Abstract

Indonesia, as a developing country, has many slum areas. Over the years, there have been many projects specifically targeting the improvement of slum areas, both at a national or regional level. One example of such project can be observed in Malang City, East Java, where visual improvements of a slum area is attempted by the application of colorfull paints throughout the settlements. Two of the initial projects are Jodipan and Ksatrian Village that are located on the riverside area of Brantas River, one of the biggest river in East Java. The original idea firstly came to Jodipan Village to improve the cleanliness of the area. As the Jodipan Village improved, this village became a local tourism area. Due to its success, the painting project was then adopted to the Ksatrian Village across the river. Before the project, the residents of the villages were used to throw their municipal solid waste to the river. Since the improvement projects ran, it has been found that the improvement can be linked to residents’ awareness for municipal solid waste management. This study focuses on the correlation of visual improvement and behavior change of municipal solid waste; and the differences between the correlations in each village (Jodipan and Ksatrian). A descriptive model was done by observation and questionnaire to the 48 residents of Jodipan Village and 69 residents of Ksatrian Village, with a tolerance for error of 0,1 and confidence level of 90%.

Abstract

In recent years there have been several occasions of failure of non-buildings such as billboard towers and pedestrian bridges around high-rise areas in urban Indonesia. Most cases did not occur during any particular high-speed wind gusts but rather during normal wind speed. This research aimed to show the increase in wind load for structures built between high-rise buildings. A simplified cluster of 4 symmetrical high-rise building was investigated. The study used a wind tunnel and a Particle Image Velocimetry (PIV) device in the experiment. Several angles of attack and also different distances between buildings were investigated to see the impact of these parameters on the wind flow between the buildings. Wind flow experiences an interaction flow in all central areas, which translates into an increase in speed. The change in distance between buildings changes the behavior of the flow in the cross area while a change in the angle of attack of the wind does not influence the amplification factor. The results show that there was an increase from 7 to 44% in wind speed due to the street canyons and that the highest amplification occurred with an angle of attack of 0°.

Abstract

Beban angin di sekitar bangunan dapat mengalami amplifikasi yang mungkin menyebabkan kegagalan struktur, sehingga penting untuk memahami perilaku aliran fluida di antara bangunan. Dalam studi ini dilakukan pemodelan fluida dengan menggunakan RANS, sebuah metode computational fluid dynamics (CFD) yang memiliki waktu komputasi lebih cepat dari metode lain. Dalam studi ini digunakan program OpenFOAM yang merupakan program open source. Pemodelan dilakukan dengan menggunakan structured mesh dan untuk pemodelan turbulensi yang terjadi menggunakan metode RANS standard k-ε. Model dari kasus yang dipelajari merupakan 4 bangunan simetris dengan skala 1:420. Pemodelan numerik dilakukan dengan mengubah ukuran domain komputasi dan tingkat kehalusan meshing yang berbeda. Hasil penelitian menunjukkan domain komputasi memiliki pengaruh yang signifikan dalam melakukan CFD dimana nilai eror pada daerah aliran yang memiliki ratio kecepatan aliran yang tinggi (  >1) sehingga masuk dalam batasan eror yang dapat diterima. Sedangkan untuk perubahan tingkat meshing tidak memberikan perubahan eror yang signifikan, di mana dengan meshing relatif kasar dan memiliki waktu komputasi yang lebih cepat dapat menghasilkan hasil yang mirip dengan pemodelan yang menggunakan meshing lebih halus dan membutuhkan waktu komputasi yang besar.

Abstract

In fluid dynamics analysis, one of the things to do is to perform numerical modeling validated on the resultsof experimentation. In numerical modeling of wind flow there are several forms of modeling used includingRANS, LES, DNS, etc. where the modeling has its own advantages and disadvantages. Among these models,RANS is a model that has the cheapest computer expense compared to other models so that it has the highestworkability. Therefore, rans method testing (Reynolds Averaged Navier Stokes) was conducted to determinethe capability of turbulence models in checking wind speed contours on the road between 4 simplesymmetrical tall buildings with 0o, 30o, and 45o attack an gles validated with the results ofexperimentation. This research was conducted using RANS modeling (Reynolds Averaged Navier Stokes) andstandard turbulence model k-ε and validated using Low Speed Wind Tunnel and PIV (Particle ImageVelocimetry). According to the results of the test, U/Uo wind speed conditions obtained in wind modelingwith RANS and k-ε standards have errors that are still acceptable.

Abstract

Wind gusts (gusts) are sudden increases in wind speed that potentially cause severe damage to infrastructure. Gusts occur within several seconds but numerical weather models typically predict future wind with a time step of tens of seconds or minutes. Therefore, a parameterization is needed to estimate gust. Gusts can be produced convectively and non-convectively depending on the presense of thunderstorm. The gust parameterization schemes may perform differently in both cases. In this study, five wind gust parameterization schemes were evaluated at the Kertajati International Airport. Based on simulations of three convective gust and three non-convective gust events using several evaluation metrics, we find that the best scheme for non-convectively driven gusts is the Turbulent Kinetic Energy (TKE) scheme, while the Hybrid scheme performs best for convectively driven gusts. However, the performance of Hybrid scheme during non-convective event is not so far behind TKE scheme. The Hybrid scheme was developed to work on both non-convective and convective events and this capability is evidently shown. The result could be useful to develop mitigation measures for strong wind incident that frequently occurs in Indonesia.

Abstract

Slum areas in Pontianak, such as the Panglima A. Rani and Kayu Manis areas along the Kapuas River, face significant domestic wastewater management challenges, including river pollution and health issues. To meet the SDGs 2030, the city government plans to implement a domestic wastewater management system using both centralised and localised approaches. In this study, the Unified Theory of Acceptance and Use of Technology (UTAUT) and structural equation modelling (SEM) are used to analyse the factors influencing the acceptance of sanitation technologies. The research includes both quantitative and qualitative analyses using PLS-SEM in Smart PLS V.3.0. The results indicate that performance expectancy, effort expectancy, social influence and facilitating conditions influence community acceptance, with the highest path coefficients observed for facilitating conditions (41.26%), followed by social influence (32.19%), effort expectancy (21.46%) and performance expectancy (5.09%). Facilitating conditions and social influence have a significant impact on community participation, with P-values < 0.05 and T-statistic values > 1.96.
