ABSTRACT Requirment of Drinking water in District of Rumbio Jaya, Kampar Regency comes from wells, river water and tap water where the quality and quantity have not been guaranteed. Community water needs reach 66,0 L/sec in 2039, so it is necessary to plan a drinking water supply system with raw water sources originating from the Kampar River. Based on mass balance analysis, there are units th…
ABSTRACT The Indonesian Institute of Sciences (LIPI) conducted research in 18 major cities in Indonesia. The study stated that as much as 270,000 to 590,000 tons of waste entered the Indonesian Sea, of this amount is generally Styrofoam type waste. Styrofoam waste is more dominant because other plastic waste still has economic value. This study aims to Compare the strength of Paving Blocks wit…
ABSTRACT Sago pulp is waste from the processing of sago starch, which has yet to be utilized optimally. In this study, sago waste was processed into briquettes as an alternative energy source to replace fuel in the household. At the time of burning briquettes will produce pollutant emissions into the air, one of which is Particulate Matter (PM2.5). This study aims to determine the characterist…
ABSTRACT Waste the residue from human activities in the form of solid waste. Waste needs to be managed so as not to cause negative impacts. One of the efforts in managing waste is by carrying out waste transportation. The purpose of this study was to evaluate waste transportation and provide planning related to waste transportation in Payung Sekaki District. The results showed that Payung Seka…
ABSTRACT Waste management of a city aims to serve the waste generated by residents. The current condition of solid waste management is facing a lot of pressure due to the increasing number of waste generators and sources. Therefore it is necessary to do waste management, one of which is waste transportation. The purpose of this research is to evaluate waste transportation and provide planning …
ABSTRACT Meranti Islands Regency is an area with regional conditions dominated by peat soil and has a moderate groundwater quality, with heavy metal content of Pb, Cd and Cu which is high and exceeds quality standards. Therefore, other alternatives are needed to meet raw water needs by utilizing Rainwater Harvesting technology. In this study, the study was conducted in the Meranti Islands Regen…

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.
