Abstract

Pada bulan Juni 2023 terjadi longsoran di ruas jalan Nasional Malinau – Tanjung selor yang menyebabkan badan jalan terputus. Apabila sudah terjadi longsor, maka diperlukan penanganan perkuatan lereng yang dapat berupa konstruksi dinding penahan tanah. Penelitian ini bertujuan untuk melakukan analisis  terhadap lereng yang sudah longsor guna menentukan tipe penanganan yang tepat.  Untuk mengetahui parameter tanah pada kondisi kritis (SF ≤ 1), digunakan analisis balik dengan bantuan program Plaxis 2D. Dari hasil perhitungan didapat nilai faktor keamanan pada kondisi awal sebelum terjadi longsor sebesar 1,507. Nilai tersebut diperoleh dengan memodelkan kondisi lereng dengan kontur asli dan nilai parameter tanah sesuai yang didapat pada saat penyelidikan tanah, yaitu kohesi (c) =17,29 Kn/M2 dan sudut geser ( θ)=20,20. Nilai faktor keamanan pada saat longsor sebesar 1,043 diperoleh dengan analisis balik (back analisis). Dimana nilai nilai parameter tanah sesuai hasil back analisis sebesar, kohesi (c) =12,64 Kn/M2 dan sudut geser ( θ)=3,00 . Factor keamanan lereng dengan menggunakan konstruksi bored pile kombinasi dengan geotextile sebesar sebesar 1,53

Abstract

This study investigated the impact of mobile phone–derived electromagnetic wave (EMW) exposure on the uterus and progeny of pregnant Balb/c mice. Fourteen pregnant mice were randomly assigned to two groups (n=7 each). The control group (CG) was not exposed to EMW. In contrast, the experimental group (EG) was subjected to continuous exposure to EMW at a whole-body specific absorption rate (SAR) of 1.74 W.kg-1 for 24 hours daily from gestational day (GD) 1 to 19. On GD 20, all mice were euthanized, and body weight, oxidative stress biomarkers, and uterine histological parameters were assessed. Maternal body weight at termination showed a significant reduction in EG compared with CG (p < 0.05). However, differences in overall body weight gain, malondialdehyde (MDA), and superoxide dismutase (SOD) levels were not statistically significant (p > 0.05). Histological evaluation revealed marked alterations: endometrial scores were significantly higher in EG (3.32) than in CG (0.56) (p < 0.05), and myometrial scores were elevated in EG (1.72) versus CG (0.64). Endometrial thickness was reduced in EG (0.748 mm) compared with CG (1.470 mm) (p < 0.05), whereas myometrial thickness showed no significant difference. Continuous EMW exposure (24 h.day-1, GD1–GD19; SAR 1.74 W.kg-1) was associated with lower maternal weight at GD20, reduced litter size, higher endometrial/myometrial injury scores, and reduced endometrial thickness, while MDA and SOD differences were not statistically significant (p > 0.05). These findings warrant further studies to clarify the mechanisms involved without overstating the changes in oxidative biomarkers.

Abstract

Background: Dengue Hemorrhagic Fever (DHF) is still a significant burden to global public health. Successful prevention is a function of community capacity, including locus of control (internal belief in one’s ability) and collective potential to implement prevention. Objectives: The objective of this research was to measure K, A and P with a specific emphasis on examining the degree to which these mentored K, A and P align with community sense-making (meaning), constructed capacity (function), and perceived controllability for making useable space free from vectors. Methods: A cross-sectional design was used, with 102 respondents (mainly women, productive age group and primary education level). Descriptive statistics, Chi-Square test for bivariate analysis and Multivariate Logistic Regression were used to determine independent predictors. Results: A noticeable gap between the KAP was determined. Although the proportion of respondents with favorable attitudes is high (66.7%), that of preventive practices was low (54.9% poor score). There was marginal knowledge (45.1% poor) with a high proportion of critical misconceptions (80.4% incorrect response to key transmission point). On multivariate analysis, significantly associated with good knowledge were education (Junior High vs Primary School) (OR=4.1, p=0.015) and middle income for favorable attitudes (OR=2.9, p=0.041). Notably, neither demographic variable (age, gender, education nor income) showed association with good preventive practice. Conclusion: The poor practice indicates a lack in the ability of DHF preventive activities, i.e. the capacity and collective control despite of high motivation (attitude). That practice was not also predicted by demographics implies that barriers are structural and environmental. Hence, interventions will need to move away from knowledge-based approaches to community mobilization for control and resource movement towards dismantling structural drivers for closing the attitude-practice gap.

