Abstract

Barramundi (Lates calcarifer) is a valuable brackish and marine fish species with high aquaculture potential. This research aimed to evaluate the effect of different stocking densities on growth performance and feed efficiency. A completely randomized design (CRD) was used in a uniform floating net cage (FNC) system with four stocking densities: P1 (20 fish/m³), P2 (30 fish/m³), P3 (40 fish/m³), and P4 (50 fish/m³), each with three replications. Results showed that absolute length growth ranged from 1.17 to 2.33 cm, absolute weight growth from 2.36 to 4.43 g, specific growth rate from 0.94 to 1.93%/day, and feed conversion ratio (FCR) from 1.22 to 2.03. The best growth and FCR were observed in P1 (20 fish/m³), while higher densities resulted in reduced performance. The study concludes that lower stocking densities enhance growth and feed efficiency in barramundi aquaculture. These findings provide valuable insights for optimizing stocking strategies to improve productivity and sustainability.

Abstract

Calliandra (Calliandra sp.) is a shrub with multiple benefits, including its use as firewood and as a high-protein livestock feed. Sengon (Paraserianthes falcataria) is a fast-growing tree species widely cultivated to support the timber industry. To enhance seedling growth and productivity, environmental manipulation through shading and fertilization is necessary. This study aims to evaluate the effects of shading and NPK fertilizer doses on the growth of Calliandra calothyrsus and Sengon seedlings in the context of industrial forest plantation management. Using a completely randomized design, this study tested four shading levels (no shading, 25%, 50%, and 75%) and four NPK fertilizer doses (0, 1, 2, and 3 g per seedling). Each treatment was repeated twice, resulting in a total of 248 seedlings per species. The observed variables included height, diameter, and leaf count. The results showed that Calliandra exhibited no significant differences in height growth across shading levels. However, the best growth was observed under 25% shading, with a height increase of 11.84 cm and a diameter of 1.55 mm, and at an NPK dose of 2 g, with a height of 10.75 cm and a diameter of 1.54 mm. Meanwhile, Sengon showed the best height growth under 75% shading with an NPK dose of 1 g per seedling. The optimal diameter growth for Calliandra was achieved under 25% shading with an NPK dose of 1 g, while Sengon exhibited the best diameter growth without shading and with an NPK dose of 3 g.

Abstract

Bacterial infections are a growing global health challenge, especially with the increasing cases of antibiotic resistance. This study used a true experimental method with a posttest-only control group design to investigate the antibacterial efficacy of roselle flower (Hibiscus sabdariffa L.) ethanol extract against the bacteria Staphylococcus aureus, Escherichia coli, and Propionibacterium acnes. The maceration method was used to extract the roselle flowers using 70% ethanol as the solvent, and the disc diffusion method was used to test for antibacterial activity at extract concentrations of 30%, 40%, and 50%, using the antibiotic chloramphenicol as a positive control. The results showed that the roselle flower ethanol extract exhibited antibacterial activity against all three test bacteria. The highest inhibition zone against E. coli was found at 50% concentration (9.87 mm), classified as moderate. For S. aureus, the 50% concentration produced the highest inhibition zone (18.13 mm) with strong classification, while 30% and 40% concentrations also demonstrated strong inhibitory effects. For P. acnes, all extract concentrations showed strong inhibitory responses with the highest inhibition zone at 50% concentration. Chloramphenicol antibiotic consistently demonstrated higher antibacterial activity across all test bacteria. Statistical analysis revealed significant differences in inhibitory effectiveness based on extract concentration and bacterial type (p<0.001), with a significant interaction between these two factors (η²=0.605). These findings indicate the potential development of roselle flower ethanol extract as a natural antibacterial agent, although further optimization is needed to enhance its effectiveness.

