Strategi Pemenuhan Angka Kredit Pejabat Fungsional Pengelola Pengadaan Barang Jasa pada Balai Pelaksana Pemilihan Jasa Konstruksi
Authors: Nugroho Sunu Ardhi 
Published: November 2022

Balai Pelaksana Pemilihan Jasa Konstruksi (BP2JK) di Kementerian Pekerjaan Umum dan Perumahan Rakyat (PUPR) mendapatkan amanat dari Permen PUPR Nomor 16 Tahun 2020 untuk melaksanakan tugas pelayanan pengadaan barang/jasa konstruksi dan tugas lainnya di bidang pengadaan barang/jasa konstruksi yang ditetapkan oleh Direktur Jenderal Bina Konstruksi. Dalam pelaksanaan tugasnya, BP2JK yang dibentuk di 34 Provinsi didukung oleh Sumber Daya Manusia (SDM) yang menduduki jabatan fungsional Pengelola Pengadaan Barang/Jasa dan personil lainnya. Berdasarkan Permenpan RB Nomor 20 Tahun 2020, Jabatan Fungsional Pengelola Pengadaan Barang Jasa memiliki 4 tugas jabatan yang dapat diklaim sebagai angka kredit, yaitu meliputi perencanaan pengadaan, pemilihan penyedia, pelaksanaan kontrak dan pengelolaan pengadaan barang/jasa secara swakelola. Dalam pelaksanaan tugas sebagai Pejabat Fungsional di BP2JK, Pengelola Pengadaan Barang/Jasa memiliki tantangan dalam pengumpulan angka kredit karena pelaksanaan tugas dan fungsi BP2JK masih terbatas dalam tugas jabatan pemilihan penyedia barang/jasa, khususnya hanya pelaksanaan Tender/Seleksi/Penunjukkan Langsung yang dilaksanakan oleh Pokja Pemilihan. Tugas dan fungsi BP2JK masih terbatas dan belum dapat mengakomodasi tugas jabatan di bidang perencanaan pengadaan, pelaksanaan kontrak dan pengelolaan pengadaan barang/jasa secara swakelola yang kewenangannya masih berada di unit organisasi teknis. Selain tantangan di bidang tugas jabatan, terdapat perbedaan beban kerja dan jumlah paket pada BP2JK di setiap provinsi yang berpotensi menyebabkan pemenuhan angka kredit minimal bagi Pejabat Fungsional Pengelola Pengadaan Barang/Jasa di BP2JK tidak tercapai. Melalui penelitian menggunakan metode kualitatif dengan studi kasus di BP2JK Wilayah Gorontalo, dihasilkan konsep strategi pemenuhan angka kredit bagi Pejabat Fungsional Pengelola Pengadaan Barang/Jasa di BP2JK Wilayah Gorontalo dan diharapkan dapat menjadi referensi dan diimplementasikan di BP2JK lain atau unit kerja dengan profil dan kondisi yang sama.

Published: November 2022

In this paper, a new electrochemical sensor was reported for the determination of amaranth in drink soft. In this sensor, activated carbon-Co3O4 nanocomposite (AC-Co3O4) was employ­ed as electrode modifying materials. The introduction of high pores to the activated carbon not only can in favor of more amaranth molecules adsorbed to the surface of the working electrode through the pores, but also may benefit fast electron diffusion in the electro­chemical detection process. So, the AC-Co3O4 modified electrode enhanced its electro­chemical signal obviously in the determination of amaranth in drink soft and exhibited a wider linear response ranging from 0.1 to 215.0 µM with a low detection limit of 10.0 nM (based on 3Sb/m). This work offers a new route in developing new electro­chemical sensors for the determination of colorants additives and other hazard components in drink soft.

Remote sensing of inland waters is challenging, but also important, due to the need to monitor the ever-increasing harmful algal blooms (HABs), which have serious effects on water quality. The Ocean and Land Color Instrument (OLCI) of the Sentinel-3 satellites program is capable of providing images for the monitoring of such waters. Atmospheric correction is a necessary process in order to retrieve the desired surface-leaving radiance signal and several atmospheric correction methods have been developed through the years. However, many of these correction methods require programming language skills, or function as commercial software plugins, limiting their possibility of use by end users. Accordingly, in this study, the free SNAP software provided by the European Space Agency (ESA) was used to evaluate the possible differences between a partial atmospheric correction method accounting for Rayleigh scattering and a full atmospheric correction method (iCOR), applied on Sentinel-3 OLCI images of a shallow, highly eutrophic water reservoir. For the complete evaluation of the two methods, in addition to the comparison of the band reflectance values, chlorophyll (CHL) and cyanobacteria (CI) indices were also calculated and their values were intercompared. The results showed, that although the absolute values between the two correction methods did not coincide, there was a very good correlation between the two methods for both bands’ reflectance (r > 0.73) and the CHL and CI indices values (r > 0.95). Therefore, since iCOR correction image processing time is 25 times longer than Rayleigh correction, it is proposed that the Rayleigh partial correction method may be alternatively used for seasonal water monitoring, especially in cases of long time-series, enhancing time and resources use efficiency. Further comparisons of the two methods in other inland water bodies and evaluation with in situ chlorophyll and cyanobacteria measurements will enhance the applicability of the methodology.

