Abstract

This study employed an observational analytic design with a cross-sectional approach to examine the impact of hospital brand image on patient loyalty in private Islamic hospitals in Mataram. Data were collected from 223 patients at RSI Siti Hajar Mataram using structured questionnaires. The sample was selected through proportional stratified random sampling, ensuring representation across various hospital care classes.The findings of this study reveal that: (1) a positive hospital brand image significantly correlates with patient loyalty (p ≤ 0.001); (2) 96.5% of patients with a positive perception of the hospital’s image demonstrated high loyalty; (3) demographic factors, such as age, gender, and education level, influence patients’ perceptions of the hospital brand image; and (4) Muslim patients exhibited higher loyalty levels compared to non-Muslim patients, highlighting the relevance of Islamic values in healthcare services.The study underscores the critical importance of developing a positive brand image to enhance patient loyalty. Hospitals should adopt comprehensive strategies to improve service quality, ensure effective communication, and align their services with patients’ cultural and religious values. These efforts can foster trust, strengthen the hospital’s reputation, and secure long-term patient retention, particularly in culturally sensitive contexts.

Abstract

Tuberculosis is an infectious disease that spreads through the air and is caused by the bacterium Mycobacterium tuberculosis. To combat it, synthetic drugs are commonly used, which can have adverse effects, making natural alternatives like avocado mistletoe (Dendrophthoe pentandra) necessary. This study aims to explore potential tuberculosis compounds from D. pentandra. The method used in this research is an exploratory descriptive method. The identification of compound content in the ethanol extract of D. pentandra leaves was performed using GC-MS, along with potential testing as an antituberculosis agent through in silico molecular docking. The research results showed that there were 13 volatile compounds contained in the ethanol extract of D. Pentandra leaves, predominantly consisting of propane, 1-methoxy, with a concentration of 9.39%. D. pentandra has the potential as a ClpP1P2 antituberculosis agent with four promising compounds:2-amino-1-(5-bromo-2-pyridinyl)-4-(2,4-dichlorophenyl)-7,7-dimethyl-5-oxo-1,4,5,6,7,8-hexahydro-3-quinolinecarbonitrile, stigmasterol acetate, β-sitosterol acetate, and γ-sitosterol. PASSOnline predictions support the potential of ethanol extract of D. Pentandra leaves as anti-tuberculosis and anti-mycobacteria agent.

Abstract

Sembilang is one of the fish that is abundant in Merauke mainland waters. Genetic research needs to be done to prevent the decline of catfish population. DNA barcoding is a taxonomic method that uses short genetic markers in an organism's DNA to identify species. This research aims to identify the Sembilang fish species using the Cytochrome Oxidase I gene. This study is an exploratory survey research. Sample collection was carried out in the waters of Padi Swamp, Merauke Regency. The mitochondrial cytochrome oxidase I (COI) gene was amplified using the Polymerase Chain Reaction (PCR) method with FISH-BCL and FISH-BCH primers. The results of analysis using DNA barcoding revealed that the samples collected were the Sembilang species (Neosilurus ater) with a DNA sequence length of 660 bp. Phylogenetic reconstruction using the Neighbor-Joining method with the 2-Parameter Kimura Model shows sequence grouping based on similarity and genetic distance between species.

Abstract

Diabetes Mellitus (DM) is a metabolic disease characterized by hyperglycemia caused by defects in insulin secretion, insulin action, or both. The number of people with DM has increased to approximately 463 million individuals aged 20-79 worldwide. Several complications can arise due to DM, one of which is gangrene wounds. Gangrene wounds are the most common microvascular complication in DM patients. Nutritional intake is a crucial component in the wound healing process. The aim of this study is to determine the relationship between diet and the degree of gangrene in DM patients. The method used is an observational analytical approach with a cross-sectional design. The sample size consists of 51 respondents obtained from medical records and questionnaires filled out by DM patients. Data analysis was conducted using the Chi-Square test. The results showed that 23 respondents had a moderate diet (45.1%), and the majority of respondents had wounds classified as degree 3 (21.6%). A significant relationship was found between diet and the degree of gangrene in DM patients (p<0.005). Thus, it can be concluded that a significant relationship exists between diet and the degree of gangrene in DM patients

Abstract

This study aims to determine the levels of blood plasma protein in pregnant white rats (Rattus nervagicus) that consume Organic MSG and Synthetic MSG. This research method is experimental using a Completely Randomized Design (CRD) by random sampling 21 pregnant white rats with 3 replications and 7 treatments consisting of positive control treatments, P1 = 0.5 ml Organic MSG, P2 = 1 ml Organic MSG, P3 = 2 ml Organic MSG, P4 = 0.5 ml Synthetic MSG, P5 = 1 ml Synthetic MSG, P6 = 2 ml Synthetic MSG for 19 days. The variables measured were blood plasma protein levels measured using a refractometer with units of g / dL. The data tested using SPSS analysis with one way ANNOVA test then continued with Duncan's Multiple Range Test (DMRT). The results showed that Organic MSG had a positive effect on blood plasma protein levels which were significant to the difference in blood plasma protein levels. This can be implied in the health of pregnant rats if there is MSG that enters it will provide viscosity to the blood so that blood plasma protein will be high working hard to produce white blood cells to balance red blood cells that affect immunity. The blood plasma protein levels of pregnant white rats given liquid Organic MSG were the highest at 13.562 g/dL and the lowest at 13.55 g/dL.

Abstract

Macroalgae are photosynthetic organisms that grow in aquatic environments and play an important role in marine and coastal ecosystems. Macroalgae grow in almost all waters, including in the coastal area of Batu Layar. Batu Layar has particular and distinctive characteristics compared to other locations on Lombok Island. However, in recent years, supporting tourism facilities have begun to be built which will affect the composition of living biota including macroalgae. Therefore, data was collected on the diversity of changes in the composition of macroalgae in the future. This study aims to determine the diversity of macroalgae growing on Batu Layar Beach, West Lombok. This study is a descriptive exploratory study. Quadrant placement and sampling were carried out using the purposive sampling method. The results showed that the number of species growing in Batu Layar waters was 41 species. These species are spread across two observation stations. Station 1 is dominated by S. polycystum while station 2 is dominated by P. australis. The current strength and depth parameters of Station 1 were higher than those of Station 2, while the ammonia, phosphate and turbidity of Station 2 were higher than those of Station 1.

Abstract

Carrageenan is widely used in various industries, such as food and beverages, cosmetics, and pharmaceuticals, due to its important role as a viscosity regulator, stabilizer, thickener, developer, gelling agent, and excellent stabilizing agent. Temperature and drying duration are important factors that affect the quality of the final product. This study aims to examine the quality characteristics of carrageenan from Eucheuma spinosum dried using the oven method, considering variations in temperature and drying time. This study used a completely randomized design (CRD) with two factors: temperature and drying time, each of which was repeated three times. Eucheuma spinosum was extracted using the microwave-assisted extraction (MAE) method with 10% KOH solvent in a ratio of 1:10 for 8 minutes. The first factor is the drying temperature, which consists of three levels: 40°C, 50°C, and 60°C. The second factor is the drying time, which also consists of three levels: 24 hours, 27 hours, and 30 hours. The results of the study showed that (1) temperature and drying time affect the quality characteristics of carrageenan from Eucheuma spinosum dried using the oven method, (2) the parameters affected include water content, ash content, sulfate content, viscosity, and gel strength of carrageenan, and (3) the higher the temperature and duration of drying, the more the water content, ash, protein, and crude fiber in the product tend to decrease. This decrease is in line with the viscosity and gel strength of the resulting carrageenan.
