Sifat Fisik Dan Komponen Kimia Bunga Melati Jasminum Officinale
Full text linkJasminum officinale from Purbalingga (Central Java) was harvested at three stages of maturity: M-1, M-2, and full bloming. Physical and chemical characteristics were determined by weight of flower, size of flower, aroma, and chemical content. Flowers harvested at stage maturity of M-2: colour of cepal was dark violet, there was no aroma, and flowers did not open. At maturity stage of M-1: optimal flower in size, colour of sepal was soft violet, flowers were fully opened, and had aromatic flavor. The maturity stage of M-1 is very useful in selecting flowers for tea industry or essential oil industry. The opened flowers was useful only for spread flower. Dominant component of aromatic flavors was benzil acetat (46.8%) and followed by methyl salisilat (24.4%), Z. jasmone (20.2%), lynalol (2.9%), neurol idol (2.7%), dan indole (1.7%)
KERAGAMAN GENETIK CUCUMBER MOSAIC VIRUS ASAL TANAMAN TAPAK DARA, NILAM, KARUK, MELATI, DAN KUMIS KUCING
Full text linkCucumber mosaic virus (CMV) symptoms are found in Catharanthus roseus, patchouly (Pogostemon cablin), cubeb (Piper chaba), Jasminum sambac and Java-tea (Orthosiphon aristatus); however, their genetic characterization has not been studied. The study aimed to molecularly characterize the CMV isolates from Catharanthus roseus, patchouly, cubeb, Jasminum sambac and Java-tea. Disease plant samples showing mosaic and yellow mosaic symptoms were collected from Petak Pamer Garden, ISMCRI, Bogor. Molecular characterization was carried out by reverse transcription-polymerase chain reaction (RT-PCR) assay using a specific primer of CMV coat protein gene and DNA sequenced. Sequence analysis was performed using the BLAST, Bioedit, Genedoc, Mega 5 programs. The RT-PCR technique succeeded in amplifying a DNA band measuring 650 bp, according to the prediction of the primary design. BLAST analyses revealed that all of these CMV isolates belonged to subgroup IB. Nucleotide sequence homology of CMV from C. roseus, patchouly, P. chaba, and J. sambac, were more than 95.00%. Based on the phylogenetic tree, these four isolates were closely related to CMV isolate from Japan (AB070622). Homology of the nucleotide sequence of CMV from Java-tea with the other four isolates was below 95.00%. This isolate clustered with CMV isolate from Indonesia (AB042294) and was separated with another four isolates according to the phylogeny tree. In the amino acid sequence alignment, Java-tea isolates had five different amino acids compared to the other four isolates. This result indicates the possibility of CMV transmission between patchouly, Java-tea, C. roseus and J. sambac, so it must be anticipated to prevent its spread. Gejala infeksi Cucumber mosaic virus (CMV) ditemukan pada tanaman tapak dara (Catharanthus roseus), nilam (Pogostemon cablin), karuk (Piper chaba), melati (Jasminum sambac), dan kumis kucing (Orthosiphon aristatus), tetapi karakteristik genetiknya belum diketahui. Tujuan penelitian adalah mengarakterisasi secara molekuler isolat CMV dari tapak dara, nilam, karuk, melati, dan kumis kucing. Sampel tanaman sakit yang menunjukkan gejala mosaik dan mosaik kuning diambil dari Kebun Petak Pamer, Balittro, Bogor. Deteksi molekuler dilakukan secara reverse transcription polymerase chain reaction (RT-PCR) menggunakan primer spesifik yang mengamplifikasi bagian selubung protein CMV. Konfirmasi hasil RT-PCR dilakukan secara sikuensing. Analisis sikuen dilakukan menggunakan program BLAST, Bioedit, Genedoc dan Mega X. Teknik RT-PCR berhasil mengamplifikasi pita DNA berukuran 650 pb, sesuai prediksi desain primer. Hasil analisis BLAST menunjukkan bahwa seluruh isolat merupakan CMV subgroup IB. Sikuen nukleotida isolat CMV asal tapak dara, karuk, nilam dan melati memiliki homologi > 95%, dan berdasarkan analisis filogeni, keempat isolat tersebut dekat dengan isolat CMV dari Jepang (AB070622). Homologi sikuen nukleotida isolat CMV asal kumis kucing sebesar < 95% dibandingkan empat isolat CMV lain. Berdasarkan pohon filogeni, isolat tersebut dekat dengan isolat CMV asal Indonesia (AB042294), terpisah dengan empat isolat lain. Pada pensejajaran runutan asam amino, isolat kumis kucing memiliki lima perbedaan asam amino dibandingkan empat isolat lainnya. Hasil penelitian mengindikasikan bahwa potensi penularan CMV antara tanaman nilam, kumis kucing, tapak dara, dan melati sangat memungkinkan sehingga harus diantisipasi pencegahan penyebarannya
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.

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

Full text linkTurmeric development to fulfil market demand as raw material for herbal industry requires qualified planting material in adequate quantities. This study aimed to evaluate the effect of varieties and seeds type of turmeric to the seeds efficiency, seeds viability, plant performance and rhizome yield. This experiment was conducted at the greenhouse of Indonesian Spices and Medicinal Crops Research Institute (ISMCRI), Bogor and Cicurug Research Installation, Sukabumi from November 2016 to July 2017. The study was arranged in split plot with 3 replications. The main plot was three varieties of turmeric: Curdonia, Turina 2 and Turina 3. The subplot was eight types of seeds-rhizome: (a) single finger rhizome, (b) finger rhizome with one branch, (c) finger rhizome with >1 branches, (d) mother rhizome split 2 horizontally, (e) mother rhizome split 2 vertically, (f) mother rhizome split 4 horizontally, (g) mother rhizome split 4 vertically and (h) whole mother rhizome. Parameters measured were seeds viability, growth and rhizomes yield. Seeds efficiency of Curdonia and Turina 2 can be achieved by using finger rhizome of about 0.49 t.ha-1 for both varieties, rhizome yields of 6.63 t.ha-1 and 11.45 t.ha-1 respectively. Another alternative were the use of 0.47 t.ha-1 mother rhizome split 4 vertically, yielding 9.65 t.ha-1 and 14.20 t.ha-1 fresh rhizome for Curdonia and Turina 2 varieties, consecutively. However, for Turina 3 variety, the seeds efficiency was shown by using mother rhizome split 4 horizontally of 0.66 t.ha1 and yielding fresh rhizome of 17.44 t.ha-1.
