ABSTRACTPile cap is one of the many types of structures that are entirely Disturbed-region. The structure undergoes a non-linear strain because it was meeting point of the pile and column with centralized forces. In addition, geometry changes occur at the meeting between the column, pile cap, and pile, so the Bernoulli concept is no longer suitable for this condition. Pile cap testing consists of two groups of specimens and each group consists of three specimens. The first group was designed using the STM method (SNI 2847: 2013 Appendix A) and the second group was designed using conventional methods (SNI 2847: 2013 Article 15). Loading is the application of a centralized static load that is channeled through a centric column until the pile cap structure has collapsed. The results show that: (1) The flexural reinforcement which experiences the first yield condition both on the pile cap testing of the STM method and in the conventional method was the X direction flexural reinforcement (outsidest flexural reinforcement). (2) The average strain of the yield conditions and load on the pile cap STM method were 2242 με and 528.97 kN, whereas the conventional method were 2436 με and 437.03 kN. (3) Increasing the load capacity of the yield conditions (Py) of the pile cap STM method and conventional method on the plan load (Pn) were 32.2% and 9.3%.Keywords: pile cap, four piles, Strut and Tie Model (STM) ABSTRAK Pile cap merupakan salah satu dari jenis struktur yang sepenuhnya merupakan daerah terganggu (Disturbed-region). Struktur tersebut mengalami regangan non-linear karena merupakan titik pertemuan pile dan kolom dengan gaya-gaya terpusat. Selain itu, terjadi perubahan geometri pada pertemuan antara kolom, pile cap, dan pile, sehingga konsep Bernoulli tidak cocok lagi pada kondisi tersebut. Pengujian pile cap terdiri dari dua kelompok benda uji dan masing-masing kelompok terdiri dari tiga buah benda uji. Kelompok pertama dirancang menggunakan metode STM (SNI 2847:2013 Lampiran A) dan kelompok kedua dirancang menggunakan metode konvensional (SNI 2847:2013 Pasal 15). Pembebanan berupa penerapan beban statik terpusat yang disalurkan melalui kolom sentris sampai struktur pile cap mengalami keruntuhan. Hasil menunjukkan bahwa: (1) Tulangan lentur yang mengalami kondisi leleh terlebih dahulu baik pada pengujian benda uji pile cap metode STM maupun pada metode konvensional adalah tulangan lentur arah X (tulangan lentur terluar). (2) Rata-rata regangan kondisi leleh dan beban pada benda uji pile cap metode STM adalah 2242 με dan 528,97 kN, sedangkan pada metode konvensional adalah 2436 με dan 437,03 kN . (3) Peningkatan kapasitas beban kondisi leleh (Py) pada benda uji pile cap metode STM dan metode konvensional terhadap beban rencana (Pn) adalah 32,2 % dan 9,3 %.

Beton porous non pasir dengan slag baja merupakan salah satu beton yang ramah lingkungan. Beton ini dapat menjadi alternatif untuk mengatasi permasalahan kerusakan jalan akibat genangan air, terutama pada trotoar, jalan taman, atau jalan lingkungan dalam skala terbatas. Slag baja dapat menggantikan agregat kasar karena memiliki kuat tekan yang mendekati agregat batu pecah. Penelitian ini bertujuan untuk menganalisis pengaruh substitusi steel slag terhadap kuat tekan beton porous non pasir. Penelitian eksperimental ini menggunakan dua variasi faktor air-semen (w/c 0,25 dan w/c 0,3) dengan dua variasi agregat batu pecah dan steel slag dengan diameter 10 mm-20 mm. Uji tekan pada benda uji dilakukan pada umur 14 hari, 21 hari, dan 28 hari. Penelitian ini mengacu pada ACI 522R 10. Penelitian ini menunjukkan bahwa kuat tekan beton porous non pasir menggunakan steel slag sebagai agregat kasar memiliki kuat tekan yang lebih rendah dibandingkan beton tidak halus porous menggunakan batu pecah.

Abstract Nickel slag is effluent from the nickel ore waste management process which has no economic value. Based on the visual aspect, nickel slag has a physical form that resembles coarse or fine aggregate. The chemical composition of the most nickel slag is silica with a percentage of 41.47% which is expected to strengthen the hydration process and increase the compressive strength of concrete. Concrete treatment is one of the things that can affect the strength of concrete. Concrete treatment generally uses water that is free from chemical and other substances that can affect the quality of concrete. Concrete in buildings located around the sea will experience direct contact with sea water, while sea water contains elements of salt and high chemical content which can cause a decrease in the quality of concrete. This decrease in the quality of concrete will affect the mechanical properties of the concrete, especially the compressive strength of the concrete itself. Therefore, this study aims to identify the effect of using nickel slag as a substitute for coarse aggregate with seawater immersion on the compressive strength of concrete. The method in this study is using the experimental method by making 48 concrete specimens with 4 variations, namely B.BP, L.BP, B.SN, and L.SN with testing the compressive strength of concrete at the age of 7, 14, 21, and 28 days. The results of the compressive strength test at the age of 7.14, and 21 days, the highest percentage of the compressive strength of concrete was 58.25%; 50.06%; 35.93%; on the variation of B.SN to the variation of B.BP, while at the age of 28 days the variation of L.SN experienced an increase in the compressive strength of concrete by 18.54% against the variation of B.BP.
