The objective of this study was to analyze machining performance (characteristic and quality), as well as bonding quality of densified wood, and then compared to those of un-treated (control) wood and boron-treated wood. Characteristic and quality of machining properties were directly evaluated by qualified technician during processing, while bonding quality was evaluated through its shear strength. The results showed that densification employed was able to improve machining performance and bonding quality of the 5-year-old faster-grown teakwood. Compared to control wood and boron-treated wood, machining performances of densified teakwood are greater, while bonding quality increased by 18.79 and 26.86%, respectively. The surface became much fine and even, and has similar colour to older teakwood. Analysis hierarchy process (AHP) proves that densified teakwood is the best raw material for furniture manufacturing since its machining performances, appearance, colour, and bonding quality are better either than control wood or boron-treated wood.

The source of iron in waters can come from human activities that carry out activities such as waste disposal in household and industrial activities. Green mussels containing iron are very dangerous for the shells themselves and for human health if consumed in excess. This study aims to analyze the concentration of iron in green mussel meat, determine the safe limit of green mussel meat for consumption by humans, and calculate the value of bioconcentration factors. This research was conducted in the sea of Tanjung Mas, Semarang. Samples taken in the form of green mussels, sediments, and water were then analyzed for iron concentrations with Atomic Absorption Spectrophotometer. The results of the study showed that the range of iron concentration values in green mussels from July to November was 39–283,97 mg/kg. The range of MTI values for adults was 1.18–4.92, while for children the range was 0.24–0.98. The value of the bioconcentration factor of green mussels and water was 3271–24839, while the value of the bioconcentration factor of green mussels and sediments was 0.010–9.647.

Fertilization is needed to support the growth of soybean plants. Nitrogen is a type of fertilizer that is needed by soybeans in considerable amounts. Aplication of nitrogen at different times is able to affect the production and quality of soybean seeds. The purpose of this study was to attain information about the morphology, physiology, and production responses of two soybean varieties to the supply of N. This research was conducted at the Cikabayan Experimental Station, IPB University, Dramaga, Bogor Regency. This study used a completely randomized block design with two factors, namely two soybean varieties consisting of Tanggamus and Biosoy 1, and four combinations of N fertilizer doses that were without N fertilization, fertilized N at planting date, fertilized N at the seed filling phase, and fertilized N at planting date+seed filling phase with two replications. The dosage of urea fertilizer used was 25 kg ha-1, so that the N dosages is obtained 11,5 kg ha-1. The results showed that the application of N fertilizers at planting and during the seed filling phase (N3) was an effective time to increase soybean production.

Phytotoxicity of soil aluminum (Al), both directly to the plant growth as well as indirectly through the increase of soil potential acidity, is closely related to the occurrence of various soil soluble-Al species. Amongst them, Al3+ and monomeric-Al species are the primary causes of Al phytotoxicity in soils with high Al content. This study was aimed to evaluate the effects of soil amelioration with dolomite and base-activated lignite (BAL) on changes in soluble-Al species and other soil chemical properties, and vegetative growth of soybean (Glycine max Merr) on Ultisol of Jasinga (Al-dd 16,03 cmol(+)/kg). A green house experiment was conducted by applying a Completely Randomized Design with dolomite and BAL amelioration as the treatments, each with three levels of repectively 0, 1, 1,5 x exchangeable-Al and 0, 2,5, 5 tons BAL ha-1, and three replications. The ameliorants were incubated at field capacity of soil moisture content for one week before planting soybean for one month. Soil soluble-Al speciation was carried out using colorimetric aluminon method to determine concentrations of total soluble-Al, monomeric-Al, and polymeric-Al species. Monomeric-Al were further speciated into inorganic monomeric-Al and organic monomeric-Al species. The results revealed that only dolomite amelioration that significantly increased soil pH-H2O, pH-KCl, Ca- dd, Na-dd, and decreased exchangeable-Al concentration, except for those of all soluble-Al species that only showed a decreasing trend. Soil exchangeable-Al that was negatively and significantly correlated with soybean measure parameters were plant height, root length, total roots and shoots wet and dry weights, as well as Ca concentration. These results indicated that soil Al phytotoxicity evaluation could be relied on the result of routine analysis on soil exchangeable-Al concentration.

Authors: Bollido Marcos Erram 
Published: January 2021

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.

Lake Matano is an ancient lake that has a high endemicity. Opudi fish (Telmatherina prognatha) is an endemic fish that is vulnerable to extinction and needs to be preserved. The threat of invasive species and habitat degradation can cause a decrease in opudi fish populations. This study aimed to examine the growth parameters associated with growth coefficients and mortality in Lake Matano so that population can be sustainable. The study was conducted at Lake Matano from March 2018 to February 2019. Samples of fish were caught using a net bag measuring 30 m long, 2 m wide with a mesh size of 0.5 inches. Analysis of fish growth was based on total length-frequency data. These data were analyzed using the FISAT II software. The sizes of male and female opudi fish obtained ranged from 30-70 mm. Growth patterns of von Bertalanffy butina in male fish are male Lt = 76.50 [1-e-0.46 (t + 0.47)] and female fish Lt = 74.05 [1-e-0.51 (t + 0.52)]. The total mortality value of male fish was higher (Z = 1.65) compared to female fish (Z = 1.50), the natural mortality value of male opudi fish was lower (M = 0.84) compared to that of female fish (M = 0.91).

