Abstract

Stunting is a chronic nutritional problem that impairs children's growth and development. This study aims to examine the influence of agricultural production and food access indicators on stunting prevalence across 35 districts and cities in Central Java Province from 2021 to 2023. The independent variables include rice production, horticultural production, broiler chicken production, cow milk production, egg price index, and paddy field area. Panel data regression using a fixed effects model (FEM) was selected as the most appropriate analytical approach, based on the results of the Chow and Hausman tests. The results show that rice production, egg price index, and paddy field area have a statistically significant influence on stunting prevalence. In contrast, horticultural production, broiler chicken production, and cow milk production do not show significant effects. These results suggest that improving food availability alone is not sufficient; it must be accompanied by enhanced access and affordability. The study highlights the importance of localized agricultural and nutritional strategies in reducing stunting. Analysis indicates the decline in stunting prevalence in Central Java, although several areas still record high rates. Rice production, paddy field area, and egg prices index as significant factors influence stunting, highlighting the need for integrated policies that combine agricultural development with improved access, affordability, and nutrition education.

Abstract

Psychological stress plays a crucial role in modulating the immune system through complex mechanisms involving interactions between the nervous, endocrine, and immune systems. This review evaluates the impact of acute and chronic stress on immune function and the molecular pathways involved. This study employed a narrative literature review approach to explore the relationship between psychological stress and the immune system from a psychoneuroimmunological perspective. The literature review found that chronic stress has been shown to induce immune system dysregulation through activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, leading to increased levels of glucocorticoid and catecholamine hormones. These hormones influence immune cells, inhibiting the proinflammatory Th1 pathway, enhancing the Th2 response, and causing increased levels of inflammatory cytokines such as IL-6 and TNF-α. Consequently, stress contributes to an increased risk of chronic diseases such as cardiovascular disease, cancer, depression, and diabetes. Meanwhile, short-term acute stress can have adaptive immunostimulatory effects, especially in healthy individuals. The stress response is highly individualized and influenced by a person's biological vulnerability and coping capacity. By understanding the relationship between stress and the immune system in the context of psychoneuroimmunology, preventive approaches and clinical interventions can be developed to minimize the adverse effects of stress on physical and mental health.

Abstract

The coastal area of Muara Angke in North Jakarta is facing increasingly serious environmental pressures due to the destruction of its mangrove ecosystem. Mangrove forests, which previously served as natural protection against ocean waves, abrasion, and tidal flooding, are now experiencing significant degradation. This phenomenon occurs in tandem with human activities such as reclamation, land conversion, and pollution. This research aims to examine in-depth the impact of mangrove destruction on coastal settlements and assess the extent to which implemented adaptation strategies can mitigate ecological and social risks. A qualitative approach with a case study design was used in this research. Data were obtained through direct field observations, interviews with the community and stakeholders, and a review of supporting documents. The analysis was conducted using a combination of descriptive techniques and evaluative instruments such as SWOT, IFAS, and EFAS to identify the strengths, weaknesses, opportunities, and threats facing the coastal area due to mangrove ecosystem degradation. The results show that mangrove destruction has a significant impact on the environmental quality of coastal communities, primarily through increased tidal flooding, abrasion, and decreased marine catches. Mitigation strategies implemented, such as the construction of stilt houses and the development of silvofishery areas, have not been fully successful due to a lack of community involvement and weak oversight. Therefore, a more participatory, integrated, and sustainability-oriented approach is needed to improve environmental conditions while enhancing the socio-economic resilience of Muara Angke residents.

Abstract

The limited availability of teaching materials that support the development of critical thinking skills and scientific literacy in a contextual and reflective manner. Textbooks used in schools generally focus on memorizing concepts and do not encourage the exploration of complex socio-scientific issues. This, study aims to test the effectiveness of a science e-module containing Socio-Scientific Issues (SSI) with a Problem-Based Learning (PBL) model in improving critical thinking skills and scientific literacy of junior high school students. The study used a one-group pretest-posttest design as part of the assessment stage in the R&D Plomp model. The research subjects consisted of 44 eighth-grade students of SMP Negeri 2 Singaraja, who were selected purposively. Data were collected through a critical thinking skills test based on Ennis indicators and a science literacy test based on Vision III. The analysis results showed a significant increase in the posttest scores of critical thinking skills (N-Gain = 0.70) and science literacy (N-Gain = 0.58), with a high effect size value. Analysis per indicator showed the highest increase in the Situation and Reason indicators (critical thinking), as well as Critical Thinking and Acting (science literacy). The e-module also encouraged active student involvement in problem-based learning and contextual issues

