Abstract

Competition in the tour agent business is increasing in the digital era, especially to increase sales figures. The use of content marketing strategies is carried out to build brand awareness in the customer path process. This research aims to test the influence of brand awareness through content marketing in implementing customer path 5A at the Doctor Trip Indonesia tour agent. Doctor Trip Indonesia is a company that has only been established for 3 years. This research uses quantitative methods by conducting a survey of 190 respondents. The population in this research are consumers who have made a purchase at least once. This research uses accidental sampling with purposive sampling technique. Data collection was carried out from March to April 2024, and processed using the Structural Equation Model Partial-Least Square (SEM-PLS). The research results show that brand awareness through content marketing has a positive and significant effect on customer path 5A. It is hoped that the results of this research can be a reference for managers in determining strategies to increase the effectiveness of content marketing in building brand awareness until it reaches the final level of customer path 5A.

Abstract

This study aims to analyze the workload of frontliner employees at Bank X and determine the optimal number of employees to enhance operational efficiency. The methods employed include work sampling and full-time equivalent (FTE). The results indicate that productive activities in the frontliner division accounted for 77.80%, non-productive activities 11.59%, and personal activities 10.61%. FTE analysis revealed that 2 employees had normal workloads, while 4 others experienced overload. Based on these findings, additional employees are required to balance workloads, bringing the ideal total workforce to 12 employees. This study provides essential recommendations for optimizing human resource planning at Bank

Abstract

Kepundung is a local fruit that grows almost on all island in Indonesia, the used of kepundung can be processed into fruit syrup. This research aims to determine the effect of temperature and cooking time on the physical stability and quality of kepundung syrup. This research began by making syrup made from kepundung fruit. The method used in this research is a factorial Completely Randomized Design method with two factors, that is cooking temperature (A): (80°C, 90°C, and 100°C) and cooking time (B): (20, 30, and 40 minute). The parameters tested in this research were color index stability (°Hue), pH, viscosity, organoleptic testing for 8 weeks, and thermal degradation kinetics. The results of the research showed that cooking temperature had a very significantly different effect (P<0.01) on the stability of the color index, pH, and viscosity. The best treatment for kepundung syrup is A3B3 (temperature 100°C and cooking time 40 minutes). Based on the determination of the kinetic ordo of thermal degradation, the color index R2 is closest to 1 at ordo 0 and in the calculation of Ea, ordo 0 is chosen with smaller Ea value. Based on determining ordo of thermal degradation kinetics, pH R2 closest to 1 at ordo 0 and in the calculation of Ea, ordo 1 is chosen with smaller Ea. Based on determining ordo of thermal degradation viscosity R2 is closest to 1 at ordo 1 and in the calculation of Ea, ordo 0 is chosen with smaller Ea

Abstract

Biofertilizer is considered an alternative to chemical fertilizers for enhancing plant productivity while minimizing ecological damage. Endophytic bacteria have the ability to solubilize phosphate and produce IAA (indole acetic acid). The aim of this research is to assess the phosphate solubilization and IAA production abilities of bacterial isolates applied to chili plants. Seven bacterial isolates collection from the Microbiology Laboratory, Universitas Sumatera Utara, were tested. In quantitative tests conducted in vitro, isolates MB10 and MB11 demonstrated the highest phosphate solubilization capabilities, yielding solubilization indices of 16.2 mm and 9.5 mm, respectively. Additionally, the ability of bacterial isolates to produce IAA in vitro was evaluated using calorimetry, revealing that isolates MB8 and MB2 produced the highest concentrations of IAA, measuring 58.58 ppm and 54.64 ppm, respectively. Furthermore, in vivo application involved the inoculation of isolates MB10 and MB11 on chili plants for 30 days. Seed treatment with suspensions of isolates MB10 and MB11 resulted in decreased plant performance compared to the control. These findings indicate that some endophytic bacteria originating from the mangrove root Avicennia marina have potential for producing relatively high levels of secondary metabolites. However, direct application did not significantly enhance plant growth performance.

Abstract

This study aimed to isolate and morphologically characterize fungi from the mangrove area of Belawan, North Sumatra, to better understand their diversity and potential roles within the ecosystem. Mangrove forests are vital coastal ecosystems that support diverse microbial communities, including fungi, which play essential roles in nutrient cycling and ecosystem stability. This study aimed to isolate and characterize fungal diversity from the Belawan mangrove area, North Sumatra. Sampling was conducted on water and soil, followed by fungal isolation on Potato Dextrose Agar containing 1% NaCl. A total of 15 fungal isolates were obtained—nine from water and six from soil samples. Morphological characterization revealed considerable diversity in colony shape (circular, irregular, filamentous), texture (granular, cottony, velvety), margin (undulate, filiform, entire), and color (green, white, pink, grayish white, black, dark brown). Microscopic examination showed various conidial morphologies, including round conidia that burst open like fans, crescent-shaped conidia, needle-shaped conidia with branched conidiophores, and conidia arranged in chains on phialides. The dominant genus identified was Aspergillus, exhibiting typical macroscopic and microscopic traits. Physical-chemical parameters of the sampling sites indicated stable environmental conditions suitable for mangrove fungi. This study highlights the rich fungal diversity in the Belawan mangrove ecosystem and underscores the ecological importance of fungi in maintaining mangrove health. The results provide a foundation for further molecular identification and exploration of the biotechnological potential of mangrove-associated fungi.

Abstract

This study aims to isolate and characterize the morphological characteristics of fungal colonies obtained from leachate water at a landfill site. To obtain fungi from leachate water, the following steps were taken: Fungi were isolated using the pour plate method with Potato Dextrose Agar (PDA) medium; morphological characterization of fungi was performed macroscopically and microscopically. Macroscopically, by observing the shape, edges, texture, and color of the fungal colonies, and microscopically, by observing the shape of the hyphae and the presence of asexual spores. The results showed that seventeen fungal isolates were successfully isolated from the leachate of the Namo Bintang landfill with different morphologies. The macroscopic characteristics of the fungal colonies showed that 15 fungal isolates had round colonies, and the other two isolates (NKD 07 and NKT 14) had irregular colonies. The edges of the fungal colonies varied, ranging from flat, wavy, to serrated. The color of the fungal colonies was predominantly gray and green. The texture of the fungal colonies varied from powdery, hairy, smooth, to cotton-like. Microscopic characteristics of the fungi show that most fungal isolates have septate hyphae and varied conidia shapes, such as round, oval, crescent, and tubular. These findings indicate that the leachate from the Namo Bintang landfill contains diverse fungi with different colony morphological characteristics, making it possible to develop them as biological agents.
