Abstract

Turmeric contains bioactive compounds that are efficacious for human health. A breakthrough of simpler and lower-cost identification techniques is needed to utilize it. This paper aims to investigate the development of chemo-selective gas sensors for identifying α-curcumene, ar-turmerone, curlone, and β-sesquiphellandrene. Four chemo-selective sensors were created using quartz crystal microbalance (QCM) sensors coated with molecularly imprinted polymers to identify each of those compounds. The polymers were prepared using polyacrylic acid, hydrochloric acid, and pure target compounds (α-curcumene, ar-turmerone, curlone, and β-sesquiphellandrene). The turmeric odor from 10 different samples was exposed to QCM sensors. The changing frequency of QCM sensors due to the mass loading of target compounds on the surface of QCM sensors was recorded to analyze the performance of QCM sensors. The result of the principal component analysis showed that the QCM sensors performed well and could distinguish the turmeric samples at five combinations of the compounds. The turmeric sample classification using backpropagation neural networks reached high accuracies, with 97.04% in training and 98.73% in testing datasets. These findings indicate that the employment of sensory analysis using QCM sensors has the prospect of being a complementary technique for identifying bioactive compounds.

Abstract

Perfume is a cosmetic product that widely used by people to improve their appearance in social interactions. Perfume released specific fragrance from the essential oil. Manufacturers often mix the pure essential oils with hexylene glycol to reduce prices. Utilization of hexylene glycol as the solvent and diluent often reduce the odour profile of the perfumes. This paper investigated the development of an electronic nose (e-nose) based on a metal oxide semiconductor (MOS) gas sensor to detect hexylene glycol in perfumes. E-nose in this study was developed using MOS gas sensors from Figaro and Raspberry series, including TGS 822, TGS 826, TGS 2600, TGS 2620, MQ2, MQ3, MQ8, and MQ135. For the experiment, we collected 10 brands of commercial perfumes from the supermarket around Purwokerto, Central Java. All samples of perfumes were analysed using gas chromatography-mass spectroscopy (GC-MS) to detect the concentration of hexylene glycol in the samples. The concentration of hexylene glycol in the samples identified none (0%), low (1-20%), moderate (21%-50%) and high (more than 50%). Afterward, 10 brands of perfumes were separated into 15 samples, totally created 150 samples. All perfume samples were measured using an e-nose to obtain the responses. Analysis of sensor responses using principal component analysis (PCA) showed that e-nose was highly performed to discriminate the samples based on hexylene glycol concentration. Classification of 150 perfume samples using backpropagation neural networks (BPNN) grouped 150 perfumes in four different classes in which the accuracy of classification reached 96.36% for the training dataset and 92.50% for the testing dataset, respectively.

Abstract

This experimental study employed nonequivalent control group design to examine the effect of the flipped classroom method on students’ achievement in Islamic education learning among grade XII students at SMA Negeri 1 Sumpiuh in 2024. The flipped classroom method was implemented by instructing students to study the material independently through learning videos followed by elaboration and discussion through online platforms. For data analysis, tests were administered to 30 students in the experimental groupand 30 students in the control groups. The results of the N-gain Score calculation showed that the improvement in material comprehension among students in the experimental group was higher than that of the control group. The N-gain score for the experimental group students was 0.3562, while that for the control group was 0.1511. Statistical analysis using an independent samples t-test showed that the comprehension ability of the experimental group was significantly higher than that of the control group (p > 0.05). Based on these findings, the flipped classroom method can be considered an effective alternative strategy to enhance students’ understanding of learning materials in online Islamic education.

Abstract

The transformation of digital learning media has emerged as a central focus in Indonesia’s educational landscape, particularly at the elementary school level. This study aims to examine the implementation of digital learning media grounded in local wisdom as a strategic effort to enhance learning effectiveness. A qualitative research design was employed, utilizing data collection techniques such as interviews, observations, and document analysis in selected elementary schools that integrate local wisdom into their instructional practices. The findings reveal that the use of digital media incorporating elements of local wisdom not only increases students’ interest and motivation but also contributes significantly to strengthening their cultural identity. Furthermore, the data indicate that 75% of students reported higher levels of engagement when digital learning media were used effectively in the classroom. The study also highlights that teachers who have received adequate training in the use of digital technologies demonstrate greater proficiency in adapting instructional materials to reflect local cultural values. Overall, the transformation of digital learning media is expected to serve as a promising approach for improving the quality of elementary education while simultaneously preserving local wisdom in the face of rapid globalization.

Abstract

Transformation of GP Anshor's Cadre Education MThe rapid expansion of digital technology has reshaped the communication landscape of religious organizations, requiring adaptive strategies in both da’wah practices and cadre education management. This study examines how GP Ansor, an Islamic youth organization in Indonesia, integrates digital media into its organizational practices in response to the dynamics of the information disruption era. Using a qualitative case study approach, data were collected through in-depth interviews, documentation analysis, and digital observation of social media platforms, including Instagram, YouTube, and Twitter/X. The findings reveal that GP Ansor has developed a multifaceted digital da’wah strategy by optimizing social media, establishing counter-narratives against radicalism through structured cyber initiatives, and implementing digital literacy programs as part of its cadre development process. Furthermore, digital learning practices have expanded beyond formal training into interactive and participatory online spaces, allowing cadres to actively engage in content production and public discourse. However, the study also identifies several challenges, including disparities in digital competencies among cadres, limitations in technological infrastructure, and the lack of systematic evaluation mechanisms. These findings highlight that digital transformation within religious organizations is not merely a technological shift but involves a reconfiguration of learning processes, organizational structures, and human resource development. The study contributes to the field of Islamic education management by offering insights into how digital-based cadre education can be designed to remain adaptive, sustainable, and aligned with the promotion of religious moderation in contemporary digital environments.anagement Strategy

Abstract

Since 1968, socio-economic and infrastructure development focused on the accessible region such as urban and sub-urban area. Rural, rim-land, coastal area, highland, and isolated area were still ignored in national development priorities by the central and local government. This paper discusses the spatial analysis of disparities in Banyumas Regency, Central Java, based on indicators of socio-economic and infrastructure. We had collected data by doing a survey in 27 sub-districts in Banyumas Regency. Disparities in socio-economic development and infrastructure were measured using 14 variables, i.e. unemployment rate, consumer price index, wage index, poverty index, quality of life, quality of health, quality of education, criminal rate, quality of roadway, public transportation accessibility, quantity of traditional market, quantity of bridge, and the quantity of public school building. Multivariate statistical analyses based on the principal component analysis (PCA) and hierarchical cluster analyses (HCA) were used to analyze the disparities. The analysis on 14 socio-economic parameter displays that unemployment rate, poverty index, quality of health, and quality of education are the main contributor for socio-economic and infrastructure disparity. Ajibarang, Gumelar, Cilongok, and Rawalo had still a classic problem in economic development due to being the pockets of unemployment and poverty in Banyumas Regency. Based on social indicators, 6 sub-districts including Gumelar, Karanglewas, Lumbir, Pekuncen, Somagede, and Tambak should receive more attention by local government due to a high percentage of poor people to access medical and health facilities. In addition, the ratio of people who are able to access higher education in Jatilawang, Purwojati and Wangon was still less than 10%. There were no significance disparities in infrastructure indicator because the infrastructure had been developed equally in all sub-districts in Banyumas Regency.
