Abstract

Tourism activity in Trisula waterfall (locally called Coban Trisula) is growing significantly. The environmental management is important to perform the sustainable use of waterfall as tourism attraction. The aim of the research is to identify the ecosystem services of Trisula waterfall. In this study, three indices were calculated, namely Environmental Services Index, Hemeroby Index, and Naturalness index. This study found that the use of lands and natural resources in Trisula waterfall was low compared the upper and lower area. Lower and upper area was used for intensive agriculture and daily needs by local community. Those activities were influencing the environmental services of Trisula waterfall. Management towards sustainable use of Coban Trisula area was required. It is also important and should be able to promote security and satisfaction aspects for tourist. Anthropogenic activities such as plantation activities should be controlled by a persuasive approach to minimize disruption to the ecosystem. There are needs for environmental management to ensure the sustainability use of waterfall resources and its surrounding area.Keywords: sustainable tourism, waterfall management, water conservation.

Abstract

Pusat Konservasi Iwak Kali (PAKWALI) in Bakalan village, Pasuruan, holds significant potential for freshwater biodiversity conservation, but faces major challenges from environmental pollution, exploitation of native fish species, and limited infrastructure support. This community services program aimed to strengthen conservation efforts through community empowerment, education, and facility support. The main objectives were to raise awareness of local fish conservation, improve water quality management, and build capacity through participatory training. The program was implemented through several stages, including site assessment, installation of basic facilities such as fish nursery ponds and water quality monitoring tools, community education workshops, and post-activity evaluation. Pre- and post-test analysis showed improvements in cognitive, affective, and psychomotor dimensions. Affective scores increased from 4.25 to 4.62 (p = 0.023), indicating a statistically significant improvement in participants’ conservation attitudes. Results showed increased community understanding of freshwater ecosystems, greater awareness of the importance of native fish species, and growing motivation among participants to adopt sustainable fish farming practices. Additionally, the use of standardized recording formats and expanded partnerships with academic and environmental institutions supported the long-term sustainability of the program. The initiative demonstrates the effectiveness of local based conservation efforts in integrating ecological education with practical community-based action.

Abstract

Riparian forests, vegetation areas located along rivers and other water bodies, play a crucial role in maintaining the ecological integrity of a landscape. This study aimed to examine vegetation and insect diversity and analyze soil and water conditions in the Toyomarto, Candirenggo, and Ardimulyo riparian forest areas. An experimental method was used, establishing 16 plots at 8 stations in the designated area. The results showed 14 species of riparian vegetation, dominated by species such as Oryza sativa, Synedrella nodiflora, and Phyllanthus urinaria, with diversity levels varying from moderate to low. The aerial insect community consisted of 20 species with 39 individuals, with the highest diversity at stations with more complex vegetation structures. Stations with low vegetation showed the dominance of one insect species, indicating severe habitat degradation. Abiotic factors such as pH, temperature, and humidity influenced insect activity but played a secondary role compared to vegetation structure. This study demonstrated that habitat fragmentation can lead to ecological imbalance, decreased biodiversity, and disrupted ecosystem function.

Abstract

Management of small pelagic fish resources for sustainable use requires scientific information related to exploited fish resources, related to species composition, and community structure, including conservation status. This study aims to analyze the species composition, frequency of occurrence, community structure, and conservation status of small pelagic fish caught by fishermen. This study was conducted in April - May 2025 at the Fish Auction Place and Fishermen's Fish Market at Pondokdadap Beach Fishing Port, Sendangbiru, Malang Regency, East Java. The method used was direct observation with species identification and analysis of species composition, frequency of occurrence, and community structure. The results showed that the small pelagic fish group consisted of six species with a total of 5,332 individuals, dominated by Rastrelliger brachysoma and Decapterus macarellus, with the highest composition and frequency of occurrence. The community structure of small pelagic fish includes Diversity and Dominance indices which are in the low category with values of 1.20 and 0.38, respectively, and the Evenness index which is in the unstable category with a value of 0.67. The species composition and community structure of small pelagic fish fluctuate significantly daily and seasonally, linked to the dynamics of environmental parameters that influence fish biological activity, as well as the complexity of the food chain and fishing pressure. The varying catch sizes of individual small pelagic fish species indicate low gear selectivity. Therefore, regulations governing biologically appropriate fishing practices, supported by further research on reproductive biology and population dynamics, are essential to support sustainable utilization.

Abstract

Sharks are cartilaginous fish that play an important ecological role in marine ecosystems. However, their existence in the wild is very vulnerable to overfishing and habitat degradation. This study aims to identify species and analyze the structure of shark communities as bycatch of fishermen. This study was conducted from April to June 2025 at the Fishermen's Fish Market, Pondokdadap Beach Fishing Port Area, Sendangbiru, Malang, East Java, through observation of morphological characters and interviews as supporting data. Data analysis is descriptive in the form of Tables and Graphs. The results of fish identification include 17 individuals from 3 species representing 2 families from 2 orders, namely Chiloscyllium griseum, Squalus montalbani, and Squalus hemipinnis. All individuals caught are categorized as having entered the adult phase, so they are biologically suitable for capture. The diversity index (H') value is in the low category, the evenness index (E) is in the stressed category, and the dominance index (C) is in the high category. The low number of shark catches landed is due to the publicity of the shark trade ban by the Pondokdadap Coastal Fishing Port authorities and strict sanctions against violators. Despite this, some shark landings are still carried out illegally, reflecting low awareness among fishermen and fish traders, as well as high demand for sharks in the market. Efforts to conserve sharks from overfishing need to be continuously improved through intensive and widespread outreach to various stakeholders to build a shared understanding regarding shark conservation in the wild.

