Cilia are motile or sensory organelles present on many eukaryotic cells. Their formation and function rely on axonemal microtubules, which exhibit very slow dynamics, but the underlying mechanisms are largely unexplored. Here we reconstituted in vitro the individual and collective activities of the ciliary tip module proteins CEP104, CSPP1, TOGARAM1, ARMC9 and CCDC66, which interact with each other and with microtubules and, when mutated in humans, cause ciliopathies such as Joubert syndrome. We show that CEP104, a protein with a tubulin-binding TOG domain, and its luminal partner CSPP1 inhibit microtubule growth and shortening. Another TOG-domain protein, TOGARAM1, overcomes growth inhibition imposed by CEP104 and CSPP1. CCDC66 and ARMC9 do not affect microtubule dynamics but act as scaffolds for their partners. Cryo-electron tomography demonstrated that, together, ciliary tip module members form plus-end-specific cork-like structures that reduce protofilament flaring. The combined effect of these proteins is very slow processive microtubule elongation, which recapitulates axonemal dynamics in cells.

Published: January 2025

The current study uses the Chernobyl disaster optimizer (CDO), a new metaheuristic optimizer, to identify the seven unknown parameters of solid oxide fuel cells (SOFCs). The procedures of the CDO is based on physical behavior of the elaborated radiations from the well-known Chernobyl disaster according to their mass, speed, frequency, and degree of ionization. The sum of square errors (SMSE) among the estimated and the real measured output voltage datasets of SOFCs is minimized employing the CDO. Set of boundaries of the SOFC’s process is taken into consideration with the problem formulation. SOFCs stack’s model is examined at 800οC and 900οC and its performance is confirmed. The CDO extracts more precise SOFCs’ parameters compared to other competitors. The CDO’s convergence patterns and the SOFCs unit’s performance are studied and proved at steady-state by comparing its results to a number of recognized algorithms under varied operating scenarios. A significant SMSE’s values of 3.46 µV2 and 7.38 µV2 are attained at 800οC and 900οC, respectively by the CDO. As a result, the polarization principal curves of the measured and estimated voltage datasets are checked and verified with very close matching. The dynamic behavior of the SOFCs stack is examined in relation to direct load, electric networks, and superconducting magnetic energy storage devices (SMES) for additional validation and illustration. The role of the SOFCs stack in controlling the active and reactive power delivered to the network and direct load is investigated using two controllers: one to control the inverter, which converts the SOFC’s dc output to the main network, and the other to control the SMES. The Simulink/MATLAB environment is used to indicate the validity of the proposed framework under both steady-state and dynamical conditions. The comprehensive assessments show that the CDO capabilities are very effective when used with microgrids.

Published: January 2025

Emotion regulation plays a crucial role in responding to daily stressors. While intrapersonal emotion regulation has received significant attention, the role of interpersonal emotion regulation remains understudied. This study aimed to explore the associations between intrapersonal perseverative cognition (i.e., rumination and worry) and interpersonal perseverative cognition (i.e., co-rumination), in the context of daily negative events. A daily diary study was conducted with a sample of university students (N = 178). The study comprised a baseline survey assessing trait-level variables, followed by a diary study where participants were sent an approximately two-minute-long survey every evening for 10 consecutive days. The findings indicated that daily co-rumination was associated with daily intrapersonal perseverative cognition, even when controlling for trait-level worry. The association between intra- and interpersonal perseverative cognition was stronger in the presence of daily negative events. Our findings indicate a need for further investigation into the contemporaneous relationship between co-rumination and intrapersonal rumination/worry, to ascertain their unique or joint adverse effects on mental health, especially within the context of daily negative events.
Mobility of South America’s transcontinental drainage divide and shrinkage of the Paraná river basin linked to lithologic and geodynamic controls
Authors: Crelier Caio , Zumba Adriana , Peifer Daniel , Val Pedro
Published: January 2025

