HUBUNGAN PELAYANAN APARATUR PEMERINTAHAN DESA DENGAN TINGKAT KEPUASAN MASYARAKAT DESA DI KECAMATAN BALUNG KABUPATEN JEMBER
Authors: Supriyadi Ibnu
Published: March 2020

Penyelenggaraan pelayanan publik seringkali menghadapi hambatan dalam memformulasikan strategi pelayanan. Pertama, karena mental atau anggapan sebagai pelayan umum yang dituntut untuk memberikan kualitas pelayanan yang sama untuk seluruh anggota masyarakat yang ada dalam masyarakat, walaupun sebenarnya mereka mempunyai harapan yang berbeda. Kedua, karena penyelenggaraan pelayanan publik pada umumnya bersifat monopoli, maka keinginan untuk menjadi lembaga pelayanan yang berfokus kepada pencapaian kepuasan masyarakat relatif lemah.Sehingga masih banyak pelaksanaan pelayanan publik yang menurut kacamata masyarakat masih banyak permasalahan sehingga terasa  kurang kurang memuaskan. Salah satunya dalam pelayanan adalah pembuatan Kartu Keluarga (KK).Sehingga penelitian perlu di lakukan dengan tujuan untuk mendiskripsikan hubungan antara pelayanan aparatur pemerintahan desa secara sistematis, faktual dan akurat mengenai fakta-fakta terhadap tingkat kepuasan masyarakat desa di  Kecamatan balung Kabupaten Jember. Populasinya adalah seluruh penduduk yang ada di  desa-desa di Kecamatan Balung Kabupaten Jember,  sedangkan sampel yang diambil adalah sebanyak 30 (tiga puluh) Kepala Keluarga. Pengumpulan data dalam penelitian ini menggunakan kuesioner, yang disusun dengan modifikasi dalam skala likert dengan 5 (lima) kategori, untuk jawaban a diberi kreteria sangat baik dengan nilai 5 (lima), untuk jawaban e diberi kreteria sangat buruk dengan nilai 1 (satu). Data yang sudah terkumpul selanjutnya di analisis dengan menggunakan teknik analisis deskriptif dan analisis Korelasi Rank Spearmans. Hasil penelitian menunjukkan terdapat hubungan yang positif dan signifikan antara pelayanan aparatur pemerintahan desa dengan tingkat kepuasan masyarakat desa di Kecamatan Jenggawah Kabupaten Jember. Hal ini tampak dari nilai korelasi hitung sebesar  0,755.Hasil perhitungan ini dikonsultasikan dengan korelasi rank spearmans tabel dengan jumlah N=30 maka didapatkan angka  korelasi tabel sebesar 0,364. Dengan demikian dapat disimpulkan bahwa r hitung lebih besar dari r tabel (r hit. > r tab. yaitu 0,755 > 0,364).

Tantangan bagi perusahaan yang menjual produknya secara kredit adalah menjaga kontinuitas kegiatan operasional atau produksinya. Perusahaan harus menanamkan sejumlah modalnya dalam piutang untuk jangka waktu tertentu. Sehingga untuk waktu tersebut perusahaan harus menyediakan tambahan dana untuk menjaga kontinuitas kegiatan operasional atau produksinya. Perusahaan harus mengupayakan efisiensi dalam penanaman modal dalam piutang. Strategi yang digunakan untuk mengupayakan efisiensi dalam piutang adalah dengan memberikan potongan tunai kepada pelanggan yang menyetorkan hutangnya pada periode potongan tunai. Tujuan dari penelitian ini adalah mengetahui dampak pemberian potongan tunai terhadap efisiensi modal kerja dan keuntungan perusahaa.Penelitian di lakukan terhadap berbagai catatan keuangan perusahaan Tahu Kriuk “QUEEN” selama tahun 2011 dalam bentuk laporan keuangan triwulan. Analisis dilakukan dengan cara membandingkan tingkat perputaran piutang, hari rata-rata pengumpulan piutang, dan investasi rata-rata dalam piutang atas periode sebelum dan sesudah pemberian potongan tunai, serta melihat dampaknya terhadap biaya investasi marginal dan keuntungan perusahaan. Hasil analisis menunjukkan bahwa dengan pemberian potongan tunai, perusahaan mampu mengumpulkan piutangnya rata – rata 5 hari lebih cepat, adanya penurunan kebutuhan modal kerja sebesar Rp. 939.846,55, adanya penurunan investasi rata-rata dalam piutang sebesar Rp. 1.566.355,48,  adanya peluang tambahan keuntungan sebesar Rp. 160.543,- dan keuntungan perusahaan mengalami kenaikan sebesar Rp. 43.343,- sehingga kebijakan pemberian potongan tunai dalam upaya efesiensi modal kerja dapat dilanjutkan.

