Analysis of Factors Influencing Community Participation in Sustainable Forest Management in BKPH Mojorayung, Madiun

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

Local Wisdom of Pest Attack Control in Residential Areas (Study Case: Gunung Meja Nature Park, West Papua, Indonesia)

Healthy plants can be seen from good morphology and are not even attacked by pests. Local community knowledge of seeing symptoms and signs of plant stature will be very helpful, especially in dealing with problems related to plant growth. This study aims to determine the form of local wisdom in dealing with plant pests in residential areas around the Gunung Meja Nature Park. The method used is observation and interviews related to the identification of forms of attack, the level of pest attack on plants, and their handling by the community.

Modeling Landslide Hazard Using Machine Learning: A Case Study of Bogor, Indonesia

Landslides occur in many parts of the world. Well-known drivers, such as geological activities, are often enhanced by violent precipitation in tropical regions, creating complex multi-hazard phenomena that complicate mitigation strategies. This research investigated the utility of spatial data, especially the digital elevation model of SRTM and Landsat 8 remotely sensed data, for the estimation of landslide distribution using a machine learning approach. Bogor Regency was chosen to demonstrate the approach considering its vast hilly/mountainous terrain and high rainfall. This study aimed to model landslide hazards in Sukajaya District using random forests and analyze the key variables contributing to the isolation of highly probable landslides. The initial model, using the default settings of random forest, demonstrated a notable accuracy of 93%, with an accuracy ranging from 91 to 94%. The three main predictors of landslides are rainfall, elevation, and slope inclination. Landslides were found to occur primarily in areas with high rainfall (2,668–3,228 mm),elevations of 500 to 1,500 m, and steep slopes (25–45%). Approximately 4,536 ha were potentially prone to landslides, while the remaining area (> 12,000 ha) appeared relatively sound

Construction projects are among the sectors that are growing rapidly in Indonesia and have an impact on the environment from the resulting construction waste. The purpose of this study is to analyze the highest type and quantity of construction waste generated from Mechanical Electrical Plumbing (MEP) work from the difference in the amount of material from the BOQ with the amount attached to the as-built drawings, evaluate the economic value by calculating the ratio of the amount of waste generated to the amount of material at BOQ (waste level) × the scope of work percentage (waste cost), selling value of waste (the quantity of waste × the local selling price), and costs of disposal of construction waste based on the agreement of each project management. This study uses a descriptive quantitative method. The results showed that most of the construction waste generated was based on its type, consisting of copper-based cables, steel and plastic pipes, and polyurethane ducts. The highest quantity of construction waste came from the office project, which was 2 × 1.5 mm2 NYA cables (216,515 m). The highest waste level value came from office, condotel, and factory projects using several types of cables (> 94%). The highest waste cost value came fromthe condotel project is polyurethane duct (IDR 5,727,267,000.00). The metal waste produced is sold by contractors to collectors for recycling. Non-metal waste is disposed by paying a civil contractor. Construction waste management policies must be implemented to reduce the amount and impact of construction waste generated. Proyek konstruksi merupakan salah satu sektor yang berkembang pesat di Indonesia dan berdampak pada lingkungan dari limbah konstruksi yang dihasilkan.

Indonesian Big Agrarian Data: A Contextual-Based Interpretive Structural Model

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

Marine Debris Pollution and Its Impact on the Mangrove Ecosystem (Case Study: Karimunjawa Island and Kemujan Island, Indonesia)

Coastal areas possess a diverse potential wealth of natural resources that can be developed and utilized by humans, such as fisheries, marine tourism, and transportation. One form of disruption to the balance of coastal and marine ecosystems is the pollution caused by waste. The Karimunjawa Islands face serious challenges related to waste pollution. Therefore, an identification of carried out regarding the composition of polluting waste as well as impacts or disruptions caused by marine waste pollution on the mangrove ecosystem in the coastal areas of Karimunjawa Island and Kemujan Island. Various types of waste were found at the research site, including plastic, metal, glass, rubber, organic, and others. Based on the enteri locations of Karimunjawa Island and Kemujan Island, 370 items of plastic waste and macro-debris amounted to 442, predominantly on Lumbung Beach. The dominant mangrove is Rhizophora sp., which has muddy sandy substrate. From the results of this study, it can be concluded that this waste situation makes the coastal areas of Karimunjawa Island and Kemujan Island vulnerable to environmental pollution problems. The impact on the environment is a decrease in benthic biota density owing to the abundance of waste. The higher the density of waste, the lower the density of benthic species found in the mangrove ecosystemenvironment

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

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)
