Spectral Reflectance-Based Mangrove Species Mapping from WorldView-2 Imagery of Karimunjawa and Kemujan Island, Central Java Province, Indonesia

Mangrove mapping at the species level enables the creation of a detailed inventory of mangrove forest biodiversity and supports coastal ecosystem management. The Karimunjawa National Park in Central Java Province is one of Indonesia’s mangrove habitats with high biodiversity, namely, 44 species representing 25 true mangroves and 19 mangrove associates. This study aims to (1) classify and group mangrove species by their spectral reflectance characteristics, (2) map mangrove species by applying their spectral reflectance to WorldView-2 satellite imagery with the spectral angle mapper (SAM), spectral information divergence (SID), and spectral feature fitting (SFF) algorithms, and (3) assess the accuracy of the produced mangrove species mapping of the Karimunjawa and Kemujan Islands. The collected field data included (1) mangrove species identification, (2) coordinate locations of targeted mangrove species, and (3) the spectral reflectance of mangrove species measured with a field spectrometer. Dendrogram analysis was conducted with the Ward linkage method to classify mangrove species based on the distance between the closest clusters of spectral reflectance patterns. The dendrogram showed that the 24 mangrove species found in the field could be grouped into four levels. They consisted of two, four, and five species groups for Levels 1 to 3, respectively, and individual species for Level 4. The mapping results indicated that the SID algorithm had the highest overall accuracy (OA) at 49.72%, 22.60%, and 15.20% for Levels 1 to 3, respectively, while SFF produced the most accurate results for individual species mapping (Level 4) with an OA of 5.08%. The results suggest that the greater the number of classes to be mapped, the lower the mapping accuracy. The results can be used to model the spatial distribution of mangrove species or the composition of mangrove forests and update databases related to coastal management.

Drivers and barriers in the adoption of green supply chain management in construction projects: A case of Indonesia

The concept of Green Supply Chain Management (GSCM) is attracting attention to the construction industry to minimise adverse environmental effects. However, its application is not common in developing countries like Indonesia. Based on contractors’ and construction design consultants’ point of view, the current study attempts to identify the drivers and barriers to adopting GSCM in construction projects in Central Java Province, Indonesia. The research study used previous literature, observation, questionnaires, and in-depth interviews with experts on drivers and barriers to implementing Green Supply Chain Management in construction. Data were analysed using SPSS and evaluated by the ordinal regression analysis method. Based on testing in ordinal regression analysis, seven factors were identified as drivers or barriers to the adoption of GSCM in construction projects in Central Java Province, and four of them affect significantly. The driving factors that significantly affect the adoption of GSCM include government regulations on environmental protection and pressure from the supply chain stakeholders. On the other hand, the barrier factors include the shortage of suppliers who implement GSCM practices in the construction area and inadequate knowledge and awareness about the impact of construction activities on the environment. This work could give the policymakers’ insight into the barriers and drivers to GSCM, thus enabling them to develop strategies in implementing GSCM in the construction industry.

How Does Human Capital Spillover Inflow of Foreign Workers Affect Economic Growth?

The ASEAN Economic Community provides opportunities for foreign workers to enter Indonesia, including Central Java Province. The existence of these foreign workers tends to negatively and positively impact the regional economic growth of the country. Therefore, this study aims to analyze the effects of foreign workers’ human capital spillover inflow on the economic growth of Central Java. The Euclidean distance spatial weight matrix was used to calculate the spatial autoregressive model from 2015 to 2020. These results indicate that the presence of skilled foreign workers positively impacts increasing economic growth in Central Java Province. The influx of foreign workers, along with the influx of investment, encourages local workers to follow the performance of foreign workers. This study suggests a policy to encourage technology transfer from foreign workers to local workers. The government is also expected to strengthen local workers’ productivity to compete with foreign workers.
