Abstract

ABSTRACT Wells are one of the means of providing clean water originating from the soil layer which is relatively close to the surface of the ground, so it needs attention because it is easily contaminated and contaminated through seepage. Especially if the construction of the dug well does not meet the requirements. The use of clean water facilities with dug wells was also carried out by the community around TPA II in the Karya Jaya Musi 2 Village of Palembang. This study aims to determine whether the variables of odor, color, TDS, pH and salinity of dug well water around TPA II in Karya Jaya Musi 2 Palembang village meet the quality standards in accordance with Minister of Health Regulation No. 32 of 2017. Several procedures in this study include: two test parameters are physical parameters which include odor, color and total dissolved solids (TDS) and chemical parameters, namely salinity and acidity (pH). The results of the physical parameter analysis showed that the dug well water smelled, colored and had a total dissolved solids of 3.182 mg / l, while the results of the chemical parameter test were pH 5 and salinity 22 ppt. The test results showed that the quality of well water dug in the variables of odor, color, TDS, pH and salinity around the landfill did not meet the quality standard according to Permenkes RI No. 32 of 2017.

Abstract

ABSTRACT Well water is a source of water that is used by the community around the landfill for everyday life. The well water is not far from the landfill site. Based on observations the environment around the TPA is very dirty and there are puddles of water, so it is not good for residents who are around TPA to use well water for their daily lives. Some simple methods can be done to determine the condition of well water, one of which is by simple physical and chemical testing. Simple physics tests are carried out by looking at changes in color, turbidity, and odor while chemical tests are carried out by mixing sample solutions with tea. In the physical and chemical test of the well water of the residents around the TPA 2 in Palembang, it can be concluded that the well water around the TPA has a cloudy color, a strong odor and a pH of 7.

Abstract

ABSTRACT Industrial liquid waste PT Pupuk Sriwidjaja (Pusri) Palembang, contain Nitrogen compounds, in the form of ammonia. The liquid waste is derived from a small canal – canal flows from the unit, the unit of urea and ammonia unit utilities, before being processed to be discarded into the Musi River. One of the canals that connected on 3 of these units and empties into the Musi River is a canal 32, also known as K-32. This research aims to know the implementation of the control of environmental pollution, by analyzing the water quality of waste based on the levels of ammonia and pH. The methods used in the research is qualitative and quantitative methods, by looking at the color change in the sample which has reacted with reagent Nessler, and using UV-Vis Spectrophotometer instrument in order to find out the levels of ammonia on liquid waste. Based on the results of the study, the average pH obtained on channel 32 (K-32) is 8.52, while average levels of ammonia was 58.92 ppm (0.05 in kg/tons). All of the result were in quality standard based on Ministry regulation no. 5 which issued in 2014. Keywords : Ammonia; Liquid Waste; pH; Reagent Nessler; Spektrofotometer UV-Vis

Abstract

ABSTRACT Water is a liquid that has no taste, smell and color and consists of hydrogen and oxygen with the H2O chemical formula. Because water has properties that can be used for almost anything, water is the most important substance for all life forms (plants, animals, and humans), until now, besides the sun which is an energy source. The purpose of the analysis is to find out the color, smell and pH of the water found around Palembang's Musi 2 landfill. This research is descriptive qualitative, which describes the results of the comparison of water quality data from laboratory tests with applicable quality standards and describes the results of the study based on the study of literature. the water around the Palembang Musi 2 TPA has a pH level of 6 and 8, yellow and black, and foul-smelling. This result does not meet the characteristics of water that can be consumed according to the Regulation of the Minister of Health of the Republic of Indonesia No. 492 / Menkes / Per / IV / 2010. Keywords: color; pH; smell; Water.

Abstract

ABSTRAK Making briquettes from plastic waste and paper waste can make briquettes as an alternative uel . The purpose of this study was to find out how the resulting heat value produced from plastic waste briquettes through fuel test. The plastic waste obtained is burned to form. Plastic in the form of further granules mixed with 10% starch 1:1 dan 2:1 (plastic waste : paper waste). The material is printed using a mineral cup, then dried under the sun for three day. The calorific value produced from plastic waste briquettes through cooking water as much as 200 gram produces 60-62 oC heat.

Abstract

ABSTRACT Inherent Moisture (IM) is water contained in coal when coal is formed. IM is specifically found in the internal pore structure of coal and has a vapor pressure lower than normal vapor pressure. IM levels are considered as the basic characteristics of coal. High IM levels correlate with calorific value. The higher IM levels, the lower the caloric value. Calorific value is one of the main parameters in determining the quality of coal. The higher the calorific value, the higher the heat produced by coal. The purpose of this observation is to determine the relationship of Levels of Inherent Moisture (IM) to the calorific value of coa l Keywords : Coal, Correlation, Inherent Moisture, Linear Regression.

Abstract

PERTAMINA (Persero) RU III Plaju-Sungai Gerong is a processing unit owned by PT. PERTAMINA. One of the units found at PT. PERTAMINA RU III Plaju, a unit of Residue Fluid Catalytic Cracking Unit (RFCCU), which is located in the Crude Distiller and Light Ends (CD & L) section, which is part of the processing and production of petroleum. Reliability of operation on the Reactor and Regenerator at the RFCCU is one of the determining factors for further processes in the next unit. This study aims to determine the operating conditions of Reactors and Regenerators that are good in order to achieve the desired product and know about the problems found in the Reactor and Regenerator. Based on reactor temperature specification data, which is 515-590ᵒC and the reactor pressure specifications are 1.5-1.69 kg/cm2, while the regenerator temperature specifications are 676-770ᵒC and the regenerator pressure specifications are 1.4-190 kg/cm2. The temperature and pressure on the reactor and regenerator, 11-25 July 2018 are still within the internal limits of the catalytic cracking process. The average reactor temperature is 506.7ᵒC and the reactor pressure is 1.47 kg/cm2, while the temperature of the regenerator is 677ᵒC and the regenerator pressure is 1.31 kg/cm2. In this study, to get a good operating condition of the reactor and regenerator, it must be considered in the addition and withdrawal of the catalyst continuously in order to maintain the activeness of the catalyst to the feed. Keywords: Catalyst Silica Alumina; Catalytic cracking; Reactor and Regenerator.
