Abstract The results of this study found that the quality of nutmeg in South Aceh, namely climate type A with a very wet category, such as Alluvial, Brown Podzolic, Regusol, Grumosol, Organosol, Renzina, Litosol, Rock Outcrops, Podzolic, Rocks, Latosol and Red Yellow Podzolic. The chemical content of the soil, namely pH, N, P, K, C and CEC after analysis meets the criteria in determining quality nutmeg and soil texture that supports producing quality nutmeg oil processing, the dominant temperature is 26°C with dominant land slope <8% indicating South Aceh nutmeg plantations including a flat surface and the highest elevation is occupied by Meukek District with a height of 51 meters above sea level while the lowest is located in West Labuhan Haji District with an altitude of (-9) meters above sea level. The chemical content of nutmeg contains Myristicin with the highest levels being in North Kluet District, namely 41.08%, the lowest is in Tapak Tuan District, namely 16.66%, the highest chemical content of α-pinene is in Labuhan Haji Barat District, namely 7.85%. the lowest was in Tapak Tuan, namely 0.62%, the highest β-pinene was in Pasie Raja District, namely 14.24%, the lowest was in Meukek District, namely 0.56%.

Abstract This research aims to modify a vertical type patchouli waste chopping machine based on a structural and functional approach to the machine. The technical analysis used in this study was to the effective capacity of the machine, and the percentage of patchouli waste chopped. The results showed that the working capacity of the machine was greatest with a pulley size of 2.5 inches, the effectiveness of the engine performance was 2 kg/hour with a final weight of 0.5 kg, the time required was 0.25 hours. The rotational speed of the 2.5-inch pulley has an initial speed of 2,200 rpm and a final speed of 1,442 rpm, a 3-inch pulley has an initial speed of 2,200 rpm and a final speed of 1,171 rpm, and a 4-inch pulley has an initial speed of 2,200 rpm and a final speed of 856 rpm. The largest number of accommodated chopped results is in the 2.5-inch pulley size with an average yield percentage of 92%. The least percentage of stuck pieces is found in the 4-inch pulley with an average yield percentage of 17.8%. The smallest percentage of loss of pieces is found in the 2.5-inch pulley with a yield percentage of 0.4%.

This study assessed the ecological risk of urban landscape patterns, extracted and analyzed the remote sensing image information of the study area using RS technology, and determined the characteristics of the area's dynamic land use change. Then, using spatial analysis, overlay analysis, and spatial statistics in GIS, the landscape ecology statistics of the study area were conducted based on the annual land use changes in Xingtai City over the previous 20 years. The research shows that: (1) Land use change in Xingtai City from 2000 to 2020 indicates that farmland is the primary land source for urban expansion and development in the process of urbanization; (2) The degree of landscape fragmentation in the surrounding areas of cities and towns in the study area has decreased, and the degree of ecological risk in these areas has also been significantly reduced, reflecting that reasonable land planning can reduce the degree of ecological risk; (3) By analyzing the spatial distribution characteristics of landscape ecological risk, this paper identifies the crisscross zone of diverse ecological function areas as the region with the highest ecological risk.

Plastic pollution on land and in oceans is currently a pressing environmental issue. The accumulation of waste has caused severe, irreversible impacts and consequences on marine life, ecosystems, and the environment due to the lack of good waste collection, treatment, and management systems. Limited resources and infrastructure constantly challenge waste management in Southeast Asia. Therefore, we will examine the current plastic situation and issues in Southeast Asia and gain an understanding of the issues of the existing waste management systems in those countries. Then, we will examine the current practices applied in tackling plastic pollution and review the collective commitment and actions of governments, private sectors, social organizations, stakeholders, and consumers, as the key players in ending plastic pollution.

This article examines the roles of gender in the Bagang system, an organisation of the anchovy supply chain in Mempakad Laut, Sabah, Malaysia bordering the Marine Protected Area named Tun Mustapha Marine Park. Gender study on marine ecosystem management is important to understand the involvement of men and women specifically on how they are complementing each other in ensuring effective resource management. This exploratory study was obtained via qualitative approach as the data collections method including Focus Group Discussion (FGD), interviews as well as field observation. A total of 30 informants participated in this study which were selected through purposive sampling and snowball sampling method. Findings reveal that men and women are equally important in the Bagang system. Men work on marine affairs and material development, while women work on product processing and marketing. The contribution of women in the sustainability of the Bagang system was significantly visible and was treated equally in most aspects notably in financial management and in the decision-makings from the initial to the end of the anchovy supply chain. These findings are very important as guidelines to plan a better sustainable marine management for the future and a fine example of how sustainable fisheries can be achieved in supporting the United Nations Sustainable Development Goals No. 5 which is gender equality.

Abstract Productive paddy fields are an important asset in supporting food security. However, due to the increasing competition for land use with sectors outside agriculture, it has triggered the pace of land conversion without control and has the potential to threaten the stability of food supply itself. This study aims to identify the rate of paddy field conversion that occurs in Aceh Besar Regency, Aceh Province, Indonesia. This research was conducted through a spatial approach using the application of Geographic Information Systems (GIS) to identify forms of spatial change based on land use. The method used is a Supervised Classification. The results of the study showed that the highest rate of paddy field conversion occurred in the period 2010-2020 reaching 0.947%/year. This is not comparable to the ability of the substitution efforts made in the previous ten years (2000-2010) which was 0.88 %/year. The form of land conversion that occurred was dominated by the non-agricultural sector, especially residential needs reaching 61.89%. This has the opportunity to reduce rice production by 1,051.38 / year. Therefore, efforts to control the rate of land conversion are absolutely necessary to ensure sustainable food security.
