Abstrak: Reef fish is an organism that has the greatest individu number in the coral. The purpose of this study was to assess the type and abundance of reef fish and the value of diversity index, uniformity and dominance in the area of cultivation of coral transplantation in Pramuka Island and the surrounding waters. Observations reef fish and water samples were taken from the transplant area of 5 stations in March 2015. Reef fish are found in both the transplant area totaling 1126 individuals. Families are found in both the transplant area numbered 16 families and consists of 51 species. The average value of the index of diversity at observation area in the medium category. The average value of the index uniformity at observation area was include in the category of high uniformity and stable community. The average value dominance index was calculate at observation area are in the low category dominance.

Abstrak: Coral reef is the most extensive and highly productive marine ecosystems located in the tropical ocean. The purpose of this study was to examine the structure of reef fish communities in artificial reef in Karya and Harapan Island using parameters, such as reef fish species and family abundance, reef fish trophic level, diversity, eveness, and dominance index. Based on the highest family composition of reef fish in an observation station of Karya and Harapan Island, the most dominating are Pomacentridae (Amblyglyphidodon curacao and Pomacentrus lepydogenis) and Labridae (Cirrhilabrus cyanopleura. Reef fish that are often found trofik level in the artifical reef is herbivorous reef fish 50 % (550 individuals), while reef fish that are often found based on fish group of reef fishes is major reef fish (854 individual). There are no domination by particular species on both stations. High diversity index was present, while both the stations are not significantly different with each other using Hutchinson test, uniformity index is high

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.
