Authors: Syafei Ermi Suhasti , Ihab Habudin
Published: March 2020

The tradition of early marriage is a classic social problem faced by several regions. In the past four years this tradition has declined significantly, especially in Gunung Kidul, Yogyakarta. This achievement was influenced by the existence of a creative program in the form of a program of maturation of age marriage. This article explains the process of procuring a program of maturation of age marriage in Gedangsari Subdistrict, Gunungkidul Regency. The results of the study indicate the provision of a program of maturation of age marriage to prevent the occurrence of child marriage involving various related organizations and institutions. This program is very effective in reducing the rate of child marriage in Gedangsari. This program can be interpreted as social engineering so that social changes occur in the community through the process of adaptation, efforts to achieve goals, integration and latency of systems and social structures. Social engineering through law enforcement is built on rational and legal (rational-legal) arguments.

Published: March 2020

Giving a marriage card together with marriage book for a married couple after the marriage contract is completed, as a consequence of the issuance of Peraturan Menteri Agama Nomor 19 Tahun 2018 tentang Pencatatan Perkawinan, has caused polemics among the public, especially regarding the urgency of issuing the card. In this case, some cicles consider that the issuance of marriage cards has a positive impact in facing demands in the digital era, especially in terms of efficiency, originality and data integration; on the contrary some other circles stated that the issuance of marriage card was not necessary given the existence of a marriage book so that it could potentially waste the budget, but this opinion was countered. If viewed from the aspect of its existence, the issuance of marriage cards includes maslahah mursalah because it is not all supported or rejected by the dalil syara’, but in line with syara law; in terms of the level of their needs, including maslahah hajiyah because it complements the existence of a marriage book so that it makes it easier to live life and eliminate the difficulties associated with hifdh al-nasl; in terms of its content, including maslahah ‘ammah because it relates to interests of the majority of Indonesian citezens; in terms of its content, including maslahah mah ammah because it relates to the interests of the majority of Indonesian citizens; and in terms of changes, including maslahah mutaghayirah because it allows for changes in human human needs related to proof of marital status in line with the changing era.

Madura region with diverse cultural backgrounds which become its specialty always ignores the attention of researchers to uncover, as it has become unique on most of Madura Island, especially Pamekasan at the time of engagement, a man who has been engaged in carrying out the tradition of carrying out traditions in the form of metrae and nyalene. Metrae and nyalene are usually done by the community in the last 10 months of Ramadan, together with the obligation to issue zakat fitrah for Muslims and end before the Eid Al-Fitr prayers. The submission of pertra and salenan is usually done by the parents of the male fiance, but there is a small portion of the men who are engaged to visit the residence of the female fiance with petra and salenan. Petra and salenan in the form of rice or money worth the petra and the salenan, sometimes in the form of a piece of cloth, a set of clothes or enough money to buy clothes. The tradition of metrae and nyalene is carried out, because it is driven by the desire to help each other and help reduce the burden of the female fiancee, to strengthen the bond of friendship between the two, the love that is being knitted can be bound until the time to hold a marriage contract. By submitting petra and salenan mean to imply that engagement prepared forwarded. Metrae and nyalene both form, scope and motivation of the implementer are included in the 'urf saheeh , namely, customs that apply in the midst of society and do not conflict with the Qur'an and Hadith texts, do not violate religious principles, do not contradict with reason and human mind, does not eliminate prosperity and does not bring harm even, to carry out and preserve this tradition, including carrying out religious principles in the form of help to help

MUSE Observations of NGC330 in the Small Magellanic Cloud: Helium Abundance of Bright Main-sequence Stars*
Authors: Carini R. , Biazzo K. , Brocato E. , Pulone L. , Pasquini L.
Published: March 2020

