The conclusion in this study was that there were Aedes sp mosquito larvae and there was correlation between the density of Aedes sp mosquito larvae with the incidence of dengue fever and dengue fever in the working area of ??the Tanah JawaCommunityHealth Center, Tanah Jawa District, Simalungun district in 2022.

Persaingan usaha yang semakin masif menuntun perusahaan untuk mempertahankan usahanya. Dalam menjalankan kegiatan usaha, perusahaan membutuhkan dana yang didapatkan dari keuangan perusahaan ataupun dari pinjam meminjam uang. Pelaksanaan pemberian pinjaman uang membutuhkan jaminan kebendaan salah satunya yang dibebani hak tanggungan yang diberikan oleh debitor atau pihak ketiga. Ketika debitor wanprestasi kreditor dapat langsung melakukan eksekusi dan mengambil pelunasan piutangnya. Berbeda halnya jika debitor dinyatakan pailit, kreditor pemegang jaminan selaku kreditor separatis dalam melakukan eksekusi harus tunduk pada Undang-Undang Nomor 37 Tahun 2004 tentang Kepailitan dan Penundaan Kewajiban Pembayaran Utang. Mengingat kepailitan adalah sita umum semua kekayaan debitor pailit yang pengurusan dan pemberesannya dilakukan oleh kurator dibawah pengawasan hakim pengawas. Namun menjadi pertanyaan bagaimanakah kedudukan jaminan kebendaan yang dibebani hak tanggungan milik pihak ketiga selaku pemberi jaminan dalam kepailitan. Untuk menjawab permasalahan tersebut penelitian ini menggunakan metode penelitian normatif dengan teknik pengumpulan data studi kepustakaan dan pendekatan perundang-undangan. Hasil pembahasan didapatkan kedudukan jaminan kebendaan yang dibebani hak tanggungan milik pihak ketiga selaku pemberi jaminan dalam kepailitan bukanlah termasuk ke dalam harta pailit (non boedel pailit). Akan tetapi, karena tidak ada pengertian khusus tentang harta pailit mengakibatkan ketidakpastian hukum terhadap kedudukan jaminan kebendaan yang diberikan oleh pihak ketiga.

Populasi dalam penelitian ini adalah siswa di dua sekolah tersebut dengan jumlah keseluruhan sample banyak 50 responden. Data yang di dapat akan diolah menggunkan uji T-Test.  Siswa adiwiyata yang berpengetahuan baik sebanyak 68% dan siswa yang berpengetahuan kurang sebanyak 38% dan siswa non adiwiyata berpengetahuan baik sebanyak 48% dan berpengetahuan kurang 56%. Dapat disimpulkan pengetahuan siswa terhadap penggunaan plastik yang bersekolah pada progran adiwiyata, lebih baik dari pada siswa yang bersekolah pada sekolah non adiwiyata. Hasil penelitian diperoleh bahwa independent sample T-Test bernilai sig.(2-tailed) 0.004 < 0,05 maka perbedaan bermakna secara statistik atau signifikan pada probabilitas 0,05. Dapat disimpulkan bahwa terdapat perbedaan pengetahuan yang sifnifikan antara siswa adiwiyata dengan siswa non adiwiyata tentang penggunaan plastik. Dengan demikian siswa yang memiliki  pengetahuan penggunaan plastik lebih baik terdapat pada siswa yang bersekolah pada program awidiyata.

Excessive use of plastic bags adversely affects health and the environment based on their hard-to-decompose nature. The increase in the number of plastic bag use is strongly influenced by population growth and changes in people's lifestyles, especially in shopping patterns among housewives, besides that government policies related to the Covid pandemic have triggered an increase in the use of plastic bags.
