Porositas dapat didefinisikan sebagai ruang kosong diantara material (volume ruang kosong yang ditempati oleh fluida) terhadap volume total beton. Beton merupakan salah satu bahan yang sering digunakan dalam struktur bangunan yang mempunyai beberapa kelebihan dan mudah digunakan dan dikerjakan, mudah di bentuk sesuai kebutuhan, proses perawatan juga mudah dilakukan, ekonomis dalam pembuatannya karena menggunakan bahan–bahan lokal yang mudah diperoleh. Secara struktural beton memiliki kekuatan yang cukup besar dalam menahan gaya tekan. Beton dengan campuran serat merupakan beton yang dicampur dengan material serat serabut kelapa sawit, tetapi bisa juga diberikan tambahan berupa serat alami dan serat sintetis yang dapat digunakan untuk memperbaiki kualitas dari beton. Penambahan serat serabut kelapa sawit dalam campuran adonan beton bisa memberikan kontribusi yang positif dalam pemanfaatan limbah serabut kelapa sawit. Penelitian ini dalakukan dengan menggunakan metode eksperimen dengan membuat sampel uji beton berbentuk kubus dengan ukuran 50x50x50mm kemudian dilakukan uji porositasnya. Hasil analisis regresi terhadap nilai porositas beton setelah di tambah dengan serabut kelapa sawit diperoleh (P) sebesar 21,02761%.

Cement as a building material for concrete produces CO 2 which can damage the earth's atmosphere. Therefore, environmentally friendly geopolymer concrete is the choice. The main ingredients for making this concrete are pozzolanic materials which are rich in Silica (SiO 3 ) and Alumina (Al 2 O 3 ) as a substitute for cement and alkali activator in the form of Sodium Hydroxide (NaOH) and (Na 2 SiO 3 ) as binders. This study aims to determine the variation of the mixture for the highest compressive strength. The ratio of fly ash type F and alkali activator is 74%:26%. The molarity of NaOH used was 10M, 12M, 14M, the ratio of Na 2 SiO 3 and NaOH was 2.5:1; 3.0:1; 3.5:1. The test object is cylindrical size 15cm x 30cm and the compressive strength test is 28 days old. The test results with the ratio of NaOH and Na 2 SiO 3 2.5:1 at 10M, 12M, 14M NaOH are 25.81 Mpa, 27.00 MPa, 28.98 MPa. While the compressive characteristics are 24.32 Mpa, 24.67 Mpa, 26.58 Mpa. The test results show that the ratio of molarity and alkali activator greatly affects the compressive strength and workability of geopolymer concrete. High molarity will produce high compressive strength. Meanwhile, the higher the alkali activator ratio, the lower the compressive strength produced.

Knowledge and analysis about flood discharge in Selabung watershed is used as spillway planning. Selabung watershed with Selabung River as the main river and 71.29 km long. Flood’s controlling in spillway is needed especially when water level almost reachers the maximum discharge. The purpose of this study was to determine the design flood discharge in Selabung watershed for the 100 year return period. The primary data in this study is morphological observation data and the secondary datas are rainfall data from 2001 to 2014, topographic data, land use, and river cross-section data. The calculation of rainfall average for three rain stations used Poligon Thiessen method. From the calculation of design flood discharge for 100-year return period using The Nakayasu Synthetic Unit Hydrograph, the discharge is 36.89 / s.
