Abstract
The emergence and discussion of the reasonable choice of methodological bases for the creation and subsequent application of electronic training courses within the framework of a separate study is not accidental. Analysis of the theory and practice of the use of information technologies in education showed that, along with the discussion of informatization of education, including adult education (androgogy), the use of computer-based training programs to improve the quality of teaching in various disciplines, studies of pedagogical capabilities of electronic training courses, principles of development and technology for creating electronic educational materials remain insufficiently studied. Properly grounded methodological and technological components of the process of creating such resources will ensure high quality of the final product, as well as reduction of time and financial costs. The article presents a generalized description of the basic models and methodologies for the development of electronic educational materials, namely: ADDIE (Analysis, Design, Development, Implementation, Evaluation); SAM (Successive Approximation Model); SMART (Specific, Measurable, Attainable, Relevant, Time-bound); ALD (Agile Learning Design). The authors pay special attention to the ALD (Agile Learning Design) model, describing its basic principles. The structural analysis of ALD with the help of the IDEF0 functional model allowed showing the logical interconnection of all the stages of creating an e-learning course, to demonstrate its iterative nature. The study also addresses the issue of the reasonable choice of tools for developing e-learning courses. The choice was made on the basis of T. Saati’s method of analyzing hierarchies. The selected alternatives were Adobe Captivate, Articulate Storyline and iSpringSuite as software solutions used for the professional development of e-learning materials. The choice was made on the basis of such criteria as maintenance, implementation, functionality, price, experience of usage. As a result of the testing with the MPRIORITY decision-making system, the Articulate Storyline software platform was selected as the tool for the implementation of the subsequent e-learning course project. This software product has significant functionality if compared to the other alternatives: low cost and availability of development. Further work on the creation of an e-course is sure to be carried out with its use.

Abstract
Efficient use of production capacity is an important complex of engineering tasks. Faced with the need to modernize production in the face of high competition and changing customer needs, company owners are forced to test new engineering solutions. Maximizing the existing production capacity plays a fundamental role in maintaining competitiveness and improving the efficiency of resource use in the production of electronic equipment. Electronic equipment manufacturing uses a make-to-order strategy and has a large number of variants of the product in a very small batch. But it is a problem of implementing the standard solution for efficient use of production capacities. Using simulation methods allows one to make informed decisions on using planning and scheduling in small-batch make-to-order production. We describe the process of developing a simulation model of the assembly shop of electronic production using Tecnomatix Plant Simulation software. The focus is on the search for the optimal capacity utilization of the workshop. The created model allows getting detailed statistics about various aspects of functioning of the workshop, depending on the input data.

Statistics of boundary encounters by a particle diffusing outside a compact planar domain
Authors: Grebenkov Denis S 
Published: November 2020

Abstract
We consider a particle diffusing outside a compact planar set and investigate its boundary local time ℓ

t
, i.e., the rescaled number of encounters between the particle and the boundary up to time t. In the case of a disk, this is also the (rescaled) number of encounters of two diffusing circular particles in the plane. For that case, we derive explicit integral representations for the probability density of the boundary local time ℓ

t
and for the probability density of the first-crossing time of a given threshold by ℓ

t
. The latter density is shown to exhibit a very slow long-time decay due to extremely long diffusive excursions between encounters. We briefly discuss some practical consequences of this behavior for applications in chemical physics and biology.
Irradiated foxtail millet (Setaria italica (L.) P.Beauv): agronomic and physiological performances under low light intensity
Authors: Juhaeti T 
Published: November 2020

