Abstract

Environmental problems caused by petroleum-derived plastic waste has become an important issue because it is difficult to degrade the environment. Therefore, attempts have been made to speed up the process of degradation of the polymer material is to replace synthetic polymers with natural poimer. Starch is a natural polymer that can be used for the production of material that is easily degraded, the raw material is abundant, but has a weakness in its mechanical properties. To improve the mechanical strength of starch, a reinforcing material in the form of inorganic material is usually added in a polymer matrix. In addition to improving shelf life in a plastic made from natural polymers required additional antimicrobial. Therefore, bioplastics prepared by mixing cassava starch as a matrix, glycerol as a plasticizer, ZnO as an amplifier, and clove oil as an antimicrobial. The optimum conditions to produce bioplastics with the highest tensile strength of 23.40 kgf /mm2 given by the addition of 0.8% of ZnO and 0.4 ml clove oil. While the highest percent elongation on the addition of ZnO 1% and 0.4 ml clove oil which is 346.00%. Based on the test results of water resistance and biodegradability, clove oil shown to inhibit the growth of microorganisms bioplastics and bioplastic IR spectra do not show any new functional group.

Abstract

This gas source that comes from the bowels of the earth contains many impurities and heavy hydrocarbons, both of which must be separated or even eliminated. To purify the treated gas to prevent damage to process equipment or pipe clogging. The removal process includes H2S removal, CO2 removal, oily water removal, mercury removal, and water content removal in natural gas. This study aims to determine the effect of flow rate and ambient temperature differences on the performance of the wellstream cooler and the level of efficiency of the heat transfer process in the wellstream cooler. Observations will be focused on the offshore platform wellstream cooler cooling system at PT. PHE NSO. Based on observational data, the results obtained using the Hysys method by entering the required data completely, Hysys will automatically perform calculations according to what is required and the calculation results will be plotted in graphical form. Heat transfer efficiency based on Hysys application calculations all show results of 99%. Thus it can be seen the effect of changes in flow rate and ambient temperature on the heat transfer process. The greater the flow rate, the greater the heat transfer that occurs and the higher the ambient temperature, the smaller the heat transfer occurs, so that the lower the ambient temperature, the more effective the heat transfer occurs.

Abstract

The circulation process is a process to make pipes in the LNG industry always in LNG operational cryogenic temperature condition -160° C. The LNG circulation line facility on the AAV inlet pipe is expected to flow LNG continuously as a solution to keep the pipe always in a state of cryogenic temperature. The pressure drop from one point to another with lower pressure is referred to as a "pressure drop. Loss of pressure in the process at the AAV piping system is caused by several parameters including pipe size, flow rate, and pressure also because of a change in pipe size and friction along the pipeline. The purpose of this research is to analyze the effect of pipe size on pressure drop and compare it with theoretical calculations and simulation programming. Hysys is engineering software designed to simulate processes in industry to design process calculations related to engineering. Based on the results of the manual calculation, the 3-inch pipe size has the lowest pressure drop value of 0.314 kg/cm2 and the results using aspen hysys is 0.053 kg/cm2. Using a double pipe piping system, the 4-inch annulus has a pressure drop value of 0.445 kg/cm2, and the result from Aspen Hysys is 0.059 kg/cm2. Pressure drop is significantly influenced by pipe size; the smaller the pressure drop that happens, the greater the pipe size must match the pipe connection size. The pressure drop that occurs in variations in pipe size has a great influence on the LNG flow back into the storage tank.

Abstract

This study aims to utilize Moringa leaves (Moringa oleifera) and Leucaena leucocephala leaves (Leucaena leucocephala) as raw materials for making environmentally friendly liquid organic fertilizer (POC). This study examines the effect of the composition of raw materials of Moringa leaves and Leucaena leucocephala leaves, as well as fermentation time on the quality of the resulting POC, which is tested based on parameters of pH, Total Dissolved Solids (TDS), macronutrient content (nitrogen, phosphorus, potassium), and C-organic content. This study was conducted with variations in the composition of Moringa leaves and Leucaena leaves at a ratio of 1:0, 3:1, 1:1, 1:3, and 0:1, as well as varying fermentation times for 7, 12, 17, 22, and 27 days. The results of the study showed that the combination of Moringa leaves and Leucaena leucaena leaves at a ratio of 1:1 and fermentation for 17 days produced POC with optimal nutritional content, namely Nitrogen (0.31%), Phosphorus (0.17%), Potassium (0.25%), and C-organic (0.42%). In addition, this study also showed that fermentation time had a significant effect on the quality of POC, with an increase in POC quality on the 17th day of fermentation. The results of this study can be used as an alternative in making liquid organic fertilizers with local, environmentally friendly raw materials, as well as contributing to sustainable agriculture through the use of more efficient and affordable fertilizers. Keywords: Liquid Organic Fertilizer, Moringa Leaves, Leucaena Leaves, Fermentation, Plant Nutrition.

Abstract

This study aims to optimize the blending formulation of Marine Fuel Oil Low Sulfur (MFO-LS) to comply with the International Maritime Organization (IMO) 2020 regulation, which limits sulfur content to a maximum of 0.50% m/m. The methodology involves optimization using the Generalized Refining Transportation Marketing Planning System (GRTMPS) software, followed by laboratory validation of four blending formulations. The evaluated parameters include kinematic viscosity, pour point, flash point, density, sulfur content, and other impurities based on ASTM and ISO 8217 standards. The results indicate that not all formulations met the required specifications. Blending 1 exhibited a high pour point issue, while Blending 2 failed to meet the minimum viscosity requirement. The optimal formulation was achieved in Blending 3, which utilized 40% short residue combined with distillate components such as kerosene, LVGO, and HVGO. This formulation successfully met all critical parameters, with a viscosity of 87 mm²/s, pour point of 24°C, flash point of 66°C, and sulfur content of 0.2% m/m. The findings also demonstrate that HVGO can be effectively utilized as a blending component within a 5–10% volume range without compromising product quality. Furthermore, the reformulation improves operational efficiency and economic value by maximizing the utilization of low-value residue streams. Therefore, the proposed blending strategy provides a practical and effective solution to meet global environmental regulations while enhancing the competitiveness of marine fuel products.

Abstract

Tube leakage in the air pre-heater system is a critical issue affecting the reliability and efficiency of coal-fired power plants. This study investigates the causes of tube leakage in the air pre-heater of a Circulating Fluidized Bed Combustion (CFBC) boiler Unit-2 at a 2×30 MW power plant of PT. XYZ. The analysis was conducted through dimensional and thickness measurements, visual inspection, and evaluation of operating conditions, including acid dew point calculation and air preheater performance. The results indicate that wall thinning occurs locally and non-uniformly, with minimum thickness reaching 0.00 mm at certain condition, indicating perforation. The inner diameter remains relatively constant, while the outer diameter and wall thickness decrease significantly, suggesting that degradation predominantly originates from the external surface. Visual observations reveal the presence of pitting corrosion, uniform corrosion, and deposit formation on both outer and inner surfaces of the tube. The calculated acid dew point of flue gas ranges from 128.98 to 129.73°C. At low load conditions, the temperature margin between flue gas outlet and acid dew point becomes very narrow, increasing the risk of acid dew point corrosion. In addition, reduced air preheater performance prior to maintenance contributes to the development of a corrosive environment. It is concluded that tube leakage is mainly caused by progressive external erosion-corrosion, with additional contribution from acid dew point corrosion under certain operating conditions. These findings highlight the importance of temperature control, air preheater performance optimization, and periodic thickness monitoring to prevent recurring failures.
