Abstract
The location of Bulukumba Regency, which is traversed by the Walanae Fault, indicates that this area has the potential for earthquakes. The potential for this earthquake is also reinforced by the condition of the Bulukumba Regency landform, which is composed of landforms of volcanic and tectonic origin. The purpose of this study was to analyze the hazard potential of the earthquake through the peak ground acceleration approach and to analyze the relationship between the landform and the peak ground acceleration value in Bulukumba Regency. The methods used in this study are statistical methods, descriptive qualitative, and spatial analysis. The results of this study indicate that the value of peak ground acceleration (PGA) in Bulukumba Regency based on the earthquake historical report for the period 1921-2023 is 67-121 gal. The PGA value, at 67-88 gal with low hazard criteria, is a site on the land from the volcanic process. The PGA value, at 89-121 gal with low hazard criteria, is a site on the land from structural and fluvial processes. Output of this research be expected can become input for the revision of spatial plan in Bulukumba Regency.

Abstract
The Citarum River is the longest and largest river in West Java and is widely used by the community for various purposes. One of the problems that occurs in rivers is the generation of solid waste that flows into the river. Therefore, this study aimed to analyze the abundance and composition of solid waste on the surface of a river during a certain period. The study was conducted from April to June and August to November 2021. Sampling was carried out once a month with three repetitions, namely morning, noon, and evening, at the five sampling stations. Station locations were divided based on the type of flow, namely, on the mainstream of the Citarum River and tributary streams. The sampling of solid waste is carried out using a frame pocket net (FPN) shaped like a net to capture solid waste that flows on the surface of the river. The highest waste abundance was 0.1569 kg/m3· h in the urban areas. The type of waste that dominated the river was organic waste, which reached 62.8%. Other types of solid waste found were macroplastics, hazardous and toxic materials, metals, rubber, textiles, and paper. Solid waste management needs to be carried out based on the area and is sustainable, and can be pursued by implementing 3R (reuse, reduction, and recycling).

Abstract
The construction of Indonesia’s new capital city, Nusantara, is envisioned as a forest city that heavily relies on biodiversity. One of the forest ecosystem types surrounding the Nusantara landscape is the heath forest ecosystem, also known as Kerangas. Heath forest is a rare and extreme habitat, thriving in nutrient-poor environments characterized by low pH, quartz sand soil, and podsol soil. However, there is still a lack of knowledge regarding the heath forest in East Kalimantan, particularly in the Nusantara region. This research aims to map the location and characteristics of the heath forest in the surrounding area of Nusantara, specifically in Penajam Paser Utara Regency and Kutai Kartanegara Regency, East Kalimantan. The creation of a tentative heath forest map requires four parameters: elevation, soil texture, NDVI, and a land cover map. Landsat 9 imagery was employed to conduct unsupervised classification and generate a land cover map. The Normalized Difference Vegetation Index (NDVI) was also applied as an image transformation. The parameters were then overlaid using Geographic Information System (GIS) with a binary model. The results indicate that the heath forest covers an area of 56,646 hectares, representing 23% of the total Nusantara area, while the non-heath forest covers 194,610 hectares. The heath forest tentative map aligns with the RePPProT (Regional Physical Planning Project for Transmigration) land system map. Kerangas forests exhibit unique vegetation types, characterized by stunted trees, shrubs, and various epiphytes. Due to the nutrient-poor soil conditions, the vegetation in heath forests is typically sparse and of low height.

Abstract
In agricultural activities, fertilization is important. However, in some cases, plants can grow well without continuous fertilization. This due to the influence of plant litter and the presence of undergrowth which is a source of organic matter that supplies nutrients to the soil. The objectives of this study were to know the dynamic of nutrient release from litter decomposition and to find out the amount of nutrient content provided by decomposition of A. mangium and Nephrolepis sp. litter. Fresh litter of A. mangium and Nephrolepis sp. were put in the open area in a 0.2 m2 container with a water tank underneath. The leachate was taken every week, then the macro and micronutrients were analyzed in the laboratory. The results showed that the nutrients in the litter were released gradually through the leaching process from the first week of experiment. This indicates that since the beginning of decomposition process, the nutrients released can be used by plants. The highest nutrient released was potassium equivalent to 76.1 kg K ha−1year−1 for A. mangium and 114.7 kg K ha−1year−1 for Nephrolepis sp. Thus, the presence of litter and undergrowth has the potential to be used as fertilizer and contribute to providing nutrients for plants.

