Analysis of Southern Segment of Sumatran Fault Monitoring Bench Mark as Preliminary Approach in Updating Earthquake Hazard Map

Sumatran Fault is one of hazard located in Sumatra Island. Southern segment of Sumatran fault is one of sources of earthquakes in Lampung Province. Hazard map is used as consideration in developing region. The source of hazard comes from stress accumulation of crust which can be derived from movement of points in surface. The study of points or monitoring bench mark to accommodate more precise fault movement or slip and stress accumulation is important for sustainable development in Lampung Province. Tool used for analysis is geographic information system especially buffer analysis. Available monitoring bench mark is analysed so that each bench mark can be classified based on its contribution of fault movement based on distance from segment of current fault. High class bench marks are prioritized to be used as survey sites to monitor fault movement. The other analysis is analysis to obtain region that lack bench mark to monitor segment of current fault or even discover new fault which is branch of segment of current fault. The result of this research is there are four high class bench marks. 58.54% of total segments of 164.020 km long Sumatran fault in Lampung Province is segments with no monitoring bench marks. Three most possible district to build bench mark are Airhitam, Lemong, and Ngambur District

Pengaruh Penambahan Serat Bambu Terhadap Kuda-kuda Beton Komposit Tulangan Bambu Agrebat Batu Pumice

Indonesia termasuk Negara dengan jumlah penduduk yang banyak. Bahkan setiap tahun jumlahnya mengalami peningkatan. Hal ini berpengaruh pada jumlah tempat tinggal yang ada di Indonesia. Suatu struktur bangunan yang dibebani akan mengalami defleksi akibat dari beban. Defleksi merupakan lendutan struktur dari posisi awal tanpa beban. Permasalahan yang terjadi adalah struktur kuda-kuda yang kombinasinya diganti, agar mendapat praktis digunakan dan lebih ringan dari beton komposit biasanya untuk mempermudah pemasangannya. Dari tulangan baja ini semakin lama akan semakin menipis dan dapat berakibat pada kenaikan harga tulangan baja. Maka dari itu, masyarakat perlu mencari alternatif_baru pengganti_tulangan baja_pada beton. Salah satu alternatif penggantinya tulangan baja pada beton merupakan dengan menggunakan bambu. Juga dalam penggunaan batu kerikil yang dianggap berat diganti dengan menggunakan batu pumice. Penelitian dilakukan dengan perlakuan membuat kuda-kuda beton komposit bertulangan bambu beragregat batu kerikil dan juga membuat kuda-kuda beton komposit bertulangan bambu beragregat batu pumice yang serat dan tidak menggunakan serat. Penggunaan serat di dalam kuda-kuda beton komposit bertulangan bambu beragregat batu Pumice ini bertujuan untuk mengurangi retakan yang terjadi di kuda-kuda tersebut

Does Microcredit Bring the Women into Economic World: Evidence from Bangladesh

The empowerment, entrepreneurship and education are the most imperative issues among women to develop the country. Micro credit is one of the effective tools to eradicate poverty among poor people through enhancing women empowerment, enhancing the entrepreneurial activities and improving education level for both men and women. It has initiated the schemes to encourage entrepreneurial activities along with developing education level and enhance the women empowerment in the country. The main goal of this research is to inspect the improvement of women empowerment, evaluate the development of entrepreneurship and the education level among micro credit borrowers in Bangladesh. There are two hundred and thirty respondents were participated in this research. The data were analyzed by the descriptive and multiple linear regression analysis. The results found that the women empowerment slightly develops even though it is not significant statistically whereas the entrepreneurship and education are negatively associated with micro credit programs. This research influences the micro credit institutions to develop and focus on the application of loaned amount by borrowers to affect significantly on women empowerment, entrepreneurial activities and education level. Finally, this research is also merits the government to widen the facilities and lessen the hardship on micro credit institutions and encourages the policy in Bangladesh.     Keywords: Micro credit, women entrepreneurship, women empowerment, poverty alleviation, Banglades

Characterization of flow rate and Heat Loss in Heating, Ventilation and Air Conditioning (HVAC) Duct System for Office Building

A building is an assemblage that is firmly attached to the ground and provides the performance of human activities and need to be considered in the daily operation in that building. The improvements in building performance are focused on improving the energy efficiency of buildings. This is approach by designing heating, ventilation and air conditioning (HVAC) duct system due to one of the most utilized energy in maintaining building performance and environment. The objectives of this research is to calculate the air (CFM) supply in office building, to characterize the velocity and head loss in a round and rectangular HVAC ducting system at various duct thickness and to optimize the thickness of the duct in HVAC system according to ASHRAE Standard. The increasing of velocity in duct system shows the increasing of head loss. The round duct design gives the lowest velocity and head loss in HVAC system approximately around 9.35% as compared to rectangular duct at 0.06 inches thickness. Hence, the trends of the head loss and duct thickness has influenced in reducing noise in HVAC duct system in order to select the best design concepts which is round shape design

Analisis Potensi Wilayah Penyebab Banjir DAS Opak Dengan Memanfaatkan Penginderaan Jauh dan Sistem Informasi Geografis

Floods often occur in several rivers in the Opak Watershed. The impact that the various public facilities submerged, disrupting the activity of local communities and floods cause losses both social and economic. This study aims to 1) determine the magnitude of the peak discharge (Qp) Opak watershed using rational methods, 2) Knowing Opak sub watershed potentially cause flooding, 3) to analyze the biophysical parameters that influence the differences in water discharge in the Opak sub watershed. This research method using field survey method, combined Landsat imagery interpretation techniques, and using methods Cook and Rational method for calculating the maximum discharge of the formula Q max = CIA/360 m3/sec. Landsat 8 is done interpretation and processed into maps of land use, subsequently amended as vector data. Map RBI processed and obtained a high point, from a high point extracted into the map slope. Geographic Information Systems applied to overlay, fourth vector data (land use, soil texture, density flow and slope) to obtain price runoff coefficient (C). Using Gumbel distribution and formula Mononobe, rainfall data of 30 rainfall monitoring stations for 10 years (2005-2014) in the Opak Watershed processed to obtain maximum intensity value (I). The study area was divided into 10 sub watershed which is Winongo Kecil sub watershed, Winongo sub watershed, Bulus sub watershed, Mruwe sub watershed, Kuning sub watershed, Code sub watershed, Gajah Wong sub watershed, Wareng sub watershed, Opak Kecil sub watershed and Tepus sub watershed. The results showed sub watershed which that have potential flood there are 4, namely, Code sub watershed with excess flow of 17,72 m3/ sec, due to have a run off coefficient which is great on landuse, Kuning sub watershed is 15,53 m3/sec, due to having a large coefficient of run off on slope, Winongo Kecil sub watershed is 23,34 m3/sec, due to have a run off coefficient which is great on landuse and Bulus sub watershed is 16,97 m3/sec due to having a large coefficient of run off on the soil texture.Soil texture in Bulus sub watershed is clay, the texture has nature hard to absorb water, so when the rains come this area will be inundated and the resulting value becomes large run off.
