Abstract

The Bandar-Lurus River empties into the Batang-Kurao River at an almost perpendicular confluence. As a result, when the Bandar Lurus flowed the 2021-August-18 flood-discharge, for example, the Kurao river-bank collapsed. If this is allowed to last longer, then the resident houses near the river bank could be damaged. The flow velocity is predicted using the Manning formula, and the resistance coefficients are averaged using the Einstein-Banks formula. Both formulas are then solved using the Newton-Raphson method on the MS Excel platform. The objective of this study is to slow down the Bandar downstream velocity of the as slowly as possible to minimize damage to the Kurao river-bank. The first step is to lower the longitudinal slope of the Bandar bed from 0.0012 to 0.0007. As a result, the downstream velocity is expected to slow down from 1.85 to 1.68 m/s, and the water level is also estimated to drop from 6.79 to 5.98 m. The next step is to replace the Bandar-bed material from the ground with irregular sharp-rock fragments. Consequently, the velocity is expected to slow down from 1.68 to 1.19 m/s, but the water level is estimated to rise from 5.98 to 6.94 m. This is the Bandar velocity that can be engineered considering that the channel-top elevation in the downstream is only 8.24 m including the freeboard.

Abstract

Abstract: This study summarizes the development of response spectrum analysis while introducing a Python-based programming framework for computing both elastic and inelastic response spectra. Validation is conducted using data from the 1940 El Centro earthquake, with results compared to those from a commercial application. The elastic response spectra from all methods show close agreement, whereas the inelastic responsedeveloped using a trilinear pushover curve with positive post-yield stiffness, post-ultimate strength deterioration, and a hysteretic modelcan produce higher or lower peak accelerations due to its dependence on input parameters. This open-source framework will be made available through a GitHub repository, allowing broader access for researchers and practitioners in earthquake engineering.Abstrak: Penelitian ini merangkum perkembangan analisis respons spektrum sekaligus menawarkan kerangka pemrograman berbasis Python untuk menghitung respons spektrum elastik dan inelastik.

Abstract

Bencana alam banjir dapat terjadi karena limpasan air sungai yang keluar dari alur sungai saat kapasitas sungai tidak mampu menampung aliran yang terjadi. Banjir akibat luapan air sungai juga terjadi di Daerah Aliran Sungai (DAS) Tripa, Aceh. Banjir yang terus berulang menimbulkan keresahan bagi masyarakat yang tinggal di sekitar daerah Sungai Krueng Tripa. Maka dari itu diperlukan kajian untuk melihat sebaran genangan banjir akibat dari meluapnya Sungai Krueng Tripa. Dalam menetapkan sebaran genangan banjir diperlukan analisis banjir rencana dengan metode Hidrograf Satuan Sintetis Soil Conservation Service (SCS) yang menghasilkan nilai debit banjir maksimum pada periode ulang 2, 5, 10, 25, 50, dan 100 tahun ialah sebesar 1273,35 m/dt, 2092,41 m/dt, 2670,03 m/dt, 3361,64 m/dt, 4036,57 m/dt, dan 4664,72 m/dt. Hasil perhitungan debit banjir di-input kedalam software HEC-RAS 2D dengan aliran unsteady flow dan menghasilkan luasan sebaran genangan banjir pada setiap periode ulang sebesar 41,29 km, 68,14 km, 86,66 km, 108,35 km, 128,58 km, dan 142,54 km. Pembentukan peta genangan banjir dibantu dengan software ArcGIS 10.8.2. Validasi genangan banjir hasil pemodelan HEC-RAS dengan titik sebaran banjir didapatkan persentase genangan banjir pada setiap periode ulang menggenangi 3,45%, 27,59%, 46,55%, 77,59%, 82,76%, dan 91,38% titik sebaran banjir di DAS Tripa.

Abstract

With the advancement of concrete technology, including types of cement, materials, additives, test specimen shapes, and environmental conditions, the compressive strength conversion factors of concrete differ from those in PBI 1971, which is based on OPC cement. PBI 1971 does not yet account for conversion factors for high-strength concrete and requires adjustments for PCC and PPC cement. This study focuses on determining the compressive strength conversion factors for normal-strength and high-strength concrete at the ages of 3, 7, 14, 21, and 28 days using PCC and PPC cement, while also analyzing their effects on workability, compressive strength, and the rate of strength development. The research employs normal-strength concrete (25 MPa) and high-strength concrete (42 MPa) according to SNI standards, with the addition of 10% silica fume and 0.5% superplasticizer. Compressive strength tests were conducted using cylindrical specimens. The compressive strength results were modeled into regression equations, which were then used to calculate the conversion factors by dividing the average compressive strength of concrete at a specific age by the average compressive strength at 28 days.The results indicate that for normal-strength concrete, PCC cement yields higher conversion factors than PBI 1971 at 3 and 7 days, although the differences are not significant. Meanwhile, PPC cement tends to show higher values at 3 and 7 days due to its pozzolanic content. For high-strength concrete, the conversion factors for PCC and PPC cement are relatively similar to those in PBI 1971, except at 3 days, where PPC cement yields higher values. The conversion factors derived from this study are not significantly different from PBI 1971, and their application can be considered based on construction requirements, such as using PPC, PCC, or OPC cement for high early strength. PCC cement enhances workability and the rate of strength development, while PPC cement provides higher early and final compressive strength, applicable to both normal-strength and high-strength concrete.