Abstract
The research was carried out to study the agronomic and physiological performances of gamma rays Irradiated Foxtail Millet (IFM) under low light intensity as an effort to obtain a shade-tolerant mutant. The experiment was performed in a Randomized Complete Block Design (RCBD) with two factors. The first factor was shading intensities, whereas the second factor was foxtail millet mutants resulting from gamma rays irradiation. The observation was performed on agronomic and physiological parameters, including plant growth, chlorophyll content (CC), photosynthesis rate (PR), and panicle production (PP). The result of this study showed that low light intensity decreased CC and PR values. The statistical analysis showed that CC value in 50% shading (33.02SPAD) was significantly different, with 0% shading (47.56 SPAD). Accordingly to this result, the PR value at 50% shading (7.112μmolm−2s−1) presented a significant difference as compared to 0% shading (19.379μmolm−2s−1). Observations on the plant height of GM 75.16 showed no significant difference with the control plants. Similarly, the result of PP on GM75.16 (17.03g) was not significantly different as compared to the control (16.24 g) and GM75.14 (14.10g). Therefore, GM 75.16was identified as a shade-tolerant mutant due to its ability to sustain the growth and development under low light intensity.

Abstract
Prohibition of several fishing gears has been started since 2015 by issuing MMAF Ministry regulation no. 2 of 2015. The regulation prohibits several fishing gears; one of them is seine nets. MMAF Ministry regulation no. 71 of 2016 details the size of seine nets, including purse seine, which are not allowed. Fishers still believe that fishing using the purse seine with a large fleet gives more production than the hand line fishing gear with a small fleet. The purpose of this study is to see whether the hand line fishing gear has smaller production or productivity per GT than others. The data used for this study were obtained from the Letters of Evidence Report for Fishing Ship Arrival (STBLK) and from National Fishing Ports (PPN) Kwandang in the North Gorontalo Regency from March to November 2018 to be analyzed. The results show that hand line fishing gear with small fleet gets average productivity for about 9.195 Kg/GT/year compared to large vessels with purse seine fishing gear, which gets average productivity for about 1.985 Kg/GT/year.

Abstract
Buni fruit (Antidesma bunius) is a local seasonal sour fruit in Indonesia and commonly used as street foods such as rujak buni. In this study, we formulated cider drink from ripe buni fruits and determined its efficacy for cosmeceutical potency via antioxidant and collagenase inhibitory activities. Buni ciders were fermented with both single and combine cultures of Acetobacter xylinum and Saccharomyces cereviseae. Ciders were further identified by gas chromatography-mass spectrometry (GC/MS) and tested for its antioxidant activity by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical inhibitory assay, collagenase inhibitory assay, alcohol content by Conway method, total soluble phenolic content, and sensory analysis. Buni cider had a pH of about 3.0 and alcohol content up to 3.6%. Compound profiling showed that buni ciders contained flavonoids, alkaloids, and organic acids. The antioxidant activity of buni ciders was reached in the range of 73.11-78.12 %, and the total phenolic content in ciders was 7.34-22.55 mg gallic acid/mL. Buni cider fermented from single A. xylinum had a potential inhibitory effect against collagenase. Sensory profiling showed that most panelists preferred to drink buni cider fermented from single A. xylinum rather than that of other buni ciders and juice. These data indicate that ripe buni cider fermented from single A. xylinum had potential antioxidant and collagenase inhibitory effects. Besides, it could be applied for cosmeceutical application for the management of skin aging.

Abstract
Red calliandra (Calliandra calothyrsus) is an essential economic plant and used as a renewable energy source. Seed-borne fungi can be beneficial or detrimental. One of the beneficial roles of fungi is as an antagonistic agent. Red calliandra seed is commonly infected by pathogenic fungi such as Fusarium sp., Aspergillus sp., and Rhizopus sp. The purpose of this research was to identify the fungi in red calliandra seeds, which are potential as an antagonistic agent, and to study their ability to inhibit the growth of pathogenic Fusarium sp., Aspergillus sp. and Rhizopus sp. The seeds obtained are from Sukabumi, West Java, Indonesia. Fungi were isolated by soaking the seeds with 1% NaOCl for three minutes then washed with sterile aquadest. It was repeated three times. Furthermore, the seeds were sown on moist paper media and incubated until a fungus colony emerged, which is expected to be a potential antagonistic agent. The result showed that there was one isolate of fungi that was potential as an antagonistic agent; it was Talaromyces sp. It indicates that the antagonistic agent can be isolated from seeds. The inhibition percentages of Talaromyces sp. against Aspergillus sp., Fusarium sp., and Rhizopus sp. at seven days old were 67.92%, 59.4%, 8.89%, respectively. Talaromyces sp. can inhibit the growth of Fusarium sp. Rhizopus sp. and Aspergillus sp. in overgrowth at 14 days old. The antagonistic mechanism of Talaromyces sp. to Aspergillus sp., Fusarium sp. and Rhizopus sp. is microparasitism and competition. Talaromyces sp. isolated from red calliandra seeds were potential as antagonistic agents.

