Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dari bata ringan berbahan dasar limbah bata merah yang digunakan sebagai bahan tambah terhadap kuat tekan bata ringan CLC. Bata merah yang digunakan yaitu berupa bubuk lolos saringan no. 100. Penelitian ini dilakukan dengan metode eksperimental yang dilakukakan di laboratorium. Pada penelitian ini digunakan penggunaan bubuk bata merah dengan variasi 0%, 1%, 2%, 3%, 4% dan 5%. Jumlah benda uji yang dibuat sebanyak 54 sampel menggunakan cetakan kubus dimensi 15 x 15 x 15 cm dan pengujian kuat tekan dilakukan pada umur 7 hari, 14 hari, dan 28 hari. Hasil dari penelitian ini didapatkan bahwa penambahan bubuk bata ringan dengan variasi 2%, 3%, 4% dan 5% mampu meningkatkan kuat tekan bata ringan CLC dibadingkan dengan bata ringan 0% sebagai bata pembanding. Kuat tekan tertinggi pada umur 28 hari terpada pada variasi 2% yaitu sebesar 2.94 MPa dan kuat tekan terendah terdapat pada variasi 1% yaitu sebesar 1.97 MPa. Hasil tersebut menunjukan bahwa penggunaan bubuk bata merah dapat dijadikan bahan tambah alternatif yang ramah lingkungan dan ekonomis untuk meningkatkan kuat tekan bata ringan CLC.

Abstract

Along with the development of construction projects, many tools have been created and developed to assist and facilitate activities in construction projects. In carrying out the selection of tools, it is very necessary to plan properly and carefully according to the conditions of the project and the ability of the workers. One tool that is generally used in projects for tall buildings is the piling tool for working on the foundation. In the construction project of SMAN 14 Samarinda, the rigging tools are used, namely drop hammer and jack in pile. This study discusses productivity and several strategies to increase the duration of pile equipment. The data used is obtained from the project in the form of pile tool cycle time data. From the analysis it is known that the average productivity value of the jack in pile is 2.19 and the drop hammer is 1.20. From this productivity, the jack in pile is more efficient than the drop hammer. The use of a drop hammer was chosen because it is relatively inexpensive and the jack in pile was chosen because this method uses static pressure without causing negative impacts (noise and vibration) to the residents around the project. The piling tools used must prioritize the economic value aspects and without negative impact on the community.