ImportanceThere are more than 140 million annual visits to emergency departments (EDs) in the US. The role of EDs in providing care at or near the end of life is not well characterized.ObjectiveTo determine the frequency of death in the ED or within 1 month of an ED visit in an all-age, all-payer national database.Design, Setting, and ParticipantsThe retrospective cohort study used patient-level data from the nationally representative Optum clinical electronic health record data set for 2010 to 2020. Data were analyzed from January to March 2022.ExposuresAge, Charlson Comorbidity Index (CCI), and year of ED encounter.Main Outcomes and MeasuresThe primary outcome was death in the ED, overall and stratified by age, CCI, or year. A key secondary outcome was death within 1 month of an ED encounter. We extrapolated to make national estimates using US Census and Nationwide Emergency Department Sample data.ResultsAmong a total of 104 113 518 individual patients with 96 239 939 ED encounters, 205 372 ED deaths were identified in Optum, for whom median (IQR) age was 72 (53 to &amp;gt;80) years, 114 582 (55.8%) were male, and 152 672 (74.3%) were White. ED death affected 0.20% of overall patients and accounted for 0.21% of ED encounters. An additional 603 273 patients died within 1 month of an ED encounter. Extrapolated nationally, ED deaths accounted for 11.3% of total deaths from 2010 to 2019, and 33.2% of all decedents nationally visited the ED within 1 month of their death. The proportion of total national deaths occurring in the ED decreased by 0.27% annually (P for trend = .003) but the proportion who died within 1 month of an ED visit increased by 1.2% annually (P for trend &amp;lt; .001). Compared with all ED encounters, patients with visits resulting in death were older, more likely to be White, male, and not Hispanic, and had higher CCI. Among ED encounters for patients aged older than 80 years, nearly 1 in 12 died within 1 month.Conclusions and RelevanceThis retrospective cohort study found deaths during or shortly after ED care were common, especially among patients who are older and with chronic comorbidities. EDs must identify patients for whom end-of-life care is necessary or preferred and be equipped to deliver this care excellently.
Information loss, contextual information, and distinctiveness influence how well novice analysts discriminate fingerprints
Authors: Marcon Zabecki Jessica , Quigley‐McBride Adele , Meissner Christian A. 
Published: November 2022

AbstractAcross two experimental studies, we investigated the role of information loss, contextual information, and distinctive features of fingerprints on novice's ability to judge whether two fingerprints came from the same source. Distinctive fingerprints resulted in more accurate decisions. Information loss diminished performance on the comparison task, likely due to the loss of distinctive features. When people received contextual information from a fingerprint matching software (Automated Fingerprint Identification System or AFIS) suggesting that the two fingerprints were from the same source, they were less accurate and more biased to render a “same source” decision. These findings suggest that analysts should evaluate the characteristics of a fingerprint prior to engaging in a comparison task, and that fingerprints lacking information, particularly distinctive characteristics, should be more cautiously evaluated.

Published: November 2022

AbstractHierarchical vasculature reconstruction is fundamental for tissue regeneration. The regeneration of functional vascular network requires a proper directional guidance, especially in case of large‐size defects. To provide the “running track” for vasculature, a leaf‐vein mimetic membrane using soft and elastic poly(lactide‐co‐propylene glycol‐co‐lactide) dimethacrylate is developed. Engraved with an interconnected and perfusable leaf‐vein micropattern, the membrane can guide human umbilical vein endothelial cells (HUVECs) to form vasculature in vitro. In particular, the “running track” upregulates the angiogenesis‐related gene expression and promotes the HUVECs to differentiate into tip cells and stalk cells via tuning vascular endothelial growth factor receptor 2 signaling transduction. As a proof of concept, its revascularization capability using a rat calvarial defect model in vivo is evaluated. The in vivo results demonstrate that the leaf‐vein engraved membrane accelerates the formation and maturation of vasculature, leading to a hierarchical blood vessel network. With the superior pro‐vasculature property, it is believed that the leaf‐vein engraved membrane is not only an ideal candidate for the reconstruction of calvarial vasculature but also a promising solution for more complicated vasculature reconstruction, such as muscle, skin, and heart.

