Abstract

One of the areas in Kerinci Regency that is often hit by floods is Lubuk Suli Village.  Flooding was caused by overflowing water from the Batang Marao river. The main objective of this research is to provide information to the relevant government about good drainage for the Lubuk Suli Village Area using existing data and planning data by simulating the capability of the Drainage Network for the Lubuk Suli Village Area using the EPA SWMM 5.1 program. The data used in this research are land use maps to determine the percentage of impervious area, rainfall data and drainage channel dimension data in the area. The rain data series used is hourly rain data. Due to the absence of hourly rainfall data at the rain station at the research location, hourly rainfall distribution was determined by changing the Intensity-Duration-Frequency (IDF) curve for a 5 year return period into a planned rainfall hyetograph using the Alternating Block Method (ABM). After all parameters have been input into EPA SWMM 5.1. Simulation can be done. The simulation quality is quite good if the continuity error for surface runoff and flow tracing is > 10%. The simulation carried out in this research is divided into 2 scenarios, namely with existing data and additional storage. From the simulation results, it was found that in the 2 scenarios, the number of flood points in the simulation for scenario 1 was 6 points and in scenario 2 there were 5 points. This shows that the drainage planning design for the Lubuk Suli Village area has not been able to overcome the existing drainage load in the area.

Abstract

Beton serat adalah Beton yang dalam proses pengadukannya ditambah dengan potongan serat, baik itu serat yang berasal dari alam atau buatan. Penggunaan serat untuk mencegah terjadinya retak–retak sehingga beton menjadi lebih daktail. Selain itu, cara pencampuran maupun pengerjaannya juga mempengaruhi kekuatannya, keawetan serta sifat beton tersebut. Pemakaian beton semakin besar penggunaannya, namun bahan penyusun yang digunakan semakin mahal dan terbatas. Pada penelitian ini bertujuan untuk melakukan uji pada limbah baja ringan dengan persentase 6%, 8%, 10% dan 12% terhadap berat semen sebagai uji campuran beton yang telah ditentukan sebagai penelitian baru apakah dengan penelitian ini terdapat perbedaan hasil akhir dari campuran tersebut. Pengujian dengan cara destruktif digunakan untuk mengetahui kuat tekan pada beton yang dicampur dengan bahan tambah limbah baja ringan. Adapun hasil yang diperoleh dari penelitian ini adalah kuat tekan beton normal yang di capai pada umur 28 hari mencapai 26,81 Mpa. Hasil pengujian kuat tekan beton rata–rata dengan persentase 6% (Scrap) sebesar 20,76 MPa, dengan persentase 8% (Scrap) sebesar 21,14 MPa, dengan persentase 10% (Scrap) sebesar 16,99 MPa dan persentase 12% (Scrap) sebesar 17,17 Mpa. Nilai kuat tekan beton tertinggi yaitu pada penambahan baja ringan dengan presentase 8% kemudian mengalami penurunan pada persentase 10% dan 12%. Bahwa pada penelitian ini penambahan limbah baja ringan (Scrap) pada beton dapat menyebabkan penurunan nilai kuat tekan beton.

Abstract

This study investigates using Palm Oil Fuel Ash (POFA) as a partial substitute for some of fine aggregate (sand) in concrete mixtures. The goal is to determine the optimal percentage of POFA by testing several variations of its use as a substitute for fine aggregate. The study employed an experimental methodology involving the preparation of 15 cm x 15 cm x 15 cm cubic test specimens in accordance with SNI 03-2834-2000 (Procedures for Preparing Normal Concrete Mix Designs). The POFA percentages were 0% (control specimen), 5%, 6%, 7%, 8%, 9%, 10%, and 20%.  Test results showed that the compressive strength of concrete produced using 0% POFA (normal concrete) was 228.6 kg/cm². The compressive strengths of concrete produced using 5%, 6%, 7%, 8%, 9%, and 10% POFA were 134.9, 156.9, 159.7, 198.3, 198.3, and 151.5, 159,7 kg/cm², respectively. The test results indicate that adding POFA to the concrete decreased its compressive strength relative to control specimen. However, substituting fine aggregate with POFA at 8% and 9% resulted in higher compressive strength than the other variations. The results also indicated the potential for an increase in concrete compressive strength between 10% and 20%.
