ABSTRACT One type of pavement layer commonly used in Indonesia is a mixture of Thin Asphalt Concrete (Lataston). A thin layer of asphalt concrete called Hot Rolled Sheet (HRS) consists of two types of mixtures, HRS Foundation (HRS-Base) and HRS Lapis Aus (HRS Wearing Crouse, HRS-WC). HRS mixture consists of coarse aggregate, fine aggregate, asphalt, and filler. Filler is needed to fill the voi…
ABSTRACT Automation machine technology has been developed to help overcome problems in manufacturing performance. One of the machines developed is the delta type 3D printer machine which can be used in various professional fields. In designing a delta robot, several things need to be considered, one of which is the singular condition of the delta robot. This is so that the delta robot can oper…
ABSTRACT Lubricant is an important thing in the working system of the machining. Without the use of lubricants, it will cause friction and cause wear and tear so that energy is wasted and component life is reduced. The types of lubricants that are widely used are synthetic lubricants and mineral oil which are difficult to decompose by the environment, causing environmental damage, and their so…
ABSTRACT Mechanical contact on an object that gets a load or thrust will cause friction. Friction between objects if it occurs continuously causes wear. Bearing is one of the elements that must avoid friction because it can affect the life of the element and the work efficiency of the machine. One way to slow it down is to use lubricant. The science that studies the problem is tribology. Wear …
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…
ABSTRACT The waste problem faced by Indonesia is the biggest problem in the environmental field it is necessary to use it, such as converting it into biogas alternative energy. This study aims to analyze the effect of Starter addition variations on biogas production from Bina Widya campus waste, Riau University using dry anaerobic digestion method. This study uses a variety of starter types to…

A Centralized Domestic Wastewater Management System (SPALDT) has been planned for Pekanbaru City which is located in Rejosari Village, Tenayan Raya District which will serve 5 districts namely Pekanbaru City, Limapuluh, Sail, Senapelan and Sukajadi, namun there are still …
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…

Tilapia is a type of freshwater cultured fish that has good prospects to be developed. To fill the customer’s demand of tilapia, the seed of the fish may be transported from other areas and thus the seed must be transported. During the transportation, however, the seed might be stressed and some of them might be died. To reduce the mortality of the seed during transportation, specific handlin…