We present observations of the most bright main-sequence stars in the Small Magellanic Cloud stellar cluster NGC 330 obtained with the integral-field spectrograph, the Multi Unit Spectroscopic Explorer, at the Very Large Telescope. The use of this valuable instrument allows us to study both photometric and spectroscopic properties of stellar populations of this young star cluster. The photometric data provide us a precise color–magnitude diagram, which seems to support the presence of two stellar populations of ages of ≈18 Myr and ≈30 Myr assuming a metallicity of Z = 0.002. Thanks to the spectroscopic data, we derive a helium abundance of 10 main-sequence stars within the effective radius of R
eff = 20″ of NGC 330, thus leading to an estimation of

 = 10.93 ± 0.05(1σ). The helium elemental abundances of stars likely belonging to the two possible stellar populations do not show differences or dichotomy within the uncertainties. Thus, our results suggest that the two stellar populations of NGC 330, if they exist, share similar original He abundances. If we consider stellar rotation velocity in our analysis, a coeval (30 Myr) stellar population, experiencing different values of rotation, cannot be excluded. In this case, the mean helium abundance

obtained in our analysis is 11.00 ± 0.05 dex. We also verified that possible non-LTE (NLTE) effects cannot be identified with our analysis because of the spectral resolution and they are within our derived abundance He uncertainties. Moreover, the analysis of the He abundance as a function of the distance from the cluster center of the observed stars does not show any correlation.
An Analysis of the Statistics and Systematics of Limb Anomaly Detections in HST/STIS Transit Images of Europa
Authors: Giono Gabriel , Roth Lorenz , Ivchenko Nickolay , Saur Joachim , Retherford Kurt , Schlegel Stephan , Ackland Marcus , Strobel Darrell
Published: March 2020

Several recent studies derived the existence of plumes on Jupiter’s moon Europa. The only technique that provided multiple detections is the far-ultraviolet imaging observations of Europa in transit of Jupiter taken by the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST). In this study, we reanalyze the three HST/STIS transit images in which Sparks et al. identified limb anomalies as evidence for Europa’s plume activity. After reproducing the results of Sparks et al., we find that positive outliers are similarly present in the images as the negative outliers that were attributed to plume absorption. A physical explanation for the positive outliers is missing. We then investigate the systematic uncertainties and statistics in the images and identify two factors that are crucial when searching for anomalies around the limb. One factor is the alignment between the actual and assumed locations of Europa on the detector. A misalignment introduces distorted statistics, most strongly affecting the limb above the darker trailing hemisphere where the plumes were detected. The second factor is a discrepancy between the observation and the model used for comparison, adding uncertainty in the statistics. When accounting for these two factors, the limb minima (and maxima) are consistent with random statistical occurrence in a sample size given by the number of pixels in the analyzed limb region. The plume candidate features in the three analyzed images can be explained by purely statistical fluctuations and do not provide evidence for absorption by plumes.
The Trigger Mechanism of Recurrent Solar Active Region Jets Revealed by the Magnetic Properties of a Coronal Geyser Site
Authors: Paraschiv Alin Razvan , Donea Alina , Leka K. D.
Published: March 2020

Solar active region jets are small-scale collimated plasma eruptions that are triggered from magnetic sites embedded in sunspot penumbral regions. Multiple trigger mechanisms for recurrent jets are under debate. Vector magnetic field data from Solar Dynamics Observatory (SDO) Helioseismic and Magnetic Imager (HMI) observations are used to analyze a prolific photospheric configuration, identified in extreme ultraviolet observations as a “coronal geyser,” that triggered a set of at least 10 recurrent solar active region jets. We focus on interpreting the magnetic fields of small-scale flaring sites aiming to understand the processes that govern recurrent jet eruptions. We perform a custom reprocessing of the SDO-HMI products, including disambiguation and uncertainty estimation. We scrutinized the configuration and dynamics of the photospheric magnetic structures. The magnetic configuration is described, via the analysis of the photospheric magnetic vertical fields, to identify the process that is responsible for driving the jet eruptions. We report that the two widely debated magnetic trigger processes, namely magnetic flux cancellation and magnetic flux emergence, appear to be responsible on a case by case basis for generating each eruption in our set. We find that 4 out of 10 jets were due to flux cancellation, while the rest were clearly not and were more likely due to flux emergence.
Effects of Symmetry Energy on the Equation of State for Simulations of Core-collapse Supernovae and Neutron-star Mergers
Authors: Shen Hong , Ji Fan , Hu Jinniu , Sumiyoshi Kohsuke
Published: March 2020

