Abstract

Dalam kegiatan produksi, industri pangan selalu menghasilkan limbah, baik berupa limbah padat, limbah cair maupun gas. Salah satu cara pengolahan limbah cair indutri pangan adalah dengan cara biologi, menggunakan mikroorganisme selektif sesuai dengan karakteristik limbah industri pangan yang diolah. Pada kegiatan ini telah dilakukan penelitian penggunaan beberapa jenis starter yang berasal dari lumpur limbah cair yang bersala dari industri tahu, bihun dan roti. Penelitian ini bertujuan untuk mendapatkan produk starter mikroorganisme siap pakai dengan biaya murah. Penelitian dilakukan dengan menggunakan 3 faktor yakni A,B dan C dimana faktor A adalah jenis limbah cair, yaitu limbah cair industri tahu, limbah cair industri bihun dan limbah cair industri roti. Faktor B adalah jenis starter yang digunakan yakni lumpur aktif/sludge, phenobac dan kontrol. SEdangkan faktor C adalah waktu inkubasi, 0,2m4 dan 6 hari. Hasil penelitian menunjukkan bahwa lumpur aktif dari industri bihun dapat digunakan untuk mengolah limbah industri pangan lainnya. Tingkat penurunan BOD tertinggi adalah perlakuan limbah cair industri tahu dengan menggunakan lumpur aktif industri bihun selama 6 hari dapat menurunkan BOD dari 2667,4 mg/l menjadi 941,2 mg/l (64,71%). Untuk TSS tingkat penurunan tertinggi adalah air limbah bihun penuruan TSS sebesar 83,23%.

Abstract

Cocodust is one of the waste of coconut industry which consist of some minerals and it has bulky volume, it means that cocodust has much air space whice is good for medium of plantation. Cocodust has been exported to Europe for plantation medium. Unfortunetly that cocodust consist of highly certai mineral which do not need by plant therefore it should be reduce their component as their standard for plantation medium. The experiment of cocodust was carried out by rinsing of cocodust in water to reduce their mineral such as sodium(Na) and dryed it with artificial dryer and sun drying. The result of treated cocodust mixed with different propotion of soil and used to grow capsicum plant. The effect of the use of cocodust in the growing of capsicum plant was observed their height. The result showed that rinsing of cocodust can reduce sodium content about 90%, drying by using rotary dryer can reduce drying time and the best treatment for planting was propotion beetween cocodust and soil was 1:1.

Abstract

Methyl ricinoleate was produced by methanolysis process from castor oil using KOH and NaOH as catalysts. The esterification process was carried out at the temperature of 30 derajat and 70 derajat celcius for 1, 2, and 3 hrs respectively. The product was analyses using GC for the esterification process. The iod value saponification value, and acid number were also analysed. Potassium hydroxide gave higher result in comparison to sodium hydroxide as catalyst for the process duration of 3 hrs. The specific gravity of the product ranged from 0.8903 to 0.9608 and the refractive index was between 1.3810 and 1.4500.
(Waste Water Treatment of Tofu Industries by Chemical and Physical(Aeration ) Processes to the Decreasing of BOD5 and Suspended Solid) Eko Susanto; Amelia Rachmatunisa

Abstract

The waste water of tofu industries cause enviromental poblem due to its high BOD and suspended solid values. The decomposition of organic matters in the waste water will result in cloudness of the water and awful smell. Therefore it is necessary to reduce their organic matters by coagulation process using chemicals and continued solid values. The result showed that the aeration, the lower the BOD and suspended values would be. The 22 hours aeration would decrease the BOD value up to 84.36% and suspended solids value op to 91.32%.