Abstract

In the pursuit of innovative agricultural practices, the Deep Flow Technique (DFT) hydroponic system has gained popularity to meet the increasing demand for vegetables, such as lettuce. However, finding effective organic fertilizers remains a challenge. This study aimed to investigate the impact of using bokashi from goat manure and human urine on lettuce growth within the DFT system, comparing it to the commonly used AB Mix fertilizer. The experiment observed growth parameters, including root length, number of leaflets, and leaf width, for a period of 28 days. The results indicated that the AB Mix fertilizer yielded the best growth, followed by a combination of goat manure bokashi and human urine, whereas human urine alone resulted in the lowest growth. Statistical analysis confirmed the significant influence of the fertilizer treatments on plant growth. These findings suggest that while AB Mix fertilizer is the optimal choice, the combination of goat manure bokashi and human urine proves to be a viable alternative for organic fertilizer.

Abstract

Open wounds are tissue damage that increases the risk of infection and requires proper treatment. Castor leaves (Jatropha curcas L.) contain flavonoids, saponins, and tannins, which have anti-inflammatory and antiseptic properties, aiding in tissue regeneration and infection prevention. To enhance its effectiveness, the extract is formulated into a transdermal patch, allowing direct drug absorption through the skin with stable release and convenient application. This study aims to determine the best formulation and optimal concentration of Hydroxypropyl Methylcellulose (HPMC) and Polyvinylpyrrolidone (PVP) in transdermal patches to improve stability and release effectiveness of the active compounds from castor leaf extract while evaluating their potential in accelerating wound healing. The transdermal patches were prepared using three variations of HPMC and PVP concentrations: F1 (HPMC 1 g : PVP 0.5 g), F2 (HPMC 0.75 g : PVP 0.75 g), and F3 (HPMC 0.5 g : PVP 1 g). Evaluations included organoleptic tests, pH, thickness, folding endurance, and moisture absorption. The results showed that F1 was the optimal formulation, exhibiting favorable physical characteristics and meeting the required standards, as it had the best mechanical properties with higher folding endurance, optimal thickness, and uniform weight distribution, ensuring better flexibility, durability, and stability. These findings indicate that variations in HPMC and PVP concentrations significantly affect the formulation and stability of transdermal patches, with F1 being the most effective formulation for potential wound healing applications.

Abstract

Hydroponics, an emerging agricultural technology, allows cultivation without soil, but using nutrient-rich water instead. This is promising for future agriculture, as it can be applied in various locations and offers higher quality production results, thus increasing market competitiveness. In addition, waste materials such as rice washing water and goat urine can be reused as valuable organic fertilizers. Rice washing water, rich in nutrients such as vitamin B1, phosphorus, calcium, and nitrogen, serves as a liquid organic fertilizer that promotes superior plant growth. Goat urine, containing natural phytohormones, supports root and shoot development, making it a useful alternative to organic fertilizers. Research shows that liquid organic fertilizers are often preferred over synthetic options in hydroponic systems due to their higher bioactive compound content and environmental safety. This study focuses on the cultivation of Pak Choi (Brassica rapa var. Chinensis) using various nutrient treatments, including rice washing water, goat urine, and AB Mix, with measured concentrations ranging from 1000 to 1400 Part Per Millions (PPM). The results showed significant differences in growth among the treatment groups, with AB Mix producing the highest plant height, number of leaves, and leaf width, indicating the effectiveness of nutrient type on plant development.

Abstract

Antibiotic resistance is an increasing global health challenge, especially in patients with advanced chronic kidney disease (CKD). This study aims to investigate cefixime resistance in patients with stage 4-5 CKD at Harapan Keluarga Hospital with a retrospective cohort design using medical record data. Chi-squared test analysis showed a significant association between cefixime resistance and advanced CKD (χ² = 34.714, p = 0.003). The results showed a higher prevalence of cefixime resistance in male patients (60%), antibiotic use of more than 14 days (65%), and hospitalization of more than five days (80%). The mechanism of resistance involves beta-lactamase production and changes in the gut microbiota due to dysbiosis. Factors such as irrational antibiotic use, length of hospital stay, and catheter use contributed to higher resistance. This study highlights the need for evidence-based antibiotic stewardship strategies to reduce resistance, especially in vulnerable populations such as patients with advanced CKD. Scientific implications include the development of more effective infection management strategies, close monitoring of antibiotic use, dose adjustment according to CKD severity, and education of health care workers to increase awareness of antibiotic resistance. This study contributes to efforts to prevent antibiotic resistance in the advanced CKD population.
