PELAKSANAAN PASAL 4 AYAT (1) PERATURAN PEMERINTAH REPUBLIK INDONESIA NOMOR 11 TAHUN 2010 TENTANG PENERTIBAN DAN PENDAYAGUNAAN TANAH TERLANTAR DI KABUPATEN BLITAR
Authors: Iftitah Anik 
Published: April 2018

Peraturan Pemerintah Republik Indonesia Nomor 11 Tahun 2010 tentang Penertiban dan Pendayagunaan Tanah Terlantar (PP 11/2010) dibentuk guna menyelesaikan persoalan penelantaran tanah di Indonesia. Namun, justru Perkebunan Kismo Handayani di Kabupaten Blitar sebagai tanah yang masuk database tanah terindikasi terlantar, justru mengalami puncak konflik pasca pelaksanaan PP 11/2010. Hal tersebut melatarbelakangi peneliti untuk meneliti pelaksanaan dan akibat pelaksanaan Pasal 4 Ayat (1) PP 11/2010 di Kabupaten Blitar. Penelitian hukum empiris di Perkebunan Kismo Handayani di Desa Soso Kecamantan Gandusari Kabupaten Blitar menggunakan teori sistem hukum, menunjukkan bahwa pelaksanaan Pasal 4 Ayat (1) PP 11/2010 di Kabupaten Blitar, menjadikan tanah sengketa sebagai indikator tanah terindikasi terlantar (suatu pengindikasian tanah terindikasi terlantar yang tidak sesuai dengan substansi PP 11/2010), berakibat terhentinya pelaksanaan PP 11/2010 pada tahap identifikasi dan penelitian, tidak ada satupun hak atas tanah di Kabupaten Blitar yang ditetapkan oleh Kepala BPN-RI sebagai tanah terlantar, ketidakjelasan status hukum hak atas tanah Perkebunan Kismo Handayani selama ± 6 tahun ( 2011-2016 ), dan memuncaknya ekskalasi konflik di area eks-HGU Perkebunan Kismo Handayani pada rentang waktu Tahun 2011-2016 yang pada akhirnya diatasi dengan redistribusi dan penerbitan sertifikat HGU atas nama Kismo Handayani pada tahun 2017. Hasil penelitian ini patut dijadikan bahan refleksi. Tertib maupun konflik, merupakan akibat pelaksanaan (substansi) hukum yang sangat bergantung pada pelaksana hukum yang akan berimplikasi pada wujud budaya hukum masyarakat.

Published: April 2018

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor ﬁom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in ﬁve levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest ﬂesh weight

Published: April 2018

This study was aimed at assessing the efficacy of several multiple liquid biofertilizers found in the market on the growth and production of sweet corn. A factorial completely randomized design was used. The first factor was the type of multiple liquid biofertilizers (PHMC) consisting of three levels, namely PHMC 1, PHMC 2, and PHMC 3. The second factor was synthetic fertilizer rates consisting of five levels, namely 0, 25, 50, 75, and 100% of recommended rate (R). Results showed that the application of PHMC 3 combined with synthetic fertilizer treatments (05 R and 25% R) significantly increased stem diameter (8 WAP). Plants treated with PHMC 3 application were found to have significantly higher number of leaves than those treated with PHMC 2 application at 6 WAP. Plant height, number of leaves, and weight, length, and circumference of main cob of plants treated with 50%R synthetic fertilizer were higher than those of plants treated with 0%R and 25%R synthetic fertilizer. Meanwhile, plants treated with 75%R synthetic fertilizer were found to have better values for girth, leave width, flowering time, harvesting time, number of cobs, dry weight of shoots and roots, grain total soluble solids (TSS) content, and cobs weight than those of plants treated with 0, 25, and 50%R synthetic fertilizer.

Published: April 2018

The needs for animal protein increase significantly as the number and prosperity level of people increase. Ducks are water poultry that can be used to supply meat and eggs to fulfill people need for protein. Ducks are the second most important egg producers after chickens. In Indonesia, duck eggs share about 30-40% of total egg supply (Suharno 2002). This study was aimed at assessing the production performance of male local ducks fed torch ginger flower (Etlingera elatior) solution included in commercial ration. Male local ducks aged 2 weeks with average initial body weight of 450 g were used. Commercial feed was mixed with torch ginger flower solution. A completely randomized design with 4 treatments and 3 replicates was used. Treatments consisted of four levels of torch ginger flower solution, namely 0, 2.5, 5.0, and 7.5%. Data were subjected to an analysis of variance and measurements were taken on feed intake, body weight gain, feed conversion, and mortality rate. Results showed that no significant differences (P>0.05) were found in all parameters measured. The average feed intake was 4037.67±205.748 g, body weight gain was 1034.79±129.14 g/head, and feed conversion was 3.94±0.45. The mortality rate was found to be 0% indicating no bird was found died in all treatment groups. Provision of commercial feed with a mixture of a solution of interest ginger flower is not able to improve the performance of male local ducks.Key words: animal protein, water poultry, feed intake, body weight gain, feed conversion.
The Envelope Kinematics and a Possible Disk around the Class 0 Protostar within BHR7
Authors: Tobin John J. , Bos Steven P. , Dunham Michael M. , Bourke Tyler L. , van der Marel Nienke 
Published: April 2018

