Judul: Pengaruh Antioksidan dan Pemanasan dengan Drum Drier Terhadap Umur Simpan Bekatul (The Influence of Antioxidants and Heating Process by Drum Drier Against Rice Bran Shelf Life)
Abstrak: Dampak krisis ekonomi yang berkepanjangan salah satunya adalah kekurangan gizi khususnya kekurangan gizi protein pada anak-anak yaitu Kekurangan Energi Protein (KEP). Pada jangka panjang anak-anak yang menderita KEP akan mengalami penurunan daya pikir, kecerdasan, dll, sehingga terjadi Kekhawatiran akan hilangnya generasi (lost-generation),Disisi lain sebenarnya kita masih memiliki sumber protein yang murah namun belum dimanfaatkan secara optimal.

Judul: Effect of storage time, packaging type, and antioxidant addition of physical and chemical quality of rice bran
Abstrak: Lama penyimpanan cenderung meningkatkan kadar air bahan yang akan menunjang pertumbuhan jamur. Penelitian ini bertujuan mengevaluasi kualitas fisik dan kimia dedak padi dengan penambahan antioksidan pada lama penyimpanan dan jenis kemasan berbeda. Rancangan penelitian yang digunakan adalah rancangan acak lengkap faktorial 3x4 dengan 4 ulangan. Faktor W yaitu lama penyimpanan (W0: 0 minggu, W4: 4 minggu, dan W8: 8 minggu) dan faktor P yaitu jenis kemasan (P1: karung goni + 0 ppm antioksidan, P2: karung goni + 125 ppm antioksidan, P3: hermetik + 0 ppm antioksidan, dan P4: hermetik + 125 ppm antioksidan). Hasil penelitian didapatkan bahwa lama penyimpanan dan jenis kemasan dapat mempengaruhi populasi serangga, kadar air, dan kadar protein kasar dedak padi. Hasil penelitian juga didapatkan bahwa lama penyimpanan dan jenis kemasan berpengaruh nyata (P<0,05) terhadap kerapatan tumpukan, kerapatan pemadatan tumpukan, dan berat jenis dedak padi. Dapat disimpulkan bahwa jenis kemasan hermetik dapat mempertahankan kualitas fisik dan kimia dedak padi hingga penyimpanan 8 minggu. Penambahan 125 ppm antioksidan belum efektif dalam mempertahankan kualitas fisik dan kimia dedak padi., Long storage tends to increase moisture content of the material which will support the growth of mold. This research was conducted to evaluate physical and chemical quality of rice bran with antioxidant addition at different storage time and packaging type. The experiment using completely randomized design factorial 3x4 with 4 replications. Factor W was storage time (W0: 0 week, W4: 4 weeks, and W8: 8 weeks) and factor P was packaging type (P1: jute sac + 0 ppm antioxidant, P2: jute sac + 125 ppm antioxidant, P3: hermetic + 0 ppm antioxidant, and P4: hermetic + 125 ppm antioxidant). The result found that storage time and packaging type can affected insect population, moisture content, and crude protein. The result also found that storage time and packaging type significantly (P<0.05) affected bulk density, tapped density, and true density. Based on result can be concluded that hermetic packaging can maintaining physical and chemical quality of rice bran for up to 8 weeks of storage. 125 ppm antioxidant addition have not been effective in mainting physical and chemical quality of rice bran.

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.