The South American Transcontinental Drainage Divide (TDD) is roughly oriented NE-SW from its Atlantic termination in SE Brazil to its NW termination in the limits between the southwestern edges of the Amazon Craton and the Andean Foreland. Based on a weak spatial coincidence with 90 − 70 Ma igneous intrusions, the origin and stability of the TDD have been attributed to intraplate magmatic activity. Using geomorphic analysis of drainage divides, we infer an overall southward migration of the TDD, even in areas with constrained uplift associated with intrusions. Most of the TDD is also the main drainage divide of the Paraná River Basin (PRB). Our analysis of the PRB divides reveals wholesale basin shrinkage, consistent with the southward migration of the TDD. We infer that the basalts of the Serra Geral Group induce topographic inversion of the PRB. Additionally, the PRB’s thicker continental crust contributes to its higher elevation. Non-uniform dynamic subsidence rates since 50 Ma likely lowered relief in the basin headwaters near the TDD and enhanced across-divide relief asymmetry. Together, these internal and external factors keep the PRB elevated, with low relief, and make it topographically vulnerable to long-term drainage area loss. These base-level controls explain the position and mobility of the TDD.

Purpose:

Children develop social-pragmatic understanding with the help of sensory, cognitive, and linguistic functions by interacting with other people. This study aimed to explore (a) associations between auditory, demographic, cognitive, and linguistic factors and social-pragmatic understanding in children who use bilateral hearing aids (BiHAs) or bilateral cochlear implants (BiCIs) and in typically hearing (TH) children and (b) the effect of the group (BiHA, BiCI, TH) on social-pragmatic understanding when the effects of demographic, cognitive, and linguistic factors are controlled for.

Method:

The Pragma test was used to assess social-pragmatic understanding in 119 six-year-old children: 25 children who use BiHAs, 29 who use BiCIs, and 65 TH children. The Pragma test is a standardized test that requires answering socially and contextually demanding questions with varying focuses and thus enables a comprehensive assessment of social-pragmatic understanding. Associations between auditory, demographic, cognitive, and linguistic factors and the Pragma test performance were analyzed. Between-groups differences in the Pragma test performance were analyzed while statistically controlling for the effects of factors that were associated with the Pragma test scores.

Results:

The BiHA users who had better unaided pure-tone average hearing thresholds had better social-pragmatic understanding. A higher level of maternal education and nonverbal intelligence were associated with a better social-pragmatic understanding in the BiHA and BiCI groups. Linguistic abilities correlated strongly with social-pragmatic understanding in all groups. The deaf and hard of hearing (DHH) groups differed from the TH children in social-pragmatic understanding even after the effects of maternal education, nonverbal intelligence, and linguistic skills were controlled for.

Conclusions:

Despite early diagnosis of hearing loss and intervention, many DHH children are still at risk for social-pragmatic difficulties. Several factors may associate with social-pragmatic understanding in DHH children, which highlights the importance of a wide-ranging, multidisciplinary assessment, and the planning of focused, assessment-based interventions.
Fast and low‐cost determination of prostate‐specific antigen using paper‐based immunodevice modified with Cu@CuS@Au NPs nanocages
Authors: Duan Yi , Wu Qi , Lin Jiangtao , Duan Yourong , Wang Qi , Li Yuanyuan
Published: January 2025

In this study, the authors designed a paper‐based electrochemical immunodevice modified with copper embedded in copper sulphide hollow nanocages wrapped with Au nanoparticles (Cu@CuS@Au NPs) for the specific detection of prostate‐specific antigen (PSA), aiming to advance point‐of‐care testing. The large specific surface area of Cu@CuS nanocages enables efficient capture of biotin antibodies, leading to the direct amplification of the signal through the inhibition of electron transport in the redox process of Cu, eliminating the need for universal redox electron mediators. Additionally, Au NPs on the surface of Cu@CuS can accelerate charge transfer and conjugate with anti‐PSA. The hierarchical morphology and structure of Cu@CuS nanocages were characterised using scanning electron microscopy and transmission electron microscopy. The fabrication process of the immunodevice was monitored using cyclic voltammetry and electrochemical impedance spectroscopy analyses. PSA was sensitively detected using differential pulse voltammetry on this proposed immunodevice within a linear range from 0 to 100 ng/ml (R2 = 0.996), achieving a low detection limit of 0.077 ng/ml. In addition, the practicality of the developed immunosensor has been proven by successfully detecting PSA in human serum samples obtained from clinical settings. The integration of electrochemical sensors and microfluidic devices holds promise for developing cost‐effective approaches in clinical immunoassays.

