Judul: Kesehatan Karang Fungiidae di Pulau Pari, Kepulauan Seribu
Abstrak: Coral disease is one of the main causes of the decline of coral reef ecosystems. Fungiidae had been chosen because if compared to other corals, Fungiidae had an advantage in the ecological quantitative survey. The study aims to measure the level of coral health based on abundance and prevalence of coral health category. The study was conducted on 24 to 25 November 2013 in Pari Island, Thousand Islands on 4 stations spread. The method used in this study is Belt Transect method with 2 x 100 meters and Line Intercept Transect ( LIT ) along 30 meters with three replications. Based on the research conducted, 5 Fungiidae was found with Fungia genus dominated. The health condition of corals Fungiidae in Pari Island is divided into fourcategories that are 35% healty and 65% sick consisting of tissue discoloration-white (coral bleaching), tissue discoloration-non white (yellow band disease), and compromised health (sedimentation damage).

Abstrak: Traveling is become a world-wide trend which has been done by many nature lovers. Indonesia, which has many islands, becomes a magnet for tourists to see its underwater beauty. One of these islands is Kepulauan Seribu. Tourism activity causes several damages to coral reef ecosystems. One of them is coral disease, which resulted in the degradation of coral reef ecosystems in the world. This study aims to measure the coral reefs' health rate based on the observation of the abundance and prevalence of coral disease, and analyze the impact of tourism activity on coral reefs' health. This study was conducted from 24 to 25 November 2013 in Pari Island, Kepulauan Seribu, with 4 scattered stations. The method used was the Belt Transect method in the area of 2 x 100 meters, and Line Intercept Transect ( LIT ) in 30 meters long with three replications. Based on the result of the research, coral bleaching phenomenon was found in tourism and non-tourism area. Meanwhile, the most common diseases and health problems in this area are ulcerative white spots (UWS) and sediment damage (SD).

Judul: Kajian Penggunaan Zeolit dan Kalsium Oksida sebagai Sumber Pemanas Kemasan Kaleng Panas Sendiri (self-heating can).
Abstrak: Penelitian ini mengkaji penggunaan zeolit sebagai alternatif sumber pemanas pada kemasan kaleng panas sendiri yang umumnya menggunakan kalsium oksida. Pada penelitian ini telah dilakukan proses kalsinasi pada suhu 550 oC selama 24 jam terhadap zeolit dan kalsium oksida untuk pembakaran awal dengan tujuan menghilangkan zat-zat yang tidak diinginkan. Kemudian telah dilakukan pengukuran suhu reaksi campuran sejumlah sampel dengan sejumlah air pada masing-masing perbandingan. Hasil penelitian menunjukkan reaksi air dengan kalsium oksida menghasilkan suhu tertinggi pada perbandingan 3:1 dengan ratarata perubahan suhu 46.37 oC. Sedangkan reaksi air dengan zeolit menghasilkan suhu tertinggi pada perbandingan 1:2 dengan rata-rata perubahan suhu 39.27 oC. Massa kalsium oksida yang digunakan 5.00 gram dan zeolit yang digunakan 28.00 gram. Kemudian telah dilakukan pengukuran perubahan volume sampel yang direaksikan dengan air, hasilnya kalsium oksida dan air memiliki kenaikan volume 1.00 ml sedangkan zeolit memiliki kenaikan volume 2.00 ml. Dari hasil penelitian ini dapat disimpulkan bahwa zeolit ternyata belum mampu untuk menggantikan kalsium oksida sebagai sumber pemanas self-heating can dari aspek kapasitas panas yang dihasilkan dan nilai ekonomis penggunaan bahan.