Keterbatasan keuangan yang dimiliki desa menyebabkan ketimpangan pembangunan antara desa dengan kota. Diperlukan keberpihakan pemerintah pusat dan daerah dalam mendukung ketersediaaan anggaran bagi desa untuk melaksanakan tata kelola pemerintahan dan pembangunan. Alokasi Dana Desa (ADD) merupakan salah satu cara untuk mempercepat pembangunan di desa. Sejak tahun 2015, terjadi peningkatan yang signifikan atas penerimaan ADD karena Kabupaten wajib menganggarkan minimal 10% dari APBD untuk alokasi dana desanya sesuai amanah Undang-undang Nomor 6 Tahun 2014. Peningkatan ADD tersebut merupakan berkah dan tantangan bagi desa untuk bisa mengelola sesuai dengan prinsip-prinsip tata kelola pemerintahan yang baik (good governance). Karena desa saat ini masih dihadapkan pada keterbatasan kualitas sumber daya aparatur yang rendah, rendahnya kemampuan perencanaan, dan sarana prasarana lam pengelolaan ADD. Kata Kunci: Pengelolaan, Alokasi Dana Desa

Published: March 2020

Restorations in the previous sector are of great importance because they are part of the individual's communication. Its elaboration is very complex because the dental tissue has a variety of colors, effects, shapes and texture. Studying color is not easy, as it is influenced by several factors, which can produce frustrating results, both for the professional and for the patient when satisfactory results are not achieved. We must understand that color is the shock of a beam of light towards an object, which is fragmented into three dimensions: chroma, value and saturation. Another important aspect for the development of restorations is to create prostheses that go according to the facial shape, and personality of the patient. The objective is to understand the behavior of color, the factors that influence it, shape and texture that belongs to the individual, with the purpose of developing natural-looking dental prostheses that can be mimicked with their surroundings and emotional aspect of the patient.
Potential Themis-family Asteroid Contribution to the Jupiter-family Comet Population
Authors: Hsieh Henry H. , Novaković Bojan , Walsh Kevin J. , Schörghofer Norbert
Published: March 2020

Recent dynamical analyses suggest that some Jupiter family comets (JFCs) may originate in the main asteroid belt instead of the outer solar system. This possibility is particularly interesting given evidence that icy main-belt objects are known to be present in the Themis asteroid family. We report results from dynamical analyses specifically investigating the possibility that icy Themis family members could contribute to the observed population of JFCs. Numerical integrations show that such dynamical evolution is indeed possible via a combination of eccentricity excitation apparently driven by the nearby 2:1 mean-motion resonance with Jupiter, gravitational interactions with planets other than Jupiter, and the Yarkovsky effect. We estimate that, at any given time, there may be tens of objects from the Themis family on JFC-like orbits with the potential to mimic active JFCs from the outer solar system, although not all, or even any, may necessarily be observably active. We find that dynamically evolved Themis family objects on JFC-like orbits have semimajor axes between 3.15 and 3.40 au for the vast majority of their time on such orbits, consistent with the strong role that the 2:1 mean-motion resonance with Jupiter likely plays in their dynamical evolution. We conclude that a contribution from the Themis family to the active JFC population is plausible, although further work is needed to better characterize this contribution.
Spectroscopic Determination of Stellar Parameters and Oxygen Abundances for Hyades/Field G–K Dwarfs
Authors: Takeda Yoichi , Honda Satoshi
Published: March 2020

