Abstract

The testing process is not only useful for testing existing features, but also for finding errors on websites and mobile applications. It also provides feedback to the developer about the application being tested. To test large scale applications, a test automation is needed so that testing can be done more efficiently and effectively. Katalon Studio is an automation testing tool developed by Katalon LLC to automate testing on websites, API's and mobile applications. The programming languages used to create scripts in Katalon Studio are Groovy, Java, and Javascript. The scripting technique provided by Katalon Studio is a keyword driven approach where keywords in the method of Katalon Studio are used to represent the actions performed by tester on the application being tested. Katalon Studio will also facilitate tester in documenting testing results or test reports in the form of charts, graphs, and detailed reports using Katalon Analytics. The results of the testing show that the use of Katalon Studio helps both beginner and experienced tester create and design automation testing on websites, APIs, and mobile applications with spy and record utilities features. Katalon Studio also provides interactive test reports in the form of graphic visualization. From the results of API testing, it can be concluded that Katalon Studio makes it easy for tester to do end to end API testing without additional integration with other software.

Abstract

Keeping animals is a very fun hobby because pets can be entertainment in itself to relieve fatigue from daily activities. But there are certain times, the owner doesn't have time to take care of the pet, especially if there are tasks out of town for a few days, or other activities. Pet care is a solution to keep pets taken care of while their owners don't have time to take care of them. Animal care provides care facilities for pets that are deposited. Currently, many provide animal care services with the aim of helping facilitate the search for the best animal care services and according to needs. Developed a mobile application system in the form of an animal care marketplace using React Native technology. The purpose of making this system is so that animal owners can find animal care centers according to their wishes. There are two users who play a role in this system, namely animal owners and animal day care workers. The animal owner's user system can determine a message schedule to entrust animals to the care feature and choose the cage to be occupied. The advantage of this feature is that pet owners can also know the condition of their pets, because each officer will send information. Through testing this system, it is known that there are about 73% of users who want to use this system. This system helps people who have pets not to worry about doing care.

Abstract

Sebuah perusahaan produsen MSG menghadapi tantangan dalam pemenuhan pesanan yang tidak menentu, kendati memiliki kapasitas produksi yang memadai. Kendala ini bersumber dari penentuan kuantitas bahan baku yang kurang efisien untuk melayani permintaan pasar domestik dan global, sehingga menimbulkan beban biaya penyimpanan yang besar dan ketidakmampuan untuk berproduksi sesuai permintaan. Penelitian ini mengkaji permasalahan manajemen persediaan yang dihadapi oleh sebuah perusahaan multinasional produsen Monosodium Glutamate (MSG) di Indonesia. Perusahaan mengalami tantangan signifikan akibat permintaan produk yang sangat fluktuatif, terutama dari pasar ekspor, yang seringkali menyebabkan ketidakmampuan memenuhi pesanan secara konsisten. Kondisi ini menimbulkan dilema operasional: kekurangan stok bahan baku menghambat proses produksi dan menyebabkan kelangkaan produk di pasar domestik, sementara persediaan yang berlebih mengakibatkan pembengkakan biaya penyimpanan yang signifikan. Masalah ini diperparah oleh karakteristik pasokan tiga jenis bahan baku utama (A, B, dan C) yang bersifat musiman dan memiliki karakteristik yang berbeda-beda. Tujuan utama dari penelitian ini adalah untuk mengoptimalkan tingkat persediaan bahan baku guna meminimalkan total biaya persediaan melalui penerapan metode peramalan (forecasting) yang akurat dan model Economic Order Quantity (EOQ). Hasil analisis menunjukkan bahwa metode peramalan yang paling sesuai adalah Moving Average dengan periode 8 bulan (MA=8) untuk permintaan domestik dan periode 6 bulan (MA=6) untuk permintaan ekspor. Implementasi model EOQ menunjukkan bahwa total biaya persediaan dapat ditekan secara drastis dari kondisi aktual perusahaan sebesar Rp 1.818.914.075 menjadi Rp 1.337.397.305. Dengan demikian, penelitian ini menyimpulkan bahwa penerapan metode EOQ berpotensi memberikan efisiensi biaya yang sangat signifikan, dengan total penghematan mencapai Rp 481.516.770. Implementasi model ini dapat membantu perusahaan menyeimbangkan ketersediaan stok untuk pasar ekspor dan domestik, sekaligus meningkatkan efisiensi operasional dan profitabilitas secara keseluruhan.

Abstract

Madura stalls, as part of informal micro-enterprises, play a vital role in meeting the needs of urban communities. However, most still operate without a structured strategic management system and performance measurement. This situation makes it difficult for business owners to monitor efficiency, understand customer satisfaction, and plan for long-term competitiveness. On the other hand, there is a research opportunity to adapt modern management methods, such as the Balanced Scorecard (BSC) and Value Engineering (VE), to suit the context of simple yet influential small businesses. This study aims to design a performance measurement system by integrating VE into the BSC framework at a Madura stall in Klampis, Surabaya. The method used is an exploratory case study with a mixed-methods approach, involving owners (n = 5), employees (n = 10), and customers (n = 30). Data were collected through interviews, observations, questionnaires, and document review. Data were then analyzed using the Function Analysis System Technique (FAST), KPI formulation, AHP weighting, and performance evaluation. The study results show that several key performance indicators exceeded targets, such as daily sales volume (226.7%), number of customers (200%), and net profit (120%). These achievements confirm that the integration of the BSC and VE can improve cost efficiency, strengthen customer orientation, and provide a clearer strategic direction for informal micro-enterprises. This study contributes by providing a contextually relevant performance measurement framework and opens up opportunities for further research on the application of the BSC and VE to other micro-enterprise units.
