authors: Shige Koki , Takeda Naoyuki , Terashima Osamu
Published: December 2023

In this study, an attempt to reduce the flow-induced noise generated by heating, ventilation, and air-conditioning (HVAC) systems for commercial electric vehicles using feedback active noise control with real-time filter update in frequency domain was conducted to improve the quietness
of a running vehicle. In active noise control (ANC), the frequency-domain gradient descent algorithms (FDGD) to adapt the noises was studied. In the experiment, air conditioner noise was measured using a microphone placed at the driver's left ear and referenced by a microphone at a map lamp
for ANC. Results shows that in the 1/3-octave band, the sound pressure level in driver's left ear was 7.2 dB smaller at maximum when the control was operated. The effective frequency bands were between 50 and 150 Hz. Its reduction was 4.7 dB on average.
An auditory virtual reality of meeting room acoustics using wave-based acoustic simulations: A content for intuitive understanding of room-acoustics control effect by sound absorbers
Authors: Okazawa Kazuha , Okuzono Takeshi , Yoshida Takumi
Published: December 2023

Recently, wave-based room acoustic simulation technologies are becoming a realistic option as a small-room acoustics design tool and a virtual indoor sound environment creation tool for research and education. The present paper shows an auditory VR meeting room content, which makes
us easily understand how sound absorbers play an essential role in creating a better acoustic environment. Unity creates the 3D virtual reality model, and a binaural room-acoustic auralization is realized by a hybrid technique combined with Ambisonics and the head-related transfer function
using RIRs computed by a high-speed parallel wave-based room acoustics solver. The VR meeting room is constructed under various acoustic treatments with sound absorber modeling by wave-based material models.
On the Hybrid Modelling of Rigid Sonic Crystal Embedded in Plenum Chamber at Low Frequencies Using the Effective Medium Approach and Finite Element Method
Authors: Lam Wai Kit , Krynkin Anton , Tang Shiu Keung
Published: December 2023

This study explores the application of homogenization schemes in modelling acoustic wave propagation in a finite array of circular scatterers embedded into a 2D cavity. The cavity is integrated into the 2D waveguide attached to the cavity inlet and outlet. Square-lattice sonic crystal
(SC), composed of rigid and radially symmetric circular cylinders, is used to represent the finite array in this study. The model is aimed at informing the novel designs of plenum windows with superior soundproofing performance. The sound transmission performance is analysed with hybrid numerical
simulation using the Finite Element Method (FEM) and homogenization scheme. A theoretical homogenization method based on the Effective Medium Approach (EMA) is reviewed and implemented on the modelling of the SC array inside the cavity at low frequencies and then implemented in FEM. Comparison
of the transmission loss (TL) reveals a high degree of matching between settings with and without homogenization at low-frequency range. It is observed that performance of the hybrid model maintains a high degree of matching provided the cavity modes are dominated by a single characteristic
scale in the low frequency. This includes the case of a narrow plenum chamber with only a single cylinder placed inside the cavity with a width of one lattice constant. This homogenization method is proven to be more computationally efficient in FEM compared to the modelling of exact geometry
of the problem.
A review of the effect of various type of artificial sounds to odontocetes
Authors: Akamatsu Tomonari
Published: December 2023

Reactions of bottlenose dolphins, Pacific white-sided dolphins, false killer whales, Risso's dolphins, Dall's porpoises to artificial underwater sounds were observed for developing countermeasures to reduce by-catch on gill nets. Related papers published during 1980-1995 in Japan were
re-visited. Various sound projectors having dominant frequencies from 2 kHz to 200 kHz with source levels reaching up to 200dB re 1μPa. Reactions of dolphins and porpoises to the sounds were observed in a pool, a net enclosure, or an open sea. Clear escaping reactions from a sound source
were observed by sounds with exposed level above 170dB at the subject animal. Reactions to sounds below 160dB were not stable. The dolphins got accustomed to the sound after multiple projections. On the other hand, frequency and amplitude modulated sounds seemed to be effective even if the
sound pressure level was about 120dB. Efficacy of acoustic pingers to control wild dolphins and porpoises was limited. The exposure level to change behavior was estimated above 170dB that depends on the source level of a device and distance to the animal. Acclimation for the sounds by dolphins
and porpoises were not negligible. Avoiding successive transmission and amplitude/frequency modulations induced behavioral reactions.
Expert decision support system to improve the analysis of airframe noise measurements
Authors: Spehr Carsten
Published: December 2023

