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

TRANSFORMASI GEN PADA NILAM UNTUK KETAHANAN TERHADAP PENYAKIT UTAMA MENGGUNAKAN Agrobacterium tumefaciens
<p class="IsiabstrakIndonesia">Nilam banyak dibudidayakan di Indonesia, dan lebih dari 80% produksi minyak nilam dunia dipasok dari Indonesia. Masalah utama dalam budidaya nilam di Indonesia adalah penyakit, seperti penyakit layu bakteri, budok dan nematoda. Sampai saat ini varietas tahan terhadap penyakit, khususnya budok, belum diperoleh. Tanaman tahan dapat diperoleh dengan teknik transformasi gen. Transkripsi faktor WRKY telah diketahui dapat meregulasi serangan beberapa patogen penyebab penyakit tanaman. Gen <em>OsWRKY76</em> terletak pada segmen kromosom 9 tanaman padi yang telah diidentifikasi terkait dengan ketahanan berspektrum luas. Penelitian bertujuan untuk mengintroduksikan konstruksi gen <em>OsWRKY76</em> yang berasal dari padi ke dalam tanaman nilam melalui bantuan <em>Agrobacterium tumefaciens</em>. Pada percobaan pertama, tanaman nilam ditransformasi dengan <em>A. tumefaciens</em> strain EHA 105 yang mengandung gen <em>OsWRKY76</em>. Perlakuan terdiri atas waktu induksi eksplan yang akan ditransformasi (pre-kultur) di dalam medium MS, yaitu 5 dan 7 hari, dan waktu inokulasi <em>A. tumefaciens</em> yaitu 10 dan 20 menit. Pada percobaan kedua, analisis molekuler untuk mengkonfirmasi keberadaan gen <em>OsWRKY76</em> dalam tanaman nilam menggunakan teknik PCR dengan primer <em>hptII</em>. Hasil penelitian menunjukkan waktu induksi eksplan terbaik sebelum transformasi adalah 5 hari, dengan perendaman di dalam suspensi <em>A. tumefaciens</em> selama 10 menit. Dari transformasi tersebut telah dihasilkan 187 kalus independen. Hasil analisis PCR terhadap galur-galur putatif transgenik independen, lima galur (T1, T8, T10, T11, T13) positif mengandung gen <em>hptII</em>, yaitu gen penanda ketahanan terhadap antibiotik higromisin yang berada satu konstruk dengan gen <em>OsWRKY76</em>. Hasil tersebut menunjukkan bahwa gen <em>OsWRKY76</em> yang berasal dari padi dapat diintroduksikan pada tanaman nilam dan berpeluang sebagai kandidat tahan terhadap penyakit utama.</p></jats:p

Dampak Kebijakan Subsidi Pupuk Terhadap Daya Saing Komoditas Sayuran Di Bali (the Impact of Fertilizer Subsidy Policy on the Competitiveness of Vegetable Commodities in Bali)
Usahatani sayuran dinilai tidak berdaya saing dan kurang menguntungkan karena mahalnya harga input produksi tidak seimbang dengan harga output yang dihasilkan. Hal ini menyebabkan produksi sayuran di Bali semakin berkurang sehingga harus mendatangkan pasokan sayuran dari luar Bali. Penelitian ini betujuan untuk: (1) mengetahui daya saing USAhatani sayuran di Bali dan (2) mengetahui dampak kebijakan subsidi pupuk pemerintah terhadap pengembangan USAhatani sayuran di Bali. Penelitian ini dilakukan di Kabupaten Tabanan Provinsi Bali dengan pertimbangan bahwa kabupaten tersebut merupakan sentra produksi sayuran di Bali. Penelitian ini dilakukan dengan pendekatan Focus Group Discussion (FGD) yang dihadiri oleh 50 orang petani sayuran sebagai sampel penelitian. Data yang diperoleh dalam penelitian ini adalah data primer berupa data input output dalam berusahatani sayuran yang diterapkan petani selama tahun 2014. Metode analisis yang digunakan dalam mengolah data adalah Policy Analysis Matrix (PAM). Hasil penelitian menunjukkan bahwa USAhatani sayuran di Bali masih memiliki keunggulan komparatif dan kompetitif terutama pada USAhatani komoditas cabai merah, cabai rawit dan tomat. Kebijakan subsidi pupuk dari pemerintah berdampak pada pengembangan USAhatani sayuran di Bali terutama pada USAhatani cabai merah, sawi hijau dan kubis/kol. Untuk meningkatkan daya saing USAhatani sayuran dan merangsang petani meningkatkan produksi sayuran di Bali diharapkan pemerintah daerah mampu memberikan kebijakan tambahan berupa: subsidi obat-obatan yang selama ini masih dibeli dengan harga impor oleh petani dan menetapkan kebijakan harga output pada komoditas sayuran.KeywordsUsahatani sayuran; Daya saing; Policy analysis matrix; Bal