Abstract
Red fruit (Pandanus conoideus Lam.) is a plant native to Papua, Indonesia. The extracted oil of red fruit has been known to possess potential medical properties, including anti-inflammatory, anti-tumor, and anti-diabetic. The natural antioxidant content such as carotenoids, α-tocopherol, and unsaturated fatty acids are considered to contribute to its bioactivity. In this study, five clonehjnms of red fruit, namely Maler, Bergum, Wesi, Uaghelu, and Kenen, from different regions in Papua, were collected. Carotenoid content of the red fruit oil of the five clones, in particular β-carotene and β-cyptoxanthin, was determined by using HPLC analysis. The β-carotene content ranged from 193.9 to 1003.8 μg/ml, while β-cyptoxanthin content ranged from 3.3 to 48.9 μg/ml. Bergum oil has the highest content of both β-carotene and β-cyptoxanthin, thus it is suggested for cultivation.
Dissolved organic carbon and physicochemical variables of peat water in tropical peat swamp forests
Authors: Sundari S 
Published: November 2020

Abstract
Degradation of peatlands in Indonesia has been caused by fires, drainage, and deforestation of peat swamp forests. Fires release carbon dioxide (CO2) intensively but occasionally, whereas drainage enhances CO2 emission from the soil and dissolves organic carbon (DOC) leaching through peat water flow. DOC was affected not only by peat degradation but also by the physicochemical variables of peat water. A study on DOC and physicochemical variables of peat water to investigate the effects of drainage and fires has been conducted in three tropical peat swamp forests of Central Kalimantan. They were a relatively intact peat swamp forest with little drainage (UF), a drained peat swamp forest (DF), and a drained, burnt peat swamp forest (DB). The DOC concentration was analyzed using a total organic carbon (TOC) analyzer, while physicochemical variables, including electrical conductivity (EC), pH, and inorganic nitrogen were measured using EC meter, pH meter, and ion analyzer, respectively. Research results showed that the highest DOC concentration was measured in DF, whereas the lowest DOC concentration was in DB. DOC was resulted from peat decomposition due to low pH, low C/N, and high EC conditions. These results indicate that DOC leaching through peat water flow may occur by drainage rather than fires.

Abstract
Local wisdom is essential in the conservation of local rice. The utilization of local rice varieties has been carried out in the specific groups of people for centuries under local culture rules. Kasepuhan Cisungsang is one of the local cultures in Banten Kidul populated by indigenous people who still maintain local wisdom in rice cultivation. The research objective is to observe the role of Cisungsang indigenous culture in preserving local rice germplasm. The study was conducted in Kasepuhan Cisungsang, Cibeber District, Lebak Regency, Banten Province. The data used were primary and secondary data, with survey and desk study. The results showed that the law of Cisungsang culture applied not only to people and community life but also to agriculture, especially for rice cultivation. Rice, manifested as The Goddess “Dewi Sri,” has a noble position for indigenous people as it must be properly nurtured and nourished to provide optimal harvest. There were 30 varieties of local rice varieties grown in Kasepuhan Cisungsang and its surrounding areas. Still, only ten varieties were planted by the community, namely: Marileun, Terong Papak, Cireh Gudang, Kapundung, Tampay Beureum, Srikuning, Tampey Bodas, Nemol, Gadog, Angsana. The ten varieties were by the farmer preferences and adaptive strength in the local agroecosystem.
Hypercolorimetric multispectral Imaging and Pulse Compression thermography as innovative combined techniques for painting investigation: the case of a detached wall painting by Pastura

