Belawan Port is one of the main ports in Indonesia whose role and function are important in the national logistics system. Belawan Port is a gateway for the Province of North Sumatra. The port must have sustainability in carrying out its role and function as transportation and economic infrastructure. In this research, Belawan Port sustainability will be evaluated from several aspects or dimensions, namely ecology, economy, social culture, technology, and institutions and law. Belawan port sustainability analysis using the Multidimensional Scaling method, using the modified Rapfish program. The analysis is carried out on five dimensions and 49 attributes/factors, which are used as a reference in the SDGs program. Not every SDG will be relevant for every business, however, every SDG should be considered. SDGs no.4 and no.5 are not directly related to port management activities, while SDGs no.8,9,11,14,17 are directly related. From the analysis obtained Ecology sustainability index = 48.38 (less-sustainable), Economic sustainability index = 42.89 (Less-Sustainable), Socio-Cultural sustainability index = 52.47 (Fair-Sustainable), Technological sustainability index = 54.11 (Fair-Sustainable), Institutional and Legal sustainability index = 50.74 (Fair-Sustainable). With policy and program interventions, the sustainability of the existing Belawan Port in the short term can be improved to be fair-sustainable for all dimensions (ecology, economy, social & culture, Technology, Institution & Law) evaluated. © Published under licence by IOP Publishing Ltd.

The objective of this study is to explore the strengths of indigenous food systems in Latin America within the framework of effective food policies. The analysis is based on the adaptive ca-pacity of human beings, and, in this logic, it considers the food systems of Latin America to be rele-vant since in the face of challenges, such as climate change and the COVID-19 pandemic, indigenous peoples have been able to establish response strategies. However, beyond these responses, we find a region that has assumed a biopolitical stance with a tendency to design control policies in response to the pandemic. This situation has not improved the inequalities and vulnerabilities of a sector of the indigenous population in Latin America. The aforementioned challenges give a clear picture of the strengths of the region's indigenous people, and knowledge of this interactive dynamic can pro-vide elements for the design of food policies. In this sense, an exhaustive literature review was car-ried out in order to approach the state of the art of the issue. The analysis was derived from three analytical categories that in synergy and from an open innovation perspective, make a proposal for the design and implementation of effective food policies that allow a region to learn from local indigenous experiences in a context of food insecurity. © 2022 by the author.

This paper presents the first nationwide analysis detailing the scope and scale of labor-intensive forestry contracts performed on National Forest System lands and examines the businesses contracted, location and types of work performed, and distance traveled by businesses between 2001 and 2020. During the study period, 61,698 contracts were awarded to 7,896 businesses, totaling $12.9 billion, to perform labor-intensive forestry work, with most work being contracted for wildfire-related activities. Businesses were typically located in western states and non-minority owned businesses received the majority of contracts. Of minority-owned businesses, Hispanic American–owned businesses received the most contracts. The median distance that businesses traveled to accomplish work increased significantly through time but differed by business type. Understanding the scope and work of businesses awarded contracts provides insight into the workforce and its relationship to marginalized populations. Strategic investment in this workforce may have widespread impacts on federal, state, and local economies and the livelihoods of forest *** Implications: Between 2001–2020, the USDA Forest Service spent billions of dollars on contracts with thousands of businesses to conduct labor-intensive forestry projects; however, project locations and awarded businesses were not evenly distributed through space and time. Emerging and minority businesses represented a small proportion of contracts awarded. Advancing understanding of the businesses conducting labor-intensive forestry work lays the foundation for inquiry into the working conditions forest workers experience as well as disparities in contract capture. Some regions may have benefitted more from contract capture than others. Understanding factors enabling places and businesses to capture these contract dollars may help identify others that may benefit from investment.

Groundwater quality assessment is critical for sustainable water resource management, especially in hyperarid regions like Adrar, Algeria, where data scarcity and environmental challenges hinder traditional monitoring methods. This study explores the application of three Few-Shot Learning (FSL) algorithms: Prototypical Networks, Siamese Networks, and Matching Networks, for groundwater quality classification using limited datasets. The dataset comprises 166 groundwater samples from the Adrar region, characterized by five quality classes: “Excellent,” “Very Good,” “Good,” “Satisfactory,” and “Unsatisfactory.” Results demonstrate that Prototypical Networks outperform other FSL algorithms, achieving 93 % accuracy with 10 support samples per class, while Siamese and Matching Networks achieve 90 % and 88 % accuracy, respectively. The study highlights the potential of FSL in addressing data scarcity, offering a cost-effective and efficient approach for groundwater quality assessment in data-scarce regions. The findings underscore the importance of FSL in complementing traditional methods, particularly in hyper arid areas where data collection is challenging.