It has been suggested that Fe abundances of K dwarfs derived from Fe i and Fe ii lines show considerable discrepancies, and oxygen abundances determined from high-excitation O i 7771–5 triplet lines are appreciably overestimated (the problem becoming more serious toward lower T
eff), which, however, has not yet been widely confirmed. With the aim of clarifying this issue, we spectroscopically determined the atmospheric parameters of 148 G–K dwarfs (Hyades cluster stars and field stars) by assuming the classical Fe i/Fe ii ionization equilibrium as usual, and determined their oxygen abundances by applying the non-local thermal equilibrium spectrum fitting analysis to O i 7771–5 lines. It turned out that the resulting parameters did not show any significant inconsistency with those determined by other methods (for example, the mean differences in T
eff and

from the well-determined solutions of Hyades dwarfs are mostly ≲100 K and ≲0.1 dex). Likewise, the oxygen abundances of Hyades stars are around [O/H] ∼ +0.2 dex (consistent with the metallicity of this cluster) without exhibiting any systematic T
eff-dependence. Accordingly, we conclude that parameters can be spectroscopically evaluated to a sufficient precision in the conventional manner (based on the Saha–Boltzmann equation for Fe i/Fe ii) and oxygen abundances can be reliably determined from the O i 7771–5 triplet for K dwarfs as far as stars of T
eff ≳ 4500 K are concerned. We suspect that previously reported strongly T
eff-dependent discrepancies may have stemmed mainly from overestimation of weak-line strengths and/or improper T
eff scale.

The Green Bank North Celestial Cap (GBNCC) pulsar survey will cover the entire northern sky (δ > −40°) at 350 MHz, and is one of the most uniform and sensitive all-sky pulsar surveys to date. We have created a pipeline to reanalyze GBNCC survey data to take a 350 MHz census of all pulsars detected by the survey, regardless of their discovery survey. Of the 1413 pulsars in the survey region, we were able to recover 670. For these we present measured signal-to-noise ratios (S/N), flux densities, pulse widths, profiles, and where appropriate, refined measurements of dispersion measures (DMs) (656 out of 670) and new or improved spectral indices (339 out of 670 total, 47 new, 292 improved). We also measure the period-pulse width relation at 350 MHz to scale as

. Detection scans for several hundred sources were reanalyzed in order to inspect pulsars’ single pulse behavior and 223 were found to exhibit evidence of nulling. With a detailed analysis of measured and expected S/N values and the evolving radio frequency interference environment at 350 MHz, we assess the GBNCC survey’s sensitivity as a function of spin period, DM, and sky position. We find the sky-averaged limiting flux density of the survey to be 0.74 mJy. Combining this analysis with PsrPopPy pulsar population simulations, we predict 60/5 nonrecycled/MSP discoveries in the survey’s remaining 21,000 pointings, and we begin to place constraints on population model parameters.
ZFIRE: Measuring Electron Density with [O ii] as a Function of Environment at z = 1.62

The global star formation rates (SFR) of galaxies at fixed stellar masses increase with redshift and are known to vary with environment up to z ∼ 2. We explore here whether the changes in the SFRs also apply to the electron densities of the interstellar medium by measuring the [O ii] (

,

) ratio for cluster and field galaxies at z ∼ 2. We measure a median electron density of

 = 366 ± 84 cm

for six galaxies (with 1σ scatter = 163 cm

) in the Ultra-Deep Survey (UDS) protocluster at z = 1.62. We find that the median electron density of galaxies in the UDS protocluster environment is three times higher compared to the median electron density of field galaxies (

 = 113 ± 63 cm

and 1σ scatter = 79 cm

) at comparable redshifts, stellar mass, and SFR. However, we note that a sample of six protocluster galaxies is insufficient to reliably measure the electron density in the average protocluster environment at z ∼ 2. We conclude that the electron density increases with redshift in both cluster and field environments up to z ∼ 2 (

 = 30 ± 1 cm

for z ∼ 0 to

 = 254 ± 76 cm

for z ∼ 1.5). We find tentative evidence (∼2.6σ) for a possible dependence of electron density on environment, but the results require confirmation with larger sample sizes.
Proper Motions of the Radio Source Orion MR, Formerly Known as Orion n, and New Sources with Large Proper Motions in Orion BN/KL
Authors: Rodríguez Luis F. , Dzib Sergio A. , Zapata Luis , Lizano Susana , Loinard Laurent , Menten Karl M. , Gómez Laura
Published: March 2020