We construct a new equation of state (EOS) for numerical simulations of core-collapse supernovae and neutron-star mergers based on an extended relativistic mean-field model with a small symmetry energy slope L, which is compatible with both experimental nuclear data and recent observations of neutron stars. The new EOS table (EOS4) based on the extended TM1 (TM1e) model with L = 40 MeV is designed in the same tabular form and compared with the commonly used Shen EOS (EOS2) based on the original TM1 model with

. This is convenient and useful for performing numerical simulations and examining the influences of symmetry energy and its density dependence on astrophysical phenomena. In comparison with the TM1 model used in EOS2, the TM1e model provides a similar maximum neutron-star mass but smaller radius and tidal deformability for a 1.4M
⊙ neutron star, which is more consistent with current constraints. By comparing the phase diagram and thermodynamic quantities between EOS4 and EOS2, it is found that the TM1e model predicts a relatively larger region of nonuniform matter and softer EOS for neutron-rich matter. Significant differences between EOS4 and EOS2 are observed in the case with low proton fraction, while the properties of symmetric matter remain unchanged.
Revising Natal Kick Prescriptions in Population Synthesis Simulations
Authors: Giacobbo Nicola , Mapelli Michela
Published: March 2020

Natal kicks are a matter of debate and they significantly affect the merger rate density of compact objects. Here, we present a new simple formalism for natal kicks of neutron stars (NSs) and black holes (BHs). We describe the magnitude of the kick as

, where f
H05 is a normalization factor, drawn from a Maxwellian distribution with one-dimensional rms velocity σ = 265 km s−1, m
ej is the mass of the supernova (SN) ejecta, and m
rem is the mass of the compact object. This formalism matches the proper motions of young Galactic pulsars and can naturally account for the differences between core-collapse SNe of single stars, electron-capture SNe and ultra-stripped SNe occurring in interacting binaries. Finally, we use our new kick formalism to estimate the local merger rate density of binary NSs (R
BNS), BH–NS binaries (R
BHNS), and binary BHs (R
BBH), based on the cosmic star formation rate density and metallicity evolution. In our fiducial model, we find R
BNS ∼ 600 Gpc−3 yr−1, R
BHNS ∼ 10 Gpc−3 yr−1, and R
BBH ∼ 50 Gpc−3 yr−1, fairly consistent with the numbers inferred from the LIGO–Virgo collaboration.
Mass Bias of Weak-lensing Shear-selected Galaxy Cluster Samples
Authors: Chen Kai-Feng , Oguri Masamune , Lin Yen-Ting , Miyazaki Satoshi
Published: March 2020

We estimate the Eddington bias on weak-lensing mass measurements of shear-selected galaxy cluster samples. The mass bias is expected to be significant because constructions of cluster samples from peaks in weak-lensing mass maps and measurements of cluster masses from their tangential shear profiles share the same noise. We quantify this mass bias from large sets of mock cluster samples with analytical density profiles and realistic large-scale structure noise from ray-tracing simulations. We find that, even for peaks with signal-to-noise ratio larger than 4.0 in weak-lensing mass maps constructed in a deep survey with a high source galaxy number density of 30 arcmin−2, derived weak-lensing masses for these shear-selected clusters are still biased high by ∼55% on average. Such a large bias mainly originates from upscattered low-mass objects, which is an inevitable consequence of selecting clusters with a noisy observable directly linked to the mass measurement. We also investigate the dependence of the mass bias on different physical and observational parameters, finding that the mass bias strongly correlates with cluster redshifts, true halo masses, and selection signal-to-noise thresholds, but having moderate dependence on observed weak-lensing masses and survey depths. This bias, albeit considerable, can still be modeled accurately in statistical studies of shear-selected clusters, as the intrinsic scatter around the mean bias is found to be reasonable in size. We demonstrate that such a bias can explain the deviation in X-ray properties previously found on a shear-selected cluster sample. Our result will be useful for turning large samples of shear-selected clusters available in future surveys into potential probes of cosmology and cluster astrophysics.

