Judul: Implementasi Sistem Jaminan Halal dan Standar Nasional Indonesia Sepatu Kulit di Pabrik Sepatu Kulit Catenzo.
Abstrak: Sepatu kulit merupakan salah satu barang gunaan yang dipasarkan di Indonesia dan diharapkan memenuhi Standar Nasional Indonesia (SNI) sepatu kulit nomor 2942.1-2:2009 sehingga dapat meningkatkan jaminan mutu dan kepercayaan masyarakat terhadap produk sepatu kulit. Selain pemenuhan SNI, Sistem Jaminan Halal (SJH) saat ini perlu diterapkan untuk barang gunaan sepatu kulit untuk menunjukkan status kehalalan produk serta pemenuhan peraturan Undang-Undang Republik Indonesia Nomor 33 Tahun 2014. Pabrik sepatu kulit Catenzo telah memproduksi dan memasarkan sepatu kulit sejak tahun 2007 namun produk yang dihasilkan belum pernah diuji sepenuhnya terhadap SNI sepatu kulit dan persyaratan sertifikasi halal HAS 23000. Penelitian ini bertujuan untuk mengembangkan manual SJH dan uji coba penerapannya di pabrik sepatu kulit Catenzo. Manual SJH yang disusun berisi kebijakan halal, tim manajemen halal dan prosedur implementasi, evaluasi serta perbaikan sistem. Manual SJH disusun sesuai dengan proses bisnis dan kondisi nyata di pabrik sepatu kulit Catenzo. Hasil penelitian menunjukkan bahwa manual SJH dapat diimplementasikan kecuali pelatihan eksternal dan pengujian ketahanan kikis Grasselli.

Judul: Desain Manual Sistem Jaminan Halal untuk Usaha Kecil dan Implementasinya di Koperasi Sapta Fateta-IPB
Abstrak: SJH manual is halal assurance system plan implementation document for corporates or stakeholders. It describes all activities to meet eleven criteria which have been written in Halal Assurance System 23 000 (HAS 23 000). The objection of this research is to result SJH manual which is not difficult to be implemented in micro business unit and to evaluate SJH manual implementation in Sapta Cooperative FATETA-IPB. This research started through chain of actions from identifying business process, gathering data needed, composing SJH manual, implementing SJH manual and admission process for Sapta Cooperative FATETA-IPB halal assurance system certification. Composing SJH manual was begun by identifying business process, material and production facility condition in all micro enterprise unit in Sapta Cooperative FATETA-IPB. Based on those information, SJH manual was composed in a simple form to implement. SJH manual consists of halal policy statement, halal management team, operational procedure of implementation and evaluation of system implementation. It was then able to be used as halal certification registration. Implementation simulation which was held in Sapta Cooperative FATETA-IPB showed that there were several obstacles needed to be solved before advancing to the halal certification process in Majelis Ulama Indonesia (MUI).

Judul: Pengaruh Infeksi Virus pada Phytoplankton dan Racun yang Dihasilkan Phytoplankton dalam Model Interaksi Phytoplankton-Zooplankton
Abstrak: Interaction of phytoplankton and zooplankton can be considered as a prey-predator interaction, where phytoplankton as prey and zooplankton as predator. This interaction is modeled into mathematical equations that was investigated by Gakkhar & Negi (2005). This model studied the effect of viral infection on phytoplanktons and the toxin produced by phytoplankton. In this model, phytoplanktons are divided into two groups, suspectible phytoplankton and infected phytoplankton. Hopf bifurcation describes the stability changes of population. The Hopf bifurcation occurs when the rate of viral infection and the toxin quantity produced by phytoplakton were changed. Both phytoplankton and zooplankton populations stable when the infection rate and toxin quantity are low. If the viral infection rate and toxin quantity increase then phytoplankton and zooplankton populations became unstable. If the viral infection rate and the toxin quantity relatively high then the zooplankton population would lead to extinction
