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

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 Response of Citronella Grass on Several NPKMg Fertlization Levels in Latosol Soil Type
Full text linkCitronella grass (Cymbopogon nardus var genuinus L) is an essential oil-producing plant known as "Citronella Oil of Java". Oil is resulted from leaf distillation. The fertilization of N, P, K and Mg was expected to enhance herb productivity and oil yield of citronella grass. The research was conducted at Cicurug Experimental Garden, Sukabumi from August 2016 - February 2017. The objective of this research was to determine the proper dosage of NPKMg fertilizer on citronella grass in Latosol soil type. The study was arranged in a Randomized Block Design with 6 fertilization treatments and 4 replications. Fertilizer treatments were (1) without fertilizer (control), (2) NPKMg (12:12:17:2): (2) at the dosage of 141 kg.ha-1,(3) 281 kg.ha-1, (4) 421 kg.ha-1, (5) 526 kg.ha-1, and (6) Urea 150 kg.ha-1, SP-36 50 kg.ha-1 and KCl 125 kg.ha-1 (as comparison). The NPKMg fertilization on citronella grass enhanced plant growth and increased the productivity of biomass and oil yield. The application of NPKMg fertilization (12:12:17:2) 141 kg.ha-1 produced 23 tons of herbs, increased by 30.8 % compared to NPK fertilization without Mg. The dosage of NPKMg fertilizer (12-12-17-2) at 281 kg.ha-1 indicated the best growth and the highest herb production (24 ton.ha-1), increased by 39 %, while the highest oil content (1.4 %) was shown by 421 kg.ha-1 NPKMg (12-12-17-2) treatment, although the oil yield was insignificant compared to 281 kg.ha-1. Thus, the dosage of 281 kg.ha-1 NPKMg (12:12:17:2) can be recommended for citronella grass cultivated at Latosol soil typ

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
The Potency of Endophytic Bacteria Isolated From Red Ginger to Enhance Black Pepper Seedlings Growth
Full text linkEndophytic bacteria have many benefits such as phosphate solubilization, nitrogen fixation, increasing mineral absorption as well as enhancing plant resistance against diseases. The research aimed to obtain endophytic bacteria potential to stimulate the growth of black pepper seedling. The first step was isolating endophytic bacteria from roots, rhizomes, and leaves of healthy red ginger. Characterization and selection were conducted by evaluating the capability on phosphate solubilization, nitrogen fixation, and indole acetic acid (IAA) hormone production of the isolated endophytic bacteria. There were 36 isolates consisted of 14 isolates from leaves, 9 isolates from roots and 13 isolates from rhizomes. Seventeen isolates were capable to dissolve phosphate, fix nitrogen and produce IAA or possessing those three characters, but only nine isolates were tested on pepper seedlings. The nine isolates were Ajc 1, Ajc 3, Ajc 7, Ajc 9, Rjc 1, Rjc 6, Djc 3, Djc 6, and Djc 11. Further evaluation of the nine isolates which were inoculated to pepper seedlings, indicated that Rjc1 isolate enhanced pepper seedlings height better than other isolates
