Daerah lingkar tambang adalah daerah yang sangat rentan untuk tumbuhnya pengolahan emas dengan menggunakan metode amalgamasi dan sianidasi yang diinisiasi oleh masyarakat pendatang. Oleh fungsi waktu akhirnya masyarakat lokal menguasai teknologi amalgamasi dan sianidasi. Aktifitas ini semakin marak jika bijih emas mempunyai sifat yang cocok untuk diolah dengan amalgamasi dan dilanjutkan dengan sistem sinaidasi. Tambang rakyat ini merupakan isu yang kompleks, dan sama halnya dengan yang terjadi di berbagai negara lain, umumnya orang-orang yang terlibat dalam kegiatan tambang jenis ini di Kao teluk, Malifut dan Kao kabupaten Halmahera Utara merupakan orang-orang yang memiliki tingkat pendidikan yang rendah dan tidak memiliki alternatif mata pencaharian yang lain yang lebih baik. Menjadi tanggungjawab bagi setiap individu dalam masyarakat untuk memberikan pengetahuan pada orang-orang yang terlibat dalam kegiatan tambang rakyat dan tambang skala kecil ini dalam praktik penggunaan merkuri dan sianida dengan aman. Metode ini telah berhasil dengan baik dengan melibatkan lebih dari 900 orang mulai dari anak-anak SD, SMP dan SMA yang orangtuanya/keluarganya terlibat dalam pengolahan emas, Puskemas, Remaja Gereja, Jemaat Gereja, Ibu-ibu Pengajian, Puskemas, Ibu-ibu di enclove pengolahan emas serta penambangan emas itusendiri. Terbentuknya penyuluh-penyuluh untuk pertambangan emas traditional yang mengerti adat dan bahasa lokal sangat penting dan lebih efektif jika didukung bahan-bahan penyuluhan yang kominikatif yang mengacu kepada adat dan kegiatan local.

Published: March 2020

Pit lake merupakan lubang bekas tambang yang dengan sengaja dan/atau secara alami terisi air sehingga membentuk sebuah danau. Dominasi sistem penambangan dengan metode tambang terbuka di dunia menjadikan pit lake akan banyak tersebar di beberapa wilayah bekas penambangan, terutama di daerah tambang yang material batuannya tidak cukup untuk ditimbun kembali ke dalam lubang bekas tambang. Kualitas air pit lake yang ditinggalkan akan beragam, mulai dari yang bersifat asam (pH < 5.0) hingga bersifat basa (alkaline, pH > 8.0), tergantung dari beberapa faktor seperti jenis batuan, kualitas air masukan dan sebagainya. Kualitas air pit lake juga sangat dipengaruhi oleh kondisi hidrologi, kondisi geologi dan iklim di daerah bekas tambang. Pit lake terbagi menjadi 3 jenis yakni danau holomictic, danau meromictic dan danau amictic, sedangkan secara stratifikasi termal, maka pit lake dibagi menjadi lapisan epilimnion, lapisan termoklin atau metalimnion dan lapisan hypolimnion. Pada beberapa negara, pit lake dimanfaatkan untuk beberapa keperluan diantaranya sebagai daerah reservoir air, recovery logamberat, daerah wisata, tempat pelatihan selam dan masih ada beberapa pemanfaatan lainnya. Tulisan ini merupakan kajian teori tentang pit lake dari berbagai sumber yakni buku pegangan, jurnal dan beberapa laporan projek tentang pit lake, sehingga diperoleh gambaran dan juga sebagai dasar dalam merencanakan atau menyusun laporan rencana pascatambang yang menjadikan pit lake sebagai opsi reklamasi.

Penerapan Budaya K3 Pada Petani Karet Di Desa Bentayan & Keluang Kecamatan Tungkal Ilir
Authors: Sitanggang Morlina , Setiawan Heri , Husaini Achmad 
Published: March 2020

