Abstract

The poultry industry has experienced significant transformation driven by innovations in housing systems aimed at improving productivity and animal welfare. This study focuses on the integration of colony cage systems with tunnel ventilation and automatic feeding technologies as a comprehensive approach to optimize laying hen performance. The objective is to review existing literature to assess the impacts of these innovations on productivity indicatorssuch as egg production rate, feed conversion ratio, and resource efficiencyand on health outcomes including stress markers, plumage condition, and mortality rates. A qualitative literature review method was applied, synthesizing data from peer-reviewed journals, conference proceedings, and credible academic sources published between 2020 and 2025. Content analysis was employed to categorize findings into themes of productivity, health, feed efficiency, and welfare. Results indicate that colony cage systems enriched with perches and nesting areas allow hens to perform natural behaviors while maintaining production efficiency. Tunnel ventilation contributes to environmental stability, reducing heat stress and supporting consistent feed intake, whereas automatic feeding systems minimize feed wastage, ensure precise ration delivery, and lower stress associated with competition. When integrated, these technologies synergistically improve egg production rates, enhance feed efficiency, reduce stress markers, and decrease mortality. Nevertheless, outcomes remain highly dependent on system design, strain adaptation, and management practices. Overall, integrated colony cage systems with tunnel ventilation and automated feeding offer a promising direction for sustainable and welfare-oriented poultry farming.

Abstract

Delays and cost deviations remain common challenges in construction projects, particularly in government-funded projects where administrative and regulatory dynamics can influence implementation. This study aims to evaluate the time and cost performance of the construction of the Social Service Building of East Nusa Tenggara Province using the Earned Value Management (EVM) method integrated with Microsoft Project. The research employed a quantitative descriptive approach based on primary data from weekly progress reports and field observations, as well as secondary data such as the S-curve, Work Plan and Requirements (RKS), and unit price analyses. A total of 1,200 project activities were reconstructed in Microsoft Project to develop detailed scheduling, resource assignments, baseline estimation, and performance tracking. The results indicate that the project experienced significant delays at Week 34, with a Schedule Variance of –54.87% and a Schedule Performance Index of 0.45. However, the project remained under budget, reflected by a Cost Variance of 0.64% and a Cost Performance Index of 1.01. Projection analysis estimates that the project will be completed in Week 76, indicating substantial schedule slippage, although the cost at completion is predicted to remain below the original budget.
