Abstract

Intertidal biota consist of various invertebrate organisms that inhabit coastal aquatic environments and are highly responsive to fluctuations in water quality. Environmental changes induced by shrimp pond waste discharge can substantially influence the composition and diversity of intertidal biota communities. As a result, water quality serves as a critical determinant in maintaining the ecological balance and sustainability of coastal ecosystems. This study aims to analyze gastropod diversity within the intertidal zone near a shrimp pond waste discharge site and assess water quality based on the diversity index in Labuan Pandan, Sambelia Village, East Lombok. The research was conducted between June and November 2023, with data collected from five sampling stations located directly in front of the discharge site. A total of 40 gastropod species, classified into 32 genera and 22 families, were identified. The highest Diversity Index (H') was recorded at station 5 (2.503), whereas the lowest value was observed at station 2 (1.569). The highest Uniformity Index (e) was found at station 4 (0.947), while the lowest was at station 3 (0.811). The Dominance Index (D) was highest at station 2 (0.245) and lowest at station 5 (0.112). Sediment analysis across all stations revealed two predominant substrate types: loamy sand and sandy loam.

Abstract

Modern agriculture faces challenges such as declining soil quality and dependency on chemical fertilizers that harm the environment. Bokashi fertilizer, produced through the fermentation of organic materials, offers an eco-friendly solution to enhance soil fertility. This study aims to analyze the nitrogen (N), phosphorus (P), and potassium (K) content in various types of solid bokashi fertilizers made from agricultural and household waste. The research method involves an experimental approach to bokashi production, including raw material collection, mixing with EM4 (Effective Microorganism 4) solution, and fermentation for three months. After production, chemical analysis was conducted in the laboratory to measure the NPK content. The results indicate variations in N, P, and K content, with straw showing a total nitrogen content of 2.17%, potassium at 2.65%, and phosphorus at 2.43%. The highest nitrogen content was found in peanut waste (2.42%), while the lowest was in household waste (1.08%). This study demonstrates that bokashi fertilizer can be an effective and environmentally friendly alternative. Future research recommendations include exploring factors affecting nutrient content and optimizing application methods for bokashi.

Abstract

Refractive errors occur when light entering the eye cannot be properly focused, resulting in blurry or unclear vision. This study aims to determine the relationship between reading distance, reading duration, and smartphone usage duration with the incidence of refractive errors among students at SMAN 1 Praya. Using a cross-sectional design, this quantitative study involved 103 respondents selected through stratified random sampling. Data were analyzed using univariate and bivariate methods with the Chi-square test. The results showed significant relationships between reading distance (p-value = 0.001), reading duration (p-value = 0.001), and smartphone usage duration (p-value = 0.001) with the incidence of refractive errors. In conclusion, reading distance, reading duration, and smartphone usage duration are significantly associated with the incidence of refractive errors among students at SMAN 1 Praya. This research can be expanded by incorporating additional independent variables, such as outdoor activities, sleep patterns, or genetic factors, to offer a more thorough understanding of the risk factors for refractive errors.

Abstract

NCIT has several advantages, such as quick measurement time, no need for contact between the device and the patient, and greater comfort for patients compared to measuring temperature using TDA or rectal digital thermometers. These advantages make NCIT suitable for use in PKM. However, previous research on the comparability of NCIT measurement results with TDA in neonates is limited and shows varying results. This study aims to determine the agreement of NCIT measurement results with TDA measurement results in neonates. The study is an analytical observational study with a cross-sectional design. 25 neonates participated in this study, with some having their temperature measured only once and others more than once, according to an agreement with their guardians. A total of 62 temperature measurement samples were taken after going through the inclusion and exclusion process. The measuring instrument used was the digital axillary thermometer (TDA), which served as the reference. Additionally, three types of non-contact infrared thermometers (NCITs) were used to assess their agreement for this study. The sample data was analyzed using the One-Sample T-test, Intraclass Correlation Coefficient (ICC) method, and Bland Altman Plot. The ICC results indicated poor agreement of each NCIT with the TDA. The One Sample T-test indicates that of of the NCIT used does not have statistically significant differences compared to TDA, whereas two other types of NCIT do have statistically significant differences compared to TDA, The Bland Altman Plot analysis shows that the Limits of Agreement for each type of NCIT with TDA are still wide. From these results, it is concluded that these three types of NCIT cannot replace TDA as a body temperature measurement tool for neonates.

Abstract

Insect diversity in agricultural ecosystems is influenced by cropping patterns and physical environmental conditions. In cabbage cultivation, it is crucial to understand cropping management to support the sustainability of agricultural ecosystems. This study aims to examine the effects of cropping patterns and environmental factors on insect diversity and evaluate the effectiveness of sticky traps in cabbage fields. Monoculture and polyculture systems (a combination of cabbage and lettuce) were tested to assess differences in insect community structure based on diversity, abundance, evenness, similarity, and dominance. The study was conducted from July to August 2019 using sticky traps in yellow, green, and white colors. The analysis included the Shannon-Wiener diversity index (H'), evenness (e), dominance (D), species richness, and Sorensen and t-Hutcheson tests. Environmental factors such as temperature and humidity were also analyzed to assess their impact on insect community structure. The results showed no significant differences in insect community structure between monoculture and polyculture systems, with the Aleyrodidae family dominating both systems. Temperature and humidity significantly influenced the insect community. Yellow sticky traps were found to be the most effective in capturing insects compared to green and white traps.
