Integration of complete elemental mass-balanced stoichiometry and aqueous-phase chemistry for bioprocess modelling of liquid and solid waste treatment systems − Part 3: Measuring the organics composition
Authors: GA Ekama  , CJ Brouckaert
Published: January 2022

Bioprocesses transform the components of the material entering single or multiple reactor systems from one kind to another without a change in total material exiting the system(s) in the solid, aqueous or gas phases.  Provided that the correct measurements are made that can quantify the material content of the bioprocess products (outputs), the material content of the bioprocess reactants (inputs) can be determined from the bioprocess products via stoichiometry. Based on this principle of mass conservation, the augmented biomethane (AugBMP) and biosulphide (AugBSP) potential test procedures are proposed, which change the BMP from a stand-alone test to a bio-reactor on which a range of additional tests are made to determine the composition of biodegradable organics. The AugBSP, which is based on biological sulphate reduction, can replace the inaccurate gas measurements in the BMP with the more accurate aqueous sulphate and sulphide measurements. The suitability of these two procedures is evaluated from a theoretical and modelling perspective. The analytical tests required to determine the composition of influent organics, expressed as CxHyOzNaPbSc, are identified. Examples of the calculation procedure from the test results are given. It is concluded that the augmented BMP (AugBMP) and BSP (AugBSP) test procedures, supplemented by anaerobic digestion dynamic modelling, are as accurate as the analytical measurements for determining the composition of biodegradable organics, and also allow the hydrolysis rate of the biodegradable organics and the unbiodegradable fraction of the organics to be determined. Knowing these characteristics of organics fed to anaerobic digesters is important to predict the anaerobic digester performance and stability.
Integration of complete elemental mass-balanced stoichiometry and aqueous phase chemistry for bioprocess modelling of liquid and solid waste treatment systems – Part 4: Aligning the modelled and measured aqueous phases
Authors: GA Ekama  , CJ Brouckaert  , BM Brouckaert
Published: January 2022

Completely mass-balanced biological, physical and chemical process stoichiometry ensures that the CHONPS material and charge content entering and exiting bioprocess system models is conserved, which is a requirement for pH prediction in integrated physical, chemical and biological process models. Bioprocesses transform the material content from reactants to products, exchanging material between the aqueous, gaseous and solid phases, which cause pH changes in the aqueous phase. By measuring the material content of the aqueous phase, the progress of bioprocesses can be monitored. Alkalinity is an important aqueous-phase property that can be used to track aqueous-phase changes caused by physical, chemical and biological processes. Alkalinity is a stoichiometry property of the components in solution (i.e., a linear function of the amounts present). Its uptake from, and release to, the aqueous phase can both be modelled with bioprocess stoichiometry, and measured in physical bioprocess systems, and so aid in linking the modelled and measured aqueous-phase compositions. Changes in the concentrations of components containing the elements C, H, O, N, P and S result in changes in six weak acid/bases systems in the aqueous phase, all of which affect the total alkalinity. These are: inorganic carbon (IC), ortho-phosphate (OP), free and saline ammonia (FSA), volatile fatty acids (VFA), free and saline sulphide (FSS) and the water itself. Characterization of the aqueous phase to quantify the material content of the aqueous phase containing these six weak acid/base systems using the 5-point titration method is described. While several alkalinity titration based methods are available for anaerobic digestion bioprocess monitoring, only the 5-point titration is sufficiently accurate for aqueous-phase characterization to quantify the aqueous-material content for pH prediction in bioprocess models.

