Judul: Assistance for Improvement and Implementation of Good Manufacturing Practices in Frozen Karage Production Process at XYZ MSEs Bogor
Abstrak: Keamanan pangan menjadi hal yang sangat krusial untuk diperhatikan dalam melindungi konsumen dari pangan yang tidak aman. Setiap konsumen berhak atas pemenuhan pangan yang aman dan bermutu. Penjaminan pangan dapat dilakukan oleh pelaku usaha dengan menerapkan praktik keamanan pangan yang benar. UMK XYZ dengan produk ayam karage beku belum menerapkan Cara Produksi Pangan Olahan yang Baik (CPPOB). Penelitian ini bertujuan menganalisis kesenjangan penerapan CPPOB, melakukan pendampingan dan perbaikan sarana produksi, penyusunan dokumen CPPOB, dan pendaftaran sertifikasi CPPOB. Pengambilan data dilakukan dengan mengidentifikasi ketidaksesuaian kritis, mayor, dan minor menggunakan checklist pada SK BPOM No. HK.02.02.1.2.01.22.63 Tahun 2022. Penerapan CPPOB di UMK XYZ sebelum pendampingan mendapatkan rating D (sangat kurang) dengan nilai kesesuaian 46,23% dan setelah pendampingan masih terdapat ketidaksesuaian hanya pada klausul lingkungan, air, dan ventilasi sehingga rating meningkat menjadi A (sangat baik) dengan nilai kesesuaian 95,28%. Proses sertifikasi CPPOB dilakukan dengan mengunggah dokumen persyaratan dan sertifikat CPPOB UMK XYZ telah diterbitkan BPOM., Food safety is a crucial factor to consider when protecting consumers from unsafe food. Every consumer has the right to fulfill the safety and quality of food. Food assurance can be carried out by business actors by implementing appropriate food safety practices. XYZ MSEs, which produce frozen karage chicken, have not implemented GMP. This research analyzed the gap in GMP implementation, assisted and improved production facilities, prepared GMP documents, and registered for GMP certification. Data were collected by identifying critical, major, and minor non-conformities using the checklist in BPOM Regulation No. HK.02.02.1.2.01.22.63 of 2022. The implementation of GMP in XYZ MSEs before assistance received a D (very poor) rating with a conformity value of 46,23% and after assistance there were still non-conformities only in the environment, water, and ventilation clauses so that rating increased to A (very good) with a conformity value of 95,28%. The GMP certification is carried out by uploading the required documents and the GMP certificate for XYZ MSEs has been issued by BPOM.

Judul: Evaluation and Assistance in Improvement as well as Issuance of GMP Implementation License in MSMEs XYZ
Abstrak: Usaha Mikro, Kecil, dan Menengah (UMKM) XYZ merupakan salah satu perusahaan di Kota Depok yang memproduksi pangan olahan frozen food, salah satunya adalah bakso daging. Di sisi lain, UMKM XYZ belum sepenuhnya menerapkan Cara Produksi Pangan Olahan yang Baik (CPPOB) dalam proses produksinya. Perusahaan yang menerapkan CPPOB akan menghasilkan produk pangan yang aman untuk dikonsumsi. Penelitian ini bertujuan mengevaluasi dan memperbaiki penerapan CPPOB di UMKM XYZ serta membantu perusahaan dalam penerbitan izin penerapan CPPOB. Metode penelitian yang digunakan yaitu analisis kesenjangan penerapan CPPOB dengan formulir checklist penilaian penerapan CPPOB, perbaikan penerapan CPPOB, dan penyusunan dokumen untuk penerbitan izin penerapan CPPOB. Evaluasi penerapan CPPOB UMKM XYZ sebelum perbaikan menunjukkan rating D (sangat kurang). Penyusunan dokumen sebagai syarat pendaftaran izin penerapan CPPOB telah dilakukan. Penerbitan izin penerapan CPPOB dilakukan melalui proses pendaftaran akun, pengajuan permohonan, dan proses penilaian oleh Badan Pengawas Obat dan Makanan (BPOM). Terdapat perbedaan hasil setelah dilakukan perbaikan penerapan CPPOB menjadi rating B (baik). Pendampingan telah dilaksanakan hingga UMKM XYZ dinilai memenuhi persyaratan dan izin penerapan CPPOB UMKM XYZ telah diterbitkan oleh BPOM., The XYZ Micro, Small, and Medium Enterprises (MSMEs) is one of the companies in Depok City that produces processed frozen foods, one of which is meatball. However, XYZ MSMEs have not fully implemented Good Manufacturing Practices (GMP) in their production processes. Companies that implement GMP will produce food products that are safe for consumption. This study aims to evaluate and improve the implementation of GMP in XYZ MSMEs and assist the company in obtaining GMP Implementation Permit. The research methods used include the analysis of the gap in GMP implementation using a GMP implementation checklist, GMP implementation improvement, and document preparation for GMP Implementation Permit issuance. The evaluation of GMP implementation in XYZ MSMEs before improvement showed a rating of D (very poor). Document preparation as a requirement for GMP implementation permit registration has been completed. The issuance of GMP Implementation Permit is carried out through the account registration process, submission of application, and assessment process by the National Agency of Drug and Food Control (BPOM). There was a difference in results after the GMP implementation improvement, with a rating of B (good). Assistance has been provided until XYZ MSMEs are deemed to meet the requirements, and the GMP Implementation Permit for XYZ MSMEs has been issued by BPOM.

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.
