<![CDATA[Abstract: A numerical simulation of single droplet phenomena is conducted using a finite volume method. Interface between different phases is tracked by using a front-tracking method. Governing equations used in present paper consist of the continuity equation, the Navier-Stokes equation and the front-tracking equation. The unsteady Navier-Stokes equations are solved implicitly using the finite volume method on staggered mesh. The interfacial term such as surface tension is negligible and the viscosity of the fluid is considered equal. The completion of pressure term is solved by Successive Over-Relaxation (SOR) method. The validation of present paper result is conducted by comparing to Tryggvasson (2012) result using explicit scheme. The advantage of this research is using implicit scheme that is unconditional stable. This research is the initial step to model a single droplet impact on solid surface. In this research will be discussed representation of interface and dynamics of interface reconstruction. Finite volume and front-tracking methods are expected to perform the problem well for more complete case. ]]>

<![CDATA[This paper presents the results of advanced work as a continuation of previous observations about the identification of material and process of the horseshoe fabrication for racehorses as published in the “Jurnal Poros Vol. 15 No. 2, November 2017”. This further research is more focused on the evolution of microstructure and the value of hardness as a function of deformation degree variations of the forging process for horseshoes and horse nails. This is performed to investigate how much degree of deformation can produce form, type and phase distribution on the microstructure and the value of hardness that are relevant to the characteristics of imported products. Through this stage, the material characteristics of imported products can be approached and obtained from the local products. Thus, the quality of horseshoes and horse nails similar to imported products are expected to be able to fabricate in the local SME (Small Medium Enterprise). From the microstructure aspect, there are differences in grain shapes for Local, Australian and Swedish products because the grain forms fabricated in Sweden and Australia are more elongated than local products. This represents that the value of hardness is higher than local products except products fabricated in Australia. Local product nails have better grain because they are more equiaxial and have finer grains so that they have a high hardness value and better toughness compared to imported products. Local horseshoe show a much lower value of hardness compared to imported products. There is a peculiarity in the horseshoe because the hardness value decreases when the degree of deformation increases that is from the percentage of the work process 20% to 80%. From the microstructure of the horseshoe, the increasing deformation degree of the work process percentage 20% to 80%, the grain size is coarser and the grain size is smoother back when the percentage of the work process reaches 100%. This is proven when the percentage of the work process reaches 100%, the value of hardness increases to 147 VHN.]]>

<![CDATA[Abstrak: Otomasi industri merupakan hal yang tidak bisa dihindari untuk meningkatkan produktifitas, kualitas dan keselamatan. Oleh karena itu, simulasi mesin otomasi sangatlah penting untuk dibuat agar sistem kerjanya dapat diketahui secara pasti dan dapat dipastikan aman bagi operator. Proses yang biasa digantikan dengan otomasi adalah proses pemindahan barang dan proses pengecekan, sehingga sudah tidak membutuhkan tenaga manual lagi. Modul Storage Station adalah bagian dari mesin simulasi untuk pengecekan. Dibutuhkan PLC untuk mengontrol kedua modul tersebut sehingga dapat berjalan sesuai dengan yang diinginkan. Salah satu bahasa pemrograman yang mudah dimengerti adalah Functional Block Diagram (FBD). Pada FBD, terdapat sebuah metode yaitu metode Sequential Function Chart (SFC) untuk mengatur urutan kerja dari program. Penelitian ini membahas mengenai pengendalian modul Storage Station yang menggunakan bahasa pemrograman FBD dengan menggunakan metode SFC. Hasil yang didapatkan adalah mesin simulasi untuk modul Storage Station dalam skala laboratorium yang mampu mendeteksi material, warna, dan lubang dari benda kerja beserta diagram gerakan dari masing-masing modul. ]]>

<![CDATA[Strand Test Facility has been constructed and will be used for passive reactor core cooling simulation research without using a pump or outside force, so that the movement of water flow occurs naturally. One important component of the FASSIP-02 is the water cooling tank (WCT), in addition to piping, expansion tanks (ET) and water heating tanks (WHT). WCT containing water such as a pond that functions to take heat in the water from the FASSIP-02 piping system with a position at an altitude of 11 meters. The total load of water and tank is 10 tons and for safety and security factors during operation it is necessary to analyze the mechanical strength of the WCT. Analysis is done by simulating mechanical stress conditions and translational displacement to determine the safety of WCT when operating. The stages of analysis include making a 3-dimensional model equipped with the mechanical properties of the material used, giving a load on the 3-dimensional WCT model, giving restrain to simulate the stable condition of the 3-dimensional model and testing it in simulation. The results of the analysis show that the mechanical stress on the WCT is still in the elastic area of the Carbon Steel AISI 1040 material if the temperature of the secondary water in WCT is less than 90 ° C. The primary water operating temperature is a maximum of 90 ° C and the secondary water temperature does not reach 90 ° C due to heat transfer from primary to secondary. Translational displacement that occurs is very small when compared to the WCT dimension so that it does not result in a change in shape in the WCT. Thus the design of the WCT can be continued to be constructed and safely operated.]]>
