Abstract

Jembatan tipe slab on pile umumnya terdiri dari dua bentang atau lebih. Sampai saat ini belum ada ketentuan atau pedoman terkait dengan panjang bentang terkecil dan terbesar. Dengan demikian penentuan panjang bentang jembatan slab on pile lebih kepada engineering judgment desainer dan/atau pemilik jembatan. Penelitian ini mencoba menentukan panjang bentang optimal yang dapat menghasilkan biaya konstruksi bangunan atas yang minimal dalam satuan rupiah per satuan luas jembatan slab on pile di daerah tanah lunak. Adapun lokasi penelitian berada di Jembatan Ray 2 Kabupaten Barito Kuala. Dalam penelitian ini, jembatan dibagi kedalam tiga tipe, yaitu Tipe I dengan bentang segmental 4 m dengan banyak bentang lima bentang dan panjang bentang total 20 m, Tipe II dengan bentang segmental 5 m dengan banyak bentang empat bentang dan panjang bentang total 20 m, dan Tipe III dengan bentang segmental 7 m dengan banyak bentang tiga bentang dan panjang bentang total 21 m. Berdasarkan hasil desain, biaya konstruksi bangunan atas per satuan luas untuk untuk jembatan slab on pile tipe I sebesar Rp5,795,673.4, jembatan slab on pile tipe II sebesar Rp5,313,707.8, dan jembatan slab on pile tipe III sebesar Rp4,925,033.0. Perbedaan biaya konstruksi ini dipengaruhi oleh jumlah pier head yang dimiliki jembatan, dimana tipe III memiliki jumlah pier head terkecil Abstract Slab on pile bridges consist of two spans or more. Until now, there are not codes state cleary about shortest and largest span of slab on pile bridge. Therefore, decision about length of span tends to engineering judgement of designer and/or owner of the bridge. This research tries to propose about optimal span that obtain a minimal construction cost of superstructure of slab on pile bridge on soft soil area in rupiah per square area. This research is located at Ray 2 Bridge in Barito Kuala District. In this research, bridge classifies in three types: type I (4 m segmental length, 5 spans, and 20 m total span length), type II (5 m segmental length, 4 spans, and 20 m total span length), and type III (7 m segmental length, 3 spans, and 21 m total span length). According to design results in this research, construction cost of superstructure for type I, II, and III are Rp5,795,673.4, Rp5,313,707.8, and Rp4,925,033.0. construction cos differs among types because the numbers of pier head, wherein type III has smallest number of pier head

Abstract

Metode Precast dan metode Cast in Situ merupakan metode pekerjaan drainase dengan kelebihan dan kekurangan tersendiri. Pelaksanaan Metode Precast dan Cast in Situ pada pekerjaan drainase belum bisa dikatakan tepat, sehingga perlu dilakukan analisa perbandingan mengenai biaya dan waktu pekerjaan. Tujuan dari penelitian ini untuk mengetahui seberapa besar efisiennya kedua metode tersebut. Metode penelitian yang digunakan ialah dengan perbandingan hasil antara metode Precast dan metode Cast in Situ. Data yang diolah berupa data sekunder yang didapat dari kontraktor pelaksana. Untuk penyusunan penelitian ini meliputi studi pustaka atau literatur, pengumpulan data, perhitungan volume, metode pelaksanaan dan analisa harga satuan dan biaya. Lokasi studi berada di PLTU Suralaya Banten. Berdasarkan perhitungan volume, analisa harga satuan pekerjaan, rencana anggaran biaya, analisa produktifitas pekerjaan diperoleh hasil untuk biaya metode Cast in Situ sebesar Rp 5.543.804.100,00 dan biaya metode Precast sebesar Rp 3.994.718.900,00. Waktu pekerjaan menggunakan metode Cast in Situ memerlukan waktu 116 hari sedangkan untuk waktu pekerjaan metode Precast selama 29 hari. Jumlah pekerja metode Cast in Situ sebanyak 64 pekerja dan metode Precast sebanyak 17 orang. Berdasarkan hasil analisa dapat disimpulkan metode Precast ialah metode yang paling efisien digunakan.

Abstract

Mortar is a mixture of binder and sand in a certain ratio, the binder is cement and lime. This test aims to determine the results of the compressive strength of mortar aged 3,7,14, and 28 days on variations of cement and lime mixture. The fine aggregate used in this test is Barito Sand which is included in zone 2. With the composition of the mixture used is 1 pc : 5 ps for cement and sand, the mixture used for cement, lime and sand is 1 pc : 1_4^1kp : 5 ps. From the results of this study with the same mixture proportions, the compressive strength for the variation of cement conch (PCC) = 7.40 MPa, the variation of cement gresik (PPC) = 10.41 MPa, the variation of cement conch with a mixture of lime = 4.54 MPa and strong Press the mortar for the variation of Gresik cement with a mixture of lime = 7.90 MPa. It can be concluded that the compressive strength of mortar for cement conch with a mixture of lime is higher than the variation of cement conch, gresik and conch with a mixture of lime

Abstract

The progress of building construction that is developing in our country affects the number of diverse building functions resulting in the quantity of buildings, the acceleration of the desired building and the demand for higher quality construction. Mortar is a mixture consisting of Cement, Fine Aggregate and Water. The adhesive in the mortar can be in the form of clay, lime, or cement. Fine Aggregate (Sand) in the mortar mix serves as a filler (glued material) either in a hardened or unhardened state. This final project research was conducted at the Structure and Materials Laboratory of the Banjarmasin State Polytechnic. Data collection was carried out by the method used to collect, study and collect data or sources related to the topic raised in a study. Studies can be obtained from various sources, such as journals, papers, reports, documentation books, internet (browsing) and libraries. The results of the compressive strength on the age of mortar At the age of 3 days Semen Gresik Pasir Barito is 6.05 Mpa, At the age of 7 days Semen Gresik Pasir Barito is 6.05 Mpa, At the age of 14 days Semen Gresik Pasir Awang Bangkal is 8.66 Mpa, At the age of 28 days Semen Gresik sand Awang Bangkal 10.68 MPa. It can be concluded that Pasir Barito is included in zone IV and Pasir Awang Bangkal is included in zone II. Based on the results of the average compressive strength of the mortar, the results obtained were: Barito sand at the age of 3 days was 6.05 Mpa, at 7 days old was 6.05 Mpa, aged 14 days was 7.68 Mpa, and aged 28 days was 9.56 Mpa, Pasir Awang Bangkal at the age of 3 days was 4.14 Mpa, the age of 7 days was 4.75 Mpa, the age of 14 days was 8.66 Mpa, and the age of 28 days was 10.68 Mpa.
