Abstract

This study aims to analyze the relationship between healthcare service capacity and referral rates at Puskesmas within BPJS Kesehatan Mataram Branch in 2024. This study used a correlation design with a cross-sectional approach. This design aims to evaluate the relationship between the service capabilities of health centers and referral rates at a certain time. The results of the study showed that Puskesmas with inpatient services tend to have safer referral rates compared to non-inpatient Puskesmas. Non-inpatient Puskesmas often refer more cases due to their limited capacity to manage complex cases at the primary level. The results emphasize the need for increased resources and medical training, especially in non-inpatient Puskesmas, to reduce unnecessary referrals to higher-level hospitals. Strengthening service capacity at Puskesmas is essential to ensure effective primary care and reduce the burden on referral hospitals.

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.
