IMPLIKASI PENERAPAN PERATURAN PEMERINTAH NOMOR 18 TAHUN 2016 TENTANG ORGANISASI PERANGKAT DAERAH DI PEMERINTAH KOTA YOGYAKARTA
Authors: Anitasari Patricia Heny Dian
Published: March 2022

Peraturan Pemerintah No. 18 tahun 2016 telah mengamanatkan Pemerintah Daerah untuk meninjau kembali struktur kelembagaan dan organisasi pemerintahannya. Kondisi yang ada menunjukkan struktur organisasi yang berlebih namun di sisi lain anggaran Pemerintah Daerah terbatas. Penerbitan Peraturan Pemerintah ini diharapkan dapat mewujudkan pemerintahan daerah yang efektifitas dan efisiensi. Setelah diimplementasikan, perlu ada evaluasi kebijakan untuk mengetahui bagaimana dampak atau hasil kebijakan tersebut. Artikel ini diarahkan untuk mengkaji norma hukum positif dan membandingkan realitas restrukturisasi organisasi dan menunjukkan gap antara kondisi yang diharapkan dan kondisi yang ada. Dampak umum terlihat dari terjadinya pembentukan organisasi Pemerintahan Daerah yang homogen yang tercermin dalam kesamaan nomenklatur, bentuk dan jenis. Namun, ada masalah di balik homogenitas tersebut. Implikasinya yang jelas dalam kasus Pemerintah Kota Yogyakarta adalah adanya beberapa urusan pemerintahan tidak diakomodasi dengan baik dan ada peningkatan jumlah unit organisasi Pemerintah Daerah. Dalam urusan pemerintahan, beberapa urusan pemerintahan dengan intensitas sedikit akan digabungkan dengan urusan pemerintahan lainnya dalam struktur kelembagaan. Sedangkan dalam hal anggaran belanja pegawai meningkat karena berbanding lurus dengan kenaikan jumlah eselon II dan eselon III. Kondisi ini juga mempengaruhi penambahan fasilitas infrastruktur kerja yang harus disediakan.
MENGINTEGRASIKAN REFORMASI BIROKRASI DENGAN INOVASI SEKTOR PUBLIK
Authors: Prasetya Antonius Galih
Published: March 2022

Kebijakan reformasi birokrasi diterapkan pemerintah dalam rangka mewujudkan birokrasi berkelas dunia yang dinamis dan berdaya saing. Implementasinya telah memberikan beberapaperbaikan, meskipun belum cukup signifikan. Karena pendekatannya yang terlalu formalistis dan seragam, perubahan yang dihasilkan belum cukup memberikan dampak dan manfaat nyata bagi publik. Inovasi sektor publik dihadirkan untuk melengkapi kekurangan tersebut. Hal ini sesungguhnya juga telah dilakukan oleh instansi pemerintah, baik di level pusat maupun daerah. Meski demikian, inovasi sektor publik masih perlu diakselerasi agar pelaksanaannya berjalan lebih merata dan masif untuk mendorong reformasi. Tulisan ini menunjukkan pentingnya untuk melengkapi dan mengaitkan reformasi birokrasi dengan inovasi sektor publik. Hubungan di antara keduanya dapat dipandang baik sebagai hubungan integratif maupun komplementer. Menjadikan inovasi sebagai bagian dari area perubahan dan menyuntikkan dimensi inovasi dalam area perubahan yang selama ini telah ditetapkan adalah dua contoh cara untuk mengintegrasikan keduanya. Reformasi birokrasi dan inovasi sektor publik perlu dilakukan secara simultan untuk perbaikan penyelenggaraan pemerintahan yang komprehensif.

Authors: Tunsiah Siti
Published: March 2022

Diklat merupakan salah satu upaya pengembangan kompetensi yang dilakukan untuk mengisi kesenjangan kompetensi yang dimiliki Aparatur Sipil Negara (ASN) dalammelaksanakan tugas dan fungsi jabatannya. Untuk itu penyelenggaraan Diklat mulai dari perencanaan sampai dengan evaluasi harus dipastikan sesuai dengan pedoman penyelenggaraan baik secara substantif maupun administratif, dengan harapan tujuan penyelenggaraan Diklat untuk memenuhi kesenjangan kompetensi dapat tercapai. Peran Komite Penjamin Mutu (KPM) merupakan salah satu unsur yang dapat dimanfaatkan dalam mengawal penyelenggaraan Diklat sesuai dengan tugas dan fungsinya sebagai KPM. Berdasarkan hasil monitoring dan evaluasi yang dilakukan oleh Pusat Pengembangan Program dan Pembinaan LAN terhadap beberapa Lembaga Diklat, diperoleh data bahwa peran KPM belum dilakukan secara maksimal, KPM hanya sebatas diikutkan pada kegiatan rapat-rapat penyelenggaraan saja, belum kepada pelibatan pembuatan standar mutu baku penyelenggaraan Diklat yang dapat berupa petunjuk teknis penyelenggaraan ataupun Standar Operating Prosedur (SOP) kegiatan penyelenggaraan Diklat, pembuatan instrumen evaluasi penyelenggaraan atau bahkan evaluasi pasca pelatihan. Untuk itu, peran KPM harus dapat dimaksimalkan kembali, terutama pada saat melakukan monitoring dan evaluasi pasca Diklat sehingga Lembaga Diklat memiliki dan menyajikan data kualitas lulusan Diklat untuk membantu meningkatkan hasil diklat.
PERHUTANAN SOSIAL BAGI AKSES KEADILAN MASYARAKAT DAN PENGURANGAN KEMISKINAN
Authors: Murti Hani Afnita
Published: March 2022