Abstract

This study analyzes the porosity characteristics of Pliocene limestone from the Mundu Formation in the Gunung Pegat area, Lamongan, East Java, which lies within the Rembang Zone and is considered a potential carbonate reservoir. The research involved geological field mapping, measurement of four stratigraphic profiles, and collection of thirteen rock samples. Laboratory methods included petrographic analysis to classify lithofacies, core analysis to determine porosity, calcimetry for carbonate content, and microfossil analysis for age and depositional environment. Petrographic results show dominant packstone and wackestone lithologies, with pore types consisting of interparticle, moldic, and vuggy pores formed through bioclast dissolution and diagenesis. Core analysis reveals porosity values ranging from 1.5% to 22.1%, averaging 13.6%. High-porosity zones (>20%) occur in the western and northwestern parts, associated with bioclast-rich facies and meteoric water dissolution, whereas low values (<10%) are concentrated in the southeastern part due to compaction and recrystallization. These findings indicate that lithofacies variation and diagenetic processes significantly control reservoir quality. Overall, the Mundu Formation demonstrates good potential as a carbonate reservoir, particularly within packstone facies with well-developed secondary porosity, providing a useful basis for hydrocarbon and groundwater exploration in the northern East Java Basin.

Abstract

Palolo district in Sigi regency has great potential in developing maize production as part of efforts to realize regional food self-sufficiency. However, increasing maize production in this area faces various challenges, including land limitations, climate change, and access to technology and markets. The study aims to determine the potential for increasing maize production based on the support of internal and external factors in Palolo district, Sigi regency. Sampling was done with a purposive sampling technique where members were selected intentionally, namely on the potential for increasing corn production in Palolo District, by tracing the population sampled by as many as 26 sample corn farmers. The data analysis used is SWOT analysis. The results of the research show that the potential for increasing maize production in Palolo district is supported by internal factors, among others: the existence of human resources in maize farming, the existence of superior seeds from the government, the increase in maize production, the existence of fertilizer subsidies, spray assistance from the government, and the direction of extension workers to farmers. External factors, such as the development of agricultural technology, the local government's support for maize farming, the increasing market demand for food, the availability of affordable facilities and infrastructure, and farmers' understanding of maize farming, also support this potential.

Abstract

Approximately 40.42 % of the forest in the province of East Nusa Tenggara is a protected forest, 23.68 % production forest, conservation forest 19.37 %, 10.90 % limited production forest and 5.63 % is convertible forest. Its still needs better management to optimize outcomes from these resources.  Analysis of dry forest composition, calculation of carbon pools availability, carbon sequestration and its behavior in East Nusa Tenggara, Indonesia are carried out to achieve these objectives.  The result shows that a total of 2097 tree individuals, it’s representing 94 species, 72 genera and 45 families, were found in the research sites.  Eucalyptus urophylla were found to be the most dominant species in the research sites and Elattostachys verrucosa have potential to replace Dryobalanops aromatic. Most of family distribution models can describe the stand structure in research sites. And carbon stock of the living, litter and soil all decreased from virgin forest to the conventional logging ang reduced impact logging, carbon concentration of these biomass in the coffea agroforestry system were slightly higher than those of virgin forest and logging treatments (ranging 0 – 52 %). Carbon stock of the living and soil increased with a decreasing harvest and reached the highest stock in the coffea agroforestry.

Abstract

This study aimed to examine the effect of a Problem-Based Learning (PBL) model integrated with ethnoscience on students’ energy literacy and learning outcomes compared to conventional PBL. A quasi-experimental design was employed using a non-equivalent control group with pre-test and post-test. The population consisted of all 67 Grade X students at SMA Negeri Satu Atap Lembongan, who were divided into experimental and control classes based on their existing class groupings. The experimental group received instruction using the ethnoscience-integrated PBL model, while the control group was taught using standard PBL. Data were collected using validated instruments assessing energy literacy (knowledge, attitudes, and behavior) and cognitive learning outcomes. Results of analyzed using MANCOVA showed that the experimental group experienced significantly higher gains in both energy literacy (p < 0.05) and learning outcomes (p < 0.05) compared to the control group. The findings suggest that integrating ethnoscience into PBL provides contextual relevance and enhances the effectiveness of science instruction. This model can serve as a culturally responsive approach to improve students' scientific understanding and engagement.
