ABSTRACT One materials that has potential for bone implants and has a resemblance to the original bone is a 3D bone replica made from porous hydroxyapatitite (HAp). Stacrh Consolidation is one of the methods for making bone replica based on HAp. The purpose of this study was to determine the effect of variations in the addition of wheat flour to the characteristics of porous HAp. This research…
ABSTRACT Bone replicas are bones made to be used as implant models. One technique for making bone replicas was starch consolidation. The purpose of this study was to determine the effect of variations in the addition of cornstarch on the characteristics of the bone replicas produced. This research was conducted by mixing 20 grams of HAp with the addition of 8 grams, 10 grams and 12 grams o…

ABSTRACT Lightweight brick is one of the materials used as a partition wall to replace traditional red brick. The use of lightweight bricks replaces red bricks because they have a lighter weight so the use of lightweight bricks as partition walls will reduce the building's own weight. However, due to its lighter weight, the lightweight brick becomes brittle, affecting its strength. For this re…
ABSTRACT Numerical modelling of helical pile test in peat soil is rarely to be found. The research aimed to analyze the effect of different variation of helical pile spacing, number and diameter using numerical method. Analysis was focused to bearing capacity and failure mode of helical pile in peat soil. Bearing capacity was interpreted with Terzaghi method and Tangent Intersection Method. Th…
ABSTRACT Peat beaches are beaches whose land can be easily abraded than beaches with other types of land. This is due to the light density of peat soil so that it can be easily carried away by the flow of sea water. One of the peat beaches in Indonesia whose coastline has changed significantly in recent decades is the peat beach on Bengkalis Island, Riau Province. Peat samples were taken fro…

ABSTRACT The internet network is very important for the community, because currently people carry out all activities in their respective homes. The National Road is a road located in Buluh Kasap Village, East Dumai District, Dumai City. The majority of the population is of lower middle income, some have even been laid off from their place of work, and many children are still in school who need…
ABSTRACT The condition of overloading the power transformer and exposure to an ambient temperature above the standardiwill cause thermaliaging of the insulationion the power transformer, and aging of the thermal insulation will cause a reduction in the life of the power transformer. Based on the fact that abnormal conditions in the power transformer are caused by overloading, it is important t…
ABSTRACT Free Space Optic (FSO) is a high-speed wireless communication system with an easy and inexpensive installation process and has wide bandwidth, high data rate capacity, high security. So that it becomes one way to replace wired optical communication by performing wireless optical communication and has the potential of a transmission system to achieve the ability to multiply users w…
ABSTRACT Baker's yeast or also known as yeast is a leavening agent in the manufacture of bread containing microorganisms of the type Saccharomyces cerevisiae. The use of yeast in bread making is known to be practical and easy, but yeast intolerance is not uncommon. Instead, natural yeast is used to solve the problem. This natural yeast (fresh yeast) has several benefits such as enriching t…

ABSTRACT Currently, many companies still use conventional methods as floor slab, where in this conventional floor slab work uses wood as the formwork and take a long time in the process of working on it. In addition, wood is slowly getting harder to get and the price is also expensive. For this reason, we need other technological alternatives to minimize the use of wood. One alternative to woo…
ABSTRACT With the continued increase in rice productivity in Indonesia, it will certainly be comparable to the rice husks produced. The purpose of adding rice husks in this study was to determine the effect of adding rice husks on the quality of the red brick products produced with variations of 0%, 2%, 4%, 6% 8%, and to reduce the weight of the bricks themselves. Making samples of brick test …
Mendol Island coast is a dynamic area because it is directly opposite the Malacca Strait. These dynamic conditions can affect coastal vulnerability. The vulnerability of Mendol Island to changes in sea level rise is caused by several physical factors at sea and on land. Efforts to prevent the impact caused by disasters in coastal areas can be done by conducting a vulnerability analysis of …
Singkep Island is a coastal area. Coastal areas face various pressures and development and change. Therefore, the coast is always changing, including environmental changes that can be caused by human activities. These changes have an impact on changes in the coastline. Considering the condition of residential areas and access to transportation such as roads on the coast, this is considered…
ABSTRAK Coconut shell ash is waste generated from the process of burning coconut shells from the coconut shell industry. Coconut shell ash has the potential to be developed as a partial substitute for cement in the manufacture of mortar because coconut shell ash contains silica which can react with lime to produce CSH which is like cement so as to increase the compressive strength of the morta…
ABSTRACT In general, the compressive strength of concrete is influenced by the composition of the concrete, but it turns out that it is not only influenced by the composition of the concrete, but also by the speed of loading. The effect of variations in axial loading speed on concrete compressive strength value fc' 20.75 MPa will be tested in this study. This test aims to determine the effect …
ABSTRACT Minimum service standards for toll roads consist of several service substances, namely toll road conditions, average travel speed, accessibility, mobility, safety, aid/rescue units and service assistance, environment, and rest areas. Accessibility is a service measure that must be achieved related to the ease of interaction between toll users and facilities on toll roads, namely t…
