Judul: Optimizing Profits from Processed Seaweed Production (Case Study of MSMEs in West Sumbawa)
Abstrak: Poklahsar Sinar Pagi merupakan Usaha Mikro, Kecil, dan Menengah (UMKM) di Kertasari dengan mayoritas mata pencaharian masyarakatnya petani rumput laut. Rumput laut yang diperoleh dikembangkan menjadi produk olahan makanan. Tantangan UMKM tersebut menggabungkan sumber daya yang tersedia guna mencapai keuntungan yang optimum. Dalam karya ilmiah ini, akan dibahas masalah pengoptimuman keuntungan. Masalah pengoptimuman keuntungan diformulasikan menggunakan metode simpleks dalam program linear serta dilakukannya analisis sensitivitas guna melihat perubahan solusi optimum. Pencarian solusinya akan diselesaikan menggunakan bantuan perangkat lunak POM QM for windows V5. Model yang dibuat memperhatikan bahan baku yang digunakan. Dalam penerapannya, model ini menghasilkan keuntungan optimum serta dapat mengetahui tingkat optimum terhadap kemungkinan perubahan setiap variabel yang terlibat, nantinya akan digunakan dalam proses produksi UMKM tersebut., Poklahsar Sinar Pagi is a Micro, Small and Medium Enterprises (MSME) in Kertasari, where most of the people's livelihood is seaweed farmers. The obtained seaweed is developed into processed food products. The challenge for MSMEs is to combine available resources in order to achieve optimum benefits. In this scientific work, the problem of profit optimization will be discussed. The profit optimization problem is formulated using the simplex method in a linear programming and a sensitivity analysis is carried out to see changes in the optimum solution. The search for a solution will be solved using the POM QM for Windows V5 software. The model made pays attention to the raw materials used. In its application, this model produces optimum profits and can determine the optimum level of possible changes in each variable involved, which will later be used in the MSMEs production process.

Abstrak: Shrimp production at Subdistrict Cantigi Regency Indramayu is still not optimal such as production factor is limited, pond management is not efficient, and farmer’s knowledge about shrimp farming is low. The target research is to analyze optimization input use and financial elegibility at Subdistrict Cantigi. Method used by case study with intake sampel method in the form of purposive sampling. Analyse data use method analyse function produce Cobb-Douglas and analyse finansial. input use Efficiency anticipation got a optimal input is 7/m2 for fry, 0,0217 kg/m2 for feed, 0,0229 hour/m2 to pump, 0,0016 hour/m2 for the preparation labour, 0,0142 hour/m2 for the conservancy labour, 0,0049 hour/m2 for the labour harvest and 0,0031 kg/m2 for saponin. Analyse the production of tiger prawn at optimal condition is R/C 4,51, Pay Back Period 0,42 year, and iii Break Even Point equal to Rp 4.735.940. Invesment criteria analysis with third scenario represent best scenario with value NPV equal to 517.669.132, Net B/C 26.79 and IRR equal to 469%. analysis Sensitivity with change price of feed at 28% indicating that effort still be competent to be run

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.
