Assessing possible risks in construction projects helps predict risks and plan risk management strategies. In construction projects, many factors can affect project completion, including the risk of work accidents. This research aims to look for Occupational Health and Safety risk factors for COVID-19 in construction projects by conducting a literature study on several previous studies. The research methodology is a literature search using the Publish or Perish application. Relevant literature is then used as a source of research. Based on the results of a literature study, twenty-eight risk factors are considered to have the potential to occur in construction projects consisting of eighteen OHS risk factors and ten COVID-19 risk factors. The five most common risk factors for OHS in previous studies were: falling from a height, being hit by material, being electrocuted, being scratched by workers, being punctured by material, and being hit by heavy equipment.

The predator-prey model is the mathematical model that describes the interaction behavior between prey and predator. This research discusses the modified Leslie-Gower model by considering the cannibalism behaviors of the prey that contains Holling type I response function, which is a predator with passive characteristics. The stability analysis stage includes determining the system's solution in the form of an equilibrium point, analyzing the local stability of each equilibrium using eigenvalues, and numerical simulation to synchronize the analysis results. Numerical simulations visualized in phase portraits with Python software. The results of the local stability analysis of the system obtained four equilibrium points, namely, equilibrium points are unstable while is asymptotically stable with certain conditions. The results of numerical simulations show that only the equilibrium point which is asymptotically stable when the environment carries capacity parameters (e=2.1). Meanwhile, when e=2.878 then, only is asymptotically stable. In this research also using two different initial values, it is concluded that whatever the initial value used, the system solution always converges to the equilibrium points dan . Changes in environmental carrying capacity affect the dynamics of system solutions.
捕食者-猎物模型是描述猎物和捕食者之间相互作用行为的数学模型。本研究通过考虑含有霍林 I 型响应函数的猎物（即具有被动特征的捕食者）的食人行为，讨论了修正的莱斯利-高尔模型。稳定性分析阶段包括以平衡点的形式确定系统的解，利用特征值分析每个平衡点的局部稳定性，以及同步分析结果的数值模拟。数值模拟通过 Python 软件实现相位肖像可视化。系统局部稳定性分析结果得到了四个平衡点，即平衡点不稳定，而在一定条件下渐近稳定。数值模拟结果表明，只有当环境携带容量参数（e=2.1）时，平衡点是渐近稳定的。同时，当 e=2.878 时，只有平衡点是渐近稳定的。本研究还使用了两种不同的初始值，得出的结论是，无论使用哪种初始值，系统解总收敛于平衡点 dan。环境承载能力的变化会影响系统解的动态变化。

The prey-predator model in this article reviews the interaction of two populations with a type III Holling -type III functional response and anti-predator behavior. The dynamic analysis starts by determining the basic model construction assumptions, equilibrium and stability points, and numerical simulations using Python. Dynamic analysis results obtained four equilibrium points with types of stability, namely. which is unstable, which is asymptotically stable , and . Which is stable under certain conditions. The numerical simulation results show double stability at the equilibrium points. and with the anti-predator behavior parameter value . The anti-predator parameter value indicates a change in stability that is only the equilibrium point. Differences in the values of the anti-predator behavior parameters affect changes in system solutions and impact reducing predator populations.

One of the supporting components in running a company is the quality of service delivered to customers. &T Express Benjeng was among the first freight forwarding firms to establish itself in Gresik Regency's Benjeng sub-district. Several trip merchants were identified in Benjeng Gresik District throughout time. As a consequence, the number of people using J&T Express Benjeng services is falling. J&T Express Benjeng had never studied customer satisfaction before doing this research; therefore, evaluating the quality of customer service was critical to remain in an increasingly competitive business environment. The Service Quality techniques, Importance Performance Analysis, and the Customer Satisfaction Index were used in this research. The biggest disparity, according to the results of this study, is in the reliability dimension, the assurance dimension, the responsiveness dimension, the empathy dimension, and the tangibles dimension . According to the Importance Performance research, nine question indicators in quadrant I must be emphasized if performance is to increase. The Expedition must increase the value of the Customer Satisfaction Index by prioritizing repairs in quadrant I of the IPA Kartesius diagram. The Customer Satisfaction Index result indicating that the customer is pleased.

Lathe machines are used to work on cylindrical objects. Tool wear is often a problem in the turning process and impacts the results of the machining process. The research aims to compare lathe insert tool wear levels TNMG160404-MA and TNMG160404-TF. The research used the experimental method directly using a lathe with variable machining on feeding (f) 0.04 mm/rev and 0.08 mm/rev, spindle (n) 540 rpm, and depth of cut (a) 4 mm. Tool wear was measured using an optical microscope by measuring the maximum edge wear on the tool (VBmax) and to determine the significance of tool wear using statistical analysis. The results showed wear level insert tool of TNMG160404-MA at a feeding of 0.04 mm/put an average of VBmax = 85.00(μm) and a feeding of 0.08 mm/put VBmax = 63.23(μm). TNMG160404-TF insert tool wear at 0.04 mm/put feed VBmax = 76.18(μm) and 0.08 mm/put feed VBmax = 58.43(μm). On a feeding, 0.08 mm/put motion, the standard deviation (s) of the TNMG160404-MA insert tool is 16.2, and the standard deviation (s) of the TNMG160404-TF insert tool is 17.8. On a feeding of 0.08 mm/rev, the results of t-count = 0.630 and t-table = 2.101, so t-count < t-table (0.630 < 2.101), the statistical analysis results using the t-test showed no significant difference in the level of wear of the two types insert tools.

The results showed wear level insert tool of TNMG160404-MA at a feeding of 0.04 mm/put an average of VBmax = 85.00(μm) and a feeding of 0.08 mm/put VBmax = 63.23(μm). TNMG160404-TF insert tool wear at 0.04 mm/put feed VBmax = 76.18(μm) and 0.08 mm/put feed VBmax = 58.43(μm). On a feeding, 0.08 mm/put motion, the standard deviation (s) of the TNMG160404-MA insert tool is 16.2, and the standard deviation (s) of the TNMG160404-TF insert tool is 17.8. On a feeding of 0.08 mm/rev, the results of t-count = 0.630 and t-table = 2.101, so t-count < t-table (0.630 < 2.101), the statistical analysis results using the t-test showed no significant difference in the level of wear of the two types insert tools.","PeriodicalId":339766,"journal":{"name":"Jurnal Sains dan Teknologi Industri","volume":"134 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
