Adiabatic quantum pumping through surface states in 3D topological insulators
We investigate adiabatic quantum pumping of ballistic Dirac fermions on the surface of a strong three-dimensional topological insulator. Two different geometries are studied in detail, a normal metal–ferromagnetic–normal metal (NFN) junction and a ferromagnetic–normal metal–ferromagnetic (FNF) junction. Using a scattering matrix approach, we show that each time a new resonant mode appears in the transport window the pumped current exhibits a maximum and provide a detailed analysis of the position of these maxima. We also predict a characteristic difference between the pumped current in NFN- and FNF-junctions: whereas the former vanishes for carriers at normal incidence, the latter is finite due to the different nature of wavefunction interference in the junctions. Finally, we predict an experimentally distinguishable difference between the pumped current and the conductance.Quantum NanoscienceApplied Science
TINJAUAN KRITIS TERHADAP KONSEP IDEOLOGIS KEPENGARANGAN INDONESIA : KAJIAN SOSIOLOGIS
Indonesian writers continue to race across the ocean of globalization and technology. Those who come from various regions, fused into a large community as citizens of the world literature, sow among a number of mirage and cyberspace. An Indonesia poet or author has diverse languages, in accordance with the ideological background (worldview) authorship respectively. Ideology means a way of thinking or way of life of a person or a group. This paper assesses the ideology of Indonesia authorship in terms of sosilogi. Sociology is the study of society or community. Through this sociological theory discovered the concept of Indonesian author diverse ideologies. Indonesian author is able to create an ideology novelty literary language in conditions of globalization regime. Through literature, the authors of Indonesia express ideas and thoughts for the people of Indonesia
Alternatif Konsep Kelembagaan untuk Penajaman Operasionalisasi dalam Penelitian Sosiologi
EnglishThe experts have no the same perception regarding the term of “institution”. This leads to unworkable definitions and concepts. This paper reviews the existing thoughts, especially those related with the term of “organization”, and simplifies them to formulate an easier concept which enables scientists and practitioners to work with. Different meanings exist due to different points of views of the experts, especially in early stage of sociology development. Sine 1950’s, social institution and social organization have been distinguished strictly. The author proposes a solution, i.e., the term of “institution” to mention the social system in which it is classified into two important components, namely “institutional aspect” and “organizational aspect”. Through this differentiation, it is expected that the analysis becomes more detailed, signifies the strong and weak aspects, and enables to choose the strategy of developing it.IndonesianIstilah “kelembagaan” belum memperoleh kesamaan pengertian di kalangan para ahli. Hal ini menyebabkan munculnya beberapa pengertian dan konsep yang menyebabkan tidak dapat dioperasionalkan. Tulisan ini berusaha melakukan tinjauan (review) seluruh pemikiran yang berkembang, terutama kaitannya dengan istilah “organisasi”, untuk kemudian merumuskan satu konsep yang lebih mudah sehingga dapat dipergunakan baik untuk kalangan ilmuwan maupun praktisi. Ketidaksamaan pemaknaan terjadi karena setiap ahli memiliki titik pandang yang berbeda dalam membahasnya, terutama pda masa-masa awal perkembangan sosiologi. Namun, semenjak era 1950-an, sesungguhnya sudah terlihat adanya pembedaan yang tegas antara kelembagaan (social institution) dan organisasi (social organization). Sebagai solusinya, penulis menggunakan istilah “kelembagaan” untuk menyebut suatu sistem sosial dimaksud, yang didalamnya dapat dibagi menjadi dua komponen penting, yaitu “aspek kelembagaan” dan “aspek keorganisasian”. Dengan membedakan seperti ini, maka analisa dapat lebih mendalam, dapat diketahui aspek apa yang kuat dan lemah, serta dapat memilih strategi untuk pengembangannya
TANTANGAN PENGINTEGRASIAN JAMINAN KESEHATAN DAERAH KE DALAM JAMINAN KESEHATAN NASIONAL UNTUK MEWUJUDKAN CAKUPAN PELAYANAN KESEHATAN UNIVERSAL
