Published: June 2022

Guna mencapai bauran energi nasional tahun 2025 perlu akselerasi pengembangan kapasitas energi baru terbarukan. Salah satu energi baru terbarukan yang berpotensi dikembangkan di Indonesia adalah biomassa untuk bahan bakar, dengan cara co-firing. Biomassa bisa menjadi energi alternatif yang efektif, guna meminimaslir penggunaan bahan bakar fosil. Biomassa bisa dicampurkan kedalam bunker batubara, campuran bahan bakar tersebut di alirkan menuju ruang bakar atau furnace. Beberapa keuntungan penggunaan biomasa pada PLTU antara lain investasi relatif lebih rendah dan dampak lingkungan lebih baik jika dibandingkan dengan yang 100% batubara. Serbuk kayu ini merupakan limbah produksi karena tidak dapat menghasilkan produk (output) yang bernilai tinggi dari segi ekonomi. Sawdust/Serbuk kayu sisa hasil pengerajin. Perhitungan tara kalor dengan metode input-output, dilakukan dengan cara menghitung total konsumsi bahan bakar dalam satuan kg/jam, dikalikan dengan nilai kalor rata-rata batubara selama pengujian kemudian dibagi dengan rata-rata daya yang dihasilkan dalam satuan kWh/jam, sehingga didapatkan energi. Kesimpulannya Penggunaan subtitusi pembakaran dengan cara menambahkan sawdust pada boiler dengan blending 95% Batubara dan 5% sawdust tidak ada perbedaan signifikan, hasil perhitungan heat rate metode input-output nilai GPHR coal firing 2649 kCaI/kWh, sementara nilai GPHR co-firing yaitu 2705 kCal/kWh, dengan penurunan kWh produksi gross sebesar 1% pada saat co-firing. Nilai SFC relatif sama yaitu SFC coal firing adalah 0,617 dan SFC co-firing adalah 0,621. Dari hasil perhitungan heat rate metode heat loss didapatkan efisiensi boiler saat coal firing adalah 84,34% sementara saat co-firing adalah 84,72%. Nilai GPHR pada saat coal firing adalah sebesar 2.668,37 kCaI/kWh dan saat co-firing adalah 2.688,16 kCal/kWh.

Dealing with pandemics has never been a new issue, seen from the perspective of the history of mankind. It was a manifestation of l’histoire se répète. As an example, a few centuries prior to the Black Death and Cholera Outbreak, Galvao wrote that a respiratory disease had broken out in Ternate around 1553, while De Clercq mentioned a deadly plague in Bacan throughout 1706-1709. Traditionally, these issues were treated as a result of badly conducted supernatural rituals. They opted for herbal treatments, and exorcism, and even migrated to the hinterland as an act of self-quarantine. Today, COVID-19 has become a global pandemic and reached the islands of North Maluku province, with Ternate as the epicentrum of the outbreak. However, there has been a resolution, which facilitates another traditionally crafted effort, such as Liliyan, Barifola, and Rera, based on the oral tradition mentioned in Dora Bololo. We seek to discover how far cultural aspect would affect the economic and social life of the locals, as well as in what domain tradition and local practice should contribute to the current situation. Thus, this research aims to understand and analyze such a combination of traditionally generated solutions within a current scientific framework, especially on how history, anthropology, as well as archival, and memory study could understand the living aspect of the locals and therefore apply Vansina’s (1985) approach in oral tradition as historical sources.

Published: June 2022

The study of manuscripts on religious moderation, especially those related to counter extremist and Wahhabi doctrines, missed a manuscript written in 1926. The manuscript was written by Kiai Muhammad Dimyati bin Abdul Karim as-Surakarta, under the title Lawāmi'ul Burhān wa Qawāṭi'ul Bayān. The main motivation in writing the manuscript was to educate people so that they are not influenced by wahhabism. This research is a study of manuscript Lawāmi'ul Burhān wa Qawāṭi'ul Bayān by Kiai Muhammad Dimyati. The manuscript has perspective about the importance of rising together against the narrow Islam of Wahhabism; Islam suppresses local cultural expressions, feels right about himself, seems unfriendly and different, and also downplays the role of women. This article finds that Kiai Muhammad Dimyati bin Abdul Karim has conducted a critical study of the Wahhabi doctrine, which according to him is mono-perspective and does not tolerate differences in interpreting Islamic law (mazhab).