Abstract
Cibodas Botanic Gardens (CBG) is an ex-situ conservation area in tropical highlands. Termites are one of the nuisance organisms in the collection that have conservation value. The number of attacks and the intensity of termite attacks require more strict attention. The main problem in tree health analysis is the difficulty in detecting internal weathering due to attacks by wood-destroying organisms which causes damage to the tree’s core (heart rot) and butt rot. Arborsonic is a tool used and developed to detect and assess tree damage, especially to the trunk. This study aimed to analyze the deterioration of the main trunk of a living tree with visual signs of termite attack using a non-destructive method. Termite observation plots were made in 4 replications to determine the type of termites that attack. Observations on termite baits in 4 plots showed no attack on the baits. Observations on 12 sample trees tested in 4 plots showed low-intensity damage. Visual signs of termite attack can be used as a sign of wood decay, but the effect is minor.

Published: December 2023

Abstract
In Sri Lanka, there is a considerable increase in the average annual LST in the city of Colombo, and it might have occurred in the city of Kandy as well. Increases in LST can affect to many issues. Research on LST is useful for green city planning and policymaking for development in urban areas. This study examined the spatial and temporal variation of LST in the Kandy District in 1996 and 2017. Geospatial tools such as remote sensing and GIS were used to analyse data. Landsat satellite data has been collected by the United States Geological Survey. The NDVI, NDBI, and NDWI were used to classify the different land uses and to find out the relationships between LST. The mean LST was increased by 2.36°C in 2017 compared to 1996. The LST was higher in the City of Kandy in 2017 than in 1996. The Eastern part of the Kandy was slightly higher in 2017 than in 1996. There is a significant negative correlation (α=0.01) between LST and NDVI. The NDBI increased by 0.11 in 2017, compared to 1996 and spread into suburb areas. The significant strong relationship between NDBI and LST was identified. The lack of satellite images is one of the serious barriers to analysing the LST. Land-use changes, increased build-up areas and decreases in vegetation and water bodies have affected to rise in land surface temperature in the Kandy. The future land use planning should be considered to mitigate the effects of LST in Kandy City.

Abstract
Geronggang (Cratoxylum arborescens) is one of native tree species of tropical peat swamp forest which has a good potency both planted for rehabilitation and industrial purposes. Nevertheless, before this tree species can be cultivated on a large scale, much silviculture knowledge and technology must be accessible, including the technique of seedling propagation. This study evaluated the growth and quality of geronggang seedlings grown in different mediums and containers. The seedling was grown in topsoil (M1) and peat (M2) medium with three containers (C1 = plastic pot (volume (v) = 120 mL); C2 = plastic pot (v = 300 mL) and C3 = polybag (v = 400 mL)). As the control, the seedling was also grown in topsoil + compost medium combined with polybag (M3C3). Growth (height (H), collar diameter (D), and biomass) and morphological ((shoot/root (S/R), D/H) and Dickson quality index (DQI)) attributes of the seedling and medium properties were observed. Peat medium had better results than topsoil (p < 0.05). Furthermore, the seedlings grown in peat medium had the highest performance. M2W3 was the treatment with adequate quality to be outplanted at nine months, with H, D, S/R, H/D, and DQI were 25.4 cm, 3.6 mm, 6.94, 1.37, and 0.36, respectively. The results indicated that using peat alone as a medium in geronggang seedling propagation was relatively time-consuming.

Abstract
To address challenges in soil erosion management and ecological rehabilitation, understanding the determinants of soil erosion is crucial. This research aims to achieve two primary objectives: (1) delineating the spatial patterns of soil erosion within the designated region and (2) identifying the influential factors using the Multiscale Geographical Weighted Regression (MGWR) methodology. The methodological framework involved the creation of grid datasets, with soil erosion as the response variable and a combination of physical and socioeconomic attributes as predictors. We extracted 550 data points from raster datasets, specifically centered on village locations, using the ‘extract multi-value to point’ tool in ArcGIS. The R Studio environment was utilized to select the relevant factors influencing soil erosion. The geographical detector technique was applied to determine the explanatory power of each determinant concerning the spatial patterns of soil erosion. Subsequently, data from the Ordinary Least Squares (OLS) model underwent MGWR analysis. The findings reveal that the Central Citarum Watershed experiences an estimated annual soil erosion of 23.16 million tons, averaging 102.01 tons per hectare. The analysis identified LS (slope length and gradient) and CP (vegetative cover and supportive practices) as the primary variables influencing the spatial variability of soil erosion. Notably, the MGWR model demonstrated enhanced explanatory capacity and effectiveness compared to both the OLS and Geographically Weighted Regression (GWR) methodologies.

