Level Model

Pelevelan model mental merupakan salah satu cara untuk melihat sejauh mana pemahaman siswa yang didasarkan pada tingkatan masing-masing level. Menurut pendapat para ahli tidak dapat dikesampingkan bahwa level pemahaman masing-masing siswa tentunya berbeda-beda, mulai dari tingkatan rendah, menengah, hingga tingkat atas dan pelevelan pemahaman siswa itu sendiri dapat diukur dengan berbagai hal, salah satunya adalah model mental. Model mental bisa digunakan untuk mengetahui tingkat pemahaman siswa dan menunjukkan cara berpikir siswa. Tujuan penelitian ini adalah untuk mendeskripsikan enam level model mental siswa kelas VIII dalam memahami konsep persamaan garis lurus. Metode yang digunakan peneliti dalam penelitian ini adalah metode penelitian kualitatif. Subjek dalam penelitian ini adalah siswa kelas VIII dengan jumlah 121 siswa, subjek tersebut diambil agar terpenuhi masing-masing level model mental. Kemudian diambil 2 siswa untuk diwawancarai sebagai subjek terpilih yang menjadi perwakilan masing-masing level model mental. Sehingga diperoleh 12 siswa sebagai subjek wawancara. Instrumen dalam penelitian ini meliputi soal tes dan pedoman wawancara yang sebelumnya divallidasi. Prosedur pengumpulan data yaitu dengan observasi, tes, wawancara, serta dokumentasi. Peneliti menganalisis data dengan dua cara, yaitu triangulasi sumber data dan triangulasi metode untuk memastikan kevalidan data. Sehingga diperoleh hasil penelitian yang menunjukkan deskripsi masing-masing level model mental siswa dalam memahami konsep persamaan garis lurus.

Pythagoras Theorem

A domain of learning, understanding is an absolute prerequisite for improving cognitive abilities. Leveling the mental model of students is one way in which a teacher can review the extent to which students understand based on their respective levels. The purpose of this study was to describe the six degrees of student's mental models in understanding the concept of using the Pythagoras theorem in junior high school students. The method used in this study is a qualitative research method. The subjects in this study amounted to 61 students who were a combination of 30 students of class VIII A and 31 students of class VIII B. The two classes of subjects were taken so that the six levels of the mental model were founded. The sixty-one items test questions were given. Each of the representatives of mental models who found the criteria was selected, namely two students to be interviewed so that 12 students were interview respondents. To ensure the validity of the data, researchers analyzed the data in two ways, namely data source triangulation and method triangulation. The results of the study showed a description of each level of the student's mental model in understanding the concept of using the Pythagoras theorem.   Suatudomain belajar, pemahaman merupakan prasyaratan mutlak untuk meningkatkankemampuankognitif.  Pelevelan model mental siswa merupakan salah satu cara dimana seorang pengajar dapat meninjau sejauh manakah pemahaman siswa berdasarkan tingkatan masing – masing.

