Judul: Penerapan Sistem Peringatan Dini (Early Warning System ) dalam Usaha Pencegahan Kebakaran Hutan (Studi Kasus di HTI PT (Persero) Inhutani III Unit Pontianak Kalimantan Barat)
Abstrak: Pengelolaan Hutan Tanaman Industri (HTI) mengandung konsekuensi perlunya pengelolaan secara intensif termasuk di dalamnya kegiatan perlindungan, khususnya terhadap bahaya kebakaran, sebab kebakaran hutan dalam waktu yang singkat dapat menimbulkan kerusakan dan kerugian paling besar diantara faktor-faktor perusak hutan lainnya.

Judul: Sistem Peringatan Dini dalam Kegiatan Pencegahan Kebakaran Hutan di KPH Kuningan, Jawa Barat
Abstrak: Kebakaran hutan memberikan dampak negatif yang cukup besar oleh karena itu diperlukan suatu tindakan pencegahan sejak awal. Salah satu kegiatan pencegahannya yaitu menentukan daerah rawan kebakaran hutan. Tingkat persepsi masyarakat berdasarkan penelitian di beberapa desa di KPH Kuningan terhadap sistem peringatan dini tergolong tinggi untuk Desa Cihanjaro, tergolong sedang untuk Desa Simpayjaya dan tergolong rendah untuk Desa Kawungsari. Menurut aksesbilitasnya, Desa Kawungsari memiliki akses paling tinggi dengan hutan. Ada beberapa variabel penyebab kebakaran hutan antara lain : jarak antara pemukiman penduduk dengan hutan, aksesbilitas menuju hutan, dan potensi daerah terjadi konflik. Penentuan daerah rawan kebakaran hutan dapat dilihat melalui tingkat persepsi masyarakat terhadap keberadaan KPH Kuningan dan sistem peringatan dini dalam kegiatan pencegahan kebakaran hutan.

Judul: DNA Extraction and Characterization of Salmonella‟s Lytic Bacteriophage Genome
Abstrak: Bacteriophages are ubiquitous in nature and are known to proliferate wherever their bacterial hosts exist. Their virion particles can exist independently outside the host, however all phages are need their host to propagate. Several phages are highly specific to host cell surface receptors and any slight changes in structure results in little or no interaction between the phage and its host. Salmonella‟s phage isolated from sewage water where their bacteria exist. Three isolated of phages (phages 15, 19 and 38) were used in this research that concentrated using three types of methods. PEG/ NaCl method was firstly used to concentrate the phages based on their molecular weight to precipitate the phage particles during centrifugation. The second method was Scraping Plaque method. In this method, overlay plaques were scraped and collected in SM buffer to get phage concentrates. Enrichment method was the last method used to concentrate the phages. Phage genome isolation was done using two methods i.e. EDTA/SDS and Proteinase K methods. The first method was done using DNase I to eliminate bacterial DNA followed by SDS/EDTA treatment to release phages DNA and phenol-chloroform-isoamyl alcohol to extract the DNA. DNA was collected by isopropanol extraction. While in Proteinase K method, bacterial DNA was eliminated by DNase I and Proteinase K/SDS was used to degrade phages capsids and ethanol for DNA precipitation. The result showed that PEG/NaCl method resulted the highest phage concentration for phage 15 and phage 19, while scrapping method was the highest for phage 38. The quantity and purity of extracted DNA were low for PEG/NaCl and Scraping methods, while Enrichment method was higher indicated higher purity. Run on agarose gel electrophoresis of extracted DNA confirmed that Enrichment method results were the best while scraping and PEG/NaCl method was appeared smear background. Based on DNA genome size determination, the bacteriphages of Salmonella sp were comparable with other study of Salmonella phages. Phage P15 with genome size of 39,5 kb was close to phage epsilon15. Phage P19 with genome size of 41 kb was close to phage ST160. And phage P38 with genome size of 48,5 kb was close to phage Gifsy-1.
