Desain bentuk kendaraan merupakan aspek yang sangat diperhatikan untuk mengoptimalkan engine power yang dihasilkan oleh kendaraan pada saat bergerak dengan kecepatan tertentu. Pada saat kendaraan yang bergerak, separasi aliran akan terjadi pada bagian belakang kendaraan tersebut akibat efek viskos fluida. Fluida kehilangan energi kinetik di permukaan dinding sehingga tidak memiliki momentum yang cukup untuk mengalir dalam lapisan batas. Perubahan kontur secara drastis menyebabkan fluida tidak mampu bergerak mengikuti kontur sehingga mengalami separasi. Salah satu upaya yang dapat dilakukan untuk memodifikasi timbulnya separasi aliran di lapisan batas dari permukaan kendaraan yang berakibat pada terbentuknya aliran balik di sekitar kendaraan adalah penerapan kontrol aktif aliran berupa suction. Penelitian ini bertujuan untuk menganalisis pengaruh suction terhadap medan aliran pada model kendaraan dengan variasi geomteri muka. Model uji yang digunakan adalah adalah reversed Ahmed model dengan variasi sudut kemiringan pada bagian depan () yaitu 25 o , 30 o , dan 35 o. Pada penelitian ini digunakan pendekatan komputasi dengan model tubulensi k-epsilon standard. Kecepatan upstream dan suction yang digunakan adalah masing-masing 16.7 m/s dan 0.5 m/s. Hasil penelitian yang diperoleh menunjukkan bahwa geometri muka dan suction memberikan pengaruh yang signifikan terhadap medan aliran pada bagian belakang model kendaraan, dimana pada model kendaraan dengan geometri muka yang mempunyai sudut kemiringan 25 0 mengalami olakan yang lebih kecil. Sementara, penambahan suction pada kedua sisi samping bagian atas belakang pada model kendaraan dengan geometri muka yang mempunyai sudut kemiringan 30 0 mengalami pengurangan olakan yang lebih besar. Kata kunci: geometri muka, medan aliran, olakan, suction Abstract The flow field around the wake comprises a pair of vortices and trailing vortices that come from the sloping edges of the rear of the vehicle. Design of the shape of vehicle is a highly considered aspect in optimizing engine power generated by the vehicle while moving at a certain speed. As the vehicle moves, the flow separation will occur at the rear of the vehicle due to the viscous effect of the fluid. The fluid loses kinetic energy on the surface of the wall to a condition where there is no sufficient momentum to flow in the boundary layer. Contour changes drastically causing the fluid unable to move along the contour until it underwent separation. An effort that can be made to modify the occurrence of separation of flow in the boundary layer of the surface of the vehicle resulting in the formation of backflow around the vehicle is the application of active control flow in the form of suction. This study aims to analyze the effect of suction on the flow field on the vehicle model with variations of frontal geometry. The test model used was a reversed Ahmed model with variations of inclination angle at the front () of 25 o , 30 o , dan 35 o. In this research, computational approach with standard k-epsilon tubulence model was used. The upstream and suction velocities used are 16.7 m/s and 0.5 m/s respectively. The result of the research shows that the surface and suction geometry give significant influence to the flow field at the rear of the vehicle model, where in the vehicle model with the frontal geometry with a slope angle of 25 o , the model underwent a smaller wake. Meanwhile, with the addition of suction on both sides of the rear upper side of the vehicle model with a frontal geometry with a slope angle of 30 o , the model underwent a larger wake reduction.

PET plastic waste is recycled by heating to a boiling point of approximately 300°C. There are five variations of concrete mixtures, defined the percentage of PET artificial aggregate to the total coarse aggregate, by 0, 25, 50, 75 and 100%. Tests carried out on fresh concrete mixtures are slump, bleeding, and segregation tests. Compressive and flexural strength tests proceeded based on ASTM 39/C39M-99 and ASTM C293-79 standards at the age of 28 days. The results showed that the use of PET artificial aggregate could improve the workability of the concrete mixture. The effect of PET artificial aggregate as a substitute for coarse aggregate on the compressive and flexural strength of concrete is considered very significant. The higher the percentage of PET pl...

Therefore, this research aims to reduce aerodynamic resistance by analyzing the flow pattern characteristics and pressure fields. The method applied to delay separation and reduce longitudinal wake and vortex formation is the passive control in the form of dimples in the separation area. Furthermore, this research was carried out using a 1: 6 ratio of the Reverse to Real Ahmed body model. The computational approach was used to obtain the flow and pressure field characteristics with its aerodynamic resistance validated by experimental testing. Passive control was applied in a dimple configuration and two zigzag lines with ratios of 0.20, 0.25, and 0.50. The results showed that dimples in the vehicle model reduced longitudinal wake and vortex formation by delaying flow separation, increasing pressure efficiency, and reducing the highest aerodynamic...

However, due to the limitations of the company in supplying water, particularly in the dry season, an alternative is required, such as using groundwater without causing over-exploitation. This study aims to determine the optimal rate of groundwater pumping in the coastal aquifer to avoid seawater up coning using SEAWAT V.4 numerical model. The research method was carried out using a GEO-7X GPS device to obtain coordinate's location, land elevation and observation well distance from the coastline. Secondary data in the form of aquifer thickness data and geological map of the site were obtained from previous studies. The salinity test results show that the average salinity value of the ten water samples from observation wells is 36.8 mg/l, which means that the water is categorized as non-saline water (freshwater). These data are in line with the groundwater ut...

The research was conducted in the laboratory on flexural concrete beams with the quality of f´c= 25 MPa. One normal concrete flexural beam (BN) with repetitive load was without seawater and no reinforcement. One flexural beam was without sea water immersion but with GFRP-reinforcement. Another flexural beam reinforced by GFRP sheets is immersed in a pond containing seawater with time variations up to 12 months. The test was performed with a fatigue load of 1.25 Hz frequency to failure. The results showed an increase in capacity due to 58.3% for GFRP-reinforcement. There is a decrease in the capacity of GFRP sheet influenced by seawater immersion. The same trend with the decrease in ductility occurred in the flexural beam to 14% due to seawater immersion. Maximum beam failure repetition occurred at 1,230,000 cycles on b...

The dimples surface helps to overcome turbulent airflow around vehicles, thereby delaying the separation point and producing fewer vertices and drag. This study aims to predict the pressure distribution occurring over the plate surface with the formation of inline dimple rows on the upper back end. The test is carried out with Computational Fluid Dynamic (CFD) FLUENT program. The test model has a dimension of 300 mm in length, 100 mm in width, and dimples ratio (DR) of 0.5. Dimples are arranged inline as much as 1 to 6 rows. Upstream velocities through dimple plates range from 10 m/s to 20 m/s. The results of the study show that the minimum pressure coefficient occurs at the top front of the plate due to the flow separation that occurs at the front end of the plate. At x/L=0.25 x/L=0.5 and x/L=0.75 (before the dimples formation), a flow pattern returns to normal, this c...

That makes research on the aerodynamic drag force on vehicles very important. This study aimed to analyze the effect of active flow control by suction and variations on front geometry towards the reduction of aerodynamic drag as well as pressure coefficients on vehicle models. The research was conducted in computational and experimental approaches. Frontal slant angle variations (() of 25(, 30(and 35(were applied in the study. Computational approach used k-epsilon standard turbulence model. Upstream and suction velocity values used were16.7 m/sand 0.5 m/s, respectively.
