Abstract

Muara Gembong Sub-district, Bekasi Regency, West Java Province, has many damaged and bumpy roads. This area is coastal and some parts of the area are swampy soils that have low bearing strength, not meeting the required bearing strength (CBR) of at least 6%. This research aims to analyze the effect of the addition of sawdust ash and clam shell powder as soil stabilization material on bearing strength, in this case the California Bearing Ratio value. The method used in this research is a laboratory experiment of soft soil stabilization mixed with additive materials in the form of sawdust ash and clam shell powder at a proportion of 2% and 4% to the dry weight of the soil. Tests carried out include Atterberg limit test, compaction, and CBR in unsubmerged conditions. The analysis showed that the soil mixed with 4% clam shell powder without sawdust ash increased the CBR value by 84.32% against the original soil CBR. Soil mixed with clam shell powder and sawdust ash also experienced an increase in bearing strength but not as good as soil mixed with clam shell powder alone.

Abstract

The number of poor people in Indonesia in March 2021 was 27.54 million people. One indicator is that people do not yet have decent homes. The income of the poor is generally below average, resulting in difficulties in accessing housing loans from banks. All parties must contribute in helping the poor to have livable houses. Researchers innovate to make simple houses livable based on Appropriate Technology, namely technically meeting safety, economical and affordable, ergonomic according to occupant anthropometry, fulfilling socio-cultural standards so that they can be accepted by the community and are energy efficient and sustainable. The innovation of using panels or bricks from sawdust for the walls of a simple house with a size of 3 m x 6 m that was built according to Appropriate Technology methods meets feasibility. The maximum stress ratio of 0.534 occurs in the column and is smaller than the required 1.0. The maximum deviation that occurs at the top of the building is 5.91 mm and is smaller than 0.02 times the total height of the building, namely 0.02 times 4000 is 80 mm. Measurement of the intensity of natural lighting during the day obtained 338 Lux, room temperature obtained 25.56°C, air humidity (RH) 71.62%, and air movement 0.15 m/sec and noise 36.82 dB. The contribution of this research is to provide a new wall material solution for simple houses, namely walls made from panels and bricks made from wood powder.

Abstract

Structural health monitoring system is one of the most interesting and important topics in civil engineering. This is because a good structural health monitoring system will increase the reliability of the structure. There are 4 (four) levels in the structural health monitoring system, one of which is damage localization. Damage localization requires an approach or method that can accurately predict the damaged member. One of the methods that is widely applied and proven to give good results for predicting damaged members called damage locating vector (DLV). The DLV method has been applied to several structures, such as plane truss structures, space truss structures, plane frame structures, shear buildings, plane stress elements, thick plate elements and several types of structures. The purpose of this research is to apply DLV method to space frame structures to find out the effectiveness of this method in damage detection. There are three damage scenarios used, two single damage scenarios and one multiple damage scenario. Based on the results obtained, the DLV method can accurately determine the damaged member in the space frame structure for single damage scenarios but in case of multiple damage scenarios, the DLV cannot predict the damaged member due to the values ​​of the end forces and moments of the damaged members are similar to one another.

Abstract

Indonesia's increasing population and limited land have made the need for shelter, workplaces, and vertical buildings increase. As a consequence, buildings that have exceeded their service life, have changed their function, have been damaged by a disaster, and are not fit for function need to be demolished. Demolition needs special attention because the process requires complex planning, is hidden, carries high risks, and generates more than 40% of the total solid waste in developing countries. In Indonesia in particular, deconstruction has not been carried out by many demolition service providers. The government does not yet have comprehensive regulations for sustainable building demolition. This study aims to propose a sustainable demolition model by prioritizing the conservation of demolition waste material. In this study, the "reverse 4D BIM" technology is used to visualize the sequencing of the demolition process and predict the type, volume, and scheduling of disposal of demolition waste. The predicted results of demolition waste are then classified for their use using reduce, reuse, and recycle (3R) concept to maximize the sustainability of the demolition process and the circular economy. To implement this model, a 4D BIM-based building simulation is used. The simulation results show that the proposed model is effective and can be implemented for sustainable building demolition.

Abstract

Nowadays, environmental issues in construction project activities that were previously ignored have become major problems as they trigger global warming. Consequently, green construction as a concept of sustainable development has begun to be implemented. It is sort of an effort to minimize the impact of damage to the environment. The construction project of the Tulungagung-Trenggalek southern route carried out material recycling from construction waste to top foundation layer material. The material processing will have an impact on the construction implementation. Therefore, it is necessary to have a study on a comparative analysis of costs, time, and environmental impacts on the work of the top layer using recycled materials and the cut-and-fill method. After using recycled materials, the cost was IDR 2,637,312,551.00, while the cut-and-fill method cost was IDR 2,535,283,401.00. The recycling method took 20 days, whereas the cut-and-fill method took 37 days. Material waste reached 5729.27 tons by the recycle method and 46586.82 tons by the cut-and-fill method. The recycling method caused emissions of 52774.4 kgCO2/liter, while the cut-and-fill method brought in 59935.34 kgCO2/liter. In conclusion, the recycling method can be categorized as a green construction method because it produces fewer emissions and waste than the cut-and-fill method. The recycling method can reduce the impact of environmental damage.

