Abstract

The transesterification of Calophyllum inophyllum seed oil into biodiesel using Javanese Moringa oleifera leaf ash catalyst with various reaction conditions has been completed. MA-500 (Moringa ash at 500°C for 3 h) and MA-900 (Moringa ash at 900°C for 3 h) catalysts were obtained by grinding Javanese old Moringa oleifera leaf (MP) and then calcined for 3 h at 500 and 900°C. The crude Calophyllum inophyllum seed oil was degummed (OD) prior to continue the esterification process (ODE). The MA-500 and MA-900 catalysts were tested for their activity and selectivity through the ODE transesterification with various catalyst weights (3, 6, and 9% (w/w)), reaction temperature (55, 60, and 65°C), oil: methanol mole ratio (1:3, 1:6, and 1:9), and reaction time (60, 90, 120, and 150 minutes). The results showed that the MA-500 and MA-900 catalysts contained 18.17% and 52.91% Ca respectively. The esterification reaction could reduce FFA levels to 89.82%, from 19.46% to 1.98%. ODE transesterification with MA-900 catalyst optimum reaction conditions with a catalyst weight of 3%, reaction temperature of 60°C, oil: methanol mole ratio of 1:9, and reaction time of 120 min, 76.17% FAME yield was observed. The MA-900 catalyst has the potential to be an effective green catalyst.

Abstract

The research aims to study the effects of Mo metal embedded on H-Mordenite on its activity and selectivity of hydrodeoxygenation (HDO) for Refined Palm Kernel Oil (RPKO) into bioavtur. The RPKO was obtained from the results of degumming and bleaching process of palm kernel oil and then analyzed using Gas Chromatography-Mass Spectrometer (GC-MS). The impregnation of Mo metal was carried out by spraying using an ammonium heptamolybdate precursor solution ((NH4)6Mo7O24•4H2O) with an initial Mo metal content of 5, 10, and 15wt% of H-Mordenite to produce 5-Mo/Mor, 10-Mo/Mor, and 15-Mo/Mor. The 15-Mo/Mor catalyst produced the highest amount of liquid product (46.08wt%) with bioavtur yield of 43.19wt%. The usability test showed that 15-Mo/Mor catalyst still produced a good performance after three times of use in the RPKO feed HDO with the second and third run test liquid product of 34.82 and 46.14wt% respectively with bioavtur yield of 32.58 and 43.45wt%, respectively.

Abstract

A significant quantity of abandoned waqf lands in Indonesia is evidence that the optimal management of waqf has yet to be achieved. The primary objective of this study is to identify and analyze the existing research lacunae in prior studies, hence facilitating the delineation of future research directions. The employed research methodology utilizes a quantitative approach, wherein publications are quantified using the publish or perish tool and analyzed using the Vosviewer software afterward. This study employs the terms "waqf management" OR "waqf management" AND Indonesia to search for papers inside the Scopus database, focusing on the research period from 2015 to 2022. The study yielded a total of 14 papers about the management of waqf. These articles were categorized into four distinct research areas, namely: (1) the enhancement of productive waqf, (2) the administration of the waqf system, (3) the legal aspects of waqf, and (4) crowdfunding through Sukuk. Based on the four themes above, it is evident that the advancement of productive waqf has been implemented throughout many waqf institutions in Indonesia, yielding favorable outcomes in enhancing the socio-economic conditions of impoverished individuals.

Abstract

Thermal and microstructure analysis of cocofoam made from vulcanized coconut fiber and latex compound were conducted. The cocofoam was produced by blending coconut fiber and latex compound with weight ratio of 10/25 (CF5-1) and 20/55 (CF5-2) at room temperature. The cocofoam characters were then analyzed by Scanning Electron Microscope (SEM), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DTA) instruments. The result showed that the increase of coconut fiber and latex compound ratio produced a higher density of cocofoam. The highest value density was 0.6920 g/cm3 with flexibility of 90% produced by the CF5-2 sample. The SEM analysis showed that both specimens surface of the CF5-1 and CF5-2 samples have different pores size and the latex compound is not distributed thoroughly in the cocofoam. The thermal analysis showed that the production of cocofoam was largely determined by latex compound that served as fiber binder matrix. Cocofoam started to degrade at the temperature of 90°C and was damaged when it was heated at the temperature of 115°C for 2.5 hours.

Abstract

Student learning outcomes are influenced by various factors, one of which is the teaching method applied. In science education, the role of the teaching method is crucial in determining students' success in achieving the expected learning outcomes. However, the issue at hand is the lack of technology use in the classroom and the low motivation of fifth-grade students in engaging with lessons. This study aims to examine the impact of differentiated learning with Canva media on motivation and learning outcomes in science (IPAS) for fifth-grade students. This study employs a quasi-experimental design with a pretest-posttest and control group. The research involved 30 students, divided into two groups: 15 students in the intervention group and 15 students in the control group. Motivation and learning outcomes were measured using a validated and reliable questionnaire. Data were analyzed using paired T-tests and Independent Sample T-tests. The subjects' age ranged from 10 to 11 years. The results indicate a significant difference in the mean motivation difference between the intervention group (95.20±2.731) and the control group (87.07±5.725), with p = 0.000. Furthermore, there was a significant difference in the mean learning outcomes before and after the intervention in each group, with the intervention group achieving 84.33±3.716 (p = 0.000) and the control group achieving 70.67±8.209 (p = 0.003). The learning outcomes in the intervention group also showed a significant improvement compared to the control group (p = 0.000). The conclusion of this study is that differentiated learning using Canva media can significantly improve motivation and learning outcomes in fifth-grade students, making it an effective method for implementation in teaching.

Abstract

This research explores the latest in information decentralization using blockchain technology in e-journal applications. Using a Partial Least Squares Structural Equation Modeling (PLS-SEM) approach via SmartPLS, this research integrates variables such as Data Security (KD), Information Transparency (IT), and User Participation (PP) to measure the direct and indirect influence ofblockchain technology . Data was collected from 250 respondents consisting of researchers, developers and end users of e-journals. Analysis shows that Data Security (KD) plays an important role in increasing Information Transparency (IT) with a path coefficient value of 0.75. Furthermore, Information Transparency (IT) significantly influences User Participation (PP) with a pathcoefficient value of 0.65. These results suggest that blockchain implementation not only improves data security, but also facilitates greater transparency, which in turn increases user participation in e-journals. This research makes an important contribution to the literature by showing how specific variables can be leveraged to optimize the application of blockchain technology in the context of e-journals.
