– Experimental activities in physics learning are important to encourage students to interact directly with physical phenomena. This study integrates local culture with technology through an innovative approach to the design of physics experiments. Arduino, a low-cost microcontroller, is extensively utilized for learning physics. The local culture examined in this study is Angklung, a traditional musical instrument from West Java, Indonesia. This study utilizes Arduino with a microphone sensor to design experiments investigating the sound produced by Angklung. The experimental activity aims to determine the frequency generated on each musical instrument on the diatonic Angklung and the factors that influence that frequency. The experimental results show that each musical instrument has a different frequency. Programming on Arduino is easy for students even though students do not have basic programming knowledge. The results of this study can be used as a reference for conducting alte.....

The main aim of this article was to see the public space of Pesantren as an arena for negotiating Islamic moral ideas and modernity. The practice of dating in Islamic literature is linked to immoral action because it is contrary to Islamic teachings that prohibit relationships outside marriage. It has become an important part of Islamic moral education. Dating in Pesantren is prohibited, and it is a relationship outside marriage. However, there are still many students who develop romantic relationships with members of the opposite sex in the public spaces of Pesantren. Through ethnographic studies, researchers observed Santriwati’s dating practices and interviewed them to determine the moral basis for these actions. Based on these observations at the Pesantren Madrasah Ulumul Qur’an (MUQ) Langsa, the practice of dating was carried out by santriwati by hiding behind buildings and rooms in the Islamic boarding school. This secretive and tactical action was carried out not to confront.....

In this study we discuss the relationship between the concepts of abundance, peace and painting. After a general look at different definitions and approaches to the concept of abundance, we will choose the cultural and artistic approach and, in this context, take a brief look at the painters who used the concept of abundance together with peace. Then we will look at the style of Florescencism, invented and introduced by the contemporary painter Lida Sherafatmand, and the related paintings that have been shown in many prestigious exhibitions around the world, in the context of one of the main approaches of this style, which is to represent the concept of abundance. The abundance of fresh and bright flowers with vivid and promising colors in Lida Sharafmand’s paintings is formally and conceptually in line with one of the clauses of the Florescencism manifesto, which refers to the concept of abundance as a way to develop peace. The paintings selected and presented in this review have be.....

This study examines the efects of washing pretreatments on the chemical characteristics of biomass and the resultant biochar derived from empty fruit bunches (EFBs) of palm oil plantations. We optimized parameters such as washing duration, techniques, and water volume to improve biochar quality. Following the washing pretreatment, the EFBs were subjected to slow pyrolysis at 500 °C for 2 h under a nitrogen atmosphere. In-depth analyses employing techniques like X-ray fuorescence (XRF), X-ray difraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA-DTG), and inductively coupled plasma mass spectrometry (ICP-MS) demonstrated profound changes in the EFB biomass and biochar structure and composition. Specifcally, the sample L-EFB4, soaked in water for 72 h, showed a 67.08% reduction in ash content and a signifcant decrease in potassium content, enhancing the biochar’s.....

This study is a development research which proposes to create a digital platform to enhance digital literacy concerning landslide disasters for Generation Z. The findings indicate that in Semarang City, Generation Z frequently accesses information from the internet and finds it extremely helpful. However, their knowledge and literacy regarding preparedness for landslide disasters remain low, which highlights their need for a digital literacy platform on this topic. Based on this requirement, the researchers developed the SiAlong platform, short for "Landslide Preparedness Information System". This platform is a website accessible by users on various devices, including Android and iOS smartphones, as well as computers, laptops, PCs, and tablets. To date, the availability of digital platforms for information and education on landslide disasters is very limited. Digital technology is predominantly used for developing sensing systems, detection, prediction, or monitoring of landslide disas.....

This study investigates biomaterial composites made from a poly(lactic acid) (PLA) polymer matrix and hydroxyapatite (HA) extracted from fish scales (FsHA) for biomedical applications, especially in 3D printing. Fish scale HA is considered a halal alternative to synthetic or bone-derived HA. The research aims to explore the chemical, mechanical, and thermal properties of PLA/FsHA composites. Samples were prepared by melt-blending PLA with varying FsHA weights (10-50 wt%) at 190 °C, followed by hot pressing. Mechanical properties were analyzed using tensile tests, while scanning electron microscopy (FESEM) characterized the morphology of fractured specimens. Fourier transform infrared spectroscopy (FTIR) studied the functional groups between PLA and FsHA. Thermal properties, including glass transition temperature (Tg) and melting temperature (Tm), were investigated using differential scanning calorimetry (DSC). Mechanical analysis revealed that optimal properties were achieved at 20 wt.....

A series of mixed glass formers (MGF) with varying compositions denoted as (79-x)B2O3-xTeO2-20Li2O-0.5Ho2O3-0.5Yb2O3 (x = 0–50 mol%) were prepared using the melt-quenching technique. This aim of this study was to examine the effect of combining glass formers TeO2 and B2O3 on the structural, DC conductivity, elastic, and optical properties of the glass system. XRD measurements confirmed the amorphous nature of the glass samples. Structural analysis revealed a rivalry between the TeO2 and B2O3 formers. It was observed that the bridging oxygen (BO) indicated by the BO4 functional group decreases gradually at x ≥ 40 mol%, implying that non-bridging oxygen (NBO) units, denoted by BO3, become dominant beyond 40 mol%. The variation in DC conductivity showed a non-linear behaviour upon addition of TeO2, with the conductivity increasing to a maximum value at x = 30 mol% before decreasing at x > 30 mol%. Interestingly, the conductivity showed a slight decline at x = 40 mol%, possibly r.....

Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) are involuntary by-products of incomplete combustion and are highly toxic to humans and the environment. The Malaysian peat is often acidic or extremely acidic having high levels of chlorine and/or other organic acids that act as catalysts or precursors in PCDD/Fs formation. This study aims to predict PCDD/Fs emissions in peat soil using an artificial neural network (ANN) approach based on limited emission data and selected physico-chemical properties. The ANN's prediction performance is affected by uncertainties in its initial connection weights. To improve prediction performance, an optimisation algorithm, termed differential evolution (DE), is used to optimise the ANN's initial connection weights and bias. The study adopts several ANNs with fixed architecture to predict PCDD/Fs emissions, each consisting of a multilayer perceptron (MLP) with a backpropagation algorithm. Eight input variables and one output.....

This research is based on a gap in authority between men and women in making investment decisions where women are considered less financially literate and less struggling. Therefore, this study examines how financial literacy and trust affect women’s investment decisions in Sharia instruments with financial spirituality orientation as a moderating factor. The sample was selected from 256 women on the northeastern coast of Central Java, Indonesia. Structural Equation Modeling with a Partial Least Square method was used to test the data. The findings showed that the higher the financial literacy, trust, and financial spirituality orientation, the better the decision level in the Sharia investment decisions. The financial spirituality orientation strengthens the influence of financial literacy on Sharia investment decisions. However, financial spiritual orientation cannot intervene in trust in financial institutions. This finding suggests that women consider their spiritual beliefs whil.....
