Abstract

The mold Aspergillus flavus produces a metabolite molecule called aflatoxin. Aflatoxin chemicals can have harmful effects on both humans and livestock when they are present in feed ingredients. Aspergillus flavus frequently grows on corn, one of the feed ingredients. Examining the amount of aflatoxin contamination in corn in North Lombok Regency and how it affects laying hen performance was the goal of this study. Random sampling was done from each subdistrict, and descriptive analysis was done on the collected data. According to the study's findings, aflatoxin compounds, which have a range of 87.99–132.38, were found in 50% of corn. Aflatoxin concentration in feed surpasses the 60 ppm SNI guideline by 33.33%.  Performance is impacted by aflatoxin compounds in maize; specifically, 50% of feed intake, 50% of egg weight, and 100% of noncompliance with SNI and corporate criteria are not met. The results of this study suggest that aflatoxin levels in diet have an impact on laying hens' declining performance.

Abstract

Honeybees (Apis cerana) are one of the indigenous honeybee species of Asia. They serve a crucial function in ecosystems, mostly as pollinators. This study investigates the morphometric characteristics of Apis cerana worker bees in North Lombok Regency, focusing on two beekeeping groups: Harapan Keluarga and Tunas Muda, located in Salut village, Kayangan District North Lombok Regency. Morphometric analysis was conducted on 40 colonies, with measurements taken from eight key body traits: body length, abdomen length, femur length, tibia length, metatarsus length, forewing length, hindwing length, and body weight. Results revealed significant differences between the two locations. Tunas Muda bees exhibited larger morphometric traits with lower coefficient variations, indicating higher population uniformity. Correlation and regression analyses showed that body length, forewing length, and abdomen length strongly influence body weight, with body length having the highest correlation (r = 0.85) and determination coefficient (R2 = 0.722). The study highlights the impact of environmental factors, management practices, and nutritional conditions on bee morphology. These findings provide critical insights for enhancing beekeeping practices, supporting honeybee conservation efforts, and exploring genetic and physiological adaptations in Apis cerana. This research underscores the importance of integrating morphometric analysis into sustainable apiculture and biodiversity conservation strategies in North Lombok.

Abstract

Honey is known to contain several chemical compounds that have functions as an antibacterial, anti-inflammatory, wound healing, anticancer, and antioxidant. Honey has antibacterial effectiveness against S. aureus, S. typhi, and E. coli bacteria and has high antioxidant levels. This study focused on exploring the antibacterial and antioxidant activity of Trigona sp honey cultivated in North Lombok Regency, NTB, and Apis cerana and Apis dorsata honey as comparisons. The results showed that the three types of honey had antibacterial activity by forming various inhibition zones. These results also show that Trigona, A. cerana and A. dorsata honey are very potential to be consumed for various purposes, especially to improve health and immunity during the Covid-19 pandemic.

Abstract

The Merak Ferry Port is a major ferry transportation route in Indonesia, serving the Merak-Bakauheni crossing. Based on observations and analysis, several issues were identified related to the zoning system and vehicle traffic flow patterns in 2023, such as the combination of executive and regular vehicle lanes in a single service, limited parking capacity, and the presence of crossings between vehicles that hamper the smooth loading and unloading process. This study aims to analyze and compare the zoning system and traffic flow patterns at the Merak Ferry Port in 2023 and 2025 to evaluate the effectiveness of the changes made. This study employed a qualitative descriptive method, with data collection techniques through field observation and analysis of official documents. The results indicate that changes to the 2025 zoning system, including the separation of executive and regular vehicle lanes and the addition of ready-to-load parking capacity, have a positive impact on the smooth flow of vehicles and the effectiveness of space management. Overall, these zoning changes have successfully improved the existing system and increased operational efficiency and service quality at the Merak Ferry Port.
