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 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 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…
ABSTRACT The water reservoir monitoring system helps the community to find out the water level in the reservoir to avoid overfilling or lack of water in the reservoir when water is needed. This tool is equipped with NodeMcu Esp32 as a control to process sensor data for measuring distances in reservoirs and relay control on motors that are displayed on the telegram as measurement informatio…
ABSTRACT The author is interested in planning the thickness of rigid pavement on the road for the sake of safety and travel comfort for the surrounding community. in this study, namely how thick rigid pavement is needed on Jalan Beringin, Payung Sekaki Tapung District, Kampar Regency which meets the standards of the 2017 Road Pavement Design Manual. directly in the field for 3 days, namely Wedn…
ABSTRACT Merbau tree sawdust ash is a waste generated from the burning process of sawdust from furniture craftsmen. Sawdust ash has the potential to be developed as a partial substitute for cement in the manufacture of mortar. This study aims to determine the effect of adding wood ash to the compressive strength of mortar. Before making the specimens, the properties were tested on fine aggrega…
ABSTRACT The intersection of Jalan Riau - Jalan Kayu Manis is a three-arm unsignalized intersection in Pekanbaru City and often experiences traffic jams. The purpose of this study was to evaluate the performance of the unsignalized intersection of Riau Street - Kayu Manis Street. The method for calculating the performance of this unsignalized intersection is guided by the MKJI 1997. Based …
ABSTRACT Before the construction of the MDA building of the Al-Muttaqin Mosque, the Budget Plan (RAB) is one of the main processes carried out to determine the total amount of work costs by outlining each work item starting calculating the volume of work, calculating Work Unit Price Analysis (AHSP), calculating detailed Budget Plans (RAB), all of which The calculation refers to the plan drawin…
ABSTRAK In everyday life, many used aluminum cans that are found around us become waste that can interfere with environmental hygiene and it turns out that so far it has not been processed properly by recycling. This is because the largest canned beverage producer in Indonesia is currently lacking in canned waste treatment systems. This final project aims to press used beverage cans with a can…
Abstract At this time the development of the combustion engine is moving towards an environmentally friendly combustion engine which emphasizes the use of lower costs. This is due to the depletion of fossil fuel supplies available in the world. Based on this thought, the developer of a combustion engine that uses fuel that is low in cost and relatively harmless to the environment is carried ou…

ABSTRACT Increasing production and productivity of sugar cane indicates that more bagasse waste will be discharged into the environment. Bagasse is known to contain around 37.65% cellulose which can be utilized as a basic ingredient for various high-value chemical products. This study aims to separate cellulose from bagasse. Separation and purification of cellulose was carried out semi-mechani…
ABSTRACT Used cooking oil is frying oil that contains carcinogenic compounds such as free fatty acids, peroxides and others. To utilize used cooking oil, researchers are interested in recycling used cooking oil by carrying out a purification process using wood charcoal powder as an adsorbent. After the purification process, the oil is used to make liquid bath soap. This study investigates the …
