Judul: Analisis posisi dan peran lembaga serta pengembangan kelembagaan di Daerah Aliran Sungai (DAS) Ciliwung, Position analysis of Ciliwung watershed along with its institution role and institutional development
Abstrak: Daerah Aliran Sungai Ciliwung merupakan DAS prioritas yang memiliki nilai hidrologis, ekonomis dan sosial yang sangat penting bagi kelangsungan kehidupan masyarakat. Kondisi DAS Ciliwung saat ini masihburuk yang tercermin dari laju erosi dan sedimentasi yang tinggi dan fluktuasi debit antara musim hujan dan kemarau yang tinggi. Selain itu kerusakan DAS Ciliwung dicirikan pula oleh penurunan kualitas air sungai, pengurangan penutupan vegetasi, dan rendahnya pendapatan masyarakat. Untuk mengatasi masalah tersebut pemerintah telah melaksanakan berbagai program dan kegiatan yang terkait dengan pengelolaan DAS. Namun sampai saat ini kinerja pengelolaan DAS Ciliwung masih tergolong rendah., Ciliwung watershed is categorized to be a priority watershed in Indonesia due to its hydrologic, economic, and social importance for people lifelihood. The watershed condition so far is in critical stage indicated by high rate of soil erosion and sedimentation and fluctuated discharge between two seasons, rainy to dry season. These problems are characterized by decresing water quality, dwinlling the extent of vegetation cover, and low income of local community.

Judul: Studi Nilai dan Distribusi Biodiversitas di Daerah Aliran Sungai (DAS) Ciliwung Hulu
Abstrak: Watershed is one of the ecological boundary that has important role related to landscape sustainability. Ciliwung Watershed is categorized as super-priority watershed in Indonesia and provides landscape services particularly mentioned in this study is biodiversity value. The study sites were located in three sub-districts in the upper stream of Ciliwung Watershed (Ciawi, Megamendung, Cisarua), Bogor District of West Java. The main objectives of this study were to analyze value and distribution of biodiversity using six indicators of landscape sustainability. The six indicators (presence of threatened species, land use and land cover change, land use intensity of organic agricultural, population, occupation, and infrastructure) were analyzed using geographical information system (GIS). Based on the result, it can be shown that Cisarua and Megamendung sub-district are the first and second largest area with high biodiversity value (4 022 ha and 2 099 ha). Meanwhile, Ciawi sub-district has no area with high biodiversity value. Finally, we propose six recomendations of landscape management for biodiversity sustainability in the upper stream of Ciliwung Watershed.

Judul: Kajian Trichogrammatridea bactrae bactrae Nagaraja (Hymenoptera: trichogrammatidae) parasitoid telur Etiella zinckenella treitschke (Lepidoptera: pyralidae
Abstrak: Penelitian bertujuan mengkaji biologi T. bactrae bactrae pada telur E. zinckenella, mengkaji pengaruh tiga jenis inang terhadap biologi T. bactrae , dan mengkaji pelepasan T. bactrae dalam mengendalikan E. zinckenella. Penelitian dilaksanakan di Laboratorium Bionomi dan Ekologi Hama, Jurusan Hama Penyakit Tumbuhan, Fakultas Pertanian, Institut Pertanian Bogor, dan di lahan kedelai milik petani di Desa Mekarwangi, Kecamatan Ciranjang, Kabupaten Cianjur. Penelitian berlangsung sejak bulan Oktober 1994 sampai dengan Nopember 1995. Hasil percobaan menunjukkan bahwa pada telur E. zinckenella, persentase imago parasitoid yang muncul 97,69 %, atau mortalitas sekitar 2,31 %. Pada keadaan tersedia madu dan inang, lama hidup imago betina 46,40 jam. Masa peletakan telur sekitar 1,33 jam, dengan keperidian 18,00 butir per betina. Telur E. zinckenella umur 1 hari lebih dipilih dibandingkan umur 2 dan 3 hari, namun ketiga kelompok telur tersebut sama sesuainya untuk perkembangan parasitoid…dst
