Abstract

Rainwater immersion can affect the performance of the pavement layer (laston). Falling and stagnant rainwater can cause changes in the physical and mechanical properties of laston materials, such as decreased stability, strength, and resistance to deformation. This affects the long-term performance of the pavement layer. The purpose of the study was to analyze the ability of asphalt concrete to withstand the influence of rainwater bathing. By knowing this, it can estimate the ability of asphalt concrete to withstand loads and pressures, as well as resistance to environmental influences, including rainwater, and analyze the difference in laston performance when soaked in rainwater for 24 hours and 48 hours. A trial and error method that involves experimenting with multiple samples to collect data is used. From the results of research that rainwater immersion can cause a decrease in the strength and stiffness of the asphalt mixture and the potential for cracking due to volume changes due to water absorption. The performance of laston soaked in rainwater for 24 hours and 48 hours, resulting in a decrease in stability, which was obtained 98.13% in 24 hours and 49.40% in 48 hours. The length of soaking time will affect the stability value or strength value. Keywords — Rainwater bath, Laston, Marshall characteristics, residual stability.

Abstract

Bridge construction involves uncertain risks, therefore it is necessary to carry out an analysis of all the risks that will occur, how big their impact will be (intensity), and the possibility of these risk events occurring. The method used is the Failure Mode and Effect Analysis (FMEA) method by determining severity, occurrence, detection where the results become RPN values and are determined by looking at the risk matrix table. From the risk matrix table above, conclusions can be drawn for high risk, namely the condition of the road to the project is steep, the project environment is less clean, the groundwater level is higher than the river, heavy equipment accidents, workers not wearing PPE, worker negligence and human resources not concentrating. For low risks, namely heavy equipment accidents, workers not wearing PPE and soft ground conditions. The results of the analysis using the FMEA method produced an RPN value of 64.00, it was found that 3 risk lists were included in the serious risk category and the highest risk value (NR) was 16, which was included in the high risk rating and required action to be taken.

Abstract

Abstrack – The heavy rain that occurred in Bobojong Village caused the Citanduy tributary irrigation canal to overflow by around 10-50 cm around the canal, as a result dozens of houses and roads were submerged. Other factors such as the loss of water catchment areas caused by changes in land use that affect runoff water. From the problems above, the purpose of this study is to determine the flood discharge at the 20-year return period and the water level that occurs in the irrigation canals in the Bobojong area. The method used in this study uses the Nakayasu HSS method. Based on the results of analysis on the Cimulu Building Irrigation Channel (BCMU) 39 using the Nakayasu HSS method, the 20 year return period is 34.3 m3/s. The result of the flood water level for the 20 year return period is 3042.905 m. If you look at the results, it shows that the water level is unrealistic compared to the water level in the field, where the results of field interviews show that the water level reaches 1.9 m from the bottom of the canal. so that it can be concluded that there are several possibilities that occur there, namely: The area of ​​the catchment area does not match the reality in the field or the research catchment area is larger than the actual catchment area, for the Nakayasu HSS method it is more widely used for large size watersheds and is more appropriate for flood discharge analysis return period design or return period ≥ 100 years (Eka et all., 2020)   Keywords — Synthetic Unit Hydrograph Nakayasu, Discharge, Water Level   Abstrak – Hujan deras yang terjadi di Kampung Bobojong mengakibatkan saluran irigasi anak sungai Citanduy meluap kira-kira 10-50 cm di sekitar saluran, akibatnya puluhan rumah maupun jalan terendam. Faktor lain seperti hilangnya daerah resapan air yang diakibatkan oleh perubahan tataguna lahan sehingga mempengaruhi pada air limpasan. Dari permasalahan diatas dimana tujuan dari penelitian ini adalah untuk mengetahui debit banjir pada kala ulang 20 tahun serta tinggi muka air yang terjadi di saluran irigasi wilayah Bobojong. Metode yang digunakan dalam penelitian ini menggunakan metode HSS Nakayasu Berdasarkan hasil analisis pada Saluran Irigasi Bangunan Cimulu (BCMU) 39 dengan menggunakana metode HSS Nakayasu pada kala ulang 20 tahun adalah 34.3 m3/s. Hasil dari tinggi muka air banjir kala ulang 20 tahun adalah 3042.905 m. Bila dilihat hasil menunjukan bahwa tinggi muka air tidak realistis dari tinggi muka air di lapangan, dimana hasil wawancara di lapang tinggi muka air mencapai 1.9 m dari dasar saluran. sehingga dapat disimpulkan ada beberapa kemungkinan yang terjadi dianatanya yaitu : Luas Daerah Tangkapan Air tidak sesuai dengan realitas di lapangan atau DTA penelitian lebih besar dari DTA sesungguhnya, untuk metode HSS Nakayasu lebih banyak digunakan untuk DAS dengan ukuran besar dan lebih tepat digunakan untuk analisis debit banjir rancangan kala ulang atau periode ulang ≥ 100 tahun (Eka et all., 2020)    Kata Kunci — Hidrograf Satuan Sintetik Nakayasu, Debit, Tinggi Muka Air.