For the localization and estimation of aeroacoustic sources on complex aircraft models in wind tunnel measurements beamforming and related methods are well known. The task of the aeroacoustic experts is to identify and classify the relevant sources within these beamforming maps. In
this paper, we present an expert decision support system to support this task. The system comprises three steps: The first step identifies aeroacoustic sources in sparse beamforming maps and extracts their corresponding spectra without manual definition of regions of interest. The second step
calculates the acoustic properties of the sources based on spectral and spatial information. The third step clusters the identified sources based on these acoustic properties. In this paper, data are evaluated based on CLEAN-SC beamforming maps of two airframe half-model wind tunnel measurements.
A variety of aeroacoustic features are proposed that capture the characteristics of the source spectra. The result of this expert decision support system is a list of all relevant sources clustered according to their acoustic behavior at different Mach numbers. The aim of the system is to
support aeroacoustic specialists in analyzing beamforming results and identifying relevant and spurious sources in-situ.

Deep Learning-based Motor Prognostics for Electric Power Steering Systems
Authors: Kim Gyuwon , Won Jongick , Lee Doheon
Published: December 2023

The electric power steering (EPS) system is a fundamental unit for modern automotive vehicles, providing motor assistance and various control functions to aid the driver's manual maneuvering. Preventing loss of assist (LoA) in advance is critical for EPS systems to mitigate fatal accidents
and maintenance costs. As part of the recent interest in intelligent software-defined vehicles (SDV), data-driven approaches have gained much attention to overcome the limitations of conventional fail-safe and maintenance strategies. However, while related works in the field have shown promising
results, they are limited to proof-of-concept studies for detecting and isolating artificially injected faults using simulation and test-bed data, which lacks relevance and poses limitations for practical in-vehicle implementation. Herein, we present a deep learning (DL)-based method to predict
the motor degradation level in an EPS system using in-vehicle data acquired from the controller area network (CAN) bus. Our approach proposes a novel multivariate transformer (MVT)-based neural twin model of the EPS system, which is trained using an adversarial learning strategy by utilizing
only the normal data. Our method can detect degradation levels down to ten percent from normal working conditions based on an anomaly detection mechanism that outperforms baseline methods in quantitative and qualitative measures.
Comparison of the effects of mental fatigue on medial olivocochlear reflex and cortical activity
Authors: Uchiyama Kandai , Otsuka Sho , Nakagawa Seiji
Published: December 2023

The medial cochlear reflex (MOCR) is assumed to protects the inner ear from acoustic overexposure. The MOCR strength assay is expected to be applied to screen for individuals at high risk for noise-induced hearing loss. However, the MOCR strength varies from one measurement to another,
and it is necessary to identify the factors that cause the MOCR variations for more accurate risk assessment. It has been reported that variations in cortical cognitive function, e.g., attention and expectation, influence MOCR strength. Here we examined the effects of mental fatigue, one of
the causes that degrade cognitive functions, on MOCR. The degree of mental fatigue was adjusted by varying the difficulty of a calculation task and investigated the effects on MOCR. To elucidate the mechanism of MOCR variations associated with mental fatigue, cortical activities were evaluated
by measuring slow vertex response (SVR). Although MOCR strength and SVR amplitude did not change significantly after the calculation task, two measures had reverse dependence on the difficulty of the calculation task; A moderately difficult calculation task increased SVR amplitude while reduced
MOCR strength. The results implicate that MOCR variations associated with mental fatigue can be attributed to cortical activity changes.
A field experiment on the effect of sound absorption installed to a highly reverberant kindergarten classroom: A second report
Authors: Kawai Keiji , Matsufuji Yuuki , Tsuru Megumi , Ishizawa Midori
Published: December 2023

