BIOGAS KOTORAN SAPI PDF

Undergraduate thesis, Institut Teknologi Sepuluh Nopember. Sumber daya minyak dan gas alam dunia yang berasal dari energi fosil semakin berkurang. Sehingga pengembangan penelitian sumber energi alternatif semakin sering dilakukan, salah satunya adalah produksi biogas. Bahan baku alternatif yang potensial untuk menghasilkan gas metana adalah limbah kulit kopi. Kulit kopi dipilih karena merupakan limbah yang banyak dihasilkan dari proses pengolahan biji kopi. Kopi sendiri merupakan komuditas unggulan di Indonesia.

December 31, Journal article Open Access. Rosiana Indrawati. The scarcity of energy sources, especially fuel oil BBM has become a world problem. The abundant cattle dung in the community has not been optimally utilized. The aim of this research is to know the effect of speed and duration of stirring to biogas volume and final BOD concentration on cow manure biogas mixturetannery industry wastewater IPK. The experiment used biodigester reactor as much as 5 pieces, 1 as the controller without stirring and 4 others as the test digester with stirring.

IPK 0 as a control digester without stirring. Variation of stirring speed 5 and 10 rpm and stirring time 10 and 15 minutes.

The volume of biogas is measured for 20 days. BOD levels are measured on the last day of the fermentation process. The experiment showed that the highest biogas volume was found on PK10L10 test digester that was mixture of cow manureandtannery industry wastewater IPK with variation of 10 rpm and duration of stirring 10 minutes ie 0.

The stirring process has a significant effect on biogas production and decrease of BOD concentration in the digester. Files Name Size 5.

KINETIKA PEMBUATAN BIOGAS DARI SUBSTRAT KULIT KOPI DENGAN MIKROORGANISME KOTORAN SAPI DAN RUMEN

Kotoran sapi adalah limbah hasil pencernaan sapi dan hewan dari subfamili Bovinae lainnya kerbau , yak , bison. Kotoran sapi memiliki warna yang bervariasi dari kehijauan hingga kehitaman, tergantung makanan yang dimakan kerbau. Setelah terpapar udara, warna dari kotoran sapi cenderung menjadi gelap. Kotoran sapi biasanya digunakan sebagai pupuk kandang. Di berbagai tempat di dunia, kotoran sapi yang dikeringkan digunakan sebagai bahan bakar.