Authors: Mohsen Dastorani  , Mohammad Albaji  , Saeed Boroomand Nasab
Published: January 2022

To compare the effect of magnetic drip irrigation and conventional irrigation with different salinity levels on water productivity and yield of sunflower (Helianthus annuus L.), a factorial experiment was conducted using a completely randomized design with 6 treatments and 3 replicates at the Research Station of the Faculty of Water Sciences Engineering, Shahid Chamran University of Ahvaz, Iran. The experiment was executed over the crop year 2018–19. The treatment variables consisted of 2 types of water (magnetically treated and non-magnetically treated) and 3 salinity levels (Karun River water (S1), 4 dS/m (S2), and 6 dS/m (S3)). The use of magnetically treated irrigation water increased the biomass water use efficiency, and the weight of 100 seeds by 13.9%, and 5.48%, respectively. With the conventional irrigation method, increased salinity reduced the seed yield. The highest seed yield and irrigation water productivity were observed at 4 459 kg/ha and 0.73 kg/m3 for grain yield at a water salinity level of S1 (the control treatment). The application of water with salinity of 4 dS/m and 6 dS/m (S2 and S3) caused a reduction in seed yield by 9.3 and 21.8%, respectively, in comparison to that of the control treatment. Moreover, irrigation water productivity for the biomass yield decreased by 14.57 and 29.23%, respectively. Based on the results of this study, the use of magnetically treated water can reduce the effects of salinity stress under conditions of salt stress. Therefore, magnetically treated water can increase the yield and productivity of irrigation water.
Comprendre l’inclusion scolaire en France.
Authors: POPESCU Cristina
Published: January 2022

Cet article interroge les notions de « citoyenneté » et de « diversité » sous l’angle des discours officiels et des pratiques de l’« inclusion scolaire » pour les élèves en situation de handicap en France. Pour cela, nous nous basons sur une analyse de textes législatifs en lien avec l’École inclusive, en vigueur en 2016, et une enquête ethnographique en milieu scolaire ordinaire et médico-social. L’article montre que l’introduction d’un nouveau projet politique de la diversité apporte des bouleversements dans les pratiques scolaires et éducatives traditionnelles, ressentis notamment dans les interactions quotidiennes des acteurs concernés. Une réinvention de l’institution scolaire apparaît nécessaire afin de combler l’écart entre une citoyenneté de droit et une citoyenneté active. Elle implique la mise à jour des routines d’apprentissage ou d’enseignement, et l’encouragement de partenariats entre des professionnels ayant montré des logiques d’action plutôt indépendantes par le passé : les enseignants et les professionnels du secteur médico-social.

Microwave Processing of Food and Biological Materials
Authors: Makiso Urugo Markos , Admassu Emire Shimelis , Tuba Tringo Tadele
Published: January 2022

Microwave processing is one of the novel food processing technologies that
use electromagnetic radiation in the wavelength and frequency between 1 mm
to 1 m and 300 MHz to 300 GHz, respectively. In this review, principles and
various applications of microwave technology for food processing are
addressed. A systematic literature search was conducted by using, Google
Scholar and, Web of Science, Open access theses and dissertations on the
principles and application of microwave processing of food were summarized.
Additionally, references of each selected publication were examined to get
more relevant articles. In microwave processing, the food material absorbs
microwave energy directly, and internally, and converts it to heat. The
technology is applicable for different unit operations in food industries such as
cooking, heating, drying, pasteurization, sterilization, thawing, tempering,
baking, blanching, and the extraction of important food biomaterials.
Microwave processing is highly advantageous over conventional food
processing techniques, in terms of retaining the nutritional content of the food
and reducing processing time. Consequently, the breakthrough of the
technology in food processing industry has been predicted before. However,
the potential of microwave technology is not widely exhausted in Africa. It is
associated with a lack of awareness, a priority setting on the application of
emerging technologies for safe and high quality value added products;
moreover, its high initial investment and operational power cost may become
a bottleneck for food processing companies in Africa. Therefore, food
innovation centres in Africa should drive high performance standards from
technology adoption to improve the application of microwave technology in
food industries.