THE EFFECTIVENESS OF ICT UTILIZATION ON COGNITIVE ACHIEVEMENT IN THE VOCATIONAL EDUCATION DURING THE COVID-19 OUTBREAK IN INDONESIA
In 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
Dampak Program Gerakan Tanam Cabai Terhadap Pemenuhan Kebutuhan Cabai Tingkat Rumah Tangga di Bogor dan Jakarta (Impact of Chilli Planting Program n Chilli Self Sufficiency at Household Level in Bogor and Jakarta)
Program Gerakan Tanam Cabai (Gertam Cabai) dilatarbelakangi oleh fluktuasi harga cabai yang berlangsung tiap tahun. Program ini bertujuan membantu penyediaan cabai secara berkelanjutan pada tingkat rumah tangga. Penelitian bertujuan untuk mengkaji sejauh mana pengaruh Gertam Cabai terhadap kemandirian pemenuhan kebutuhan cabai tingkat rumah tangga di Kota Bogor dan Jakarta. Metode analisis yang digunakan adalah statistik deskriptif dan impact analysis. Pada metode impact analysis dilakukan pengukuran nilai indikator sebelum dan setelah intervensi program pada dua kelompok, yaitu kelompok yang mendapat intervensi program (Kelompok Aksi) dan kelompok yang tidak mendapat intervensi program (Kelompok Kontrol). Pada masing-masing kelompok dilakukan penghitungan selisih nilai indikator pada saat impact dan baseline. Hasil penelitian menunjukkan bahwa program Gertam Cabai belum memberikan pengaruh terhadap pemenuhan kebutuhan cabai tingkat rumah tangga. Hal ini terlihat dari: (1) tidak adanya perbedaan volume pembelian cabai antara sebelum dan sesudah Gertam Cabai pada kelompok penerima, dan (2) tidak adanya perbedaan volume pembelian cabai sesudah periode program tersebut antara kelompok penerima dan non penerima. Hal ini disebabkan karena banyak tanaman cabai yang mati, cabai yang dibagikan tidak sesuai dengan preferensi konsumen, dan cabai merupakan komoditas yang bersifat inelastis. Terdapat beberapa hal yang perlu diperhatikan apabila program itu masih akan dilaksanakan, yaitu: (1) jenis cabai dalam program itu agar disesuaikan dengan preferensi konsumen, dan (2) pembangunan sistem dan tatanan kelembagaan untuk memastikan keberlanjutan program meliputi sistem pembagian benih, penentuan kelompok penerima, pendampingan pra dan pasca pembagian benih, serta pembekalan teknis budidaya kepada kelompok penerima.KeywordsGerakan tanam cabai; Rumah tangga; Impact analysisAbstract Chilli planting program was motivated by the fluctuation of chili price every year. The objective of this program was to assist the household level for having sustainable supply of chilli. The purpose of this study was to analyze the influence of chilli Planting Program on the self sufficiency of household chilli needs in Bogor and Jakarta. The method of analysis used is descriptive statistics and impact analysis. In the impact analysis method, the indicator measurement before and after the program intervention was done in two groups: the group receiving the program (Action Group) and the group that did not participate in the program (Control Group). The next step is to calculate the difference between the indicators value at impact and baseline on each group. The results showed that chilli planting program has not affected chilli self sufficiency at household level. This can be seen from: (1) there is no difference in the volume of chilli purchasing before and after chilli planting program in the action group, and (2) there is no difference in the volume of chilli purchasing after chilli planting program period between action and control group. This is because a lot of chilli plants were dead, the chili was distributed not in accordance with consumer preferences, and chilli is an inelastic commodity. Some suggestions that should be considered if there is a continuation of the chilli planting program are (1) distributed chilli type has to satisfy household preferences, and (2) the program should be equipped by simultaneous development of system and institutional arrangement to ensure its sustainability, includes a system for distributing seeds, determining beneficiary groups, providing pre and post seed distribution, and providing technical training to the recipient groups.
