Abstract

This study aims to analyze the traffic performance on arterial roads in Makassar City in the present and future with the implementation of Electronic Road Pricing, as well as analyze how many tariffs can be applied when Electronic Road Pricing (ERP) is used. The data were collected from traffic surveys and questionnaires distributed to users of four-wheeled and two-wheeled vehicles. From the data, the existing traffic conditions on the road were analyzed, and the probability of moving road users was calculated during the implementation of ERP. Furthermore, the Willingness To Pay method determines the rates that can be applied. The results of the research show that when ERP is implemented on the Andi Pangeran Pettarani Road, there will be a 40% reduction in traffic flow due to the route changes and a 42% reduction in traffic flow due to the modal shifts. This affects improving traffic performance in the future, where the existing condition of this road segment which was initially at LoS D and E, can be increased to LoS B and C. The tariff that can be applied to the ERP system is Rp 8,838 for four-wheeled vehicles or more and Rp 4,343 for two-wheeled vehicles

Abstract

At least 617 cases of fire disasters were recorded in Balikpapan City from 2010 to 2020. In response, fire disaster mitigation is still a problem, especially in dense residential areas and unclean environments. One of the sub-districts with the characteristics of dense settlements and a history of fire incidents is Karang Rejo Village. This condition can be an obstacle in disaster mitigation. Therefore, it is necessary to identify appropriate mitigation efforts for this sub-district. Vulnerability assessment can be an essential first step to reducing the impact and losses of a fire disaster. The purpose of this study is to formulate fire disaster mitigation based on the level of vulnerability in Karang Rejo Village, Central Balikpapan District, using the spatial multi-criteria analysis method. The research results obtained are structural fire disaster mitigation at low, medium, and high vulnerability by mitigating aspects of building density, percentage of built-up areas, building materials, the width of access roads, availability of water reservoirs, availability of vacant land, the portion of households working in the informal sector, and the ratio of poor people.

Abstract

The welding process is a permanent connection process for metal materials using heat energy. The GTAW (Gas Tungsten Arc Welding) welding method is carried out on AISI 1045 steel material with a solid round shape, which has the characteristics and properties of the material slightly above low carbon steel. The welding process was carried out based on AWS A5.18 standard specifications, in this study. by varying the welding amperage between 70, 90, and 110 amperes as well as the ER70S-G series electrodes.To check the results of the welding with the amperage variation, perform tensile testing with standard ASTM A-370 testing, hardness testing using the Vickers method with standard ASTM E-92 testing, microstructure inspection, and grain size calculations as a control for the results of the hardness test. The focus of testing and inspection is carried out in three influential areas, namely, areas of weld metal, HAZ (heat-affected zone), and base metal.The results of this study show that for 70 A welding amperage, the tensile test results in all samples breaking in the weld metal area. While welding amperage 90A broke two samples in the weld metal area, welding amperage 110A broke one sample in the weld metal area. For the results of the hardness test at 110 A amperes, the hardness ratio in the weld metal area to the HAZ area shows that the difference in hardness is not too large compared to the two amperes used, so a welding amperage of 110 A can be recommended. While the results of the microstructure examination in the weld metal area were dominated by pearliet and martensite with a little bainite, the hardness results in the weld metal area were harder compared to the HAZ area and base metal. Likewise, the results of grain size calculations using the Heyn method for regions with higher hardness make the grain sizes appear denser and smaller.

Abstract

Data science is becoming familiar to the public and companies in the era of the Industrial Revolution 4.0. One part of data science is data mining. Data mining is the process of collecting information to see patterns from very large datasets and data discovery which is processed in such a way as to become knowledge based on the interpretation of the information obtained. This paper aims to compare the performance evaluation results of several classification algorithms in data mining (such as DT C-45, Neural Network, KNN, LDA, Naïve Bayes, SVM, and Rule Induction) for identifying types of glass based on its elements and the refractive index. The dataset used is a glass identification dataset from the UCI Machine Learning Repository. The results of the evaluation can be seen from the criteria like Accuracy and Kappa using 10-fold-cross validation. As a result, the K-Nearest Neighbors (KNN) algorithm has the best Accuracy and Kappa values, namely 72.90% for Accuracy and 0.632 for Kappa values. To determine the significance of the accuracy value, the T-Test method is used.

Abstract

Soil is one of the most important elements in any civil engineering work, almost all construction activities are related to soil. One of the most common soil problems is expansive soil. This type of soil has a high potential to expand when compared to other types of soil. This research aims to find out how expansive the tested soil is and how it reacts when wetting. The test in this research is experimental, where the expansive soil test is modeled in a rectangular test box with a soil volume of 0.08 m3. The swelling and expansion pressures were measured using proving rings and dials, each totaling five units. The expansive soil used came from Sambungmacan Subdistrict, Sragen Regency, Central Java. The results of the property index test of Sambungmacan soil have a plasticity index percent value of 49.33% and a liquid limit (LL) of 90.16%. The test results showed that the maximum swelling reached 28.3% of the initial soil height of 200 mm and the maximum soil swelling pressure reached 103.23 kPa with a moisture content of 22.62%. The maximum pressure that occurs in each proving ring is at an average moisture content of 31.81%. The results of this study also show the effect of every 1% moisture content will produce a percent soil swelling of 0.40% to 1.08% and the average percentage of swelling pressure that occurs is in the range of 4.65 kPa to 10.26 kPa at every 1% swelling.

Abstract

The research site is one of the high-risk flood district zones along with Panca Lautang, Tellu Limpoe, and Wattang Sidenreng District since it is adjacent to Sidenreng Lake. The issue allied to climate change at the research site is a real phenomenon in which high rainfall occurs, leading the lake water to overflow and the weather, which previously could be calculated by the community in various ways, is currently unpredictable. The clime vulnerability analysis was utilized at the outset of this study to figure out the level of climate vulnerability. Secondly, Spatial Analysis using ArcGIS Software with Overlay Method towards each flood parameter to address the level of high-risk flood at the site of the research. The third analysis used in this research was AHP-SWOT to formulate some alternative strategies to overcome flood disasters brought about by climate change in the area of Lake Sidenreng. The results of the study showed that the level of flood vulnerability was Very Vulnerable, with 130.94 km2, Vulnerable at 134.98 km2, Quite Vulnerable at 88.93 km2, Less Vulnerable at 22.97 km2, and Not Vulnerable at 3.03 km2 with the total amount of 380.85 km2. Subsequently, the analysis results of the climate vulnerability from 27 villages, 14 of which are at a very low level (Class I), 2 villages are at a low level (Class II), 4 villages are at a Medium level (Class III), and 1 village which is Wette Village is at a very high level (Class IV). According to alternative strategy on AHP-SWOT Analysis, it was found that the space matrix is at Quadrant III of the W-O Strategy namely 1) the development of human resources and public role to nourish environmental hygiene and increase the capacity of vulnerable groups by empowering society with several trainings to improve human resources and group capacity and promoting awareness among people who lived in those vulnerable areas to maintain environmental conditions, the formation of climate villages and the formation and development of disaster care communities to minimize the impact of flood disasters that occurred as a result of climate change; 2)  Management of climate change risk by local government and stakeholders either structurally or physically (engineering the built environment, technological choices and environment-based services or institutional-based services (choices in law and regulation, economics, policies and programs of government) by involving potential experts; 3) development of flood susceptibility maps and climate change vulnerability risks that are integrated with disaster mitigation maps so that people figure out the areas which have a large impact on climate change disasters