Published: January 2025

The gas-phase metallicity is a crucial parameter for understanding the evolution of galaxies. Considering that the number of multiband galaxy images can typically reach tens of millions, using these images as input data to predict gas-phase metallicity has become a feasible method. However, the accuracy of metallicity estimates from images is relatively limited. To solve this problem, we propose the galaxy parameter measurement residual network (GPM-ResNet), a deep learning method designed to predict gas-phase metallicity from photometric images of DESI. The parameters of photometric images are labeled with gas-phase metallicity values, which were obtained through spectroscopic methods with a high accuracy. These labeled images serve as the training dataset for the GPM-ResNet method. GPM-ResNet mainly consists of two modules: a multi-order feature extractor and a parameter generator, enhancing the ability to effectively extract features related to gas-phase metallicity from photometric images. The σ of Zpred – Ztrue is 0.12 dex, which significantly outperforms the predicted results of the second-order polynomial (σ=0.16 dex) and the third-order polynomial (σ=0.16 dex) fit using the color-metallicity relation on the same dataset. To further emphasize the superiority of GPM-ResNet, we analyzed the predicted results on various network architectures, galaxy sizes, image resolutions, and wavelength bands of images. Moreover, we explored the mass-metallicity relation and recovered the relation successfully by utilizing the predicted values, Zpred. Finally, we applied GPM- ResNet to predict the gas-phase metallicity of spiral (EXP) galaxies observed by DESI, resulting in a comprehensive catalog containing 5 095 815 pieces of data.
Temperature and density profiles in the corona of main-sequence stars induced by stochastic heating in the chromosphere

Published: January 2025

All but the most massive main-sequence stars are expected to have a rarefied and hot (million-Kelvin) corona like the Sun. How such a hot corona is formed and supported has not been completely understood yet, even in the case of the Sun. Recently, a new model of a confined plasma atmosphere has been introduced and applied to the solar case, showing that rapid, intense, intermittent and short-lived heating events in the high chromosphere can drive the coronal plasma into a stationary state with temperature and density profiles similar to those observed in the solar atmosphere. In this paper we apply the model to main-sequence stars, showing that it predicts the presence of a solar-like hot and rarefied corona for all such stars, regardless of their mass. However, the model is not applicable as such to the most massive main-sequence stars, because the latter lack the convective layer generating the magnetic field loop structures supporting a stationary corona, whose existence is assumed by the model. We also discuss the role of stellar mass in determining the shape of the temperature and density profiles.
La conservation hermétique des céréales : comment les avancées de la recherche ont été ignorées au XXe siècle en France
Authors: Fleurat-Lessard Francis
Published: January 2025

Pendant la première moitié du XXe siècle, le stockage des grains à la ferme s’est effectué essentiellement en sacs conservés en grenier. À partir des années 1930 sont apparus les premiers silos de stockage de type coopératif. Ces structures de conservation en vrac ont rapidement été confrontées à des difficultés de préservation de la qualité en cas de conservation à long terme. Il en a découlé un besoin de recherche, notamment pour comprendre la dynamique de prolifération des moisissures de stockage et de multiplication des insectes dans ces structures de grand volume. Après la deuxième guerre mondiale et la découverte des premiers insecticides organiques de synthèse, leur utilisation s’est généralisée. À partir de 1960, pour faire face aux nombreuses avaries dues à l’échauffement des grains stockés trop humides, des laboratoires spécialisés dans l’étude des facteurs de détérioration des grains stockés ont été constitués dans tous les pays développés producteurs de céréales, avec un même objectif : améliorer la connaissance sur le fonctionnement dynamique de l’écosystème du stock de céréales. À partir des années 1970, ces groupements de chercheurs se sont organisés en équipes pluridisciplinaires venant présenter régulièrement leurs résultats dans des conférences internationales. Dès 1980, ils se sont intéressés à la conservation des grains en atmosphère modifiée ou sous inertage, en substitution aux traitements insecticides et pour limiter les risques liés aux moisissures à mycotoxines. En France, les acquis de la recherche sur le stockage hermétique ont été ignorés pour plusieurs raisons : i) le manque de relais efficace entre recherche et application des innovations, notamment pour les producteurs-stockeurs en agriculture biologique ; ii) le verrouillage par le secteur commercial de l’option consistant à remplacer les traitements correctifs des avaries par une démarche écosystémique de protection antiparasitaire intégrée ; iii) l’absence de valorisation des systèmes experts permettant une meilleure maîtrise des dérives de qualité pendant la conservation.

