Judul: Floristic and phytosociology of bryophytes of the Lore Lindu National Park, Sulawesi
Abstrak: Sulawesi has a high biodiversity of phanerogams and high degree of endemism. Phytogeographically Sulawesi is part of East Malesia; it is separated from the West Malesia by the Wallace's line. As compared to adjacent major island in Malesia, the number of bryophytes species which were found in Sulawesi is low.

Judul: Karakteristik Ekologi Hutan Tropis Pegunungan di Taman Nasional Lore Lindu Sulawesi Tengah
Abstrak: Tropical montane forest ecosystem making up 21 percent of the total area of the world’s tropical forest. This ecosystem has high level of species diversity, constributes positively to the water catchment, and provides an essential habitat for many endemic and threatened plant and animal species. The objectives of this research were 1) to determine plant species diversity, 2) to study composition of vegetation community and tropical montane forest structures. This study was conducted at three primary forest sites were located in Lore Lindu National Park, Central Sulawesi. The first site was located in Watukilo at 900 m asl, the second site was in Torongkilo at 1 500 m asl, and the third site was in Torenali at 2 300 m asl around 1.5 km to peak of Mount Rorekatimbu. All sites are submontane forest, lower montane forest, and upper montane forest respectively. Plot-based plant inventory and identification were carried out in the period of July 2011 to July 2012. Plot size was 40 m x 60 m (0.24 ha) devided up into a 10 m x 10 m grid. All trees of diameter at breast height (dbh) ≥10 cm (at 1.3 m). Within each of the 10 m x 10 m, one 5 m x 5 m-sized subplot was surveyed (0.06 ha per plot) to study saplings (2 cm ≤ dbh < 10 cm), and one 2 m x 2 m-sized subplot (0.024 ha) to additionaly study understorey vegetation in each of the 5 m x 5 m subplot. We recorded a total 310 plant species belonging to 129 genera and 106 families in all forest types. Lower montane forest has the highest species richness (61 tree species, 51 sapling species, 57 seedling species, and 56 understorey plant species), followed by submontane forest and upper montane forest. Shannon diversity index showed that all forest types in this study has moderate to high in species diversity (2 < H' < 4), and has low similarity in species composition with the similarity <10% (Sørensen index). Among the species recorded, only one species that found in all three forest types, i.e. Lithocarpus celebicus (Fagaceae). In submontane forest, the most dominant tree species were Castanopsis buruana (Fagaceae), Gironniera subaequalis (Cannabaceae) and Santiria apiculata (Burseraceae), while the most dominant saplings were C. buruana, S. apiculata and Praravinia mindanaensis (Rubiaceae). For seedlings and understorey, the most dominant species were Antidesma riparium subsp. riparum (Phyllanthaceae) and Calamus sp.1 (Arecaceae), respectively. In lower montane forest, the most dominant tree species were Platea excelsa var. borneensis (Icacinaceae), Elaeocarpus sp.1 (Elaeocarpaceae) and Magnolia carsonii var. carsonii (Magnoliaceae), while the most dominant saplings were Lophopetalum beccarianum (Celastraceae), Ardisia forbesii (Primulaceae) and Cyathea contaminans (Cyatheaceae). For seedlings and understorey, the most dominant species were Calophyllum soualattri (Calophyllaceae) and Calamus sp.5, respectively. In upper montane forest, the most dominant tree species were Phyllocladus hypophylla (Podocarpaceae), Dacrycarpus steupii (Podocarpaceae) and Lithocarpus havilandii (Fagaceae), while the most dominant saplings were Trimenia papuana (Trimeniaceae), Tasmannia piperita (Winteraceae) and Myrsine minutifolia (Primulaceae). For seedlings and understorey, the most dominant species were Myrsine minutifolia (Primulaceae) and Sonerilla pumila (Melastomataceae), respectively.

Judul: Pembuatan kecap ikan secara hidrolisis kimia dari daging merah Ikan Tuna (Thunnus albacares)
Abstrak: Umumnya ikan tuna ditangani dan dimanfaatkan dalam bentuk segar atau diproses menjadi loin tuna beku dan tuna kaleng. Selama proses pengolahan loin tuna beku akan dihasilkan sejumlah limbah, diantaranya daging merah ikan tuna. Daging merah ikan tuna ini sebenarnya masih dapat dimanfaatkan, salah satunya menjadi kecap ikan. secara Kecap ikan dapat dibuat dengan cepat, yaitu hidrolisis asam dengan menggunakan HCl 6 N pada suhu 80 85° C selama 18 jam. Untuk meningkatkan nilai organoleptiknya, maka dapat digunakan karamel. Penelitian ini bertujuan untuk memanfaatkan limbah berupa daging merah hasil pengolahan loin tuna beku menjadi produk yang memiliki nilai ekonomis dalam waktu yang lebih singkat. Selain itu juga untuk mendapatkan kecap ikan yang berprotein tinggi dengan cara mengetahui pengaruh perbandingan ikan dengan HCl yang digunakan serta mengetahui pengaruh penambahan karamel terhadap mutu kecap ikan yang dihasilkan terutama nilai leptiknya. Perbandingan ikan dengan HCl yang adalah 2: 1 (A1), 1:1 (A2), 12 (A3). organo- dicobakan Sedangkan ...