Abstract
We present a characterization of the protostar embedded within the BHR7 dark cloud, based on both photometric measurements from the near-infrared to millimeter and interferometric continuum and molecular line observations at millimeter wavelengths. We find that this protostar is a Class 0 system, the youngest class of protostars, measuring its bolometric temperature to be 50.5 K, with a bolometric luminosity of 9.3 L
☉. The near-infrared and Spitzer imaging show a prominent dark lane from dust extinction separating clear bipolar outflow cavities. Observations of 13CO (

), C18O (

), and other molecular lines with the Submillimeter Array (SMA) exhibit a clear rotation signature on scales <1300 au. The rotation can be traced to an inner radius of ∼170 au and the rotation curve is consistent with an R
−1 profile, implying that angular momentum is being conserved. Observations of the 1.3 mm dust continuum with the SMA reveal a resolved continuum source, extended in the direction of the dark lane, orthogonal to the outflow. The deconvolved size of the continuum indicates a radius of ∼100 au for the continuum source at the assumed distance of 400 pc. The visibility amplitude profile of the continuum emission cannot be reproduced by an envelope alone and needs a compact component. Thus, we posit that the resolved continuum source could be tracing a Keplerian disk in this very young system. If we assume that the continuum radius traces a Keplerian disk (R ∼ 120 au) the observed rotation profile is consistent with a protostar mass of 1.0 M
☉.
GRMHD Simulations of Visibility Amplitude Variability for Event Horizon Telescope Images of Sgr A*
Authors: Medeiros Lia , Chan Chi-kwan , Özel Feryal , Psaltis Dimitrios , Kim Junhan , Marrone Daniel P. , Sa̧dowski Aleksander 
Published: April 2018

Abstract
The Event Horizon Telescope will generate horizon scale images of the black hole in the center of the Milky Way, Sgr A*. Image reconstruction using interferometric visibilities rests on the assumption of a stationary image. We explore the limitations of this assumption using high-cadence disk- and jet-dominated GRMHD simulations of Sgr A*. We also employ analytic models that capture the basic characteristics of the images to understand the origin of the variability in the simulated visibility amplitudes. We find that, in all simulations, the visibility amplitudes for baselines oriented parallel and perpendicular to the spin axis of the black hole follow general trends that do not depend strongly on accretion-flow properties. This suggests that fitting Event Horizon Telescope observations with simple geometric models may lead to a reasonably accurate determination of the orientation of the black hole on the plane of the sky. However, in the disk-dominated models, the locations and depths of the minima in the visibility amplitudes are highly variable and are not related simply to the size of the black hole shadow. This suggests that using time-independent models to infer additional black hole parameters, such as the shadow size or the spin magnitude, will be severely affected by the variability of the accretion flow.
Bow Shock in Merging Cluster A520: The Edge of the Radio Halo and the Electron–Proton Equilibration Timescale
Authors: Wang Qian H. S. , Giacintucci Simona , Markevitch Maxim 
Published: April 2018

Abstract
We studied the prominent bow shock in the merging galaxy cluster A520 using a deep Chandra X-ray observation and archival VLA radio data. This shock is a useful diagnostic tool, owing to its clear geometry and relatively high Mach number. At the “nose” of the shock, we measure a Mach number of