An experiment in a kindergarten classroom with an excessive reverberation was reported in Internoise 2022 and this is the second report of the continued experiment conducted in the same classroom. The classroom was highly reverberant (V = 200 m3, RT = 1.0 s at 1 kHz band) because the
room was originally an outdoor space of ground floor pilotis and converted into a classroom by constructing concrete walls between the columns with the fire-resistant hard ceiling panels remained. The experiment was conducted by installing and removing sound absorbing materials on the walls
and ceiling periodically for six months. The RT with sound absorber was reduced half at 0.5 s. The indoor activity was recorded by sound and video recorders. As a result, SPL of 1-2 kHz bands, which was regarded as children's voice during free play time reduced more than the direct effect
of the sound absorption only when the sound absorption was installed first time. The SPL of 1-2 kHz when children singing together, which was assumed as voices without communication in contrast to free playing, was analyzed and the trend was similar to those in the free playing time.

Authors: Kang Min-Woo , Oh Yang-Ki , Jeong Jeong-Ho
Published: December 2023

Elevators are essential equipment in high-rise buildings. In addition to residential buildings, elevator noise that can occur in high-rise buildings such as hotels, hospitals, and offices affects residants as noise. ISO 16032 is the current international standard for elevator noise
measurement methods. Through many previous studies, the elevator noise measurement method was continuously studied. In particular, problems that are difficult to apply to high-rise buildings, in the case of high-rise apartments in Korea, have been verified. In order to solve these problems,
previous studies have set items that need improvement. In addition, improvement plans were proposed through various experiments in apartment houses in Korea. In this study, I try to determine whether the improvement plan can be appropriately applied to the improvement of the current standard,
and to find out what needs to be discussed in future research.
Localization of skin-core disbond damage in a honeycomb core sandwich composite structure using the A0 guided wave mode
Authors: Mitra Aurovinda Kumar , Joglekar Dhanashri M.
Published: December 2023

Honeycomb core sandwich composite structures (HCSCSs) find extensive applications in the marine, aerospace, and defense sectors owing to their lightweight characteristics. However, they are prone to damage due to the disbond between the skin-core interfaces, resulting in catastrophic
failure if undetected. This study aims to develop a new framework for the non-destructive evaluation (NDE) of HCSCSs numerically using the fundamental antisymmetric mode (A0) of guided wave propagation to locate such damages efficiently. The wavefield patterns clearly distinguished an intact
HCSCS from a disbond defect HCSCS. A significant amplification of the A0 mode is observed due to disbond damage. The disbond damage is localized using the total focusing method with full matrix capture (TFM-FMC) algorithm-based NDE framework. The proposed health monitoring framework effectively
detected disbond damage in an HCSCS.
Verification on prediction method of floor impact sound using vibro-acoustic coupling effect
Authors: Kim Suhong , Hwang Jaeseung , Ryu Jongkwan
Published: December 2023

The impact noise generated in concrete structures exhibits complex behavior due to the interaction between vibration and sound, making it difficult to predict. To achieve accurate predictions, it is important to consider the interaction between vibration and sound and input reliable
data. In this study, a governing equation that considers the interaction between vibration and sound was proposed and validated using relatively reliable vibration data as input. Vibration and sound data were obtained from a mock-up house built with a structure similar to that of an actual
residential building. The vibration data was analyzed using time history and modal decomposition to confirm the interaction between vibration and sound. Subsequently, the proposed governing equation was used to calculate the sound data by inputting the vibration data, which was then compared
and analyzed against the measured data. In the time history analysis, it was observed that the calculated data after 0.8 seconds exhibited relatively less attenuation, suggesting a higher damping ratio in the mock-up house than anticipated. Furthermore, the modal decomposition comparison revealed
a slight shift in the mode frequency from 43.0 Hz to 43.6 Hz, and the spectrum showed larger values in the calculated data, which can be attributed to the damping ratio. Further research on the damping ratio in residential buildings is planned to improve the accuracy of the prediction in the
vibration-sound system.
Broadband noise emission by a low-Mach low-Reynolds number propeller ingesting a boundary layer
Authors: Guérin Sébastien , Lade Tobias , Castelucci Leandro , Zaman Ismaeel
Published: December 2023

