Abstract

Road service quality can be determined by qualitative assessment (safety and comfort). The quality of the surface layer is one of the parameters. The HRS Base hot mix asphalt surface course, for example, is often a product failure. One of the reasons is the mismatch between the design results and the production of the mixture, for example, the gradation of mixed aggregates whose composition may deviate due to weaknesses in the production process at AMP. The first variation (10% more coarse aggregate) did not meet the specifications because there were several parameters that did not meet the requirements, namely VIM, VFB, MQ, and residual marshall stability, the second and third variations (10% less coarse aggregate and 10% more fine aggregate) the parameter values of VIM, VFB, MQ and residual marshall stability did not meet the specification requirements and only the parameter values of stability and VMA met the specifications. In the fourth variation (10% less coarse aggregate and 10% more fine aggregate), some of them met the specifications but there were two marshall parameter values that did not meet the specifications, namely the MQ value and the residual marshall stability, while in the control variable all the marshall parameter values met the specification requirements

Abstract

Terdeteksinya pergeseran dinding penahan tanah pada awal tahun 2023 di salah satu lokasi tower transmisi DD6+12, dikhawatirkan akan mengganggu stabilitas tower yang dapat mengakibatkan kegagalan struktur tower. Asesmen dilakukan secara komprehensif terhadap verticality tower, pergeseran dinding penahan tanah, kondisi di bawah permukaan tanah, dan sifat-sifat tanah di sekitar area tower. Hasil asesmen menunjukkan adanya kemiringan pada tower transmisi secara linier dari bawah ke puncak, dengan defleksi di puncak ±20 cm ke arah selatan dan ±7 cm ke barat. Dengan kondisi ini rasio tegangan tehadap tegangan ijin elemen struktur ada yang mencapai 0.91. Walaupun masih dalam batas ijin, jika stabilitas tanah tidak diperbaiki, dikhwatirman tower akan mengalami kegagalan struktur. Scan GPR menunjukkan adanya perbedaan dimensi pondasi dengan as built drawing dan ditemukan adanya rongga di bawah permukaan tanah yang terisi air karena tidak terdrainasi dengan baik, dimana faktor kemanan dalam kondisi ini 1,088 sementara yang disyaratkan 1,5. Kondisi ini yang menyebabkan terjadinya pergeseran dinding penahan tanah. Rekomendasi pembuatan terowongan drainasi (drainage tunnels) di sisi hulu, soil grouting, pemasangan wheep hole pada dinding penahan tanah dan menambahkan secant pile, akan menaikkan faktor keamanan menjadi 1,988.

Abstract

Abstract This research explores the transformation of unsignalized intersections into signalized intersections as a strategy to increase efficiency and safety in traffic management. The main objective of the research is to evaluate the impact of these changes on vehicle flow, traffic density, accidents, and travel time efficiency. The research method was carried out through a combination of field observations, traffic volume data collection, statistical analysis, and simulation modeling. The results showed significant changes after the intersection transformation, with a significant increase in the average speed of traffic flow and a reduction in density during rush hours. In addition, accident analysis shows a decrease in the number of traffic incidents that occurred after the implementation of the signalized intersection system, indicating increased safety for road users. The results of this research show that the transformation of unsignalized intersections into signalized intersections has a significant positive impact in optimizing traffic performance. This research makes an important contribution to the understanding of the benefits of changes to traffic infrastructure and provides a basis for decision making in improving urban transport systems. The implications of this research can be used as a guide for policy makers in planning similar transformations in other locations to improve overall traffic system performance.

Abstract

Sustainability is usually associated with energy source, ecological, soil and environmental aspects. Periodical road and bridge preservation is required to ensure the increasing of accessibility and mobility level, to increase regional economics’ growth, to minimize unplanned or unpredicted environmental consequences and to improve institutional arrangement capability as well. Road and bridge preservation is commonly managed based on its level of damage and constrained in budgeting. Poor public policy makes it worst. Therefore, the issue of strengthening the capacity of regional road and bridge management institutions is deemed important and urgent not only to reduce roads and bridges preservation cost but also to increase regional economics’ growth. Therefore, a proper road preservation type and priority should be determined based on technical, socio-economics, environment and public policy consideration. However, annual road and bridge functional condition data collection took high cost because it has been carried out by engineering consultant. The aim of this study is resolve it by providing a public participation portion in a road and bridge data base model. They are simply asked to send a real time condition of road s or bridge nearby to the local authority. The results strongly indicate that cost saved obtained from it could be focused to road and bridge preservation cost.

