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.","PeriodicalId":339766,"journal":{"name":"Jurnal Sains dan Teknologi Industri","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139354270","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}

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.

If inventory is not managed properly, it can result in high storage costs, the risk of inventory shortages, or even expired products. Therefore, it is important to have the right strategy in managing inventory. This study aims to classify inventory items owned by UD. XYZ in order to minimize inventory costs by focusing inventory procurement on high-value priority items. The method used in this study is Activity Based Costing analysis (ABC). The results of this study are based on the ABC classification there are 7 types of goods that fall into category A or priority are Aoka, Roma sandwich, My jelly, Slai olai, Trick, Choco pie, and Chiki balls. Where these 7 types of goods need special attention in terms of inventory management because they absorb the most investment funds from the total goods owned. By knowing these items, companies can focus on more precise inventory management, including in terms of procurement, storage, and inventory control. This can help UD. XYZ reduces unnecessary storage costs and ensures optimal availability of goods. The results of this study can contribute to the understanding of the application of the ABC method in the context of merchandise inventory management.

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).
