Abstract:
Microalgae biomass is an attractive feedstock for biofuels and other applications. Prior utilization the microalgae biomass must be harvested, a step that contributes largely to the overall energy and production costs. Membrane filtration is seen as a viable option for microalgae concentration. It is mainly attractive as primary step treating the diluted broth. However, its application is largely limited by membrane fouling that lowers overall process efficiency and productivity. This study provides an overview on the recent progress of the membrane technology particularly on technology to address the membrane fouling issue in microalgae filtration and upconcentration. Firstly, brief introduction of potential of microalgae biomass and membrane technology is provided. It followed by comprehensive overview of membrane fouling control approach. The membrane fouling control approaches are classified into optimization of operational parameters, membrane material development, hydrodynamic manipulation, improved module design and lastly module spacer development. Lastly, perspective on future research direction is also provided.

Abstract:
As the forefront in fiber materials development, electrospun nanofiber membrane (NFM) is potentially reliable for wastewater treatment due to its excellent properties for instance; large surface area, high porosity, tuneable pore size, and has great flux as compared to other conventional membranes. However, fouling issue will lead to degradation of membrane performance. Fouling issue can be alleviated by applying membrane surface modification. In this study, thermal annealing is applied onto nylon 6,6 nanofiber membrane with three different temperatures (60°C, 80°C and 120°C). Results show that annealing causes membrane shrinkage and reduction of membrane fiber diameter where the fiber reduced from 138.5 nm to 108.5 nm when annealed at 120°C. The optimum annealing temperature for the membrane was found to be at 60˚C as the membrane shows the highest flux at 1200 L/m2.h at 75 minutes filtration time and took longer time to get fouled (>75 minutes) compared with un-annealed membrane (55 minutes). Nylon 6,6 nanofiber membrane is also proven to give more than 90% of COD and turbidity rejection.

Abstract:
The Covid 19 pandemic period has changed the learning system, including the presence of online learning. Literature reviews from various sources state that the Flipped Learning model is an alternative model for planned online learning. Even so, the Flipped Learning model cannot be implemented directly, but it must be adapted to the conditions where students learn. The development of the Flipped Learning model in this study is supported by a Moodle-based e-learning campus, which is called MyBrilian, through the following syntax: (1) Introduction, (2) Exploration, (3) Study, (4) Exposure, and (5) Assessment. This study involved 66 students of Information System study program of Universitas Dinamika who took Basic Mathematics courses. The instrument used is the Lesson Plans, Student Learning Materials and Test Instruments. Data analysis through statistical descriptive and qualitative descriptive techniques. Based on the data analysis, it can be concluded that the learning is classified into increased knowledge on a high scale, namely N-Gain of 0.7, and based on student response questionnaire, it shows satisfactory results in each syntax. The conclusion is that the flipped learning model can be adopted as an implementation of planned online learning, by adjusting to local learning conditions and with the support of technology.

Abstract:
This article reports the effectiveness of student-initiated media in teaching speaking to ninth graders of a junior high school. Using a pre-experimental design, this study involved 85 students, being given an experimental treatment in the form of a freedom to choose and use their own media to present an English advertisement, one of the basic competences the students had to master in the semester when the data were being collected. A pre-test in the form of oral interview was given at the beginning of the study, followed by the implementation of the research treatment. At the end of the study, the students took a post-test of a similar format. In other words, the data in this study were in the form of the students’ speaking performance. With the help of SPSS, a test was employed to check the effectiveness of the media. Besides, informal interview with the students show that they felt more relaxed and less anxious when using the media while speaking. It is recommended that teachers make use of such media in the classroom for designing democratic classroom atmosphere so that students experience joyful learning and tend to speak more.

Abstract:
This research is motivated by the awareness of the importance of community preparedness against disasters, especially for island communities whose locations are in disaster-prone areas. Maringkik Island, East Lombok Regency was chosen as the research location because the island is included in the southern part of Lombok Island which has the potential for megathrust with earthquakes above 8 SR. The objectives of this study were to determine: (1) the level of community education in Maringkik Island and its effect on community readiness in dealing with current disasters, (2) the level of understanding of disaster preparedness in the community in patron-client relationships, and (3) the level of disaster preparedness in the local social system of community in Maringkik Island, East Lombok Regency. The method used in this research is mixed methods, a combination of quantitative and qualitative research. The data were collected using in-depth interviews and surveys using a questionnaire that had been prepared. The results obtained from this study are that community preparedness in facing disasters is influenced by several factors, namely the level of education and knowledge as well as existing socio-cultural values. In addition, the existing patron-client pattern actually contributes to the community's low understanding of disaster preparedness. Community behavior and preparedness in the event of a disaster are still traditional, instinctive and natural, not based on modern science. Therefore, this study recommends the importance of disaster-specific subjects in schools and routine disaster mitigation-related training from related institutions.
