Logistics Transportation in supporting Logistics movement in urban areas has very limited space for certain road segments, especially for large trucks and container vehicles. The limited space of movement will determine the effectiveness and efficiency of Logistics transportation itself. Logistics travel from to and from trading locations, finally reaching consumers is not a simple matter, but is influenced by the various chain of movements that affect costs, time, security and safety. The factors that influence the pattern of distribution of freight transport in Kendari City, Types of modes of commercial goods transportation, Road networks and supporting infrastructure, Land use Patterns.

Slag nickel is a by-product which causes environmental degradation and conventional slag is widely used as coarse aggregate in concrete. This research, therefore, used the newest slag type (FeNi4) from PT Antam Pomalaa as fine aggregate in natural sand and determine the effect of the combination on the optimum compressive strength of concrete. Moreover, the results obtained were compared with the use of only natural sand in concrete. The procedure involved varying the percentage of the slag mixed with the natural sand by weight at 0%, 25%, 50%, 75%, and 100% with each sample designed to have minimum compressive strength higher than 20 MPa at 28 days. Furthermore, a compressive strength test was conducted to determine the optimum combination to achieve the best value and the results showed 25% of nickel slag variation to be the best while other variations, 50%, 75%, and 100%, experienced a reduction of 8.96%, 11.85%, and 12.19% respectively in comparison with the normal concrete. This, therefore, means the use of Ferro-nickel slag (FeNi4) has the ability to increase the strength and reduce the weight of concrete.

The effects of splitter plate as a passive turbulence control on the transverse vibration characteristics of a cantilevered rectangular prism with the different finite length (aspect ratio L/H) and depth ratios (side ratio D/H of 0.2 and 0.5) was investigated in a water tunnel. A splitter plate was installed behind the prism with a small gap and sufficient length to prevent vortex shedding intrusion. It enhances the response amplitude ascended linearly with respect to non-dimensional velocity. In the case of the prisms with critical points, interferences of amplitude signal spectra for the period of displacement vanished, yielding a uniform waveform on the response amplitude. Inserting a splitter plate improves the increment rate of the dynamic response of the test models. A brief numerical calculation was performed to find the quantities of flow features around a plain and rectangular prism with a detached splitter plate. The alteration of flow wake characteristics is found by diminishing unsymmetrical vortices shedding and reduce flow entrainment at the trailing edge. The essential findings of the prism with a detached splitter plate are the base pressure improvement, reducing drag force, and vanishing sharp peaks of wake FFT spectra.

The urban challenge in realizing a green city for the purpose of a sustainable city is air pollution resulting from vehicle emissions (Carbon monoxide/ CO2). Reducing vehicle emissions can be done by providing green open spaces. In Kendari City, a potential area for the development of green open space is the Bahteramas General Hospital. Activities in the area and around the Bahteramas General Hospital in Kendari City are quite high so that they contribute to emissions (CO2). The object of research analysis is the number of vehicles (daily traffic), the capacity of electricity use, the area of the Bahteramas General Hospital and the area of the existing green open space. The results showed that the type of vehicle that contributes high to CO2 is a motorcycle. The use of fuel as a source of emission (CO2) which contributes to premium types of greenhouse gases, diesel and the use of electrical energy. The absorption capacity of the existing green open space has not been able to reduce CO2 emissions, so it is necessary to expand the green open space to control greenhouse gases.
