Abstract

The city of Medan has experienced very rapid development from year to year, this has resulted in the increasingly dense traffic flow in the city. And one of the roads that experience congestion due to parking on the road body and affect the performance of road sections and is also the location of research, namely on Jalan Sutomo. Data collection techniques include survey data of traffic volume, parking volume, road section capacity and V/C ratio value. The data obtained were analyzed using the 1997 Indonesian Road Capacity Manual regulations. The traffic volume with side obstacles (H) was 504 events / hour, the road capacity before there was on street parking 6665.5 smp/hour and the road capacity after there was on street parking 4795.1 smp/hour. There is a fairly high increase due to vehicle parking activities on the road body in a very. The highest traffic density on Fridays occurs in the time interval 12.00 - 13.00. The level of road service before there is on street parking is up to level C, where the value of the V/C Ratio reaches 0.60. As for the level of road servants after on-street parking is up to level D, where the V/C Ratio value reaches 0.84, with an average speed of 44.1 km/h. With these conditions, if not handled immediately, it will affect traffic performance.

Abstract

Kecelakaan lalu lintas menurut UU Nomor 22 tahun 2009 adalah suatu peristiwa di jalan raya tidak terduga dan tidak disengaja melibatkan kendaraan dengan atau tanpa pengguna jalan lain yang mengakibatkan kerugian baik secara materi maupun penderitaan bagi yang mengalaminya. Kecelakaan disebabkan oleh kelalaian pengguna jalan, ketidaklayakan kendaraan serta ketidaklayakaan jalan atau lingkungan. Jalan Brigjend Katamso termasuk daerah rawan kecelakaan karena pada ruas jalan ini terdapat banyak kegiatan masyarakat, pertokoan, kios-kios, pedagang kaki lima (PKL), dan pemukiman penduduk. Selain itu, pada ruas jalan ini masih terdapat fasilitas keselamatan jalan yang tidak memenuhi persyaratan bangunan pelengkap jalan. Dari perhitungan nilai EAN terdapat satu segmen yang termasuk kategori blackspot yaitu pada segmen 7 dengan nilai EAN tertinggi sebesar 87 melewati batas nilai UCL sebesar 32,05894. Terdapat beberapa fasilitas keselamatan jalan yang sudah tidak layak seperti kondisi marka jalan yang telah pudar, rambu petunjuk jalan yang tertutup oleh pohon yang rimbun, tidak adanya rambu batas kecepatan, dan lampu penerangan jalan yang juga pencahayaannya tertutup oleh pohon yang rimbun. Kecelakaan yang terjadi disebabkan oleh faktor manusia sebesar 75%, kendaraan 17%, jalan dan lingkungan sebesar 8%. Berdasarkan data laka dari Satlantas Polrestabes Medan dan hasil kusioner didapat bahwasanya faktor fasilitas keselamatan jalan tidak berpengaruh terhadap kecelakan yang terjadi.

Abstract

Pembangunan di bidang konstruksi mengharuskan perencanaan yang kuat dan ekonomis. Beton merupakan campuran antara semen portland dengan agregat kasar,agregat halus,air dan menggunakan bahan tambah ADDITON H.E yang akan membentuk masa padat. Pengerasan ini terjadi karena peristiwa kimia antara semen, air dan bahan tambah. Dalam pembuatan benda uji metode yang di gunakan yaitu metode SNI,dengan kuat tekan rencana 24,4 mpa. Semen yang di gunakan adalah semen tonasa. Benda uji yang berbentuk silinder dengan φ 15 cm dan tinggi 30 cm. Pengambilan sampel material agregat halus di kali air besar (Passo), kemudian untuk pengambilan material agregat kasar yaitu pada Quary (Laha). Beton mutu K-300 yang dipakai merupakan beton mutu sedang. Mutu beton sangat tergantung dari proses produksi dan perawatannya. Pengujian Laboratorium meliputi pemeriksaan gradasi,berat jenis, penyerapan kadar lumpur,kadar air dan bobot isi. Hasil kuat tekan beton rata – rata pada hari ke 28 yaitu 38,88 N/mm². beton yang mengalami pengurangan fas 2% dengan penambahan bahan tambah 15 ml, pada umur 28 hari kuat tekan beton rata – rata 27, 63 N/mm2, untuk pengurangan fas 5% dengan penambahan bahan tambah 17 ml, pada umur 28 hari kuat tekan beton rata – rata 32,16 N/mm2, dan pengurangan fas 10% dengan penambahan bahan tambah 19 ml, pada umur 28 hari kuat tekan beton 38,00 N/mm2.

Abstract

The toll road of Padang - Sicincin uses earth embankments in the construction process. In earth filling work, there is a target that must be met, namely that it must be able to spread and compact the soil by 1,474,809 m3/day, where this volume is the plan to meet the target that has been set. The problem that is currently occurring is that the land for the toll road entrance at STA 13+300 – 13+900 on Jalan Nagari Lubuk Alung has just been acquired in 2022. From the results of a field inspection that took approximately a week, there was a delay in terms of landfill work. in the field. Therefore, it is necessary to research to find out the causes of delays. The focus of this research is to determine the productivity of heavy equipment to determine solutions to catch up with work delays that are occurring. After conducting a review in the field, the results obtained from each heavy equipment were 1,471,150 m3/day (excavator), 1,464,610 m3/day (dump truck), 3,086,070 (bulldozer), and 4,150,272 m3/day. (vibro roller). From the results obtained, the excavators and dump trucks in the field were unable to meet the planned targets. Therefore, the handling efforts carried out are by increasing the number of excavators and dump trucks working in the field. Based on the results of calculations and analysis, to complete the embankment work on time, increase the number of tools by two units for excavators and three units for dump trucks. With this additional simulation, the time required to complete work in the field is 13 days faster than the planned time that had been made.

Abstract

Seepage is an inevitable occurrence in embankment dams, but under certain conditions, it can lead to piping. Piping is the formation of cavities in the soil due to the transport of fine soil particles by seepage forces. This phenomenon is one of the serious issues that can affect the stability of the dam. This study aims to analyze the potential for piping in one of the dams located in West Java using finite element and empirical equation methods. The finite element method analysis was conducted to obtain the exit hydraulic gradient values in the dam to calculate the safety factor against piping hazards. Meanwhile, the empirical equation used the weight creep ratio (WCR) to assess the potential for piping. The potential for piping analysis was conducted under minimum, normal, and flood water level conditions. The results of the finite element analysis showed that the hydraulic gradient exit values ranged from 0.20 to 0.33, resulting in safety factors ranging from 4.58 to 8.25. The obtained safety factors still meet the minimum safety factor criteria required by SNI 8065:2016, which is 4. The potential for piping analysis using the empirical approach yielded WCR values under the minimum, normal, and flood water level conditions, which were 4.71, 3.36, and 3.30, respectively. The calculated WCR values are higher than the typical value for WCR in hard rock, which is 1.6. Based on these two analyses, it can be concluded that the dam is safe against piping hazards.
