Abstract

Exclusive breastfeeding provides all the nutritional needs necessary for optimal growth during the first six months of life. The percentage of exclusive breastfeeding in the working area of the Montasik Health Center is only 30.5%. The purpose of this study is to determine the determinants of exclusive breastfeeding for babies in the working area of the Montasik Health Center, Aceh Besar Regency in 2025. This study uses an analytical descriptive design with a cross-sectional approach. A sample of 82 mothers with babies was selected through cluster sampling techniques in Mukim Bukit Baro. Data were collected through interviews using questionnaires and analyzed univariate, bivariate, and multivariate using SPSS 24.0. The results showed that only 30.5% of mothers gave exclusive breastfeeding. Most of the respondents had poor knowledge (57.3%), less family roles (52.4%), less supportive maternal behavior (48.8%), did not participate in the Breast Milk Echo (67.1%), had a low income (73.2%), and a small part worked (19.5%). Bivariate analysis showed a significant relationship between family roles (p=0.048), maternal behavior (p=0.013), and income (p=0.000) with exclusive breastfeeding. However, there was no significant relationship with the knowledge, participation of Gema ASI, and maternal work. Multivariate analysis showed only income had a significant effect (p=0.001; OR=8.479), indicating that mothers with sufficient income are 8.479 times more likely to give exclusive breastfeeding. In conclusion, income is the most powerful factor in exclusive breastfeeding. It is recommended that health workers improve education through various media and posyandu activities, and mothers are expected to increase knowledge, positive behavior, family involvement, and participation in the Gema ASI program.

Abstract

The Air Sebakul Landfill (TPA Air Sebakul) in Bengkulu City is facing significant environmental pressure due to increasing waste volume and suboptimal management methods. This study aims to analyze the types of environmental pollution caused by activities at the landfill and to explore household waste management based on biogas technology. Literature review shows that the open dumping system leads to water, air, and soil pollution. Leachate from waste contaminates groundwater sources, while greenhouse gas emissions worsen air quality and impact public health. Moreover, soil quality declines due to the accumulation of hazardous substances. On the other hand, organic household waste, which makes up the majority of the city’s waste composition, has high potential to be utilized as a raw material for biogas production. Biogas technology at household scale can offer a sustainable waste management solution, reducing landfill pressure while generating energy and organic fertilizer. The successful implementation of this management system requires synergy among government, community, and related institutions in the form of policies, education, and technical support to realize an environmentally friendly and sustainable waste management system in Bengkulu City.

Abstract

The increasing urgency to monitor and mitigate environmental pollution has driven significant interest in the development of advanced sensing technologies. Nanotechnology presents promising solutions through the application of nanoscale materials, among which maghemite nanoparticles (γ-Fe2O3) have garnered considerable attention due to their unique physicochemical properties, high chemical stability, a large specific surface area, and superparamagnetic behavior, making them suitable for separation, target deployment, and sensor regeneration. It functionalized maghemite nanoparticles to enhance their selectivity toward specific pollutants, including heavy metals ( e.g., Pb2+ and Cd2+) and toxic gases (e.g., NO, NH3, and H2S). These articles present a review of the structural and physicochemical characteristics of maghemite nanoparticles, including commonly applied synthesis methods, sensor mechanism, and their applications in pollutant detection, such as heavy metals and toxic gases. The review also highlights current challenges and outlines future directions for the development of more efficient, affordable, and sustainable maghemite-based sensors for next-generation environmental monitoring systems.

Abstract

Selectively producing 5-hydroxymethylfurfural (HMF) from biomass-derived carbohydrates is key in valorizing renewable resources into biobased chemicals and fuels. HMF is a crucial bio-based platform chemical, but its selective production from glucose and fructose remains challenging due to side reactions and product degradation. Modified niobium(V) oxide (Nb2O5) catalysts have shown great promise owing to their intrinsic Brøntsted and Lewis acidity, thermal stability, and surface tunability. This review overviews recent advances in catalyst design, including metal doping, structural tuning, and hybridization with porous materials. These have significantly improved HMF yields -up to 80%- while enhancing catalyst selectivity and reusability. A systematic review with a descriptive-analytical approach was applied, analyzing literature from 2015 to 2025 across major scientific databases. Furthermore, challenges, including side-product formation and active site leaching, are highlighted alongside future perspectives for scalable and green HMF synthesis using Nb-based catalysts. This review aims to guide the rational development of modified Nb2O5 catalysts for efficient biomass transformation. These developments are crucial for advancing Nb-based catalytic platforms and unlocking the full potential of HMF in a circular, bio-based chemical industry.

