Abstract: Residential waste contributes up to 55% of the total volume of urban waste such as in Jakarta. It makes the transport process of residential waste to temprorary landfill site (TPS) that has been existed, less efficient. Transporting waste process with garbage cart is depended on the manpower, while with the garbage truck, the vehicle’s width and the use of fossil fuels are the weaknesses. Thus, the design concept of a waste transport vehicle using electric motor as driving source is made which has the same payload capacity as a garbage cart in general. Garbage payload along with the main components must be strongly supported by the vehicle frame, which incidentally serves as the support vehicle. In this study, discussed the optimization of electric waste transport vehicle with the help of 3-dimensional CAD modelling, then simulated with static loading to obtain the results of the stress, displacement with the maximum value and location, and can assign the payload distribution position. With variable of the beam profile shape and its thickness, then obtained the optimal order forms, which frame weighs as light as possible but still robust in supporting given loads, which is frame with a cylindrical hollow profile with diameter of 60.3 mm and thickness of 4 mm .

Abstract: Equestrian sport or horse riding is very popular because not only for sports or hobby, but also for entertainment. The performance racehorse of the is largely determined by the suitability of the characteristics of horseshoes material with horse's hooves. This paper describes the identification of materials and heat treatment process of horseshoe made in local and imported products. Previous publication suggests that horseshoe made in foreign countries provides better performance than domestic products, especially in terms of flexibility of horse motion, durability, speed, and lifetime. Therefore, it is necessary to conduct research that emphasizes the observation of material characteristics, manufacturing and heat treatment process as a first step towards the substitution of imported products. A number of observations have been made on the two types of products:macro and micro observations, heat treatment process analyzes that have been subjected to materials, and mechanical testing. From the test results obtained that imported horseshoe material is low carbon steel with of 0.08 %, while carbon content for local product is 0.17%. Thus, both from the material side and from the side of manufacturing, including heat treatment process, local horseshoe products still need to be developed.

Currently the development trend of composite materials shifts to the reuse of natural fiber (back to nature) as a substitute for synthetic fibers. Measurement of the mechanical properties of fiber (reinforcement) plays an important role in quality control. One of the most important mechanical properties of fiber is its tensile strength. Tensile strength of fiber can be known through tensile test (tensile test). To do tensile test (tensile test) fiber required tensile test machine (tensile test machine). The tensile test equipment used today is a foreign-made commercial tensile test device imported at an exorbitant price. These conditions cause obstacles in the development of basic industries and natural fiber technology. Most laboratories in higher education institutions and other technology research institutions do not have tensile test equipment support. The purpose of this research is to design a natural fiber tensile test apparats which is cheap and easy to operate. The research method using design tool design (design and manufacture). The result of this research is prototype of natural fiber tensile test which has been successfully tested with technical data: 5N loading capacity, calibration curve accuracy: N = 1.052 V and loading rate 0.014 N/s. The result of tensile test to one natural fiber that used abaca fiber obtained the value of tensile strength of an average of 579,90 MPa. The result of tensile test obtained is comparable with the data of tensile test results in existing literatures then there is conformity with the value of tensile strenght. The results of this study are expected to provide benefits for researchers, academics and industry in supporting the development of national natural fiber industry to increase the competitiveness of industries at the international level.

The gas fluidization velocity or superficial gas velocity entering the fluidized bed will affect the fluidization in fluidized bed. If the superficial velocity is below the minimum fluidization velocity then there is no fluidization, and if it is more than it should be then the fluidization characteristic will be different. To obtain the effect of gas fluidization velocity to fluidization characteristics, it had been conducted the research on lab scale fluidized bed using CFD simulation method validated with the experiment data. The simulations used Gidaspow model for drag force and k-ε model for turbulent flow. From the experiments obtained that the minimum fluidization velocity was 0.4 m/s and the pressure drop was around 700 Pa. The simulation results for pressure drop across the bed were close to the experiment data for the gas fluidization velocity equal and bigger than the minimum fluidization velocity. For the velocity below the minimum fluidization velocity, there was the big differences between the simulation results and the experiment, so the simulation results cannot be used. For the fluidization velocity of 0.4 m/s and 0.45 m/s, fluidized bed showed the bubbling phenomena, and the higher velocity showed the bigger bubble. For the fluidization velocity of 0.50 m/s to 0.70 m/s, the fluidized bed showed the turbulent regime. In this regime, the bubble was breaking instead of growing and there was no clear bed surface observed. The simulation result for particle density showed that if the gas velocity was higher, the density of particles at the base of bed was decreasing since many of the particles was moving upwards. The particle density was lower in this regime than that of bubbling regime.