This study aims to obtain a description of the supporting and inhibiting factors in the process of organizational change of education based on management perspective that occurs in the scope of higher health education of the Ministry of Health of the Republic of Indonesia. This study used a qualitative approach by conducting case study at Palangka Raya Health Polytechnic. The research results are as follows: (a) Supporting factor that must be there is the existence of a manual or technical guidance in organizing the organization; (b) Whereas the inhibiting factor is the old habits, the mindset, the mental model is still inhibiting from the organizers and members of the organization; (c) The inhibiting factor is the existence of selfishness of each highly visible party; (d) Inhibitors may also occur if there are still "little kings" and selfishness from each of the former institutions; (e) Other issues that support in this process of change are in terms of facilities and infrastructure, namely the availability of buildings and land; (f) Another inhibiting factor is that in terms of educational qualifications, there are departments that do not meet, for example in the midwifery department there are still many average teachers with Diploma IV education background and non-linear education; (g) Inhibiting factors may also occur if the reason of seniority is always carried around; (h) The inhibiting factor is lack of human resources in using modern health equipment, including the use of teaching aids in accordance with the progress of science and teaching and learning technology.   Penelitian ini bertujuan untuk memperolah gambaran mengenai faktor pendukung dan penghambat dalam proses perubahan organisasi pendidikan yang ditinjau dari perspektif manajemen yang terjadi di lingkup organisasi pendidikan tinggi kesehatan Kementerian Kesehatan Republik Indonesia. Penelitian ini menggunakan pendekatan kualitatif dengan melakukan studi kasus pada institusi Politeknik Kesehatan Kemenkes Palangka Raya. Hasil penelitian adalah sebagai berikut: (a) Faktor pendukung yang harus ada yaitu adanya buku pedoman atau petunjuk teknis dalam penyelenggaraan organisasi; (b) Sedangkan yang menjadi faktor penghambat itu adalah kebiasaan lama, mindset-nya, mental model-nya masih bersifat menghambat dari para pengelola dan anggota organisasi; (c) Faktor penghambat yaitu adanya keegoisan masing-masing pihak yang sangat tampak; (d) Penghambat juga dapat terjadi apabila masih ada “raja-raja kecil” dan keegoisan dari masing-masing institusi yang dulu; (e) Perihal lain yang mendukung dalam proses perubahan ini adalah dari sisi sarana dan prasarana, yaitu tersedianya gedung dan tanah; (f) Faktor penghambat lain yaitu dari sisi kualifikasi pendidikan ternyata ada jurusan yang tidak memenuhi, misalnya di jurusan kebidanan masih banyak rata-rata tenaga pengajar dengan latar pendidikan Diploma IV dan pendidikannya tidak linear; (g) Faktor penghambat juga dapat terjadi apabila alasan senioritas selalu dibawa-bawa; (h) Faktor penghambat yaitu masih kurang kesiapan sumber daya manusia dalam menggunakan alat-alat kesehatan modern termasuk penggunaan alat bantu belajar mengajar yang sesuai dengan kemajuan ilmu pengetahuan dan teknologi pengajaran dan pembelajaran.

Time Resolved Photoluminescence

Time-resolved photoluminescence spectra have been recorded on three GaN epitaxial layers of thickness 2.5 μm, 7 μm and 16 μm, at various temperatures ranging from 8K to 300K. The layers were deposited by MOVPE on (0001) sapphire substrates with standard AlN buffer layers. To achieve good homogeneities, the growth was in-situ monitored by laser reflectometry. All GaN layers showed sharp excitonic peaks in cw PL and three excitonic contributions were seen by reflectivity. The recombination dynamics of excitons depends strongly upon the layer thickness. For the thinnest layer, exponential decays with τ ~ 35 ps have been measured for both XA and XB free excitons. For the thickest layer, the decay becomes biexponential with τ1 ~ 80 ps and τ2 ~ 250 ps. These values are preserved up to room temperature. By solving coupled rate equations in a four-level model, this evolution is interpreted in terms of the reduction of density of both shallow impurities and deep traps, versus layer thickness, roughly following a L−1 law.

Abstract Nowadays, the growth and complexity of functionalities of current information systems, especially dynamic, distributed and heterogeneous information systems, makes the design and creation of such systems a difficult task and at the same time, strategic for businesses. A very important stage of data protection in an information system is the creation of a high level model, independent of the software, satisfying the needs of system protection and security. The process of role engineering, i.e. the identification of roles and setting up in an organization is a complex task. The paper presents the modeling and design stages in the process of role engineering in the aspect of security schema development for information systems, in particular for dynamic, distributed information systems, based on the role concept and the usage concept. Such a schema is created first of all during the design phase of a system. Two actors should cooperate with each other in this creation process, the application developer and the security administrator, to determine the minimal set of user’s roles in agreement with the security constraints that guarantee the global security coherence of the system.
