Judul: Correlation between Fruits Vegetables, Protein Consumption  and Household Food Diversity for KRPL Recipient in Gresik Regency
Abstrak: Kawasan Rumah Pangan Lestari (KRPL) memiliki tujuan untuk mengoptimalkan pekarangan rumah dalam memenuhi pangan dan gizi serta diversifikasi. Tujuan penelitian ini adalah menganalisis dampak KRPL terhadap kebiasaan konsumsi buah, sayur, dan protein hewani serta keragaman pangan rumah tangga di Kabupaten Gresik. Desain penelitian yang digunakan adalah comparative study dengan pendekatan cross sectional. Penelitian ini bertujuan untuk membandingkan frekuensi dan keragaman pangan antara 2 kelompok subjek yang dilakukan secara simultan pada satu waktu. Penelitian ini menggunakan data primer dengan jumlah subjek sebanyak 60 terdiri dari 30 rumah tangga penerima dan 30 rumah tangga non-penerima program KRPL yang dipilih secara purposive. Data frekuensi konsumsi dan kebiasaan konsumsi rumah tangga didapatkan dari wawancara menggunakan kuesioner. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan nyata keragaman pangan pada kedua kelompok subjek (p>0.05). Frekuensi konsumsi buah, sayur, dan protein hewani tidak berbeda nyata pada kedua kelompok subjek (p>0.05), serta tidak terdapat hubungan antara frekuensi buah, sayur, dan protein hewani dengan keragaman pangan (p>0.05)., The purpose of Kawasan Rumah Pangan Lestari (KRPL) is to optimize the yards to provide food and nutrition also diversification. The study evaluates the KRPL impact on fruits, vegetables, animal protein consumption, and the household food diversity in Gresik Regency. The research design was a comparative study with a cross-sectional approach. The study was intended to compare the frequency and household food diversity between both of the subject groups simultaneously in a single moment. The study uses primary data with 60 subjects, comprised of 30 household that receive and 30 household non-receive KRPL program. Data on food frequency and household dietary habits is obtained from interviews using questionnaires. The result shows that there’s no difference in food dietary diversity score (p>0.05) and frequency consumption of fruits, vegetables, animal proteins in both of the subject groups (p>0.05), and there was no significant correlation between frequency of fruits, vege

Judul: The Correlation between Individual Characteristics and Individual’s Roles in Group with Sustainability of Women’s Farmers Group’s (WFG) Activities in the KRPL’s Program
Abstrak: Kawasan Pangan Rumah Lestari (KRPL) merupakan program yang diluncurkan oleh Kementerian Pertanian untuk menjamin ketahanan pangan pada level rumah tangga dan komunitas. Selaras dengan Undang-Undang Nomor 18/2018 tentang Pangan menyebutkan untuk mengatasi persoalan ketersediaan pangan diperlukan berbagai upaya salah satunya dengan memanfaatkan, melestarikan dan mengembangkan lahan secara produktif. Tujuan dari penelitian ini ialah menganalisis hubungan antara karakteristik individu dan peran kelompok dengan kebelanjutan aktivitas KWT di Program KRPL. Penelitian dilakukan di Kelurahan Pamulang Barat, Kota Tangerang Selatan. Responden penelitian ini berjumlah 32 orang ditentukan dengan metode sensus. Analisis data dilakukan secara deskriptif dan uji korelasi Rank Spearman. Hasil penelitian menunjukkan bahwa terdapat hubungan yang nyata yaitu antara karakteristik individu berupa umur dan tujuan bergabung dengan peran kelompok, dan peran kelompok berhubungan nyata dengan keberlanjutan aktivitas KWT di Program KRPL. Peran individu dalam kelompok yang tinggi membantu keberlanjutan KRPL dalam mewujudkan kemandirian dan diversifikasi pangan berbasis sumber daya lokal., Sustainable Reserve Food Garden Program (SRFGP) is a program launched by the Ministry of Agriculture to ensure food security at the household and community level. According to Law No. 18/2018 about Food mentions that the issue of food availability requires various efforts, one of them is by utilizing, preserving and developing land productively. The purpose of this study is to analyze the relationship between individual characteristics and the role of the group with the continuity of KWT activities in the KRPL Program.The research was conducted in Pamulang Barat Village, South Tangerang City. The respondents of this study numbered 32 people determined by census method. Data analysis was conducted descriptively and correlation test Rank Spearman. The results showed that there is a real relationship between the characteristics of individuals in the form of age and the purpose of joining the role of the group, and the role of the group is in real contact with the sustainability of KWT activities in the KRPL Program.The high role of the individual’s of group helps krpl sustainability in realizing self-reliance and diversification of food based on local resources.

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.
