Judul: Strategy to Increase the Number of Halal Self Declare Certification in Indonesia
Abstrak: Sertifikasi halal Self Declare adalah skema sertifikasi yang dibuat dengan tujuan mempermudah usaha mikro dan kecil (UMK) dalam mendapatkan sertifikasi halal. Faktanya, jumlah sertifikasi halal Self Declare masih sedikit dibanding dengan jenis sertifikasi halal lain dan masih sangat jauh dibandingkan dengan jumlah UMK di Indonesia. Tujuan dari penelitian ini adalah untuk mengidentifikasi kekuatan, kelemahan, peluang, ancaman, dan merumuskan strategi peningkatan jumlah sertifikasi halal Self Declare di Indonesia. Metode analisis yang digunakan adalah Analytical Network Process (ANP) dengan pendekatan strength, weakness, opportunities and threats (SWOT). Hasil penelitian ini menunjukkan bahwa aspek kelemahan menjadi aspek prioritas dalam pertimbangan perumusan strategi peningkatan jumlah sertifikasi halal Self Declare. Aspek kekuatan yang paling prioritas adalah tersedianya regulasi kewajiban sertifikasi halal. Aspek kelemahan yang paling dominan adalah persebaran informasi yang belum merata. Aspek peluang yang paling prioritas adalah banyaknya pelaku UMK di Indonesia. Aspek ancaman yang paling dominan adalah pemahaman masyarakat dan literasi yang masih belum merata. Strategi yang paling prioritas untuk diterapkan adalah pengoptimalan sistem online BPJPH., The Self Declare halal certification is a certification scheme designed with the aim of facilitating Micro and Small Enterprises (MSEs) in obtaining halal certification. In fact, the number of self-declared halal certifications in Indonesia is still relatively low compared to the other type of halal certification and significantly lower compared to the total number of MSEs in Indonesia. The purpose of this research is to identify the strengths, weaknesses, opportunities, and threats related to self-declared halal certification and to formulate a strategy to maximize the potential. The analysis method used in this study is the Analytical Network Process (ANP) with a Strength, Weakness, Opportunities, and Threats (SWOT) approach. The study found that weaknesses should be the primary focus when developing strategies to increase self declared halal certification, while the most critical strength is the existence of mandatory regulations for halal certification. The most significant weakness is the uneven distribution of information, and the most significant opportunity is the large number of MSEs in Indonesia. The most significant threat is the uneven level of community understanding and literacy. The most effective strategy to increase self declared halal certification is optimizing the BPJPH online system.

Judul: Niat dan Perilaku Pelaku Usaha Mikro dan Kecil
(UMK) Terhadap Halal Self Declare (Studi Kasus: Halal Science Center IPB).
Abstrak: Berdasarkan Peraturan Pemerintah nomor 39 tahun 2021, halal self declare adalah skema pengajuan sertifikasi halal bagi UMK dengan produk berbahan baku bukan daging. Penelitian ini bertujuan untuk menganalisis karakteristik dan faktor-faktor yang memengaruhi niat dan perilaku pelaku UMK terhadap halal Self Declare. Model acuan dalam penelitian ini menggunakan theory of planned behavior (TPB) yang telah dimodifikasi. Penentuan responden dalam penelitian ini menggunakan teknik purposive sampling. Populasi responden merupakan semua pelaku UMK yang sudah memiliki sertifikat halal melalui Halal Science Center (HSC) IPB. Pengumpulan data dari responden menggunakan kuesioner yang disebarkan secara langsung dan dianalisis menggunakan analisis deskriptif dan SEM-PLS. Hasil penelitian menunjukkan bahwa variabel attitude, kesadaran halal, dan religiusitas berpengaruh positif dan signifikan terhadap niat halal self declare. Variabel yang berpengaruh positif dan signifikan terhadap perilaku self declare adalah perceived behavioral control dan niat halal self declare., Based on Government Regulations number 39 of 2021, halal self declare is a scheme for applying a halal certification for MSEs with products made from non-meat raw materials. This research aims to analyze the characteristics and factors which influence the intention and behavior of SMEs toward halal self declare. A modification reference model from the theory of planned behavior is applied in this research. In this study, the respondents were determined using a purposive sampling technique. The respondent population were all MSE actors who already had halal certificates through Halal Science Center (HSC) IPB. Data collection from respondents using questionnaires distributed directly and analyzed using descriptive analysis and SEM-PLS. The results showed that the variables of attitude, halal awareness, and religiosity had a positive and significant effect on halal self declare intentions. The variables that have a positive and significant effect on halal self declare behavior are perceived behavioral control and halal self declare intention.

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.
