Judul: Value Added Analysis and Sustainable Community-Based Waste Management Strategies (Case Study: Akademi Kompos  Jakarta)
Abstrak: Sebanyak 90,8% sampah warga DKI Jakarta yang tidak terkelola, mendorong pemerintah mewajibkan masyarakat untuk mengelola sampah rumah tangga. Akademi Kompos Jakarta (Akkom) merupakan salah satu kelompok pengelolaa n sampah dengan berbagai program unggulan. Tujuan penelitian ini adalah menganalisis persepsi masyarakat, menganalisis nilai tambah pengelolaan sampah organik menjadi pupuk kompos, serta menganalisis strategi pengelolaan sampah berbasis masyarakat (PSBM) berkelanjutan. Penelitian ini menggunakan metode Likert untuk menganalisis persepsi masyarakat, metode Hayami untuk menganalisis nilai tambah, dan analisis SWOT untuk menganalisis strategi PSBM. Berdasarkan hasil penelitian, masyarakat merasakan pengaruh positif maupun negatif dalam aspek ekonomi, sosial, dan lingkungan terhadap Akkom. Pengolahan sampah organik menjadi pupuk kompos Akkom memberikan nilai tambah sebesar Rp492,00/kg dengan tingkat keuntungan 97,46% atau Rp479,50/kg bahan baku sampah organik. Strategi pengelolaan yang dapat dilakukan oleh Akkom yaitu bekerjasama dengan pemerintah dan organisasi kepemudaan untuk meningkatka n partisipasi masyarakat., As much as 90.8% of DKI Jakarta residents' waste is not managed, prompting the government to oblige the public to manage household waste. Akademi Kompos Jakarta (Akkom) is one of the waste management groups with various excellent programs. The purpose of this study was to analyze public perceptions, analyze the added value of managing organic waste into compost, and analyze sustainab le community-based waste management (PSBM) strategies. This study uses the Likert method to analyze people's perceptions, the Hayami method to analyze added value, and the SWOT analysis to analyze the PSBM strategy. Based on the results of the study, the community felt positive and negative influences in the economic, social, and environmental aspects of Akkom. Processing organic waste into compost Akkom provides added value of Rp492,00/kg with a profit rate of 97,46% or Rp479,50/kg of raw materials for organic waste. The management strategy that can be carried out by Akkom is collaborating with the government and youth organizations to increase community participation.

Judul: Analisis Kelayakan Usaha Pengelolaan Sampah Berbasis Komunitas di Provinsi DKI Jakarta
Abstrak: DKI Jakarta is one of regions with the biggest amount of waste in Indonesia. The amount of waste in 2010 was 6 139.33 tons per day and gradually increases up to 1.38% per year from 1987 to 2010. This research focus on analyze the management of community-based waste in the Village of Kapuk Muara, Penjaringan District, Jakarta Utara Province either based on the analysis of market aspects, technical aspects, management aspects, and socio-economicenvironmental aspects and financial aspects. There are two scenarios were used: (i) full investment from Pertamina CSR programs and (ii) alternative investment by non-governmental program. Based on market aspects, technical aspects, management aspects, and socio-economic aspects of the environment shows that community-based waste management business is feasible. Refer to financial analysis of both scenarios is feasible, respectively in scenario I and scenario II with NPV Rp48 345 205 and Rp130 972 376; IRR of 10.41 and 26.91 per cent; B / C ratio of 1.22 and 2.36 and PBP 7.7 and 4.85 years. Both scenarios are very sensitive to deviation of price the amount of plastic compared to the production of plastics.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
