Nurbia Nurbia, Samsuddin Affandi — Fri, 01 Mar 2024 16:38:33 +0700

The Klagison River is one of the rivers located in the North Sorong District to the Sorong Manoi District. The flow of the Klagison River is used by the sand mining industry to dispose of liquid waste products from mining sites. Mining activities are in the middle of the Klagison River so that it can affect the quality of river water and experience a decrease in carrying capacity due to the high level of turbidity in river water caused by sedimentation. The purpose of this research is to provide knowledge about the content of metal elements in sediments by identifying the constituent elements of the Klagison River sediments, Sorong City, West Papua. Determination of the sampling point using the purposive sampling method and the sediment collection tool using the Ekman grab. The method of analyzing the constituent elements of the sediment uses the XRF (X-Ray Fluorescence) method. Based on the research results, there are various types of metal elements contained in the sediments of the Klagison River, namely the elements Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Zr and Re where the dominant concentration of metal elements from 5 observation stations is Fe>Si>K>Cl>Al>Ca. At the 5 observation stations, the element Fe>Si>K>Cl>Al>Ca was the highest compared to the other 4 observation stations. This is because station 5 is the mouth of the Klagison River so that it becomes a place for liquid waste deposits to coalesce.

Elham Elham, Syamsul Maarif, Syaiful Anwar, Rina Mardiana — Thu, 25 Jan 2024 00:00:00 +0700

The government neglects to pay attention to village development as a result of the inaccurate data collected by numerous entities. Whereas in reality, there are many people who currently hold land tenure that might be used to grow into a community that is sustainable. This study therefore intends to evaluate the Indonesian Big Agrarian Data (IBAD) implementation paradigm based on sustainable villages. The study was carried out in the West Nusa Tenggara village of Senawang in the Orongtelu District of Sumbawa Regency. Six months were spent conducting the research. The information used is a combination of primary data from questionnaire and secondary data from earlier studies or library searches. The ISM analysis approach was employed to develop a sustainable village implementation model. The findings indicate that proper implementation can impact the community, BPN/ATR, and BIG by utilizing licensed surveyors and focusing on policy interpretation from the Coordinating Ministry for the Economy. However, there is no complete data survey and map method, and a data guardian has not been established. Therefore, adjustments are necessary to develop comprehensive village measurement policies and change employee perspectives.

Behavioral Intention of Domestic Organic Waste Segregation in Urban Communities (Case Study: Sukmajaya and Cilodong Districts, Depok City)

Rohana Carolyne Putri, Mahawan Karuniasa, Sri Wahyono — Fri, 01 Mar 2024 00:00:00 +0700

Waste management is a significant and widespread issue that challenges many countries, particularly developing countries. Organic waste is a primary contributor to greenhouse gas (GHG) emissions in waste management, making it a crucial problem to address. Proper waste management practices, including decentralized organic waste management, are necessary to address this issue. However, this decentralization requires the support of the community’s waste segregation behavior. Therefore, this study was conducted in Sukmajaya and Cilodong Districts to analyze the intention of organic waste sorting behavior utilizing Theory of Planned Behavior (TPB) analysis. The results showed that only two constructs, attitude and perceived behavioral control, positively impacted the intention to sort organic waste. In this study, norm construction does not serve as a supporting construction for the waste sorting intention. Additionally, knowledge of waste sorting programs and activities significantly affects perceived behavioral control.

Iswandi Umar, Triyatno — Fri, 01 Mar 2024 00:00:00 +0700

Floods are the most common natural disasters in Indonesia and have enormous potential. This study aims to determine the flood hazard zone and regional arrangement in the Tarusan Watershed, South Pesisir Regency. To determine the flood hazard zone using the GIS approach. The indicators used to determine flood hazard are slope, rainfall, soil type, landform, geology, and land use. Determine the direction of regional arrangement with an Interpretative Structural Modeling (ISM) approach. The results showed that the high flood hazard zone in the Tarusan watershed is about 22% of the total area, the medium index is around 58%, and the low flood hazard index is 20%. The high - hazard zone of flood disasters in the study area is caused by high rainfall and topographic conditions of the Tarusan Watershed. The main priority in the management of flood - hazard areas in the Tarusan Watershed is to find economic alternatives to reduce forest destruction. Increasing the economic value of the community can lead to reduced community activities in carrying out land conversion, especially in forest areas.

