Judul: Hubungan Efektivitas Tata Kelola Bank Sampah dengan Kesadaran dan Partisipasi Nasabah dalam Mengelola Sampah
Abstrak: Bank Sampah Asri Mandiri menjadi wadah bagi masyarakat Desa Benteng untuk mengelola sampah. Eksistensi bank sampah tersebut hingga saat ini tak lepas dari tata kelola yang baik. Ketika kesadaran masyarakat telah meningkat, harapannya masyarakat turut berpartisipasi dalam mengelola sampah di Bank Sampah Asri Mandiri. Tujuan dari penelitian adalah menganalisis efektivitas tata kelola bank sampah di Bank Sampah Asri Mandiri, menganalisis kesadaran nasabah dalam mengelola sampah melalui Bank Sampah Asri Mandiri, menganalisis tingkat partisipasi nasabah yang menjadi nasabah di Bank Sampah Asri Mandiri, dan menganalisis hubungan efektivitas tata kelola bank sampah dengan kesadaran dan partisipasi nasabah dalam mengelola sampah. Penelitian ini menggunakan pendekatan kuantitatif dengan didukung oleh data kualitatif. Analisis data kuantitatif menggunakan uji korelasi rank spearman menunjukkan bahwa tingkat efektivitas tata kelola bank sampah memiliki hubungan yang signifikan dengan tingkat kesadaran dan partisipasi nasabah. Hasil uji korelasi menunjukkan semakin tinggi tingkat efektivitas tata kelola bank sampah dapat menentukan tinggi rendahnya tingkat kesadaran nasabah dalam mengelola sampah serta semakin efektif tata kelola bank sampah dapat memengaruhi tingkat partisipasi nasabah dalam mengelola sampah di bank sampah., Asri Mandiri Waste Bank is a forum for the people of Benteng Village to manage waste. The existence of this waste bank to date cannot be separated from good governance. When public awareness has increased, it is hoped that the public will participate in managing waste at the Asri Mandiri Waste Bank. The objectives of the research include analyzing the waste bank management mechanism at the Asri Mandiri Waste Bank, analyzing customer awareness in managing waste through the Asri Mandiri Waste Bank, analyzing the level of customer participation as customers at the Asri Mandiri Waste Bank, and analyzing the relationship between waste bank management and awareness and customer participation in waste management. This research uses a quantitative approach supported by qualitative data. Quantitative data analysis using the Spearman rank correlation test shows that the level of effectiveness of waste bank management has a significant relationship with the level of customer awareness and participation. The correlation test results show that the higher the level of effectiveness of waste bank management can determine the level of customer awareness in managing waste and the more effective waste bank management can influence the level of customer participation in managing waste at the waste bank.

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: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
