Abstract

Pembangunan dalam bidang konstruksi semakin berkembang, terutama dari segi desain maupun metode pelaksanaannya. Pembangunan bidang konstruksi menghasilkan produktivitas yang berbeda, sehingga berpengaruh terhadap mutu, waktu dan biaya pelaksanaan, maka dalam pelaksanaan dilakukan secara efisien dan efektif. Dalam pelaksanaan struktur beton ada beberapa metode yang dipakai salah satunya adalah metode konvensional yaitu dilakukan langsung di lokasi. Pembangunan Villa Guilherme Berawa, Canggu menggunakan metode konvensional, terjadi beberapa masalah yaitu dari segi waktu terjadi keterlambatan, dan dari segi tempat memerlukan lokasi penyimpanan material yang luas. Terjadinya permasalahan yang timbul di lapangan, maka dicoba alternatif yaitu metode ready mix. Dari segi waktu pelaksanaan ready mix lebih cepat, dan dari segi lokasi tidak kesulitan menempatkan material. Dari segi sumber daya tidak membutuhkan sumber daya yang banyak. Tujuan dari penelitian ini adalah untuk menganalisis perbandingan dari segi biaya dan waktu pelaksanaan pengecoran konvensional dengan ready mix khususnya pada pekerjaan beton balok dan pelat lantai dua. Diperlukan analisis untuk mengetahui tingkat efisiensi dan efektifitas antara kedua metode ini. Hasil penelitian menunjukkan metode konvensional memerlukan biaya sebesar Rp. 158.728.450,00 dengan waktu pelaksanaan 8 hari, sedangkan metode ready mix sebesar Rp. 186.606.936,00 dengan waktu pelaksanaan hanya 1 hari. Selisih biaya antara kedua metode adalah Rp 27.878.486,00 yaitu ready mix lebih mahal sekitar 17,6 %. Perbedaan waktu sangat signifikan, ready mix mampu mempercepat proses pekerjaan hingga 7 hari. Dari sisi biaya metode konvensional terbukti lebih ekonomis, namun dari sisi waktu metode ready mix jauh lebih efisien.

Abstract

The construction of the SMP Negeri 16 Denpasar building is located at Jalan Kertha Winangun No. 1 in Sidakarya Village, South Denpasar. The purpose of this study is to identify and evaluate the risks associated with the construction of the SMP Negeri 16 Denpasar building. This study uses a qualitative descriptive method, namely field research that uses data and information obtained through respondents as subjects to obtain holistic general picture answers regarding the matters studied. Risk identification is obtained through interviews and surveys to obtain possible risks that will occur in the construction of the SMP Negeri 16 Denpasar building. The results of the study showed that the identified risks were 32 (thirty-two) risks, namely 8 environmental risks (25%), 2 planning risks (6.3%), 2 economic risks (6.3%), financial risks (6.3%), natural risks (6.3%), 4 project risks (12.5%), technical risks (21.9%), human risks (3.1%), criminal risks (6.3%), and safety risks (6.3%). The results of the analysis of the level of risk acceptance showed that there were 2 risks (6%) included in the unacceptable category, 18 risks (56%) included in the undesirable category, 9 risks (28%) included in the acceptable category and 3 risks (10%) included in the negligible category.

Abstract

Structural work, especially in the casting process, plays an important role. One of the methods that can be used is casting with ready mix concrete, because of the better time efficiency than conventional methods. The purpose of this study is to find out about the stages, specifications and technical requirements on the 2nd floor plate. A case study on the construction of the Tabanan Public Service Mall located in Banjar Anyar, Kediri District, Tabanan Regency. The research method used is a quantitative method, the data used is the Cost Budget Plan (RAB) analyzed to obtain the description of the work and volume, the plan drawing is used for the creation of work drawings, the time schedule is used as a reference in the duration of the work, the Unit Price Analysis of Work is used to obtain the resource coefficient and resource price. From the job description data, the stages of the activity are obtained, the plan drawings produce work drawings, and the time schedule produces the duration of the work. The results of the study obtained that in the stages of casting work with ready mix on the 2nd floor plate in scaffolding work there are 5 stages of activities, bodeman work 3 stages of activities, B1 beam formwork 30 x 50 cm and B2 beam formwork 25 x 35 cm there are 4 stages of activities, B1 beam and B2 beam ironing work there are 3 stages of activities,  Formwork with bondek plates has 5 stages of activities, wiremesh  ironing work has 3 stages of activities, casting work with ready mix on the 2nd floor plate has 3 stages of activities.
