Judul: Analisis Strategi Rantai Pasokan Udang Vaname (Studi Kasus Petani Plasma Tambak Pandu Karawang, Kabupaten Karawang, Jawa Barat)
Abstrak: One of the agri-fishery commodities in Indonesia, which is currently highly profitable and is a commodity shrimp. The development of shrimp consumption on the international level and national level is considered by many farmers and fishermen market potential. This is then used as an excuse to encourage improvement and development efforts on commodity shrimp. One of the business actors in the field of fisheries, especially for agribusiness commodities vaname shrimp is shrimp supply chain members vaname. Members vaname shrimp supply chain consists of four principal business consists of vaname shrimp producers, smallholders shrimp pond Pandu vaname Karawang, distributors, supermarkets and Makro. Vaname shrimp supply chain has a few problems in activities that affect the ability to generate profits. The problem is not yet well-organized supply chain between both functions in the supply chain members, starting from the seed producer to the consumer end of the causes of this supply chain is not going so well that affect each of the chain actors. Supply chain or supply chain is a distributed system where the organization of production of goods and services to its customers. This chain is also a network of various organizations are interconnected and have the same goal, ie holding the best possible procurement or distribution of goods. The purpose of this study is to identify the shrimp supply chain in the pond ECE vaname Karawang, formulate alternative strategies to improve supply chain performance of long-term vaname shrimp, formulate alternative strategies based on the best strategy was chosen for vaname shrimp supply chain. Research methods used in this research is descriptive analysis using the framework of supply chain management analysis that has been modified by Vorst. after a descriptive analysis of the shrimp supply chain vaname the next step is to make the strategy formulation stage. formulation of the strategy formulation process consists daritahap input (input), phase matching, and decision stage.Analysis of strategy formulation used in this study is the analysis of internal and external environment (IFE and EFE), SWOT analysis and the analysis QSPM.

Abstrak: Udang vaname merupakan udang introduksi yang berasal dari Amerika yang permintaannya terus meningkat di pasar dunia. Budidaya udang ini di Indonesia semakin banyak diminati karena udang ini memiliki kelangsungan hidup dan ketahanan terhadap penyakit yang lebih baik. Tingginya permintaan udang vaname mendorong pemerintah untuk meningkatkan produksi sehingga dapat bersaing di pasar dunia. Budidaya udang vaname dengan keramba jaring apung masih terdapat kelemahan dibandingkan dengan teknologi sebelumnya yaitu, tambak. Budidaya udang vaname keramba jaring apung sebelumnya masih belum pernah dilakukan sehingga kelangsungan hidup masih rendah, pengelolaan input dan output yang masih belum optimal. Oleh karena itu perlu ditinjau terkait beberapa aspek yang terdapat pada usaha udang vaname. Penelitian ini bertujuan untuk (1) Menganalisis kelayakan dari pengembangan usaha udang vaname keramba jaring apung pada masing-masing aspek (finansial, ekologi dan sosial) ?, dan (2) Menganalisis alternatif pengembangan budidaya udang vaname dengan teknologi keramba jaring apung laut ? Metode pengambilan responden secara sengaja (purposive). Analisis data yang digunakan, yaitu analisis finansial dengan melihat kinerja operasional dan perbandingan usaha yang telah ada sebelumnya yang berdasarkan pada opportunity cost serta aspek ekologi dan sosial yang menggunakan analisis Rapid Appraisal Fisheries sebagai pendukung yang menilai kelayakan dari aspek ekologi dan sosial. Untuk melakukan pengembangan suatu usaha, maka perlu adanya evaluasi terhadap suatu usaha. evaluasi dilakukan untuk menilai bagaimana suatu proyek berjalan sesuai pada saat awal perencanaan yang ditanamkan pada suatu usaha bisa menguntungkan. Dari hasil penelitian diperoleh bahwa kelayakan dari pengembangan usaha udang vaname pada aspek finansial yang masih menunjukkan nilai B/C < 1. Hal ini dikarenakan secara aktual produksi dari usaha udang vaname terbesar pada tahun 2016 sebesar 438 kg/Tahun ini masih jauh dari nilai BEP yaitu 886 kg/Tahun. Secara finansial usaha udang vaname masih belum layak. Apabila dibandingkan dengan altenatif usaha lainnya dapat dilihat bahwa opportunity cost yang hilang saat memilih usaha udang vaname yaitu sebesar Rp. 84 740 000/Th. Aspek ekologi dengan aspek sosial dengan nilai indeks keberlanjutan pada kategori cukup berkelanjutan maka dapat dikategorikan layak untuk pengembangan usaha udang vaname keramba jaring apung laut., Vannamei shrimp is an introduced shrimp from America whose demand continues to increase in the world market. Cultivation of this shrimp in Indonesia is increasingly in demand because this shrimp has better survival and resistance to disease. The high demand for vaname shrimp encourages the government to increase production so that it can compete in the world market. The cultivation of vaname shrimp with floating cages still has weaknesses compared to the previous technology, namely ponds. Previously, floating cages vannamei shrimp cultivation has never been carried out so that the survival is still low, the management of input and output is still not optimal. Therefore, it needs to be reviewed related to several aspects contained in the vaname shrimp business. This study aims to (1) analyze the feasibility of developing a vannamei shrimp business in each aspect (financial, economic, ecological and social), and (2) to analyze the alternative development of vannamei shrimp farming using floating cages technology. The method of taking respondents intentionally (purposive). The data of analysis used, namely financial analysis by looking at operational performance and comparisons of existing

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
