Judul: Kajian Kinerja Kader Posyandu di Wilayah Kerja Puskesmas Kecamatan Kebayoran Lama Jakarta Selatan
Abstrak: Penelitian ini bertujuan untuk mempelajari faktor-faktor yang mempengaruhi kinerja kader posyandu di wilayah kerja Puskesmas Kecamatan Kebayoran Lama Jakarta Selatan. Desain penelitian yang digunakan adalah cross sectional dengan memilih 9 posyandu secara acak yang terdiri dari 3 posyandu dari masing-masing strata (madya, purmama, dan mandiri). Jumlah contoh penelitian adalah sebanyak 55 kader yang memenuhi kriteria. Penelitian dilaksanakan pada bulan Mei Juni 2015. Hasil penelitian menunjukkan bahwa sekitar 85% kinerja kader posyandu tergolong baik. Uji korelasi Rank Spearman menunjukkan kinerja kader berhubungan negatif dengan usia (p = 0.082) dan berhubungan positif dengan pengetahuan (p 0.051). Uji Chi-Square = menunjukkan kinerja kader berhubungan dengan status pernikahan (p = 0.039) dan insentif (p = 0.072). Hasil uji regresi menunjukkan bahwa yang mempengaruhi kinerja kader adalah pengetahuan, artinya semakin tinggi pengetahuan semakin baik kinerja kader.

Judul: Factors Related to the Performance of Cadres in Handling Stunting  in Pabuaran Village Bogor Regency
Abstrak: Kader posyandu merupakan ujung tombak utama dalam memasyarakatkan pengetahuan mengenai kesehatan, salah satunya terkait isu stunting. Seorang kader yang baik dapat tercermin dari kinerjanya. Akan tetapi, beberapa penelitian menunjukkan kinerja kader masih rendah. Tujuan penelitian ini adalah (1) mendeskripsikan tingkat kinerja kader posyandu dalam penanganan stunting, dan (2) menganalisis hubungan karakteristik kader, kualitas pelatihan, kompetensi komunikasi interpersonal, dan motivasi dengan kinerja kader dalam penanganan stunting. Penelitian ini menggunakan metode sensus dengan pendekatan kuantitatif dan didukung data kualitatif dengan responden sebanyak 36 orang kader posyandu di Desa Pabuaran, Kabupaten Bogor yang diambil secara sensus. Hasil penelitian menunjukkan tingkat kinerja kader posyandu dalam penanganan stunting berada pada kategori sedang. Penelitian ini juga menunjukkan bahwa pekerjaan, lama menjadi kader, tingkat pengetahuan, intensitas pelatihan, kompetensi komunikasi interpersonal, dan motivasi ekstrinsik berhubungan nyata dengan kinerja kader posyandu dalam penanganan stunting., Posyandu cadres are the main spearhead in disseminating knowledge about health, one of them is the issue of stunting. A good cadre can be reflected from their performance. However, several studies have shown that the performance of cadres is still low. The purpose of this study are to (1) describe the performance level of posyandu cadres in handling stunting, and (2) analyze the relationship between cadre characteristics, training, interpersonal communication competence, and motivation with cadres' performance in handling stunting. This study used a census method with a quantitative approach and supported by qualitative data with 36 posyandu cadres in Pabuaran Village, Bogor Regency who were taken by census. The results of the study show that the performance level of posyandu cadres in handling stunting is in the moderate category. This study also shows that job, years of service, level of knowledge, training intensity, interpersonal communication competence, and extrinsic motivation are significantly related to the performance of posyandu cadres in handling stunting.

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.