The broadband noise radiated by a low-speed two-bladed propeller immersed in a planar turbulent boundary layer (BL) is predicted by using an analytical approach developed in the past in response to a similar aero-acoustic problem. The experimental results come from two independent facilities
having analogous characteristics. Excess broadband noise is assumed to be generated by the BL turbulence hitting the propeller blades. The aero-acoustic model is based on the acoustic analogy. It accounts for the fact that vortices can be chopped several times by the blades as they pass through
the propeller. The "cigar" shape of the turbulence near the wall surface is considered in the turbulence model. If possible, the input parameters are retrieved from the hot-wire measurements carried out in the boundary layer, otherwise they are modelled. The propeller performance
is calculated using BEMT. The effect of the flat plate on aerodynamics and acoustics is ignored. The results obtained with this heuristic approach are satisfactory in the orthogonal plane but the levels are underestimated by more than 10 dB in the downstream region of the horizontal plane.
This suggests that a major effect is not captured by the current models. Measurements and predictions agree upon the fact that blade-to-blade correlations are not prominent for this configuration.
Objective evaluation of voice quality by intermittent recording of sound on English voice
Authors: Ogiso Satoki , Okuma Takashi
Published: December 2023

Continuous sound surveillance have the problem of unintentionally recording conversational content. On the other hand, if only coarse features are stored so that speech cannot be recovered, the use of the accumulated recorded information is very limited. In this study, we propose a
method to record raw background sounds while making the conversational content inaudible by periodically repeating recording and stopping. In this presentation, we will show the results of an objective evaluation using a speech recognition model by varying the ratio of recording time and the
recording stop frequency. The results showed that the recording time ratio can be maximized by selecting appropriate recording stop frequency even for the same objective voice quality.

Published: December 2023

Item response theory (IRT) is considered an improvement of the classical theory of tests to determine the educational level using the learning skills of students. The analysis of these tests together with the knowledge of different elements of the social and familiar context, makes
it possible to evaluate the educational level of countries, as well as the effect of contextual variables on learning skills levels. The IRT method considers that there is a latent unidimensional continuous variable whose determination makes it possible to establish quantitatively the abilities
of individuals and the difficulties of the questions. In this paper, we present an adaptation of this methodology to the analysis of ratings to questions in subjective rating surveys of concert halls, for experts and general public. The latent dimension (LD), provided by the IRT method, has
been determined for the surveys of different concerts in 9 concert halls of different types. For each concert hall, a map of the distribution of LD values and subjective rating responses is shown, and the effect of the different context variables is analyzed.
A fundamental study on the sound insulation characteristic of gyroid
Authors: Yano Takumi , Sugahara Akiko , Hiraguri Yasuhiro
Published: December 2023

Gyroid is a micro-periodic structure that has been observed in biological structural coloration such as butterfly wind scale. It reflects and interferes with light, producing vivid and complex colors. This study aims to apply this property to control sound waves. In this paper, we focused
on its sound insulation characteristics, and performed a basic study through the numerical analysis and experiments. The main findings are as follows: (1) The gyroid has a significant sound insulation performance in a specific frequency range depending on its size. (2) Compressing gyroid in
the incident direction further improves the performance. The gyroid samples were fabricated by additive manufacturing and their insertion loss were measured in an anechoic chamber. This result experimentally confirmed the findings explained above.
Investigation on acoustical performances of micro-perforated panel with soft boundary backing cavity
Authors: Pratiwi Radhiyah Ulfah , Prasetiyo Iwan , Agusta M Kemal
Published: December 2023