Kemiskinan bukan hanya dimaknai sebagai persoalan deprivasi ekonomi semata, namun menyentuh krisis multidimensi. Masyarakat sekitar hutan merupakan salah satu kelompokmiskin terbesar di Indonesia. Sekitar 48,8 juta orang tinggal pada lahan hutan negara dan sekitar 10,2 juta diantaranya dikategorikan miskin dimana 71,06% menggantungkan hidupnya dari sumber daya hutan. Kondisi sosial ekonomi ini ditambah sulitnya masyarakat dalam mengakses hutan sering memercikkan dan menyalakan konflik kawasan hutan (konflik tenurial). Kebanyakan masyarakat sekitar hutan tidak memiliki perlindungan hukum baik terhadap legalitas maupun akses sumber daya hutan. Kebijakan Perhutanan Sosial muncul sebagai salah satu elemen dari reforma agraria, yang merupakan kebijakan yang digulirkan pemerintah untuk memastikan legalitas aset dan redistribusi tanah yang dikenal dengan kebijakan TORA (Tanah Objek Reforma Agraria), serta memastikan legalitas akses melalui kebijakan Perhutanan Sosial. Terdapat nexus yang menunjukkan korelasi positif yang diklaim oleh pemerintah bahwa kebijakan Perhutanan Sosial mampu menjadi alternatif kebijakan pengurangan angka kemiskinan. Perhutanan Sosial yang dilaksanakan secara klaster pada akhirnya akan menumbuhkan pusat ekonomi domestik sehingga kesempatan kerja terbuka luas dan penurunan kemiskinan akan signifikan. Keberadaan skema Perhutanan Sosial telah menjadi bagian integral dari pembangunan desa, pengentasan warga miskin, sekaligus membangun kemandirian sosial-ekonomi warga miskin di dalam dan sekitar hutan. Data rasio gini menunjukkan bahwa rasio gini tahun 2018 menunjukkan nilai lebih rendah yaitu 0,389 dari tahun 2017 sebesar 0,391. Sedangkan jumlah penduduk miskin juga berkurang menjadi 9,82% di tahun 2018 dibandingkan tahun 2017 sebesar 10,12%.

Published: March 2022

Dana desa meningkatkan kapasitas fiskal desa sehingga dapat digunakan untuk kesejahteraan masyarakat. Pengalokasian dan pemanfaatan yang tepat dapat mengurangi permasalahan desa,seperti kemiskinan. Akan tetapi, peningkatan dana desa belum sepenuhnya menunjukkan keberhasilan terhadap kondisi kemiskinan. Oleh sebab itu, penelitian ini bertujuan untuk mengkaji pengaruh dana desa terhadap kemiskinan di Aceh. Sebanyak 13 kabupaten/kota di Aceh diobservasi selama tiga tahun yaitu 2015 sampai 2017. Pengujian data dilakukan dengan menggunakan analisis regresi linear. Hasil penelitian menunjukkan bahwa peningkatan dana desa berpengaruh signifikan terhadap penurunan tingkat kemiskinan di Aceh. Peningkatan dana desa sebesar 1 persen dapat mengurangi tingkat kemiskinan di Aceh sebesar 0,316 persen. Hasil estimasi tersebut signifikan pada level 95 persen. Oleh sebab itu, dana desa merupakan instrumen kebijakan yang tepat dalam pengurangan kemiskinan di Aceh.

Authors: Grzelak Aleksander , Borychowski Michał , Staniszewski Jakub
Published: March 2022

Prior studies on the relationships between economic, environmental, and social dimensions of activity on agricultural holdings has yielded inconclusive results. This study examines the interactions between these spheres, with the aim of determining what the relationships between them might be. The study was based on the results of surveys of 120 farms in the Wielkopolska region of Poland, using structural equation modeling. The results showed significant and positive relationships between the economic, social, and environmental dimensions that could create synergies between them. The strongest positive relationships existed between the economic and environmental dimensions. Thus, economic and environmental development can be stimulated simultaneously. Analyzed farms from the Wielkopolska region positively discount the existing support system in the EU to the complementarity between environmental and economic governance. Our research indicates the need for the EU to implement a strategy adjusted to the individual region’s peculiarities in terms of environmental and social policies in rural areas.