. The shock becomes oblique away from the merger axis, with the Mach number falling to ≃1.6 around 30° from the nose. The electron temperature immediately behind the shock nose is consistent with that from the Rankine–Hugoniot adiabat, and is higher (at a 95% confidence) than expected for adiabatic compression of electrons followed by Coulomb electron–proton equilibration, indicating the presence of equilibration mechanisms faster than Coulomb collisions. This is similar to an earlier finding for the Bullet cluster. We also combined four archival VLA data sets to obtain a better image of the cluster’s giant radio halo at 1.4 GHz. An abrupt edge of the radio halo traces the shock front, and no emission is detected in the pre-shock region. If the radio edge were due only to adiabatic compression of relativistic electrons in pre-shock plasma, we would expect a pre-shock radio emission detectable in this radio data set; however, an interferometric artifact dominates the uncertainty, so we cannot rule this model out. Other interesting features of the radio halo include a peak at the remnant of the cool core, suggesting that the core used to have a radio minihalo, and a peak marking a possible region of high turbulence.
Unlocking the Full Potential of Extragalactic Lyα through Its Polarization Properties
Authors: Eide Marius B. , Gronke Max , Dijkstra Mark , Hayes Matthew 
Published: April 2018

Abstract
Lyα is a powerful astrophysical probe. Not only is it ubiquitous at high redshifts, it is also a resonant line, making Lyα photons scatter. This scattering process depends on the physical conditions of the gas through which Lyα propagates, and these conditions are imprinted on observables such as the Lyα spectrum and its surface brightness profile. In this work, we focus on a less-used observable capable of probing any scattering process: polarization. We implement the density matrix formalism of polarization into the Monte Carlo radiative transfer code tlac. This allows us to treat it as a quantum mechanical process where single photons develop and lose polarization from scatterings in arbitrary gas geometries. We explore static and expanding ellipsoids, biconical outflows, and clumpy multiphase media. We find that photons become increasingly polarized as they scatter and diffuse into the wings of the line profiles, making scattered Lyα polarized in general. The degree and orientation of Lyα polarization depends on the kinematics and distribution of the scattering H i gas. We find that it generally probes spatial or velocity space asymmetries and aligns itself tangentially to the emission source. We show that the mentioned observables, when studied separately, can leave similar signatures for different source models. We conclude by revealing how a joint analysis of the Lyα spectra, surface brightness profiles, and polarization can break these degeneracies and help us extract unique physical information on galaxies and their environments from their strongest, most prominent emission line.
Race, Ethnicity and the US Immigrants’ Rights Movement: Observations from Southern Arizona
Authors: Cohen James 
Published: April 2018

À partir d’un travail de terrain sur le mouvement des droits des immigrés dans le sud de l’Arizona, cet article examine les dynamiques ethnoraciales et les mobilisations collectives à l’époque d’Obama. En quoi les formes de discrimination que subissent les immigrés sont-elles ethnoraciales ? En quoi les mouvements de défense des droits des immigrés sont-ils aussi des vecteurs d’antiracisme ? Quel rapport entre race, ethnicité et polarisation politique croissante aux États-Unis ? En posant ces questions l’article vise aussi à encourager la réflexion critique sur le statut des catégories ethnoraciales, leur usage et leurs abus possibles dans le travail d’interprétation de dynamiques socio-politiques concrètes.

Published: April 2018

Abstract
Electronic devices that are deformable in arbitrary directions would open up a new generation of applications such as epidermal electronics, implantable electronics and soft robotics. It would not be feasible to fabricate them with conventional rigid materials. To make the electronics stretchable, one can miniaturize the functional units and link them by stretchable interconnects. In this paper, we report a method for fabrication and characterization of stretchable interconnects using deformable materials based on carbon ink and thermoplastic polyurethane. The static resistances of interconnects were on average 296 Ω/□, and half of the samples withstood single strain up to 108 % elongation. Fabricated samples survived a 1000 cycles strain test up to 40 % of stretching.
Liquid Cooling in an LTCC-Module for a Switched Mode Amplifier

Published: April 2018

Abstract
Low Temperature Co-fired Ceramic (LTCC) is a proven packaging technology for microwave and millimetre-wave applications. Advanced low-loss material systems and improved manufacturing technology facilitate economic and highly reliable packaging solutions for automotive, telecom, medical and security applications. The fact that the substrate is hermetic facilitates unique packaging concepts where the LTCC multilayer is part of a hermetic package. However, there is a trade-off for the increasing complexity of these modules: When active devices are involved, the density of power dissipation is also rising. Liquid cooling provides an alternative where (forced air) convection cooling is not possible for lack of space or because of other limitations. With the integration of micro-channels into the LTCC-multilayer-stack the microwave-substrate becomes part of the piping for liquid cooling and brings the coolant in close contact to the heat source. As an example for such a solution a switched mode amplifier shall be presented that uses liquid cooling for the power transistor. Two different approaches for the routing of the cooling channels inside the LTCC are compared with cooling on a metal block at constant temperature. For the exact determination of all parameters, dissipated power and temperature on the die (junction temperature) a thermal test die is used instead of the transistor for the test vehicles.
