Authors: Utoyo Harry , Sarmili Lili 
Published: October 2018

Endapan pasir besi di Pantai Panggul Trenggalek didominasi oleh mineral-mineral berat yang terdiri dari magnetit (> 70 %), ilmenit, piroksen, horenblenda, zirkon, apatit dan feldspar. Batuan sumber diduga berasal dari batupasir magnetit bagian dari Formasi Jaten serta batuan gunung api Tersier yang banyak tersebar di daerah Trenggalek. Terbentuknya magnetit diduga berasal dari mineralisasi magnetit dari batuan gunung api Formasi Mandalika, seperti yang dijumpai di Ngadipuro, Kecamatan Munjungan. Batuan gunung api Tersier daerah Trenggalek, Jawa-Timur umumnya dibentuk oleh batuan berkomposisi andesitik hingga dasitik, yang berbentuk dyke, stock dan sill, serta berstruktur lava bantal. Analisis petrografi umumnya memperlihatkan tekstur porfiritik, berstruktur aliran dan teralterasi pada tingkatan yang rendah menjadi klorit, karbonat serisit dan epidot.

PENGARUH SEDIMENTASI TERHADAP PENYEBARAN TERUMBU KARANG DI TELUK WONDAMA, PAPUA
Authors: Permanawati Yani , Sarmili Lili 
Published: October 2018

Endapan lumpur yang terdapat di bagian barat teluk Wondama sebarannya sangat sedikit jika dibandingkan di bagian timurnya. Endapan lumpur ini tidak berhubungan langsung dengan hasil erosi sungai baik di bagian barat maupun teluk Wondama tetapi berasal dari bagian selatan teluk yang dibawa oleh arus ke arah utara. Batugamping mendominasi bagian barat teluk Wondama, sedangkan sungai-sungai yang melewati batugamping ini, airnya tentunya akan banyak mengandung unsur karbonat sehingga menjadikan terumbu karang lebih mudah tumbuh di sepanjang pantai bagian Barat dibandingkan bagian Timur teluk Terjaganya kehidupan terumbu karang ini karena lingkungan yang bersih yang juga ditunjang oleh pola kehidupan masyarakat pesisir teluk Wondama yang sadar menjaga keseimbangan alam termasuk para nelayan yang masih menggunakan alat penangkapan ikan tradisional. Kata kunci : Terumbu karang, endapan lumpur, Teluk Wondama The distribution of mud on westernpart of Wondama Bay is very limited compared to its easternpart. The existence of mud is not directly related to the erosion of rivers along its west or east of the bay but it is originated from the south of the bay where current brought the sediment to the north. The limestone is dominated on its westernpart of Wondama bay, whereas rivers those cut the limestone will contain carbonate element and will support the coral reef grows better on its westernpart rather than on its easterpart of the bay. The good reservation of the coral reef is clearly related to clean environment and also supported by human lifes whose can keep and preserve the natural balance, for example, the fisheries are still using a traditional equipment.

Mineral Zirkon sebagai mineral primer umumnya ditemukan pada batuan beku, batugamping kristalin, sekis, dan genes, juga di dalam batuan sedimen sebagai sedimen plaser yang diendapkan di pantai dan di muara sungai. Hasil analisis petrografi dari empat lokasi contoh di teluk Wondama Papua Barat, menunjukan WDM06-20 adalah amfibolit, WDM06-21 adalah mica schist, WDM06-22 adalah amfibolit, dan WDM06-23 adalah schist. Hasil analisis kimia lainnya menunjukan bahwa batuan asal termasuk kedalam batuan yang bersifat siliceous-alkali-calsic rock, sedangkan keterdapatan zirkon di daerah penyelidikan berada di dalam lingkungan batuan metamorf. Hasil ploting tipologi, mineral zirkon yang diambil dari percontohan di sepanjang pantai, termasuk kedalam tipe utama granite terutama berasal dari kerak benua dan berdasarkan populasi dan bentuk kristal termasuk ke dalam (Sub)autochthonous Monzogranit and Granodiorites. Berdasarkan data analisis kimia dan bukti-bukti di lapangan bahwa batuan asal dapat ditafsirkan sebagai batuan bersifat granitik yang telah mengalami proses granitisasi menjadi batuan metamorfik. Kata Kunci : Mineral zirkon, batuan metamorf, granit, Teluk Wondama Papua. A zircon mineral as a primary mineral is generallly formed in the igneous rocks, crystalline limestones, schists, and gneisses also in sedimentary rocks in beaches and rivers as placer deposits. The petrographical analyses from four differents samples shows that WDM 06-20 is amphibolite, WDM 06-21 is micca schist, WDM 06-22 is amphibolite and WDM 06- 23 is schist. From other chemical analyses show that the source rocks belong to siliceous-alkali-calsic rocks whereas the occurrences of zircon minerals in the study area are correlates to metamorphic rocks. On typological evolution trends, zircon minerals from samples taken alongs the shoreline are plotted as granitic rocks of continental crust, and based on their population and crystallographical forms they are in (sub) autochthonous Monzogranite and Granodiorite. Based on data of chemical analyses and fieldworks, the source rock can be interpreted as granitic rocks which have been substituted by granitization process to be metamorphic rocks.