The infrared source known as Orion n was detected in 1980. About two decades later, sensitive observations made with the Very Large Array (VLA) revealed the presence of a spatially coincident millijansky double source that appeared to be its radio counterpart. However, over the years it has been concluded that the radio source shows large proper motions to the south while the infrared source n is stationary. Here we reanalyze the proper motions of the radio source adding both older and newer VLA observations than previously used. We confirm the proper motions of the double radio source that at present no longer coincides positionally with the infrared source. We propose that the infrared source is stationary while the radio source is moving as a result of the explosion that took place in this region some 500 yr ago. Considering the paper where it was first reported, we refer to this double radio source as Orion MR. Additionally, we use these new observations to fully confirm the large proper motions of the sources IRc23 and Zapata 11. Together with sources BN, I, Orion MR, and x, there are at least six compact sources that recede from a common point in Orion BN/KL. However, IRc23 is peculiar in that its ejection age appears to be only 300 yr. The relatively large number of sources rules out as a possible mechanism the classic three-body scenario since then only two escaping bodies are expected: a tight binary plus the third star involved in the encounter.

We present the discovery and optical follow-up of the faintest supernova-like transient known. The event (SN 2019gsc) was discovered in a star-forming host at 53 Mpc by ATLAS. A detailed multicolor light curve was gathered with Pan-STARRS1 and follow-up spectroscopy was obtained with the Nordic Optical Telescope and Gemini-North. The spectra near maximum light show narrow features at low velocities of 3000–4000 km s−1, similar to the extremely low-luminosity SNe 2010ae and 2008ha, and the light curve displays a similar fast decline (Δm
15(r) = 0.91 ± 0.10 mag). SNe 2010ae and 2008ha have been classified as SNe Iax, and together the three either make up a distinct physical class of their own or are at the extreme low-luminosity end of this diverse supernova population. The bolometric light curve is consistent with a low kinetic energy of explosion (E
k ∼ 1049 erg s−1), a modest ejected mass (M
ej ∼ 0.2  M
⊙), and radioactive powering by 56Ni (M
Ni ∼ 2 × 10−3  M
⊙). The spectra are quite well reproduced with radiative transfer models (TARDIS) and a composition dominated by carbon, oxygen, magnesium, silicon, and sulfur. Remarkably, all three of these extreme Iax events are in similar low-metallicity star-forming environments. The combination of the observational constraints for all three may be best explained by deflagrations of near M
Ch hybrid carbon–oxygen–neon white dwarfs that have short evolutionary pathways to formation.

The complex circumstellar environment around the massive binary and luminous blue variable η Carinae is known to harbor numerous light molecules, emitting most strongly in rotational states with upper level energies to ∼300 K. In circumstellar gas, the complex organic molecule methanol (CH3OH) has been found almost exclusively around young stellar objects, and thus regarded as a signpost of recent star formation. Here we report the first potential detection of methanol around a highly evolved high-mass star, while using the Atacama Large Millimeter Array to investigate molecular cloud conditions traced by CO (2–1) in an orbit phase preceding the 2020 periastron. The methanol emission originates from hot (T
gas ≃ 700 K) material, ∼2″ (0.02 pc) across, centered on the dust-obscured binary, and is accompanied by prominent absorption of continuum radiation in a cooler (T
gas ≃ 110 K) layer of gas. We also report a first detection of water in Herschel observations at 557 and 988 GHz. The methanol abundance is several to 50 times higher than observed toward several lower-mass stars, while water abundances are similar to those observed in cool, dense molecular clouds. The very high methanol:water abundance ratio in the core of η Car may suggest methanol formation processes similar to Fischer–Tropsch-type catalytic reactions on dust grains. These observations prove that complex molecule formation can occur in a chemically evolved massive stellar environment, given sufficient gas densities and shielding conditions as may occur in material around massive interacting companions and merger remnants.
SDSS-IV MaNGA: Kinematic Asymmetry as an Indicator of Galaxy Interaction in Paired Galaxies

The interaction between galaxies is believed to be the main origin of the peculiarities of galaxies, which disturbs not only the morphology but also their kinematics. These disturbed and asymmetric features are the indicators of galaxy interaction. We study the velocity field of the ionized gas of the paired galaxies in the SDSS-IV MaNGA IFU survey. Using the kinemetry package, we fit the velocity field of the ionized gas to quantify the degree of kinematic asymmetry. We find that the star formation rate (SFR) of the paired galaxies with high kinematic asymmetry is significantly enhanced even when the projected separation between the pair members is quite large (

