Abstract

Seagrass is a high-level flowering plant (angiospermae) that lives in shallow waters up to a depth of 50-60 meters and can even reach a depth of 90 meters, with the highest abundance in the tidal zone. Tapadaa Village, located in Botumoito District, Boalemo Regency, is a coastal area with high seagrass ecosystem potential. Local people use seagrass beds for various economic activities such as collecting gastropods (snails) and sea cucumbers, fishing, and as a boat mooring area. However, these activities can potentially threaten seagrass's survival in the area. This study aims to identify the types of seagrasses and calculate their composition and density in the waters of Tomini Bay, Tapadaa Village. The study was conducted in May 2024 using a 50x50 cm quadrant method. The data collected includes species composition and seagrass density. The results of the study showed that there were nine types of seagrasses in the waters of Tomini Bay, Tapadaa Village, namely Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halodule pinifolia, Halodule uninervis, Halophila ovalis, Syringodium isoetifolium, Thalasia hemprichi, and Thalassodendron ciliatum. The most dominant species was Halodule pinifolia (37.18%), followed by Cymodocea rotundata (30.06%). Meanwhile, the species with the lowest composition was Enhalus acoroides (0.14%). The total density of seagrass reached 5.403.16 ind/m². These findings are expected to provide vital information for conservation efforts and management of seagrass ecosystems in the area.

Abstract

The Bone River faces potential pollution due to human activities around it. To ensure this, macrozoobentos are used as bioindicators by utilizing the characteristics of their constituent communities that exhibit sedentary behavior, limited mobility, and sensitivity to aquatic conditions. This study aims to examine the abundance and diversity of macrozoobentos in the Bone River and Bolango River, Gorontalo Province. The research was conducted from May to August 2023 at several observation stations on both rivers. The identification results showed a total of 127 macrozoobentos individuals consisting of 72 individuals in the Bone River and 55 individuals in the Bolango River, with the dominance of the Baetidae (PlatyBaetis) and Hydropsychidae (Cheumatopsyche and Hydropsyche) families that are widespread in both locations. A low dominance index indicates the absence of a single species that dominates significantly, while the fairly diverse distribution of taxa reflects relatively good water quality conditions in both rivers. These findings serve as an important basis for the sustainable monitoring and management of aquatic resources in the region.