Abstract
The area of mangrove forests in Indonesia in 2021, according to the Ministry of Environment and Forestry, is around 3,364,080 Ha; this amount is equivalent to 23% of the world’s mangrove ecosystem, which is from a total of 16,530,000 Ha (FAO, 2005). Information on the condition of mangrove ecosystems is important to know whether or not an area is good. Studies related to the condition of mangrove ecosystems based on environmental quality and mangrove health index to determine the environmental quality and mangrove health are needed for ecosystem management in the future. This article describes the health parameters of mangrove ecosystems that will be analyzed with the help of a combination of decision support software such as fuzzy and ISM so that priority mangrove ecosystem locations can be determined, mangrove health index values to determine the health status of mangrove ecosystems and determine alternative sustainable mangrove ecosystem management policies that will be applied to the object of study. In addition, the study also discusses the concept of determining standard criteria for the level of damage to mangrove ecosystems and determining the status of mangrove ecosystems. Based on fuzzy logic, data analysis shows that the output of the Mangrove Health Index can be determined with 3 variables and 27 rules, with key factors in Mangrove Density, Canopy Cover and Number of saplings. The results of ISM show that management institutions that must be actively involved in supporting the success of sustainable mangrove forest ecosystem management in Batam City are KLHK, DLHK Riau Islands Province, and BPDAS Sei Jang Duriangkang. Proper handling of constraints and management institutions that are actively involved in mangrove forest ecosystem management will ultimately encourage budget effectiveness and efficiency to meet the main goal, namely sustainable mangrove forest ecosystem management in Batam City.

Abstract
Developing crops based on land resources is necessary for increasing cocoa production. This study aims to analyze the potential for developing cocoa based on information on land resources in the form of characteristics and land distribution in the North Luwu District. The distribution of cocoa was interpreted using onscreen satellite imagery. Land suitability data were compiled by matching land characteristics with the Cocoa Land Suitability Criteria. The potential availability of land and directions for crop development were determined based on the overlay results of land suitability classes with land-use maps and area status. Based on this study, the North Luwu District is part of an active tectonic region and has eight soil types: alluvial, regiosol, renzina, kambisol, gleisol, podsolik, mediteran, and oxisol. The land suitability class for cocoa plants was marginally suitable. The total land area that has the potential to develop cocoa plants is 68,804 ha, with the diversification and extensification of the two development patterns. North Luwu District has the potential to develop cocoa plantations with several appropriate agricultural technology efforts to support the increased production and quality of cocoa plants.

Abstract
Tidal swampland is an agroecosystem with distinct characteristics. Studying on this land was very important to support national food security. This study aims to identify the soil characteristics and the potential of tidal rice fields in the Maliku Sub-District, Pulang Pisau Regency, Central Kalimantan Province, Indonesia. Four representative soil profiles were characterized in the field and laboratory to determine the soil’s chemical, physical, and mineralogical properties. The results showed that these soils were generally fine textured, had very acid to acid reaction (soil pH 3.2-4.7), moderate to high C-organic (2-6%), varied potential P2O5 (22-289 mg/100g), low potential K2O (11-17 mg/100g), varied available P2O5 (8.6-56.1 mg/kg), very low exchangeable Ca (<2 cmolc/kg), varied exchangeable Mg (0.6-3.0 cmolc/kg), moderate soil CEC (18-22 cmolc/kg), very low base saturation (<20%), and shallow to very deep (35 - >100 cm) of pyrite depth. The sand fraction mineral is mainly composed of quartz and rock fragments, while the clay fraction is dominated by kaolinite. The lands are marginally suitable for tidal rice fields with the limiting factor being very acid soil reaction and shallow pyrite depth. The application of balanced fertilization, liming, organic matter, minimum tillage, and micro-water control can increase land productivity.
Investigating the influence of 3D building models on pedestrian wind comfort through wind computational fluid dynamics analysis

