Abstract

The rubber plantation of PTPN IX Banyumas has a 1.202 Ha area with
rubber seeds that have not been untapped by people. It is likely due to the
people's lack of knowledge on rubber seeds' benefits and on how to process
them to be alternative food. A rubber seed may contain 15.9% carbohydrate,
27% protein, 32.3% fat, 3.96% ash per 100 gram of rubber seeds flesh, 0.85
mg Ca mineral per gram of rubber seed, 0.01 Fe, and 9.29 mg Mg. Based on
the previous statement, therefore, the purpose of this research was to find out
the proximate content in cyanide free-rubber seed yoghurt (Hevea
brasiliensis) and to fmd out its storage time toward Escherichia coli bacteria.
The procedures of this research included rubber seed sampling, sample
preparation, and yoghurt making, and the analysis of proximate and
Escherichia coli bacteria on the yoghurt. The proximate analysis consisted of
water level analysis using constant weight method, ash level analysis using
furnace method, fat level analysis using soxhlet method, protein level
analysis using kjeldahl method, and carbohydrate level analysis using
difference method, while the analysis of Escherichia coli bacteria used MPN
(Most Probable Number)method. The results showed that the average of
water level =86,66%, ash level= 0,07%, protein level = 0,602%, fat level =
0,812%, and carbohydrate level= 0,80%, while the average ofHCN level was
0,0015%. Rubber seed yogurt can be consumed with in 5 days after its
making.