Low-frequency noise control is still an issue due to its characteristic of having a long wavelength. Therefore, attenuation requires a bulky noise control component, including an acoustic absorber. Conventional absorber materials, such as micro-perforated panels (MPP), are a candidate
to circumvent such a problem. However, the requirement of backing cavity depth causes the MPP to work under a quarter wavelength constraint. Eventually, the bulky characteristic of the absorber is persistent. Therefore, this study introduces a soft boundary condition to the MPP to enable the
system to work at a lower frequency while the associated dimensions reduce. Open gaps between the backing cavity and rigid surface realize the soft boundary conditions and double-layer MPP is considered to test such a system. The experimental result shows that the soft boundary can enhance
at low frequencies (<250 Hz) by 0.3-0.6 points. At the same time, the open gap can slightly increase the resulting absorption performance deficiency at mid-frequency.
Intelligent sniper localization technique using convolutional neural network
Authors: Dwivedi Priyadarshini , Rakesh Reddy , Routray Gyanajyoti , Hegde Rajesh M.
Published: December 2023

A reliable methodology for sniper localization utilizing a machine-learning framework has been proposed herein. The proposed work is based on the time of arrival of the shock waves (SW) in contrast to the conventional approaches, which utilized both the muzzle blast (MB) and SW. Since
the MB is susceptive to environmental disturbances, the proposed solution is robust and reliable. The SWs are captured with the 2D non-linear array, and the time delay between the microphones is approximated using the generalized cross-correlation phase transfer (GCC-PHAT). Subsequently, a
convolutional neural network (CNN) model is trained to map the input GCC-PHAT features to the sniper position. Adopting the CNN model provides robustness in the method, which also performs better in highly noisy environments. The performance of the proposed technique shows a significant improvement
compared to the conventional methods providing a motivation to be used in practical applications.
CRNN-based spatial active noise control in spherical harmonics domain
Authors: Routray Gyanajyoti , Hazare Siddhesh Bharat , Dwivedi Priyadarshini , Hegde Rajesh M.
Published: December 2023

In this work, an active noise control (ANC) in the spherical harmonics (SH) domain, along with a learning model, is developed. The traditional ANCs are built on the adaptive signal processing framework and fail in the presence of nonlinear distortions. Further, these algorithms are
limited to the horizontal plane only. In contrast, the proposed work develops the ANC in the 3D space using the SH representation with the spherical microphone array (SMA) as the error microphone. The SH decomposition calculates the SH pressure coefficients from the SMA recordings. Subsequently,
a convolutional recurrent neural network (CRNN) is trained to estimate the real and imaginary spectrograms from the SH coefficients as the input features. The output of the CRNN is the canceling signal that eliminates or attenuates the primary noise in the ANC system. A delay-compensated method
addresses ANC system latency. According to simulations and experiments, the proposed learning-based spatial ANC reduces wideband noise and generalizes to untrained noises.

Published: December 2023

This study investigated the Just Noticeable Difference (JND) and Annoyance in each octave band of impact source produced by rubber balls using an auditory perception experiment. Through a literature review, two representative spectra for the impact sounds of rubber balls were selected.
Spectrum A represents the impact sound on a 210mm concrete slab, while Spectrum B represents the impact sound on 110 ~ 180mm concrete slabs. The source levels of the rubber ball impact sound used in the experiment were given as Single Number Quantities (SNQ) of 47, 51, and 55 dB. Additionally,
variations of ±2, ±4, and ±6 dB were conducted for each octave band. The subjects' response data were analyzed using Probit regression analysis. The results showed that both Spectrum A and Spectrum B exhibited higher change rate of Annoyance in the frequency bands where
the JND results were smaller. Specifically, these frequency bands were 63 and 125 Hz for Spectrum A, and 250 and 500 Hz for Spectrum B.

Landscape tools to support the educational use of school grounds
Authors: Jákli Eszter
Published: December 2023

