Judul: Efektivitas Pengelolaan Zakat di BAZNAS Kota Bogor dengan Pendekatan Indeks Implementasi ZCP
Abstrak: Kemiskinan merupakan permasalahan yang dihadapi oleh pemerintah Indonesia. Permasalahan tersebut dapat diatasi dengan melakukan redistribusi. Salah satu instrumen penting dalam sistem redistribusi yaitu zakat. BAZNAS Kota Bogor menjadi lembaga amil yang menangani pengelolaan zakat di Kota Bogor. Dengan penduduk muslim yang mencapai 969.343 jiwa, secara implisit bahwa Kota Bogor memiliki potensi zakat yang besar. Namun, pengelolaan zakat belum berjalan dengan optimal karena masih besarnya gap antara potensi dan realisasinya. Penelitian ini bertujuan untuk menghitung nilai indeks implementasi ZCP di BAZNAS Kota Bogor dan untuk menganalisis perolehan nilai indeks dimensi yang tertinggi dan terendah guna meningkatkan performa pengelolaan zakat. Penelitian ini diambil dengan metode studi kasus (case study), melalui wawancara terstruktur satu per satu narasumber dengan menggunakan kuesioner dan in-dept interview. Alat analisis yang digunakan pada penelitian ini adalah Indeks Implementasi ZCP dengan metode penghitungan yang dinamakan Multi-Stage Weighted Index. Hasil penelitian menunjukkan bahwa pengelolaan zakat di BAZNAS Kota Bogor sudah sangat baik dengan nilai Indeks Implementasi ZCP sebesar 0.82 yang berarti BAZNAS Kota Bogor menjadi model percontohan organisasi yang telah mengimplementasikan indikator ZCP., The Indonesian government is frequently confronted with poverty. Redistribution is a way to solve these challenges. Zakat is a key tool in the system of redistribution. Bogor City BAZNAS is a Muslim-run organization that manages zakat in Bogor. Bogor City has a big zakat potential due to its Muslim population of 969,343 individuals. The management of zakat, on the other hand, has not ran smoothly because there is still a significant gap between its promise and its actualization. The goal of this research is to calculate the ZCP implementation index value at BAZNAS Bogor City and assess the acquisition of the highest and lowest dimensional index values in order to improve zakat management performance. This study was conducted utilizing a case study method, which included one-on-one structured interviews with respondents using questionnaires and in-depth interviews. The ZCP Implementation Index was employed in this study, with the Multi-Stage Weighted Index as the computation technique. The results showed that the management of zakat in BAZNAS Bogor City was very good with a ZCP Implementation Index value of 0.82, which means that BAZNAS Bogor City has become a pilot model for organizations that have implemented ZCP indicators.

Judul: EFEKTIVITAS PENGELOLAAN ZAKAT DENGAN PENDEKATAN INDEKS IMPLEMENTASI ZAKAT CORE PRINCIPLE (STUDI KASUS: BAZNAS KOTA SUKABUMI)
Abstrak: ERMIYANTI. Efektivitas Pengelolaan Zakat Dengan Pendekatan Indeks Implementasi Zakat Core Principle (Studi Kasus: BAZNAS Kota Sukabumi). Dibimbing oleh IRFAN SYAUQI BEIK. Organisasi Pengelolaan Zakat (OPZ) memiliki peran penting dalam pengelolaan zakat sehingga diperlukan perhatian khusus untuk mengevaluasi kinerjanya. Kota Sukabumi memiliki potensi zakat sebesar Rp148,46 miliar. Namun, terdapat gap antara realisasi dengan potensi yang dimiliki. Penelitian ini bertujuan untuk menganalisis efektivitas pengelolaan zakat berdasarkan indeks implementasi ZCP di BAZNAS Kota Sukabumi dan untuk memformulasikan rekomendasi strategi penguatan kinerja BAZNAS Kota Sukabumi. Metode yang digunakan dalam penelitian ini adalah Multi-Stage Weighted Indeks dan analisis tiga tahap formulasi strategi. Hasil penelitian menunjukan bahwa BAZNAS Kota Sukabumi memiliki skor Indeks Implementasi ZCP sebesar 0,81. Hal tersebut menjadikan BAZNAS Kota Sukabumi termasuk ke dalam kategori sangat baik, artinya BAZNAS Kota Sukabumi dijadikan sebagai model/contoh dalam pengimplementasian indikator ZCP. Selain itu, dihasilkan lima alternatif strategi dengan prioritas strategi, yaitu penguatan kerjasama dalam bentuk aliansi untuk mempermudah perusahaan atau organisasi untuk mengelola zakat., ERMIYANTI. The Effectiveness of Zakat Management with the ZCP Implementation Index Approach (Case study: BAZNAS of Sukabumi City). Supervised by IRFAN SYAUQI BEIK. The Zakat Management Organization (OPZ) plays a crucial role in zakat management, necessitating special attention to evaluate its performance. Sukabumi City has a zakat potential of Rp148.46 billion. However, there is a gap between the realized amount and its potential. This research aims to analyze the effectiveness of zakat management based on the ZCP implementation index at BAZNAS Sukabumi City and formulate recommendations for enhancing BAZNAS Sukabumi City's performance. The method used in this research is the Multi-Stage Weighted Index and a three-stage analysis for strategy formulation. The research results show that BAZNAS of Sukabumi city has an Index of ZCP Implementation score of 0.81. This places BAZNAS of Sukabumi city in the category of very good, indicating that it serves as a model organization that has implemented ZCP indicators. In addition, five alternative strategies are generated, with the priority strategy being the strengthening of cooperation in the form of alliances to facilitate companies or organizations in managing zakat.

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.
