Panji Utomo, Adi Surjosatyo — Tue, 10 Dec 2024 00:00:00 +0000

The "Zero Waste City" program is a waste management policy initiative in Depok City that has been implemented from 2016 to 2024. The primary objective of this program is to make the entire Depok City area free from all types of waste. However, the program's implementation faces challenges, leading to some areas in Depok City still struggling with waste issues. Universitas Indonesia, as a higher education institution located in Depok City, acknowledges the waste-related challenges in its surrounding environment. Therefore, the university is committed to actively participating in solving waste issues originating from its campus environment. This research aims to address waste issues at the source, particularly by applying appropriate technology based on the criteria and sub-criteria at Universitas Indonesia. This step is expected to contribute to reducing waste-related problems in Depok City and serve as an example of effective waste management from its source. Notably, Universitas Indonesia contributes to the accumulation of residual waste at TPA Cipayugn Depok, which has become increasingly concerning over time. The analysis in this study employs the Analytical Hierarchy Process (AHP) and Fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) methods to evaluate suitable waste management technologies for addressing the issues of residual waste accumulation. Additionally, techno-economic analysis is conducted to assess the feasibility of the selected technology. The project's feasibility evaluation parameters include Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PBP), and Benefit Cost Ratio (BCR).

Cahyaning Rini Utami, Maftuhatuz Zakiyah Darojah, Deny Utomo — Fri, 20 Dec 2024 00:00:00 +0000

Phaseolus vulgaris L. are one of the plant-based food sources rich in nutrients and protein. Red beans contain protein (23.1%), carbohydrates (59.5%), calcium, phosphorus, iron, vitamin A, vitamin B1, and bioactive components such as flavonoids and phytosterols. Instant porridge is a complementary food for breastfeeding infants (known as MP-ASI) that is essential to meet the nutritional needs of babies during their growth phase. Red beans have the potential to be used as a raw material for making instant porridge as a complementary food for breastfeeding. Consuming red beans raw is not advisable, as they still contain several anti-nutritional compounds such as phytic acid, hemagglutinin, antitrypsin, and goitrogens that can hinder the digestion nutritional components. Therefore, a cooking process necessary to eliminate these anti-nutritional compounds, which can include soaking, boiling, and mold fermentation. The research design employed in this study is a literature review with a qualitative descriptive approach, utilizing content analysis methodology that references the analyzed journal manuscripts. Secondary data used in this literature review were obtained from previous research studies. The data sources utilized, namely articles and journals, were obtained from Google Scholar. The results of this literature review reveal the nutritional content present in instant red bean porridge and the potential of instant red bean porridge as a complementary food for breastfeeding. The nutritional content found in instant red bean porridge includes carbohydrates (49.95%), protein (18.79%), fiber (16.54%), and fat (1.20%). Furthermore, instant red bean porridge also contains various antioxidants such as flavonoids, tannins, saponins, triterpenoids, and coumarins.

Noorani Wafa, Fayaz Gul Mazloum Yar — Fri, 20 Dec 2024 00:00:00 +0000

Water resources are among the most vital natural elements and play a significant role in international relations, particularly for countries that rely heavily on these resources. This study examines the impact of water resource management on Afghanistan's international relations, particularly with neighboring countries such as Iran, Pakistan, and Tajikistan. As a landlocked nation, Afghanistan relies heavily on its water resources, which are crucial to its political, economic, and social stability. Mismanagement and unsustainable use of these shared resources can lead to international tensions, social unrest, and environmental degradation. Using both qualitative and quantitative methods, the research analyzes the opportunities and challenges associated with water resource management. It emphasizes the need for international cooperation, legal frameworks, and modern technologies. The findings suggest that effective water resource management can foster regional cooperation and improve Afghanistan's socio-economic conditions, while inadequate policies may heighten tensions. The study offers strategic recommendations to address these challenges and promote sustainable development.

Exploration of Work Accident Prevention Behavior Among Technical Service Personnel In the Implementation of The 'One Pict Saves You' Movement at PT PLN (Persero) Customer Service Unit Bireuen

Ricky Gunawan, Bobby W. Saputra — Fri, 20 Dec 2024 00:00:00 +0000

This study aims to explore the work accident prevention behaviors of technical service officers in response to the implementation of the "One Pict Saves You" initiative at PT PLN (Persero) Customer Service Unit in Bireuen. This initiative was introduced to improve compliance with the use of personal protective equipment (PPE) as a preventive measure to reduce workplace accidents. The methodology used in this study is a qualitative approach with thematic analysis techniques. Data was obtained through in-depth interviews with supervisors, management, and technical service officers, as well as an analysis of the company's safety documents. Interview questions focused on officers' awareness of the importance of PPE, compliance with safety procedures, and behavioral changes following the implementation of the "One Pict Saves You" initiative. The results indicate that the implementation of this initiative successfully increased awareness and compliance with PPE use. Most officers recognized the importance of PPE in protecting their own safety and felt encouraged by consistent visual monitoring. Additionally, the data demonstrated positive changes in safety behavior, including voluntary compliance and enhanced awareness of safety procedures. However, challenges remain in overcoming factors that inhibit consistent compliance, such as occasional PPE availability issues and ingrained habits. The managerial implications of this research highlight the importance of developing an app-based monitoring system, improving internal communication regarding safety procedures, and providing incentives for officers who comply with safety protocols. The company is advised to continue periodic safety training and awareness programs to ensure that behavioral changes remain sustainable.

Conceptual Cost Estimation In Green Buildings By Using Regression Analysis And Artificial Neural Network Methods To Improve Accuracy

Wisnu Isvara, Fauziyah Kamilah — Fri, 20 Dec 2024 00:00:00 +0000

Conceptual cost estimation is a critical task during the early stages of a construction project, especially for green buildings, which present unique sustainability challenges and design complexities. Traditional methods such as regression analysis are widely used but often rely on experienced estimators and are time-consuming, while Artificial Neural Networks (ANN) offer a modern alternative but are limited by the quality and quantity of available data. This study aims to develop a hybrid model combining regression analysis and ANN to improve the accuracy of conceptual cost estimation for green and conventional high-rise buildings in Indonesia. Using data from 22 high-rise building projects (13 conventional and 9 green buildings), the study employed regression analysis, ANN techniques, and a combination of the two, with eight key variables selected for modeling. The hybrid model demonstrated the highest accuracy, achieving a Mean Absolute Percentage Error (MAPE) of 15.09%, within the acceptable range for conceptual cost estimation (+10–30%) as per AACE standards, outperforming standalone regression and ANN models. These findings highlight that integrating regression analysis and ANN provides a robust tool for early-stage cost estimation, supporting sustainable construction practices and informed decision-making.