Published: June 2022

Abstract
The use of Atmospheric Plasma Spraying (APS) and yttria stabilized zirconia (YSZ) nanostructured coatings has been applied to the bond layer of NiCrAlY coated engine cylinder heads, pistons, and valve substrates. Thermal barrier coatings (TBCs) have been utilized to increase the engine performance in the design of combustion chamber components for internal combustion engines. ASTM-C-633-01 standard has been employed to conduct the bonding strength testing. It was also considered and directed to estimate the coating’s thermal performance by evaluating its insulation value and conducting a thermal insulation durability assessment. Field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD) were used to look at the nano powders and coatings’ microstructures and phase compositions. In YSZ, it was discovered that the topcoat of samples had a tri-modal pattern of nano sized particles engaged by the powder, micro-columnar grains generated from the re-solidification of the molten part of the powder, and almost equiaxed grains, which were a unique construction feature. The results demonstrated the creation of nano zones in one of three nanostructured coating zones and improved the top coating properties, including bonding strength and thermal insulation capacity. The high temperature of the diesel engine caused fatigue failure in the intake and exhaust valves.

Abstract

Objectives
To detect common congenital disorders in Holt-Oram syndrome.

Case presentation
We present a case of a 32 years old primigravida pregnant woman affected by Holt-Oram syndrome referred to our institution for second trimester routine anatomy scan. The ultrasound reported a bilateral aplasia radii, slightly curved ulna and bilateral twisted hand with four digital rays. A significant enlargement of the right atrium without tricuspid regurgitation was also detected. The patient refused the amniocentesis and the postnatal evaluation confirmed the diagnosis of Holt-Oram syndrome.

Conclusions
Holt-Oram syndrome is an autosomal dominant genetic condition. It is characterized by abnormalities in the bones of the upper limb and congenital heart malformation. The mutation can be inherited, but most cases result from a new mutation in patients without family history of the disorder.
System and eco-material design based on slow-release ferrate(vi) combined with ultrasound for ballast water treatment
Authors: Laksono Fajar Budi , Majid Dian , Prabowo Aditya Rio 
Published: June 2022

Abstract

Background
The problem of ballast water is caused by microorganisms. The solution to solve this problem is ballast water disinfection. Until the recent day, there have not been many practical solutions. Usually, ozone, chlorine, and UV treatments were used for disinfection. However, these methods still have many weaknesses in treating ballast water.

Methods
The ferrate(vi) system proposed in this paper is liquid ferrate(vi) produced on-site using a slow-released system and combined with ultrasound. This paper investigated the optimum time to produce liquid ferrate(vi), pH, and temperature.

Results
The optimum synthesis time has been observed to be 10 min with the produced ferrate(vi) of 42,000 ppm. The optimal pH and temperature to make ballast water harmless have been observed to be the neutral pH condition at 25°C, respectively. The design of ballast water treatment using ferrate(vi) combined with ultrasound has also been proposed in this paper.

Conclusions
Ferrate(vi), as the primary material in ballast water treatment, has been successfully synthesized. The process of ballast water treatment using ferrate(vi) combined with ultrasound can be performed automatically using a time sensor and a mass sensor. With the proposed design, it can be a promising solution to solve the problems related to ballast water.
The Rural-Urban Continuum and the 2020 U. S. Presidential Election
Authors: Johnson Kenneth M. , Scala Dante J. 
Published: June 2022

AbstractThe question, “What is rural?”, has become increasingly salient to scholars of American politics over the past decade, especially after the 2016 election of Donald Trump. While social and political tensions between urban and rural residents of the United States are now widely recognized, rural cannot simply be defined as the antithesis of urban. Using survey data and voting returns from the 2020 election, we illustrate how urban-rural differences are best understood not as a dichotomy, but as a continuum. Large metropolitan core counties comprise one pole of this continuum: their residents are most likely to vote Democratic, and to express liberal attitudes on a variety of topics. At the other pole are counties far from urban areas with no towns, where conservative attitudes are widespread and Republican majorities are substantial. Between the two poles lie a continuum of counties with widely varying positions along the liberal-conservative dimension and voting records to match. We find this urban-rural continuum provides considerable analytical utility even in a multivariate spatial regression model that incorporates numerous other important demographic, economic, and social variables. Our analytical framework takes a step beyond the bipolarity that typically characterizes the discussion of urban and rural America.

