ABSTRACT Fossil fuels are running low and are expected to run out, so the world needs renewable energy. Biomass from Empty Fruit Bunches (EFB) is one of the potential renewable energy. In previous studies, peat water was used to reduce potassium (K) so that potassium oxide (K2O) decreased which can cause slagging and fouling, and torrefaction methods to increase the heating value. Chlorine cau…

ABSTRAK The cultivation of fish seeds is widely practiced by Indonesian people as a livelihood. The farmers usually manually feed the fish by scattering feed in each pond of uncertain size. Not only does this consume time, but manual fish feeding also lacks a regular schedule, resulting in inefficiency. IBased on this problem, the researcher proposed an automatic fish feeder dispenser tool bas…
ABSTRAK A tribometer is an instrument used to measure a tribological quantity consisting of the coefficient of friction, frictional force, and volume of wear between two materials in contact with each other. This final project aims to manufacture and assemble a gear type tribometer and determine the effect of oil (lubricant) on gears. Generally what is related to the Tribometer is testing on ma…

The purpose of this study is to analyze school transportation planning from an economic perspective in Pekanbaru using the cost benefit analysis method. This study calculates the Vehicle Operating Costs (VOC) of school transportation, namely buses, and determines the value of the fare based on technically feasible routes. The VOC value for school transportation planning becomes the Cost val…
In the pulp industry it is often to encounter high energy consumption, some of which is due to sub-optimal equipment design. One of the main findings is pipeline as pulp slurry transportation because the use of empirical correlations is out of scope of application, such as different levels of pulp consistency and average flow velocity are applied. Although the process steps are based on the…
ABSTRACT The development of concrete science in the field of construction is increasingly advanced; concrete is widely used in building works, roads, bridges, and waterworks. The problem with concrete that occurs is seepage in the concrete due to reduced concrete impermeability. The impermeability of concrete is very important to overcome seepage that occurs so that the reinforcement in the co…
ABSTRACT Soil respiration is the main route for the transfer of carbon dioxide (CO2) emissions from ecosystems to the atmosphere which makes it one of the contributors to carbon dioxide (CO2) emissions from the agricultural sector. Activated carbon can improve the physical, chemical, and biological properties of the soil and has the potential to be a useful material for reducing CO2 emissions …
ABSTRACT Industrial growth and the increasing number of transportation causes the need for oil to increase. The increasing need for oil is directly proportional to the waste produced, namely used oil. The use of used oil waste is an environmentally friendly and renewable alternative fuel. This study uses a mixture of used oil and Pertamina Dex fuel which is used as fuel in analyzing exhaust emi…
ABSTRACT The existence of traffic lights plays an important role in regulating traffic to reduce congestion and the number of accidents. The lack of public awareness of the rules is one of the problems that has a very big influence. One of the most common traffic violations we encounter and is committed by motorists is a violation of traffic lights. This study aims to determine the condition o…
Abstract The process of planting rice in general is still done manually, especially as rice planting is carried out by farmers in the Salimpaung District, Tanah Datar Regency, West Sumatra. Planting is usually done by 1-3 people depending on the area of the rice field to be planted with an average spacing of about 23-27 cm. The scarcity of labor in agriculture, especially planting workers, is …

ABSTRACT Shrimp waste in the form of shells, heads and tails which contain protein, can be processed into chitin which has many uses. Chitin is a polymer produced by shellfish (shellfish). Indonesia is one of the largest shrimp producers in the world, where the shell contains chitin compounds as an alternative adsorbent. This compound can be processed and used as an adsorbent for heavy metals.…
ABSTRACT Helmets are used as standard head protection when driving which serves to protect and reduce the impact of head injuries due to accidents involving motorbikes. This study aims to determine the characteristics and opportunities for helmet use in Pekanbaru City, this study uses primary data. Primary data was obtained from direct observation in the field by giving questionnaires to 110 r…
The pulp and paper industry ranks third in water use after the metal and chemical industries. The use of water in the industry impacts the liquid waste produced. The effluent from the pulp and paper industry has a very complex composition. Therefore it is almost impractical to characterise all the components like other industrial wastewater. Based on government regulations, liquid waste di…
