<![CDATA[LRT Jabodebek as the first LRT infrastructure project in Indonesia has provided lessons on the implementation of dynamic capabilities on manufacturing aspects for the construction industry. In order to meet the requirements 2900 units of U-Shape Girder, production under normal conditions is expected to be completed by 2020. The acceleration of completion led to a significant increase in project requirements, accelerated completion of construction led to production shortages. Meeting the need for acceleration requires factories to be able to increase their production capacity by using steam curing methods. This case study uses a qualitative approach and focuses on dynamic capabilities in the production process. As a role model of application of manufacturing dynamic capability, the project has demonstrated the role of technology in increasing productivity. The integration of methods, asset positioning, and management processes are the most dominant productivity factors in accelerating the production of U-Shape precast girder. Optimum production performance can be achieved by integrating factory roles, project sites and management supported by adequate resources and staff experience]]>

<![CDATA[Airport pavement is designed following the US Corporation of Engineers method or better known as the California Bearing Ratio (CBR) method and the FAA (Federal Aviation Administration) method which issues regulations for calculating airport pavement structures, namely AC (Advisory Circular) 150_5320_6D which same as the method CBR. In 2021, the FAA issued a standard for calculating airport pavement structures, namely AC (Advisory Circular) 150_5320_6G which uses the FAARFIELD assistance program. The difference in pavement thickness is at most 7.6 cm, on the flexible pavement type base course. In the FAARFIELD Auxiliary Program, all aircraft loads are taken into account as a contributor to pavement damage indicated by the CDF value that can accommodate aircraft loads, in contrast to the graphical method where aircraft are converted to design aircraft. The thickness of the base course using the graphical method is greater than that of the FAARFIELD Assistance Program, this is because when performing calculations, the initial base course value is the minimum value based on the minimum base course table for the use of top foundation layer material (AC No.150_5320_6G). The thickness of the surface course pavement is the same according to FAA provisions for the critical thickness of the surface course which is 4 in or 102 mm.]]>

<![CDATA[Metode Hidrograf Satuan Sintetis (HSS) adalah metode yang sangat penting dalam perencanaan sumber daya air dan analisis debit banjir di daerah aliran sungai (DAS). Metoda ini sangat berguna, terutama untuk simulasi banjir di DAS yang mengalami perubahan penggunaan lahan. Metode HSS umumnya memiliki kekurangan, antara lain kesulitan dalam menjelaskan asal usul formula debit puncak dan ketidakakuratan dalam membandingkan volume hidrograf dengan curah hujan efektif. Selain itu, ada tantangan dalam menyesuaikan metode ini untuk durasi hujan yang berbeda-beda, dan hanya beberapa metode yang dapat dikalibrasi. Untuk mengatasi tantangan-tantangan ini, metode SUH ITB telah dikembangkan dengan beberapa fitur inovatif. Metode ini mengikuti prinsip konservasi massa dan menyederhanakan proses penurunan rumus debit puncak, sehingga menjadi alat pendidikan yang efektif. Metode ITB menggabungkan pendekatan eksak dan numerik dalam menghitung Faktor Debit Puncak (Kp), meningkatkan akurasi estimasi debit puncak yang sangat penting dalam manajemen banjir. Metode ini juga memperkenalkan Durasi Hujan Satuan Ternormalisasi (Tn), sebuah faktor tanpa dimensi yang memberikan fleksibilitas dalam menyesuaikan durasi hidrograf, memudahkan konversi ke durasi yang lebih pendek. Selain itu, metode ITB termasuk mekanisme kalibrasi yang memungkinkan pengguna menyesuaikan hidrograf dengan nilai pengukuran. Fitur-fitur inovatif dari metode HSS ITB telah berhasil ditampilkan melalui berbagai kasus dengan hasil yang sangat memuaskan.]]>

<![CDATA[Penggunaan material baja dalam konstruksi bangunan menjadikan peluang baru menuju pembangunan berkelanjutan, karena material baja memiliki sifat tahan lama dan handal dalam kekuatan dan daktilitas. Digital Image Correlation (DIC) merupakan teknik non-kontak dimana gambar digital permukaan benda uji ditangkap menggunakan kamera resolusi tinggi. Dalam penelitian, dilakukan pengukuran distribusi regangan di permukaan spesimen dengan menggunakan metode-DIC selama seluruh proses pengujian tarik material dan terutama meneliti perubahan distribusi regangan selama fase meleleh serta tahap deformasi lokal hingga gagal. Kemudian, dilakukan perbandingan kurva load-displacement hasil pengujian eksperimental laboratorium dengan hasil analisis menggunakan metode metode-DIC terhadap material baja dengan mutu SS400. Berdasarkan hasil penelitian dari uji tarik dan analisis DIC yang telah dilakukan, maka diperoleh kesimpulan dalam penelitian. Hasil pengujian tarik material baja dengan mutu SS400 ketebalan 6 mm, 8 mm, 10 mm, dan 12 mm memenuhi persyaratan mutu pada standar spesifikasi yang diuji, serta hasil kurva force-displacement antara hasil pengujian eksperimental dan metode-DIC didapatkan penyimpangan minimum dengan nilai dibawah 10%, hal ini dapat disimpulkan bahwa metode-DIC memiliki tingkat keakurasian yang cukup baik, sehingga dapat digunakan untuk memvalidasi hasil pengujian eksperimental.]]>

