Externalities on The Conversion of Mangrove into Salt Pond in Bipolo Village, Sulamu District, Kupang Regency, East Nusa Tenggara

The utilization of mangrove forest land for the expansion of salt pond areas with the aim of increasing salt production in Bipolo Village causes the loss of economic value of marine biota in the mangrove ecosystem. Mangrove ecosystem resources that are utilized as salt ponds if not accompanied by a rehabilitation process will cause a decrease in the function of the mangrove ecosystem. This will later become a challenge as well as create externalities that need attention from the Kupang district government in regulating the utilization of the mangrove ecosystem in Bipolo Village. This study aims to analyze the positive and negative externality values ??resulting from the development of salt pond businesses in Bipolo Village, Sulamu District, Kupang Regency. To determine the positive and negative externality values ??using the economic valuation method. Based on the results of the study, it is known that the salt pond business in Bipolo Village provides a negative externality value of Rp. 21,439,466,084 and a positive externality value of Rp. 235,280,000 which means that the opening of salt pond land has caused losses from the ecological side of the mangrove which is quite large compared to the benefits obtained.

The existing conditions of distribution parameters of physical and chemical factors of salt pond land on the Coast of Palang District, Tuban Regency, Indonesia

The purpose of this study was to determine the distribution value of physical and chemical factors that affect salt pond land. We employed a method to assess the current state of salt ponds in coastal regions. We conducted this study in Palang District, Tuban Regency, from May 1 to June 1, 2024. This research method involves various methods, including remote sensing and geographic information systems (GIS), to map and analyze land conditions. We will use data from satellite imagery and field measurements to evaluate the physical and chemical parameters for the development of salt ponds. Based on the research data, we have established that the physical and chemical parameters of salt pond land on the coast of Palang District, such as salt table height, seeding place, main embankment, intermediate embankment, pH, and pond bottom, are in good condition and meet the requirements for salt pond land development. In conclusion, the chemical parameters show that the quality of water and soil in salt ponds is still within acceptable limits, although there are several locations that show values approaching the standard quality threshold. We recommend implementing sustainable management practices in the development of salt ponds, which include periodic monitoring of physical and chemical parameters, further research on the impacts of climate change, and collaboration between government, academics, and communities in managing sustainable salt ponds and formulating policies that support the development of the salt industry in coastal areas.

Image Data Acquisition and Classification of Vannamei Shrimp Cultivation Results Based on Deep Learning

This research aimed to employ deep learning techniques to address the classification of Litopenaeus vannamei cultivation results in land ponds and tarpaulin ponds. Despite their similar appearance, distinguishable differences exist in various aspects such as color, shape, size, and market price between the two cultivation methods, often leading to consumer confusion and potential exploitation by irresponsible sellers. To mitigate this challenge, the research proposed a classification method utilizing two Convolutional Neural Network (CNN) architectures: Visual Geometry Group-16 (VGG-16) and Residual Network-50 (ResNet-50), renowned for their success in various image recognition applications. The dataset comprised 2,080 images per class of vannamei shrimp from both types of ponds. Augmentation techniques enhanced the dataset’s diversity and sample size, reinforcing the model’s ability to discern shrimp morphology variations. Experiments were conducted with learning rates of 0.001 and 0.0001 on the Stochastic Gradient Descent (SGD) and Adaptive Moment Estimation (ADAM) optimizers to evaluate their effectiveness in model training. The VGG-16 and ResNet-50 models were trained with a learning rate parameter of 0.0001, leveraging the flexibility and reasonable control provided by the SGD optimizer. Lower learning rate values were chosen to prevent overfitting and enhance training stability. The model evaluation demonstrated promising results, with both architectures achieving 100% accuracy in classifying vannamei shrimp from soil ponds and tarpaulin ponds. Furthermore, experimental findings highlight the superiority of using SGD with a learning rate of 0.0001 over 0.001 on both architectures, underscoring the significant impact of optimizer and learning rate selection on model training effectiveness in image classification tasks.

Hourly methane and carbon dioxide fluxes from temperate ponds

AbstractPonds are regarded as greenhouse gas (GHG) emission hot spots, but how hot are they? We examined this question by measuring methane (CH4) and carbon dioxide (CO2) fluxes in six forest and open land ponds on grasslands in Denmark during summer and winter. We used floating chambers with do-it-yourself sensors and automated headspace venting, allowing for 7404 hourly measurements. We found highly variable gas fluxes within ponds and between seasons and pond types. Ebullitive CH4 fluxes were more variable than diffusive CH4 fluxes. Ebullition was absent when total CH4 fluxes were lowest (15 µmol m−2 h−1), dominant (> 90%) at the highest fluxes (> 400 µmol m−2 h−1), and increased with water temperature. In summer, a minor daily increase in diffusive fluxes was found on days with high wind speed, while CH4 ebullition remained constant. CO2 fluxes paralleled the day-night balance of photosynthesis and respiration. Mean CH4 ebullition in open and forest ponds exceeded CH4 diffusive fluxes 4.1 and 7.1-fold in summer (avg. 22.5 °C) and 2.3 and 2.5-fold in winter (9.6 °C), respectively. CO2 emissions were higher on a molar basis than CH4 emissions, both in summer and winter, while their annual global warming potentials were similar. Mean annual gas emissions from open and forest ponds (1092 and 2527 g CO2e m−2 y−1) are naturally high due to extensive external input of dissolved CO2 and organic carbon relative to pond area and volume.
