Judul: Identifikasi Profil Ingredien serta Kesesuaian Label Kemasan Pangan terhadap Regulasi pada Produk Bakso Daging di Kota Medan
Abstrak: Kebutuhan manusia akan protein seringkali dipenuhi melalui konsumsi daging, yang mana produk olahannya seperti bakso daging sangat populer di Indonesia. Studi ini bertujuan untuk mengidentifikasi profil ingredien dan kesesuaian label kemasan bakso daging di Kota Medan dengan regulasi yang berlaku. Metode penelitian ini melibatkan pengambilan sampel terhadap produk bakso daging yang dijual di berbagai toko ritel di Kota Medan, analisis label kemasan berdasarkan Peraturan BPOM Nomor 31 Tahun 2018 dan Nomor 20 Tahun 2021, serta pengumpulan data ingredien dan bahan tambahan pangan (BTP) yang digunakan. Hasil penelitian menunjukkan bahwa terdapat beberapa penyimpangan dalam pencantuman label, termasuk tidak mencantumkan alamat produsen, tanggal kedaluwarsa, dan informasi nilai gizi. Selain itu, ditemukan bahwa penggunaan bahan tambahan pangan seperti penguat rasa, penstabil, dan pengawet cukup umum pada produk bakso daging. Temuan baru dari penelitian ini menunjukkan adanya variasi dalam penggunaan ingredien dan tingkat kepatuhan terhadap regulasi pelabelan, yang dapat mempengaruhi keamanan dan informasi yang diterima oleh konsumen. Penelitian ini juga menganalisis hubungan kandungan daging dengan nilai gizi dan harga produk bakso daging serta pengelompokan data harga produk bakso daging di Kota Medan. Implikasi dari penelitian ini adalah perlunya peningkatan pengawasan dan edukasi bagi produsen tentang pentingnya kepatuhan terhadap regulasi pelabelan pangan untuk melindungi konsumen., Human protein needs are often met through meat consumption, and processed products such as meatballs are popular in Indonesia. This study aims to identify the ingredient profile and conformity of meatball packaging labels in Medan City with applicable regulations. This research method involves surveying meatball products sold in various retail stores in Medan City, analyzing packaging labels based on BPOM Regulations Number 31 of 2018 and Number 20 of 2021, and collecting data on the ingredients and food additives used. The research results showed several irregularities in labeling, including not including the manufacturer

Judul: Kajian Pemenuhan Regulasi Pelabelan Produk Olahan Daging di Beberapa Pasar di Kota Bogor
Abstrak: Food labelling is important part of food product. Label becomes a simple instrument for consumer to know about quality assurances on meat products. Labelling regulation in Indonesia uses PP 69 Tahun 1999. This reaserch aims to measure how far the implementation of food labelling in the market around of Bogor according to PP Nomor 69 Tahun 1999. The kind of this research is descriptive research and methodology used in this experiment is survey method with purposive sampling. Data processing is using tabulation, diagram, and histogram. Analysis towards to 63 samples of meat product from 12 locations in Bogor shows that 76.86% samples fullfil the technical of food labelling regulation. The data consist of 25,40% samples that display correct label in accordance of the technical regulation of food labelling, 84,13% samples that correct format content, 90.16% that provide minimum information, 90.19% samples that provide other form of information, and then 94,44% samples that fullfil the technical regulation of food labelling on prohibition in displaying of some restricted information.

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.
