Basin Area

Brimob retention basin located within the Sekanak Sub-watershed system, which is a flood-prone point. Administratively, the Brimob retention basin area is a part of the Sub-district of Ilir Barat I. The research method used is computer modeling. The steps taken are: data collection, hydrological analysis, cross-sectional analysis, hydrological and hydraulic modeling using pumps. The Brimob retention basin can accommodate a volume of water up to 115,103.73 m3, up to an elevation of the embankment of + 4.30 m. The magnitude of designed rainfall is R2 = 118.78 mm, R5 = 144.78 mm, R10 = 161.99 mm and R25 = 183.73 mm. The peak discharge of each return period is Q2 = 6.30 m3 / s, Q5 = 7.67 m3/s, Q10 = 8.59 m3/s and Q25 = 9.74 m3/s. To assess the effectiveness of pump operation, 2 (two) pumping capacities are simulated, namely: 250 l / sec and 500 l / sec, each used 2 (two) pump units. The simulation used a pump with a capacity of 500 l / sec, and the amount of discharge (inflow) for each return period is as input. The conclusion is that the use of a pump with a capacity of 500 l / sec can overcome excess water volume and avoid runoff and effective in dealing with the excess water in the Brimob retention basin.

KAJIAN POTENSI HIDROLOGI EMBUNG IRIGASI WAE ROBANG DI KABUPATEN ROTE NDAOStudy The Potential Of Hidrology Wae Robang Irrigation Retention Basin In Rote Ndao DisrtrictSiti NurasiyahDepartemen Pendidikan Teknik Sipil, Universitas Pendidikan Indonesiaemail: [email protected] Ndao District is one of the districts in the province of NTT, which has a fairly extensive irrigation areas and potential but less discharge to irrigate the irrigation area. Rote Ndao District has topography is hilly and much of the basin area can hold water, so one way to solve this problem is to build retention basin to hold excess water during the rainy season. Wae Robang retention basin is one of the retention basin will be built in Rote Ndao District. One aspect that must be examined in the planning of retention basin is hydrological analysis. The purpose of the analysis of hydrology at the location of Robang Wae retention basin is to assess the potential of existing hydrological includes inflows fill retention basin, retention basin reservoirs, and flood discharge plan. From the results of the hydrological analysis showed that the volume of water that can fill an Wae Robang retention basin during the rainy season amounted to 1,774,029 m3, retention basin reservoir design capacity Wae Robang retention basin amounted to 1,348,859 m3, and the flood discharge plan with a return period of 50 years for the spillway Wae Robang retention basin amounted to 21.71 m3/ sec.Keywords: Wae Robang, retention basin, hydrologi AbstrakKabupaten Rote Ndao merupakan salah satu kabupaten di provinsi NTT yang memiliki areal irigasi yang cukup luas dan cukup potensial tetapi kekurangan debit air untuk mengairi areal irigasi tersebut. Kabupaten Rote Ndao ini memiliki kondisi topografi yang berbukit-bukit dan banyak daerah cekungan yang dapat menampung air, maka salah satu cara untuk menanggulangi masalah ini adalah dengan membangun embung yang berguna untuk menampung air yang berlebihan pada waktu musim hujan. Embung Wae Robang merupakan salah satu embung yang akan dibangun di Kabupaten Rote Ndao. Salah satu aspek yang harus ditelaah dalam perencanaan embung adalah analisis hidrologi. Tujuan dari analisis hidrologi di lokasi embung Wae Robang ini adalah untuk mengkaji potensi hidrologi yang ada meliputi aliran masuk yang mengisi embung, tampungan embung, dan debit banjir rencana. Dari hasil analisis hidrologi didapatkan bahwa volume air yang dapat mengisi kolam Embung Wae Robang selama musim hujan adalah sebesar 1.774.029 m3, kapasitas tampung desain embung Wae Robang adalah sebesar 1.348.859 m3, dan debit banjir rencana dengan kala ulang 50 tahun untuk pelimpah embung Wae Robang adalah sebesar 21,71 m3/det.Kata kunci : Wae Robang, embung, hidrologi

This paper summarizes the application of ultramicrotomy as a specimen preparation technique for some of the Materials Science applications encountered over the past two years. Specimens 20 nm thick by hundreds of μm lateral dimension are readily prepared for electron beam analysis. Materials examined include metals, plastics, ceramics, superconductors, glassy carbons and semiconductors. We have obtain chemical and structural information from these materials using HRTEM, CBED, EDX and EELS analysis. This technique has enabled cross-sectional analysis of surfaces and interfaces of engineering materials and solid state electronic devices, as well as interdiffusion studies across adjacent layers.Samples are embedded in flat embedding moulds with Epon 812 epoxy resin / Methyl Nadic Anhydride mixture, using DY064 accelerator to promote the reaction. The embedded material is vacuum processed to remove trapped air bubbles, thereby improving the strength and sectioning qualities of the cured block. The resin mixture is cured at 60 °C for a period of 80 hr and left to equilibrate at room temperature.

Objective The objective of the study was to examine specific patterns of Twitter usage using common reference to tinnitus. Method The study used cross-sectional analysis of data generated from Twitter data. Twitter content, language, reach, users, accounts, temporal trends, and social networks were examined. Results Around 70,000 tweets were identified and analyzed from May to October 2018. Of the 100 most active Twitter accounts, organizations owned 52%, individuals owned 44%, and 4% of the accounts were unknown. Commercial/for-profit and nonprofit organizations were the most common organization account owners (i.e., 26% and 16%, respectively). Seven unique tweets were identified with a reach of over 400 Twitter users. The greatest reach exceeded 2,000 users. Temporal analysis identified retweet outliers (> 200 retweets per hour) that corresponded to a widely publicized event involving the response of a Twitter user to another user's joke. Content analysis indicated that Twitter is a platform that primarily functions to advocate, share personal experiences, or share information about management of tinnitus rather than to provide social support and build relationships. Conclusions Twitter accounts owned by organizations outnumbered individual accounts, and commercial/for-profit user accounts were the most frequently active organization account type. Analyses of social media use can be helpful in discovering issues of interest to the tinnitus community as well as determining which users and organizations are dominating social network conversations.

Abstract In this study, the resistance of FIB prepared vias was characterized by the Kelvin probe technique and their physical characteristics studied using cross-sectional analysis. Two domains of resistivity were isolated in relation to the ion beam current used for the deposition of the via metal (Pt). Also submicrometer vias were investigated on 4.2 µm deep metal lines of a BiCMOS aluminum based design and a CMOS 090 copper based one. It is shown that the controlling parameter is the shape and volume of the contact, and that the contact formation is favored by the amount of over-mill of the via into the metal line it will contact.
