Abstract

Daya dukung merupakan jumlah maksimum manusia yang dapat ditampung oleh suatu tempat pada saat yang sama tanpa menyebabkan kerusakan fisik, ekonomi atau sosial budaya, dan hal yang menyebabkan berkurangnya kualitas kepuasan pengunjung. Upaya penghitungan daya dukung salah satunya agar tidak terjadi kerusakan pada kawasan wisata yang diakibatkan oleh kelebihan jumlah pengunjung. Nilai ekonomi merupakan nilai yang diberikan bagi suatu kawasan wisata. Penghitungan nilai ekonomi dilakukan untuk mengetahui berapa biaya yang dapat dihasilkan dan digunakan untuk melakukan pengelolaan pada kawasan wisata. Riset ini bertujuan untuk menganalisis daya dukung dan nilai ekonomi pada Kawasan Ekowisata Mangrove yang berada di Kabupaten Pangandaran yaitu Kawasan Ekowisata Mangrove Bojong Salawe, Nusawiru, dan Batu Karas. Metode yang digunakan adalah metode survei yang disebarkan secara online melalui google form kemudian dianalisis secara deskriptif kualitatif dan kuantitatif. Data yang digunakan adalah data primer dan sekunder dengan total responden sebanyak 108 responden. Hasil riset ini menunjukkan bahwa Kawasan Ekowisata Mangrove di Kabupaten Pangandaran belum melebihi kapasitas daya dukung pada masing-masing kawasan. Kawasan dengan daya dukung tertinggi adalah Kawasan Ekowisata Mangrove Batu Karas sebanyak 67 pengunjung per hari, sedangkan kawasan dengan daya dukung terendah adalah Kawasan Ekowisata Mangrove Nusawiru sebanyak 20 pengunjung per hari. Kawasan yang memiliki nilai ekonomi tertinggi adalah Kawasan Ekowisata Mangrove Batu Karas dengan nilai ekonomi sebesar Rp 2.566.110.000 per tahun, sedangkan kawasan yang memiliki nilai ekonomi terendah adalah Kawasan Ekowisata Bojong Salawe dengan nilai ekonomi sebesar Rp 237.857.000 per tahun.

Abstract

Sungai Citarum adalah salah satu perairan darat yang harus dikelola oleh Privinsi Jawa Barat. Sungai tersebut mengaliri tiga waduk, salah satunya Waduk Saguling yang terletak di Kabupaten Bandung Barat. Waduk tersebut berfungsi sebagai Pembangkit Listrik Tenaga Air (PLTA), area budidaya, jalur transportasi. Penurunan kondisi perairan seperti terjadinya eutrofikasi dapat menimbulkan pertumbuhan eceng gondok. Pemantauan langsung secara berkala dibutuhkan tetapi memerlukan biaya dan waktu yang relatif banyak. Maka dari itu diperlukan metode pemantauan yang lebih efisien. Riset ini bertujuan untuk menghitung luasan area yang distribusi eceng gondok di Waduk Saguling dari tahun 2019 sampai tahun 2023. Riset ini menggunakan citra Sentinel-2 dan NDVI dari Snetinel EO Browser pada tahun 2019 sampai 2023 dengan tiga citra per tahun untuk mewakili musim berbeda. Citra satelit diproses dengan klasifikasi tidak terbimbing untuk memperoleh luasan eceng gondok. Uji akurasi dilakukan dengan menempatkan assesment points secara acak pada citra NDVI dan membandingkannya dengan citra yang memiliki resolusi lebih tinggi dari PlanetScope natural colors. Hasil menunjukkan bahwa luasan eceng gondok di tahun 2019 berkisar antara 242,98 sampai 953,55 hektar, tahun 2020 dari 766,21 sampai 1165,12 hektar, tahun 2021 dari 265,55 sampai 1008,77 hektar, tahun 2022 dari 316,21 sampai 407,33 hektar, dan pada tahun 2023 dari 271,29 sampai 1102,6 hektar.  Distribusi eceng gondok umumnya ditemukan di area budidaya dan/atau dekat dengan aktivitas manusia. Sementara yang paling sedikit hingga tidak ada sama sekali berada di area bendungan. Luasan eceng gondok di Waduk Saguling cenderung fluktuatif dengan kenaikan pada musim penghujan. Distribusi dan luasan yang dihasilkan klasifikasi dipengaruhi masukan nutrien dari keramba jaring apung ataupun runoff dan juga gangguan pada sensor satelit yang membatasi kemampuan klasifikasi.

