Studi kasus pada penelitian ini adalah kopi Cisentar yang berasal dari Desa Mekarjaya, Kabupaten Bogor. Teknik pengambilan data pada penelitian ini menggunakan metode kualitatif dengan penentuan responden menggunakan metode purposive sampling. Data yang terkumpul diolah menggunakan analisis fishbone diagram, analisis VRIO, dan analisis rantai nilai. Hasil penelitian menunjukkan bahwa kopi Cisentar memiliki tiga akar permasalahan utama (pasar, pembiayaan, dan pemberdayaan), kopi Cisentar memiliki keunggulan internal berkelanjutan, dan terdapat tiga program peningkatan rantai nilai kopi Cisentar., Coffee production by smallholder plantations must be balanced with sufficient farmer knowledge and technology. Therefore, the quality and productivity of Indonesian coffee is relatively low compared to other countries.

The case study in this study is Cisentar coffee originating from Mekarjaya Village, Bogor Regency. Data collection techniques in this study used qualitative methods by determining respondents using purposive sampling methods. The collected data were processed using fishbone diagram analysis, VRIO, and value chain analysis. The results showed that Cisentar coffee has three main root problems (market, financing, and empowerment), Cisentar coffee has sustainable internal advantages, and there are three programs to improve the Cisentar coffee value chain.

Judul: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
