Membrane photobioreactor as a device to increase CO2 mitigation by microalgae

The integration of a membrane contactor with a photobioreactor serves two major purposes for the mitigation of CO₂ by microalgae, i.e., to enhance the mass transfer and interfacial contact between two different phases and to increase the exchange process of CO₂-O₂ by microalgae in the photobioreactor. The membrane integrated with a photobioreactor for CO₂ mitigation by microalgae can be considered as a relatively new field, and only four or five related research efforts have been published in the literature, suggesting that a significant amount of work remains to be done in this field. In addition, all of the authors agreed that a membrane contactor is capable of achieving better mass transfer than the conventional approach of using a separation column in the gas-liquid separation process. One significant problem associated with using a membrane as a CO₂-O₂ gas exchanger is its susceptibility to pore fouling due to the micron-size cells of the microalgae. However, pore fouling can be prevented by using a hydrophobic membrane contactor and appropriate operating conditions, both of which are discussed in detail in this work

Effect of prescribed temperature on mixed convection boundary layer in the unsteady stagnation point flow toward a stretching vertical sheet

The solution to the unsteady mixed convection boundary layer flow and heat transfer problem due to a stretching vertical surface is presented in this paper. The unsteadiness in the flow and temperature fields is caused by the time-dependent of the stretching velocity and the surface temperature. The effects of the unsteadiness parameter, buoyancy parameter and Prandtl number on the flow and heat transfer characteristics are thoroughly examined. It is observed that the solutions exist for all values of buoyancy parameter. Comparison with known results for steady-state flow is excellent

PENINGKATAN PEMAHAMAN SISWA DENGAN PENGGUNAAN MODEL PEMBELAJARAN KOOPERATIF TIPE NHT(NUMBERED HEAD TOGETHER) TERHADAP PROGRAM BELAJAR SENAM DI SDN KAJJAN 02 BLEGA BANGKALAN

Pembelajaran senam membutuhkan perhatian khusus karena Senam merupakan salah satu cabang olah raga yang mengandalkan aktivitas, baik sebagai olah raga sendiri maupun untuk cabang olah raga lain. Kenyataan yang terjadi adalah penguasaan siswa terhadap materi senam masih tergolong rendah jika dibanding dengan mata pelajaran lain. Kondisi seperti ini terjadi pula pada SDN Kajjan 02 Blega, Bangkalan Berdasarkan hasil wawancara peneliti dengan siswa kelas VI bahwa penguasaan materi Senam oleh siswa masih tergolong rendah. Banyak siswa yang kurang aktif dalam mengaplikasikan atau memberikan komentar ketika diberikan perintah oleh guru. Hasil observasi awal yang dilakukan oleh peneliti pada SDN Kajjan 02 Blega, Bangkalan menunjukkan bahwa pembelajaran senam di sekolah tersebut masih menggunakan model pembelajaran konvesional yakni suatu model pembelajaran yang banyak didominasi oleh guru, sementara siswa duduk secara pasif menerima informasi pengetahuan dan keterampilan. Hal ini diduga merupakan salah satu penyebab terhambatnya kreativitas dan kemandirian siswa sehingga menurunkan prestasi belajar mata pelajaran senam. Salah satu model pembelajaran yang melibatkan peran siswa secara aktif adalah model pembelajaran kooperatif. Melalui model pembelajaran kooperatif siswa diharapkan dapat mengemukakan pemikirannya, saling bertukar pendapat, saling bekerja sama jika ada teman dalam kelompoknya yang mengalami kesulitan. Hal ini dapat meningkatkan motivasi siswa untuk mengkaji dan menguasai materi pelajaran Senam sehingga nantinya akan meningkatkan prestasi belajar siswa

Synthesis and characterization of metal oxide promoted alumina catalyst for biofuel production

Alumina has been widely used as a support in catalysis process which owing to its extremely thermal and mechanical stability, high surface area, large pore size and pore volume. The aim of this study was to synthesize calcium oxide-supported basic alumina catalysts (CaO/Al2O3) by impregnation method and to characterize the properties of the catalyst based on its surface area and porosity, functional group, surface morphology and particle size. Impregnation method was chosen for the synthesization of catalyst which involved contacting the support with the impregnating solution for a particular period of time, drying the support to remove the imbibed liquid and calcination process. In the preparation of catalyst, catalytic performance of CaO/Al2O3 catalyst was measured at different calcined temperatures (650°C, 750°C and 800°C). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Mercury intrusion porosimetry (MIP), and particle size analyzer (Zetasizer) was used to characterize the catalyst. The highest total specific area and the total porosity of the catalyst was obtained at 750oC. FTIR analysis basically studied on the functional groups present in each catalyst synthesized, while SEM analysis was observed to have pores on its surface. Moreover, CaO/Al2O3 catalysts at 650°C produced the smallest particle size (396.1 mn), while at 750°C produced the largest particle size (712.4 mn). Thus it can be concluded that CaO/Al2O3 catalysts has great potential coimnercialization since CaO has attracted many attentions compared to other alkali earth metal oxides especially on the transesterification reaction

Investigating the relationship between socio-technical congruence and software quality in software engineering project / Anjila J. Suali

Coordination in the development of a software project is essential to the process development because it could impact the software quality. Issues of coordination during development need to be identified to find out the impact on the software quality. Coordination is crucial in the development process, especially when the developers are working separately with other developers in dispersed locations. Furthermore, coordination becomes more complicated when involving a large-scale project. Failure to coordinate in the complex project impact the product quality. Product quality is one of the most important aspects when developing software. Product quality could be affected and increased the chance of product failure when the developers’ coordination are unsynchronized. Thus, there is a need to have an approach to measure whether coordination occurs among developers. Measuring developer coordination is a fundamental challenge to ensure the interdependence tasks could be completed. An approach to conceptualize and measure developer coordination is known as 'Socio-Technical Congruence (STC). STC is the “fit” between the coordination requirements established by the dependencies among tasks and the actual coordination activities carried out by the developers. Because of that, this study focuses to identify the issues of coordination and its impact to the software quality. Moreover, this study is conducted to investigate the relation between the congruence of the developer’s communication and the task dependency allocated and also the relation of STC and software quality. Systematic Mapping Study method was carried out to gather the previous literature related to the issues of coordination and its impact on software quality. Meanwhile, Mining Software Repository (MSR) method is used to extract data related to the developer’s communication and tasks allocated to the developer. The extracted data is used to measure the congruent of coordination. The study has discovered that there are 13 issues of coordination. The findings also shows that the relationship between STC and software quality is a significant positive relationship. This finding indicates that high congruence in the development could deliver a high quality of the product when it is in positive relationship. This study is expected to contribute to the body of knowledge related to the STC in software engineering field
