Judul: The Influence of Waste Bank on Customers’ Income and Participation in Environmental Cleanliness (Case Study: The Unit Waste Bank of Jatijajar Village)
Abstrak: Bank sampah dibentuk untuk membantu mengurangi permasalahan sampah dan kebersihan lingkungan dengan mengubah sampah agar memiliki nilai ekonomis sehingga dapat menjadi tambahan pendapatan bagi rumah tangga. Tujuan dari penelitian ini yaitu untuk menganalisis pengaruh bank sampah terhadap tingkat pendapatan dan tingkat partisipasi nasabah dalam kebersihan lingkungan yang dilihat dari perbedaan nasabah dan non nasabah bank sampah. Penelitian ini menggunakan metode penelitian mix method dengan menggabungkan metode kualitatif dan kuantitatif secara bertahap. Data kualitatif berasal dari observasi dan wawancara mendalam dengan informan sedangkan data kuantitatif berasal dari metode survei menggunakan kuesioner kepada 60 responden dengan proporsi 30 nasabah bank sampah sebagai responden utama dan 30 non nasabah bank sampah sebagai responden kontrol. Data kuantitatif diolah dengan Paired Sample T-Test dan Mann-Whitney. Hasil penelitian menunjukkan terdapat perbedaan yang signifikan antara nasabah dan non nasabah bank sampah tapi tidak sebagai pengaruh dari bank sampah dengan tingkat pendapatan nasabah, namun perbedaan tersebut sebagai pengaruh dari bank sampah dengan tingkat partisipasi nasabah dalam kebersihan lingkungan., Waste banks are formed to help reduce waste and environmental cleanliness problems by converting waste to have economic value so that it can be an additional income for households. The purpose of this study is to analyze the influence of waste banks on customers' income level and participation level in environmental cleanliness as seen from the differences between customers and non-customers of waste banks. This research uses a mixed method research method by combining qualitative and quantitative methods in stages. Qualitative data is derived from observations and in-depth interviews with informants while quantitative data comes from survey methods using questionnaires to 60 respondents with a proportion of 30 waste bank customers as primary respondents and 30 non-customers of the waste bank as controlling respondents. The results showed that there is a significant difference between waste bank customers and non-customers but not as an influence of the waste bank on the level of customer income, but the difference as an influence of the waste bank with the level of customer participation in environmental cleanliness.

Judul: Factors Associated with Environmental, Economic  and Social Benefits of Waste Banks.
Abstrak: Bank sampah dipandang dapat menjadi salah satu solusi atas masalah sampah di Indonesia. Penelitian ini menjelaskan apakah karakteristik nasabah, tingkat kinerja pengurus dan tingkat partisipasi masyarakat merupakan faktor-faktor yang memiliki hubungan dengan manfaat yang dihasilkan bank sampah. Penelitian ini dilakukan di RW 01, Kelurahan Babakan, Kota Bogor dengan tujuan untuk menganalisis karakteristik nasabah, tingkat kinerja pengurus, tingkat partisipasi masyarakat dan manfaat yang dihasilkan bank sampah. Penelitian ini menggunakan metode campuran (mixed method). Metode kuantitatif menggunakan kuesioner sebagai alat pengumpul data dari 35 responden dan didukung dengan data kualitatif melalui observasi terlibat dan wawancara mendalam dengan informan kunci. Analisis data kuantitatif dengan menggunakan uji korelasi rank spearman mengindikasikan bahwa indikator tingkat pendidikan memiliki hubungan yang signifikan dengan indikator tahap perencanaan pada tingkat partisipasi masyarakat. Hasil uji korelasi juga menunjukkan bahwa tingkat kinerja pengurus memiliki hubungan yang signifikan dengan tingkat partisipasi masyarakat. Selain itu, tingkat partisipasi masyarakat memiliki hubungan yang signifikan dengan manfaat bank sampah, Waste banks are seen as a solution to the waste problem in Indonesia. This research explains whether customer characteristics, level of management performance and level of community participation are factors that are related to the benefits generated by waste banks. This research was conducted in RW 01, Babakan Village, Bogor City. This research uses mixed methods. The quantitative method uses a questionnaire as a data collection tool from 35 respondents. Quantitative data analysis indicates that the education level has a significant relationship with the planning stage on the community participation level.

Judul: Sintesis Flavon dari Fenol dan Benzoil Klorida
Abstrak: Flavone is a class of flavonoid, commonly found in plants with wide bioactivity spectrum. A widely used flavone synthesis route is through acidcatalyzed oxidative cyclization of β-diketone. In this study, unsubstituted flavone had been synthesized via 5-step from phenol, with 22% yield and successfully increased the yield of previous study on Fries rearrangement of phenyl acetate and benzoylation of o-HAP steps. Phenol was acetylated resulting 93% phenyl acetate. AlCl3-catalyzed Fries rearrangement in 1.5 hour and at 120 °C converted phenyl acetate into o-hydroxyacetophenone (o-HAP) with 40% yield. AlCl3 as catalyst produced o-HAP with higher and reproducible yield compared with BF3·Et2O and ZnCl2. Benzoylation of o-HAP followed by Baker-Venkataraman rearrangement of the ester product using KOH in dried pyridine produced β-diketone 1-(2- hydroxyphenyl)-3-phenylpropane-1,3-dione. The yield of ester and β-diketone were 71% and 85%, respectively. Finally, oxidative cyclization of β-diketone with sulphuric acid as catalyst produced 99% of flavone. The flavone product had been characterized spectroscopically and its melting point as well.
