Pengelompokan Plasma Nutfah Rambutan Berdasarkan Karakter Morfologi
Full text linkRambutan is a fruit native to Indonesia, which has a high diversity. Indonesian Tropical Fruit Research Institute has a rambutan germplasm collection. The objectives of the research were to identify and classify rambutan germplasm accessions based on morphological characteristics, in order to identify the specific characteristics important for the development of future varieties of rambutan. Collecting data on the 32 accession was conducted in Aripan Experimental Field, Indonesian Tropical Fruit Research Institute from September 2014 to February 2015. Characterization of morphology characters referred to as the Descriptor for Rambutan was published by IPGRI. Cluster analysis based on morphological characteristics successfully separated the accession of rambutan R7 and R11 with 30 other rambutan accessions with the dissimilarity coefficient of 45%. Accession R4 was similar to Sitangkue, R14 was similar to Korong Gadang, and R15 was similar to Sinyonya. Characteristics that can be used to distinguish each of the accession of rambutan were the width of seed, seed thickness, total soluble solids (TSS), fruit diameter, spintern texture and the spintern color. Accession R15 can be developed as a commercial variety, because it has a high yield, and shelf life associated with high fruit weight characteristics and thick rind
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

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
Pengaruh Asam Salisilat dan K2HPO4 Pada Ketahanan Tanaman Kentang Terhadap Penyakit Busuk Daun di Musim Penghujan (The Effect of Salicylic Acid and K2HPO4 on the Resistance of Potato Plant to Late Blight in Rainy Season)
Full text linkKentang merupakan tanaman pangan bernilai ekonomi tinggi yang rentan terhadap serangan busuk daun (Phytophthora infestans) pada musim penghujan. Penggunaan pestisida sintetik hasilnya belum memuaskan sehingga perlu dilakukan induksi ketahanan terhadap serangan penyakit. Tujuan penelitian untuk mengetahui pengaruh pemberian asam salisilat dan K2HPO4 dalam meningkatkan ketahanan tanaman kentang pada musim penghujan terhadap penyakit busuk daun. Penelitian dilakukan di Kebun Percobaan Berastagi pada ketinggian tempat 1.340 m dpl. pada bulan September sampai dengan Desember 2015. Tata letak percobaan disusun berdasarkan rancangan acak kelompok dua faktor dengan tiga ulangan dan 18 kombinasi perlakuan. Faktor pertama adalah dosis asam salisilat (a0 = 0, a1 = 0,1g/L, a2 = 0,2 g/L, a3 = 0,3 g/L, a4 = 0,4 g/L, dan a5 = 0,2 g/L propineb). Faktor kedua adalah dosis K2HPO4 (k0 = kontrol, k1 = 0,1 g/L, k2 = 0,2 g/L). Hasil penelitian menunjukkan bahwa kombinasi perlakuan 0,1 g/L asam salisilat dan 0,1 g/L K2HPO4 merupakan perlakuan terbaik menurunkan intensitas penyakit P. infestans dan kerusakan umbi kentang. Intensitas penyakit sampai 9 minggu setelah aplikasi hanya 7,46%, sedangkan kerusakan umbi hanya sebesar 0,35%. Jumlah umbi dan persentase kelas umbi per tanaman hanya dipengaruhi oleh K2HPO4, sedangkan bobot umbi tidak dipengaruhi kedua perlakuan. KeywordsKentang; Asam salisilat; K2HPO4; Ketahanan; Musim penghujanAbstractPotatoes are high economic value crops that are vulnerable to the attack of late blight (Phytophthora infestans) in the rainy season. The use of synthetic pesticides has not been satisfactory, so that should be induced for the disease resistance. The objective of the research was to determine the giving effect of salicylic acid and K2HPO4 in improving the resilience of the potato crop in the rainy season to late blight. The study was conducted at Berastagi Experimental Garden in altitude 1,340 meters above sea level, from September to December 2015. The layout of the trial is based on two factor randomized complete block design with three replications and 18 combination treatments. The first factor is the dose of salicylic acid (A0 = 0, A1 = 0,1g/L, A2 = 0,2 g/L, A3 = 0,3 g/L, A4 = 0,4 g/L and A5 = 0,2 g/L propineb), the second factor is the dose K 2HPO4 (K0 = control, K1 = 0.1 g/L, K2 = 0.2 g / L). The results showed that the combination treatment of 0.1 g/L of salicylic acid and 0,1 g/L K2HPO4 is the best treatment because it can reduce the intensity of the Phytophthora infestans disease and potato tuber damage. The disease intensity up to 9 weeks after application only 7.46%, while the tuber damage only 0.35%. The number and percentage of class tubers per plant only affected by K2HPO4, while the tuber weight was not influenced both treatments