We introduce LATIS, the Lyα Tomography IMACS Survey, a spectroscopic survey at Magellan designed to map the z = 2.2–2.8 intergalactic medium (IGM) in three dimensions by observing the Lyα forest in the spectra of galaxies and QSOs. Within an area of 1.7 deg2, we will observe approximately half of ≳L* galaxies at z = 2.2–3.2 for typically 12 hr, providing a dense network of sightlines piercing the IGM with an average transverse separation of 2.5 h
−1 comoving Mpc (1 physical Mpc). At these scales, the opacity of the IGM is expected to be closely related to the dark matter density, and LATIS will therefore map the density field in the z ∼ 2.5 universe at ∼Mpc resolution over the largest volume to date. Ultimately, LATIS will produce approximately 3800 spectra of z = 2.2–3.2 galaxies that probe the IGM within a volume of 4 × 106
h
−3 Mpc3, large enough to contain a representative sample of structures from protoclusters to large voids. Observations are already complete over one-third of the survey area. In this paper, we describe the survey design and execution. We present the largest IGM tomographic maps at comparable resolution yet made. We show that the recovered matter overdensities are broadly consistent with cosmological expectations based on realistic mock surveys, that they correspond to galaxy overdensities, and that we can recover structures identified using other tracers. LATIS is conducted in Canada–France–Hawaii Telescope Legacy Survey fields, including COSMOS. Coupling the LATIS tomographic maps with the rich data sets collected in these fields will enable novel studies of environment-dependent galaxy evolution and the galaxy–IGM connection at cosmic noon.

The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over 75% of the sky from the Atacama Desert, Chile, at frequency bands centered near 40, 90, 150, and 220 GHz. CLASS measures the large angular scale (1° ≲ θ 

 90°) CMB polarization to constrain the tensor-to-scalar ratio at the r ∼ 0.01 level and the optical depth to last scattering to the sample variance limit. This paper presents the optical characterization of the 40 GHz telescope during its first observation era, from 2016 September to 2018 February. High signal-to-noise observations of the Moon establish the pointing and beam calibration. The telescope boresight pointing variation is <0.°023 (<1.6% of the beam’s full width at half maximum (FWHM)). We estimate beam parameters per detector and in aggregate, as in the CMB survey maps. The aggregate beam has an FWHM of 1.°579 ± 0.°001 and a solid angle of 838 ± 6 μsr, consistent with physical optics simulations. The corresponding beam window function has a sub-percent error per multipole at ℓ < 200. An extended 90° beam map reveals no significant far sidelobes. The observed Moon polarization shows that the instrument polarization angles are consistent with the optical model and that the temperature-to-polarization leakage fraction is <10−4 (95% C.L.). We find that the Moon-based results are consistent with measurements of M42, RCW 38, and Tau A from CLASS’s CMB survey data. In particular, Tau A measurements establish degree-level precision for instrument polarization angles.

In June 2019, an ecology field course of the University of Helsinki was held at Lammi Biological Station, Southern Finland. Within this course, the students familiarised themselves with field work and identification of spiders and explored the diversity of species in the area. Three sampling plots were chosen, one in grassland and two in boreal forest, to demonstrate the sampling techniques and, by applying a standardised protocol (COBRA), contribute to a global spider biodiversity project.

