BAB 6. KESIMPULAN DAN SARAN
6.2. Saran
Setelah dilakukan penelitian, dapat disampaikan beberapa saran sebagai berikut:
1. Perlu dilakukan penelitian lebih lanjut seperti uji in vivo dan uji lainnya agar air perasan jeruk nipis dapat diketahui pengaruhnya dari berbagai aspek pengujian.
2. Perlu dilakukan penelitian lebih lanjut mengenai pengaruh air perasan jeruk nipis tidak hanya terhadap bakteri lainnya tetapi juga jamur dan parasit.
