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.

Oxidative stress leads to numerous clinical problems, such as autoimmune, vascular and respiratory impairment, as well as many other degenerative diseases. While daily exposure to UV light, air pollution, and smoke largely contribute to oxidative stress, endogenous antioxidants mostly fail to neutralize these high amounts of free radicals. Stevia rebaudiana or “candyleaf” is largely found in Indonesia, known for its application as a natural sweetener, owing to its content of stevioside compound. This study is experimental research which aims to assess the potential of stevia extract as an antioxidant supplement, which has not been widely applied. In vitro study was performed by extracting stevia leaves in methanol through simple maceration and percolation methods. Subsequently, the stevia extract was subjected to biochemical analysis, i.e. phytochemical screening, total phenolic content assay, antioxidant capacity assay, and toxicity assay. Herein, we found that stevia extract contains flavonoid, saponin, tannin, terpenoid, and phenolic compounds, with total phenolic content of 86.30±1.14 mg GAE/g DW. Moreover, antioxidant capacity assay through 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) method showed that IC50 of stevia extract is 20.13 µg/mL, slightly higher than Trolox (vitamin E analog) with IC50 of 16.50 µg/mL, which indicated that stevia extract is a very strong antioxidant. As for toxicity bioassay, Brine Shrimp Lethality Test indicated that stevia extract is non-toxic with LC50 value of 3388.44 µg/mL.

Published: January 2025

This study examines the impact of Electronic Medical Records (ERM) implementation in healthcare facilities over the last decade, focusing on its benefits and challenges. ERM has significantly improved patient care quality, operational efficiency, and data security, providing fast and accurate access to medical information for clinical decision-making. However, despite these advantages, the adoption of ERM faces several technical and organizational challenges, including limited interoperability between systems and user resistance. A systematic literature review was conducted, analyzing studies from 2014-2024, to explore both the positive outcomes and barriers encountered during ERM implementation. The results indicate that while ERM reduces medical errors and enhances care coordination, particularly in managing chronic conditions, issues such as data privacy concerns and high implementation costs remain significant barriers. Recommendations to address these challenges include the development of standardized policies for system interoperability and comprehensive user training to facilitate adaptation. This study underscores the need for a more integrated approach that combines technical improvements with organizational support to maximize the potential benefits of ERM.

Published: January 2025

Fish farmers in Gresik Regency face significant challenges in developing aquaculture, including land conversion and extended dry seasons that lead to pond drought. Microbubble generators (MBGs) present a potential solution to these issues. This study evaluates the effectiveness of different MBG types in tilapia farming. Weekly measurements of fish mass and length were conducted to determine growth rates using direct methods. Water quality was assessed by testing COD and ammonia levels at the Gresik Regency DLH Laboratory and measuring dissolved oxygen levels directly with a DO meter. The distribution and size of the bubbles were analyzed using the shadow image technique, supported by MATLAB software. The study employed a stocking density of 100 fish/m² with three treatments: MBG swirl type, venturi type, and a conventional aerator. The findings revealed that the MBG swirl type resulted in the best fish growth and maintained water quality within the required standards. The specific growth rate in swirl-type ponds was 3.970 ± 0.014, with a survival rate of 100%. Additionally, the swirl-type MBG effectively maintained dissolved oxygen levels above 3 ppm, meeting the minimum requirement for fish survival, despite having less optimal microbubble distribution compared to the venturi type. While the MBG venturi type performed well initially, technical issues affected its bubble consistency over time. Enhancements in the venturi MBG's design are recommended to improve its performance and reliability.

Stress, environmental pollution, radiation, and excessive food processing contribute to the production of free radicals, which are harmful to the body. Antioxidants play a role in preventing free radicals from damaging nucleotides. Ginger contains high levels of antioxidants, making it beneficial for overall health. However, ginger has a short shelf life, and its traditional preparation methods are less preferred by many people. Therefore, ginger is now available in the form of instant drink powders, which can be prepared like tea or coffee. This study is a descriptive study using the hedonic test method. Thirty students were selected as panelists. The panelists evaluated two types of ginger drinks made with different sweeteners: sugar and a combination of sugar and palm sugar (sugar-palm sugar). The parameters assessed in this study were color, aroma, taste, and sweetness level. The results of the hedonic test showed that the ginger drink sweetened with the sugar-palm sugar combination had the highest preference percentages across all parameters: color, aroma, taste, and sweetness level. For color, the "like" preference level achieved a percentage of 40%. For aroma, the "really like" preference level reached 43.33%. Taste received a "really like" preference level of 53.33%, and sweetness achieved a "like" preference level of 36.67%. In conclusion, the panelists preferred the ginger drink sweetened with the sugar-palm sugar combination over the drink sweetened with just sugar. This preference is attributed to the addition of palm sugar, which balances the ginger's strong flavor while retaining its distinct taste. Furthermore, the combination of ginger and palm sugar produces a harmonious blend of color, aroma, taste, and sweetness that complements both ingredients.

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.

Robusta Coffee Leaves are known to have high antioxidants that can stabilize free radical attacks. Based on the height of the place where Robusta Coffee grows, it has different characteristics, including producing different qualities and flavors from one another. This study aims to determine the content of phytochemical compounds and the antioxidant activity of Robusta coffee leaves based on differences in the height of the place where it grows. The research method used was sampling at several heights including 511 masl, 434 masl, 354 masl, 204 masl, 122 masl, and laboratory research for phytochemical and antioxidant tests. Data analysis used the ANOVA, DMRT, and Bivariate correlation tests to determine the correlation between height and antioxidant activity. The results showed that all five heights contained alkaloid and flavonoid compounds. The highest inhibition of antioxidant activity was found at an altitude of 511 masl with a percentage of 61.89% ±8.08b, while the lowest inhibition of antioxidant activity was found at an altitude of 122 masl with a percentage of 31.92% ±7.38a. Antioxidant activity at all five altitudes is classified as a very strong antioxidant with an IC50 value <50. Altitude has a significant effect (P<0.05) on antioxidant inhibition. Altitude has a positive correlation with antioxidant activity.

Chicken meat is a source of animal protein that can be processed into various food products, including jerky, offering a more economical alternative without compromising taste and quality, although it has the drawback of less appealing color. This study aims to determine the optimal concentration of angkak (Monascus purpureus) as a safe natural colorant to enhance the color of minced chicken jerky and evaluate the effects of angkak concentration and oven temperature on its physicochemical properties, total plate count (TPC), and organoleptic characteristics. The study used a Completely Randomized Design (CRD) with four treatments combining angkak concentrations (1% and 3%) and oven temperatures (80°C and 100°C), each replicated three times. The analyzed parameters included color (L, a, b), moisture content, protein content, TPC, and organoleptic properties (taste, color, aroma, texture). The results of the study showed that adding angkak significantly increased red color intensity and antibacterial activity, while oven temperature affected moisture and protein contents. The best treatment was found at 3% angkak concentration and 100°C oven temperature, yielding dark red color, protein content of 27.13–30.06%, TPC of 0.022 x 10⁵ CFU/g, and high organoleptic acceptance. Thus, angkak canibe usedtas asnatural colorant and preservativeKfor minced chicken jerky.