). On the contrary, no significant SFR enhancement is found for the paired galaxies with low kinematic asymmetry even when their projected separation is small (

). Moreover, we also find that the fraction of galaxies with high kinematic asymmetry is much higher in close pairs (

) than those with larger

, which explains well the early statistical finding of the significant SFR enhancement in close pairs. Our new findings illustrate that the kinematic asymmetry is an excellent indicator of galaxy–galaxy interaction strength, which helps us better understand the merging stage of the observed galaxy pairs.
Takotsubo Cardiomyopathy after Elective Aortic and Mitral Valve Replacement
Authors: Vazhev Zaprin , Stoev Hristo
Published: March 2020

Takotsubo cardiomyopathy is a syndrome characterized by transient acute left ventricular dysfunction, electrocardiographic changes that can mimic acute myocardial infarction and minimal release of myocardial enzymes in the absence of obstructive coronary artery disease (CAD). Reports of Takotsubo syndrome after cardiac surgery are exceptional. We describe a case of Takotsubo cardiomyopathy in a 57-year-old man after elective aortic and mitral valve replacement following recent convalescence from infective endocarditis. Takotsubo syndrome should be considered in the differential diagnosis of patients presenting acute myocardial infarction, cardiogenic shock or any low cardiac output syndrome after cardiac surgery.
Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating from the Para-Hisian area - QRS Morphology Change and Late Effect of the Ablation: Case Series
Authors: Dzhinsov Krasimir R. , Stoyanov Milko K. , Shalganov Tchavdar N.
Published: March 2020

Introduction: Radiofrequency catheter ablation of idiopathic ventricular arrhythmias originating in the para-Hisian region could be challenging because of a potential risk of iatrogenic atrioventricular block. Uncommonly, shift of the exit site during the ablation can be observed. Consequently, different approaches of radiofrequency catheter ablation of para-Hisian ventricular foci can be needed.

 

Case series presentation: Three patients (2 males) underwent electroanatomical mapping and catheter ablation for idiopathic premature ventricular contractions originating near the His bundle. Patients underwent 24-h ECG Holter monitoring during follow-up. All patients had premature ventricular contractions with left bundle branch block morphology and inferior or horizontal axis. However, change of QRS morphology during ablation was observed, due to a change in the exit site. In two patients there was reduction of the arrhythmia burden after initially unsuccessful procedure. Mapping and ablation in the aortic root were needed in one patient. There were no complications.

 

Discussion: Radiofrequency catheter ablation of para-Hisian ventricular arrhythmias is feasible and safe when performed cautiously. A change in the premature ventricular contractions’ morphology and exit site during ablation may ensue; therefore, extensive mapping on both sides of the interventricular septum as well as in the aortic root may be warranted.

Authors: Nasr-Esfahani Maryam , Doosti Abbas , Sazegar Hossein
Published: March 2020

Background: The purpose of the present study was to produce a pcDNA3.1(+)-ureA recombinant vector and evaluate the capacity of this vector to stimulate the immune response against H. pylori infection in infused BALB/c mice. 

 

Materials and methods: The pcDNA3.1(+)-ureA construct was prepared and transformed into E. coli, successfully. The animals we used in the study were allotted into three groups for infusion of 1) recombinant plasmid, 2) pcDNA3.1(+)-ureA + nanoparticles, and 3) pcDNA3.1(+). Blood and tissue specimens from each group of mice were collected at days 15, 30, and 45 after the last infusion and the expression levels of cytokines such as TGF-β1, IL-4, and IFNγ genes comparing to GAPDH as well as the expression of ureA in the mice’s thigh muscle were evaluated. 

 

Results: The genes expression analysis showed that the IL4 expression significantly decreased (p<0.001) but IFNγ and TGF-β1 expression increased in the blood of infused mice (p<0.001). Also, the urea expression level in pcDNA3.1(+)-urea and pcDNA3.1(+)-ureA+ nanoparticle 15, 30, and 45 days after the last infusion was significantly different (p<0.001) and its expressions at days 15 and 30 were significantly different (p<0.001), but 45 days after the last infusion it was not significantly different (p>0.05). 

