<![CDATA[Waste tires are a serious problem in many countries in the world, including Indonesia, this is because waste is a solid material that is difficult to decompose and even recycle. The utilization of waste tires in the field of civil engineering and environmental infrastructure is something that needs to be developed. Utilization of rubber powder can be used as a partial substitute for sand in concrete mixtures used in structural concrete and non-structural concrete. This research was conducted by experimental method on cylindrical specimens to test the compressive strength and concrete blocks to test the damping power of 28 days old concrete. The test parameters are the compressive strength and damping coefficient of the rubber powder mixture. The variation of thetest object used is the replacement of used tire rubber powder against sand by 0%, 5%, 10%, 15%, and 20%. The test results show that the more mixture of rubber powder in the concrete can reduce the compressive strength of the concrete and increase the damping ratio of the concrete.]]>

<![CDATA[The addition of asphalt material is expected to increase service life and minimize maintenance costs from conventional ballast structures. The purpose of this study was to determine the weight of test material + asphalt 3%, compressive strength, vertical deformation, elastic modulus, abrasion value and damage to the test specimen after loading. The method used was the compressive test method while for the test object used consists of dirty ballast, clean ballast, dirty ballast + 3% asph alt 1 layer, dirty ballast + 3% asphalt 3 layers, clean ballast + 3% asphalt 1 layer, clean ballast + 3% asphalt 3 layers. The test objects were modeled with a cube measuring 0.4 x 0.3 x 0.2 m. The test results show that the addition of asphalt can increase the deformation value and can reduce the modulus of elasticity. However the presence of asphalt as a binding material can minimize the valueof abrasion and damage to the reciprocating constituent material. ]]>

<![CDATA[Before 2020, Kentungan is the one of the densest intersections in Yogyakarta. This intersection is important due to it connected with all primary roads across level of the authority. Therefore, this intersection will be modified in the form of an unpassed intersection (underpass). The purpose of this study is to explore the model of the unconventional form of the intersection with the form of Partial Cloverleaf B2 (Parclo B2), thus that it can be optimized in traffic performance and safety. The method used in this study is the use of a software microsimulation program, PTV. Vissim 9, which models 3 scenarios, namely existing conditions, the Parclo B2 model with the default form, and the Parclo B2 model with modifications. Based on the three results of the model, the existing conditions that initially had a Level of Service (LOS) F with a delay value of 104.79 seconds can rise with LOS D with a value of 54.9 seconds. Based on the models result, Partial Cloverleaf B2 (Parclo B2) is able to reduce traffic congestion even though it still has some advantages and disadvantages.]]>

<![CDATA[Pertumbuhan dan perkembangan kota-kota besar di Indonesia tergolong cukup pesat. Khususnya kota Bandung yang merupakan pusat pariwisata di wilayah Jawa Barat. Salah satu akses menuju tempat pariwisata di Kota Bandung dan merupakan ikon Kota Bandung. Disamping itu, Jalan Ir.H Juanda memiliki permasalahan yaitu tingkat kemacetan yang tinggi dan banjir pada musim penghujan. Sepuluh tahun terakhir kawasan Jalan Ir.H. Djuanda selalu banjir jika terjadi hujan deras. Hal ini menyebabkan genangan air masuk ke ruas Jalan Ir.H Juanda yakni dari Pasar Simpang menuju Terminal Dago. Hal ini berdampak pada kerusakan jalan, drainase, dan kemacetan. Untuk mengetahui risiko terjadinya luapan saluran pada wilayah kajian sebagai akibat berbagai besaran debit banjir, dilakukan analisis metode safety factor dan first order-second moment. Hasil analisis menunjukkan terdapat 2 titik yang memiliki peluang untuk terjadinya luapan yaitu di lokasi Masjid Al-Ihsan dan Bengkel Honda. Solusi yang diberikan untuk mengatasi hal tersebut adalah melakukan normalisasi drainase dengan ukuran 1.5 m x 1.5 m dari hulu hingga hilir. Hasil menunjukkan bahwa keandalan saluran meningkat menjadi 92.96 % (Q2), 88.54 % (Q5) dan 85.81 % (Q10) untuk saluran Masjid Al-Ihsan serta 100 % (Q2), 99.98 % (Q5) dan 99.92 % (Q10) untuk saluran Bengkel Honda. Metoda pada analisis risiko di atas dapat menghubungkan probabilitas kegagalan atau pelampauan dengan harapan keberhasilan fungsi suatu struktur penampang drainase dalam menampung aliran banjir.]]>

<![CDATA[Kondisi Sumatera Selatan yang memiliki sungai musi yang panjang dan berbatasan dengan. Kepulauan Bangka Belitung membuat perjalanan lalu lintas keairan menjadi perhatian penting. Selain itu hasil sumber daya Sumatera Selatan berupa minyak, gas alam, dan batu bara dan lain-lain menjadi pusat industri yang pemasarannya melalui jalur darat dan laut. Berdasarkan hasil ekspor import pelabuhan Boom Baru merupakan akses ekspor import terbesar di Sumatera Selatan. Oleh karena hal itu kunjungan keluar masuk kapal dalam dan luar negeri harus dilakukan dengan seksama dan terekam secara baik. Back Propagation merupakan simulasi buatan yang dibuat berdasarkan system kerja jaringan syaraf tiruan. Simulasi ini meniru data input yang dimasukkan sehingga menghasilkan data output yang mendekati hasil dari data input. Simulasi ini juga memiliki kecanggihan berupa menirukan data range yang berada diantara data input. Sehingga memudahkan dalam memprediksi data yang tidak ada didalam data input. Data kunjungan kapal dalam dan luar negeri diambil dari data Badan Pusat Statistik Sumatera Selatan dari tahun 2019 sampai 2021. Hasil simulasi Back Propagation untuk data kunjungan dalam negeri yang menghasilkan eror terkecil 0,92% dengan trial epoch sebanyak 175693 dan mengalami eror data di 53%. untuk data kunjungan luar negeri yang menghasilkan eror terkeci 1,44% dengan trial epoch sebanyak 189367 dan mengalami eror data di 73%. Dapat disimpulkan bahwa simulasi Back Propagation mampu memprediksi data kunjungan kapal dalam dan luar negeri.]]>

<![CDATA[Makassar City is often experiences flood during rainy season and lack of water during dry season. Therefore, Jenelata Dam is planned to be built in South Sulawesi with a watershed area of 221.22 km2. Every dam has a dambreak potential due to many factors such as earthquakes.  Risk analysis is carried out in order to study the most effective mitigation plan on minimizing the risk index. Flood hydrograph modeling due to dambreak is done using HEC-HMS with the most extreme dambreak scenario is due to overtopping with a discharge peak of 48726.47 m3/s. The flood inundation modeling is done using HEC-RAS with the inundation area due to overtopping was 20842.48 Ha. The results of the inundation map and demographic data are then used as the basis for determining the risk index per sub-district. The mitigation plan is in the form of structural and non-structural. The structural solution was determined through testing the effectiveness of every solution on reducing the flood inundation area, where the installation of embankments with 150 cm high on the main and river branch give the best result. Implementation of the mitigation plan is based on the risk index value of the sub-district and its components. The final result is a risk index with implementation of the mitigation plan as a comparison to the risk index without the mitigation plan. The result obtained is a decrease in the risk index on several sub-districts from high to medium or medium to low. ]]>
