Characteristic and Catalytic for Mordenite and Zsm-5 Reaction in Produce Hydrocarbons

Conversion of methanol to the use of the treated mordenite and ZSM-5 studied in this description. Mordenite catalyst activity which showed a decrease in activity without modified quickly. After hydrothermally dealuminated mordenite done and acidification with HCl, it turns out that longer life of the catalyst thus obtained. Furthermore treated mordenite showed high selectivity to olefin formation. Acidity is measured with predictably by Spectrophotometer Infra Red observations of pyridine adsorbed, also signal of the adsorbed NO. Number of sites was reduced in the presence of acid dealumination treatment. There is no longer detectable acidity found in mordenite which has dealuminated well. Pore volume measured by the adsorption of toluene. The better stability and selectivity of the catalyst in forming various olefins in the use of the treated mordenite discussed here in terms of acidity and shape selectivity

A Virtual Ethnography Study: The Role of Cultural Radios in Campursari Music Proliferation in East Java

Campursari music is a trend on the radio and a favorite of the people of East Java, so it is shifting towards popular culture. This study aims to uncover the proliferation of campursari music and the role of cultural radios. This qualitative research uses a virtual ethnography method, which focuses on the physical presence and virtual text together. The subjects are technology (radio and communication technology on the internet), humans (radio listeners), physical interactions, and virtual interactions. Data collection used participant observation through observation and interviews offline and online in the form of various texts, writings, images, and audiovisuals on Facebook, Twitter, WhatsApp, Instagram, and Youtube. The informants of this study were four cultural experts, namely: Sumadi, Anton Sani, Ibnu Hajar, and Juwono. This study carried out participatory involvement for one year in the virtual world and 30 days living in four cities: Surabaya, Nganjuk, Banyuwangi, and Sumenep. Manthous's campursari music is a fusion of pentatonic and diatonic scales despite the addition of various musical instruments. It has several sub-genres, including campursari janger, campursari kendang-kempul, campursari keroncong dangdut, campursari dangdut Madura, campursari jaranan dangdut, campursari dangdut koplo, campursari dangdut hip-hop, and campursari dangdut acoustic. Cultural programs and campursari music reinforce the reliability of radio to maintain local culture (Javanese, Madura, Using). They are a means of maintaining local identities to stem global culture. No matter how hard the invasion of foreign culture, can not disrupt the local tastes of people. Campursari music proliferation is a modification to traditional music to serve the tastes of the people, to avoid it from extinction. Campursari music must be able to adapt to the current era. The four radio cultures in East Java make campursari music a primary commodity to attract radio listeners and as part of the lives of local people

Fungsi Masjid Dalam Pendidikan Islam Bagi Masyarakat (Studi Empirik Di Masjid Umar Bin Khattab Ngabeyan, Kartasura)

Masjid merupakan tempat yang sangat penting bagi umat Islam, sebab masjid berfungsi sebagai pusat kegiatan umat Islam. Masjid pada masa Rasulullah memiliki beberapa fungsi seperti tempat ibadah, pusat pembinaan akhlak jamaah, pengembangan agama Islam, dan pusat dakwah dan pelayanan sosial.

Digital Capitalism Today: IT Industry-Led Public Private Partnerships in a Northeastern School

There has been considerable zeal regarding the democratizing promises of information and communication technologies (ICTs). This belief has resulted in the proliferation of ICT development initiatives in education through public private partnerships. However, there are critical scholars who caution against an overly celebratory perspective of ICTs and expose the ways in which they may be contributing to the exacerbation of existing inequalities. This thesis was inspired by Dan Schiller’s book, Digital Capitalism (1999) with the purpose of examining how digital capitalism is evident today. \u27Digital capitalism\u27 refers to the relationship between politics, economics, and technology that explains the shift in the use of the Internet from aiding government agencies to serving private commercial interests. Through a political economy of communication approach, this thesis examines a new model of public schools in which IT companies are partnering with various cities and districts to equip students with the 21st century skills needed to participate in the labor market. These partnerships are designed to benefit marginalized youth that do not have access to ICTs so the study looks at one of these schools encompassing this new innovative model in order to examine the benefits and limitations of these partnerships The purpose of this thesis is to examine the way digital capitalism is playing out in education today in order to shed light on the political and economic forces driving these initiatives while examining who the decision makers are as well as who benefits and why. It has a dual objective of contributing to current digital inequality scholarship and informing policy-making. This thesis ultimately argues that there is a need for more targeted and individualized policies that serve each district’s unique needs, which works to fulfill the policy objective. It challenges the notion that technology is a neutral artifact that is separate from broader political, social, and economic processes

ISLAM NUSANTARA

Islam datang dan masuk ke Nusantara (Indonesia) melalui para wali dari Negara Mesir atau Yaman ada juga yang berasal dari cina dan india, menuju pintu utama Nusantara yaitu Aceh Serambi Mekkah sampai Sumsel, Banten, Jawa Barat, Jateng, dan Jatim, Surabaya berikut sekitarnya. Mereka ini semua kategori orang asing tetapi mengerti dan memahami Sosial Nusantara, sekaligus kehadiran Islam dapat di terima dengan terbuka, tidak terjadi konflik yang merugikan.

PLAYING NICE IN THE SANDBOX: EXPLORING THE BEHAVIORS OF EXECUTIVE AND OPERATIONAL LEADERS IN CROSS-SECTOR COLLABORATION

Educational attainment in the United States is at the highest levels since recording started, yet large numbers of students are not completing education at the secondary and postsecondary levels. This lack of education impacts their long-term prospects for living wage careers, stable housing and the ability to support both themselves and their families. A growing response to this crisis is the development of cross-sector collaborative partnerships to address educational attainment resulting in an educated and skilled workforce that will ultimately improve prosperity in a community or region. This collaborative work has expanded as a result of growing recognition that all sectors of the economy have a stake in education as a way to create strong communities and regional prosperity. While evidence of the challenges in educating all students abounds, evidence of success in collaborative partnership efforts to improve education is sparse. This constructivist grounded theory research study was developed to explore the collaborative behaviors leading to success in improving educational outcomes for all students. Leaders at the executive and operational levels of collaborative partnerships participated in this study through a three-phase process of semi-structured interviews. Data collection and analysis for this study used a process of constant comparison and occurred simultaneously with a comprehensive literature review. Participants in this research study represented collaborative partnerships from across the United States that are focused on improving educational attainment at the secondary and postsecondary levels. Four findings from this research study support an overarching substantive grounded theory that explicates the importance of moral purpose as the underpinning for achievement of collaborative outcomes. The findings further describe the behaviors necessary for success in crafting strong relationships, building trust, and communicating for impact. These interpersonal behaviors can be supported by the presence of psychological safety at the group level to maximize the efficacy of collaborative partnerships to achieve systems improvements in education. This study also encourages all collaborative partnerships to consider using a continuous improvement approach to their work grounded in intellectual humility. The study concludes with recommendations for future research to further explore the implications of psychological safety in the context of collaborative partnerships, noting that both intellectual humility and curiosity are aligned with the concepts of psychological safety and continuous improvement or improvement science
