The solar parabolic trough collector technology is one of the most reliable technologies in the field of solar thermal. This is due to the fact that temperatures as high as 400o C can be achieved using this technology. The energy development from these systems used for hot water production, process steam requirement, power generation and many more. Majorly they have wide applications in cooking. They are also used to generate steam at higher temperatures which is used to run a subsequent engine. In the present Paper, performance analysis of copper absorber tube parabolic collector is done for different parameters of the system such as Reflector sheet material, heat transfer fluid, Period of Sun Incidence at different levels the output responses such as Out Temperature of heat transfer fluid, Discharge, and Thermal Efficiency are recorded for each run. The optimization method S/N ratio analysis is applied for determining the optimal parameters level for better responses and the optimum results are confirmed experimentally

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.
