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…

Pemetaan Tingkat Kebisingan Pada Jam Puncak Akibat Aktivitas Transportasi Di …

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…

Pengaruh Kecepatan Dan Volume Kendaraan Terhadap Beban Emisi Karbon Monoksida…

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…

Pengaruh Penambahan Kaolin Pada Proses Flokulasi Dalam Pengolahan Air Gambut …

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 …

Perencanaan Sistem Penyediaan Air Minum Di Kecamatan Sungai Sembilan, Kota Dumai

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…

Pengaruh Waktu Pengadukan Cepat Pada Proses Koagulasi Flokulasi Dengan Koagul…

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…

Analisis Pengaruh Tinggi Unggun Briket Pada Kompor Biomassa Yang Mengemisikan…

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…

Pengaruh Variasi Kecepatan Pengadukan Cepat Pada Proses Koagulasi, Flokulasi …

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…

Desain Dan Simulasi Proteksi Motor Induksi Tiga Fasa Menggunakan Software Matlab

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…

Perencanaan Tebal Perkerasan Lentur Menggunakan Manual Desain Perkerasan Jala…

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…

Pengolahan Limbah Padat Industri Tahu Menjadi Pupuk Kompos

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 …