Peningkatan kejadian kecelakaan kerja pada petani karet tradisional diDesa Bentayan dan desa Keluang Kecamatan Tungkal Ilir terjadi karena kurangnya pengetahuan dan rendahnya kesadaran tentang pentingnya menerapkan prinsip keselamatan dan kesehatan kerja di ladang karet. Berdasarkan hasil observasi dan wawancara dengan masyarakat Desa Bentayan dan Keluang yang mayoritas bekerja sebagai petani karet alam maka didapatkan data bahwa petani karet mengalami masalah kesehatan, utamanya gangguan saluran pernafasan, gangguan kulit dengan beberapa diantaranya mengalami gangguan pencernaan, hal ini terjadi karena petani kurang memahami tentang keselamatan dan kesehatan kerja dikarenakan rendahnya pengetahuan mereka serta belum adanya penyuluhan/pembinaan keselamatan dan kesehatan dalam bekerja. Metode Kegiatan dilaksanakan dalam bentuk penyuluhan kesehatan tentang keselamatan kerja, bahaya dan resiko penyakit akibat pekerjaan, pemeriksaan kesehatan resiko penyakit pada petani karet, SOP penggunaan APD di ladang karet dan pelatihan tata cara pemakaian APD bagi para petani/ pekerja diladang karet. Dari hasil workshop luaran yang diharapkan adalah peningkata pemahaman mitra berkaitan dengan Budaya Kesehatan dan Keselamatan Kerja (K3) dan penerapannya. Dari hasil pretest dan posttest diperoleh bahwa terjadi pengingkatan pemahaman mengenai budaya K3 pada nilai signifikasi sebesar 0.000. Selain itu dari pemeriksaan kesehatan dapat disimpulkan bahwa secara umum mitra di kedua desa tidak memiliki masalah serius berkaitan dengan status kesehatan. Namun, ada beberapa penyakit yang perlu mendapat perhatian diantaranya: satu mitra mengalami masalah kulit, dan 12 peserta mengalami keluhan nyeri dada dan sesak nafas, dan tiga orang mengeluh jatung berdebar-debar dan mudah capek disertai sesak nafas.
Sun-like Stars Shed Light on Solar Climate Forcing
Authors: Judge P. G. , Egeland R. , Henry G. W. 
Published: March 2020

Abstract
Recently published precise stellar photometry of 72 Sun-like stars obtained at the Fairborn Observatory between 1993 and 2017 is used to set limits on the solar forcing of Earth’s atmosphere of ±4.5 W m−2 since 1750. This compares with the +2.2 ± 1.1 W m−2 IPCC estimate for anthropogenic forcing. Three critical assumptions are made. In decreasing order of importance they are: (a) most of the brightness variations occur within the average time series length of ≈17 yr; (b) the Sun seen from the ecliptic behaves as an ensemble of middle-aged solar-like stars; and (c) narrowband photometry in the Strömgren b and y bands are linearly proportional to the total solar irradiance. Assumption (a) can best be relaxed and tested by obtaining more photometric data of Sun-like stars, especially those already observed. Eight stars with near-solar parameters have been observed from 1999, and two since 1993. Our work reveals the importance of continuing and expanding ground-based photometry, to complement expensive solar irradiance measurements from space.
Growth of Supermassive Black Hole Seeds in ETG Star-forming Progenitors: Multiple Merging of Stellar Compact Remnants via Gaseous Dynamical Friction and Gravitational-wave Emission
Authors: Boco L. , Lapi A. , Danese L. 
Published: March 2020

Abstract
We propose a new mechanism for the growth of supermassive black hole (BH) seeds in the star-forming progenitors of local early-type galaxies (ETGs) at z ≳ 1. This envisages the migration and merging of stellar compact remnants (neutron stars and stellar-mass BHs) via gaseous dynamical friction toward the central high-density regions of such galaxies. We show that, under reasonable assumptions and initial conditions, the process can build up central BH masses of the order of 104–106
M
⊙ within some 107 yr, so effectively providing heavy seeds before standard disk (Eddington-like) accretion takes over to become the dominant process for further BH growth. Remarkably, such a mechanism may provide an explanation, alternative to super-Eddington accretion rates, for the buildup of billion-solar-massed BHs in quasar hosts at z ≳ 7, when the age of the universe ≲0.8 Gyr constitutes a demanding constraint; moreover, in more common ETG progenitors at redshift z ∼ 2–6, it can concur with disk accretion to build such large BH masses even at moderate Eddington ratios ≲0.3 within the short star formation duration ≲Gyr of these systems. Finally, we investigate the perspectives to detect the merger events between the migrating stellar remnants and the accumulating central supermassive BH via gravitational-wave emission with future ground- and space-based detectors such as the Einstein Telescope and the Laser Interferometer Space Antenna.