Salma Khairunnisa, Prijanto Pamoengkas, Adisti Permatasari Putri Hartoyo — Sat, 16 Mar 2024 12:13:25 +0700

Mount Halimun Salak National Park (MHSNP) traditional zone is a zone which is highly utilized by the local community to fulfill their daily needs by utilizing non-timber forest resources and implementing an agroforestry system with the main commodity is poh-pohan (Pilea melastomoides). Forest monitoring in the MHSNP traditional zone is very important to do as part of sustainable forest management and the realization of supporting Indonesia's Forestry And Other Land Use (FOLU) Net Sink 2030 program. This study aims to analyze the density of vegetation based on NDVI values; besides, analyze the level of plant species diversity and stand structure in the traditional zone of MHSNP. Furthermore, the data collection of plant species diversity at the area based on NDVI value of vegetation density. NDVI values are obtained into three classes that have different land conditions. The class 1 value range from 0.147 to 0.273 has a low vegetation density. Class 2 from 0.273 to 0.319 has medium vegetation density. Meanwhile, class 3 has high vegetation density with a value of 0.319 to 0.433. Diversity of plant species has 60 different species from a total of three classes. The density of seedlings is lower than saplings and at the level of poles, trees is decreasing that is indicates a balanced stand structure. The low seedling level is caused by inhibition of seedling growth due to cleaning by the local community in preparation for planting understory since the community prefers to plant understory which harvest faster woody plant seedling.

Microplastics in the Central Citarum River, Karawang, West Java, originate from anthropogenic activities of people living around the watershed, which is an industrial, agricultural, and densely populated residential area. Microplastics are degraded plastics < 5 mm in size. This study aims to determine the abundance and size of microplastics in the Middle Citarum River, through observation with a microscope. Sampling was conducted at three locations with three observations: February, March, and April 2022. The types of microplastics found were pellets, films, fibers, and fragments. Microplastic particle size < 0.3 mm was the most common size found. The abundance of microplastics in the water of the Middle section of the Citarum River is different at each sampling location. The total number of microplastic particles in all research locations was 4,413 particles. The highest abundance of microplastics in all sampling locations was in densely populated residential areas at 239.7 ± 326.7 particles/m3 , followed by agricultural areas with an abundance of 72.5 ± 63.8 particles/m3 , then the lowest abundance was in industrial areas at 55.6 ± 57.8 particles/m3
. The average abundance of microplastics in the middle Citarum River water was 122.6 ± 209.7 particles/m3. Statistical analysis using Kruskall Wallis with a df value of 2 > 0.05 showed no significant difference in microplastic abundance at each research location. All stations had the same potential for microplastic pollution. This study shows that high anthropogenic activities lead to high microplastic pollution in water. Therefore, proper mitigation and management of waste and plastic waste are needed.

The shrimp nursery infrastructure consists of nursery tanks, mechanical filters, biological filters, and ultraviolet (UV) filters. This study aimed to simulate the water level elevation (head) of shrimp nursery infrastructure, especially nursery tanks. The placement of the nursery greatly affects the elevation of the water table owing to the loss of energy (headloss) that occurs in the flow. The nursery tub used in this study was round and consisted of four tubs made of fiber resin measuring 250 cm in diameter and 120 cm in height. The bottom of the tub was placed at an elevation of +40 cm above the ground. The simulation was conducted for 24 hours. The results of the EPANET 2.2 simulation showed head fluctuations in each nursery with the highest elevation (1.38 m and the lowest (1.20 m, from the data. The head fluctuated constantly after 6 h of the flow. The optimal pipe diameters were 3" (80 mm) PVC and 4" (110 mm) PVC.

Savira Pramesti Ramadhani, Leti Sundawati, Budi Kuncahyo — Sat, 23 Mar 2024 09:53:17 +0700

The success of sustainable forest management is inseparable from community participation as the leading actor in the Social Forestry Program. Various factors, including internal factors from the community and external factors, affect the participation of the community. Factors impacting community participation in sustainable forest management were analyzed in this study. The study was conducted at BKPH Mojorayung, KPH Madiun, East Java Regional Division Perum Perhutani, from April to June 2022, using a survey method with 242 randomly selected respondents. Partial Least Squares (PLS) analysis was conducted with the SmartPLS software. Based on the results, it was found that three factors impact the community's participation in forest management: the empowerment process accuracy, the role of community empowerment workers, and the support of group leaders. The characteristics of the communities around the forest did not affect community participation in forest management. Community participation also affects the sustainability of forests.

The Utilization Contestation of Indonesian Inland Waters (Case: Lebak Lebung dan Sungai (L3S) Auction in Ogan Komering Ilir District, South Sumatera)

Fevi Rahma Dwi Putri, Arif Satria, Rillus A Kinseng, Taryono — Sat, 23 Mar 2024 09:55:59 +0700

Some of the Lebak Lebung and river public water areas in South Sumatra are governed by an auction system that has been carried out for a long time by the local community based on clans, namely "Lelang Lebak Lebung dan Sungai" (L3S). After 1982, the authorities implemented an auction system that transferred the implementation of the auction system to the management regime of the district government to apply regional autonomy. This transition provided governance changes, especially for the increasingly complex actors involved and competing in the L3S battle arena. This article aimed to analyze actor battles in the L3S arena by analyzing specifics about the regime transition change before and after the management of L3S applied, the institutionalization of patronage that was formed, and the social conflicts that occurred. This study used a constructivist paradigm and qualitative research methods. We identified 39 informants as research subjects who were chosen deliberately and analyzed the data using three stages: data reduction, presentation, and conclusion. The study results show that changes in L3S management are dominated by changes in rules and authority holders, which encourage access domination by entrepreneurs/non-fishermen. New working relations are formed by placing local fishermen as laborers and new non-fishermen actors as buyers. As a result, conflicts have occurred between actors.