This research focuses on exploring indigenous fungi from industrial waste discharged into rivers. Sampling was conducted in the Ciliwung and Krukut rivers at several points in the waste disposal environment. The purpose of this study was to identify the presence of fungi that have the potential to degrade industrial waste components from the waste-polluted climate itself. The method includes isolating fungi by dilution from sediment and water samples, which are grown using potato dextrose agar (PDA) media. After the isolation, characterisation was done to identify the fungus types found. The results of this study showed the presence of 5 fungal isolates that have great potential in degrading industrial waste. These findings suggest that local fungi from Jakarta landfills could potentially be used for bioremediation as a solution to reduce the impact of hazardous waste on the environment. Waste management using fungi supports the achievement of SDG 6 (clean water and sanitation) by improving water quality through the degradation of harmful compounds, SDG 12 (responsible consumption and production) by providing sustainable waste management methods, and SDG 14 (marine ecosystems) by prevent river pollutants from reaching the sea to maintain the health of the aquatic ecosystem.

Published: January 2025

The micro-food web decomposer is the primary community of the soil food web responsible for organic matter transformation in terrestrial ecosystems, providing minerals for plant growth. Their composition, however, depends on the quality of organic matter as their basal resource, which, in turn, determines the available nutrients in the soil. Our study examined the micro-food web community over three different organic matter compositions, differentiated by their organic carbon and total nitrogen contents. We compared the communities of composted organic matter that differed in their C to N proportion. Given in percent, they were 40:40:20, 50:40:10, and 60:30:10 of high C to N, medium C to N, and low C to N, respectively. After four weeks of finished composting, samples were obtained and enumerated for bacterial number, fungal biovolume, protozoan (amoebae, testate-amoebae, ciliate, flagellate), and nematode abundances. Our data show that a 20% change in low quality organic matter (high C to N ratio) suggests an 82.47% decline in bacterial abundance but a 22.15% increase in fungal abundance. These findings emphasize the importance of the organic matter Carbon and Nitrogen content in determining the composition of the micro-food web communities and the potential to manage the intended micro-food web community during the composting process for soil health improvement.

The Neocaridina genus is one of the atyidae families that inhabit lakes, tributaries, ponds, rivers, and streams. Two species of Neocaridina have become popular in the Indonesian aquarium, namely N. denticulata and N. palmata. Neocaridina species are affected by ectoparasites, the same as another ornamental shrimp. The ectoparasites are to be found on the shrimp gills and surfaces. This study aimed to identify ectoparasites on the gill, and surfaces and, subsequently, to evaluate the infection rate between two species regarding sex, and organs. Neocaridina species were collected from the Purbalingga fish market. The univariate analysis described the variable and significance difference among the factors at a level (p<0.05). Two hundred samples were examined, and one hundred samples from each species. The results showed that 78% N. denticulata and 78% N. palmata were infected with no significant difference in the infection of the two species. Ectoparasites are found in two species namely sessile bdelloid rotifers, Vorticella sp., and Zoothamnium sp. Sessile bdelloid rotifers were detected in males and females of the two species. Higher infection by Vorticella sp. and Zoothamnium sp. were recorded in females of the two species. Sessile bdelloid rotifers were highly infected on the surfaces/cephalothorax of the two species while Vorticella sp. were highly infected on the gills of the two species. Zoothamnium sp. was not detected on the cephalothorax of the two species, these parasites species were host-specific to the gills of the two species. Vorticella sp and Zoothamnium sp. were not infected on the cephalothorax of N. denticulata.

