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: Penyusunan Dokumen Rencana Hazard Analysis And Critical Control Point (HACCP) Pada Produk Croissant Di PT. Ciptayasa Pangan Mandiri Pulogadung Jakarta
Abstrak: Persaingan antar ndustri pangan semakin meningkat, baik dari dalam maupun luar negeri. Selain itu, perkembangan masyarakat yang dinamis dewasa ini semakin menuntut adanya jaminan keamanan produk pangan. Masyarakat menginginkan pangan tidak hanya enak dan bergizi, namun juga aman dikonsumsi dari segi kimia, fisik, dan biologis. HACCP (Hazard Analysis And Critical Control Point) adalah sistem pengendalian yang dilakukan pada titik-titik kendali kritis dalam setiap tahapan proses untuk menentukan komponen-komponen kondisi atau tahap proses yang harus dikendalikan untuk dapat menjamin bahwa produk yang dihasilkan aman dan memenuhi persyaratan yang ditetapkan. Tujuan kegiatan magang ini adalah untuk meningkatkan pengalaman dan wawasan serta memberi gambaran nyata aplikasi ilmu yang diperoleh selama kuliah, serta menjalin kemitraan antara perguruan tinggi dengan masyarakat industri. Sedangkan tujuan utama dari kegiatan magang adalah menyusun dokumen rencana Hazard Analysis Critical Control Point (HACCP) pada produksi Croissant di PT.Ciptayasa Pangan Mandiri Pulogadung Jakarta.

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.