Abstract
Three complexes, namely complex (1), complex (2), and complex (3), were synthesized and characterized by X-ray diffraction, thermogravimetric study, and elemental study. Complex (1) comprises discrete binuclear clusters, where two oxygen atoms of 2-chloro-5-nitrobenzoic acid bridge the two copper atoms. Complex (2) is a six-coordination structure consisting of four nitrogen atoms and two oxygen atoms in 2-chloro-5-nitrobenzoic acid and 1,10-phenanthroline to furnish a twisted octahedron. Complex (3) is a six-coordination structure consisting of four oxygen atoms and two nitrogen atoms from the 2-chloro-5-nitrobenzoic acid, methanol, and 2,2′-dipyridyl to furnish a distorted octahedral geometry. Metal complexes’ anti-tumor activity was also investigated by the MTT assay. Of the complexes tested, complex (1) could induce apoptosis in these A549 lung cancer and Caco-2 colon adenocarcinoma cells and complex (2) could induce apoptosis in Caco-2 colon adenocarcinoma cells. CCDC for complex (1) was 1543354, CCDC for complex (2) was 1546991, and CCDC for complex (3) was 1543417.

Authors: Pamplona de Sousa Gustavo César , Gomes da Silva Kelly Cristiane , Alves Júnior Clodomiro 
Published: June 2022

Abstract
Selective coatings are produced with high absorption in the ultraviolet/visible range, composed of ilmenite deposited on stainless steel substrates and aluminum substrates, using the cathodic cage plasma nitriding/deposition technique, for application in solar thermal absorbers. Ilmenite was initially characterized by means of X-ray fluorescence, X-ray diffractometry and thermal analysis. The coatings produced were optically characterized in the UV/Vis range, the microstructural evaluation of coatings was by scanning electron microscopy and data on the roughness parameters of the films produced were obtained by optical profilometry. Uniform selective surfaces with high solar absorbance (87 %) were obtained in the ilmenite samples deposited on stainless steel substrate.
Influence of water-absorbent polymer balls on the structural performance of reinforced concrete beam: An experimental investigation
Authors: Hussen Nibras Farooq , Mohammed Shatha Dheyaa 
Published: June 2022

AbstractThis research investigated the influence of water-absorbent polymer balls (WAPB) on reinforced concrete beams’ structural behavior experimentally. Four self-compacted reinforced concrete beams of identical geometric layouts 150 mm × 200 mm × 1,500 mm, reinforcement details, and compressive strengthfc′{f}_{\text{c}}^{^{\prime} }≈ 50 MPa were castellated. Each beam contained a volume percentage of WAPB that differed from the others, and the considered percentages wereVb= 0, 1, 2, and 3%. A static test under two-point loads was adopted to evaluate the structural behavior of the tested beams. The results indicated that the maximum load capacity of the tested beams was increased by 2.0, 3.0, and 7.14% for the volume percentages of 1, 2, and 3%, respectively, as compared to the reference beam (Vb= 0%). It was also observed that the impact ofVb= 3% was higher than that of the other percentages. For all the tested beams, the mode of failure was a flexural failure that is compatible with the considered preliminary design. The results showed that increasing the percentage of polymer to 3% had a significant effect on the deflection, as the deflection was directly proportioned to the percentage of WAPB.

Abstract
Nano-hydroxyapatite (nano-HA) has been widely studied as a promising biomaterial because of its potential mechanical and biological properties. In this article, different synthesis methods for nano-HA were summarized. Key factors for the synthesis of nano-HA, including reactant concentration, effects of temperature, PH, additives, aging time, and sintering, were separately investigated. The biological performances of the nano-HA depend strongly on its structures, morphology, and crystallite sizes. Nano-HA with different morphologies may cause different biological effects, such as protein adsorption, cell viability and proliferation, angiogenesis, and vascularization. Recent research progress with respect to the biological functions of the nano-HA in some specific biological applications are summarized and the future development of nano-sized hydroxyapatite is prospected.
Insights From the NANOforArt Project: Application of Calcium-Based Nanoparticle Dispersions for Improved Preservation of Parchment Documents
Authors: Bartoletti Angelica , Odlyha Marianne , Bozec Laurent 
Published: June 2022