Abstract
During its first solar encounter, the Parker Solar Probe (PSP) acquired unprecedented up-close imaging of a small coronal mass ejection (CME) propagating in the forming slow solar wind. The CME originated as a cavity imaged in extreme ultraviolet that moved very slowly (<50 km s−1) to 3–5 solar radii (R
⊙), where it then accelerated to supersonic speeds. We present a new model of an erupting flux rope (FR) that computes the forces acting on its expansion with a computation of its internal magnetic field in three dimensions. The latter is accomplished by solving the Grad–Shafranov equation inside two-dimensional cross sections of the FR. We use this model to interpret the kinematic evolution and morphology of the CME imaged by PSP. We investigate the relative role of toroidal forces, momentum coupling, and buoyancy for different assumptions on the initial properties of the CME. The best agreement between the dynamic evolution of the observed and simulated FR is obtained by modeling the two-phase eruption process as the result of two episodes of poloidal flux injection. Each episode, possibly induced by magnetic reconnection, boosted the toroidal forces accelerating the FR out of the corona. We also find that the drag induced by the accelerating solar wind could account for about half of the acceleration experienced by the FR. We use the model to interpret the presence of a small dark cavity, clearly imaged by PSP deep inside the CME, as a low-density region dominated by its strong axial magnetic fields.

Abstract
Field and plasma variations during the first perihelion pass of the Parker Solar Probe (PSP) from 53 into 35 solar radii (R

S
) from the Sun and over a frequency range in the spacecraft frame (f
SC) from 0.0002 to 0.2 Hz are decomposed into constituent magnetohydrodynamic (MHD) modes. The analysis operates on measurements of the MHD variables recorded between impulsive, large amplitude rotations of the magnetic field to reveal the dominance of a broad spectrum of shear Alfvén waves propagating antiparallel (backward) to the background magnetic field (
B

0) with a significant fraction of spectral energy density in the backward slow mode and, to a lesser extent, fast mode waves. While all three MHD modes provide Poynting flux directed outward from the Sun the impulsive rotations of B
0 from inward to outward radial orientations provide intervals of outward and inward propagation in the plasma frame, respectively. This morphology is suggestive of outward wave propagation from a near Sun source along kinked field lines that provide alternating radial B
0 orientations as the magnetic field is advected with the flow over the spacecraft. Shear Alfvén and slow mode spectral energy density is generally largest within intervals of reversed radial B
0, while the fast mode tends to occur outside these regions, albeit with lower intensity. The spectral energy density in the forward propagating modes increases with f
SC above 0.01 Hz, which is suggestive of back scatter in the plasma frame of the dominant backward modes from the radial field reversals and associated inhomogeneities of the embedded plasmas.

Abstract
We present a technique for deriving the temperature anisotropy of solar wind protons observed by the Parker Solar Probe (PSP) mission in the near-Sun solar wind. The radial proton temperature measured by the Solar Wind Electrons, Alphas, and Protons (SWEAP) Solar Probe Cup is compared with the orientation of local magnetic field measured by the FIELDS fluxgate magnetometer, and the proton temperatures parallel and perpendicular to the magnetic field are extracted. This procedure is applied to different data products, and the results are compared and optimum timescales for data selection and trends in the uncertainty in the method are identified. We find that the moment-based proton temperature anisotropy is more physically consistent with the expected limits of the mirror and firehose instabilities, possibly because the nonlinear fits do not capture a significant non-Maxwellian shape to the proton velocity distribution function near the Sun. The proton beam has a small effect on total proton temperature anisotropy owing to its much smaller density relative to the core compared to what was seen by previous spacecraft farther from the Sun. Several radial trends in the temperature components and the variation of the anisotropy with parallel plasma beta are presented. Our results suggest that we may see stronger anisotropic heating as PSP moves closer to the Sun, and that a careful treatment of the shape of the proton distribution may be needed to correctly describe the temperature.
Symptomatic Intratendinous Ganglion Cyst of the Patellar Tendon
Authors: Jose Jean , O’Donnell Kevin , Lesniak Bryson 
Published: March 2020

