Abstract

Water sources such as rivers, lakes, and reservoirs often have quality issues, making them unsuitable for daily human use. Despite ongoing government and societal efforts to control waste and reduce pollution, water treatment remains critical to ensure its suitability for consumption. Effective water resource management requires specialized skills, including design, technical implementation, operational capabilities, and maintenance. Post-construction, water treatment projects frequently face issues such as substandard operations and inadequate maintenance. This study explores methods to enhance river water quality through improved operational management and maintenance. Key improvements involve regular equipment inspections, planned operations, and diligent maintenance control. Findings indicate that equipment performance is within acceptable ranges, with average motor vibration at 0.25, engine temperature at 49.3°C, and engine speed at 1230 rpm. Water quality after treatment shows a pH of 7.71 NTU, demonstrating that operational and maintenance standards are being met effectively.

Abstract

Failure due to material fatigue can be potentially fatal as it may lead to fractures without any initial detectable deformation. Factors such as high maximum load and large stress cycles accelerate the material fatigue process. In the design of a lower limb exoskeleton robot, the strength and safety of the robot are primary focuses, particularly in the Link Joint mechanism. The comfort and safety of the structure are determined by the geometry and type of material used. Analysis using Fracture Mechanics is employed to evaluate cracks in the Link Joint mechanical structure, with the calculation of the Stress Intensity Factor (SIF) value as an indicator of the stress intensity on the crack due to load. This research aims to identify critical stress and estimate the service life of the mechanism through testing using Finite Element Method-based software, specifically Solidworks 2020.

Abstract

This research aims to analyze the bending strength of composite materials based on corn fiber and fiberglass with Lycal resin, which are produced using two methods, namely vacuum bagging and vacuum infusion.Composite materials are increasingly being used in various industries because of their light and strong haracteristics. In this research, corn fiber was chosen as a natural reinforcement material because of its abundant availability and economic potential, while fiberglass was used as additional reinforcement to increase the strength of the material.The composite manufacturing process is carried out using two different methods, namely vacuum bagging and vacuum infusion, which are then tested using the ASTM-D 790 standard to determine the mechanical characteristics of the material, especially in terms of its ability to withstand bending loads. Apart from the bending test, material density calculations were also carried out to compare the weight and density of the two manufacturing methods.The test results show that the vacuum infusion method producescomposites with higher flexural strength than vacuum bagging. This is caused by a more even distribution of resin and minimal air trapped in the material structure during the vacuum infusion process. The composite produced from this method also has a lower density, making it lighter but still mechanically strong.It is hoped that this research can contribute to the development of natural fiber-based composite materials that are environmentally friendly and efficient, and have the potential to be applied to the aerospace industry, especially in the manufacture of UAV structures

Abstract

The use of motorized vehicles currently experiences a very significant increase, this has an impact on increasing air pollution due to exhaust gas emissions from combustion. One of step to minimize the level of air pollution due to exhaust emissions is to choose the right fuel, so that the combustion in the combustion chamber is perfect. Based on this, a problem was formulated related to the influence of fuel’s type on exhaust gas emission values in vehicles with injection otto engine system technology. The research object is the 2017 Toyota Sienta 1.5 G M/T car using electronic fuel injection. The types of fuel used in this research are Pertalite, Pertamax, and Pertamax Turbo. The Test results from the use of Pertalite, Pertamax and Pertamax Turbo fuel types show that the exhaust gas emission values for CO, HC and CO2 content will decrease when the engine speed is higher. The best type of fuel from the test results is Pertamax Turbo RON 98, because almost all test results for CO, HC and CO2 content at various types of engine speed show the lowest results. In accordance with the Minister of Environment Regulation No.06 of 2006 concerning Exhaust Gas Emission Thresholds for Old Motor Vehicles, the vehicle tested was declared to have passed the exhaust emission test. Minister of Environment Regulation, 2006 determines the maximum threshold values for CO = 1.5% and HC = 200 ppm.

