-Tip Time - Solution Code
+Kalkulator BMI
-=================================
+===============
+Langkah-langkah:
 
-Solution code for the [Android Basics with Compose](https://developer.android.com/courses/android-basics-compose/course): Tip Time app.
+1. Clone Repository Project
+Saya meng-clone repository project dari GitHub menggunakan Android Studio untuk dijadikan dasar pengerjaan tugas.
 
+2. Modifikasi Tampilan Aplikasi
+Saya meminta bantuan ChatGPT dan DeepSeek untuk memberikan saran tampilan aplikasi agar lebih menarik. Setelah itu, saya menyesuaikan tampilan sesuai arahan yang diberikan.
 
-Introduction
+3. Mengubah Icon Aplikasi (APK)
-------------
+Saya mengganti icon aplikasi melalui fitur Image Asset di Android Studio dengan icon baru sesuai arahan dari ChatGPT.
-The Tip Time app contains various UI elements for calculating a tip,
-teaching about user input, and State in Compose.
 
+4. Review dan Uji Coba
+Setelah perubahan selesai, saya menjalankan aplikasi untuk memastikan tampilan dan icon sudah berubah dengan baik.
 
-Pre-requisites
+Petunjuk lebih detil dapat dibaca di
---------------
+https://docs.google.com/document/d/1iGiC0Bg3Bdcd2Maq45TYkCDUkZ5Ql51E/edit?rtpof=true
-* Experience with Kotlin syntax.
-* How to create and run a project in Android Studio.
 
-
+Starter dimodifikasi dan terinspirasi dari:
-Getting Started
+https://developer.android.com/codelabs/basic-android-compose-calculate-tip#0
----------------
-1. Install Android Studio, if you don't already have it.
-2. Download the sample.
-3. Import the sample into Android Studio.
-4. Build and run the sample.