Abstract

Global warming is a phenomenon of increasing the average temperature of the earth's surface. Carbon can be stored in various forms in ecosystems, one of which is the concept of blue carbon. This research aims to analyze the condition of the mangrove ecosystem and the potential for carbon storage in the mangrove forest rehabilitation area in Sebele Village, Karimun Regency, Riau Islands. This research was conducted from October 2024 to July 2025 in the mangrove forest rehabilitation area of Sebele Village, Riau Islands Province. The method used in this research is the survey method. Standing biomass data was obtained using allometric equations. The research results show that the level of tree density in the mangrove forest rehabilitation area of Sebele Village is in the Sparse category. At the tree level, it is dominated by the Xylocarpus granatum species, while at the sapling level it is dominated by the Rhizophora mucronataspecies. The highest carbon storage value is found in the Avicennia marina species with a carbon storage value of 14.44 tons/ha. And the potential carbon storage from the calculation results obtained a carbon storage value of 61.43 tons/ha. The carbon storage value is directly proportional to the standing biomass. The greater the standing biomass, the greater the carbon stored.

Abstract

Kearifan lokal merupakan faktor penting dalam menjaga keberlangsungan ekosistem. Masyarakat memiliki peran utama dalam upaya konservasi berbasis nilai-nilai kearifan lokal yang meliputi pengetahuan dan kepercayaan lokal yang diturunkan turun-temurun secara lisan. Pengetahuan dan kepercayaan lokal masyarakat berpotensi luput dari masyarakat seiring berjalannya waktu karena semakin berkembangnya zaman masyarakat mulai menghiraukan hal-hal yang berbau mistis. Maka studi ini dilakukan untuk mengetahui pengaruh pendidikan dan usia terhadap pengetahuan dan kepercayaan lokal masyarakat terhadap ikan dewa. Hasil studi menunjukan tingkat pendidikan dan usia masyarakat tidak berpengaruh secara signifikan terhadap pengetahuan masyarakat. Namun tingkat kepercayaan masyarakat pada tingkat pendidikan sarjana menunjukan persentase terendah (75%) sedangkan berdasarkan kelompok usia seluruhnya memiliki persentase yang sama (100%). Berdasarkan hasil studi, perlu dilakukan penyuluhan khususnya mengenai pemahaman masyarakat terkait ikan dewa dan habitatnya untuk mengiringi kepercayaan terhadap mitos yang melekat pada masyarakat.

Abstract

Innovations to increase protein content in tortilla chips can be achieved by adding skipjack tuna flour. This study aims to analyze the percentage of skipjack tuna flour addition in the production of tortilla chips that are most preferred by panelists and to analyze the proximate composition of the most preferred tortilla chips. This study was conducted at the Fisheries Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, University of Padjadjaran, and the Laboratory of PT Saraswanti Indo Genetech in February 2025. The research method used was experimental with 4 treatments and 25 semi-trained panelists as replicates. The treatments involved adding skipjack tuna flour to tortilla chips at levels of 0%, 7.5%, 10%, and 12.5%. The parameters observed were organoleptic characteristics (appearance, aroma, texture, taste) and chemical characteristics (protein content, ash content, fat content, moisture content, and carbohydrate content). The data obtained will be analyzed using the Friedman test and Bayes' equation. The study concluded that the addition of 12.5% skipjack tuna flour was the most preferred treatment, with an average score of 6.28 for appearance, 7.64 for aroma, 8.04 for texture, and 8.84 for taste. The alternative value for the treatment with 12.5% skipjack tuna flour addition was 8.21. The proximate analysis results of the most preferred tortilla chip treatment showed a protein content of 7.56%, ash content of 1.82%, fat content of 20.67%, moisture content of 4.35%, and carbohydrate content of 65.60%.