Marker-less motion capture has been extensively studied in recent years as a means of evaluating productivity, safety, and workplace design for manual operations on-site. These technologies are ideal for circumstances in which traditional motion capture systems are ineffective due to the need for a laboratory setting and movement-inhibiting markers or sensors. However, many marker-less motion capture systems rely on RGB-D sensors that have limited range and susceptibility to interference from sunlight and ferromagnetic radiation, making them unsuitable for modeling worker actions on construction sites. To address this issue, we propose a marker-less motion capture approach utilizing optical images and depth data obtained from stereo vision cameras. Multiple camera lenses and triangulation algorithms generate depths maps similar to those produced by RGB-D sensors, while still utilizing an optical recording process unhindered by potentially harsh construction site conditions. These data are adapted for existing kinematic modeling systems (i.e. iPiMocap Studio) for 3-D pose estimation. The experiments show that the proposed approach can provide data precision comparable to that of RGB-D-based systems with fewer operational constraints;thus, motion data can be collected where previously developed methods fail due to environmental or maneuverability restrictions. With the proposed approach, kinematic modeling of human movements can be carried out on construction sites without inhibiting the mobility of the recorded subject. © ASCE 2014.

The aims of the study were to investigate characteristics of activated carbon prepared from banana peels as adsorbent for the removal gasesemission from motorcycles. The effect of differents chemocalactivators and contact time were studied on the characteristics of banana peels raw carbon (RC) and chemically activated carbon (CAC) such as moisture content, ash content, volatile matter. The best ofIodine adsorption capacity of CAC H2SO4 3N 3 hour contact, was obtained at 913,68 mg/g adsorbent. Structure and morphology ofRC and CAC were characterized by Fourier transform infrared (FTIR) and field emission scanning electron microscopy (SEM). The results showed that RC and CAC could significantly adsorbed the CO and SO2gasesemissions from motorcycles, but not applicable for NO, NOx gases. After 10 minutes analysis using gas emission Analyzer, CO gas could be removed, from initial 16014 ppm to 3578 ppm using CAC H2SO4 adsorbent, while SO2 gas could also be partly removed from 217 ppm to 19 ppm using CAC ZnCl2 *** peels carbon produced was suitable for application in removing CO and SO2gases emissions from motorcycles and it helps to reduce the green house gas effects of fossil fuel usage to the environment. © Published under licence by IOP Publishing Ltd.

The process of continuous landfill in the area of the final disposal (landfill) of waste produces pollutants such as leachate (leachate) is a liquid containing dissolved substances and suspended very fine as a result of waste decomposition by microbes. Leachate water contains decomposing organic materials and heavy metal materials. Heavy metals (Cr, Hg, Pb, Cu, Fe, Mn, Zl, Cl) present in leachate water are from waste that has been disposed to TPA Keudah Kota Banda Aceh. The author would like to do research on the adsorption of heavy metals by using Atomic Absorption Spectrophotometer in landfill leachate Banda Aceh. The purpose of this research is to get the absorption of some heavy metals in the landfill leachate by using AAS analysis method. The results of the analysis in landfill leachate solution Banda Aceh by using Atomic Adsorption Spectrohotometer its highest uptake in heavy metal parameters Iron (Fe) amounted to 10.9191 ppm, and is followed by the parameters of heavy metals (Ni) 0.9820 ppm, ( Zn) 0.4188 ppm, (Co) 0.1698, (Cu) 0.1198 ppm, (Pb) 0.0602 ppm, (Cr) 0.0502 ppm, (Hg), and (Cu) Cd) the results are not detected (ND). Considering that Indonesia in the future is still faced with environmental pollution problem as a result of the development, the restoration and rehabilitation of contaminated land needs to get mutual attention, such as by using dilution method, stabilization, and phytoremdiation technique. © Published under licence by IOP Publishing Ltd.

Municipalities all over the globe seek to evaluate the sustainability of their communities and this process requires an interdisciplinary perspective. Walkability and social capital are important measures of sustainable communities that are not necessarily considered together in measurement schemes. Through a community-based case study, the following article examines the relationship between select measures of social capital and self-perceived walkability. Descriptive statistics demonstrated that higher levels of social capital existed in more walkable communities. More sophisticated analysis further supported this association. A community index was created from responses to questions about participating in civic engagement activities such as donating blood, attending a committee meeting or public hearing, interacting with individuals in various neighborhoods, and contributing to a community project. A trust index was also created with answers to survey questions about general trust and trust of neighbors and other members of communities. Multilevel models demonstrated that higher levels of walkability were associated with higher levels of participation in community activities, even after controlling for socio-demographic factors. Similar patterns were found for the trust index where higher levels of walkability were positively associated with positive responses to a variety of trust questions. Implications for sustainable communities policy and management are suggested. © 2012 AESS.
