Abstract

Ipomoea reptans P. commonly known as water spinach, is a leafy vegetable with high economic value and is widely consumed by the Indonesian population. This plant is extensively cultivated due to its short harvest cycle of approximately 25–30 days after planting, which provides farmers with the opportunity to increase land productivity. This study was conducted on agricultural land at the Universitas Pembinaan Masyarakat Indonesia (UPMI), Medan, from June to August 2025. A factorial Randomized Block Design (RBD) 4×4 with three replications was employed. The first factor was the Auxin Plant Growth Regulator (PGR) with four levels: Z0 = control, Z1 = 50 ml/L, Z2 = 100 ml/L, and Z3 = 150 ml/L. The second factor was POC PSB with four levels: P0 = control, P1 = 50 ml/L, P2 = 100 ml/L, and P3 = 150 ml/L. The results indicated that the application of Auxin PGR significantly affected the production parameters, with treatment P2 (100 ml/L) yielding a fresh weight of 58.1 grams. Furthermore, the interaction between Auxin PGR and POC PSB had a highly significant effect on the fresh weight of plants. The optimal combination was found in treatment Z3P2 (150 ml/L Auxin + 100 ml/L POC PSB), resulting in a fresh weight of 65.7 grams. In conclusion, the combined application of 150 ml/L Auxin PGR and 100 ml/L POC PSB significantly enhances the growth and yield of Ipomoea reptans and represents an environmentally friendly alternative technology to improve horticultural productivity. Keywords: ipomoea reptans, auxin plant growth regulator, POC PSB, growth, yield

Abstract

This study aimed to evaluate the effect of coconut water seed soaking duration and flash fertilizer application on the growth and yield of mung bean (Vigna radiata L.). The experiment was conducted at the experimental field of the Faculty of Agriculture, Indonesian Community Development University, Medan, from May to August 2024. A Randomized Block Design (RBD) with two factors and three replications was employed. The first factor was coconut water soaking duration (0, 2, 4, and 6 hours), while the second factor was flash fertilizer application (0, 0.25, 0.5, and 1 cc/L). Observed parameters included plant height, number of leaves, flowering age, pod weight per plant, and pod weight per plot. Results indicated that a soaking duration of 6 hours (P3) had a highly significant effect on all observed parameters, producing the highest plant height, leaf number, and pod weight. Similarly, flash fertilizer at 1 cc/L (K3) promoted better vegetative and reproductive growth compared to other treatments. The interaction of P3K3 produced the best performance across growth and yield traits. These findings suggest that combining coconut water seed soaking for 6 hours with flash fertilizer application at 1 cc/L is an effective strategy to enhance mung bean productivity. Keywords: mung bean, coconut water, flash fertilizer, growth, yield

Abstract

This study aimed to determine the effect of applying Jadam Microbial Solution (JMS) and liquid NPK fertilizer, both factorially and in combination, on the growth of mustard greens (Brassica juncea L.). The experiment was carried out using a factorial Randomized Block Design (RBD) consisting of two factors. The first factor was JMS application with four levels (J0 = 0 ml/l water, J1 = 100 ml/l water, J2 = 200 ml/l water, J3 = 300 ml/l water), and the second factor was liquid NPK fertilizer with four levels (N0 = 0 ml/l water, N1 = 10 ml/l water, N2 = 15 ml/l water, N3 = 20 ml/l water). Each treatment combination was repeated three times, resulting in 16 treatment combinations. The results showed that JMS application had a significant effect on plant height and number of leaves at all observation times (7, 14, and 21 days after planting/DAP), indicating improved vegetative growth and yield. Liquid NPK fertilizer application also significantly affected plant height and number of leaves at all observation times. The combination of JMS and liquid NPK fertilizer had no significant effect during the early growth stage (7 DAP), but showed significant effects on plant height and number of leaves at 14 and 21 DAP. These findings indicate that factorial application of JMS and liquid NPK fertilizer can enhance the growth of mustard greens, while their combination is effective at certain vegetative growth stages. Keywords: Brassica juncea L., jadam microbial solution, liquid NPK

Abstract

Nurse managers play an essential role in coordinating emergency department functions, especially during global health crises such as the COVID-19 pandemic. In low- and middle-income countries (LMICs), including Indonesia, their experiences have not been widely explored, despite facing unique logistical, emotional, and cultural challenges. This study aims to explore the lived experiences of nurse managers in overseeing COVID-19 screening procedures in the emergency department of RSUP H. Adam Malik Hospital in Medan, Indonesia. A descriptive phenomenological approach was employed to capture the essence of their experiences. Ten nurse managers were selected using purposive sampling. Data were collected through semi-structured interviews lasting 30 to 60 minutes, supplemented by field notes and document analysis. Colaizzi's seven-step method guided the analysis, with credibility ensured via member checking and triangulation using multiple informants. The study identified five major themes: (1) psychological distress in the early phase of the pandemic, stemming from fear, uncertainty, and concern for family safety; (2) challenges in implementing screening, including patient resistance, resource limitations, and PPE shortages; (3) proactive efforts for early COVID-19 detection through triage protocols and symptom-checking tools; (4) improvements in screening management, emphasizing leadership, education, and compliance; and (5) adaptation and resilience, as nurse managers developed strategies to cope with evolving demands and pressures. These themes reveal both universal healthcare struggles and context-specific issues-such as anxiety about infecting multigenerational households-that shaped nurse managers' responses. This research contributes to the limited body of qualitative evidence on pandemic leadership in LMICs. The insights gained underscore the importance of robust emergency preparedness, targeted psychological support for healthcare leaders, and ongoing improvements in screening protocols. Strengthening these areas can better equip healthcare systems to face future public health emergencies. Keywords: Nurse Managers, COVID-19, Emergency Department, Screening, Indonesia, LMICs.

Abstract

Global agriculture faces significant threats from climate change and soil degradation, with approximately 66.49% of Indonesian agricultural land currently categorized as unsustainable. This study analyzes the impact of regenerative agriculture practices on soil health indicators and agribusiness profitability within Indonesian farming systems. Using a mixed-methods research design, data were collected from smallholder farmers in Deli Serdang Regency, North Sumatra Province, Indonesia, comparing those adopting regenerative techniques against those using conventional methods. The study concludes that regenerative agriculture serves as a viable win-win strategy for Indonesian smallholders, offering a pathway to restore degraded ecosystems while enhancing economic resilience through cost-efficiency. Policymakers are encouraged to integrate these practices into national development strategies to support Indonesia’s 2045 food self-sufficiency targets.