Published: November 2022

AbstractNanoscintillators (nanocrystals with X‐ray scintillation performance) lay a fundamental for their practical application in high‐resolution and low‐dose medical examination due to their excellent photoelectric properties. The optical properties and scintillation performance of nanocrystals (NCs) can be significantly affected by adjusting their size. However, the mechanism of the size effect of NCs on optical properties and X‐ray scintillation performance has not been revealed. Here, a mathematical model and experimental results are combined to demonstrate the impact of the size of NCs on their scintillation performance. The results show that the surface area and volume of NCs exhibit a positive and negative impact on the change rate of the bandgap, respectively. This model further verifies that the photoluminescence quantum yield of NCs decreases with the decrease of their size, and their light yield is remarkably affected by the size of NCs. Overall, this work provides some enlightenment for researchers to design NCs with the appropriate size for their applications in high‐performance X‐ray scintillation.
Phase‐Transition‐Triggered Optical Switching for Multistage Information Encryption/Decryption

Published: November 2022

AbstractIt remains challenging to enable the optical switching for safety‐improved information encryption/decryption on a gel platform. Herein, a water swelling‐induced optical‐switching strategy is reported that can achieve multistage information encryption/decryption on an organohydrogel surface. Cationic moieties of methacrylamido propyl trimethyl ammonium chloride (MPTAC) and hydrophobic fluorophores of (2‐(4‐vinylphenyl) ethene‐1,1,2‐triyl) tribenzene (TPE) are copolymerized into hydrophilic polyacrylamide network. The cationic moieties are capable of increasing the water swelling ability of the network, and the fluorophores endow the network with weak blue fluorescence. Upon low swelling with water (swelling ratio in weight < 50), hydrophobic fluorophores of TPE aggregate to enhance the fluorescence under ultraviolet light. This process is accompanied with the phase transition of organohydrogel into a non‐transparent state. After being saturated with water, the fluorescence disappears and the organohydrogel returns to the transparent state. Such water swelling‐induced optical switching can be used for multistage information encryption/decryption with improved safety. Various information patterns are created on the surface of organohydrogel by laser cutting to demonstrate the complex information encryption/decryption processes. This strategy not only provides a meaningful inspiration for information encryption/decryption but also enables an optical‐switching platform for potential anti‐counterfeiting and displaying.

Published: November 2022

AbstractEffective diagnosis and treatment of cancer is still a great challenge to modern medicine. The advent of immunotherapy is revolutionizing the field of cancer research while drug toxicity and low responsive rates have become the most serious concerns in current treatment regimes. Dendritic cells (DCs) are the strongest antigen‐presenting immune cells and play an important role in the initiation and regulation of the immune response. They can engulf a variety of foreign substances, including cell lysates and nucleic acids, and present antigens to activate the immune system. Some nanomaterials in vitro activation systems for DCs provide new ideas for immune‐related therapies for tumors. Among these, magnetic nanoparticles (MNPs) have gradually become a major focus of basic scientific research and clinical treatment due to their advantages of good biocompatibility, low toxic side effects, and high ability to respond to external stimulus. The emergence of MNPs provides a novel, safe, and effective way to enhance the anti‐tumor immune response. In this review, the application of MNPs as platform materials combined with DC immunotherapy is discussed, with the intention of providing a reference for future disease immunotherapy.

Published: November 2022

AbstractFarmers in Mediterranean climate regions are increasingly growing canola (Brassica napus L.) in wheat (Triticum aestivum L.)‐based systems to break soil‐borne pathogen disease cycles, control weeds, and enhance crop marketing opportunities. A 6‐year rainfed cropping systems experiment was conducted near Ritzville, Washington USA from 2015 to 2021. The objective was to compare performance of winter and spring canola, winter triticale (× Triticosecale Wittmack) (WT), and winter wheat (WW) and measure their effects on soil water dynamics and subsequent performance of spring wheat (SW). Overwinter soil water gain in canola stubble was significantly reduced compared to water gain in WT and WW stubble. The more winter precipitation, the greater the differences in soil water among treatments in early spring. There was a trend in all years for diminished overwinter soil water gain in canola stubble. Averaged over years, grain yield of SW was 1940, 2340, and 2210 kg/ha grown on canola, WT, and WW stubble, respectively (p = 0.045). Coefficients of determination from regression analysis conducted each year showed a high correlation between water content in the 180 cm profile in early spring and SW grain yield, except in one year of extreme drought. This paper provides a first report in a Mediterranean climate region of decline in wheat grain yield after canola versus after a cereal crops, primarily due to reduced overwinter soil water storage.
Evolution in the clinic: Maladaptive units and “minor anomalies”
Authors: Carey John C. , Opitz John M. 
Published: November 2022

