Abstract

Tomato (Solanum lycopersicum L.) is one of the vegetable commodities cultivated by farmers in Indonesia and is considered a multifunctional crop. In addition to being consumed as a vegetable, tomatoes are also used as raw materials in the pharmaceutical and cosmetic industries, as well as in food processing. This research was conducted at the Research Field of Pembangunan Panca Budi University, located in Dusun 3, Sampe Cita Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra, at an altitude of approximately 500 meters above sea level. The aim of the study was to determine the effect of cow manure and banana peel liquid organic fertilizer (POC) on the growth and yield of tomato plants. The experiment employed a factorial randomized block design (RBD) with two factors, namely cow manure (K) and banana peel liquid organic fertilizer (C), each replicated three times. Factor I consisted of cow manure application (K) at four levels: K0 = 0 kg/plot, K1 = 1.5 kg/plot, and K2 = 3 kg/plot. Factor II consisted of banana peel POC application (C) at four levels: C0 = 0 ml/L water/plot, C1 = 175 ml/L water/plot, C2 = 350 ml/L water/plot, and C3 = 525 ml/L water/plot. The results showed that the application of cow manure and the concentration of banana peel POC significantly influenced plant height, stem diameter, number of fruits per plot, fruit weight per sample, total fruit weight per plot, and fruit diameter. However, these treatments did not significantly affect flowering time.. Keywords: cow manure fertilizer, banana peel liquid organic fertilizer (POC), tomato

Abstract

This study aimed to evaluate the antifungal activity of eco-enzyme (EE) derived from various horticultural organic wastes against Candida albicans. Two formulations were prepared: Bioz1 (pineapple peel, orange, papaya, starfruit, kuini, and mango) and Bioz2 (pineapple, orange, banana corm, noni, and kuini). Both were fermented for 100 days. The antifungal activity was tested in vitro using the disc diffusion method at concentrations of 1:0, 1:10, 1:50, and 1:100 (EE: distilled water). Results indicated that Bioz1 at 1:50 exhibited the highest inhibition zone (7.38 mm, medium category), while Bioz2 at 1:0 showed the strongest activity (8.16 mm, medium category). Dilution at 1:10 in Bioz2 was the most effective concentration for inhibiting fungal growth. These findings highlight the potential use of eco-enzyme as an environmentally friendly natural disinfectant against pathogenic fungi

Abstract

This research examines the integration of the concept of electrical conductivity in the Measurement and Instrumentation course through a soil fertility monitoring tool. Using a mixed methods approach, the study involved 30 third-year Electrical Engineering students who engaged with a specially designed soil monitoring system as a learning medium and practicum tool. Quantitative analysis showed a significant increase in student understanding, with the mean test score increasing from 42.3 (SD = 8.7) in the pre-test to 78.5 (SD = 9.5) in the post-test (p 0.001, η² = 0.61). Practical skills assessment showed that 83% of students achieved proficiency in tool calibration, while 90% successfully integrated electrical conductivity data with other parameters. Qualitative findings showed an increase in student engagement, with 92% reporting an increase in learning motivation. This implementation resulted in three main outcomes: improved theoretical understanding through hands-on experience, improved technical measurement skills, and the development of an interdisciplinary perspective linking engineering to agricultural applications. The findings suggest that integrating real-world applications into engineering education can significantly improve technical competence and practical skills, providing a model for curriculum development in other engineering disciplines. This study offers valuable insights for engineering educators who want to bridge the gap between theoretical knowledge and practical applications in measurement and instrumentation courses.

Abstract

This study aims to evaluate the potential of eco-enzyme (EE) derived from horticultural waste as an antifungal agent against Candida albicans, a major pathogen responsible for infections in both humans and plants. Eco-enzyme is a product of fermentation that involves using organic waste, such as fruit and vegetable peels, which are often discarded and contribute to environmental pollution. In this research, eco-enzyme was prepared using a variety of horticultural waste, including pineapple, orange, papaya, and mango peels. The eco-enzyme was then tested at various concentrations (1:0, 1:10, 1:50, and 1:100) to assess its antifungal activity against Candida albicans using the in-vitro disk diffusion method. The results indicated that eco-enzyme, particularly at the 1:50 dilution, demonstrated significant antifungal activity, with a clear inhibition zone observed around the disc. The presence of bioactive compounds such as flavonoids, tannins, and saponins in the eco-enzyme is believed to be responsible for its ability to inhibit fungal growth by disrupting the cell membrane structure and metabolic functions of the pathogen. These findings suggest that eco-enzyme can serve as an effective natural alternative to conventional chemical antifungal agents, offering a more sustainable and eco-friendly solution for managing fungal infections. Furthermore, this study emphasizes the importance of utilizing agricultural waste for eco-enzyme production, providing an innovative way to address the global challenge of organic waste disposal while promoting sustainable agricultural practices. The research contributes to the growing body of knowledge on the benefits of eco-enzyme in both agricultural and public health applications, offering promising possibilities for its wider use in fungal disease management

Abstract

This study aims to describe the social order of the community in Gang Musholla Lingkungan Lima, Pekan Subdistrict, Tanjung Morawa District, Deli Serdang Regency, as well as to examine the forms of social interaction, values, norms, and cultural practices that persist in the area. This research employed a descriptive qualitative approach, with data collected through observation, in-depth interviews, and documentation. The research informants consisted of community leaders and the head of the *perwiritan* group residing in Gang Musholla Lingkungan Lima. The findings Indicate that the social structure of the community is still predominantly characterized by strong kinship patterns, while social relations among residents are built upon values of mutual cooperation, tolerance, and social solidarity. Religious activities such as, along with the use of the musholla as a center of social interaction, play an important role in maintaining social norms and fostering collective awareness among community members. However, this study also identifies challenges in the form of value changes resulting from technological development, a decline in the intensity of direct interaction among younger generations, and shifts in the role of community leaders in local decision-making processes. Overall, the social order in Gang Musholla Lingkungan Lima continues to reflect the characteristics of a traditional community with cohesive social patterns, while undergoing a process of social adaptation toward a more modern social structure. This study is expected to serve as a reference for social and community studies and as a basis for the development of locally based community empowerment programs.

Abstract

Ecoenzyme perfectly utilizes biological waste for non-chemical sanitation products through the fermentation of sugar, organic materials, and water. Ecoenzyme has been used to inhibit the growth of bacteria such as Staphylococcus aureus and Propionibacterium acnes. This study aims to determine the optimum concentration of eco enzyme as a natural antibacterial and disinfectant. This method uses gram-positive bacteria Staphylococcus aureus and gram-negative bacteria Escherichia Coli with the disc method. The dilution variations used were 0, 1:10, 1:50, and 1:100. Ecoenzyme is made from organic materials from pineapple, orange, papaya, starfruit, quinine, and mango skin waste (Bioz1), and coenzyme from pineapple, orange, banana stem, noni, quinine waste (Bioz2). The results showed that a ratio of 1:10 was the most effective dilution variation for inhibition against both types of bacteria. Furthermore, dilution at this concentration can be used as a natural disinfectant. The presence of acetic acid and enzymes (i.e. lipase and amylase) can inhibit certain strains of microorganisms, namely Escherichia coli and Enterococcus sp.