Abstract

Abstract— Concrete is widely used for the construction of buildings, roads, bridges and others. The large number of concrete uses in the construction results in an increase in the need for concrete material, one of which is coarse aggregate, thus triggering the mining of stone as one of the materials for forming concrete on a large scale which causes a decrease in the amount of natural resources available for concrete purposes. Tiles made of clay are generally easier to obtain than other raw materials, apart from that in our area the remains of broken tiles or what are often called tile waste fragments are simply thrown away by the owner or sometimes only used for a mixture of landfills for local residents. The purpose of this research is to analyze the design mix design concrete mix quality fc’ 18,68 MPa with a normal concrete mix and with the addition of a mixture of coarse aggregate tile waste fragments, as well as to analyze the effect of tile waste fraction as a substitute for coarse aggregate with certain variables on the compressive strength of concrete. The method used in this study is the experimental method in the laboratory. The results of testing the compressive strength of concrete for each mixture aged 28 days resulted in concrete compressive strength values of 19,35 MPa, 17,13 MPa, 14,63 MPa and 13,76 MPa. So the results of adding tile waste fragments are not suitable for use in the quality of structural concrete. Keywords — coarse aggregate, clay tile waste, concrete compressive strength Abstrak— Beton banyak digunakan untuk konstruksi bangunan gedung, jalan, jembatan dan lainnya. Banyaknya jumlah penggunaan beton dalam konstruksi tersebut mengakibatkan peningkatan kebutuhan material beton salah satunya yaitu agregat kasar, sehingga memicu penambangan batu sebagai salah satu bahan pembentuk beton secara besar-besaran yang menyebabkan turunnya jumlah sumber alam yang tersedia untuk keperluan pembetonan. Genteng yang terbuat dari tanah liat umumnya lebih mudah didapatkan dari pada bahan baku lainnya, selain itu di daerah kita sisa genteng yang pecah atau yang sering disebut pecahan limbah genteng hanya dibuang begitu saja oleh pemiliknya atau kadang hanya dimanfaatkan untuk campuran tanah urugan warga sekitar. Tujuan dari penelitian ini yaitu untuk menganalisis perencanaan mix desain campuran beton mutu fc’ 18,68 MPa dengan campuran beton normal dan dengan penambahan campuran agregat kasar pecahan limbah genteng, serta untuk menganalis pengaruh pecahan limbah genteng sebagai pengganti agregat kasar dengan variabel tertentu terhadap kuat tekan beton. Metode yang digunakan pada penelitian ini yaitu metode eksperimen di Laboratorium. Hasil pengujian nilai kuat tekan beton pada setiap campuran umur 28 hari dihasilkan nilai kuat tekan beton masing-masing sebesar 19,35 MPa, 17,13 MPa, 14,63 MPa dan 13,76 MPa. Jadi hasil penambahan pecahan limbah genteng tidak layak digunakan pada mutu beton structural. Kata kunci — agregat kasar, pecahan limbah genteng tanah liat, kuat tekan beton
