ABSTRACK One of the weaknesses of the concrete material is that it is easily damaged in aggressive or extreme environments, concluding in seawater. Wet dry cycle mechanism can be used as a simulation of concrete exposed to be attacked by sea water. Shellfish waste that goes through a burning process at 700°C will produce a CaO content of 55.10%, so it has the potential to be a substitute for …
ABSTRACT Initial damage to the structure occurs in the outer layers of the affected surface exposure to the peat environment and the static and dynamic movement of the structure. To prevent structural damage, the latest technological innovations are needed in the use of mortar constituent materials to increase the strength of the mortar. Polymer mortar is a composite material formed from a mix…
ABSTRACT Beams are a rigid part of the structure of a building. This beamis specifically designed to be able to withstand and transfer loads to column. Beams without shear reinforcement will experience changes in behavior both in terms of strength and failure patterns. The purposes of this study were to analyze the behavior of reinforced concrete beams reinforced with the Deep Embedment me…
ABSTRACT Development project activity is an activity whose start and finish schedule has been determined, with the allocation of certain resources and intended to produce a product. If there is a delay in the schedule, it will affect the objectives of the project.

ABSTRACT This research aims to develop the durability of acrylic polymer concrete. In this study, the durability of concrete investigated is concrete strength, concrete impermeability and corrosion of concrete reinforcement. The strength of concrete is shown by testing the compressive strength of concrete and the tensile strength of concrete. The experimental results showed an increase in conc…
ABSTRACT Petroleum production shows a downward trend. Biodiesel is a renewable energy source that can be an alternative fuel similar to conventional (fossil) diesel oil. The use of biodiesel in diesel engines is still experiencing problems and results in the performance of diesel engines not being optimal. Several ways that can be use to improve engine performance in the use of biodiesel inclu…
ABSTRACT Currently, the supply of fossil energy such as oil in Indonesia, which has been used so far, is running low. Therefore, efforts are needed to find renewable energy. One alternative fuel that is environmentally friendly and comes from renewable resources is biodiesel. The biodiesel used is generally mixed with diesel, which is called biodiesel, each biodiesel-solar mixture will have it…
ABSTRACT Fulfilling the need for electrical energy that is not optimal, especially in rural areas, makes it difficult for people to be able to carry out activities like other communities, such as in other areas where electricity has entered the area. The Portable Screw Turbine is a small-scale power plant, where this turbine works by utilizing low head water flow and high water discharge to pr…
ABSTRACT The increasing amount of plastic waste is causing problems for the environment, due to the non-degradable nature of plastic in the soil. One of the plastics that are widely used in everyday life is polyethylene terphthalate (PET). It takes decades in the soil to decompose the wastes from these plastic materials. Another alternative for handling plastic waste is the recycling process w…
