Dry system delinter machine designed by Indonesian Agency for Agriculture Research and Development, Serpong, Indonesia in cooperation with Indonesian Tobacco and Fiber Crops Research Institute, Malang, Indonesia has managed to assemble a seed processing equipment delinter dry system using nitric acid. The advantages of this tool are : the process is shorter (only 2-3 hours), no sunlight compared to wet systems (sulfuric acid) which will take approximately 2-3 days and does not pollute soil and water environments. But the tool still has a weakness, where the machine is not used anymore because delinter dimensions of the machine is too big. In addition there are the seeds of cotton delinted crust layer due to heating at the contact of nitric acid vapor to cotton seeds  rudimentary. It is therefore necessary modifications to the engine of delinter the dry system. The results have been obtained by modification of the engine delinter dry system that is able to clean the rest of cotton with good results. It has also  improved capacity of 120 k /h to 150 kg/hour. Nitric acid vapor has been wetting the rest can be directed to the distillation, so as not to endanger the operator. Nitric acid requirements prior to 1 L to 120 kg of seed cotton, can be saved to 0.9 L for 150 kg of seed cotton. Engine capacity can be increased of 25% and the nitric acid need to save as much as 35%.Keywords: delinter dry systems, cotton, nitric acid vapor

Abstract

Penelitian ini merupakan studi tentang pengaruh variasi overlap sudu terhadap torsi dan daya pada kincir angin savonius tipe U. Posisi overlap sudu sangat mempengaruhi putaran poros kincir. Overlap sudu yang bisa menangkap kecepatan angin dengan baik, maka putaran poros akan semakin besar. Torsi yang semakin besar, maka daya akan semakin besar. Penelitian dilakukan dengan membuat model kincir angin Savonius tipe U dengan variasi overlap dan diberi aliran angin blower. Masing-masing overlap adalah +10 cm, +5 cm, 0 cm, -5 cm, dan -10 cm. Torsi terbesar terjadi pada overlap  -5 sebesar 0,108 Nm, sedangkan daya terbesar terjadi pada overlap +5 sebesar 11,467 Watt. Kondisi ini terjadi akibat adanya angin yang mengenai sudu tidak terbuang langsung dan tidak ada kebocoran angin ditengah.

Abstract

Minyak cengkeh merupakan salah satu minyak atsiri (essensial oil) yang banyak dibutuhkan oleh negara-negara di dunia. Minyak cengkeh bisa didapatkan dari bagian bunga, tangkai, maupun daunnya. Namun, harga bunga dan tangkai cengkeh lebih mahal dibandingkan daunnya sehingga minyak cengkeh lebih banyak dihasilkan dari daun-daun cengkeh yang kering dan telah berguguran dengan kandungan minyak berkisar pada 1-4%. Untuk menghasilkan rendemen yang tinggi pretreatment berupa pencacahan sangat dibutuhkan sehingga performansi untuk menghasilkan rendemen pada penyulingan uap yang dilakukan dapat berlangsung secara sempurna. Ukuran daun yang disuling dibedakan menjadi tiga, yaitu daun tanpa cacahan, cacahan kasar, dan cacahan halus yang dipisahkan menggunakan ayakan 12 mesh dengan ketentuan daun yang lolos ayakan merupakan daun cacahan halus sedangkan yang tidak lolos adalah daun cacahan kasar. Penyulingan ini menggunakan destilasi uap dengan waktu penyulingan selama 5 jam dalam skala laboratorium. Dalam penelitian ini rendemen dari daun cacahan kasar adalah 0,752%, cacahan halus 0,394%, dan tanpa cacahan 0,165%. Cacahan kasar memberikan hasil rendemen tertinggi dibandingkan cacahan halus dan tanpa pencacahan. Kata kunci: Minyak Atsiri, Minyak Cengkeh, Pencacahan Penyulingan
