Judul: Kaji Ulang Rencana HACCP pada Proses Pembuatan Produk Kakao di PT. Bumitangerang Mesindotama – Tangerang
Abstrak: PT. Bumitangerang Mesindotama (BT Cocoa) has established food safety management comprehensively to assure the quality and safety of cocoa products such as cocoa liquor, cocoa cake, cocoa powder, and cocoa butter. One important component of food safety management system is the implementation of HACCP (Hazard Analysis Critical Control Point) plan. Analysis of hazard potentials needs to be reviewed according to factory actual conditions, such as new machines addition, new scientific hazard potentials research, and consumer complaints. The review is done systematically following the twelve logical steps or seven principles of HACCP according to Codex Alimentarius Commission. The review results suggest that there are 11 CCP and 11 OPrP comes from existing machines, new machines, and new CCP from existing machines.

Judul: Kaji Ulang Rencana HACCP pada Produksi Bumbu Penyedap Granulated Bouillon di Pabrik Citarasa Indonesia Karawang.
Abstrak: Pabrik Citarasa Indonesia telah melaksanakan sistem manajemen keamanan pangan secara komprehensif dalam menjaga kualitas dan keamanan produk bumbu penyedap Granulated Bouillon. Komponen penting dalam sistem manajemen keamanan pangan ada di dalam rencana HACCP. Analisis mengenai bahayabahaya pada setiap proses produksi perlu dikaji ulang agar dokumen HACCP selalu sesuai dengan kondisi terkini di lapangan, adanya bukti ilmiah mutakhir mengenai tingkat bahaya suatu proses, dan beberapa keluhan konsumen. Metode yang digunakan dalam kajian ini mengikuti dua belas langkah logis atau tujuh prinsip HACCP sesuai acuan Codex Alimentarius Commission. Sebelum dilakukan pengkajian terhadap CCP dan OPRP, perusahaan telah menetapkan 1 CCP yaitu pada mesin Metal Detector dan 4 OPRP diantaranya pada mesin Sifting 1, Sifting 2, Magnetic Trap dan pada bahan pasta bawang putih pada proses produksi Granulated Bouillon. Kajian ulang HACCP yang telah dilaksanakan menghasilkan 1 CCP dan 3 OPRP yang diperoleh berdasarkan observasi lapang dan studi literatur

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
