HUBUNGAN ANTARA KOMITMEN BERPACARAN DENGAN KUALITAS PERSAHABATAN PADA REMAJA AKHIR DI UNIVERSITAS PENDIDIKAN INDONESIA

Penelitian ini memiliki beberapa tujuan, yaitu untuk mengetahui (1) gambaran komitmen berpacaran, (2) gambaran kualitas persahabatan, (3) hubungan antara komitmen berpacaran dengan kualitas persahabatan pada remaja akhir di Universitas Pendidikan Indonesia (UPI). Responden pada penelitian ini ialah mahasiswa di UPI yang berada pada usia remaja akhir yang memiliki pasangan (pacar) dan juga teman dekat (sahabat). Terdapat 200 orang responden sesuai kriteria yang telah ditentukan dalam penelitian ini. Penelitian ini menggunakan metode kuantitatif dan menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui penyebaran kuesioner dengan memanfaatkan aplikasi google docs. Kuesioner berisikan skala komitmen berpacaran yang peneliti adaptasi dan modifikasi dari Commitment Measurenment milik Rusbult (1983) dan skala kualitas persahabatan yang juga peneliti adaptasi dan modifikasi dari Friendship Quality Scale (FQS) milik Bukowski, Hoza, dan Bovin (Ponti, dkk, 2010). Data yang diperoleh dianalisis menggunakan teknik korelasi Spearman Rho. Hasil penelitian menunjukkan (1) remaja akhir di UPI memiliki komitmen berpacaran yang cenderung rendah yaitu sebanyak 41% dari 200 orang responden, (2) remaja akhir di UPI memiliki kualitas persahabatan yang cenderung rendah yaitu sebanyak 36,5% dari 200 orang responden, dan (3) terdapat hubungan yang antara komitmen berpacaran dengan kualitas persahabatan pada remaja akhir di Universitas Pendidikan Indonesia.---------This study aims to describe (1) the image of commitment dating (2) the big picture of quality of friendship, and (3) relationship between Commitment Dating with the quality of friendship late adolescence at Indonesia University of Education (UPI). Responders of this study are late adolescence at Indonesia University of Education who are in commitment relationship and having close friends. There are around 200 people with the appropriate criteria have been determined in this study. This study uses quantitative methods and using purposive sampling technique. Data collected through questionnaires by using google docs app. The questionnaire contains of a commitment dating scale that is adapted by researcher and modification of Commitment Measurenment owned by Rusbult (1983) and so is Quality Scale (FQS) belongs to Bukowski, Hoza, and Bovin (Ponti et al, 2010). Data was analyzed by using Spearman Rho correlation techniques. The result showed that (1) late adolescence of UPI who are in committed relationship that tends to lower as many as 41% of the 200 respondents, (2) late adolescence of UPI have a rather low quality friendships as many as 36.5% of the 200 respondents, and (3) there is a relationship between commitment dating with the quality of friendship in late teens at UPI

First fabrication of full 3D-detectors at SINTEF

International audienceA knowledge of the mechanical properties of bacterial biofilms is required to more fully understand the processes of biofilm formation such as initial adhesion or detachment. The main contribution of this article is to demonstrate the use of homogenization techniques to compute mechanical parameters of Pseudomonas aeruginosa PAO1 biofilms. For this purpose, homogenization techniques are used to analyze freeze substitution electron micrographs of the biofilm cross-sections. The concept of a representative volume element and the study about his representativeness allows us to determine the optimal size in order to analyze these biofilm images. Results demonstrate significant heterogeneities with respect to stiffness and these can be explained by varying cell density distribution throughout the bacterial biofilms. These stiffness variations lead to different mechanical properties along the height of the biofilm. Moreover, a numerical shear stress test shows the impact of these heterogeneities on the detachment process. Several modes of detachment are highlighted according to the local strain energy in the different parts of the biofilm. Knowing where, and how, a biofilm may detach will allow better prediction of accumulation and biomass detachment

Characterization of boron-coated silicon sensors for thermal neutron detection

Silicon neutron detectors can operate at low voltage and come with ease of fabrication and the possibility of integration of readout electronics and thus are attractive from an application point of view. In this paper, we have studied thermal neutron capture by silicon diodes coated with boron carbide (B4C). One of the surfaces of the diodes was covered with either natural B4C (B4C) or with enriched B4C (B4C). We have investigated: (a) the effect of increase in the sensitive area of the surface of the diode covered with B4C on the neutron detection efficiency and (b) the effect of enrichment of 10B in B4C. The difference in 10B in B4C (16 at.% in the deposited film) and B4C ( 79 at.% in the deposited film) leads to about three times increase in detection efficiency of the same detector. For the given experimental conditions, we do not observe a direct relationship between increase in the surface area and the detection efficiency. Energy spectra obtained by Geant4 simulations support the experimental observation of finding no direct relation between increase in the surface area and the detection efficiency.publishedVersio

Dynamics of magnetization at infinite temperature in a Heisenberg spin chain

Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin dynamics of the 1D Heisenberg model were conjectured to belong to the Kardar-Parisi-Zhang (KPZ) universality class based on the scaling of the infinite-temperature spin-spin correlation function. In a chain of 46 superconducting qubits, we study the probability distribution, $P(\mathcal{M})$, of the magnetization transferred across the chain's center. The first two moments of $P(\mathcal{M})$ show superdiffusive behavior, a hallmark of KPZ universality. However, the third and fourth moments rule out the KPZ conjecture and allow for evaluating other theories. Our results highlight the importance of studying higher moments in determining dynamic universality classes and provide key insights into universal behavior in quantum systems
