Judul: Analisis model konveyor pneumatik tipe hisab skala laboratorium untuk bahan kedelai (Glycine max.)
Abstrak: Kedelai merupakan salah satu bahan utama masyarakat Indonesia. Kedelai termasuk biji-bijian yang mudah rusak sejak saat panen hingga pasca panen. Penyusutan pasca panen kedelai bisa mencapai 14.2% dan pada bagian pengeringan sebesar 2.7%. Karena itu penanganan pasca panen yang sangat baik sangat diperlukan dalam mengurangi susut hingga 10-23%(Esmay,1987). Penggunaan mesin pengering kedelai membutuhkan waktu lebih singkat, tidak tergantung cuaca serta tidak memerlukan tempat yang terlalu luas dibandingkan dengan penjemuran. Namun, mesin pengering kedelai membutuhkan biaya yang lebih tinggi. Seiring dengan kemajuan teknologi dan peningkatan produksi, mesin pengering berkapasitas besar dengan waktu pengeringan lebih singkat sangat dibutuhkan.

Judul: Pengeringan Kedelai (Glycine max (L) Merril) dengan Alat Pengering model Sumur
Abstrak: Kedelai (Glycine max (L) Merril) merupakan tanaman sumber protein yang penting di Indonesia yang diharapkan produksinya dapat terus meningkat. Oleh karena itu perlu dilakukan usaha-usaha untuk mencari faktor penghambat produksi kedelai, salah satu diantaranya adalah penanganan pasca pvlen yaitu pengeringan. Pengeringan dengan penjemuran masih banyak dilakukan petani. Pengeringan cara i n i menbutuhkan walrtu yang relatif lama dan mutu tergantung pada cuaca, untuk itu diperlukan alat pengering sederhana, praktis, dan menghasilkan mutu bahan yang baik.

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.
