The vote counting method in the 2019 Election will use Sainte Lague. This method was introduced by Andre Sainte Lague, a French mathematician. This method divides the seat by dividing the incoming sound to 1,3,5,7 dst. In contrast to previous electoral methods, where in the previous elections BPP (voter divider number) was used.

How to calculate the seat is very simple.

EXAMPLE:

If in one plot there is allocation of 7 seats, with the vote on the electoral dumpil:

1. A total party won 28,000 votes.
2. Party B won 15,000 votes.
3. Party C won 10,000 votes.
4. Party D earned 6,000 votes.
5. Party E 3000 votes.

The First Chair

Then the first chair is obtained by division 1.

1. Party A 28,000 / 1 = 28,000.
2. Party B 15,000 / 1 = 15,000
3. Party C 10,000 / 1 = 10,000
4. Party D 6,000 / 1 = 6,000
5. Party E 3,000 / 1 = 3,000

So the first seat belongs to party A with 28,000 votes.

The Second Chair

For seat 2, because A had already won in the 1st division.
Then next, A will be divided by 3, while the others are still divided by 1.

The 2nd seat count is:

1. Party A 28,000 / 3 = 9.333
2. Party B 15,000 / 1 = 15,000
3. Party C 10,000 / 1 = 10,000,
4. Party D 6,000 / 1 = 6,000
5. Party E 3,000 / 1 = 3,000

Then the 2nd seat belongs to party B with 15,000 votes.

Third Chair

Now the 3rd seat, Party A and B have got seats with division 1, then they remain with division 3, while the other party votes still with the 1st division.

Then the 3rd seat count is:

1. Party A 28,000 / 3 = 9.333.
2. Party B 15.000 / 3 = 5,000.
3. Party C 10,000 / 1 = 10,000
4. Party D 6,000 / 1 = 6,000
5. Party E 3,000 / 1 = 3,000

So here the 3rd seat belongs to the C party with 10,000 votes.

Fourth Chair

The vote count for the 4th, A, B and C seats has got seats with division 1, then they will go into division 3.

1. Party A 28,000 / 3 = 9.333
2. Party B 15.000 / 3 = 5,000
3. Party C 10,000 / 3 = 3,333
4. Party D 6,000 / 1 = 6,000
5. Party E 3,000 / 1 = 3,000

Then the 4th seat belongs to A with 9,333 votes.

The Fifth Seat

Going to seat 5, Party A has got 1st and 3rd vote, then A will be divided into 5, B and C divided by 3, while D and E are still on the 1st division.

The 5th seat count is:

1. Party A 28,000 / 5 = 5,600.
2. Party B 15.000 / 3 = 5,000
3. Party C 10,000 / 3 = 3,333
4. Party D 6,000 / 1 = 6,000
5. Party E 3,000 / 1 = 3,000

So party D gets the 5th seat with 6,000 votes.

Sixth Chair

Seats 6, A divided by 5. B, C and D divided by 3, and E is still divided by 1.

1. Party A 28,000 / 5 = 5,600.
2. Party B 15.000 / 3 = 5,000.
3. Party C 10,000 / 3 = 3,333
4. Party D 6,000 / 3 = 2,000
5. Party E 3,000 / 1 = 3,000

Here A gets a seat again, because the voice is 5,600.

Seventh Chair

While the calculation of the last seat, A gets a division of 7, because the division of 1.3 and 5 has produced seats.

Then the calculation of the chair to 7 is:

1. Party A 28,000 / 7 = 4,000
2. Party B 15.000 / 3 = 5,000.
3. Party C 10,000 / 3 = 3,333
4. Party D 6,000 / 3 = 2,000
5. Party E 3,000 / 1 = 3,000

So party B gets the last seat with 5,000 votes.

Total seat acquisition:

1. Party A = 3 seats.
2. Party B = 2 seats.
3. Party C = 1 seat.
4. Party D = 1 seat.
5. Party E = 0 seats.

INA

Metode penghitungan suara pada Pemilu 2019 nanti akan menggunakan Sainte Lague. Metode ini diperkenalkan oleh Andre Sainte Lague, Ahli matematika asal Perancis. Metode ini membagi kursi dengan cara membagi suara yang masuk menjadi 1,3,5,7 dst. Berbeda dengan metode pada pemilu yang sebelumnya, dimana pada pemilu yang lalu digunakan BPP (bilangan pembagi pemilih).