Published: December 2023

Abstract
Wind flow plays a crucial role in determining pedestrian comfortability in the surrounding environment. However, the shape and detailing of buildings, as well as the angle of the wind, can manipulate the wind flow patterns and velocity. Different urbanized areas have different building shapes and detailing, which can lead to diverse wind flow patterns and velocities, affecting pedestrian wind comfort (PWC). This study utilized wind Computational Fluid Dynamics (CFD) technique to investigate the influence of building models on wind velocity and its impact on PWC. The CFD simulation integrated with a 3D urbanized building model provided wind velocity values throughout the study area, which were used to analyze wind comfort at 1.75m elevation based on Beaufort wind force criteria. The study found that diverse effects due to different building detailing were observed, leading to multiple flow patterns and changes in wind velocity. The downstream building recorded a lower velocity value than the upstream building mainly because of wind flow separation from the building frontal. Wind comfort levels were represented using the Beaufort wind force scale (BWS), and all values fell in level 2 and 3, indicating good wind comfort level because of the BWS ≤ 3. This study highlights the significance of building models in determining wind flow patterns and velocity, which ultimately impacts PWC. Despite the study area involving multiple buildings with different shapes and detailing, the wind comfort levels were found to be suitable for pedestrians.

Published: December 2023

Abstract
Road traffic accident is highly correlated with the behaviour of who is behind the wheel. Reports have shown that Africa as a region leads in the rate of road traffic fatality globally. Despite the growing road safety challenges associated with commercial transport drivers in Africa, and the various interventions by stakeholders to minimise road traffic accidents, little attention is given to the prevalence of the adverse driving behaviour of commercial transport drivers. Consequently, this study, therefore, established a bibliometric analysis to obtain an in-depth understanding of the driving behaviour of commercial transport drivers in Africa. For this study, 219 articles between 1978 and May 21, 2023, extracted from the Scopus database and key bibliometric indicators were established which includes; publication trends, keywords on driving behaviour among commercial drivers, authors, institutions, citation and co-citation analysis, subject categories, and co-occurrence of terms. Furthermore, information collected in this study was analysed using Microsoft Excel and VOSviewer software. The study showcased the views of researchers in terms of Accident risk factors, accident prevention analysis and accident proneness. However, the result revealed insufficient publications in both quantity and quality on commercial vehicle drivers’ behaviour despite the significant contribution of commercial drivers to accidents in Africa. This research established a new direction by linking drivers’ behaviour, and traffic safety with the commercial transport industry and understanding the factors and influence of drivers’ behaviour.

Published: December 2023

Abstract
Local economic development (LED) in rural communities is a vital aspect of achieving balanced national growth and enhancing the well-being of rural households. However, rural areas face unique challenges that necessitate a focused understanding of the determinants influencing their economic development. This paper aims to examine the determinants that influence LED in rural communities, comparing their importance and impact across different rural areas, understanding the interrelationships among these determinants, and providing evidence-based recommendations for policymakers and community leaders. Drawing on a comprehensive analysis of survey data with a sample size of 911, this study investigates a diverse set of eight rural communities selected from four regions and four districts in Ghana. Quantitative data was collected to analyse demographic factors, economic indicators, and infrastructure characteristics of each community. Regression models, namely ordered logistic regression and ordered probit regression and factor analysis was employed to identify significant determinants and their interrelationships. The findings highlighted that the key determinants of LED in rural communities are economic capital, human capital, social and governance capital, cultural capital, infrastructure, and environmental capital. These identified key determinants were integrated as a framework for policymakers and community leaders to prioritize and design targeted interventions and policies that address the unique needs and challenges of rural areas. The findings highlight the significance of investing in human capital, economic resources, social and governance structures, cultural assets, infrastructure, and environmental sustainability to promote inclusive and sustainable economic growth. Hence, the study contributes to the academic literature on rural economics and serve as a foundation for further research in the field. By investigating the multidimensional determinants that influence LED in rural communities, this study aims to provide valuable insights and recommendations for fostering employment creation, poverty reduction, sustainable development, reducing disparities, and enhancing the overall well-being of communities in rural areas.