The Enigmatic Compact Radio Source Coincident with the Energetic X-Ray Pulsar PSR J1813–1749 and HESS J1813–178

Abstract
New Very Large Array (VLA) detections of the variable radio continuum source VLA J181335.1−174957, associated with the energetic X-ray pulsar PSR J1813−1749 and the TeV source HESS J1813–178, are presented. The radio source has a right circular polarization of ∼50% and a negative spectral index of −1.3 ± 0.1, which show that it is nonthermal. The radio pulses of the pulsar are not detected from additional Effelsberg observations at 1.4 GHz made within one week of a VLA detection. This result would appear to support the idea that the continuum radio emission detected with the VLA does not trace the time-averaged emission pulses, as had previously been suggested. We discuss other possible origins for the radio source, such as a pulsar wind, magnetospheric emission, and a low-mass star companion. However, observations made at higher frequencies by Camilo et al. show that the VLA source is in fact the time-averaged pulsed emission and that the detection of the pulses had not been achieved because this is the most scattered pulsar known.
Glitch Behavior of Pulsars and Contribution from Neutron Star Crust

Published: October 2018

Abstract
Pulsars are highly magnetized rotating neutron stars (NSs) with a very stable rotation speed. Irrespective of their stable rotation rate, many pulsars have been observed to feature a sudden jump in the spin frequency, known as a pulsar glitch. The glitch phenomena are considered to be an exhibit of superfluidity of neutron matter inside the NS’s crustal region. The magnitude of such a rapid change in rotation rate relative to the stable rotation frequency can quantify the ratio of the moment of inertia (MoI) of the crustal region to the total MoI of the star, also called the fractional moment of inertia (FMI). In this paper, we have calculated the FMI for different masses of a star using six different representative unified equations of state constructed under a relativistic mean field framework. We have performed an event-wise comparison of the FMI obtained from data with that from theoretically calculated values with and without considering the entrainment effect. It is found that larger glitches cannot be explained by the crustal FMI alone, even without entrainment.
The Role of Black Hole Feedback on Size and Structural Evolution in Massive Galaxies

Published: October 2018

Abstract
We use cosmological hydrodynamical simulations to investigate the role of feedback from accreting black holes in the evolution of the size, compactness, stellar core density, and specific star formation of massive galaxies with stellar masses of

. We perform two sets of cosmological zoom-in simulations of 30 halos to z = 0: (1) without black holes and active galactic nucleus (AGN) feedback and (2) with AGN feedback arising from winds and X-ray radiation. We find that AGN feedback can alter the stellar density distribution, reduce the core density within the central 1 kpc by 0.3 dex from z = 1, and enhance the size growth of massive galaxies. We also find that galaxies simulated with AGN feedback evolve along tracks similar to those characterized by observations of specific star formation rate versus compactness. We confirm that AGN feedback plays an important role in transforming galaxies from blue compact galaxies into red extended galaxies in two ways: (1) it effectively quenches the star formation, transforming blue compact galaxies into compact quiescent galaxies, and (2) it also removes and prevents new accretion of cold gas, shutting down in situ star formation and causing subsequent mergers to be gas-poor or mixed. Gas-poor minor mergers then build up an extended stellar envelope. AGN feedback also puffs up the central region through fast AGN-driven winds as well as the slow expulsion of gas while the black hole is quiescent. Without AGN feedback, large amounts of gas accumulate in the central region, triggering star formation and leading to overly massive blue galaxies with dense stellar cores.

Published: October 2018

Même si le nombre de séparations et de divorces est plutôt stable depuis quelques années, la structure des familles post-séparation continue à se diversifier. La séparation est une période critique pour les membres de la famille qui peut comporter des défis, notamment sur le plan de la résolution des conflits et du maintien des relations. À cet effet, il existe plusieurs services destinés aux parents qui se séparent, dont la médiation familiale. Parce que les besoins de l’enfant sont au cœur du processus de médiation familiale, des acteurs s’interrogent sur la place réelle qu’on doit lui accorder dans ce processus. L’inclusion de l’enfant dans la médiation familiale est appelée à se développer dans les prochaines années si l’on conjugue évolution du statut de l’enfant dans la société et dans les législations et réalité du vécu des parents séparés en conflits. Mais les médiateurs familiaux sont-ils prêts à investir cette nouvelle forme de pratique ? Quels sont les avantages et enjeux de cette pratique ?