Abstract

Cisanti Lake, the strategic zero point of the Citarum River, faces the threat of cadmium (Cd) pollution from surrounding agricultural activities. Conducted during the dry season of 2024, this pioneering study assesses the Cd pollution status using a multicompartment approach (water, sediment, and bioindicator organism Sinanodonta pacifica, Heude 1878). Samples from the three stations were analyzed using Atomic Absorption Spectrophotometry (AAS). The concentration of Cd in water was very low (0.0012–0.0030 mg/L), but it accumulated significantly in sediment (0.37–0.65 mg/kg) and mussel tissue (0.20–0.30 mg/kg). Although the concentration in water and biota was below quality standards, ecological risk analysis revealed that the sediment has moderate contamination (Contamination Factor: 1.25–2.15) and acts as a long-term pollutant sink. S. pacifica proved effective in accumulating Cd from the water column, demonstrated by a high Bioconcentration Factor from water to biota (BCF b-w >75), making it a reliable bioindicator of Cd pollution. This study provides crucial baseline data on environmental management in the upstream Citarum and establishes sediment monitoring as a vital early warning tool for future pollution risks.

Abstract

This research examined the post-rehabilitation dynamics of the mangrove ecosystem in the Mangrove and Crab Conservation Area, Tarakan, North Kalimantan, four years after the launch of a community-based restoration program in 2019. The objectives were to evaluate species composition, vegetation structure, and the survival of mangrove seedlings within rehabilitated plots. The sampling was done on purpose in areas that show the main ecological features of the site. This study found five types of mangrove trees: Avicennia alba, Rhizophora mucronata, Avicennia marina, Sonneratia alba, and Xylocarpus granatum. It is fewer than the ten species that were there in the past. Among these, Avicennia alba consistently dominated both the mature and seedling stages, recording the highest relative density (72.56%), frequency (42.86%), and canopy cover (78.08%). Its naturally regenerating seedlings reached a survival rate of 52%, substantially higher than the 17% recorded for planted Rhizophora mucronata. The Avicennia alba is particularly well adapted to the prevailing site conditions, mainly owing to its tolerance of sediment disturbance and variable salinity. This outcome highlights the importance of Assisted Natural Regeneration (ANR) that employs locally adapted species, offering a more practical, cost-effective, and sustainable approach than conventional planting methods. Although there have been some improvements, the decrease in species numbers shows the ecosystem is still in the early stages of recovery. To make sure it stays healthy and strong for the future, it is important to keep the water flowing properly, reduce human impact, and keep up with regular checks and monitoring.

Abstract

Mangrove ecosystems play an important role in maintaining coastal biological balance, protecting land from erosion, providing habitats for various biota, and functioning as effective carbon sinks. Indonesia has the largest mangrove area in the world, covering approximately 3.3 million hectares, but this ecosystem continues to experience degradation due to land conversion, with a rate of destruction reaching 530,000 hectares per year. This degradation reduces the ecological and economic functions of mangroves, necessitating vegetation structure analysis to assess the condition of the ecosystem. This study aims to analyze the vegetation structure of mangroves in Pengarengan Village, Pangenan District, Cirebon Regency, which is one of the oldest mangrove areas in Cirebon. Data collection was carried out at three stations using the Transect Line Plot method with plot sizes of 10×10 m² for trees, 5×5 m² for stakes, and 1×1 m² for seedlings. The parameters observed included density, frequency, and dominance, which were then used to calculate the Importance Value Index (IVI). The results showed that the mangrove vegetation at the study site was dominated by the species Rhizophora mucronata and Avicennia marina. The density of tree-level vegetation was classified as moderate to dense, with the highest density found at Station II (2,433 ind/ha) and the lowest density found at Station I (1,200 ind/ha). The INP value reached 300% for each species at all stations at the tree and stump levels, indicating the dominance of one species at each station

