Abstract

Reducing the cement content in concrete is the need for environmental sustainability, as cement produces a significant carbon emission. This work aims to study the effect of partial replacement of the cement utilizing fly ash at the various percentage of substitution by investigating the physical characteristic of concrete ingredients, compressive testing at various curing age, workability, and material cost reduction. Fly ash used in this research is categorized as type F, which obtained from Jepara powerplant. Along with fly ash, ordinary pozzolan cement (OPC) from Semen Gresik used as binder material. The fine and coarse aggregates quarried consecutively from Magelang Regency and Kulon Progo Regency, Indonesia. All the constitutes being observed on specific gravity, gradation test, clay lumps content, and abrasion resistance. The job mix formula developed adopting Indonesian Standard based on the physical data obtained previously, resulting in five levels of cement replacement which is 0%, 15%,20%, 25%, and 30% compared to cementitious weight. Concrete cylinder specimen having 150 mm on the diameter and length of 300 mm, tested at various age (7,14, and 28 days) to obtained compressive strength and strength development during curing age. The current works remarks that all level of replacement obtained a good agreement with targeted compressive strength (25 MPa) at the age of 14 days. However, the more fly ash supplemented in the mixture, strength development possesses a slower rate and a slight declining on workability. Eventhough the slump value still comply with the requirement given by the Indonesian Standard.

Abstract

Introducing alternatives material on cement-based material manufacturing is the need for environmental sustainability due to the excessive mining of sand from quarry and river bed. At the same time, industrialization headed to an uncontrollable growth of waste. This fact encourages the researcher to enhance the utilization of recycled waste in construction practice. On one side, it affords a solution for waste management, and on the other hand, it contributes to an eco-friendly construction material that minimizes the environmental impact. This paper aims to investigate the usability of the iron waste obtained from the wrought iron industry, as natural fine aggregates replacement. In particular, it focused on studying the physical characteristic of waste aggregates and the effect of partial replacement of natural sand on mortar strength. Mortar cube specimen made with various levels of replacement (0%, 10%, 20% and 30 %) and also various cement-aggregates volumetric proportion, which are 1:3, 1:4, 1:5, 1:6, and 1:7. All of the measurement parameters are taken consecutively based on ASTM norms. The current work remarks that both waste aggregates and natural aggregates reveal complete fulfillment in the aggregate requirement of ASTM standard. Furthermore, the mortar cube test confirmed that the mortar passes the strength grade for N class and O class, which suitable for the above-grade and non-load bearing application.

Abstract

Kayu Jati (Tectonagrandis) merupakan kayu yang banyak tumbuh di pulau Jawa dan digunakan sebagai material konstruksi bangunan tradisional Joglo. Hingga saat ini tercatat banyak bangunan Joglo dengan kategori bangunan cagar budaya. Seiring bertambahnya usia bangunan Joglo, maka akan semakin rentan terhadap pelapukan yang berakibat menimbulkan pengurangan luas penampang sehingga kapasitas elemen strukturnya akan menurun. Dengan demikian perlu dilakukan usaha untuk memperkirakan penurunan kapasitas dari pelapukan pada elemen struktur. Penelitian ini akan mengamati secara numerik mengenai perilaku lentur dari elemen balok Kayu Jati yang mengalami pelapukan yang disimulasikan dengan takikan pada tengah bentang.Algoritma MATLAB digunakan dalam penelitian ini untuk memodelkan balok Kayu Jati sebagai material non-linier dan orthotropik. Pelapukan kayu disimulasikan dengan membuat takikan berukuran 40x60x100 mm di tengah bentang. Data mekanik material diperoleh dari studi terdahulu dan eksperimenberdasarkan ASTM D143-94(2000). Model balok Kayu Jati memiliki panjang bentang 990 mm dan dimensi penampang 60 x 80 mm. Balok Kayu Jati dimodelkan dengan elemen quadrilateral dalam asumsi planestress. Sifat non-linier material mengikuti Hill’s yield function dengan associated flow rule. Selanjutnya, hasil analisis elemen hingga divalidasi menggunakan data pengujian eksperimental pada studi terdahulu.Hasil analisis numerik memperlihatkan bahwa kurva beban-perpindahan ketiga jenis model balok Kayu Jati memiliki kesesuaian dengan hasil eksperimen uji lentur. Pola kegagalan dari semua jenis balok Kayu Jati menunjukkan bahwa kegagalan terjadi pada fase plastis (fase non-linier).

Abstract

Penggunaan beton sebagai salah satu pilihan konstruksi bangunan sipil lebih dikenal luas dibandingkan dengan bahan konstruksi lain seperti kayu dan baja. Beberapa alasan mengapa digunakan beton, karena beton memiliki kekuatan yang tinggi, proses produksi yang relatif mudah, harga relatif terjangkau, serta ketahanan terhadap cuaca yang sangat baik. Namun demikian, disamping keunggulan beton,  beton memiliki beberapa kelemahan diantaranya emisi karbon yang cukup tinggi, berat satuan yang  besar (2400 kg/m3) dan sifatnya yang kedap air. Sifat yang kedap air tersebut, apabila dilihat dari perpektif lingkungan pada konteks perkerasan jalan merupakan sebuah masalah.  Permukaan yang kedap membatasi air hujan untuk bisa meresap ke tanah, sehingga air menjadi limpasan yang kemudian terbuang ke saluran drainase. Hal ini merupakan hal yang kurang ramah lingkungan, sehingga perlu dicari upaya agar beton menjadi lebih porous sehingga mampu menjadi solusi perkerasan yang ramah lingkungan. Dengan demikian, diperlukan inovasi dalam hal produksi beton yang mampu meloloskan air / porous sebagai aplikasi dalam perkerasan yang ramah lingkungan. Pembuatan beton yang lolos air / porous (pervious concrete) secara teori akan sangat tergantung pada pembentukan rongga udara dalam beton dengan faktor penting gradasi agregat dan faktor air semen yang digunakan. Untuk menjawab kesulitan tersebut, penelitian ini akan mencoba mengaplikasikan material limbah genteng dalam menciptakan beton dengan rongga udara yang cukup untuk meloloskan air / porous. Penggunaan limbah genteng berkorelasi positif dengan nilai porositas beton. Nilai otimum antara kuat tekan dan porositas diperoleh dari penggunaan limbah genteng sebesar 15%

Abstract

Along with the development of technology and various technological advancements in the construction sector, the use of Building Information Modeling (BIM) technology has increased, as some budget planning methods still use conventional/analytical methods. This study was conducted to determine the accuracy of the BIM and analytical methods in preparing the Cost Budget Plan (RAB) by comparing the RABs of both methods. The results obtained from the comparison of concrete and reinforcement volume requirements using the analytical method were higher than those using the BIM (Building Information Modeling) method, with differences of 6,430 m3 (1.16%) and 2,293.102 kg (2.63%), respectively. The difference in concrete and reinforcement costs between the BIM (Building Information Modeling) method and the analytical method was higher, at Rp 8,065,990.45 and Rp 114,601,701.09, respectively, with a concrete cost ratio of 1.11% and reinforcement cost of 1.94%. The total Cost Budget Plan (RAB) using the analytical method was 0.71% higher by Rp 56,846,733.08 than the Building Information Modeling (BIM) method, with a total Cost Budget Plan (RAB) of only Rp 7,925,716,320.58 and a total Cost Budget Plan (RAB) using the analytical method of Rp 7,982,563,053.
