Abstract

The Samal Kanan Irrigation Area in Central Maluku Regency, which has been operating since 2003, has experienced a decline in physical condition, particularly in the Morokai Secondary Canal. This study aims to evaluate the performance and physical infrastructure condition of the canal to determine the functional level of the irrigation system. The research employed a quantitative approach, with data collected through field surveys and discharge measurements and subsequently analyzed based on the guidelines stipulated in the Minister of Public Works and Public Housing Regulation Number 12/PRT/M/2015. The results indicate significant physical damage, including cracks, wall fractures, sedimentation, and vegetation that obstruct water flow. The measured discharge of 0.145 m³/s is lower than the design discharge of 0.594 m³/s. The Irrigation System Performance Index (ISPI) value of 58.2% falls into the poor category, indicating the need for major rehabilitation with an estimated cost of IDR 656,349,000 for a canal length of 525.36 meters. Keywords: canal discharge measurement, irrigation system performance index, Morokai Secondary Canal.

Abstract

In Construction Project Management studies, it is essential to analyze and assess the stability and strength of building structures to determine their ability to resist applied loads. In the construction project of the Integrated Educational Building of IAIN Ambon, several structural elements were found not to meet the applicable standards. Therefore, the objective of this study is to design and redesign the dimensions and reinforcement system of the superstructure of the Integrated Educational Building of IAIN Ambon in accordance with the standards. The analysis was conducted using the Limit Strength Method in combination with SAP2000 v.25 to evaluate the safety and serviceability of the structure. The results of the study show that the dimensions of beams and columns meet the requirements of SNI 2847:2019, with dimensions of Beam B1: 750×350 mm, Beam B2: 650×350 mm, and Beam B3: 500×300 mm. Meanwhile, the slab with a thickness of 130 mm was deemed inadequate and replaced with a thickness of 200 mm. Based on the analysis results, the designed reinforcement system satisfies both strength and geometric requirements, ensuring safety and compliance with SNI 2847:2019. Keywords: Superstructure, Limit Strength Method, SAP2000, Safety, Design.