The collected samples contained a total of 3445 spiders, of which 1956 (57%) were adult. Only adult spiders were accounted for in the inventory due to the impossibility of identification of juveniles. A total of 115 species belonging to 17 families were identified, of which the majority (58 species, 50%) were Linyphiidae. Lycosidae and Theridiidae both had 11 species (10%) and all the other families had seven or fewer species. Linyphiidae were also dominant in terms of adult individuals captured, with 756 (39%), followed by 705 (36%) Lycosidae. Other families with more than 100 individuals were Thomisidae (196, 10%) and Tetragnathidae (102, 5%). The most abundant species were the lycosids Pardosa fulvipes (362, 19%) and Pardosa riparia (290, 15%) and the linyphiid Neriene peltata (123, 6%).

Émergence des identifications sexuées : un fil rouge créatif dans la psychothérapie avec les enfants autistes
Authors: Mazéas Dominique
Published: March 2020

Confronté à des éprouvés d’étrangeté dans la rencontre avec le jeune enfant autiste et à la fragilité de constitution de son image du corps, le thérapeute peut perdre de vue la question de la construction de ses identifications sexuées. Il risque alors de se priver d’une ressource créative dans le transfert avec l’enfant et sa famille. À partir d’études de cas d’enfants reçus en psychothérapie au long cours, cet article propose d’explorer quelques ressorts thérapeutiques offerts par l’attention que porte le thérapeute aux voies de construction parfois insolites des identifications sexuées dans l’autisme. Cette attention soutient la qualification des recherches sensorielles des enfants et facilite la relance des identifications réciproques entre l’enfant et son entourage. Elle favorise ainsi l’élaboration des douleurs de transmission dans le lien parents-enfant.
Dans l’intervalle entre l’œuvre et l’auditeur : l’interprète de chansons
Authors: Hureau Serge , Hussenet Olivier
Published: March 2020

Umberto Eco démarre son enquête sur l’interprétation des œuvres littéraires en distinguant trois types d’intentions : intentio auctoris , intentio operis et intentio lectoris ( Les limites de l’interprétation , Paris, Grasset, 1990, p. 29-32). Pour aborder la question de l’interprétation de chansons, nous choisissons de distinguer le travail d’interprétation de l’auteur ou du compositeur de la chanson (ou de la chanson elle-même) de ceux de l’artiste-interprète et du public. S’appuyant sur notre expérience d’artistes de scène et de formateurs d’artistes, et quoique non spécialistes de la théorie psychanalytique, nous formulons l’hypothèse que l’un des rôles majeurs de l’artiste-interprète consiste à instaurer une distance productrice de sens entre l’auditeur (ou le fan) et la chanson (fétiche porté par une idole).
Le jeu de l’interprétation et de la compréhension chez Freud et chez Lacan
Authors: Cléro Jean-Pierre
Published: March 2020

Si l’on s’intéresse au couple des mots « comprendre » et « interpréter », on s’aperçoit que la compréhension est beaucoup moins problématisée par Freud que ne l’est l’interprétation, alors que Lacan rééquilibre le doublet en interrogeant la compréhension presque autant que l’interprétation. Sur la compréhension, il défend une thèse : l’analyste comprend toujours trop, puisque ce qu’il comprend est précisément ce que ne comprend pas l’analysant ; et ce qui est à comprendre est très exactement ce qui fait que ce dernier ne comprend pas. Sur l’interprétation, presque toujours comprise en rapport dialectique avec la compréhension, la thèse est moins forte, mais l’originalité est plus grande, puisqu’il fait un usage, inattendu et pour ainsi dire discret, de la théorie benthamienne des fictions que lui a indiquée son ami R. Jakobson. C’est donc à une logique des fictions qu’il soumet l’interprétation, avec le jeu qu’il emprunte à Bentham entre le réel, le symbolique et l’imaginaire ; et avec sa possibilité de renversement de réel en symbolique et de symbolique en réel, qui lui permet de poser ce qu’on appelle, en logique et en mathématique, les « problèmes inverses » et de les introduire en psychanalyse. Il ne s’agit évidemment pas de soutenir la thèse excessive que l’usage de la théorie des fictions dans son système RSI soit la seule dimension de l’interprétation.

