Menghitung Nilai TOPSIS
KESIMPULAN DAN SARAN
5.1. Kesimpulan
Berdasarkan analisis data yang telah dilakukan dalam penelitian ini, maka diperoleh kesimpulan sebagai berikut.
1. Terjadi bleeding pada varian R6 dan R8 dimana kandungan glass powder sangat tinggi. Karena itu bisa disimpulkan bahwa penambahan glass powder tidak mengatasi masalah bleeding. Seperti penelitian terdahulu yang membuktikan bahwa glass powder menyerap sedikit air.
2. Menurut hasil single-response, silica fume memberikan pengaruh yang besar terhadap slump flow, dengan kata lain glass powder juga mempengaruhi slump flow. Dimana menurut penelitian sebelumnya, membuktikan bahwa dengan penambahan glass powder, mampu meningkatkan workability pada beton.
3. Perubahan jumlah agregat sangat mempengaruhi flow ability dari beton. Dengan perubahan sebesar 10% memberikan efek sebesar 0,047 pada test L-box menurut perbandingan hasil single-response dan multi-response. 4. Perubahan viscocrete memberikan pengaruh pada porositas seperti yang
ditunjukkan pada single-response (dengan kadar 1,2%) dan multi-response (dengan kadar 1%), dimana estimasi porositas pada kadar viscocrete lebih banyak menunjukkan porositas yang lebih kecil.
5. Komposisi dengan kerikil 45%, glass powder 15%, silica fume 40% dan viscocrete 1% menunjukkan hasil yang paling optimum dalam tiap respon. Hasil konfirmasi multi-respon masih dalam range.
5.2. Saran
Berdasarkan analisis data yang telah dilakukan dalam penelitian ini, maka diberikan saran sebagai berikut.
1. Perlu dilakukan percobaan tanpa penggunaan plastimen vz, karena terjadinya gelembung dicurigai akibat kombinasi dari glass powder, viscocrete, dan plastimen vz.

2. Perlu dilakukan trial taguchi dengan level dan faktor yang berbeda untuk mendapatkan signifikansi dan optimasi terhadap V-funnel test.