Recent years have seen an increasing emphasis on child-friendly concepts in landscape architecture and urban planning, as well as a growing emphasis on school grounds and environmental education, both in terms of pedagogy and landscape design. School grounds provide places for active engagement with the environment, for experiencing what is taught in class, and, are therefore of particular importance for education and for building children's connection with nature. The aim of this research is to develop a set of landscape architecture tools that can be used to promote child-friendly and education-centered design of school grounds. The research collects and organises the different school ground features, drawing on literature research, and the analysis of the Framework Curriculum. The toolkit presented in this paper lists and evaluates each feature according to its function, its relevance to school subjects and the specific knowledge or skills it can help to acquire, its space requirements and feasibility. To conclude, school grounds offer opportunities for teaching almost any subject and can therefore be linked to educational activities in multiple ways. The results of this research are to be developed into design guidelines in order to be used by designers and teachers alike, to help develop school grounds contributing to the well-being and environmental awareness of new generations.
The impact of population management on urban and rural Hooded Crow populations
Authors: Paládi Petra , Benmazouz Isma , Lengyel Szabolcs , Kövér László
Published: December 2023

Hooded Crow (Corvus cornix), originally native to agricultural areas, has become widespread in urban areas in recent decades. However, this process has negative consequences on urban animals and humans. Due to these problems, the control of urban crow populations is needed. Crows also cause significant damage to wildlife management, and are constantly being controlled in rural areas as well. In this study, we compare rural and urban populations to find out whether hunting activities have a population reduction effect. In the rural population, the reduction is carried out by weapons and traps, while the urban crows are controlled using traps only. In both sample areas, crow nests were surveyed during the nesting period. 29 active nests were monitored in the rural area in 2021, and 39 in 2022. In the urban area, 44 nests were recorded in 2021 and 35 nests in 2022. In 2021, 30 individuals were removed in the rural area, and 84 in 2022. In the urban area, 223 individuals were removed in 2021 and 144 in 2022. Results show that the number of crows removed follows the number of active nests, so that the reduction of a given year is likely to have an effect on the following year's nesting population. Because traps mostly capture juvenile birds, reducing the breeding population in the city can only be achieved in the long-term. Considering this, it is likely that increased attention to population control can effectively maintain crow populations and reduce the problems they cause.
Ecological value of wood energy plantations in the support of some animal groups
Authors: Szabó Fruzsina Magdolna , Juhász Lajos
Published: December 2023

Today, some environmental problems have reached such severe proportions that it is no longer enough to recognise them, but environmentally friendly solutions must be used to reduce them. The reduction in the area of natural forests of native species is causing problems in several ways.
This research aimed to highlight how environmental, conservation and economic interests can be reconciled. In addition to natural forests, wood energy plantations are becoming increasingly important. Energy import dependency is a problem for most countries, for which wood energy plantations can partly offer an alternative. Native forests can be protected, and their area increased where possible. Meanwhile, energy plantations can be established in areas with low agricultural productivity.
In this experiment, I studied a plantation of Pedunculate Oak (Quercus robur), a Black Locust (Robinia pseudoacacia) and a Paulownia (Paulownia Shan Tong). I selected burrowing birds and ground-dwelling arthropods as indicator groups. I did this by establishing a nesting colony and soil trapping. I wanted to demonstrate that, in addition to natural forests, wood energy plantations have a role not only in economic terms but also in maintaining certain animal groups. Soil trapping tests were carried out in all three tree plantations.
The obtained results showed that in the Paulownia plantation, the occupancy rate of nest boxes was almost 100%, while in the Black Locust plantation it was around 30%. Among the species that occupied the nesting sites, the Common Starling (Sturnus vulgaris) and the Eurasian Tree Sparrow (Passer montanus) were more abundant, while Great Tit (Parus major) was present in the Black Locust plantation. These are opportunistic species for which nesting opportunity is the most important factor, since their feeding area (in the case of the Common Starling and the Eurasian Tree Sparrow) is not typical of the nesting area. The soil trap investigations show that there are no significant differences in the composition of the arthropod group (beetles, spiders) in the study areas.

This study aims to determine the effect of the liquidity, profitability, and solvency ratios on financial distress and the difference in financial distress before and during Covid-19 in companies engaged in the healthcare sector listed on the Indonesia Stock Exchange. The analysis method used in this study, descriptive analysis, classical assumption test, regression analysis test, and hypothesis testing processed using SPSS using a sample of 13 companies by taking the 2018-2021 financial report period, where 2018-2019 is the period before Covid-19 and 2020-2021 is the period during Covid-19. The calculation model carried out by researchers using the Zmijewski X-Score provides results that there is a significant negative effect on the current ratio, a significant negative impact on the return on asset ratio, a significant positive effect on the debt to asset ratio, and there is no difference in financial distress before and during Covid-19. This gives companies a lot of consideration in making decisions because if they make the wrong decision during a pandemic, the company will be closer to bankruptcy.