Published: January 2022

Portland Pozzolana Cement (PPC) is prepared by adding Pozzolanic materials to ordinary Portland Cement. The artificial pozzolana materials used in the manufacturing of PPC such as fly ash, silica fume, rice husk, blast furnace slag, are actually industrial waste, which is produced in large amounts. These artificial pozzolana materials when used in concrete can reduce consumption of natural resources, diminish the effect of pollutants in the environment and it is economical and reliable. The main objective of this paper is to focus on the properties and applications of Portland Pozzolana Cement and make effective use of different industrial by-products in the manufacturing of cement. We found that both PPC and ordinary portland cement (OPC) are commonly used types of cement in construction. Nowadays, PPC is used as a substitute for ordinary Portland cement (OPC cement). Since PPC contains pozzolanic materials, it helps to enhance the strength of concrete. The quantity of PPC required in making the concrete is less when compared to OPC. PPC is a green material that contributes towards sustainable development.

Authors: Fatimah Siti , Ragadhita Risti , Husaeni Dwi Fitria Al , Nandiyanto Asep Bayu Dani
Published: January 2022

X-Ray Diffraction (XRD) has been developed to analyze a crystal structure in the material. XRD is then improved for determining and identifying the presence of a compound, crystallinity, and crystal properties. XRD works by observing the ray refraction pattern as a result of the beam being refracted by a material that has an atomic arrangement in its crystal lattice. Until now, there is less information regarding detailed information on how to read the XRD spectrum and peak. This study aims to demonstrate how to calculate and interpret the crystallite size based on the XRD spectra. The step-by-step method in the calculation based on the XRD data is presented, which can help especially students and first-time users in understanding XRD results. This study is prospective to be used as standard information on how to read and interpret XRD spectra.

Published: January 2022

This research aimed to sought solutions to the growing problems of rice black bugs (Scotinophara coarctata) damaging the rice crops of farmers. This study used an experimental method to determine which solution is effective against rice black bugs. Bignay (Antidesma bunius) leaves were collected, cut, soaked in water, crushed using a mortar and pestle, and extracted using a thin cloth. The extracts of the leaves were then placed in 4 different concentrations in bottles. 6 bugs were soaked in each solution, respectively, but with different periods (3, 5, and 10 min). We found that the extract is lethal towards black bugs since it has anti-bacterial activity, even though it damaged the rice crops. Bignay fruit was intended to be utilized as another variable, but due to the weather, fruits were not yet visible in the Bignay tree. We concluded that the thickness of the solution served as the main reason why the rice black bugs died. The result of this study can be utilized to address the rising problems caused by rice black bugs.

Authors: Pingak Charline Tiara Rehuellah , Octaviani Maria Anggi , Yuenan Given Chris , Triawan Farid
Published: January 2022

The number of COVID-19 corpses is highly increased since 2020. This situation tends to risk the health workers directly interacting with COVID-19 victims during the burial process. In Indonesia, the conventional method of burial process requires four to eight health workers. Thus, minimizing the number of involved health workers is needed. This paper aims to propose a bed-stretcher that assists the burial process of the COVID-19 corpses efficiently. Hence, the number of people involved can be minimized. The design considers a maximum weight of 2000 N of the coffin, which includes the corpse inside. The device is equipped with a shaft-pulley system, gear, and ratchet mechanism to lower the coffin inside the grave. The strength analysis of the shaft-pulley system by theoretical approach is conducted under static and fatigue loading conditions to estimate the service life. As a result, the calculated safety factor demonstrates a value of more than one, indicating the structure is safe under both static and fatigue loading conditions. Moreover, the device can be operated only by two health workers. In addition, this work is expected to contribute to the innovative idea of engineering products to overcome the Pandemic of COVID-19.

