Abstract

Abstrak. Beton prategang merupakan beton yang menerima tengangan internal berupa tegangan tekan awal yang diakibatkan oleh gabungan tendon yang ditarik dahulu sebelum menerima beban untuk mengimbangi tegangan yang terjadi akibat beban eksternal, dimana proses pemberian tegangan dilakukan sebelum beton dicetak (pratarik) atau setelah beton dicetak (pascatarik). Tegangan yang diberikan dapat dilakukan dengan dua metode, yaitu metode stressing satu arah dan stressing dua arah. Pemberian tegangan dengan kedua metode stressing mengakibatkan kehilangan gaya prategang. Tujuan dari penelitian adalah untuk mengetahui besar kehilangan prategang agar dapat memprediksi kehilangan prategang jangka panjang guna mengestimasi besarnya lawan lendut. Analisis yang dilakukan yaitu dengan menghitung gaya prategang, menentukan jumlah dan lintasan tendon, menghitung kehilangan prategang metode stressing satu arah dan dua arah, menghitung kontrol tegangan dan lendutan pada girder. Jenis girder yang digunakan pada perhitungan ini adalah PC I Girder. Dari hasil analisis didapatkan hasil kehilangan prategang metode stressing satu arah pada PC I girder sebesar 24,40 persen, dan kehilangan prategang metode stressing dua arah (ditarik bergantian) sebesar 24,12 persen dan metode stressing dua arah (ditarik bersamaan) sebesar 20,76 persen.Dari hasil tersebut, dapat disimpulkan bahwa kehilangan prategang dengan menggunakan metode stressing dua arah khususnya yang ditarik bersamaan lebih kecil dibandingkan dengan metode stressing satu arah.  Kata kunci : beton prategang, metode stressing, satu arah, dua  arah

Abstract

The procurement of goods and services was previously conducted manually or conventionally. Presidential Regulation No. 54 of 2010, which replaced Presidential Decree No. 80 of 2003, formally contained the objective of e-procurement in the procurement of government goods/services for the first time. Neither the committee nor the providers of goods/services readily accepted the newly implemented system. The success of the e-procurement program is highly determined by the human factor. User readiness to accept the technology is the key to successful implementation, because their response will determine whether this technology succeeds or fails. This study uses mixed methods and aims to obtain empirical evidence about the influence of human resource competence, infrastructure, and supervision factors in the implementation of the e-Procurement system, as well as to provide strategic recommendations for improving the implementation of the e-Procurement system in Ngada Regency. The research sample consisted of 39 employees of the Goods and Services Procurement Section of Ngada Regency, selected using the saturated sampling technique within the nonprobability sampling method. Data was collected through questionnaire surveys and interviews, then analyzed using Smart Partial Least Square 3.2. The results of this study revealed that human resource competence, infrastructure, and supervision have a significant influence on the implementation of the e-Procurement system in Ngada Regency. Improvement in these three factors can enhance the success of the e-Procurement system implementation. Some recommended strategies to improve the implementation of the e-Procurement system are to conduct education and training, provide internet networks and backup servers through the Department of Information and Communication, carry out socialization to involve the public in monitoring, increase evaluation transparency by adding an evaluation column on the Electronic Procurement Institution (LPSE) website, conduct routine audits, and issue regulations regarding the implementation of e-audit in the process of procuring goods/services.
