Besar Ijen 77 C, Malang 651121e-mail : 1)[email protected] pada usia sekolah dasar yang mengalami penurunan prestasi belajar perlu untuk dideteksi kesehatan jiwanya, di SDN Bumiaji 02 Kota Batu tidak mempunyai guru BP, serta guru kelas dan guru penjas yang secara khusus menangani kebutuhan kesehatan jiwa maupun mental anak. Jenis Penelitian adalah Deskriptif. Penelitian ini bertujuan untuk mengidentifikasi kesehatan jiwa pada anak usia sekolah dasar yang mengalami penurunan prestasi belajar melalui deteksi dini di SDN Bumiaji 02 Kota Batu, dilaksanakan pada tanggal 3-4 Februari 2014. Populasi dalam penelitian ini adalah orang tua anak di SDN Bumiaji 02 Kota Batu yang mengalami penurunan prastasi belajar selama 3 semester terakhir dengan jumlah sampel 31 responden, menggunakan teknik total sampling dan teknik pengumpulan data menggunakan Pediatric Symptom Checklist (PSC). Hasil penelitian menunjukkan bahwa sebagian besar atau 23 responden (74%) kemungkinan bermasalah kesehatan jiwanya tetapi tidak perlu dilakukan pemeriksaan lebih lanjut dan sebagian kecil atau 8 responden (26%) kemungkinan bermasalah dan perlu dilakukan pemeriksaan lebih lanjut. Oleh karena itu orang tua dan guru harus lebih memperhatikan pertumbuhan dan perkembangan anak khususnya kesehatan jiwa bagi anak yang mengalami penurunan prestasi belajar.Kata kunci : Prestasi belajar, Kesehatan jiwa, Anak, Usia sekolah dasarABSTRACTChildren at primary school age decreased learning achievement needs to be detected the health of his soul, in elementary school Bumiaji 2 Batu City does not have BP teachers and PE teachers that specifically adress the needs of children's mental health and mental. This study aims to identify mental health in primary school age children who experience a decrease in learning achievement through early detection in Elementary School Bumiaji 02 Sub-Distric Of Bumiaji, held on 3-4 February, 2014. The population in this study is the parents of children at SDN Bumiaji 02 Batu City decreased learning achievement during the last 3 semesters with a sample of 31 responden, using total sampling and technique propotionate and data collection techniques using sheet Pediatric Symptom Checklist (PSC). The result showed that the majority or 23 respondents (74%) the possibility of mental health problem but do not need to do further test and a small portion or 8 respondents (26%) could be a problem and need to do further test. Sugest for parents and teachers should pay more attention to the growth and development of mental health for child that decreased learning achievement

    Quasi-phase matched (QPM) surface emitting second harmonic generation was demonstrated with nonlinear/linear multilayer waveguides in poled polymer based devices. The nonlinear/linear multilayer film was fabricated with a 4-dimethylamino-4\u27-nitrostilbene (DANS) side chain polymer and a cross-linkable clear polymer. Large efficiency improvement was observed with a combination of QPM and strong field parallel poling

    Betel nut palm plant is one of the many benefits and efficacy, especially seeds. Areca nuts are widely used as the main raw material in the process of making drugs, cosmetics, slimming, snacks, sweets, and coffee. Betel nut processing into betel nut is still constrained by the tool is still modest, are still using wood beams repose knife to split betel nut into two parts. To overcome these problems needed betel nut splitter machine with a capacity of 250 kg / h. This engine design is expected to help farmers during the process of betel nut processing into dried betel nut. The working principle of betel nut splitter machine originated from an electric motor that produces rotation is forwarded to the reducer and to the cutting blade associated with two gears. Betel nut is inserted through the insertion funnel towards the rotor has 4 channels / trench, and rotor spinning and crashing betel nut rotating blades reversed so the rotor besidesbetel nut split into two parts. Shaft rotation speed at the eye-piece and carrier rotor shaft is 9.32 rpm, the rotation speed is obtained from the ratio gearbox and pulley on the engine splitter ratio. With the machine is expected to help farmers to cultivate betel nut, so the work is lighter, faster and may prevent accidents.

    We demonstrate second-harmonic generation due to counterpropagating beams in planar waveguides of 2-docosylamino-5-nitropyridine (DCANP). The DCANP molecules were deposited by Langmuir-Blodgett techniques and have a preferred alignment within the substrate plane. Four-layer waveguide structures were used to optimize the trade-off between propagation loss and efficient surface-emitted green light

    On-surface synthesis and characterization of nitrogen-substituted undecacenes

    Heteroatom substitution in acenes allows tailoring of their remarkable electronic properties, expected to include spin-polarization and magnetism for larger members of the acene family. Here, we present a strategy for the on-surface synthesis of three undecacene analogs substituted with four nitrogen atoms on an Au(111) substrate, by employing specifically designed diethano-bridged precursors. A similarly designed precursor is used to synthesize the pristine undecacene molecule. By comparing experimental features of scanning probe microscopy with ab initio simulations, we demonstrate that the ground state of the synthesized tetraazaundecacene has considerable open-shell character on Au(111). Additionally, we demonstrate that the electronegative nitrogen atoms induce a considerable shift in energy level alignment compared to the pristine undecacene, and that the introduction of hydro-aza groups causes local anti-aromaticity in the synthesized compounds. Our work provides access to the precise fabrication of nitrogen-substituted acenes and their analogs, potential building-blocks of organic electronics and spintronics, and a rich playground to explore π-electron correlation

    Crystal Structure of the Formin mDia1 in Autoinhibited Conformation

    Formin proteins utilize a conserved formin homology 2 (FH2) domain to nucleate new actin filaments. In mammalian diaphanous-related formins (DRFs) the FH2 domain is inhibited through an unknown mechanism by intramolecular binding of the diaphanous autoinhibitory domain (DAD) and the diaphanous inhibitory domain (DID).Here we report the crystal structure of a complex between DID and FH2-DAD fragments of the mammalian DRF, mDia1 (mammalian diaphanous 1 also called Drf1 or p140mDia). The structure shows a tetrameric configuration (4 FH2 + 4 DID) in which the actin-binding sites on the FH2 domain are sterically occluded. However biochemical data suggest the full-length mDia1 is a dimer in solution (2 FH2 + 2 DID). Based on the crystal structure, we have generated possible dimer models and found that architectures of all of these models are incompatible with binding to actin filament but not to actin monomer. Furthermore, we show that the minimal functional monomeric unit in the FH2 domain, termed the bridge element, can be inhibited by isolated monomeric DID. NMR data on the bridge-DID system revealed that at least one of the two actin-binding sites on the bridge element is accessible to actin monomer in the inhibited state.Our findings suggest that autoinhibition in the native DRF dimer involves steric hindrance with the actin filament. Although the structure of a full-length DRF would be required for clarification of the presented models, our work here provides the first structural insights into the mechanism of the DRF autoinhibition
