ABSTRACT 1,4-Butanediol (BDO) is a primary alcohol and an organic chemical compound with the formula C4H10O2 which is an important element in a long production chain consisting of various intermediates and their derivatives, and has a colorless and almost odorless hygroscopic liquid with distinct bitter taste. Butanediol is widely used in various industries including electronics, cosmetics, ph…
ABSTRACT The increase in ownership of motorized vehicles has resulted in increased transportation activities. The tendency to increase the number of motorized vehicles operating will increase the traffic load, one example of which is the increase in noise intensity. This study aims to measure noise intensity and map noise at peak hours due to transportation activities that occur at the Soekarn…
ABSTRACT HR Street. Soebrantas is classified as an arterial road that functions for community service activities and distribution within the city. Vehicle activity on this road will affect the amount of air pollutant gas emissions produced from vehicles. The purpose of this study is to determine carbon monoxide (CO) emissions and determine the effect of vehicle speed and volume on carbon monox…
ABSTRACT For people living on peatlands who have not received clean water services, many use peat water as a source of water for daily use, even though they do not meet quality standards. Peat water has a high content of organic matter and color, making it difficult to treat peat water with the usual coagulation-flocculation process. In this study, kaolin was added to the flocculation process …
ABSTRACT Clean water services in Sungai Sembilan District, Dumai City originate from groundwater and rainwater without going through a clear processing process, in which the quality, quantity and continuity of these water sources have not been guaranteed. The maximum daily need for water in Sungai Sembilan District in 2041 will reach 119.1 liters/second. So it is necessary to plan a drinking w…
ABSTRACT Peat water potentially be raw water because plenty of its availability, but peat water has characteristics that do not yet fulfill raw water quality according to PERMENKES RI Number 32 of 2017. Peat water has high natural organic matter and color, so it needs to be carried out with water treatment. One possible treatment is coagulation flocculation using aluminum sulfate which has a c…
ABSTRACT The need for energy sources is increasing along with the increase in energy consumption by the community. This must be immediately balanced with the provision of new renewable energy sources. One step that has been widely researched and developed is biomass. Briquettes are an alternative fuel from biomass utilization. In Indonesia, sago pulp has considerable potential to be used as re…
ABSTRACT Providing clean water is a problem for some residents who live in peat areas, where the raw water, commonly called peat water, has a high organic matter and color content. One of the peat water treatments that can be done is coagulation, flocculation, and sedimentation. This study aims to determine the effect of rapid mixing speed on coagulation, flocculation, and sedimentation proces…
ABSTRACT Solid organic fertilizer is the result of composting from agricultural waste and livestock waste, which contains macro and micro nutrients so that it can improve soil structure. This study aims to obtain a formula that meets the criteria to be achieved in the manufacture of compost from equalizing sludge in tofu waste with a variety of raw materials such as rice husks and sawdust and …

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…
ABSTRACT Pekanbaru City's wastewater access coverage consists of 90% local systems, 7.59% babs and 2.41% inadequate access. 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 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…
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…