The harmful effect of K2Cr2O7 has been reported in animals and humans but the mechanism in exerting such an effect is unclear. An experimental study applying a completely randomized design was conducted to evaluate the impact of in vitro exposure to K2Cr2O7 on MDA level, cell density, and cell viability in Osteochilus. vittatus testis. The testis fragments were cultured in DMEM supplemented with 10% FBS and 5% pen-strep for 24 hours and 72 hours at 29°C; 5 concentrations of K2Cr2O7: 0µg.mL-1, 0.125 µg.mL-1, 0,250 µg.mL-1, and 0.50µg.mL-1 were tested. The result showed that the exposure of 0.500 µg.mL-1 K2Cr2O7 for 24 hours did not significantly affect the MDA level (p>0.05), but it significantly reduced cell density (p<0.05) and cell viability (p<0.01). Exposure to 0.500 µg.mL-1 K2Cr2O7 for 72 hours significantly increased the DMA level (p<0.05), cell density (p<0.05), and cell viability (0.01). These results indicated that K2Cr2O7 induces oxidative stress, cell proliferation, and cell survival of Osteochilus vittatus testis.

The study aimed to determine the quality of frozen semen sexing with percoll medium and Bovine Serum Albumin (BSA) in Dorper sheep and Saanen goats. The research was designed based on the experimental method, as the main plot is livestock (M) consisting of two levels, namely M1 (Dorper sheep) and M2 (Saanen goats), while as a sub plot is sex separation medium (S) consisting of percoll medium (S1) and BSA medium (S2), each treatment combination was repeated 3 (three) in the form of semen collection. The results of analysis of variance showed that the quality of unsexed semen in sample and separation medium did not show significant differences (P>0.05). It means that the quality of unsexing semen in Dorper sheep and Saanen goats both using percoll medium and BSA was relatively the same. The results showed a decrease in the quality of spermatozoa Y from post-thawing sexing frozen semen compared to the quality of fresh semen unsexing in Dorper sheep for motility, viability, concentration respectively by 16.55; 4.52; and 20.34% and an increase in abnormality of 103.37% compared to fresh semen unsexing. While in Saanen goats there was a decrease in the quality of X spermatozoa from post-thawing sexed frozen semen compared to the quality of fresh unsexed semen for motility, viability, concentration of 19.23; 21.91; and 17.08%, respectively, and an increase in abnormality of 110.52%. However, the quality of sexed frozen semen in Dorper sheep and Saanen goats was still within the limits that can be used for artificial insemination programs. It can be concluded that to obtain Y spermatozoa in Dorper sheep, and X spermatozoa in Saanen goats using 45:60% percoll medium and 5:15% BSA medium separation.

Adolescence is a transitional period from childhood to adulthood, marked by rapid physical, psychological, and social changes that can impact the development of sexual behaviours, including the potential for engaging in risky sexual behaviour. This study aimed to identify factors that influence risky sexual behaviour in adolescents in Indonesia's Rural Areas. This study is a quantitative research with a cross-sectional design. The sample of this study was active students in Banyumas Regency, one of Indonesia’s rural areas in 2022. A probability sampling technique with proportional stratified random sampling was used and obtained 452 respondents. The data was collected using questionnaire sheets. Data were analyzed using the Chi-Square and multiple logistic regression tests. This study shows that dating experience, dating status, age, religiosity and access to technology are the most influential factors for risky sexual behaviour in adolescents in rural areas, with dating experience having the greatest influence as indicated by an OR value of 6.67. Although religiosity plays a role, it is insufficient to protect adolescents from risk. Comprehensive sexual health education and consistent monitoring of technology usage are urgently needed to reduce risky sexual behaviours among adolescents in rural areas.