Published: March 2020

Instrumentation subject has a major and vital role in the industrial field. The concepts of sensors, actuators, signal interface, and conditioning, programming the microprocessor and microcontroller are the most important requisites to comprehend and contribute to the real-world application. The application of these concepts is PLC and Robotics course where the students can apply and practical experience the output. To design a project and to implement we need multidisciplinary concepts and sequence of steps viz., defining an idea, requirements and the fabricating parts to bring out a visual structure in order to perform an intended function. To inculcate this culture it’s much more important to follow and implement the standard and well-known methodology called Bloom’s taxonomy in the classroom environment for a better outcome of the course. Current leading technology PLC and Robotics course, (which require prerequisite knowledge of courses like Instrumentation, Microprocessors, Mechatronics) are very well connected for applying the gained concepts to continue the stream of the learning process. The paper presents how to bring better learning Outcomes and also create interest in the course PLC and Robotics by implementing Bloom’s taxonomy by conducting activities in the classroom.

The use of dilatometry in determining the manner of selecting ossuary vases: the case of Lugdunum during the Early Roman Empire
Authors: Thirion-Merle Valérie , Batigne Vallet Cécile , Bonnet Christine , Bernet Alain
Published: March 2020

A recent synthesis of Lyon/Lugdunum’s ossuary ceramic ware showed that, typologically, the ceramics used to collect the residues of burnt bone were the same as those used in the city’s kitchens (Bonnet et al., 2016). The forms are indeed strictly the same. Nevertheless, some ossuary pots from the only two funerary areas known from the Augusto-Tiberian period show particular traces totally unknown on domestic ceramics, such as slits, crumbling peeled surfaces, manufacturing flaws and other characteristics suggesting insufficient firing temperature. The authors propose the hypothesis of an opportunistic use of these pots unsuitable for culinary use. In order to check if these pots were truly underfired, we have measured about thirty ossuary ceramic ware apparent firing temperatures with a dilatometer. The elemental compositions were also determined by X-Ray fluorescence spectrometry to identify the provenance of the pots. This paper will present the results of this study and offer some interpretations of the transfer of these objects from a domestic to a funerary context.

Brick samples from different archaeological sites represent mostly houses in Brussels (Belgium) built between the end of the Middle ages (end of 13th-beginning 14th centuries) and the end of the Modern Period (18th century). The study gives a mineralogical–petrographical–chemical characterization of the brick samples made in the Brussels-Region and sources the raw silty material, the moulding sand and the lime-mortar. Optical microscopy, X-ray powder diffractometry, Laser Ablation Inductively Coupled Plasma Mass Spectrometry, magnetic susceptibility and scanning electron microscopic with an energy dispersive X-ray attachment were applied both to fired clay bricks and regional clayey materials. Bricks were moulded with a silica rich, non-calcareous loam gathered locally in the alluvial plain of the Senne valley. Material from gleysols and fluvisols were mined separately to shape two types of bricks. A strong chemical resemblance with the thick loessic deposits of the Belgian plateaus results from erosion and river transport and sedimentation in the wide alluvial plain of Brussels. Petrography and geochemistry show minor participation of marine Lower Palaeozoic, Cretaceous and Tertiary rocks from the alimentation area of the Senne. Although clayey tertiary layers outcrop in the Brussels Region and are cut by the numerous tributaries of the Senne valley, they were never exploited for brick making in the Brussels Capital Region. Mineralogical composition and petrography suggest the absence of mixing with river sand or local marine tertiary sands. Local sediments extracted in the valley sides as Eocene fossiliferous fine sand were used as moulding sand.