Graphical Abstract Highlight Research The results of this research showed that allometric growth in males and females had negative allometric growth characteristics. The growth condition index in male and female fish is dominated by thin and fat body shapes.The maximum length growth (L∞) and growth speed of males is higher than that of females. Total mortality and fishing mortality for males is higher than for females, but natural mortality for females is higher than for males. The exploitation rate of males and females is in the Under-exploitation category because the E value is <0.5. Abstract Exploring the length-weight relationship of fish and characterising growth parameters is essential in fisheries as they offer fundamental biology and population dynamics data to establish good management strategies for fisheries resources. This study examines the growth and mortality patterns of Oreochromis mossambicus. Data was collected between September and December 2022 using quantitative descriptive survey sampling. The study involved 20 repeats and deliberate random sampling of 30-50 fish per sample, emphasising total length, weight, and sex parameters. Based on 726 samples of O. mossambicus (352 fish identified as male and 374 fish identified as female). The growth model study revealed the typical negative allometric growth for both sexes (male and female). Male individuals attained a length of 33.449 cm after 37 days has a growth trend ± 0.3265 year-1, and females reached 21.150 cm in 34 days with a growth rate around 0.3135 year-1, as per the von Bertalanffy growth model. There were complex mortality patterns, with males contributing to most total deaths. This study emphasises the complex biology of tilapia and its untapped potential in the aquaculture pond system ecology in Tarakan.

Abstract

Sungai Cikeruh merupakan Daerah Aliran Sungai (DAS) Citarum yang melintasi Kabupaten Bandung dan Kabupaten Sumedang, yang berada di kawasan tingginya padat penduduk, sehingga mengalami pencemaran pada perairan. Tercemarnya Sungai Cikeruh diakibatkan oleh masukan beban cemaran dari aktivitas antropogenik seperti limbah domestik, pertanian, dan industri yang memberikan suplai bahan anorganik atau unsur hara seperti nitrat dan fosfat. Ketersediaan unsur hara dapat diindikasikan oleh nilai produktivitas primer berdasarkan sebaran klorofil-a. Penelitian ini bertujuan untuk menentukan produktivitas primer serta faktor lingkungan yang mempengaruhi sebaran dan konsentrasi klorofil-a di Sungai Cikeruh. Penelitian ini dilaksanakan pada bulan Desember 2024 – Januari 2025, dengan metode survei dan teknik pengambilan sampel purposive sampling yang dilakukan di lima titik stasiun dengan 4 kali ulangan. Hasil dari pengujian kualitas air terdapat parameter yang tidak memenuhi baku mutu kualitas air berdasarkan Peraturan Pemerintah No. 22 Tahun 2021 yakni BOD dan DO. Nilai rata-rata BOD tidak memenuhi kelas 2 maupun kelas 3 pada setiap stasiunnya, sedangkan nilai rata-rata DO pada Stasiun 2 dan 4 tidak memenuhi baku mutu kelas 2  dan pada Stasiun 5 tidak memenuhi baku mutu kelas 3. Nilai konsentrasi klorofil-a di dapatkan nilai rata-rata 0,135-0,613 mg/L, berdasarkan uji statistik One-way anova konsentrasi klorofil-a didapatkan nilai p-value 0,086 > taraf signifikansi, yang diartikan tidak terdapat perbedaan yang signifikan pada setiap stasiunnya, hal ini dikarenakan perairan Sungai Cikeruh tergolong pada perairan oligotrofik melalui perhitungan produktivitas primer yang didapatkan yakni nilai rata-rata 15,998 – 40,300 mgC/m3/hari, hal ini menandakan bahwa unsur hara dan produktivitas pada Sungai Cikeruh tergolong rendah.
