Research about the effect of greenpeal sprout Phaseolus radiatus L. on the spermatozoa density of Mus musculus L. has been done. The purpose of this research was to know the effect of greenpeal sprout Phaseolus radiatus L. on the spermatozoa density of Mus musculus L. Mice is feeded with greenpeal sprout for 21 days. The sperm is collected from cauda of epididimis diluted physiological solution and counted using haemocytometer. The result showed that micefeeding with greenpeal sprout could increase the density of its spermatozoa. It showed from increase the density of its spermatozoa from 11,05 million/cc sperm in control group become 11,78 million/cc sperm in treatment group by use of T test. Fidelity guarantee 95 percent explain that there are positive correlation and significant.

Biopotting was a pot of growing medium for plant seedlings that was environmentally friendly. This study analyzed the effect of biopotting quality  made from clay, fruit waste compost of rambutan, jackfruit, durian,  market compost and tapioca flour on the growth and morphological quality of jackfruit seedlings. The results of the chemical analysis of biopotting samples containing organic C ranged from 42- 44%, total N ranged from 0.21-0.35%, total P ranged from 28.14-38.25 mgkg-1, potassium (K) ranged from 0.90-1.13me/100g and pH ranged from 4.08-6.68. Physical analysis of biopotting obtained water content ranged from 2.04-3.09%, density ranged from 0.42-0.50gcm-3, water absorption ranged from 200-242% and the level of damage to all biopotting was ≤ 2% so it was included in the undamaged category. Measurement of growth and morphological quality of jackfruit seedlings aged 60 days obtained an average height ranged from 17.85-27.6cm,  an average of stem diameter ranged from 0.43-0.47cm, number of leaves ranged from 3-4 strands, root length ranged from 12.5-16.8cm and morphological quality index ranged from 0.092- 0.099. This study concluded that the best quality on M4 biopotting had a significant effect on the growth and morphological quality of the jackfruit Artocarpus heterophyllus Lamk. seedlings
