Abstract

The use of urinary catheters is very common in hospitals. Urinary catheters are the most common cause of bacteriuria. Urinary tract infections are the cause of more than 1/3 of all hospital-acquired infections. Most of these infections (at least 80%) are caused by invasive procedures or urinary tract instrumentation, usually in the form of catheterization. Urine sediment examination aims to detect and identify insoluble materials in urine. The purpose of this study was to determine the prevalence of leukocyte counts in patients with catheter placement based on a literature review and to analyze the number of leukocytes in patients with catheter users based on a literature review. The method used was Systematic Literature Review (SLR). The results of this study obtained the results of the number of samples based on gender in women as many as 223 people and in men 147 people, with a total number of patients as many as 370. then the results of the number of samples based on patient age, the number of patients who were most catheterized at the age of 56-65 as many as 101 patients (27.0%), followed by age 46-55 as many as 96 patients (25.0%), age 36-45 as many as 68 patients (18.0%), age 26-35 as many as 39 patients (10.0%), age 17-25 as many as 30 patients (8.0%), and age> 65 as many as 36 patients (9.0%) with a total of 370 patients. The results of the study can be concluded that catheter installation can cause urinary tract infections.

Abstract

Tuberculosis is an infectious disease caused by the Mycobacterium tuberculosis bacteria which usually attacks the lungs but can also attack other organs such as lymph nodes, heart and so on. Tuberculosis is transmitted through the air, from one person to another, usually through the sputum droplets of someone who has had TB. Anaemia in Tuberculosis can be caused by disruption of the erythropoiesis process by inflammatory mediators, shortening of the life span of erythrocytes, impaired iron metabolism, malabsorption, and inadequate nutrition due to low appetite. The research method used is descriptive. Where this study will describe how the erythrocyte index is in tuberculosis patients who take medication for 1 month, 2 months, 3 months, 4 months, 5 months, and 6 months of treatment. The total respondents in this study were 20 respondents, including 10 men and 10 women. Based on the results of the erythrocyte index count, the type of erythrocytes shows the number of respondents with Hypochromic Microcytic anaemia as many as 6 people, Normochromic Microcytic anaemia as many as 3 people, Hypochromic Normocytic anaemia 1 person and Normochromic Normocytic anaemia as many as 10 people.

Abstract

The Human Development Index (HDI) is a composite indicator that reflects the quality of life of a population through three primary dimensions: health, education, and a decent standard of living. Improvements in HDI are supported by advancements across all its constituent factors. The dimension of long and healthy life is represented by the increase in life expectancy (LE), while the education dimension is captured through the rise in the mean years of schooling (MYS) and expected years of schooling (EYS). Additionally, the standard of living dimension is indicated by improvements in adjusted per capita expenditure. This study aims to analyze the factors that determine HDI in Indonesia in 2023 using multiple linear regression analysis. The data used in this study are secondary data sourced from the Central Statistics Agency in the form of Human Development Index data and the factors that influence it. The findings reveal that variables such as Life Expectancy (LE), Expected Years of Schooling (EYS), Mean Years of Schooling (MYS), and Adjusted Real Per Capita Expenditure significantly affect the Human Development Index in 2023. This is evidenced by an R-Square value of 0.9957, indicating that the independent variables collectively explain 99.57% of the variance in the dependent variable.

Abstract

Stunting is a global health issue that affects children’s quality of life, and its prevalence remains high in Indonesia, including in West Lombok Regency. This study aims to analyze the messages delivered through the integration of health promotion and epidemiology communication via mosque speakers in Karang Bongkot Village, as well as the role of mosque caretakers in supporting stunting prevention efforts. A qualitative case study approach was employed, with interviews conducted with mosque caretakers, pregnant and breastfeeding women, healthcare workers, and religious leaders. The findings revealed that the messages conveyed included the importance of balanced nutrition, exclusive breastfeeding, and routine health checkups. The mosque caretaker plays a crucial role in delivering information to the community, supported by healthcare workers and religious leaders who provide legitimacy to the messages. Community-based communication strategies through mosques are effective in raising awareness about stunting prevention. This study concludes that integrating health promotion communication through mosques can be an effective solution in addressing stunting in the community.