Abstract

Application lean six sigma (LSS) in West Java is still more often used in the manufacturing industry, in order to provide good product quality for customer satisfaction. Therefore, this study aims to determine how far the application of LSS in West Java has been applied to the construction industry and to find out whether there are differences between each company's qualifications regarding how to control material waste, time waste and cost waste in construction projects after controlling LSS. The method used to answer the purpose of implementing LSS is a descriptive statistical test. While the methods used for different ways of controlling the wastage of materials, time and costs are Multivariate Analysis of Covariance (MANCOVA). The results of the descriptive statistical tests show that the application of LSS to large companies is included in the Very Good criteria (BS) with a score of 82%, for medium-sized companies it gets a value of 75% and small companies with a value of 74%, which means that its application is included in the Good criteria (B). The MANCOVA test results show that there is a difference between large and medium-sized companies in controlling material wastage. There is a difference between large and medium-sized companies in controlling time wastage. There is a difference between large companies and small companies in controlling time wastage. As for the wastage of costs, each company's qualifications in West Java do not have significant differences.

Abstract

Bendungan Bulango Ulu merupakan salah satu proyek strategis yang dibangun di Desa Tuloa, Kecamatan Bulango Utara, Kabupaten Bone Bolango, Provinsi Gorontalo. Dalam membangun sebuah bendungan, analisis geologi dan kestabilan lereng menjadi sangat penting untuk menghindari risiko keruntuhan atau kegagalan struktur. Penelitian ini bertujuan untuk melakukan analisis geologi dan kestabilan lereng pada Bendungan Bulango Ulu dengan menggunakan metode kinematika. Metode kinematika digunakan untuk mengetahui tipe gerakan tanah pada lereng bendungan dan mengidentifikasi nilai probabilitas keruntuhan. Data geologi terkait dengan jenis litologi, petrografi, struktur geologi dan geomorfologi dikumpulkan melalui pengamatan langsung dan di laboratorium. Kemudian, data tersebut digunakan untuk mengetahui kondisi geologi, struktur geologi dan geomorfologi yang kemudian diinterpretasi hubungannya dengan kestabilan lereng. Hasil penelitian menunjukkan bahwa satuan geomorfologi yaitu satuan dataran alluvial dan perbukitan rendah structural. Litologi penyusun lereng bendungan bulango ulu tersusun dari satuan alluvial dan satuan granodiorite. Struktur geologi yang berkembang berupa kekar tarik dengan arah umum timur-barat (E-W) dan dipotong oleh kekar tension dengan arah umum utara-selatan (N-S). Tipe dan probabilitas gerakan tanah yang terjadi berdasarkan segmen yaitu pada lereng segmen A-B berupa Wedge (21.65 %), lereng segmen C-D berupa Wedge (12.27%), lereng segmen E-F berupa Wedge (15,12%), dan lereng segmen G-H berupa Wedge (21,8 %). Berdasarkan dari hasil analisis kinematika, lereng yang berada pada bendungan Bulango Ulu masuk kategori stabil. Penelitian ini merekomendasikan bahwa tidak perlu untuk melakukan perubahan geometri pada lereng bendungan dikarenakan lereng dalam keadaan stabil.

Abstract

The behavior of regular and irregular building structures in resisting earthquake loads will certainly be different, so structural modeling must be done in such a way as to form a safe structure. The building in this study is L-shaped with an area of 2079.52 m2 with 6 floors and 28 m of total height. Earthquake load modeling in this study uses the equivalent static analysis method and design spectrum response about SNI concrete 2847-2019 and SNI earthquake 1726-2019. This study aims to investigate the behavior of multilevel reinforced concrete structures that experience horizontal and vertical irregularities due to earthquake loads as seen from the displacement and drift ratios that occurs is based on the results of numerical analysis. Based on the results of research on the geometry of the structure with vertical irregularities, it shows that the structure does not have Type 1a, Type 1b, Type 2, Type 3, Type 4, Type 5a and Type 5b irregularities. Thus the structure can be planned without considering the requirements to satisfy vertical irregularities. The geometry of the structure with horizontal irregularities shows that the structure has no irregularities in Type 1a, Type 1b, Type 3, Type 4 and Type 5. Meanwhile in Type 2 the structure is stated to have irregular inside angles, so the design force of the diaphragm on the structure must be increased by 25% at the planning stage.
