Judul: Manfaat partisipasi masyarakat  dalam program pengelolaan sampah
Abstrak: Adi Chandra Berampu. Manfaat Partisipasi Masyarakat dalam Program Pengelolaan Sampah. Di bawah bimbingan IVANOVICH AGUSTA. Keberadaan perusahaan dalam suatu wilayah masyarakat seharusnya dapat membawa manfaat bagi masyarakat itu sendiri baik dalam aspek sosial, ekonomi, dan lingkungan. Untuk mewujudkan harapan tersebut maka disusun program-program CSR dengan memperhatikan partisipasi masyarakat dan pemangku kepentingan lainnya, sebab partisipasi merupakan salah satu prinsip pengembangan masyarakat yang paling penting. Diduga terdapat faktor internal (karakteristik individu) yang berhubungan dengan tingkat partisipasi. Variabel faktor internal yang diteliti adalah tingkat umur, tingkat pendidikan, lama tinggal, dan tingkat pendapatan. Hasil penelitian kemudian menunjukkan bahwa tidak terdapat hubungan antara karakteristik individu dengan tingkat partisipasi masyarakat. Tingkat partisipasi masyarakat diduga berhubungan dengan tingkat manfaat program yang dapat dirasakan. Variabel tingkat manfaat yang diteliti antara lain tingkat pengetahuan, tingkat keterampilan, tingkat kebersihan lingkungan, dan tingkat peluang ekonomi. Hasil penelitian menunjukkan bahwa terdapat hubungan antara tingkat partisipasi dengan tingkat manfaat program yang diperoleh masyarakat., ADI CHANDRA BERAMPU. Benefits of Public Participation in Waste Management Program. Suvervised by IVANOVICH AGUSTA. The existence of the company in a public area should be able to bring benefits to society itself, as in the social, economic, and environmental. To realize these expectations then CSR programs are implemented by taking into account the participation of the community and other stakeholders, because participation is one of the the most important of community development principles. There are internal factors that considered relates to the level of participation. Variables of internal factor (individual characteristics) are age level, education level, length of stay, and income level. The results of the research showed that there is no relationship between the individual characteristics to the level of community participation. The level of community participation considered relates to the level of program‟s benefits that can be felt. Variables of program utilization such as the level knowledge level, skill level, environmental cleanliness level, and economic opportunities level. The results of the research showed that there is a relationship between the level of participation and the level of program‟s benefits that community receive.

Judul: Relation of Participation Level with Management  Effectiveness in the Waste Bank Program (Case: Bersih Indah dan Cantik Waste  Bank, Pasar Kemis District, Tangerang Regency, Provinsi Banten Province)
Abstrak: Bank sampah merupakan suatu sistem pengelolaan sampah kering secara kolektif yang dilakukan untuk mendorong masyarakat agar berpartisipasi secara aktif dalam pengelolaan sampah yang ada di lingkungan mereka. Pengelolaan sampah membutuhkan peran serta masyarakat baik dalam tahap pengambilan keputusan, tahap pelaksanaan, tahap menikmati hasil, dan tahap evaluasi. Tujuan penelitian ini adalah untuk menganalisis tingkat partisipasi dalam pengelolaan sampah dan faktor-faktor yang memengaruhinya, efektivitas pengelolaan sampah, serta hubungan tingkat partisipasi dengan efektivitas pengelolaan dalam program bank sampah. Metode yang digunakan dalam penelitian ini adalah metode survei dengan pendekatan kuantitatif yang didukung oleh data kualitatif melalui wawancara mendalam dan studi literatur. Hasil penelitian menunjukkan tingkat partisipasi berada pada kategori tinggi kecuali indikator tahap menikmati hasil dan evaluasi, sedangkan efektivitas pengelolaan sampah berada pada kategori sedang kecuali aspek kelembagaan. Terdapat hubungan ketersediaan sarana dan prasarana, ajakan teman atau anggota bank sampah dan tingkat dukungan keluarga dengan tingkat partisipasi. Terdapat hubungan tidak nyata pada indikator usia, tingkat pendidikan, dan tingkat pengetahuan, serta hubungan yang tidak nyata dan negatif pada indikator besar pendapatan dengan tingkat partisipasi. Terdapat hubungan nyata antara tingkat partisipasi dengan efektivitas pengelolaan sampah pada aspek kelembagaan, dan regulasi. Terdapat hubungan yang tidak nyata pada indikator aspek pembiayaan dan teknik operasional pengelolaan sampah., The waste bank is a collective dry waste management system which is conducted to encourage community to be active in managing the waste in their environment. Waste management involve community participation in the decision making stage, the implementation stage, the benefits stage, and the evaluation stage. The purpose of this research is to analyze the level of community participation in the waste management and the factors that influence it, the effectiveness of waste management, and also the relationship between the level of community participation and the effectiveness of management in the waste bank program. The method used in this research is a survey method with a quantitative approach supported by qualitative data through in-depth interviews and literature studies. The result showed that the level of community participation was in the high category, except for the indicators of benefit stage and evaluation stage. Meanwhile, the effectiveness of waste management is in the medium category, except for the institutional aspects. There is a relationship between the availability of facilities and infrastructure, the invitation of friends of waste bank members, and the level of family support with the level of community participation. There is also unsignificant relationship between the indicators of age, level of education, and the level of knowledge, as well as the unsignificant and negative relationship on the indicators the amount of income with the level of community participation. There is a relationship between the level of community participation with the effectiveness of the waste management in the aspect of institutional, and regulatory aspects. There is a unsignificant relationship on the indicators of the financing aspects and the operational techniques of waste management.

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.
