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. Through literature, the authors of Indonesia express ideas and thoughts for the people of Indonesia
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

THE EFFECTIVENESS OF ICT UTILIZATION ON COGNITIVE ACHIEVEMENT IN THE VOCATIONAL EDUCATION DURING THE COVID-19 OUTBREAK IN INDONESIA
Full text linkIn the current Covid-19 transition period, it is very necessary to use innovative vocational learning models in digital models. The number of vocational learning models using ICT as the main tool during the pandemic needs to be studied further on how the model is implemented and its effectiveness. The problem that arises is that we do not know whether the use of ICT tools in vocational learning is effectively used. This study aims to empirically verify the effectiveness of ICT in vocational education learning during the Covid-19 transition period. Meta-Analysis is used as a method to conduct this research. There are 30 latest articles reviewed during the year of 2020 to 2021. All articles are classified based on the author, year of publication, the ICT device or application used, and the results of the post-test experimental and control classes. The results are obtained after the calculation using the effect size (ES) formula. The calculation results show that the learning using ICT as a tool during the Covid-19 pandemic has a high effect (1.28) on cognitive achievement in vocational education. The conclusion of this study is that ICT-assisted learning has a high level of effectiveness and is suitable for learning in the vocational field. Then, the dominant multimedia device or application used in the vocational learning in Indonesia is the computer technology network and it is the most widely used for the application of ICT in learning
PEMANFAATAN BIOCHAR KULIT BUAH KAKAO DAN SEKAM PADI UNTUK MENINGKATKAN PRODUKTIVITAS PADI SAWAH DI ULTISOL LAMPUNG
Full text linkUtilization of Biochar of Cocoa Shell and Rice Husk to Increase Rice Productivity in Ultisol Lampung. Biochar application as soil amendment is technology for soil and crop productivity improvement in acid soil. The main problem of acid soil including in paddy field is high concentration of Al3+ that inhibit crops growth causing low crop production. The objective of this study was to evaluate the effects of cocoa shell and rice husk biochar on paddyfield productivity and soil chemical properties. The study was conducted at Agricultural Research Station of Tamanbogo, East Lampung on June-September 2012 (planting season 1), January-April 2013 (planting season 2) and December 2013-March 2014 (planting season 3). The experimental design was split plot design, which the main plotswere two types of biochar (cacao shell and rice husk), the sub plots were biochar rates 0.5 t/ha (control), 5 t/ha and 15 t/ha with five replications. The parameters measured were paddy growth, yield and soil chemical properties (soil pH,C organic, N total, available P, K total, and Al3+ ). The result showed that biochar could affect weight of rice straw andrice yield at the second and third planting season, while biochar rates could affect crop growth and yield of rice at three planting. The effect of cacao shell and rice husk biochar application with the rate of 15 t/ha could up to three planting seasons without any biochar addition in following two consecutives year, whereas addition biochar 5 t/ha wasless effective. The cacao shell biochar was more effective in increasing crop growth and yield than rice husk biochar,as seen on dry grain rice yield, i.e. 3.58 t/ha (PS1) and 5.06 t/ha (PS III). During two planting seasons, both biochar at the rate of 15 t/ha were sufficient to improve soil chemical properties. Cacao shell biochar with the rate of 15 t/ha had better effect in improving soil chemical properties significantly in term of soil pH, available P, and total K content and decreasing aluminum content than rice husk biochar especially at second planting season. lowland, biochar, rice, Ultisol, LampungABSTRAKAplikasi biochar sebagai pembenah tanah merupakan salah satu teknologi untuk memperbaiki produktivitas tanah dan tanaman pada lahan masam. Permasalahan utama pada lahan masam adalah tingginya konsentrasi Fe3+ yang dapat menghambat pertumbuhan tanaman sehingga menyebabkan rendahnya produksi. Tujuan penelitian ini adalah untuk mempelajari pengaruh pemberian biochar kulit buah kakao dan sekam padi serta takarannya terhadap peningkatan sifat kimia tanah dan produktivitas padi sawah di Ultisol Lampung. Penelitian dilaksanakan pada lahan sawah di Kebun Percobaan Taman Bogo, Lampung selama tiga musim tanam yaitu bulan Juni-September 2012 (musim tanam pertama), bulan Januari-April 2013 (musim tanam kedua) dan Desember 2013 - Maret 2014 (musim tanam ketiga). Percobaan disusun dalam rancangan kelompok petak terpisah, sebagai petak utama terdiri dari biochar kulit buah kakao dan biochar sekam padi, sedangkan sebagai anak petak adalah takaran biochar yaitu tanpa biochar (kontrol 0 t/ha), 5 t/ha dan 15 t/ha, dengan 5 kali ulangan. Parameter yang diamati meliputi pertumbuhan dan hasil padi, sifat kimia tanah (pH, C-organik, N-total, P-tersedia, K-total dan Al3+ ). Hasil penelitian menunjukkan bahwa jenis biochar hanya berpengaruh nyata terhadap berat jerami kering dan hasil gabah pada musim tanaman kedua dan ketiga, sedangkan takaran biochar berpengaruh nyata terhadap pertumbuhan dan hasil padi pada ke tiga musim tanam. Pengaruh pemberian biochar kulit buah kakao dan sekam padi 15 t/ha mampu bertahan sampai tiga musim tanam dilihat dari pertumbuhan dan hasil padi sawah, sedangkan pemberian biochar 5 t/ha bertahan satu musim saja. Efektivitas biochar kulit buah kakao dalam mendukung pertumbuhan dan hasil tanaman lebih tinggi dibandingkan sekam padi terlihat dari hasil gabah kering panen sebesar 3,58 t/ha (MT II) dan 5,06 t/ha (MT III). Selama dua musim tanam pemberian biochar kulit buah kakao sebanyak 15 t/ha juga mampu meningkatkan pH tanah, P tersedia, dan kandungan K tetapi menurunkan kandungan aluminium melebihi biochar sekam padi terutama pada musim tanam kedua.produktivitas, padi sawah, biochar, Ultiso
ATCA-based ATLAS FTK input interface system
No full textThe first stage of the ATLAS Fast TracKer (FTK) is an ATCA-based input interface system, where hits from the entire silicon tracker must be clustered and organized into overlapping eta-phi trigger towers before being sent to the tracking processors. First, FTK Input Mezzanine cards receive hit data and perform clustering to reduce data volume. Then, the ATCA-based Data Formatter system will organize the trigger tower data, sharing data among boards over a full-mesh backplane. The board and system level performance studies and implementation details, as well as the operation experiences from the FTK full-chain testing, will be presented
