Abstract

Penelitian ini bertujuan untuk menguji pengaruh intensitas pemanfaatan Generative Artificial Intelligence (GenAI) terhadap kemampuan berpikir kritis mahasiswa, dengan literasi digital sebagai variabel moderasi. Sampel penelitian terdiri dari 40 mahasiswa S1 Desain Produk Industri di Sekolah Tinggi Teknik Multimedia International Malang. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan analisis regresi hierarkis. Hasil penelitian menunjukkan bahwa intensitas pemanfaatan GenAI memiliki pengaruh positif dan signifikan terhadap kemampuan berpikir kritis (?=0.473;p<0.01). Temuan kunci dari penelitian ini adalah bahwa literasi digital secara signifikan memoderasi hubungan tersebut (?interaksi?=0.268;p<0.05). Ini mengindikasikan bahwa dampak positif penggunaan GenAI pada berpikir kritis lebih kuat pada mahasiswa yang memiliki literasi digital tinggi. Sebaliknya, efek positif ini menjadi lebih lemah pada mahasiswa dengan literasi digital rendah. Implikasi dari penelitian ini menunjukkan bahwa GenAI dapat menjadi alat yang efektif untuk mengembangkan keterampilan berpikir kritis, namun manfaatnya sangat bergantung pada kompetensi digital pengguna. Oleh karena itu, diperlukan penguatan kurikulum literasi digital di perguruan tinggi untuk memastikan mahasiswa dapat memanfaatkan GenAI secara kritis dan produktif.

Abstract

Purpose: This study aims to analyse and develop design a heat exchanger (HE) for the production of Methyl Ethyl Ketone (MEK) which will be compiled into a computational program for the design of shell-tube type HE. Methodology: The problem with this HE is that the temperature of 2-butanol is 30?C from the storage tank. While the HE reactor requires a temperature of 99.6?C, HE plays a role in increasing the temperature from 30?C to 99.6?C. To be more energy efficient, researchers used heat of the product, MEK. Which is where to exchange heat from the product to the reactants. The design of a shell-tube two-pass exchanger with a working fluid in the form of 2-butanol as a hot fluid with water as a cold fluid. Results: Thus, HE with shell and tube doesn’t meet the requirements and standards of TEMA. Although the shell and tube type of HE doesn’t conform to the criteria and standards specified in industrial applications, the analysis can be used as a learning tool for the design process, heme performance analysis, and operating mechanism of the HE. Limitations: This research is focused on developing HE designs for the production of MEK. Contribution: This research can provide a reference for designing HE in industrial development. Conclusion: The designed shell-and-tube heat exchanger shows limited efficiency and does not comply with TEMA industrial standards. However, the study provides valuable insights into the design methodology and serves as a foundation for further optimization of heat exchanger systems to enhance performance, efficiency, and industrial applicability.

Abstract

Increasing demand on olefins, high energy consumption of thermal cracking and oil depletion are the driving force to find new process to produce olefins. Catalytic cracking of n-butane is promising route to produce olefins. In this paper, we synthesized nanoparticle from natural zeolites by ball milling-recrystallization method and studied the effect of acid dealumination over the nanozeolites on the catalytic properties. Particle size was evaluated visually by using scanning electron microscope. X-Ray Diffraction analysis was performed to study zeolites phase and its crystallinity. Acid dealumination effect over nanosized mordenite on the acidity were evaluated by ammonia TPD and pyridine FTIR. Textural properties of zeolites were characterized by nitrogen physisorption at -196 oC. The catalysts were tested in a fixed bed reactor for n-butane cracking to olefins product. Various temperature conditions were applied ranging from 350 oC to 650 oC for n-butane cracking in a fixed bed reactor. Conversions of n-butane were 15% and 90% at 350 oC and 650 oC, respectively. Selectivity to olefins was increase from 1% at 350 oC to 47% at 650 oC.

Abstract

In Indonesia, tapioca wastewater is one of the most abundant organic wastewater. It has a great deal of potential for use as a substrate for biogas, but it contains a high ratio of chemical oxygen demand (COD) to nitrogen (N). For this reason, adding nitrogen sources, such as urea, is crucial. Meanwhile, microbial electrolysis cell-assisted anaerobic digestion (MEC-AD) is a novel technology that can be applied to enhance biogas production. Thus, the purpose of this study was to ascertain how adding urea affected the biogas yield from tapioca wastewater through the MEC-AD process. There were six digesters, namely A (MEC-AD urea 0.25 g), B (MEC-AD urea 0.5 g), C (MEC-AD urea 1 g), D (MEC-AD urea 1.5 g), E (MEC-AD without urea), F (AD without urea). The MEC-AD process was carried out at room temperature using a batch system. The results revealed that the MEC-AD (without urea) generated a biogas yield 2.3-fold higher than AD alone (without urea). Then, an increase in urea addition in the MEC-AD process from 0 to 1.5 g enhanced biogas yield from 106.4 to 268.8 mL/g-COD. It means that in MEC-AD, the urea addition of 1.5 g generated 2.5 times more biogas yield than without urea addition. The MEC-AD with urea addition of 1.5 g had the most stable substrate pH and the highest volatile fatty acids during the process. The MEC-AD (without urea) gave a higher COD removal efficiency (21%) than AD alone (without urea), namely 14%. Then, an increase in urea addition from 0 to 1.5 g in MEC-AD increased COD removal from 21% to 38%. Therefore, the best variable was MEC-AD with a urea addition of 1.5 g. This innovation is expected to reduce environmental pollution and provide biogas as alternative energy to substitute the use of fossil fuels.

Abstract

Achieving the Sustainable Development Goals (SDGs) requires effective multi-stakeholder collaboration and localization of global targets into local development planning. This study investigates how collaborative governance is applied in the formulation and implementation of the Regional Action Plan (RAD) for SDGs in DKI Jakarta, Indonesia. Using a qualitative descriptive approach and the Collaborative Governance Regime (CGR) framework by Emerson and Nabatchi, this research combines a systematic literature review (SLR) of 22 international and national studies with empirical data from in-depth interviews and document analysis. The findings reveal that while Jakarta has formally adopted collaborative principles in its RAD SDGs process, key challenges persist in inclusivity, trust-building, and resource mobilization—especially among non-governmental stakeholders. Many engagements remain consultative rather than deliberative, and joint action capacity is limited by structural and procedural gaps. This article contributes to the emerging literature on localizing SDGs by highlighting the gaps between normative collaborative ideals and practical implementation at the local government level. It also offers policy insights on strengthening stakeholder roles, institutional arrangements, and collaborative mechanisms to improve the effectiveness of SDG governance at the sub-national scale.