Abstract

Judul : Level Kualitas Perairan Bagian Hilir Sungai Paguyaman, Gorontalo, Indonesia: Suatu Kajian Berdasarkan Distribusi Mikroalga dan Indeks SaprobikLatar Belakang: Sungai Paguyaman membentang sepanjang 136,25 km dan merupakan daerah aliran sungai terbesar kedua di Provinsi Gorontalo. Bagian hilir sungai ini bermuara di Teluk Tomini dan berada di perbatasan antara Desa Girisa Kecamatan Paguyaman Kabupaten Boalemo dan Desa Bilato Kecamatan Boliyohuto Kabupaten Gorontalo. Bagian hilir sungai ini menjadi sumber penghidupan bagi masyarakat di sekitarnya, namun kualitas perairannya terancam akibat pencemaran organik yang berasal dari aktivitas domestik dan pertanian.  Tujuan dari penelitian ini adalah untuk mengidentifikasi jenis dan distribusi mikroalga, dan menilai kualitas perairan menggunakan indeks saprobik di wilayah hilir Sungai Paguyaman, Gorontalo.Metode: Pengambilan sampel dilakukan pada empat stasiun dengan masing-masing tiga ulangan, dimulai dari stasiun 1 tepat di bibir muara sungai, kemudian disusul stasiun 2 hingga 4 dengan jarak antar stasiun 3-4 km. Mikroalga yang diamati mencakup mikroalga planktonik (fitoplankton) dan mikroalga yang melekat pada substrat batu (perifiton). Sementara parameter fisik perairan mencakup kedalaman air, suhu, kecepatan arus, kecerahan, dan substrat dasar, serta parameter kimia perairan mencakup pH, oksigen terlarut (DO), dan salinitas.Hasil: Hasil penelitian menunjukkan bahwa mikroalga yang ditemukan di wilayah hilir Sungai Paguyaman berasal dari 10 kelas yang terdiri dari 101 spesies dan 45 genus. Komposisi terbanyak berasal dari kelas Bacillariophyceae.Simpulan: Berdasarkan nilai indeks keanekaragaman (H'), indeks dominansi dan indeks keseragaman mikroalga, perairan secara umum berada dalam kategori komunitas stabil dengan keberadaan atau kepadatan biota yang merata. Nilai indeks saprobik (SI) 1,64 dan nilai indeks keadaan trofik (TSI) 0,65 menunjukkan bahwa tingkat saprobitas wilayah hilir Sungai Paguyaman saat ini berada pada tingkat Oligo/b-mesosaprobik yaitu termasuk pada kategori tercemar ringan. Temuan ini mengindikasikan bahwa perairan di hilir sungai mengalami penurunan kualitas yang dapat berdampak pada kesehatan ekosistem dan masyarakat. ABSTRACT Background: Paguyaman River stretches for 136.25 km and represents the second largest drainage basin in Gorontalo Province. Its downstream area of the river empties into Tomini Bay and is located on the border between Girisa Village, Paguyaman Subdistrict, Boalemo Regency, and Bilato Village, Boliyohuto Subdistrict, Gorontalo Regency. This regions constitutes a vital source of livelihood for the local community. However, organic pollution from domestic and agricultural activities threatens the quality of its waters. The objective of this study is to identify the types and distribution of microalgae and assess water quality using saprobic index in the downstream area of Paguyaman River, Gorontalo.Method: Sampling was conducted at four stations with three replications per station. The sampling began at station 1, located at the river mouth, and continued to stations 2 through 4, with a distance of 3-4 km between stations. Microalgae observed included planktonic microalgae (phytoplankton) and microalgae attached to rock substrates (periphyton). The physical parameters included water depth, temperature, current velocity, brightness, and bottom substrate, while the chemical parameters included pH, dissolved oxygen (DO), and salinity.Result: The findings revealed that microalgae in the downstream area of the Paguyaman River came from 10 classes of 101 species and 45 genera. The most significant composition comes from the Bacillariophyceae class. Conclusion: According to the diversity index (H'), dominance index, and uniformity index of microalgae, the waters are generally classified as stable communities, characterized by the presence or density of biota that are evenly distributed. The Saprobic Index (SI) value of 1.64 and the Trophic Status Index (TSI) value of 0.65 indicate that the saprobity level of the downstream area of the Paguyaman River is currently at the Oligo/b-mesosaprobic level, which is included in the lightly polluted category. This finding indicates that the river downstream is experiencing degrading, potentially affecting the health of the ecosystem and the surround community.

Abstract

Fase bulan merupakan faktor lingkungan alami yang memengaruhi distribusi ikan di perairan secara spasial dan temporal. Penelitian ini bertujuan untuk membandingkan komposisi dan kelimpahan ikan gobi di Sungai Bone Provinsi Gorontalo pada fase bulan gelap dan terang. Pengambilan sampel dilakukan di tiga stasiun sepanjang Sungai Bone Provinsi Gorontalo pada pukul 08.00 hingga 15.00 WITA. Waktu pengambilan sampel dilakukan pada fase bulan gelap dan terang masing-masing pada 1 Dzulhijjah 1446 Hijriyah (bulan gelap) dan pada 13 Dzulhijjah 1446 Hijriyah (bulan terang). Hasil identifikasi menunjukkan terdapat 9 spesies ikan gobi pada bulan terang dan 8 spesies pada bulan gelap, dengan Sicyopterus longifilis sebagai spesies dominan. Hal ini mengindikasikan bahwa komposisi dan kelimpahan ikan gobi di Sungai Bone Gorontalo dapat saja dipengaruhi oleh fase blulan. Namun berdasarkan uji korelasi non parametrik Spearman, tidak terdapat hubungan antara fase bulan dengan jumlah individu maupun kelimpahan relatif ikan gobi di Sungai Bone

