Abstract

Work fatigue in the shipping industry needs attention. Based on 2018 ILO data, it is stated that more than 2 million workers in the world die every year due to fatigue caused by work-related diseases or work accidents. Fatigue can be caused by an imbalance in workload. The workload, both physical and mental, must be in accordance with the worker's abilities. Physical load is dominated by physical activity work while mental load is dominated by mental activity or thinking. The aim of this research is to analyze the strong relationship between mental workload and physical workload on work fatigue. The research method includes descriptive research with an observational research design and a cross-sectional approach on welding 1 and welding 2 workers in the commercial division of PT PAL Indonesia. The strength of the relationship between the dependent variable and the independent variable is seen based on the results of the correlation coefficient (r) in the Spearman test. The results of the research show that there is a very strong relationship between mental workload and work fatigue of 0.811 (very strong) between physical workload and work fatigue of 0.847 (very strong). The strong relationship between physical workload and work fatigue is greater than the strong relationship between mental workload and work fatigue.

Abstract

Low Back Pain (LBP) is a widespread health issue that profoundly impacts workers' productivity and quality of life. In addition to non-specific health effects, LBP can result in long-term disability and considerable economic losses. Globally, LBP affects 619 million individuals, with projections suggesting an increase to 843 million by 2050, particularly Low Middle Income Countries (LMICs) in Asia and Africa. The shipbuilding industry, known for its physically strenuous tasks and stringent deadlines, presents unique ergonomic challenges that can exacerbate job-related stress and precipitate the onset of LBP. This study examines Project X PT Y, a pivotal entity in Indonesia's shipbuilding sector. Utilizing a quantitative methodology and a cross-sectional research design, the study encompasses all 26 workers from the welding workshop at Project X PT Y. The analysis, conducted using the Spearman test, reveals a robust monotonic relationship between work-related stress and LBP complaints, indicating that the incidence of LBP increases concomitantly with elevated work stress.

Abstract

The aim of this research is to determine the effect of red sugar cane bagasse waste as a cement substitute on the compressive strength of concrete and to determine the compressive strength value of concrete after adding red sugar bagasse waste as a cement substitute. This research is experimental research which begins with preparation of tools and materials, aggregate inspection, slump test, job mix design, making test objects, caring for test objects, testing concrete volume weight and ends with testing concrete compressive strength. The research results show that the addition of red sugar cane bagasse powder as a cement substitute in making concrete has an effect on the mechanical properties of concrete such as: slump value, concrete volume weight and concrete compressive strength. The average compressive strength value of concrete produced after adding 2.5% red sugar cane bagasse waste; 5%; 7.5% and 10% at 28 days are 20.95 MPa respectively; 17.15 MPa; 14.79 MPa and 11.87 MPa. Thus, red sugar bagasse waste is not recommended to be used as a cement substitute because the compressive strength value of the planned concrete is very far from normal concrete.

Abstract

This study aims to determine the effect of giving ginger decoction to reducing blood pressure in elderly hypertensives. This study used a quasi-experimental design with a pre-post test without control group design. The population in this study were elderly people who suffer from hypertension in RT 07 Wijaya Kusuma, West Jakarta. The number of samples in this study were 22 people using the total sampling technique. The instruments in this study were 4gr ginger, 200cc water, digital scales, honey, knife, measuring cup, and digital tensimeter (automatic). The research results showed that the average systolic blood pressure at the first measurement (pre test) was 141.32 mmHg with a standard deviation of 10.242. In the last measurement (Post Test) the average systolic blood pressure was 132.59 mmHg with a standard deviation of 3.912 while the average diastolic blood pressure in the first measurement (Pre Test) was 94.27 mmHg with a standard deviation of 10.416 and in the last measurement (Post Test) was 81.55 mmHg with a standard deviation of 7.614. Statistical analysis using the paired t-test showed p value = 0.001 so it can be concluded that there is an effect of giving ginger decoction to reducing blood pressure in elderly hypertensives. Based on the results of the study, nurses are expected to be able to provide interventions to address hypertension problems by administering ginger decoction which can lower blood pressure on an ongoing basis without significant side effects and can be used as traditional medicine in patients with hypertension.

Abstract

Liquid waste from the student canteen of FST Jambi University can cause pollution. This study aimed to determine the concentration of COD and oil and fat before and after treatment, and to analyze the effectiveness of zeolite and water hyacinth. The experimental method involved a physical process using zeolite and a biological process using water hyacinth. The initial COD value of the canteen liquid waste was 22,357.28 mg/L, and the oil content was 5,576.12 mg/L. After treatment with zeolite, COD decreased to 2,831.325 mg/L, and oil and fat to 17.92 mg/L. Using a combination of zeolite and water hyacinth for 5, 10, and 15 days, the COD values were 792.25 mg/L, 307.9 mg/L, and 666.67 mg/L, and the oil and fat values were 3.22 mg/L, 6.76 mg/L, and 13.61 mg/L. The effectiveness of zeolite alone resulted in a COD reduction of 87.34% and oil and fat reduction of 99.68%. The combined treatment for 5, 10, and 15 days resulted in COD reductions of 96.46%, 98.62%, and 97.02%, and oil and fat reductions of 99.94%, 99.88%, and 99.76%.

Abstract

Indonesia is known for having abundant biological riches and many plants that can be used as medicine. One of the medicinal plants that is often used by Indonesian people is Jatropha curcas leaves. Jatropha plants are currently used as traditional medicine to treat wounds. One common medication used for cuts is povidone iodine which is effective against bacterial infections. However, povidone iodine also has side effects such as irritation, toxic reactions and burning skin. Jatropha leaves have strong antioxidant activity, so it is necessary to innovate in wound treatment using natural ingredients in the form of gel preparations. The gel preparation was chosen because it is practical, not sticky, easily absorbed by the skin, and works directly on wound tissue. The aim of this study was to assess how well a gel made from ethanol extract of jatropha leaves accelerates the healing of cut wounds in white mice. Jatropha curcas leaves were extracted using the maceration method using 96% ethanol as the solvent. Gel stability testing was carried out organoleptically, homogeneity test and spreadability test. Jatropha leaf extract gel was tested on mice that had been given incisions 1.4 cm long with formulations of 10%, 15% and 20% jatropha leaf extract concentrations. Observations were carried out for seven days. Research findings showed that giving white rats gel containing jatropha leaf extract significantly accelerated their ability to repair wounds

Abstract

Dyslipidemia is one of the main risk factors for cardiovascular disease, and cholesterol management therapy has significant benefits in the primary and secondary prevention of coronary heart disease and stroke. Therefore, lipid-lowering therapy, especially using HMG-CoA reductase inhibitors (statins), aims to assess the effectiveness of using statin-class dyslipidemia medications, such as simvastatin and atorvastatin, in reducing LDL levels in cardiovascular patients at X Hospital. This research method uses an observational analytic study with a retrospective research design. This study employs the purposive sampling method. The results of this study show that the majority of patients are female (75%). Based on age grouping, it was found that the highest proportion of patients were aged 56-65 years, accounting for 45%. The use of dyslipidemia drugs that achieved the target LDL reduction ≥ 50% includes Simvastatin 10 mg (33.82%), Simvastatin 20 mg (11.94%), Atorvastatin 10 mg (10.45%), and Atorvastatin 20 mg (41.79%). The most effective drug in achieving the LDL reduction target was Atorvastatin 20 mg.
