Faktor – Faktor Yang Berhubungan Perilaku Merokok Pada Remaja di SMA YP PGRI 2 Kota Makassar

Perilaku merokok saat ini tidak hanya melanda orang dewasa, melainkan juga melanda remaja. Data Global Youth Tobacco tahun 2019, menunjukkan bahwa 40,6% pelajar di Indonesia (usia 13-15 tahun) sudah pernah menggunakan produk tembakau. Tujuan Penelitian ini untuk mengetahui faktor–faktor yang berhubungan perilaku merokok pada remaja di SMA YP PGRI 2 Kota Makassar. Menggunakan metode analitik observasional desain Cross Sectional Study” dengan jumlah responden sebanyak 51 orang. Metode penarikan sampel yang digunakan yaitu simple random sampling dan pengumpulan data menggunakan kuisioner. Hasil penelitian menunjukkan bahwa terdapat hubungan yang signifikan antara pengetahuan (p value=0,013), teman sebaya (p value=0,000), dan iklan rokok (p value=0,007) dengan perilaku merokok pada remaja di SMA YP PGRI 2 Kota Makassar

Evolutionary relationships between yeast and bacterial homoserine dehydrogenases

AbstractThe Saccharomyces cerevisiae HOM6 gene, encoding homoserine dehydrogenase (EC 1.1.1.3) was cloned and its nucleotide sequence determined. The yeast homoserine dehydrogenase shows extensive homology to the homoserine dehydrogenase domains of the two aspartokinase-homoserine dehydrogenases from Escherichia coli as well as to the homoserine dehydrogenases from Gram positive bacteria. Sequence alignment reveals that the yeast enzyme is the smallest homoserine dehydrogenase known, owing to the absence of a C-terminal domain endowed with the l-threonine allosteric response in Gram positive bacteria. Accordingly, the S. cerevisiae enzyme appears to be a naturally occurring feedback resistant homoserine dehydrogenase. Our results indicate that homoserine dehydrogenase was originally an unregulated enzyme and that feedback control acquisition occured twice during evolution after the divergence between Gram positive and Gram negative bacteria

ANALISIS KELAYAKAN IMPLEMENTASI E-GOVERNMENT DALAM PELAYANAN PUBLIK DI BIDANG KEAGRARIAAN DI KABUPATEN PINRANG

This study aims to (1) determine the readiness of the Organization Land Office Pinrang against regulations that support the implementation of e-government dala (2) determine the readiness of Human Resources at the District Land Office Pinrang apparat of the knowledge and skills in the implementation of e-government (3) knowing Infrastructure support at the District Land Office Pinrang in terms of hardware and software for e-government implementation. This study was conducted in Pinrang District Land Office, in April to July 2015. The informant is taken apparatus using the CTF application service counter and apparat part survey, measurement and mapping using ArcGIS software. Data collection method is a questionnaire, interview, observation and documentation. Data were analyzed using simple frequency table. These results indicate that the feasibility of the implementation of e- government at the District Land Office Pinrang not optimal, this is due to the organization of the District Land Office Pinrang not supported by the local government regulation on the implementation of e-government readiness in detail although Human Resources supports and readiness Infrastructure adequate.  Penelitian ini bertujuan untuk (1) mengetahui kesiapan Organisasi Kantor Pertanahan Kabupaten Pinrang terhadap peraturan yang mendukung dala penerapan e-government (2) mengetahui kesiapan Sumber Daya Manusia pada Kantor Pertanahan Kabupaten Pinrang terhadap pengetahuan dan keterampilan apparat dalam penerapan e- government (3) mengetahui dukungan Infrastruktur pada Kantor Pertanahan Kabupaten Pinrang dalam hal hardware dan software untuk penerapan e-government. Penelitian ini dilaksanakan di Kantor Pertanahan Kabupaten Pinrang, pada bulan april sampai bulan Juli 2015. Informan yang diambil adalah aparat yang menggunakan aplikasi KKP pada loket pelayanan dan apparat bagian Survei, Pengukuran dan Pemetaan yang menggunakan software ArcGIS. Metode pengumpulan datanya adalah kuesioner, wawancara, observasi dan dokumentasi. Data dianalisis secara sederhana dengan menggunakan tabel frekuensi. Hasil penelitian ini menunjukkan bahwa kelayakan implementasi e- government pada Kantor Pertanahan Kabupaten Pinrang belum optimal, hal ini disebabkan dalam organisasi Kantor Pertanahan Kabupaten Pinrang belum didukung adanya peraturan pemerintah daerah tentang penerapan e- government secara rinci walaupun kesiapan Sumber Daya Manusia sudah mendukung serta kesiapan Infrastruktur telah memadai.

