  1.Konversi Suhu

Rumus:

​​Fahrenheit = (9/5) * Celsius + 32 Kelvin = Celsius + 273.15 Reamur = (4/5) * Celsius

 

Source Code;

package com.example.latihan5gend

import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import android.widget.TextView
import androidx.activity.enableEdgeToEdge
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.ViewCompat
import androidx.core.view.WindowInsetsCompat

class Konversi_suhu : AppCompatActivity() {
    private lateinit var etSuhu: EditText
    private lateinit var btnFahrenheit: Button
    private lateinit var btnKelvin: Button
    private lateinit var btnReamur: Button
    private lateinit var txtHasil: TextView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContentView(R.layout.activity_konversi_suhu)

        etSuhu = findViewById(R.id.etSuhu)
        btnFahrenheit = findViewById(R.id.btnFahrenheit)
        btnKelvin = findViewById(R.id.btnKelvin)
        btnReamur = findViewById(R.id.btnReamur)
        txtHasil = findViewById(R.id.txtHasil)

        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets ->
            val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars())
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom)
            insets
        }
        btnFahrenheit.setOnClickListener() {
            val hasil = (9 / 5) * etSuhu.text.toString().toInt() + 32
            txtHasil.setText("Hasil Konversinya = " + hasil)
        }

        btnKelvin.setOnClickListener() {
            val hasil = etSuhu.text.toString().toInt() + 273.15
            txtHasil.setText("Hasil Konversinya = " + hasil)
        }

        btnReamur.setOnClickListener() {

            txtHasil.setText("Hasil Konversinya = " + hasil)
        }
    }
}

package com.example.latihan5gend

import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import android.widget.TextView
import androidx.activity.enableEdgeToEdge
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.ViewCompat
import androidx.core.view.WindowInsetsCompat

class Diskon : AppCompatActivity() {
    private lateinit var etTotalBelanja: EditText
    private lateinit var btnDiskon: Button
    private lateinit var txtHasilDiskon: TextView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContentView(R.layout.activity_diskon)


        etTotalBelanja = findViewById(R.id.etTotalBelanja)
        btnDiskon = findViewById(R.id.btnHitungDiskon)
        txtHasilDiskon = findViewById(R.id.txtHasilDiskon)

        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets ->
            val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars())
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom)
            insets
        }
        btnDiskon.setOnClickListener() {
            val totalBelanja = etTotalBelanja.text.toString().toInt()

            if (totalBelanja >= 100000 && totalBelanja <= 500000) {
                val diskon = etTotalBelanja.text.toString().toInt() * 0.1
                txtHasilDiskon.setText("Diskon anda sebesar " + diskon)

            } else {
                txtHasilDiskon.setText("Anda tidak mendapatkan diskon")
            }
        }
    }
}

 

3. Menghitung luas permukaan dan volume

Rumus:

- Luas permukaan = 2(p.l + p.t + l.t)

- Volume = p.l.t 

Source Code: 

package com.example.latihan5gend

import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import android.widget.TextView
import androidx.activity.enableEdgeToEdge
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.ViewCompat
import androidx.core.view.WindowInsetsCompat

class Bangun_Ruang : AppCompatActivity() {
    private lateinit var etPanjang: EditText
    private lateinit var etLebar: EditText
    private lateinit var etTinggi: EditText
    private lateinit var btnLuasPermukaan: Button
    private lateinit var btnVolume: Button
    private lateinit var txtHasilBangunRuang: TextView
    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContentView(R.layout.activity_bangun_ruang)

        etPanjang = findViewById(R.id.etPanjang)
        etLebar = findViewById(R.id.etLebar)
        etTinggi = findViewById(R.id.etTinggi)
        btnLuasPermukaan = findViewById(R.id.btnLuasPermukaan)
        btnVolume = findViewById(R.id.btnVolume)
        txtHasilBangunRuang = findViewById(R.id.txtHasilBangunRuang)

        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets ->
            val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars())
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom)
            insets
        }
        btnLuasPermukaan.setOnClickListener() {
            val panjang = etPanjang.text.toString().toInt()
            val lebar = etLebar.text.toString().toInt()
            val tinggi = etTinggi.text.toString().toInt()
            val hasil = 2 * (panjang * lebar + panjang * tinggi + lebar * tinggi)
            txtHasilBangunRuang.setText("Luas Permukaan Balok adalah " + hasil)
        }

        btnVolume.setOnClickListener() {
            val panjang = etPanjang.text.toString().toInt()
            val lebar = etLebar.text.toString().toInt()
            val tinggi = etTinggi.text.toString().toInt()
            val hasil = panjang * lebar * tinggi
            txtHasilBangunRuang.setText("Volume Balok adalah " + hasil)
        }

    }
}

 

4. Menentukan bilangan Ganjil atau Genap

Source code:

package com.example.latihan5gend

import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import android.widget.TextView
import androidx.activity.enableEdgeToEdge
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.ViewCompat
import androidx.core.view.WindowInsetsCompat

class Bilangan : AppCompatActivity() {

    private lateinit var etBilangan : EditText
    private lateinit var btnDeteksi : Button
    private lateinit var txtHasilBilangan : TextView

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContentView(R.layout.activity_bilangan)
        etBilangan = findViewById(R.id.etBilangan)
        btnDeteksi = findViewById(R.id.btnDeteksi)
        txtHasilBilangan = findViewById(R.id.txtHasilBilangan)

        btnDeteksi.setOnClickListener() {
            val angka = etBilangan.text.toString().toInt()

            if ( angka % 2 == 0 ) {
                txtHasilBilangan.setText("Bilangan " + angka + " adalah bilangan genap")
            } else {
                txtHasilBilangan.setText("Bilangan " + angka + " adalah bilangan ganjil")
            }
        }

        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets ->
            val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars())
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom)
            insets
        }
    }
}