Cara penghitungan kursinya sangat simple.

CONTOH:

Apabila dalam satu dapil ada alokasi 7 kursi, dengan perolehan suara pada dapil tersebut:

1. Partai A total meraih 28.000 suara.
2. Partai B meraih 15.000 suara.
3. Partai C meraih 10.000 suara.
4. Partai D meraih 6.000 suara.
5. Partai E 3000 suara.

Kursi Pertama

Maka kursi pertama didapat dengan pembagian 1.

1. Partai A 28.000/1 = 28.000.
2. Partai B 15.000/1 = 15.000
3. Partai C 10.000/1 = 10.000
4. Partai D 6.000/1 = 6.000
5. Partai E 3.000/1 = 3.000

Jadi kursi pertama adalah milik partai A dengan 28.000 suara.

Kursi Kedua

Untuk kursi ke 2, dikarenakan A tadi sudah menang di pembagian 1.
Maka berikutnya, A akan dibagi 3, sedangkan yang lain masih dibagi 1.

Perhitungan kursi ke-2 adalah:

1. Partai A 28.000/3 = 9.333
2. Partai B 15.000/1 = 15.000
3. Partai C 10.000/1 = 10.000,
4. Partai D 6.000/1 = 6.000
5. Partai E 3.000/1 = 3.000

Maka kursi ke 2 adalah milik partai B dengan 15.000 suara.

Kursi Ketiga

Sekarang kursi ke 3, Partai A dan B telah mendapatkan kursi dengan pembagian 1, maka mereka tetap dengan pembagian 3, sedangkan suara partai lain masih dengan pembagian 1.

Maka perhitungan kursi ke 3 adalah:

1. Partai A 28.000/3 = 9.333.
2. Partai B 15.000/3 = 5.000.
3. Partai C 10.000/1 = 10.000
4. Partai D 6.000/1 = 6.000
5. Partai E 3.000/1 = 3.000

Maka disini kursi ke 3 milik partai C dengan 10.000 suara.

Kursi Keempat

Perhitungan suara untuk kursi ke 4, A, B dan C telah mendapat kursi dengan pembagian 1, maka mereka akan masuk ke pembagian 3.

1. Partai A 28.000/3 = 9.333
2. Partai B 15.000/3 = 5.000
3. Partai C 10.000/3 = 3.333
4. Partai D 6.000/1 = 6.000
5. Partai E 3.000/1 = 3.000

Maka kursi ke 4 adalah milik A dengan 9.333 suara.

Kursi Kelima

Masuk ke kursi ke 5, Partai A sudah mendapat kursi hasil pembagian suara 1 dan 3, maka selanjutnya A akan dibagi 5, B dan C dibagi 3, sementara D dan E masih pada pembagian 1.

Penghitungan kursi ke 5 adalah:

1. Partai A 28.000/5 = 5.600.
2. Partai B 15.000/3 = 5.000
3. Partai C 10.000/3 = 3.333
4. Partai D 6.000/1 = 6.000
5. Partai E 3.000/1 = 3.000

Maka partai D mendapatkan kursi ke 5 dengan 6.000 suara.

Kursi Keenam

Kursi ke 6, A dibagi 5. B,C dan D dibagi 3, dan E masih dibagi 1.

1. Partai A 28.000/5 = 5.600.
2. Partai B 15.000/3 = 5.000.
3. Partai C 10.000/3 = 3.333
4. Partai D 6.000/3 = 2.000
5. Partai E 3.000/1 = 3.000

Disini A kembali mendapat kursi, karena suaranya ada 5.600.

Kursi Ketujuh

Sedangkan perhitungan kursi terakhir, A mendapatkan pembagian 7, karena pembagian 1,3 dan 5 telah menghasilkan kursi.

Maka perhitungan kursi ke 7 adalah:

1. Partai A 28.000/7 = 4.000
2. Partai B 15.000/3 = 5.000.
3. Partai C 10.000/3 = 3.333
4. Partai D 6.000/3 = 2.000
5. Partai E 3.000/1 = 3.000

Maka partai B mendapat kursi terakhir dengan 5.000 suara.

Total perolehan kursi:

1. Partai A = 3 kursi.
2. Partai B = 2 kursi.
3. Partai C = 1 kursi.
4. Partai D = 1 kursi.
5. Partai E = 0 kursi.