This study is to review the facts in the health care field, where WHO has agreed to achieve Universal Health Coverage (UHC) in 2014. UHC is a health system that ensures every citizen in the population has fair access to a qualified promotive, preventive, curative, and rehabilitative health care at reasonable costs. Universal coverage contains two core elements namely equitable access to qualified health services for every citizen, and the protection of financial risks when people use health services. Indonesia is currently in transition towards UHC. Law No. 40 Year 2004 about National Social Security System (UU SJSN)' has answered the basic principles of UHC by requiring every citizen to have access to comprehensive health services that are needed through pre-effort system. Then, the author will formulate solutions to these problems which can be seen as a recommendation for the implementation of health care development. Problem solving methods used in formulating solutions to problems are policy analysis using William Dunn and Abidin's theory, and the Fishbone Diagram. Based on the analysis, the author advises the need to arrange a formulation that meets the demands of integration of Jamkesda into JKN. Formulation of policies which have been directed towards the centralization of health financing through JKN program must be balanced by providing a flexible space for local governments to participate in decision making processes dynamically. This formulation is called Centralized Dynamic Integration policy formulation.Â
Pengembangan Kawasan Jagung Berbasis Korporasi Petani di Kabupaten Lebak, Banten
The main problem faced by small-scale farming is that the economy of scale cannot be reached so that the use of inputs and technology is inefficient. To overcome this problem, farmers need to join and cooperate in a farming group. One of the models of this cooperation is the agricultural area development based on farmer corporation that combines technical business aspects with farmer institutions aspects. This study aims to analyze the achievements of a pilot project implementation of the corn area development based on farmer corporation in Lebak Regency, Banten Province, which analyzed using the evaluation model of contect, input, process, product (CIPP) and determine priority strategies which analyzed using Analytical Hierarchy Process (AHP). The result of this study shows that the pilot project targets for the first and the second years, namely cooperation with the feed industry and forming its own feed processing, respectively have not been achieved. From the identified seven success indicators, three were achieved, namely production increase, income increase, and implementation of local specific innovative technology. The strategy that needed to be set in advance as a priority was farmer empowerment through a farmer institution, with the most important factor is farmers' welfare achievement

Feasibility Study of Hybrid Maize Farming in Muna District Southeast Sulawesi Province. Maize harvest area in 2015 in Muna District was 13,159 ha with the production by 32,007 tonnes and the productivity by 2.43 t/ha. This maize productivity is still considered low, due to the results of the study AIAT Southeast Sulawesi on 2014, wich able to obtain productivity by 5 tonnes of dry seed/ha. To increase the production of maize, advocacy anddissemination of technological innovations maize using hybrid varieties had been carried out. A research was applied to investigate the production of maize as well as the income of the farmers. Research was conducted using a structured interview with questionair to 30 maize hybrids farmers and 30 local maize farmers in the Wakobalu Agung Village,Kabangka Sub District, and Bente Village, Kabawo Sub District, Muna District in October to December 2015. The results showed that based on t test, the productivity of hybrid maize was significantly higher than the local variety, so the hybrid maize planting could increase of maize productivity. Hybrid farmers applied urea and NPK while the local maize growers did not use inorganic fertilizers. Organic fertilizer was applied both by hybrid maize and local maize group, yet dose of both groups respectively was varied. Hybrid maize farming with Bima 19 URI variety and local maize was feasible, each B/C 1.07 and 1.17. However the productivity and farmers’ income of the hybrid maize was higher than the local maize. The productivity of the hybrid maize by Bima 19 URI was 4,744 kg dry grain/ha and thefarmers’ income was IDR8,596,000. The productivity of the local maize was 1,404 kg dry grain/ha as well as farmers’ income was IRD4,666,000.Hybrid maize farming, productivity, farmers' incomeABSTRAKLuas panen jagung tahun 2015 di Kabupaten Muna yaitu 13.159 ha, dengan produksi 32.007 ton, produktivitas 2,43 t/ha. Produktivitas jagung yang dicapai selama ini dinilai masih rendah, mengingat hasil kajian BPTP Sulawesi Tenggara tahun 2014 sudah mampu diperoleh produktivitas 5 ton pipilan kering/ha. Untuk meningkatkan produksi jagung, maka telah dilakukan pendampingan dan penyebaran inovasi teknologi jagung menggunakan varietas hibrida. Berkenaan dengan hal tersebut maka dilakukan penelitian untuk mengetahui produksi dan pendapatan petani.
