Abstract

Utilization of coastal waters for aquaculture activities or for other activities provides positive value for human welfare but can also provide the potential for reducing water quality. The decline in environmental quality can be seen from changes in components such as biology, chemistry, and beach physics. Changes in chemical and physical components cause sediment to decrease, which will affect the life of marine biotas, such as the community structure, especially the slow-moving and relatively settled biota on the bottom of the waters (macrozoobenthos). Macrozoobenthos are very appropriate to be used as an indicator of changes in water quality due to their benthic nature which is relatively silent or has low mobility so it is strongly influenced by the environment. The purpose of the study was to determine the structure of the macrozoobenthos community and the condition of seawater quality. There were 25 species of gastropods and 3 other classes. The macrozoobenthos species diversity index on the Benoa Bay Coast showed a moderate level of diversity with the highest value of 2.4576. The uniformity index at each station ranges from 0.0894 – 0.5337. The value of the dominance index ranges between 0.000004-0.7656. Based on the relative abundance, the macrobenthos community is dominated by the Gastropod class. The temperature values ??at each station were relatively the same, ranging from 29.3°C– 30.8°C, and the pH was in accordance with quality standards for macrozoobenthos growth. Some indicators of water quality are still below the quality standard threshold, but the concentration of phosphate (PO4) at all locations is already above the predetermined quality standard of 0.015 mg/L?.

Abstract

This study aimed to evaluate the effects of ex-situ habitat transfer on physiological and behavioral stress responses in Indo-Pacific bottlenose dolphins (Tursiops aduncus) and to assess the effectiveness of environmental enrichment in mitigating stress and enhancing welfare. Seven dolphins were monitored across four periods: before transfer, immediately upon arrival at the new facility, after 15 days of adaptation, and following 30 days of environmental enrichment using interactive toys. Parameters measured included neutrophil-to-lymphocyte (N/L) ratio, respiratory rate, frequency of stereotypic behaviors, food intake, social interactions, and compliance with trainer commands. The results demonstrated that habitat transfer induced significant increases in N/L ratio and respiratory rate. A 15-day adaptation period was insufficient to restore physiological and behavioral parameters to baseline levels. However, after 30 days of environmental enrichment, stress indicators improved markedly, with decreased N/L ratios, normalized respiratory rates, reduced stereotypic behaviors, and increased food intake, social interactions, and compliance. These findings underscore the importance of integrating structured environmental enrichment strategies into ex-situ conservation and management programs to support optimal welfare in captive dolphins.

Abstract

Many public and organizational programs achieve technical success, regulatory compliance, and high budget absorption, yet fail to sustain outcomes once external support ends, as prevailing evaluation frameworks emphasize outputs over sustainability. This gap reflects the absence of an integrated perspective on how institutional conditions shape long-term durability. This paper proposes the Panca Datu Logic Framework (PDLF), where panca denotes “five” and datu foundational elements, as a conceptual guide for sustainability evaluation. Using a conceptual-synthetic approach grounded in abductive reasoning, the framework is illustrated through three case-based simulations in Bali: rabies control, community-based turtle conservation, and waste management programs. The PDLF conceptualizes sustainability as an emergent, non-compensatory property arising from alignment among five domains—legal, human, financial, infrastructure, and culture—with culture positioned as an outcome of systemic coherence. The framework offers an analytical lens to explain both program fragility and sustained performance across institutional and geographical gradients spanning local, national, and global contexts.