Abstract

Diabetes is a chronic disease that continues to rise globally each year, requiring early detection for more effective prevention. This study develops an artificial intelligence-based decision support system for diabetes prediction using a Hybrid XGBoost-SVM model. The model combines the Support Vector Machine (SVM), known for its interpretability, with XGBoost (XGB), which enhances accuracy through boosting techniques. The study utilizes the Pima Indians Diabetes Dataset, undergoing preprocessing, normalization, data splitting, and model training. The evaluation compares accuracy, precision, recall, and F1-score across the three models. Experimental results indicate that XGBoost and SVM both achieve an accuracy of 75%. However, the Hybrid XGBoost-SVM model provides consistently improved performance, achieving the highest accuracy (77%), along with increased precision (70%) and F1-score (65%). Although the numerical improvement in accuracy appears relatively small, this enhancement is significant in the medical context, especially due to improved precision and balanced classification. This study concludes that the Hybrid XGBoost-SVM approach offers a more optimal and reliable alternative in decision support systems for diabetes prediction. Future research can explore other model combinations, such as Stacking or Weighted Voting, to enhance predictive performance further.

Abstract

This study aims to analyze the response of a high-rise building to horizontal and vertical structural irregularities in a multi-story structure. The subject of the study is the Rahmah Mosque Tower, located at Jl. Lilawangsa, Gampong Paya Bujuk Tunong, Langsa Baro District, Langsa City, Aceh. This tower exhibits both horizontal and vertical irregularities, which can influence its behavior under applied lateral and vertical loadsThe structural behavior is evaluated by examining the building’s response to horizontal and vertical irregularities effect induced by seismic loading. The method for seismic loads are analyzed using dynamic response spectrum analysis in accordance with SNI 1726:2019, implemented in ETABS v18.1.1. Results indicate that failure in the Rahmah Mosque Tower is governed by beam collapse due to insufficient flexural capacity under seismic forces, whereas the columns are adequate to resist earthquake loads. Horizontally, the tower exhibits Type 1b and Type 1a irregularities, as well as Horizontal-Torsional Irregularity. Type 1a. Vertically, it displays Mass (weight) Irregularity and Vertical Geometric Irregularity. These irregularities could significantly affect a building's safety, stability, and structural efficiency. Designs that fail to calculate these irregularities may pose serious risks of damage, both under static and dynamic conditions.

Abstract

Anaemia in pregnancy constitutes a significant global public health issue, influenced by various risk factors such as maternal age and nutritional status. Nutritional issues during pregnancy impacts maternal and fetal health, necessitating careful consideration. An insufficient diet in the antenatal period can predispose to maternal malnutrition, subsequently affecting anaemia. The research was conducted to explore the correlation between nutritional status with anaemia’s prevalence among women in pregnancy at the Abepura Primary Care Facility. This research uses a cross-sectional approach with a descriptive correlational design. Conducted at Abepura Health Centre. The study population comprised all pregnant women who visited the Abepura Health Centre in 2022, totalling 714, with a sample size of 258. Sampling methodology utilising simple random sampling. Data acquisition through questionnaires derived from cohort studies of pregnant women. The chi-square test yielded a p-value of 0.041, indicating statistical significance at the 0.05 level. This finding suggests a meaningful association maternal nutritional well-being and anaemia’s prevalence at the Abepura Health Centre. The odds ratio obtained is OR 1.672 (CI 95% 1.020-2.742), indicating that pregnant women with poor nutritional status are 1.672 times more at risk of anaemia compared to those with adequate nutritional status. Enhance health service initiatives for pregnant women, particularly for those with anaemia, and closely monitor maternal nutritional well-being to promptly address any cases of malnutrition.
