Judul: Financial Feasibility Study of Straw Mushroom Farming in Bojongmangu Village Subdistrict Bojongmangu of Bekasi
Abstrak: Jamur merang adalah salah satu jamur konsumsi yang memiliki permintaan tinggi, sehingga banyak dikembangkan salah satunya di Desa Bojongmagu. Produksi jamur merang di Desa Bojongmangu memiliki kelemahan, yaitu produksi yang tidak menentu sehingga relatif rentan terhadap faktor lingkungan. Hal ini akan memengaruhi keputusan petani untuk berusahatani, karena tidak diketahui secara pasti kelayakan usahatani. Investasi yang diperlukan juga tidak sedikit dan produksi yang tidak menentu akan memengaruhi kelayakan usahatani. Tujuan dari penelitian ini untuk (1) mengidentifikasi aspek-aspek kelayakan usahatani jamur merang, (2) mengestimasi kelayakan finansial usahatani jamur merang, (3) menganalisis pengaruh penurunan produksi jamur merang, penurunan harga jual jamur merang, dan peningkatan harga kapas terhadap kelayakan usahatani jamur merang. Metode analisis yang digunakan yaitu analisis kelayakan finansial, analisis sensitivitas, dan analisis switching value. Usahatani jamur merang layak untuk diusahakan, karena telah sesuai dengan aspek-aspek kelayakan serta kriteria investasi yaitu NPV, Net B/C, Gross B/C, IRR, dan Payback Period. Penurunan produksi dan harga jual jamur merang segar memberikan dampak paling besar terhadap usahatani jamur merang., Straw mushroom is one of edible mushrooms has a high demand, it is widely developed, one of them in Bojongmagu Village. Productions of straw mushroom in Bojongmangu Village has a weakness, that is erratic production it is relatively vulnerable to environmental factors. This will affect the decision of farmers to farm, because it is not known with certainty the feasibility of straw mushroom farming. The investment required is also not small and uncertain production will affect the feasibility of farming. The purpose of this research for (1) identify feasibility aspects of straw mushroom farming, (2) estimate the financial feasibility study of straw mushroom farming, (3) analyzed the effect of decreasing production of straw mushroom, decreasing selling price of straw mushroom, and increasing the price of cotton on the feasibility study straw mushroom farming. The analytical method is financial feasibility analysis, sensitivity analysis, and switching value. Straw mushroom farming is feasible, because complied with the aspects and investment criteria, that is NPV, Net B/C, Gross B/C, IRR, and Payback Period. The decrease in production and selling price of straw mushroom had the biggest impact.

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.