The official parallax zero-point corrections largely reduce the global offset in the Gaia EDR3 parallaxes: the global parallax offsets are −27.9 μas and −26.5 μas (before correction) and +2.6 μas and +2.9 μas (after correction) for the five- and six-parameter solutions, respectively. The bias of the raw parallax measurements is significantly dependent on the G magnitudes, spectral colors, and positions of stars. The official parallax zero-point corrections could reduce parallax bias patterns with G magnitudes, while could not fully account the patterns in the spaces of the spectral colors and positions. In the current paper, a spatially dependent parallax zero-point correction model for Gaia EDR3 five-parameter solution in the LAMOST footprint is first provided with the advantage of huge number of stars in our sample.

We introduce a novel method for discerning optical telescope images of stars from those of galaxies using Gaussian processes (GPs). Although applications of GPs often struggle in high-dimensional data modalities such as optical image classification, we show that a low-dimensional embedding of images into a metric space defined by the principal components of the data suffices to produce high-quality predictions from real large-scale survey data. We develop a novel method of GP classification hyperparameter training that scales approximately linearly in the number of image observations, which allows for application of GP models to large-size Hyper Suprime-Cam Subaru Strategic Program data. In our experiments, we evaluate the performance of a principal component analysis embedded GP predictive model against other machine-learning algorithms, including a convolutional neural network and an image photometric morphology discriminator. Our analysis shows that our methods compare favorably with current methods in optical image classification while producing posterior distributions from the GP regression that can be used to quantify object classification uncertainty. We further describe how classification uncertainty can be used to efficiently parse large-scale survey imaging data to produce high-confidence object catalogs.

The solar wind, when measured close to 1 au, is found to flow mostly radially outward. There are, however, periods when the flow makes angles up to 15° away from the radial direction, both in the east–west and north–south directions. Stream interaction regions (SIRs) are a common cause of east–west flow deflections. Coronal mass ejections (CMEs) may be associated with nonradial flows in at least two different ways: (1) the deflection of the solar wind in the sheath region, especially close to the magnetic ejecta front boundary, may result in large nonradial flows; and (2) the expansion of the magnetic ejecta may include a nonradial component, which should be easily measured when the ejecta is crossed away from its central axis. In this work, we first present general statistics of nonradial solar wind flows as measured by STEREO/PLASTIC throughout the first 13 yr of the mission, focusing on solar cycle variation. We then focus on the larger deflection flow angles and determine that most of these are associated with SIRs near solar minimum and with CMEs near solar maximum. However, we find no clear evidence of strongly deflected flows, as would be expected if large deflections around the magnetic ejecta or ejecta with elliptical cross sections with large eccentricities were common. We use these results to develop a better understanding of CME expansion and the nature of magnetic ejecta, and point to shortcomings in our understanding of CMEs.

We study the tidal interaction of galaxies in the Eridanus supergroup, using H i data from the pre-pilot survey of the Widefield ASKAP L-band Legacy All-sky Blind surveY. We obtain optical photometric measurements and quantify the strength of tidal perturbation using a tidal parameter S
sum. For low-mass galaxies of M
* ≲ 109
M
⊙, we find a dependence of decreasing H i to optical disk size ratio with increasing S
sum, but no dependence of H i spectral line asymmetry with S
sum. This is consistent with the behavior expected under tidal stripping. We confirm that the color profile shape and color gradient depend on the stellar mass, but there is an additional correlation of low-mass galaxies having their color gradients within 2R
50 increasing with higher S
sum. For these low-mass galaxies, the dependence of color gradients on S
sum is driven by the color becoming progressively redder in the inner disk when tidal perturbations are stronger. For high-mass galaxies, there is no dependence of color gradients on S
sum, and we find a marginal reddening throughout the disks with increasing S
sum. Our result highlights tidal interaction as an important environmental effect in producing the faint end of the star formation suppressed sequence in galaxy groups.
A Multiparameter Degeneracy in Microlensing Events with Extreme Finite Source Effects
Authors: Johnson Samson A. , Penny Matthew T. , Gaudi B. Scott
Published: March 2022