Rice is a staple food for most Indonesian population. Nowadays, people want staple foods that are not only filling but also do not increase blood sugar concentration (low glycemic index). One of foods that contain higher starch, lower glycemic index, and higher fiber than rice is white corn. The white color of the corn is an advantage because if it is made in grits it can resemble rice. Weakness of white corn is harder than rice. To soften and make it easier to consume, it is coated with an edible packaging made from tapioca. The purposes of this study were to study (1) the quality of dried corn rice from local white corn Anoman 1 variety in edible packaging with packaging thickness of 0.7, 0.9, 1.1, 1.3, and 1.5 mm; (2) the quality of cooked white corn rice produced. The results showed that the thickness of the edible packaging significantly affected (1) the moisture, ash, protein, fat, and carbohydrate contents of dried white corn rice and (2) all parameters of cooked white corn rice (a = 0.05). The best cooked corn rice based on the stickiness test was found in coated dried corn rice with edible packaging with a thickness of 1.5 mm. Characteristics of (1) dried white corn rice contained 11.39% water, 0.21% db ash, 15.23% db protein, 0.53% db fat, 72.64% carbohydrates, 2.11% crude fiber, (2) the quality of cooked of white corn rice were 18.17 g / mm2 stickiness, yellowish color (score 1.1), slightly distinctive aroma of corn (score 2.5), slightly fluffier texture (score 3.4), and rather strong sweet taste (score 2.8).

Background: The aimed of this study was to identify and ranking noise control solutions by using fuzzy Delphi approach and FAHP-fuzzy vikor method in an oil refinery.
Methods: This descriptive-analytical study was conducted in the catalytic conversion unit in an oil refinery. First, noise measurement was performed based on the standard to identify the sources of noise generating factors. Second, the criteria and initial solutions were identified by reviewing the texts and conducting interviews with experts and the most significant criteria and solutions for noise control were selected using the fuzzy Delphi method. Then, the criteria were weighed using the fuzzy analytic hierarchy method. Finally, the control solutions were prioritized using fuzzy Vikor method.
Results: The results of FAHP method indicated that cost with final weight (0.2796) had the highest weight and non-interference in the process with final weight (0.1107) had the lowest weight among the identified criteria. The ranking of noise control solutions with fuzzy Vickor method indicated that the construction of an acoustic room for workers exposed to weights (Q = 0) as the most appropriate solution for noise control and the method of modifying or changing the work process with the final weight (Q = 1) is the last noise control solution among the solutions identified in the studied refinery.
Conclusion: The use of multi-criteria decision-making methods in selecting the appropriate solution for noise control can overcome the uncertainties in making an appropriate decision for selecting the best solution for noise control. In this study, a decision model was introduced for selecting the most appropriate noise control solution based on different criteria and this model can be used in other industries which should select a noise control solution.
Implementing Portfolio-Based Learning (PoBL) for L2 Training: Vietnamese EFL Learners’ Motivational Orientations and Listening Achievement
Authors: Cong-Lem Ngo 
Published: January 2021

Whilst previous researchers commonly report on the effect of portfolio-based instruction on L2/EFL (second language/English as a foreign language) learners’ language performance, very few studies examine its impact on their learning motivation. Drawing on expectancy-value theory, the current study examines how the implementation of a portfolio-based listening course may affect language learners’ L2 motivation and skill development. This study adopted a mixed method approach with Vietnamese EFL learners in higher education as its participants who were administered a motivation questionnaire, listening comprehension tests, and semi-structured interviews. Both quantitative statistics and qualitative content analysis were applied for data analysis purposes. The results indicated that the portfolio-based program in this study had a significant positive impact on the participants’ motivational orientations, especially their expectancy components (i.e., their self-efficacy and learning control beliefs) and their L2 listening accomplishment but not on the value aspects. Pedagogical implications are discussed.
Alors que les chercheurs précédents font des rapports fréquents à propos des incidences sur la performance langagière des apprenants de L2/ALE (langue seconde/anglais langue étrangère) qu’a l’instruction basée sur le portfolio, très peu d’études examinent son impact sur leur motivation d’apprentissage. En s’inspirant de la théorie de l’expectancy-value, la présente étude examine comment la mise en place d’un cours d’écoute basé sur le portfolio peut affecter la motivation et le développement des compétences des apprenants de langue seconde. Cette étude a adopté une démarche à plusieurs méthodes auprès d’apprenants universitaires d’anglais langue étrangère vietnamiens à qui on a administré un questionnaire de motivation, des tests de compréhension orale et des entrevues semi-structurées. On a appliqué à la fois des statistiques quantitatives et une analyse qualitative du contenu à des fins d’analyse des données. Les résultats ont indiqué que le programme de cette étude, basé sur le portfolio, avait un impact positif significatif sur les orientations motivationnelles des participants, particulièrement sur les composantes de leurs attentes (c’est-à-dire leur efficacité personnelle et leurs croyances dans le contrôle de l’apprentissage) et leurs résultats d’écoute, mais pas sur les aspects de valeur. On discute des implications pédagogiques.
The Quranic Treatment of Extremism