Abstract

The Acanthuridae family is a group of fish that inhabits coral reef ecosystems of medium to large size, generally found in various types of coral reef habitats with diverse live coral cover. This study aims to analyze the abundance, frequency of presence, and community structure of fish from the Acanthuridae family landed by fishermen at the Fishermen's Fish Market in the Pondokdadap Coastal Fishing Port. The study lasted for three months (April - June 2025) with sampling times every two weeks. Data analysis includes relative abundance, frequency of presence, and community structure (Diversity, Evenness, and Dominance indices). The results of the study identified eight fish species from the Acanthuridae family with a total of 79 individuals, Acanthurus xanthopterus with 44 individuals with a relative abundance of 56%, and a frequency of presence of 83% which is categorized as commonly found. Community structure values including the diversity index are categorized as low, the evenness index is unstable, and the dominance index is low. The conservation status of four species (50%) of fish is Least Concern (Acanthurus lineatus, Acanthurus xanthopterus, Naso elegans, and Naso unicornis). While the other 50% of species are categorized as Data Deficient (Naso tuberosus, Naso reticulatus, Ctenochaetus binotatus, Prionurus chrysurus). However, continuous monitoring of the catch level and population status of fish of the Acanthuridae family in the waters of the Sempu Strait directly adjacent to the Pondokdadap Coastal Fishing Port is needed to provide important information in determining the appropriate fisheries management model.

Abstract

The food industry sector, particularly fish cracker production, contributes significantly to the economy; however, it also has the potential to pollute the environment through wastewater containing high levels of organic matter. If discharged without proper treatment, this waste can degrade water quality, reduce dissolved oxygen (DO) levels, generate unpleasant odors, and cause the death of aquatic biota. This study aimed to determine the level of water pollution using the Pollution Index method in irrigation rivers surrounding the fish cracker production unit UD. X. The method used was a comparative quantitative descriptive survey with grab sampling conducted at three stations: upstream, wastewater outlet, and downstream. The analyzed parameters included physical parameters (temperature, TDS, odor, and color), chemical parameters (pH, DO, and BOD), and microbiological parameters using the plate count method. The results showed that the pollution index values in the upstream section ranged from 4.1–5.1, which falls into the lightly to moderately polluted category. At the wastewater outlet, the pollution index values ranged from 2.5–4.4, while the downstream section ranged from 2.5–3.7; both were classified as lightly polluted. The water quality status indicated that the upstream section was categorized as lightly to moderately polluted, whereas the wastewater outlet and downstream sections were categorized as lightly polluted. A positive correlation was found between organic load (BOD) and microorganism abundance, where the highest abundance value of 1.78 × 10⁷ CFU/mL was identified at locations with higher BOD levels. Self-purification occurred in the area before the wastewater outlet due to the presence of a small dam that slowed water flow, increased oxygen input, and enhanced the degradation of organic matter. Keywords: river water, wastewater, pollution index, fish crackers ABSTRAK Sektor industri makanan, khususnya produksi kerupuk ikan, berkontribusi signifikan terhadap perekonomian, namun berpotensi mencemari lingkungan melalui limbah cair dengan kandungan bahan organik tinggi. Limbah dapat menurunkan kualitas perairan apabila dibuang tanpa pengolahan, penurunan oksigen terlarut (DO), timbulnya bau, serta kematian biota akuatik. Penelitian ini bertujuan untuk menentukan tingkat pencemaran air menggunakan metode Indeks Pencemaran (IP) pada sungai irigasi di sekitar unit produksi kerupuk ikan UD. X. Metode yang digunakan adalah survei deskriptif kuantitatif komparatif dengan pengambilan sampel secara grab sampling pada tiga stasiun, yaitu hulu, outlet limbah, dan hilir. Parameter yang dianalisis meliputi fisika; suhu, TDS, bau, warna, kimia; pH, DO, BOD, dan mikrobiologi dengan metode lempeng. Hasil penelitian menunjukkan, nilai indeks pencemaran pada bagian hulu berkisar 4,1–5,1 yang termasuk dalam kategori tercemar ringan hingga sedang. Pada outlet limbah, nilai indeks pencemaran berkisar 2,5–4,4, pada bagian hilir berkisar 2,5–3,7, keduanya termasuk dalam kategori tercemar ringan. Status mutu air menunjukkan bahwa bagian hulu berada pada kategori tercemar ringan hingga sedang, sedangkan outlet limbah dan hilir termasuk dalam kategori tercemar ringan. Terdapat korelasi positif antara beban organik (BOD) dengan kelimpahan mikroorganisme, di mana nilai kelimpahan tertinggi mencapai 1,78 × 10⁷ CFU/mL ditemukan pada lokasi dengan BOD yang lebih tinggi. Self-purification terjadi pada lokasi sebelum outlet limbah dengan adanya dam kecil yang memperlambat aliran, masuknya oksigen, dan meningkatkan degradasi bahan organik. Kata kunci: air sungai, air limbah, indeks pencemaran, kerupuk ikan