T main purpose of this study is to find out the causes of the respondents’ reluctance to participate in classroom discussions among college students at Notre Dame of Tacurong College (NDTC), enrolled during the academic year 2016-2017. The descriptive method of research is employed to determine the causes of the respondents’ reluctance to participate in classroom discussions. The study is conducted at Notre Dame of Tacurong College (NDTC) with 273 respondents of whom 114 are males and 159 females coming from all courses and year levels. Convenient sampling is utilized to identify the individual respondents from each course included in the study. A researcher-made survey questionnaire that is formulated by the researcher after a review of literature and studies was used to gather data for this study. Statistical tools such as frequency, percentage, mean and standard deviation were used to treat the data. Findings disclose that out of 273 respondents, the majority (58.24%) are female against 41.76% male. As to course, most (18.32%) of the respondents are BSCrim students. As to year level, most (34.43%) of them are second-year students. As to the ethnicity of the respondents, most (47.99%) of them are Ilongos. Further findings show that generally, the investigated causes of students’ reluctance to participate in classroom discussions are moderately prevalent. The top three causes are being tensed when forced by teachers to answer a question; getting tensed and nervous to speak in front of the whole class, and having faulty pronunciation in English. Also, the most popular strategy used by students to participate in classroom discussions is to think carefully about what to communicate before they participate. Based on the major findings of the study, it can be concluded that there are moderately prevalent causes that hinder the participation of some students in the classroom. As a result, several recommendations are offered to academic leaders, teachers, counsellors and students to address the issues so students feel more capable, confident and comfortable to actively participate in their classroom discussions.

Published: January 2022

This study was engaged for assessing the approaches of the barangay officials in mitigating the virus spread in the area through the opinions and experiences of the residents. The study was directed to a new and relevant type of adversity for a virus outbreak that can test the capabilities of the leaders. We utilized phenomenology, wherein narratives have been gathered through interviews. We extracted 5 themes; Erring Situations, Awareness on Precautionary Measures, Approach among Residents, Inequality among Residents, and Discipline. The barangay officials have never failed in implementing necessary protocols. But the protocols may not be sufficient to attain victory. For instance, statements have suggested that constant evaluation through the area should be mandated, and most importantly, the barangay officials should essentially be the first to follow their implementations. Overall, this study impacted the residents by providing a platform to voice out the leadership they received during these trying times.
Permissive Parenting Style and Maladaptive Behavioral Tendencies Among Junior High School Students of Notre Dame of Tacurong College, Mindanao, Philippines
Authors: Cabanatuan Danika , Ahmad Crizjale
Published: January 2022

Parenting style is an essential factor in the development of children's behavior. But, it should research oppositely. This study determined the relationship between Permissive Parenting Styles and Maladaptive Behavioral tendencies. This study answer: (1) To what extent is the respondents' permissive parenting style experienced? (2) To what degree do respondents manifest maladaptive behavioral tendencies? and (3) is there a significant correlation between permissive parenting style and maladaptive behavioral tendencies of the respondents? The study revealed that parents were most likely to have an amiable attitude towards their children. The parents allow them to express their feelings, form their perspectives, and create their own decisions. They somehow showed considerations about their child's well-being and did not tolerate some stuff such as absences and laziness. Despite having a permissive parent, children have cheated on school tests, lied about their age to gain entrance, purchase liquor, take a cigarette, or even steal money from their parents or other family members. Using a permissive parenting style does not have a significant relationship with their kids in developing maladaptive behavioral tendencies. It is recommended to look for other factors contributing to maladaptive behavior since permissive parenting does not affect maladaptive behavior and try to venture into other parenting styles.
Analysis of the Gender Equality Application in Japanese and Indonesian Elementary School Education through Class Pickets
Authors: Mulyahati Tania , Rasiban Linna Meilia
Published: January 2022

In the practice of implementing gender equality, education is one of the receptacles for students to comprehend the implementation of gender equality starting from a very early age. However, many hindrances happened upon the implementation of gender equality on students, especially on elementary school students. The purpose of this research is as stimulation to implement the social reality which became an issue to role holders in implementing character building-related gender equality by observing Japan’s implementation of gender education which can be a reference to look at. The research covering this topic has been done by many. One of them almost publishes a similar topic which was conducted in 2012 which discussed Gender Equality on Education at PPL PGSD-partnership Elementary School. Therefore, the writers try to research this by adding new formula by comparing discoveries in Indonesian and Japanese Elementary School. This research is a combination of descriptive-contrastive methods, historical research, data collecting by interviews on elementary school students, and supported by a few journals which discuss Japanese character building. The results of the research show that Indonesia does not fully enforce gender equality in the education system. This is proven from the daily classroom cleaning schedule which is inversely proportional to Japan’s character building that enforces gender equality, starting from the act of classroom cleaning modelled after the tokkatsu model or educational model. Hopefully, the upcoming researches which study these issues can be a literature study of social symptoms which can meet the solution so this issue can be resolved.