Some Systematics of Galactic Globular Clusters

The global properties of all known Galactic globular clusters are examined. The relationship between the luminosities and the metallicities of Galactic globular clusters is found to be complex. Among luminous clusters there is a correlation in the sense that the oldest clusters are slightly more metal deficient than are younger clusters. However, no such clear-cut relationship is found among the faintest globular clusters. The central concentration index C of globular clusters is seen to be independent of metallicity. The dependence of the half-light radii of globular clusters on their Galactocentric distances can be approximated by the relation $R_h \alpha R^{2/3}_{gc}$. Clusters with collapsed cores are mostly situated close to the Galactic nucleus. For $R_{gc} < 10$ kpc the luminosities and the radii of clusters appear to be uncorrelated. The Galaxy differs from the LMC and the SMC in that it appears to lack highly flattened luminous clusters. Galactic globular clusters with ages $\geq$ 13.0 Gyr are all of Oosterhoff type II, whereas almost all of those with ages $<$ 13.0 Gyr have been assigned to Oosterhoff type I. Globular clusters with ages $<$11.5 Gyr are all located in the outer Galactic halo, have below-average luminosities and above-average radii. On the other hand the very old globular cluster NGC 6522 is situated close to the Galactic nucleus.Comment: PASP, in pres

Resolving Globular Cluster Formation within a Cosmological Context

We place constraints on the formation redshifts for blue globular clusters (BGCs), independent of the details of hydrodynamics and population III star formation. The observed radial distribution of BGCs in the Milky Way Galaxy suggests that they formed in biased dark matter halos at high redshift. As a result, simulations of a ~1 Mpc box up to z~10 must resolve BGC formation in LCDM. We find that most halo stars could be produced from destroyed BGCs and other low-mass clusters that formed at high redshift. We present a proof-of-concept simulation that captures the formation of globular-like star clusters.Comment: Accepted for publication in ApJ

Galactic bulge formation as a maximum intensity starburst

Properties of normal galactic star formation, including the density dependence, threshold density, turbulent scaling relations, and clustering properties, are applied to the formation of galactic bulges. One important difference is that the bulge potential well is too deep to have allowed self-regulation or blow-out by the pressures from young stars, unlike galactic disks or dwarf galaxies. As a result, bulge formation should have been at the maximum rate, which is such that most of the gas would get converted into stars in only a few dynamical time scales, or ~10^8 years. The gas accretion phase can be longer than this, but once the critical density is reached, which depends primarily on the total virial density from dark matter, the formation of stars in the bulge should have been extremely rapid. Such three-dimensional star formation should also have formed many clusters, like normal disk star formation today. Some of these clusters may have survived as old globulars, but most got dispersed, although they might still be observable as concentrated streams in phase space.Comment: 10 pages, 1 figure, scheduled for ApJ, vol. 517, May 20, 199

Temperature-dependent magnetospectroscopy of HgTe quantum wells

We report on magnetospectroscopy of HgTe quantum wells in magnetic fields up to 45 T in temperature range from 4.2 K up to 185 K. We observe intra- and inter-band transitions from zero-mode Landau levels, which split from the bottom conduction and upper valence subbands, and merge under the applied magnetic field. To describe experimental results, realistic temperature-dependent calculations of Landau levels have been performed. We show that although our samples are topological insulators at low temperatures only, the signature of such phase persists in optical transitions at high temperatures and high magnetic fields. Our results demonstrate that temperature-dependent magnetospectroscopy is a powerful tool to discriminate trivial and topological insulator phases in HgTe quantum wells
