Most bridges in Indonesia are not in good condition, and the number of collapsed national bridges is relatively high. In addition to poor maintenance, construction-related accidents during bridge projects are also frequently reported. Therefore, a system such as the Structural Health Monitoring System...

In the hospitality industry, feedback reviews play a vital role in shaping perceptions and influencing decision-making. These reviews are not only valuable for stakeholders but also serve as important information resources, for instance, to improve customer satisfaction. However, the large volume of...

Accessing data from modern cloud databases remains a significant challenge for users without expertise in Structured Query Language (SQL), creating a bottleneck in data-driven decision-making. This paper introduces Querier, a system that bridges this gap by leveraging a Large Language Model (LLM), specifically...

The increasing global population has led to a growing demand for clean water, accelerating the development of innovative, electricity-free purification systems for remote areas. A promising solution is a solar-driven water purification system that utilizes thermoresponsive hydrogels to adsorb and desorb...

Today, most of the nanocrystals researched for use in electronic devices, such as solar cells and photodetectors, worldwide include toxic metal elements (Pb, Cd, or Hg) or scarce elements. To replace them with eco-friendly compounds, it is necessary to understand their electronic and optical properties...

The application of additive manufacturing (AM) techniques is crucial to developing the industrial sector. This method is demonstrated by the use of wire-based methods to achieve effective and efficient production results. Wire arc additive manufacturing (WAAM) is a type of additive manufacturing process...

Wire Arc Additive Manufacturing is a Direct Energy Deposition process that uses an electric arc as the heat source to melt metal wire layer by layer. WAAM-based additive manufacturing presents one of its main challenges: material deformation caused by thermal effects during the welding process. In this...

Gluconic and xylonic acids are increasingly recognized as valuable bio-based chemical building blocks due to their broad applications in food, pharmaceutical, and polymer industries. These organic acids are primarily derived from the oxidation of glucose and xylose, respectively those two major monosaccharides...

This study investigates tuna (Euthynnus affinis) bone by-products as an alternative collagen source to meet Indonesia’s rising demand. Process simulations in SuperPro Designer evaluated two extraction routes: (i) Natural Deep Eutectic Solvents (NaDES) and (ii) bromelain enzyme. Using 337,219 kg raw material...

Chromium (Cr) is a heavy metal widely used in various industries. Chromium (Cr), a heavy metal, has significant risks to human health and the environment. Chromium in the hexavalent form (Cr VI) is more hazardous than chromium in the trivalent form (Cr III). This work investigated the performance of...

Small and Medium Enterprises (SMEs) are one of the main support of the economy in Indonesia. One way to increase competitiveness of SMEs is through appropriate performance measurement methods (PMM). This research take a case study in SMEs Machinery Industry, because SMEs Machinery Industry which is the...

Patients with type 2 diabetes mellitus (T2DM) tend to experience worse clinical outcomes when infected with SARS-CoV-2. The hyperinflammatory state associated with diabetes contributes to immune dysregulation during COVID-19 infection, often triggering a cytokine storm that exacerbates disease severity....

The exploration of microorganisms from extreme environments in Indonesia remains limited, despite the country’s richness in diverse and unique ecosystems. This study aimed to investigate the bacterial community diversity in a highly acidic sulfur mud pool in Kragilan, Banten, using the Oxford Nanopore...

This study investigates the impact of varying concentrations of zinc acetate dihydrate on the morphological and surface properties of electrospun polyvinyl alcohol (PVA) fiber layers applied to magnesium substrates, intended for use as a biodegradable implant material. Electrospinning was employed to...

Uncontrolled bleeding (hemorrhage) remains a critical concern in trauma and surgical settings, often leading to multi-organ failure and mortality. Gelatin-based sponges are widely used as hemostatic agents due to their excellent biocompatibility and fluid absorption capabilities. However, their functionality...

Exosomes derived from mesenchymal stem cells (MSCs) have emerged as promising candidates in regenerative medicine due to their immunomodulatory properties.