Abstract

Background: HIV prevention in rural communities like Ngadas Village (Mount Bromo) faces two major challenges: stigma driven by misconceptions and the need for social resilience amid rapid social and economic transitions influenced by tourism. Limited access to health information and education increases the risk of myths, discrimination, and a poor sense of coherence. This salutogenic study explores how community coherence and cultural strength can serve as resources to reduce HIV stigma and promote resilience. Objective: This study aims to evaluate the level of HIV knowledge and stigma among residents of Ngadas Village and identify factors influencing them. Methods: A cross-sectional quantitative design was used, involving 102 residents who completed a structured questionnaire covering demographics, HIV knowledge, stigma, and attitudes. Data analysis employed chi-square tests and logistic regression (p<0.05) to determine significant predictors. Results: Most respondents (90.2%) were female, with 66.7% having primary education. Although 66.7% demonstrated good general knowledge, a significant gap in health literacy existed—94% misunderstood HIV transmission, wrongly believing it spread through sharing meals or cutlery. This misconception contributed to high stigma levels, with 49% exhibiting poor or high stigma. Higher education (Junior High OR: 10.9; Senior High OR: 7.4) and middle income (OR: 3.4) significantly predicted lower stigma. A more positive attitude was also associated with middle income (OR: 5.4). Conclusion: Misconceptions about casual HIV transmission are the primary source of stigma and barriers to social coherence. Targeted health literacy interventions, combined with economic empowerment and improved access to education, are essential to strengthen community resilience and reduce HIV-related stigma.

Abstract

Jalan poros utama di Desa Gurimbang yang menghubungkan Desa Gurimbang, Sukan Tengah, dan Tanjung Perangat mengalami longsor, mengakibatkan terganggunya akses transportasi darat dan berpotensi menghambat pasokan air bersih karena lokasi longsor berdekatan dengan intake Perumda Tirta Segah Unit Gurimbang. Diperlukan analisis geoteknik untuk menilai stabilitas lereng dan merancang perkuatan yang efektif. Oleh karena itu dilakukan penelitian ini untuk menganalisis penanganan longsor menggunakan perkuatan sheet pile dan dinding kantilever, mencakup stabilitas terhadap geser, guling, daya dukung tanah, serta stabilitas global. Tekanan tanah dihitung menggunakan teori Rankine, dengan analisis kapasitas dukung berdasarkan metode U.S. Army Corps untuk sheet pile dan teori Meyerhof serta Hansen untuk dinding kantilever. Analisis dilakukan pada empat model kondisi lereng, yaitu sebelum dan sesudah longsor dengan dua variasi muka air tanah (aktual dan penurunan 3 m), menggunakan metode Bishop dan Finite Element Method (FEM). Hasil menunjukkan faktor keamanan (SF) metode Bishop berturut-turut 1,411; 1,453; 1,517; dan 1,517, sedangkan metode FEM menghasilkan 1,408; 1,430; 1,509; dan 1,511. Karena SF < 1,5, lereng dinyatakan tidak stabil dan memerlukan perkuatan sepanjang 35 m. Analisis perkuatan menunjukkan sheet pile memiliki stabilitas geser 17,502; guling 5,29; daya dukung 5,269; dan SF global 1,568–1,534, sedangkan dinding kantilever menghasilkan 3,595; 4,268; 19,366; dan SF global 1,569–1,529. Perbandingan RAB menunjukkan biaya sheet pile Rp740.150.000,00 dan kantilever Rp604.442.285,33. Dengan demikian, perkuatan dinding kantilever dinilai lebih ekonomis dan menjadi solusi alternatif untuk penanganan longsor di lokasi tersebut.

Abstract

Background: Pregnant women often use mobile phones for communication and health-related information. The World Health Organization (WHO) recommends minimizing mobile phone use during pregnancy to reduce maternal and child health risks. Electromagnetic waves (EMW) from cell phones can be absorbed by the brain and may affect neuronal function.Objective: This study aimed to evaluate the size, histology, and number of Purkinje cells in the cerebellum of pregnant mice exposed to cell phone EMW compared to unexposed controls.Methods: Fourteen pregnant Balb/c mice were randomly divided into exposed (EG) and control (CG) groups. The EG was exposed to an electromagnetic wave with a specific absorption rate (SAR) of 1.74 W/kg for 24 hours per day from gestation day 0 to 19. On day 20, cerebellar tissues were harvested and processed with hematoxylin–eosin (HE) staining for histological assessment.Results: The mean Purkinje cell size in the EG (0.069 ± 0.009 mm) was slightly smaller than in the CG (0.070 ± 0.007 mm), but this difference was not statistically significant (p = 0.741). However, the Purkinje cell count was significantly lower in the EG (6.160 ± 0.746) than in the CG (7.800 ± 0.764; p < 0.001), indicating that EMW exposure reduced Purkinje cell numbers.Conclusion: Exposure to cell phone EMW during pregnancy led to a significant reduction in Purkinje cell numbers in the cerebellum, while cell size remained unchanged. These findings suggest that prenatal exposure to EMW may negatively affect fetal cerebellar development. This underscores the need for pregnant women to be cautious with mobile phone use and highlights the importance of further research to clarify the risks to maternal and fetal health.