AbstractIt is here argued that the application of the term “minor anomalies” is often imprecise and likely outdated. In the past, the designation was used indiscriminately to refer to a great variety of unrelated morphogenetic phenomena. Also, the term does not discriminate between mildqualitativedefects of development (mild malformations) andquantitativevariants of normal structure. The human face was formed by natural and sexual selection. Morphological and morphogenetic analyses have shown that the human face with its skin, muscles, nerves, arteries, veins, glands, and lymphatics is a complex structure made up of progeny of ectoderm and mesoderm. Holoprosencephaly demonstrates graphically how these embryonic derivatives fit together sequentially. These derivatives are theadaptive unitsof the human organism, the result of stringent evolutionary forces uniting essential function to a minimum of structure. Before an “unusual” facial appearance is diagnosed as “abnormal”, phenotype analysis is required to determine if there is afamily resemblanceor if it is apleiotropicstructure. The facial structures of chimps and humans arehomologousby virtue of descent from a common ancestor (Darwin, 1859). Differences in the appearance of these species reflect adaptive divergence over some 6–7 million years of evolution while retaining over 98–99% genetic identity. Both species may develop Down syndrome, evidence of similarly retained developmental plasticity. It has occurred to us that Dobzhansky's axiom (“Nothing in biology makes sense except in the light of evolution”) applies not only to genetics, but to all of medicine.

AbstractOften the reactor or the reaction medium temperature is reported in the field of heterogeneous catalysis, even though it could vary significantly from the reactive catalyst temperature. The influence of the catalyst temperature on the catalytic performance and vice versa is therefore not always accurately known. We here apply EuOCl as both solid catalyst and thermometer, allowing for operando temperature determination. The interplay between reaction conditions and the catalyst temperature dynamics is studied. A maximum temperature difference between the catalyst and oven of +16 °C was observed due to the exothermicity of the methane oxychlorination reaction. Heat dissipation by radiation appears dominating compared to convection in this set‐up, explaining the observed uniform catalyst bed temperature. Application of operando catalyst thermometry could provide a deeper mechanistic understanding of catalyst performances and allow for safer process operation in chemical industries.

AbstractBiological ion channels existing in organisms are critical for many biological processes. Inspired by biological ion channels, the heterogeneous electrospinning nanofiber membranes (HENM) with functional ion channels are constructed by electrospinning technology. The HENM successfully realizes ion‐gating effects, which can be used for tunable energy conversions. Introduction of pyridine and carboxylic acid groups into the HENM plays an important role in generating unique and stable ion transport behaviors, in which gates become alternative states of open and close, responding to symmetric/asymmetric pH stimulations. Then we used the HENM to convert osmotic energy into electric energy which reach a maximum value up to 12.34 W m−2 and the output power density of HENM‐based system could be regulated by ion‐gating effects. The properties of the HENM provide widespread potentials in application of smart nanofluidic devices, energy conversion, and water treatment.
In Situ Enzyme Immobilization by Covalent Organic Frameworks
Authors: Sicard Clémence 
Published: November 2022

AbstractEnzyme immobilization is a widely reported method to favor the applicability of enzymes by enhancing their stability and re‐usability. Among the various existing solid supports and immobilization strategies, the in situ encapsulation of enzymes within crystalline porous matrices is a powerful tool to design biohybrids with a stable and protected catalytic activity. However, to date, only a few metal–organic frameworks (MOFs) and hydrogen‐bonded organic frameworks (HOFs) have been reported. Excitingly, for the first time, Y. Chen and co‐workers expanded the in situ bio‐encapsulation to a new class of crystalline porous materials, namely covalent organic frameworks (COFs). The enzyme@COF materials not only exhibited high enzyme loading with minimal leaching, high catalytic activity and selectivity, chemical and long‐term stability and recyclability but could also be scaled up to a few grams. Undoubtedly, this work opens new striking opportunities for enzymatic immobilization and will stimulate new research on COF‐based matrices.
Cobalt‐Catalyzed Regiodivergent Double Hydrosilylation of Arylacetylenes

Published: November 2022

AbstractDouble hydrosilylation of alkynes represents a straightforward method to synthesize bis(silane)s, yet it is challenging if α‐substituted vinylsilanes act as the intermediates. Here, a cobalt‐catalyzed regiodivergent double hydrosilylation of arylacetylenes is reported for the first time involving this challenge, accessing both vicinal and geminal bis(silane)s with exclusive regioselectivity. Various novel bis(silane)s containing Si−H bonds can be easily obtained. The gram‐scale reactions could be performed smoothly. Preliminarily mechanistic studies demonstrated that the reactions were initiated by cobalt‐catalyzed α‐hydrosilylation of alkynes, followed by cobalt‐catalyzed β‐hydrosilylation of the α‐vinylsilanes to deliver vicinal bis(silane)s, or hydride‐catalyzed α‐hydrosilylation to give geminal ones. Notably, these bis(silane)s can be used for the synthesis of high‐refractive‐index polymers (nd up to 1.83), demonstrating great potential utility in optical materials.
