Abstract

The mangrove ecosystem in Sungsang IV Village, South Sumatra has degraded mainly due to climate change. To address this, a strategy for managing and conserving mangrove ecotourism is needed, emphasizing the role of tourists in generating economic value. Willingness to Pay (WTP) is an approach that can be used to measure economic value based on tourists' willingness to pay as an effort to develop mangrove ecotourism. The Contingent Valuation Model (CVM) in assessing WTP is used to project the economic value of the environment, especially benefits that are not available in the market. Factors that influence tourist WTP can be identified by binary logistic regression analysis. The average WTP value of mangrove ecotourism tourists is IDR 17,333 or IDR 17,500 per tourist per four months or IDR 52,500 per tourist per year. Factors that significantly influence WTP are age and cost of getting to the location. One strategy that can be done for the development of mangrove ecotourism in Sungsang IV Village is to utilize programs to overcome climate change in developing mangrove ecotourism. This study’s findings will help policy makers in promoting mangrove conservation and enhaching local community livelihoods.

Abstract

The excessive use of synthetic chemical inputs in agriculture has led to soil degradation, highlighting the need for environmentally friendly bioactivator alternatives. This study aims to integrate bibliometric analysis and experimental evaluation of Photosynthetic Bacteria (PSB) and Jakaba (Corallomycetella repens) as bioactivators in organic farming systems. Bibliometric analysis was conducted using Scopus publications from 2015–2025 and visualized with VOSviewer to map research trends, dominant keywords, and the publication status of PSB and Jakaba. A field experiment was then carried out in Kaluku Tinggu Village, Sigi District, using hybrid corn (Bisi-18) with four treatments: control, PSB, Jakaba, and a combination of PSB+Jakaba. Data were analyzed using ANOVA and Tukey HSD test, supported by Response Surface Methodology (RSM) for treatment effectiveness evaluation. Results showed that the PSB+Jakaba combination increased plant height (15.3%), fresh weight (20.9%), dry weight (25.1%), soil pH (13.5%), organic C content (41.2%), cation exchange capacity (27.6%), microbial population (24%), and dehydrogenase activity (36.3%) compared to the control. Active compounds such as IAA and siderophores from PSB, along with lignocellulolytic enzymes from Jakaba, played key roles in improving soil quality. This study bridges the scientific knowledge gap and reinforces the potential of local bioactivator formulations for sustainable organic farming on marginal land.

Abstract

Tuberculosis (TB) is an infectious disease that remains a global health problem, including in Indonesia. In addition to the physical impact, pulmonary TB patients are also susceptible to psychological disorders such as depression, which may arise due to concerns about symptoms and treatment. Depression ranks first among mental health disorders in Indonesia. This study aims to determine the correlation between the phases of TB treatment and depression levels in pulmonary TB patients. This study employed an analytical observational design with a cross-sectional approach and used consecutive sampling. Data were collected from February 17 to June 8, 2024, using the Beck Depression Inventory-II (BDI-II) questionnaire. A total of 38 pulmonary TB patients participated in this study with 6 experiencing depression of varying severity. Spearman correlation test showed no statistically significant association between the phases of TB treatment and depression levels (p= 0.093). Based on these results, it can be concluded that there is no significant correlation between the phases of TB treatment and depression levels in pulmonary TB patients at Puskesmas Putat Jaya, Surabaya.

Abstract

This study proposes a deep learning-based classification system to identify chicken breeds from image data. A dataset of 2,400 labeled images representing twelve distinct chicken breeds was collected and divided into training, validation, and testing sets. The system employs transfer learning by integrating the Mobile VGG16 convolutional neural network as the feature extraction backbone. The extracted features were then passed through custom classification layers to differentiate among the breeds. The model was trained using 1,800 images, validated with 300 images, and evaluated on a separate test set of 300 images. During testing, the model achieved an accuracy of 81% and a categorical cross-entropy loss of 0.378. These results indicate that the model can effectively recognize subtle visual distinctions between similar-looking chicken breeds. The system demonstrates practical potential for applications in poultry farming, biodiversity documentation, and automated livestock management. The findings confirm that deep convolutional neural networks, particularly VGG16 in a transfer learning setup, are capable of performing fine-grained classification tasks in real-world scenarios. The proposed method provides a reliable and scalable solution for automatic chicken breed identification based on image input.