Abstract

Drainase pada ruas jalan Gua Lourdes, Kelurahan Oetete, Kota Kupang sering mengalami luapan banjir pada waktu musim penghujan. Kondisi ini menyebabkan banjir pada jalan dan daerah disekitar lokasi tersebut. Evaluasi dilakukan untuk mengetahui kemampuan saluran drainase pada daerah pengamatan dalam mengalirkan debit banjir pada kala ulang yang ditinjau yaitu kala ulang 2 tahun, 5 tahun, 10 tahun, 25 tahun, 50 tahun dan 100 tahun. Panjang saluran yang ditinjau ke hulu 143 m dan ke hilir 188 m yang dibagi dalam 7 segmen. Evaluasi dilakukan dengan membandingkan debit banjir rancangan (Q) dan debit banjir pada saluran drainase eksisting (Qs). Hasil perhitungan debit banjir rancangan (Q) diperoleh dengan menjumlahkan debit banjir air hujan (Qah) dengan Metode Hidrograf Satuan Sintetik Nakayasu dan debit air kotor (Qak). Hasil yang diperoleh pada kala ulang 2, 5, 10, 25, 50 dan 100 tahun adalah 86,142 m3/det, 118,641 m3/det, 150,152 m3/det, 181,881 m3/det, 208,075 m3/det, dan 234,292 m3/det. Sedangkan hasil perhitungan untuk debit banjir saluran drainase eksisting pada tiap segmen yaitu 30,629 m3/det, 20,387 m3/det, 27,906 m3/det, 26,248 m3/det, 22,038 m3/det, 16,927 m3/det, 53,259 m3/det. Sehingga setelah dilakukan evaluasi, diperoleh kondisi dimana debit banjir rancangan lebih besar daripada debit saluran drainase eksisting (Q>Qs) untuk setiap kala ulang. Oleh karena itu, penampang saluran drainase eksisting pada lokasi yang ditinjau tidak dapat menampung debit banjir rancangan pada kala ulang 2, 5, 10, 25, 50 dan 100 tahun. Untuk itu, perlu dilakukan perencanaan ulang pada saluran tersebut dengan menggunakan ukuran penampang dimensi saluran yang paling ideal yaitu pada kala ulang 2 tahun sehingga diperoleh kondisi dimana saluran drainase dapat menampung kapasitas debit banjir rancangan.

Abstract

Transportation is the movement of people and goods from one place to another so that transportation activities generally influence the optimal movement system from one place to another. In order to travel to the place you want to go quickly and efficiently, transportation is needed to support these needs. Travelers mostly use private vehicles to travel to their destination rather than using public transportation, causing vehicle congestion on the roads. This research aims to find out what factors influence workers in choosing modes of transportation and also maximize the use of public transportation among South Tangerang workers. Data obtained from distributing questionnaires which were then processed with the help of SPSS software included Partial Correlation Tests between Variables, Simultaneous Correlation Tests between Variables, Model Fit Tests, and Binary Logistic Regression. The results of the analysis show that there are 2 variables that have a partial influence, namely Gender and Frequency of Using the Bus. So the results obtained for the male gender who always use the bus are 99.97%, and for the female gender who always use the bus it is 84.16%.

Abstract

Jalan Farmasi dan Jalan Bumi I yang terletak di Kelurahan Liliba dan Keluarahan Oesapa Selatan memiliki pemukiman yang cukup padat. Tidak tersedianya saluran drainase menyebabkan terjadinya genangan dipermukaan jalan apabila terjadi hujan dengan intensitas yang cukup tinggi. Berdasarkan hal tersebut, maka dilakukan perencanaan saluran drainase serta bangunan-bangunan pelengkap apabila diperlukan. Data hujan yang digunakan diambil dari 3 pos hujan, yaitu Pos Hujan Lasiana, Eltari dan Tarus selama 20 tahun (2002-2021). Data hujan harian dianalisa curah hujannya kemudian dilakukan uji parameter statistik dan uji kecocokan, maka metode Log Pearson Tipe III layak dipakai dalam perencanaan saluran dengan kala ulang 5 tahun serta besar curah hujan harian adalah 139,014 mm. Debit rencana diperoleh dari debit air hujan (QAH) ditambah dengan debit air kotor buangan penduduk (QAK), debit rencana setiap saluran berbeda-beda, berkisar antara 0,036 m3/dtk sampai 6,959 m3/dtk. Saluran drainase yang akan direncanakan terdapat 152 saluran dengan dimensi rata-rata, yakni (H) = 0,750 m dan (b) = 0,690 m. Sedangkan bangunan pelengkap terdiri dari Gorong-gorong, bak penampung dan inlet saluran drainase. Bangunan pelengkap juga memiliki dimensi yang bervariasi. Gorong-gorong yang direncanakan terdapat 82 bangunan dengan dimensi rata-rata, yakni (d) = 0,657 m, Bak penampung yang akan direncanakan terdapat 67 bangunan dengan dimensi rata-rata, yakni (H) = 1,192 m dan (b) = 0,570 m, dan inlet saluran drainase direncakan dengan dimensi (d) = 0,100 m dan (L) = 0,200 m.

Abstract

Transportation is an activity of moving something (goods and/or goods) from one place to another, either with or without means. In this context, ownership and use of private and public vehicles can be said to be an alternative for society in meeting movement demands, for example in carrying out daily trips or daily activities and work. However, the pandemic problem used to be one of the causes of the decline in people's daily activities, but now it has started to improve and people's activities are starting to return to normal. This research aims to determine the choice of transportation modes used by the people of Paku Jaya sub-district after the pandemic is over or the new normal and to find out the factors that influence mode users' preferences for daily travel. Data obtained from distributing questionnaires was processed with the help of SPSS software including Chi-Square Test, Cross Tab, and Regression Analysis. It is known that out of 100 respondents, 85 respondents used private vehicles and 15 respondents used public transportation. It is known that variations in gender characteristics, vehicle ownership, and driver's license ownership have significant differences in choosing a mode of transportation. And it is also known that the variables gender, vehicle ownership, and driver's license ownership have a significant influence on mode choice
