Abstract

Employees are a supporting factor in a company or agency, because with employeeswho have company qualification standards, the company's productivity will be maintained and will increase. The AHP and SAW methods can be used to determine the best employees. There are 3 criteria and 16 alternatives that are given a value based on the scale of importance and weight for each criterion that has been determined by the Samarinda City Samsat Main Office which will be processed to find a sensitivity value using two methods, namely AHP and SAW. By carrying out the calculation process as much as 6 times the weight addition experiment where each weight is added to the value of 0.5 and 1 which is applied to the two AHP and SAW methods produces the sensitivity values of the two methods and uses two experiments with the first formula (XA – XB) and ( XA + XB ) then the sensitivity value obtained from the first trial of the AHP method is - 2.592705356 and the sensitivity value of the SAW method is -4.522690058. The second experiment added the value (XA + XB) so that the results of the sensitivity values of the two methods were obtained, namely AHP 5.952672848 and SAW method 8.358567251. From the calculations of these two methods, the SAW method was chosen which is more sensitive, so the best employee with the highes score at the Samsat Main Office, Samarinda City, was A1, namely the Selvi Salamah alternative, with a priority value of0.944444444.

Abstract

Essay is one of the test questions to measure students' understanding of learning. Respondents can organize the answers to each question in their own language style, so it takes time to make corrections. It takes a system that can assess essay answers automatically quickly and accurately. Auto Essay Scoring (AES) is a tool that can assign grades or scores to answers in the form of essays automatically. In giving grades automatically, AES requires machine learning with training data that contains answer data that has been given a value by the assessor. In this study, AES was used to assess the Indonesian language midterm exams using the Bag of Word extraction feature and using Support Vector Regression. The Root Mean Square Error value obtained when evaluating AES is 1.99.

Abstract

The purpose of this research is to analyze the risk of accidents in the construction project of drainage in Semani (Sentosa-Remaja-A. Yani) with the aim of assessing the level of accident risk that occurs. Occupational Safety and Health is an obligation mandated by the Labor Law and the Minister of Manpower Regulation, so that the risk of accidents can be minimized. In the implementation of the drainage project in Semani (Sentosa-Remaja-A. Yani), the Occupational Safety and Health System (K3) has been applied properly, but accidents often result from the negligence of the workers themselves. Therefore, an appropriate approach is needed to identify accident risks. Hazard and Operability Study (HAZOP) is a method that can be applied to identify and analyze the risks of work accidents. The research results show that high-risk conditions account for 32%, medium-risk for 54%, and low-risk for 14%, so improvement recommendations are more focused on high and medium-risk conditions

Abstract

Concrete, known for its high compressive strength and resistance to environmental degradation, proves ideal for durable building construction if implemented correctly. Mix designers, implementers, and supervisors must comprehend concrete properties to prevent errors in construction. Vibrators play a crucial role in enhancing concrete quality and strength during casting, facilitating air removal, ensuring even distribution, and increasing density. This research evaluates the impact of vibrators on mechanical properties and strength, utilizing a hammer test to compare unconfined compressive strength in samples cast with and without vibrators. Results indicate that vibrators significantly enhance concrete compactness, reduce cracking risk, and improve pressure resistance. Additionally, they positively influence aggregate distribution and reduce porosity. Integrating vibrators into the casting process is essential, offering tangible benefits for structural performance and building durability. Practical implications include guidance on optimal vibrator use in construction projects for superior outcomes. Concrete damage poses a common challenge in construction, affecting elements like columns, beams, plates, and walls. Conducting case studies on damage causes is crucial to identify and minimize potential issues, ensuring the long-term integrity of structures.

Abstract

This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on the response to local inundation of seawater. This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on response to local inundation of seawater which includes Stability, Flow, VIM, VMA, and VFB. In the 4-day seawater puddle model cycle, 12 specimens were made: 3 fly ash fillers, 3 glass powder waste fillers, and 3 normal asphalt, tested for 5 hours and 10 hours. This study explores the impact of fillers and inundation cycles on asphalt concrete characteristics. To realize the model of seawater puddles, in cylindrical specimens PVC retaining rings of the same diameter as the specimen (100 mm) are used tightly covered with silicone on the specimen surface. Filler with glass powder has low hygroscopic properties, which can help reduce moisture absorption in asphalt mixture beyond filler with fly ash. This can reduce the risk of changes in mechanical properties due to high water content. This study can provide an analysis of how well the asphalt mixture is able to withstand moisture and the extent to which glass powder filler and fly ash filler affect the absorbency of the mixture.
