Judul: Good Manufacturing Practices Assessment and Shelf-life Analysis of Chili Paste Mushroom in Chaiyo Farm
Abstrak: Mushroom as food product has big potential to be used. The nutritional content of mushroom that suitable for low energy diet and good source of protein become the reason of mushroom popularity. Schizophyllum commune has been known as one of edible mushroom that has functional properties. In Southern of Thailand, this mushroom becomes one of the famous food that been sold commercially with chili or curry paste seasoning. In this research, we assessed the Thailand’s GMP application of the producer. Besides that, this research also measured the shelf-life of chili paste mushroom product in room temperature and made a comparison with the addition of mixed preservative (propyl-parabens 500 ppm and calcium propionate 1000 ppm). From the GMP application, Chaiyo Farm as a producer still needs great numbers of improvement due to a lot of nonconformities. The longest shelf-life of product, chili paste mushroom, was estimated less than six days with addition of preservative at room temperature.

Judul: Identifikasi Kejadian Banjir Rob (Pasang) di DAS Sunter pada 9-13 Januari 2008.
Abstrak: Banjir Rob merupakan fenomena meluapnya air laut ke daratan, istilah tersebut pertama kali dikenal di daerah Semarang. Fenomena banjir Rob dipengaruhi oleh pasang surut air laut. Pasang surut sendiri dipengaruhi gravitasi bulan dan matahari, serta dipengaruhi pula posisi bulan dan matahari terhadap bumi. Banjir ini biasa terjadi pada saat pasang air laut yaitu bertepatan dengan kejadian bulan baru dan bulan purnama. Pada bulan Januari 2008, di wilayah utara Jakarta yang berbatasan dengan laut, fenomena banjir Rob (pasang) melanda kawasan tersebut. Fenomena ini mengakibatkan sejumlah kawasan di wilayah utara Jakarta terendam air laut, hal ini diperburuk dengan penurunan muka tanah Jakarta. Selain dilanda banjir pasang air laut, kawasan utara Jakarta sering dilanda banjir akibat luapan sungai-sungai yang bermuara di Jakarta, salah satu sungai yang menyumbang banjir Jakarta adalah sungai Sunter. Tutupan lahan di DAS Sunter yang sebagian besar berupa pemukiman makin meningkatkan limpasan permukaan ketika terjadi hujan. Tanggal 9-13 Januari 2008 di perairan Teluk Jakarta sedang terjadi pasang air laut karena bertepatan dengan bulan baru yang mengakibatkan terjadinya banjir Rob di beberapa wilayah di Jakarta Utara, termasuk DAS Sunter. Berdasarkan pemetaan banjir Rob di DAS Sunter pada tanggal 9-13 Januari 2008 diketahui bahwa daerah yang tergenang air laut yaitu Kalibaru dan Marunda dengan tinggi genangan 48-72 cm. Luas genangan maksimum terjadi pada tanggal 11 Januari 2008 yaitu sebesar 66.000 m2. Pada tanggal 9-13 Januari, DAS Sunter tidak ikut menyumbangkan limpasan permukaan yang dapat menyebabkan banjir karena nilai limpasan permukaan berkisar 0-3,03 mm. Sehingga kejadian banjir pada tanggal 9-13 Januari 2008 di DAS Sunter hanya berasal dari pasang air laut. Kata Kunci : Banjir Rob, Pasang-Surut, Limpasan Permukaan, DAS Sunter.
