Abstract

Implementing an organic waste management program is a crucial step in realizing a sustainable campus. Organic waste management such as yard waste management program in Sam Ratulangi University, Manado, is crucial to maintaining a sustainable environment. The university's efforts to implement sustainable waste management practices, such as recycling and create an alternative energy sources like biodigester, have significantly reduced the amount of waste sent to landfills and creates valuable resources such as heat and liquid organic fertilizer. The application of liquid organic fertilizer from a biodigester on the university's green house resulted in an increased Pakcoy growth parameters and productions. By using liquid organic fertilizer from a biodigester is a sustainable and effective way to fertilize green areas at Sam Ratulangi University. By implementing this practice, the university can reduce waste and support healthy plant growth while also promoting environmental stewardship.

Abstract

An essential stage in road infrastructure development is land acquisition, which frequently causes project delays due to its complex legal, social, and economic challenges. This study aims to identify the factors that hinder the land acquisition process in the Manado Outer Ring Road (MORR) 3 Phase 4 Construction Project and to assess how these constraints affect the progress of construction activities. The research was conducted using a qualitative case study approach, with data collected through field observations, document reviews, and interviews. The findings indicate that delays in land acquisition are caused by discrepancies in legal status and land ownership, differing perceptions of compensation value, insufficient public socialization, and weak institutional coordination. These issues lead to disruptions in the construction schedule and potential increases in project costs. The study demonstrates that land acquisition necessitates a more cohesive strategy, facilitated by enhanced communication and community engagement, fortified land acquisition management frameworks, and precise verification of ownership data. The results indicate that there must be broader mitigation strategies to prevent similar challenges in future infrastructure projects.

Abstract

This study evaluates the implementation of spot-check testing for road preservation works in Manado City, specifically on the Kairagi–Mapanget segment, the Manado City–Wori boundary, and the Liwas Terminal Access Road, to identify existing problems and assess the effectiveness of engineering-based mitigation efforts. The objective is to examine construction quality compliance with technical specifications and identify operational challenges encountered on site. The methodology encompasses the measurement of asphalt layer thickness and density via a core drill, the examination of contract documents, the analysis of laboratory test results, and the execution of field observations. The findings show that most samples meet the required standards, although several locations require corrective action. Challenges arise from weather conditions, heavy traffic, equipment limitations, and the need for adaptation to updated technical regulations. Operational mitigation strategies, staff training, the use of core drill technology, and digital documentation were found to enhance accuracy and efficiency in evaluation. The research demonstrates the value of stakeholder collaboration and capacity building in supporting quality control for road preservation works. A multidimensional approach is effective in resolving technical and operational complexities in urban road projects.