For microlenses with sufficiently low mass, the angular radius of the source star can be much larger than the angular Einstein ring radius of the lens. For such extreme finite source effect (EFSE) events, finite source effects dominate throughout the duration of the event. Here, we demonstrate and explore a continuous degeneracy between multiple parameters of such EFSE events. The first component in the degeneracy arises from the fact that the directly observable peak change of the flux depends on both the ratio of the angular source radius to the angular Einstein ring radius and the fraction of the baseline flux that is attributable to the lensed source star. The second component arises because the directly observable duration of the event depends on both the impact parameter of the event and the relative lens-source proper motion. These two pairwise degeneracies become coupled when the detailed morphology of the light curve is considered, especially when including a limb-darkening profile of the source star. We derive these degeneracies mathematically through analytic approximations and investigate them further numerically with no approximations. We explore the likely physical situations in which these mathematical degeneracies may be realized and potentially broken. As more and more low-mass lensing events (with ever decreasing Einstein ring radii) are detected with improving precision and increasing cadence from microlensing surveys, one can expect that more of these EFSE events will be discovered. In particular, the detection of EFSE microlensing events could increase dramatically with the Roman Space Telescope Galactic Bulge Time Domain Survey.
Multimessenger Constraints on Magnetic Fields in Merging Black Hole–Neutron Star Binaries

The LIGO–Virgo–KAGRA Collaboration recently detected gravitational waves (GWs) from the merger of black hole–neutron star (BHNS) binary systems GW200105 and GW200115. No coincident electromagnetic (EM) counterparts were detected. While the mass ratio and BH spin in both systems were not sufficient to tidally disrupt the NS outside the BH event horizon, other, magnetospheric mechanisms for EM emission exist in this regime and depend sensitively on the NS magnetic field strength. Combining GW measurements with EM flux upper limits, we place upper limits on the NS surface magnetic field strength above which magnetospheric emission models would have generated an observable EM counterpart. We consider fireball models powered by the black hole battery mechanism, where energy is output in gamma rays over ≲1 s. Consistency with no detection by Fermi-GBM or INTEGRAL SPI-ACS constrains the NS surface magnetic field to ≲1015 G. Hence, joint GW detection and EM upper limits rule out the theoretical possibility that the NSs in GW200105 and GW200115, and the putative NS in GW190814, retain dipolar magnetic fields ≳1015 G until merger. They also rule out formation scenarios where strongly magnetized magnetars quickly merge with BHs. We alternatively rule out operation of the BH-battery-powered fireball mechanism in these systems. This is the first multimessenger constraint on NS magnetic fields in BHNS systems and a novel approach to probe fields at this point in NS evolution. This demonstrates the constraining power that multimessenger analyses of BHNS mergers have on BHNS formation scenarios, NS magnetic field evolution, and the physics of BHNS magnetospheric interactions.
On the Fast Radio Burst and Persistent Radio Source Populations

Published: March 2022

The first fast radio burst (FRB) to be precisely localized was associated with a luminous persistent radio source (PRS). Recently, a second FRB/PRS association was discovered for another repeating source of FRBs. However, it is not clear what makes FRBs or PRS or how they are related. We compile FRB and PRS properties to consider the population of FRB/PRS sources. We suggest a practical definition for PRS as FRB associations with luminosity greater than 1029 erg s−1 Hz−1 that are not attributed to star formation activity in the host galaxy. We model the probability distribution of the fraction of FRBs with PRS for repeaters and nonrepeaters, showing there is not yet evidence for repeaters to be preferentially associated with PRS. We discuss how FRB/PRS sources may be distinguished by the combination of active repetition and an excess dispersion measure local to the FRB environment. We use CHIME/FRB event statistics to bound the mean per-source repetition rate of FRBs to be between 25 and 440 yr−1. We use this to provide a bound on the density of FRB-emitting sources in the local universe of between 2.2 × 102 and 5.2 × 104 Gpc−3 assuming a pulsar-like beamwidth for FRB emission. This density implies that PRS may comprise as much as 1% of compact, luminous radio sources detected in the local universe. The cosmic density and phenomenology of PRS are similar to that of the newly discovered, off-nuclear “wandering” active galactic nuclei (AGN). We argue that it is likely that some PRS have already been detected and misidentified as AGN.
Detecting Preheating in Protoclusters with Lyα Forest Tomography

Published: March 2022

Studies of low-redshift galaxy clusters suggest the intracluster medium (ICM) has experienced nongravitational heating during the formation phase of the clusters. Using simple phenomenological heating prescriptions, we simulate the effect of this preheating of the nascent ICM in galaxy protoclusters and examine its effect on Lyα forest tomographic maps. We analyze a series of cosmological zoom-in simulations of protoclusters within the framework of the Lyα transmission−dark matter (DM) density distribution. We find that the more energy is injected into the proto-ICM at z = 3, the more the distribution at high DM density tilts toward higher Lyα transmission. This effect has been confirmed in both low-resolution simulations adopting a preheating scheme based on entropy floors, as well as in higher-resolution simulations with another scheme based on energy floors. The evolution of the slope of this distribution is shown to vary with redshift. The methodology developed here can be applied to current and upcoming Lyα forest tomographic survey data to help constrain feedback models in galaxy protoclusters.