The prevalence of hypertension in Indonesia increases with age. Examination of vital signs such as resting pulse and respiratory rate are parameters of hypertension morbidity. One alternative therapy for hypertension is slow, deep breathing exercises. This study aimed to determine the effect of slow, deep breathing exercises on hypertensive patients' resting heart rate and respiratory rate. The research design used was pre-experimental with one group pretest and posttest on 26 hypertensive patients at Posyandu Lansia Waras Winangun, Banyumas. The sampling method used was the total sampling technique. Participants were treated with slow, deep breathing exercises three times a week for six weeks. Resting heart and respiratory rates were examined before and after the intervention of slow, deep breathing exercises. Data analysis of the results in this study used the Wilcoxon non-parametric test. Slow deep breathing exercises significantly decreased resting heart rate (p=0.001), but the respiratory rate was not found to decrease significantly (p=0.209). It can be concluded that the administration of slow, deep breathing exercises affected the resting heart rate but did not affect the respiration rate.

In Indonesia, indigenous religious believers have faced stigma for decades, primarily due to past restrictions that prevented them from including their religious identity on official documents. This exclusion has led to bullying, discrimination, and feelings of inferiority among these communities. Many believers perceive their religious identity as the cause of the discrimination they face, which is reinforced through negative social interactions. This study explores the role of parents in building social resilience among indigenous religious believers, focusing on how parent-child communication fosters this resilience. Using a phenomenological approach, the research gathered data through interviews and observations with 15 participants from various indigenous religious communities in Indonesia. The findings reveal that parents are crucial in transmitting indigenous religious practices and values through both verbal and non-verbal communication. By fostering pride in their faith, parents help their children build resilience, allowing them to maintain their religious identity in the face of societal challenges and negative external influences. The study has broader implications for policies promoting social inclusion, reducing inequalities, and strengthening family and community roles in supporting marginalized groups. It contributes to Sustainable Development Goal (SDG) 10, advocating for structural changes that promote diversity and social equality.

Published: January 2025

Coconut sugar has become a leading commodity in Purbalingga Regency. It is a substitute product for granulated sugar with a low glycaemic index, so it is a product with high demand. This research aims to analyse (1) coconut sugar productivity and (2) coconut sugar production scale. The analysis methods include multiple regression analysis using the Cobb-Douglas function approach to analyse productivity and return to scale analysis to analyse production scale (CRS, IRS, or DRS). The research results show that (1) capital and coconut sap production have a positive effect on coconut sugar production, while the number of labours has no effect and (2) the scale of coconut sugar production shows decreasing return to scale (DRS). These findings are proof that the Covid-19 pandemic is still having a big impact on their business. Therefore, the local government must take a major role in supporting this leading industry, such as providing technical and financial assistance along with intensive mentoring so that their businesses return to normal.

Authors: Raharjo Agus , Hapsari Retnaningrum Dwi , Sugeng Esmara , Saefudin Yusuf , Ismail Noorfajri
Published: January 2025

This article discusses how terrorists/terrorist organizations use the internet to carry out their actions; the roles and responsibilities of stakeholders in countering cyberterrorism. This research is qualitative research with a normative juridical approach and research on law as law in action, a non-doctrinal and empirical social science study. The threat from terrorists/terrorist organizations is not only to the physical infrastructure of the internet itself, but also to the spread of radical ideas on social media. Radicalism is the root of terrorism that is now widespread on the internet. These acts of terrorism threaten the achievement of the SDGs, especially in areas 3, 4, 8, 9, 10, and 16. Efforts to counter these actions within the framework of the national counter-terrorism policy are through counter-radicalization. The sophistication of terrorists/terrorist organizations in utilizing the internet requires an equally sophisticated response in combating and countering cyberterrorism, combating them requires simultaneous integration of stakeholders in this field, namely law enforcement, academia, businesses (private security industry), society/community, media and internet users.

