Abstract

Physical inspections of construction are the result of follow-up activities from document analysis conducted by the relevant parties, where weaknesses in the reporting of audit results or physical inspections of construction are identified. The physical inspection of construction also seeks significant issues due to differences in interpretation regarding the calculation of work volume during the tender process and the evaluation of work progress. Community Service Activities (PKM) are one of the Tri Dharma of Higher Education, alongside education, teaching, and research. Through this activity, it is hoped that the target community can obtain useful information and then apply and further develop the information provided by the speakers. The implementation method is carried out in two ways: desk audits and direct field inspections. Preliminary surveys/desk audits are conducted on the packages being examined, in accordance with the Work Order, aimed at detecting potential early deviations in the implementation of the packages to be examined. The results of the community service indicate the need for learning development activities through collaborative or community service initiatives aimed at providing assistance in line with the area of expertise. The results of this service also provide recommendations and analyses from experts that are useful for maintaining orderly public financial administration in its usage, thereby allowing for the anticipation of irresponsible parties. The assistance in community service activities also imparts specific knowledge to students regarding the direct application of scientific knowledge. The objective of the construction inspection is to ensure the orderly execution and results of construction work, covering physical aspects including volume and quantity of construction, planning, procurement, management of implementation, and contract control in building construction projects. Therefore, the implementation of PKM provides a supportive solution in the physical inspection of items related to building construction.

Abstract

Sifat lumpur beton dapat mengurangi kekuatan. Kadar lumpur pasir dicuci turun sebesar 2,9 persen setelah diperiksa. Oleh karena itu, pasir yang telah dicuci memenuhi standar kadar lumpur yang diizinkan. Bahan yang diperlukan: Sampel silinder pasir yang dicuci dan tidak dicuci dari JMF mutu beton rencana K-250 dengan umur 21 hari. Untuk 1 m3 diperlukan 430,23 kg semen, 633,59 kg pasir, 1.151,18 kg kerikil, dan 185 liter air. Pasir dicuci memiliki kekuatan tekan 273,67 kg/cm2, sedangkan pasir tidak dicuci mengalami penurunan kekuatan tekan 208,54 kg/cm2. Pasir yang tidak dicuci dapat menurunkan kekuatan tekan beton dibandingkan dengan rencana. Diharapkan pelaksana lapangan mencuci pasir sebelum using pasir sebagai campuran untuk mencapai mutu beton yang direncanakan.
