Abstract

One of the alternative energy source that can be developed is the Wind Power Plant. The need for electrical energy that continues to increase, it takes not a little time to build a power plant. System planners must also be able to see the possibilities of the development of the power system in the years to come. Indonesia is a country that has abundant energy resources, one of which is a source of wind energy. Indonesia which is an archipelagic country and one of the countries located on the equator is a factor, that Indonesia has abundant wind energy potential. In this study the output that produced is a renewable energy product, which is a power plant product in the coastal area. In the previous study a low-speed permanent magnet generator has been produced which can be driven by wind turbines which will be continued through the design of vertical type wind turbines. The results of this study can then be developed, especially for electricity generation products in the coastal region. In the process of planning and manufacturing vertical type wind turbines, to produce enough power to meet household electricity needs should be based on several factors that support the effectiveness of the power produced by the turbine, namely: Turbine Dimensions (Length and Blade Width), Material Strength , Shaft, Bearing and Generator Shaft

Abstract

The study of performance is incredibly fascinating. One of them is the way in which mid-level management functions as both a conduit for information to top management and the person in control of subordinates. This study aims to enhance the coordinator of the industrial department's performance. This study's data processing and analysis procedure employs a qualitative approach by carrying out an analysis using the TNA (Training Need Analysis) method. At electromotor engine repair service firms in East Java, this method is used to assess the variables that contribute to delays in the completion of repairs of goods as well as the kind of training provided to coordinators to prevent delays in the completion of repairs of goods. The outcomes show in the study, it was discovered that the absence of effective communication between division coordinators in the industrial department, skill gaps, and workers who are not suited for the job are the main causes of delays in the completion of goods. Because the percentage is still low for corporate performance and still less productive, the performance value in each division, such as industrial repair, is 6.1%, vacuum pump 6.6%, blower 6.2%, fabrication 7.4 and rewinding 7.5% to complete the items.

Abstract

In an era where digital transformation dictates the survival of technology firms, selecting the optimal branch location is no longer a peripheral decision it is a strategic imperative. This study offers a powerful yet practical application of the Analytic Hierarchy Process (AHP) to evaluate potential expansion sites for a mid-sized software development company in Indonesia. By integrating expert judgments with location-specific criteria such as talent availability, infrastructure reliability, ecosystem proximity, and cost efficiency, the AHP model provides a structured, transparent, and replicable framework for decision-making. The results clearly identify Location A—an urban tech hub near major IT universities as the most strategic choice, significantly outperforming other alternatives. More than just a location ranking, this model demonstrates how conventional decision-making in software enterprise expansion can be elevated through applied analytical thinking. The study also proves that even without high-end analytics platforms, decision models built in common tools like Excel can yield robust and scalable insights. These findings carry immediate relevance for technology firms, policy planners, and academic researchers who seek to align operational expansion with long-term innovation and productivity outcomes in knowledge-based industries.

Abstract

Determining delivery routes thatminimize total cost is a key issue in goodsdistribution. This study focuses on a bottleddrinking water (AMDK) company in City X thatdistributes its products to multiple retail outlets withdifferent service time requirements. Such conditionsfall within the scope of the Vehicle Routing Problemwith Time Windows (VRPTW). In this study, a softtime windows approach is adopted, allowing vehiclesto serve retailers beyond their specified time limitsat the expense of penalty costs. The main objective isto identify optimal delivery routes under the softtime windows policy while minimizing total cost. Theresults demonstrate that the Hybrid GeneticAlgorithm outperforms the initial solution in termsof total cost reduction. The initial routes aregenerated using the Nearest Insertion Heuristic andsubsequently refined through mutation processeswithin the genetic algorithm framework.