Ganglion cysts have been previously described throughout the body, most commonly about the wrist, hand, knee, ankle, and feet. When symptomatic, they may interfere with joint mechanics, resulting in snapping, catching, and locking. Intratendinous ganglion cysts lack a synovial epithelial lining and are thought to develop from the mucoid degeneration of connective tissue caused by chronic irritation, chronic repetitive injury, and chronic ischemia. On magnetic resonance imaging, ganglion cysts originating from tendons, ligaments, tendon sheaths, menisci, or joint capsules appear as well-defined lobulated masses that follow simple or complex fluid signal intensity on all pulse sequences, with enhancing walls and internal septations on post-contrast images. There may be appreciable degeneration and partial tearing of the structure of origin, particularly if associated with tendons. On ultrasonography, they present as hypoechoic masses, with internal septations and lobulations of varying sizes, without significant vascularity on power or color Doppler sampling. A thin fluid neck extending from the structure of origin (tail sign), when present, is a reliable sign of a ganglion cyst.
This article describes a sonographically guided technique to treat symptomatic ganglion cysts within the patellar tendon. Complete evacuation of the ganglion cyst, with disappearance of the tail sign, is considered the determining factor for a successful procedure. A similar technique can be used for the treatment of other symptomatic intratendinous ganglion cysts elsewhere in the body. To our knowledge, symptomatic intratendinous ganglion cysts within the patellar tendon and their treatment have not been previously reported.
Occupational Therapy Practice Guidelines for Older Adults With Low Vision
Authors: Kaldenberg Jennifer , Smallfield Stacy 
Published: March 2020

Abstract
Importance: The aging of the population is generating increased demand for occupational therapy practitioners to address the occupational performance of those experiencing low vision.
Objective: This Practice Guideline, which is informed by systematic reviews on interventions for older adults with low vision, is meant to serve as a reference for occupational therapy practitioners to guide best practice in service delivery, improve quality of care, enhance consumer satisfaction, and justify occupational therapy services to external stakeholders. Interventions included in this guideline address performance of activities of daily living (ADLs) and instrumental activities of daily living (IADLs), reading, and leisure and social participation.
Method: We examined, synthesized, and integrated the results of three systematic reviews into recommendations for practice, education, and research.
Results: Thirty-eight articles were included in the systematic reviews, which served as the basis for clinical recommendations. A case study describes translation and application of the recommendations to clinical practice.
Conclusions and Recommendations: Strong evidence supports the role of occupational therapy for older adults with low vision. On the basis of the evidence, we recommend routine use of low vision rehabilitation for ADL and IADL impairments, multicomponent interventions to improve ADL and IADL performance and leisure and social participation, stand-based electronic magnification to enhance reading, and visual skills training to enhance reading for clients with a central field impairment. We recommend using client-centered problem-solving training to enhance ADL and IADL performance, reading, and leisure and social participation. Mainstream technology may be considered for use on a case-by-case basis to enhance reading performance. Finally, adapted tango may be considered for use on a case-by-case basis to enhance ADL and IADL performance and leisure and social participation.
What This Article Adds: This Practice Guideline provides a summary of the current evidence supporting occupational therapy intervention for older adults with low vision. It summarizes the emerging literature supporting the use of mainstream technology and provides additional support for the use of multicomponent intervention strategies.
Genotype and Phenotype Concordance for Pharmacogenetic Tests Through Proficiency Survey Testing
Authors: Moyer Ann M. , McMillin Gwendolyn A. , Long Thomas A. , Gandhi Manish J. , Mao Rong , Smock Kristi J. , Halley Jaimie G. , Weck Karen E. 
Published: March 2020

Context.—
As pharmacogenetic testing is incorporated into routine care, it is essential for laboratories to provide accurate and consistent results. Certified laboratories must successfully complete proficiency testing.

Objectives.—
To understand and examine trends in participation and performance of laboratories participating in the College of American Pathologists pharmacogenetic proficiency testing surveys.

Design.—
Results from College of American Pathologists pharmacogenetic proficiency testing challenges from 2012 through 2017 were reviewed for concordance with expected genotype and phenotype for each sample (intended responses).

Results.—
Laboratories correctly reported results for 96.7% to 100% of samples with no variants. Excluding CYP2D6, laboratories correctly detected and reported variant alleles for each gene (93.7%–99.2% correct). CYP2D6 showed lower concordance, with 83.1% of laboratories reporting the intended genotype across all samples; however, in many cases, the laboratories that did not report a variant allele did not test for that allele. Among laboratories reporting the intended genotype, most successfully reported the intended phenotype (85.9%–99.0%).

Conclusions.—
Although laboratories are generally performing well, there is room for additional improvement, particularly for challenging genes, such as CYP2D6. Efforts in the field of pharmacogenomics to recommend alleles that should be included in clinical tests, identify reference materials, and standardize translation from genotype to phenotype may address some of the remaining variability in results.