 

Conclusion: The pcDNA3.1(+)-ureA recombinant vector with or without chitosan nanoparticles can stimulate the immune response in animal models against H. pylori infection. Also, after combining the recombinant vector with nanoparticles we observed a better immune response was observed. In future studies this recombinant construct can be used as a biomarker and therapeutic approaches in eukaryotic systems.
Folklore y cultura de masas
Authors: Schenda Rudolf
Published: March 2020

Partiendo del concepto de folklore acuñado en 1929 por Bogatyrev y Jakobson y aún válido, se propone una revisión y actualización del mismo a la vista de las nuevas circunstancias de su uso. La reproducción técnica de los hechos folklóricos y su disponibilidad en el espacio y el tiempo hicieron posible durante los siglos XVIII y XIX su difusión y consumo masivos y una profunda modificación de sus funciones anteriores. Ya en nuestro siglo, los medios de comunicación -importantes creadores y conservadores de folklore- lo utilizan, condensado en slogans y asociado a otros mensajes, para fines muy diversos y no siempre inocentes.

La indumentaria como símbolo regional. La tradición inventada en el caso del traje femenino de Montehermoso
Authors: Valadés Sierra Juan Manuel
Published: March 2020

La indumentaria, como otros aspectos de la cultura, se halla sujeta a la variabilidad en tiempo y espacio, de manera que el estudio de los modos de vestir tradicionales debe abordarse desde una perspectiva diacrónica y teniendo en cuenta las modificaciones que aparecen cuando los trajes desbordan sus límites comunitarios. Por otro lado, determinados modelos indumentales pueden llegar a convertirse en símbolo de una comunidad específica, forjándose entonces una imagen estereotipada de ellos que coincide con lo que se considera como la versión auténtica del traje. En el caso de Extremadura, y a falta de otros indicadores culturales válidos, el traje de la mujer de Montehermoso (Cáceres) llega, pues, a convertirse en símbolo regional, partiendo de la manipulación y distorsión de sus elementos formales tradicionales para la consecución de una imagen específica y diferencial, proceso que podemos considerar como la invención de una tradición.

Les fils d’affranchis dans l’Ordo Pompeianus
Authors: Łoś Andrzej
Published: March 2020

L’analyse de la documentation pompéienne conduit l’A. à rejoindre la position de P. Castrén sur la composition sociale de la classe dirigeante de Pompéi à la fin des Julio-Claudiens et sous les Flaviens (mais pour des motifs non identiques) ; la seconde moitié du Ier siècle av. J.-C. a vu la croissance du rôle politique des descendants d’affranchis. Ce phénomène devrait s’expliquer par une érosion progressive de la place occupée par la plebs ingenua dans la société romaine du Ier siècle de notre ère ; c’est l’évolution économique et sociale de l’Italie qui justifie ce paradoxe : les anciens esclaves et leurs enfants avaient plus de chance de parvenir au succès (sur le plan économique puis social et enfin politique) que les plébéiens de naissance libre ; ainsi, tous les agriculteurs que Pline citait en modèle à son époque étaient des affranchis qui. par leur dynamisme et leur capacité à s’adapter aux nouvelles conditions d’exploitation de la terre, pouvaient ainsi voir ouvrir la porte des curies pour leurs descendants.

Published: March 2020

Boron oxide-based systems on structure and properties are similar to silicate systems, but they are more fusible and so are widely used in modelling various metallurgical processes. This paper presents the results of viscosity, electrical conductivity, surface tension and density measurements of the B2O3–CaO system with a content of 25–45% CaO in the temperature range above the liquidus temperature. To measure viscosity, vibration viscometry was used. Electrical conductivity was measured via the contact method using an alternating current bridge. Surface tension and density were measured using the lying drop method. The obtained results were used to describe the structure of borate melts.

This paper aims to study convective drying of industrial hollow bricks in a tunnel dryer. A transient mathematical model based on the heat and mass conservation equations applied to the air and brick was derived and the numerical solution (finite-volume method) of the governing equations is presented. Predicted and experimental data of the average moisture content and the temperature of the product during the drying process are compared and a good concordance was verified. Numerical results inside the bed confirm an almost null difference between the moisture content along the process. Similar behavior was verified to the product temperature. These results confirm an efficient drying process.
