Judul: Effects of the Price Increase of Soybean on Profitability of Small and Micro Businesses Sanan, Tempe Chips, Malang City.
Abstrak: Salah satu komoditas yang membuat Indonesia bergantung pada impor agar ketersediaannya selalu ada adalah kedelai. Akibatnya harga kedelai impor tidak terjaga kestabilannya. Kenaikan harga kedelai impor di dalam negeri disebabkan beberapa faktor seperti melemahnya nilai tukar rupiah terhadap dolar dan kenaikan harga kedelai di pasar dunia. Dampak naiknya harga kedelai adalah berkurangnya profitabilitas UMKM keripik tempe pada masing-masing skala usaha. Tujuan dari penelitian ini untuk mengetahui profitabilitas masing-masing skala usaha dan mengetahui skala usaha yang paling bertahan pada penurunan ukuran tempe. Profitabilitas usaha dihitung dengan perhitungan titik impas, Marginal Income Ratio (MIR) dan Marginal of Safety (MOS) serta dilakukan perhitungan analisis sensitivitas untuk mengetahui skala usaha yang paling bertahan pada penurunan ukuran tempe. Hasil yang diperoleh adalah usaha dengan kapasitas produksi keripik tempe paling besar tidak memiliki profitabilitas tertinggi dan tidak tahan terhadap penurunan ukuran tempe. Usaha mikro lebih menguntungkan dan lebih mampu bertahan jika dibandingkan dengan usaha kecil.

Judul: Dampak Kenaikan Harga Kedelai Terhadap Tiga Usaha Kecil dan Menengah Tahu Kota Bogor
Abstrak: Inability to meet the needs of domestic soybeans make Indonesia dependence on imports. Consequently there is no certainty of domestic supply availability and price stability of soybean. The increased price of soybeans in the country influenced by the world soybean prices often occur and cannot be avoided by tofu industries that are consumers of imported soybeans. With the diversity of tofu business scale existing in Indonesia, the impact of rising soybean prices will vary from one tofu business to others. Therefore, this study uses three samples with different scale business to compare the impact of rising soybean prices. Classification of used business scale is based on the amount of daily production capacity, that is the scale of households with a daily production capacity of ≤ 100 kg, small scale with a daily production capacity of 101-200 kg, and medium scale with a daily production capacity of 201-300 kg. The indicators used in this study is the profitability value, value-added and sensitivity. The results obtained are that v medium-sized tofu businesses generate the highest profitability value and valueadded, and are the most resistant tofu business in encountering the increased soybean prices. However, the results obtained by medium-sized tofu businesses are not much different from the value obtained by small-sized tofu businesses. Thus, in this study, small and medium-sized tofu business generate insignificantly different profitability value, value-added, and the sensitivity.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
