Relation on phitoplankton community with Litopenaeus vannamei productivity in biocrete pond

ABSTRACTManagement of phytoplankton is generally conducted by controlling the concentration of organic matter, fertilization and water exchange.  Organic materials are from uneaten feed and excretion of shrimp.  By using post facto method it was found four class of phytoplankton in biocrete pond at one cycle rearing of white shrimp (Litopenaeus vannamei).  Population at early rearing period was dominated by Bacillariophyceae (50.4%; 13 species) and Cyanophyceae (42.41%; 1 species), followed by Dynophyceae (6.2%; 5 species) and Chlorophyceae (1.3%; 1 species).  Increment in phytoplankton density was followed by increment in chlorophyll-a and oxygen from photosynthesis, and productivity was 2132 kg/pond.Keywords: phytoplankton, white shrimp, Litopenaeus vannamei, biocrete pond ABSTRAKPengelolaan fitoplankton umumnya dilakukan dengan mengoptimalkan bahan organik serta pemupukan dan pergantian air. Bahan organik berasal dari pakan buatan yang tidak terkonsumsi (sisa pakan) dan ekskresi dari udang. Dengan menggunakan metode post facto selama satu siklus pemeliharaan udang vaname (Litopenaeus vannamei) pada tambak biocrete diperoleh empat kelas fitoplankton. Dominasi Bacillariophyceae (50,4%; 13 jenis), Cyanophyceae (42,41%; 1 jenis) terjadi pada awal pemeliharaan yang diiukuti oleh Dynophyceae (6,2%; 5 jenis) dan Chlorophyceae (1,3%; 1 jenis). Peningkatan kelimpahan fitoplankton secara keseluruhan diikuti oleh peningkatan kandungan klorofil-a dan oksigen hasil fotosintesis total sehingga produktifitasnya mencapai 2132 kg/petakKata kunci: fitoplankton, udang vaname, Litopenaeus vannamei, tambak biocret

Analisis daftar minuman campuran dalam usaha meningkatkan profitabilitas di The Bar Hotel Sofitel Palm Resort, Johor Bahru, Malaysia

Penjualan minuman di suatu bar adalah merupakan transaksi yang diharapkan untuk mendapatkan keuntungan bagi pihak hotel terutama bar. Dalam skripsi ini, penulis melakukan penelitian tentang bar di Hotel Sofitel Palm Resort, Johor Bahru, Malaysia yang mempunyai nama "The Bar". Pihak manajemen Hotel Sofitel melakukan penurunan harga minuman di "The Bar" dengan harapan dapat meningkatkan volume penjualan minuman di "The Bar". Hal itu mengakibatkan terjadinya peningkatan pada biaya minuman dari 25% sampai 40% sehingga keuntungan setiap minuman menurun dan keuntungan rata-rata setiap bulannya tetap. Pihak "The Bar" ingin meningkatkan keuntungannya .dengan cara menaikkan harga minumannya kembali, namun pihak manajemen hotel tidak menyetujui langkah tersebut. Penulis membantu pihak "The Bar" untuk tetap dapat meningkatkan keuntungannya tanpa melakukan peningkatan harga jual minumannya yaitu dengan cara setiap bulannya mendorong penjualan produk minuman campuran tertentu yang mempunyai harga pokok minuman kurang dari 35%. Ada 12 jenis minuman campuran dengan harga pokok minuman kurang dari 35% yaitu terdiri dari 2 jenis minuman campuran non-alkohol dan 10 jenis minuman campuran yang beralkohol. Berdasarkan perhitungan penjualan minuman campuran yang didasarkan pada tingkat hunian rata-rata hotel setiap bulannya maka penulis menyimpulkan bahwa dengan menonjolkan 3 jenis minuman campuran dapat membantu pihak "The Bar" meningkatkan keuntungannya dengan menekan harga pokok minuman sebesar 3,37% dan meningkatkan kontribusi margin sebesar 3,37%

Surface-Attached Poly(oxanorbornene) Hydrogels with Antimicrobial and Protein-Repellent Moieties: The Quest for Simultaneous Dual Activity

By copolymerizing an amphiphilic oxanorbornene monomer bearing N- tert-butyloxycarbonyl (Boc) protected cationic groups with an oxanorbornene-functionalized poly(ethylene glycol) (PEG) macromonomer, bifunctional comb copolymers were obtained. Varying the comonomer ratios led to copolymers with PEG contents between 5–25 mol %. These polymers were simultaneously surface-immobilized on benzophenone-bearing substrates and cross-linked with pentaerythritoltetrakis(3-mercapto­propionate). They were then immersed into HCl to remove the Boc groups. The thus obtained surface-attached polymer hydrogels (called SMAMP*-co-PEG) were simultaneously antimicrobial and protein-repellent. Physical characterization data showed that the substrates used were homogeneously covered with the SMAMP*-co-PEG polymer, and that the PEG moieties tended to segregate to the polymer–air interface. Thus, with increasing PEG content, the interface became increasingly hydrophilic and protein-repellent, as demonstrated by a protein adhesion assay. With 25 mol % PEG, near-quantitative protein-adhesion was observed. The antimicrobial activity of the SMAMP*-co-PEG polymers originates from the electrostatic interaction of the cationic groups with the negatively charged cell envelope of the bacteria. However, the SMAMP*-co-PEG surfaces were only fully active against E. coli, while their activity against S. aureus was already compromised by as little as 5 mol % (18.8 mass %) PEG. The long PEG chains seem to prevent the close interaction of bacteria with the surface, and also might reduce the surface charge density

Surface Modifications of High-Performance Polymer Polyetheretherketone (PEEK) to Improve Its Biological Performance in Dentistry

This comprehensive review focuses on polyetheretherketone (PEEK), a synthetic thermoplastic polymer, for applications in dentistry. As a high-performance polymer, PEEK is intrinsically robust yet biocompatible, making it an ideal substitute for titanium—the current gold standard in dentistry. PEEK, however, is also inert due to its low surface energy and brings challenges when employed in dentistry. Inert PEEK often falls short of achieving a few critical requirements of clinical dental materials, such as adhesiveness, osseoconductivity, antibacterial properties, and resistance to tribocorrosion. This study aims to review these properties and explore the various surface modification strategies that enhance the performance of PEEK. Literatures searches were conducted on Google Scholar, Research Gate, and PubMed databases using PEEK, polyetheretherketone, osseointegration of PEEK, PEEK in dentistry, tribology of PEEK, surface modifications, dental applications, bonding strength, surface topography, adhesive in dentistry, and dental implant as keywords. Literature on the topics of surface modification to increase adhesiveness, tribology, and osseointegration of PEEK were included in the review. The unavailability of full texts was considered when excluding literature. Surface modifications via chemical strategies (such as sulfonation, plasma treatment, UV treatment, surface coating, surface polymerization, etc.) and/or physical approaches (such as sandblasting, laser treatment, accelerated neutral atom beam, layer-by-layer assembly, particle leaching, etc.) discussed in the literature are summarized and compared. Further, approaches such as the incorporation of bioactive materials, e.g., osteogenic agents, antibacterial agents, etc., to enhance the abovementioned desired properties are explored. This review presents surface modification as a critical and essential approach to enhance the biological performance of PEEK in dentistry by retaining its mechanical robustness
