Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Produktivitas tanaman kelapa sawit sangat dipengaruhi oleh kualitas benih yang digunakan. Pemakaian benih kelapa sawit bersertifikat dipercayai oleh petani yang kritis dalam memberikan produktivitas tanaman kelapa sawit yang bermutu dan kontinyu. Sikap dan kepuasan petani dalam menggunakan benih kelapa sawit bersertifikat merupakan hal yang perlu dicermati untuk memahami keinginan petani. Penelitian ini dirancang untuk mengamati hal tersebut. Sikap petani dianalisis dengan menggunakan pendekatan multiatribut fishbean sedangkan kepuasan dianalisis dengan menggunakan Important Performance Analysis (IPA) dan Customer Satisfied Index (CSI). Berdasarkan penelitian diketahui bahwa atribut-atribut yang menentukan sikap dan kepuasan petani adalah hasil panen, ketahan terhadap hama dan penyakit, umur tanaman, daya tumbuhbenih, efisiensi penggunaan pupuk, jenis varietas, ukuran benih, sertifikasi benih, harga benih, harga Tandan Buah Segar (TBS), kemudahan dalam akses benih, stok benih, kemudahan dalam menjual TBS, dan promosi toko.Analisis multiatribut Fishbeinmenunjukkan sikap netral terhadap benih kelapa sawit bersertifikat (76 persen). Sementara hasil CSI menunjukkan bahwa 70.04 persen petani merasa puas atas atribut-atribut pada benih kelapa sawit bersertifikat.