Abstract
Following pilot testing of the effects of alkaline-based nanoparticles on modern parchment, the treatment was extended to historical parchment. This paper describes the application and impact of calcium hydroxide and calcium carbonate nanoparticles dispersed in (i) propan-2-ol and (ii) cyclohexane on a parchment book cover dated 1570. The cover showed signs of damage resulting from contact with iron gall inks and low pH values (∼4–5). Protocols for the damage assessment of collagen in parchment as developed in the IDAP project (Improved Damage Assessment of Parchment) were used to evaluate the impact of the conservation treatments on parchment. Preliminary results have shown that the application of calcium-based nanoparticles did not produce any adverse effects on the state of preservation of collagen. In addition, positive outcomes emerged: the pH was re-adjusted to a neutral value, a strengthening and consolidation effect was observed, and the nanoparticles exhibited a protective action upon artificial ageing of the treated parchment.

AbstractGerm cells are unique in engendering totipotency, yet the mechanisms underlying this capacity remain elusive. Here, we perform comprehensive and in‐depth nucleome analysis of mouse germ‐cell development in vitro, encompassing pluripotent precursors, primordial germ cells (PGCs) before and after epigenetic reprogramming, and spermatogonia/spermatogonial stem cells (SSCs). Although epigenetic reprogramming, including genome‐wide DNA de‐methylation, creates broadly open chromatin with abundant enhancer‐like signatures, the augmented chromatin insulation safeguards transcriptional fidelity. These insulatory constraints are then erased en masse for spermatogonial development. Notably, despite distinguishing epigenetic programming, including global DNA re‐methylation, the PGCs‐to‐spermatogonia/SSCs development entails further euchromatization. This accompanies substantial erasure of lamina‐associated domains, generating spermatogonia/SSCs with a minimal peripheral attachment of chromatin except for pericentromeres—an architecture conserved in primates. Accordingly, faulty nucleome maturation, including persistent insulation and improper euchromatization, leads to impaired spermatogenic potential. Given that PGCs after epigenetic reprogramming serve as oogenic progenitors as well, our findings elucidate a principle for the nucleome programming that creates gametogenic progenitors in both sexes, defining a basis for nuclear totipotency.

Published: June 2022

OBJECTIVES
Coronavirus disease 2019 (COVID-19) treatment guidelines rapidly evolved during the pandemic. The December 2020 Infectious Diseases Society of America (IDSA) guideline, endorsed by the Pediatric Infectious Diseases Society, recommended steroids for critical disease, and suggested steroids and remdesivir for severe disease. We evaluated how medications for children hospitalized with COVID-19 changed after guideline publication.

METHODS
We performed a multicenter, retrospective cohort study of children aged 30 days to &lt;18 years hospitalized with acute COVID-19 at 42 tertiary care US children’s hospitals April 2020 to December 2021. We compared medication use before and after the December 2020 IDSA guideline (pre- and postguideline) stratified by COVID-19 disease severity (mild–moderate, severe, critical) with interrupted time series.

RESULTS
Among 18 364 patients who met selection criteria, 80.3% were discharged in the postguideline period. Remdesivir and steroid use increased postguideline relative to the preguideline period, although the trend slowed. Postguideline, among patients with severe disease, 75.4% received steroids and 55.2% remdesivir, and in those with critical disease, 82.4% received steroids and 41.4% remdesivir. Compared with preguideline, enoxaparin use increased overall but decreased among patients with critical disease. Postguideline, tocilizumab use increased and hydroxychloroquine, azithromycin, anakinra, and antibiotic use decreased. Antibiotic use remained high in severe (51.7%) and critical disease (81%).

CONCLUSIONS
Although utilization of COVID-19 medications changed after December 2020 IDSA guidelines, there was a decline in uptake and incomplete adherence for children with severe and critical disease. Efforts should enhance reliable delivery of guideline-directed therapies to children hospitalized with COVID-19 and assess their effectiveness.
