Abstract

Abstract In the machining process, there are three parameters that need to be determined before the machining process is carried out, namely: depth of cut (a), feed motion (f) and cutting speed (v). Determination of the three parameters of the machining process will determine the quality of the product to match the desired geometry and tolerance. The three parameters of the machining process will affect tool life, where the selection of a constant depth of cut and feed motion will produce the most optimum level of tool wear. This study used several machining parameters with several variations, namely: depth of cut (a) of 0.5 mm; 0.8mm; 1.1mm; and 1.4 mm and feeding motion (f) of 0.062 mm/revolution and 0.1 mm/revolution. The machining process is carried out at a constant (n) rotation of 425 rpm. Based on the research that has been done, it was found that the tool life on the feed motion (f) = 0.062 mm/revolution is better than that on the feed motion (f) = 0.1 mm/revolution, where at (f) = 0.1 mm/revolution chisel wears out faster. Optimum cutting conditions are produced at feed motion (f) = 0.062 mm/revolution and with a depth of cut (a) = 1.1 mm where the production cost (Cp) is Rp.746.56/product.

Abstract

This study aims to get an overview of the operational parameters of a small-scale electrical generation plant that utilizes thermal energy included in the flue gases of garbage waste incineration. The organic Rankine cycle (ORC) thermodynamic system was performed to evaluate this system. The organic fluid was used as a heat transfer medium instead of water because it has a low boiling point so it does not require a lot of thermal energy to generate small-scale electric power. Hexane was used as the working fluid and Aspen Hysys was used as a tool to perform simulations. The plant is optimized through the operating temperature, working fluid flow rate, and pressure to obtain electrical output power that can be obtained. The simulation results show that flue gas at a temperature range of 300 to 350 0C can produce electric power in the ranges of 7.84 to 128.6 kW at a working pressure ranges of 2.5 to 7.5 bar, and working fluid flow rate of 3.600 to 10.100 kg/h

Abstract

The development of urban planning and infrastructure such as roads, buildings, bridges, ports has increased in recent years in Pontianak City. One of them is the construction of Jalan Parallel Sepakat II which was carried out in early 2022, connecting Jalan Sepakat II to the Tanjungpura University Campus Complex. In the case in the field, the previously compacted embankment has decreased, so backfilling is carried out to adjust the planned elevation. Due to the unsafe existing condition factor, improvements were made that were supported by retaining wall modeling. In addition to the retaining wall modeling, the current planning in the field is also stabilized by using a pile and geotextile, in order to increase the bearing capacity of the soil and can minimize the decrease or deformation that occurs at the research location. In the process of analyzing the retaining wall, analysis is also carried out with the Plaxis Proffesional 8.6 program. The results obtained in the form of deformation numbers and safety factor results. From the conclusion, the factor of safety is obtained which is not safe so that it is feasible to be reinforced. However, some adjustments are needed to the design plan so that it can function properly in accordance with the intent and purpose of the reinforcement.

Abstract

The usage of geosynthetics to improve the bearing capacity on granular material of embankment construction is worldwide familiar applied. The paper elaborates the lateral displacement of embankment inserted geosynthetics resulted vertical load on the top of embankment. This type of construction is applied like Mechanically Stabilized Earth- Retaining Wall (MSE-RW). Varied distances of inserted geosynthetics with low tensile strength on granular material of embankment for 20, 30, 40, 60 respectively cm installed on totally 140 cm-high of embankment. Each of layer is installed with varied distances with 120 cm -wide must be wrapped in order to avoid loses grains of granular material of embankment. The varied vertical surcharge at the above of embankment started with 19, 34, 49 kg respectively. The result of research indicates that number layer with inserted geosynthetics on granular material of embankment influences the lateral deflections which much more layers of geosynthetics or smaller vertical distance of geosynthetics provides smaller lateral deflection. Beside that increased vertical load implies the lateral deflection is increased.

Abstract

The number of vehicle usage, especially motorcycles, in Indonesia has significantly increased in the past 10 years, particularly among young people. This has had an impact on the declining air quality in public places, including on campus grounds. PM2.5, as one of the hazardous pollutants to health, needs to be given special attention regarding its dispersion concentration in areas heavily frequented by the public, such as parking lots on campus. This study analyzes the level of PM2.5 concentration in the campus parking lots at Universitas Lampung, with the aim of observing the pattern of PM2.5 pollution in the campus area, considering the increasing number of motorcycles entering the campus every year. The measurement of PM2.5 levels was conducted using a light scattering sensor in two parking lots with different microenvironments, and then its correlation with motorcycle activities at each location was analyzed using simple regression. Based on statistical analysis, it was found that the differences in microenvironments affect PM2.5 levels significantly. The number of motorcycle activities also has a positive correlation with the level of PM2.5, where the average PM2.5 concentration recorded has exceeded the threshold set by the government, which is 15 µg/m3 per day. However, the effect of the microenvironment in this study is stronger than the number of vehicles. Therefore, in the future, appropriate policies and strategies are needed to reduce PM2.5 concentrations in public areas, especially on campuses, to prevent the associated risks of the pollution.

Abstract

The importance of accurate, real-time intelligence in modern warfare is crucial, especially in reconnaissance and surveillance operations. Currently, drones are widely used for reconnaissance, but generally rely only on the operator's ability to monitor operation targets. This research is aimed at developing an AI vision assistance system to enhance the ability to detect military vehicles and infantry. The method used is computer vision trained to recognize and differentiate several military objects. The YOLO model is used to detect and distinguish objects. To improve detection capabilities, the YOLO v8 model was retrained with an additional dataset sourced from battle recordings on the battlefield. The results show a detection accuracy rate of 95% in detecting vehicles and infantry under normal visual conditions. The model from this research can be used to enhance the capabilities of reconnaissance drones and the effectiveness of monitoring operations.
