Abstract

Pembuatan kain tenun terdapat flow process sebagai berikut; mulai dari order konsumen, penyediaan bahan baku, bahan baku masuk ke mesin warping, lalu diproses di sizing, setelah itu masuk proses reaching atau tying, lalu memasuki proses pertenunan, setelah menjadi kain, dibawa ke inspecting, folding, grading lalu packing, dan di kirim ke konsumen. Pada saat melaksanakan proses produksi, untuk mendapatkan kualitas yang baik diperlukan suatu perencanaan produksi, pengendalian produksi dan pemeliharaan mesin, serta pengendalian mutu pada raw material, proses produksi dan produk jadi. Dalam produksi kain tenun banyak faktor yang dapat mempengaruhi kualitas dan kuantitas produksi, salah satunya adalah permasalahan benang lusi lengket. Beberapa faktor penyebab benang lusi lengket diantaranya, faktor material; hasil hanian ada putus tidak disambung, faktor method; size pick up melebihi standar, faktor mesin; squeezing roll aus atau miring, panas temperatur cylinder kurang, sizebox kotor, faktor manusia; kurang kontrol, faktor lingkungan; mesin kotor.

Abstract

Energy is a basic need that can support many things. Fossil energy accounts for 80% of the world's needs, this energy has an environmental impact. One of the new renewable energy (EBT), namely fuel cell, in its development has obstacles where the catalyst is expensive. This study aims to determine the characteristics of pyrolysis activated carbon as a catalyst supporting carbon fuel cell. corn cob waste is processed into activated carbon by being influenced by temperature and holding time. The temperature variation of the study was 400° and 500° with a residence time of 60 Minutes. The resulting carbon is tested proximate to determine the water content, ash content, volatiles, and bound carbon content. Based on the proximate test, the temperature variation of 400 ° produces the highest moisture content in the figure of 8.8% but still meets SNI No.06-3730-1995. The temperature variation of 500° produces the highest bound carbon at 74.35% in accordance with SNI No.06-3730-1995 so that it has the potential to support fuel cell catalysts.
