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.

Judul: Dampak Kebijakan Pemerintah Terhadap Keuntungan dan Daya Saing Rumput Laut di Kepulauan Tanakeke Provinsi Sulawesi Selatan
Abstrak: Seaweed is one of the leading commodities in the Fisheries Revitalization Program in South Sulawesi. Production and export growth of seaweed over the last five years experienced a significant increase but will not be offset by the value of export receipts caused by the quality of seaweed produced in Tanakeke islands so low that the price of seaweed in the international market is low. Therefore, This study aims to analyze: (1) the level of financial and economic benefits, (2) the competitiveness of commodities seaweed the through competitive and comparative advantage, (3) the impact of government’s input-output policy on the competitiveness and benefits of commodities seaweed. Policy Analysis Matrix (PAM) was employed in this study in order to calculate the private and social prices of revenue and cost of the seaweed in which the social price was calculate from the shadow price of output is based on FOB prices in the port of export (Makassar) and private prices from seaweed adjusted real actual price received by farmers Tanakeke Islands. The results showed that: (1) the seaweed in Tanakeke islands was profitable (both privately and socially profitable), (2) it had competitive advantage (PCR < 1) and comparative advantage (DRC < 1), (3) the impact of government policy on output indicates negative result means that government intervention has not been effective so that the prices received by farmers is lower than international prices.

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.
