Adiabatic quantum pumping through surface states in 3D topological insulators
No full textWe 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
Full text linkIndonesian 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.

Alternatif Konsep Kelembagaan untuk Penajaman Operasionalisasi dalam Penelitian Sosiologi
Full text linkEnglishThe 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
Full text linkThis 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

Kekerabatan Beberapa Aksesi Padi Lokal Tahan Hama Penyakit Berdasarkan Analisis Polimorfisme Marka SSR
Full text linkThe level of phylogeny among local rice that has identified the resistances to plant pests and diseases needs to be studied to determine the genetic distance, so that information can be used for a recommendation parental crosses. Simple sequence repeat (SSR) markers could be used as one tool to know the degree of phylogeny and the genetic distance between genotypes. The aim of this study was to determine phylogenetic tree and the coefficient of genetic distance of several local rice resistant to host and pest based polymorphic analysis of SSR markers. Fifteen host and pest resistant local rice and one popular variety (Ciherang) were used. Molecular analysis was carried out using eighteen SSR markers. The banding patterns of DNA amplification resulted from PCR on polyacrylamide electrophoresis gel was documented by using UV Transilluminator. The phylogenetic tree showed three clearly separated clusters. Cluster 1 consisted of indica accessions resistant to blast and BLB: Gadis Langsat, Kebo, Bandang Si Gadis, Ciherang, Jawa Wangi Sleman, Marahmay, Takong, Ampek Panjang, Benoraja, and Siawak. Cluster 2 consisted of javanica and indica accessions resistant to BPH, tungro, blast, and BLB: Ase Balucung, Ase Bukne, Pare Lottong, Pare Pulu, and Jadul. Cluster 3 consisted of japonica accession resistant to blast: Kapas. The farthest genetic distance was between Pare Pulu and Ampek Panjang (DA = 0.816). The closest genetic distance was between Pare Pulu dan Pare Lottong (DA = 0.098). This research data can be used as a reference in determining the crossing parents that will be used in plant breeding program for varieties improvement of Indonesian local rice
