No full textThe May 27, 2006 tectonic earthquake that rocked the Bantul area of Yogyakarta and several areas in Central Java resulted in a lot of damage to buildings and casualties. Earthquake is a disaster that can be minimized by disaster mitigation, one of which is the seismic vulnerability index data of an area. This study aims to compare the microzonation of the seismic susceptibility index (Kg) as a result of measurement of microtremor signals by processing data Vs30 USGS. The data used were 30 microtremor signal measurement points and topographic models from the USGS website in Prambanan and Gantiwarno Districts, Klaten Regency. The calculation result of Vs30 USGS shows the value of seismic vulnerability index (Kg), which ranges from to . Meanwhile, the seismic vulnerability index value (Kg) results from the measurement of the microtremor signal, which ranges from to . Comparative graphs of data from measurements of microtremor signals with the results of processing Vs30 USGS produced R-values square small. This is due to several factors, namely the shift of measurement points with data points Vs30 USGS (longitude and latitude slightly shifted). In addition, the results of calculation of Vs30 USGS are based on the topography of the earth\u27s surface which is limited to a depth of 30 meters so that it does not represent the results of measurement data directly
Achieving Sustainability in Manufacturing Micro, Small and Medium Enterprises (MSMEs’) in Tanzania Through Adoption of Solar Energy: Solar energy adoption by manufacturing MSMEs in Tanzania
No full textGlobally, energy demand has increased significantly whereby consumption of nonrenewable energy is dominant. The reliance on nonrenewable energy sources, not only threatens the efforts to achieve the stated Sustainable Development Goals but also affects community’s participation in the economic activities. The increased concern over resource depletion, and environmental impacts, has suggested future reliance on renewable energy. Tanzania has high levels of solar energy, whose exploitation could contribute significantly to energy access. Despite the benefits of renewable energy use, studies to establish factors for energy choice by manufacturing Micro Small and Medium Enterprises (MSME’s) in Tanzania are inadequate. Hence, this study intended to establish the dominant factors for the choice of solar energy by manufacturing industries, and workers perceptions about sustainable manufacturing practices. A cross sectional survey research design was employed whereas questionnaires were used to collect data (n = 236) from employees working in the manufacturing MSMEs’ in the selected districts in Morogoro region. A descriptive, Confirmatory Factor Analysis (CFA) and a multinomial probit (MNP) model were employed to establish the dominant factors for the solar energy use. The MNP results (tested at: 95% confidence level) indicated that not expensive energy source (Pvalue = 0.01) and other factors, including availability of solar appliances (Pvalue = 0.02) have significant influence on industry’s choice of solar energy, while choice of hydro-electricity was significantly influenced by not expensive (Pvalue = 0.01) and advised to use energy source (Pvalue = 0.001). Easy access (Pvalue = 006), and not expensive energy source (Pvalue = 0.001) were found to have significant influence on the use of fossil fuels. Also, the CFA results indicated that all factors i.e., environmental, social, and economic have significant influence on the workers perception about sustainable manufacturing practices. The results therefore, provides critical information to policy making institutions in Tanzania to make informed decisions on the formulation of national strategies that attracts use of renewable energy for manufacturing sustainability

No full textYogyakarta is one of the regions in Indonesia whose tourism sector has been affected by the Covid-19 pandemic. All tourism actors, especially onAlmost none of the MSME and informal sectors can escape the economic downturn due to the Covid-19 pandemic. They lost their income because tourist visits dropped by almost 100 percent. This is very worrying because it is known that Yogyakarta is one of the cities which is a tourist destination in Indonesia. The reopening of tourism objects after Covid-19 has become a momentum and turning point in promoting and developing the potential for halal tourism in DIY. The establishment of DIY as one of the National Priority Halal Destinations by the Ministry of Tourism in 2018 prompted the DIY government to encourage tourism actors such as restaurants and hotels to take part in halal certification from the Indonesian Ulema Council to ensure and increase consumer confidence in the halal tourism services provided.In general, the problems that are the object of discussion and are resolved within the scope of this research include identifying indicators that must be considered in developing tourism in DIY so that it complies with the Covid-19 Health protocol and the concept of Halal Tourism. In addition, it will also determine the characteristics of the Tourism Information System needed by Stakeholders in order to be able to support the implementation of the Covid-19 Health Protocol in the "New Normal" era and the implementation of Halal Tourism as a promising option. And finally in this research will also provide a proposal for a prototype / Information System Innovation that can be used and replicated by stakeholders in the Tourism sector, especially in DI

No full textBangsa Indonesia memiliki warisan khazanah manuskrip dengan genre dan tema pembahasan yang beragam termasuk di bidang keislaman. Sebagai data sejarah, manuskrip serta sumber-sumber sejarah lainnya seperti arsip, penting untuk mengungkap gambaran historis dinamika perkembangan Islam di Nusantara, khususnya di bidang pendidikan. Sayangnya jika dibandingkan penelitian sejarah keislaman tematik di bidang aqidah, fiqih, dan lainnya, tema sejarah pendidikan Islam masih belum banyak dieksplorasi lebih lanjut khususnya oleh kalangan akademisi di bidang pendidikan Islam. Terlebih di masa pandemi, mobilitas yang serba terbatas menjadi tantangan bagi para peneliti untuk mengakses data penelitian yang dibutuhkan. Penelitian ini bertujuan untuk menganalisis potensi pengembangan penelitian di bidang sejarah pendidikan Islam Nusantara di masa pandemi dengan memanfaatkan sumber-sumber sejarah yang dapat diakses secara digital. Penelitian ini juga mengeksplorasi pentingnya pemanfaatan perspektif pendidikan Islam dalam penelitian sejarah pendidikan Islam di Nusantara. Penelitian kajian pustaka ini menggunakan metode deskriptif kualitatif, dengan content anlysis sebagai teknik analisis datanya. Penelitian ini menyimpulkan perlunya mendorong penelitian-penelitian sejarah pendidikan Islam Nusantara dengan pendekatan yang integratif-interkonektif lintas disiplin. Guna menghasikan hasil interpretasi sejarah yang lebih komprehensif, selain perspektif pendidikan, peneliti dapat menggunakan data-data sejarah yang relatif jarang diakses di kalangan sarjana pendidikan Islam. Peneliti dapat memanfaatkan akses terbuka secara online atas arsip dan manuskrip yang telah didigitalisasi oleh intitusi seperti Perpusnas RI, DREAMSEA dan British Library. Pemanfaatan e-resources ini tentunya tetap harus berpegang pada prinsip kritis atas validitas data digital yang digunakan, baik dalam hal verifikasi isi data maupun kredibilitas laman penyedia data dengan memperhatikan panduan penggunaan data yang berlaku
