Penggunaan pestisida yang tidak terkontrol akan mengganggu agroekosistem pertanian dan mencemari lingkungan. Jumlah pestisida yang beredar di Indonesia tahun 2006 terdaftar sebanyak 1336 formulasi, 2008 sebanyak 1702 formulasi, 2010 sebanyak 2048 formulasi, 2011 sebanyak 2247 formulasi. Di dalam tanah, karbon aktif peranan sebagai shelter atau rumah untuk mikroorganisme. Pori-pori kecil pada karbon aktif digunakan sebagai tempat tinggal bakteri, sedangkan pori besar dan retakan (cracks) digunakan sebagai tempat berkumpul. Penelitian dilakukan di Laboratorium Mikrobiologi Pusat Penelitian Biologi LIPI Cibinong Mei 2011 s/d Agustus 2011.Tujuan penelitian adalah menyeleksi bakteri dalam tanah yang berpotensi mendegradasi residu insektisida yang bersifat persistent organic poluttants (POPs). Isolasi dan karakterisasi mikroba pendegradasi POPs dilakukan dengan tiga tahapan, yaitu (1) Isolasi dan identifikasi mikroba pendegradasi POPs, (2) Uji karakteristik pertumbuhan isolat pada berbagai jenis POPs, dan (3) Penetapan residu insektisida POPs hasil kultur. Hasil terdapat 7 (tujuh) isolat yang mampu mendegradasi senyawa POPs, Lima isolat bersifat gram positif (BOB1, BOB2, BOB3, BOB4, BOB5) efektif untuk mendegradasi POPs berbahan aktif: lindan, heptaklor, DDT, dan dieldrin, sedangkan dua isolat bersifat gram negatif (BOB6 dan BOB7) efektif untuk mendegradasi POPs berbahan aktif aldrin. Kata Kunci: Arang Aktif, Senyawa POPs, Bakteri Pendegardasi

The residential area which is on the outskirts of the Jongaya Canal as one of the causes of pollution of the abiotic environment such as high quality garbage accumulation which has an impact on the pollution of Losari Beach as one of the landmarks of Makassar City. The Bontorannu urban area has several potentials that can be used as a supporting factor to encourage the revitalization of channels that can be used as air transportation because the Jongaya canal can be connected to Losari Beach and the surrounding islands, Coastal corridor fishing settlements (Makassar City RTRW 2015-2034) have a value more as an Integrated Business and Tourism Center. The purpose of community service is to 1) Identify the characteristics of the infrastructure of community settlements and the community's preference for the edge settlement of the Jongaya Canal in the Bontorannu Village, Mariso District, Makassar City. 2) Arranging directives in the slums in the Bontorannu Village, Mariso District, Makassar City, based on the community. The method used is appropriate stimulus assistance for the community because the required stimulus is engineered so that people's perceptions of the environment and settlements are as expected. The socialization on structuring the settlement area infrastructure has been carried out and approved by the people of the banks of the Jongaya canal directly, and has received feedback from the participants about the suggestions and assistance on how to improve community-based settlement infrastructure

Dense settlements on the outskirts of Jongaya Canal, Bontorannu Urban Village, are one of the causes of the pollution of the Losari beach environment as a landmark in Makassar. The accumulation of rubbish along the canal further strengthens people's behavior in disposing garbage in the canal. The Bontorannu urban area has several potentials that can be used as supporting factors in revitalization efforts, namely canals that can be used as water transportation because the Jongaya canal can be connected to Losari Beach and surrounding islands. As a fisherman settlements located in urban area and also in a strategic area of a coastal corridor that has more value as an Integrated Business and Tourism Center (Makassar City RTRW 2015-2034), it certainly becomes an attraction. The purpose of community dedication is to 1) Identify the characteristics of the infrastructure of community settlements and the community's preference for the condition of the edge of the Jongaya Canal settlement in the Bontorannu Village, Mariso District, Makassar City. 2) Arranging the direction of environmental structuring in slums in Bontorannu Sub-district Mariso District Makassar City based on community. The method used is a focus group discussion (FGD) to get input on the needs and problems in their environment as well as providing appropriate stimulus to the community so that community perceptions and proposals for handling problems with the environment and settlement conditions are as expected. Recommended directions for dealing with settlement conditions include: procurement of street lights, addition of trash bins in each corridor and canal edge, land acquisition in RW 1, RW 2, RW 3, and RW 4 to open road access, provide parking area for tourists who come to visit, as well as the desire of the community to sell culinary, souvenirs, and making photo spots to attract tourists to increase the community economy.

Penelitian ini dilatarbelakangi oleh permasalahan hasil belajar Tematik peserta didik kelas III SDN Marga Kaya yang rendah. Tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran Cooperative Learning tipe Think Pair Share (TPS) terhadap hasil belajar tematik kelas III SDN Marga Kaya. Jenis penelitian ini adalah quasi Eksperimen dengan desain pretest-posttest control group design dan pendekatan deskriptif kuantitatif. Populasi penelitian ini adalah seluruh siswa kelas III SDN Marga Kaya. Teknik pengambilan sampel menggunakan purposive sampling. Sampel terdiri atas dua kelas A dan B berjumlah 61 siswa. Teknik pengumpulan data pada penelitian ini berupa tes uraian dianalisis dengan non-parametrik, yaitu Mann Whitney U. Hasil pengujian hipotesis diperoleh nilai taraf signifikansi (2-tailed) 0,000 < 0,05. Nilai rata-rata postest kelas eksperimen = 87,25 dan nilai rata-rata postest kelas kontrol = 78,21. Dengan demikian model pembelajaran Cooperative Learning tipe Think Pair Share (TPS) ini berpengaruh terhadap hasil belajar.
