Producer gas hasil gasifikasi biomassa masih mengandung pengotor berupa abu. Pembersihan producer gas dilakukan menggunakan cyclone separator. Sebuah model cyclone separator konfigurasi standar 2D2D berdiameter 150 mm telah dibuat. Tiga variasi panjang (3/8 D; 5/8 D; 1 D) dan tiga variasi diameter (35; 70; 85) vortex finder digunakan untuk mengetahui pengaruhnya terhadap performa cyclone. Eksperimen dan simulasi CFD menggunakan Ansys Fluent telah dilakukan. Simulasi CFD bertujuan untuk mengetahui profil kecepatan didalam cyclone separator. Hasil eksperimen menunjukkan semakin panjang vortex finder, collection efficiency semakin tinggi. Hasil simulasi CFD mendukung kesimpulan hasil eksperimen. Didapatkan dimensi vortex finder optimum dengan diameter 35 mm (1/4 D) dan panjang 1D (150 mm). ...... Producer gas produced from biomass gasification still contain particulate ash. Producer gas is cleaned by use of cyclone separator. A cyclone separator model with 2D2D standard configuration with diameter150 mm was made. Three variation of length (3/8 D; 5/8 D; 1 D) and three variation of diameter (35; 70; 85 mm) of vortex finder are used to identify their influence on cyclone performance. Experimental study and CFD Simulation using Ansys Fluent were performed. CFD simulation goal is to determine the velocity profile inside cyclone separator. Experimental results shows that increasing vortex finder length can increase the collection efficiency. The optimum vortex finder dimension is 35 mm (1/4 D) in diameter and 1 D (150 mm) in length.

Fakultas X Universitas Y menetapkan “Menjadi Kiblat Riset Asia" sebagai visinya mulai periode administrasi 2008. Pimpinan Fakultas telah memulai intcrvensi untuk meningkatkan produktivitas kegiatan penelitian, namun belum semua kelompok penelitian yang berhasil terbentuk menunjukkan produktivitas yang diharapkan. Fakultas X perlu menemukan cara untuk memicu kegiatan penelitian untuk mencapai vismya. Menggunakan model system-learning link Marquardt gejala-gejala dalam Fakultas diklasifikasikan ke dalam lima subsistem (Pcmbclajaran, Organisasi, Manusia, Pengetahuan, dan Teknologi). Intervensi yang dimulai dari masalah koordinasi komunikasi informasi dan pengetahuan penelitian (subsistem organisasi) yang berbasis tcknologi informasi (subsistern teknoiogi) diharapkan dapat mengatasi masalah kompetensi dan motivasi (subsistem pengetahuan) pada Pengajar dan Mahasiswa (subsistem manusia). Sebuah skema jalur komunikasi direkomcndasikan. Sebuah intervensi knowledge sharing mengkombinasikan model Organizational Knowledge Creation Nonaka dan Knowledge Strategy lssue Sveiby diimplementasikan menggunakan skcma jalur komunikasi tersebut. Model Basic Organizational Behavior Robbins dan Judge digunakan unmk mclihai dampak intervensi pada tingkat organisaéi, kelompok, dan individu. ......Faculty X of Universitas Y had established “The Research lala of Asia” to be its vision effective since its 2008 administration. The Faculty Dean had lauched an intervention program to push up research productivity, but not all the research groups founded have shown expected performances. Faculty X needs to find ways to trigger research productivity to reach its vision. Using Marquardt’s system-link learning model, Faculty’s problematic symptoms are classified into tive-subsystem slots (Learing, Organization, People, Knowledge, and Technolgy). an IT-based communication management and knowledge sharing intervention are expected to fix academic staff and students‘ issue of competence and motivation. A new commtmication scheme is recommended. A knowledge sharing intervcnsion based on Nonaka and Takeuchi’s Spiral of Organizational Knowledge-Creation and Sveiby’s Knowledge Strategy Issue is designed and to be implemented within that communication scheme. Robbins and Judge’s Basic Organizational Behavior model is utilized to overview the impact the intervention had on organization, group, and individual level.