Authors: Kargiglioğlu Şaban , Erkol Bayram Gül
Published: March 2020

All the changes are based on the ability to make the most of the human resources they possess, rather than the material elements, in order to survive in an environment of increasing creativity and competition. According to the businesspeople, physical, mental, and emotional dimensions are different from each other. Although it is difficult to manage the human resources that have these differences, the capacity and success level of the enterprise will increase when it is managed effectively. Management of differences in tourism enterprises, in addition to respecting and not discriminating between individuals and groups in accommodation, food and beverage, recreation establishments, and travel agencies, are evaluated and utilized for individual and organizational purposes. The aim of managing differences in the tourism sector is to create an appropriate working environment for all tourism staff, to increase the potential advantage of differences and to reduce their potential drawbacks.

Published: March 2020

Businesses merge with other businesses, acquire other businesses, and restructuring using various methods to reduce costs. One of these methods is downsizing. Many businesses that try to survive, especially in times of crisis, need organizational downsizing strategies. Organizational downsizing means reducing the number of employees and continuing with fewer employees in total. Early retirement, direct dismissal, freezing of hiring practices can be used in this context. Tourism is a sensitive sector due to the nature of the sector and sometimes there may be economically and financially problematic periods. Tourism businesses can achieve positive results in these periods with downsizing strategies. In this chapter, history of organizational downsizing, stages of organizational downsizing, and organizational downsizing strategies are explained by the literature.

This study reports on a case study of TQM adoption in searching for answers of why and how organizations adopt such approaches to gain competitive advantages within a Bangladeshi beverage company. It focuses organizational approaches to adopt TQM as a strategic option and the subsequent changes in organizational set-up. Moreover, using the resource-based theory, this study explores what TQM components help achieving competitive advantage. Findings reveal that due to the change in customer requirements in respect to tastes and quality; and increased price pressure led the case organization to adopt TQM. The result shows that the case organization has brought a series of changes in adopting TQM including appointing a consultant; encouraging a culture of continuous learning; developing a mechanism of communicating information; involving top management along with the employees in the improvement process; and emphasizing the use of teams. Following the resource-based view, findings show that the adoption of TQM helped the case organization in identifying its capabilities that facilitated the achievement of competitive advantage. The findings may help other organizations to learn lesson from the case organization through the identification of tacit resources that are generated by a TQM initiative.
Utilization of Modified Coal Fly Ash (CFA) as a Catalyst for Production of Biodiesel from Coconut Oil: Part 1 - Characteristics of the Catalyst
Authors: Hidayat Arif , Chafidz Achmad , Sutrisno Bachrun
Published: March 2020

The current research studied about the utilization of modified coal fly ash (CFA) as catalyst for biodiesel production from coconut oil. Coal Fly ash (CFA) is a solid waste that is abundantly available in the coal-based power plant. Coal Fly Ash is a type of material that has high content of oxide minerals, e.g. silicates and silicate alumina. With proper physical/chemical treatment, the coal fly ash can be converted into a heterogeneous catalyst. In this work, the coal fly ash was modified with HCl and Ca(NO3)2·4H2O and used as catalyst for biodiesel production from coconut oil. This paper will focus only on the characteristics of the prepared modified CFA-based catalyst. The modified CFA-based catalyst was characterized for its crystallinity using X-Ray Diffraction (XRD), determined its surface area and pore size distribution using Surface Area Analyzer, and its functional groups by Fourier Transform – Infra Red (FT-IR). The specific surface area of the catalyst (modified CFA) decreased from 28.08 m2/g to 17.54 m2/g after impregnation process of calcium oxide in the raw coal fly ash. This decrease was also accompanied by a decrease in the average pore network from 32.59 Å to 20.31 Å. Additionally, based on the XRD pattern shown, the raw CFA is composed of mostly quartz (SiO2) and mullite (3Al2O3.2SiO2) minerals, and a small portion of hematite.