Published: November 2020

AbstractThis contribution focuses the attention on an innovative approach in diagnostics of paintings, based on the combine use of two imaging techniques named Hypecolorimetric Multispectral Imaging (HMI) and Pulse Compression Thermography (PuCT) applied to a 15thcentury wall painting, attributed to the Italian artist Antonio del Massaro, also known as Pastura. HMI technique is based on the simultaneous exploitation of the electromagnetic spectrum from the ultraviolet to the near infrared region. The acquisition, made under a standard metric, allows for characterizing the investigated surfaces in a more detailed way than the standard colorimetry. The system transforms any spectra in the range 300-1000nm into sevenfold hypecolorimetric coordinates. HMI guarantees very high radiometric (better than 95%) and colorimetric precision (better than ΔE = 2). PuCT is a thermography technique based on the use of coded modulated heating stimuli in combination with the pulse-compression technique. A PuCT scheme, based on coded LED excitation capable of optimizing the estimation of the impulse responses compared to the state-of-the-art PuCT literature has also been proposed. The combined use of HMI and PuCT recently revealed its potentiality in the investigation of important panel paintings by highlighting hidden details, mapping the conservation status, characterizing painting materials, etc. in a completely non-invasive way. Their combined capabilities are here tested on a wall painting representing the Madonna with the Child and the Saints Jerome and Francis, which was investigated during the restoration in the Laboratory in order to supply information about the materials and techniques.

Abstract
The present paper deals with the technic using the terrestrial laser scanning survey (TLS) in the restoration and conservation of the shared built cultural heritage in Algeria. The cross-section method, that was the skeleton of our surveys, is applied by using directly 3D meshing models.
The project described in this article was motivated by the need to document some of key buildings, that looks very venerable, in the city of Setif in Algeria: The Mosque of El Attik minaret, the mausoleum of Scipion, and the statute of the fountain of Fouara.
This statue which is made of marble was realized by Francis de St Vidal in 1899 that represents a nymph which is a part of the fountain, publicly displayed in the center of the city’s main plaza. On 18 December 2018, a man has deteriorated the statute. Following the day of the incident, our team has been called to use a previous scanner laser survey of the nymph that was stored in our cultural heritage monument database in order to help the restoration of the missing part of the nymph (the face and the breast). As a matter of fact, the original laser scanning survey provided a helpful and accurate details to support the restoration of the nymph.
If the experience of Ain fouara show all the interest of this technology not only in the digital archiving of 3D models generated; the digitization of The Mosque of El Attik minaret and the mausoleum of Scipion highlights the effective use of 3D meshing models obtained, in the study of the mechanical behaviours. This preventive approach is useful in other studies of shared cultural built heritage.

Published: November 2020

Abstract
Imaging Spectroscopic techniques, also known as hyperspectral imaging, have been utilized in museums and conservation laboratories for documentation purposes and in support of restoration treatments on different types of artworks and archaeological objects. For more than a decade, several studies and research projects have been devoted to customize imaging spectroscopic instrumentation and methodologies to the specific needs of art conservation and applications in the museum context. Other issues arise such as the need to develop new image processing software, including the mosaicking of image-cubes, new pigment identification and mapping methods, visualization, and archiving of the results. The present communication reports the data obtained on two canvas paintings made by Picasso in 1917, presently in the permanent collection of the Museu Picasso in Barcelona. The hyperspectral data have been used to document his artistic technique and to define the chemical composition of the palette. In addition, these data supported the surface observations of the morphology and crack patterns of the paint layers in order to get a better understanding of the damage found. This study was carried out in the framework of an inter-institutional research project aimed to gain an insight into the failure mechanisms of modern and contemporary paintings.

Abstract
The graphic vandalism is considered one of the most important topics in the field of conservation of cultural heritage. The most widespread means used for the acts of vandalism are the felt-tip pens and the aerosol paints. These tools irreversibly damage the stone substrates, changing their appearance and conservation state. The aim of this article is to compare and characterize four different cleaning approaches in terms of their efficacy and invasiveness in the removal of the specific brand spray used as dirtying material.
