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 Waste is the residue of human daily activities or natural processes in solid. Waste is basically a material that is wasted or disposed of a source resulting from human activities or natural processes that have no economic value (Law No. 18, 2008). Waste transportation is an important component in waste management activities. Ministry of Environment and Forestry’s Waste Management Nat…

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 ultimate goal of this project is to charge a lead acid battery with a solar panel voltage source. Battery charging is carried out through a DC-DC converter circuit with a full bridge topology, which functions to convert DC voltage to an adjustable DC voltage. To activate the DC-DC converter circuit, a control circuit is required, consisting of the SG3526 IC, which functions as a r…
ABSTRACT Technology in the field of telecommunications is currently experiencing very rapid development. Several factors are driving this development, including the increasing demand for communication access speed and increased user capacity. 5G technology has many advantages compared to previous technologies, namely data speeds of up to 20 Gbps, network capacity 1,000 times greater than the c…
ABSTRACT Laston Lapis Aus or Asphalt Concrete Wearing Course (AC-WC) is a part that is located on the top layer in the flexible pavement of the highway. This layer is the layer that is most susceptible to damage. This pavement layer is a mixture of several materials including asphalt, coarse aggregate, fine aggregate and (filler). Filler is a filler material that functions to fill the gaps or …
ABSTRACT Global warming caused by greenhouse gases is getting longer and more worrying. Switching from fossil fuels to natural gas is a promising solution, by applying the ANG (Adsorbed Natural Gas) mechanism. An important factor for the success of this mechanism is the selection of the adsorbent used. MOF (Metal Organic Frameworks) has good potential in storing methane gas, but further resear…
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 Induction motor is a type of electric machine that is widely used because it has high reliability and low price. Given its vital role, a good protection system is needed so that it can protect the motor when disturbances such as overcurrent, overvoltage, undervoltage and underfrequency occur which can cause damage to the induction motor. The method used in this study is an experimenta…
ABSTRACT The road is a type of land transportation infrastructure that plays an important role in many sectors. Pavement planning is required in road construction. This study plans a flexible pavement at Jalan Kartini using Manual Desain Perkerasan Jalan 2017. The CESA4 value is 0,734774476 million ESA4 and the CESA5 value is 0,780697881 million ESA5, so that the pavement structure layer is in…
