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

This study aims to analyze the multicollinearity of environmental variables in the Bakongan-Bengkung Forest, part of the Leuser Ecosystem, to understand its implications for the habitat of key species such as Sumatran elephants, Sumatran rhinoceros, Sumatran tigers, and Sumatran orangutans. The research was conducted in August 2023 across an area of 75.912,46 hectares spanning three districts in Aceh. The data utilized includes elevation, slope, river density estimation, Normalized Difference Vegetation Index (NDVI), distance from roads, and annual rainfall, sourced from various geospatial datasets. Data processing was performed using ArcGIS 10.3, Google Earth Engine (GEE), and RStudio 4.2.2. Multicollinearity testing was carried out using Pearson correlation coefficients to identify relationships between environmental variables. The analysis revealed a significant positive correlation between elevation and annual rainfall, with a correlation coefficient of 0,724, indicating a strong linear relationship. This correlation suggests that higher elevations in the area are associated with increased rainfall, likely due to orographic effects. These findings are crucial for conservation planning and habitat management for wildlife. The correlation between elevation and annual rainfall should be considered when developing accurate habitat models for key species in the Bakongan-Bengkung Forest, to ensure effective and sustainable conservation strategies.

Abstract

Betta fish is a freshwater ornamental fish with a unique body shape and the brightness of its color is one of the attractions among its fans. The increase in color intensity and growth in betta fish is greatly influenced by the nutrient content in the feed and genetics. Adding Spirulina platensis flour to feed is expected to increase feed nutrients such as beta carotene, which is known to increase the intensity of color and growth of betta fish. This study aims to prove whether adding Spirulina platensis flour to feed can increase the intensity of color and growth of betta fish. The experimental research used a Complete Random Design (RAL) with 4 treatments and 3 replicates, namely P0 (0%), P1 (3%), P2 (5%), P3 (7%) for 3 months. The parameters measured were color intensity and growth. Test F to determine the effect of treatment on parameters, if there is a real influence, the Duncan test is carried out The test fish in the study is a one-month-old, blue, and male betta fish seed. The results showed that the addition of Spirulina platensis flour to P1 treatment feed (3%) experienced the highest increase in color intensity (P<0.05) followed by P2 treatment (5%), then P3 treatment (7%) and finally P0 treatment (0%). The P1 treatment (3%) was shown to be optimal in increasing the intensity of the color of betta fish but was not followed by an increase in growth.

Abstract

Tempeh is an affordable source of plant-based protein for the community. The fortification of tempeh with coriander (Coriandrum sativum), garlic (Allium sativum), and cardamom (Amomum cardamomum) is important to study because these three spices contain bioactive compounds that potentially increase the protein content and nutritional value of tempeh. This research is necessary to scientifically examine the effect of spice fortification on tempeh protein levels as an effort to develop functional food. The testing method used in this study was the Kjeldahl method referring to SNI 01-2891-1992. Tempeh fortification with coriander showed the most significant increase in protein content, reaching 7.03%, compared to tempeh without spices, garlic, and cardamom, which only increased protein content to 2.74%, 2.92%, and 3.94%, respectively. This is due to the high protein content in coriander, approximately 17-20% per 100 grams of material, which significantly enriches the protein content of tempeh. In contrast, garlic and cardamom have lower protein content, around 6-7% and 9-11% per 100 grams of material, making their contribution to increasing tempeh protein content less significant. This research demonstrates that the use of coriander as a fortification ingredient can be an effective strategy to enhance the nutritional value and protein content of tempeh, making it a more functional and nutritious choice for consumers.
