Abstract

Urine erythrocyte examination is one of the important parameters in urinalysis to detect hematuria and abnormalities of the urinary system. Delays in examination often become a challenge in laboratories, as erythrocytes are prone to lysis or morphological changes that may affect result accuracy. This study aimed to determine the effectiveness of Neutral Buffered Formalin (NBF) as a fixative in maintaining the count and morphology of urine erythrocytes at different examination delay times: 0 hours as control, and delays of 3 hours and 6 hours. Urine samples were collected using purposive sampling, and erythrocyte sediment examination was performed using a light microscope. Data analysis employed the Dependent Sample T-Test to compare results across each delay interval. The findings showed that the use of NBF was able to maintain the stability of urine erythrocytes up to a 6-hour delay, with differences in count and morphology that were not statistically significant (p > 0.05). These results indicate that NBF is effective as a fixative to preserve the quality of urine erythrocyte examination despite delays in analysis.

Abstract

Microscopic examination of fecal specimens using the flotation method has higher sensitivity than direct smear and sedimentation methods. Centrifugal flotation enables the detection of a greater number of helminth eggs and reduces the likelihood of false-negative results by facilitating the rapid sedimentation of interfering particles. The use of a saturated sucrose solution also provides a cleaner and clearer microscopic background. This study was conducted using fecal specimens containing Ascaris lumbricoides eggs to determine the optimal flotation time for recovering the highest number of eggs. Three positive fecal specimens were examined using centrifugal flotation with flotation times of 20, 30, and 40 minutes, each performed in five replicates. The recovered flotation layer was examined microscopically, and the number of Ascaris lumbricoides eggs was counted and averaged. Data were analyzed using the Shapiro–Wilk normality test followed by a one-way analysis of variance (One-Way ANOVA). The mean egg counts were 118 eggs at 20 minutes, 162 eggs at 30 minutes, and 134 eggs at 40 minutes of flotation. The One-Way ANOVA revealed a statistically significant difference among the flotation times (p = 0.000, α = 0.05). Variations in flotation time using the centrifugal flotation method significantly affected the number of Ascaris lumbricoides eggs recovered. Therefore, laboratory personnel are recommended to use a flotation time of 30 minutes with saturated sucrose solution when performing the centrifugal flotation method to achieve optimal egg recovery.

Abstract

Posyandu services are a form of community health effort that requires an accurate, fast, and structured data recording process. However, in many Posyandu, recording is still done manually, leading to problems such as data loss, delayed reporting, and difficulty monitoring the health development of toddlers and adolescents. This study aims to design an Android application for recording and tracking the history of integrated Posyandu activities to help cadres (kader) manage service data, including weighing, measurement, immunization, and other activity records. The application was designed using a system development method and equipped with data input features, digital storage, and automatic report generation. The results of this study are expected to improve the work efficiency of cadres, minimize recording errors, and support more accurate, integrated, and user-friendly community health monitoring at the Posyandu level.

Abstract

Hypertension remains a major contributor to cardiovascular morbidity, yet community screening often relies on late or opportunistic measurements. This study compares Logistic Regression, Random Forest, Gradient Boosting, XGBoost, and Support Vector Machine for hypertension risk prediction using a public dataset of 1,985 patient records and ten demographic, clinical, and lifestyle predictors. Numerical features were standardized, categorical features were one-hot encoded, and missing medication values were imputed using the mode. Models were evaluated using an 80:20 stratified train-test split and 5-fold cross-validation. The best model was optimized with RandomizedSearchCV and examined through feature importance and ablation study. Tuned Gradient Boosting achieved the highest cross-validation F1-score of 0.9994 and ROC-AUC of 1.0000. On 397 test records, it obtained 0.9975 accuracy, 1.0000 precision, 0.9951 recall, 0.9976 F1-score, and 1.0000 ROC-AUC, with only one false negative. Ablation showed that removing blood pressure history reduced test F1-score to 0.7681, confirming its dominant contribution. The model is promising for screening support, but external clinical validation is required before diagnostic use.

Abstract

Technological advancements have ushered the world into the Society 5.0 era—a human-centric societal concept that balances economic progress with the resolution of social issues through the integration of cyberspace and physical space. A crucial aspect of this digital transformation is product digitalization, which encompasses the processes of creating, modifying, or distributing products and services using digital technologies. The 10 Ulu Urban Village in Palembang City, as part of the urban ecosystem, features unique MSMEs (Micro, Small, and Medium Enterprises) that are often based on local or traditional products. This research is highly urgent because MSMEs in 10 Ulu urgently need to adapt quickly to the demands of the Society 5.0 era; however, there is a knowledge gap regarding the specific mechanisms by which product digitalization effectively strengthens their local competitiveness. The objective of this research is to conduct an in-depth analysis and measure the causal impact of product digitalization on various dimensions of MSME competitiveness, as well as to identify the factors that hinder or facilitate this process. The targeted output for this research is a publication in a SINTA-4 accredited journal. Keywords: MSMEs, Digitalization, Competitiveness, Society 5.0 Era, Products

Abstract

The management of correspondence archives in higher education institutions continues to face various challenges, including dependence on physical document storage, limited archival space, and difficulties in information retrieval. These conditions highlight the need for an archival management system capable of supporting document digitalization while facilitating archive classification and retrieval processes. This study develops a digital archive system based on Optical Character Recognition (OCR) and a Rule-Based System for the rectorate unit of Universitas Prabumulih. System development was conducted using the Design Thinking approach, which consists of the empathize, define, ideate, prototype, and test stages to ensure that the proposed solution aligns with user needs. OCR technology was utilized to extract textual information from scanned documents, while the Rule-Based System was implemented to identify and classify archives according to predefined rules. The developed system provides a more structured archival management mechanism through document digitalization, automated classification, and content-based document retrieval. The integration of these technologies enhances the efficiency of incoming and outgoing correspondence management and supports the transformation of archival practices from physical media to digital archives that are more accessible, manageable, and sustainable.

Abstract

The American cockroach, Periplaneta americana, is a pest that can potentially contaminate food and the environment, making its control important in environmental health. The use of plant-based materials with repellent activity may provide an approach to cockroach control. This study aimed to analyze and compare the effectiveness of kaffir lime (Citrus hystrix) and Indonesian bay leaf (Syzygium polyanthum) powders as natural repellents against P. americana. A true experimental study with a post-test only control group design was conducted. Powders of both leaves were tested at doses of 7, 9, and 11 g, with a 0 g control, using six replicates and 10 cockroaches in each experimental unit. Repellent responses were observed for one hour. Active-treatment data were analyzed using two-way ANOVA followed by Tukey's HSD test at α=0.05. The mean repellent responses of C. hystrix at 7, 9, and 11 g were 7.17, 7.67, and 9.17 cockroaches, respectively, compared with 5.00, 6.00, and 6.50 cockroaches for S. polyanthum. Plant powder type (F=51.735; p<0.001) and dose (F=11.327; p<0.001) significantly affected the repellent response, whereas their interaction was not significant (p=0.410). Tukey's HSD test showed a significant difference between the 7 and 11 g doses (p=0.015). C. hystrix powder produced a higher repellent response than S. polyanthum, with the highest response observed at 11 g. Both plant materials have potential for development as botanical repellents against P. americana.