Published: January 2021

This study deals with the Quranic treatment of extremism in terms of extremisms concept and semantics, types, causes, images, and the Quranic approach in its treatment, and we try to link the Muslim to the Quran approach in the treatment of extremism as a problem which the individual and the old and new society suffer; Because extremism can be transformed from mere idea to apparent behavior while demonstrating that extremism in fact transcends the rules of law and divine orders, it is excessive in the commitment to religion on the one hand or negligence in adhering to it, on the other hand, it is not always concerned with bringing the matter but also enters into relinquishing. In addition to the need to be warned that extremism is a method of religiosity and not religion itself, and Islam with its centrist approach rejects such practices and seeks to address them through the curriculum of the Holy Quran

Abstract
The ionizing radiation shielding parameters of (90-y)TeO2-yV2O3-5CaO-5Na2O (TVCN): y = 5–20 mol% semiconductor glasses were investigated. The avarage track lengths of photons with different energies (0.015- 15 MeV) in the TVCN-glasses were simulated via MCNP-5 code, then the corresponding LAC were computed. Based on LAC values, the MACs were calculated and compared with values which obtained via XCOM software. The highest LAC achieved for low energy (0.015 MeV) and reduced from 199.549 to 169.891 cm− 1, while the lowest values achieved for gamma photon with higher energies and reduced from 0.188 to 0.161 cm− 1 with replacment of TeO2 compound by V2O5. The highest (I/Io) achieved for TVCN20 glasses and decreased from 0.703 to 0.172., while the lowest (I/Io) performed for TVCN5 glasses and decreased from 0.680 to 0.145 for glasses thickness varied between 1 and 5 cm. The thinner HVL was achieved for TVCN5 and increases from 0.003 to 3.684 cm, while the thicker HVL was achieved for TVCN20 and increases from 0.004 to 4.293 cm. The highest dose rate was recorded in the presence of theTVCN20 glasses and varied between 5.680 and 23.210 µSv/hr, while the lowest dose rate recorded in the presence of the TVCN5 glasses and varied between 4.807 and 22.448 µSv/hr for glass thickness varied in range between 1–5 cm. The highest values of the Zeff was recorded for glasses TVCN5 and varied between 21.209 and 50.402, while the lowest Zeff achieved for TVCN20 and varied between 18.489 and 40.479. The calculated buildup factors (EBF and EABF) reach maximum values for glasses TVCN5 while the lowest EBF and EABF achieved for glasses TVCN20. Therefore, the glasses TVCN5 have a higher ability to attenuate the incident gamma photons. Thus, the TVCN-glasses can be applied in various radiation shielding applications in medical area.

Abstract
PurposeIt was aimed to examine the reliability and validity of the Orthorexia Nervosa Inventory (ONI) the Turkish version in a large adult population.MethodsIn this cross-sectional study, 710 individuals were included between the ages of 18–65 years living in Turkey. Individuals were reached via an online questionnaire (including ONI, Eating Attitudes Test-26 (EAT-26) and sociodemographic characteristics). Confirmatory factor analysis (CFA) was used to test the validity of ONI. ONI contains three sub-factors (behaviors, emotions and impairments). Analyzes were made with Lisrel 8.80 program and Statistical Package for Social Sciences 22.0 package program.ResultsThe Cronbach’s alpha coefficient was 0.906 for ONI total factor scores and Cronbach’s alpha values for “behaviours”, “impairements”, and “emotions” were found to be 0.821, 0.842, and 0.809, respectively. Confirmatory factor analysis performed supported the three-factor structure of the ONI obtained in the first sample. The CMIN / df = 5.65 and the model generally fits well to the structure (RMSEA = 0.081, CFI = 0.94, NFI = 0.91, GFI = 0.86, AGFI = 0.83). A positive and moderate relationship (r = 0.418) was found between ONI and EAT-26. A positive and low level (r = 0.160) correlation was found between ONI and body mass index. There is no statistically significant difference between ONI scores according to gender (p = 0.22).ConclusionThe findings suggest Turkish version of the ONI is a valid and reliable scale for determining the tendency for orthorexia nervosa in Turkish adult population.Level of evidenceLevel V, descriptive cross-sectional study