<![CDATA[Indonesia is a country affected by the El Nino and La Nina climate anomalies. The provinces of Aceh, Central Kalimantan, and Maluku are three regions representing parts of Indonesia that have a variety of rainfall distribution and climatic conditions. This research was conducted to determine the influence of the El Nino and La Nina climate anomalies on these three regions by looking at the areas that have a dominant influence due to these climate anomalies. The research used BMKG Indonesia rainfall data with a total of 16 rainfall stations and a data range of 22 years. The methods used for modeling are the Fast Fourier Transform (FFT) and Lomb Periodogram to obtain rainfall spectrum data. Then, the amplitude value was obtained, and a comparison of the data from the two methods was carried out to determine the recurrence value and the area with the highest impact due to climate anomalies. The results of data analysis according to the FFT and Lomb Periodogram showed that the highest affected area was the eastern part of Indonesia, namely Maluku Province, with the dominant frequency according to the FFT method being 5.61 years with a PSD of 7.67 mm2 and the Lomb Periodogram 6.06 years with a PSD of 18.64 mm2. Based on the average PSD value, using both FFT and Lomb Periodograms, it also shows that the influence of El Nino and La Nina is greatest in the eastern part of Indonesia; as you move towards the west, this influence decreases. The smallest influence occurred in western Indonesia. This shows that the influence of ENSO is more dominant than the influence of IODM.]]>

<![CDATA[The Tegal Siwalan-Banyuanyar Highway in Probolinggo Regency has been damaged at several points and has not received any maintenance for the last 7 years. This has a huge impact on road users because it can interfere with driving comfort and safety, so it is necessary to analyze the road damage that has occurred, including the type of damage and an assessment of road conditions. The Bina Marga method and a light-weight deflectometer (LWD) can be used to assess road deflection in order to assess road condition. The results of this study obtained priority order values for each segment that were in the range 5-11. The greater the value of the Order of Priority obtained, the better the road condition, whereas the smaller the value of the Order of Priority obtained, the worse the road condition. It was also found that the Bina Marga method and the Light Weight Deflectometer (LWD) tool had a poor correlation, so a comparison between the two could not be made for assessing the condition of the road surface layer. ]]>

<![CDATA[A level crossing between railways and roads is one of the critical traffic elements in a road network system as it can cause significant delays and long queues, especially when the crossing is part of an urban road network. This study aims to analyze traffic performance at level crossings using a microsimulation approach with the PTV VISSIM software. The model is designed to explicitly simulate the interaction between trains and vehicles by utilizing features such as priority rules, public transport lines, and reduced speed areas, and calibrating it based on field data. This research takes a case study of the level crossing at Jalan Abdul Rahman Saleh – Nurtanio, Bandung City. Data collection was conducted through direct observation via field surveys and data from supporting literature documents. The analysis results indicate that the existing traffic performance is at a Level of Service F, with an average intersection delay exceeding 60 seconds per vehicle. Microsimulation recommends the construction of a grade-separated intersection as a solution to improve traffic performance in the future.]]>

<![CDATA[The inter-story drift occurs as the result of rotational deformation on the frame’s joint affected by ground shaking. This rotational deformation occurs as an accumulation of bending deformation in beams and columns as well as shear deformation in the panel zone. The goal of this study is to analyze how cyclic non-linear deformation occurs in beam elements and zone panels. The 8-story steel moment resisting frame built on class D soil and designed for seismic design category D were used as model. Incremental nonlinear dynamic analysis was carried out using 20 earthquake ground motions that contained with and without pulse effects. This was done so in order to identify the median value and standard of deviation of the LS, CP, and collapse boundary conditions. Nonlinear flexure and shear deformations that occur in beam element and panel zone were explored. The results obtained show that the rotational deformation of the beam due to actual flexure is greater when compared to the rotational deformation at IDRmax reaches the first time LS and CP boundary conditions. The similar trend occurs in shear deformation of the panel zone.]]>
