This study aims to identify and describe the mathematical values contained in Balikpapan culture through an ethnomathematics study. This study employed a qualitative appr…

The main protein of SARS-CoV-2 with PDB ID 7Q5F is one of the important targets in the development of antiviral drug candidates. This study aims to evaluate the potential of natural compounds from gambir (Uncaria gambir) in inhibiting the activity of the 7Q5F protein through the molecular docking method. The protein and ligand structures were prepared using MOE 2022 software, followed by docking …

Clean water is a basic need for the survival of living beings and constitutes an important aspect of public service provision, particularly for PDAM in improving service levels for the community. The demand for drinking water in a region continues to increase along with population growth, making it necessary to conduct a measurable analysis of clean water needs and availability. This study aimed …

The application of digital technology in construction is developing through the integration of Building Information Modeling (BIM) and Augmented Reality (AR), particularly to improve the effectiveness of quality control during the project implementation stage. However, the implementation of AR in construction work still faces obstacles, particularly related to workflow integration, human resource…

Dry hair is often experienced by female students who actively use high-temperature hair styling tools in beauty practice, causing the hair to become dull, brittle, and easily damaged due to the reduction of its natural moisture. One effort that can be made to address this condition is the use of a hair mask made from natural ingredients that is safe and environmentally friendly. This study aims t…

Although the use of digital technology in learning continues to develop, the development of interactive learning media that meet the valid and practical criteria for the topic of Sensor and Transducer Circuits still requires attention. This study aims to design and produce interactive learning media based on the Canva application that meet the valid and practical criteria for eleventh-grade stude…

Environmental pollution by heavy metals, particularly Zn2+ ions, has become a serious problem due to increasing industrial activity and their potential toxic effects on ecosystems and human health, thus requiring effective and selective separation methods. This study aims to analyze the effect of variations in the amounts of methacrylic acid (MAA) as the functional monomer and ethylene glycol dim…

The successful synthesis of Ion Imprinted Polymers (IIPs) is strongly determined by the selection and ratio of the functional monomer and crosslinker because these two components directly affect the resulting adsorption capacity. An inappropriate composition, whether too low or too high, can reduce adsorption performance, because a low amount tends to produce a less stable polymer structure, wher…

Although Bank Syariah Indonesia (BSI) plays a strategic role in expanding Islamic financial inclusion in Indonesia, studies that specifically examine the effect of leadership differences on work motivation and work culture grounded in AKHLAK values within the Islamic banking environment remain limited. This study aims to analyze the influence of leadership style, work motivation, and AKHLAK value…

Early Childhood Education (ECE) constitutes an important foundation in shaping children’s cognitive, social, emotional, and moral development, so the quality of its services is largely determined by teacher performance as the main implementer of the learning process. However, in practice, the optimization of teacher performance still faces various constraints, such as discipline, creativity in th…

Mathematics learning at the elementary school level plays an important role in developing logical thinking skills and numeracy competencies. However, based on the results of observations at MI NU Rowolaku Kajen, the use of learning media remains very limited and has not utilized engaging media, resulting in low student interest in learning and affecting learning outcomes, particularly in the mate…

Xerosis, or dry skin, is a dermatological disorder characterized by a hydration deficit in the stratum corneum, resulting in a rough skin texture, a dull appearance, and reduced skin comfort. This condition is influenced by environmental exposure, high levels of daily activity, and suboptimal skin care practices. In the context of utilizing natural ingredients as safer and more accessible cosmeti…

Acne is one of the most common skin problems experienced by adolescents and adults and may reduce self-confidence. One natural ingredient with potential for use in acne skin care is binahong leaf extract (Anredera cordifolia), which is known to contain flavonoids and saponins that function as antibacterial and anti-inflammatory agents and help cleanse the skin of dirt and excess oil. This study a…

The increasing competition in beauty services in Padang City requires makeup artists (MUAs) to develop effective promotional strategies, one of which is personal branding on Instagram to attract consumer interest. This study aimed to analyze the effect of Instagram personal branding on consumers’ interest in using MUA makeup services in Padang City. The study employed a quantitative method with a…

Congo red is an azo dye widely used in the textile industry; however, its wastewater poses serious environmental problems because it is toxic to aquatic organisms, potentially carcinogenic, causes turbidity, and is difficult to degrade naturally. This study aimed to synthesize cobalt-doped ZnO nanoparticles with the addition of diethanolamine (DEA) as an additive to reduce the ZnO bandgap energy …

Although the use of instructional aids in Physical Education has been widely discussed, studies that specifically evaluate the effectiveness of traditional, local-wisdom–based instructional aids in enhancing elementary students’ participation and motor skills remain limited, particularly in Barru Regency. This study aimed to evaluate the effectiveness of traditional instructional aids in Physical…

The utilization of biomass as an alternative fuel is becoming increasingly important amid growing dependence on fossil energy and the abundance of plantation waste in Indonesia. Although briquettes made from palm kernel shells and coconut shells have been widely studied, research that specifically examines the effects of variations in material composition and carbonization temperature using tapio…

Although thermal conductivity test apparatuses have been widely used to characterize the heat transfer properties of materials, studies that specifically address the strength of their supporting frame structures remain limited. In testing practice, the frame of the apparatus is subjected not only to thermal loads but also to mechanical loads arising from the weight of components and clamping forc…

The successful synthesis of molecularly imprinted polymers (MIPs) is highly determined by the selection and ratio of functional monomers and cross-linkers, as these components directly affect adsorption capacity. The use of inappropriate types or ratios of functional monomers and cross-linkers can reduce adsorption capacity, either because quantities that are too low produce insufficiently stable…

Eco-enzyme is a fermentation product derived from organic materials that can potentially be produced from various biomass sources, yet the use of wild grasses on vacant land as a primary raw material has not been widely investigated.