Abstract

East Kalimantan Province, located on Indonesias largest coal-exporting island, relies heavily on the Mahakam River as a major water transportation route. In a jetty construction project along a tributary of the Mahakam River in East Kalimantan, modifications were made to the structure from the original design, presumably contributing to the dolphin structure's displacement. Soil test data indicate predominantly clayey soil, with hard layers at approximately 20 m depth. This study aims to evaluate the structural strength of the initial design and the existing condition through manual calculations and SAP2000 analysis. Manual calculations utilize N-SPT values, while SAP2000 models soil as a spring element based on the Nakazawa Method. The study evaluates the existing dolphin structure using numerical modelling and manual calculations, showing an increase in vertical capacity from 231.17kN to 302.82 kN and a reduction in displacement from 43.3mm to 23.3mm. Despite depth modifications from the original design, the berthing dolphin structure remains structurally safe for its intended function.East Kalimantan Province, located on Indonesias largest coal-exporting island, relies heavily on the Mahakam River as a major water transportation route.

Abstract

Simpang Martoloyo has a high traffic flow because it is the meeting point of arterial roads that include residential areas, school areas, and offices, as well as business locations, namely Pasar Anyar Martoloyo. This condition resulted in congestion and long delays. This study aims to analyze the performance of signalized intersections at Simpang Martoloyo, provide recommendations, and model traffic engineering using VISSIM software. The calculation method used is Pedoman Kapasitas Jalan Indonesia (PKJI) 2023. Based on the results of the analysis of existing conditions, Simpang Martoloyo has a service level of F with an average delay of 105.96 seconds/junior high school. The improvement of the performance of Simpang Martoloyo is carried out through several traffic engineering in the form of widening the approach to the intersection, changing the cycle time, and redesigning the number of phases. The alternative handling is selected based on the most optimal improvement in intersection performance. The redesign of the cycle time to 104 seconds with a green time of 10 seconds for each phase shows the results based on PKJI calculations that this alternative can improve intersection performance by reducing the average delay to 86.07 seconds/smp, and then based on Vissim modeling, it can reduce the average delay to 41.71 seconds. The time change between the greens is considered to be able to empty the last vehicle at the point of conflict of each last phase signal.

Abstract

This study evaluates the impact of railway-induced vibrations on an equipment building near Gedebage Station, Bandung. Proximity to the railway track raised concerns about occupant comfort and structural integrity. The assessment employed microtremor analysis to determine natural frequencies of the soil (using HVSR method) and the building (using FSR method), alongside PPV analysis to measure vibration levels against regulatory standards. Results revealed that the train-induced vibration frequency (~37 Hz) did not coincide with the buildings natural frequency (~23 Hz), eliminating resonance risks. However, moderate natural resonance vulnerability was detected on the first floor in the east-west direction. While some PPV values exceeded Indonesias environmental thresholds (Kepmen LH) for minor plaster cracks (category B), all remained within DIN 4150-3 safety limits for commercial structures. In conclusion, the building faces no immediate structural threat, but train vibrations may cause minor non-structural disturbances, such as cosmetic cracks. Mitigation measures could enhance occupant comfort, though structural reinforcement appears unnecessary. The findings highlight the importance of vibration monitoring in infrastructure planning near railways.

Abstract

The implementation of green building construction in Indonesia is still limited, despite the increasing environmental damage caused by the conventional construction industry. The government has issued several regulations on green buildings and sustainable construction, but implementation is still not optimal. Furthermore, the concept of Green Jobs, as jobs that contribute to preserving or restoring environmental quality, is not yet widely recognized by construction service providers in Indonesia. In fact, a workforce with sustainable development knowledge and skills is crucial to support environmentally friendly construction practices. This study aims to evaluate the importance and application of green construction principles in the construction sector and determine priority actions. The research method used is Importance Performance Analysis (IPA), which involves administering questionnaires to construction stakeholders. This study is expected to provide a basis for formulating policies for developing Green Jobs by improving the competency of human resources for sustainable development. The results indicate a gap between high importance and low performance, with three important areas as the main priorities: mastery of green building technology, Zero Energy/Low Emission Building Systems, and Building Information Modeling (BIM) for sustainability. Proposed strategies include certified training, integrating sustainability criteria into procurement, and encouraging public-private partnerships for technology transfer. These findings provide a roadmap for all industry stakeholders to accelerate the development of a sustainable construction-skilled workforce.