Abstract

In the turning process, the surface finish of a workpiece can influence the level of visual quality of a workpiece. CNC machine cutting parameters include feed speed, feed depth, and cutting speed. The aim of this research is to determine the effect of carbide insert tool types ZCC WNMG 060408 – DM and VBMT 160408 – HM on the average roughness value in the turning process with a rotational speed of 500 rpm and feed speed variations of 0.10 mm/rev, 0.15 mm/ rev and 0.20 mm/rev on S45C steel material. This research is located at PT. Bin Smeer Jaya with the research sample, namely S45C steel material. This research will be carried out with 3 samples of surface roughness testing each with varying feeding, where the turning process will be carried out on a CNC lathe machine first using ZCC WNMG 060408 – DM and VBMT 160408 – HM carbide insert chisels. The desired roughness standard is 1.8 µm – 2.2 µm. Based on the results of testing the surface roughness value of S45C steel material, the data obtained using the Handysurf E-35 surface roughness measurement tool, the roughness value using the ZCC WNMG 060408 – DM specimen 3 feeding 0.20 mm/rev carbide insert chisel was 2.38 µm, whereas for specimen 3 feeding 0.10 mm/rev is 4.11 µm. Then for the VBMT 160408 – HM carbide insert chisel, specimen 1 feeding 0.10 mm/rev is 1.48 µm, while for specimen 2 feeding 0.20 mm/rev it is 4.41 µm. So it can be concluded that the lowest roughness value occurs in the VBMT 160408 – HM carbide insert chisel compared to the ZCC WNMG 060408 – DM carbide insert chisel type. Therefore, the best level of surface roughness results occurs in the VBMT 160408 – HM carbide insert with the desired roughness standard and optimal visual quality

Abstract

This research aims to analyze the performance of the pump P-8340A operated by an electric motor and a diesel motor in the tank T-8320A/B. Apart from focusing on the performance of the two types of motors as pump drivers, this study also evaluates the time to fill the fire fightine water tank and the factors that influence the operational efficiency of the pump.The research methods used include taking field data at the operating location, analyzing flow capacity, pressure head and speed head, as well as calculating pump power and efficiency. The analysis results show that pumps with electric motors have a longer charging time compared to diesel motors, namely 38 hours for electric motors and 29 hours for diesel motors, with flow capacities of 239.68 m³/h and 310.54 m³/h respectively.From this research it was also identified that the total head losses in the pump were influenced by friction factors in the piping system and the characteristics of the fluid being transferred. The conclusion of this research is that although electric motors are more efficient in energy consumption, diesel motors are still superior in capacity and speed in operating the P-8340A pump. Recommendations for future operations include closer monitoring of the piping system and considering modifications to the drive system according to operational needs.

Abstract

Effluent Treatment Plant (ETP) is an environmentally based regional waste treatment system that aims to treat liquid waste so that it can produce waste that meets quality standards. Liquid waste that cannot be treated properly can result in environmental pollution. The research methodology used is a method of observation study by direct observation including the processing process in the ETP plant, the data collected is calculated based on the parameters of liquid waste before and after processing. From the data, there are several days that show that only 80% of waste can be treated on ETP from the total waste sent from the production plant. This has an impact on the quality of TSS (Total Suspended Solid) parameters treated at CAF experiencing outspec of 20.79% of the operational standards of TSS parameters in PT X. Based on the results of research found that CAF (Cavitation Air Flotation) capacity is less maximal when the flowrate of waste to be treated is high so that the treatment capacity in ETP cannot keep up with the amount of waste sent from the production plant. This can cause the level in the accident pond and equalization pond high and eventually result in wastewater overflowing into the environment so from this analysis process is obtained the proposed improvement of the process to improve the performance of IPAL is to add CAF to the pre-treatment process.

Abstract

Efficiency and cost are important points in the development of the renewable energy industry, especially solar cells. While the first generation of crystalline silicon-based solar cells had the biggest constraint in cost, the second generation of thin-film solar cells is trying to offer innovations with relatively lower cost but high flexibility compared to the first generation. This article explores the essential developments in the invention of second-generation thin-film solar cells, including materials, performance, and technology. Through their respective fabrication processes, ultra-thin-film solar cells based on various materials such as amorphous silicon, Cadmium Telluride/Cadmium Sulfide (CdTe/CdS), and Copper Indium Gallium Selenide/Copper Zinc Tin Sulfide (CIGS/CZTS) were discovered. With these types of thin-film cells as well, the use of solar cells is more flexible for various applications mainly due to their lighter weight. Although the efficiency of their photovoltaic effect or light-to-electricity conversion is generally lower than that of crystalline silicon solar cells, these thin-film solar cells are efficient in absorbing light in dimmer conditions.
