Abstract

The aim of this research is to know the influence of anti mosquito electric gas that consisted Allethrin to the weight and colour of the rats liver. This research used an experimental method with the post test only  control group design.  The subject of this research is male rats weight of 150 grams each and total there was 24 rats that were divided to 4 groups. The first one, the  control groups (PO) was not given any of the gas, the second one, group 1 (P1) was given the gas for 4 hours everday, the third one, group  2 (P2), was given for 6 hours and last, group 3  (P3) was given 8 hours everyday. After later, on  30 Th day, the rats were terminated and being put in a surgery to remove their liver. This data was analyzed using SPPS for windows version 16. To see the differences in weight between the groups, it was analyzed using anova, and  to obtain the discoloration of the rats liver was analyzed using Kruskal Wallis Test. From the statistic tests, it show that there is significant difference in weight and color of liver in the group that α ≤ 0,05. According Anova Test, it shows that there is a significant difference α = 0,034 and from Kruskal Wallis test α = 0,013. In the conclusion anti mosquito electric gas that consist Allethrin affects the weight and the color of rats liver.

Abstract

The prevalence of refractive error and its relationship with education, age and sex at DR. Wahidin Soedirohusodo general hospital have not been comprehensively assessed. The aim of this study was to examined the distribution and risk factor of refractive errors at DR. Wahidin Soedirohusodo general hospital. Methods of this study used population based cross-sectional study. Respondents were interviewed and underwent standardised clinical eye examinations. Refractive error was determined by an automatic refraction device. Refractive errors are myopia, hyperopia and astigmatism. Myopia and hyperopia were defined as spherical equivalent of -0.50/+0.50 diopter (D) or worse, respectively; astigmatism was defined as cylindrical error >0.50 D. Total of 1760 patients with refractive error from January 2016 to January 2018 with 700 or 39,8% males and 1060 or 60.2% females. Based on the cross-tabulation output, it is known that the respondents with the most elementary level of education experienced mild hypermetropy (10.2%), the junior high school education experienced mild myopia (6.8%), high school and bachelor education experienced mild myopia (8%). Age 6-15 years experienced the most myopia compositus astigmatism (5.7%), 16-25 years mild myopia (10.2%), 26-35 years mild myopia (4.5%), 36-45 years mild myopia (10.2%), 46-55 years mild hypermetropia (10.2%) and 56-65 years mild hypermetropia (5.7%). Kruskal Wallis test it is known that the sig value obtained = 0,000 indicates that there are differences in refractive abnormalities based on education and age. Chi square sig value obtained is 0.021, indicating that there is a relationship between sex and refractive errors. Multivariate analysis revealed female subjects inhibited the risk of mild myopic by 0.157 times the male subjects and simple myopia astigmatism by 0.082 times the male subjects. The relationship of myopia, astigmatism and hypermetropia with age and education is not significant. The risk factor of mild myopia and simple myopia astigmatism decrease in female than male. These findings may help clinicians to better understand the patterns of refractive error and planning for preschool vision-screening programs.

Abstract

Pregnant women's health is an important aspect of the public health system, where grouping disease data can help in risk identification and better treatment planning. However, traditional clustering methods such as K-Means often face challenges in optimal separation between clusters, especially when the attributes used are irrelevant. This study aims to optimize the K-Means method in disease clustering in pregnant women by applying Random Forest-based attribute selection. Of the six available attributes (age, weight, height, gestational age, systole, and diastole), the three main attributes namely systole, diastole, and gestational age were selected based on the Importance Score from Random Forest. The test results showed that the use of these three attributes increased the Silhouette Score by 0.21 (from 0.23 to 0.44), indicating better cluster separation, and lowered the Davies-Bouldin Index by 0.69 (from 1.50 to 0.81), indicating a more compact and well-separated cluster. Clustering visualization using Principal Component Analysis (PCA) supports these results. In addition, the calculation of the Elbow method shows the optimal number of clusters at k=3, reinforcing the conclusion that the selection of the right attributes and the number of clusters improves the quality of clustering. Overall, this study proves that the selection of Random Forest-based features is able to optimize the K-Means method in disease clustering in pregnant women, which is expected to improve the effectiveness of diagnosis and treatment planning.Kesehatan ibu hamil merupakan aspek penting dalam sistem kesehatan masyarakat, di mana pengelompokan data penyakit dapat membantu dalam identifikasi risiko dan perencanaan perawatan yang lebih baik. Namun, metode clustering tradisional seperti K-Means sering kali menghadapi tantangan dalam pemisahan yang optimal antar cluster, terutama ketika atribut yang digunakan tidak relevan. Penelitian ini bertujuan untuk mengoptimalkan metode K-Means dalam clustering penyakit pada ibu hamil dengan menerapkan seleksi atribut berbasis Random Forest. Dari enam atribut yang tersedia (usia, berat badan, tinggi badan, usia kehamilan, sistole, dan diastole), tiga atribut utama yaitu sistole, diastole, dan usia kehamilan dipilih berdasarkan Importance Score dari Random Forest. Hasil pengujian menunjukkan bahwa penggunaan tiga atribut ini meningkatkan Silhouette Score sebesar 0,21 (dari 0,23 menjadi 0,44), yang mengindikasikan pemisahan cluster yang lebih baik, serta menurunkan Davies-Bouldin Index sebesar 0,69 (dari 1,50 menjadi 0,81), menunjukkan cluster yang lebih kompak dan terpisah dengan baik. Visualisasi clustering menggunakan Principal Component Analysis (PCA) mendukung hasil ini. Selain itu, perhitungan metode Elbow menunjukkan jumlah cluster optimal pada k=3, memperkuat kesimpulan bahwa pemilihan atribut dan jumlah cluster yang tepat meningkatkan kualitas clustering. Secara keseluruhan, penelitian ini membuktikan bahwa seleksi fitur berbasis Random Forest mampu mengoptimalkan metode K-Means dalam clustering penyakit pada ibu hamil, yang diharapkan dapat meningkatkan efektivitas diagnosis dan perencanaan perawatan.
