Abstract

Pneumonia is an illness that frequently affects young children and significantly influences their health and overall life quality, particularly in toddlers. This research seeks to explore how parental awareness and actions relate to the seriousness of pneumonia among toddlers at the Lingsar and Sigerongan Community Health Centers. This study is an observational analytic study with a cross-sectional research design using consecutive sampling. The study was conducted in the working area of the Lingsar and Sigerongan Community Health Centers, West Lombok with a research sample of 112 respondents. The information collected was examined using the Spearman's rho test. The findings indicated that a majority of the parents of toddlers were aged between 20 and 35 years (83.9%), were predominantly female (51.5%), had low levels of education (51.8%), and the majority worked as housewives (74.1%). The data also showed that there was a high level of knowledge (80.4%) and positive behavior (96.4%). The analysis of the knowledge and behavior data through the Spearman's rho test yielded results of (p = 0.807) and (p = 0.292), indicating no significant correlation between parental knowledge and behavior with the severity of pneumonia in toddlers (p > 0.05). Furthermore, there was no significant link found between the history of basic vaccinations, nutritional status, family smoking background, exclusive breastfeeding history, low birth weight history, prematurity, and environmental factors with the severity of pneumonia in toddlers. There was no association between parental knowledge and behavior and the severity of pneumonia in toddlers at the Lingsar and Sigerongan Health Centers in West Lombok.

Abstract

In an effort to understand the factors influencing healthy eating habits among adolescents, there remains a lack of research that comprehensively examines the relationship between nutritional knowledge and dietary patterns of junior high school students in Mataram City. This study aims to determine the relationship between the level of nutritional knowledge and dietary patterns of students at public junior high schools in Mataram City. This study utilized a quantitative framework featuring a descriptive correlational method and a purposive sampling strategy to gather data from 317 seventh-grade pupils across 10 schools in Mataram City. The data were evaluated using the Pearson correlation method and the Chi-Square analysis. The findings revealed a positive and significant link between students' nutritional knowledge and their eating patterns, though the correlation was weak (r = 0.178; p = 0.002). These results suggest that enhancing nutritional knowledge may lead to improved dietary habits, but environmental and social influences are also significant. Further investigation is necessary to gain a deeper understanding of this relationship and to explore how other factors might affect the link between nutritional knowledge and student eating behaviors in a more thorough manner.

Abstract

Indonesia’s tectonic setting makes coastal areas highly vulnerable to seismic hazards, including liquefaction. This study aims to analyze the liquefaction potential in Arang Beach, Labuhan Ijuk, Sumbawa, using the Horizontal to Vertical Spectral Ratio (HVSR) method. Microtremor data were collected at 70 measurement points and processed using Geopsy through windowing, filtering, and HVSR analysis to obtain dominant frequency (f₀) and amplification factor (A₀), followed by inversion to estimate shear wave velocity (Vₛ), sediment thickness (h), and Poisson’s ratio (σ). The results show that f₀ ranges from 0.294–17.542 Hz and A₀ from 0.928–15.914, with low-frequency and high-amplification zones concentrated in the southern–western area, indicating thick, soft sediments. Vₛ values (63.486–712.48 m/s) further confirm the presence of very soft to hard subsurface layers, with high liquefaction susceptibility associated with low Vₛ, high σ, and thick sediments. These findings indicate that the southern–western part of the study area has the highest seismic vulnerability and liquefaction potential. This study concludes that HVSR is effective for identifying site effects and liquefaction-prone zones. The results provide a scientific basis for seismic microzonation, coastal spatial planning, and the development of earthquake-resistant infrastructure in vulnerable coastal regions.

Abstract

Butterflies are important bioindicators and pollinators whose presence is strongly associated with the availability of food plants and habitat conditions. This study aimed to analyze the relationship between food plant diversity and butterfly diversity in Taman Wisata Alam Kerandangan, West Lombok. The research was conducted in three observation blocks, namely utilization, protection, and rehabilitation, using a survey method along transects. Data were collected on the diversity and abundance of food plants and butterflies, and analyzed using the Shannon-Wiener diversity index and Pearson Product Moment correlation. The results showed that food plants consisted of 1,298 individuals belonging to 27 species and 16 families, with an H’ value of 2.591; the dominant family was Rubiaceae, and the most abundant species was Clerodendrum paniculatum. Butterflies were recorded at 687 individuals, comprising 35 species and 3 families, with an H’ value of 3.183; the dominant family was Nymphalidae, and the most abundant species was Catopsilia pamona. The correlation analysis showed a very weak but positive relationship between food plant diversity and butterfly diversity (r = 0.028), while the relationship between food plant abundance and butterfly abundance was positive and very strong (r = 0.972). These findings indicate that butterfly occurrence in the study area is more strongly influenced by food plant abundance than by food plant diversity.

Abstract

Indonesia, recognized as a megabiodiversity country, harbors rich biological resources including fungi, which play vital ecological and economic roles. This study aims to analyze the diversity and distribution patterns of macrofungi in the Aikmel Resort area of Mount Rinjani National Park, Lombok. A descriptive–exploratory approach was conducted through field surveys using transect plots in two research stages. Data collection included species identification and measurement of environmental parameters such as temperature, light intensity, soil pH, and humidity. The results of the first stage recorded 40 species, while the second stage identified 37 species. After combining both datasets and removing duplicate species, a total of 68 unique macrofungal species were obtained, belonging to Basidiomycota, Ascomycota, and Mycetozoa. These species were distributed across various orders, families, and genera, with Agaricales and Polyporales as the dominant groups. Most macrofungi were found on decayed wood, indicating its importance as the primary substrate. Diversity analysis revealed a moderate level of diversity with relatively low dominance, fairly even species distribution, and high species richness. Environmental factors such as temperature, soil pH, light intensity, and humidity influenced the variation in macrofungal community structure between the two stages. In conclusion, the Aikmel Resort area exhibits high macrofungal diversity with dynamic community structure influenced by environmental conditions and substrate availability, highlighting its ecological importance as a reservoir of fungal biodiversity.
