Mobile apps are very widely used because they are easy and almost everyone in Indonesia already has a smartphone. Mobile app or commonly known as an application on a smartphone is one of the businesses that is currently being developed by many people to meet human needs in many ways. Hasil dari penelitian ini adalah dihasilkan sebuah aplikasi forecasting penjualan produk UMKM menggunakan algoritma regresi linear yang dapat digunakan oleh pelaku UMKM untuk menentukan rencana penjualan produk dan prediksi penjualan pada bulan berikutnya. Langkah-langkah metode tersebut terdiri dari fase inception, fase elaboration, fase construction dan fase transition. Metode pengembangan sistem menggunakan metode RUP yang berpusat pada permasalah yang ada. Metode ini dianggap cukup optimal dalam melakukan peramalan atau prediksi penjualan.

Metode yang digunakan untuk melakukan peramalan adalah metode regresi linear. Oleh karena itu dibutuhkan sebuah aplikasi peramalan produk yang dapat digunakan oleh pelaku UMKM untuk memperkiraan persediaan barang dimasa yang akan datang. UMKM mengalami kesulitan untuk menentukan rencana penjualan. Kebijakan untuk untuk mengendalikan pergerakan virus Covid-19 dengan menerapkan pembatasan kegiatan masyarakat berdampak pada terganggunya aktifitas ekonomi terkhusus pada sector UMKM. The research results show that graph testing, equivalence partitioning, and boundary value analysis will be able to help the process of making test cases and make testing simpler, There are errors in testing and are included in the defect-list, the test results also show that the fulfillment of user needs for public users with a value 0.90, user registers/member with a value of 1.00, students with a value of 0.90, lecturers with a value of 0.82 and admin with a value of 0.84 are classified as good because the degree of value in each user module is greater than 0.8. Testing the Black-Box Source Code Bank Programming uses 3 methods, namely 1) Graph-based testing, 2) Equivalence Partitioning, and 3) Boundary Value Analysis. It is necessary to do various evaluations of the quality of the application in order to match the expectations of the user, one of which is to analyze the quality of the application using the Black-Box Testing method. In the process of developing Source Code Bank Programming is still in the prototype stage and further development is still being carried out so that it can be competitively competitive in the world. The Source Code Bank Programming application that the researchers built uses Borland Delphi which functions to support software learning activities and as a reference for software developers, especially the Delphi programming language.