Nita Aribah Hanif, Eko Priyono Utomo, Rahmawati Husein — Sat, 23 Mar 2024 09:58:18 +0700

This study aims to compare the efforts of the Governments of Indonesia and Denmark in realizing a smart environment SDG's agenda. This urgency is motivated by the poor environmental conditions in Indonesia while the government is targeting a reduction in emission production by 2030. This research uses a qualitative method. The results of this study indicate that the Government of Indonesia in pursuing a smart environment has not been optimal. This can be seen from the several indicators used in this study: (1) the Attraction of Natural Conditions indicator, the Indonesian Government has not enforced regulations or programs aimed at maintaining the balance of green open spaces. Meanwhile, the Danish Government has launched a city greening program through construction of green buildings. (2) Air Pollution Integrated Index indicator, the Indonesian government has not been able to minimize the number of vehicles through the use of electromobility-based vehicles as has been done by the Danish government. (3) Indicators of Sustainable resource management, the Indonesian Government has not been able to optimize the development of technology for processing waste and waste into residues that can be reused. While in Denmark, which is able to turn waste into residue that can be reused.

Heri Ariadi, Benny Diah Madusari, Dewi Mardhiyana — Fri, 29 Mar 2024 09:40:39 +0700

Coastal areas are considered biodiversity zones. This study aimed to analyze the effectiveness of land use on aquaculture productivity rate in coastal areas using a dynamic modeling analysis system. This study was conducted in the Pekalongan Province. Water quality parameters and qualitative research data were obtained from an in-depth survey. Furthermore, the data were analyzed using dynamic modeling analysis. The results of this study indicate that the level of coastal land use has a variable relationship with the productivity rate of aquaculture. Based on the causal loop model, it could be analyzed that the social, environmental conditions in coastal areas were described as continuing to experience quantification of population increase and environmental utilization rates. Overall, the productivity level of aquaculture cultivation in coastal areas tended to decrease along with the increasing value of productive land use accompanied by increased inputs and the number of human resource populations in coastal areas. The optimal inclusion of this study was that the optimal land use level would impact the productivity management level of aquaculture cultivation in coastal areas. Based on the results of this study, it can be concluded that the optimal utilization of coastal land greatly impacted the management of the productivity level of aquaculture cultivation, which was carried out in an integrated manner. Furthermore, the analysis of the dynamic modeling system also illustrated the increasing social-environmental conditions in coastal land utilization.

Anjar Krisnanta, Hayati Sari Hasibuan, Rudi Parluhutan Tambunan — Fri, 29 Mar 2024 09:44:17 +0700

North Coastal Central Java has been a strategic zone from the colonial era to the present because it supports the national socio-economic sector. Urbanization has threatened the development of districts/cities on the northern coast of Central Java. The physiographical conditions of coastal districts/cities along Pantura are formed from alluvial plains, making the environment's carrying capacity more vulnerable to changes in global conditions and pressures from the socio-economic activities of the population. This study aims to identify changes in land cover, its relationship to road infrastructure development, and its implications for environmental carrying capacity. The method used in this study uses GIS to determine changes in land cover and settlement growth patterns and calculates biocapacity and ecological footprint to obtain environmental carrying capacity conditions. The results show that land cover changes mainly occur in agricultural land, plantations, and settlements. In addition, the environment's carrying capacity experienced a deficit/overshoot in 2010, which continued until 2020. The result indicates the problem in the environmental dimension of sustainable development of coastal cities and requires serious intervention to increase environmental quality.

Carbon Sequestration in the Green Open Spaces along Primary Road of Pontianak City, West Kalimantan, Indonesia`

Fri, 29 Mar 2024 09:53:24 +0700

Global climate change caused by greenhouse gas (GHG) emissions is currently a focus for various countries worldwide, including Indonesia. Carbon dioxide (CO2) is the main source of emissions, with a significant portion originating in urban areas. This is due to the high levels of air pollution from motor vehicles and rapid industrial growth. Urban green spaces are areas within cities that consist of non-built-up spaces filled with naturally grown or cultivated vegetation. These green spaces exist directly alongside the transportation infrastructure, which helps reduce air pollution, especially CO2, through the vegetation that makes up these areas. One type of urban green space is a green corridor, which forms elongated paths or areas. This study assessed the carbon sequestration of 17 primary road networks in Pontianak City using three allometric models. Plot positions for data collection were determined using purposive sampling, with each side accounting for 5% of the total zigzag plots. This research focused on vegetation at different growth stages, such as saplings, poles, and trees. The results were estimated at 256.86 tons ha-1 (Hardiansyah and Ridwan formula), 269.96 tons ha-1 (Chave formula), and 193 tons ha-1 (Brown formula).