Abstract

The water level data is closely related to the water discharge data in the Pesongoran Kuripan channel in West Nusa Tenggara Province. Daily data is needed by farmers to maintain the quantity of water and the quality of agricultural products. Altitude data is taken daily by irrigation workers, but the data is often available in an incomplete state. This paper aims to correct incomplete data on water level data in irrigation canals using the Cubic Spline Interpolation algorithm. This is due to the nature of the data that depends on the climate (seasonal). Therefore, Cubic Spline can be a solution to incomplete data. The first step, create a set of coordinate points from the primary data.The second step is to create a tridiagonal matrix consisting of a lower triangle matrix, a diagonal matrix and an upper diagonal matrix. The third step is the constant search using Gauss-Jordan elimination. The effectiveness of the Cubic Spline method can be seen from the error of the comparison between the set of coordinate points and the coordinate points of the interpolated results. The smaller the error, the more appropriate the expected result . The results of the study prove the effectiveness of Cubic Spline in missing data.

Abstract

The Construction Cost Index (CCI) is an index that describes how expensive it is to build a building, the higher the index, the greater the cost. Meanwhile, the Human Development Index (HDI) is an index used to measure the quality of life of the people in a region, the higher the value, the better the quality of life. It is important to know how the pattern and dynamics of the relationship between CCI and HDI. Therefore, this paper aims to determine the relationship between CCI and HDI in West Nusa Tenggara Province. The data taken is secondary data derived from Central Bureau of Statistics. First, define the hypothesis between CCI and HDI, where CCI and HDI are assumed to have a negative relationship, which means that the higher HDI, the lower CCI, and vice versa, the lower HDI, the higher CCI.The average CCI in West Nusa Tenggara falls into the high category, as does the HDI. After that, compare the CCI and HDI values in each region with the previous region, where Makassar City is used as the initial comparison for the CCI category, as it is the region closest to or equal to the national average index. As a result, most regions show the hypothesized negative relationship. out of 10 regions, only Sumbawa District, West Sumbawa District, and Bima District show a negative relationship.

Abstract

This study aims to investigate the process of consumer price enumeration at the traditional Pagesangan Market, Mataram City, during July 2024, and analyze the percentage changes in commodity prices between June and July 2024. The research employs a descriptive qualitative approach, involving systematic steps such as field observations, formation of an enumeration team, training on survey methods, and direct data collection using questionnaires. Results indicate significant price fluctuations among key commodities: mackerel and cayenne pepper recorded price increases of up to 35% and 30%, respectively, due to limited supply and disrupted harvests. In contrast, tomato prices fell sharply by about 40% due to a surplus during the peak harvest season. Analysis reveals that seasonal factors, supply chain dynamics, and consumer demand are the primary drivers of these changes. The findings highlight the importance of maintaining price stability through targeted policies, particularly for essential goods that directly affect consumer purchasing power.

Abstract

The Linear Least Square Approximation method is applied to predict rice prices in West Nusa Tenggara (NTB) Province. The price of rice plays a strategic role in the Indonesian economy as it is the basic need of most people, and its fluctuations have a significant impact on purchasing power and economic stability. Various factors influence changes in rice prices, such as production volume, climate conditions, and the possibility of price manipulation by certain parties. In this analysis, the Least Square Approximation method was chosen because it is able to capture trend patterns based on historical data from 2015-2022 obtained from the Central Statistics Agency (BPS), thus helping to project future prices. The prediction results show that rice prices in the period tend to be stable in the range of IDR 8,900 to IDR 9,800 per kilogram. The accuracy of the model was evaluated using Mean Absolute Percentage Error (MAPE), which resulted in an error of 2.59%, indicating that the method is effective and reliable enough to provide accurate rice price predictions.
