Abstract

The North East Java Basin is one of the prospective hydrocarbon areas in Indonesia with the Kujung and Ngimbang Formations as the main intervals of the petroleum system. This study aims to identify the mechanism of overpressure formation and reservoir potential based on well log data analysis. The methods used include interpretation of Gamma Ray (GR), Resistivity (ILD), Neutron porosity (NPHI), and Bulk Density (RHOB) logs, as well as pore pressure estimation using the Eaton method. The analysis results indicate that the Kujung Formation has two prospective zones at depths of 4200–4800 ft and 7500–8500 ft indicating a gas-bearing carbonate reservoir, while the Ngimbang Formation is dominated by shale and dense carbonate that function as cap and source rocks. The beginning of the overpressure zone was detected at a depth of approximately 4400 ft, characterized by anomalies in the NPHI, RHOB, and Δt logs indicating undercompaction. Dutta crossplot analysis (DT–RHOB) confirmed the dominance of smectite minerals indicating that the overpressure was formed due to a loading mechanism. Thus, the Kujung Formation acts as a porous reservoir zone, while the Ngimbang Formation functions as a cap rock in the North East Java Basin petroleum system.

Abstract

Indonesia is the world’s largest producer of palm oil, a strategic commodity that significantly underpins the national economy and serves as the main source of income for millions of smallholder farmers. While oil palm cultivation is often associated with high and relatively stable financial returns, providing a vital pathway out of poverty, the actual financial dependence of farming households on this single source of income remains a critical subject of inquiry. This study aims to analyze the, contribution of oil palm farming to fulfilling household needs of farmers in Pante Ceureumen Sub-district, West Aceh Regency. The research employed a purposive sampling method with 100 oil palm farmer respondents. Data were analyzed by calculating the ratio between farming income and total household expenditures. The results indicated that the average income from oil palm farming was IDR 74.003.15 per year, while the average household expenditure was IDR 52.269.00 per year. The contribution of oil palm farming to farmers' household expenditures reached 142 %, signifying that the income derived from oil palms not only covered all household necessities but also yielded a surplus of 42%. This finding demonstrates that oil palm farming plays a vital role in enhancing the welfare of farmer households in the study area.

Abstract

This study aims to analyze the effectiveness of the RADEC (Read, Answer, Discuss, Explain, Create) learning model in improving students’ literacy and critical thinking skills in geography learning at the senior high school level. The need for this research arises from the consistently low literacy and higher-order thinking performance of Indonesian students in PISA and AKM, as well as the limited implementation of RADEC in geography. This study employed a one-group pretest–posttest quasi-experimental design involving 16 eleventh-grade students from SMA Negeri 3 Tebing Tinggi Barat, Riau Province. The instruments consisted of a literacy test based on AKM indicators and a critical thinking test adapted from Facione’s framework, which measured Interpretation, Analysis, and Evaluation. Data were analyzed using descriptive statistics, N-gain calculations, and paired-samples t-tests. The results showed a significant improvement (p < 0.05) in both variables, with N-gain scores of 0.40 for geographic literacy and 0.36 for critical thinking, categorized as moderate. These findings indicate that the RADEC model enhances students’ literacy and critical thinking through structured stages involving reading comprehension, answering tasks, collaborative discussion, explanation, and the creation of learning products. The study provides empirical evidence for the application of RADEC in geography learning and highlights its relevance to the Merdeka Curriculum.

Abstract

Stunting has been a prevalent health issue in Indonesia, and Aceh Province is not exempt from this challenge. This situation has placed a substantial responsibility on all stakeholders to collaboratively work towards reducing stunting cases in Aceh. This study aimed to investigate the risk factors associated with stunting in both the highland and lowland areas of Pidie Regency. This study employed an analytical observational design with a cross-sectional approach. The instrument used was a questionnaire, a total sampling technique was applied to survey 30 mothers with children under 2 years old in Tangse Sub-district and other 30 mothers in Mutiara Sub-district. In the highlands, specifically Tangse Sub-district, four predictors were identified as significant contributors to stunting, namely socio-economics (p value: 0.013), parents’ educational background (p value: 0.036), pregnancy checks (p value: 0.005), and nutritional intake (p value: 0.011). On the other hand, in a lowland area, in Mutiara Sub-district, additionally, parenting patterns (p value: 0.002) and exclusive breastfeeding (p value: 0.001) were identified as two other significant predictors of stunting in this region.The analysis leads to the conclusion that stunting prevalence was higher in the highlands of Tangse Sub-district (60%) compared to in the lowlands of Mutiara Sub-district(20%).