Published: January 2025

The relationship between Regional Heads and the Regional People's Representative Council (DPRD) is crucial for the success of Indonesia’s decentralized governance. Despite Law No. 23 of 2014 aiming to enhance regional autonomy and collaboration, political conflicts, stemming from differing affiliations and agendas, often hinder this relationship. Such conflicts can lead to gridlocks, policy delays, and budgetary standstills, especially in politically charged regions. Furthermore, the power imbalance, with Regional Heads controlling regional resources, weakens DPRD’s oversight functions and governance effectiveness. In contrast, regions with political stability show that cooperation between Regional Heads and DPRD can improve governance and public service delivery. This study, using a normative legal approach, identifies three key pillars—equality, transparency, and accountability—as essential for fostering a strong relationship between Regional Heads and DPRD. Findings suggest that these pillars reduce political tensions, strengthen oversight, and ensure continuity in public services. To address ongoing governance challenges, the study proposes two conflict resolution mechanisms: a vertical mechanism involving the Ministry of Home Affairs for mediation and oversight, and a horizontal mechanism emphasizing regional coordination forums. These mechanisms highlight the need for detailed regulations to guide conflict management, contributing to governance stability and supporting Indonesia’s decentralization goals.

Indonesia has implemented the MBKM policy to improve the skills and abilities of graduates through adaptable and hands-on learning. Nevertheless, the execution of the plan has faced numerous challenges, requiring a thorough assessment. Furthermore, the study aligns with crucial Sustainable Development Goals (SDGs), including SDG 4 (Quality Education), as it seeks to improve educational quality to achieve national development goals. The objective of this study is to examine the effectiveness of the MBKM policy implementation and identify the elements that either facilitate or impede its success at Universitas Jenderal Soedirman. The study employs a qualitative descriptive technique, utilising in-depth interviews, observations, focus group discussions, and document analysis. The data were analysed using the interactive methodology developed by Miles, Huberman, and Saldana. The findings demonstrate both favourable effects and difficulties in applying MBKM, encompassing concerns regarding curriculum adaptation and doubts regarding its efficacy in attaining human resource development objectives. This study enhances existing knowledge on implementing policies in higher education and offers significant insights for policymakers and university administrators. These discoveries can provide valuable insights for improving future policies and strategies aimed at maximising the success of the MBKM program in cultivating highly skilled human resources in Indonesian higher education institutions.

Published: January 2025

Bengkalis Island and Bengkalis Regency generally have peatlands that are mostly abandoned, prone to fires and prone to landslides due to abrasion. The Environmentally Concerned Malay Youth Association (IPMPL) created a movement to cultivate Cratoxylum Arborescens (gerunggang) as a native plant to prevent fires. This research aims to explore community-based environmental communication for disaster mitigation in peatlands. The method applied in this research is a case study. The research results show that the environmental campaign is based on the problem of peatlands which are vulnerable to fires and landslides due to abrasion. IPMPL plays a role in campaigning for peatland conservation through gerunggang cultivation. This movement contributes to mitigating fire disasters in peatlands and abrasion landslides. Environmental communication based on Forest Farmer Groups (KTH) contributes to reducing the risk of land fires and can improve the community’s economy. This community collaborates with several parties such as: the Ministry of the Environment, Forest Management Units (KPH), district and provincial governments, as well as farming community groups in campaigning for environmental messages. This collaboration contributes to reducing the problem of environmental damage on peatlands. However, IPMPL has not maximized the use of social media to publish all its activities.

Human activities are predominantly conducted indoors, making it equally important to ensure good indoor air quality as it is to maintain outdoor air quality. The quality of indoor air is partly determined by the levels of PM2.5 (particles with an aerodynamic diameter ≤2.5μ m) and PM10 (particles with an aerodynamic diameter d ≤10 μm) and humidity. The Pediatric Intensive Care Unit (PICU) is a space that must maintain high air quality because it is continuously occupied by pediatric patients and healthcare personnel 24 hours a day, 7 days a week. In this study, the indoor air quality in the PICU Arifin Achmad General Hospital (AAGH) in Riau Province, Indonesia, was observed using a descriptive observational study with a longitudinal and time-series design. The results of this study demonstrated that the PM2.5 levels decreased from 9.25 µg/m³ in the morning to 3.3 µg/m³ in the afternoon, whereas PM10 levels decreased from 17.7 µg/m³ in the morning to 7.8 µg/m³ in the afternoon. Additionally, the air humidity increased from 60.7% in the morning to 61.4% in the afternoon. In conclusion, the observations from this study indicated an increase in air humidity from morning to afternoon and the normal particulate matter levels.
