Abstract

The study investigated the emergence and early seedling development of Monodora myristica in six different growth media viz: mixture of river sand/top soil, river sand/saw dust, top soil/saw dust, saw dust only, top soil only and river sand only. Results obtained recorded highest percentage germination (63%) in seeds sown in saw dust only. Early seedling growth was observed for four months. The results of this study showed that seedlings sown in mixture of top soil/saw dust recorded highest mean plant height (16.83cm), stem girth ( 2.50mm), and leaf area (46.18cm2) at the end of the experimental time. Seedlings on top soil only had the highest number of leaves (3.89). River sand had the least seedling performance in all the growth parameters examined; plant height (13.27cm), stem collar girth (1.99mm), leaf length (8.61cm), leaf width (4.77cm) and leaf area (30.83cm2). The study established that the % emergence of Monodora myristica seedlings was best in saw dust medium while mixture of top soil/saw dusts is recommended for enhancing early seedling growth of this plant in the nursery.

Abstract

Breast cancer is a very serious disease and requires the sufferer to undergo an intensive examination. This study proposes an optimization method for SVM parameters using the particle swarm optimization algorithm to classify breast cancer. The test results show that the classification using SVM with optimization using PSO is able to improve accuracy better than the classification using SVM without optimization, namely the determination of the parameters randomly. Breast cancer data classification accuracy increased to 78.91%. The best parameter values for c, γ, r, and d are 0.252101, 0.053248, 1 and 5, respectively. In this study, the polynomial and RBF kernels in general were able to produce higher accuracy than linear and sigmoid kernels.

Abstract

This study aims to explore the potential of agroforestry ecosystems in maintaining the balance of the rice field ecosystem. Two rice fields around agroforestry with different types of agroforestry were selected, namely rice fields adjacent to simple agroforestry and complex agroforestry in Gunungcupu Village, Sindangkasih District, Ciamis Regency, West Java. Arthropod species data were obtained using a mask and suctioning was carried out with an aspirator. There are 40 sample plots at each Location. Plots were placed systematically in rice fields adjacent to agroforestry with a distance between plots of 10 m and a distance between plots of 10 m. Observations were made since the beginning of the first planting period, September 20 2018, continued during the planting interval and ended in the last week of the second planting period on June 14 2019. Based on the analysis results, it was found that the even distribution of predatory arthropod species in the rice fields was not affected by the planting period. The planting interval also did not affect the diversity and even distribution of insect predatory arthropod species. This condition indicates that agroforestry areas have the potential to support the diversity of arthropod species in paddy fields.

Abstract

Low birth weight (LBW) is often found in premature birth or because of early gestational age. Several studies have evaluated the impact of Acute Kidney Injury (AKI) on neonates. Birth weight is an important predictor of the nephron and glomerular mass. Mortality in infants with AKI is significantly higher than in those without AKI. Objectives: To analyze the correlation between birth weight and the degree of kidney function disorders. Methods: This study uses an observational analytic approach with a cross-sectional research design. Eighty-nine patients from patients treated from January 2019 to December 2020 were obtained using total sampling. Patient demographic data were collected, and Spearman's test was performed to see the relationship between LBW and the level of impaired renal function in neonates. Results: During the study, 89 samples were obtained, where the mean body length of the neonates was 44.46 ± 2.22 cm, the ureum range was 6-189 mg/dL, the creatinine range was 0.20 -4.03 mg/dL, mean GFR was known to be 19.01+8.96 ml/min/1.73 m2. The highest number of neonates was in the 34–36-week gestational age group. The average birth weight was 1,964.94 ± 274 g, with a range of 1,500-2,400 g. Most neonates had kidney function of risk (31.5%) and injury (30.3%). Only 15 (16.9%) neonates were not affected. Conclusion: There is a significant relationship between birth weight and the level of impaired kidney function (p < 0.05). The correlation coefficient of 0.217 indicates a weak correlation. There was no relationship (p= 0.061) and no significant correlation between gestational age, low GFR (r= 0.189).

Abstract

Epilepsy is a chronic disease that causes social function barriers that affect quality of life. Clinical factors, demographics, psychosocial, and anti-epileptic drugs are reported to affect the quality of life of people with epilepsy. This study aims to assess the quality of life of children with epilepsy who seek treatment at the IKA section of RSUDZA. This research is an observational analytic study with a cross-sectional design at the neurology polyclinic and inpatient Dr. RSUD. Zainal Abidin Banda Aceh for the period April-May 2021. The research subjects are 2-18 years old. Quality of life assessment using generic PedsQLTM 4.0. Multivariate analysis was tested using logistic regression test. It was found that 60 epilepsy patients participated in the study and obtained a quality-of-life disorder based on parent reports of 28.3%, and children's reports of 34.1%. There was no statistically significant relationship between demographic factors and children's quality of life based on parental reports (p< 0.05). In the children's report, it was found that demographic factors in the form of unexpected parenting were risk factors for impaired quality of life (p <0.05). Abnormal EEG picture is a clinically significant factor for impaired quality of life in children with epilepsy (p<0.05). This study concludes that patients with risk factors namely unexpected parenting, abnormal EEG affect quality of life.

Abstract

In general, the water pump is often used automatically, according to the use of the water faucet when it is opened. This automatic water pump system often triggers a surge in electric current when the water pump is on or off. This surge in electric current will increase compared to the nominal electric current. With increased current capacity, sometimes we face problems with the quality of electrical power in the electrical system, and will also increase electricity bills. The purpose of this research is to improve the quality of power to save electricity, reduce electric current when the water pump is used, so as to reduce the cost of using electricity bills, especially for water pumps. The use of Varistors in the Inverator Starting Energy Saver circuit is very influential in protecting the load when there is a surge in current even though it is momentary or long, so that it can improve the quality of electrical power at the water pump load. The data is carried out on measuring current, voltage, cos phi and frequency when the water pump is used without using an inverator. After making these measurements the measurement data can be saved as a comparison for the measurement data, which uses the installation of an inverator starting energy saver which is connected in parallel with the power source and also connected to the water pump. By installing the inverter starting energy saver circuit to improve the quality of electric power. The use of a varistor in the inverator starting Energy saver circuit clearly produces a current of 1.274 A and the voltage is 216 V without using an inverator. Furthermore, when using the inverter circuit, it produces a current of 1.098 A and the voltage drops by 207.6 V. The decrease in the working voltage of the water pump is still within the standard 5%.