This study’s purpose is to describe the importance of tone indicators in computer-mediated communication through gathering the opinions of high school students. This study employed a generic qualitative approach that allowed us to comprehend five students' perspectives on tone indicators. A thematic analysis helped us to identify significant statements, generate initial themes, formulate, and name relevant themes. The results showed that the participants of the study are not fully aware of tone indicators. In fact, the tone indicators are important, especially facing the problems and applying for facing special needs people. Their narratives indicate that misidentified tones of messages stimulate preconceptions to form in the minds of virtual readers, leading to miscommunication. The students expressed relief, enlightenment, and approval upon the introduction and application of tone indicators. They described the roles of tone indicators as tools to make messages clear. Therefore, tone indicators hold relevance in computer-mediated communication. This study promotes tone indicators awareness and tranquility in online communication.

This study aims to examine the use of virtual reality as a substitute for the pre-school students' field trip activity during the learning from the home period. This research used a literature study as the research methodology. We conducted this study by observing and analyzing several journals on the use of Virtual Reality as a medium of learning. The various results of the journal analysis were used to determine whether virtual reality could be a substitute for the pre-school students’ field trip learning activity in this learning from the home period. By using Virtual Reality, the students would still be able to participate in field trips while still pays attention to the steps of conducting a field trip, such as (1) planning and preparation period; (2) the execution of the event, and; (3) the return time. Besides being considered as an effective tool to increase students’ learning interest and improve their learning outcomes, virtual reality can also be a substitute for the real field trips during this Covid-19 pandemic. Therefore, the students do not need to leave the house to participate in field trips. Hopefully, the result of this research would be able to provide the readers with new insights and knowledge on the utilization of virtual reality as a substitute for the pre-school students’ real field trip activity especially in this learning from the home period.

The energy crisis is a serious issue that all countries around the world are dealing with, particularly the energy sources used to generate electricity. There are numerous alternative energy sources available in nature, such as solar energy, wind energy, and so on. Wind and solar energy as hybrid energy sources are thought to be promising in electric generation technology. Hybrid Power Plants can also be used to address the issue of limited electrical energy supply in Indonesia's remote areas. The purpose of this study is to describe the effectiveness of the hybrid power plants implementation in Indonesia. The study was conducted using the narrative literature review method. It can be inferred that the purpose of developing this hybrid technology, among others, is to obtain more efficient electrical energy generation by combining the advantages of two or more types of power generation systems that work in an integrated manner as a compact system. The produced electric energy can be stored in the battery. In terms of use, the produced direct current (DC) is converted into alternating current (AC) using the inverter system prior to distribution to consumers. Therefore, this hybrid power plant is suitable to be implemented in Indonesia.

Published: January 2022

This research focuses on finding solutions to get around the energy crisis. This study aimed to know the effectiveness of household waste (vegetable waste) biogas using a starter mixture of cow dung and EM4. What is new from this research is the use of household waste as biogas energy. The research method used is the study of literature from various journals and articles, accurate and reliable. Various journals and conceptual articles were obtained from google scholar and the liputan6.com website page. From the experimental results, the more the composition of vegetable waste, the higher the pressure, but the less the flame. Based on the research results, it can be concluded that biogas made from vegetable waste alone is quite effective to be used as a solution to the energy crisis problem (to replace LPJ gas, to be precise) because of the large amount of methane produced. However, if we are want to be an innovation for successful village development, biogas from household waste (vegetable waste) can be used by adding cow dung as the main ingredient. So that methane is produced in large quantities according to the amount of material used.