Abstract

The Celukan Bawang (CFSPP) in Buleleng, Bali, utilizes coal as its primary fuel source, potentially impacting surrounding air quality and public health. This study aimed to analyze the concentrations of fine and coarse particulate matter (PM₂․₅ and PM₁₀) and to assess their environmental and health implications based on temporal and meteorological variations. The research was conducted from September to October 2025 using a quantitative descriptive method. Air quality measurements were taken at three sampling locations SP1 (east), SP2 (west), and SP3 (south) using an Air Quality Detector equipped with an optical light-scattering sensor and GPS. Data were analyzed using Microsoft Excel and compared to Indonesia’s ambient air quality standards (Government Regulation No. 22 of 2021). The results showed that PM₂․₅ concentrations ranged from 12.5–22.3 µg/m³ and PM₁₀ from 8.0–11.0 µg/m³, all below national thresholds (55 µg/m³ for PM₂․₅; 75 µg/m³ for PM₁₀). However, according to WHO (2021), guidelines, the PM₂․₅ value at SP1 (22.3 µg/m³) exceeded the daily exposure limit (15 µg/m³), indicating potential long-term risks such as respiratory and cardiovascular diseases. Overall, the air quality around CFSPP remains within national safety limits, although continuous monitoring and emission control are recommended to safeguard community health in downwind areas.

Abstract

This study aims to determine the effect of photosynthetic bacteria on the growth and productivity of corn (Zea mays L.) variety Pioneer 32. The study was conducted at the Experimental Field of the Faculty of Agriculture, Mulawarman University, Samarinda, in January–April 2025. The study used a Completely Randomized Design (CRD) with five treatments of photosynthetic bacteria concentration: P ₀ = 0 ml/L (control), P ₁ = 10 ml/L, P ₂ = 20 ml/L, P ₃ = 30 ml/L, and P ₄ = 40 ml/L, each repeated three times. The parameters observed included plant height, stem diameter, leaf area, cob weight, and grain yield per hectare. Data were analyzed using analysis of variance (ANOVA) at a significance level of 5%. The results showed that the administration of photosynthetic bacteria significantly affected the growth and productivity of corn plants. The P ₂ treatment (20 ml/L) provided the best results with a 15% increase in plant height and 20% increase in grain yield compared to the control. Higher concentrations (P₃ and P₄) did not provide significant increases. Thus, photosynthetic bacteria have the potential to be used as an efficient alternative biofertilizer to increase corn productivity sustainably.

Abstract

Padang City, located on the west coast of Sumatra Island, is one of the Region most vulnerable to tsunami disasters due to its position along the subduction zone between the Indo-Australian and Eurasian plates. This study aims to determine the effectiveness of using E-Comics as a learning medium for tsunami disaster mitigation at SMA 1 Pertiwi Padang City. The research employed a quasi-experimental method with a Non-Equivalent Group Design, involving two groups: the experimental class (XI IPS 2) using E-Comics and the control class (XI IPS 1) using conventional textbooks. Data were collected through questionnaires and documentation, and analyzed using normality, homogeneity, and t-tests with the aid of SPSS version 22.0. The results showed that the data were normally distributed and homogeneous, and there was a significant difference between the learning outcomes of the experimental and control classes, with a significance value of 0.95 > 0.05 and a t-value of 7.45. The average pre-test and post-test scores in the experimental class increased from 53.40 to 87.10, while the control class increased from 51.87 to 61.53. These findings indicate that using E-Comics effectively enhances students’ understanding and motivation in learning tsunami disaster mitigation material. Therefore, E-Comics can serve as an innovative alternative in geography learning, particularly in disaster-prone areas, to improve students’ literacy and preparedness for disasters.

Abstract

This study aims to identify the empirical needs for developing an Ethno-STEM-based and differentiated physics module to improve critical thinking skills among high school students in South Sumatra, within the context of global warming. A mixed-methods exploratory sequential design was employed, with qualitative data from open-ended questions informing the development of a quantitative Likert-scale questionnaire administered to 81 physics teachers and 1,118 Grade 10 students across five vulnerable districts. Results show that while 100% of teachers express interest in Ethno-STEM, only 24.7% have implemented it, primarily due to the lack of ready-to-use modules (32.4%) and curriculum time constraints (27.0%). Students exhibit diverse learning preferences, with 74.6% favoring hands-on experiments. Furthermore, 83.5% demonstrate analytical skills by identifying causes of environmental problems, but only 61% can compare solutions effectively. These findings reveal a significant gap between awareness and practice, underscoring the urgent need for contextual, culturally responsive, and differentiated learning materials. The study provides a strong empirical foundation for designing a project-based physics module aligned with the Merdeka Curriculum, integrating local wisdom, STEM principles, and learning style differentiation to enhance critical thinking.
