Judul: Pengaruh Ketebalan Dan Persen Aerasi Terhadap Sifat Fisikokimia Tempe Grits Kacang Merah (Phaseolus Vulgaris L.).
Abstrak: Kedelai merupakan sumber protein nabati utama bagi sebagian besar penduduk Indonesia dan terutama digunakan sebagai bahan bakuuntuk pembuatan tempe. Namun kacang kedelai tersebut sebagian besar dipenuhi dari impor. Agar ketergantungan terhadap kedelai dapat dikurangi, maka pembuatan tempe perlu memanfaatkan jenis kacang-kacangan lokal yang tersedia dan dapat dibudidayakan dengan baik di Indonesia. Salah satu jenis kacang yang potensial adalah kacang merah (Phaseolus vulgaris L).Penelitian ini mengembangkan tempe kacang merah, terutama dalam bentuk grits kacang merah berukuran 10 meshdengan tujuan untuk memperbaiki karakteristik tempe yang dihasilkan terutama kandungan proteinnya. Pengaruh ketebalan tempe(1, 2, dan 3 cm) serta persen aerasi (1%, 2.5%, dan 4%) terhadap sifat fisikokimia tempe grits kacang merah dijadikan sebagai perlakuan untuk diamati pengaruhnya. Bentuk grits mempengaruhi tempe yang dihasilkan, yaitu dapat meningkatkan kadar protein dan mengurangi kadar lemak. Ketebalan dan aerasi yang berbeda mempengaruhi penampakan, rendemen, warna kromatik, dan kadar protein terlarut tempe grits kacang merah. Kombinasi perlakuan (ketebalan 1 cm dan aerasi 1%) memberikan tempe yang terbaik berdasarkan parameter penampakan, rendemen, warna kromatik, kadar protein terlarut dan kemudahan untuk diproduksi.

Abstrak: One of the commodities that can be used to make tempe is red beans (Phasolus vulgaris L.). Red beans are rich in carbohydrate complex and fiber, but the protein content is lower than soybean. Therefore, process engineering is required to increase protein content and yield of red beans tempe. The raw material used in this research is grits of red beans and starter (mixture of R. oligosporus and R. oryzae (1:1)). Two process parameters studied in this research are aeration area (1%, 2.5%, 4%) and thickness of tempe (1cm, 2cm, 3cm). The result showed that the force to slice tempe decreases as the thickness of tempe increases. The brigthness of red bean tempe is lower than soybean tempe and showing cromatic colors of red and yellow. The yield of red beans grits tempe ranges between 92.11%-96.79 %. Tempe with aeration treatment 4% and thickness 1 cm having the highest protein content (41.13 % db), soluble protein 23.31 g/100 g, and higest protein digestibility 91.26 %. Process engineering (size reduction and aeration level) applied in this research increases protein content and its digestibility because of the increased surface area which eventually maximize the gowth of fungi and hidrolize protein more effectively.

Judul: Studi sistematika  Oreophryne Boettger, 1895Sulawesi (Anura: Microhylidae)
Abstrak: The cross frogs, genus Oreophryne Boettger, 1895 are most diverse in the mainland of New Guinea and adjacent islands, to the Wallacea region in the Moluccas, Sulawesi, and the Lesser Sunda Islands, even marginally to the Oriental region in Bali and to the southern Philippine Islands. In Sulawesi, this taxon consists of three species but has rarely been reported since their original descriptions and remained unstudied in both taxonomical work and molecular study. This research aims to evaluate the taxonomic status of the cross frogs in Sulawesi based on morphology and estimate the phylogenetic using the 16S rRNA gene. The phylogenetic tree was reconstructed under Maximum Likelihood (ML) and Bayesian Inference (BI) analyses. We used the specimens of Sulawesian Oreophryne which were stored at the Museum Zoologicum Bogoriense (MZB). A total of about 19 morphological characters were measured by a digital caliper and ocular micrometer to the nearest 0.01 mm. The phylogenetic tree shows that the three nominal species of Oreophryne from Sulawesi are clearly clustered. Correspondingly, the phylogenetic analysis supports the recognition of a new taxon, Oreophryne sp. However, the phylogenetic relationships between Oreophryne within Wallacea remain unresolved. Consequently, further systematic analysis along with additional sequences from the type locality is necessary to clarify the interspecific relationship among this region. We examined the morphology of 50 voucher specimens of Sulawesian Oreophryne. The validity of O. celebensis, O. variabilis, and O. zimmeri was confirmed in this study, but still the latter remains to be established. The three nominal species examined here were not collected from the type locality, so additional specimens, either in the type locality, new locations, or in other areas on this island are needed to evaluate the taxonomic status of these species deeply. Moreover, the unnamed species from the highland of the Mekongga mountains differ morphologically and genetically from all previously described Sulawesian Oreophryne. This distinct species will increase the number of cross frogs in Sulawesi to four species, all of which are endemic.