Abstract

Lamun memainkan peran vital dalam ekosistem pesisir, termasuk sebagai penyedia jasa ekosistem, habitat berbagai organisme laut, serta indikator kesehatan lingkungan perairan. Banyaknya peranan lamun tidak diiringi dengan penambahan luasannya. Luas lamun secara global mengalami penurunan, terutama karena dampak aktivitas manusia. Teluk Tomini Gorontalo, yang memiliki garis pantai sepanjang 572,5 km, menyimpan potensi sumber daya lamun yang cukup besar. Penelitian ini bertujuan untuk mengkaji sebaran, kerapatan, dan status kesehatan lamun di Perairan Teluk Tomini Gorontalo. Penelitian dilakukan di enam lokasi, tiga di perairan Teluk Tomini Kota Gorontalo dan tiga di Kabupaten Gorontalo. Tahapan penelitian terdiri dari dua tahapan yakni identifikasi dan pencatatan lamun menggunakan metode kuadrat pada transek sepanjang 100 m sejajar garis pantai dan kajian status kesehatan lamun melalui analisis tutupan lamun. Hasil penelitian menunjukkan bahwa terdapat sepuluh jenis lamun yakni Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halophilla minor, Halophilla ovalis, Halodule pinifolia, Halodule uninervis, Thalassodendron ciliatum, Thalasia hemprichi, dan Syringodium isoetifolium, dengan C. rotundata memiliki kerapatan tertinggi (110,42 tegakan/m2). Tutupan lamun di perairan Teluk Tomini Gorontalo tergolong jarang-sedang, dengan kondisi kesehatan bervariasi dari rusak/miskin hingga rusak/kurang kaya/kurang sehat. Temuan ini menunjukkan bahwa meskipun potensi lamun besar, kondisi ekosistemnya memerlukan perhatian serius untuk menjaga keberlanjutan ekosistem dan kualitas lingkungan perairan.

Abstract

Microalgae such as Chlorella sp. are valuable for their potential in sustainable food, feed, and bioenergy production, but their cultivation often relies on costly synthetic nutrients. Exploring alternative nutrient sources, such as liquid organic fertilizers, may offer a more economical and environmentally friendly approach to biomass production. This study aims to evaluate the effect of liquid organic fertilizer application on the growth of Chlorella sp. in a closed culture system. Seven treatments were used: one control without fertilizer (K) and six treatments with increasing fertilizer doses (P1–P6). The observed parameters included initial and final cell density, as well as daily growth rate during a seven-day incubation period. The results showed that fertilizer application had a significant effect on the growth enhancement of Chlorella sp. The highest final cell density was recorded in treatment P6, exceeding 6.3 × 10⁷ cells/ml, while a population decline was observed in the control group. The daily growth rate also increased with higher fertilizer doses, with the highest value (μ = 0.36) observed in P6. Linear regression analysis showed a strong relationship between fertilizer amount and growth rate (r = 0.8493; p = 0.0156; R² = 0.7213), indicating that growth variation could be significantly explained by the amount of fertilizer applied. The conclusion of this study is that liquid organic fertilizer has great potential as an efficient and environmentally friendly alternative for microalgae culture media. Proper dosage formulation can support optimal microalgal biomass production. Further research is needed to identify the dominant nutrient content in the fertilizer and to assess the biomass quality for potential applications in food, feed, or bioenergy sectors.

Abstract

Pangandaran Reservoir, located in Pangandaran Regency, West Java, serves as a water conservation facility and supports aquaculture activities. Its water quality, particularly in terms of dissolved oxygen (DO) and biochemical oxygen demand (BOD₅), is a key indicator for maintaining the reservoir's ecological and socio-economic functions. This study aims to analyze DO and BOD₅ parameters in Pangandaran Reservoir and evaluate their compliance with applicable water quality standards. Sampling was conducted in May 2025 at four stations representing both the inflow area and the inner reservoir waters. DO levels were measured using the Winkler titration method, while BOD₅ was determined based on the difference in DO concentrations before and after a five-day incubation period. The results showed that water temperatures ranged from 32 to 32.5°C, slightly exceeding the water quality threshold, likely due to high solar radiation and limited vegetation cover. The pH ranged from 7 to 9, which is still within the safe range, with higher pH values observed in the inflow area, influenced by the dominance of limestone (karst) formations in the surrounding Pangandaran region. The highest DO concentration was recorded at Station 4 (4.32 mg. L-1), while the lowest was at Station 2 (3.40 mg. L-1). Conversely, the highest BOD₅ values were found at Station 2 (8.3 mg. L-1) and Station 1 (8 mg. L-1). The spatial distribution pattern indicates a negative relationship between DO and BOD₅, where high organic pollutant loads in the inflow area reduce dissolved oxygen levels. Overall, the water quality of Pangandaran Reservoir falls within Class 2 to Class 4 based on Government Regulation No. 82 of 2001, with signs of declining quality in the inflow area. Therefore, pollution source control and routine monitoring are essential to preserve the aquatic ecosystem of the reservoir.
