Abstract

The rapid advancement of technology demands that humans adapt to the evolving workplace. One of the impacts of technological development is the emergence of freelancers who use online platforms. Online platforms make it easier for freelancers and clients to collaborate. Currently, there are various Freelance Services Marketplace platforms available. However, it is important to note that the developers of these platforms are from outside Indonesia, which poses a risk to the security of people's data and the ease of payment applicable in Indonesia. With the high number of mobile device users in Indonesia,, the development of a mobile-based Freelance Services Marketplace application system that is tailored to local needs and takes into account the data security of Indonesian people, as well as involving local developers, is needed. This research aims to overcome these problems by designing a mobile-based freelance services marketplace application system using the Feature-Driven Development (FDD) method. The selection of FDD as an application development methodology is based on complex feature requirements, good planning management, emphasis on feature quality, and structured. The development process follows the FDD approach starting from feature planning and design, scheduling, implementation, and testing. The application design in this research is based on user needs with a focus on the features needed. This solution is important because it can be used by clients to find freelancers who match their needs and provide opportunities for freelancers to offer their services properly with guaranteed data security and transactions. The main result of this research is that the FDD method can help in the development of a freelance service marketplace application by paying attention to the systematic or structured level, quality, and security of the application.

Abstract

In today's technological world, mobile-based application development has become a crucial and integral element for achieving competitive advantage. Various fields have tried to create mobile applications. One widely used method is Design Thinking, which focuses on creating more innovative, user-focused, and contextual solutions. This writing reviews mobile application development using the Design Thinking approach as the main method. In this research, the author explores the basic principles of Design Thinking, its processes, and how they can be applied effectively in the stages of mobile application development. The authors also analyze the benefits derived from this approach, including improved product quality, positive user response, and the potential to meet changing market needs. The results illustrate that the Design Thinking approach is not just an application development tool, but also a philosophy that drives better innovation and more relevant solutions. This SLR will display research results to what extent the Design Thinking approach in mobile application development has been used.

Abstract

Conical rubber spring bonded memegang peran krusial dalam mendukung fungsional kereta api terutama dalam memberikan keamanan dan kenyamanan bagi penumpang kereta api. Oleh karena itu, identifikasi dini kerusakan conical rubber spring bonded menjadi penting untuk dilakukan dalam rangka menjamin conical rubber spring bonded dapat berfungsi dengan baik dalam meredam getaran pada saat kereta api beroperasi. Riset ini bertujuan mengkaji tipe kerusakan dan faktor eksternal maupun internal penyebab timbulnya kerusakan pada conical rubber spring bonded dengan menerapkan prosedur analisis kegagalan yang dilakukan dengan cara mengkarakterisasi visualisasi fisik makroskopik, sifat kimia, fisika, mekanik, dan panas dari tiga tipe produk conical rubber spring bonded bekas yang telah digunakan oleh PT Kereta Api Indonesia (Persero) yaitu tipe K, G, dan T. Hasil kajian analisis kegagalan menunjukkan bahwa jenis kerusakan meliputi muncul retak permukaan pada conical rubber spring bonded tipe K yang disebabkan karena karet alam penyusun lapisan material komposit karet tidak tahan terhadap paparan ozon. Kerusakkan mekanis (sobekan) yang parah pada conical rubber spring bonded tipe T yang mungkin disebabkan oleh faktor internal akibat pemilihan jenis dan penetapan dosis bahan kimia karet saat poduksi conical rubber spring bonded tipe T yang tidak tepat. Sementara pada conical rubber spring bonded tipe G kerusakan tampak pada komponen logam yang mengalami korosi yang menyebabkan terkelupasnya material komposit karet dari logam penyusun conical rubber spring bonded tipe G tersebut.