Postgraduate students, especially working students, are protesting because they have to attend face-to-face lectures on weekdays for various reasons. This study aims to determine which postgraduate lecture delivery method meets the market needs (university students). The research method made use of Soft System Methodology (SSM). The FGD was conducted with twelve participants, classified into postgraduate students of Wijawiyata Management (full-time students), Young Executives (students with at least two years of work experience), and Executives (students with no less than five years of work experience). The research was conducted in March and April 2023. The results were analyzed using Role (clients, practitioners, and owners), Social (educational institutions and instructors), and Power (national policies and regulations) Analysis. This research shows that by rich picture and root definition, weekday online lectures and weekend (Saturday) offline lectures meet the market's needs and violate no Indonesian higher educational regulations. The findings also suggest that a combined lecture mode, offline and online, is more favorable to Master's degree students, hence the Indonesian government's rigorous encouragement for Distant Learning for various learning needs across the archipelago.

Latar Belakang: Stunting pada balita dapat menjadi predisposisi terjadinya masalah-masalah kesehatan lain hingga dewasa. World Health Organization (WHO) menyebutkan bahwa prevalensi balita stunting pada tahun 2022 sebanyak 149,2 juta atau sebesar 22% balita yang mengalami stunting. Salah satu program prioritas pembangunan kesehatan dalam periode tahun 2020-2024 adalah penurunan prevalensi stunting. Asupan zat gizi pada balita sangat penting dalam mendukung pertumbuhan sesuai dengan grafik pertumbuhannya agar tidak terjadi gagal tumbuh (growth faltering) yang dapat menyebabkan stunting. 43,2% balita di Indonesia mengalami defisit energi dan 31,9% balita mengalami defisit protein. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian makanan tambahan nuget tempe terhadap peningkatan BB dan TB pada balita 24-59 bulan di Desa Karangmuncang Kecamatan Cigandamekar Kabupaten Kuningan.

Metode: penelitian ini merupakan jenis penelitian Quasi eksperimental dengan desain pre-test and post-test control group. Pemilihan sampel menggunakan metode Consequtive Sampling. Sampel penelitian adalah balita 24-59 bulan di Desa Karangmuncang Kecamatan Cigandamekar Kabupaten Kuningan yang memenuhi kriteri inklusi. Jumlah sampel sebanyak 60 balita, 30 orang untuk kelompok intervensi dan 30 orang kelompok kontrol. Bentuk intervensi penelitan yaitu pemberian bahan makanan nuget tempe pada balita yang mengalami stunting. Kelompok kontrol balita hanya mendapatkan pelayanan kesehatan balita dari tenaga kesehatan setempat. Bentuk intervensinya yaitu kelompok intervensi diberikan nuget tempe selama 1 bulan setiap hari, jumlahnya yaitu 50 gram (balita > 12 bulan). Nuget tempe disiapkan setiap hari oleh peneliti dan diantarkan kerumah masing-masing sampel untuk dikonsumsi dan dimonitor jumlah yang tersisa karena tidak dikonsumsi.

Hasil: Diperoleh nilai p value = 0,000 yang menunjukkan bahwa ada perbedaan yang signifikan TB balita antara sebelum dan sesudah diberikan perlakuan berupa pemberian makanan tambahan nuget tempe. Untuk koefisien korelasinya didapatkan nilai positif dan nilai positif 0,998 untuk TB yang berarti korelasinya sangat kuat.

Kesimpulan: Terdapat Pengaruh Pemberian Makanan Tambahan Nuget tempe Terhadap BB dan TB Pada Balita Stunting.

Saran: : Pemberian PMT Modifikasi berbasis kearifan lokal  dalam hal ini nuget tempe dapat menjadi alternatif program penanggulangan stunting dan gizi kurang.
