Abstract

Coastal communities in Indonesia face limited access to clean water because water sources are dominated by seawater and the availability of fresh water is extremely limited. This problem creates a need for innovative and sustainable solutions that can be applied in everyday life and utilized in science learning. This study aims to design and test the feasibility of a solar panel–based seawater purifier as a contextual physics learning medium and a means of providing clean water for coastal communities. The research method used is Research and Development (R&D), conducted through the stages of needs analysis, design, prototyping, expert validation, and limited field trials. Data collected includes expert validation results, practicality assessments by teachers and students, and empirical measurements of water quality such as pH, TDS, salinity, specific gravity, ORP, and EC. Qualitative findings from the validators indicate that this tool has good functionality, is relevant for learning, is easy to use, and is safe to operate. The results show an average validity of 3.73 (very valid) and practicality of 3.60 from students and 3.86 from teachers (very practical category). Water quality tests showed a pH of 6.83, TDS of 124 ppm, which meets WHO standards (TDS < 500 ppm), salinity of 0.01%, specific gravity (SG) of 1.00, ORP of 224 mV, and EC of 0 µS/cm, indicating that the water is suitable for consumption. Thus, the aim of the research is to produce a valid, practical seawater purifier and provide a sustainable alternative solution for the clean water needs of coastal communities.

Abstract

This study aims to characterize potential gas-bearing reservoir zones in the FR Field within the Balikpapan Formation, Kutai Basin, through the integration of Amplitude Versus Offset (AVO) analysis and Fluid Replacement Modelling (FRM) using a single-well dataset. The Balikpapan Formation in the Kutai Basin is known for its complex stratigraphic and lithological heterogeneity, which poses challenges for seismic interpretation. The three-dimensional (3D) pre-stack seismic gathers were processed to preserve true amplitude for reliable AVO analysis. Intercept and gradient attributes were extracted to identify Class III AVO anomalies linked to gas-saturated sandstone. Validation was carried out using FRM based on well log data (Vp, Vs, and density) by simulating elastic property changes under different fluid conditions using Gassmann’s equation. The FRM results indicate a decrease in P-wave velocity and Poisson’s ratio under gas-saturated conditions, consistent with AVO responses. AVO attribute maps further depict the lateral distribution of zones prone to gas, offering valuable insights for well placement and field development strategies. The integration of AVO and FRM effectively reduces interpretation uncertainty and improves the understanding of reservoir characteristics within the Balikpapan Formation.

Abstract

Science literacy is an essential competency for primary school students to face 21st-century challenges. However, few assessment tools combine strong psychometric quality with cultural relevance. This study aimed to examine the psychometric properties of a local wisdom–based science literacy instrument for primary school students within the Item Response Theory (IRT) framework. The instrument comprised 34 multiple-choice items aligned with science literacy indicators and was administered to 300 fourth-grade students from several schools in Jember, Indonesia. Expert judgment ensured content validity, while empirical analyses using QUEST and R Studio evaluated item performance. The results showed good model fit, excellent reliability (0.97), and well-balanced item difficulty levels, confirming the instrument’s ability to measure a wide range of student abilities. Person–item maps and item characteristic curves indicated high discriminative power and measurement precision. Embedding local wisdom elements enhanced cultural authenticity and student engagement in science learning. Overall, the instrument demonstrated strong psychometric and contextual validity, offering a reliable tool for assessing science literacy in primary education. Its application can help teachers identify learning needs and design culturally responsive instruction. Future studies should extend validation to broader cultural contexts and refine items for students with lower ability levels.

Abstract

Dam construction offers substantial benefits to society, including the raw water supply. However, such projects also exert significant impacts on water quality and the surrounding ecosystems. This study aims to examine changes in water quality and their subsequent effects on the local ecosystem, as well as to propose appropriate mitigation strategies. The methodology employed includes the measurement of physico-chemical water parameters and biodiversity surveys. A case study was conducted at the Pamukkulu Dam by comparing water quality conditions at two sites (the upstream and downstream) before and after construction. The findings reveal a deterioration in water quality attributable to sediment accumulation, eutrophication, and alterations to natural habitats and local biodiversity within one year following impoundment. Notably, BOD levels downstream increased from 1.07 mg/L to 6.18 mg/L, while COD levels rose from 7.04 mg/L to 105.68 mg/L. Ammonia concentrations downstream increased from <0.001 mg/L to 1.09 mg/L, and total coliform counts escalated from 11 MPN/100 mL to 2,800 MPN/100 mL. Furthermore, oil and fat levels downstream rose from <0.02 mg/L to 0.19 mg/L, and MBAS levels increased from <0.01 mg/L to 0.01 mg/L. This study concludes that dam construction significantly affects water quality and ecosystems, particularly within the reservoir and downstream river areas.

Abstract

The application of the Mbolo Weki method in early education has significant potential in supporting early detection of Diabetes Mellitus (DM) in the community. This study used a quasi-experimental method in Bima Regency, West Nusa Tenggara, on a population at risk of diabetes mellitus. The study subjects consisted of 120 individuals aged 30 years and above who were selected through a cluster random sampling technique. Data collection instruments included a questionnaire and a digital blood sugar monitor, as well as a community participation observation sheet. Data were analyzed using descriptive tests, normality tests, paired t-tests, and chi-square tests to assess differences and relationships between variables. The results showed that the increase in blood sugar checking behavior was also significant, with the intervention group showing an increase from 20% to 72%, while the control group only experienced an increase from 18% to 30%. The significant reduction in participants with blood sugar values ≥ 200 mg/dl in the intervention group (from 25% to 13%) compared to the control group (from 23.30% to 21.7%) further strengthens the effectiveness of this method. Statistical analysis using the t-test and chi-square test showed a p-value < 0.001, indicating a significant relationship between the education received and behavior change.

Abstract

Community participation played an essential role in reducing household waste in Kupang City, where waste management had remained poor and piles of garbage were common along the streets. This study aimed to enhance community involvement in managing and reducing household waste. A descriptive method was applied, involving 72 households from housing complexes in Naimata and Penfui villages. Data was collected through interviews, observations, and community-based interventions such as Focus Group Discussions (FGD), education, and assistance from local leaders. The treatment significantly improved community participation: households with good waste management practices increased from 8 to 52, while those with poor management decreased from 64 to 20. The number of households utilizing waste rose from 22 to 62, and those processing organic waste into compost increased from 7 to 68. Organic waste generation dropped from 72 liters/day to 13 liters/day, and inorganic waste from 239 to 215 liters/day. The study concluded that community-based education and support effectively enhanced waste reduction behaviors, highlighting the need for continued government and community collaboration to sustain these practices.

Abstract

This research aims to estimate the probability distribution of 330 mL product demand at PT XYZ using Monte Carlo simulation to support risk-based production and inventory decisions. Monthly demand data for one year was used to form an empirical probability distribution, followed by random number generation using the Mixed Congruential Generator method and the execution of 100,000 simulation iterations. The simulation results show that demand has a wide range of uncertainty, with the 90th and 95th percentiles falling within the range of 7,000–7,800 units per month. Extreme demand risks were also identified, with the probability of demand exceeding 7,460 units reaching 22.4%. Based on these results, quantile-based safety stock calculations indicate an additional need of approximately 1,800 units to achieve a 90% service level. Validation using Kolmogorov–Smirnov and Chi-Square tests shows that the simulation distribution is consistent with the historical distribution, thus validating the model. Overall, this research produced an accurate and reliable probabilistic framework to support capacity planning, buffer inventory determination, and demand uncertainty risk mitigation at PT XYZ.
