Instrumen Derivatif: Pengenalan Dalam Strategi Manajemen Risiko Perusahaan

Recent investment inflows through the capital and money market has begun to stimulate the Indonesian economy. New investment instruments are offered by the capital market for the purpose of accomodating investor's risk dan return preferences. Besides stocks and bonds as the primary securities in the capital market, the Indonesian government also issued long-term bonds as its means to obtain capital funds from investors. Derivative securities, such as options and futures, are contractual agreement between two parties to deliver and purchase some specified amount of financial assets or commodity at a specified date and specified price. Option contracts give its holder the right, not the obligation, to do something; while futures contract obligates the transacting parties to perform or fulfill the contract agreement. This paper discusses definition, terminologies related to derivative, profit profile and the use of derivative instruments in the company's hedging strategy. It is essential to note that companies may use different underlying instruments to hedge, such as commodities, gold, stock index, interest rate, and currency

The calculation shows that the part can endure the force from steady load, with the estimated cyclic load of 70,723 cycles. But for live load, the stress and strain will be happening around the yield strength and offset yield strength and the estimated cyclic load declining significantly to 6,358.6 cycles. Furthermore, the shock load result stated that the stress and the strain are exceeding the yield strength and reduces the estimated cyclic load to 1,843.9 cycles. In conclusion, the material is proven to be safe for USAge as the Spare Wheel Carrier manufacturing material.Keywords. spare wheel carrier, SAPH 440, stress, strain, deformation, cyclic loa

Analisa Aerodinamika Body Mobil Hemat Bahan Bakar Antawirya Konsep 3 Dengan Menggunakan Metode Computational Fluid Dynamics

Fuel oil declining from year to year since oil resources of the earth are not renewable. Hence, a fuel saving plan is something of considerable importance today. Continued development of technology has enabled automotive engineers to place an emphasis on vehicle fuel consumption by keeping the drag coefficient (Cd) value to minimum, which in turn should improve fuel efficiency. This research is aimed at effort to prouce a more aerodynamic car body design, particularly to redesign the previous Antawirya car known as Antawirya Konsep 3, to simulate and compare the results of both cars, in term of the drag coefficient values, and to learn about the air flow pattern around the car. Car aerodynamics simulation are conducted in wind tunnel set as the computing domain by Computational Fluid Dynamics (CFD). The k-epsilon turbulent realizable standard wall function method is used in this research, which is specified based on the phenomenon of validation in backward-facing step. This research also use the second order upwind as the discretization method for more accurate results. The number of each grid for previous Antawirya and Antawirya konsep 3 are 862391 and 639641. The results of the simulation show a reduction of drag coefficient on Antawirya konsep 3 compare to the previous Antawirya. Drag coefficient has shown a decrease by 24,93% at a rate of 10 km/h, a decrease by 25,20% at 20 km/h, a decrease by 26,01% at 30 km/h, a decrease by 26,02% at 40 km/h, a decrease by 26,37% at 50 km/h, and a decrease by 25,83% at 60 km/h. The separation and wake phenomenon also occurred on the back of the car body, as the separation and wake on Antawirya konsep 3 are shorter than the previous Antawirya design. This is due to the fact that the body of Antawirya konsep 3 has a more aerodynamic

Macrophage Phenotypes in Degenerative Joint Diseases

Macrophages are plastic cells and depending on their phenotype can contribute to the inflammatory state of tissues. The main objective of this thesis is to explore the involvement of macrophages, in particular the role of their phenotypes, during processes of joint degeneration. The answers of the following questions contribute to the main objective: • How are macrophages of different phenotypes involved in inflammatory tissue degeneration and degenerative joint disease? • How can modulation of macrophage phenotypes be applied to control either inflammation or their response to biomaterials? The work described in this thesis revealed that pro-inflammatory, anti-inflammatory, and tissue repair macrophages each have their own behavior and association with OA development and progression. The studies in this thesis present methods on specifically modulating a macrophage phenotype within tissue with the ultimate goal: suppressing OA progression. These methods can be interpreted as guidelines for selecting the most suitable approach for modulation while taking into account the stage of the disease, the inflammatory state of the tissue, or the type of biomaterial in case of biomaterial based joint tissue regeneration. The knowledge can be applied to use macrophage phenotype modulation as a t
