Amasahani y’ibara ry’agahama akenshi akozwe mu cuma c’ivyuma, kandi ibihengeri bikwiye vyo guhumanya umwuka biraguma hagati y’ibipande kugira ngo umuyaga ucire muri ivyo bihengeri mu gice c’amavuta kugira ngo umuriro usha. Icumba co guhumanya umwuka gigabanyijwe n’umuyaga gishobora guhindurwa, akenshi gitangwa munsi y’uruzitiro kugira ngo kigenzure uburyo bwo guturika 1.
Ubwoko n'ugukoresha isahani y'ibara
Hari ubwoko bwinshi bw’isahani y’ivyuma, hakurikijwe uburyo butandukanye bwo gukora, bushobora guca mu bice bihoraho, bigendagenda, bihinduranya, ukunyiganyiga n’ubwoko bw’ibifungurwa.
